In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0026] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0027] Refer Figures 1 to 5 As shown, a sheet metal edge staple includes a plastic shell 1 and a buckle 2 installed in the plastic shell 1. An installation groove 11 for installing the buckle 2 is provided in the plastic shell 1. Both ends of the installation groove 11 penetrate through both ends of the plastic shell 1 respectively, and form an installation opening and a stop opening. The buckle 2 is slidably installed in the plastic shell 1 along the installation opening. Anti-retreat spring tongues 12 are respectively provided on both sides of the inner wall of the installation groove 11. A connecting boss protrudes from the outer wall of the plastic shell 1, and a number of connecting grooves 13 for installing tie straps are provided.

[0028] In this technical solution, the plastic shell is integrally formed by conventional processes such as injection molding, and an installation groove for installing the buckle is formed. The buckle is made of metal and is integrally formed by processes such as bending. The buckle is slidably installed in the installation groove of the plastic shell through the installation opening of the installation groove, without causing excessive extrusion deformation to the plastic shell, avoiding damage to the overall installation retention force of the sheet metal edge staple. The anti-retreat spring tongues limit the buckle from sliding out, and at the same time, the buckle can be disassembled from the plastic shell by拨动 the anti-retreat spring tongues, realizing the detachable installation of the buckle and facilitating the replacement of the buckle alone.

[0029] For example, see Figures 1 to 5 As shown, both the plastic shell and the buckle 2 are U-shaped or C-shaped structures.

[0030] In this technical solution, the plastic shell has a conventional structure such as U-shape or C-shape, and has a mounting groove for snap-fit ​​installation. The snap-fit ​​has a conventional structure such as U-shape or C-shape corresponding to the mounting groove. On the one hand, it is convenient to install in the mounting groove of the plastic shell, and on the other hand, it is convenient to snap onto the edge of the sheet metal part.

[0031] For example, see Figure 1 and Figure 2 As shown, the inner walls on both sides of the opening end of the mounting groove 11 are respectively provided with sliding grooves 14, and the buckle 2 is provided with locking feet 21 that slide in the sliding grooves 14 respectively.

[0032] In this technical solution, the slide groove is set along the length of the mounting groove and runs through both ends of the plastic shell. The clip's feet slide in the slide groove to achieve sliding installation of the clip, which will not cause excessive compression deformation to the plastic shell and avoid damage to the overall installation and holding force of the sheet metal edge clip.

[0033] For example, see Figures 1 to 5 As shown, the inner wall of the slide groove 14 and the mounting groove 11 are set at an angle.

[0034] In this technical solution, the inner walls of the sliding groove and the mounting groove, as well as the corresponding side walls of the clamp and the buckle, are set at an angle, providing sufficient space to increase the depth of the sliding groove, thereby increasing the contact area between the clamp and the sliding groove, providing sufficient limit for the buckle, and avoiding installation failure caused by the buckle and the plastic shell detaching.

[0035] For example, see Figure 3 and Figure 4 As shown, a limiting boss 15 protrudes from the inner wall of the mounting groove 11 near the stop port.

[0036] In this technical solution, a limiting boss protrudes from the top of the inner wall of the end of the mounting groove near the stop opening (the end opposite to the opening of the mounting groove), which is used to limit the installation position of the buckle and works with the anti-reverse spring to limit the buckle.

[0037] For example, see Figure 3 and Figure 4 As shown, the mounting slot 11 is provided with a clearance slot 16 corresponding to the anti-reverse spring 12.

[0038] In this technical solution, the side of the anti-reverse spring protruding from the inner wall of the mounting groove is a sloping structure. When the buckle is installed, the outer wall of the buckle presses against the sloping surface of the anti-reverse spring, and the corresponding part of the anti-reverse spring tilts and enters the clearance groove to avoid interfering with the installation of the buckle. After the buckle is installed in place, the anti-reverse spring resets and extends into the buckle's slot to prevent the buckle from slipping out.

[0039] For example, see Figures 1 to 4 As shown, the outer wall of the plastic shell 1 has several reinforcing ribs 17 protruding.

[0040] In this technical solution, the reinforcing ribs are used to improve the overall strength of the plastic shell, thereby reducing the possibility of deformation under stress, providing strong support for the buckle, and improving the overall installation and holding force of the sheet metal edge clips.

[0041] For example, see Figure 1 , Figure 2 and Figure 5 As shown, the buckle 2 is provided with a first-stage latch 21 and a second-stage latch 22.

[0042] In this technical solution, the first-stage and second-stage jaws respectively abut against both sides of the sheet metal, pressing against the sides of the sheet metal at multiple points and forming a clamping force, thereby improving the reliability between the jaws and the sheet metal parts.

[0043] For example, see Figure 5 As shown, the first-stage claw 21 and the second-stage claw 22 are staggered along the opening direction and length direction of the mounting groove 11.

[0044] In this technical solution, the first-level claws extend from the corresponding claw feet, and the second-level claws are punched out from the side wall of the buckle and bent. The gap between the second-level claws and the buckle in the width direction serves as a groove corresponding to the anti-reverse spring tongue, which does not require additional processing. The first-level claws and the second-level claws press against the side of the sheet metal at multiple points and form a clamping force, which improves the reliability between the claws and the sheet metal parts.

[0045] See Figure 6 and Figure 7 As shown, a sheet metal cable tie includes the aforementioned sheet metal edge clips and a cable tie 3 connected to the sheet metal edge clips.

[0046] In this technical solution, conventional cable ties can be used and inserted into the connecting groove. The connecting boss can be set on the top or side of the plastic shell according to actual use needs.

[0047] In summary, the sheet metal edge clip structure of this utility model is simple. The clip slides along one end of the mounting groove onto the plastic shell, which will not cause excessive compression and deformation to the plastic shell, thus avoiding damage to the overall installation and holding force of the sheet metal edge clip. The anti-reverse spring restricts the clip. At the same time, the clip can be separated from the plastic shell by moving the anti-reverse spring, realizing the detachable installation of the clip and facilitating the replacement of the clip individually.

[0048] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0049] The above description is only a specific embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
