Technical Field

[0001] The utility model application relates to the technical field of weighing sensors, in particular to a stable column-type weighing sensor structure. Background Art

[0002] A weighing sensor is actually a device that converts mass signals into measurable electrical signal outputs. When using a sensor, the actual working environment of the sensor should be considered first. This is crucial to the correct selection of a weighing sensor. It is related to whether the sensor can work properly, its safety and service life, and even the reliability and safety of the entire weighing instrument. There are qualitative differences between the old and new national standards in the basic concepts and evaluation methods of the main technical indicators of weighing sensors. There are mainly several styles, such as S-type, cantilever type, spoke type, plate ring type, diaphragm box type, bridge type, column type, etc.

[0003] When a traditional column weighing sensor measures the weight of an object, due to its cylindrical structure with the same upper and lower radii, the stability of the bottom of this column weighing sensor is poor during use and it is easily affected by external factors, resulting in deviations in the measurement results. In order to improve the stability and measurement accuracy of the column weighing sensor, the present invention proposes a stable column weighing sensor structure. Summary of the invention

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Furthermore, a top seat ring is threadedly connected to the upper outer side of the sensor body, four fixed blocks are fixed to the outer side of the top seat ring, each of the fixed blocks is slidably sleeved with a connecting column, a top support plate is fixed to the top surface of the four connecting columns, each of the connecting columns is sleeved with a spring, the top surface of the spring is fixedly connected to the bottom surface of the top support plate, and the bottom surface of the spring is fixedly connected to the top surface of the fixed block.

[0008] Furthermore, the bottom support plate is in an arc shape, and the inner circle radius of the bottom support plate is the same as the outer circle radius of the base ring.

[0009] Furthermore, a non-slip rubber having the same shape as the bottom supporting plate is fixed to the bottom end of each bottom supporting plate, and the bottom surface of the non-slip rubber is flush with the bottom surface of the sensor body.

[0010] Furthermore, a rubber pad having the same shape as the top supporting plate is fixed to the top surface of the top supporting plate, and the top surface of the rubber pad is located above the top surface of the sensing plate.

[0011] Furthermore, the top surface and the bottom surface of the sliding block are flush with the top surface and the bottom surface of the sliding groove, and the top surface and the bottom surface of the sliding block are both provided with anti-slip stripes.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, a base ring is arranged below the outer side of the sensor body, and slide grooves are provided around the outer side of the base ring. Then, the slider is pulled out from the inside of the slide groove, so that when the bottom end of the sensor body contacts the ground, the bottom support plate also contacts the ground at the same time, so that the bottom support plate supports the bottom end of the sensor body.

[0021] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A stable column weighing sensor structure includes a sensor body 1 and a sensing plate 2. The sensing plate 2 is arranged on the top surface of the sensor body 1. A base ring 3 is threadedly connected to the lower outer side of the sensor body 1. Four slide grooves 4 are fixed to the outer side of the base ring 3. A limit plate 5 is fixed on the end of each slide groove 4 away from the sensor body 1. A limit block 7 is slidably connected inside the slide groove 4. A slider 6 is slidably connected inside the slide groove 4. A limit block 7 is fixed on the end of the slider 6 close to the sensor body 1. Bottom support plates 8 are fixed on both sides of the slider 6, so that the bottom surface of the sensor body 1 is more stable.

[0023] Specifically, the bottom support plate 8 is in an arc shape, and the inner circle radius of the bottom support plate 8 is the same as the outer circle radius of the base ring 3, which is convenient for storing the bottom support plate 8. The bottom end of each bottom support plate 8 is fixed with an anti-slip rubber 9 of the same shape as the bottom support plate 8. The bottom surface of the anti-slip rubber 9 is flush with the bottom surface of the sensor body 1, so that the anti-slip rubber 9 improves the stability of the bottom surface of the sensor body 1. The top and bottom surfaces of the slider 6 are flush with the top and bottom surfaces of the slide groove 4. The top and bottom surfaces of the slider 6 are both provided with anti-slip stripes, which is convenient for the staff to pull out the slider 6.

[0024] As an optimization solution, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a top seat ring 10 is threadedly connected to the upper outer side of the sensor body 1, and four fixed blocks 11 are fixed to the outer side of the top seat ring 10. A connecting column 12 is slidably sleeved on each of the fixed blocks 11, and a top support plate 14 is fixed to the top surface of the four connecting columns 12. A spring 13 is sleeved on each of the connecting columns 12, and the top surface of the spring 13 is fixedly connected to the bottom surface of the top support plate 14, and the bottom surface of the spring 13 is fixedly connected to the top surface of the fixed block 11, so that when the sensing plate 2 weighs the object, the top support plate 14 makes the object more stable.

[0025] Specifically, a rubber pad 15 having the same shape as the top support plate 14 is fixed to the top surface of the top support plate 14 , and the top surface of the rubber pad 15 is located above the top surface of the sensing plate 2 , further improving the stability of the items when placed.

[0026] Working principle: When the sensor body 1 needs to be weighed, the base ring 3 is threadedly fixed at the lower side of the sensor body 1, and then the slider 6 is pulled out from the inside of the slide groove 4. The movement of the slider 6 drives the limit block 7 to move, and at the same time, the limit plate 5 limits the limit block 7 to prevent the slider 6 from being pulled out of the slide groove 4. When the slider 6 moves, it drives the bottom support plate 8 to move, and at the same time, the bottom support plate 8 drives the anti-slip rubber 9 to move, so that the bottom support plate 8 is expanded, so that the contact area between the bottom end of the sensor body 1 and the ground is increased, so that the bottom end of the sensor body 1 The top seat ring 10 is threadedly fixed on the upper side of the sensor body 1. When an object is placed on the top surface of the sensing plate 2 for weighing, the object presses down the rubber pad 15 at the same time, so that the rubber pad 15 drives the top support plate 14 to move downward, and at the same time, the top support plate 14 drives the connecting column 12 to move downward, so that the connecting column 12 slides inside the fixed block 11. At this time, the spring 13 is compressed and accumulates force, and the top support plate 14 increases the contact area between the top surface of the sensor body 1 and the object, and at the same time, the rubber pad 15 fixes the object on the top surface of the sensing plate 2.
