Description

Technical Field

[0001] This utility model relates to telescopic columns, and more particularly to a telescopic column protective frame. Background Technology

[0002] Telescopic columns are widely used in industrial equipment, furniture, construction, and other fields, primarily for supporting and securing equipment or components. Most telescopic columns have a protective frame, whose main purpose is to provide protection and support for the column, preventing damage from external impacts and friction during use. It also helps maintain the column's stability and straightness, preventing debris from entering the gap between the inner and outer columns, thus improving the column's lifespan and reliability. In existing technology, the protective frame of telescopic columns is typically fixed with bolts or directly clipped to the end of the column. Bolt fixing is complex to install, inconvenient to disassemble, and requires specialized tools; while direct clipping, although simple to install, is prone to loosening and falling off, affecting the column's stability and lifespan. Utility Model Content

[0003] Purpose of the utility model: The purpose of this utility model is to provide a telescopic column guard frame that is easy to assemble and disassemble and has high structural stability.

[0004] Technical solution: The telescopic column guard frame of this utility model includes a frame body that is snapped onto the outer column port of the telescopic column; it also includes a barb connected to the frame body, the barb being installed on friction plates on the outer surface of the inner column and the inner surface of the outer column.

[0005] Preferably, the frame includes a protective frame skeleton and a flexible wrapping layer. The barb is integrally formed with the end of the protective frame skeleton, and the flexible wrapping layer covers the exposed surface of the protective frame skeleton. The protective frame skeleton is made of elastic stainless steel, which has high strength and elasticity, and can generate appropriate deformation when subjected to force and return to its original shape after the external force disappears. The friction plate has a positioning groove inside that forms a self-locking engagement with the barb. The barb design of the barb makes it difficult for it to easily come out after being pushed into the positioning groove, ensuring the connection stability between the frame and the column.

[0006] Preferably, the friction pad includes a first friction pad disposed on the non-exposed end of the outer surface of the inner column and a second friction pad disposed on the inner surface of the end of the outer column, for maintaining the stability between the inner and outer columns and avoiding direct friction between the inner and outer columns.

[0007] Preferably, the friction plate is made of a high-friction coefficient composite material to further enhance the connection stability between the guard frame and the column. The inner wall of its positioning groove is provided with a guide slope corresponding to the movement trajectory of the hook, ensuring accurate positioning and smooth movement of the hook.

[0008] Preferably, a deformation compensation gap is provided between the protective frame skeleton and the flexible wrapping layer, and the barbs are distributed at intervals along the circumference of the protective frame skeleton.

[0009] Preferably, the number of positioning grooves of the barb and the friction plate are equal and correspondingly arranged, and the number of each is two or more.

[0010] Preferably, the friction plate is connected to the column via a quick-release structure, which includes a cooperating protrusion and a snap-fit ​​part, allowing it to be easily detached from the column.

[0011] Beneficial effects: Compared with the prior art, the present invention has the following advantages: The present invention achieves tool-free and convenient disassembly and assembly of the frame by the self-locking cooperation between the barb on the frame and the positioning groove of the friction plate. At the same time, the barb structure design of the barb can effectively prevent the frame from loosening, so that the frame has the characteristics of simple disassembly and assembly and high structural stability.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0024] like Figure 1-11 As shown, a telescopic column guard frame includes a frame 1 and a friction plate 2. The friction plate 2 is made of a high-friction coefficient composite material and is installed between the inner and outer columns of the telescopic column to form a buffer interface, preventing wear of the column caused by direct contact between the metal inner and outer columns. The frame 1 is located at the end of the outer column, providing column protection and support for the telescopic column, preventing damage from external collisions and friction during use. It also helps maintain the stability and straightness of the column, preventing debris from entering the gap between the inner and outer columns, thereby improving the service life and reliability of the column. The barbed part on the frame 1 extends into the gap between the inner and outer columns and cooperates with the positioning groove on the friction plate 2 located in the gap between the inner and outer columns to form a detachable connection with a self-locking function, preventing the frame 1 from loosening and falling off the end of the column.

[0025] The frame 1 consists of two parts: a protective frame skeleton 3 made of elastic stainless steel, possessing high strength and elasticity, capable of undergoing appropriate deformation under stress and returning to its original shape after the external force is removed; and a flexible wrapping layer 4 covering the exposed surface of the protective frame skeleton 3. A deformation compensation gap is provided between the two to buffer the deformation difference between the protective frame skeleton 3 and the flexible wrapping layer 4, preventing structural damage due to stress concentration, enhancing overall flexibility and durability, and adapting to complex working conditions. The flexible wrapping layer 4 fills the gaps in the columns and protects the protective frame skeleton 3, which serves as the main connecting component in conjunction with the friction plate 2. The barbs 5 are integrally formed with the ends of the protective frame skeleton 3, and are spaced apart circumferentially along the protective frame skeleton 3 to ensure uniform stress distribution. The barbs 5 and the positioning grooves of the friction plate 2 form a locking fit, with equal numbers and corresponding placement. The inner wall of the positioning groove is provided with a guide slope corresponding to the movement trajectory of the barb 5, which can easily push the barb 5 into the positioning groove of the friction plate 2. However, due to the influence of the barb shape structure and the restriction of the friction plate 2 and the tube wall, the barb 5 cannot be disengaged from its original direction of movement. The friction plate is divided into a first friction plate 6 and a second friction plate 7, which are respectively set on the non-exposed end of the inner column and the inner surface of the outer column end, to maintain the stability between the inner and outer columns and to avoid direct friction between the inner and outer columns. The friction plate 2 is connected to the column through a quick-release structure, which includes a mutually cooperating protrusion and a snap-fit ​​part, allowing for easy assembly and disassembly of the friction plate 2.

[0026] The working principle of the entire device is as follows: When the column guard frame needs to be installed, the first friction plate 6 and the second friction plate 7 are first installed at predetermined positions on the non-exposed end of the inner column and the inner surface of the outer column end, respectively, through a quick-release structure. This allows the inner and outer columns to slide together via the friction plate 2. Then, the barb 5 of the frame 1 is gradually pushed into the gap between the friction plate 2 and the outer column until the end face of the flexible wrapping layer 4 and the mating end face of the column outer tube achieve a sealed contact. As the barb 5 enters the positioning groove, it elastically resets after being released from the constraints of the friction plate 2 and the tube wall, and a rebound sound can be heard, indicating that the entire column tube and guard frame are assembled. When the guard frame structure needs to be disassembled, only the inner column needs to be retracted to release the spatial constraints of the friction plate 2, exposing the friction plate 2 on the inner wall of the outer column and removing it. Simultaneously, the self-locking state of the barb 5 is released to achieve overall disassembly.
