Example one

Referring to fig. 1 to 5, the present embodiment provides a case; fig. 1 is a schematic structural diagram of the box body provided in this embodiment, and simply illustrates a relative positional relationship between a door body and a box main body; fig. 2 is a first structural schematic diagram of the tank main body of the tank provided in the embodiment, in which the structure of the tank main body of the tank for accommodating the hydraulic and electric systems is simply shown; FIG. 3 is an enlarged view of a portion of the tank body of FIG. 1 at A, clearly showing the structure of the mounting slot; fig. 4 is a second structural schematic diagram of the tank main body of the tank provided in the embodiment, in which the structure of the tank main body of the tank for accommodating the engine system is simply shown; fig. 5 is a schematic structural view of the tank main body in fig. 3 at B, clearly showing the structure of the first through hole and the second through hole.

Referring to fig. 1 to 5, in the case 1 provided in the present embodiment, the case 1 is used for a scissor lift platform, and the case 1 includes a case main body 11, a door body 10, and a telescopic member.

The door body 10 is hinged with the box main body 11, and two ends of the telescopic member are respectively hinged with the door body 10 and the box main body 11; the telescopic member can be extended or shortened in the longitudinal direction thereof to pivot the door body 10 by a predetermined angle with respect to the box main body 11, and further correspondingly open the box main body 11 or close the box main body 11 through the door body 10.

Optionally, the telescopic member is a gas spring, a hydraulic cylinder or an electric push rod. Taking the gas spring as an example, a cylinder body of the gas spring is hinged to the tank main body 11, and a cylinder rod of the gas spring is hinged to the door body 10, so that as the cylinder rod extends out of the cylinder body, the door body 10 pivots forward relative to the tank main body 11 and gradually opens the tank main body 11, and as the cylinder rod retracts into the cylinder body, the door body 10 pivots backward relative to the tank main body 11 and gradually closes the tank main body 11. The telescopic member is an air spring, so that the reasonability and controllability of the opening and closing stress of the door body 10 can be improved, and the cost can be reduced.

Optionally, the cabinet 1 further includes a hood lock 131, and the hood lock 131 includes a first lock portion and a second lock portion that can be locked by a key, the first lock portion is provided on the cabinet body 11, and the second lock portion is provided on the door 10.

The cabinet 1 in this embodiment includes an extensible member, and a door 10 and a cabinet body 11 hinged to each other by the extensible member. By extending or shortening the telescopic member, the door body 10 can be pivoted with respect to the box main body 11, and the box main body 11 can be automatically opened or closed. The degree of opening or closing of the box main body 11 can be correspondingly controlled by controlling the degree of extension or shortening of the telescopic member, and the door body 10 is kept at a preset opening degree, so that a worker does not need to manually fix the door body 10, and the convenience of maintenance and overhaul is improved; by controlling the speed of extension or contraction of the telescopic member, the opening or closing speed of the box main body 11 can be correspondingly controlled, thereby being beneficial to improving the flexibility, controllability and rationality of opening and closing the door body 10.

In this state, that is, in a normal operating state or a non-maintenance state, the expansion and contraction member does not actively expand or contract so that the door body 10 is held at a position where the box main body 11 is closed. By positioning the pivot axis of the door 10 relative to the box body 11 on the side of the first connection line close to the door 10, if the door 10 pivots in the positive direction relative to the box body 11 due to vehicle bumping or the like, the first connection line will move, and the pivot axis of the door 10 relative to the box body 11 will pass through the first connection line, in this case, the system composed of the door 10, the box body 11 and the telescopic member is in the dead point position, and the door 10 cannot be opened any more, so as to avoid the risk of the door 10 being opened by mistake in the normal working state or non-maintenance state of the box body 1.

Alternatively, a connecting member is provided on a surface of the mounting plate 110 facing away from the door body 10, so that the mounting plate 110 is connected with other components of the scissors lifting platform through the connecting member, so that the box body 1 is disposed at a side portion of the scissors lifting platform, in which case the box body 1 serves as a side box. However, without being limited thereto, in an alternative embodiment, the box body 1 may also be provided at the back of the scissor lift platform to serve as a back box according to design requirements.

Alternatively, the first locking portion is disposed on a side edge portion of the fourth plate 116 away from the mounting plate 110, and the second locking portion is disposed on a side edge portion of the door body 10 away from the second plate 113.

Alternatively, in order to ensure that the door body 10 can sufficiently open the box main body 11, the predetermined angle is an angle corresponding to the angle at which the door body 10 can be pivoted to be located entirely on the side of the second plate 113 facing away from the fourth plate 116.

In an alternative of the present embodiment, in a state where the third space 119 is used to house the engine system, the first inclined plate portion 111, the second inclined plate portion 112, the third inclined plate portion 114, and the fourth inclined plate portion 115 are each provided with reinforcing ribs 128 that are staggered in the longitudinal and transverse directions. On the other hand, the structural strength of the first plate and the second plate 113 can be improved, and the structural strength of the entire box main body 11 can be further improved. On the other hand, the provision of the reinforcing ribs 128 before the first and second plates 113 are molded is also advantageous in reducing the difficulty of machining the first plate into the shape in which the first inclined plate portion 111 and the second inclined plate portion 112 are connected by machining, and in reducing the difficulty of machining the second plate 113 into the shape in which the third inclined plate portion 114 and the fourth inclined plate portion 115 are connected by the frame.

The aperture of the second through hole 121 is smaller than that of the first through hole 120, so that in the secondary ventilation structure, sundries such as fallen leaves and the like entering the first space 117 and the second space 118 from the first through hole 120 are prevented from entering the third space 119 through the second through hole 121, the cleanness degree in the third space 119 can be effectively improved, and the influence of sundries such as fallen leaves on the normal work of an engine system or a hydraulic and electric system is avoided.
