Abstract
The invention relates to the technical field of pneumatic rods, and particularly relates to a rear propping sleeve of a pneumatic rod. The rear propping sleeve of the pneumatic rod is in a shape of a circular ring, wherein a guide hole is formed in the center of the rear propping sleeve; a step is arranged on the front surface of the rear propping sleeve; grooves are formed in the circular side of the guide hole; guide ribs are arranged on the outer circular side of the rear propping sleeve; and counter bores are formed in the rear propping sleeve. The rear propping sleeve of the pneumatic rod is simple in structure and manufactured from POM (Polyoxymethylene) material, so that the strength can be improved; three grooves are added in the guide hole, so that the rear propping sleeve can be prevented from being pressed and deformed, and a piston rod can be held tightly, and as a result, the frictional force can be increased.
Description
Technical field
The present invention relates to top cover after one, particularly relate to the rear top cover of a kind of air-leg.
Background technology
Lifting air lever is used widely in daily life at present, and that applies in office furniture especially is the widest
General, it is the main composition part of office revolving chair, the rear top cover used in lifting air lever in prior art uses ABS material, its
Structure is the most yielding and the problem such as insufficient strength, causes the complaint of client to raise, causes quality cost to increase.
Summary of the invention
Present invention seek to address that drawbacks described above, it is provided that the rear top cover of a kind of air-leg.
In order to overcome defect present in background technology, the technical solution adopted for the present invention to solve the technical problems is:
After described in the rear top cover of this air-leg, top cover is toroidal, is provided with pilot hole, the front of rear top cover at the center of rear top cover
Being provided with step, the round edge of described pilot hole is provided with groove, and the outer circumferential edge of rear top cover is provided with guiding rib, sets in described rear top cover
There is counterbore.
According to another embodiment of the invention, farther include between described guiding rib in equidistantly in rear top cover
Outer circumferential edge on.
According to another embodiment of the invention, farther include between described groove in equidistantly in pilot hole
On round edge.
According to another embodiment of the invention, farther include between described counterbore in equidistantly in rear top cover
In.
The invention has the beneficial effects as follows: the simple in construction of the rear top cover of this air-leg, using POM material, intensity increases,
Pilot hole increases by 3 grooves, is possible to prevent rear top cover compressive deformation, holds piston rod tightly, the effect of increasing friction force.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of sectional view of the present invention；
Wherein: 1, guiding rib, 2, groove, 3, pilot hole, 4, counterbore, 5, step.
Detailed description of the invention
As depicted in figs. 1 and 2, the rear top cover in figure is toroidal, is provided with pilot hole 3 at the center of rear top cover, pushes up afterwards
The front of set is provided with step 5, and the round edge of pilot hole 3 is provided with groove 2, and the outer circumferential edge of rear top cover is provided with guiding rib 1, rear top cover
Inside it is provided with counterbore 4.In equidistantly in the outer circumferential edge of rear top cover between guiding rib 1.Between groove 2 in equidistantly in
On the round edge of pilot hole 3.In equidistantly in rear top cover between counterbore 4.
The round edge of pilot hole 3 is provided with groove 2, Internal Hole Deformation when being possible to prevent to seal by the groove 2 increased.Rear top cover
Outer circumferential edge be provided with guiding rib 1, the setting of guiding rib 1 can also increasing friction force, be provided with counterbore 4 in rear top cover, counterbore 4 exists
Add and can effectively save material man-hour, and there is enough intensity.
The simple in construction of this rear top cover, integral material uses POM material, and intensity increases.
