Description
Technical Field
The utility model relates to a pneumatic cylinder technical field, concretely relates to high stability multistage pneumatic cylinder.
Background
The telescopic hydraulic cylinder is also called a multi-stage hydraulic cylinder and is formed by sleeving two-stage or multi-stage piston cylinders. The existing multistage hydraulic cylinder mainly comprises a cylinder barrel, a piston rod and other parts, and because the extending stroke of the multistage piston rod is large and the mounting distance of the cylinder barrel is small, in actual use, the large-stroke piston rod brings a large effect on the cylinder barrel, so that the whole multistage hydraulic cylinder has the problem of insufficient stability.
SUMMERY OF THE UTILITY MODEL
There is above-mentioned technical problem to prior art, the utility model provides a simple structure's high stability multistage pneumatic cylinder.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a high stability multistage pneumatic cylinder, includes the cylinder, locates multistage piston rod in the cylinder, piston rod among the multistage piston rod cup joints in proper order, there are inlet and liquid outlet on the cylinder, the periphery side of cylinder is equipped with the supporting wheel, the cylinder passes the supporting wheel, just the inner circle of supporting wheel extends to support and fixes support bar on the cylinder periphery side, the support bar with cylinder periphery side body coupling.
The liquid inlet is provided with a liquid inlet, the liquid outlet is provided with a liquid outlet, the liquid inlet is provided with a liquid outlet, the liquid outlet is provided with a liquid inlet, the liquid outlet is provided with a liquid outlet, the liquid inlet is provided with a liquid inlet, the liquid outlet is provided with a liquid outlet.
And three support bars extend out of each support wheel.
The supporting strips are uniformly distributed on the wheel surface of the supporting wheel.
Wherein, the multistage piston rod is the tertiary piston rod.
The outer tail ends of the two piston rods close to the cylinder barrel extend outwards to the periphery to form a reinforcing barrel.
The utility model has the advantages that:
the utility model discloses a supporting wheel is located to multistage pneumatic cylinder's cylinder periphery side, and this supporting wheel plays the effect of lever, can support the cylinder better, has strengthened the supporting role of cylinder to whole multistage pneumatic cylinder's stability has been improved.
Drawings
Fig. 1 is the utility model discloses a high stability multistage hydraulic cylinder's schematic structure diagram.
Reference numerals:
a cylinder barrel 1; a multi-stage piston rod 2; a liquid inlet 3; a liquid outlet 4; a support wheel 5; a support strip 6; the outer periphery 7 of the cylinder barrel; a reinforcing cylinder 8; a piston rod 9.
Detailed Description
The present invention will be described in detail with reference to the following embodiments and accompanying drawings.
Examples
The high-stability multi-stage hydraulic cylinder of the embodiment is shown in fig. 1 and comprises a cylinder barrel 1 and multi-stage piston rods 2 arranged in the cylinder barrel 1, wherein piston rods 9 in the multi-stage piston rods 2 are sequentially sleeved, and therefore the piston rods 9 can stretch out a larger stroke through stretching. There are inlet 3 and liquid outlet 4 on the cylinder 1, the periphery side of cylinder 1 is equipped with supporting wheel 5, cylinder 1 passes supporting wheel 5, just the inner circle of supporting wheel 5 extends to support and fixes support strip 6 on 1 periphery side 7 of cylinder, support strip 6 with 1 periphery side 7 body coupling of cylinder, this supporting wheel 5 plays the effect of lever for stability when gripping multistage pneumatic cylinder is better.
In this embodiment, there are three supporting wheels 5, two supporting wheels 5 in this embodiment are respectively located at two sides of the liquid inlet 3 and the liquid outlet 4, and another supporting wheel 5 is located at a position between the liquid inlet 3 and the liquid outlet 4, so as to further provide more supporting force.
In this embodiment, three support strips 6 extend from each support wheel 5, and the support strips 6 are uniformly distributed on the wheel surface of the support wheel 5.
In this embodiment, the multistage piston rods 2 are three-stage piston rods 9, the outer ends of the two piston rods 9 close to the cylinder barrel 1 extend outwards to the periphery to form reinforcing cylinders 8, the reinforcing cylinders 8 reinforce the strength of the joints between the piston rods 9 of adjacent stages, so that the joints between the piston rods 9 of adjacent stages are more stable, and the reinforcing cylinders 8 have a diameter larger than that of the piston rods 9, so that when the piston rods 9 retract into the cylinder barrel 1, the reinforcing cylinders 8 stay outside the cylinder barrel 1, and thus the design of the interior of the original cylinder barrel 1 is not affected.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
