The damping pad 2 in this embodiment is made of rubber, and may be made of an elastic polymer material such as polyurethane. In addition, be provided with three locating part in this embodiment, and three locating part is triangle-shaped and sets up, and three locating part cooperatees like this and can guarantee the locking effect to casing 1. It should be noted that the first housing 10 and the second housing 11 in this embodiment refer to two divided parts of the housing 1 for facilitating the installation of the damping pad 2, and the first substrate 100 in this embodiment is provided with a limiting member, and in essence, refers to one of the two divided parts of the housing 1 provided with a limiting member is named as the first housing 10, and the other one is named as the second housing 11 provided with a fastening member.

In this embodiment, the limiting member is disposed on the first substrate 100, the fastener is disposed on the second substrate 110, the first housing 10 and the second housing 11 are locked by the fastener and the limiting member through threaded connection, the damping pad 2 is compressed and clamped tightly by the first substrate 100 and the second substrate 110 in a state that the first housing 10 and the second housing 11 are locked, the damping pad 2 is compressed and compressed in advance to increase the rigidity, and the elevator guide rail 9 is not shifted due to excessive deformation when vibration occurs, so that the influence on the running balance of the car can be avoided, and potential safety hazards are avoided. In addition, the inventor finds that the damping performance of the damping pad 2 is improved after the damping pad is compressed, specifically, the damping performance is better when the compressed amount of the damping pad 2 is larger in a certain range, and after the range is exceeded, the damping pad 2 has larger rigidity and poorer elastic deformation capability, and the damping performance of the damping pad 2 is poor at the moment. Therefore, after the damping pad 2 is compressed and clamped, it is necessary to control the degree of compression of the damping pad 2 to avoid excessive compression. It is difficult to accurately achieve the desired degree of compression if determined empirically by the operator at the time of assembly. To solve the problem, the limiting member in this embodiment cooperates with the fastening member to lock the first housing 10 and the second housing 11, and on the other hand, the limiting member can also limit the distance between the first substrate 100 and the second substrate 110, so that the damping pad 2 can be prevented from being compressed excessively during the process of locking the housing 1 and compressing the damping pad 2, thereby ensuring that the damping pad 2 is compressed to a required degree and has good damping performance. That is, the length of the limiting member can be designed and manufactured according to the compressed thickness value of the damping pad 2, so that the compressed thickness of the damping pad 2 is controlled in the assembling process through the length of the limiting member, and the damping effect is ensured to be good.

Specifically, in the present embodiment, the limiting member uses a nut post 4, the fastening member uses a first screw 5 adapted to the nut post, that is, the first screw 5 is screwed into the nut post 4, the first housing 10 and the second housing 11 are locked by screwing the first screw 5 and the second housing, and then the first housing and the second housing in the locked state can compress and clamp the damping pad 2, and the length of the nut post 4 is used to control the degree of compression of the damping pad 2. In the present embodiment, the nut stud 4 is fixed to the first substrate 100 by riveting, but may also be fixed by interference fit or welding. It is understood that in other embodiments, other limiting members and fasteners may be used to achieve the above-mentioned limiting and locking functions, for example, a sleeve is used as the limiting member, a xiao Zhou matched with the sleeve is used as the fastener, the first housing and the second housing are locked by interference fit, and the length of the sleeve is used to control the degree of compression of the damping pad. Or, can also use buckle subassembly as locating part and fastener, buckle subassembly generally includes guide part and chucking spare, and guide part guide chucking spare slides along the guide part, slides to realize the block fixed in the draw-in groove on the guide part in the card portion chucking on the chucking spare after reaching the target, consequently can use one of guide part and chucking spare as the locating part, and another is as the fastener, and both blocks realize the locking to first casing and second casing, also can play limiting displacement simultaneously, can control the degree that the damping pad compressed.

