Description
Technical field
It the utility model is related to air pressure rod technical field, more particularly to a kind of double-deck scale-up version air pressure rod.
Background technology
Existing air pressure rod sets inner tube in outer tube, pacified respectively at the both ends of inner tube to set outer tube in outer tube
Valve control component and piston component are filled, the gas pressure changed by valve control component in inner tube realizes the relative of piston component and inner tube
Position is so as to realize raising and lowering, but the air pressure rod of this structure easily becomes due to the insufficient strength of outer tube and inner tube
Shape, therefore the stroke distances of this kind of air pressure rod are short.
Utility model content
The purpose of this utility model is to overcome problem above existing for prior art, there is provided a kind of double-deck scale-up version air pressure
Rod improves the bulk strength of air pressure rod, increases the stroke of air pressure rod.
To realize above-mentioned technical purpose and the technique effect, the utility model is achieved through the following technical solutions：
A kind of double-deck scale-up version air pressure rod, including outer tube, outer tube, inner tube, piston component, valve control component, closed component,
The first reinforced pipe is provided with outside the outer tube, the second reinforced pipe is provided with the inside of the outer tube, is pacified in second reinforced pipe
Equipped with bushing, it is fixedly mounted between the outer tube, the second reinforced pipe, bushing three by straight pin, first reinforced pipe is lived
It is dynamic to be socketed in the second reinforced pipe.
Further, the bottom of first reinforced pipe is lower than the bottom of outer tube.
Further, the bottom of first reinforced pipe is lower 8mm than the bottom of outer tube.
Further, the top of second reinforced pipe is higher than the top of outer tube.
Further, the top of second reinforced pipe is higher 10mm than the top of outer tube.
Further, one layer of viscose is smeared at the connecting sewing of first reinforced pipe and outer tube.
Further, the front end of the outer tube and the side wall of the second reinforced pipe are carried out by gas tungsten arc welding
Welding.
The beneficial effects of the utility model are：The first reinforced pipe is put in outer tube peripheral hardware, increases the intensity in the middle part of outer tube, outside
Internal surface of sleeve pipe sets the second reinforced pipe, not only improves intensity, also extends the length of outer tube, adds the stroke of air pressure rod.
Brief description of the drawings
Accompanying drawing described herein is used for providing further understanding to of the present utility model, forms the part of the application,
Schematic description and description of the present utility model is used to explain the utility model, does not form to of the present utility model improper
Limit.In the accompanying drawings：
Fig. 1 is overall structure diagram of the present utility model.
Label declaration in figure：1- valve controls component, 2- outer tubes, 3- inner tubes, the reinforced pipes of 4- first, 5- bushings, 6- second strengthen
Pipe, 7- straight pins, 8- piston components, 9- piston rods, the closed components of 10-, 11- supports backing plate, 12- split pins.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in detail.
As shown in figure 1, a kind of double-deck scale-up version air pressure rod, including outer tube 13, outer tube 2, inner tube 3, piston component 8, valve
Component 1, closed component 10 are controlled, inner tube 3 is arranged in outer tube 2, and valve control component 1 is located at the front end of inner tube 3, including piston component 8
Piston movement in pipe 3, closed component 10 are arranged in the afterbody of outer tube 2, and the afterbody of piston rod 9 of piston component 8 passes through split pin
12 are arranged on the support backing plate 11 of the afterbody of outer tube 13, and the first reinforced pipe 4 is provided with outside outer tube 2, and the inner side of outer tube 13 is set
There is the second reinforced pipe 6, bushing 5 is installed in second reinforced pipe 6, passes through circle between outer tube 13, the second reinforced pipe 6, the three of bushing 5
Pin 7 is fixedly mounted, and straight pin 7 has two and is symmetrically installed, and the first reinforced pipe 4 is actively socketed in the second reinforced pipe 6.
The bottom of first reinforced pipe 4 is lower than the bottom of outer tube 2, and the bottom of the first reinforced pipe 4 is lower 8mm than the bottom of outer tube 2.
This is designed to the stroke for extending air pressure rod downwards, and the minimum point for enabling air pressure rod to reach is lower.
The top of second reinforced pipe 6 is higher than the top of outer tube 13, the top of the top of the second reinforced pipe 6 than outer tube 13
High 10mm.This is designed to the stroke for extending air pressure rod upwards, and the peak for enabling air pressure rod to reach is higher.
First reinforced pipe 4 makes the connection between the reinforced pipe 4 of outer tube 2 and first with smearing one layer of viscose at the connecting sewing of outer tube 2
It is more firm.
The front end of outer tube 13 and the side wall of the second reinforced pipe 6 are welded by gas tungsten arc welding.
First reinforced pipe 4 is set outside outer tube 2, the intensity at the middle part of increase outer tube 2, sets second to increase in the inwall of outer tube 13
Strong pipe 6, intensity is not only improved, also extend the length of outer tube 13, add the stroke of air pressure rod.
The advantages of general principle of the present utility model, principal character and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
