Abstract
Description
Technical Field
[0001] This utility model relates to the field of support technology, and in particular to an adjustable support. Background Technology
[0002] Supports are widely used in building construction, equipment installation, and object support as devices for load-bearing and positioning. In practical applications, due to differences in the height of the supported object and on-site working conditions, there are high requirements for the height adaptability of the supports.
[0003] In existing technologies, some supports adopt a fixed structure design, and their height cannot be adjusted. They are only suitable for support scenarios with specific heights, resulting in poor flexibility and difficulty in meeting diverse usage needs. Other adjustable supports, although capable of height adjustment, have obvious drawbacks: for example, some supports lack a dedicated locking mechanism, and after height adjustment, they rely solely on the friction of the threads themselves to maintain their position. When affected by vibration, load changes, etc., they are prone to loosening, causing the support height to shift and posing a safety hazard. In addition, some adjustment structures are complex in design, requiring multiple steps to complete height adjustment and fixation, resulting in poor ease of use.
[0004] Therefore, an adjustable support needs to be designed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable support. This invention features a simple structure, convenient adjustment, and reliable locking. By optimizing the adjustment and locking mechanism, it solves problems such as non-adjustable height, cumbersome adjustment operations, or insecure locking in existing supports, thereby improving the adaptability and safety of the support.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An adjustable support includes a base assembly, a locking nut, a lead screw, and an adjusting nut. The main base assembly is formed by assembling and fixing a base cylinder and a base plate. The outer wall of the base cylinder is provided with threads that match the locking nut. The adjusting nut is threadedly engaged with the lead screw, and the height of the lead screw mounted on the main base assembly can be changed by rotating the adjusting nut. The locking nut is engaged with the threads at the upper end of the base cylinder to fix the adjusting nut.
[0008] Preferably, the base cylinder and the base plate are assembled and fixed by welding.
[0009] Preferably, the adjusting nut changes the height of the lead screw by rotating it counterclockwise or clockwise.
[0010] Preferably, a hand-held block is fixedly connected to the upper end of the lead screw, and the outer wall of the hand-held block is provided with a damping layer.
[0011] Preferably, the inner wall of the base cylinder is symmetrically provided with two guide grooves, the upper ends of the two guide grooves are connected to the outside, and the outer wall of the lead screw is symmetrically fixedly connected with two guide blocks.
[0012] Preferably, the outer walls of the two guide blocks are fitted with the inner walls of the corresponding guide grooves, and the contact surfaces of the guide blocks and guide grooves are both smoothed to form a low-friction mating surface.
[0013] Compared with existing technologies, the advantages of this device are:
[0014] 1. Compared with the existing technology, this device can drive the lead screw to adjust the height by rotating the adjusting nut, without the need to directly rotate the lead screw. The adjustment method is simpler and less labor-intensive, and can accurately control the height change. At the same time, after the height adjustment is completed, the lead screw, adjusting nut and base assembly are tightly locked by the locking nut. Compared with the structure that only relies on the self-locking of the thread, the locking reliability is significantly improved, which can effectively avoid loosening under the influence of vibration or load and ensure the stability of the support.
[0015] 2. Compared with existing technologies, the upper end of the lead screw is equipped with a hand block with a damping layer, which makes it easier for the operator to hold the screw stably during adjustment, reduces hand slippage, and improves operating comfort.
[0016] 3. Compared with existing technologies, the guide block and guide groove eliminate the need to manually limit the height of the lead screw when adjusting it, making it easier for operators to work in confined spaces. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Example 1
[0023] Reference Figures 1-2 An adjustable support includes a base assembly, a locking nut 2, a lead screw 3, and an adjusting nut 5. The main base assembly is formed by assembling and fixing a base cylinder 4 and a base plate 1. The base cylinder 4 and the base plate 1 are assembled and fixed by welding. This welding method makes the base assembly form a stable integral structure. Compared with other connection methods, such as bolt connection, it has higher strength and stability, and can effectively avoid problems such as loosening and deformation during long-term use or under large loads. The outer wall of the base cylinder 4 is provided with threads 6 that match the locking nut 2. The adjusting nut 5 is threadedly engaged with the lead screw 3. By rotating the adjusting nut 5, the height of the lead screw 3 installed on the main base assembly can be changed. The locking nut 2 is engaged with the threads 6 at the upper end of the base cylinder 4 to fix the adjusting nut 5. The adjusting nut 5 changes the height of the lead screw 3 by rotating it left or right. A hand block is fixedly connected to the upper end of the lead screw 3. The outer wall of the hand block is provided with a damping layer. The design of the damping layer can increase the friction between the hand and the hand block and prevent slippage during operation.
[0024] The functional principle of this utility model can be explained through the following operation: When using the support, first place the screw 3 with the adjusting nut 5 threaded on it inside the base cylinder 4, so that the adjusting nut 5 contacts the upper end of the base cylinder 4. Then, adjust the height of the screw 3 as needed by rotating the adjusting nut 5 clockwise or counterclockwise. At the same time, the operator holds the screw 3 firmly with his other hand. During the rotation of the adjusting nut 5, the screw 3 will only move up and down, so that the entire support is adjusted to a suitable height. Then, the support can be placed in the designated position for support. This adjustment method is simple and direct, and the operator can quickly master it. Moreover, by controlling the number of rotations of the adjusting nut 5, the lifting height of the screw 3 can be controlled relatively accurately.
[0025] Example 2
[0026] Reference Figure 3 The difference between this embodiment and Embodiment 1 is that the inner wall of the base cylinder 4 is symmetrically provided with two guide grooves 7, the upper ends of which are connected to the outside. Two guide blocks 8 are symmetrically fixed to the outer wall of the lead screw 3. The outer walls of the two guide blocks 8 fit against the inner walls of the corresponding guide grooves 7. The contact surfaces of the guide blocks 8 and the guide grooves 7 are smoothed, forming a low-friction mating surface. This special guide structure design further optimizes the adjustment performance of the support. When the lead screw 3 is placed into the base cylinder 4, the two guide blocks 8 need to be aligned with the guide grooves 7 so that they are located within the guide grooves 7. Therefore, during the subsequent rotation of the adjusting nut 5, the cooperation between the guide grooves 7 and the guide blocks 8 restricts the rotation of the lead screw 3, eliminating the need for manual intervention to limit its movement.
[0027] In this embodiment, when the lead screw 3 is placed into the base cylinder 4, the two guide blocks 8 need to be aligned with the guide groove 7 so that the two guide blocks 8 are located in the guide groove 7. This restricts the rotation of the lead screw 3 during the subsequent rotation of the adjusting nut 5, thus eliminating the need for staff to manually limit the position of the lead screw 3, making it easier to operate in a confined space.
[0028] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
