Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 5 As shown:

[0023] Embodiment 1: The utility model provides a cable quick-install junction box for rail transit, including: a junction box mechanism 1, including a junction box assembly 11, a limit assembly 12 slidably embedded in the junction box assembly 11, a group of support assemblies 13 with the limit assembly embedded in the junction box assembly 11, and a group of support assemblies 13 can support the limit assembly 12; a cable fixing mechanism 2, including a fixing assembly 21 embedded in the limit assembly 12, and a clamping assembly 22 installed on the fixing assembly 21.

[0024] Specifically, the junction box assembly 11 includes a junction box body 111, a sealed door 112 is hinged on the front side of the junction box body 111, a plurality of wire entry holes 113 are opened on the top and bottom of the junction box body 111, and the plurality of wire entry holes 113 are connected to the interior of the junction box body 111, and a group of T-shaped guide frames 114 are fixedly connected to the inner side wall of the junction box body 111, and a plurality of limit holes 115 are opened longitudinally on the group of T-shaped guide frames 114.

[0025] Specifically, the limiting assembly 12 includes a support frame 121, both ends of which are provided with T-slots 122, the T-slots 122 and the T-shaped guide frames 114 match each other, the support frame 121 is slidably embedded between a group of T-shaped guide frames 114 through the T-slots 122, the front side of the support frame 121 is fixedly connected to one end of a group of limiting rods 123, the other end of a group of limiting rods 123 is fixedly connected to a limiting ring 124, the outside of a group of limiting rods 123 is slidably connected to a limiting plate 125, the outside of the limiting rods 123 and located between the limiting ring 124 and the limiting plate 125 is provided with a first spring 126, the first spring 126 can drive the limiting plate 125 to limit the fixing assembly 21.

[0026] Specifically, a group of support components 13 includes a support plate 131, the bottom of the support plate 131 is fixedly connected with a stop block 132, one end of the support plate 131 is embedded in the limiting hole 115, and the other end of the support plate 131 is used to support the support frame 121, and one side of the stop block 132 is against the T-shaped guide frame 114.

[0027] As can be seen from the above, when in use, the limiting plate 125 is pulled to make the first spring 126 in a compressed state, and then the fixing component 21 is placed on the support frame 121. After the placement is completed, the limiting plate 125 is released, and the first spring 126 recovers its deformation and pushes the limiting plate 125 to clamp and fix the fixing component 21. The cable is passed through the upper wire entry hole 113, and then through the fixing component 21 and the limiting component 12. The cable can be fixed by the cooperation of the clamping component 22 and the fixing component 21. When it is necessary to adjust the position of the fixing component 21 in the junction box body 111, the two support plates 131 are taken out from the limiting hole 115. At this time, the support plate 131 no longer supports the support frame 121, and the clamping assembly 22 is pushed to release the fixation of the cable, and then the support frame 121 is moved upward or downward. The support frame 121 moves stably along the T-shaped guide frame 114, and the two support plates 131 are inserted into the limiting holes 115 at a suitable height. The block 132 is against the T-shaped guide frame 114. At this time, the support frame 121 can be moved to the two support assemblies 13, and the support frame 121 and the fixing assembly 21 are supported by the two support assemblies 13, so as to facilitate the adjustment of the position of the fixing assembly 21 in the junction box body 111 for maintenance personnel to facilitate inspection.

[0028] Embodiment 2: This embodiment is basically the same as the previous embodiment, with the difference that the fixing assembly 21 includes a fixing block 211 located at the top of the support frame 121, a plurality of fixing holes 212 are formed through the fixing block 211, a receiving groove 213 is formed inside the fixing hole 212, a plurality of guide rods 214 are fixedly connected on the fixing block 211 and located in the receiving groove 213, and a second spring 215 is sleeved on the outside of the plurality of guide rods 214, which can drive the clamping assembly 22 to move toward the direction close to the fixing hole 212.

[0029] Specifically, the clamping assembly 22 includes a slider 221 slidably connected to the outside of the guide rod 214, one end of a group of connecting rods 222 is fixedly connected to the slider 221, the other end of the group of connecting rods 222 is commonly fixedly connected to a pressing plate 223, and one end of a plurality of connecting columns 224 is also fixedly connected to the slider 221, and the other ends of the plurality of connecting columns 224 are all fixedly connected to an arc-shaped clamping block 225.

[0030] As can be seen from the above, the pressing plate 223 is pushed, and the pressing plate 223 drives the slider 221 on the connecting rod 222 to slide in the storage groove 213 along the guide rod 214. At this time, the second spring 215 is in a compressed state, and the slider 221 drives the arc-shaped clamping block 225 on the connecting column 224 away from the fixing hole 212. At this time, the cable is passed through the fixing hole 212 and the pressing plate 223 is released. The second spring 215 restores its deformation and pushes the slider 221 to make the arc-shaped clamping block 225 on the connecting column 224 move in the direction close to the fixing hole 212, thereby fixing the cable between the arc-shaped clamping block 225 and the fixing hole 212.
