AI Technical Summary
The plastic base of the existing adjustment base is prone to wear after bearing weight, resulting in a short lifespan and causing the adjustment function to fail.
The adjustable foot uses an internal threaded sleeve that engages with the external thread of the adjusting rod, and is mounted inside the base sleeve with a ball bearing to reduce friction and improve stability. Height adjustment is achieved by rotating the adjusting rod.
It improves the load-bearing capacity, adjustment accuracy and service life of the adjustment base, reduces friction loss and energy consumption, and extends the service life of the plastic base sleeve.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of adjustable base technology, specifically an adjustable base. Background Technology
[0002] In the current market environment, the design of adjustable feet for various equipment, furniture, and devices generally adopts a structural mode in which the load-bearing shaft directly contacts and is fixed to the plastic base. This design does provide the necessary stability and adjustment function in the initial stages of use, meeting basic load-bearing and height adjustment needs.
[0003] However, as the usage time increases and the load is repeatedly applied, the limitations of this structure gradually become apparent. When adjusting the height after bearing weight, the plastic base is prone to wear and has a short lifespan. Therefore, there is an urgent need for an adjustable base. Utility Model Content
[0004] The purpose of this invention is to provide an adjustable base to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an adjustment base, including an adjustment foot, a threaded sleeve, a bottom sleeve, an adjustment rod, and a ball bearing, wherein the threaded sleeve is installed inside the adjustment foot, the ball bearing is installed inside the bottom sleeve, and the adjustment rod is installed on the ball bearing.
[0006] Preferably, the outer surface of the adjusting rod is provided with an external thread, and the external thread on the surface of the adjusting rod is adapted to the threaded sleeve.
[0007] Preferably, the outer surface of the adjusting foot is provided with vertical grooves.
[0008] Preferably, the base sleeve is made of plastic.
[0009] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0010] Firstly, the adjusting foot of this utility model serves as the supporting part of the entire adjusting base. The adjusting foot has an internal space for installing a threaded sleeve, providing guidance and support for the up-and-down movement of the adjusting rod. The threaded sleeve is installed inside the adjusting foot and matches the external thread of the adjusting rod. Precise height adjustment is achieved by rotating the adjusting rod. The threaded sleeve design enhances the stability of the adjusting rod under load. The base sleeve is made of plastic and contains a ball bearing, effectively reducing direct friction between the adjusting rod and the base sleeve, extending the service life of the plastic base sleeve. The addition of the ball bearing also improves the smoothness and accuracy of the adjustment. The outer surface of the adjusting rod has an external thread that fits tightly with the threaded sleeve. Height adjustment is achieved through rotation. The adjusting rod is mounted on the ball bearing, reducing frictional loss during adjustment. The ball bearing is installed inside the base sleeve, acting as an intermediary between the adjusting rod and the base sleeve. The rolling friction of the ball bearing is far lower than the sliding friction, significantly reducing energy consumption and wear during adjustment. This effectively solves the problem of easy wear and short lifespan of the plastic base of existing adjusting feet when adjusting height under load, thus improving the load-bearing capacity, adjustment accuracy, and service life of the adjusting base.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] This utility model provides the following technical solution:
[0017] Please see Figure 1 , Figure 2 and Figure 3An adjusting base includes an adjusting foot 1, a threaded sleeve 2, a base sleeve 3, an adjusting rod 4, and a ball bearing 5. The threaded sleeve 2 is installed inside the adjusting foot 1, the ball bearing 5 is installed inside the base sleeve 3, and the adjusting rod 4 is installed on the ball bearing 5.
[0018] The outer surface of the adjusting rod 4 is provided with external threads, and the external threads on the surface of the adjusting rod 4 are adapted to the threaded sleeve 2.
[0019] The outer surface of the adjusting foot 1 is provided with vertical grooves.
[0020] The bottom sleeve 3 is made of plastic.
[0021] Through the above technical solution, the adjusting foot 1 serves as the supporting part of the entire adjusting base. The adjusting foot 1 has an internal space for installing a threaded sleeve 2, providing guidance and support for the up-and-down movement of the adjusting rod 4. The threaded sleeve 2 is installed inside the adjusting foot 1 and is compatible with the external thread of the adjusting rod 4. Precise height adjustment is achieved by rotating the adjusting rod 4. The design of the threaded sleeve 2 enhances the stability of the adjusting rod 4 under load. The bottom sleeve 3 is made of plastic and contains a ball bearing 5, effectively reducing direct friction between the adjusting rod 4 and the bottom sleeve 3, extending the service life of the plastic bottom sleeve 3. The addition of the ball bearing 5 also improves... The smoothness and precision of the adjustment are improved. The outer surface of the adjusting rod 4 is designed with external threads, which fit tightly with the threaded sleeve 2. The height is adjusted by rotation. The adjusting rod 4 is mounted on the ball bearing 5, which reduces friction loss during the adjustment process. The ball bearing 5 is installed inside the base sleeve 3, serving as an intermediary between the adjusting rod 4 and the base sleeve 3. The rolling friction of the ball bearing 5 is much lower than that of the sliding friction, which significantly reduces energy consumption and wear during the adjustment process. This effectively solves the problem that the plastic base of the existing adjusting foot 1 is prone to wear and has a short lifespan when adjusting the height after bearing weight. It improves the load-bearing capacity, adjustment precision and service life of the adjusting base.
