Description

Technical Field

[0001] This utility model relates to the field of snap-fit ​​structures, specifically a snap-fit ​​structure. Background Technology

[0002] Employee badges typically include a card holder, an employee information card inserted into the card holder, and a lanyard for hanging the card holder around the employee's neck. To improve the ease of wearing the badge, the lanyard usually has a buckle structure, allowing the badge to be worn not only over the head but also by wrapping the two ends of the lanyard around the neck and connecting them to the buckle.

[0003] However, existing name tag lanyard buckle structures typically prioritize the ease and sturdiness of the connection between the two clips, neglecting the safety of the name tag during use. Buckle structures where the connection is too rigid and cannot automatically detach under stress pose a risk of strangulation if the lanyard gets caught on an object, threatening the employee's life. Furthermore, the manufacturing process for existing buckle structures is complex, significantly increasing labor costs for companies with many employees. Therefore, existing name tag lanyard buckle structures cannot simultaneously address ease of connection, sturdiness, production costs, and safety during use.

[0004] The research objective of this utility model is to design a snap-on structure for employee badges that combines convenience, robustness, low cost, and security, in order to address the problems existing in the prior art. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a snap-fit ​​structure that can effectively solve the problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] A snap-fit ​​structure includes: a first snap-fit ​​member and a second snap-fit ​​member;

[0008] One end of the first snap-fit ​​component is configured as a plug-in portion, and one side of the plug-in portion protrudes and is folded and pinched together to form a snap-fit ​​portion;

[0009] The second snap-fit ​​component has an insertion area corresponding to the insertion part inside. One side of the first snap-fit ​​component has a snap-fit ​​hole that communicates with the insertion area and is adapted to the snap-fit ​​part. One end of the first snap-fit ​​component has a limiting part that is recessed towards the snap-fit ​​hole to expose one end of the insertion area. After the insertion part is inserted inward through one end of the insertion area, the snap-fit ​​part is first limited by the limiting part, pressed against the insertion part and pushed up by the limiting part. Then, after being released by the snap-fit ​​hole, it returns to the limiting position and passes through the snap-fit ​​hole.

[0010] Furthermore, the insertion part includes a snap-fit ​​layer. The front part of the snap-fit ​​layer arcs and then extends forward to form a contraction area with a width smaller than the width of the insertion area. The snap-fit ​​part is disposed in the contraction area and extends to the left and right and protrudes upward. The front end of the snap-fit ​​layer extends and folds over to the bottom of the snap-fit ​​layer to form a reinforcing layer.

[0011] Furthermore, the first snap-fit ​​component also includes a connecting portion connecting to the rear end of the snap-fit ​​layer. The left and right sides of the connecting portion extend in opposite directions and are folded towards each other to be fixed parallel to the bottom of the connecting portion to form a first fixing layer. The connecting portion and the two first fixing layers are used to fix the corresponding connecting structure.

[0012] Furthermore, the second snap-fit ​​component includes a support layer, one side of the support layer extending upward and folding to form a limiting layer parallel to the top of the support layer, the limiting portion and the snap-fit ​​hole are both provided on the limiting layer, the insertion area is formed between the limiting layer and the support layer, the other side of the limiting layer extending downward and folding to form a second fixing layer parallel to the bottom of the support layer, the support layer and the second fixing layer are used to fix the corresponding connection structure.

[0013] Furthermore, the height of the insertion area is greater than the thickness of the insertion part and less than the height of the snap-fit ​​part, and the width of the snap-fit ​​hole is adapted to the height of the snap-fit ​​part.

[0014] Furthermore, both the first and second snap-fit ​​components are made of cardboard, and one side of the insertion part protrudes and is folded and pinched together to form a snap-fit ​​part by being fixed with adhesive.

