Description

Technical Field

[0001] This utility model relates to the field of vibration reduction technology, and more specifically, to a high-stability vibration reduction bracket. Background Technology

[0002] Many devices in our daily lives and work often generate a lot of noise due to vibration during operation, such as common motors, polishing machines, cooling towers, etc. The vibration noise of these devices has a great impact on people's work and life. Therefore, when installing such equipment, we usually use vibration dampers to reduce vibration.

[0003] Most existing elevator cars slide along guide rails using guide shoes mounted on both sides. When the elevator is running, vibrations generated by friction between the guide shoes and the guide rails, as well as other forms of vibration, are transmitted to the car via the traction ropes, affecting passenger comfort. Simultaneously, these vibrations are also transmitted to the building's internal structure through the rigid connection between the elevator guide rails and the building structure, creating low-frequency vibration noise that disrupts residents' daily lives. Therefore, vibration damping devices are needed to reduce noise.

[0004] Chinese invention patent application CN118597933A discloses an elevator guide rail vibration damping bracket. The bracket is fixedly connected to the main housing via a first connecting component and to the guide rail connection via a second connecting component. A non-contact gap exists between the first and second connecting components, making them relatively independent. This, in turn, makes the main housing and guide rail connection relatively independent, preventing noise generated by rigid collisions between the first and second connecting components and between the main housing and guide rail connection due to elevator vibrations. However, because the vibration damping components on this bracket are not pre-loaded and locked during installation, the overall stability of the vibration damping system is low. Furthermore, since the system uses only a single rubber block, which can only maintain its original thickness, there is a risk of large deformation leading to vibration damping failure. Utility Model Content

[0005] The main objective of this invention is to propose a highly stable vibration damping bracket to solve the technical problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model proposes a high-stability vibration damping bracket, comprising:

[0007] A first housing having an installation chamber;

[0008] The second housing is located on one side of the mounting chamber port of the first housing, and the first housing and the second housing can be close to or far from each other;

[0009] The vibration damping section is disposed between the first housing and the second housing;

[0010] The vibration damping component also includes a connecting portion for connecting the first housing and the second housing, such that both ends of the vibration damping component abut against the first housing and the second housing respectively; wherein the vibration damping bracket further includes:

[0011] The pre-compression locking part is located between the housing and the connecting parts and is used to pre-compress and lock the vibration damping part.

[0012] In the above technical solution, the connecting part further includes:

[0013] The first connector has a first mounting groove formed by bending in its middle part, and both ends of the first connector are disposed on the first housing.

[0014] The second connector has a second mounting groove formed by bending in its middle part. Both ends of the second connector are disposed on the second housing. The second connector and the first connector are arranged crosswise, so that the second mounting groove is opposite to the first mounting groove.

[0015] The vibration damping part is disposed in the cavity formed by the first mounting groove and the second mounting groove.

[0016] In any of the above technical solutions, the pre-pressure locking part further includes:

[0017] A clamping member, one end of which is disposed at the end of the first connecting member and the other end of which is disposed on the connecting component, is used to adjust the height of the cavity formed between the first mounting groove and the second mounting groove, so as to adjust the preload pressure of the vibration damping part.

[0018] In any of the above technical solutions, the pre-pressure locking part further includes:

[0019] A connecting plate is located at the side end of the second housing;

[0020] And the clamping block, which is made of elastic material;

[0021] One end of the clamping member is set on the connecting plate, and the other end passes through the connecting plate and is connected to the clamping block, so that the clamping block abuts against the end of the first connecting member.

[0022] In any of the above technical solutions, the clamping block is further made of rubber material.

[0023] In any of the above technical solutions, the vibration damping part is further made of a rubber block made of rubber material.

[0024] In any of the above technical solutions, the pre-pressure locking part has two sets, which are respectively disposed on both sides between the first connector and the second connector.

[0025] Beneficial effects: Compared with existing technologies, the pre-compression locking part is used to pre-tighten the vibration damping part. After the vibration damping part is installed, it can be pre-tightened by adjusting the pre-compression locking part according to actual needs. At the same time, the maximum deformation of the vibration damping part is reduced after pre-tightening, thereby reducing the occurrence of failure accidents caused by large deformation of the vibration damping part. Moreover, after pre-tightening, the entire vibration damping bracket structure is more compact and less prone to loosening. Attached Figure Description

[0039] The following embodiments will be used to provide a detailed description of a high-stability vibration damping bracket of this application.

[0040] Example 1:

[0041] As shown in the figure, in this embodiment, a high-stability vibration damping bracket includes: a first housing 1 having an installation chamber; a second housing 2 located on one side of the installation chamber port of the first housing 1, and the first housing 1 and the second housing 2 can be close to or far from each other; a vibration damping part 3 disposed between the first housing 1 and the second housing 2; and a connecting part 4 for connecting the first housing 1 and the second housing 2, such that both ends of the vibration damping part 3 abut against the first housing 1 and the second housing 2 respectively.

