Detailed Description

Referring to fig. 2-4, the utility model provides a quick detach formula stand, including quick detach stand body 1, slide spacing have with slot 3 matched with grafting post 4 on semitrailer automobile body 2 in the holding cavity of quick detach stand body 1 bottom. A vertical guide groove 1-1 is arranged on the quick-release upright post body 1, and a guide pin 5 which is matched with the vertical guide groove 1-1 to form a guide structure is arranged on the inserting post 4.

Quick detach stand body 1 is the square of chamfer or two corner chamfers around for the structure truncation face of cavity formula, and it can hold spliced pole 4 and can lead spliced pole 4. The vertical guide groove 1-1 is used for guiding in cooperation with the guide pin 5 and simultaneously limiting the extending and retracting length of the plug column 4 relative to the quick-release column body 1. If the inserting groove 3 and the inserting column 4 are difficult to disassemble after inserting, the inserting structure can be released by knocking the guide pin 5 upwards.

The length of the inserting column 4 is 2-3 times of the depth of the slot 3. So as to ensure the connection strength between the quick-release upright post body 1 and the slot 3. The slot 3 is formed by bending a steel plate and is connected with the semi-trailer body 2.

The top of the vertical guide groove 1-1 is provided with a horizontal limiting groove 1-2 which is matched with the guide pin 5 to form a plug-in post limiting structure, and the plug-in post 4 is provided with a horizontal guide through groove 4-1 which is matched with the guide pin 5 and penetrates through the plug-in post 4.

The splicing column 4 is of a hollow structure as a whole, and the section is square with four chamfered edges. After the quick-release type upright post is disassembled, the inserting post 4 is required to be integrally contracted into the quick-release upright post body 1, at the moment, the guide pin 5 is positioned at the top of the vertical guide groove 1-1, and the horizontal limiting groove 1-2 is flush with the horizontal guide through groove 4-1, and the guide pin 5 can be matched with the horizontal limiting groove 1-2 to realize that the inserting post 4 is integrally limited in the quick-release upright post body 1 by moving along the horizontal guide through groove 4-1. When the plugging column 4 is required to be capable of extending out, only the guide pin 5 needs to be shifted into the vertical guide groove 1-1 from the horizontal limiting groove 1-2.

The inserting column 4 is provided with a strip-shaped connecting groove 4-2, a connecting plate 6 is limited in the connecting groove 4-2, and the inner end part of the guide pin 5 is connected with the connecting plate 6. The connecting plate 6 is circular, the diameter of the connecting plate is smaller than the width of the connecting groove 4-2 and larger than the width of the horizontal guide through groove 4-1, and the thickness of the connecting plate is smaller than the depth of the connecting groove 4-2. The bottom of the splicing column 4 is provided with a material leaking strip hole 4-3. As the materials can enter the gap between the inserting column 4 and the slot 3 in the transportation process, the inserting column 4 can be difficult to pull out from the slot 3, and the material leakage strip hole 4-3 is designed to enable the materials in the gap to enter the cavity of the inserting column 4 through the strip hole, thereby being beneficial to pulling out the inserting column 4.

Since there may be no suitable tool for striking the guide pin 5 at the site of disassembly, a jack post drive assembly is provided at the free end of the guide pin 5, which jack post drive assembly comprises a handle 7 hinged to the guide pin 5 and a cam plate 8 provided at the bottom of the handle 7. And a stress plate 9 matched with the cam plate 8 is arranged on the outer side of the slot 3. Because the material is in the plug post 4 and the slot 3 the gap is more leads to the plug post 4 to extract the difficulty, through the lever structure of handle 7 and cam plate 8 constitution, hold the top of handle 7 and rotate handle 7 simultaneously, through the cooperation between the cam surface on the cam plate 8 and atress board 9 slowly with the uide pin 5 upwards lift and then lift up plug post 4, can conveniently shift out plug post 4 from slot 3 this moment. In this embodiment the handle 7 is of integral construction with the cam plate 8.

Referring to the attached drawing 1, the semitrailer comprises a semitrailer body 2, a plurality of upright posts 10 arranged on the semitrailer body 2 and the quick release type upright posts. The quick-release type upright post is arranged between the two upright posts 10, and the carriage plate 11 and the bin fence 12 are arranged between the quick-release type upright post and the upright posts 10, so that the quick-release type upright post and the corresponding carriage plate 11 and bin fence 12 can be conveniently detached, and a bucket of a large forklift can conveniently enter a semi-trailer for unloading operation. The column 10 may be fixed or may be of the same construction as a quick release column.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
