Description

Technical Field

[0001] The utility model belongs to the technical field of box-type semi-trailers, in particular to an adjustable roof of a box-type semi-trailer. Background Art

[0002] The van semi-trailer is improved on the basis of the van. One of its characteristics is that the cargo storage compartment is closed or semi-closed, which plays an excellent role in protecting against rain during cargo transportation.

[0003] The overall size of the box of the current box-type semi-trailer is certain, but the goods currently transported often include tall objects, and the goods are often too high, so that the goods can only be placed horizontally in the box, resulting in less remaining space inside, affecting the remaining loading space, resulting in overall limitations. Utility Model Content

[0004] The purpose of the utility model is to provide an adjustable roof of a box-type semi-trailer in order to solve the above-mentioned problem.

[0005] The technical solution adopted by the utility model is as follows: an adjustable roof of a box-type semi-trailer, comprising a frame, a box body is provided at the upper end of the frame, a roof is provided at the upper end cover of the box body, jacking members are installed at the four inner corners of the upper end of the box body, and the telescopic part of the jacking member is fixed to the bottom of the roof by a bolt member. When the telescopic part of the jacking member is extended, the roof moves upward to achieve the expansion of the space inside the box body.

[0006] In a preferred embodiment, the four ends of the ceiling extend downward to form waterproof baffles, and the height of the waterproof baffles is greater than the maximum lifting height of the lifting member.

[0007] In a preferred embodiment, a waterproof sealing strip that fits the inner wall of the waterproof baffle surface is half-embedded on the outer wall of the upper end of the compartment.

[0008] In a preferred embodiment, a plurality of guide grooves are circumferentially provided on the inner wall of the compartment, and a guide sliding block protruding from the inner wall of the ceiling is formed to guide and slide in the guide groove.

[0009] In a preferred embodiment, the upper end of the ceiling is provided with an arc-shaped guide surface with two sides inclined downward.

[0010] In a preferred embodiment, a silicone pad is half-embedded in the upper end surface of the guide groove.

[0011] In a preferred embodiment, a mounting frame is installed at the bottom of one of the guide grooves, an infrared receiver is installed in the mounting frame, and an infrared transmitter is installed at the bottom of the guide sliding block above the mounting frame.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0013] 1. In the utility model, an adjustable ceiling is designed on the compartment. When tall objects need to be transported, the height of the ceiling can be pre-adjusted according to the desired height. After the height adjustment is completed, the corresponding objects can be placed vertically in the compartment, thereby increasing the overall storage space and improving the overall applicability;

[0014] 2. In the present invention, waterproof blocking surfaces are designed at the four ends of the ceiling, which can ensure the overall sealing and waterproof effects after the overall height is raised. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] Reference Figure 1-3 , an adjustable roof of a box-type semi-trailer, including a frame 1, a box body 2 is provided at the upper end of the frame 1, a roof 3 is provided at the upper end cover of the box body 2, jacking members 4 are installed at the four corners of the upper inner part of the box body 2, and the telescopic part of the jacking member 4 is fixed to the bottom of the roof 3 by bolt members 6. When the telescopic part of the jacking member 4 is extended, the roof 3 moves upward to expand the space in the box body 2. An adjustable roof 3 is designed on the box body 2. When tall objects need to be transported, the height of the roof 3 can be pre-adjusted according to the desired height. After the height adjustment is completed, the corresponding objects can be placed upright in the box body 2, thereby increasing the overall storage space and improving the overall applicability.

[0021] The lifting member 4 may be an electric push rod, a hydraulic telescopic rod, or other electrically driven telescopic equipment, which will not be described in detail herein.

[0022] Furthermore, the four ends of the ceiling 3 extend downward to form waterproof baffles 302. When the height of the waterproof baffles 302 is greater than the maximum lifting height of the lifting member 4, waterproof baffles 302 are designed at the four ends of the ceiling 3. After the overall height is raised, the waterproof baffles 302 can also ensure the overall sealing and waterproof effects.

[0023] Furthermore, a waterproof sealing strip 5 which fits the inner wall of the waterproof baffle 302 is half-embedded in the upper outer wall of the body 2 . The designed sealing strip 5 can further improve the sealing effect of the contact position between the waterproof baffle 302 and the body 2 .

[0024] Furthermore, the inner wall of the compartment 2 is circumferentially provided with a plurality of guide grooves 201, and the inner wall of the ceiling 3 is protruded with a guide slider 303 which can slide and guide in the guide groove 201. Through the cooperation of the guide groove 201 and the guide slider 303, an auxiliary guiding effect can be played for the up and down movement of the ceiling 3, thereby ensuring the stability of the ceiling 3 when it is raised or lowered, and at the same time, it can also help increase the overall strength.

[0025] Furthermore, an arc-shaped guide surface 301 with two sides inclined downward is provided at the upper end of the ceiling 3 . The designed arc-shaped guide surface 301 can prevent water, snow, etc. from accumulating on the upper end surface of the ceiling 3 .

[0026] Furthermore, the upper end surface of the guide groove 201 is half-embedded with a silicone pad 7. When the lifting member 4 descends to drive the ceiling 3 to return to its original position, the bottom end surface of the ceiling 3 will first contact the silicone pad 7, thereby playing a buffering and protective role.

[0027] Furthermore, a mounting frame 10 is installed at the bottom of one of the guide grooves 201, an infrared receiver 8 is installed in the mounting frame 10, and an infrared transmitter 9 is installed at the bottom of the guide slider 303 above the mounting frame 10. Through the cooperation of the infrared receiver 8 and the infrared transmitter 9, the distance between the infrared receiver 8 and the infrared transmitter 9 can be measured, so that the overall rising height of the ceiling 3 can be known more accurately, thereby avoiding the possibility of rising too high and becoming shorter.

[0028] It should be emphasized that the infrared receiver 8, the infrared transmitter 9 and the lifting member 4 are all electrically connected to the control terminal and the power supply of the semi-trailer itself, so that the overall lifting operation can be directly controlled by the control terminal of the semi-trailer itself.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
