Abstract

The utility model provides an adjustable pressure relief gas spring which is composed of a gas spring cylinder body, a piston and a piston rod riveted with the piston; the cylinder body is welded with a back seal together to construct an airtight gas spring cylinder body; a pressure relief hole and a work position used for mounting the pressure relief part are arranged on the back seal; a seal piece is mounted on the bottom part of the back seal pressure relief work position; a gasket is pressed on the seal piece. The gas spring which adopts the structure to realize the pressure relief adjustment through adjusting the pressure relief screw outwards after the pneumatic is once mounted; thereby, the best application effect is realized through adjustment after the pneumatic is once mounted; the assembly and disassembly of the gas spring are convenient.

Description

A kind of can regulate is rushed down push-type gas spring

Technical field

The utility model relates to a kind of air spring, and particularly a kind of can regulate is rushed down push-type gas spring.

Background technique

The perfection of air spring performance, the increase of function is to change along with client’s demands of applications.Sometimes air spring is on some product or apparatus, the installing/dismounting inconvenience, do not have a kind of can be once good and sound after again through adjusting the air spring that just can reach best using effect.

The model utility content

The utility model provides a kind of can regulate to rush down push-type gas spring.

In order to solve above technical problem, a kind of can regulate of the present utility model is rushed down push-type gas spring, reaching the piston rod of riveting with piston by air spring cylinder body, piston forms, described cylinder body is connected together with back soldering and sealing and forms airtight air spring cylinder body, after seal up to rush down and press the hole and the station that rushes down pressure part is installed, Sealing is contained in the back envelope and rushes down the bottom of pressing station, and pad is pressed on the Sealing.

Described pad seals riveting with the back, rushes down and press the screw front end to be the needle shape, and two small blind holes are anyhow arranged.

Described by pad, seal ring, rush down press that screw forms rush down pressure part can after seal up horizontal assembling, also can vertically assemble at the ear end face that the back is sealed.

The advantage of the above structure of the utility model is: adopt air spring on some product or apparatus, sometimes installing/dismounting inconvenience, for make air spring in use can be once good and sound after again through adjusting the using effect that just can reach the best, the utility model is taked to be connected together in air spring cylinder body and back soldering and sealing and is formed airtight air spring cylinder body, after seal up to rush down and press the hole and the station that rushes down pressure part is installed, Sealing is contained in the back envelope and rushes down the bottom of pressing station, pad is pressed in the structure on the Sealing, and make bearing pressure F1 or pressure F3 15-25% greater than normal use value, press the screw realization adjustable by slowly outwards regulating to rush down, thereby reach once good and sound again through adjusting the using effect that just can reach best.

Description of drawings

Figure is a structural representation of the present utility model.

Embodiment

As shown in the figure, Sealing 6 is installed on the piston 1, piston 1 and piston rod 2 are riveted together, between piston rod 2 and cylinder body 3, be provided with sealing guidance system 9, and cylinder body 3 welds together with back envelope 4 and form airtight air spring cylinder body, be processed with on the back envelope 4 to rush down and press the hole and the station that rushes down pressure part is installed, Sealing 7 is contained in back envelope 4 and rushes down the bottom of pressing station, pad 5 is pressed on the Sealing 7, and with back envelope 4 rivetings, rush down and press screw 8 front ends to be the needle shape, and two small blind holes are anyhow arranged.

When air spring rushes down the realization of pressing performance, the bearing pressure F1 of product or pressure F3 should be greater than the 15-25% of normal use value, slowly outwards regulate to rush down after installing and press screw 8, the sealing center line that little cross-drilled hole withdraws from Sealing 7 on the needle shape just begins to rush down pressure, inwardly regulate to rush down rapidly when rushing down and press screw 8, it is closed rush down pressure to suitable power value.

The above-described this laminated structure that rushes down is not limited only to laterally assembling on back envelope 4, also can vertically assemble at the ear end face of back envelope 4.

Claims (3) – patented gas spring capable of adjusting relief pressure
