Technical Field

[0001] This invention relates to an improvement in electrical equipment installation technology, belonging to the field of electrical automation, and particularly to an adjustable support device. Background Technology

[0002] Electrical automation is an emerging discipline in the field of electrical information, but due to its close relationship with people's daily lives and industrial production, it has developed very rapidly and is now relatively mature. It has become an important part of the high-tech industry and is widely used in industries such as industry, agriculture, and national defense. It plays an increasingly important role in the national economy, and its reach extends to all walks of life. From the design of a small switch to the research of aerospace aircraft, it is present everywhere. Electrical automation equipment is the specific equipment for realizing automated production and processing operations. In some production and processing processes, high requirements are required for the load-bearing and support structure of electrical automation production equipment, including structural strength, stability, buffer performance, and ease of movement.

[0003] The existing support devices have some shortcomings. Firstly, because the base is designed according to the equipment, during on-site construction, due to unforeseen circumstances and errors, the base is often too large, and although the reserved space is high enough, the reserved space on the ground is too small, which makes it impossible to install at the reserved position, or the ground at the installation position is uneven, causing the equipment to shake easily.

[0004] Chinese patent application CN201610878325.9, filed on October 8, 2016, discloses a support device comprising: a support body for supporting a cutting device within a pipe; a radial abutment structure disposed on the support body, the radial abutment structure extending and retracting in the radial direction of the support body to abut against the inner wall of the pipe, providing support for the cutting device within the pipe; and a radial transmission structure disposed on the support body and connected to the radial abutment structure, the radial transmission structure driving the radial abutment structure to extend and retract in the radial direction of the support body under the drive of the drive structure. However, this still does not solve the problem of not being able to adjust the installation position of the equipment according to the size of the reserved space.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this patent application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this adjustable support device, an arc-shaped groove is formed on the front of a hinge plate. One end of the arc-shaped plate passes through the arc-shaped groove and slides into it. An adjusting gear is provided on the inner wall of the arc-shaped groove. The inner ring of the arc-shaped plate meshes with the outer teeth of the adjusting gear to adjust the hinge plate. Rotating the adjusting gear engages with the arc-shaped plate, causing the hinge plate to shift, thereby shifting the four hinge plates towards the center. This reduces the footprint for installation, and the installation position can be adjusted according to the available space. To ensure overall stability, an adjusting gear, a locking block, a third bracket, and a locking screw are provided to lock the hinge plate in place. Therefore, this design is convenient to use and simple to operate.

[0018] 2. In this adjustable support device, a hinge connector and two assemblies are each hinged to a support member at their tops. Multiple sets of telescopic rods are provided on opposite sides of the two support members. Two telescopic rods on the same side are connected by two telescopic cylinders, and adjacent telescopic cylinders are connected by multiple sets of ribs. The device is placed on the area formed by the multiple telescopic rods and cylinders. The position of the corresponding fixing sleeve is adjusted, and the device is clamped using multiple clamping members. Then, the clamping members are locked with bolts to complete the fixation, providing better protection for the device. Starting two adjusting motors causes the first threaded rod to rotate, thereby moving the first threaded cylinder to complete the height adjustment. Therefore, this design allows for height adjustment and is easy to operate.

[0019] 3. In this adjustable support device, the inner wall of the fixing ring is provided with an annular dovetail groove. The inner wall of the dovetail groove slides in conjunction with the outer side of the dovetail ring. A hinge shaft is provided between the front and rear sides of the inner wall of the dovetail ring. A front second hinge piece, a first hinge piece, and a rear second hinge piece are sequentially fitted onto the outer side of the hinge shaft. The rear ends of the front second hinge pieces are connected to the front ends of the first hinge piece, and the rear ends of the first hinge piece are connected to the front ends of the rear second hinge pieces. The fixing ring allows the device to rotate easily, enabling operation in different directions even in narrow spaces. The five supports further enhance the overall stability of the device, preventing wobbling due to the tilt of the hinge plate. The upper and lower fixing plates also provide excellent shock absorption. Therefore, this design offers high stability and safe placement of the device. Attached Figure Description

This completes the height adjustment of the device. After the adjustment is completed, the device can be used normally.

[0039] When the reserved position does not meet the installation requirements of the equipment, observe the size of the reserved position and then adjust one of the hinge plates 33. Rotating the adjusting gear 35 and cooperating with the arc plate 31 can cause the hinge plate 33 to shift, thereby causing the four hinge plates 33 to shift towards the center, thus reducing the footprint for installation. At the same time, as the four hinge plates 33 move towards the center, in order to ensure the overall stability, an adjusting gear 35, a locking block 36, a third bracket 37, and a locking screw 38 are provided to lock one of the hinge plates 33.

[0040] The device features a fixed ring 1, allowing for easy rotation and operation in narrow spaces from different directions. It also includes a hinge plate 33, enabling installation in smaller spaces when the required mounting location is unavailable, ensuring normal operation. Five supports 42 further stabilize the device, preventing wobbling due to the tilt of the hinge plate 33. The upper and lower fixed plates 43 and 44 provide excellent shock absorption.
