Description

Technical Field

[0001] This utility model relates to the field of damper technology, specifically a unidirectional metal damper. Background Technology

[0002] In practical applications, the effective damping position of existing unidirectional metal dampers is usually fixed, making it impossible to flexibly adjust the corresponding position of the damping action according to different load requirements, installation space limitations, and other actual usage conditions. This results in insufficient adaptability and flexibility of the damper, making it difficult to fully realize the damping energy dissipation effect. At the same time, if the structure of the unidirectional metal damper is modified to achieve adjustable damping, the overall structure of the damper will often become more complex. The disassembly and assembly process requires special tools and multiple cumbersome procedures, which not only leads to low disassembly and assembly efficiency but also easily damages the damper's main structure and connection parts during disassembly and assembly, thereby weakening or failing the damping performance. Furthermore, it is difficult to easily disassemble, maintain, repair, or replace the damper when a failure occurs later, significantly increasing the cost of use and operation.

[0003] Therefore, it is necessary to develop a unidirectional metal damper. Utility Model Content

[0004] The purpose of this invention is to provide a unidirectional metal damper to solve the problems mentioned in the background art.

The auxiliary component includes a positioning ring, and bolts A are installed on both sides of the outer wall of the positioning ring.

[0006] Preferably, a nut is installed on one side of the outer wall of the output shaft, and the inside of the nut is threadedly connected to the outer wall of the output shaft.

[0007] Preferably, one outer wall of the scale positioning seat is fixedly mounted on the outer wall of the unidirectional damper, and positioning holes are provided on the surface of the scale positioning seat.

[0011] Preferably, the interior of the positioning ring is slidably connected to the outer wall of the one-way damper and the scale positioning seat, and the outer wall of the bolt A is threadedly connected to the interior of the two outer walls of the positioning ring.

[0012] Preferably, a fixing ring is installed on the end face of the positioning ring, and bolts B are threadedly connected to the four positions of the end face of the fixing ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This unidirectional metal damper uses a sliding fit between the limit frame, guide column, and guide ring, along with a nut for limiting, to ensure structural stability during damping and prevent the limit frame from detaching. The scale markings and positioning hole design of the scale positioning seat, combined with the locking of the positioning ring and bolt A, allow for precise adjustment of the damping buffer distance, adapting to different load and installation space requirements and significantly improving the damper's usability.

[0014] The overall structure adopts a modular and detachable design, which can complete the disassembly and assembly of each component without special tools. This makes it convenient to operate during later maintenance, repair or component replacement, avoiding damage to the damper body during disassembly and assembly and reducing operation and maintenance costs. At the same time, the adjustment and fixing process is simple and efficient, without complicated procedures, further enhancing the practicality and ease of operation of the equipment.

Bolts B403 are threadedly connected to the four positions of the end face of the fixing ring 402.

[0020] The unidirectional damper 1 is the core damping component, made of metal, and has the function of unidirectional damping energy dissipation. One end of it is fixedly installed with an output shaft 101 by a coupling or welding. The output shaft 101 is a cylindrical metal shaft used to transmit damping force and install the limiting structure.

[0021] A nut 102 is threaded onto one side of the outer wall of the output shaft 101. The nut 102 is a metal nut with anti-slip texture, used to axially limit the limit frame 3. A guide ring 2 is bolted to one side of the outer wall of the unidirectional damper 1. The guide ring 2 is an annular metal part with four evenly distributed guide holes inside, used to cooperate with the sliding of the guide post 301.

[0022] The guide ring 2 has a scale positioning seat 201 symmetrically welded to the front and rear ends of one side. The outer wall of the scale positioning seat 201 is tightly fitted and fixed to the outer wall of the one-way damper 1. The surface is engraved with clear distance scales and has evenly opened positioning holes 202. The positioning holes 202 are threaded holes used to lock the position of the positioning ring 4.

