Description

Technical Field

[0001] This utility model relates to a lock used in bags, and more particularly to a side-sliding unlocking hardware backpack buckle. Background Technology

[0002] Backpack buckles come in a variety of types and styles. Their function is to fasten the backpack straps, allowing for strap length adjustment to accommodate people of different heights. They are widely used in school bags, backpacks, travel bags, hiking backpacks, and more.

[0003] The existing backpack buckles are generally composed of a male buckle and a female buckle, with corresponding locking mechanisms on the male buckle and female buckle to achieve the locking.

[0004] However, the existing male and female buckles are separated in the same direction as the unlocking direction. Therefore, they are prone to separation due to excessive tension from the backpack straps, resulting in poor reliability. Furthermore, the prongs on the existing male buckles are solid and lack flexibility, requiring significant force to separate them from the female buckle. In addition, the existing male and female buckles lack a guiding structure during insertion, causing the male buckle to easily deviate, hindering smooth insertion and resulting in difficulty unlocking and a poor user experience.

[0005] Therefore, there is an urgent need for a side-sliding unlocking hardware backpack buckle to overcome one or more of the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide a side-sliding unlocking hardware backpack buckle, which improves the reliability of the buckle on the one hand; on the other hand, it eliminates the need for the pin and does not require pressing the pin or other switches to unlock, and has the advantages of being convenient, quick and easy to use and providing an excellent user experience.

[0007] To achieve the above objectives, the side-sliding unlocking hardware backpack buckle of this utility model includes a first buckle body and a second buckle body for assembly and connection with the corresponding backpack strap. The first buckle body is provided with a lateral sliding cavity and a retractable spring lock assembly partially exposed in the lateral sliding cavity. The lateral sliding cavity passes through the first adjacent first side surface and the first end surface of the first buckle body respectively. The second buckle body is provided with a side slider that can slide into or out of the lateral sliding cavity from the first side surface. During the process of sliding into the lateral sliding cavity, the side slider slides to a locking position by pushing the spring lock assembly inward. When in the locking position, the side slider extends out of the first buckle body from the first end surface. The first buckle body prevents the side slider from being pulled out of the lateral sliding cavity in the direction in which the side slider extends out of the first buckle body.

[0008] Compared with existing technologies, the design of "a first buckle body having a lateral sliding cavity and a retractable spring-lock assembly partially exposed in the lateral sliding cavity, the lateral sliding cavity penetrating the adjacent first side surface and first end surface of the first buckle body, a second buckle body having a side slider that can slide into or out of the lateral sliding cavity from the first side surface, the side slider sliding to the locking position by pushing the spring-lock assembly inward during the process of sliding into the lateral sliding cavity, the side slider extending out of the first buckle body from the first end surface in the locking position, and the first buckle body preventing the side slider from being pulled out of the lateral sliding cavity in the direction in which the side slider extends out of the first buckle body" on the one hand, makes The unlocking direction is staggered with the pulling direction of the backpack strap on the first and second buckles, thus improving the reliability of the fastening. Furthermore, during unlocking, the operator only needs to hold the first buckle with one hand and the second buckle with the other, applying force to move the side slider towards the lateral sliding cavity. Before sliding, the side slider pushes the spring-loaded locking assembly inward to release it, and then slides out of the lateral sliding cavity, achieving the separation of the first and second buckles. Therefore, the pins are eliminated, and there is no need to press pins or other switches to unlock, offering advantages such as convenience, ease of use, and an excellent user experience. Additionally, the first buckle and the second buckle and side slider, which together form an integrated structure, can be manufactured using Binder Jetting 3D printing technology, CNC machining, metal injection molding, and forging, eliminating the need for mold making and significantly saving time and improving development efficiency. In addition, by using stainless steel metal powder with a diameter of less than 20 micrometers, low oxygen content, high density, low porosity, and high sphericity, it is possible to develop products with complex shapes that cannot be achieved by traditional CNC machining.

[0033] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0034] Please see Figures 1 to 4 The side-sliding unlocking hardware backpack buckle 100 of this utility model includes a first buckle body 10 and a second buckle body 20. The first buckle body 10 is used for assembling and connecting to the first backpack strap 210, and the second buckle body 20 is used for assembling and connecting to the second backpack strap 220. See details below. Figure 4 As shown.

