Description

Technical Field

[0001] The invention belongs to the technical field of shock absorber equipment, and in particular relates to a quick return shock absorber. Background Art

[0002] Shock absorbers are widely used in various equipment industries such as military and civilian. From the perspective of structural form, they are mainly divided into two categories: rubber shock absorbers and spring shock absorbers. In addition, in order to consider the damping effect of the system, an oil circuit is added inside the structure to produce a damping effect. Rubber shock absorbers are mainly used in medium-to-high load and medium-to-high frequency applications, spring shock absorbers are generally used in low-to-medium frequency and low-to-medium load applications, and hydraulic dampers can improve the damping effect of the system and further reduce the vibration of the system. In short, rubber shock absorbers and spring shock absorbers have their own application scenarios.

[0003] However, key equipment in warships and large ships have special requirements for vibration reduction: for example, large navigation instruments in warships require high stiffness, high damping and rapid return of shock absorbers. Such requirements are mainly to cope with strong external impacts (such as sudden collisions or artillery shell attacks). The currently commonly used rubber shock absorbers or spring shock absorbers do not have the characteristics of high stiffness, high damping and rapid return without adding additional dampers. Summary of the invention

[0004] In order to solve the defect in the prior art that the shock absorber cannot return quickly when subjected to external force, the present invention provides a quick return shock absorber.

[0005] The technical solution of the present invention is as follows:

[0006] The invention provides a quick return shock absorber, comprising a shock absorbing part, an upper mounting seat and a lower mounting seat with the same structure, wherein the shock absorbing part is sandwiched between the upper mounting seat and the lower mounting seat.

[0007] The lower mounting seat is provided with a first mounting hole arrayed along the center circumference thereof and a second mounting hole arrayed along the center circumference of the lower mounting seat and arranged outside the first mounting hole.

[0008] The vibration reduction unit is composed of 24 vibration reduction rods.

[0009] In the embodiment provided by the present invention, the above-mentioned lower mounting seat is provided with 12 first mounting holes and 12 second mounting holes, and the first mounting holes on the lower mounting seat and the upper mounting seat correspond one to one, and the second mounting holes on the lower mounting seat and the upper mounting seat correspond one to one.

[0010] In the embodiment provided by the present invention, one end of the vibration damping rod is clamped with the first mounting hole or the second mounting hole on the lower mounting seat, and the other end of the vibration damping rod is clamped with the corresponding first mounting hole or the second mounting hole on the upper mounting seat.

[0011] In the embodiment provided by the present invention, the above-mentioned vibration-damping rod comprises an upper rod, a lower rod and a damping spring, and the above-mentioned upper rod and the above-mentioned lower rod are connected via the above-mentioned damping spring.

[0012] In the embodiment provided by the present invention, the free ends of the lower rod and the upper rod are both provided with an integrally formed connecting ball.

[0013] In the embodiment provided by the present invention, the damping spring is a double U-shaped structure, and both ends of the damping spring are provided with mounting protrusions for connecting with the upper rod or the lower rod.

[0014] Beneficial effects: The quick return shock absorber provided by the present invention has a simple structure and is easy to maintain. A damping spring made of a high manganese-based damping alloy is used to design a shock absorber rod with high damping performance, and a combination of circumferentially mounted shock absorber rods is used to enable the quick return shock absorber to have high stiffness and high damping characteristics while being able to return quickly, ensuring that the equipment can operate normally and quickly while achieving good shock absorption effects. Secondly, the present invention utilizes a damping spring for vibration reduction and resetting, so that the quick return shock absorber has a higher damping effect without the need for oil to achieve the damping effect. Compared with shock absorbers with traditional external dampers, the design is simplified and the cost is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example:

[0026] like Figure 1 As shown, this embodiment provides a quick return shock absorber 1, comprising a shock absorbing part 2, an upper mounting seat 3 and a lower mounting seat 4 having the same structure, wherein the shock absorbing part 2 is sandwiched between the upper mounting seat 3 and the lower mounting seat 4.

[0027] like Figure 2As shown, the lower mounting seat 4 is provided with a first mounting hole 40 arranged in an array along the center and circumference of the circle, and a second mounting hole 42 arranged in an array along the center and circumference of the circle of the lower mounting seat 4 on the periphery of the first mounting hole 40. Since the upper mounting seat 3 and the lower mounting seat 4 have the same structure, the upper mounting seat 3 is also provided with a first mounting hole 40 arranged in an array along the center and circumference of the circle, and a second mounting hole 42 arranged in an array along the center and circumference of the circle of the upper mounting seat 3 on the periphery of the first mounting hole 40.

[0028] The vibration damping unit 2 is composed of 24 vibration damping rods 20 .

[0029] In this embodiment, the upper mounting seat 3 and the lower mounting seat 4 are both provided with 12 first mounting holes 40 and 12 second mounting holes 42, and the first mounting holes 40 on the lower mounting seat 4 and the upper mounting seat 3 correspond one to one, and the second mounting holes 42 on the lower mounting seat 4 and the upper mounting seat 3 correspond one to one.

