Abstract
The utility model relates to a fuel tank cap capable of being opened through bidirectional pressure control. The fuel tank cap comprises a cap top, a cap body, a joint, a sealing fin, an adjustment sheet, a large spring, a compressing piece, a small spring, a contact and a seal ring, wherein the cap top is clamped on the cap body, the joint, the sealing fin, the adjustment sheet, the large spring and the compressing piece are sequentially connected from top to bottom, the compressing piece is installed on the middle lower portion of the cap body, the small spring is compressed on the contact, the contact is connected with the joint, and the seal ring is arranged on the cap body in a sleeved mode. The fuel tank cap capable of being opened through the bidirectional pressure control has the advantages that under the situation that sealing of a fuel tank is guaranteed, pressure inside the fuel tank is regulated, and the security coefficient of the fuel tank is improved.
Description
Technical field
The utility model relates to a kind of fork truck, relates in particular to a kind of fork truck with two-way voltage-controlled unlatching fuel lid.
Background technology
At present, in the fork truck technical field, the fuel tank of fork truck generally all adopts the closed oil case lid.And the effect of closed oil case lid alternates betwwen good and bad, and fuel tank, when the rising of hydraulic efficiency pressure system temperature, causes its internal pressure excessive in the process of using, then cause the generation of Peril Incident; The consumption of fuel oil in fuel tank causes the pressure of fuel tank too small, and while forming negative pressure, the oil suction Efficiency Decreasing of driving engine, finally cause suction not oil, and affects the work efficiency of fork truck.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of fork truck with two-way voltage-controlled unlatching fuel lid, pressure that again can regulating oil tank inside when guaranteeing leak tightness, improve safety factor that fuel tank uses and the work efficiency of fork truck.
The utility model is that the technical scheme that the problem of the above-mentioned proposition of solution adopts is:
A kind of fork truck, with two-way voltage-controlled unlatching fuel lid, comprises caping 1, lid body 2, joint 3, seal strip 4, adjustment sheet 5, big spring 6, compressing tablet 7, little spring 8, contact 9 and seal ring 10, caping 1 are stuck in and cover on body 2, and joint 3, seal strip 4, adjustment sheet 5, big spring 6, compressing tablet 7 are connected from top to bottom successively, compressing tablet 7 is arranged on and covers body 2 middle and lower parts, little spring 8 is pressed on contact 9, and above contact 9, joint 3, and seal ring 10 is enclosed within and covers on body 2.
Press such scheme, circular chuck 11 is set below described lid body 2, convenient card is withheld sheet 7.
Press such scheme, described compressing tablet 7 and be provided with projection above contact 9, be used for the spring location.
Press such scheme, described joint 3 is the tee T joint, make the sealing of fuel tank stressed evenly, convenient sealing.
Press such scheme, two protruding rings are set on described seal strip 4, increased the leak tightness of fuel tank.
Principle of work of the present utility model: excessive when tank internal pressure, contact moves squeezed joint, exposes the gap pressure release; When the too small formation negative pressure of tank internal pressure, adjustment sheet moves and makes the extraneous gas supercharging of coming in, when internal pressure is at equilibrium, and the sealing of adjustment sheet return, thereby the pressure of regulating oil tank inside.
The beneficial effects of the utility model are:, in the situation that guarantee the internal pressure of fuel tank sealing regulating oil tank, improved the safety factor of fuel tank.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, the 1-caping, 2-covers body, 3-joint, 4-seal strip, 5-adjustment sheet, 6-big spring, 7-compressing tablet, 8-little spring, 9-contact, 10-seal ring, the circular chuck of 11-.
The specific embodiment
Further illustrate embodiment of the present utility model below in conjunction with accompanying drawing.
With reference to Fig. 1, the described a kind of fork truck of this specific embodiment, with two-way voltage-controlled unlatching fuel lid, comprises caping 1, lid body 2, joint 3, seal strip 4, adjustment sheet 5, big spring 6, compressing tablet 7, little spring 8, contact 9 and seal ring 10, caping 1 are stuck in and cover on body 2, joint 3, seal strip 4, adjustment sheet 5, big spring 6, compressing tablet 7 are connected from top to bottom successively, and compressing tablet 7 is arranged on and covers body 2 middle and lower parts, and little spring 8 is pressed on contact 9, above contact 9, joint 3, and seal ring 10 is enclosed within and covers on body 2.
Described compressing tablet 7 and contact 9 are provided with projection, are used for the spring location.
Described joint 3 is the tee T joint, make the sealing of fuel tank stressed evenly, convenient sealing.
Two protruding rings are set on described seal strip 4, have increased the leak tightness of fuel tank.
The principle of work of this specific embodiment: excessive when tank internal pressure, contact moves squeezed joint, exposes the gap pressure release; When the too small formation negative pressure of tank internal pressure, adjustment sheet moves and makes the extraneous gas supercharging of coming in, when internal pressure is at equilibrium, and the sealing of adjustment sheet return, thereby the pressure of regulating oil tank inside.
The beneficial effect of this specific embodiment is:, in the situation that guarantee the internal pressure of fuel tank sealing regulating oil tank, improved the safety factor of fuel tank.
The above; be only preferred embodiment of the present utility model, not the utility model done any pro forma restriction, those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification; equivalent variations or modification, all drop in protection domain of the present utility model.