[0035] Combined Figure 9 The first buckle body 10 is provided with a lateral sliding cavity 11 and a retractable spring lock assembly 30 partially exposed in the lateral sliding cavity 11. The lateral sliding cavity 11 penetrates the adjacent first side surface 12 and first end surface 13 of the first buckle body 10 respectively; optionally, in... Figures 8 to 11In this example, the end of the lateral sliding cavity 11 furthest from the first side surface 12 is a closed end 11a. This design ensures that the side slider 21, described below, can only slide into or out of the lateral sliding cavity 11 from the first side surface 12 of the first fastener 10, thus satisfying the need for the side slider 21 to slide into or out of the lateral sliding cavity 11 from one side only. Obviously, depending on actual needs, the end of the lateral sliding cavity 11 furthest from the first side surface 12 can also be an open end, therefore it is not considered... Figures 8 to 11 The above is the limit.

[0036] Meanwhile, the second buckle body 20 is provided with a side slider 21 that can slide into or out of the lateral sliding cavity 11 from the first side 12. During the process of sliding into the lateral sliding cavity 11, the side slider 21 slides to the locking position where it is locked with the spring lock assembly 30 by pushing the spring lock assembly 30 inward. See the state below. Figure 6 As shown; the side slider 21 is in Figure 6 When in the locked position as shown, the side slider 21 also extends from the first end face 13 out of the first buckle body 10, as shown in the figure. Figure 1 and Figure 5 As shown. The first buckle 10, in the direction where the side slider 21 extends out of the first buckle 10 (see arrow B), prevents the side slider 21 from being pulled out of the lateral sliding cavity 11, thus preventing the first buckle 10 from accidentally disengaging under the pulling action of the first backpack strap 210 and the second buckle 20 under the pulling action of the second backpack strap 220, thereby ensuring the reliability of the connection between the first buckle 10 and the second buckle 20 after fastening. Specifically, in Figure 6 and Figures 8 to 11 In the example, the closed end 11a has a side slider 21 in Figure 6 The locking position shown is abutting the positioning surface 111, which improves the convenience of the locking operation of the first buckle body 10 and the second buckle body 20. More specifically, see the description below.

[0037] Combination Figure 1 , Figure 2 , Figure 5 and Figures 9 to 14 As an example, the first fastener 10 defines the position of the lateral sliding cavity 11 and has a blocking structure 112. The blocking structure 112 prevents the side slider 21 from being pulled out of the lateral sliding cavity 11 along the direction in which the side slider 21 extends out of the first fastener 10 (see the direction indicated by arrow B). Correspondingly, the side slider 21 has a sliding groove 211 for the blocking structure 112 to slide in or out of the lateral sliding cavity 11, so that the side slider 21 in the lateral sliding cavity 11 is prevented from being pulled out of the first fastener 10 along the direction indicated by arrow B by means of the cooperation of the blocking structure 112 and the sliding groove 211. Specifically, in Figures 12 to 14 In this example, the sliding groove 211 is arranged on one side of the side slider 21; Figures 9 to 11In this example, the blocking structure 112 is arranged on one side. This design serves two purposes: firstly, it prevents mistaken identity; secondly, because the pulling force of the first backpack strap 210 on the first buckle 10 and the pulling force of the second backpack strap 220 on the second buckle 20 are both perpendicular to the lateral sliding cavity 11, the one-sided blocking structure 112 abuts against the edge of the sliding groove 211 of the side slider 21, achieving a tight connection between the first buckle 10 and the second buckle 20. Furthermore, in... Figures 9 to 11 In this example, the blocking structure 112 extends along the sliding direction of the side slider 21 (see the opposite direction indicated by arrow A) and / or the sliding direction (see the direction indicated by arrow A) to increase the blocking position of the blocking structure 112 on the side slider 21, thereby more effectively preventing the side slider 21 from being pulled out of the first buckle body 10 in the direction indicated by arrow B, thus more effectively improving the connection stability of the first buckle body 10 and the second buckle body 20 after fastening. Furthermore, in Figures 9 to 11 In this example, the blocking structure 112 is adjacent to the first end face 13 to facilitate the manufacture of the blocking structure 112 on the first buckle body 10.

