[0032] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0033] The utility model provides a waist buckle, comprising a first component 1 and a second component 2. Figure 1-4 As shown, the overall weight of the waist buckle is reduced, and the production cost is reduced accordingly. The technical solution of the utility model is described in detail below with a specific structure.

[0034] like Figure 3-4 As shown, the first component 1 includes a first main body 11, a fixed plate 12, a positioning column 14 and a first guide structure 13. The fixed plate 12 is fixedly connected to the first main body 11, and a locking space is formed between the first main body 11 and the fixed plate 12. The positioning column 14 is arranged between the fixed plate 12 and the first main body 11, and the first guide structure 13 is arranged between the fixed plate 12 and the first main body 11.

[0035] by Figure 4 For example, the positioning post 14 is integrally formed with the first body 11, and the fixing plate 12 covers the first body 11 and is fixedly connected to the end of the positioning post 14. Alternatively, the positioning post 14 can be integrally formed on the fixing plate 12, with the first body 11 fixedly connected to the end of the positioning post 14. Similarly, the first guide structure 13 can be provided on either the fixing plate 12 or the first body 11.

[0036] The second component 2 includes a second body 21, a locking structure 23, and a second guide structure 22. The second guide structure 22 and the locking structure 23 are disposed on the second body 21. The second guide structure 22 and the locking structure 23 enter the locking space, and the second guide structure 22 is connected to the first guide structure 13. The locking structure 23 is detachably connected to the positioning post 14. It is easy to understand that when the first component 1 and the second component 2 are connected, the first guide structure 13 and the second guide structure 22 serve as guides, and the locking structure 23 of the second component 2 enters the locking space and connects with the positioning post 14.

[0037] In the present invention, the first guide structure 13 and the second guide structure 22 can be various, and the first guide structure 13 and the second guide structure 22 contact each other to achieve a guiding function. Preferably, the first guide structure 13 is a guide rail and the second guide structure 22 is an alignment post, or the first guide structure 13 is an alignment post and the second guide structure 22 is a guide rail, wherein the alignment post moves along the guide rail and is embedded in the guide rail.

[0038] Specifically, the guide rail is provided between the first body 11 and the fixing plate 12, and the alignment post is provided on the second body 21. Figure 3 or the alignment column is provided between the first body 11 and the fixed plate 12, and the guide rail is provided on the second body 21, which is not shown in the drawings.

[0039] Preferably, the guide track is composed of two guide blocks. It is easy to understand that when the guide track is set between the first body 11 and the fixed plate 12, the two guide blocks can be set on the fixed plate 12, such as Figure 3 As shown, two guide blocks can also be set on the first body 11, which is not shown in the drawings; when the guide rail is set on the second body 21, one end of the two guide blocks is respectively connected to the second body 21, that is, the two guide blocks and the second body 21 form a shape similar to an electric plug.

[0040] In addition to guiding the connection between the first component 1 and the second component 2, the first guide structure 13 and the second guide structure 22 also play a limiting role, restricting the excessive movement of the second component 2. Taking the guide track set in the first component 1 and the alignment column set in the second component 2 as an example, after the alignment column on the second component 2 is fully embedded in the guide track, the ends of the two guide blocks will abut against the second body 21, restricting the second body 21 from continuing to move toward the first body 11.

[0041] Preferably, a first connecting column 15 is further provided between the first component 1 and the fixing plate 12, and the first connecting column 15 serves to assist in connecting the first component 1 and the fixing plate 12. Figure 3-4 As shown, the first connecting column 15 can be disposed behind the first guide structure 13 , that is, at one end of the first guide structure 13 .

[0042] Preferably, both the first body 11 and the second body 21 are provided with a webbing connection portion 3 for connecting with an external object.

[0043] In the present invention, the two guide blocks can be arranged in various ways, for example, the two guide blocks can be arranged in an "eight" shape, that is, the guide rail is in a trapezoidal shape, and the alignment post is also in a trapezoidal shape. Preferably, the two guide blocks are arranged in parallel, the guide rail is straight, and the alignment post is in a rectangular parallelepiped shape.

[0044] like Figure 3-4 As shown, the locking structure 23 includes a first connecting plate 232, a second connecting plate 233 and a locking piece. The first connecting plate 232 is fixedly connected to the second main body 21, the second connecting plate 233 covers the first connecting plate 232 and is fixedly connected, and the locking piece is arranged between the first connecting plate 232 and the second connecting plate 233. The locking piece is detachably connected to the positioning column 14.

[0045] When the second component 2 and the first component 1 need to be connected, the locking member is connected to the positioning column 14 , and when the second component 2 and the first component 1 need to be separated, the locking member is separated from the positioning member.

[0046] In the present invention, the structure of the locking member can be various. A feasible structure is proposed below:

[0047] The locking structure 23 is arranged in parallel with the second guide structure 22. The locking member includes a rotating base plate 231, a waist buckle pressing member 234, a hook member 235 and a spring 236. The side of the rotating base plate 231 facing the second guide structure 22 is the inner side of the rotating base plate 231, and the side of the rotating base plate 231 away from the second guide structure 22 is the outer side of the rotating base plate 231.

