Description

Technical Field

[0001] This application relates to the field of electronic scale technology, and in particular to an elastic force transmission beam for electronic scales. Background Technology

[0002] An electronic scale is a type of weighing instrument. Weighing instruments are tools that use Hooke's Law or the lever balance principle of forces to determine the mass of an object. According to their structural principles, they can be divided into three main categories: mechanical scales, electronic scales, and electromechanical scales. Electronic scales mainly consist of three parts: a load-bearing system, a force transmission and conversion system, and a display system.

[0003] When electronic scales are in use, force needs to be transmitted through an elastic force transmission beam. However, ordinary elastic force transmission beams have a fixed structure and can only meet a fixed weighing range, which cannot be adapted to different models of electronic scales. Therefore, we propose an elastic force transmission beam for electronic scales. Utility Model Content

[0004] This application provides an elastic force transmission beam for electronic scales to solve the problems mentioned above.

[0005] This application provides an elastic force transmission beam for electronic scales, comprising:

[0006] The elastic force transmission beam body has an arc groove in the middle of its lower end, and elastic blocks are fixedly connected to the left and right sides inside the arc groove. A limiting rectangular opening is opened in the middle of the opposite face of the elastic block, and a reinforcing block is movably inserted inside the limiting rectangular opening.

[0007] The upper end of the inner cavity of the arc groove is connected to a connecting plate, and the lower middle part of the connecting plate is connected to an adjusting screw structure through a bearing.

[0008] The adjusting screw structure has a first threaded section and a second threaded section on its left and right sides, respectively. The first threaded section and the second threaded section have opposite thread directions, and both the first threaded section and the second threaded section are threadedly inserted into the middle of the reinforcing block.

[0009] An adjusting spring is fixedly mounted on the surface of the reinforcing block away from the middle of the adjusting screw structure.

[0010] Preferably, the middle left side of the adjusting screw structure is further provided with a third threaded section, the outer side of which is fitted with a first nut, and the outer middle right side of the adjusting screw structure is fixedly fitted with a second nut.

[0011] Preferably, the first nut and the second nut are respectively disposed on the left and right sides of the connecting plate.

[0012] Preferably, stabilizing plates are fixedly connected to the lower left and right sides of the elastic force transmission beam body, and the stabilizing plates extend to the middle of the lower end of the corresponding elastic blocks.

[0013] Preferably, mounting bases are fixedly connected to the lower right side of the stabilizing plates on the upper left and right sides of the elastic force transmission beam body.

[0014] Preferably, the front and rear end faces of the reinforcing block are in contact with the front and rear sidewalls of the limiting rectangular opening, and the height of the reinforcing block is less than the height of the limiting rectangular opening.

[0015] Preferably, the elastic block is a rubber elastic block.

[0016] The technical solutions provided in this application have the following advantages compared with the prior art:

[0017] The structure provided in this application embodiment allows the second nut to be turned in both directions by a tool, thereby driving the screw of the adjusting screw structure to rotate in both directions. This causes the two reinforcing blocks to shift relative to or opposite to each other, which in turn allows the adjusting spring to be compressed or released, thereby changing the elastic strength of the elastic block and increasing the elastic strength of the elastic transmission beam body. After the position of the reinforcing block is adjusted, the first nut is turned, causing the first nut to press and tighten the connecting plate, thus positioning the adjusting screw structure. This prevents the adjusting screw structure from rotating due to external vibrations during use, thereby meeting the needs of different models of electronic scales, i.e., changing the weighing range of the electronic scale.

In this application, "and / or" describes the relationship between related objects, indicating that three relationships may exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. A and B can be singular or plural. In this application, "at least one" means one or more, and "more than one" means two or more. "At least one," "at least one of the following," or similar expressions refer to any combination of these items, including any combination of a single item or a plural item.