[0038] like Figure 2 , Figure 6 , Figure 8 , Figure 12 and Figure 13 As shown in the figure, as an example, the side slider 21 is provided with a locking part 212 for locking the spring lock assembly 30, and an inclined top structure 213 located in front of the locking part 212 in the direction of sliding the side slider 21 into the lateral sliding cavity 11 (see the opposite direction indicated by arrow A). The inclined top structure 213 is inclined towards the second buckle body 20 in the direction of sliding the side slider 21 into the lateral sliding cavity 11. Therefore, with the cooperation of the locking part 212 and the spring lock assembly 30, the first buckle body 10 and the second buckle body 20 are effectively prevented from falling off naturally along the lateral sliding cavity 11 under the influence of gravity or non-human subjective external force, so that the hardware backpack buckle 100 of this utility model can better meet the user requirements. With the help of the inclined top structure 213 located in front of the locking part 212, it is easier for the side slider 21 to push the spring lock assembly 30 inward during the process of sliding into the lateral sliding cavity 11. In addition, Figure 6 and Figures 8 to 11 In the example, the spring lock assembly 30 is exposed from the bottom surface 113 of the lateral sliding cavity 11. The bottom surface 113 and the first end face 13 are opposite each other, that is, the bottom surface 113 is opposite to the first end face 113 in the direction indicated by arrow B. This design allows the first buckle body 10 to be positioned in its thickness direction (see...). Figure 9 It is made thinner in the left and right directions. Furthermore, in Figure 6 and Figures 8 to 11As an example, the first buckle body 10 has a mounting hole 14 for mounting the spring lock assembly 30. The mounting hole 14 penetrates the bottom surface 113 of the cavity, thus facilitating the assembly operation of the spring lock assembly 30 onto the first buckle body 10. Specifically, in Figure 6 and Figures 8 to 11 In this example, the spring-locking assemblies 30 are two spaced apart from each other in the direction in which the side slider 21 slides into the lateral sliding cavity 11. Each spring-locking assembly 30 has a corresponding locking part 212 to increase the locking capability of the spring-locking assembly 30 to the side slider 21. Obviously, depending on actual needs, there may be one, three, or four spring-locking assemblies 30, so it is not limited to one. Figure 6 and Figures 8 to 11 The number of locking parts 212 is preferably equal to the number of spring-loaded lock assemblies 30, to meet the requirement that each spring-loaded lock assembly 30 cooperates with a corresponding locking part 212. More specifically, in Figure 6 and Figures 8 to 11 In the middle, the spring lock assembly 30 includes a sleeve 31 installed in the mounting hole 14, a spring 32 and a locking ball 33 placed in the sleeve 31; the locking ball 33 extends partially out of the sleeve 31 from the opening 311, and the sleeve 31 is provided with a limiting structure 312 and a vent hole 313 opposite to the opening 311 (see Figure 7 The vent 313 ensures that the atmospheric pressure inside the sleeve 31 remains consistent with the external pressure, preventing the locking ball 33 from getting stuck inside the sleeve 31. The spring 32 abuts against both the locking ball 33 and the sleeve 31, keeping the locking ball 33 in contact with the limiting structure 312 to prevent it from accidentally falling off the sleeve 31. The locking part 212 is a recess to facilitate locking and unlocking operations between the locking ball 33 and the locking part 212. It should be noted that when the spring-loaded locking assembly 30 is made as a module independent of the first buckle body 10, the assembly operation of the spring-loaded locking assembly 30 on the first buckle body 10 becomes more convenient. Furthermore, the spring-loaded locking assembly 30 can be fixed in the first buckle body 10 through an interference fit between the sleeve 31 and the mounting hole 14. Obviously, depending on actual needs, other methods well-known in the art can also be used to secure the spring-loaded locking assembly 30 to the first buckle body 10.

