Description

Technical Field

[0001] This utility model relates to the field of rubber technology, specifically to lead-indium composite vibration isolation rubber bearings. Background Technology

[0002] Lead cores are used in the production of lead-core seismic isolation rubber bearings for buildings and bridges, and these lead cores pollute the environment.

[0003] While existing seismic isolation rubber bearings can improve the seismic resistance of buildings and bridges, traditional seismic isolation rubber bearings are more polluting, which can impact the surrounding environment over time. They also cannot be installed at a height that requires a lot of time to adjust during construction. Therefore, lead-indium composite seismic isolation rubber bearings have been introduced. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lead-indium composite vibration isolation rubber bearing, which has the advantages of good environmental performance and good adjustability, and solves the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a lead-indium composite vibration isolation rubber bearing, including a connecting steel plate, an adjustment component provided on the inner wall of the connecting steel plate, a pre-embedded rib fixedly mounted on the top of the connecting steel plate, a steel plate layer, an indium core and a protective layer fixedly mounted on the inner wall of the connecting steel plate respectively, and a sealing ring fixedly mounted on the outer wall of the protective layer.

[0006] As a preferred technical solution of this utility model: the adjusting component includes a sleeve, a connecting rod is slidably connected to the inner wall of the sleeve, a limiting plate is fixedly assembled at one end of the connecting rod, a rotating device is fixedly assembled at the other end of the connecting rod, a threaded rod is fixedly assembled at the end of the limiting plate away from the connecting rod, and a fixing post is threadedly connected to the outer wall of the threaded rod.

[0007] As a preferred technical solution of this utility model: the sealing ring is fixedly assembled with the outer wall of the connecting steel plate, and the connecting rod is slidably connected with the inner wall of the connecting steel plate.

[0008] As a preferred technical solution of this utility model: the indium core is located at the center of the inner wall of the steel plate layer, and the diameter of the limiting plate is larger than the inner wall diameter of the sleeve.

[0009] As a preferred technical solution of this utility model: the sleeve is fixedly assembled with the bottom of the connecting steel plate, and the steel plate layer is located between the indium core and the protective layer.

[0010] As a preferred technical solution of this utility model: the number of adjustment components is several sets, and the several sets of adjustment components are respectively located on the inner wall of the connecting steel plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This lead-indium composite vibration isolation rubber bearing uses an indium core, which is a relatively inert metal with good corrosion resistance. Therefore, using an indium core can improve the corrosion resistance of the bearing and extend its service life. Furthermore, the indium core will not pollute the surrounding environment during long-term use. At the same time, the sealing ring seals the connection between the connecting steel plate and the protective layer, preventing impurities from entering the inner wall of the steel plate layer and damaging the equipment during installation. This achieves an environmental protection effect and also extends the service life of the equipment.

[0013] 2. When adjusting the height of the connecting steel plate in this lead-indium composite seismic isolation rubber bearing, the operator rotates the rotating device. This causes the rotating device to rotate on the inner wall of the connecting steel plate under force. Simultaneously, the rotation of the rotating device drives the threaded rod to rotate. The threaded rod rotates on the inner wall of the fixed column, causing the threaded rod to move the limiting plate upwards. The moving limiting plate applies pressure to the sleeve, which in turn applies pressure to the connecting steel plate. By performing the same operation on multiple sets of adjusting components, the operator can adjust the height of the seismic isolation rubber bearing. Furthermore, the installed embedded ribs and adjusting components improve the mechanical performance of the equipment. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 5 The lead-indium composite vibration isolation rubber bearing includes a connecting steel plate 1, an adjustment component 6 on the inner wall of the connecting steel plate 1, a pre-embedded rib 2 fixedly mounted on the top of the connecting steel plate 1, a steel plate layer 3, an indium core 4 and a protective layer 7 fixedly mounted on the inner wall of the connecting steel plate 1, and a sealing ring 5 fixedly mounted on the outer wall of the protective layer 7.

[0023] In the above structure, indium core 4, as a metal with low chemical activity, exhibits excellent corrosion resistance. Therefore, the application of indium core 4 can improve the corrosion resistance of the support and help extend its service life. In addition, indium core 4 will not cause environmental pollution during long-term use. At the same time, by implementing the sealing ring 5, the connection between the connecting steel plate 1 and the protective layer 7 can be effectively sealed to prevent impurities from entering the inner wall of the steel plate layer 3 during installation, avoid damage to the equipment, and achieve environmental protection goals.

