Abstract
The utility model relates to a split-end hydraulic oil cylinder with an easy-to-replace sealing piece. The split-end hydraulic oil cylinder with the easy-to-replace sealing piece comprises a cylinder body, a piston rod, a piston and a cylinder end. The piston rod is arranged in the cylinder body. The piston is installed on the piston rod. The cylinder end is sheathed on the piston rod and is fixedly installed with the end part of the cylinder body. The cylinder end comprises a split cylinder end and a gland. The end surface of the tail of the split cylinder end is fixedly installed with one end of the cylinder body. A guide piece which is sheathed on the piston rod is arranged in the split cylinder end. The gland is of the shape of a convex circular truncated cone and is provided with a flange and a convex part. The flange of the gland is fixedly installed with the end surface of the mouth of the split cylinder end. The convex part of the gland is inserted into the split cylinder end and presses against the guide piece. An O-ring is installed between the outer wall of the convex part and the inner wall of the split cylinder end. A sealing piece is installed on the inner wall of the top of the convex part of the gland. By adopting the split cylinder end and installing the sealing piece on the gland, the maintenance and the replacement of the sealing piece are facilitated and the working efficiency is improved.
Description
Technical field
The utility model relates to technical field of hydraulic oil cylinder, especially a kind of Split cylinder head hydraulic jack that is easy to change Sealing.
Background technique
In traditional hydraulic jack, cylinder head is independent as a whole, cylinder head is fixedly connected with cylinder body, be directly installed on the interior groove of cylinder head and be used for the Sealing that seals with the guiding element that play the guiding role, traditional oil cylinder design comparison is simple, the problem that all-in-one-piece cylinder head design brings is that installation Sealing and guiding element are relatively more difficult, need the certain operation skill of staff, the height that also reflects cost from this respect, there is such problem for the traditional hydraulic jack of the replacing of Sealing in addition, when needs are changed, whole cylinder head need to be pulled down, again Sealing is taken out, and the Sealing taking-up is also cumbersome, therefore also has the problem of inconvenience aspect safeguarding.
The model utility content
The technical problems to be solved in the utility model is: in order to solve the technical problem that cylinder seal spare is difficult for changing in the prior art, provide a kind of Split cylinder head hydraulic jack that is easy to change Sealing.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of Split cylinder head hydraulic jack that is easy to change Sealing, comprise cylinder body, piston rod, piston and cylinder head, described piston rod is arranged in the cylinder body, described piston is installed on the piston rod, described cylinder head is set on the piston rod and with cylinder ends and fixedly mounts, described cylinder head comprises Split cylinder head and gland, described Split cylinder head tail end face and the fixed installation of cylinder body one end, be provided with the guiding element that is sleeved on the piston rod in the Split cylinder head, described gland is dome platform shape, have flange and protuberance, the oral area end face fixed installation of the flange of gland and Split cylinder head, the protuberance of gland inserts in the Split cylinder head and withstands guiding element, and O type circle is installed between described protuberance outer wall and the Split cylinder head inwall, on the top inner wall of described gland protuberance Sealing is installed.
Sealing and O type circle are not installed on the guiding element in the utility model, but these all are installed on the gland, so just can be convenient for changing Sealing and O type circle, do not need cylinder head is removed fully, only need to pull down gland just can carry out quick-replaceable.
The beneficial effects of the utility model are, the Split cylinder head hydraulic jack that is easy to change Sealing of the present utility model, adopt split type cylinder head design, reduced difficulty of processing, guaranteed the machining accuracy of part, also obtain solution for the difficult problem of changing of Sealing simultaneously, greatly saved the operating time, improved working efficiency.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation that is easy to change the Split cylinder head hydraulic jack of Sealing of the present utility model;
Fig. 2 is the A place enlarged view of Fig. 1.
Among the figure: 1. hanger, 2. piston rod, 3 glands, 31. flanges, 32. protuberances, 4.O type circle, 5. Sealing, 6. guiding element, 7. Split cylinder head, 8. cylinder body.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Shown in Fig. 1 ~ 2, the Split cylinder head hydraulic jack that is easy to change Sealing of the present utility model, comprise cylinder body 8, piston rod 2, piston and cylinder head, piston rod 2 is arranged in the cylinder body 8, be fixedly connected with hanger 1 on the external part of piston rod 2, piston is installed on the piston rod 2, cylinder head is set on the piston rod 2 and with cylinder body 8 end screws and is connected, cylinder head comprises Split cylinder head 7 and gland 3, Split cylinder head 7 tail end faces are connected with cylinder body 8 one end screws, be provided with the guiding element 6 that is sleeved on the piston rod 2 in the Split cylinder head 7, gland 3 is dome platform shape, have flange 31 and protuberance 32, the flange 31 of gland 3 is connected with the oral area end face screw of Split cylinder head 7, and the protuberance 32 of gland 3 inserts in the Split cylinder head 7 and withstands guiding element 6, between protuberance 32 outer walls and Split cylinder head 7 inwalls O type circle 4 is installed, oil just can not spill between Split cylinder head 7 and gland 3 like this, on the top inner wall of gland 3 protuberances 32 Sealing 5 is installed, and having guaranteed so can leakage of oil on the piston rod 2.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
