Abstract
Description
Technical Field
[0001] This utility model belongs to the field of disc spring bracket technology, and in particular relates to a rubber disc spring bracket. Background Technology
[0002] A rubber disc spring bracket is a mechanical support component that combines the elasticity of rubber with the load-bearing characteristics of a disc spring. It can provide stable support force within a certain range, while also possessing good shock absorption and buffering performance. It is widely used in various applications that require bearing axial loads and reducing vibration transmission. However, existing rubber disc springs are difficult to adjust the preload according to the actual load they bear, making it difficult to accurately adapt to various conditions from light to heavy loads. Therefore, when the equipment is under no-load or light-load conditions, the disc spring may be over-compressed, resulting in energy waste or premature failure. Under heavy loads, it is difficult to enhance the support force through appropriate adjustment to ensure stable operation of the equipment, thereby reducing the equipment's support force and significantly reducing its service life. To address this issue, a rubber disc spring bracket is proposed. Utility Model Content
[0003] The purpose of this invention is to provide a rubber disc spring bracket. By setting an adjustment component, specifically, rotating a knob clockwise drives a threaded rod to move a guide sleeve downwards. During this downward movement, the guide sleeve causes the upper tray to compress the rubber disc spring body, thereby adjusting the preload of the rubber disc spring body. This allows it to accurately adapt to various conditions from light to heavy loads. This solves the problem that existing rubber disc springs cannot adjust their preload according to the actual load they can bear, making it difficult to accurately adapt to various conditions from light to heavy loads. Therefore, when the equipment is unloaded or lightly loaded, the disc spring may be over-compressed, resulting in energy waste or premature failure. Under heavy loads, it is difficult to appropriately adjust and increase the support force to ensure stable operation of the equipment, thus reducing the equipment's support force and significantly shortening its service life.
[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0005] This utility model relates to a rubber disc spring bracket, comprising a support cylinder, a support base welded to the bottom of the support cylinder, an installation platform disposed above the support cylinder, a rubber disc spring body disposed inside the support cylinder, and further comprising:
[0006] An adjustment unit is installed at the bottom of the mounting platform and is used to adjust the preload of the rubber disc spring body.
[0007] A pushing part is installed inside the support cylinder, and the pushing part is driven by an adjusting part to compress the rubber disc spring body;
[0008] The support cylinder is made of metal, while the rubber disc spring body is made of rubber. The adjustment mechanism enhances the support effect of the device.
[0009] Furthermore, the adjustment unit includes an adjustment assembly, which is rotatably connected to the mounting platform and provides power output for compressing the rubber disc spring body;
[0010] A limiting component is installed inside the support cylinder, and the limiting component provides a certain degree of limitation on the movement trajectory of the rubber disc spring body;
[0011] In particular, the movement trajectory of the rubber disc spring body is limited by the limiting component, which improves the vertical movement effect of the rubber disc spring body and thus extends the service life of the equipment.
[0012] Furthermore, the pushing part includes a squeezing assembly, which is installed inside the support cylinder. During the movement of the squeezing assembly, the rubber disc spring body is squeezed.
[0013] The movement trajectory of the extrusion component is also limited by the limiting component.
[0014] Furthermore, the adjustment assembly includes a threaded rod that passes through the mounting platform and extends to the top. Limiting rings are provided at both the top and bottom of the mounting platform. The inner rings of the two limiting rings are welded to the outer surface of the threaded rod. A knob is provided at the bottom of the limiting ring located at the bottom. The inner ring of the knob is welded to the outer surface of the threaded rod.
[0015] The threaded rod has one end away from the mounting platform that passes through the support cylinder and extends into the interior.
[0016] Furthermore, the limiting component includes a guide tube, the bottom of which is welded to the bottom of the inner wall of the support cylinder, and a plurality of sliding grooves are formed on the outer surface of the guide tube, with sliding strips slidably connected inside each of the plurality of sliding grooves;
[0017] The guide tube is hollow inside, and the outer surface of the threaded rod is in contact with the inner wall of the guide tube.
