Abstract
The utility model is related to technical field of hydraulic oil cylinder, more particularly to a kind of novel hydraulic oil cylinder top cover and oil cylinder connection structure, including head cover, oil cylinder, the first c-type retaining ring and the second c-type retaining ring, the head cover and the oil cylinder clearance fit, groove there are two being opened at the inner wall of the oil cylinder, the first c-type retaining ring and the second c-type retaining ring are separately mounted in the groove, and the head cover is fixed between the first c-type retaining ring and the second c-type retaining ring.Compared with the existing technology, the present apparatus is fixed head cover using two c-type retaining rings, and such compact-sized, easy disassembling is easy to repair, also easier for the processing of oil cylinder and head cover, improves processing efficiency and efficiency of assembling.
Description
Technical field
The utility model is related to technical field of hydraulic oil cylinder more particularly to a kind of novel hydraulic oil cylinder top cover to be connect with oil cylinder
Structure.
Background technology
A kind of hydraulic cylinder is disclosed in Chinese utility model patent CN2506820Y, the hydraulic cylinder is anti-with piston rod
Water installations, wherein equipped with the lip packing that lip corresponding with the lip-type packing that lip is inside is outside on the gland of oil cylinder
Circle, forms pressure chamber, and oil circuit is provided on gland between two sealing rings, and oil circuit is connect with external pressure source, from
And pressurize to two sealing rings, preferably to strike off the water on piston rod.In above-mentioned patent, gland and oil cylinder connection structure
Form mostly uses threaded form, and gland is sealed using O-ring with oil cylinder joint surface, positioned using oil cylinder end, repeatedly made
The situation of thread looseness is likely to occur after.In order to locking, mostly use screw thread solid lock glue or end face junction and use processing spiral shell
Pit is fixed using soket head cap screw, prevents from rotating.These modes are not easy to remove or tear open after oil cylinder inner sealing system failure
Damage screw thread or junction surface are possible to after unloading.In external high labor cost, causes maintenance cost big, client is caused more to be willing to
Meaning buys a new hydraulic cylinder to substitute damaged hydraulic cylinder.But the Buying Cycle again limits the use of equipment.
Utility model content
Purpose of the utility model is to overcome the shortcomings of the above technology, and to provide a kind of novel hydraulic oil cylinder top covers and oil
Cylinder connection structure.
The utility model 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 open that there are two grooves 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 existing technology, 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, it is sealed using O-ring seal and back bracket ring between the head cover and oil cylinder.
Preferably, it is provided with locating slot on the right side of the head cover.
The utility model has the beneficial effects that:Compared with the existing technology, the present apparatus is reasonable in design, installation, replacement side
Just.Head cover that the present invention designs and the fixed of oil cylinder are designed using unique c-type snap ring structure, and two c-type retaining rings are by head cover top
Lid, the first c-type retaining ring block the inside of head cover, and the second c-type retaining ring blocks the outside of head cover, to make head cover be fixed on oil cylinder
Together, make installation, the replacement of head cover more convenient, be not necessarily to specific purpose tool, can be completed by general maintenance personal.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the side view of the utility model.
Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment of the present utility model is described in detail in preferred embodiment.Such as Fig. 1 and Fig. 2 institutes
Show, 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 are buckled
Ring 4, the head cover and the oil cylinder clearance fit open that there are two groove 5, the first c-type retaining rings at the inner wall of the oil cylinder
Be separately mounted in the groove with the second c-type retaining ring, by the positioning of groove by two c-type retaining ring cards in the trench, c-type button
Annulus is flexible, and contraction can take out, and relieving can be fixed on the first c-type retaining ring and with clamping fixed, the head cover
Between two c-type retaining rings.The present apparatus is fixed head cover using two c-type retaining rings, and such compact-sized, easy disassembling is easy to repair,
It is also easier for 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 for blocking head cover keeps the installation of head cover, replacement more convenient, is not necessarily to make head cover be fixed together with oil cylinder
Specific purpose tool can be completed by general maintenance personal.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
