Description

Technical Field

[0001] This utility model relates to the field of shock absorber technology, specifically a controllable shock absorber. Background Technology

[0002] When installing ceiling-mounted air conditioners, axial flow fans, fresh air units, ducts, and other equipment, they often need to be suspended from the ceiling. Since these devices generate a certain amount of vibration and noise during operation, suspended vibration dampers are used as an auxiliary measure during installation. These dampers are installed between the ceiling and the equipment to provide vibration reduction and protection during operation.

[0003] The suspended shock absorber includes components such as an outer frame, top mount, base, hanger rod, and shock-absorbing spring. The bottom end of the hanger rod is connected to the equipment. However, the traditional top mount is slidably installed inside the outer frame, and the outer wall of the top mount does not have any device to limit or guide its movement. This means that the position of the top mount is only controlled by the shock-absorbing spring. Furthermore, due to the non-fixed position of the top mount, the deformation of the shock-absorbing spring cannot be effectively controlled. When the shock-absorbing spring has insufficient elasticity, the shock absorption effect of the suspended shock absorber on the supported equipment is weakened, and the shock absorption performance of the suspended shock absorber is quite limited. To address the shortcomings of the existing technology, we propose a controllable shock absorber to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a controllable shock absorber, which solves the problem of traditional top seats sliding inside the outer frame without any limiting or guiding devices on the outer wall of the top seat. This results in the top seat being controlled solely by the shock-absorbing spring for positional changes. Furthermore, due to the non-fixed position of the top seat, the deformation of the shock-absorbing spring cannot be effectively controlled. When the shock-absorbing spring has insufficient elasticity, the shock absorption effect of the suspended shock absorber on the supported equipment is weakened, leading to significant limitations in the shock absorption performance of the suspended shock absorber.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a controllable shock absorber, comprising an outer frame, a base fixedly disposed on the bottom surface of the outer frame, a top seat slidably disposed inside the outer frame, a suspension rod with one end disposed between the base and the top seat, and a shock-absorbing spring disposed between the base and the top seat. An adjustment mechanism is provided inside the outer frame, the adjustment mechanism comprising:

[0006] An auxiliary ring is fixedly installed on the outer wall of the top seat, and a guide rod for limiting the movement of the auxiliary ring is fixedly installed inside the outer frame;

[0007] An adjusting block, one end of which is sleeved on the outer wall of the guide rod, and the adjusting block is located on the upper part of the top seat;

[0008] An adjusting screw is rotatably mounted on the outer wall of the outer frame, and the range of movement of the top seat inside the outer frame is adjusted by the adjusting screw.

[0009] Preferably, a bearing is fixedly provided on the top surface of the adjusting block, and the outer wall of one end of the adjusting screw extending into the inner wall of the outer frame is fixedly connected to the inner wall of the bearing.

[0010] Preferably, an auxiliary telescopic rod is provided between the top surface of the adjusting block and the inner top surface of the outer frame.

[0011] Preferably, the top surface of the top seat is provided with a top block, and a buffer component is provided between the top block and the bottom surface of the adjusting block.

[0012] Preferably, the buffer assembly includes a groove formed on the bottom surface of the adjusting block, a buffer block slidably disposed inside the groove, and a buffer spring disposed inside the groove for elastic movement of the buffer block.

[0013] Preferably, a damper is provided between the inner wall of the groove and one side of the buffer block, and the buffer spring is sleeved on the outer wall of the damper.

[0014] Preferably, the top surface of the outer frame is provided with a hook.

[0015] This utility model discloses a controllable shock absorber, which has the following beneficial effects: This controllable shock absorber, by setting an adjusting block and adjusting screw at the outer frame of the suspended shock absorber, allows for the control of the movement range of the top seat within the outer frame, thereby correspondingly controlling the deformation of the shock-absorbing spring connected to the top seat, thus meeting the requirements of different shock absorption intensities of the shock-absorbing spring. In addition, combined with components such as guide rods, the deformation path of the adjusting block and the shock-absorbing spring is limited to prevent the shock-absorbing spring from deforming, thus ensuring the shock absorption effect of the suspended shock absorber.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] This application provides a controllable shock absorber that solves the problems of traditional top seats sliding inside the outer frame without any limiting or guiding devices on the outer wall, where the top seat's position is controlled solely by the shock-absorbing spring. Furthermore, the non-fixed position of the top seat makes it impossible to effectively control the deformation of the shock-absorbing spring. When the spring force is insufficient, the shock absorption effect of the suspended shock absorber on the supported equipment is weakened, resulting in significant limitations in its shock absorption performance. This invention achieves control over the deformation of the shock-absorbing spring force and limits the deformation path of the spring.

