[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0035] Example 1

[0036] Reference Figure 1 to Figure 4 , which is the first embodiment of the utility model, and this embodiment provides an edge fixing mechanism, which connects the edge of the card through the spring sheet, and then fastens the spring sheet through the clamping assembly 200, so as to achieve the effect of quick disassembly and assembly of the edge fixed object, and comprises a spring sheet and a clamping assembly 200 for fixing the spring sheet; the cross-sectional profile of the spring sheet is C-shaped, and the clamping assembly 200 comprises a cylindrical clamping seat 201, and slots 201a are provided at both ends of the clamping seat 201, and a first strip groove 201c is provided on the outer wall of the clamping seat 201 connected to the slot 201a, and a side of the clamping seat 201 away from the first strip groove 201c is provided A second strip groove 201e is provided, and the opening width of the second strip groove 201e is greater than the width of its bottom groove. The clamp seat 201 is located between the slots 201a, and a clamping strip 201f is provided at the bottom of the slot 201b. The clamp seat 201 is located on both sides of the slot 201a and has slots 201b, and the spring sheet is plugged into the slot 201a. The spring sheet is vertically bent and sleeved with the first strip groove 201c, and the spring sheet is sleeved with the clamping strip 201f. The spring sheet is located at the right-angle bend in the slot 201a, and the bends on both sides thereof protrude with sharp corners 101, and the sharp corners 101 match and sleeve with the slots 201b on both sides of the slot 201a.

[0037] The mechanism mainly provides a special clamping method, which utilizes a thin curved elastic metal strip (refer to Figure 3 , Figure 4 The characteristics of the middle spring piece) when bending are that the curvature of the bending part decreases and the width increases (reference Figure 3 , Figure 4The spring sheet is inserted into the slot 201a of the clamp seat 201 and then bent into the first strip groove 201c, so that the bent sharp corner 101 is inserted into the slots 201b on both sides of the slot 201a, which fixes the position and angle of the spring sheet relative to the clamp seat 201, thereby realizing the fixing of other objects by the spring sheet.

[0038] Obviously, to maintain the fixed connection between the spring sheet and the clamp seat 201, the spring sheet needs to be kept in a bent state. Figure 2 and Figure 3 A clamping strip 201f with an arc outer wall is designed in the first strip groove 201c of the clamp seat 201, and the C-shaped spring piece is pressed to engage with the top of the clamping strip 201f to fix the spring piece.

[0039] The above-mentioned snap-on connection method has the advantages of simple and convenient installation and disassembly operations, and the structure is simple, easy to obtain and low in cost. However, it can obviously only be used as a temporary fixing method, because the bend of the spring piece always has a tendency to rebound, causing the spring piece to return to a straight strip shape, which is not conducive to the stability of the fixation. Therefore, a limit block 202 is designed on the clamp seat 201 to further limit the spring piece. Please refer to Example 2 for details.

[0040] In summary, the mechanism fastens the spring piece through the clamping assembly 200, which can achieve the effect of rapid disassembly and assembly of the edge-wrapped fixed object. At the same time, the mechanism also has the advantages of convenient installation and disassembly, simple structure, easy availability and low cost.

[0041] Example 2

[0042] Reference Figure 2 to Figure 6 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a limit block 202 of the edging fixing mechanism. The limit block 202 cooperates with the clamp seat 201 to suppress the spring piece, so as to achieve the purpose of preventing the spring piece and the clamp seat 201 from falling off. It includes a clamping assembly 200 and a limit block 202. The bottom of the limit block 202 is square and the top is triangular, and side strips 202a100 are arranged on both sides of the bottom of the limit block 202. A rectangular hole 202b is penetrated through the bottom of the limit block 202 along its length direction, and the bottom edges of the two sides of the rectangular hole 202b penetrate the bottom of the limit block 202 to form a gap 202c. The bottom of the limit block 202 is located between the two gaps 202c, and a clamping block 202d is arranged along the width direction of the bottom surface of the limit block 202.

[0043] Specifically, the clamping seat 201 is provided with sliding grooves 201d on both sides of the first strip groove 201c in parallel, and the side strips 202a100 on both sides of the limit block 202 are matched and slidably connected with the sliding grooves 201d, and a gap is provided between the spring pieces. The clamping block 202d of the limit block 202 is arranged in a C shape, and the arc edges on both sides of the clamping block 202d are arranged as rounded corners. The C-shaped mouth of the clamping block 202d and the clamping strip 201f are sleeved between the spring pieces, the triangular top end of the limit block 202 is arranged as a rounded corner, and a through hole 202e is provided along the axial direction of the rounded corner at the top end of the limit block 202.

