Abstract
The utility model discloses a piston rod. The piston rod comprises a piston rod body (1), a pressure spring (4) and a buffer block (3), wherein one end of the piston rod body (1) comprises a groove (2) and a fixed sheet (5) connected with the groove (2); the buffer block (3) is mounted in the groove (2) and can move; and one end of the pressure spring (4) is connected with the bottom surface of the groove (2) and the other end of the pressure spring (4) is connected with the back surface of the buffer block (3). The piston rod is provided with the pressure spring, so that the impact force in the piston rod direction is greatly reduced, the piston rod is difficult to deform and damage by the impact force and the service life of the piston rod is prolonged.
Description
Technical field
The utility model relates to the hydraulic jack accessory, particularly a kind of piston rod.
Background technique
Piston rod in the existing hydraulic jack is when acting, and the piston that is connected with piston rod contacts for very stiff and demanding with cylinder body, because piston rod is generally more elongated, so the easy stress deformation of piston rod damages, causes the piston rod life-span to be reduced.
The model utility content
The technical problem that (one) will solve
The technical problems to be solved in the utility model is will solve the piston that is connected with piston rod to contact with cylinder body is very stiff and demanding, easily the problem of the easy stress deformation of piston rod.
(2) technological scheme
For addressing the above problem, piston rod of the present utility model comprises piston rod body, stage clip and buffer stopper; One end of described piston rod body includes groove and the fixed plate that is connected with groove, and described buffer stopper is installed in the groove movable, the bottom surface of described stage clip one end connecting groove, and the other end links to each other with the buffer stopper back side.The utility model greatly reduces the impulse force of piston rod direction by stage clip is set, and buffer stopper can be connected with piston, makes piston rod not be subject to the impulse force deformed damaged, has prolonged the working life of piston rod.
In the above-mentioned piston rod, described buffer stopper includes outer step, and described outer step is arranged in the groove.
(3) beneficial effect
Piston rod of the present utility model greatly reduces the impulse force of piston rod direction by stage clip is set, and makes piston rod not be subject to the impulse force deformed damaged, has prolonged the working life of piston rod.
Description of drawings
Fig. 1 is the structural representation of piston rod of the present utility model;
1 is that piston rod body, 2 is that groove, 3 is that buffer stopper, 4 is that stage clip, 5 is that fixed plate, 6 is outer step among the figure.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, piston rod of the present utility model comprises piston rod body 1, stage clip 4 and buffer stopper 3; One end of described piston rod body 1 includes groove 2 and the fixed plate 5 that is connected with groove 2, it is interior movable that described buffer stopper 3 is installed in groove 2, the bottom surface of described stage clip 4 one end connecting grooves 2, the other end links to each other with buffer stopper 3 back sides, described buffer stopper 3 includes outer step 6, and described outer step 6 is arranged in the groove 2.Described buffer stopper 3 can be connected with piston, and described stage clip 4 can reduce the impulse force of piston rod direction, makes piston rod not be subject to the impulse force deformed damaged, has prolonged the working life of piston rod.
During piston rod work of the present utility model, piston rod moves down, after the piston that links to each other with buffer stopper 3 moves to the end, described piston and buffer stopper 3 maintain static, described piston rod body 1 still continues mobile, but be subject to the resistance of stage clip 4, made piston rod body travelling speed slack-off, thereby cushioned the impulse force of piston rod body 1.
Piston rod of the present utility model greatly reduces the impulse force of piston rod direction by stage clip is set, and makes piston rod not be subject to the impulse force deformed damaged, has prolonged the working life of piston rod.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (2)
1. a piston rod is characterized in that, described piston rod comprises piston rod body (1), stage clip (4) and buffer stopper (3); One end of described piston rod body (1) includes groove (2) and the fixed plate (5) that is connected with groove (2), described buffer stopper (3) is installed in the groove (2) movable, the bottom surface of described stage clip (4) one end connecting grooves (2), the other end links to each other with buffer stopper (3) back side.
2. piston rod according to claim 1 is characterized in that, described buffer stopper (3) includes outer step (6), and described outer step (6) is arranged in the groove (2).
