A cross roller type shock-absorbing structure for items

Abstract

This invention discloses a cross-shaped roller-type shock-absorbing structure for objects, relating to the field of equipment shock absorption technology. It includes mounting plates, characterized in that a plurality of shock-absorbing components are installed between two mounting plates. Each shock-absorbing component includes two track components, which are respectively mounted on the outer surfaces of the two mounting plates. The two track components are arranged in a cross shape, and a pulley assembly is provided between the two track components. This cross-shaped roller-type shock-absorbing structure discloses that by setting adjustable resistance elements, the more the resistance elements extend outward from the opening, the greater the resistance of the rollers, making it less likely for them to move to the extreme positions at both ends of the track plates. This prevents damage to the equipment from instantaneous vibration forces when it shifts to its extreme position during an earthquake.

Description

Technical Field

[0001] The present invention relates to the technical field of equipment shock absorption, and particularly to a cross roller type article shock absorption structure. Background Art

[0002] With the development of the economy and the improvement of people's living standards, more and more people begin to pay attention to the protection of high-value items. A variety of high-value items, such as precious cultural relics, data cabinets, high-value medical devices, important equipment, and test instruments, play an increasingly important role in people's production and life.

[0003] Common methods for reducing and isolating vibration of high-value items are to fix high-value items with columns, brackets, ropes, etc., so that they are not easily collapsed and damaged during vibration, but the effect is very limited. At present, except for some cultural relics using some vibration reduction and isolation devices, other items such as data cabinets, high-value medical devices, important equipment, and test instruments generally use shock-absorbing bases for vibration reduction and isolation. However, for some existing shock-absorbing bases, the shock-absorbing resistance is not easy to adjust. In the event of an earthquake, when the horizontal displacement of the house is large and the horizontal inertia of the instrument and equipment is large, it is easy to reach the movement limit point of the shock-absorbing base, and the instrument and equipment will still be damaged by the impact force. Summary of the Invention

[0004] The present invention discloses a cross roller type article shock absorption structure, aiming to solve the technical problem that the shock-absorbing resistance is not easy to adjust.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A cross roller type article shock absorption structure includes a mounting plate. A number of shock absorption components are installed between the two mounting plates. The shock absorption component includes two track components, and the two track components are respectively installed on the outer surfaces of the two mounting plates. The two track components are in a cross shape, and a pulley component is arranged between the two track components;

[0007] The track component includes a track plate, and the cross section of the track plate is "convex" shaped;

[0008] The pulley component includes a lower frame, and an upper frame is elastically connected to the outer wall of the lower frame. Rollers are rotatably arranged on the inner walls of the lower frame and the upper frame, and the rollers roll along the track plate;

[0009] Resistance members are movably arranged on the inner walls at both ends of the lower frame and the upper frame. The resistance members can move along the axial direction of the rollers. The closer the resistance member is to the central axis of the roller, the greater the resistance of the roller rolling along the track plate. And during the process that the roller moves to the limit position of the track plate, the resistance will continuously increase, but the roller will rotate normally;

[0010] When the resistance element moves away from the roller to its limit position along the central axis of the roller, the roller will be unable to rotate;

[0011] The resistance element prevents the roller from moving up and down.

[0012] In a preferred embodiment, the pulley assembly further includes a threaded rod threadedly connected to both ends of the lower frame and the upper frame. An adjusting plate is rotatably connected to the end of the threaded rod, and a rotating plate is rotatably connected to the outer surface of the adjusting plate. The resistance element is distributed around the outer surface of the rotating plate, and a plurality of through-holes are provided on the outer surface of the roller, with the resistance element located within the through-holes.

[0013] In a preferred embodiment, the resistance element includes a sleeve fixed to the outer surface of the rotating plate, and a tapered block is connected inside the sleeve via a return spring.

[0014] In a preferred embodiment, the track assembly further includes an arcuate portion disposed on the upper surface of the track plate.

[0015] In a preferred embodiment, the track assembly further includes arc-shaped slots on both sides of the track plate, and the resistance element extends outward from the opening and is located within the arc-shaped slot.

[0016] In a preferred embodiment, the track assembly further includes a first chamfered portion disposed at the edge of the curved surface, a second chamfered portion disposed at the upper edge of the curved groove, and stops disposed on the outer walls at both ends of the track plate.

[0017] In a preferred embodiment, the outer surface of the first chamfered portion is provided with grooves, the grooves are horizontally distributed, and the number of grooves increases outward from the lowest point of the curved surface.

[0018] In a preferred embodiment, the outer walls of the lower frame and the upper frame are provided with sliding grooves, the upper frame is slidably connected to the sliding grooves, and an elastic damping rod is provided inside the sliding grooves to provide a buffering effect.

[0019] In a preferred embodiment, the rotating plate has a toothed groove on the side near the threaded rod, and toothed blocks are correspondingly provided on the inner walls of both ends of the lower frame and the upper frame.