Specifically, the length of the limiting member in this embodiment is designed to be three-quarters of the original thickness of the vibration damping pad 2 in the uncompressed state. Through the experiments of the inventor, the length of the limiting member is set to be L, the original thickness of the damping pad 2 is set to be D, L = D × C, C is a coefficient, and C is a selected value between 0.7 and 0.99 according to different materials and the original thickness of the damping pad 2 in an uncompressed state.

The vibration damping support further comprises a connecting piece 3, the connecting piece 3 is provided with a connecting part 30 extending into the vibration damping pad 2, so that the connecting part 30 is fully attached to the vibration damping pad 2, the vibration damping capacity of the vibration damping pad 2 can be better exerted during vibration, and as shown in figures 3 to 6 during application, the vibration damping support in the embodiment is installed on an elevator guide rail 9 through the shell 1 and correspondingly installed on an installation station through the connecting piece 3, wherein the installation station refers to a wall in an elevator shaft or an installation seat installed on the wall. It will be understood that in other embodiments it is also possible to mount the connecting element 3 to the elevator guide rail 9 and the housing 1 to the mounting station. The one of the housing 1 and the connecting element 3 mounted with the elevator guide rails 9 serves to transmit vibration energy, and the other serves to position the damping pad 2. It should be noted that, in the embodiment, as shown in fig. 1 and 2, when the housing 1 and the elevator guide rail 9 are installed, the first housing 10 provided with the stopper is located on the side close to the elevator guide rail 9, and in other embodiments, the second housing 11 may be located on the side close to the elevator guide rail 9.

Although the first base plate 100 and the second base plate 110 can well prevent the vibration pad 2 from sliding relative to the housing 1 by applying a clamping force to the vibration pad 2 along the axial direction of the nut post 4, slight sliding may occur after long-term use, so that in order to better position the vibration pad 2 and prevent the vibration pad 2 from sliding relative to the housing 1, as shown in fig. 2, in the embodiment, the through hole 20 is formed in the vibration pad 2, and the nut post 4 is inserted into the through hole 20, so that the nut post 4 can play a role in positioning the vibration pad 2 along the radial direction thereof, and the vibration damping effect is better ensured. The above-mentioned insertion of the nut post 4 into the through hole 20 means that the outer diameter of the nut post 4 is slightly larger than the hole diameter of the through hole 20 or is substantially the same as both, so that the through hole 20 has a certain pressure action on the nut post 4 due to the elastic deformation capability of the vibration-damping pad 2. It is understood that in other embodiments, the nut post 4 may be disposed on the edge of the first substrate 100 not contacting the vibration damping pad 2, so that the nut post 4 does not penetrate the vibration damping pad 2, and the nut post 4 only has the function of clamping the housing 1 in cooperation with the first screw 5 and the function of limiting the degree of compression of the vibration damping pad 2, and does not have the function of positioning the vibration damping pad 2 in the radial direction as described in the present embodiment. Moreover, when the nut columns 4 are provided at the edge positions of the vibration damping pad 2, the clamping ability of the nut columns 4 to the housing 1 is also reduced correspondingly in the case where the number of the provided nut columns is the same.

The nut post 4 is disposed through the vibration damping pad 2, and correspondingly, the nut post 4 also passes through the connecting portion 30, so as shown in fig. 3, 4, 7 and 8, the connecting portion 30 in this embodiment is also provided with a first connecting hole 300 for passing the nut post 4, since the rigidity of the nut post 4 and the connecting member 3 is relatively high, if the inner wall of the first mounting hole 300 is in rigid contact with the nut post 4, vibration energy cannot be conducted to the vibration damping pad 2, so that a gap is formed between the inner wall of the first connecting hole 300 and the nut post 4 in this embodiment, specifically, the aperture of the first connecting hole 300 is larger than the outer diameter of the nut post 4, and the vibration damping pad 2 is formed with a first elastic limiting portion 21 for preventing the inner wall of the first connecting hole 300 from being in rigid contact with the nut post 4, and the elastic limiting portion 21 extends into the gap. Specifically, in the present embodiment, an annular gasket, which is the first elastic limiting portion 21 described above, is formed on the damping pad 2 in a manner such that the peripheral portion of the through hole 20 protrudes outward.

