Description

A durable shock absorber with good shock absorption effect Technical Field

[0001] This utility model relates to the field of shock absorption equipment technology, and in particular to a durable shock absorber with good shock absorption effect. Background Technology

[0002] Shock absorbers are devices used to reduce or eliminate vibration energy. They are widely used in machinery, vehicles, construction and other fields to protect equipment, structures and personnel safety, and improve precision and comfort.

[0003] Currently, shock absorbers on the market mainly adopt two structures: springs and airbags. Spring shock absorbers are simple in structure and low in cost, but they can only effectively reduce the vertical vibration of the equipment and are powerless against the front-back vibration. While airbag shock absorbers can solve the problem of front-back vibration, their high cost is usually ten times that of spring shock absorbers. When the equipment must be placed on the floor, users have no choice but to choose airbag shock absorbers, which undoubtedly increases the investment cost. Summary of the Invention

[0004] One objective of this invention is to provide a durable shock absorber with good vibration reduction effect. This invention addresses the issue mentioned above, where current shock absorbers on the market mainly employ two structures: springs and airbags. Spring shock absorbers are simple in structure and low in cost, but they can only effectively reduce vertical vibrations of equipment and are powerless against front-to-back vibrations. While airbag shock absorbers can solve the problem of front-to-back vibrations, their high cost is usually ten times that of spring shock absorbers. When equipment must be placed on a floor slab, users have no choice but to choose airbag shock absorbers, which undoubtedly increases the investment cost.

[0005] A durable shock absorber with good damping effect according to an embodiment of the present utility model includes:

[0006] The protective assembly includes a protective lower plate installed at the bottom or below the equipment, which is adjusted by a screw to support part of the weight of the equipment on the shock absorber. A protective outer cover is fixedly installed on the top of the protective lower plate by a first connecting assembly, and a protective cover plate is fixedly installed on the top of the protective outer cover by a second connecting assembly.

[0007] A shock-absorbing assembly is installed between the lower protective plate and the outer protective shell in the protective assembly. It is used to reduce or eliminate the vibration of the equipment through the shock absorber. The shock-absorbing assembly includes a damper fixedly installed on the top of the lower protective plate by a third connecting assembly. The damping end of the damper is fixedly installed with a lower positioning cup by a fourth connecting assembly. The top of the lower positioning cup is connected to an upper positioning cup by a main spring. The top of the upper positioning cup is fixedly installed with a positioning seat by a fifth connecting assembly. A return spring is sleeved on the outside of the positioning seat. A positioning sleeve located between the protective cover plate and the outer protective cylinder is sleeved on the upper end of the outside of the positioning seat.

[0008] Preferably, the first connecting component includes a first threaded seat fixed to the top of the lower protective plate, and the first threaded seat and the protective outer sleeve are fixed by threads.

[0009] Preferably, the second connecting component includes a second threaded seat fixed to the top of the protective cover, and the second threaded seat and the protective cover are fixed by threads.

[0010] Preferably, a shock-absorbing pad is fixedly provided on the outer side of the lower protective plate.

[0011] Preferably, the third connecting assembly includes a third threaded seat fixed to the top of the lower protective plate, and the third threaded seat and the damper are fixedly connected by threads.

[0012] Preferably, the fourth connecting component includes a fourth threaded seat fixed to the damping end of the damper, and the fourth threaded seat and the lower positioning cup are fixed by threads.

[0013] Preferably, the fifth connecting component includes a fifth threaded seat fixed to the bottom of the positioning seat, and the fifth threaded seat and the upper positioning cup are fixed by threads.

[0014] Preferably, the reset spring is located between the positioning seat and the positioning sleeve.

[0015] The beneficial effects of this utility model are:

[0016] This invention effectively avoids the problems of traditional spring shock absorbers being unable to suppress forward and backward vibrations, and airbag shock absorbers being too expensive, by setting up protective and shock-absorbing components. In use, the protective component forms a closed protective space through the protective lower plate, protective outer shell, and protective cover plate. The shock-absorbing component is installed between the protective lower plate and the protective outer shell, effectively protecting the internal shock-absorbing component from external environmental corrosion and damage, and extending the service life of the shock absorber. The damper in the shock-absorbing component is connected to the lower positioning cup through its shock-absorbing end, and connected to the upper positioning cup through the main spring, forming a vertical shock-absorbing system that can effectively absorb and alleviate the vertical vibration of the equipment. At the same time, the return spring sleeved on the outside of the positioning seat and the upper positioning sleeve work together to form a horizontal shock-absorbing system that can effectively absorb and alleviate the forward and backward vibration of the equipment. Through the combined vertical and horizontal shock absorption, not only can the vertical vibration of the equipment be effectively reduced, but the forward and backward vibration of the equipment can also be effectively reduced. This effectively avoids the technical problem of existing spring shock absorbers that can only reduce vertical vibration but not forward and backward vibration, and also overcomes the disadvantage of high cost of airbag shock absorbers, reducing the user's investment cost.

