DETAILED DESCRIPTION

[0025] The technical schemes in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without any creative effort belong to the protection scope of the present application.

[0026] The purpose of the present application is to provide a double-layer buffer structure of a scale body to solve the problems in the prior art, which is simple in structure and effectively improves the buffer effect of the scale body.

[0027] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in combination with the drawings and specific embodiments.

[0028] The present application provides a double-layer buffer structure of a scale body, as shown in Figs. 1-5As shown, the system includes: a weighing base, multiple weighing sensors 7, multiple support plates 4, multiple limiting posts 5, multiple inner springs 3, multiple outer springs 2, and a weighing platform 1. The weighing base is detachably and fixedly connected to the working surface. Each weighing sensor 7 is mounted on the weighing base. A support plate 4 is mounted on the top of a weighing sensor 7. The bottom end of a limiting post 5 is fixedly connected to a support plate 4. An inner spring 3 is sleeved on the outside of a limiting post 5, and the bottom of the inner spring 3 is fixedly connected to the support plate 4. An outer spring 2 is sleeved on the outside of an inner spring 3, and the bottom of the outer spring 2 is fixedly connected to the support plate 4. The inner spring 3 rotates in the opposite direction to the outer spring 2. The bottom of the weighing platform 1 is equipped with multiple spring mounting slots and multiple sliding grooves. One spring mounting slot is located below one sliding groove, and the top of the limiting post 5 extends into the sliding groove and can slide within it. The tops of both the inner spring 3 and the outer spring 2 are fixedly connected to the spring mounting slots. This structural design creates a double-layer buffer system. The outer spring 2 and the inner spring 3 rotate in opposite directions and are arranged in layers. When the weighing platform 1 is impacted by a heavy object, the two layers of springs work together. First, the outer spring 2 absorbs a portion of the impact force and deforms, and then the inner spring 3 further absorbs the remaining impact energy and deforms, achieving efficient absorption and dispersion of the impact force. The limiting post 5, in conjunction with the sliding groove, not only prevents the weighing platform 1 from colliding with the load-bearing base 8 due to excessive descent, but also ensures the stability of the weighing platform 1 during descent and rebound, avoiding deviation that could affect weighing accuracy and damage components. This effectively extends the service life of all components of the scale and reduces the probability of component damage.

[0029] In a preferred embodiment, a receiving slot is provided on both sides of the weighing base. The receiving slot is used to install each weighing sensor 7 and each support plate 4. The receiving slot provides dedicated installation space for the weighing sensors 7 and support plates 4, making the installation of these components more orderly and systematic. On the one hand, this facilitates the assembly of the scale structure, allowing workers to more easily install the components in their designated positions; on the other hand, it helps protect the weighing sensors 7 and support plates 4 from direct impact and damage in the external environment, improving the stability and reliability of the entire scale structure.

[0030] In a preferred embodiment, the number of load cells 7, support plate 4, limiting post 5, inner spring 3, and outer spring 2 are all 24, and they are evenly distributed in the two receiving slots. The determined number and even distribution of each component ensure that the scale body experiences uniform force on all parts when bearing heavy objects. This avoids structural deformation and damage due to excessive localized force, improving weighing accuracy and ensuring the accuracy of weighing data. Simultaneously, the even distribution allows the double-layer buffer structure to provide good cushioning at all locations when the scale body is subjected to impact, enhancing the overall buffering protection capability.

[0031] In a preferred scheme of the embodiment, the double-layer buffer structure of the scale body further comprises a plurality of partition plates 16, which are arranged between two adjacent load sensors 7 and have a height higher than that of the accommodating groove. The partition plates 16 can effectively separate the adjacent load sensors 7 and prevent them from affecting each other during operation, such as signal interference caused by vibration. The design of the height higher than that of the accommodating groove can prevent other sundries from entering the accommodating groove and damaging the sensors, and to some extent, can also enhance the structural rigidity, making the scale body structure more stable.

[0032] In a preferred scheme of the embodiment, the double-layer buffer structure of the scale body further comprises a plurality of inner bolts 6, which connect the support plates 4 and the load sensors 7. This connection mode can ensure effective force transmission between the support plates 4 and the load sensors 7, and ensure accurate acquisition of the weighing data.

[0033] In a preferred scheme of the embodiment, the double-layer buffer structure of the scale body further comprises four anti-falling leaves 10, the bottom end of each anti-falling leaf 10 is fixedly connected to the weighing base, the top of one anti-falling leaf 10 is slidably connected to the side wall of one corner of the bottom of the weighing table 1, and the four anti-falling leaves 10 form an anti-falling position. The weighing table 1 is slidably connected in the anti-falling position, and the anti-falling position formed by the anti-falling leaves 10 can effectively prevent the weighing table 1 from sliding outward due to the loss of support when the scale body structure is accidentally damaged. This not only ensures the safety of the weighing table 1, but also avoids damage to surrounding personnel and equipment caused by the sliding of the weighing table 1, greatly improving the safety of the entire scale body structure during use.

[0034] In a preferred scheme of the embodiment, the height of the anti-falling leaf 10 is less than the height of the outer spring 2. The height of the anti-falling leaf 10 is less than the height of the outer spring 2, which ensures that the buffering effect of the outer spring 2 is not disturbed by the anti-falling leaf 10 during normal use, and the outer spring 2 can fully exert its buffering performance. At the same time, when the spring is deformed during normal operation, the anti-falling leaf 10 will not hinder the normal descent and rebound of the weighing table 1 due to its excessive height, ensuring the normal operation of the scale body buffer function.

[0035] In a preferred scheme of the embodiment, the double-layer buffer structure of the scale body further comprises a plurality of top bolts 11 and a top rubber pad 12, which is fixedly connected to the top surface of the weighing table 1 for contacting the measured object by the top bolts 11. The top rubber pad 12 protects the top of the weighing table 1 during material receiving, and can buffer the impact force of the material on the surface of the weighing table 1 when the weight is placed on the weighing table 1, preventing the top surface of the weighing table 1 from being damaged due to long-term impact of the material, prolonging the service life of the weighing table 1, and ensuring the flatness of the surface of the weighing table 1, which is conducive to improving the accuracy of weighing.

[0036] In one preferred scheme of the embodiment, the scale body double-layer buffer structure further comprises four motors 13, four limiting rotating blocks 14 and four bottom bolts 15, the bottom of each corner of the weighing base is provided with a limiting groove, the shell of the motor 13 is fixedly connected with the weighing base, the output shaft of the motor 13 extends into the limiting groove and is fixedly connected with the limiting rotating block 14, the limiting rotating block 14 can be driven by the motor 13 to rotate out of or into the limiting groove, the limiting rotating block 14 is arranged in the mounting hole, after the limiting rotating block 14 rotates out of the limiting groove, the bottom bolt 15 is used for penetrating through the mounting hole and being fixedly connected with the working surface, which realizes flexible locking and unlocking of the scale body structure in the working position.

[0037] In one preferred scheme of the embodiment, the scale body double-layer buffer structure further comprises a plurality of movable connecting pins 9, each movable connecting pin 9 is uniformly arranged on the two sides of the bearing base 8, and the design of the movable connecting pin 9 facilitates the overall movement of the scale body structure.

[0038] The principles and implementation modes of the specific examples in the utility model are described, and the above embodiment is only used to help understand the method and core idea of the utility model; meanwhile, for the general technical personnel in the field, the specific implementation mode and application range will be changed according to the idea of the utility model.
