Description

Technical Field

[0001] This utility model relates to the field of semi-trailer technology, and in particular to a pallet box with a concealed door panel. Background Technology

[0002] A semi-trailer is a type of truck consisting of a cab and a cargo box, widely used in logistics, construction sites, and other fields, capable of carrying various goods and heavy equipment. The chassis of a box semi-trailer has a large, flat space underneath, and to improve space utilization, multiple toolboxes, pallet boxes, and other storage compartments are typically installed at the bottom of the chassis. Currently, the pallet box doors are hinged, requiring them to be flipped upwards and secured with ropes to facilitate forklift loading of pallets. However, due to space constraints at the bottom of the chassis, the flipped doors hinder forklift access to the box for pallet loading and unloading, significantly impacting logistics efficiency. Therefore, designing a simpler structure that avoids hindering forklift access for pallet loading and unloading is a crucial technical problem that needs to be solved in this case. Utility Model Content

[0003] To address the above problems, this utility model provides a pallet box with a cleverly designed, efficient, and easy-to-use hidden door panel that improves the forklift's ability to get close to the box for pallet loading and unloading.

[0004] The technical solution of this utility model is:

[0005] The tray box with concealed door panels includes:

[0006] The housing is fixedly installed at the bottom of the vehicle frame, and a receiving cavity is provided between the housing and the vehicle frame; the side of the housing is provided with an opening;

[0007] At least one pair of guide rails are provided, which are detachably and symmetrically fixed on the side of the box and near the top of the box; the guide rails are provided with inclined slides.

[0008] The door is located at the opening; after the door is opened, it slides through the slide rail into the receiving cavity at the top of the box.

[0009] Specifically, a pair of symmetrically fixed V-shaped plates are provided on the side of the box door near the rear end;

[0010] The V-shaped plate is provided with a hinged slide bar, which is confined within the slide rail.

[0011] Specifically, the slide rod is provided with a pair of bearings that are fixedly sleeved at intervals;

[0012] A pair of bearings are respectively disposed on the side of the guide rail frame.

[0013] Specifically, the front end of the slide is provided with a downwardly inclined barb groove.

[0014] Specifically, the bottom of the cabinet door is provided with a fixedly connected handle.

[0015] Specifically, the bottom of the compartment door is detachably and fixedly connected to the compartment body via a compartment lock.

[0016] Specifically, the box contains a storage area;

[0017] The bottom of the storage area is provided with a fixedly connected corrugated metal plate.

[0018] Specifically, the box body has two openings, which are arranged opposite each other.

[0019] Specifically, the middle part of the box is provided with a detachable and fixedly connected partition.

[0020] Specifically, the door of the box is provided with folded edges around its perimeter.

[0021] This utility model includes a box body, a guide rail frame, and a box door; the box door is slidably mounted on the guide rail frame, which has an inclined slide rail; the box door can be flipped up to about 90° and pushed inward, and has a guiding function. At the same time, the slide rail has an inclined angle, which helps the box door to be pushed into place, saving manpower. After reaching the maximum pushing distance, releasing the handle will allow the box door to fall on the top of the box; after this box door is opened, it is more convenient for stacking and disassembling pallets compared to conventional flip-down box doors.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The following is for reference. Figure 1-4 Describe this utility model;

[0033] The tray box with concealed door panels includes:

[0034] The housing 100 is fixedly installed at the bottom of the vehicle frame, and a receiving cavity is provided between the housing 100 and the vehicle frame; the side of the housing 100 is provided with an opening;

[0035] At least one pair of guide rails 200 are provided, which are detachably and symmetrically fixed on the side of the housing 100 and near the top of the housing 100; the guide rails 200 are provided with inclined slides 210.

[0036] The door 300 is located at the opening; after the door 300 is opened, it slides into the receiving cavity at the top of the box body 100 via the slide rail 210.

[0037] Specifically, a pair of symmetrically fixed V-shaped plates 310 are provided on the side of the box door 300 near the rear end;

[0038] The V-shaped plate 310 is provided with a hinged slide rod 320, which is confined within the slide rail 210.

[0039] Specifically, the slide bar 320 is provided with a pair of bearings that are fixedly sleeved at intervals;

[0040] A pair of bearings are respectively disposed on the side of the guide rail frame 200, and the upper and lower edges of the slide rail 210 are located between the pair of bearings.

[0041] Specifically, the front end (near the opening end) of the slide 210 is provided with a downwardly inclined barb groove 211.

[0042] With the door closed, the sliding rod is located within the front hook groove 211, effectively preventing vertical and horizontal swaying during vehicle movement, in conjunction with the cargo box latch below the door. When the door is opened and tilted, because the sliding rod is located within the hook groove 211, the door will not shift inward and collide with the door frame under the influence of gravity. When the door is tilted to approximately 90°, personnel can push it inward, overcoming a small amount of resistance before it enters the sliding track 210. During this stage, the component of the door's gravity in the direction of the sliding rod's movement assists in the operation. After the door is pushed to its limit, personnel can release their grip, and the inner reinforcing rib of the door can rest on the outer reinforcing rib of the top plate of the cargo box. Combined with the inclined track guiding the component of the door's gravity, this prevents the door from moving outward, allowing personnel to safely load and unload pallets.

[0043] Specifically, the bottom of the door 300 is provided with a handle that is fixedly connected.

[0044] Specifically, the bottom of the door 300 is detachably and fixedly connected to the body 100 via a vehicle compartment latch.

[0045] Specifically, the housing 100 has a storage area inside;

[0046] The bottom of the storage area is provided with a fixedly connected metal corrugated plate 110, which strengthens the bottom plate and effectively avoids severe deformation of the bottom plate due to excessive length and full load of the pallet under the requirement of lightweight.

[0047] Specifically, the box 100 has two openings, which are arranged opposite each other to meet the need for direct material feeding from both sides and improve the convenience of feeding and feeding small materials.

[0048] Specifically, the box 100 has a detachable and fixedly connected partition in the middle to divide the inner cavity of the box 100 and realize two independent storage areas.

[0049] Specifically, the door 300 is provided with folded edges around its perimeter, which effectively avoids severe deformation caused by excessive door length and only two turning points under the requirement of lightweight design.