[0025] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0026] This utility model discloses a controllable shock absorber.

[0027] According to the appendix Figure 1-5As shown, the device includes an outer frame 1, a base 2 fixedly installed on the bottom surface of the inner side of the outer frame 1, a top seat 3 slidably installed inside the outer frame 1, a hanger 4 with one end located between the base 2 and the top seat 3, and a shock-absorbing spring 5 installed between the base 2 and the top seat 3. The shock-absorbing spring 5 is sleeved on the outer wall of the hanger 4. One end of the hanger 4 is fixedly connected to the bottom surface of the top seat 3. The end of the hanger 4 extending to the lower part of the outer frame 1 is connected to pipes or other equipment. A hook 11 is provided on the top surface of the outer frame 1. The outer frame 1 is securely connected to the ceiling through the hook 11. The outer frame 1, base 2, top seat 3, hanger 4, and shock-absorbing spring 5 constitute a suspended shock absorber required for suspending pipes and other equipment. In use, the hook 11 is first fixedly connected to the ceiling with screws or other fasteners. Then, the bottom end of the hanger 4 is fixedly connected to the frame supporting the pipes and other equipment with screws or other fasteners. When the pipe vibrates during use, the shock-absorbing spring 5 can buffer the vibration and prevent the force generated by the vibration from being directly transmitted to the ceiling, thus affecting the stability of the suspended pipe equipment.

[0028] See attached document Figure 2-4 An adjustment mechanism 6 is provided inside the outer frame 1. This mechanism controls the deformation of the damping spring 5. With a fixed spring constant, applying external force to the damping spring 5 increases its stretching or compression length; that is, the greater the deformation, the greater the elastic force generated by the damping spring 5. The adjustment mechanism 6 includes an auxiliary ring 61, which is fixedly mounted on the outer wall of the top seat 3. A guide rod 62 is fixedly mounted inside the outer frame 1 to limit the movement of the auxiliary ring 61. The guide rod 62 and the auxiliary ring 61 limit the elastic deformation path of the damping spring 5, preventing deformation. One end of an adjustment block 63 is sleeved on the outer wall of the guide rod 62, and the adjustment block 63 is located on the upper part of the top seat 3. An adjustment screw 64 is rotatably mounted on the outer wall of the outer frame 1. A bearing 641 is fixedly mounted on the top surface of the adjustment block 63. The outer wall of the end of the adjustment screw 64 extending into the inner part of the outer frame 1 is connected to the bearing 641. The inner wall of 41 is fixedly connected, and the adjusting screw 64 and the adjusting block 63 are always connected through the bearing 641. The auxiliary telescopic rod 65 is provided so that when the adjusting screw 64 is rotated, the adjusting block 63 will not rotate equally with the adjusting screw 64. The adjusting block 63 can only move up or down along the outer wall of the guide rod 62. The auxiliary telescopic rod 65 is provided between the top surface of the adjusting block 63 and the inner top surface of the outer frame 1. The moving range of the top seat 3 inside the outer frame 1 is adjusted by adjusting the adjusting screw 64. For example, by rotating the adjusting screw 64, the adjusting screw 64 controls the adjusting block 63 to move upward along the outer wall of the guide rod 62. At this time, the range of the top seat 3 between the adjusting block 63 and the base 2 increases, thereby increasing the deformation of the shock-absorbing spring 5 and enhancing the elasticity of the shock-absorbing spring 5. This improves the shock absorption capacity of the suspended shock absorber for the suspended pipeline equipment.

[0029] See attached document Figure 4-5 A top block 31 is provided on the top surface of the top seat 3. A buffer assembly 7 is provided between the top block 31 and the bottom surface of the adjusting block 63. The buffer assembly 7 reduces the impact intensity when the top seat 3 and the adjusting block 63 come into contact. The buffer assembly 7 includes a groove 71 formed on the bottom surface of the adjusting block 63, a buffer block 72 slidably disposed inside the groove 71, and a buffer spring 74 disposed inside the groove 71 for elastic movement of the buffer block 72. The diameter of the top block 31 is smaller than the diameter of the buffer block 72. A buffer is provided between the inner wall of the groove 71 and one side of the buffer block 72. A damper 73 is provided, and a buffer spring 74 is sleeved on the outer wall of the damper 73. Through the damper 73 and the buffer spring 74, before the top seat 3 contacts the bottom surface of the adjusting block 63 under the control of the damping spring 5, the top block 31 will contact the buffer block 72 first, so that the top block 31 compresses the damper 73 and the buffer spring 74, so that the damper 73 and the buffer spring 74 buffer the impact force generated by the top block 31, increase the safety of the adjusting block 63 during use, and improve the service life of the adjusting block 63 and the top seat 3.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
