Abstract
The utility model relates to a piston and piston rod assembly of a hydrocylinder, which comprises a piston body and a piston rod, wherein the piston body is in a hollow structure. One end of the piston body is provided with a thread portion. The piston rod consists of an installation portion and a rod body portion which is integrally formed with the installation portion. Because the installation portion is in threaded connection with the thread portion, the piston body and the piston rod are mutually connected. The piston and the piston rod can be separated from each other, so the piston or the piston rod can be replaced independently and conveniently. Therefore, using cost is reduced.
Description
[technical field]
The utility model relates to a kind of piston and piston rod assembly of hydraulic jack, belongs to the hydraulic equipment technical field.
[background technique]
Hydraulic jack is a constituent elements commonly used in the machinery, and it is made up of cylinder body, piston rod and piston etc. usually forms, and in use, piston rod drives piston reciprocates.
Yet the piston of the hydraulic jack of existing technology and piston rod fit together through adopting interference fit.And piston is component easy to wear, needs often to change; With respect to piston, the working life of piston rod is then longer relatively.But above-mentioned interference fit can't be separated piston with piston rod, can only piston and piston rod all be changed, and use, maintenance cost increase, and cause the waste of material, are unfavorable for the market competition of product.
Therefore, for solving the problems of the technologies described above, necessary a kind of piston and piston rod assembly with structure improved hydraulic jack be provided, to overcome said defective of the prior art.
[model utility content]
For addressing the above problem, the purpose of the utility model is to provide a kind of replacing convenient, the piston of the hydraulic jack that user cost is low and piston rod assembly.
For realizing above-mentioned purpose, the technological scheme that the utility model is taked is: a kind of piston of hydraulic jack and piston rod assembly, and it comprises piston only and piston rod; Wherein, said piston only is hollow structure, and the one of which end is provided with a screw section; Said piston rod comprise an assembly department and with the integrated rod body part of assembly department, said assembly department and screw section screw togather piston only and piston rod are interconnected.
The piston and the piston rod assembly of the hydraulic jack of the utility model further are set to: the outer surface in said piston only is electroplate with a bronze medal layer, and the thickness of this copper layer is 0.4mm.
Compared with prior art, the utlity model has following beneficial effect: the piston of the hydraulic jack of the utility model and piston rod can be separated from each other, thereby are convenient to change piston or piston rod separately, have reduced user cost.
[description of drawings]
Fig. 1 is piston and the sectional drawing of piston rod assembly of the hydraulic jack of the utility model.
[embodiment]
See also shown in the Figure of description 1, the utility model is a kind of piston and piston rod assembly of hydraulic jack, and it is formed by piston only 1 and the assembling of piston rod 2 two-part members.
Wherein, said piston only 1 is hollow structure, thereby has alleviated its weight and processing materials greatly, has reduced cost of production.One end of this piston only 1 is provided with a screw section 11.Outer surface in said piston only 1 also is electroplate with a bronze medal layer 12, and the thickness of this copper layer 12 is 0.4mm, through the wear resistance that this copper layer 12 can promote this piston only 1 surface greatly is set.
Said piston rod 2 comprise an assembly department 21 and with assembly department 21 integrated rod body part 22.The screw section 11 of said assembly department 21 and piston only 1 screws togather piston only 1 and piston rod 2 is interconnected.When piston only 1 wearing and tearing, only need to change this piston only 1 and get final product, and piston rod 2 still can continue to use.
Above embodiment is merely the preferred embodiment of this creation, not in order to limiting this creation, any modification of being made within all spirit and principles in this creation, is equal to replacement, improvement etc., all should be included within the protection domain of this creation.
Claims (2)
