[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 2The utility model provides an embodiment: a stable structure for weighing scales, including a foundation 1, a double-headed motor 10 is fixedly connected to one side of the foundation 1, a rotating shaft 11 is fixedly connected to the output ends of the double-headed motor 10, a worm 12 is fixedly connected to one end of the rotating shaft 11, a transmission shaft 9 is rotatably connected to both sides of the foundation 1, a worm wheel 13 is fixedly connected to one side of the outer wall of the transmission shaft 9, the worm wheel 13 is meshed with the worm 12, a rectangular array of gears 8 is fixedly connected to the outer wall of the transmission shaft 9, a rectangular array of annular chute 4 is opened on both sides of the foundation 1, a rectangular array of fixing hooks 6 are arranged on both sides of the foundation 1, a rack 7 is fixedly connected to the outer wall of the fixing hook 6, and the rack 7 is meshed with the gear 8;

[0024] Specifically, a double-headed motor 10 is used to drive the rotating shaft 11, which in turn drives the worm 12 on both sides to rotate. In this process, the worm 12 plays a key role. Its rotation drives the worm wheel 13 to rotate. The worm wheel 13 is connected to the transmission shaft 9, so that the transmission shaft 9 rotates with the rotation of the worm wheel 13. In addition, the rotation of the worm wheel 13 also synchronously drives multiple gears 8 to rotate. These gears 8 are connected to the rack 7, and the rack 7 is responsible for driving the fixed hook 6 to move. When the gear 8 rotates, the fixed hook 6 will slide out along the annular groove 4 opened inside the foundation 1, so that the fixed hook 6 is inserted into the ground to fix the foundation 1. This design scheme achieves a firm fixation of the foundation 1 through a series of transmission and linkage during the process of burying the foundation 1 in the ground.

[0025] Reference Figure 1 and Figure 3 , an auxiliary component is arranged on the top of the foundation 1, the auxiliary component includes an inclined plate 5 and an anti-skid pattern 3, the bottom of the inclined plate 5 is fixedly connected to the top of the foundation 1, the anti-skid pattern 3 is opened on the top of the inclined plate 5, a rectangular array of measuring brackets 14 is fixedly connected inside the foundation 1, a weighing plate 2 is fixedly connected to the top of the measuring bracket 14, and the anti-skid pattern 3 is opened on the top of the weighing plate 2;

[0026] Specifically, the floor scale adopts a traditional sinking floor scale, with a measuring bracket 14 supporting the weighing plate 2. The weight on the weighing plate 2 can be measured by a sensor arranged inside the measuring bracket 14 for weighing. An inclined plate 5 is arranged on the top of the foundation 1 to facilitate the measurement of vehicles driving in or out. Anti-skid grooves 3 are arranged on the top of the inclined plate 5 and the weighing plate 2 to effectively prevent the measuring vehicle from slipping.

[0027] Reference Figure 3 and Figure 4A buffer plate 16 is slidably connected inside the foundation 1, a gasket 15 is fixedly connected to the top of the buffer plate 16, a transmission rod 18 of a rectangular array is rotatably connected to the bottom of the buffer plate 16, a rectangular array of slide rails 17 are fixedly connected to the bottom wall of the foundation 1, a slider 20 is slidably connected to the outer wall of the slider 20, one side of the transmission rod 18 is rotatably connected to the outer wall of the slider 20, a spring damper 19 is rotatably connected to the bottom of the buffer plate 16, an output end of the spring damper 19 is rotatably connected to the outer wall of the slider 20, a slide rod 21 is fixedly connected to the outer wall of the slider 20, a compression spring 23 is sleeved on the outer wall of the slide rod 21, a fixed block 22 is slidably connected to the outer wall of the slide rod 21, and the bottom of the fixed block 22 is fixedly connected to the bottom wall inside the foundation 1;

[0028] Specifically, when the weighing plate 2 fails and falls, the buffer plate 16 will immediately play a role and catch the falling weighing plate 2. In addition, the presence of the gasket 15 prevents the weighing plate 2 from directly hitting the buffer plate 16, thereby reducing the possible degree of damage. After catching the falling weighing plate 2, the buffer plate 16 will slide down with the action of gravity. At this time, the buffer plate 16 transmits the force to the slider 20 through the transmission rod 18. The slider 20 slides along the slide rail 17 and further transmits the force to the fixed block 22. The fixed block 22 is tightly fixed on the foundation 1, so that the force The amount can be evenly dispersed on the foundation 1, reducing the pressure on a single point. In the process of the transmission rod 18 transmitting force, the spring damper 19 plays a buffering role, reducing the damage to the system caused by the impact force. When the slider 20 transmits the force to the fixed block 22, the slide bar 21 slides inside the fixed block 22, and the compression spring 23 on the outer wall of the slide bar 21 plays a buffering role, further reducing the impact force during the transmission process. Through this design, the weighing system can effectively protect the safety of equipment and personnel when facing a fault, ensuring the efficient and stable operation of the entire weighing system.

[0029] Working principle: When the foundation 1 is buried underground, the rotating shaft 11 can be driven by the double-headed motor 10, and the rotating shaft 11 can drive the worms 12 on both sides to rotate. The rotation of the worm 12 can drive the worm wheel 13 to rotate, and the transmission shaft 9 inside the foundation 1 will rotate with the worm wheel 13. The rotation of the worm wheel 13 can synchronously drive multiple gears 8 to rotate. Under the rotation of the gear 8, the fixed hook 6 can be driven to move through the rack 7, and the fixed hook 6 will slide out of the annular groove 4 opened inside the foundation 1, so that the fixed hook 6 is inserted into the ground to fix the foundation 1. When the weighing plate 2 fails and falls, the buffer plate 16 will catch the falling The weighing plate 2 is prevented from directly hitting the buffer plate 16 by the gasket 15. After the buffer plate 16 catches the falling weighing plate 2, it will slide down, and the buffer plate 16 will be transmitted to the slider 20 through the transmission rod 18, and then the slider 20 slides on the slide rail 17, so that the force on the slider 20 acts on the fixed block 22, and the fixed block 22 is fixed on the foundation 1, so that the force is dispersed on the foundation 1. During the transmission process of the transmission rod 18, the spring damper 19 is used for buffering, and when the slider 20 transmits the force to the fixed block 22, the slide bar 21 will slide inside the fixed block 22, so that the compression spring 23 on the outer wall of the slide bar 21 is used for buffering.

[0030] 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.
