The urban rail transit signal equipment is installed on the inner side of the protective box 1, and a buffer structure is installed between the protective box 1 and the base 2. The buffer structure includes a plurality of evenly distributed buffer springs 4. In the urban rail transit environment, a large vibration will be generated when a vehicle passes by. The buffer structure can play a good protective role for the equipment inside the box, preventing the equipment in the box from being subjected to severe vibration, thereby better protecting the equipment components.

[0026] A wire entry hole 5 is provided at the bottom end of the protective box 1 for connecting cables to external equipment. A wire management structure is installed on the inner wall of the protective box 1. The wire management structure includes a plurality of wire management units 6. The plurality of wire management units 6 are evenly installed on the inner wall of the protective box 1 to store the cables of the equipment. Specifically, the wire management unit 6 includes a connecting component and a limit plate 63. The limit plate 63 is connected to the inner wall of the protective box 1 through the connecting component. Excess cables can be wrapped around the connecting component. The limit plate 63 is used to limit the cables, so that the cables are not easy to become loose, which is convenient for maintenance personnel to inspect.

[0027] Regarding the connection components, specifically, Figure 4 It is shown that the connecting assembly includes a fixed sliding rod 61 and a movable sliding sleeve 62. One end of the fixed sliding rod 61 is fixed on the inner wall of the protective box 1, and the movable sliding sleeve 62 is slidably connected to the outer side of the fixed sliding rod 61. Two limit plates 63 are provided, and the two limit plates 63 are coaxially fixed at both ends of the movable sliding sleeve 62. The movable sliding sleeve 62 can be pulled outward for winding, avoiding the inconvenience caused by the adjacent wire management unit 6 to the winding.

[0028] Among them, a tension spring 64 is installed between the fixed sliding rod 61 and the movable sliding sleeve 62. After the winding is stored, the tension spring 64 can be used to automatically restore the sliding sleeve 62 and the limit plate 63. Under the elastic action of the tension spring 64, it is not easy to cause excessive pulling of the cable to cause damage to the cable connector.

[0029] Among them, a partition 7 is arranged between two adjacent wire management units 6, and the partition 7 is fixed to the inner wall of the protection box 1. The partition 7 can further separate the two adjacent wire management units 6 so that the two adjacent wire management units 6 will not interfere with each other, and wire management is more convenient.

[0030] Among them, a plurality of storage boxes 8 are installed on the inner end surface of the base 2, and the plurality of storage boxes 8 are evenly distributed on the base 2 from top to bottom; maintenance tools and equipment-related replacement parts can be placed in the plurality of storage boxes 8 in a classified manner, so as to facilitate maintenance operations by maintenance personnel.

[0031] The working principle of the utility model is as follows: pull the limit plate 63 outwards to wind the excess cables of the equipment around the movable sleeve 62, and release the limit plate 63 after winding, so that the tension spring 64 automatically brings the sleeve 62 and the limit plate 63 to reset, and under the elastic action of the tension spring 64, it is not easy to cause excessive pulling of the cables to cause damage to the cable connector; the partition 7 can further separate the two adjacent cable management units 6, so that the adjacent cable management units 6 will not cause obstacles when the sleeve 62 and the limit plate 63 are reset, and the cable management is more convenient; the maintenance tools and equipment-related replacement parts are placed in multiple storage boxes 8 respectively, which is convenient for maintenance personnel to perform maintenance operations; during use, a large vibration will be generated when a vehicle passes by, and the provided buffer structure can play a good protective role for the equipment inside the box, avoiding severe vibration of the equipment in the box, thereby better protecting the equipment components.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