[0020] In a preferred embodiment, a rotating ring is provided on the side of the rotating plate near the threaded rod, and a rotating groove is correspondingly provided on one side of the adjusting plate.

[0021] As can be seen from the above, the cross-shaped roller shock absorption structure provided by the present invention has the following technical effects.

[0022] Firstly, by rotating the threaded rod in the forward direction, the resistance component can extend outward from the opening. As the roller rotates, the resistance component will contact the edge of the track plate. At the same time, the conical block of the resistance component will be forced to contract inward through the return spring. In this way, resistance is applied to the rolling of the roller. The more the resistance component extends outward from the opening, the greater the resistance of the roller, and the less likely it is to move to the extreme positions at both ends of the track plate. This avoids damage to the equipment due to instantaneous vibration when it is displaced to the extreme position during an earthquake.

[0023] Secondly, since earthquakes not only cause horizontal displacement but also a small amount of vertical displacement, the resistance components located in the arc-shaped groove can provide vertical restraint force to the rollers to prevent them from detaching from the track plate, thus preventing the rollers from detaching to a certain extent.

[0024] Thirdly, the grooves provide resistance to the retraction of the conical block. The closer the grooves are to the stop, the more grooves there are, which makes the resistance of the roller approaching the stop greater. In this way, the impact force when the roller contacts the stop can be buffered, avoiding damage to the equipment caused by large vibration forces. Attached Figure Description

Detailed Implementation

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0039] Reference Figures 1-10, A cross - roller type shock - absorbing structure for articles, including a mounting plate 1. Between the two mounting plates 1, several shock - absorbing components 2 are installed. The shock - absorbing component 2 includes two track components 3. The two track components 3 are respectively installed on the outer surfaces of the two mounting plates 1. The two track components 3 are in a cross - shaped pattern, and a pulley component 4 is arranged between the two track components 3. The track component 3 includes a track plate 301, and the cross - section of the track plate 301 is in a "convex" shape. The pulley component 4 includes a lower frame 401. An upper frame 402 is elastically connected to the outer wall of the lower frame 401. Rollers 404 are rotatably arranged on the inner walls of the lower frame 401 and the upper frame 402. The rollers 404 roll along the track plate 301. Resistance members 408 are movably arranged on the inner walls at both ends of the lower frame 401 and the upper frame 402. The resistance members 408 can move along the axis direction of the rollers 404. The closer the resistance members 408 are to the central axis of the rollers 404, the greater the resistance for the rollers 404 to roll along the track plate 301, but the rollers 404 can still rotate normally. When the resistance members 408 move away from the central axis of the rollers 404 to the extreme position, the rollers 404 will not be able to rotate. The resistance members 408 can prevent the rollers 404 from moving up and down.

[0040] In this embodiment, when the required equipment needs shock - absorption, the equipment can be placed on the mounting plate 1 for fixation. The shock - absorbing component 2 at the bottom of the mounting plate 1 is composed of two oppositely arranged track plates 301. The two track plates 301 are distributed in a cross - shape, and the two groups of rollers 404 arranged in the middle can respectively roll along the track plates 301, ensuring that during the process of the equipment being subjected to horizontal vibration force, the rollers 404 can move along the X - axis and Y - axis directions, thereby consuming the horizontal shear force generated by the earthquake.

[0041] When the equipment to be shock - absorbed is heavy, due to inertia, the equipment will more easily move to the extreme positions at both ends of the track plate 301, thus being subjected to a strong instantaneous vibration force. In order to design different shock - absorption effects for equipment of different weights, the position of the resistance members 408 can be changed to increase the resistance of the rollers 404, so that it is not easy for them to approach the extreme positions of the track plate 301.

[0042] Specifically, referring to Figures 4-7 , the pulley component 4 further includes a threaded rod 405. The threaded rod 405 is threadedly connected to both ends of the lower frame 401 and the upper frame 402. The end of the threaded rod 405 is rotatably connected to an adjusting plate 406. A rotating piece 407 is rotatably connected to the outer surface of the adjusting plate 406. The resistance members 408 are distributed around the outer surface of the rotating piece 407. A number of through - holes 409 are formed through the outer surface of the rollers 404. The resistance members 408 are located in the through - holes 409. The resistance member 408 includes a sleeve 4081 fixed to the outer surface of the rotating piece 407. A conical block 4083 is connected to the inside of the sleeve 4081 through a return spring 4082.

[0043] In this embodiment, the adjusting plate 406 at the end of the threaded rod 405 can be rotated to move closer to the roller 404. At the same time, the rotating plate 407 and the resistance member 408 on its outer surface will also move together. Once the resistance member 408 extends outward from the opening 409, as the roller 404 rotates, the resistance member 408 will contact the edge of the track plate 301. At the same time, the cone block 4083 of the resistance member 408 will be forced to contract inward through the return spring 4082. In this way, resistance is applied to the rolling of the roller 404. The more the resistance member 408 extends outward from the opening 409, the greater the resistance of the roller 404, and the less likely it is to move to the extreme positions at both ends of the track plate 301.

