[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0030] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a measuring device for urban rail transit signal equipment, comprising a slider 6, a fixed block 5 is fixedly connected to the left side of the slider 6, a fixed shaft 11 is fixedly connected to the upper and lower sides of the fixed block 5, a rotating shell 4 is rotatably connected to the fixed shaft 11, a sliding shaft 10 is fixedly connected to the rotating shell 4, a storage plate 2 is rotatably connected to the upper and lower sides of the sliding shaft 10, a rotating shaft 1 is fixedly connected between the two storage plates 2, a measuring ruler 7 is rotatably connected to the outside of the two rotating shafts 1, and a lighting auxiliary component is installed inside the slider 6, and the lighting auxiliary component is used to provide lighting for the device at night. The outer side of the measuring ruler 7 is slidably connected to the inside of the slider 6, and the outer side of the measuring ruler 7 is slidably connected to the inside of the fixed block 5. A switch frame 3 is rotatably connected between the two rotating shells 4. The outer side of the measuring ruler 7 runs through the inside of the two storage plates 2. The outer side of the measuring ruler 7 is set between the two rotating shells 4.

[0031] Specifically, when using the measuring device, open the switch frame 3. The switch frame 3 can control the device to prevent the rotating shell 4 from moving during use, which is convenient for use. The fixed shaft 11 fixes the rotating shell 4 on the fixed block 5 and can control the rotating shell 4 to move outward, pushing the storage plate 2 to move toward the fixed block 5. The sliding shaft 10 enables the storage plate 2 to move and fully enter the inner cavity of the rotating shell 4. While the storage plate 2 moves, the rotating shaft 1 fixes the end of the measuring ruler 7, allowing the measuring ruler 7 to extend smoothly in the fixed block 5 and the slider 6. At the same time, the measuring ruler 7 can be protected when it is between the rotating shell 4 and the storage plate 2.

[0032] Reference Figure 3The lighting auxiliary component includes an inner groove 15, the inner groove 15 is opened inside the slider 6, the top of the inner groove 15 is fixedly connected to the cover plate 9, the inner groove 15 is fixedly connected to the inner groove 15, the inner groove 15 is fixedly connected to the inner groove 15, the inner part of the inner groove 15 is sleeved with a central shaft 13, the outer part of the central shaft 13 is sleeved with a connecting rope 12, the right side of the connecting rope 12 is fixedly connected to the assembly frame 16, and the outer part of the assembly frame 16 is fixedly connected to the lighting lamp 8. The middle part of the spring spring 14 is fixedly connected to the rear end of the central shaft 13. The left side of the assembly frame 16 is plugged into the outer part of the slider 6, and the outer part of the connecting rope 12 runs through the inner part of the slider 6.

[0033] When the lighting lamp 8 is used for auxiliary measurement at night, the connecting rope 12 is connected to the lighting lamp 8, so that the lighting lamp 8 can be pulled out to measure the distant signal lamp equipment. When the connecting rope 12 extends outward, the central axis 13 will rotate accordingly, so that the clockwork spring 14 on the central axis 13 is tightened to keep the connecting rope 12 in an extended state, which is convenient for use. When the lighting lamp 8 is used up, the clockwork spring 14 can rotate to drive the central axis 13 to rotate, and the connecting rope 12 can be retracted and wound around the central axis 13, and then the lighting lamp 8 can be pulled back and fixed in the card slot of the slider 6, so that the lighting lamp 8 will not fall off.

[0034] Working principle: First open the switch frame 3, then open the rotating shell 4 to the front and rear sides through the fixed shaft 5, push the two storage plates 2 to expand to the right and move until they are horizontal, and in this process the measuring ruler 7 is driven to stretch forward for a distance; then push the position between the two storage plates 2, and then push the two storage plates 2 into the inner cavity of the two rotating shells 4 respectively, the rotating shells 4 are retracted and merged, and the measuring ruler 7 is fully extended from the inside of the fixed block 5 and the slider 6, and finally the switch frame 3 is buckled to use the device for measurement. Then open the switch frame 3 and reverse the operation to retract the measuring ruler 7 into the storage plate 2 to protect the measuring ruler 7. When measuring the installation position of the signal light at night, by pulling the lighting lamp 8 outward for use, the connecting rope 12 extends outward, driving the central shaft 13 to rotate, and then tightening the spring spring 14. When the lighting lamp 8 is retracted after use, the spring spring 14 rotates to drive the central shaft 13 to rotate, and then the connecting rope 12 is retracted to the central shaft 13 and the lighting lamp 8 is pulled back into the slot.
