Train collision self-turning safety table

A train collision self-turning safety table comprises a table top, guiding sliding blocks, supporting rib plates, a mechanism installation base, a torsional spring, table top locking and positioning keys and a buffer spring. The mechanism installation base is installed on a wall beside a train seat. The two supporting rib plates are installed on the mechanism installation base in parallel. The table top is installed on the two supporting rib plates. The guiding sliding blocks, the torsional spring and the buffer spring are installed below the table top and fix the table top. The seven table top locking and positioning keys are uniformly and fixedly installed on a panel of the mechanism installation base in an arc shape. The train collision self-turning safety table can buffer the collision between a passenger and the table top when a train accident happens, and therefore the response time for the passenger to conduct self-protection actively is prolonged. Through turning of the self-turning table, the contact form between the passenger and the table is changed from line contact to surface contact, and the contact area between the passenger and the table is greatly increased; and according to the Newton's laws, the pressure borne by the passenger can be effectively decreased, and the passive safety of the passenger is improved.

A ferrule-type high-pressure oil pipe joint intelligent manufacturing equipment

The invention provides a ferrule-type high-pressure oil pipe joint intelligent manufacturing equipment, which relates to the technical field of manufacturing equipment, to solve the problem that when the existing high-pressure oil pipe joint manufacturing equipment is in use, due to vibration to remove burrs, it is easy to cause the equipment to shake, and it is easy to break the equipment. The problem of displacement occurs after long-term use, including the main body, the discharge part, the feeding port, and the support part; the main body is a rectangular structure, and the front end of the main body is provided with a rectangular outlet; the discharge part is installed at the right end of the main body. The support is used to set the bottom corner of the main body, so that the support can be in contact with the ground, and then firmly in contact with the ground. When the device is in use, the spring pushes the moving rod to move downward, so that the contact It can always be in contact with the ground. Since the contact piece is made of rubber and the bottom is provided with a wedge-shaped groove, it can effectively contact with the ground, thereby buffering the impact force and avoiding abnormal noise or displacement caused by the contact between the support piece and the ground.
