Description

Pneumatic stay bar with protective cover

Technical Field

The utility model relates to a pneumatic stay bar, in particular to a pneumatic stay bar with a protective cover.

Background

Pneumatic supporting rod (gas spring) is an industrial fitting with functions of supporting, buffering, braking, height adjustment, angle adjustment and the like. The pneumatic stay rod principle is that inert gas or oil-gas mixture is filled into a closed pressure cylinder to make the pressure in a cavity be several times or tens times higher than the atmospheric pressure, and the movement of a piston rod is realized by utilizing the pressure difference generated by the fact that the cross section area of the piston rod is smaller than that of the piston. Currently, there are two general disadvantages to pneumatic braces used in tailgates on the market: the piston rod is exposed outside or has a complex structure. The piston rod is exposed outside, and under complicated operating mode, if influenced by dust, salt, alkali, high temperature, high humidity, etc., the piston rod is easy to rust or damage, and later influences the internal seal, and the function is invalid. If the automobile tail door is used, under the condition that the piston rod fails, the tail door can be even dropped to smash the head of a user, and potential safety hazards exist. In another complex structure, the pneumatic stay bar is wrapped by the plastic sleeve, so that the cost of parts is increased, and the use cost is increased.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions in the embodiments of the present utility model will be clearly and completely described in the following in conjunction with the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments. Embodiments of the utility model are described herein in terms of various specific embodiments, including those that are apparent to those of ordinary skill in the art and all that come within the scope of the utility model.

As shown in fig. 1-6, the piston rod 3 is inserted into the steel tube 8 from one end of the steel tube 8, the other end of the steel tube 8 is connected with the ball socket one 9, one end of the piston rod 3 is connected with the piston assembly 7 and is positioned in the steel tube 8, the other end of the piston rod is exposed outside the steel tube 8, the end of the piston rod is connected with the ball socket two 1, one end of the protective cover 4 is connected with the outer side surface of one end of the steel tube 8, the other end of the protective cover 4 is connected with the ball socket two 1, and the piston rod 3 exposed outside the steel tube 8 is arranged in the protective cover 4. The protection cover, the ball socket and the steel pipe form a relatively sealed environment, so that rainwater erosion is avoided, the service life of the metal piston rod can be greatly prolonged, the connection of the piston rod and the ball socket is prevented from being influenced due to exposure to rust, even the pneumatic stay rod is broken, and potential safety hazards appear. The piston rod is wrapped in and hardly influenced by external humidity, temperature, salt and alkali and chemicals, and is stable in use and high in safety. Compared with the metal pneumatic stay bar with two plastic sleeve sleeves outside, the air stay bar with the protective cover can obviously reduce the cost without affecting the service performance, and can still meet the practical application.
