Description

Technical Field

[0001] This application relates to the technical field of measuring instruments, and specifically relates to a measuring instrument verification device. Background Art

[0002] Measuring instruments refer to devices, instruments, measuring tools, and reference materials for unifying measurement values that can directly or indirectly measure the measured value of the measured object. They are widely used in various aspects such as production, scientific research, and people's lives, and play a very important role in the entire measurement legislation.

[0003] For example, a measuring instrument verification positioning structure disclosed in a Chinese utility model patent with the publication number "CN219768034U". In this utility model, the device is placed in a suitable position, and then the thumb presses the button to drive the movable rod to move. When the movable rod moves, it drives the movable block to move and stretch the return spring. When the movable block moves, it squeezes two arc-shaped blocks, causing the two arc-shaped blocks to move towards both sides of the installation groove. When the arc-shaped blocks move, they drive the sliders to slide on the slide rods and compress the clamping springs. When the sliders move, they drive the moving plate and the clamping blocks to move. Then, the measuring instrument body is placed on the anti-slip pad on the tray, and then the button is released to make the return spring reset and contract. When the return spring contracts, it drives the movable rod and the movable block to move back to their original positions, so that the movable block is separated from the arc-shaped block. At this time, the two clamping springs stretch and drive the two sliders to move towards each other on the slide rods. When the sliders move, they drive the moving plate and the clamping blocks to move towards the measuring instrument body until the two clamping blocks clamp the measuring instrument body.

[0004] In the above patent, the measuring instrument can be clamped and limited, but after the device limits the measuring instrument and rotates the tray, the measuring instrument will not rotate with the tray. When it is necessary to adjust the angle of the measuring instrument, it needs to be loosened and then the tray is rotated, and the operation is relatively cumbersome and it is difficult to complete the verification work efficiently.

[0020] (III) Beneficial Effects

[0021] This application provides a measuring instrument verification device. The beneficial effects are as follows:

[0022] 1. The measuring instrument verification device is provided with a clamping mechanism, which solves the problem that in the past, the positioning structure for measuring instrument verification caused the tray to rotate after limiting the measuring instrument, but the measuring instrument did not rotate with the tray. When the angle of the measuring instrument needed to be adjusted, it was necessary to loosen it and then rotate the tray, resulting in cumbersome operation and difficulty in efficiently completing the verification work.

During the operation, it was necessary to turn the bolts back and forth, making it difficult to efficiently limit the tray. It achieves the beneficial effect that the angle of the placement tray can be conveniently adjusted and the placement tray can be prevented from rotating after the adjustment is completed, facilitating the use of the device.

[0031] The present application will be further elaborated in detail below with reference to the drawings and embodiments.

[0032] Refer to Figure 1 and Figure 2 In an embodiment of the present application, a measuring instrument verification device is provided, including a base 1. A rotating mechanism 2 for adjusting the angle of the measuring instrument is arranged inside the base 1. A clamping mechanism 3 for limiting the measuring instrument is arranged above the base 1. The clamping mechanism 3 includes a threaded rod 304 and a clamping plate 307. The threaded rod 304 is installed above the base 1, and the clamping plate 307 is installed above the base 1. Through the rotating mechanism 2, the electric telescopic rod 206 can be started. The electric telescopic rod 206 drives the rack 204 to move, so that the rack 204 meshes with the gear 201 to drive the gear 201 to rotate. The connecting rod 202 and the connecting block 203 rotate with the rotation of the gear 201, and then drive the placing plate 301 and the measuring instrument clamped on the placing plate 301 to rotate to adjust the angle of the measuring instrument. Through the clamping mechanism 3, the measuring instrument can be placed on the placing plate 301, the motor 303 is started, the motor 303 drives the first bevel gear 302 to rotate and meshes with the second bevel gear 305 to drive the two second bevel gears 305 and the threaded rod 304 to rotate in opposite directions, and then the two sliders 306 and the clamping plate 307 move in opposite directions to clamp the measuring instrument.

[0033] Refer to Figure 3 and Figure 4 In one aspect of this embodiment, the clamping mechanism 3 includes a placing plate 301. The bottom end of the inner wall of the placing plate 301 is rotatably connected to a first bevel gear 302. One end of the placing plate 301 is fixedly installed with a motor 303, and the output shaft of the motor 303 is fixedly connected to the first bevel gear 302.

[0034] The threaded rod 304 is rotatably connected to both sides of the inner wall of the placing plate 301. One end of the threaded rod 304 is fixedly installed with a second bevel gear 305, and the second bevel gear 305 meshes with the first bevel gear 302.

[0035] The surface of the threaded rod 304 is threadedly connected with a slider 306. The clamping plate 307 is fixedly installed on the upper surface of the slider 306. The slider 306 penetrates through one end of the placing plate 301 and is slidably connected with one end of the placing plate 301. The thread directions of the two threaded rods 304 are the same. By placing the measuring instrument on the placing plate 301 and starting the motor 303, the motor 303 drives the first bevel gear 302 to rotate and engage with the second bevel gear 305, driving the two second bevel gears 305 and the threaded rods 304 to rotate in opposite directions, so that the two sliders 306 and the clamping plates 307 move in opposite directions to clamp the measuring instrument.

[0036] Referring to Figure 1 and Figure 2 In one aspect of this embodiment, a gear 201 is rotatably connected to the bottom end of the inner wall of the base 1. One end of the gear 201 is fixedly installed with a connecting rod 202. One end of the connecting rod 202 is fixedly installed with a connecting block 203.

One side of the fixing plate 205 is fixedly installed with a rack 204. The rack 204 meshes with the gear 201. By starting the electric telescopic rod 206, the electric telescopic rod 206 drives the rack 204 to move, so that the rack 204 meshes with the gear 201 and drives the gear 201 to rotate. The connecting rod 202 and the connecting block 203 rotate with the rotation of the gear 201, thereby driving the placing plate 301 and the measuring instrument clamped on the placing plate 301 to rotate to adjust the angle of the measuring instrument.

[0038] All the electrical equipment in this solution is powered by an external power supply.

[0039] Working principle: When the device is in use, the device should first be placed in a known position, and then the measuring instrument should be placed on the placing plate 301. Start the motor 303. The motor 303 drives the first bevel gear 302 to rotate and engage with the second bevel gear 305, driving the two second bevel gears 305 and the threaded rods 304 to rotate in opposite directions, so that the two sliders 306 and the clamping plates 307 move in opposite directions to clamp the measuring instrument. Then the verification work can be carried out. When it is necessary to adjust the angle of the measuring instrument, start the electric telescopic rod 206. The electric telescopic rod 206 drives the rack 204 to move, so that the rack 204 meshes with the gear 201 and drives the gear 201 to rotate. The connecting rod 202 and the connecting block 203 rotate with the rotation of the gear 201, thereby driving the placing plate 301 and the measuring instrument clamped on the placing plate 301 to rotate to adjust the angle of the measuring instrument.