[0044] It is worth noting that the weight and inertia of the equipment itself can easily drive the roller 404 to roll along the track plate 301, thereby consuming the horizontal shear force. This prevents the equipment from easily moving to the horizontal limit point. In addition, the rotation of the threaded rod 405 has a certain resistance to prevent the vibration force from causing the threaded rod to rotate.

[0045] Specifically, refer to Figure 3 The track assembly 3 also includes an arc-shaped surface 302 disposed on the upper surface of the track plate 301. When the earthquake stops, due to the influence of the equipment's own gravity, the roller 404 can roll along the arc-shaped surface 302, thereby restoring stability. In addition, the resistance provided by the resistance component 408 to the roller 404 enables the equipment to reach a stable state more quickly.

[0046] Furthermore, refer to Figure 3 and Figure 4 The track assembly 3 also includes arc-shaped slots 303 on both sides of the track plate 301. The resistance element 408 extends outward from the opening 409 and is located in the arc-shaped slot 303. When an earthquake occurs, not only will there be horizontal displacement, but there will also be a small amount of vertical displacement. In order to prevent the roller 404 from detaching from the track plate 301, the resistance element 408 located in the arc-shaped slot 303 can provide a vertical limiting force for the roller 404, thus preventing the roller 404 from detaching to a certain extent.

[0047] Furthermore, the track assembly 3 also includes a first chamfered portion 304 disposed on the edge of the curved surface 302, a second chamfered portion 305 disposed on the upper edge of the curved groove 303, and stops 307 disposed on the outer walls of both ends of the track plate 301. During the rotation of the roller 404, the conical block 4083 of the resistance member 408 will first contact the first chamfered portion 304, thereby facilitating the conical block 4083 to retract inward. When the conical block 4083 rotates to the curved groove 303, it will pop outward. Then, when the conical block 4083 rotates to the second chamfered portion 305, it will continue to retract inward. This process is repeated. The stops 307 are used to prevent the roller 404 from detaching from the track plate 301. The position of the stops 307 is the limit point of the horizontal shock absorption movement.

[0048] When adjusting the position of the resistance member 408, the smaller the contact area between the conical block 4083 and the first chamfered portion 304, the smaller the retraction process of the conical block 4083, and the smaller the resistance provided by the resistance member 408 to the roller 404, and vice versa.

[0049] Furthermore, such as Figure 4 and Figure 11 As shown, the outer surface of the first chamfered portion 304 is provided with grooves 306. The grooves 306 are horizontally distributed, and the number of grooves 306 increases outward from the lowest point of the arc portion 302. The grooves 306 provide resistance to the retraction of the conical block 4083. The closer the grooves 306 are to the stop block 307, the more grooves there are, which makes the resistance of the roller 404 approaching the stop block 307 greater. In this way, the impact force when the roller 404 contacts the stop block 307 can be buffered, avoiding damage to the equipment caused by large vibration forces.

[0050] Specifically, the lower frame 401 and the upper frame 402 are provided with sliding grooves 403 on their outer walls. The upper frame 402 is slidably connected to the sliding grooves 403. An elastic damping rod is provided inside the sliding grooves 403 to provide a buffering effect. During an earthquake, the lower frame 401 and the upper frame 402 can undergo a small vertical displacement, thereby consuming some of the vertical vibration force and preventing the rollers 404 from detaching from the track slab 301 to a certain extent.

[0051] Furthermore, such as Figure 6 As shown, the rotating plate 407 has a toothed groove 410 on the side near the threaded rod 405. The inner walls of both ends of the lower frame 401 and the upper frame 402 are respectively provided with toothed blocks 411. By rotating the threaded rod 405 in the opposite direction, the adjusting plate 406 and the rotating plate 407 can be moved towards the toothed blocks 411, so that the toothed blocks 411 mesh with the toothed groove 410, preventing the rotating plate 407 and the roller 404 from rotating. In this state, the shock absorption effect of the equipment is the lowest, the equipment stability is the highest, and it is convenient for personnel to carry out maintenance and other work on the equipment, avoiding personnel touching the equipment and causing it to shake.

[0052] Furthermore, such as Figure 8 and Figure 9 As shown, a rotating ring 412 is provided on the side of the rotating plate 407 near the threaded rod 405, and a rotating groove 413 is correspondingly provided on one side of the adjusting plate 406. During the rotation of the roller 404, the roller 404, the resistance element 408 and the rotating plate 407 will rotate along the rotating groove 413 through the rotating ring 412.

[0053] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made to the technical solutions and inventive concepts of the present invention should all be covered within the scope of protection of the present invention.
