Description

Technical Field

[0001] This utility model relates to the field of weighing sensor technology, and in particular to an overload protection device for the elastic element inside a weighing sensor. Background Technology

[0002] As a core component for accurately measuring the weight of objects, load cells are widely used in many fields such as industrial production, commerce, transportation, and medical equipment. In these applications, the performance and reliability of load cells are crucial, as their measurement accuracy directly affects the precise control of production processes, the fairness of transactions, the safe operation of equipment, and the accuracy of medical diagnoses.

[0003] Currently, one type of overload protection device for the elastic element inside a weighing sensor has a complex internal overload protection mechanism, making operation cumbersome, replacement and manufacturing costs high, resulting in significant limitations and poor practicality. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of existing technologies where the internal overload protection mechanism has many structures, is very cumbersome to operate, has high replacement and manufacturing costs, has great limitations, and has poor practicality. Therefore, this utility model proposes an overload protection device for the elastic element inside the weighing sensor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an overload protection device for an elastic element inside a weighing sensor, comprising an end head, one end of which is fixed with an elastic element body, both ends of the inner bottom wall of the elastic element body are provided with support plates, and two matching triangular sliders are provided between the two support plates, the two triangular sliders being fixed together by adjusting screws.

[0006] Preferably, protrusions are fixed on both sides of the opposite ends of the two support plates, and slots matching the protrusions are opened at both ends of the inner wall of the elastic element body.

[0007] Preferably, the protrusion is snapped into place within the slot.

[0008] Preferably, the opposite ends of the two triangular sliders abut against the two support plates respectively.

[0009] Preferably, the end has two first mounting holes, and the elastic element body has multiple connecting holes.

[0010] Preferably, each of the two triangular sliders has a second mounting hole that matches the adjusting screw.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, adjusting the adjusting screw drives two triangular sliders to move, causing them to tighten the support plate. This tightening action provides stable support for the support plate. The two support plates, which are vertically aligned, precisely support the four weak points of the slots through four protrusions. Under pressure, the support plate will not easily deform due to the tightening of the triangular sliders. Furthermore, the synergistic effect of the upper and lower support plates ensures that the entire surface remains flat under pressure. The adjusting screw is the key power adjustment component; its rotation changes the position of the triangular sliders, thereby adjusting the tightness of the support plate. The triangular sliders play a role in force transmission and dispersion, converting the rotational force of the adjusting screw into a uniform tightening force on the support plate. The vertically aligned support plates directly... Acting on weak points, it works together to maintain the flatness of the entire surface under pressure, enhancing structural stability. Under pressure, it ensures reliable support for weak points, preventing structural deformation or damage due to uneven local stress, thus improving safety. In practical applications, such as temporary support structures in building construction, this device, ensuring the flatness of the pressure-bearing surface, can prevent safety accidents caused by uneven support surfaces, improving safety and product quality. In fields with high flatness requirements, such as machining, using this device can guarantee the flatness of the processed surface, thereby improving product quality and reducing maintenance costs. Because this device reduces malfunctions caused by structural deformation or unevenness, it further reduces equipment or structural maintenance costs, making it more practical.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1, such as Figure 1-3 As shown, this utility model provides an overload protection device for the elastic element inside a weighing sensor, including an end 1, an elastic element body 9 fixed at one end of the end 1, support plates 5 at both ends of the inner bottom wall of the elastic element body 9, and two matching triangular sliders 3 between the two support plates 5, which are fixed together by adjusting screws 4.

[0020] The overall effect of Embodiment 1 is that, under pressure, the support plate 5 will not easily deform due to the tightening of the triangular slider 3, and the synergistic effect of the upper and lower support plates 5 ensures that the entire surface remains flat under pressure. The adjusting screw 4 is a key power adjustment component; its rotation changes the position of the triangular slider 3, thereby adjusting the tightness of the support plate 5. The triangular slider 3 plays a role in force transmission and dispersion, converting the rotational force of the adjusting screw 4 into a uniform tightening force on the support plate 5. The upper and lower support plates 5, which are in close contact, directly act on the weak points, jointly maintaining the flatness of the entire surface under pressure, enhancing structural stability, and providing support under load. Under pressure, it ensures reliable support for weak points in the structure, preventing deformation or damage due to uneven local stress, thus improving safety. In practical applications, such as temporary support structures in building construction, this device, which ensures the flatness of the pressure-bearing surface, can prevent safety accidents caused by uneven support surfaces, improving safety and product quality. In fields with high flatness requirements, such as machining, this device can guarantee the flatness of the processed surface, thereby improving product quality and reducing maintenance costs. Because this device can reduce failures caused by structural deformation or unevenness, it further reduces the maintenance costs of equipment or structures, making it more practical.

[0021] Example 2, as Figure 1-3 As shown, protrusions 6 are fixed on both sides of the opposite ends of the two support plates 5. The inner walls of the elastic element body 9 are provided with slots 7 that match the protrusions 6 at both ends. The protrusions 6 are snapped into the slots 7. The opposite ends of the two triangular sliders 3 abut against the two support plates 5 respectively. Two first mounting holes 2 are provided in the end 1. Multiple connecting holes 8 are provided in the elastic element body 9. The two triangular sliders 3 are provided with second mounting holes 10 that match the adjusting screws 4.

[0022] The effect achieved by the entire embodiment 2 is that by adjusting the adjusting screw 4, the two triangular sliders 3 are driven to move, so that they press the support plate 5 tightly. This pressing action provides stable support force for the support plate 5. The two support plates 5, which are closely fitted at the top and bottom, accurately support the weak points of the four slots 7 through the four protrusions 6. When under pressure, they work together to maintain the flatness of the entire surface, enhance the structural stability, and ensure that the weak points of the structure are reliably supported when under pressure, so as to avoid structural deformation or damage due to uneven local stress, and improve the safety of use.

[0023] Working Principle: When in use, adjusting the adjusting screw 4 drives the two triangular sliders 3 to move, causing them to press against the support plate 5. This pressing action provides stable support for the support plate 5. The two support plates 5, with their upper and lower parts in close contact, precisely support the weak points of the four slots 7 through four protrusions 6. Under pressure, due to the pressing of the triangular sliders 3, the support plate 5 will not easily deform. Furthermore, the synergistic effect of the upper and lower support plates 5 ensures that the entire surface remains flat under pressure. The adjusting screw 4 is the key power adjustment component; its rotation changes the position of the triangular sliders 3, thereby adjusting the degree of pressing against the support plate 5. The triangular sliders 3 play a role in force transmission and dispersion, converting the rotational force of the adjusting screw 4 into a uniform pressing force on the support plate 5. The lower supporting plate 5 directly acts on the weak point, working together to maintain the flatness of the entire surface under pressure, enhancing structural stability. Under pressure, it ensures reliable support for the weak point, preventing structural deformation or damage due to uneven local stress, thus improving safety. In practical applications, such as temporary support structures in building construction, this device, which ensures the flatness of the pressure surface, can prevent safety accidents caused by uneven support surfaces, improving safety and product quality. In fields with high flatness requirements, such as machining, this device can guarantee the flatness of the processed surface, thereby improving product quality and reducing maintenance costs. Because this device reduces malfunctions caused by structural deformation or unevenness, it further reduces equipment or structural maintenance costs, making it more practical.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
