The present disclosure discloses a door closer stopper, comprising a housing mounted around a door closer, a finger press block assembly and a stop assembly disposed in the housing. The housing is provided with a slot and an opening; The finger press block assembly comprises a press block and a rotary press block hinged to the slot of the housing, and a positioning mechanism limiting the rotary press block at a position propping a catch plate; The stop assembly comprises the catch plate with a central through hole to allow the pull rod of the door closer to extend therethrough, the catch plate is perpendicular to the pull rod and has a top end in a scope of movement of the rotary press block, the rotary press block can abut against the top end of the catch plate to make the catch plate incline when the rotary press block rotates to a certain position. The present disclosure is overly compact and reasonable in structure, simple and easy to operate, and practical, safe and reliable. The user does not need to replace the original door closer and only needs to additionally install the present disclosure to perform an easy switch between several working states. The door can be positioned and remain an open state at any opening angle, and can quickly resume an auto door closing function. The present disclosure is adapted for various ordinary tubular door closers and has a broad application prospect.

1. A door closer stopper comprising: a housing mounted around a door closer, being provided with a slot connected to a finger press block assembly, and an opening allowing a pull rod of the door closer to extend therethrough;the finger press block assembly comprising a press block hinged to the slot of the housing at an uppermost position to allow a user to apply a downward pressing force, a rotary press block hinged to the slot of the housing and rotating synchronously with the press block, and a positioning mechanism limiting said rotary press block at a position propping a catch plate; anda stop assembly disposed in the housing, comprising the catch plate with a central through hole to allow the pull rod of the door closer to extend therethrough, the catch plate is perpendicular to the pull rod and has a top end, the rotary press block abuts against the top end of the catch plate to make the catch plate incline when the rotary press block rotates to a certain position;wherein said positioning mechanism comprises a first limiting mechanism for limiting a rotation angle of the rotary press block, and a second limiting mechanism enabling the press block to remain in a pressed-down state when the press block is pressed down;wherein said first limiting mechanism comprises a notch provided at a tail portion of the rotary press block, and a first limiting hub fixed to the slot of the housing, disposed at a position corresponding to said notch and being capable of limiting the rotation angle of the rotary press block;wherein said second limiting mechanism comprises a second limiting hub and a second elastic return element disposed in the rotary press block, said second limiting hub is mounted in an elongate hole of the rotary press block and is movable towards a tail portion or a head portion of the rotary press block along the elongate hole, said second elastic return element applies a force to the second limiting hub to allow it to abut against the first limiting hub all the time, and said second limiting hub moves below the first limiting hub when the press block is in a pressed-down state. 2. The door closer stopper according to claim 1, wherein said finger press block assembly further comprises a dial piece hinged to slot of the housing, the dial piece is connected to a first elastic return element, the first elastic return element applies a force to the dial piece to allow it to rotate counterclockwise, the dial piece abuts against a top end of the catch plate to make the catch plate incline when the dial piece rotates to a certain position. 3. The door closer stopper according to claim 2, wherein said press block, said rotary press block and said dial piece are coaxially hinged to the slot of the housing. 4. The door closer stopper according to claim 1, wherein said stop assembly comprises a fixing sheet, a return spring and the catch plate which are mounted in order, central through holes of the three members are coaxial with an opening of the closed end of the housing, the fixing sheet sandwiches the return spring and the catch plate in a gap between the fixing sheet and an inner side of the closed end of the housing. 5. The door closer stopper according to claim 1, wherein two nicks are symmetrically provided on an edge of the central through hole of the catch plate in a horizontal direction. 6. The door closer stopper according to claim 4, wherein said fixing sheet is L-shaped and has a raised mounting leg inserted and fixed inside the closed end of the housing. 7. The door closer stopper according to claim 1, wherein a cross section of said housing is shaped and sized to match the door closer, an end of the housing is open and this end is provided with a fastener for fastening the stopper to the door closer, the other end of the housing is closed and the center of this other end is provided with an opening allowing the pull rod of the door closer to extend therethrough. 8. A door closer stopper comprising: a housing mounted around a door closer, being provided with a slot connected to a finger press block assembly, and an opening allowing a pull rod of the door closer to extend therethrough;the finger press block assembly comprising a press block hinged to the slot of the housing at an uppermost position to allow a user to apply a downward pressing force, a rotary press block hinged to the slot of the housing and rotating synchronously with the press block, and a positioning mechanism limiting said rotary press block at a position propping a catch plate; anda stop assembly disposed in the housing, comprising the catch plate with a central through hole to allow the pull rod of the door closer to extend therethrough, the catch plate is perpendicular to the pull rod and has a top end, the rotary press block abuts against the top end of the catch plate to make the catch plate incline when the rotary press block rotates to a certain position;wherein said finger press block assembly further comprises a dial piece hinged to slot of the housing, the dial piece is connected to a first elastic return element, the first elastic return element applies a force to the dial piece to allow it to rotate counterclockwise, the dial piece abuts against a top end of the catch plate to make the catch plate incline when the dial piece rotates to a certain position;wherein said press block, said rotary press block and said dial piece are coaxially hinged to the slot of the housing.
