Description

Technical Field

[0001] This utility model belongs to the field of lifting support technology, specifically relating to a rapid lifting support device. Background Technology

[0002] In some cases, it is necessary to rapidly raise and lower a support at multiple defined heights, while ensuring structural safety and reliability. If the lifting height is large and the number of lifting positions is numerous, the lifting mechanism often occupies a significant amount of space and is difficult to operate.

[0003] Therefore, a rapid lifting and lowering support device is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a rapid lifting and lowering support device.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] The present invention provides a rapid lifting support device, comprising a support outer cylinder, a support inner cylinder slidably connected to the inner cavity of the support outer cylinder, and a lifting locking mechanism disposed at the upper end of the support outer cylinder.

[0007] The upper outer wall of the supporting outer cylinder is machined with external threads;

[0008] The lifting and locking mechanism includes a clamping seat and a set of clamping blocks;

[0009] The clamping seat has a cylindrical structure. The lower end of the inner wall of the clamping seat is machined with an internal thread that matches the upper outer wall of the supporting outer cylinder. A set of circumferentially distributed vertical positioning grooves are provided in the middle of the inner wall of the clamping seat. The upper end of the inner wall of the clamping seat is machined with an upwardly converging frustum clamping surface.

[0010] The clamping block is a block-shaped component whose width matches the width of the vertical positioning groove of the clamping seat. The inner side of the clamping block is an arc surface that matches the outer diameter of the inner cylinder of the support. The upper outer side of the clamping block is machined with a frustum positioning surface that matches the frustum clamping surface of the clamping seat.

[0011] The lower end of the inner wall of the clamping seat is threaded to the upper outer wall of the outer support cylinder. Each clamping block is installed in each vertical positioning groove of the clamping seat. When the clamping seat is rotated, the clamping seat moves up and down relative to the outer support cylinder. The frustum clamping surface of the clamping seat drives each clamping block to clamp or release the inner support cylinder.

[0012] The outer wall of the clamping seat is provided with a rotating handle to facilitate the rotation of the clamping seat.

[0013] The outer wall of the inner support cylinder is provided with a set of axially distributed annular positioning platforms, so that the upper ends of each clamping block provide axial support to the inner support cylinder through the annular positioning platforms.

[0014] Work process

[0015] When controlling the lifting and lowering of the inner support cylinder, the clamping seat is rotated to move upward relative to the outer support cylinder. The frustum clamping surface of the clamping seat moves away from the clamping blocks, releasing the lock on the inner support cylinder. After moving the inner support cylinder to the predetermined support height, the clamping seat is rotated again to move downward relative to the outer support cylinder. The frustum clamping surface of the clamping seat drives the clamping blocks to clamp the inner support cylinder inward, thus positioning the support height of the inner support cylinder.

[0016] Beneficial effects:

[0017] 1. Multi-level lifting can be designed and manufactured according to the determined height, position, quantity and storage space, which is convenient and flexible.

[0018] 2. The lifting process can be operated manually, which is quick and convenient.

[0019] 3. The clamping blocks clamp the lifting pipe steps, ensuring a stable and secure structure.

[0020] 4. The operation process is simple, just loosen and tighten, reducing labor intensity. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] Example

[0024] like Figure 1 As shown, a rapid lifting support device of this utility model includes a support outer cylinder 1, a support inner cylinder 2 slidably connected to the inner cavity of the support outer cylinder 1, and a lifting locking mechanism disposed at the upper end of the support outer cylinder 1.

[0025] The outer wall of the inner support cylinder 2 is provided with a set of axially distributed annular positioning platforms, and the upper outer wall of the outer support cylinder 1 is machined with external threads.

[0026] The lifting and locking mechanism includes a clamping seat 3 and a set of clamping blocks 4;

[0027] The clamping seat 3 has a cylindrical structure. The lower end of the inner wall of the clamping seat 3 is machined with an internal thread that matches the upper outer wall of the supporting outer cylinder 1. A set of circumferentially distributed vertical positioning grooves are provided in the middle of the inner wall of the clamping seat 3. The upper end of the inner wall of the clamping seat 3 is machined with an upwardly converging frustum clamping surface.

[0028] The clamping block 4 is a block-shaped part whose width matches the width of the vertical positioning groove of the clamping seat 3. The inner side of the clamping block 4 is an arc surface that matches the outer diameter of the inner support cylinder 2. The upper outer side of the clamping block 4 is machined with a frustum positioning surface that matches the frustum clamping surface of the clamping seat 3.

[0029] The lower end of the inner wall of the clamping seat 3 is threaded to the upper outer wall of the outer support cylinder 1. Each clamping block 4 is installed in each vertical positioning groove of the clamping seat 3. When the clamping seat 3 is rotated, the clamping seat 3 moves up and down relative to the outer support cylinder 1. The frustum clamping surface of the clamping seat 3 drives each clamping block 4 to clamp or release the inner support cylinder 2.

[0030] The outer wall of the clamping seat 3 is provided with a rotating handle to facilitate the rotation of the clamping seat 3.

[0031] Work process

[0032] When controlling the lifting and lowering of the inner support cylinder 2, the clamping seat 3 is rotated, causing the clamping seat 3 to move upward relative to the outer support cylinder 1. The frustum clamping surface of the clamping seat 3 moves away from each clamping block 4, releasing the lock on the inner support cylinder 2. After moving the inner support cylinder 2 to the predetermined support height, the clamping seat 3 is rotated again, causing the clamping seat 3 to move downward relative to the outer support cylinder 1. The frustum clamping surface of the clamping seat 3 drives each clamping block 4 to clamp the inner support cylinder 2 inward, thus positioning the support height of the inner support cylinder 2.
