Abstract
Description
Technical Field
[0001] This utility model relates to a lock, and more specifically, to a door lock structure. Background Technology
[0002] Most door locks installed on toilet doors on the market use a hand-held rotating mechanism for opening and closing. Due to repeated rotation, the pivot point is prone to loosening after prolonged use. This can cause the door stop, which is responsible for locking, to automatically lock even when the door is unlocked, thus closing the toilet door and preventing it from being opened from the outside in, resulting in poor overall performance. Therefore, this utility model proposes a new door lock structure. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a door lock structure that is simple in structure and easy to manufacture.
[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The door lock structure involved in this utility model includes a lock base with a mounting hole, a door stop seat rotatably connected to the lock base, a door stop plate extending radially on the door stop seat, a gripping part near the door stop seat on the door stop plate, a curved guide rail extending circumferentially on the side of the lock base, a first shoulder integrally formed on the lock base at one end of the curved guide rail, a second shoulder integrally formed on the lock base at the other end, a first positioning groove near the first shoulder and a second positioning groove near the second shoulder on the outer side of the curved guide rail, an extension portion extending axially on the door stop plate, a spring piece extending linearly towards the curved guide rail on the extension portion, and a positioning latch tongue embedded in the first positioning groove or the second positioning groove at the end of the spring piece not connected to the extension portion.
[0005] The present invention is further configured such that: an elastic element is provided between the door stop and the lock seat, with one end abutting against the door stop and the other end abutting against the lock seat.
[0006] The present invention is further configured such that the elastic element is a compression spring.
[0007] The present invention is further configured such that the included angle between the first positioning groove and the second positioning groove is 90°.
[0008] The present invention is further configured such that the gripping part, the extension part and the spring piece are all integrally integrated with the door stop.
[0009] In summary, this utility model has the following beneficial effects:
[0010] 1. Simple structure and easy to manufacture and process.
[0011] 2. In both the open and closed states, the door lock is equipped with a positioning structure to determine the corresponding state. Attached Figure Description

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.
[0016] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.
[0017] Example 1
[0018] See Figures 1 to 3 As shown, the door lock structure involved in this embodiment includes a lock base 2 with a mounting hole 1. A door stop 3 is rotatably connected to the lock base 2. A door stop plate 4 extending radially is provided on the door stop 3. A gripping part 5 near the door stop is provided on the door stop plate 4. A curved guide rail 6 extending circumferentially is provided on the side of the lock base 2. A first shoulder 7 integrally provided on the lock base is provided at one end of the curved guide rail 6, and a second shoulder 8 integrally provided on the lock base at the other end. A first positioning groove 9 near the first shoulder and a second positioning groove 10 near the second shoulder are provided on the outer side of the curved guide rail 6. An extension 11 extending axially is provided on the door stop plate 4. A spring piece 12 extending linearly towards the curved guide rail is provided on the extension 11. A positioning latch 13 embedded in the first positioning groove or the second positioning groove is provided at the end of the spring piece 12 not connected to the extension.
[0019] Furthermore, the included angle between the first positioning groove 9 and the second positioning groove 10 is 90°.
[0020] In this embodiment, by holding the gripping part 5 and turning the door stop 4, the door stop seat 3 rotates relative to the lock seat 2, thereby changing the insertion position of the positioning bolt 13. When the positioning bolt 13 is inserted into the first positioning groove 9, the door lock remains open; when the positioning bolt 13 is inserted into the second positioning groove 12, the door lock remains closed.
[0021] The curved guide rail 6 serves as a guide for the door stop 4 and the extension 11 when they rotate.
[0022] The first shoulder 7 and the second shoulder 8 are used to limit the rotation of the door stop 4 and the extension 11.
[0023] Example 2
[0024] See Figures 1 to 3 As shown, the door lock structure involved in this embodiment is further configured based on embodiment 1, wherein an elastic element 14 is provided between the door stop 3 and the lock seat 2, with one end abutting against the door stop and the other end abutting against the lock seat, and the elastic element 14 is a compression spring.
[0025] In this embodiment, an elastic element 14 is provided between the door stop 3 and the lock seat 2 to prevent loosening between the door stop 3 and the lock seat 2, which rotate relative to each other.
[0026] Example 3
[0027] See Figures 1 to 3 As shown, the door lock structure involved in this embodiment is further configured, based on embodiment 1, such that the gripping part 5, the extension part 11 and the spring piece 12 are all integrally formed with the door stop 4.
[0028] In this embodiment, by setting the gripping part 5, the extension part 11 and the spring piece 12 as an integral structure with the door stop 4, it is convenient to manufacture in one piece and simplify the processing technology of the door stop 4 and its components.
[0029] The door lock structure involved in this utility model has the characteristics of simple structure and convenient manufacturing and processing. In addition, the door lock is provided with a positioning structure to position the corresponding state in the open and closed states. The overall function is complete and the practicality is strong.