[0044] The limit block 202 of the mechanism has two main functions:

[0045] First, a lanyard or other object is connected through the through hole 202e on the limit block 202 for wearing the badge installed by the mechanism;

[0046] Secondly, the limit block 202 can slide along the clamping strip 201f and the surface of the spring piece through the side strip 202a100 and the slide groove 201d, and the clamping block 202d at the bottom is moved and squeezed between the spring pieces by sliding the limit block 202. At this time, the limit block 202 is restricted by the clamping block 202d at the end of the spring piece and cannot slide freely. At this time, the spring piece is also restricted by the fit and pressure of the limit block 202 and cannot bounce up and break away from the clamping strip 201f. The limit block 202 and the clamping strip 201f restrict each other to achieve a stable connection between the spring piece and the clamp seat 201.

[0047] Of course, when the spring sheet and the clamping strip 201f need to be separated, the limit block 202 also needs to slide away from the spring sheet, so the clamping block 202d needs to have elasticity. Then, by providing a rectangular groove at the bottom of the limit block 202 and a gap 202c between the rectangular groove and the clamping block 202d, the limit block 202 is located in the clamping block 202d area to form a thin-walled structure and have elasticity, so that when necessary, the clamping block 202d and the limit block 202 can be pushed away from the spring sheet by applying sufficient external force;

[0048] It should be noted that the above-mentioned pushing of the limit block 202 away from the spring sheet refers to pushing the limit block 202 to one end of the clamp seat 201 so that the spring sheet at the other end is released from restriction. Similarly, the two spring sheets can be released from restriction by the reverse operation, and the same operating logic is used when installing the spring sheets.

[0049] It should be noted that this mechanism is a lightweight product, and the friction design between the clamp 201, the limit block 202 and the spring can meet the usage requirements of normal magnetic cards 400, identity cards 500 and their usage scenarios. Extreme situations and violent use are not within the design range of this device.

[0050] The rest of the structure is the same as that of Example 1.

[0051] In summary, the mechanism can prevent the spring sheet and the clamp seat 201 from falling off by suppressing the spring sheet through the cooperation between the limit block 202 and the clamp seat 201 .

[0052] Example 3

[0053] Reference Figures 1 to 12 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides a badge that is easy to assemble, and solves the problem that the shell volume and weight of the existing combined badge of magnetic card 400 and identity card 500 are large and affect the wearing comfort. It includes the edge fixing mechanism in the above embodiment, and the frame 300. The frame 300 is arranged in a concave shape, and the cross-sectional profile of the frame 300 is C-shaped. The two ends of the frame 300 are matched and connected with the spring pieces. The magnetic card 400 and the work card are sleeved in the frame 300. The magnetic card 400 and the work card have the same size, and the magnetic card 400 and the work card are in close contact. One end of the magnetic card 400 and the work card is inserted into the second strip groove 201e. A rubber strip 301 is also arranged between the frame 300 and the magnetic card 400 and the work card, and the frame 300, the magnetic card 400, the work card and the rubber strip 301 are interference fit.

[0054] For the convenience of structural description, the device illustrates the frame 300 and the spring piece as two components. In fact, the frame 300 and the side strip 202a100 are made of metal in one piece, using copper alloy or stainless steel. The reference thickness of the magnetic card 400 is 1 mm, the reference thickness of the identity card 500 is 0.6 mm, and the reference wall thickness of the frame 300 is 0.4 mm. The spring piece is thinned by pressing the frame 300, and the reference thickness is 0.2 mm. The frame 300 needs to have sufficient thickness to maintain structural strength, and the spring piece is made by thinning, so that the spring piece has good elasticity and handling feel. It should be noted that the frame 300 is formed into a concave shape, and after the rubber strip 301 is inserted, it is directly adapted to the magnetic card 400 and the identity card 500. The initial state of the spring piece and the two ends of the frame 300 remain straight strips.

[0055] During assembly, the magnetic card 400 is attached to the identity card 500, and the edges are aligned, and the frame 300 is sleeved with the attached magnetic card 400 and identity card 500, and the spring parts at both ends of the frame 300 are plugged into the slots 201a of the clamp seat 201, and then the protruding part of the edge strip 202a100 is pressed to bend it to form a sharp corner 101 and engage it with the slot 201b, so that its end is engaged with the card strip 201f. During operation, the limit block 202 is moved to the side that has been installed or to be installed to avoid affecting the operation. After the spring piece is engaged, the limit block 202 is moved to the middle of the clamp seat 201, so that its bottom block 202d is engaged between the spring pieces.

[0056] The rest of the structure is the same as that of Example 2.

[0057] In summary, the border 300 of the badge is only composed of thin-walled metal and rubber strips 301. In addition to the advantages of being simple, easy to obtain and low in cost, it also has the advantage of less shielding area for the magnetic card 400 and the identity card 500 than the traditional plastic shell. It is thinner, simpler and more beautiful, and solves the problem that the existing badge combined with the magnetic card 400 and the identity card 500 has a large shell volume and a large weight that affects wearing comfort.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
