Detailed Description
For a better understanding of the objects, structures and functions of the present invention, a damping device for wall bushing according to the present invention will be described in further detail with reference to the accompanying drawings.
For convenience, a direction parallel to a reference surface such as the ground is referred to as "lateral", "horizontal", or the like, and a direction perpendicular to the "lateral" is referred to as "vertical", or the like.
As shown in fig. 1 and 2, one embodiment of the present invention provides a vibration damping device 100 for a wall bushing, including a connection mechanism 1 fixed opposite to a wall (not shown in the drawings), a vibration damping mechanism 2 fixed opposite to the connection mechanism 1 for damping a force from the wall, and a mounting mechanism 3 connected to the vibration damping mechanism 2, the mounting mechanism 3 being configured to receive the wall bushing 10 and form a fixed fit with the wall bushing 10.
In this arrangement, when the wall is subjected to external forces, the forces will be transmitted along the connection 1 and the damping 2 mechanisms to the mounting 3 and actuate the mounting 3 and wall bushing 10 on the mounting 3 to move together. In this process, the damping mechanism 2 will buffer the installation mechanism 3 and the wall bushing 10 during movement, so as to reliably protect the wall bushing 10 and further protect the line located in the wall bushing 10.
In one embodiment, as shown in fig. 3, the shock absorbing mechanism 2 includes a guide rod 21 provided on the connection mechanism 1 and forming a relatively fixed with the connection mechanism 1, and a movable portion 22 is provided on the guide rod 21, the movable portion 22 being configured to be movable in an axial direction of the guide rod 21. Meanwhile, buffer portions 23 are provided on both sides of the movable portion 22 on the guide bar 21. The buffer portion 23 is made of any material capable of being elastically deformed. In the present embodiment, the buffer portion 23 is provided as a coil spring provided in a set on the guide lever 21. However, the buffer portion 23 may be provided with elastic rubber provided in a set on the guide rod 21.
In this arrangement, when the movable portion 22 moves on the guide rod 21, the movable portion 22 can be brought into contact with the buffer portion 23, and the buffer portion 23 is compressed to be elastically deformed. Meanwhile, in the process of restoring the elastic deformation of the buffer portion 23, a force opposite to the moving direction of the movable portion 22 can be applied to the movable portion 22. In this way, the force from the movable portion 22 can be buffered.
Meanwhile, as shown in fig. 2, the mounting mechanism 3 is disposed at the free end of the movable portion 22 and is relatively fixed to the movable portion 22. In this arrangement, when a wall (not shown) is subjected to an externally input force, the force is transmitted along the connection mechanism 1 and the damper mechanism 2 to the mounting mechanism 3, and the mounting mechanism 3 and the wall bushing 10 on the mounting mechanism 3 are actuated to move together.
In the process, the movable portion 22 moves along the guide rod 21, and the movable portion 22 compresses the buffer portion 23 to be elastically deformed. At this time, the movable portion 22 receives a force opposite to the force from the wall body, which is applied by the buffer portion 23 recovering the elastic deformation. In this way, forces from the wall can be cushioned. This can reliably protect the wall bushing 10 and further protect the line located in the wall bushing 10.
In one embodiment, as shown in fig. 5, the movable portion 22 includes a slider 221 for connecting with the guide bar 21 and capable of moving along the axial direction of the guide bar 21, a fixing member 222 for fixing together with respect to the mounting mechanism 3, and a connecting member 223 disposed between the slider 221 and the fixing member 222 for connecting the slider 221 and the fixing member together. In this way, the movable part 22 and the mounting mechanism 3 can be relatively fixed together, and the movable part 22 moves to drive the mounting mechanism 3 to move synchronously.
Therein, as shown in fig. 5, a through hole 2211 is further provided on the slider 221, and the through hole 2211 is configured to be matched with the guide rod 21. In this way, the slider 221 can be inserted through the through hole 2211 on the guide rod 21. Thereby, the slider 221 is enabled to move along the path constituted by the guide bar 21.
Meanwhile, as shown in fig. 5, a groove 2221 is provided on the fixing piece 222. Also, as shown in fig. 6, a projection 31 is provided on the mounting mechanism 3, the projection 31 being configured to mate with the groove 2221. Further, the fixing member 222 is provided with a first mounting hole 2222, and the projection 31 is provided with a second mounting hole 311 corresponding to the first mounting hole 2222. In this way, the projection 31 can be disposed in the recess 2221, and the first mounting hole 2222 and the second mounting hole 311 can be made to correspond to each other. Meanwhile, a mounting pin (not shown) is inserted into the second mounting hole 311 along the first mounting hole 2222. Thereby, the fixing piece 222 can be relatively fixed with the mounting mechanism 3.