[0023] A limit frame 3 is slidably mounted on the outer wall of the output shaft 101. The limit frame 3 is a ring-shaped metal frame, which is slidably connected to the outer wall of the output shaft 101 with a clearance, and can move along the axial direction of the output shaft 101. Guide posts 301 are symmetrically welded to four positions on one side of the outer wall of the limit frame 3. The guide posts 301 are cylindrical metal rods, and their outer walls are slidably connected to the guide holes of the guide ring 2 to ensure that the limit frame 3 moves smoothly.

[0024] A spring 302 is fitted on one side of the outer wall of the guide post 301. The spring 302 is located between the guide ring 2 and the limit frame 3, providing elastic support for the limit frame 3 and assisting in damping and buffering reset. One end of the guide post 301 has a threaded hole 303 for connecting the fixing ring 402.

[0025] An auxiliary component is installed on the other side of the outer wall of the unidirectional damper 1. The core component is the positioning ring 4, which is a ring-shaped metal part. It is slidably connected to the outer wall of the unidirectional damper 1 and the scale positioning seat 201 and can move axially along the scale positioning seat 201. Bolts A401 are threadedly connected to both outer walls of the positioning ring 4. Bolts A401 are manual bolts, one end of which can be screwed into the positioning hole 202 of the scale positioning seat 201 to fix the positioning ring 4.

[0026] A fixing ring 402 is bolted to the end face of the positioning ring 4. The fixing ring 402 is an annular metal plate with bolts B403 threaded to all four positions on its end face. One end of the bolts B403 is threaded to the threaded hole 303 of the guide post 301, thus achieving a stable connection between the fixing ring 402 and the guide post 301.

[0027] Working principle: When using this utility model, the damper is first assembled: the limiting frame 3 is slidably mounted from the free end of the output shaft 101, so that the four sets of guide posts 301 on one side of the limiting frame 3 are respectively inserted into the four guide holes of the guide ring 2, ensuring that the limiting frame 3 can slide smoothly along the output shaft 101 and the guide posts 301. The spring 302 is mounted on the outer wall of the guide post 301, so that it is located between the guide ring 2 and the limiting frame 3. Then, the nut 102 is screwed into one side of the outer wall of the output shaft 101 and tightened until it is in close contact with the other side of the limiting frame 3, thus completing the limiting and fixing of the limiting frame 3 and preventing it from detaching from the output shaft 101.

[0028] Slide the positioning ring 4 from the end of the one-way damper 1, so that its inner wall fits against the outer wall of the one-way damper 1 and the scale positioning seat 201, and slide it to the position corresponding to the guide post 301. Fit the fixing ring 402 against the end face of the positioning ring 4, align it with the threaded hole 303 at one end of the guide post 301, screw in the bolt B403 and tighten it, so as to realize the integrated connection of the fixing ring 402, the positioning ring 4 and the guide post 301.

[0029] Adjust the damping buffer distance according to the on-site usage requirements: Observe the scale on the surface of the scale positioning seat 201, manually pull the positioning ring 4, the positioning ring 4 drives the guide column 301 and the limit frame 3 to move synchronously along the axis until the preset buffer distance is reached. At this time, align the bolts A401 on both sides of the positioning ring 4 with the corresponding positioning holes 202 on the scale positioning seat 201, tighten the bolts A401 so that one end is screwed into the positioning hole 202, complete the locking of the positioning ring 4, and fix the damping buffer distance.

[0030] When the damper is working, the output shaft 101 transmits external force, the limit frame 3 slides along the output shaft 101 and the guide post 301, the spring 302 assists in buffering and resetting, the one-way damper 1 plays a one-way damping and energy dissipation role, and the movement range of the limit frame 3 is limited to the preset buffer distance by the positioning ring 4.

[0031] For later maintenance, repair, or replacement of parts, simply loosen bolts A401, B403, and nut 102 in sequence to disassemble components such as positioning ring 4, fixing ring 402, and limit bracket 3. After maintenance, repair, or replacement, reassemble in reverse order. No special tools are required throughout the process, making it easy to operate.

[0032] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
