Description

Technical Field

[0001] This utility model relates to the field of measurement technology, and in particular to a balance weighing and testing device. Background Technology

[0002] A balance is a weighing instrument consisting of a beam supported by a fulcrum (axis) at its center, forming two arms. Each arm has a pan, one pan holding an object of known mass and the other holding the object to be measured. The deflection of a pointer fixed to the beam when it is not swinging and points to the center mark indicates the mass of the object being measured. In many fields, such as scientific research, industrial production, and quality control, the accuracy of measurement is crucial to the accuracy and reliability of the results. Therefore, a balance weighing and testing device is needed.

[0003] Regarding existing related technologies, the inventors believe that the following defects often exist: existing balance weighing and testing devices usually rely on manual operation for leveling, such as using tools like spirit levels and bubble levels for manual adjustment. The operation is cumbersome, resulting in low leveling efficiency and thus reducing the efficiency of the equipment. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing balance weighing and testing devices have the disadvantages of being cumbersome to operate and inefficient during leveling. Therefore, we propose a balance weighing and testing device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a balance weighing and testing device, comprising a base, support rods fixed on both sides of the top of the base, a balance beam rotatably connected to the opposing surfaces of the support rods via a rotating shaft, weight pans provided at both ends of the balance beam, a scale plate fixed on the top of the base, a pointer rotatably connected to one side of the scale plate via a rotating shaft, fixing blocks fixed at both ends of the bottom of the balance beam, a sleeve fixed at the bottom of the balance beam, a leveling rod slidably connected to both ends inside the sleeve, an adjustment groove provided at the bottom of the leveling rod, a leveling block slidably connected inside the adjustment groove, a sliding rod slidably connected inside the leveling block, a circular plate fixed at the bottom of the sliding rod, a first spring slidably connected to the surface of the sliding rod, one end of the first spring fixed to the leveling block, and the other end of the first spring fixed to the circular plate.

[0006] Preferably, a first sliding groove is provided on both sides of the inside of the adjusting groove, and the inside of the first sliding groove is slidably connected to the leveling block.

[0007] Preferably, a rubber pad is fixed inside the adjusting groove, and the rubber pad abuts against the top of the slide rod.

[0008] Preferably, the bottom of the sleeve is provided with a storage groove, and a second spring is fixed inside the storage groove. The other end of the second spring is fixed to the leveling rod.

[0009] Preferably, both ends of the leveling rod are provided with placement grooves, and push blocks are slidably connected inside the placement grooves. Both ends of the fixing block are provided with through holes, and the inside of the through holes is slidably connected to the push blocks.

[0010] Preferably, a third spring is fixedly connected inside the placement slot, and the other end of the third spring is fixed to the push block.

[0011] Preferably, a second sliding groove is provided on both sides inside the placement groove, and a slider is slidably connected inside the second sliding groove, with one end of the slider fixed to the push block.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by pulling the circular plate, the sliding rod moves towards the circular plate, and then the leveling block slides left and right inside the adjustment groove, thereby leveling and calibrating the balance beam, ensuring that the equipment can maintain a horizontal state, thus obtaining more accurate measurement results. The operation is simple, saves manual adjustment time, and improves efficiency.

[0014] In this invention, by pressing the push block, the push block is moved into the placement groove, while the third spring is squeezed until the push block moves into the placement groove, releasing the fixation of the leveling rod, which can then be stored. When the equipment needs to be leveled, the leveling rod is pulled into the fixed block, and the rebound force of the third spring pushes the push block into the through hole, thus facilitating the fixation of the leveling rod and making it convenient for the user to perform leveling operations.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0024] Reference Figures 1-7 As shown, this utility model provides a technical solution: a balance weighing and testing device, including a base 1, with support rods 2 fixed on both sides of the top of the base 1, and a balance beam 3 rotatably connected to the opposing surfaces of the support rods 2 via a rotating shaft. Weight pans 4 are provided at both ends of the balance beam 3. A scale plate 5 is fixed to the top of the base 1, and a pointer 6 is rotatably connected to one side of the scale plate 5 via a rotating shaft. Fixing blocks 7 are fixed to both ends of the bottom of the balance beam 3, and a sleeve 8 is fixed to the bottom of the balance beam 3. A leveling rod 9 is slidably connected to both ends inside the sleeve 8, and an adjustment groove 11 is provided at the bottom of the leveling rod 9. An adjustment mechanism is slidably connected inside the adjustment groove 11. The leveling block 12 has a sliding rod 13 internally connected to it. A circular plate 14 is fixed to the bottom of the sliding rod 13. A first spring 15 is slidably connected to the surface of the sliding rod 13. One end of the first spring 15 is fixed to the leveling block 12, and the other end of the first spring 15 is fixed to the circular plate 14. By pulling the circular plate 14, the sliding rod 13 moves towards the circular plate 14. Then, the leveling block 12 slides left and right inside the adjustment groove 11, thereby leveling and calibrating the balance beam 3 to ensure that the equipment can maintain a horizontal state, thus obtaining more accurate measurement results. The operation is simple, saves manual adjustment time, and improves efficiency.

