Description

Technical Field

[0001] This utility model relates to the field of auxiliary tools for metrological verification, and in particular to a support device for weighing instrument verification. Background Technology

[0002] Weighing instruments are tools used to determine the mass of objects using Hooke's Law or the lever balance principle of forces. They calculate the mass of an object by measuring the magnitude of the gravity acting on it. Weighing instruments need to be calibrated during production and use to ensure that they accurately reflect the mass of the object being measured. Through calibration, errors and problems in the weighing instrument can be detected in a timely manner, and adjustments and repairs can be made to ensure the accuracy and stability of the weighing instrument during use.

[0003] In the calibration of weighing instruments, the stability and adaptability of the support device are crucial to ensuring the accuracy of the calibration results. Traditional support devices often suffer from problems such as inconvenient adjustment, poor adaptability, and inability to ensure that the weighing instrument is placed horizontally. Especially in the calibration of weighing instruments of different sizes and weights, traditional support devices often cannot meet diverse needs, causing inconvenience to the calibration work.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] like Figure 1-4 As shown, this utility model provides a support device for weighing instrument calibration, including a top plate 1, a bottom plate 2, a placement support assembly, and a leveling adjustment assembly. A connecting plate 206 is fixedly connected to one side of the bottom of the top plate 1. The bottom plate 2 is located below the top plate 1 and is rotatably connected to the end of the connecting plate 206 away from the top plate 1. The placement support assembly is movably installed on the top plate 1 for supporting and placing weighing instruments of different sizes. The leveling adjustment assembly is located between the bottom plate 2 and the top plate 1 for adjusting the angle of the top plate 1 so that the weighing instrument remains level during the calibration process.

[0026] The support assembly includes a fixed shaft 101 fixedly connected to the top plate 1. A rotating rod 102 is rotatably connected to the fixed shaft 101. One end of the rotating rod 102 is rotatably connected to a first connecting rod 103. One end of the first connecting rod 103 is rotatably connected to a first placement frame 104. The other end of the rotating rod 102 is rotatably connected to a second connecting rod 105. One end of the second connecting rod 105 is rotatably connected to a second placement frame 106. The tops of the second placement frame 106 and the first placement frame 104 are provided with rubber anti-slip pads. When placing the weighing instrument, the anti-slip block at the bottom of the weighing instrument is in contact with the tops of the first placement frame 104 and the second placement frame 106. The first connecting rod 103 and the second connecting rod 105 are respectively connected to the middle of the first placement frame 104 and the second placement frame 106. A groove 109 is provided on the top plate 1, and a distance adjustment threaded rod 110 is rotatably connected in the groove 109. One end of the bottom of the second placement frame 106 is threaded to the distance adjustment threaded rod 110. The end of the distance adjustment threaded rod 110 near the calibration personnel passes through the top plate 1 and is located outside the top plate 1. By turning the distance adjustment threaded rod 110, the second placement frame 106 can be driven to move. At the same time, in coordination with the fixed shaft 101, the rotating rod 102, the first connecting rod 103 and the second connecting rod 105, when the second placement frame 106 moves, it can drive the first placement frame 104 to move synchronously, thereby achieving the purpose of adjusting the distance between the second placement frame 106 and the first placement frame 104, so as to facilitate the support and placement of weighing instruments of different sizes.

[0027] Two sets of mounting grooves 107 are symmetrically arranged on the upper surface of the top plate 1. The bottom center of the second placement frame 106 and the first placement frame 104 are provided with protrusions that are adapted to the mounting grooves 107. A roller 108 is rotatably connected to the bottom center of the protrusion. The roller 108 contacts the bottom of the mounting groove 107, thereby reducing the friction between the first placement frame 104 and the second placement frame 106 and the mounting groove 107 and improving the movement efficiency. The mounting groove 107 is T-shaped. The T-shaped structure can effectively prevent the first placement frame 104 and the second placement frame 106 from detaching from the mounting groove 107.

[0028] The leveling assembly includes an angle-adjusting threaded rod 202, which is rotatably connected to a square groove 201 on the base plate 2. One end of the angle-adjusting threaded rod 202 away from the connecting plate 206 passes through the base plate 2 and is located on the outside of the base plate 2. A threaded block 203 is threadedly connected to the angle-adjusting threaded rod 202, and a support rod 204 is rotatably connected to the threaded block 203. The top end of the support rod 204 is hinged to the lower surface of the top plate 1. The connection between the support rod 204 and the top plate 1 and the threaded block 203 is semi-circular. When the top plate 1 and the base plate 2 are parallel, the threaded block 203 is located in the middle of the square groove 201. A level bubble 205 is fixedly connected to one side of the top plate 1. The level bubble 205 is horizontally set with the top plate 1 and is located on the side closer to the calibration personnel.

[0029] The bottom of the base plate 2 is equipped with a rubber anti-slip block, which can effectively improve the stability of the base plate 2 when placed.

[0030] The first connecting rod 103 and the second connecting rod 105 have the same length and are symmetrically arranged. The first placement frame 104 and the second placement frame 106 are located on both sides of the fixed shaft 101. The size of the bottom plate 2 is the same as that of the top plate 1. The vertical cross-section of the first placement frame 104 and the second placement frame 106 is T-shaped. The upper surface of the first placement frame 104 and the upper surface of the second placement frame 106 are on the same horizontal plane, and the upper surfaces of the first placement frame 104 and the second placement frame 106 are parallel to the upper surface of the top plate 1. Thus, by using the horizontal adjustment component to ensure that the top plate 1 is horizontal, a horizontal and stable support environment can be provided for the weighing instrument.
