Description

Technical Field

[0001] The utility model relates to the technical field of buckles, in particular to a self-resetting triangular buckle. Background Art

[0002] Buckles are widely used in clothing, bags, sports equipment, pet leash equipment and other products. They are used to fix straps, fabrics, etc. They are usually composed of a male buckle and a female buckle, and the male buckle is inserted into the female buckle for fixation. The female buckle is provided with a bayonet, and the male buckle is provided with a center column and a bayonet pin that matches the bayonet. The male buckle and the female buckle are fixed by the engagement of the bayonet pin and the bayonet. It can be seen that the main force-bearing component of the traditional buckle is the bayonet pin, and the force is all in the same straight line, so the stability is poor and there is a risk of disengagement. Especially in low temperature environments, the toughness of the buckle is reduced due to the influence of the nylon material of the buckle itself, so the buckle is easy to disengage when under force, and the stability is poor.

[0003] The inventor of this application is committed to the research of police equipment, and in 2023 applied for a triangular buckle with publication number CN219679921U, including a female buckle and a male buckle, the female buckle includes a first connecting part and a shell connected to the first connecting part, and a first bayonet is arranged on both sides of the length direction of the shell, the male buckle includes a second connecting part, and the second connecting part is provided with two bayonet pins matching the first bayonet, a middle column connected to the second connecting part is arranged between the two bayonet pins, a limiting block is arranged at the end of the middle column, and a second bayonet matching the limiting block is arranged on the top of the shell.

[0004] The applicant found in use that although the above application solves the risk of the traditional plug buckle being easily disengaged by setting a limit block, the limiting effect of the limit block is still achieved by relying on the material of the limit block itself. In other words, under the influence of temperature, in a cold or hot environment, the material of the limit block will expand and contract, and the limit block will deform or the toughness of the material will change, which will still cause the risk of disengagement. For this reason, the present application makes further improvements. Utility Model Content

[0035] The following is combined with Figures 1 to 7 The utility model is further described.

[0036] Embodiment 1

[0037] In order to solve the technical problems existing in the background technology, the utility model provides a self-resetting triangular buckle.

[0038] In the specific technical solution, refer to Figure 1 and Figure 2, including a male buckle 1 and a female buckle 2, the male buckle 1 including a first connecting part 101, two bayonet pins 102 are arranged on the first connecting part 101, a middle column 103 connected to the first connecting part 101 is arranged between the two bayonet pins 102, the length of the middle column 103 is greater than the length of the bayonet pins 102, the female buckle 2 includes a second connecting part 201 and a shell 202 connected to the second connecting part 201, the shell 202 is a hollow square structure, and bayonet sockets 203 matching the bayonet pins 102 are arranged on both sides of the shell 202 in the width direction. During assembly, the male buckle 1 is inserted into the female buckle 2. During the insertion process, the two bayonet pins 102 on both sides of the male buckle 1 are pressed tightly into the shell 202 of the female buckle 2. During the continuous insertion process, when the bayonet pin 102 reaches the position of the bayonet socket 203, since the bayonet pin 102 is no longer restricted, the bayonet pin 102 pops out and engages with the bayonet socket 203, thereby achieving the fixation of the male buckle 1 and the female buckle 2; during disengagement, the operator squeezes the bayonet pin 102 with his fingers, and then drags the male buckle 1 to complete the disengagement.

[0039] The above structure is the same as the structure of the buckle in the prior art. In order to solve the technical problem that the triangular buckle in the prior art mentioned in the background art is easily decoupled due to the influence of ambient temperature, the utility model makes the following technical improvements: Specifically, refer to Figure 1 to Figure 7 In the present application, a cover plate 3 is arranged on the top of the second connecting part 201, and the cover plate 3 is rotatably connected to the second connecting part 201 through a rotating pin 4. A return spring (not shown in the figure) is arranged on the rotating pin 4 for driving the cover plate 3 to rotate toward the bottom of the second connecting part 201. A clamping block 301 is arranged at the bottom of the cover plate 3, and the bottom of the clamping block 301 is an inclined surface. The middle column 103 is an inclined surface matching the clamping block 301, and the thickness of the middle column 103 gradually decreases in the direction away from the first connecting part 101. A clamping groove 104 matching the clamping block 301 is arranged at a position of the middle column 103 close to the first connecting part 101.

[0040] After the male buckle 1 is inserted into the female buckle 2, when the bayonet pin 102 and the bayonet port 203 are engaged and abutted, the block 301 on the cover plate 3 is also aligned with the slot 104 on the male buckle 1. Since the return spring is provided on the rotating pin 4 of the cover plate 3, the cover plate 3 will be subjected to a force that always presses downward, and the block 301 on the cover plate 3 can be automatically clamped in the slot 104 of the male buckle 1, completing the locking of the male buckle 1 and the female buckle 2. To unlock, the operator only needs to move the cover plate upwards and squeeze the bayonet pins on both sides of the male buckle to easily unlock. It can be seen from the above structure that compared with the triangular buckle in the prior art, the utility model locks the male buckle and the female buckle by means of a card block connection, so that the triangular buckle no longer relies on its own material for locking, and is no longer restricted by temperature changes, which expands the application range of the triangular buckle and eliminates the risk of disengagement; moreover, the direction of the card block connection is perpendicular to the disengagement direction, further improving the stability of the triangular buckle; in addition, the utility model still adopts a three-point force-bearing structure to limit the horizontal displacement of the male buckle in the lateral and longitudinal directions of the buckle, forming a stable triangular surface force-bearing structure, which greatly improves the stability of the buckle.