Further, as shown in fig. 6, the mounting mechanism 3 further includes a mounting portion 32 connected to the projection 31, and the mounting portion 32 is configured to receive the wall bushing 10 and is fixed together with respect to the wall bushing 10. In this embodiment, the mounting portion 32 includes a bottom plate 321, and an upwardly extending side plate 322 is provided on the bottom plate 321. Meanwhile, a top plate 323 is further provided on the side plate 322. In this way, the bottom plate 321, the side plates 322, and the top plate 323 together constitute a hollow rectangular structure.
Meanwhile, as shown in fig. 6, the mounting mechanism 3 further includes a mounting plate 324 provided on the outer side surface of the inner wall of the top plate 323 and extending to the inner side surface of the inner wall of the bottom plate 321. Specifically, the mounting plate 324 is disposed in the mounting portion 32 in an inclined manner, and forms a "Z" shape together with the bottom plate 321 and the top plate 323.
As shown in fig. 6, a fixing hole 325 is formed in the mounting plate 324, and the fixing hole 325 is configured to receive the wall bushing 10 and cooperate with the wall bushing 10. In this way, the wall bushing 10 can be fastened together in an inclined manner relative to the mounting means 3 for meeting the working requirements. It should be noted that, in actual operation, the wall bushing 10 is installed in an inclined manner.
In this arrangement, when it is desired to cushion forces laterally from the wall (not shown), the attachment mechanism 1 is laterally positioned on the wall and the guide bar 21 is laterally positioned on the attachment mechanism 1. Meanwhile, the movable portion 22 is inserted through the guide bar 21, and buffer portions 23 are respectively provided at both sides of the movable portion 22. Further, the mounting mechanism 3 is provided on the movable portion 22, and the projection 31 and the fixing piece 222 are made fixed relative to each other by a mounting pin (not shown in the figure). The wall bushing 10 is then connected to the mounting portion 32 and the wall bushing 10 and the mounting portion 32 are secured together.
In this process, when the wall is subjected to a lateral force, the force is transmitted to the mounting mechanism 3 along the connecting mechanism 1 and the damping mechanism 2, and the mounting mechanism 3 and the wall bushing 10 on the mounting mechanism 3 are actuated to move together. At this time, the movable portion 22 will move laterally along the path constituted by the guide bar 21. In this process, the movable portion 22 will contact with the buffer portion 23 located at the side of the movable portion 22, and compress the buffer portion 23 to elastically deform.
At the same time, the movable portion 22 will also receive a force opposite to the force from the wall body applied by the cushion portion 23 to resume the elastic deformation. In this way, forces from the wall can be cushioned. This can protect the wall bushing 10 and thus protect the line located in the wall bushing 10 in the lateral direction.
According to a preferred embodiment of the invention, the connecting means 1 are arranged in two parallel to each other. Meanwhile, the damper mechanism 2 and the projection 31 are provided in a corresponding manner to the connection mechanism 1. In this way, the mounting mechanism 3 is allowed to move only in the lateral direction, thereby improving the stability of the mounting mechanism 3. In this arrangement, the parallel damper mechanisms 2 can absorb the lateral force from the wall. This can further improve the damping performance of the present device 100.
However, when it is desired to cushion the force vertically from the wall (not shown), the connection mechanism 1 is vertically disposed on the wall, and the damper mechanism 2 is vertically disposed in a corresponding manner to the connection mechanism 1. At the same time, the movable portion 22 is connected to the mounting mechanism 3, and the wall bushing 10 is provided on the mounting mechanism 3.
In this arrangement, the damping portion 23 is capable of being elastically deformed in the vertical direction, thereby damping the vertical force from the wall. Thereby, the wall bushing 10 can be protected vertically, and further, the line located in the wall bushing 10 can be protected. The principle of damping the vertical force is the same as the principle of damping the horizontal force. Therefore, the description thereof is omitted. Preferably, the connecting mechanism 1 and the damping mechanism 2 may be arranged in parallel to each other to improve the damping performance in the vertical direction.
In one embodiment, as shown in fig. 3, the connection mechanism 1 is provided in at least two, and is relatively fixed to the wall body in a mutually perpendicular manner. Meanwhile, the shock absorbing mechanism 2 and the bump 31 are correspondingly arranged with the connecting mechanism 1. In this way, the mounting mechanism 3 can be connected to the damper mechanism 2 both in the lateral direction and in the vertical direction.