[0015] Therefore, the beneficial effects of this utility model are:

[0016] 1. The protrusion and folding action ensure the snap-fit ​​part remains upright. Under certain pressure, it can adaptively sway towards the insertion part and move closer. After the pressure is removed, it returns to its upright position. Based on this, the second snap-fit ​​part's limiting part and limiting hole allow the insertion part to be inserted into the insertion area. The snap-fit ​​part is first limited by the limiting part, pressed towards the insertion part, and lifted by the limiting part. Then, after being released by the snap-fit ​​hole, it returns to its original position and passes through the snap-fit ​​hole, thus completing the snap-fit ​​between the first and second snap-fit ​​parts. The snap-fit ​​part remains upright and inserted into the snap-fit ​​hole, maintaining the stability of the connection between the first and second snap-fit ​​parts and achieving both convenience and firmness in the connection. Furthermore, after the first and second snap-fit ​​components are applied to the connection structure of the name tag connecting rope and snap-fitted together, when the connecting rope is hooked and tightened by an external object and the insertion part moves in the direction of disengaging from the insertion area, the snap-fit ​​part will be pressed against the insertion part and push up the limiting part before disengaging from the insertion area, thereby completing the automatic separation between the first and second snap-fit ​​components. This can avoid the risk of the connecting rope strangling the neck and threatening the life safety of employees, and improve the safety of the buckle structure during use. At the same time, this design can also improve the convenience of separating the first and second snap-fit ​​components and improve the convenience of putting on and taking off the name tag.

[0017] 2. By reducing the width of the front end of the insertion part and the snap-fit ​​part, the ease of insertion of the insertion part into the insertion area is improved. The snap-fit ​​part is mainly pressed down and lifted by the middle of the limiting part, so as to avoid the snap-fit ​​part being unable to lift the limiting part due to an over-fitting width with the insertion area, which would cause the snap-fit ​​part to be over-pressed and unable to reset, or the insertion part to be difficult to be fully inserted into the insertion area. On this basis, in order to improve the structural strength of the insertion part, the front end of the snap-fit ​​layer is extended and folded to the bottom of the snap-fit ​​layer to form a reinforcing layer. Thus, by setting the insertion part as a double-layer structure including the snap-fit ​​layer and the reinforcing layer, the structural strength is improved, but the production cost of the first snap-fit ​​part is not excessively increased. It is only necessary to reserve the length of the reinforcing layer when cutting the cardboard and fold it to the bottom of the insertion part and fix it with hot melt glue. Specifically, the lower ends of the snap-fit ​​parts and the snap-fit ​​parts and the reinforcing layer are also fixed with hot melt glue.

[0018] 3. By adding the connecting part and the first fixing layer, the snap-fit ​​structure only needs to reserve two first fixing layers when cutting the cardboard. One end of the connecting structure can be fixed between the connecting part and the two first fixing layers by hot melt adhesive, which reduces the connection cost between the connecting structure and the first snap-fit ​​component, thereby reducing the overall production cost of the snap-fit ​​structure.

[0019] 4. By designing the second snap-fit ​​component as a three-layer structure consisting of a folded cardboard sheet, a support layer, a limiting layer, and a second fixing layer, the number of connection and fixing parts required for the second snap-fit ​​component is reduced. Furthermore, the other end of the connecting structure can be directly fixed between the support layer and the second fixing layer using hot melt adhesive, thereby reducing the molding cost of the second snap-fit ​​component and the connection cost between the connecting structure and the second snap-fit ​​component, and thus reducing the overall production cost of the snap-fit ​​structure.

[0020] 5. The height of the insertion area is greater than the thickness of the insertion part but less than the height of the snap-fit ​​part, and the width of the snap-fit ​​hole is adapted to the height of the snap-fit ​​part. This ensures that the height of the insertion area, while allowing the snap-fit ​​part and insertion part to pass under pressure, prevents the snap-fit ​​part from easily disengaging from the snap-fit ​​hole when the first and second snap-fit ​​parts are subjected to opposite forces. Furthermore, the width of the snap-fit ​​hole ensures that the snap-fit ​​part can be smoothly released and reset to its limit position within the snap-fit ​​hole, improving the success rate and stability of the engagement between the snap-fit ​​part and the snap-fit ​​hole.

