"Through the first sliding rod, the first spring, the sleeve plate and the trigger rod arranged, a simple buffer trigger mechanism can be formed, which can make the elevator car gradually contact the overload detector body when gaining weight, reduce the damage to the detection end, and play a certain protective role. Through the damping cylinder composed of the installation cylinder, the damping pad, the second spring and the second sliding rod arranged, the gravity of the elevator car pressing down can be slowed down, preventing the overload from causing extrusion damage to the overload detector body and other components."

[0025] Among them, the detection component 100 includes a bottom plate 101, a load-bearing plate 102 is installed at the upper end of the bottom plate 101, several buffer seats 103 are connected between the bottom plate 101 and the load-bearing plate 102, gravity sensors 104 are installed at the upper ends of several buffer seats 103, a sensor contact 105 is connected to the upper end of the gravity sensor 104, a buzzer 106 is embedded in the interior of the bottom plate 101, a buffer spring 107 is connected between the bottom plate 101 and the load-bearing plate 102, several first screw holes 108 are opened at the upper end of the bottom plate 101, screws 109 are threadedly connected inside several first screw holes 108, two limit nuts 110 are threadedly connected to the side surface of the screw 109, and an anti-slip rib 120 is connected to the upper end of the load-bearing plate 102.

[0026] In a specific embodiment, the detection component 100 not only can achieve multiple buffer protection effects, improve the stability of the detection device, but also facilitate the disassembly of each component, thereby improving the use convenience of the detection device. In addition, through the cooperation of the above structures, it is also convenient to accurately detect the weight of passengers, thereby improving the use safety of the detection device. When in use, first install the detection component 100 inside the elevator car, and at the same time pass several screws 109 through the first screw holes 108 and threadedly connect them with the elevator car, thereby initially enhancing the installation strength of the load-bearing plate 102. At the same time, the limit nuts 110 are threadedly connected to the upper and lower ends of the screw 109, so the connection strength between the screw 109 and the bottom plate 101 can be further enhanced. When a person stands on the upper end of the load-bearing plate 102 when taking the elevator, the load-bearing plate 102 is forced to press down the buffer spring 107 and several buffer seats 103. Through the buffer spring 107 and several buffer seats 103, the descending speed of the load-bearing plate 102 can be slowed down, thus playing a protective role. At the same time, when the load-bearing plate 102 is pressed down, several gravity sensors 104 cooperate with the sensor contact 105 to accurately measure the total weight of the person. When the total weight exceeds the preset threshold, the buzzer 106 emits a beeping alarm, thereby improving the use safety of the detection device. When disassembling, first take out the screw 109 from the first screw hole 108, so that the bottom plate 101 can be disassembled, thus improving the disassembly convenience of the detection component 100.

Several limit holes 113 are opened at the lower end of the load-bearing plate 102, and the sensor contact 105 is clamped in the interior of the limit holes 113.

[0028] In a specific embodiment, the insertion block 111 is inserted into the insertion hole 112, which not only facilitates the connection of the buffer spring 107, the bottom plate 101 and the load-bearing plate 102, but also enables the removal of the insertion block 111 to disassemble the buffer spring 107.

[0029] Please refer to Figures 2-6 , an installation groove 121 is formed at the upper end of the bottom plate 101, and the buzzer 106 is installed inside the installation groove 121.

[0030] In a specific embodiment, the installation groove 121 not only facilitates the installation and limitation of the buzzer 106, but also improves the protection strength of the buzzer 106.

[0031] Please refer to Figures 2-6 , a plurality of second screw holes 131 are formed at the upper end of the bottom plate 101, and the lower ends of a plurality of buffer seats 103 are fixedly connected with second bolts 132, and the second bolts 132 are threadedly connected inside the second screw holes 131.

[0032] In a specific embodiment, the threaded connection of the second bolt 132 inside the second screw hole 131 can enhance the connection strength between the buffer seat 103 and the bottom plate 101 and improve the protection effect on the detection device.

[0033] Please refer to Figures 2-6 , an annular groove 141 is formed at the upper end of the bottom plate 101, and a limiting ring 142 is fixedly connected to the lower end of the buffer seat 103, and the limiting ring 142 is clamped inside the annular groove 141.

[0034] In a specific embodiment, the clamping of the limiting ring 142 inside the annular groove 141 can improve the limiting strength of the buffer seat 103. After removing the limiting ring 142 and the second bolt 132 from the second screw hole 131, the buffer seat 103 can be disassembled.

[0035] Please refer to Figures 2-6 , a clamping groove 151 is formed at the upper end of the buffer seat 103, and a clamping block 152 is fixedly connected to the lower end of the gravity sensor 104, and the clamping block 152 is clamped inside the clamping groove 151.

[0036] In a specific embodiment, the clamping of the clamping block 152 inside the clamping groove 151 can improve the installation stability between the gravity sensor 104 and the buffer seat 103. After removing the clamping block 152, the gravity sensor 104 can be disassembled.

[0037] Please refer to Figures 2-6 , the buffer seat 103 is made of rubber, and the load-bearing plate 102 is made of frosted material.

[0038] In a specific embodiment, the buffer seat 103 made of rubber can enhance the friction between the buffer seat and the bottom plate 101, further improving the buffering effect.

Then, thread the limit nuts 110 at the upper and lower ends of the screws 109 to further enhance the connection strength between the screws 109 and the bottom plate 101. When a person stands on the load-bearing plate 102 in the elevator, the load-bearing plate 102 is pressed downward, compressing the buffer springs 107 and a number of buffer seats 103. The buffer springs 107, in cooperation with a number of buffer seats 103, can slow down the descending speed of the load-bearing plate 102, thereby enhancing the protection performance of the detection device and other components. At this time, the load-bearing plate 102 presses down a number of gravity sensors 104, and in cooperation with the sensor contacts 105, it can accurately measure the total weight of the person. When the total weight exceeds the preset threshold, the buzzer 106 emits a beeping alarm to improve the safety of use of the detection device.