[0025] Reference Figures 1-3 As shown in this embodiment: both sides of the adjustment groove 11 are provided with first sliding grooves 16. The interior of the first sliding groove 16 is slidably connected to the leveling block 12. By setting the first sliding groove 16, the horizontal movement of the leveling block 12 can be ensured, avoiding deviation and affecting its accuracy.

[0026] Reference Figures 1-3 As shown in this embodiment: a rubber pad 17 is fixed inside the adjusting groove 11. The rubber pad 17 abuts against the top of the slide rod 13. By setting the rubber pad 17, the friction between the top of the slide rod 13 and the inside of the adjusting groove 11 can be increased.

[0027] Reference Figure 1 , Figure 4 and Figure 5 As shown in this embodiment: a storage groove 18 is provided at the bottom of the sleeve 8, and a second spring 19 is fixed inside the storage groove 18. The other end of the second spring 19 is fixed to the leveling rod 9. By setting the storage groove 18, it is convenient to adjust the length of the leveling rod 9. By setting the second spring 19, it is prevented that the user will use too much force when adjusting the leveling rod 9, causing the leveling rod 9 to fall out of the storage groove 18.

[0028] Reference Figure 1 , Figure 6 and Figure 7 As shown in this embodiment: both ends of the leveling rod 9 are provided with placement grooves 20, and push blocks 21 are slidably connected inside the placement grooves 20. Both ends of the fixing block 7 are provided with through holes 22, and the inside of the through holes 22 is slidably connected to the push blocks 21. A third spring 23 is fixedly connected inside the placement grooves 20, and the other end of the third spring 23 is fixed to the push blocks 21. By pressing the push blocks 21, the push blocks 21 are moved into the placement grooves 20, and the third spring 23 is squeezed until the push blocks 21 move into the placement grooves 20, releasing the fixation of the leveling rod 9. The leveling rod 9 can then be stored. When it is necessary to level the equipment, the leveling rod 9 is pulled into the fixing block 7, and the rebound force of the third spring 23 is used to push the push blocks 21 into the through holes 22, thereby facilitating the fixation of the leveling rod 9 and making it convenient for the user to perform leveling operations.

[0029] Reference Figure 1 , Figure 6 and Figure 7 As shown in this embodiment: a second sliding groove 24 is provided on both sides inside the placement groove 20. A slider 25 is slidably connected inside the second sliding groove 24. One end of the slider 25 is fixed to the push block 21. By setting the structure of the second sliding groove 24 and the slider 25, the movement direction of the push block 21 can be restricted to avoid tilting.

[0030] Working principle: The user pulls the circular plate 14 to move the sliding rod 13 towards the circular plate 14, and then uses the leveling block 12 to slide left and right inside the adjusting groove 11, thereby leveling and calibrating the balance beam 3, ensuring that the equipment can maintain a horizontal state, thus obtaining more accurate measurement results. The operation is simple, saves manual adjustment time, and improves efficiency. By setting the first sliding groove 16, the horizontal movement of the leveling block 12 can be ensured, avoiding deviation and affecting its accuracy. By setting the rubber pad 17, the friction between the top of the sliding rod 13 and the inside of the adjusting groove 11 can be increased. By setting the storage groove 18, the length of the leveling rod 9 can be easily adjusted. By setting the second spring 19, it is possible to prevent... If the user applies excessive force when adjusting the leveling rod 9, causing it to disengage from the storage slot 18, pressing the push block 21 will move it into the placement slot 20, simultaneously compressing the third spring 23 until the push block 21 moves into the placement slot 20, releasing the fixation of the leveling rod 9 and allowing it to be stored. When the equipment needs to be leveled, the leveling rod 9 is pulled into the fixing block 7, and the rebound force of the third spring 23 pushes the push block 21 into the through hole 22, thus facilitating the fixation of the leveling rod 9 and making it convenient for the user to perform leveling operations. The structure of the second slide 24 and the slider 25 restricts the movement direction of the push block 21, preventing tilting.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