[0027] like Figures 1-3 As shown, this application embodiment provides an elastic force transmission beam for electronic scales, comprising:

[0028] The elastic force transmission beam body 1 has an arc groove 3 in the middle of the lower end of the elastic force transmission beam body 1, and elastic blocks 5 are fixedly connected to the left and right sides inside the arc groove 3. A limiting rectangular opening 8 is opened in the middle of the opposite surface of the elastic block 5, and a reinforcing block 9 is movably inserted inside the limiting rectangular opening 8.

[0029] The upper end of the inner cavity of the arc groove 3 is connected to a connecting plate 6, and the lower middle part of the connecting plate 6 is connected to an adjusting screw structure 7 by means of a bearing.

[0030] The adjusting screw structure 7 has a first threaded section 71 and a second threaded section 75 on its left and right sides, respectively. The threaded directions of the first threaded section 71 and the second threaded section 75 are opposite, and both the first threaded section 71 and the second threaded section 75 are threadedly inserted into the middle of the reinforcing block 9.

[0031] An adjusting spring 10 is fixedly mounted on the surface of the reinforcing block 9 away from the middle of the adjusting screw structure 7.

[0032] like Figure 3 As shown, the middle left side of the adjusting screw structure 7 is also provided with a third threaded section 72, the outer side of the third threaded section 72 is sleeved with a first nut 74, and the outer middle right side of the adjusting screw structure 7 is fixedly sleeved with a second nut 73.

[0033] The first nut 74 and the second nut 73 are respectively disposed on the left and right sides of the connecting plate 6.

[0034] Specifically: the second nut 73 drives the adjusting screw structure 7 to rotate through an external tool; the first nut 74 locks the position of the adjusting screw structure 7 by turning it with an external tool.

[0035] like Figure 1 As shown, the lower left and right sides of the elastic force transmission beam body 1 are fixedly connected to stabilizing plates 4, and the stabilizing plates 4 extend to the lower middle of the corresponding elastic blocks 5.

[0036] Specifically: the stabilizing plate 4 can increase the connection strength of the elastic block 5.

[0037] like Figure 1 As shown, mounting bases 2 are fixedly connected to the upper left and right sides of the stabilizing plates 4 and the lower right side of the elastic force transmission beam body 1.

[0038] Specifically: Mounting base 2 is a mounting structure that can be fixed with bolts or adhesive.

[0039] like Figure 2As shown, the front and rear end faces of the reinforcing block 9 are in contact with the front and rear side walls of the limiting rectangular opening 8, and the height of the reinforcing block 9 is less than the height of the limiting rectangular opening 8.

[0040] Specifically: the reinforcing block 9 can move inside the limiting rectangular opening 8, thereby squeezing or releasing the adjusting spring 10.

[0041] like Figure 1 As shown, the elastic block 5 is specifically a rubber elastic block.

[0042] Principle: When the equipment is in use, the mounting base 2 of the elastic force transmission beam body 1 is connected between the electronic scale base and the upper end plate;

[0043] The elastic force transmission beam body 1 is a general-purpose force transmission beam, which can meet the application range of different models of electronic scales.

[0044] When adjusting its range, loosen the first nut 74, and then use a tool to turn the second nut 73 forward and backward, thereby driving the screw of the adjusting screw structure 7 to rotate forward and backward, causing the two reinforcing blocks 9 to move relative to or opposite to each other, thereby pressing or releasing the adjusting spring 10, thus changing the elastic strength of the elastic block 5 and increasing the elastic strength of the elastic transmission beam body 1. After the position of the reinforcing block 9 is adjusted, tighten the first nut 74, so that the first nut 74 presses and tightens the connecting plate 6, thereby positioning the position of the adjusting screw structure 7, so that the adjusting screw structure 7 will not rotate due to external vibration during the use of the equipment, thus meeting the needs of different models of electronic scales, that is, changing the weighing range of the electronic scale, with a range of 0kg-100kg.

[0045] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed in this application.
