Side offers sealed groove, is connected with annulus in the sealed groove, is provided with the first neck on the outside of the annulus, and described first
Neck inner loop is provided with the first rubber seal, is provided with the second neck on the inside of the annulus, the second neck inner loop is set
There is the second rubber seal, the annulus periphery is evenly arranged with leakage oil collection hole, and the clamping pad is fixedly connected on guide sleeve
Between, inclined-plane is provided with the guide sleeve external port.
Preferably, first neck and second neck one end offer mounting hole.
Preferably, the limited block and clamping sleeve are formed in one structure.
Preferably, it is provided with fillet at the inclined-plane port.
Preferably, the clamping pad is elastomeric material.
Preferably, it is in close contact between first rubber seal and cylinder main body.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, the annulus and sealed groove of the invention by setting, clamping sleeve are inserted in the piston rod of hydraulic cylinder, circle are propped up by clamping pad
Ring, it is pushed into the inclined-plane of guide sleeve, whole seal is to be pressed onto at guide sleeve inner ring maximum outside diameter at minimum outer diameter, until quilt
It is fully advanced in sealed groove, completes installation, good sealing effect, Stability Analysis of Structures.
2nd, for the present invention by the limited block and inclined-plane of setting, inclined-plane external port is fillet, can effectively protect whole sealing
Part is not hurt in process of press in, and clamping pad is elastomeric material, not only avoids hurting seal, while with seal more
Good fitting, improve assembling effect.
3rd, the first rubber seal and the second rubber seal of the invention by setting, when piston rod moves back and forth, the
One rubber seal is in close contact with cylinder main body, and the second rubber seal is in close contact with piston rod, will not cause hydraulic pressure
Oil is leaked along piston rod, and processing is collected by leakage oil collection hole.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Fig. 1-3 are referred to, the present invention provides a kind of technical scheme：A kind of seal of horizontal hydraulic cylinder, including hydraulic cylinder
Main body 1, annulus 3, guide sleeve 8 and leakage oil collection hole 12, described one end of cylinder main body 1 are connected with piston rod 2, the piston rod
