[0018] 2. The utility model is provided with a double-layer arc-shaped connecting bridge structure. While ensuring the strength of the overall connecting structure, the elastic space between the layers makes it easier to be squeezed into the slot of the light strip. At the same time, the arc-shaped surface design on the two sides of the elastic connecting bridge conforms to the ergonomic design on the one hand, which is convenient for taking the transparent elastic light strip clip, and on the other hand, reduces the interference of the elastic connecting bridge on the light-emitting area of ​​the light strip below.

DETAILED DESCRIPTION

[0029] The following is further described in detail through specific implementation methods:

[0030] like Figure 3-8 As shown, this embodiment shows a light strip installation structure for a copper alloy guide rail for an elevator, including a copper alloy guide rail 100, a light strip 200 and a transparent elastic light strip clip 300; the copper alloy guide rail 100 includes a light strip groove 110 with a mountain-shaped cross section; the light strip groove 110 includes an L-shaped groove edge 111 arranged on both sides of the groove and a glue injection cavity 112 for injecting waterproof glue; the light strip 200 includes a convex arc top surface 210, and the light strip 200 is arranged at the bottom of the glue injection cavity 112. Specifically, the transparent elastic light strip clip 300 is made of a transparent elastic material, which can be a condensation polymer of a silicate inorganic polymer gel material: a type of silicone rubber; using its transparent properties, it can be ensured to have a certain light transmittance after installation.

[0031] In this embodiment, the transparent elastic light strip clamping piece 300 is detachably connected with the light strip 200 to abut against the light strip groove 110. In this embodiment, during actual installation, the light strip 200 is detachably fixed and abutted against the light strip groove 110 by using the transparent elastic light strip clamping piece 300.

[0032] In this embodiment, the transparent elastic light strip clamp 300 includes elastic support blocks 310 respectively arranged on both sides and an elastic connection bridge 320 fixedly arranged between the support blocks on both sides. The support blocks on both sides are mirror images of each other; the top of the support block matches the groove body formed by the L-shaped groove edge 111, and the two can be detachably contacted and connected; the bottom surface of the support block matches the arc-shaped top surface 210 of the light strip 200, and the two can be detachably contacted and connected. The bottom surface of the elastic connection bridge 320 matches the arc-shaped top surface 210 of the light strip 200, and the two can be detachably contacted and connected. Specifically, the top of the elastic support block 310 matches the L-shaped groove edge 111 to form a card slot contact connection; the bottom of the elastic support block 310 and the bottom of the elastic connection bridge 320 both match the arc-shaped top surface 210 of the light strip 200, thereby forming a more reliable abutment and fixation. In this embodiment, it is specifically manifested that the transparent elastic light strip clamp 300 stably and reliably abuts the light strip 200 against the bottom of the light strip groove 110.

[0033] Further description, in some embodiments, such as Figure 3 , Figure 6 As shown, the two side surfaces of the elastic connecting bridge 320 that are not connected to the support block include an arc surface 321 that is concavely arranged. Specifically, the arc surface 321 conforms to the ergonomic design, which is convenient for taking the transparent elastic light strip clip 300. At the same time, the design of the arc surface 321 effectively reduces the shielding area of ​​the transparent elastic light strip clip 300 for the lower light strip 200; further explanation, during actual installation, after the support blocks on both sides are squeezed and placed into the L-shaped groove edge 111, the transparent elastic light strip clip 300 is subjected to the reaction force of the arc-shaped top surface 210 of the two sides of the groove body and the bottom light strip 200, and is guided to deform toward the middle and vertically upward through the structure, and the support blocks on both sides generate a downward force under the action of the L-shaped groove edge 111, so that the light strip 200 is firmly abutted against the light strip groove 110.

[0034] Further description, in some embodiments, such as Figure 4-6 As shown, the elastic connection bridge 320 includes a first arc-shaped connection bridge 322 disposed at the top and a second arc-shaped connection bridge 323 disposed at the bottom, and an elastic space 324 is provided between the first arc-shaped connection bridge 322 and the second arc-shaped connection bridge 323. Figure 4-7As shown, the main body of the first arc-shaped connecting bridge 322 is in an arc shape with its top ends detachably contacting and connecting with the L-shaped groove edge 111. Further explanation, in other embodiments, the distance from the top surface to the bottom surface of the inner wall of the elastic space 324 is twice or more the thickness of the second arc-shaped connecting bridge 323. Specifically, the setting of the first arc-shaped connecting bridge 322 ensures the strength of the overall connection structure, and the elastic space 324 between it and the second arc-shaped connecting bridge 323 makes it easier for the transparent elastic light strip clip 300 to be squeezed into the light strip groove 110. During actual installation, after the support blocks on both sides are squeezed into the L-shaped groove edge 111, the support blocks on both sides are subjected to the force acting toward the middle on both sides of the groove body, and the second arc-shaped connecting bridge 323 is subjected to the upward force of the arc-shaped top surface 210 of the bottom light strip 200. The first arc-shaped connecting bridge 322 and the second arc-shaped connecting bridge 323 are guided by their structures to produce deformation toward the middle and vertically upward directions. Under the action of the L-shaped groove edge 111, the transparent elastic light strip clamp 300 generates a downward force, and the light strip 200 is firmly abutted in the light strip groove 110, which is convenient for the later injection of glue.

[0035] Further description, in some embodiments, such as Figure 3-4 As shown, the top edge of the support block is provided with rounded corners to facilitate the transparent elastic light strip clamping piece 300 to be placed into the light strip groove 110 .

[0036] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
