Description

Technical Field

[0001] This utility model belongs to the field of protective box technology, and in particular relates to a protective box for subway sensor data cables. Background Technology

[0002] With the rapid development of intelligent monitoring technology for rail transit, subway sensors, as the core component of tunnel structure safety monitoring, directly determine the reliability of the early warning system through the stability of their data transmission. As a key carrier of the "sensing-transmission" link, the sensor data line needs to be in the complex environment of subway tunnels, which is humid, corroded by chloride / sulfate ions, dust accumulation, and frequent vibrations. Therefore, high-performance subway sensor data line protection boxes are needed to protect them.

[0003] However, the existing protection boxes are not easy to disassemble and assemble quickly during use, resulting in low operational efficiency when maintaining and replacing subway sensor data cables, and making it difficult to carry out timely maintenance of the lines in the vibration environment of subway tunnels. Utility Model Content

[0004] The purpose of this utility model is to provide a protective box for subway sensor data cables. By setting up a quick-release part, it solves the problems of existing protective boxes being inconvenient to quickly disassemble and assemble during use, having low operational efficiency when maintaining and replacing subway sensor data cables, and being difficult to conduct timely maintenance of the line in the vibration environment of subway tunnels.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a protective box for subway sensor data cables, comprising two data cables and further comprising: a protective part disposed on the two data cables; two quick-release parts disposed on the two data cables; a guide part disposed on the data cables; each quick-release part includes a latching assembly disposed on the corresponding data cable; and a slot assembly disposed on the corresponding data cable. The latching assembly includes a U-shaped block disposed on the corresponding data cable, the bottom of which has two rectangular grooves. Several spring dampers are fixedly connected to the inner walls of the two rectangular grooves on their adjacent sides, and two locking blocks are fixedly connected to the opposite sides of the spring dampers. The outer walls of the two locking blocks are slidably connected to the inner walls of the two U-shaped blocks. Each U-shaped block has a push-button; the two locking blocks are mirror images of each other. Each push-button includes a button fixedly connected to the opposite side of the two locking blocks, and both buttons are slidably connected to the U-shaped block.

[0007] Furthermore, the card slot assembly includes a U-shaped block two disposed at the bottom of the U-shaped block one, and two limiting card slots are provided on the top of the U-shaped block two. The two limiting card slots are respectively adapted to the two card blocks, and the protruding parts of the two card blocks are respectively locked in the two limiting card slots. The inner wall of the U-shaped block two is fixedly connected to the protective shell located on the lower side.

[0008] Furthermore, the protective part includes two protective shells disposed on the data lines. The outer wall of the upper protective shell is fixedly connected to the U-shaped block, and connectors are provided on the two data lines; the two data lines are connected through the connectors.

[0009] Furthermore, the guide portion includes a guide assembly mounted on two protective shells; a sealing assembly disposed on the two protective shells; the guide assembly includes several guide rods fixedly connected to the top of the lower protective shell, and several guide grooves opened at the bottom of the upper protective shell; the several guide rods are respectively inserted into the several guide grooves and contact the inner wall.

[0010] Furthermore, the sealing assembly includes two U-shaped sealing blocks fixedly connected to the top of the lower protective shell, and two arc-shaped sealing blocks fixedly connected to each of the two protective shells; the tops of the two U-shaped sealing blocks contact the upper protective shell, and several arc-shaped sealing blocks abut against two data lines passing through the two protective shells.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting up a quick-release assembly, during installation, the upper and lower protective shells are aligned. The U-shaped block one connected to the upper protective shell is pressed down with the protective shell. The locking block is squeezed by the limiting slot of the U-shaped block two, compressing the spring damper in the rectangular slot. When the locking block slides to the bottom of the limiting slot, the spring damper rebounds and pushes the locking block back to its original position. Its protruding part is locked into the limiting slot, thus fixing the U-shaped block one and U-shaped block two, thereby completing the splicing of the two protective shells. During disassembly, press the button on the outside of the locking block to move the locking block in the direction of compressing the spring damper, so that the locking block is disengaged from the limiting slot, and the two protective shells can be separated. Through the cooperation of the buckle assembly and the slot assembly, the protective box can be quickly disassembled and installed, which greatly improves the operational efficiency of maintenance and replacement of subway sensor data lines, so that the line can be inspected in a timely manner in the vibration environment of subway tunnels.

[0013] 2. By setting up a guide section, during the operation of the guide assembly, as the upper protective shell covers the lower protective shell, the guide rod at the top of the lower protective shell is precisely inserted into the guide groove at the bottom of the upper protective shell. Through the sliding contact between the guide rod and the guide groove, the two protective shells are guided to align and fit together. In the sealing assembly, the U-shaped sealing block of the lower protective shell fits together with the protective shell and makes tight contact with the bottom of the upper protective shell. At the same time, the arc-shaped sealing block abuts against the outer wall of the data cable passing through the protective shell to form a sealing structure. This ensures that the upper and lower protective shells are quickly aligned, avoiding misalignment during installation that could lead to sealing failure or the buckle not engaging properly. It also effectively isolates the humid gas, dust, and corrosive ions in the subway tunnel, preventing them from entering the protective box and corroding the data cable and connectors.

At this time, the locking block 214 is squeezed by the limiting locking groove 222 and moves towards the spring damper 213, compressing the spring damper 213, until the locking block 214 slides into the limiting locking groove. At the bottom of 222, the spring damper 213 rebounds and drives the locking block 214 to reset, so that its protruding part is locked into the limiting slot 222, thereby fixing the U-shaped block 1 211 and U-shaped block 221 together and completing the assembly of the two protective shells 112. When disassembling, press the button 215 to move the locking block 214 toward the spring damper 213 until the locking block 214 can slide out of the limiting slot 222, and then the upper protective shell 112 can be removed to complete the separation and disassembly of the two.