[0026] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0027] refer to Figure 1-5 A snap-fit ​​structure includes: a first snap-fit ​​component 1 and a second snap-fit ​​component 2. Specifically, the connecting structure 3 is the connecting rope of the work badge. In order to reduce costs, both the first snap-fit ​​component 1 and the second snap-fit ​​component 2 are made of cardboard. In order to improve the structural strength of the first snap-fit ​​component 1 and the second snap-fit ​​component 2, the cardboard can be 280G black cardboard.

[0028] One end of the first snap-fit ​​component 1 is provided as a plug-in part 11. One side of the plug-in part 11 protrudes and is folded and pinched together to form a snap-fit ​​part 12. Specifically, in order to reduce costs, the plug-in part 11 can be fixed by hot melt adhesive or other adhesives after one side protrudes and is folded and pinched together to form a snap-fit ​​part 12.

[0029] The second snap-fit ​​member 2 has an insertion area 21 corresponding to the insertion part 11 inside. The first snap-fit ​​member 1 has a snap-fit ​​hole 231 through one side that communicates with the insertion area 21 and is adapted to the snap-fit ​​part 12. One end of the first snap-fit ​​member 1 is recessed in the direction close to the snap-fit ​​hole 231 to expose one end of the insertion area 21. After the insertion part 11 is inserted into the insertion area 21, the snap-fit ​​part 12 is first limited by the limiting part 232 and pressed against the insertion part 11 and pushes up the limiting part 232. Then, after being released by the snap-fit ​​hole 231, it is reset to the limiting position and inserted into the snap-fit ​​hole 231.

[0030] The above-described structure, through protrusion and folding for fixation, allows the snap-fit ​​part 12 to remain upright. Under certain blocking pressure, it can adaptively sway towards the insertion part 11 for compression, and return to its upright state after the blocking pressure disappears. Furthermore, the setting of the limiting part 232 and limiting hole of the second snap-fit ​​member 2 ensures that after the insertion part 11 is inserted into the insertion area 21, the snap-fit ​​part 12 is first limited by the limiting part 232, pressing against the insertion part 11 and lifting the limiting part 232. Then, after being released by the snap-fit ​​hole 231, it returns to its original position, passing through the snap-fit ​​hole 231, thus completing the snap-fit ​​between the first snap-fit ​​member 1 and the second snap-fit ​​member 2. The snap-fit ​​part 12 remaining upright and inserted into the snap-fit ​​hole 231 maintains the stability of the connection between the first snap-fit ​​member 1 and the second snap-fit ​​member 2, achieving both convenience and firmness in the connection. Furthermore, after the first snap fastener 1 and the second snap fastener 2 are applied to the connecting structure 3 of the name tag connecting rope and snapped together, when the connecting rope is hooked and tightened by an external object and the insertion part 11 moves in the direction of disengaging from the insertion area 21, the snap fastener 12 will be pressed against the insertion part 11 and push up the limiting part 232 before disengaging from the insertion area 21, thereby completing the automatic separation between the first snap fastener 1 and the second snap fastener 2. This can avoid the risk of the connecting rope strangling the neck and threatening the life safety of employees, and improve the safety of the buckle structure when in use. At the same time, this design can also improve the convenience of separation between the first snap fastener 1 and the second snap fastener 2, and improve the convenience of putting on and taking off the name tag.

