Background

The air spring is an industrial accessory which can play roles of supporting, buffering, braking, height adjustment, angle adjustment and the like. The principle is that inert gas is filled in a closed pressure cylinder, so that the pressure in a cavity is higher than the atmospheric pressure, and the motion 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.

The mounting dimension of current air spring outer tube is always fixed, can not adapt to different occasions, and the air spring outer tube need bear inside gas pressure when using, when pressure load is too big, easily causes the air spring to explode and splits, causes personnel's damage.

In order to adapt to different occasions and change the installation size of the air spring, and when the outer sleeve of the air spring bears too much pressure, an alarm is given to remind workers to repair the outer sleeve, so that the problem that the personnel are damaged due to burst of the air spring is solved, and the problem that the outer sleeve for the air spring solves the problem is solved.

SUMMERY OF THE UTILITY MODEL

For the mounting dimension who solves above-mentioned current air spring outer tube is always fixed, can not be adapted to different occasions, and the air spring outer tube when using, need bear inside gas pressure, when pressure load is too big, easily arouse the air spring to explode and split, cause the problem of personnel's damage, the air spring is applicable to different occasions more than the realization, and mounting dimension can change, and bear when pressure when too big when the air spring outer tube, send out the police dispatch newspaper, remind the staff to restore, avoid the air spring to explode and split the mesh that causes personnel's damage, the utility model discloses a following technical scheme realizes: the utility model provides an outer tube for air spring, includes the body, the outer wall fixed mounting of body has solid fixed ring, the through-hole has been seted up to solid fixed ring's inside, the inside rotation of through-hole installs the screw rod, the outer wall threaded connection of screw rod has the removal dish, the bottom fixed mounting of removal dish has the drive pole, the bottom fixed mounting of drive pole has the mount pad.

Furthermore, the outer wall fixed mounting of screw rod has the limiting plate, and the limiting plate has two, is located solid fixed ring top and below respectively, has played the problem of avoiding the screw rod shift position.

Furthermore, a handle is fixedly installed at the top of the screw rod, and a groove is formed in the handle, so that the friction force of the handle is enhanced, and the effect of driving the screw rod to rotate by manually rotating the handle is facilitated.

Further, solid fixed ring's top fixed mounting has the detection ring, the inner wall fixed mounting who detects the ring has the controller, the top fixed mounting who detects the ring has the alarm, controller control the alarm, the outer wall fixed mounting of body has the contact, and when the inside atmospheric pressure increase of body, it outwards expands to lead to the body, will lead to contact controller, and controller control alarm triggers the alarm, reminds operating personnel to inspect prosthetic effect to the body.

Further, the contact with the controller is just right, ensures that the contact can contact with the controller, and both contact when initiating, but the contact does not extrude the controller when initiating, and the more accurate detection body collision of being convenient for changes, and both figures of contact and controller are equal, one-to-one.

The utility model provides an outer tube for air spring. The method has the following beneficial effects:

1. this outer tube for air spring rotates in the through-hole of screw rod on solid fixed ring, because the screw rod adopts threaded connection with the removal dish, along with the screw rod rotates, the removal dish will remove along the screw rod to driving the position that the drive rod changed the mount pad, realized that the mount pad position is adjustable, make the body be applicable to the effect of different occasions.

2. This outer tube for air spring through set up the contact at the body outer wall, after the body because atmospheric pressure inflation, will drive the contact and extrude towards the controller, the controller receives the extrusion and triggers the back, will control the alarm and produce the police dispatch newspaper, has realized the real-time detection body inflation condition, avoids the body to explode the problem that leads to personnel's damage.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The embodiment of the outer sleeve for the gas spring is as follows:

example (b):

please refer to fig. 1-4, an outer sleeve for an air spring, including a pipe body 1, the outer wall of the pipe body 1 is fixedly provided with a fixing ring 2, the inside of the fixing ring 2 is provided with a through hole 3, the inside of the through hole 3 is rotated and provided with a screw rod 4, the top of the screw rod 4 is fixedly provided with a handle 41, the handle 41 is provided with a groove, the friction force of the handle 41 is enhanced, the manual rotation of the handle 41 is facilitated to drive the rotation effect of the screw rod 4, the outer wall of the screw rod 4 is fixedly provided with a limiting plate 5, the limiting plates 5 are two, the limiting plates are respectively positioned above and below the fixing ring 2, the problem of avoiding the moving position of the screw rod 4 is solved, the outer wall of the screw rod 4 is in threaded connection with a moving disc 6, the bottom of the moving disc 6 is fixedly provided with a driving rod 7, and the bottom of the driving rod 7 is fixedly provided with a mounting base 8.

Fixed ring 2's top fixed mounting has detection ring 9, detection ring 9's inner wall fixed mounting has controller 91, detection ring 9's top fixed mounting has alarm 92, controller 91 controls alarm 92, the outer wall fixed mounting of body 1 has contact 93, contact 93 is just right with controller 91, ensure that contact 93 can contact with controller 91, and both contact when initiating, but contact 93 does not extrude controller 91 when initiating, be convenient for more accurate detection body 1 collision change, contact 93 is equal with both figures of controller 91, one-to-one, increase when the inside atmospheric pressure of body 1, lead to the outside inflation of body 1, will lead to contact 93 contact control ware 91, controller 91 control alarm 92 triggers the alarm, remind operating personnel to inspect prosthetic effect to body 1.

The theory of operation, through manual control handle 41, because set up the recess on the handle 41, make things convenient for manual rotation handle 41 to drive screw rod 4 and rotate, because limiting plate 5's existence, the problem of 4 shift positions of screw rod has been avoided, along with screw rod 4 rotates the back, because screw rod 4 adopts threaded connection with removal dish 6, it will remove along screw rod 4 to remove dish 6, it drives the removal of band pulley 7 to remove dish 6, it drives mount pad 8 self positions to drive band pulley 7 afterwards, thereby it is variable to have realized 1 mounted position of body, ensure that body 1 is applicable to the installation environment of different length, the suitability of body 1 has been improved.