[0030] Specifically, the 24 vibration-damping rods 20 are installed in the 12 first installation holes 40 and the 12 second installation holes 42 in a one-to-one correspondence.

[0031] In this embodiment, one end of the damping rod 20 is engaged with the first mounting hole 40 or the second mounting hole 42 on the lower mounting seat 4 , and the other end of the damping rod 20 is engaged with the corresponding first mounting hole 40 or the second mounting hole 42 on the upper mounting seat 3 .

[0032] Specifically, any one of the vibration damping rods 20 is clamped at one end with the first mounting hole 40 on the lower mounting seat 4 or the second mounting hole 42 on the lower mounting seat 4, and the other end is clamped with the first mounting hole 40 or the second mounting hole 42 on the upper mounting seat 3 that corresponds one to one with the first mounting hole 40 on the lower mounting seat 4 or the second mounting hole 42 on the lower mounting seat 4.

[0033] like Figure 3 As shown, in this embodiment, the damping rod 20 includes an upper rod 200 , a lower rod 201 and a damping spring 202 , and the upper rod 200 and the lower rod 201 are connected via the damping spring 202 .

[0034] Specifically, the upper rod 200 and the lower rod 201 are both cylindrical structures.

[0035] In this embodiment, the free ends of the lower rod 201 and the upper rod 200 are both provided with an integrally formed connecting ball 203. The connecting ball 203 is used to be clamped with the first mounting hole 40 or the second mounting hole 42 on the mounting seat 3 or the lower mounting seat 4.

[0036] Specifically, the connecting ball 203 is engaged in the first mounting hole 40 or the second mounting hole 42 in the upper mounting seat 3 or the lower mounting seat 4, and the connecting ball 203 can rotate in the first mounting hole 40 or the second mounting hole 42 engaged therewith.

[0037] like Figure 4 As shown, in this embodiment, the damping spring 202 is a double U-shaped structure, and both ends of the damping spring 202 are provided with mounting protrusions 204 for connecting with the upper rod 200 or the lower rod 201. The mounting protrusion 204 is a cylindrical structure.

[0038] Specifically, the damping spring 202 is a high manganese-based damping alloy U-shaped spring. The high manganese-based damping alloy material has a damping performance similar to that of rubber and a mechanical property similar to that of low carbon steel, thereby ensuring that the vibration reduction rod 20 has a higher stiffness and a better damping effect. In addition, the structure of the damping spring 202 can also be designed as a multi-U-shaped structure according to actual needs.

[0039] Specifically, one end of the upper rod 200 or the lower rod 201 away from the connecting ball 203 is connected to the mounting protrusion 204 by welding.

[0040] It can also be understood that an end of the upper rod 200 or the lower rod 201 away from the connecting ball 203 is provided with an external thread, and the mounting protrusion 204 is provided with an internal thread, and the two are fastened by the thread.

[0041] It can also be understood that an end of the upper rod 200 or the lower rod 201 away from the connecting ball 203 is provided with an internal thread, and the mounting protrusion 204 is provided with an external thread, and the two are fastened by the thread.

[0042] The working principle of the quick return shock absorber 1 provided in this embodiment is as follows: the quick return shock absorber 1 is connected to the main body of the equipment, such as a warship or a ship body, through the lower mounting seat 4, and the key equipment to be damped is provided on the upper mounting seat 3. The 24 damping rods 20 in the damping part 2 are respectively installed in the first mounting hole 40 and the second mounting hole 42 in the lower mounting seat 4 and the upper mounting seat 3, and the damping rods 20 installed in the first mounting hole 40 are tilted in the counterclockwise direction, while the damping rods 20 installed in the second mounting hole 42 are tilted in the clockwise direction. When the quick return shock absorber 1 is impacted by a strong external force, such a rehearsal method can ensure that the quick return shock absorber 1 has a symmetrical structure in the circumferential direction and a symmetrical load-bearing capacity, so that the key equipment to be damped will not have rotational displacement even when it is impacted by an external force, further improving the return time and return accuracy of the key equipment to be damped.

[0043] The beneficial effects of the quick return shock absorber provided in this embodiment are as follows: the quick return shock absorber provided by the present invention has a simple structure and is easy to maintain. A damping spring made of a high manganese-based damping alloy is used to design a shock absorber rod with high damping performance, and a combination of circumferentially mounted shock absorber rods is used to enable the quick return shock absorber to have high stiffness and high damping characteristics while being able to quickly return to its original position, thereby ensuring that the equipment can quickly and normally operate while obtaining a good shock absorption effect. Secondly, the present invention utilizes a damping spring for vibration reduction and resetting, so that the quick return shock absorber has a higher damping effect without the need for oil to achieve the damping effect. Compared with shock absorbers with traditional external dampers, the design is simplified and the cost is reduced.
