Abstract
The utility model relates to a plastic oil tank. A plurality of threaded holes are formed in the connecting surface of a tank body which is a symmetric body and a pump body, the circle centers of the threaded holes are positioned on a symmetric axis, and the circle center of at least one threaded hole is not positioned on the symmetric axis. The quantity of residual oil in the plastic tank body which is molded through injection can be directly observed. At least one threaded hole which is deviated from the symmetric center is formed in the external connecting surface, and the adoption of an asymmetric threaded hole structure is convenient for assembly and correction. The defects, such as blow holes, sand inclusion hard points and the like, of an original cast aluminum oil tank are overcome, the weight of the oil tank is reduced, and the cost is lowered. Besides, the plastic molding performance is great, specially shaped oil tanks can be designed to meet the space requirements of different work conditions, the structure is simple, and the practicability is strong.
Description
Technical field
The utility model relates to a kind of long-pending oil tank that vehicle-mounted integrated hydraulic system is used.
Background technique
The long-pending oil tank that vehicle-mounted hydraulic system is used is at present used aluminum casting mostly, has the defects such as pore, burning into sand hard spot, and is difficult for observing Fuel Oil Remaining in oil tank, and sealing is poor simultaneously, cost is high.
Model utility content
The purpose of this utility model is to propose a kind of plastic oil tank for the deficiency existing in above-mentioned background technology, in order to solve the deficiencies in the prior art.
The technical solution adopted in the utility model is: a kind of plastic oil tank, it is characterized in that: the plastic container that is included as symmetric body, on the junction surface of tank body and the pump housing, be provided with a plurality of tapped holes, the center of circle of described tapped hole is positioned on symmetry axis, and has the center of circle of a tapped hole at least not on described symmetry axis.
Preferably, on being provided with the inwall of tapped hole, described tank body is provided with the first stiffening rib.
Preferably, in described tapped hole, be embedded with copper nut.
Preferably, when described tank body is non-rotary body, on the inwall of tank body edges and corners, be provided with the second stiffening rib.
The beneficial effects of the utility model are: the plastic container of molding and forming, the Fuel Oil Remaining inside the Pass can observing directly, is externally at least provided with a tapped hole on junction surface and symmetry center is provided with offset distance, adopts asymmetrical thread pore structure, is convenient to assemble centering.Not only overcome the defects such as original cast aluminium oil tank pore, burning into sand hard spot, and alleviated oil tank weight, reduced cost.In addition, plastic shaping performance is good, can design special-shaped oil tank to meet the spatial requirement of different operating modes, simple in structure, practical.

Embodiment
As shown in Figure 1, a kind of plastic oil tank, oil tank body 1 is tightly connected with the pump housing 2.
As shown in Figures 2 and 3, described tank body 1 is symmetric body, on the junction surface of tank body 1 and the pump housing 2, be provided with a plurality of and center of circle and be positioned at the first tapped hole 3 on symmetry axis, and be at least provided with second tapped hole 4, on the no longer above-mentioned symmetry axis in the center of circle of described the second tapped hole 4, the center of circle of the second tapped hole 4 and above-mentioned symmetry axis are provided with offset distance, are convenient to like this assemble centering.At described tank body 1, be provided with on the inwall of the first tapped hole 3 and the second tapped hole 4 and be provided with the first stiffening rib 5, improve the intensity of oil tank.When described tank body is non-rotary body, on the inwall of the non-rotary body tank body edges and corners as in Fig. 2 and Fig. 3, be provided with the second stiffening rib 6.
As shown in Figure 4, in the first tapped hole 3, be embedded with copper nut 7, in the second tapped hole 4, be embedded with equally copper nut 7, therefore its structure and the consistent accompanying drawing of separately not doing of copper nut 7 structures in the first tapped hole 3 have so just improved the reliability connecting.
