DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In order to solve the problem that the shock absorption effect of using only springs is poor and cannot provide sufficient protection, please refer to Figure 1-Figure 5 , providing the following preferred technical solutions.

[0030] An embodiment of the present invention is a seismic-proof and durable composite concrete seismic-resistant base, comprising a base 1, a plurality of first installation grooves 101 are evenly arranged on the inner bottom wall of the base 1, a ball 11 is movably connected inside the first installation groove 101, a shock-absorbing seat 12 is movably connected to the upper end of the ball 11, a first shock-absorbing assembly 13 is arranged on the side wall of the shock-absorbing seat 12, three shock-absorbing airbags 14 are evenly fixedly installed on the inner bottom wall of the shock-absorbing seat 12, two second shock-absorbing assemblies 15 are arranged inside the shock-absorbing seat 12, and the second shock-absorbing assemblies 15 are respectively located between the two shock-absorbing airbags 14, a support seat 16 is fixedly connected to the upper end of the support seat 16, a first support plate 161 is fixedly connected to the upper end of the first support plate 161, four third shock-absorbing assemblies 17 are arranged on the upper end of the first support plate 161, and the included angles between the third shock-absorbing assemblies 17 are The third damping assembly 17 comprises a first rotating seat 171, a first connecting column 172 is rotatably connected inside the first rotating seat 171, a third mounting groove 173 is provided at one end of the first connecting column 172 away from the first rotating seat 171, a third spring 174 is fixedly connected to the inner wall of the third mounting groove 173, one end of the third spring 174 is fixedly connected to the second connecting column 175, the second connecting column 175 is slidably connected to the inner wall of the third mounting groove 173, one end of the second connecting column 175 is rotatably connected to the second rotating seat 176, the second rotating seat 176 is fixedly connected to the upper end of the first support plate 161, the upper end of the first rotating seat 171 is fixedly connected to the second support plate 19, the upper end of the second support plate 19 is fixedly connected to the connecting seat 191, and the upper end of the connecting seat 191 is fixedly connected to the mounting seat 2.

[0031] Specifically, when the base 1 vibrates and shakes horizontally, the ball 11 is used to convert the sliding friction between the base 1 and the shock-absorbing seat 12 into rolling friction, and at the same time, the first shock-absorbing assembly 13 is used to perform the first shock absorption on the base 1, thereby reducing the shaking amplitude of the shock-absorbing seat 12, and then the shock-absorbing airbag 14 and the second shock-absorbing assembly 15 in the shock-absorbing seat 12 are used for shock absorption. The aftershocks after the shock absorption by the first shock-absorbing assembly 13, the shock-absorbing airbag 14 and the second shock-absorbing assembly 15 are transmitted to the third shock-absorbing assembly 17 through the support seat 16 and the first support plate 161, so that the second rotating seat 176 squeezes the third spring 174 through the second connecting column 175, causing the third spring 174 to undergo elastic deformation, thereby consuming the remaining vibration energy, and then damping the precision equipment on the upper end of the mounting seat 2 to reduce damage caused by vibration.

[0032] Eight fourth shock absorbing assemblies 18 are arranged at the lower end of the second supporting plate 19, and the fourth shock absorbing assemblies 18 are respectively located on both sides of the third shock absorbing assembly 17, and the fourth shock absorbing assembly 18 includes a third connecting column 181, and a fourth mounting groove 182 is opened at one end of the third connecting column 181, and a fourth spring 183 is fixedly connected to the inner wall of the fourth mounting groove 182, and a fourth connecting column 184 is fixedly connected to one end of the fourth spring 183, and the fourth connecting column 184 is slidably connected to the inner wall of the fourth mounting groove 182, and a first connecting plate 185 is fixedly connected to one end of the fourth connecting column 184, and the second connecting plate 186 is rotatably connected to the upper end of the first connecting plate 185, and the end of the second connecting plate 186 away from the first connecting plate 185 is rotatably connected to the third connecting plate 187, and the end of the third connecting plate 187 away from the second connecting plate 186 is fixedly connected to the second supporting plate 19.

[0033] Specifically, when the precision equipment on the upper end of the mounting seat 2 vibrates, the vibration is transmitted to the third connecting plate 187 through the second support plate 19, and the third connecting plate 187 moves downward, so that the third connecting plate 187 drives the second connecting plate 186 to rotate, and the second connecting plate 186 drives the first connecting plate 185 to move linearly, so that the first connecting plate 185 drives the fourth connecting column 184 to squeeze the fourth spring 183 in the fourth mounting groove 182 for shock absorption.

[0034] The second shock absorbing assembly 15 includes a third mounting plate 151, which is fixedly connected to the inner bottom wall of the shock absorbing seat 12, a plurality of telescopic rods 152 are evenly fixedly connected to the upper end of the third mounting plate 151, an end of the telescopic rod 152 away from the third mounting plate 151 is fixedly connected to a fourth mounting plate 153, the fourth mounting plate 153 is fixedly connected to the lower end of the support seat 16, a second spring 154 is movably sleeved on the side wall of the telescopic rod 152, and both ends of the second spring 154 are respectively fixedly connected to the third mounting plate 151 and the fourth mounting plate 153.

