Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a damper that can be disassembled and maintained on site. Background Technology
[0002] A damper is a device that dissipates kinetic energy by providing resistance. In the field of modern engineering, dampers are a crucial device that can effectively absorb or reduce structural vibrations, protect structures from damage, and provide key guarantees for the stable operation of various building and mechanical systems. The working principle of dampers is based on physical phenomena and mechanical structure design.
[0003] A damper is a device that uses the movement of a liquid to generate damping force. During the flow of a liquid, it will pass through pores, gaps or specific channels. Due to the viscosity of the liquid, frictional resistance will be generated during the flow. This frictional resistance will hinder the movement of the liquid, thereby converting the kinetic energy of the structure into heat energy, thus achieving the purpose of consuming energy and reducing vibration. Traditional integrated damper designs are not easy to disassemble and are easily damaged by violent use. Utility Model Content

[0032] 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.
[0033] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of a damper that can be disassembled and maintained on-site, comprising a lower section tube 1. A disassembly mechanism 2 is installed at the top of the lower section tube 1. The disassembly mechanism 2 facilitates the disassembly and assembly of the device. A limiting mechanism 3 is installed on the outer wall of the disassembly mechanism 2 to limit the range of motion of the device and prevent overuse. The disassembly mechanism 2 includes a housing 204, which is installed on the top left and right sides of the lower section tube 1. A rotating shaft 206 is fixedly connected to the upper middle part of the inner wall of the housing 204, and a movable connecting rod is rotatably connected to the outer wall of the rotating shaft 206. A telescopic push rod 205 is fixedly connected to the lower part of the inner wall of the plate 207 and the outer shell 204. An upper section pipe 201 is installed on the top of the lower section pipe 1. A push block 203 is installed on the front side of the outer wall of the upper section pipe 201. A docking groove 202 is opened at the bottom of the upper section pipe 201. The lower section pipe 1 is slidably connected to the inside of the docking groove 202. An installation hole 4 is opened on the outer wall of the upper section pipe 201. The installation hole 4 is equidistantly opened on the outer wall of the upper section pipe 201. An installation hole 6 is opened on the outer wall of the lower section pipe 1.
[0034] Specifically, during pipe connection and installation, the ports of the upper pipe section 201 and the lower pipe section 1 must first be precisely aligned to ensure their central axes remain consistent, laying the foundation for a stable connection. After alignment, operate the outer casing 204 installed on the left and right sides of the lower pipe section 1, aligning it with the corresponding docking groove 202 on the upper pipe section 201 and slowly inserting it. As the outer casing 204 extends deeper into the docking groove 202, maintaining a smooth operation is crucial. When the outer casing 204 reaches the top of the docking groove 202, activate the preset telescopic push rod 205. At this time, the flap 207, rotatably connected to the outer wall of the rotating shaft 206, will flip outwards under the thrust of the telescopic push rod 205 until it is fully inserted into the slot inside the docking groove 202. Through the tight engagement of the flap 207 and the slot, the upper pipe section 201 and the lower pipe section 1 are securely fixed, ensuring the stability of the pipe connection. If disassembly is required, simply press the button 203 on the lower pipe section 1. When button 203 is triggered, it transmits force to push flap 207. At the same time, telescopic push rod 205 initiates the retraction procedure, pulling flap 207 back to its original position from the slot in docking groove 202. As flap 207 is retracted, the fixed state between upper section pipe 201 and lower section pipe 1 is released, and the connection becomes loose. At this time, upper section pipe 201 can be smoothly pulled out from lower section pipe 1, completing the entire disassembly process of the equipment. The interaction and use of the equipment are improved through mounting hole 1 4 and mounting hole 2 6.
[0035] Reference Figure 1 , Figure 6 and Figure 7 The limiting mechanism 3 includes a connecting arm 301, which is installed on the upper part of the outer wall of the upper section pipe 201. A connecting button 302 is rotatably connected to the right side of the connecting arm 301. A connecting tooth 307 is fixedly connected to the right end of the connecting arm 301. A spring 303 is fixedly connected to the lower end of the connecting arm 301. A connecting arm 304 is fixedly connected to the other end of the spring 303. A connecting arm 305 is rotatably connected to the connecting arm 304. Another connecting button 302 is rotatably connected to the connecting arm 305. Another spring 303 is fixedly connected to the lower end of the connecting arm 305. A connecting arm 306 is fixedly connected to the other end of the spring 303. The connecting arm 306 is rotatably connected to the connecting arm 301. A lower lifting ring 8 is fixedly connected to the bottom of the lower section pipe 1. A rubber ring 14 is installed inside the lower lifting ring 8. An upper lifting ring 12 is fixedly connected to the top of the piston rod 11. A rubber ring 13 is installed inside the upper lifting ring 12.
[0036] Specifically, in the initial stage of the entire movement process, the piston rod 11 moves downward first. This action directly drives the connected connecting arms 301 and 306 to move downward synchronously. Simultaneously, under the linkage of the connecting structure, connecting arms 305 and 304 move upward. This securely connects connecting arms 306 and 305, ensuring a coordinated force relationship during movement. Another set of connecting buttons 302 tightly connects connecting arms 301 and 304, forming a stable integrated structure. Through this connection method, the entire movable frame is firmly fixed, limiting the maximum downward movement of the piston rod 11 and preventing it from exceeding the preset range due to excessive movement, thus ensuring the safety of equipment operation. After completing the downward stroke, the piston rod 11 begins to move upward, entering the pull-up and reset stage. At this time, the spring 303, pre-installed in the structure, releases its elastic potential energy, generating an upward elastic force, effectively accelerating the reset speed of the piston rod 11. This design allows the piston rod 11 to quickly return to its initial position, thereby better adapting to the frequency requirements of high-speed operation of the equipment and ensuring that the entire mechanical structure maintains a stable and efficient operating state during high-frequency motion. The operation of the equipment is improved by the lower lifting ring 8 and the upper lifting ring 12.
[0037] Reference Figure 1 , Figure 2 and Figure 3 The upper section pipe 201 has a piston rod 11 slidably connected inside, and a working piston 10 is fixedly connected to the bottom of the piston rod 11. The lower section pipe 1 has a nameplate 5 installed on its outer wall, and a floating piston 9 is installed inside its interior.
[0038] Specifically, the working piston 210 is used to reduce speed, the nameplate 5 marks the equipment, and the floating piston 19 resets the working piston 210.
[0039] Working principle: First, align the upper section pipe 201 and the lower section pipe 1. Then, the outer shell 204 installed on the left and right sides of the lower section pipe 1 is inserted into the docking groove 202. When it reaches the top of the docking groove 202, the movable plate 207, which is rotatably connected to the outer wall of the rotating shaft 206, is pushed out by the telescopic push rod 205. The movable plate 207 enters the groove to fix the upper section pipe 201 and the lower section pipe 1. Finally, press the button 203 to push the movable plate 207. The telescopic push rod 205 retracts it, so that the connection between the upper section pipe 201 and the lower section pipe 1 is loosened and it can be pulled out to complete the disassembly of the equipment.
[0040] First, the piston rod 11 moves downward, causing connecting arm 1 301 and connecting arm 4 306 to move downward, while connecting arm 3 305 and connecting arm 4 306 move upward. Connecting arm 4 306 and connecting arm 305 are connected by connecting button 302, and connecting arm 1 301 and connecting arm 2 304 are connected by connecting button 302. The movable frame is fixed, limiting the maximum position of piston rod 11. Finally, piston rod 11 moves upward, causing it to be pulled up and reset. Spring 303 accelerates the reset speed to adapt to the frequency of high-speed movement.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