[0042] The vibration damping bracket also includes a pre-compression locking part 5, which is located between the housing and the connecting part 4, and is used to pre-compress and lock the vibration damping part 3.

[0043] The first housing 1 and the second housing 2 are respectively connected to the fixed object and the equipment requiring vibration damping. After the equipment vibrates during operation, the vibration damping unit 3 can absorb the vibration, thereby reducing the vibration amplitude and noise of the equipment. However, since the vibration damping unit 3 was not pre-tightened during installation, it is prone to loosening and damage due to its large deformation, which greatly reduces the vibration damping effect of the entire vibration damping system or causes it to fail.

[0044] Therefore, this embodiment includes a pre-compression locking part 5 to achieve the purpose of pre-tightening the vibration damping part 3. After the vibration damping part 3 is installed, the pre-compression locking part 5 is adjusted according to actual needs to pre-tighten the vibration damping part 3. At the same time, the maximum deformation of the vibration damping part 3 is reduced after pre-tightening, thereby reducing the occurrence of failure accidents caused by large deformation of the vibration damping part 3. Moreover, after pre-tightening, the structure of the entire vibration damping bracket is more compact and less prone to loosening.

[0045] It should be noted that, for ease of processing and installation, the first housing 1 and the second housing 2 are sheet metal structures. Specifically, a square plate is stamped to form a square groove structure, and then mounting plates are stamped on both sides to form the first housing 1. The second housing 2 is stamped from a long strip of plate.

[0046] It should be noted that the vibration damping part 3 is a rubber block made of rubber material.

[0047] In this embodiment, the connecting part 4 includes: a first connecting member 41, the middle part of which has a first mounting groove formed by bending, and the two ends of the first connecting member 41 are disposed on the first housing 1; a second connecting member 42, the middle part of which has a second mounting groove formed by bending, and the two ends of the second connecting member 42 are disposed on the second housing 2. The second connecting member 42 and the first connecting member 41 are arranged crosswise, so that the second mounting groove is opposite to the first mounting groove.

[0048] The vibration damping part 3 is disposed in the cavity formed by the first mounting groove and the second mounting groove.

[0049] It should be noted that the first connector 41 and the second connector 42 are also sheet metal parts. By stamping the middle part of the two long strips of plates to form a concave shape, the bent plates can be installed in a cross shape. During this process, the vibration damping part 3 is first installed between the two, and then they are fixed to the first housing 1 and the second housing 2 respectively.

[0050] In this embodiment, the pre-pressure locking part 5 includes a pressing member 51, one end of which is disposed at the end of the first connecting member 41 and the other end is disposed on the second housing 2, for adjusting the height of the cavity formed by the first mounting groove and the second mounting groove, so as to adjust the pre-tightening pressure of the vibration damping part 3.

[0051] Specifically, the pre-pressure locking part 5 includes a clamping member 51, one end of which is disposed at the end of the first connecting member 41 and the other end is disposed on the connecting part 4, for adjusting the height of the cavity formed between the first mounting groove and the second mounting groove, so as to adjust the pre-tightening pressure of the vibration damping part 3.

[0052] In this embodiment, the optimized pre-pressurization locking part 5 further includes: a connecting plate disposed at the side end of the second housing 2; and a pressing block 53 made of elastic material;

[0053] One end of the clamping member 51 is disposed on the connecting plate, and the other end passes through the connecting plate and is connected to the clamping block 53, so that the clamping block 53 abuts against the end of the first connecting member 41.

[0054] By setting the connecting plate, one end of the clamping member 51 is located on the outside, facilitating adjustment and installation. Specifically, the connecting plate consists of a first plate 521 and a second plate 522. The first plate 521 is mounted on the second housing 2, with both ends extending from the second housing 2. The second plate 522 is mounted on one of the extended ends of the first plate 521. The clamping member 51 is threadedly connected to the second plate 522, and after passing through the second plate 522, it is connected to the clamping block 53. By rotating the clamping member 51, it gradually moves inward, and its other end gradually applies pressure to the clamping block 53, causing the clamping block 53 to be squeezed. This squeezing will subject the first connecting member 41 to compressive force, causing the first connecting member 41 to move closer to the second connecting member 42, thereby squeezing the vibration damping part 3.

[0055] It should be noted that the clamping block 53 is a rubber block made of rubber material.

[0056] It should be noted that the pre-pressure locking part 5 has two sets, which are respectively arranged on both sides between the first connector 41 and the second connector 42 to provide a stable pre-tightening force for the vibration damping part 3.

[0057] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
