Description

Stamping forming's train hand wheel Technical Field The utility model relates to the technical field of handwheels, in particular to a stamping forming train handwheel. Background The carriage of some trains is provided with a hand wheel type emergency braking device, manual rotation operation is needed, and because the hand wheel is generally fixedly connected with the rotating rod, the hand wheel can drive the rotating rod to rotate when rotating to complete emergency braking, but sometimes the situation of false touch is caused, the rotating of the hand wheel drives the rotating rod to rotate, so that the train is braked accidentally, emergency braking is caused, passengers fall down or goods shift due to the inertia of passengers and goods, and dangerous accidents are caused. Disclosure of utility model The utility model aims to solve the defect that in the prior art, a hand wheel rotates to drive a rotating rod to rotate due to false touch, so that dangerous accidents are caused. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides a stamping forming's train hand wheel, includes the hand wheel main part, the hand wheel main part cover is established on the bull stick, fixedly connected with keeps off the ring down on the bull stick and keeps off the ring with last, the hand wheel main part is located down keeps off between ring and the last fender ring, set up the installation cavity in the hand wheel main part, be connected with the spliced pole through trigger mechanism in the installation cavity, it is provided with the through-hole to run through on the installation cavity, the spliced pole has been seted up on the bull stick, the spliced pole can pass the through-hole and enter into the spliced pole in. Preferably, the hand wheel body is provided with an elastic layer. Preferably, the trigger mechanism comprises a roller, the roller is mounted on the insertion column, a moving block is abutted to the roller, an inclined surface is arranged on the moving block, a moving part is fixedly connected to the moving block and located under the upper baffle ring, and a first spring is fixedly connected between the moving block and the mounting cavity. Preferably, a sealing cover is arranged on the mounting cavity, a through groove is formed in the sealing cover, and the moving part penetrates through the through groove. Preferably, the mounting cavity is provided with a threaded hole, a plurality of screws are arranged at equal intervals on the circumference of the sealing cover, and the screws are in threaded connection with the threaded hole. Preferably, the insertion column is fixedly connected with a connecting ring, the connecting ring and the inner wall of the mounting cavity are fixedly connected with a second spring, and the second spring is sleeved on the insertion column. Preferably, the rotating rod is provided with a wear-resistant layer. The stamping forming train hand wheel has the beneficial effects that in a normal state, the insertion column is not positioned in the insertion hole, so that when the false touch occurs, only the hand wheel rotates, the rotating rod does not rotate, the situation of emergency braking caused by the false touch is avoided, and dangerous accidents are prevented from being caused.
