Description

Engineering machinery oil tank protection device

Technical Field

The utility model belongs to an auxiliary mechanism on engineering machinery, and particularly relates to an oil tank protection device of the engineering machinery.

Background

The oil tank of the existing engineering machinery mainly has two structures, one is that the oil tank cover is provided with a lock, but the lock needs to specially develop a mould, so that the production cost is higher; the other is that the fuel tank cover is not provided with a fuel tank lock, which causes the fuel tank to have lower prevention risk capability, namely the risk of artificially adding non-oil substances into the fuel tank or stealing fuel exists. At present, no engineering machinery oil tank protection device which is strong in universality, convenient to process and low in production cost exists.

Disclosure of Invention

The technical problem to be solved by the utility model is as follows: the engineering machinery oil tank protection device is simple in structure, low in cost, convenient to use and capable of well preventing risks.

Engineering machine tool oil tank protector, including fixed plate and clamp plate, the fixed plate is articulated with the clamp plate upper end, the clamp plate lower extreme offsets with the fuel tank cap, lie in the both sides of articulated department on the clamp plate and be equipped with the lockhole one of more than one equidistance respectively, the one end of keeping away from the clamp plate on the fixed plate is equipped with and lockhole one matched with lockhole two.

Preferably, hinge holes are respectively formed in the fixed plate and the pressing plate, a hinge pin is arranged in each hinge hole, a boss is arranged at one end of each hinge pin, the outer contour of each boss is larger than the diameter of each hinge hole, and the other end of each hinge pin is fixedly connected with the fixed plate or the pressing plate.

Preferably, the pressing plate is of an L-shaped structure.

Preferably, a lock is arranged in the first lock hole and the second lock hole matched with the first lock hole.

Compared with the prior art, the utility model has the beneficial effects that:

1. the utility model has simple structure, the fixed plate and the pressing plate can be directly formed by stamping, the processing and the manufacturing are convenient, the universality is strong, and the cost is lower;

2. one end of the pin shaft is welded with the pressing plate or the fixing plate, so that the pin shaft is firmer and is not easy to fall off and lose;

3. the relative pivoted two holes equidistance of round pin axle is followed to the clamp plate, can switch the state of locking and opening in a flexible way, has effectively increased and has resisted the risk ability to effectively protect fluid.

FIG. 2 is a second schematic structural view of the present invention;

FIG. 3 is a schematic structural diagram of the present invention during locking;

FIG. 4 is a schematic view of the present invention in an open configuration.

In the figure, 1, a pressure plate; 2. a first lock hole; 3. a pin shaft; 4. a fixing plate; 5. a second lock hole; 6. locking; 7. a fuel tank cap; 8. a vehicle frame.

Detailed Description

The utility model will be further described with reference to the accompanying drawings in which:

the first embodiment is as follows: as shown in fig. 1 and 2, the engineering machinery oil tank protection device comprises a fixing plate 4 and a pressing plate 1, wherein the fixing plate 4 is hinged to the upper end of the pressing plate 1, the fixing plate 4 is welded and fixed to a vehicle frame, the lower end of the pressing plate 1 abuts against an oil tank cover 7, two sides of the hinged position of the pressing plate 1 are respectively provided with a first locking hole 2 in an equal distance, the first locking holes 2 on the two sides can be one or multiple, and one end, far away from the pressing plate 1, of the fixing plate 4 is provided with a second locking hole 5 matched with the first locking hole 2. When the user uses, can be equipped with corresponding oil tank protection lock by oneself, during the use, support oil tank cap 7 through clamp plate 1, reuse lock pins with its matched with lockhole 2 with lockhole two 5 of keeping away from 1 one end of clamp plate on the fixed plate 4, realizes the locking of oil tank cap 7, at this moment, can't open oil tank cap 7.

The fixed plate 4 and the pressing plate 1 are respectively provided with a hinge hole, a hinge pin 3 is arranged in the hinge hole, one end of the hinge pin 3 is provided with a boss, the outer contour of the boss is larger than the diameter of the hinge hole, and the other end of the hinge pin 3 is fixedly connected with the pressing plate 1. The other end of the pin shaft 3 is fixed with the pressing plate 1, so that the fixed plate 4 is prevented from being separated from the pressing plate 1 at the hinged position and being lost, and the use is convenient.

Example two: the pin shaft 3 is fixedly connected with the fixing plate 4; the rest is the same as the first embodiment.

Example three: a lock 6 is arranged in the lock hole II 5 matched with the lock hole I2; the other steps are the same as those in the first or second embodiment.

According to the utility model, the pressing plate 1 is of an L-shaped structure, so that the pressing plate 1 of the L-shaped structure is more material-saving and has a better locking effect.

As shown in fig. 3, when the oil tank cover is used, the pressure plate 1 is rotated downwards along the pin shaft 3, at the moment, the lower end of the pressure plate 1 abuts against the oil tank cover 7, the fixing plate 4 and the pressure plate 1 are locked by the lock 6, and the oil tank cover 7 can be locked, so that the oil tank can be protected; as shown in figure 4, when the oil tank needs to be opened, the lock 6 is opened, the pressing plate 1 is rotated upwards, the second locking hole 5 in the fixing plate 4 is matched with the first locking hole 2 at the other end of the pressing plate 1, at the moment, the pressing plate 1 is separated from the oil tank cover 7, the oil tank can be subjected to filter element replacement, and the use is convenient.