[0018] Furthermore, the extrusion assembly includes a guide sleeve, the top of which is threaded to the outer surface of the threaded rod. The guide sleeve passes through the support cylinder and extends into it. An upper tray is provided inside the support cylinder. The inner ring of the upper tray is welded to the outer surface of the guide sleeve. The bottom of the upper tray contacts the rubber disc spring body located at the top. A lower tray is welded to the bottom of the inner wall of the support cylinder. The top of the lower tray contacts the rubber disc spring body located at the bottom.
[0019] The inner wall of the guide sleeve is welded to one side of several sliding bars that are far apart from each other.
[0020] This utility model has the following beneficial effects:
[0021] 1. This utility model incorporates an adjustment component. Specifically, rotating the knob clockwise causes the threaded rod to move the guide sleeve downwards. During this downward movement, the upper tray compresses the rubber disc spring body, thereby adjusting the preload of the rubber disc spring body. This allows it to precisely adapt to various conditions, from light to heavy loads. When the equipment is unloaded or lightly loaded, it prevents the disc spring from wasting energy or failing prematurely due to excessive compression. Under heavy loads, appropriate adjustments can enhance the support force, ensuring stable operation of the equipment. This not only improves the equipment's support force but also significantly extends its service life.
[0022] 2. This utility model, by setting a limiting component, specifically, when the installation platform moves downward under force, several sliding bars will slide inside the sliding groove, providing a certain stability for the vertical movement of the guide sleeve. At the same time, when the guide sleeve squeezes the rubber disc spring body through the upper tray, several rubber disc spring bodies will slide on the outer surface of the guide tube. The guide tube limits the movement trajectory of the rubber disc spring body, improving the vertical contraction effect of the rubber disc spring body, greatly enhancing the guiding effect of the equipment on the rubber disc spring body, and further improving the support effect of the equipment.
[0023] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Please see Figures 1-5 As shown, this utility model is a rubber disc spring bracket, including a support cylinder 111, a support base 112 welded to the bottom of the support cylinder 111, an installation platform 113 provided above the support cylinder 111, a rubber disc spring body 114 provided inside the support cylinder 111, and further including:
[0034] Adjustment part 2 is installed at the bottom of the mounting platform 113 and is used to adjust the preload of the rubber disc spring body 114;
[0035] The pusher 3 is installed inside the support cylinder 111. The pusher 3 is driven by the adjustment unit 2 to compress the rubber disc spring body 114.
[0036] The support cylinder 111 is made of metal, while the rubber disc spring body 114 is made of rubber. The adjustment part 2 is used to improve the support effect of the equipment.
[0037] Adjustment unit 2 includes adjustment component 21, which is rotatably connected to mounting platform 113 and provides power output to compress rubber disc spring body 114;
[0038] Limiting component 22 is installed inside the support cylinder 111. Limiting component 22 provides a certain degree of limitation on the movement trajectory of the rubber disc spring body 114.
[0039] The movement trajectory of the rubber disc spring body 114 is limited by the limiting component 22, which improves the vertical movement effect of the rubber disc spring body 114 and thus extends the service life of the equipment.
[0040] The pushing part 3 includes a squeezing assembly 31, which is installed inside the support cylinder 111. During the movement of the squeezing assembly 31, it squeezes the rubber disc spring body 114.
[0041] The movement trajectory of the extrusion component 31 is also limited by the limiting effect of the limiting component 22.
[0042] The adjustment assembly 21 includes a threaded rod 211 that passes through the mounting platform 113 and extends to the top. Limiting rings 212 are provided at the top and bottom of the mounting platform 113. The inner rings of the two limiting rings 212 are welded to the outer surface of the threaded rod 211. A knob 213 is provided at the bottom of the limiting ring 212 located at the bottom. The inner ring of the knob 213 is welded to the outer surface of the threaded rod 211.
[0043] The threaded rod 211, with one end away from the mounting platform 113, passes through the support cylinder 111 and extends into the interior. Rotating the knob 213 clockwise causes the guide sleeve 311 to move downwards via the threaded rod 211. During the downward movement of the guide sleeve 311, the upper tray 312 compresses the rubber disc spring body 114, thereby adjusting the preload of the rubber disc spring body 114. This allows it to accurately adapt to various conditions from light load to heavy load. When the equipment is in an unloaded or light load state, it can prevent the disc spring from wasting energy or failing prematurely due to excessive compression. Under heavy load, it can enhance the support force through appropriate adjustment, ensuring stable operation of the equipment. While improving the support force of the equipment, it also significantly extends the service life of the equipment.
