In construction projects, the use of steel structures is indispensable. The use of steel structures can play a reinforcement role. Steel structures are strong and light in weight. Steel structures have great deformation capacity. During the use of steel structures, they will inevitably be affected by earthquakes, so earthquake-resistant bases will be used.

[0003] After searching, the patent with announcement number CN220686323U discloses a seismic base for construction engineering with a protective structure, including a connection component and a seismic base, wherein the connection component is located inside the seismic base, and the connection component includes a connector and a square plate, wherein the bottom of the connector is fixedly connected to the top of the square plate. The utility model sets structural components such as a connection component, a connector, a square plate, a seismic base, an upper shell, a lower shell and a plug-in block, wherein the connection component is used to connect the steel structure, and through the use of the seismic base, the connection component after the steel structure is connected can be seismically protected, and through the use of the positioning component, the U-shaped block can be moved to and removed from the inside of the plug-in block, so that the upper shell and the lower shell can be fixed and separated, thereby achieving the effect of seismic protection for the steel structure, and solving the problem that the steel structure is easily damaged by long-term vibration when there is no seismic base used in conjunction with the steel structure.

[0004] The technical solution has the following problems:

[0005] When the use status of the shock absorbing assembly needs to be checked, the two pull rods need to be manually pulled in sequence to make the two U-shaped blocks leave the upper shell so as to release the fixation of the upper shell, which is troublesome and the efficiency of removing the upper shell is low. Utility Model Content

[0006] The purpose of the utility model is to solve the problems in the prior art that when it is necessary to check the use status of the shock absorbing assembly, it is necessary to manually pull two pull rods in sequence to make the two U-shaped blocks leave the upper shell in order to release the fixation of the upper shell, which is rather troublesome and the efficiency of removing the upper shell is low. A seismic resistant base with a protective structure is proposed to solve the problems in the prior art.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A seismic resistant base with a protective structure, comprising a lower shell and an upper shell, wherein dampers for buffering and absorbing shock of a steel structure are fixedly arranged at four corners of the bottom inner wall of the lower shell, a same fixing plate is fixedly arranged at the top ends of the four dampers, a second spring is sleeved on the four dampers, the bottom end of the second spring is fixedly connected to the bottom inner wall of the lower shell, the top end of the second spring is fixedly connected to the bottom of the fixing plate, a connecting piece for facilitating connection with the steel structure is fixedly arranged on the top of the fixing plate, a through hole is opened at the top of the upper shell, and the upper shell is movably sleeved on the connecting piece;

[0009] A fixing mechanism, which is arranged on the lower shell and is used to fix the upper shell;

[0010] The limiting mechanism is arranged on the lower shell and is used to limit the upper shell to improve the fixing effect.

[0011] In a possible design, the fixing mechanism includes a pull pin, a first spring, a clamp, a first support plate and a second support plate. A circular hole is opened on one side of the lower shell, and the outer side of the pull pin is slidably connected to the inner wall of the circular hole. The first spring is sleeved on the pull pin, and one side of the first support plate is fixedly connected to the inner wall of one side of the lower shell, and one side of the second support plate is fixedly connected to the inner wall of one side of the lower shell. The bottom of the clamp is slidably connected to the top of the second support plate, one end of the pull pin is fixedly connected to one side of the clamp, one end of the first spring is fixedly connected to the inner wall of one side of the lower shell, and the other end of the first spring is fixedly connected to one side of the clamp, and the upper shell is located on the first support plate and the second support plate.

[0012] In a possible design, the limiting mechanism includes two first plug blocks and two second plug blocks, one side of the two first plug blocks is fixedly connected to one side of the lower shell, one side of the two second plug blocks is fixedly connected to one side of the clamping plate, and two sockets are provided on both sides of the upper shell, and the first plug blocks and the second plug blocks are both plugged into the sockets.

[0013] In a possible design, mounting plates are fixedly provided on both sides of the lower shell to facilitate installation.

[0014] In a possible design, a pull ring is fixedly provided at one end of the pull pin for facilitating pulling the pull pin to move.

[0016] In the present application, when in use, the pull ring is pulled, and the movement of the pull ring drives the movement of the pull pin, and the movement of the pull pin drives the movement of the splint, and the movement of the splint drives the movement of the two second plug blocks. At this time, the first spring is compressed, and the upper shell is sleeved on the connecting piece and placed on the first support plate and the second support plate, and then the upper shell is slightly moved toward the first support plate to insert the first plug block into the socket of the upper shell, and then the hand pulling the pull ring is released, and the compressed first spring is released, and the splint is pushed to move by the thrust of the first spring, so that the second plug block is inserted into the socket on the other side of the upper shell, so that the upper shell can be fixed, and the upper shell can be limited by the setting of the first plug block, the second plug block and the socket, thereby improving the fixation. The steel structure is connected to the connecting piece and fixed with bolts. When the steel structure is vibrated, the fixing plate moves up and down between the upper shell and the lower shell, causing the second spring to deform and the damper to expand and contract. The second spring pushes the steel structure to restore its initial position, thereby reducing shock. When the upper shell needs to be removed to check the use of the damper and the second spring, the pull ring is pulled by hand. The movement of the pull ring drives the splint and the second plug block to move, so that the second plug block leaves the socket of the upper shell. The upper shell is moved to the left by hand to make the first plug block leave the socket on the other side of the upper shell. The upper shell is pulled upward, so that the upper shell can be disassembled, and there is no need to pull the two pull rods in sequence, thereby improving efficiency.
