Description

A ground adjustment support device

technical field

The utility model belongs to the technical field of aircraft ground maintenance tools, in particular to a ground adjustment support device.

Background technique

Some mobile workbenches with mobile casters, ladder racks, transport racks, etc. are often used in aircraft ground maintenance work. All kinds of workbenches, ladder frames or transport frames installed with movable casters may have a slope on the ground or an unbalanced center of gravity when docking or working. Without protective measures, it is easy to slip and bring safety hazards. The mobile casters are mostly eccentric structures, and the frame shaking caused by the eccentricity of the casters cannot be controlled by the brakes that come with the casters. Therefore, some supporting devices are usually used to support and fix workbenches with movable casters, ladder frames, transport frames, etc., to prevent them from slipping and shaking.

However, some of the support feet used on the market today are not convenient to use, and have the following problems:

1. The rivet structure is usually used, which cannot carry large weights.

2. When adjusting the height, you need to use a wrench to achieve it.

3. The fixed vertical structure is not stable enough when there are some slopes on the ground.

Utility model content

In order to solve the above problems, the present invention provides a ground adjusting support device, which is simple in structure, convenient in use and good in stability.

A ground adjustment support device includes a base. A pressure plate is arranged above the base, and the base and the pressure plate are detachably connected by locking screws; a screw rod is arranged above the pressure plate, and a spherical connection block is arranged at the bottom of the screw rod, and the spherical connection block is embedded the pressing plate is rotatably connected with it; the screw rod is provided with a thread on the outer surface; a frame body connecting block is arranged above the pressing plate, and the screw rod vertically passes through the frame body connecting block and is screwed with it; The frame body connecting block is provided with a plurality of horizontal mounting holes, and connecting screws are provided in the horizontal mounting holes.

Further, the top of the screw rod is provided with an L-shaped handle.

Further, the number of the horizontal mounting holes is four.

Compared with the prior art, the beneficial effects of the present utility model:

1. Use the connecting screws on the frame body connecting block to connect the frame body with movable casters, which can fix the frame body and prevent the frame body from slipping and shaking.

2. The hand-operated screw rod is used to lift and lower, and the height can be adjusted without using a wrench, which is easy to operate.

3. The structure of pressing the pressure plate on the base through the locking screw makes up for the shortcoming that the rivet structure on the market is easy to fall off, and can carry more weight.

4. The bottom of the screw rod is connected by a spherical connecting block embedded in the pressure plate, so that the device can adapt to the ground with some slopes, and can ensure that the screw rod and the connected frame are in a vertical position, which is convenient for operation.

Description of drawings

FIG. 1 is a schematic structural diagram of a ground adjustment support device according to the present invention.

FIG. 2 is a cross-sectional view of a ground adjustment support device according to the utility model.

Description of reference numbers:

In the figure, the base 1, the pressure plate 2, the locking screw 3, the lead screw 4, the L-shaped handle 5, the frame connecting block 6, the horizontal installation hole 7, and the spherical connecting block 8 are included.

Detailed ways

In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

Please refer to the accompanying drawings 1 and 2 of the description, the utility model is a ground adjustment support device, including a base 1 . A pressure plate 2 is arranged above the base 1, and the base 1 and the pressure plate 2 are detachably connected by locking screws 3; a screw rod 4 is arranged above the pressure plate 2, and the bottom of the screw rod 4 is provided with a spherical connection Block 8, the spherical connecting block 8 is embedded in the pressing plate 2 and connected to it in rotation; the outer surface of the screw rod 4 is provided with threads; 4. Vertically pass through the frame body connecting block 6 and screw it with it; the frame body connecting block 6 is provided with a number of horizontal mounting holes 7. As a preference but not limitation, the number of the horizontal mounting holes 7 is four ; The horizontal mounting hole 7 is provided with connecting screws for connecting the frame with moving casters.

As a preference but not a limitation, the top of the screw rod 4 is provided with an L-shaped handle 5, which is convenient for rotating the screw rod 4, and the frame body connecting block 6 is adjusted by the thread on the outer surface of the screw rod 4 to adjust the upper and lower heights.

The use method of this utility model is:

Several ground adjustment support devices provided by the present invention are used, which are symmetrically arranged at both ends of the frame body with movable casters (just keep the symmetry), and the frame body is fixed on the frame body connecting block 6 by connecting screws. Using the L-shaped handle 5 to rotate the screw rod 4 horizontally, through the thread structure on the surface of the screw rod 4, the frame body connecting block 6 can be driven to adjust the upper and lower heights. When encountering some sloped ground, the base 1 is close to the ground, and under the action of gravity, the lead screw 4 and the frame can be kept in a vertical position. Through the cooperative use of several of the supporting devices, the frame body with movable casters can be fixed to prevent it from slipping.

The above specific embodiments are only preferred embodiments of this creation, and are not intended to limit this creation. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this creation shall be included in this creation. within the scope of protection.
