[0037] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] Please refer to Figures 1 to 6 In a first embodiment of the present invention, a reverse lock knob structure is provided, comprising: a door lock housing 10, a reverse lock knob 20, and an elastic member 30. A connecting hole is provided on the door lock housing 10, and the reverse lock knob 20 includes a first connecting member 21 and a second connecting member 22. At least a portion of the first connecting member 21 is located outside the door lock housing 10, and at least a portion of the second connecting member 22 is located inside the door lock housing 10. The first connecting member 21 has a first snap-fitting portion 211, and the second connecting member 22 has a second snap-fitting portion 221 for snap-fitting with the first snap-fitting portion 211. The second snap-fitting portion 221 is provided through the connecting hole. The elastic member 30 is provided through the second connecting member 22, with one end of the elastic member 30 abutting against the door lock housing 10 and the other end of the elastic member 30 abutting against the positioning portion 223 of the second connecting member 22.

[0039] With such a setting, by respectively arranging the first snap-fitting portion 211 and the second snap-fitting portion 221 on the first connecting member 21 and the second connecting member 22 of the anti-locking knob 20, the installation of the two parts of the anti-locking knob 20 can be completed by replacing the retaining spring with the anti-locking knob 20's own structure, and the setting of the elastic member 30 can also provide a certain locking force for the anti-locking knob 20 during installation, thereby replacing the screws to fix the anti-locking knob 20, which can effectively reduce the installation structure of the anti-locking knob 20 and improve the installation efficiency of the anti-locking knob 20.

[0040] In this embodiment, the first connector 21 includes a first connector body 212, with a first snap-fitting portion 211 disposed at an end of the first connector body 212. The second connector 22 includes a second connector body 222, with a second snap-fitting portion 221 disposed at an end of the second connector body 222. One of the first snap-fitting portion 211 and the second snap-fitting portion 221 includes a snap-fitting protrusion 23, and the other of the first snap-fitting portion 211 and the second snap-fitting portion 221 includes a snap-fitting groove 24 that snaps into engagement with the snap-fitting protrusion 23. This arrangement facilitates the connection between the first connector 21 and the second connector 22. Compared to traditional connection and fixing methods, the snap-fitting protrusion 23 and the snap-fitting groove 24 have a simpler structure and are more convenient to install, further improving the installation efficiency of the anti-lock knob 20.

[0041] Specifically, the first snap-fitting portion 211 includes a first snap-fitting block 2111, which is disposed at an end of the first connecting body 212 and protrudes from the end of the first connecting body 212, and a snap-fitting protrusion 23 is provided on the first snap-fitting block 2111. The second snap-fitting portion 221 includes a second snap-fitting block 2211, which is disposed at an end of the second connecting body 222 and protrudes from the end of the second connecting body 222, and a snap-fitting groove 24 is provided on the second snap-fitting block 2211. The arrangement of the first snap-fitting block 2111 and the second snap-fitting block 2211 facilitates the mating of the two parts of the anti-lock knob 20 through the communicating hole, thereby reducing the difficulty of installing the anti-lock knob 20 and effectively improving the installation efficiency of the anti-lock knob 20.

[0042] Specifically, the first engaging block 2111 is provided with a first mating surface 21111, and the second engaging block 2211 is provided with a second mating surface 22111 that mates with the first mating surface 21111. The engaging protrusion 23 is provided on the first mating surface 21111, and the engaging groove 24 is provided on the second mating surface 22111. The arrangement of the first mating surface 21111 and the second mating surface 22111 provides space for the arrangement of the engaging protrusion 23 and the engaging groove 24. In addition, when the engaging protrusion 23 is engaged with the engaging groove 24, the friction force generated by the engagement between the first mating surface 21111 and the second mating surface 22111 can also enhance the stability of the engagement between the two to a certain extent, making the installation and fixation more secure.

[0043] In this embodiment, the first mating surface 21111 is located on the side of the first engaging block 2111, and the second mating surface 22111 is located on the side of the second engaging block 2211, so that the first mating surface 21111 and the second mating surface 22111 are spliced ​​together. The shape of the spliced ​​structure formed by splicing the first engaging block 2111 and the second engaging block 2211 matches the shape of the connecting hole. This arrangement optimizes the splicing of the spliced ​​structure and allows the spliced ​​structure to pass smoothly through the connecting hole, thereby facilitating the installation of the anti-locking knob 20 and further enhancing the installation efficiency of the anti-locking knob 20.

