DETAILED DESCRIPTION

[0041] The utility model is further described below in conjunction with the accompanying drawings.

[0042] A staggered snap-in structure for a semi-hidden fixed handle, such as Figure 1-2 and Figure 6-7 As shown, the handle shell 1 and the decorative shell 2 are included. The handle shell 1 is provided with a handle groove 1b. The decorative shell 2 is fixedly connected to the handle groove 1b by a snap-fit ​​structure. The snap-fit ​​structure includes two lock buckles 21 and two groups of spring buckle groups that are locked with the lock buckles 21. The lock buckle 21 is integrally arranged on the side of the decorative shell 2 facing the handle groove 1b. The lock buckle 21 includes a locking plate 211, a first locking block 212 and a second locking block 213 that are arranged on both sides of the locking plate 211 and are staggered. The spring buckle group includes a first spring buckle 11 and a second spring buckle 12. The buckle 12 is integrally arranged on the handle housing 1, and the lock buckle 21 is correspondingly locked with the first spring buckle 11 and the second spring buckle 12 through the first locking block 212 and the second locking block 213; the first locking block 212 and the second locking block 213 are relatively staggered on both sides of the lock plate 211, so that the cross-section of the lock buckle 21 is Z-shaped. In this embodiment, the structural design of the Z-shaped lock buckle 21 is correspondingly arranged on the hypotenuse of the decorative shell 2, which facilitates the installation direction of the hypotenuse of the decorative shell 2 on the handle housing 1, thereby improving the locking firmness of the hypotenuse of the decorative shell 2 on the handle housing 1.

[0043] like Figure 2 , Figure 7 and Fig.12 As shown, the first spring buckle 11 and the second spring buckle 12 both include an elastic support sheet 111 and a latching protrusion 112 fixed on the side wall of the elastic support sheet 111. The first spring buckle 11 and the second spring buckle 12 are locked and matched with the locking portions 214 of the corresponding first locking blocks 212 and the second locking blocks 213 through the latching protrusion 112. When the decorative shell 2 is pressed and assembled onto the handle shell 1, the elastic support sheet 111 is elastically deformed, so that the first spring buckle 11 and the second spring buckle 12 are relatively stretched outward from a static state under the action of a huge pressing force. When the latching protrusions 112 of the first locking blocks 212 and the second locking blocks 213 pass over the latching protrusions 112 of the first spring buckle 11 and the second spring buckle 12, the elastic support sheet 111 restores its deformation by its own elastic force, so that the first spring buckle 11 and the second spring buckle 12 automatically approach and return to a static state, and at the same time, the corresponding latching protrusions 112 are locked and fixed with the locking portions 214.

[0044] like Figure 2 , Figure 6-7 and Figure 9-11 As shown, the first locking block 212 and the second locking block 213 both include a locking portion 214 integrally fixed on the locking plate 211, and a reinforcing connecting rib 215 is provided between the locking portion 214 and the locking plate 211. The first locking block 212 and the second locking block 213 are locked and matched with the corresponding first spring buckle 11 and the second spring buckle 12 through the locking portion 214. The addition of the reinforcing connecting rib 215 can enhance the strength of the connection structure between the first locking block 212, the second locking block 213 and the locking plate 211, thereby effectively improving the connection firmness between the decorative shell 2 and the handle body; the corresponding locking portions 214 of the first locking block 212 and the second locking block 213 are relatively arranged outwardly, and the corresponding locking portions 214 of the card protrusions 112 of the first spring buckle 11 and the second spring buckle 12 are relatively arranged inwardly, so that the lock buckle 21 can be locked with the corresponding first locking block 212 and the second locking block 213 through the first locking block 212 and the second locking block 213. The corresponding first spring buckle 11 and second spring buckle 12 are locked and fixed, so that each pair of lock buckles 21 and spring buckle groups can achieve the effect of locking and positioning in both the upper and lower directions, which greatly improves the locking firmness between the decorative shell 2 and the handle shell 1; the locking portion 214 is provided with a guiding inclined surface 214a corresponding to the card protrusion 112, and the locking portion 214 is guided and plugged with the corresponding card protrusion 112 through the guiding inclined surface 214a. The addition of the guiding inclined surface 214a enables the locking portion 214 of the first locking block 212 and the second locking block 213 to pass through the guiding inclined surface 214a more smoothly when the decorative shell 2 is pressed and assembled to the handle shell 1, thereby realizing the locking and fixing between the lock buckle 21 and the spring buckle group, thereby improving the installation convenience of the decorative shell 2 on the handle shell 1.

[0045] like Figure 3-5and Figure 8-11 As shown, a limiting structure is provided between the decorative shell 2 and the handle shell 1. When the decorative shell 2 is fixedly connected to the handle shell 1 by the snap-fit ​​structure, the decorative shell 2 is limited and stopped by the handle shell 1 through the limiting structure. The limiting structure can effectively prevent the decorative shell 2 from being damaged by excessive pressing on the handle shell 1. The limiting structure includes a positioning block 22 and an abutting block 13. The positioning block 22 is integrally provided on the decorative shell 2. The abutting block 13 corresponds to the positioning block 22 which is integrally provided on the handle shell 1. The positioning block 22 cooperates with the abutting block 13 to limit and stop. When the decorative shell 2 is installed in place on the handle shell 1, the stopping effect of the positioning block 22 and the abutting block 13 can prevent the decorative shell 2 from being excessively pressed on the handle shell 1. The decorative shell 2 is provided with a plurality of buckles 23 around it, and the handle shell 1 is provided with a plurality of clamping parts 14 corresponding to the buckles 23. The buckles 23 are clamped and positioned with the corresponding clamping parts 14. The two clamping matching modes of the buckles 23 and the clamping parts 14 and the lock buckle 21 and the spring buckle group can further improve the locking firmness between the decorative shell 2 and the handle shell 1; the decorative shell 2 is provided with a plurality of positioning blocks 24, and the handle shell 1 is provided with a plurality of positioning holes 1a corresponding to the positioning blocks 24. The positioning blocks 24 are plugged and positioned with the corresponding positioning holes 1a. The guiding matching between the positioning blocks 24 and the positioning holes 1a allows the lock buckle 21 and the spring buckle group to be guided and plugged, thereby improving the installation accuracy of the decorative shell 2 on the handle shell 1.

[0046] The basic working principle of the utility model is: during assembly, the decorative shell 2 is aligned with the pre-installation position of the handle groove 1b so that the lock buckle 21 is aligned with the spring buckle group, and then the decorative shell 2 is pressed toward the handle shell 1, so that one end of the lock buckle 21 is locked and fixed with the first spring buckle 11 through the first locking block 212, and the other end of the lock buckle 21 is locked and fixed with the second lock buckle 21 through the second locking block 213. Since the first locking block 212 and the second locking block 213 are relatively staggered on both sides of the locking plate 211, the decorative shell 2 can be staggered and locked with the spring buckle group on the handle shell 1 through the lock buckle 21. Through the locking cooperation of multiple pairs of lock buckles 21 and the spring buckle group, the decorative shell 2 can be kept locked with the handle shell 1 in multiple directions. Different from the situation in the market where a single locking direction makes the locking not firm, the utility model utilizes the staggered locking method, which can greatly improve the locking stability between the decorative shell 2 and the handle shell 1, and has the effect of firm locking and strong shock resistance.

[0047] The above description is only a preferred embodiment of the present utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the present utility model patent application are included in the scope of the present utility model patent application.