[0039] like Figures 1 to 4 , Figure 6 and Figures 8 to 13As shown, as an example, the end of the first buckle body 10 away from the first end face 13 is provided with a first through hole 15 for the first backpack strap 210 to pass through and wrap around, so as to facilitate the operation of the first backpack strap 210 passing through and wrapping around the first buckle body 10; the end of the second buckle body 20 away from the side slider 21 is provided with a second through hole 22 for the second backpack strap 220 to pass through and wrap around, so as to facilitate the operation of the second backpack strap 220 passing through and wrapping around the second buckle body 20. Specifically, in Figure 3 In the diagram, both the first through hole 15 and the second through hole 22 are square holes with rounded corners. Obviously, depending on actual needs, the shapes of the first through hole 15 and the second through hole 22 can also be other shapes, therefore, they are not considered... Figure 3 As shown. It should be noted that, although Figures 1 to 4 , Figure 6 and Figures 8 to 13 The diagram illustrates the assembly connection of a first buckle 10 to a first backpack strap 210 via a first through hole 15, and the assembly connection of a second buckle 20 to a second backpack strap 220 via a second through hole 22. Obviously, depending on actual needs, the assembly connection methods of the first buckle 10 and the first backpack strap 210, and the assembly connection methods of the second buckle 20 and the second backpack strap 220, can be other structures well-known in the art; therefore, they are not considered separately. Figures 1 to 4 , Figure 6 and Figures 8 to 13 The above is the limit.

[0040] Compared with the prior art, the design of "the first buckle body 10 is provided with a lateral sliding cavity 11 and a retractable spring lock assembly 30 partially exposed in the lateral sliding cavity 11, the lateral sliding cavity 11 respectively penetrates the adjacent first side surface 12 and the first end surface 13 of the first buckle body 10, the second buckle body 20 is provided with a side slider 21 that can slide into or out of the lateral sliding cavity 11 from the first side surface 12, the side slider 21 slides to the locking position of locking with the spring lock assembly 30 by pushing the spring lock assembly 30 inward during the process of sliding into the lateral sliding cavity 11, and the side slider 21 extends out of the first buckle body 10 from the first end surface 13 when in the locking position, and the first buckle body 10 prevents the side slider 21 from being pulled out of the lateral sliding cavity 11 in the direction in which the side slider 21 extends out of the first buckle body 10" makes the first backpack strap 210 more secure to the first buckle body 10. The pulling direction of the first buckle 10 and the pulling direction of the second backpack strap 220 on the second buckle 20 are intersecting with the unlocking direction (see the direction indicated by arrow A) (for example, but not limited to, perpendicular), thereby improving the reliability of the first buckle 10 and the second buckle 20 fastening. On the other hand, during the unlocking operation, the operator only needs to hold the first buckle 10 with one hand and the second buckle 20 with the other hand, and apply force to make the side slider 21 slide out of the lateral sliding cavity 11. Before sliding, the side slider 21 pushes the spring lock assembly 30 inward to release the spring lock assembly 30, and then slides out of the lateral sliding cavity 11 to achieve the purpose of separating the first buckle 10 and the second buckle 20. Therefore, the pin is eliminated, and there is no need to press the pin or other switches to unlock. It has the advantages of being convenient, quick and easy to use, and providing an excellent user experience.

[0041] It should be further noted that the hardware backpack buckle 100 of this utility model can be made of stainless steel or aluminum alloy, which has the advantages of being more robust and less prone to wear compared to plastics such as nylon. Furthermore, the first buckle body 10 and the second buckle body 20 and side slider 21, which together form an integrated structure, can be manufactured using Binder Jetting 3D printing technology, CNC machining, metal injection molding, and forging. Since Binder Jetting 3D printing technology uses a binder sprayed onto powder material to create a layer-by-layer model, it can quickly form a preform, eliminating the need for mold making and significantly saving time and improving development efficiency. In addition, the stainless steel metal powder selected has a particle size of less than 20 micrometers, low oxygen content, high density, low porosity, and high sphericity, exhibiting excellent flowability, superior oxidation resistance, and good molding performance for complex heterogeneous shapes, enabling the development of complex shapes that traditional CNC machining cannot achieve. Therefore, the hardware backpack buckle 100 of this utility model is advanced and innovative in the development of hardware supporting processes for high-end industrial bags.

[0042] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall fall within the scope of the present utility model.
