Description

Technical Field

[0001] The utility model relates to the field of door closers, in particular to a catch-type door closer. Background Art

[0002] The cabinet door closer is a common furniture accessory. The door closer has a shell installed on the cabinet door and a lock seat installed in the cabinet. An elastic component is provided in the shell to connect the lock seat and the shell when the cabinet door is closed and prevent the cabinet door from opening accidentally. When the cabinet door is opened, the cabinet door and the cabinet are opened by the elastic component of the door closer.

[0003] The door closer can be installed in any cabinet doors of different sizes. The expansion of cabinet doors of different sizes requires different elastic forces pushed by the elastic component. Therefore, after the door closer is installed in the cabinet door, the elastic force of the elastic component needs to be adjusted according to the weight of the cabinet door. The existing adjustment operation of the elastic force of the elastic component in the door closer is inconvenient, resulting in a waste of labor and time costs in adjusting the elastic force of the elastic component in the door closer. Utility Model Content

[0004] The utility model solves the problem that the elastic force adjustment operation of the spring in the existing door closer is inconvenient.

[0005] The technical solution adopted by the utility model is: a catch-type door closer, including a lock seat and a shell, a main body, an inner square passage and a base are arranged in the shell, the main body is arranged in the inner square passage, a raised portion at one end of the base is arranged on the outer side of the end of the inner square passage, the main body is provided with a hook line, a tail rubber plug is arranged in the inner square passage, the hook line is buckled with or separated from the tail rubber plug, a spring is arranged between the main body and the tail rubber plug, a pair of catches are arranged at the other end of the main body, a locking pin movably connected to the catches is arranged in the lock seat, an adjusting inner tooth and an adjusting outer tooth are arranged in the base, the adjusting inner tooth is threadedly connected to the screw of the tail rubber plug, one side of the adjusting outer tooth is meshedly connected with the adjusting inner tooth, and one side of the adjusting outer tooth extends to the outer side of the shell.

[0006] Furthermore, positioning buckles are provided on both sides of the main body.

[0007] Furthermore, movable grooves are provided on both sides of the inner square passage, and the positioning buckles are arranged in the movable grooves.

[0008] Compared with the prior art, the utility model has the following beneficial effects: by rotating the outer adjusting teeth on the shell surface, the inner adjusting teeth can be driven to drive the tail rubber plug to move, thereby adjusting the size of the door gap after closing the cabinet door, and adjusting the gap between the door leaf and the cabinet body.

[0015] like Figures 1 to 5 The present invention discloses a catch-type door closer, comprising a lock base 10 and a shell 20, wherein the shell 20 is provided with a main body 21, an inner square passage 22 and a base 23, wherein the main body 21 is arranged in the inner square passage 22, and a raised portion at one end of the base is arranged at the outer side of the end of the inner square passage 22, the main body 21 is provided with a hook line 211, and a tail rubber plug 222 is arranged in the inner square passage 22, wherein the hook line 211 is connected or separated from the tail rubber plug 222, a spring 223 is arranged between the main body 21 and the tail rubber plug 22, a pair of catches 212 are arranged at the other end of the main body 21, and a lock nail 11 movably connected to the catch 212 is arranged in the lock base 10.

[0016] When the shell 20 is buckled and connected with the lock base 10, the lock nail 11 is arranged in the catch 212 to push the main body 21 to move in the direction of the tail plug 222, so that the hook line 211 in the main body 21 is buckled with the positioning block in the tail plug 222 to realize closing the door. At this time, the spring 223 is compressed. When the shell 20 is separated from the lock base 10, the lock nail 11 pushes the main body 21 to move in the direction of the tail plug 222, so that the hook line 211 is separated from the positioning block of the tail plug 222. At this time, the contracted spring 223 pushes the main body 21 outward through its own elastic force, so that the lock nail 11 is separated from the catch 212 to realize opening and closing.

[0017] How to achieve the connection and separation between the hook wire 211 and the tail rubber plug 222 is a well-known technical means in the art, and thus will not be described in detail.

[0018] The raised portion of the base 23 is provided with an adjusting inner tooth 231 and an adjusting outer tooth 232 . The adjusting inner tooth 231 is threadedly connected to the screw 224 of the tail rubber plug 222 . One side of the adjusting outer tooth 232 is meshed with the adjusting inner tooth 231 . One side of the adjusting outer tooth 232 extends to the outside of the shell 20 .

[0019] When it is necessary to adjust the elastic force of the main body 21 being ejected outward by the spring 223, the adjusting outer teeth 232 on the surface of the adjusting shell 20 can be rotated, and the adjusting outer teeth 232 drive the adjusting inner teeth 231 to drive the tail plug 222 to move, thereby adjusting the distance between the tail plug 222 and the main body 21 and the pressure of the spring 223.

[0020] In order to make the main body 21 move more stably in the inner square passage 22, positioning buckles 201 are provided on both sides of the main body 21, and moving grooves 202 are provided on both sides of the inner square passage 22. The positioning buckles 201 are arranged in the moving grooves 202. When the main body 21 moves in the inner square passage 22, the positioning buckles 201 move in the moving grooves 202 to prevent the main body 21 from shifting during movement.

[0021] In summary, the catch-type door closer of the utility model can drive the adjusting inner teeth 231 to drive the movement of the tail rubber plug 222 by rotating the adjusting outer teeth 232 on the surface of the shell 20, thereby adjusting the door gap after the internal main body is closed, and realizing the adjustment of the gap between the door leaf and the cabinet body.
