Abstract
The utility model provides an air cylinder belongs to the air cylinder field. It has solved the problem that current air cylinder during operation piston rod can rotate. This air cylinder includes the cylinder body and establishes front end housing and the rear end cap in cylinder body front end and rear end respectively, still including establish in the cylinder body the piston and from the piston rod of front end housing in stretching into the cylinder body, piston rod bottom end wears to establish and fixes on the piston, piston rod bottom end is equipped with the bar spacing hole coaxial with the piston rod, still include the gag lever post of fixing with the rear end cap, and the gag lever post cross -section is the same with spacing hole cross -section and perpendicular with the piston rod, and be non -circular structure, the gag lever post penetrates spacing hole, and the piston can drive the piston rod and move along the cylinder body axis, and form spacing cooperation structure through gag lever post and the cooperation of spacing hole. It is rotatory that this air cylinder avoids the piston rod to take place when the piston rod removes, is fit for more occasions and uses, can avoid moreover changing current seal structure, and can not cause the influence to seal structure for the transformation degree of difficulty reduces.
Description
Technical field
This utility model belongs to cylinder technical field, relates to a kind of cylinder.
Background technology
Existing cylinder is when driving piston to move reciprocatingly in cylinder body by piston rod, and piston rod can rotate, and therefore cylinder is not suitable for needing the occasion of translation to use, it is therefore necessary to improve.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, it is provided that a kind of cylinder of rotating of piston rod when avoiding using.
The purpose of this utility model can be realized by following technical proposal: a kind of cylinder, including cylinder body and the drive end bearing bracket and the rear end cap that are respectively provided at cylinder body front-end and back-end, also include the piston being located in cylinder body and the piston rod stretching in cylinder body from drive end bearing bracket, piston rod bottom wears and is fixed on piston, it is characterized in that: piston rod bottom is provided with the bar shaped spacing hole coaxial with piston rod, also include the gag lever post fixing with rear end cap, and gag lever post cross section is identical with spacing hole cross section and vertical with piston rod, and in non-circular structure, gag lever post penetrates spacing hole, and piston can drive piston rod to move along cylinder body axis, and cooperatively form spacing fit structure by gag lever post and spacing hole.
Owing to gag lever post cross section is identical with spacing hole cross section and in non-circular structure, therefore piston can drive piston rod to move along cylinder body axis, and cooperatively form spacing fit structure by gag lever post and spacing hole, piston rod can be avoided to rotate when piston rod moves, therefore this cylinder is suitable for the use of more occasion, and be avoided that the existing sealing structure of change, and will not impact sealing structure so that transformation difficulty reduces.
In above-mentioned a kind of cylinder, gag lever post is hollow rod-like structure, and gag lever post top and gag lever post are respectively equipped with the air-vent being interconnected on the bar wall of rear end cap.
Therefore can when gag lever post and spacing hole coordinate, it is to avoid between gag lever post and spacing hole, air pressure increases.
In above-mentioned a kind of cylinder, at the bottom of described spacing hole hole and between gag lever post, it is provided with damping spring.
Play the effect of damping, buffering.
In above-mentioned a kind of cylinder, described gag lever post cross section and spacing hole cross section are regular polygon or ellipse.
Compared with prior art, this utility model has the advantage that
Owing to gag lever post cross section is identical with spacing hole cross section and in non-circular structure, therefore piston can drive piston rod to move along cylinder body axis, and cooperatively form spacing fit structure by gag lever post and spacing hole, piston rod can be avoided to rotate when piston rod moves, therefore this cylinder is suitable for the use of more occasion, and be avoided that the existing sealing structure of change, and will not impact sealing structure so that transformation difficulty reduces.

Detailed description of the invention
The following is specific embodiment of the utility model and in conjunction with accompanying drawing, the technical solution of the utility model is further described, but this utility model is not limited to these embodiments.
As shown in Figure 1, this utility model one cylinder, including cylinder body 1 and the drive end bearing bracket 11 and the rear end cap 12 that are respectively provided at cylinder body 1 front-end and back-end, also include the piston 2 being located in cylinder body 1 and the piston rod 21 stretching in cylinder body 1 from drive end bearing bracket 11, piston rod 21 bottom wears to be fixed on the piston 2, piston rod 21 bottom is provided with the bar shaped spacing hole 22 coaxial with piston rod 21, also include the gag lever post 13 fixing with rear end cap 12, and gag lever post 13 cross section is identical with spacing hole 22 cross section and vertical with piston rod 21, and in non-circular structure, gag lever post 13 penetrates spacing hole 22, and piston 2 can drive piston rod 21 to move along cylinder body 1 axis, and cooperatively form spacing fit structure by gag lever post 13 and spacing hole 22.
Further, gag lever post 13 is in hollow rod-like structure, and gag lever post 13 top and gag lever post 13 are respectively equipped with the air-vent 14 being interconnected on the bar wall of rear end cap 12.It is provided with damping spring 23 at the bottom of spacing hole 22 hole and between gag lever post 13.Gag lever post 13 cross section and spacing hole 22 cross section are regular polygon or ellipse.
Owing to gag lever post 13 cross section is identical with spacing hole 22 cross section and in non-circular structure, therefore piston 2 can drive piston rod 21 to move along cylinder body 1 axis, and cooperatively form spacing fit structure by gag lever post 13 and spacing hole 22, piston rod 21 can be avoided to rotate when piston rod 21 moves, therefore this cylinder is suitable for the use of more occasion, and be avoided that the existing sealing structure of change, and will not impact sealing structure so that transformation difficulty reduces.
Specific embodiment described herein is only to this utility model spirit explanation for example.Described specific embodiment can be made various amendment or supplements or adopt similar mode to substitute by this utility model person of ordinary skill in the field, but without departing from spirit of the present utility model or surmount the scope that appended claims is defined.
Although more employing the terms such as cylinder body 1, drive end bearing bracket 11, rear end cap 12, gag lever post 13, air-vent 14, piston 2, piston rod 21, spacing hole 22, damping spring 23 herein, but it is not precluded from using the probability of other term.These terms are used to be only used to describe and explain essence of the present utility model more easily；It is all contrary with this utility model spirit for being construed as any additional restriction.