The vibration damping support is subjected to continuous vibration in the long-time use process, the vibration may cause fretting wear between the first screw 5 and the nut stud 4, which is an important reason causing the failure of the threaded connection, and the vibration damping pad 2 has good elastic deformation capability, and when the fretting wear between the first screw 5 and the nut stud 4 reaches a certain degree, the first shell 10 and the second shell 11 may not be locked (when other limiting members and fastening members are used, the vibration is influenced, and the possibility of looseness exists after the long-time use). As shown in fig. 1 and fig. 2, in order to solve the above problem, in the present embodiment, a first surrounding barrier 101 is formed on a first substrate 100, a second surrounding barrier 111 is formed on a second substrate 110, and the first surrounding barrier 101 and the second surrounding barrier 111 are engaged with each other and are locked and fixed by a locking member. Therefore, by providing the locking members on the first surrounding barrier 101 and the second surrounding barrier 111, the locking capability of the housing 1 is enhanced by the locking members, and the service life of the vibration reduction bracket can be prolonged. In addition, enclose fender 111 through setting up first and enclose fender 101 and second and can also avoid damping pad 2 to expose in the air by a large scale, can effectively prevent like this that damping pad 2 is ageing, also can prolong its life.

Specifically to this embodiment, the retaining member is second screw 6, and the size that the second encloses fender 111 slightly is less than the first size that encloses fender 101 to enclose fender 111 with the second and imbed in the first fender 101 that encloses, and enclose fender 101 and second and all be provided with corresponding pilot hole on keeping off 111 at the first, and be located the second and enclose the internal thread that is provided with second screw 6 looks adaptation in the pilot hole that keeps off 111, specifically, directly set up the internal thread in this pilot hole in this embodiment.

It is understood that the above-mentioned internal threads may be provided in the assembly holes of the first surrounding barrier 101 and the second surrounding barrier 111 to enhance the locking effect. In other embodiments, the size of the first enclosure 101 may be slightly smaller than that of the second enclosure 111, and the first enclosure 101 may be embedded in the second enclosure 111. Also, the internal threads may be formed by fixedly positioning a nut within the mounting hole, such as by pressing the nut into the mounting hole with a tight fit. Of course, the locking member can also use other structures, such as rivets, and the first surrounding barrier and the second surrounding barrier can be directly welded for achieving the purpose of strengthening the locking.

As mentioned above, the firm locking of the first housing 10 and the second housing 11 and the clamping action of the damping pad 2 are important for the service life of the whole damping bracket, so to further enhance the above-mentioned clamping action, in this embodiment, a bolt 7 is further provided to penetrate through the first housing 10, the second housing 11 and the damping pad 2, specifically, mounting holes are provided on the first housing 10, the second housing 11 and the damping pad 2, the bolt 7 penetrates through the mounting holes, and the first housing 10 and the second housing 11 are locked and fixed by the cooperation of the bolt 7 and the nut 70, so as to further enhance the locking between the first housing 10 and the second housing 11. Further, the bolt 7 used in the present embodiment is also used for assembling the housing 1 and the elevator guide rail 9 at the same time, specifically, as shown in fig. 6, the housing 1 and the flap 8 are clamped to both sides of the elevator guide rail 9 by fitting the housing 1 with a clamping flap 8, passing the flap 8 and the housing 1 through the bolt 7, and using the bolt 7. In addition, the installation hole in the embodiment is the oblong hole, so that when facing elevator guide rails 9 with different width sizes, the installation position of the bolt 7 can be conveniently adjusted through the oblong hole, the size of the elevator guide rail 9 can be adapted to different sizes, and the use scenes of the vibration reduction support are increased.