[0035] Specifically, when up and down vibrations occur, the fourth mounting plate 153 is squeezed by the support seat 16, so that the fourth mounting plate 153 squeezes the telescopic rod 152 and the second spring 154, causing the second spring 154 to undergo elastic deformation, thereby performing shock absorption. At the same time, when the shock-absorbing airbag 14 leaks or is damaged, the shock-absorbing airbag 14 cannot support the support seat 16, and then uses the second spring 154 for support, thereby preventing the precision equipment at the upper end of the mounting seat 2 from instantly shifting downward, thereby causing losses.

[0036] The first shock absorbing assembly 13 includes a first mounting plate 131, which is fixedly connected to the side wall of the shock absorbing seat 12, and a plurality of first springs 132 are evenly fixedly connected to the side wall of the first mounting plate 131 away from the shock absorbing seat 12, and one end of the first spring 132 away from the first mounting plate 131 is fixedly connected to the second mounting plate 133, and the second mounting plate 133 is fixedly connected to the inner wall of the base 1.

[0037] Specifically, when the shock absorbing seat 12 shakes in the horizontal direction, the shock absorbing seat 12 squeezes the first spring 132 through the first mounting plate 131, so that the first spring 132 undergoes elastic deformation, thereby performing shock absorption.

[0038] The inner side walls of the base 1 are each provided with a slide groove 102 , and one end of the third connecting column 181 away from the fourth connecting column 184 is fixedly connected to a limiting block 188 , and the limiting block 188 is slidably connected to the slide groove 102 .

[0039] Specifically, by sliding the limit block 188 in the slide groove 102, the linear motion of the third connecting column 181 is realized. When the precision equipment on the upper end of the mounting seat 2 shakes horizontally, the second support plate 19 can drive the two groups of fourth shock absorbing components 18 to reduce shock, and at the same time drive the other two groups of fourth shock absorbing components 18 to adjust their positions in the horizontal direction to avoid deformation.

[0040] Furthermore, in order to enhance the stability of the device, increase the shock absorption effect, and increase the stability of the instrument, such as Figure 5-Figure 8 As shown, the following preferred technical solutions are provided.

[0041] The distance that the shock-absorbing airbag 14 drives the support seat 16 to adjust its position in the vertical direction is smaller than the distance between the support seat 16 and the lower end of the first connecting plate 185 .

[0042] The inner bottom wall of the shock absorbing seat 12 is provided with three second mounting grooves 121, and the second mounting grooves 121 are respectively located directly below the shock absorbing airbags 14. A pressure sensor 122 is fixedly installed on the inner wall of the second mounting groove 121, and the upper end of the pressure sensor 122 is in contact with the shock absorbing airbag 14. The pressure applied by the shock absorbing airbag 14 to the inner bottom wall of the shock absorbing seat 12 is detected by the pressure sensor 122, and then it is determined whether the shock absorbing airbag 14 is leaking or damaged according to the value detected by the pressure sensor 122, without the need for workers to disassemble the entire device for inspection.

[0043] A fifth mounting groove 192 is provided on the side wall of the connecting seat 191, and a rubber frame 193 is fixedly connected to the inner wall of the fifth mounting groove 192. The rubber frame 193 abuts against the side wall of the port of the base 1, and is used to utilize the rubber frame 193 to cushion the impact of the connecting seat 191 on the port of the base 1 when it shakes horizontally, thereby reducing the noise generated by the impact and increasing the sealing of the connection between the connecting seat 191 and the port of the base 1.

[0044] The shock-absorbing airbag 14 is connected to an air pump through an air pipe, and the pressure sensor 122 is electrically connected to an external controller, which is used to receive the signal transmitted by the pressure sensor 122 through the controller, and control the air pump to inflate the airbag through the electrical signal output by the controller, thereby adjusting the vertical position of the mounting seat 2.

[0045] The inner cavities of the support seat 16, the base 1 and the shock-absorbing seat 12 are all T-shaped structures, and a distance is left between the side wall of the second support plate 19 and the inner wall of the base 1. The second support plate 19 and the T-shaped support seat 16 are used to limit the connection seat 191 and the support seat 16 from being separated from the base 1 and the shock-absorbing seat 12 respectively. Secondly, a distance is left between the side wall of the second support plate 19 and the inner wall of the base 1, so that when the base 1 shakes in the horizontal direction, the inner wall of the base 1 and the shock-absorbing seat 12 are indirectly separated, thereby reducing the impact of the horizontal shaking of the base 1 on the shock-absorbing seat 12, thereby increasing the stability of the precision equipment on the upper end of the mounting seat 2.

[0046] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