Wherein the connecting member 223 is made of any material capable of being elastically deformed. In this embodiment, the connecting member 223 is configured as at least one coil spring, and both ends of the coil spring are connected to the sliding member 221 and the fixing member 222, respectively.
In this arrangement, when the device 100 receives a force from a wall (not shown) in a lateral direction. The force will be continuously transmitted to the mounting means 3 and will actuate the mounting means 3 to move in the lateral direction. In this process, on the vibration absorbing mechanism 2 disposed laterally, the fixing member 222 is capable of transmitting the force to the movable member 221 along the connecting member 223, and making the movable member 221 move laterally along the guide rod 21, and compressing the buffer portion 23 after the movable member 221 and the buffer portion 23 abut against each other to elastically deform. Meanwhile, in the lateral direction, the movable member 221 is also subjected to the force of restoring the elastic deformation of the buffer portion 23. Thereby, the lateral force from the wall is buffered.
Furthermore, on the vertically arranged damper mechanism 2, the fixing member 222 will move synchronously with the mounting mechanism 3. In this process, the fixing member 222 elastically deforms the connecting member 223 provided between the fixing member 222 and the sliding member 221 in compression or extension. At the same time, the fixing member 222 is also subjected to the force of restoring the elastic deformation of the connecting member 223, thereby further buffering the vertical force from the wall.
However, when the present device 100 receives a force from the vertical direction of a wall (not shown), the force will actuate the mounting mechanism 3to move in the vertical direction. In this process, on the vertically arranged shock absorbing mechanism 2, the fixing member 222 is capable of transmitting the acting force to the movable member 221 along the connecting member 223, and making the movable member 221 vertically move along the guide rod 21, and compressing the buffer portion 23 to elastically deform after abutting against the buffer portion 23. Meanwhile, the movable member 221 is also subjected to a force of restoring the elastic deformation of the buffer portion 23 in the vertical direction. Thereby, the vertical forces from the wall are damped.
Further, on the transversely arranged damper mechanism 2, the fixing piece 222 will move synchronously with the mounting mechanism 3. In this process, the fixing member 222 elastically deforms the connecting member 223 provided between the fixing member 222 and the sliding member 221 in compression or extension. At the same time, the fixing member 222 will also receive the force of restoring the elastic deformation of the connecting member 223, so as to further buffer the vertical force from the wall. In this way, forces from both the lateral and vertical directions of the wall can be damped. This can improve the damping performance of the present device 100.
According to a preferred embodiment of the present invention, the connection member 223 is configured as four coil springs, such that the four coil springs are respectively disposed between the sliding member 221 and the fixing member 222 in a two-to-two opposite manner, and are respectively fixed to the sliding member 221 and the fixing member 222 in a relatively fixed manner. In this way, when the connection member 223 receives a force, the four coil springs can conduct the force. Thereby, the force can be transmitted more stably. In addition, any coil spring can conduct the acting force, and the stability of the device 100 can be improved.
According to a preferred embodiment of the present invention, as shown in fig. 3, the movable portions 22 are provided in two and respectively pass through the guide rods 21, and the protrusions 31 are provided to correspond to the movable portions 22. Meanwhile, the buffer parts 23 are arranged in three and are respectively positioned at two sides of the movable part 22. In this way, forces from the wall can be further damped.
In one embodiment, as shown in fig. 2, the device 100 further comprises a fixing frame 4, wherein the fixing frame 4 is configured to be fixed with a wall (not shown in the figure) and is used for receiving each connecting mechanism 1. In this arrangement, it is possible to facilitate the installation of several connection mechanisms 1. In addition, the parallel and vertical relationship between the plurality of connection mechanisms 1 can be ensured, so that the shock absorbing mechanism 2 connected with the connection mechanisms 1 can stably buffer the acting force from the wall body. In this embodiment, the fixing frame 4 is made of two pairs of connecting rods 41 parallel to each other. In this way, two pairs of connecting rods 41 parallel to each other are made to together constitute a rectangular structure for mounting the connecting mechanism 1.
Wherein, as shown in fig. 4, the connecting mechanism 1 comprises a first connecting part 11 arranged on the connecting rod 41 in a surrounding way, and a second connecting part 12 fixed together opposite to the first connecting part 11. Wherein, the second connecting part 12 is arranged in a hollow rectangular structure, and the rectangular cavity is internally provided with a damping mechanism 2. In this way, the damping mechanism 2 can be protected, so that interference between the damping mechanism 2 and external equipment is avoided, and the damping performance of the damping mechanism 2 is prevented from being affected.
