Technical Field

[0001] The utility model relates to the technical field of semi-trailers, and specifically, to a self-locking support device. Background Art

[0002] During the process of loading goods onto a semi-trailer, there are often some special cargo transportation requirements that cannot be effectively supported by the side plates of the semi-trailer itself. An additional support device is needed to solve the support requirements in special situations of the goods.

[0003] Generally speaking, these support devices are designed as frame structures with specific heights, or can achieve support requirements of various heights through assembly and other methods. However, this structural form is relatively simple and lacks consistency. It is often a temporary device assembled temporarily and does not have the ability to be reused.

[0025] The technical solution of the present utility model will be further described in detail below through specific embodiments.

[0026] As Figure 1 and Figure 2 shown, a support device with self-locking includes a base 1, an inner leg 2, an outer leg 3, a movable pin 4, a pin handle 5 and a locking hook 7.

[0027] The bottom end of the inner leg 2 is fixed on the base 1, and the base 1 includes a bottom plate 11 with a flat surface and a handle 12 provided at one end of the bottom plate.

[0028] The upper end of the inner leg 2 is slidably sleeved with the lower end of the outer leg 3. Specifically, in this embodiment, the inner leg 2 is a rectangular leg, the outer leg 3 is a leg with a rectangular cavity inside, the outer wall of the inner leg 2 and the inner wall of the outer leg 3 are arranged close to or in contact with each other, and a plurality of pin holes (not shown in the figure) are evenly distributed along the length direction of the inner leg 2.

[0029] The baffle 6 is a supported structure, which is integrally in the shape of an I-beam steel structure and is installed at the top of the outer leg 3 structure and is fixed by welding. A through hole 8 is provided in the middle of the outer leg 3 corresponding to the plurality of pin holes of the inner leg 2.

[0030] Specifically, in this embodiment, the outer leg 3 is provided with a vertical long hole 9 in the vertical direction, and a guide post 10 is correspondingly provided on the outside of the inner leg 2 for assisting in vertical movement guidance.

[0031] The movable pin 4 can be movably inserted and removed to cooperate with the through hole 8 and the pin holes. In this embodiment, the movable pin 4 is a cylindrical plug, and the movable pin 4 can penetrate through the outer leg 3 so as to lock the inner leg 2 and the outer leg 3 to control the height.

[0032] The outer end of the movable pin 4 is provided with a pin handle 5. In this embodiment, the pin handle 5 is designed in the shape of a rectangular frame, the pin handle 5 is fixed to the outer end of the movable pin 4, and the pin handle 5 is eccentrically arranged relative to the movable pin 4. Under the influence of its own weight, the pin handle 5 usually hangs down naturally.

[0033] The locking hook 7 is arranged on the outer leg 3 near the through hole for locking the pin handle 5. In this embodiment, the locking hook 7 is arranged as an inclined hook structure, the locking hook 7 is located below the through hole 8, and when the pin handle 5 rotates to the hanging state under the action of its own weight around the movable pin 4, the rectangular outer frame of the pin handle 5 is sleeved in the locking hook 7 and is locked, so that the movable pin 4 cannot move axially.

[0034] Working principle description:

[0035] Fix or place the base at the set position that needs to be supported, then adjust the matching height of the inner leg 2 and the outer leg 3 so that the height of the top or upper part of the outer leg matches the support height. After adjustment, insert the movable pin bearing into the corresponding pin hole and socket, lock the inner leg 2 and the outer leg 3, the height is locked, and then fix the outer leg 3 to the supported object, such as the baffle 6 in this embodiment is the supported object, and weld the two to achieve support.

[0036] Then, the pin handle 5 droops due to the influence of gravity and falls into the inclined locking hook, which blocks the axial shaking of the movable pin and prevents it from falling off.

[0037] Furthermore, the cooperation between the inner leg 2 and the outer leg 3, as well as the cooperation between the vertical long hole 9 and the guide column 10, are all for guiding and strengthening the structure, ensuring the smoothness of vertical movement and the stability of the structure.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
