Abstract
The utility model relates to a self-locking folding base plate oil jack which comprises a base, a shell arranged on the base, a piston rod arranged in the shell and a self-locking nut arranged on the upper portion of the shell. Folding plates are arranged on the two sides of the base. The self-locking folding base plate oil jack has the self-locking function, the folding plates are used for enlarging the stressed area of the base and stability of the structure is reinforced.
Description
Technical field
The utility model is specifically related to self-locking folding base plate oil jack.
Background technology
Oil jack is country's sizing new range product, oil jack compact conformation, volume is little, lightweight, easy to carry, be widely used in factory position warehouse, bridge, harbour, the hoisting operation of the department such as communications and transportation and building engineering, it is conventional a kind of lifting gear in producing, its simple structure, easy to operate, repair automobile, trac.s etc. are commonly used it by vehicle body jack-up, be convenient to repair, oil jack is according to the principle work of Pascal's law, it is by fuel tank, two oil pressure cylinders that vary in size, rocking bar forms with several parts such as closing needle-valve.When work, mention valve piston oil is sucked to little oil pressure cylinder, oil pressure is entered to large oil pressure cylinder in the time depressing valve piston, by the control of two valves, valve piston passes to large piston to oily pressure, weight jack-up is come, valve piston is reciprocating action constantly, just weight can be pushed up to certain height, work complete, open and close needle-valve, large oil pressure cylinder and fuel tank are communicated with, at this moment, as long as pressure a little on large piston, large piston can fall, oil is got back in fuel tank and is gone, in current being seen oil jack, do not there is the structure of auto-lock function and the area of thrust surface of base are little, on loose ground, use and will could use by upholder.
Summary of the invention
Technical problem to be solved in the utility model is to provide self-locking folding base plate oil jack, designs a kind of have auto-lock function and the folding board-like area of thrust surface that increase base, strengthens the stability of structure.
For solving above-mentioned existing technical matters, the utility model adopts following scheme: self-locking folding base plate oil jack, comprise base, be located at shell on base, establish piston rod in the enclosure, be located at the self lock nut of shell upper, described base both sides are provided with folded sheet.
As preferably, described shell upper port is provided with the top cap being connected with self lock nut, and this structural housing upper port is connected with self lock nut by top cap, and the stability of reinforcement structure is convenient to dismantle.
As preferably, described top cap is provided with outward extending fixture block, and described fixture block is connected in shell upper port, this structure top cap is provided with outward extending fixture block, fixture block is connected in shell upper port, further strengthens the stability that top cap connects, and structure is more firm.
As preferably, on described base, be positioned at shell right side and be provided with the pump housing, the described pump housing is provided with presses hand, is positioned at shell right side and is provided with the pump housing on this pier, and the pump housing is provided with presses hand, and structure is more reasonable, easy to operate.
As preferably, described piston rod sidepiece is equipped with rubber seal, and the rubber seal of this structure piston bar sidepiece is strengthened the sealing effectiveness of piston rod, and Comparision is reliable.
As preferably, between described fixture block bottom and outer shell outer wall, be also provided with sealed nylon circle, between this structure fixture block bottom and outer shell outer wall, be also provided with sealed nylon circle and strengthen the sealing effectiveness between fixture block and shell.
Beneficial effect:
The utility model adopts technique scheme that self-locking folding base plate oil jack is provided, and designs a kind of have auto-lock function and the folding board-like area of thrust surface that increase base, strengthens the stability of structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, self-locking folding base plate oil jack, comprise base 1, be located at the shell 2 on base 1, be located at the piston rod 3 in shell 2, be located at the self lock nut 4 on shell 2 tops, described base 1 both sides are provided with folded sheet 5, described shell 2 upper port are provided with the top cap 6 being connected with self lock nut 4, described top cap 6 is provided with outward extending fixture block 61, described fixture block 61 is connected in shell 2 upper port, on described base 1, be positioned at shell 2 right sides and be provided with the pump housing 7, the described pump housing 7 is provided with presses hand 8, described piston rod 3 sidepieces are equipped with rubber seal 9, between described fixture block 61 bottoms and shell 2 outer walls, be also provided with sealed nylon circle 10.
When real work, this structural housing 2 upper port are connected with self lock nut 4 by top cap 6, strengthen the stability of structure, be convenient to dismounting, structure top cap 6 is provided with outward extending fixture block 61, fixture block 61 is connected in shell 2 upper port, further strengthen the stability that top cap 6 connects, structure is more firm, on pier 1, be positioned at shell 2 right sides and be provided with the pump housing 7, the pump housing 7 is provided with presses hand 8, structure is more reasonable, easy to operate, the rubber seal 9 of structure piston bar 3 sidepieces is strengthened the sealing effectiveness of piston rod 3, Comparision is reliable, between structure fixture block 61 bottoms and shell 2 outer walls, be also provided with sealed nylon circle 10 and strengthen the sealing effectiveness between fixture block 61 and shell 2, the utility model designs a kind of have auto-lock function and the folding board-like area of thrust surface that increase base, strengthen the stability of structure.
Specific embodiment described herein is only to the explanation for example of the utility model spirit, the utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
