Description

Technical Field

[0001] The utility model relates to a toolbox, in particular to a toolbox for overhauling a logistics vehicle, and belongs to the technical field of design and manufacture of overhauling equipment or tools. Background Art

[0002] A logistics vehicle is an important transportation device in industrial production. To ensure the safe driving of the logistics vehicle, maintenance personnel need to regularly overhaul and maintain it. Different types and styles of tools are used in the whole overhaul and maintenance process. The maintenance personnel can place these tools in a special maintenance toolbox, take out the tools from the box when in use, and put them back into the box when not in use. Most of the existing toolboxes adopt an integral structure, and there is a lack of a mechanism for classifying and storing overhaul tools inside, resulting in various tools being mixed together and not being easily retrieved quickly. In addition, since most tools are made of iron or steel, when the environment is humid or the tools are wet, a sealed humid space will be formed inside the toolbox, causing the tools to rust and thus affecting the normal use of the tools. Therefore, it is necessary to improve the existing technology. Summary of the Invention

[0003] To solve the problems existing in the existing toolbox during use, such as easy rusting of tools, inconvenient use, and single function, the utility model provides a toolbox for overhauling a logistics vehicle.

[0004] The utility model is completed through the following technical solutions: A toolbox for overhauling a logistics vehicle includes a box body, which is characterized in that the box body is provided with a plurality of layers stacked from bottom to top. A swing opening mechanism is provided between the upper and lower box bodies. A sealing cover is provided on the top-layer box body. A lifting mechanism is provided in the bottom-layer box body. Among them, a sealing component is provided around the side edge of the sealing cover. A one-way valve and a locking mechanism are provided on the sealing cover, so as to place and store various tools through the multi-layer box body. The top-layer box body can form a sealed space under the sealing of the sealing cover, so as to store tools and parts that are easy to rust. Through the lifting mechanism, the box body can be raised when needed or taken out for use as a climbing pedal.

[0005] The plurality of box bodies are provided as rectangular bodies with openings at the top, and are symmetrically arranged in three layers from bottom to top. A vertical partition extending upward is provided in the middle of the bottom-layer box body. The box bodies above the bottom layer are respectively arranged on both sides of the vertical partition, and the cross-sectional size of the upper-layer box body is adapted to the cross-sectional size of the lower-layer box body separated by the vertical partition. A handle is hinged to the top of the vertical partition through a hinge shaft, so as to classify and place tools and parts through the multi-layer box body.

[0006] The swing opening mechanism includes: swing rod groups respectively arranged on both sides of the three-layer box body. Two groups are symmetrically arranged on each side of the swing rod group. Each group of swing rods includes: an upper swing rod whose two ends are respectively hinged to the first and second layer box bodies through hinge shafts, a lower swing rod whose two ends are respectively hinged to the second and third layer box bodies through hinge shafts, and a middle swing rod whose two ends and the middle are respectively hinged to the first, second, and third layer box bodies through hinge shafts. Moreover, the lengths of the upper and lower swing rods are both smaller than the length of the middle swing rod, so that when the multi-layer box body is in use, the swing rod group can make it extend outwards in a stepped shape to facilitate taking and placing tools, and when it is stored, it can be stacked and closed inward in sequence.

[0007] The lifting mechanism is arranged in the concave cavity at the bottom of the bottom layer box body. The lifting mechanism includes a base, a pedal arranged above the base. A scissor lifting assembly and a power cylinder are arranged between the base and the pedal. The two sides of the pedal are provided with outwardly protruding edges, and the protruding edges are slidably matched with the sliding grooves arranged on both sides of the concave cavity. One end of the concave cavity is set as an open end, so that the lifting mechanism can be slid out through the open end for use when climbing to a height, or slid into the box body for storage, and the box body can also be lifted to facilitate taking tools.

[0008] The sealing cover is arranged at the open top of the top layer box body. It is set as a rectangular flat plate adapted to the shape of the open top of the box body. A handle is arranged on the top surface of the rectangular flat plate, so that the top layer box body can be closed through the sealing cover.

[0009] The one-way valve includes a valve body with a valve core arranged inside. The valve body is arranged on the sealing cover. The inlet end of the valve body is connected to the ventilation hole arranged on the sealing cover, and the outlet end of the valve body is connected to the outside. So that after the sealing cover is covered, the air in the top layer box body can be discharged through the one-way valve, and a closed space is formed inside the box body to prevent tools from rusting.

[0010] The sealing component includes a strip-shaped airbag arranged around the side of the sealing cover, a moisture-absorbing strip arranged below the strip-shaped airbag and also arranged around the side of the sealing cover. A plurality of air inlet holes communicating with the strip-shaped airbag are arranged on the bottom surface of the sealing cover. So that when the sealing cover is covered, the gas generated by pressing down can enter the strip-shaped airbag through the air inlet holes, and the strip-shaped airbag expands, thereby closing the gap between the sealing cover and the open top of the box body, ensuring that a closed space can be formed inside the box body to prevent moisture from entering the box body. The moisture-absorbing strip can prevent external moisture from entering the box body, and at the same time can absorb the moisture inside the box body.

[0011] The locking mechanism includes knobs provided on both sides of the top surface of the sealing cover. The rotating shaft of each knob passes through the sealing cover and is connected to one end of a swing arm provided on the bottom surface of the sealing cover. The other end of the swing arm is fitted with a longitudinal chute on a sliding plate provided on the bottom surface of the sealing cover through a pin shaft. The sliding plate is slidably connected to a transverse chute provided on the bottom surface of the sealing cover through an end slider. Both sides of the sliding plate are respectively hinged to one end of an L-shaped pendulum. The corner of the L-shaped pendulum is hinged to the bottom surface of the sealing cover through a hinge shaft. The other end of the L-shaped pendulum is hinged to the inner end of a translation rod. A magnet is provided at the outer end of the translation rod, and limiting blocks that slidably fit therewith are provided on both sides of the translation rod. So when the knob is rotated, the swing arm drives the sliding plate to reciprocate along the transverse chute, and the laterally moving sliding plate drives the L-shaped pendulum to swing around the swing shaft, thereby driving the translation rod to extend outwards along the limiting blocks. When the outer end magnet attracts the inner wall of the box body, the locking of the sealing cover is completed. When the translation rod retracts, the outer end magnet disengages from the inner wall of the box body, and the sealing cover is opened accordingly.

[0012] The utility model has the following advantages and effects:

[0013] 1. By placing the rust-prone tools in the top layer of the box body, a sealed space can be formed inside the box body through the sealing cover, thus avoiding the rust problem caused by the contact between the tools and external moisture. The strip-shaped airbag and moisture-absorbing strip on the sealing cover can further ensure that external moisture does not enter the box body, and at the same time can also absorb the residual moisture inside the box body;

[0014] 2. The lifting pedal provided at the bottom of the box body can be taken out when needed for personnel to climb, or to raise the height of the box body to facilitate the access to tools and improve work efficiency. Description of the Drawings
