Description
Technical field
The present invention relates to oil cylinder accessory technical field, specifically a kind of hinged oil cylinder head, for the tailpiece of the piston rod of oil cylinder
It is hinged with other component.
Background technology
Traditional hinged oil cylinder sets universal bearing in the head of its tailpiece of the piston rod, in order to connect and rotate；But
What is be susceptible to is：Prolonged connection and rotation are needed often plus lubricating oil are lubricated it is possible that there is stuck situation, this
Sample is not only troublesome, when being also susceptible to plus add lubricating oil, leads to happening for oil leak.
Invention content
In order to solve the above technical problems, the present invention provides a kind of hinged oil cylinder head.
The invention is realized by the following technical scheme：A kind of hinged oil cylinder head is fixed including articulated joint and with articulated joint
The connecting rod of connection；Through-hole is provided in the articulated joint, universal bearing is installed in articulated joint through-hole；The connecting rod and oil cylinder
Piston rod connects；The axle center of the connecting rod is provided with an oil-through-hole, and oil-through-hole passes straight through to articulated joint close to one end of articulated joint
Through-hole wall, the one end of oil-through-hole far from articulated joint are equipped with plug；A connection is provided in the connecting rod or articulated joint
The side through hole of oil-through-hole；The side through hole outer end is equipped with check valve.
Preferably：The articulated joint is in oblate ring-type, and articulated joint through-hole is located at articulated joint shaft core position.
Preferably：The one end of the connecting rod far from articulated joint is provided with external screw thread, and the oil cylinder piston rod end is provided with connecting
The threaded hole of extension bar end cooperation.
Preferably：The check valve replaces with screw plug.
Hinged oil cylinder head is suitable for operating mode of the articulated joint below connecting rod, in use, by check valve to side through hole
Lubricant is injected, lubricant enters oil-through-hole by side through hole, and final lubricant can be entered in articulated joint through-hole, to universal
Bearing realizes lubrication；Oil-through-hole can store a large amount of lubricant, extend the period of injection lubricant, improve working efficiency.
Compared with prior art, the beneficial effects of the invention are as follows：It is simple in structure, it is easy to use, substantially prolong hinged oil
It in the period of the injection lubricant of cylinder rod head, improves work efficiency.

Fig. 1 is schematic structural view of the invention.
In figure：1st, articulated joint；2nd, connecting rod；3rd, cylinder piston rod；4th, universal bearing；5th, oil-through-hole；6th, plug；7th, side leads to
Hole；8th, check valve.
Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution 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, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of hinged oil cylinder head, the connecting rod 2 being fixedly connected including articulated joint 1 and with articulated joint 1；Hinge
Connector 1 is in oblate ring-type, and 1 through-hole of articulated joint is located at 1 shaft core position of articulated joint, universal bearing 4 is equipped in 1 through-hole of articulated joint.
The one end of connecting rod 2 far from articulated joint 1 is provided with external screw thread, and 3 end of cylinder piston rod is provided with to be coordinated with 2 end of connecting rod
Threaded hole.The axle center of connecting rod 2 is provided with an oil-through-hole 5, and oil-through-hole 5 passes straight through to articulated joint 1 close to one end of articulated joint 1 and leads to
Hole inner wall, the one end of oil-through-hole 5 far from articulated joint 1 are equipped with plug 6；The side that a connection oil-through-hole 5 is provided in connecting rod 2 leads to
Hole 7；7 outer end of side through hole is equipped with check valve 8.
Side through hole 7 can also be opened in articulated joint 1.
Hinged oil cylinder head is suitable for operating mode of the articulated joint below connecting rod, during use：
Lubricant is injected to side through hole by check valve, lubricant enters oil-through-hole by side through hole, and final lubricant can be into
Enter into articulated joint through-hole, universal bearing is realized and is lubricated；Oil-through-hole can store a large amount of lubricant, extend injection lubricant
Period, improve working efficiency.
Due to, the period for injecting lubricant is extended, therefore check valve 8 could alternatively be screw plug, although moistening in injection
During lubrication prescription, need to dismantle screw plug, but entirety still can improve the working efficiency of oil cylinder.Moreover, screw plug makes
Check valve 8 is significantly above with the service life, therefore check valve 8 could alternatively be screw plug can also reduce job costs.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