[0041] In order to facilitate the docking of the male buckle 1 and the female buckle 2, and the smooth docking of the card block 301 and the card slot 104, refer to Figure 6 Therefore, in this embodiment, a guide groove 204 is also provided on the housing 202 to guide the middle column 103 to slide.

[0042] In order to reduce the overall weight of the triangle buckle, refer to Figure 5 Therefore, in this embodiment, a weight-reducing groove 105 is further provided on the center column 103 along the axial direction of the center column 103 .

[0043] In order to improve the elastic reset ability of the bayonet 102, refer to Figure 5 Therefore, in this embodiment, ribs 106 connected to the first connecting part 101 are also provided on both sides of the middle column 103, and an elastic paddle 107 is provided between the ribs 106 and the bayonet 102. The elastic paddle 107 is U-shaped, one end of the elastic paddle 107 is connected to the bayonet 102, and the other end is connected to the middle column 103. Since the elastic paddle is thin, its toughness is good, and it is U-shaped, so it has strong elasticity. In the process of inserting the male buckle 1 into the female buckle 2, when the bayonet 102 reaches the bayonet 203, the bayonet 102 can be quickly popped out with the help of the elastic paddle 107 to form a bite and contact with the bayonet 203, completing the fixation of the male buckle and the female buckle; and the elastic paddle applies an outward force to the bayonet, which can also well ensure that the plug buckle does not disengage, thereby improving the stability of the plug buckle. In order to improve the stability of the connection between the elastic paddle 107, the bayonet 102 and the middle column 103, the three adopt an integrated molding manufacturing process.

[0044] In order to improve the stability of the buckle, a limiting groove 108 is provided between the rib plate 106 and the center column 103 in this embodiment, and a limiting wedge 302 matching the limiting groove 108 is provided at a corresponding position on the bottom of the cover plate 3. The self-resetting cover plate is also provided with an additional limiting wedge at the position where the male buckle and the female buckle are engaged, which can ensure that the male buckle cannot be unlocked under the premise of not opening the cover plate, thereby improving the overall stability.

[0045] The triangular buckle of this embodiment is mainly used for police waist seals or police belts, but is not limited thereto. Generally speaking, police equipment must be printed with police badges, so the cover plate 3, the limiting wedge block 302 and the clamping block 301 in this embodiment are made of aluminum alloy. The cover plate 3 made of aluminum alloy facilitates the printing of police badges, and the aluminum alloy material has the advantages of light weight, high strength, and corrosion resistance; in addition, in order to improve the stability of the connection between the cover plate 3, the limiting wedge block 302 and the clamping block 301 and reduce the welding process, the cover plate 3, the limiting wedge block 302 and the clamping block 301 adopt an integrated molding manufacturing process.

[0046] In order to make the buckle fit more closely with the human body and improve the wearer's comfort, refer to Figure 3 The first connection part 101 and the second connection part 201 are bent in a slightly arc shape in a direction away from the cover plate 3, which can effectively reduce the compression or interference of the buckle on the wearer's waist, is more in line with the abdominal structure of the human body, and is more comfortable to wear.

[0047] The specific operation steps of this embodiment are as follows:

[0048] During assembly, the male buckle 1 is inserted into the female buckle 2. During the insertion process, the two bayonet pins 102 on both sides of the male buckle 1 are pressed tightly into the housing 202 of the female buckle 2. During the continuous insertion of the male buckle 1, when the bayonet pin 102 reaches the position of the bayonet port 203, since the bayonet pin 102 is no longer restricted, the bayonet pin 102 pops out and engages with the bayonet port 203. At the same time, during the insertion process, the inclined surface on the block 301 of the cover plate 3 contacts the inclined surface on the middle column 103 of the male buckle 2, and the middle column 103 gradually lifts the cover plate 3. When the bayonet pin 102 engages with the bayonet port 203, the block 301 falls into the slot 104, and the cover plate 3 presses on the surface of the female buckle 2 to complete the locking of the plug. When disengaging, the operator squeezes the bayonet pin 102 with his fingers, and then drags the male buckle 1 to complete the disengagement.

[0049] Embodiment 2

[0050] In order to increase the bite force between the card block and the card slot and improve the stability of the buckle, based on the first embodiment, the surface of the card block 301 is provided with a first magnetic material (not shown in the figure), and the surface of the card slot 104 is provided with a second magnetic material (not shown in the figure), and the first magnetic material and the second magnetic material attract each other. The first magnetic material and the second magnetic material can directly use magnets.

[0051] The above specific implementation methods further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above are only specific implementation methods of the utility model and are not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