[0017] This invention effectively avoids the maintenance difficulties of traditional shock absorbers by using a specially designed connecting component. During use, the entire shock absorber can be quickly assembled and disassembled through the threaded seat in the connecting component, reducing the inconvenience of disassembly and assembly during maintenance caused by bolt installation. This allows the shock absorber to maintain stable damping performance during long-term use, effectively avoiding the problem of reduced damping effect or failure caused by loose connections in existing shock absorbers. At the same time, this stable connection method also enhances the durability of the shock absorber and extends its service life. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] Referring to Figures 1-4, a durable shock absorber with good damping effect includes:

[0026] The protective component 1 includes a lower protective plate 101 installed at the bottom or below the equipment. The lower plate 101 is adjusted by a screw to support part of the equipment's weight on the shock absorber. A protective outer jacket 103 is fixedly installed on the top of the lower protective plate 101 via a first connecting component. A protective cover plate 105 is fixedly installed on the top of the protective outer jacket 103 via a second connecting component. The lower protective plate, the protective outer jacket, and the protective cover plate form a closed protective space, which is used to install the shock absorber between the lower protective plate and the protective outer jacket. This effectively protects the internal shock absorber from external environmental corrosion and damage, and extends the service life of the shock absorber.

[0027] The vibration damping assembly 2 is installed between the lower protective plate 101 and the protective shell in the protective assembly 1. It is used to reduce or eliminate equipment vibration through the damper. The vibration damping assembly 2 includes a damper 201 fixedly installed on the top of the lower protective plate 101 via a third connecting assembly. A lower positioning cup 203 is fixedly installed on the damping end of the damper 201 via a fourth connecting assembly. An upper positioning cup 205 is connected to the top of the lower positioning cup 203 via a main spring 204. A positioning seat 206 is fixedly installed on the top of the upper positioning cup 205 via a fifth connecting assembly. A return spring 208 is sleeved on the outside of the positioning seat 206. A positioning element located on the protective cover plate 105 and the lower positioning cup 205 is sleeved on the upper end of the positioning seat 206. The positioning sleeve 209 between the protective outer cylinders, the damper in the shock absorption assembly is connected to the lower positioning cup through its shock absorption end, and connected to the upper positioning cup through the main spring, forming a vertical shock absorption system that can effectively absorb and mitigate the vertical vibration of the equipment. At the same time, the return spring sleeved on the outside of the positioning seat and the upper positioning sleeve work together to form a horizontal shock absorption system that can effectively absorb and mitigate the front and rear vibration of the equipment. Through the combined vertical and horizontal shock absorption, not only can the vertical vibration of the equipment be effectively reduced, but the front and rear vibration of the equipment can also be effectively reduced, thus effectively avoiding the technical problem of existing spring shock absorbers that can only reduce vertical vibration but not front and rear vibration.

[0028] Example 1: The first connecting assembly includes a first threaded seat 102 fixed to the top of the lower protective plate 101, and the first threaded seat 102 and the protective outer sleeve 103 are threadedly fixed together. The second connecting assembly includes a second threaded seat 104 fixed to the top of the protective outer sleeve 103, and the second threaded seat and the protective cover plate 105 are threadedly fixed together. The third connecting assembly includes a third threaded seat 106 fixed to the top of the lower protective plate 101, and the third threaded seat 106 and the damper 201 are threadedly fixed together. The fourth connecting assembly includes a first threaded seat 104 fixed to the damping end of the damper 201. The fourth threaded seat 202 and the lower positioning cup 203 are fixed by threads. The fifth connecting component includes a fifth threaded seat 207 fixed to the bottom of the positioning seat 206. The fifth threaded seat 207 and the upper positioning cup 205 are fixed by threads. The entire shock absorber can be quickly assembled and disassembled through the threaded seats in the connecting component, which can reduce the inconvenience of disassembly and assembly during maintenance due to bolt installation. This allows the shock absorber to maintain stable damping performance during long-term use and effectively avoids the problem of reduced damping effect or failure of existing shock absorbers due to loose connections.

[0029] Example 2: A shock-absorbing pad 107 is fixedly installed on the outer side of the protective lower plate 101, and a reset spring 208 is located between the positioning seat 206 and the positioning sleeve 209, providing additional vibration absorption and reset functions.

[0030] Working principle: First, the equipment's weight is partially supported by the shock absorber via screw adjustment. The equipment's vibration energy is transmitted to the positioning seat 206 through the protective cover plate 105. The positioning seat 206 compresses the return spring 208, causing horizontal deformation and absorbing the equipment's front-to-back vibration. The vibration energy is then transmitted through the upper positioning cup 205 to the lower positioning cup 203 via the main spring 204. The lateral elastic deformation of the main spring 204 further suppresses the front-to-back vibration. The lower positioning cup 203 transmits the vertical vibration to the damper 201. The damper 201 dissipates the vertical vibration energy through damping. The residual vibration is transmitted to the lower protective plate 101. The damper on the outside of the lower protective plate 101... The shock absorber 107 absorbs the final residual vibration. After the vibration is eliminated, the return spring 208 pushes the positioning seat 206 to reset. Throughout the process, the sealed space formed by the lower protective plate 101, the outer protective jacket 103, and the protective cover plate 105 prevents external contaminants from corroding the core components. Therefore, the shock absorber has a much better shock absorption effect than the spring shock absorber. It can achieve the effect of the airbag shock absorber and has a service life several times longer than the airbag shock absorber. It solves the problem that the spring shock absorber cannot reduce the front and rear vibrations. It improves the shock absorption effect compared to the spring shock absorber and also solves the problem that the airbag shock absorber is prone to aging and has a short service life. It has a longer service life than the airbag shock absorber.

[0031] 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.