[0024] In a preferred embodiment: the adjusting component 6 includes a sleeve 601, a connecting rod 605 is slidably connected to the inner wall of the sleeve 601, a limiting plate 604 is fixedly mounted at one end of the connecting rod 605, a rotating device 606 is fixedly mounted at the other end of the connecting rod 605, a threaded rod 602 is fixedly mounted at the end of the limiting plate 604 away from the connecting rod 605, and a fixing post 603 is threadedly connected to the outer wall of the threaded rod 602.

[0025] In the above structure, during the adjustment of the height of the connecting steel plate 1, the operator rotates the rotating device 606, causing it to rotate on the inner wall of the connecting steel plate 1. As the rotating device 606 rotates, it drives the threaded rod 602 to rotate accordingly. Consequently, the threaded rod 602 rotates threadedly on the inner wall of the fixed column 603. This action causes the threaded rod 602 to move the limiting plate 604 upward. During the movement, the limiting plate 604 applies pressure to the sleeve 601, ultimately causing the sleeve 601 to apply pressure to the connecting steel plate 1. By performing the same operation on multiple sets of adjusting components 6, the height of the vibration isolation rubber bearing can be adjusted. In addition, by installing the embedded ribs 2 and adjusting components 6, the mechanical performance of the equipment can be further improved.

[0026] In a preferred embodiment: the sealing ring 5 is fixedly assembled with the outer wall of the connecting steel plate 1, and the connecting rod 605 is slidably connected with the inner wall of the connecting steel plate 1.

[0027] In the above structure, the connecting steel plate 1 is used to limit the connecting rod 605 so that the connecting rod 605 will not fall off when it moves on the inner wall of the connecting steel plate 1. The sealing ring 5 is fixedly assembled to the protective layer 7 and the connecting steel plate 1 respectively, so that the sealing ring 5 has better sealing performance when placed.

[0028] In a preferred embodiment: the indium core 4 is located at the center of the inner wall of the steel plate layer 3, and the diameter of the limiting plate 604 is larger than the inner wall diameter of the sleeve 601.

[0029] In the above structure, the indium core 4 is limited by the steel plate layer 3, making the indium core 4 more stable when placed. The diameter of the limiting plate 604 is larger than the inner wall diameter of the sleeve 601, so that the limiting plate 604 will apply pressure to the sleeve 601 and the connecting steel plate 1 when it moves or rotates.

[0030] In a preferred embodiment: the sleeve 601 is fixedly assembled to the bottom of the connecting steel plate 1, and the steel plate layer 3 is located between the indium core 4 and the protective layer 7.

[0031] In the above structure, the adjusting component 6 is limited by the connecting steel plate 1, making the adjusting component 6 more stable when placed and preventing it from falling. The protective layer 7 protects the steel plate layer 3 and the indium core 4 to prevent damage to the steel plate layer 3 and the indium core 4 during placement. The indium core 4 limits and protects the steel plate layer 3 to prevent it from tilting during use.

[0032] In a preferred embodiment, there are several sets of adjusting components 6, and the several sets of adjusting components 6 are respectively located on the inner wall of the connecting steel plate 1.

[0033] In the above structure, several sets of adjustment components 6 are used to limit and support the connecting steel plate 1, the embedded rib 2, the steel plate layer 3, the indium core 4 and the sealing ring 5, so that the equipment is more stable when placed or operated and will not collapse. At the same time, the equipment will not fall when adjusting the adjustment components 6, and the indium core 4 and the lead core can be interchanged.

[0034] Working Principle: Indium core 4 is known for its relatively low chemical activity and excellent corrosion resistance. Therefore, using indium core 4 can enhance the corrosion resistance of the support and extend its service life. In addition, indium core 4 will not cause environmental pollution during long-term use. By using the sealing ring 5, the connection between the connecting steel plate 1 and the protective layer 7 can be sealed, preventing impurities from entering the inner wall of the steel plate layer 3 during installation, thereby avoiding damage to the equipment and achieving environmental protection. At the same time, this also helps to extend the service life of the equipment. When adjusting the height of the connecting steel plate 1, the operator rotates the rotating device 606. This causes the rotating device 606 to rotate on the inner wall of the connecting steel plate 1. As the rotating device 606 rotates, it drives the threaded rod 602 to rotate as well. During the rotation, the threaded rod 602 rotates on the inner wall of the fixed column 603, thereby pushing the limiting plate 604 to move upward. As the limiting plate 604 moves, it applies pressure to the sleeve 601, causing the sleeve 601 to press against the connecting steel plate 1. By having the operator perform the same operation on multiple sets of adjusting components 6, the height of the vibration isolation rubber bearing can be adjusted. In addition, by installing the embedded ribs 2 and adjusting components 6, the mechanical performance of the equipment can be further improved.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