Meanwhile, as shown in fig. 4, a first boss 111 is outwardly extended at the free end of the first connection part 11, and a second boss 121 is outwardly extended on the second connection part 12. The first boss 111 and the second boss 121 correspond to each other, and coupling holes (not shown) corresponding to each other, in which fixing bolts (not shown) can be selectively provided, are formed on the first boss 111 and the second boss 121. In this arrangement, the first connection portion 11 and the second connection portion 12 can be fixed relatively together in a selectable manner by the fixing bolt. Thereby, the connection mechanism 1 can be relatively fixed to the connection rod 41 in a selectable manner.
According to a preferred embodiment of the present invention, as shown in fig. 4, fixing heads 122 are respectively provided at both ends of the second connection part 12, and the guide bar 21 is provided in the second connection part 12 such that both ends of the guide bar 21 extend to the fixing heads 122 through the wall surface of the second connection part 12 and form a screw-fit with the fixing heads 122. In this way, the damper mechanism 2 can be detached from the connection assembly 1, thereby facilitating replacement of the damper mechanism 2.
The vibration damping device 100 for a wall bushing according to the present invention operates as follows.
First, the fixing frame 4 is disposed on a wall (not shown in the drawing), and the fixing frame 4 is relatively fixed to the wall. At the same time, four connection mechanisms 1 are provided, and four first connection portions 11 are provided on the respective connection bars 41, respectively. Also, the second connection portion 12 is provided on the opposite side of the first connection portion 11, and the first connection portion 11 and the second connection portion 12 are fixed to each other by fixing bolts (not shown in the drawing), so that the connection mechanism 1 is relatively fixed to the fixing frame 4.
Next, the movable portions 22 are provided in the respective second connection portions 12, and the buffer portions 23 are provided on both sides of the respective movable portions 22. Then, the guide rod 21 is inserted into the second connecting portion 12, and the movable portion 22 and the buffer portion 23 are both sleeved on the guide rod 21. At the same time, the guide rod 21 is screw-fitted with the fixing head 122 located on the second connecting portion 12.
Finally, the free ends of the movable portions 22 are connected to respective projections 31 provided on the mounting mechanism 3, and the movable portions 22 and the projections 31 are fixed to each other by mounting pins (not shown). Thus, the present apparatus 100 is assembled. At this time, the wall bushing 10 can be disposed on the mounting plate 324, and a relative fixation can be formed between the wall bushing 10 and the mounting plate 324.
When the present device 100 receives a force from a wall (not shown) in a lateral direction. The force will be continuously transmitted to the mounting means 3 and will actuate the mounting means 3 to move in the lateral direction. In this process, on the transversely arranged damper mechanism 2, the movable portion 22 will move transversely along the guide rod 21 and compress the buffer portion 23 to be elastically deformed. At the same time, the movable portion 22 is subjected to a force which is opposite to the movement direction of the movable portion 22 and is applied by the elastic deformation of the buffer portion 23. Thereby, the lateral force from the wall is buffered.
Furthermore, on the vertically arranged damper mechanism 2, the fixing member 222 will move synchronously with the mounting mechanism 3. In this process, the fixing member 222 compresses the connecting member 223 in the same direction as the movement direction of the mounting mechanism 3 to elastically deform, and stretches the connecting member 223 in the opposite direction to the movement direction of the mounting mechanism 3 to elastically deform. At this time, the fixing member 222 receives the force of restoring the elastic deformation of the connection member 223, thereby further buffering the lateral force from the wall.
However, when the present device 100 receives a force from the vertical direction of a wall (not shown), the force will drive the mounting mechanism 3 to move in the vertical direction. In the process, the vertically arranged damping mechanism 2 will damp the forces. In addition, during the vertical movement of the mounting mechanism 3, the connecting piece 223 arranged transversely is elastically deformed in compression and extension, and when the connecting piece 223 recovers the elastic deformation, the vertical acting force from the wall body is further buffered. In this way, forces from both the lateral and vertical directions of the wall can be damped. This can reliably protect the wall bushing 10 and further protect the line located in the wall bushing 10.
It will be understood that the application has been described in terms of several embodiments, and that various changes and equivalents may be made to these features and embodiments by those skilled in the art without departing from the spirit and scope of the application. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the application without departing from the essential scope thereof. Therefore, it is intended that the application not be limited to the particular embodiment disclosed, but that the application will include all embodiments falling within the scope of the appended claims.
