Abstract
The utility model discloses an adjusting sleeve for a forklift tilt cylinder. The adjusting sleeve is sheathed on a piston rod; at least one ring-shaped groove is arranged on the inner ring wall in the adjusting sleeve, and the inner ring wall in the adjusting sleeve is contacted with the piston rod; the groove is internally provided with an O-shaped ring; the O-shaped ring is limited by the groove. After the adjusting sleeve provided with the O-shaped ring is assembled on the piston rod, the vibration caused by the movement of the tilt cylinder can be reduced by the elasticity of rubber, the deformation of the rubber can be restored, and the sliding of the tilt cylinder can be prevented. The adjusting sleeve has the beneficial effects that the sliding of the adjusting sleeve for the tilt cylinder can be reduced; the abrasion of the piston rod caused by the sliding of the adjusting sleeve for the tilt cylinder can be reduced.
Description
Technical field
The utility model belongs to fork truck accessory field, is specifically related to a kind of adjusting sleeve for tilting oil cylinder of fork.
Background technology
Tilting oil cylinder of fork is fork truck important composition parts, controls the anteversion and retroversion of door frame; The inclination angle, front and back of dump ram is according to the difference of operating mode, and before and after requiring, inclination angle is also different, and the variation requirement that adjusting sleeve realizes angle is generally installed on piston rod.Under heeling condition, the partical gravity that adjusting sleeve produces along piston rod direction, makes adjusting sleeve have the trend of downslide.In order to stop the downslide of adjusting sleeve, as shown in Figure 3, existing method is, in adjusting sleeve 2, beats tapped bore, and by screw 8 extruding stoppers 7, stopper 7 extrusion piston bars 4 produce friction force and stop adjusting sleeves 2 to glide.This method can reach expected effect within certain time limit, but because fork truck is forward and backward frequently, incline, under hypsokinesis effect, bear very strong impulsive force especially, easily make screw occur loosening, and the squeese pressure deficiency of stopper causes adjusting sleeve slip, worn piston bar.
Utility model content
For overcoming the defect that dump ram adjusting sleeve of the prior art is slided and dump ram adjusting sleeve is slided to piston rod wearing and tearing, the utility model provides a kind of adjusting sleeve for tilting oil cylinder of fork.
Concrete technical scheme of the present utility model is as follows:
For an adjusting sleeve for tilting oil cylinder of fork, described adjusting sleeve 2 is set on a piston rod 4; The inner internal ring wall contacting with described piston rod 4 of described adjusting sleeve 2 is provided with at least one annular groove 6, is provided with O type circle 3 in described groove 6.
Described O type circle 3 adopts quality of rubber materials to make.
In described adjusting sleeve 2, be provided with two grooves 6.
The beneficial effects of the utility model are:
(1) reduce the slip of dump ram adjusting sleeve;
(2) reduce the wearing and tearing that dump ram adjusting sleeve is slided to piston rod.
Accompanying drawing explanation
Fig. 1 is the utility model adjusting sleeve scheme of installation.
Fig. 2 is the utility model adjusting sleeve cutaway view.
Fig. 3 is the scheme of installation of existing adjusting sleeve.
In upper figure, sequence number is: 1-earrings, 2-adjusting sleeve, 3-O type circle, 4-piston rod, 5-cylinder body, 6-groove, 7-stopper, 8-screw.
the specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described further.
Embodiment:
As shown in Figure 1, a kind of adjusting sleeve for tilting oil cylinder of fork, this adjusting sleeve 2 is set on a piston rod 4, and the inner internal ring wall contacting with piston rod 4 of adjusting sleeve 2 is provided with at least one annular groove 6, sees Fig. 2.In this groove 6, be provided with O type circle 3,3 position-limiting actions of 6 pairs of O type circles of groove.In the present embodiment, O type circle 3 adopts quality of rubber materials to make, after the adjusting sleeve 2 that O type circle 3 is installed is assembled on piston rod 4, and the vibration that the elastic performance of rubber produces in the time of can reducing dump ram motion, the distortion restorability of rubber, can prevent the slip of dump ram simultaneously.
In order to reach better anti-skidding and anti-wear effect, in the present embodiment, in adjusting sleeve 2, be provided with two grooves 6, but be not limited to this, the quantity of groove 6 can be adjusted according to the length of adjusting sleeve 2 and piston rod 4.
Using method of the present utility model and principle of work are as follows:
As shown in Figure 1, the adjusting sleeve 2 that inside is provided with to O type circle 3 is set on the piston rod 4 of cylinder body 5, and the other end that adjusting sleeve 2 is corresponding with cylinder body 5 is connected with earrings 1.
When door frame leans forward, piston rod 4 travels forward (in Fig. 1 to left movement), and earrings 1, adjusting sleeve 2 travel forward with piston rod 4.When door frame hypsokinesis, piston rod 4 moves (in Fig. 1, moving right) backward, and earrings 1, adjusting sleeve 2 are moved backward with piston rod 4, until adjusting sleeve 2 contacts with the front end face of cylinder body 5.2 position-limiting actions of adjusting sleeve, by the length of adjusting sleeve 2, the stroke of control plunger bar 4, the angle of inclination of adjustment door frame.
The utility model adds O type circle 3 in the inside of adjusting sleeve 2, utilize the friction force between O type circle 3 and piston rod 4, can effectively reduce adjusting sleeve 2 with respect to the slip of piston rod 4, thereby reduces the wearing and tearing that adjusting sleeve 2 is slided to piston rod 4.And be different from available technology adopting stopper 7 and screw 8, O type circle 3 is arranged in groove 6, be difficult for occurring loosening or displacement, there is better anti-skidding and anti-wear effect.After long-time use, even if the skidproof effect of O type circle 3 reduces, the slip of adjusting sleeve 2 also can not cause the wearing and tearing of piston rod 4, can change in time O type circle 3, and repair and replacement are convenient.For increasing the service life, O type circle 3 can adopt the quality of rubber materials with excellent wear to make.
Disclosed is above only the application's a specific embodiment, but the application is not limited thereto, and the changes that any person skilled in the art can think of, all should drop in the application's protection domain.
