[0024] The following detailed implementation provides a plurality of different embodiments or examples for implementing the utility model. Of course, these are only examples and are not intended to be limiting. In addition, repeated reference numbers and / or letters can be used in different embodiments. These repetitions are for the purpose of simply and clearly describing the utility model, and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0025] As Figures 1-6 ​The installation structure of the shown tube lamp spring clip includes a lamp shell 1 and spring clip assemblies arranged on both sides of the lamp shell 1. The spring clip assembly includes a fixed mounting plate 2 mounted on the lamp shell 1, a fixed pressing plate 4 rotatably mounted on the fixed mounting plate 2 through a pin 3, and a torsion spring 5 sleeved on the pin 3. The fixed mounting plate 2 includes a lower vertical plate 6, an intermediate transition plate 7, and an upper vertical plate 8 arranged in sequence. The upper vertical plate 8 is provided with a bending plate 9 bent outward on both sides. The pin 3 is arranged on the two bending plates 9. A lower limiting flange 10 and an upper limiting flange 11 are arranged on the outside of the lamp shell 1. The upper end of the lower limiting flange 10 is provided with a insertion slot 12 for the lower vertical plate 6. The upper vertical plate 8 is provided with an upper limiting elastic sheet 13 bent inward and extending upward and obliquely. When the lower vertical plate 6 is inserted into the insertion slot 12, the upper end of the upper limiting elastic sheet 13 abuts against the upper limiting flange 11, thereby limiting and fixing the lower vertical plate 6 in the insertion slot 12.

[0026] Firstly, the spring clip assembly needs to be pre-assembled before being assembled with the lamp shell 1.

[0027] When the spring clip assembly is pre-assembled, the pin 3 penetrates through the fixed pressing plate 4, the torsion spring 5, and the bending plates 9 on both sides of the upper vertical plate 8 of the fixed mounting plate 2, so that the fixed pressing plate 4 can rotate around the pin 3. The two ends of the torsion spring 5 abut against the fixed mounting plate 2 and the fixed pressing plate 4 respectively, thereby providing the fixed pressing plate 4 with continuous elastic force inwardly converging, and the pre-assembly of the spring clip assembly is completed.

[0028] When the spring clip assembly is assembled with the lamp shell, the fixed mounting plate 2 adopts a three-section integrated structure of the lower vertical plate 6, the intermediate transition plate 7, and the upper vertical plate 8. When assembling, the lower vertical plate 6 is aligned with the insertion slot 12 at the upper end of the lower limiting flange 10 on the outside of the lamp shell 1, and the lower vertical plate 6 is axially inserted into the insertion slot 12. When the lower vertical plate 6 is inserted to a preset position, the upper limiting elastic sheet 13 on the upper vertical plate 8 is bent inward and extends upward and obliquely, and the upper end thereof abuts against the upper limiting flange 11 on the outside of the lamp shell 1. The upper limiting elastic sheet 13 limits the lower vertical plate 6 from being reversely detached from the insertion slot 12, and the insertion slot 12 limits the lower vertical plate 6 laterally, thereby achieving bidirectional positioning and fixing of the fixed mounting plate 2 and the lamp shell 1, and finally completing the assembly of the spring clip assemblies on both sides and the lamp shell 1.

[0029] Therefore, the fixed mounting plate 2 is fixed by the structure of the lower vertical plate insertion and the upper limiting elastic sheet abutting, without additional fasteners such as screws. When assembling, the fixed mounting plate 2 can be fixed only by inserting the lower vertical plate 6, which can be quickly completed by one person without tools. Compared with the traditional screw fastening method, the assembly time is greatly shortened, and the production and installation efficiency is greatly improved.

[0030] Referring to Figure 2 , Figure 4 , Figure 6As shown, a square through hole 21 is arranged on the outside of the lower limiting flange 10 and communicates with the insertion slot 12, and a lower limiting elastic sheet 22 is arranged on the lower vertical plate 6 and is bent to the outside and extends upwardly and obliquely, and the upper end of the lower limiting elastic sheet 22 abuts against the square through hole 21.

[0031] Specifically, the lower vertical plate 6 of the fixed mounting plate 2 is inserted into the insertion slot 12 of the lower limiting flange 10 of the lamp shell 1, and when the lower vertical plate 6 moves downwardly, the lower limiting elastic sheet 22 is pressed and deformed inwardly due to the contact with the inner wall of the insertion slot 12, and an elastic restoring force is generated; when the lower vertical plate 6 is inserted to the preset position, two key limiting actions are completed synchronously: one is that the upper limiting elastic sheet 13 of the upper vertical plate 8 abuts against the upper limiting flange 11, and the upper axial limiting is realized; the other is that the lower limiting elastic sheet 22 moves to the square through hole 21 outside the lower limiting flange 10, and the lower limiting elastic sheet 22 is elastically reset due to the disappearance of the extrusion force of the inner wall of the insertion slot 12, and the upper end of the lower limiting elastic sheet 22 is clamped into and abuts against the square through hole 21, and the lower axial limiting is formed. At this time, the lateral limiting of the insertion slot 12 to the lower vertical plate 6, the upper axial limiting of the upper limiting elastic sheet 13, and the lower axial limiting of the lower limiting elastic sheet 22 and the square through hole 21 form a three-dimensional limiting structure, and the fixed mounting plate 2 is firmly locked on the lamp shell 1.

[0032] Preferably, a guide bevel 41 is arranged on the outside of the upper end of the upper limiting flange 11. Thus, when the lower vertical plate 6 is inserted into the insertion slot 12, the guide bevel 41 on the outside of the upper end of the upper limiting flange 11 contacts the upper limiting elastic sheet 13, and the guide bevel 41 forces the upper limiting elastic sheet 13 to elastically deform inwardly through the guiding effect of the bevel, and when the lower vertical plate 6 is inserted to the preset position, the upper limiting elastic sheet 13 passes the transition area of the guide bevel 41 and the upper limiting flange 11, and is elastically reset and abuts against the lower end surface of the upper limiting flange 11.

[0033] Thus, the guide bevel 41 provides a continuous transition guiding path, the upper limiting elastic sheet 13 smoothly slides along the bevel and gradually deforms, and the phenomenon of jamming and dead end of the traditional right-angle edge is avoided, and the assembly process is more smooth.

[0034] Preferably, the lower vertical plate 6, the intermediate transition plate 7, the upper vertical plate 8, the bent plate 9, the upper limiting elastic sheet 13 and the lower limiting elastic sheet 22 are integrally stamped and formed of metal material.

[0036] Referring to Figure 5 、 Figure 6 As shown in FIG. 8, a plurality of circular holes 31 are spaced apart upward and downward on the two bent plates 9, and the pin 3 is horizontally arranged in the corresponding circular holes 31.

[0037] The plurality of circular holes 31 spaced apart upward and downward provide multiple installation height options for the pin 3, the position of the fixed pressing plate 4 can be adjusted according to the installation holes of different thicknesses (such as the ceiling plate material with a thickness of 8-20 mm), various installation scenes are adapted, special spring clip assemblies do not need to be designed for different requirements, and the product universality is significantly improved. Before the spring clip assembly is pre-installed, according to the requirements of the down lamp installation scene, a corresponding group of the plurality of circular holes 31 spaced apart upward and downward on the two bent plates 9 is selected.
