[0002] As an important means of transportation, it is very important to ensure the safe operation of the subway. Daily inspections of subway lines and equipment are very important. Subway inspectors usually conduct status inspections of subway lines, equipment and contact rails when the subway stops at night to ensure that the subway can operate normally the next day. When conducting subway inspections, they are all conducted manually with handheld subway inspection devices.

[0003] When the current handheld subway inspection device is in use, a worker holds the handle of the handheld subway inspection device with his hand, and then can inspect the subway line. Since the handle of the handheld subway inspection device does not have a telescopic function, it is not convenient to manually inspect the low or high lines. Therefore, it is necessary to design a handheld subway inspection device. Summary of the invention

When in use, a worker holds the telescopic rod with one hand and pulls the machine body with the other hand to move. At this time, with the cooperation of the telescopic rod, the machine body can be kept away from the worker's hand, thereby lengthening the handle of the handheld subway inspection device to facilitate inspection of low and high places of the subway line. At the same time, the friction between the worker's palm and the telescopic rod can be increased under the action of the anti-slip cover, which is conducive to preventing the machine body from slipping from the hand.

[0018] Compared with the prior art, the handheld subway inspection device is provided with a fixed cylinder, an end cover, a torsion spring, a rotating shaft, a winding roller, a connecting rope and an elastic rope loop. When in use, the elastic rope loop is put on the worker's wrist. After the machine body falls off from the hand, the winding roller can be driven to rotate under the action of the connecting rope, and then the torsion spring can be generated with the cooperation of the rotating shaft. The twisted torsion spring is convenient to drive the winding roller to wind up the connecting rope. In this way, under the action of the connecting rope and the elastic rope loop, the machine body can be prevented from directly contacting the ground after falling off from the hand, thereby improving the protection of the machine body.

[0025] 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.

[0026] Reference Figure 1-4 The utility model provides a handheld subway inspection device, including a body 1, a fixed seat 5 is fixedly connected to the rear end of the body 1, a connecting rod 6 is fixedly connected inside the fixed seat 5, a telescopic rod 7 is fixedly connected to the lower end of the connecting rod 6, and an anti-slip sleeve 4 is provided on the circumferential surface of the telescopic rod 7.

[0027] Specifically, when in use, the worker holds the telescopic rod 7 with one hand and pulls the machine body 1 with the other hand to move. At this time, with the cooperation of the telescopic rod 7, the machine body 1 can be kept away from the worker's hand, thereby lengthening the handle of the handheld subway inspection device to facilitate inspection of low and high places of the subway line. At the same time, the friction between the worker's palm and the telescopic rod 7 can be increased under the action of the anti-slip sleeve 4, which is conducive to preventing the machine body 1 from slipping from the hand.

[0028] The body 1 is provided with a cavity 12 inside, and a reset assembly 8 and a winding assembly 9 are provided inside the cavity 12, and a connecting rope 10 is wound inside the winding assembly 9. The winding assembly 9 includes a rotating shaft 901 and a winding roller 902. The rotating shaft 901 is rotatably connected inside the cavity 12, and the winding roller 902 is fixedly connected to the circumferential surface of the rotating shaft 901. The connecting rope 10 is wound inside the winding roller 902, and one end of the connecting rope 10 away from the winding roller 902 passes out of the body 1. The reset assembly 8 includes a fixed cylinder 801, an end cover 802, and a torsion spring 803. The inner wall of the cavity 12 is fixedly connected to the fixed cylinder 801, and the end cover 802 and the torsion spring 803 are fixedly connected inside the fixed cylinder 801. The end cover 802 is rotatably connected to the rotating shaft 901, and the torsion spring 803 is fixedly connected to the rotating shaft 901. A circular hole 11 is formed on the lower end surface of the body 1 , and the circular hole 11 is connected to the cavity 12 . The connecting rope 10 passes through the circular hole 11 , and one end of the connecting rope 10 away from the winding roller 902 is fixedly connected to the elastic rope loop 3 .

[0029] Specifically, when in use, the elastic rope loop 3 is put on the worker's wrist. After the machine body 1 falls off from the hand, the winding roller 902 can be driven to rotate under the action of the connecting rope 10, and then the torsion spring 803 can be generated with the cooperation of the rotating shaft 901. The twisted torsion spring 803 can easily drive the winding roller 902 to reel in the connecting rope 10. In this way, under the action of the connecting rope 10 and the elastic rope loop 3, the machine body 1 can be prevented from directly contacting the ground after falling off from the hand, thereby improving the protection of the machine body 1.

[0030] A baffle 13 is fixedly connected to the circumferential surface of one end of the connecting rope 10 passing through the body 1. The diameter of the baffle 13 is larger than the diameter of the circular hole 11. When working, the baffle 13 can prevent the extended end of the connecting rope 10 from completely entering the cavity 12 under the action of the baffle 13.

[0031] The body 1 is fixedly connected with a corner wrap 2, four of which are made of silicone material. When working, the body 1 can be protected by the wrapping angle 2, thereby increasing the service life of the body 1.