[0044] Specifically, the first clamping block 2111 is a first arc-shaped block having a first arc-shaped side surface and a first mating surface 21111 connected to each other, with the first mating surface 21111 being a planar structure. The second clamping block 2211 is a second arc-shaped block having a second arc-shaped side surface and a second mating surface 22111 connected to each other, with the second mating surface 22111 being a planar structure. When the first mating surface 21111 and the second mating surface 22111 are joined, the shape formed by the first and second arc-shaped side surfaces matches the shape of the connecting hole.

[0045] In this embodiment, the first connecting member 21 further includes an operating portion 213, which is connected to the first connecting body 212 and is disposed at an end of the first connecting body 212 away from the first engaging block 2111. This arrangement facilitates user operation. When the user needs to perform an anti-locking operation, rotating the operating portion 213 can drive the anti-locking knob 20 to rotate, thereby improving the user experience.

[0046] In this embodiment, the positioning portion 223 is a positioning flange, which is disposed around the periphery of the second connecting body 222 and protrudes from the second connecting body 222. The positioning flange provides an abutment position for the installation of the elastic member 30. When the elastic member 30 is installed, one end of the elastic member 30 abuts the inner side of the door lock housing 10, and the other end abuts the positioning flange. At the same time, the positioning flange can make the installation of the elastic member 30 more stable, prevent the elastic member 30 from deviating from its movement path during operation, and ensure the stability of the installation and operation of the anti-lock knob structure.

[0047] In this embodiment, a connecting groove 2221 is provided at one end of the second connecting body 222 away from the second engaging block 2211. The connecting groove 2221 matches the shape of the reverse locking connector, and the reverse locking connector is connected to the second connecting body 222 via the connecting groove 2221. This arrangement facilitates installation with the reverse locking connector or with other functional components, thereby improving the applicability of the reverse locking knob structure.

[0048] The structural components included in this embodiment include: a first connecting member 21, an elastic member 30, a second connecting member 22, and a door lock housing 10. Specifically, the first connecting member 21 can be a locking knob head, the second connecting member 22 can be a locking knob rod, and the elastic member 30 can be a spring. Compared with a conventional locking knob, this embodiment separates the locking knob into two parts: a locking knob head and a locking knob rod.

[0049] In this embodiment, the specific structure can be: (1) Anti-locking knob head: a semi-cylinder (i.e., the first snap-fitting portion 211) is designed at the position connected to the knob rod, and a protruding tongue (i.e., the snap-fitting protrusion 23) is provided on the cross section of the semi-cylinder of the anti-locking knob head. (2) Anti-locking knob rod: a positioning flange is designed at the middle position of the rod body, and the positioning flange can be a limiting boss to replace the original retaining spring to limit the spring. A semi-cylinder (i.e., the second snap-fitting portion 221) is designed at the connection between one end of the rod and the anti-locking knob head, which is combined with the semi-cylinder on the knob head to form a complete cylinder. A slot (i.e., the snap-fitting groove 24) is provided on the cross section of the semi-cylinder of the anti-locking knob rod, and its shape and size match the tongue on the knob head.

[0050] In this embodiment, the assembly method can be as follows: first, pass the spring through the end connecting the knob rod and the knob head, then pass the knob rod through the reserved connecting hole in the door lock housing 10, so that the spring is located between the door lock housing 10 and the knob rod limiting boss. Then, push the knob rod so that the second snap-fitting portion 221 is exposed from the outer surface of the door lock housing 10, at which point the spring is compressed. Then, snap-fit ​​the knob head to the knob rod based on its structural characteristics. The length of the spring needs to be greater than the distance between the knob rod limiting boss and the inner surface of the door lock housing 10 when the knob head is pressed against the outer surface of the door lock housing 10, and there should be enough room for compression after installation. At this point, under the action of the spring's elastic force, the knob rod and knob head will be tightened and will not loosen or fall.

[0051] The structure provided in this embodiment changes the original installation method and structure, making the installation of the anti-locking knob 20 easier without affecting its stability. The presence of the spring also does not affect the feel of use, thereby improving installation efficiency and reducing costs.

[0052] In a second embodiment of the present invention, a door lock is provided, comprising the anti-lock knob structure provided in the first embodiment above.

[0053] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: by arranging the first connecting member 21 and the second connecting member 22 that are mutually clamped to form the anti-locking knob 20, the installation structure of the anti-locking knob 20 can be simplified, and the clamping setting can also ensure the connection strength to a certain extent. At the same time, the setting of the elastic member 30 can also provide a certain locking force for the anti-locking knob 20 during installation, and can replace the screws and other components that are difficult to install and disassemble in the traditional anti-locking knob structure. The use of such a structural setting can make the installation of the anti-locking knob structure more convenient, and can effectively enhance the installation efficiency of the anti-locking knob structure.
