Abstract
Description
Technical Field
[0001] This utility model relates to the field of body support technology, and in particular to a body support structure with adaptive adjustment function. Background Technology
[0002] With the continuous and vigorous development of the modern logistics industry and the increasing demand for transportation, trucks, as the core carriers in the logistics transportation system, have shown a steady upward trend in their number of vehicles. In the complex system of the overall body structure design of trucks, the support structure occupies a pivotal position. It is not only a key component connecting the frame and the cargo box, but also bears the important mission of directly supporting the weight of the cargo box and the goods it carries.
[0003] Most common box support structures currently rely on hydraulic cylinders to achieve height adjustment. In practical applications, relying solely on hydraulic cylinders for adjustment lacks an effective matching limit locking mechanism. Once the oil supply line ruptures, the hydraulic cylinder will quickly fall back, thus seriously threatening the safety of the box support. Utility Model Content
[0004] This utility model relates to a box support structure with adaptive adjustment function, which solves the problem that most existing box support structures rely on hydraulic cylinders to achieve height adjustment. In actual application, relying solely on hydraulic cylinders for adjustment lacks an effective matching limit locking mechanism. Once the oil supply line ruptures, the hydraulic cylinder will quickly fall back, thereby seriously threatening the safety of the box support.
[0005] In a first aspect, this utility model provides a body support structure with adaptive adjustment function, specifically including: a hollow tube base, a hydraulic cylinder, a movable support column, a limiting sleeve, and a positioning sleeve; the hydraulic cylinder is installed inside the hollow tube base, the movable support column is connected to the top of the hollow tube base, and the hydraulic cylinder is located at the bottom of the movable support column; the limiting sleeve is fitted outside the hollow tube base, and the limiting sleeve is connected to the movable support column; the positioning sleeve is fitted outside the hollow tube base, and the positioning sleeve is located at the bottom of the limiting sleeve.
[0006] Furthermore, the lower end of the movable support column is slidably connected to the hollow tube seat, and the top end of the piston rod of the hydraulic cylinder contacts the bottom end of the movable support column.
[0007] Furthermore, the hollow tube base is symmetrically provided with guide holes on its outer side, and the bottom end of the movable support column is symmetrically provided with sliders. The sliders are slidably connected in the guide holes, and the sliders and guide holes are slidably engaged to guide the movable support column. The movable support column is moved up and down by a hydraulic cylinder.
[0008] Furthermore, the limiting sleeve is rotatably connected to the hollow tube base. Two comb-shaped holes are arranged around the outside of the limiting sleeve. The comb-shaped holes are connected to the guide holes. The end of the slider is slidably connected in the comb-shaped holes. During the up and down movement of the movable support column, the slider moves in the vertical channel of the comb-shaped holes. After the hydraulic cylinder drives the movable support column to move to the required height, the slider is in the position where the vertical channel and the horizontal channel of the comb-shaped holes are connected. Rotating the limiting sleeve moves the slider to the end of the horizontal channel of the comb-shaped holes, and the movable support column is fixedly supported by the limiting sleeve.
[0009] Furthermore, the positioning sleeve is slidably connected to the hollow tube base, and guide blocks are symmetrically arranged on the outside of the hollow tube base. Sliding holes are symmetrically arranged on the outside of the positioning sleeve. The guide blocks are slidably connected in the sliding holes, and the guide blocks and sliding holes are slidably engaged to guide the movement of the positioning sleeve.
[0010] Furthermore, a spring is fitted outside the hollow tube seat, with the lower end of the spring contacting the hollow tube seat and the upper end of the spring contacting the bottom of the positioning sleeve. The spring provides an elastic reset effect for the positioning sleeve.
[0011] Furthermore, the top of the positioning sleeve is symmetrically provided with positioning blocks, and the bottom of the limiting sleeve is symmetrically provided with positioning grooves. The positioning blocks are slidably inserted into the positioning grooves. After the slider moves to the end of the transverse channel of the comb-shaped hole, the positioning groove is located directly above the positioning block. The positioning sleeve moves upward under the influence of the spring force, so that the positioning block is inserted into the positioning groove. The positioning sleeve achieves the locking and positioning effect of the limiting sleeve.
[0012] This utility model provides a body support structure with adaptive adjustment function, which has the following beneficial effects: In use, the slider slides in conjunction with the guide hole to guide the movement of the movable support column. The hydraulic cylinder drives the movable support column to move up and down, achieving an adaptive adjustment effect for the support height of the box body. During the up and down movement of the movable support column, the slider moves within the vertical channel of the comb-shaped hole. After the hydraulic cylinder drives the movable support column to the required height, the slider is positioned where the vertical channel and the horizontal channel of the comb-shaped hole communicate. Rotating the limiting sleeve moves the slider to the end of the horizontal channel of the comb-shaped hole, and the limiting sleeve provides fixed support for the movable support column, preventing it from falling and ensuring the stability of the movable support column support.
[0013] In addition, the guide block slides with the sliding hole to guide the movement of the positioning sleeve. The spring provides an elastic reset effect for the positioning sleeve. After the slider moves to the end of the horizontal channel of the comb-shaped hole, the positioning groove is located directly above the positioning block. The positioning sleeve moves upward under the influence of the spring force, causing the positioning block to be inserted into the positioning groove. The positioning sleeve locks and positions the limiting sleeve, effectively ensuring the safety of the support.

[0021] In this embodiment of the utility model, the limiting sleeve 4 is rotatably connected to the hollow tube seat 1, and two comb-shaped holes 41 are arranged around the outside of the limiting sleeve 4. The comb-shaped holes 41 are connected to the guide hole 11, and the end of the slider 31 is slidably connected to the comb-shaped holes 41. Using the above technical solution, during the up-and-down movement of the movable support column 3, the slider 31 moves within the vertical channel of the comb-shaped hole 41. After the hydraulic cylinder 2 drives the movable support column 3 to the required height, the slider 31 is positioned where the vertical channel and the horizontal channel of the comb-shaped hole 41 are connected. By rotating the limiting sleeve 4, the slider 31 moves to the end of the horizontal channel of the comb-shaped hole 41. The limiting sleeve 4 provides fixed support for the movable support column 3, preventing it from falling and ensuring the stability of the movable support column 3.
[0022] In Example 2, based on Example 1, the positioning sleeve 5 is slidably connected to the hollow tube seat 1. The hollow tube seat 1 is symmetrically provided with guide blocks 12 on the outside, and the positioning sleeve 5 is symmetrically provided with sliding holes 51 on the outside. The guide blocks 12 are slidably connected in the sliding holes 51. The hollow tube seat 1 is fitted with a spring 6 on the outside.
