Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a retractable column with elastic support. Background Technology

[0002] In modern industry and construction, many devices and structures require height adjustment capabilities and the ability to maintain stability and comfort under dynamic loads. For example, in areas such as machinery installation, furniture manufacturing, and building support, there is often a need for support systems that can adapt to different height requirements and effectively absorb vibrations.

[0003] However, existing retractable column masts still have some technical problems. First, the shock absorption mechanisms in many existing designs are not perfect, and the selection and layout of the cushioning materials are unreasonable, resulting in unsatisfactory vibration reduction effects, difficulty in effectively absorbing vibration energy, and easy induction of resonance, affecting the stability and service life of the equipment. Second, the height adjustment mechanism is usually quite complex and inconvenient to operate. Users need to disassemble multiple parts or apply considerable force when adjusting the height, increasing the difficulty of operation and time costs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a retractable vertical support column with elastic support.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A retractable support column with elastic support includes a fixed column, a second groove at the upper end of the fixed column, a sleeve column connected to the second groove through a shock-absorbing mechanism, a first groove at the upper end of the sleeve column, a movable column slidably disposed in the first groove, a plurality of positioning holes sequentially formed on both sides of the movable column, and positioning mechanisms connected to two positioning holes respectively on both sides of the sleeve column.

[0007] As a further improvement of this utility model, the shock absorption mechanism includes two buffer pads disposed in the second groove. One of the two buffer pads is fixedly connected to the lower end of the sleeve column, and the other is fixedly connected to the inner bottom of the second groove. A second spring is provided between the two buffer pads, and the two ends of the second spring are respectively fixedly connected to the two buffer pads.

[0008] As a further improvement of this utility model, the positioning mechanism includes a support frame fixedly connected to one side of the sleeve column. The support frame is provided with a positioning column. One end of the positioning column passes through the first groove and is inserted into a positioning hole. The other end of the positioning column passes through the support frame and is fixedly connected to a pull plate. A sleeve plate is fixedly sleeved on the positioning column. A third spring sleeved with the positioning column is fixedly connected to the sleeve plate. The other end of the third spring is fixedly connected to the inner wall of the support frame.

[0009] As a further improvement of this utility model, a damper is inserted inside the second spring, and the two ends of the damper are respectively fixedly connected to two buffer pads.

[0010] As a further improvement of this utility model, a first spring is fixedly connected to the bottom of the first groove, and the other end of the first spring is fixedly connected to the lower end of the movable column.

[0011] As a further improvement of this utility model, both cushioning pads are made of rubber.

[0012] The beneficial effects of this utility model are:

[0013] By placing two rubber buffer pads within the second groove, and configuring a second spring and damper between them, the vibration damping effect is significantly improved. The rubber buffer pads not only have good elasticity and wear resistance, but also effectively absorb vibration energy and reduce vibration. The second spring provides additional elastic support, while the damper further reduces resonance, ensuring the stability and reliability of the entire vibration damping mechanism under various operating conditions. This effectively solves the problem of unsatisfactory vibration damping effect in traditional vibration damping mechanisms and extends the service life of the equipment.

[0014] By incorporating a positioning mechanism, the height of the movable column can be easily adjusted simply by pulling the pull plate on the mechanism, causing the positioning pin to extend from the positioning holes on both sides of the movable column. Once adjusted, releasing the pull plate allows the third spring to automatically insert the positioning pin into the corresponding positioning hole, thus fixing the height. This eliminates the need for complex disassembly and applying significant external force, simplifying the operation, reducing operational difficulty and time costs, and improving the user experience.

[0015] This invention significantly improves the shock absorption effect, extends the service life of the equipment, and at the same time, by simplifying the operation steps, it reduces the difficulty and time cost of operation and improves the user experience. Attached Figure Description

[0020] 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.

[0021] Figures 1-3 A retractable support column with elastic support includes a fixed column 1. The upper end of the fixed column 1 has a second groove 15. A sleeve column 2 is connected to the second groove 15 through a shock-absorbing mechanism. The shock-absorbing mechanism includes two buffer pads 6 set in the second groove 15. Both buffer pads 6 are made of rubber, which not only has good elasticity and wear resistance, but also effectively absorbs vibration energy. One of the two buffer pads 6 is fixedly connected to the lower end of the sleeve column 2, and the other is fixedly connected to the inner bottom of the second groove 15. A second spring 7 is provided between the two buffer pads 6. The two ends of the second spring 7 are fixedly connected to the two buffer pads 6 respectively. A damper 8 can effectively absorb vibration energy, further reduce resonance, and improve the stability of the entire shock-absorbing mechanism. The damper 8 is inserted into the second spring 7, and the two ends of the damper 8 are fixedly connected to the two buffer pads 6 respectively.

[0022] A first groove 14 is formed at the upper end of the sleeve 2, and a movable column 3 is slidably disposed within the first groove 14. To ensure the smooth sliding of the movable column 3 within the first groove 14, a lubricating coating is added to the inner wall of the first groove 14 or a material with a low coefficient of friction is used to reduce friction and extend service life. A first spring 5 is fixedly connected to the bottom of the first groove 14, and the other end of the first spring 5 is fixedly connected to the lower end of the movable column 3. The first spring 5 is made of high-strength spring steel, has good elasticity and fatigue resistance, and can maintain stable support force during multiple compressions and rebounds, ensuring the stability and reliability of the movable column 3 under different loads. Multiple positioning holes 4 are sequentially formed on both sides of the movable column 3. These positioning holes 4 are evenly distributed on both sides of the movable column 3, providing multiple height... The adjustable options allow users to easily adjust the height of the column according to their actual needs. The sleeve column 2 has positioning mechanisms on both sides that connect to two positioning holes 4. Each positioning mechanism includes a support frame 9 fixedly connected to one side of the sleeve column 2. A positioning column 10 is located inside the support frame 9. One end of the positioning column 10 passes through a first groove 14 and is inserted into a positioning hole 4. The other end of the positioning column 10 passes through the support frame 9 and is fixedly connected to a pull plate 13. A sleeve plate 11 is fixedly fitted onto the positioning column 10. A third spring 12, fitted onto the positioning column 10, is fixedly connected to the sleeve plate 11. The other end of the third spring 12 is fixedly connected to the inner wall of the support frame 9. The function of the third spring 12 is to provide a certain preload, ensuring that the positioning column 10 is firmly inserted into the positioning hole 4 and can be easily pulled out when height adjustment is needed. The pull plate 13 is designed for easy manual operation; by pulling the pull plate 13, the positioning column 10 can be pulled out of the positioning hole 4, thereby adjusting the height of the movable column 3.

[0023] When using this utility model, the height of the movable column 3 is adjusted as needed, and the pull plate 13 on the positioning mechanism is pulled to make the positioning column 10 be pulled out from the positioning holes 4 on both sides of the movable column 3; then, after moving the movable column 3 up and down to the required height, the pull plate 13 is released, and the positioning column 10 will automatically insert into the corresponding positioning hole 4 under the action of the third spring 12 to complete the height fixation.

[0024] During the support process, when subjected to vibration, the buffer pad 6 and the second spring 7 in the shock absorption mechanism absorb the vibration, while the damper 8 further reduces resonance, ensuring the stability and comfort of the movable column 3.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
