[0044] Please refer to Figures 1 to 15As shown, the embodiment of the utility model provides a track system 100, including track 200 and module assembly 300. Track 200 is installed to installation base, and module assembly 300 is clamped and installed on track 200. Module assembly 300 can be lamps and lanterns, camera, electrical fittings, sensor and controller etc., not limited here. Track 200 can be composed of a track 200, and can be composed of multiple tracks 200 spliced.

[0046] In some other embodiments, multiple module assemblies 300 are installed on track 200, which can be spaced or adjacent.

[0047] As shown in Figures 1 to 5 As shown, in the embodiment, the track system 100 is composed of two spliced tracks 200, and one module assembly 300 is installed on each track 200. And the two module assemblies 300 are adjacent to each other at the splicing place of the two tracks 200. The longitudinal direction is defined as the length extension direction of the track 200, and the waterproof end cover 400 is arranged on the second end 2009 of the track 200 in the longitudinal direction, and the waterproof end cover 400 is sealingly connected with the track 200 and the module assembly 300.

[0048] Specifically, the waterproof end cover 400 is provided with a wire passing plug 4001 and a sealing block 4002. The wire passing plug 4001 is used to guide and fix the wire in the track system 100.

The track joint sealing assembly 2006 includes a track joint sealing plate 2061 and a track joint sealing member 2062. The track joint sealing plate 2061 is clamped with the track 200, and the track joint sealing member 2062 is clamped between the track joint sealing plate 2061 and the track 200. The track joint sealing member 2062 is made of a flexible waterproof material. The track joint sealing member 2062 is provided with a first matching portion 2621 which is matched with the shape of the first clamping portion 2004, so that the track joint sealing member 2062 and the track 200 are tightly fitted. By extruding the track joint sealing member 2062 outward by the track 200, the track joint sealing plate 2061 extrudes the track joint sealing member 2062 inward, achieving waterproof sealing of the track 200 at the joint.

[0052] A sealing plate limiting member 2611 is arranged at the bottom of the track joint sealing plate 2061, which is clamped with the track 200 to fix the track joint sealing plate 2061 and the track 200.

[0053] In the embodiment, the sealing plate limiting member 2611 includes a first limiting arm and a second limiting arm connected in sequence. The first limiting arm extends horizontally inward from the side of the track joint sealing plate 2061, and the second limiting arm extends vertically upward from the first limiting arm. The first limiting arm abuts against the first arm 2051, and the second limiting arm abuts against the second arm 2052, achieving clamping and fixing between the sealing plate limiting member 2611 and the track 200.

[0054] Referring to Figure 10As shown, a connecting plate 2008 is further arranged between the two rails 200, and the two rails 200 are connected through the connecting plate 2008. The overall shape of the connecting plate 2008 matches the rail shell 2001, facilitating installation on the rail shell 2001. The connecting plate 2008 is installed on the inner side of the rail shell 2001 and abuts against the bottom plate of the rail shell 2001. The bottom plate of the rail shell 2001 faces the installation base. Further, the connecting plate 2008 is provided with a second matching part 2081 which matches the shape of the first clamping part 2004, facilitating quick assembly of the connecting plate 2008 to the rail 200.

[0055] The connecting plate 2008 is arranged on the inner side of the rail 200 and covers the spliced joint on the inner side of the two rails 200, achieving waterproofing on the inner side of the spliced joint. Specifically, the connecting plate 2008 is provided with a connecting bracket 2007 which is located at the spliced joint of the two rails 200. Further, the connecting bracket 2007 abuts against the side of the third arm 2053 of the rail shell 2001 which faces the bottom plate. The connecting bracket 2007 is sleeved with a third sealing member 2071 which is located at the spliced joint of the two adjacent rails 200. The third sealing member 2071 is an annular sealing ring. The annular sealing ring is pressed against the spliced joint of the two rails 200 and abuts against the third arm 2053 of the rail shell 2001. The third sealing member 2071 is in interference fit with the two rails 200. That is, the connecting bracket 2007 presses the third sealing member 2071 downward, and the third arm 2053 of the rail 200 presses the third sealing member 2071 upward, so as to achieve sealing and waterproofing of the spliced joint of the rail 200. In this way, water is prevented from entering the rail 200 from the inner side of the spliced joint. The connecting plate 2008 and the rail spliced sealing assembly 2006 cooperate at the spliced joint, achieving double waterproofing protection.

[0056] Preferably, a protruding rib is arranged on the side of the third sealing member 2071 which faces the third arm 2053, so as to increase the friction between the third arm 2053 and the third sealing member 2071 and further improve the sealing performance of the inner side of the rail 200 at the spliced joint, preventing water from entering the rail 200 from the spliced joint.
