[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Refer to Figure 1 - Figure 2 , an embodiment provided by the present invention: a seismic isolation device for facilitating the installation of an alarm device, including a seismic isolation frame 1. An installation base 2 is arranged inside the seismic isolation frame 1. A spring is fixedly connected to the outside of the installation base 2. A hook is fixedly connected to the inner wall surface of the seismic isolation frame 1. One end of the spring away from the installation base 2 is connected to the hook, which can limit the installation base 2. A detection groove 3 is provided on the upper surface of the installation base 2. A sliding block 4 is arranged above the installation base 2. A longitudinal track is arranged on the upper side inside the seismic isolation frame 1. A transverse track is arranged on the lower side inside the seismic isolation frame 1. The upper part of the transverse track is embedded in the lower chute of the installation base 2. The lower part of the longitudinal track is embedded in the upper chute of the sliding block 4. The transverse track and the longitudinal track are vertically distributed. The installation base 2 can move horizontally along the transverse track, and the sliding block 4 can move longitudinally along the longitudinal track. The sensor unit can detect and count the forces, frictions, and moving distances between the installation base 2 and the sliding block 4 and the transverse track and the longitudinal track. The sensor unit will transmit the data to the MCU motion unit. When the seismic isolation frame 1 operates abnormally, the MCU motion unit will control the alarm unit to alarm and ring. This is a prior art means in this field and will not be elaborated here.

[0034] Refer to Figure 3 - Figure 5, a groove 5 is formed on the bottom surface of the sliding block 4, an elastic member 6 is fixedly connected to the top surface of the groove 5, and the bottom end of the elastic member 6 is fixedly connected to a detection box 7. When the detection box 7 moves upward, the elastic member 6 can be squeezed, causing the elastic member 6 to compress and generate elastic potential energy. At the same time, the detection box 7 will move upward into the groove 5. The detection box 7 is sleeved inside the detection groove 3. When the detection box 7 enters the inside of the detection groove 3, it will limit the sliding block 4, so that the sliding block 4 is stably installed above the mounting seat 2. Sensor units are fixedly connected to the inner wall surfaces around the detection groove 3. The end of the sensor unit away from the inner wall of the detection box 7 is in contact with the outer wall of the detection box 7. When the transverse track and the longitudinal track deform and move, they will drive the sliding block 4 and the mounting seat 2 to move synchronously. At this time, the detection box 7 will move relatively inside the detection groove 3, and the detection box 7 will squeeze the sensor unit, enabling the sensor unit to detect and count the required data. A connecting rope 8 is fixedly connected to the center of the inner bottom surface of the detection box 7. When the connecting rope 8 moves, it can drive the detection box 7 to move synchronously. A guiding unit is arranged on the outer side of the connecting rope 8. The guiding unit includes a mounting frame 81. The mounting frame 81 is fixedly connected to the center of the top surface of the groove 5. A pulley 82 is rotatably connected inside the mounting frame 81. The connecting rope 8 is wound around and passes through the pulley 82. By setting the guiding unit, the direction of the force of the connecting rope 8 can be changed. When the connecting rope 8 is pulled to the left, it will drive the detection box 7 to move upward. When the detection box 7 moves upward and enters the inside of the groove 5, the limit between the mounting seat 2 and the sliding block 4 will be released, enabling the mounting seat 2 and the sliding block 4 to be disassembled alternately.

[0035] A winding unit is arranged on the left side of the sliding block 4. The winding unit includes a fixing plate 91. The fixing plate 91 is fixedly connected to the left surface of the sliding block 4. A lead screw 92 is arranged above the fixing plate 91. The bottom end of the lead screw 92 penetrates through the fixing plate 91, and the lead screw 92 is threadedly connected to the fixing plate 91. When the lead screw 92 rotates, it can perform a linear motion in the up and down directions relative to the fixing plate 91. The end of the connecting rope 8 away from the detection box 7 penetrates through the sliding block 4, and the end of the connecting rope 8 away from the detection box 7 is fixedly connected to the outer surface of the lead screw 92. A circular plate 93 is fixedly connected to the top end of the lead screw 92. The staff can drive the lead screw 92 to rotate through the circular plate 93. When the lead screw 92 rotates and moves downward, it can drive the connecting rope 8 to wind around the outer side of the lead screw 92. At the same time, when the lead screw 92 moves downward, the connecting rope 8 can be spirally wound from bottom to top, avoiding knotting and affecting the movement of the connecting rope 8.

[0036] When the mounting seat 2 and the sliding block 4 need to be disassembled to inspect the sensor unit, the rotatable circular plate 93 drives the connecting rope 8 to be wound around the outside of the screw rod 92, and then drives the detection box 7 to move upward and away from the inside of the detection groove 3 through the cooperation of the guide unit, so as to quickly release the connection between the mounting seat 2 and the sliding block 4, so that the mounting seat 2 and the sliding block 4 can be disassembled in an staggered manner, which is easy to operate and avoids the mounting seat 2 and the sliding block 4 being installed inside the transverse track and the longitudinal track, and being blocked and obstructed, resulting in difficulty in disassembly and maintenance.

[0037] Reference Figure 5 - Figure 6 An upper limit plate 10 is fixedly connected to the upper side of the left surface of the sliding block 4, and the upper surface of the circular plate 93 is in contact with the bottom surface of the upper limit plate 10. A circular hole 11 is provided on the upper surface of the upper limit plate 10, and a lower limit plate 12 is fixedly connected to the lower side of the left surface of the sliding block 4. The upper limit plate 10 and the lower limit plate 12 can guide and limit the movement of the screw rod 92 and the circular plate 93 to prevent the connecting rope 8 from exceeding the movement limit, resulting in a break in the connection between the connecting rope 8 and the detection box 7 or the screw rod 92. A cross groove 13 is provided on the upper surface of the circular plate 93, and the circular hole 11 is located directly above the cross groove 13. The cross groove 13 can be exposed through the circular hole 11. At this time, the staff can use a cross screwdriver to rotate the circular plate 93, which is further convenient for disassembly of the sliding block 4.

[0038] Working principle: When the sensor unit needs to be inspected after long-term use, a cross screwdriver can be passed through the round hole 11 to twist the round plate 93 to drive the screw rod 92 to rotate, so that the connecting rope 8 is wrapped around the outside of the screw rod 92, and the connecting rope 8 is reeled up. Through the cooperation of the set guide unit, the detection box 7 is pulled into the groove 5, and the connection between the sliding block 4 and the mounting seat 2 is quickly released, so that the sliding block 4 and the mounting seat 2 can be disassembled alternately, avoiding the sliding block 4 and the mounting seat 2 being arranged inside the seismic isolation frame 1, and most of the area of ​​the sliding block 4 and the mounting seat 2 is blocked, resulting in difficulty in disassembly and maintenance of the sensor unit.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
