Abstract
The utility model relates to the field of manufacturing of engineering vehicles, and in particular discloses a plunger type front top hydraulic cylinder. The plunger type front top hydraulic cylinder comprises a plunger rod (1), an oil inlet (2), an upper mounting base (3), a lower mounting base (4) and a cylinder body which is sealed with the plunger rod (1), wherein the plunger rod (1) is arranged on a bottom frame cross beam by the lower mounting base (4); the cylinder body is arranged on a cargo tank by the upper mounting base (3); and the oil inlet (2) is formed to the plunger rod (1) close to the lower mounting base (4). The plunger type front top hydraulic cylinder has the advantages of simplifying a structure and reducing weight and manufacturing cost along with practicality.
Description
Technical field
The utility model relates to engineering truck and makes the field, is specifically related to a kind of plunger type sinciput oil hydraulic cylinder.
Background technique
At present, known engineering truck is the engineering lorry particularly, used sinciput oil hydraulic cylinder; Be that filler opening is placed outer cylinder body, and on plunger rod, be fixedly connected an outer cover, two installation shaft place respectively on outer cylinder body and the outer cover; Specifically be to adopt the outer cylinder body lower end is installed on the lorry crossbeam through following installation shaft, outer cover is installed on the container through last fitting seat, though reduced the mounting distance between two installation shaft; Made things convenient for installation, but increased the gross weight of oil hydraulic cylinder, increased and manufactured cost.
The model utility content
The utility model has overcome the deficiency of existing technology, and a kind of plunger type sinciput oil hydraulic cylinder is provided, and it is too heavy to have solved existing technology weight, the problem that fabricating cost is big.
For solving above-mentioned technical problem, the utility model adopts following technological scheme:
A kind of plunger type sinciput oil hydraulic cylinder; Comprise plunger rod, filler opening, last fitting seat, following fitting seat; And the cylinder body that seals mutually with plunger rod; Described plunger rod is installed on the body transom through following fitting seat, and described cylinder body is installed on the container through last fitting seat, and described filler opening is arranged on the plunger rod near following fitting seat.
For making the utility model play better technique effect:
Technological scheme further is that above-mentioned cylinder body comprises outer cylinder body and inner cylinder body, is slidingly matched between above-mentioned outer cylinder body and the inner cylinder body.
Technological scheme further is to be slidingly matched between above-mentioned plunger rod and the inner cylinder body.
Technological scheme further is that the joint of above-mentioned cylinder body and last fitting seat is arranged near an end of fitting seat down.
Compared with prior art, the beneficial effect of the utility model is: designs simplification, and weight saving, fabricating cost reduces, and is practical more.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to set forth.
As shown in Figure 1; A kind of plunger type sinciput oil hydraulic cylinder; Comprise plunger rod 1, filler opening 2, go up fitting seat 3, fitting seat 4 down, and the cylinder body that seal mutually with plunger rod 1, described plunger rod 1 is installed on the body transom through fitting seat 4 down; Described cylinder body is installed on the container through last fitting seat 3, and described filler opening 2 is arranged on the plunger rod 1 near following fitting seat 4.In addition, for adapting to flexible distance and tightness, cylinder body comprises outer cylinder body 5 and inner cylinder body 6, is slidingly matched between above-mentioned outer cylinder body 5 and the inner cylinder body 6, is slidingly matched between plunger rod 1 and the inner cylinder body 6;
The joint of cylinder body and last fitting seat 3 is arranged on the sidewall near following fitting seat 4 one ends, makes this hydraulic jack more compact structure.