[0031] To improve the success rate of the insertion of the connector 11 into the insertion area 21, the connector 11 includes a snap-fit ​​layer 111. The front part of the snap-fit ​​layer 111 arcs and extends forward to form a contraction area 1111 with a width smaller than that of the insertion area 21. The snap-fit ​​part 12 is disposed in the contraction area 1111 and extends to the left and right and protrudes upward. By reducing the width of the front end of the connector 11 and the snap-fit ​​part 12, the ease of insertion of the connector 11 into the insertion area 21 is improved. Furthermore, the snap-fit ​​part 12 is mainly pressed down and mainly pushed up by the middle of the limiting part 232, so as to avoid the snap-fit ​​part 11 being unable to push up the limiting part 232 due to the width of the snap-fit ​​part 12 being too mismatched with the width of the insertion area 21, thus preventing the snap-fit ​​part 11 from being unable to push up the limiting part 232. 2. If the pressure is too high and the device cannot be reset, or if the insertion part 11 is difficult to be fully inserted into the insertion area 21, in order to improve the structural strength of the insertion part 11, the front end of the snap-fit ​​layer 111 is extended and folded to the bottom of the snap-fit ​​layer 111 to form a reinforcing layer 112. Thus, by setting the insertion part 11 as a double-layer structure including the snap-fit ​​layer 111 and the reinforcing layer 112, the structural strength is improved, but the production cost of the first snap-fit ​​part 1 is not excessively increased. It is only necessary to reserve the length of the reinforcing layer 112 when producing and cutting the cardboard, fold it to the bottom of the insertion part 11, and then fix it with hot melt glue. Specifically, the lower ends of the snap-fit ​​parts 12 and the snap-fit ​​parts 12 and the reinforcing layer 112 are also fixed with hot melt glue.

[0032] To further reduce the production cost of the snap-fit ​​structure, the first snap-fit ​​component 1 also includes a connecting portion 13 connecting to the rear end of the snap-fit ​​layer 111. The left and right sides of the connecting portion 13 extend in opposite directions and then fold towards each other to be fixed parallel to the bottom of the connecting portion 13, forming a first fixing layer 14. The connecting portion 13 and the two first fixing layers 14 are used to fix the corresponding connecting structure 3. Specifically, one end of the nameplate connecting rope is fixed between the connecting portion 13 and the two first fixing layers 14 by adhesive. Thus, by adding the connecting portion 13 and the first fixing layer 14, the snap-fit ​​structure only needs to reserve two first fixing layers 14 when cutting the cardboard, so that one end of the connecting structure 3 can be fixed between the connecting portion 13 and the two first fixing layers 14 by hot melt adhesive, reducing the connection cost between the connecting structure 3 and the first snap-fit ​​component 1, thereby reducing the overall production cost of the snap-fit ​​structure.

[0033] To further reduce the production cost of the snap-fit ​​structure, the second snap-fit ​​component 2 includes a support layer 22. One side of the support layer 22 extends upward and folds over to form a limiting layer 23 parallel to the top of the support layer 22. The limiting part 232 and the snap-fit ​​hole 231 are both provided on the limiting layer 23. The insertion area 21 is formed between the limiting layer 23 and the support layer 22. The other side of the limiting layer 23 extends downward and folds over to form a second fixing layer 24 parallel to the bottom of the support layer 22. The support layer 22 and the second fixing layer 24 are used to fix the corresponding connecting structure 3. Specifically, the other end of the name tag connecting rope is fixed between the support layer 22 and the second fixing layer 24 by means of adhesive. By designing the second snap-fit ​​2 as a three-layer structure consisting of a folded cardboard sheet, a support layer 22, a limiting layer 23, and a second fixing layer 24, the required connection and fixing parts for the second snap-fit ​​2 are reduced. Furthermore, the other end of the connecting structure 3 can be directly fixed between the support layer 22 and the second fixing layer 24 using hot melt adhesive. This reduces the molding cost of the second snap-fit ​​2 and the connection cost between the connecting structure 3 and the second snap-fit ​​2, thereby reducing the overall production cost of the snap-fit ​​structure.

[0034] To improve the stability of the latching part 12 when it is limited to passing through the latching hole 231, the height of the insertion area 21 is greater than the thickness of the insertion part 11 and less than the height of the latching part 12, and the width of the latching hole 231 is adapted to the height of the latching part 12. This ensures that the height of the insertion area 21 allows the latching part 12 and insertion part 11 to pass through under pressure, while preventing the latching part 12 from easily disengaging from the latching hole 231 when the first latching member 1 and the second latching member 2 are subjected to opposite forces. Furthermore, the width of the latching hole 231 ensures that the latching part 12 can be smoothly released and reset to its limited position within the latching hole 231, thus improving the success rate and stability of the engagement between the latching part 12 and the latching hole 231.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
