Description

Technical Field

[0001] This utility model relates to the field of buckle technology, and in particular to a snap-fit ​​strap buckle. Background Technology

[0002] In various backpacks, tool bags, outdoor equipment and other products, the strap buckle is the key component that enables the quick connection and disconnection of the straps. Its ease of use and connection stability directly affect the user experience of the product.

[0003] In the prior art, the strap buckle usually consists of a male buckle and a female buckle. The male buckle has protruding pins, and the female buckle has corresponding slots. The buckle is fixed by the engagement of the pins and the slots.

[0004] However, this type of snap fastener has obvious drawbacks when separating: when it is necessary to separate the male and female snap fasteners, the user must first press the elastic pins on both sides of the male snap fastener to disengage the protrusion from the female snap fastener's slot. During this process, the male and female snap fasteners must be pulled towards both ends simultaneously to complete the separation. This operation method not only requires the cooperation of both hands and is cumbersome, but also makes it easy to cause separation difficulties due to improper operation in scenarios where one hand is used or the hand is not in a position to exert force, causing inconvenience to the user.

[0005] Therefore, it is necessary to provide a snap-on strap buckle to solve the above-mentioned technical problems. Utility Model Content

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0029] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a snap-fit ​​shoulder strap buckle provided by this utility model; Figure 2 for Figure 1 The diagram shows the male fastener structure. Figure 3 for Figure 1 The diagram shows the female buckle structure. Figure 4 for Figure 1 The diagram shows a cross-sectional view of the female buckle. Figure 5 for Figure 4 The enlarged schematic diagram of part A is shown. A snap-fit ​​shoulder strap buckle includes: a female buckle 1, the female buckle 1 including a housing 11 and a snap-fit ​​groove 12, the snap-fit ​​groove 12 being respectively formed at the top and bottom of the housing 11;

[0030] Male buckle 2, which is disposed on one side of female buckle 1, includes mounting component 21, two elastic strips 22 and two snap-fit ​​blocks 23. The two elastic strips 22 are respectively fixedly installed on the top and bottom of one side of mounting component 21, and the two snap-fit ​​blocks 23 are respectively fixedly installed on one end of the two elastic strips 22.

[0031] The plug-in rod 3 is fixedly installed on one side of the mounting component 21;

[0032] Limiting frame 4, the limiting frame 4 is fixedly installed on the inner side of the outer shell 11;

[0033] A pushing component 5 is disposed on the inner side of the limiting frame 4. The pushing component 5 includes a first spring 51 and a moving plate 52. The first spring 51 is disposed on the inner side of the limiting frame 4, and the moving plate 52 is disposed at one end of the first spring 51.

[0034] The elastic strip 22 has a certain degree of elasticity and is used to snap the snap block 23 into the inner side of the snap groove 12 during use.

[0035] The plug rod 3 is disposed on the inner side of the limiting frame 4, and one end of the plug rod 3 abuts against one side of the moving plate 52.

[0036] The plug rod 3 and the limiting frame 4 are compatible and can limit the plug rod 3, making it easier for the moving plate 52 to push the plug rod 3.

[0037] A second connecting groove 7 is provided on one side of the outer casing 11.

[0038] The second connecting groove 7 allows one end of the braided belt to be connected to the female buckle 1.

[0039] The other side of the mounting component 21 is provided with a first connecting groove 6, and a baffle 61 is fixedly installed on the inner side of the first connecting groove 6.

[0040] By setting the first connecting groove 6 and the stop bar 6, one end of another braided belt can be connected to the male buckle 2.

[0041] The top and bottom of the limiting frame 4 are provided with sliding grooves 8, and the inner sides of the two sliding grooves 8 are slidably connected to limiting blocks 81. The two limiting blocks 81 are respectively fixedly installed on the top and bottom of the moving plate 52.

[0042] By setting the limiting block 81 and the slide 8, when the moving plate 52 moves, it can drive the limiting block 81 to move on the inner side of the slide 8, thereby limiting the moving plate 52 and preventing the moving plate 52 from detaching from the inner side of the limiting frame 4.

[0043] The working principle of the snap-on shoulder strap buckle provided by this utility model is as follows:

[0044] When it is necessary to connect the male buckle 2 and the female buckle 1, the insertion rod 3 of the male buckle 2 is aligned with the limiting frame 4 of the female buckle 1 and inserted. During the insertion process, the insertion rod 3 pushes the moving plate 52 to move, and the moving plate 52 compresses the first spring 51. At the same time, the snap-fit ​​block 23 on the elastic strip 22 of the male buckle 2 retracts inward under the pressure of the outer shell 11. When the snap-fit ​​block 23 moves to the snap-fit ​​groove 12, the elastic strip 22 restores its deformation, and drives the snap-fit ​​block 23 to snap into the snap-fit ​​groove 12, thus completing the connection and fixation between the male buckle 2 and the female buckle 1.

[0045] When it is necessary to separate the male buckle 2 and the female buckle 1, press the snap-fit ​​blocks 23 on the top and bottom of the outer shell 11 to disengage the snap-fit ​​blocks 23 from the snap-fit ​​groove 12. At this time, the compressed first spring 51 recovers its deformation and pushes the moving plate 52 to move. The moving plate 52 pushes the plug rod 3 to pop the male buckle 2 out of the female buckle 1, thus completing the separation.

[0046] Compared with related technologies, the snap-fit ​​shoulder strap buckle provided by this utility model has the following advantages:

[0047] By setting the push component 5, when separating the male buckle 2 and the female buckle 1, after pressing the snap-fit ​​block 23 to disengage it from the snap-fit ​​groove 12, the first spring 51 can automatically push the moving plate 52, which in turn pushes the plug rod 3 to pop out the male buckle 2. There is no need to manually pull the male buckle 2 and the female buckle 1, which simplifies the operation steps. Even in scenarios where one hand is used or the hand is not in a position to exert force, the separation operation can be easily completed, which improves the convenience of use. Example

[0048] Please refer to the following: Figure 6 Based on the snap-fit ​​shoulder strap buckle provided in the first embodiment of this application, the second embodiment of this application proposes another snap-fit ​​shoulder strap buckle. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0049] Specifically, the second embodiment of this application provides a snap-fit ​​shoulder strap buckle that differs in that the snap-fit ​​shoulder strap buckle has sliding cavities 9 at both the top and bottom of the movable plate 52, and a second spring 91 is fixedly installed on the inner side of the sliding cavity 9, and a limit plate 92 is fixedly installed on one end of the second spring 91.

[0050] The limiting plate 92 is fixedly installed on the side of the limiting block 81.

[0051] By setting the limiting plate 92, it can limit the limiting block 81 during use, preventing the limiting block 81 from completely detaching from the moving plate 52.

[0052] The working principle of the snap-on shoulder strap buckle provided by this utility model is as follows:

[0053] When the elasticity of the first spring 51 decreases after prolonged use and needs to be replaced, the user uses a tool to push the two limiting blocks 81, causing one end of the two limiting blocks 81 to slide the limiting plate 92 on the inner side of the slide cavity 9, thereby squeezing the second spring 91 and moving the limiting blocks 81 away from the slide groove 8. At this time, the first spring 51 pushes the moving plate 52 out from the inner side of the limiting frame 4, and the user can then disassemble and replace the first spring 51.

[0054] Compared with related technologies, the snap-fit ​​shoulder strap buckle provided by this utility model has the following advantages:

[0055] The sliding cavity 9, the second spring 91, and the limiting plate 92 work together to replace the first spring 51 after prolonged use when its elasticity decreases, thereby increasing the overall service life of the socket.

[0056] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