[0048] like Figure 3-4 As shown, a rotating column 237 is set between the first connecting plate 232 and the second connecting plate 233, the rotating base plate 231 is rotatably connected to the rotating column 237, the waist buckle pressing member 234 is set on the inner side of the rotating base plate 231, the return hook 235 is set on the side of the rotating base plate 231 away from the second main body 21 and the waist buckle pressing member 234 is adjacent to the return hook 235, and an introduction port 25 is formed between the waist buckle pressing member 234 and the return hook 235, and the introduction port 25 is adapted to the positioning column 14, and the rotating base plate 231 is provided with an avoidance position 24, and the avoidance position 24 is between the waist buckle pressing member 234 and the return hook 235, and the introduction port 25 is connected to the avoidance position 24, and the spring 236 is set on the inner side of the rotating base plate 231, one end of the spring 236 is connected to the rotating base plate 231, and the other end of the spring 236 is fixedly connected to the first connecting plate 232.

[0049] like Figure 1-2 As shown, the working principle of the locking structure 23 is as follows: when the second component 2 is not connected to the first component 1, under the action of the spring 236, the rotating base plate 231 rotates in the direction away from the second guide structure 22. When the second component 2 is connected to the first component 1, the return hook 235 first contacts the positioning post 14 on the same side. As the second component 2 continues to move toward the first component 1, the positioning post 14 enters the introduction port 25, causing the return hook 235 to move toward the second guide structure 22 and compress the spring 236. Subsequently, the positioning post 14 enters the avoidance position 24 of the rotating base plate 231. Subsequently, the spring 236 pushes the rotating base plate 231 to rotate in the direction away from the second guide structure 22, causing the positioning post 14 to be clamped by the return hook 235, thereby preventing the positioning post 14 from escaping from the avoidance position 24.

[0050] When the second component 2 is separated from the first component 1, force is applied from the waist buckle pressing piece 234 to compress the spring 236, align the positioning column 14 with the introduction port 25, and continue to pull out the second component 2. The positioning column 14 is disengaged along the introduction port 25, and the second component 2 is separated from the first component 1.

[0051] Furthermore, in order to facilitate the positioning post 14 to enter the avoidance position 24 of the rotating base plate 231 , the contact surface between the return hook 235 and the positioning post 14 is an inclined surface.

[0052] Furthermore, a spring fixing member 238 is provided between the first connecting plate 232 and the second connecting plate 233, the spring fixing member 238 is provided with a first mounting position, a second mounting position is provided on the inner side of the rotating base plate 231, a card point 2310 is provided in the second mounting position, one end of the spring 236 is embedded in the first mounting position, and the other end of the spring 236 is embedded in the second mounting position and is sleeved outside the card point 2310.

[0053] A plurality of second connecting posts 239 are further provided on the first connecting plate 232 , and the second connecting plate 233 is fixedly connected to the second connecting posts 239 .

[0054] In the present invention, the number of the locking structures 23 can be one or more.

[0055] Taking the number of locking structures 23 as one as an example, which is not shown in the accompanying drawings, the first guide structure 13 is arranged on one side of the locking space, the positioning column 14 is arranged on the other side of the locking space, the second guide structure 22 is arranged on one side of the second body 21, and the locking structure 23 is arranged on the other side of the second body 21, wherein the first guide structure 13 and the second guide structure 22 are on the same side, and the positioning column 14 and the locking structure 23 are on the same side.

[0056] When the second component 2 is connected to the first component 1, the locking structure 23 is connected to the positioning column 14 on the same side. At this time, the connection between the first guide structure 13 and the second guide structure 22 also plays an auxiliary locking role. Since the first guide structure 13 restricts the second guide structure 22 from escaping, after the first guide structure 13 and the second guide structure 22 are connected, the first component 1 and the second component 2 can only move along the guide direction, and the locking structure 23 can restrict the movement of the first component 1 and the second component 2 along the guide direction, thereby realizing the locking of the first component 1 and the second component 2.

[0057] Take the number of locking structures 23 as two for example, Figure 3-4 As shown, the first guide structure 13 is arranged in the middle of the locking space, the two positioning columns 14 are respectively arranged on both sides of the first guide structure 13, the second guide structure 22 is arranged in the middle of the second body 21, and the two locking structures 23 are respectively arranged on both sides of the second guide structure 22.

[0058] The usage of providing two locking structures 23 is the same as that of providing one locking structure 23 .

[0059] More preferably, the two positioning posts 14 are symmetrically arranged on the outside of the first guide structure 13 , and the two locking structures 23 are symmetrically arranged on both sides of the second guide structure 22 .

[0060] like Figure 3-4As shown, a dot 2311 is provided on one end of the waist buckle pressing member 234 facing the second main body 21. The design of the dot 2311 prevents the waist buckle pressing member 234 from directly contacting the second main body 21, making it easier for fingers to press.

[0061] The present invention proposes a new waist buckle locking structure. Except for the spring 236, all components of the first component 1 and the second component 2 can be injection molded, which greatly reduces the use of metal parts. While maintaining the waist buckle locking effect, it reduces the weight of the waist buckle, which is convenient for consumers to carry and use.

[0062] The embodiments provided by the present invention are described in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only intended to help understand the core concept of the present invention. It should be noted that, for those skilled in the art, without departing from the principles of the present invention, the present invention can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
