Abstract
Description
Technical Field
[0001] This utility model relates to the field of door lock technology, and more specifically, to an anti-lock positioning structure for an eco-friendly door lock. Background Technology
[0002] A door lock is a commonly used door security device to prevent unauthorized intrusion. It typically includes a lock body, a door handle installed on the inside and outside of the door, and a square shaft that links the inside and outside handles. The door lock is opened by turning the door handle, which causes the bolt to retract into the lock body.
[0003] Eco-friendly door locks, by integrating the locking component into the outer handle and the deadbolt component into the inner handle, boast a simple overall structure and novel appearance, gaining market acceptance. When the deadbolt button is pushed, the locking component is driven by a linkage plate to lock the outer handle onto the base, achieving deadbolt locking. To unlock, the deadbolt button is pushed in the opposite direction, and the locking component is driven by the linkage plate to unlock. In other words, by pushing the deadbolt button, the lock can be switched between the deadbolt and unlock positions, enabling deadbolt and unlock operations. However, existing eco-friendly door locks are prone to deadbolt buttons becoming loose and unstable in the deadbolt position, affecting the locking effectiveness. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-locking positioning structure for an eco-friendly door lock.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] An anti-lock positioning structure for an eco-friendly door lock includes a door handle, a rotating component rotatably disposed within the door handle, and an anti-lock button. The anti-lock button is slidably disposed on the door handle, and a pressing head at one end of the anti-lock button passes through the inner handle and cooperates with the rotating component. An elastic positioning component is disposed within the door handle, and elastic deformation portions are provided on the middle of both the left and right sides of the elastic positioning component.
[0007] When the deadbolt slides from the unlock position to the deadbolt position or from the deadbolt position to the unlock position, the two sides of the clamping head will respectively squeeze outwards the corresponding elastic deformation parts.
[0008] The present invention further comprises: an upper guide surface inclined on the left and right sides of the upper end of the pressing head, and a lower guide surface inclined on the left and right sides of the lower end.
[0009] The present invention is further provided that the elastic positioning member is U-shaped.
[0010] The present invention further includes: a mounting bracket for installing an elastic positioning component is provided on the square shaft sleeve inside the door handle, and the left and right ends of the mounting bracket are provided with mounting grooves that are respectively adapted to the left and right sides of the elastic positioning component.
[0011] The beneficial effects of this utility model are as follows: The anti-locking positioning structure includes a door handle, a rotating component rotatably disposed within the door handle, and an anti-lock button. The anti-lock button is slidably disposed on the door handle, and a pressing head at one end of the anti-lock button penetrates the inner handle and cooperates with the rotating component. An elastic positioning component is disposed within the door handle, and elastic deformation portions are provided inwardly on the middle of both sides of the elastic positioning component. When the anti-lock button slides from the unlock position to the anti-lock position to lock or from the anti-lock position to the unlock position to unlock, the two sides of the pressing head will respectively press outward against the corresponding elastic deformation portions. The elastic deformation portions will prevent the anti-lock button from sliding, so that only by manually pushing the anti-lock button to make the pressing head overcome the frictional force generated by the elastic deformation portions can the anti-lock button slide between the unlock position and the anti-lock position. Thus, the anti-lock button can be stably placed in the anti-lock position to ensure the anti-locking effect of the door lock. Attached Figure Description

[0019] See attached document Figures 1 to 6 The anti-lock positioning structure of an eco-friendly door lock according to this utility model is described in further detail.
[0020] An anti-locking positioning structure for an eco-friendly door lock includes a door handle 1, a rotating component 2 rotatably disposed within the door handle 1, and an anti-lock button 3. The anti-lock button 3 is slidably disposed on the door handle 1, and a pressing head 31 at one end of the anti-lock button 3 passes through the inner handle and cooperates with the rotating component 2. The rotating component 2 is provided with a spiral groove that cooperates with the pressing head 31. Pushing the anti-lock button 3 drives the rotating component 2 to rotate, and the rotating component 2 drives the locking component inside the outer door handle through a linkage plate.
[0021] The door handle 1 is equipped with an elastic positioning member 4. The elastic positioning member 4 has inwardly protruding elastic deformation portions 41 on both its left and right sides. When the deadbolt 3 slides from the unlock position to the deadbolt position to lock or from the deadbolt position to the unlock position to unlock, the two sides of the pressing head 31 will respectively press outward against the corresponding elastic deformation portions 41. These elastic deformation portions 41 will prevent the deadbolt 3 from sliding, so that only by manually pushing the deadbolt 3, allowing the pressing head 31 to overcome the frictional force generated by the elastic deformation portions 41, can the deadbolt 3 slide between the unlock and deadbolt positions. This ensures that the deadbolt 3 can be stably positioned in the deadbolt position without manual external force, guaranteeing the deadbolt effect of the door lock. Simultaneously, the deadbolt 3 can also be stably positioned in the unlock position to prevent the door lock from automatically locking itself, thus improving the structural stability of the door lock.
[0022] To facilitate the operation of the deadbolt button 3, the upper end of the clamping head 31 is provided with upper guide surfaces 311 on both the left and right sides. When unlocking, the upper end of the clamping head 31 passes through the elastic deformation part 41 under the guidance of the upper guide surfaces 311. After overcoming the elastic force of the elastic deformation part 41, the clamping head 31 moves from the deadbolt position to the unlock position. The lower end of the clamping head 31 is provided with lower guide surfaces 312 on both the left and right sides. When deadbolting, the lower end of the clamping head 31 passes through the elastic deformation part 41 under the guidance of the lower guide surfaces 312. After overcoming the elastic force of the elastic deformation part 41, the clamping head 31 moves from the unlock position to the deadbolt position.
[0023] The elastic positioning element 4 is U-shaped, and the square shaft sleeve 5 inside the door handle 1 is provided with a mounting bracket 51 for installing the elastic positioning element 4. The square shaft sleeve 5 is used to insert a square shaft. The left and right ends of the mounting bracket 51 are provided with mounting grooves 511 that are adapted to the left and right sides of the elastic positioning element 4, respectively. This ensures that the elastic positioning element 4 is stably installed on the mounting bracket 51, preventing displacement of the elastic positioning element 4 during the compression process by the pressing head 31, and improving the structural stability of the door lock.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