[0044] The limiting component 22 includes a guide tube 221. The bottom of the guide tube 221 is welded to the bottom of the inner wall of the support cylinder 111. Several grooves 222 are opened on the outer surface of the guide tube 221. Sliding strips 223 are slidably connected inside the grooves 222.
[0045] The guide tube 221 is hollow inside, and the outer surface of the threaded rod 211 contacts the inner wall of the guide tube 221. When the mounting platform 113 moves downward under force, several slide bars 223 will slide inside the slide groove 222, providing a certain stability for the vertical movement of the guide sleeve 311. At the same time, when the guide sleeve 311 squeezes the rubber disc spring body 114 through the upper tray 312, several rubber disc spring bodies 114 will slide on the outer surface of the guide tube 221. The guide tube 221 limits the movement trajectory of the rubber disc spring bodies 114, improves the vertical contraction effect of the rubber disc spring bodies 114, greatly improves the guiding effect of the equipment on the rubber disc spring bodies 114, and further improves the support effect of the equipment.
[0046] The extrusion assembly 31 includes a guide sleeve 311. The top of the inside of the guide sleeve 311 is threadedly connected to the outer surface of the threaded rod 211. The guide sleeve 311 passes through the support cylinder 111 and extends into it. An upper tray 312 is provided inside the support cylinder 111. The inner ring of the upper tray 312 is welded to the outer surface of the guide sleeve 311. The bottom of the upper tray 312 contacts the rubber disc spring body 114 located at the top. A lower tray 313 is welded to the bottom of the inner wall of the support cylinder 111. The top of the lower tray 313 contacts the rubber disc spring body 114 located at the bottom.
[0047] The inner wall of the guide sleeve 311 is welded to the side of several slide bars 223 that are far apart from each other.
[0048] A specific application of this embodiment is as follows: In use, the operator first fixes the installation platform 113 to the load object, and then connects the support base 112 to the support object. Then, the operator adjusts the preload of the rubber disc spring body 114 according to the actual load. Specifically, the operator rotates the knob 213 clockwise to rotate the threaded rod 211. When the threaded rod 211 rotates, it drives the guide sleeve 311 to move downwards. As the guide sleeve 311 moves, it drives several sliding strips 223 to slide inside the groove 222. At this time, the sliding strips 223, through the action of the groove 222, guide the movement trajectory of the guide sleeve 311. The guide sleeve 311 slides inside the support cylinder 111 during its movement. As the guide sleeve 311 moves downward, it drives the upper tray 312 to move together. During the movement of the upper tray 312, it compresses the rubber disc spring body 114, thereby adjusting the preload of the rubber disc spring body 114. This allows it to accurately adapt to various conditions from light load to heavy load. When the equipment is in an unloaded or light load state, it can prevent the disc spring from wasting energy or failing prematurely due to excessive compression. Under heavy load, it can enhance the support force through appropriate adjustment, ensuring stable operation of the equipment. While improving the support force of the equipment, it also greatly extends the service life of the equipment.
[0049] During equipment use, when the mounting platform 113 moves downward under force, the mounting platform 113 will drive the threaded rod 211 to move downward through the action of the two limit rings 212. At the same time, the threaded rod 211 will drive the guide sleeve 311 to move together through the principle of thread self-locking. At this time, several slide bars 223 will also slide inside the slide groove 222, providing a certain stability for the vertical movement of the guide sleeve 311. Meanwhile, when the guide sleeve 311 squeezes the rubber disc spring body 114 through the upper tray 312, several rubber disc spring bodies 114 will slide on the outer surface of the guide tube 221. The guide tube 221 limits the movement trajectory of the rubber disc spring bodies 114, improves the vertical contraction effect of the rubber disc spring bodies 114, greatly improves the guiding effect of the equipment on the rubber disc spring bodies 114, and further improves the support effect of the equipment.
