Description
Technical field
The present invention relates to technical field of hydraulic oil cylinder more particularly to a kind of novel hydraulic oil cylinder top cover to be connected knot with oil cylinder
Structure.
Background technology
A kind of hydraulic cylinder is disclosed in Chinese invention patent CN2506820Y, which has piston rod wader
It puts, wherein, the outside lip-type packing of lip corresponding with the lip-type packing that lip is inside is housed on the gland of oil cylinder,
Pressure chamber is formed between two sealing rings, and oil circuit is provided on gland, oil circuit is connected with external pressure source, so as to two
A sealing ring pressurizes, preferably to strike off the water on piston rod.In above-mentioned patent, gland and oil cylinder connection structure form are more
Using threaded form, gland is sealed with oil cylinder composition surface using O-ring, is positioned using oil cylinder end, can after being used for multiple times
The situation of thread looseness can occur.In order to locking, mostly made using screw thread solid lock glue or end face junction using thread mill drilling
It is fixed with soket head cap screw, prevents from rotating.These modes have after oil cylinder inner sealing system failure after not easy to remove or dismounting
Screw thread or junction surface may be damaged.In external high labor cost, cause maintenance cost big, client is caused to be more willing to buy one
Platform new hydraulic cylinder substitutes damaged hydraulic cylinder.But the Buying Cycle again limits the use of equipment.
The content of the invention
It is an object of the invention to overcome the shortcomings of above-mentioned technology, and a kind of novel hydraulic oil cylinder top cover is provided and is connected with oil cylinder
Binding structure.
The present invention to achieve the above object, using following technical scheme：
A kind of novel hydraulic oil cylinder top cover and oil cylinder connection structure, it is characterised in that：It is buckled including head cover, oil cylinder, the first c-type
Ring and the second c-type retaining ring, the head cover and the oil cylinder clearance fit are opened there are two groove at the inner wall of the oil cylinder, described
First c-type retaining ring and the second c-type retaining ring are separately mounted in the groove, and the head cover is fixed on the first c-type retaining ring
And second between c-type retaining ring.Compared with the prior art, the present apparatus is fixed head cover using two c-type retaining rings, and such structure is tight
It gathers, easy disassembling is easy to repair, also easier for the processing of oil cylinder and head cover, improves processing efficiency and efficiency of assembling.
Preferably, sealed between the head cover and oil cylinder using O-ring seal and back bracket ring.
Preferably, it is provided with locating slot on the right side of the head cover.
The beneficial effects of the invention are as follows:Compared with the prior art, the present apparatus is reasonable in design, and installation is replaced conveniently.This
It invents the head cover of design and the fixed of oil cylinder is designed using unique c-type snap ring structure, two c-type retaining rings are by head cover head cover, and the
One c-type retaining ring blocks the inside of head cover, and the second c-type retaining ring blocks the outside of head cover, so that head cover is fixed together with oil cylinder,
Installation, the replacement for making head cover are more convenient, without specific purpose tool, can be completed by general maintenance personal.
Description of the drawings
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the side view of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings and the preferred embodiment specific embodiment that the present invention will be described in detail.As depicted in figs. 1 and 2,
A kind of novel hydraulic oil cylinder top cover and oil cylinder connection structure, including head cover 1, oil cylinder 2, the first c-type retaining ring 3 and the second c-type retaining ring
4, the head cover and the oil cylinder clearance fit are opened at the inner wall of the oil cylinder there are two groove 5, the first c-type retaining ring and
Second c-type retaining ring is separately mounted in the groove, by the positioning of groove by two c-type retaining ring cards in the trench, c-type retaining ring
With flexible, contraction can take out, and relieving can be with clamping fixed, and the head cover is fixed on the first c-type retaining ring and the 2nd C
Between type retaining ring.The present apparatus is fixed head cover using two c-type retaining rings, and such compact-sized, easy disassembling is easy to repair, right
It is also easier in the processing of oil cylinder and head cover, improve processing efficiency and efficiency of assembling.
In order to make to be sealed between head cover and oil cylinder, O-ring seal 6 and back bracket ring are used between the head cover and oil cylinder
Sealing.
In order to be positioned to the second c-type retaining ring, locating slot 7 is provided on the right side of the head cover, the second c-type button after loading
Ring can be stuck on the table top of locating slot.
The present apparatus is reasonable in design, and installation is replaced conveniently.The head cover and the fixed of oil cylinder that the present invention designs use uniqueness
C-type snap ring structure design, for two c-type retaining rings by head cover head cover, the first c-type retaining ring blocks the inside of head cover, the second c-type retaining ring
The outside of head cover is blocked, so that head cover is fixed together with oil cylinder, makes the installation of head cover, replacement more convenient, without
Specific purpose tool can be completed by general maintenance personal.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications also should
It is considered as protection scope of the present invention.
