[0019] Compared with the related art, the measuring instrument for intelligent instrument manufacturing provided by the utility model has the following beneficial effects:

[0020] The utility model provides a measuring instrument for manufacturing intelligent instruments and meters. In the manufacturing process of intelligent instruments and meters, it is necessary to perform quality inspection on the produced intelligent instruments, including the appearance, power supply, function and safety of the intelligent instruments. The analog output of the intelligent instruments can be inspected and calibrated by using a multimeter. The intelligent instrument is connected with the multimeter and the sensor. After the basic parameters of the intelligent instrument are set, the weight is placed on the gravity sensor, and then the data of the intelligent instrument is observed to be consistent with the analog quantity received by the multimeter, and then the intelligent instrument is inspected. However, this operation will cause the following problems: the user needs to use the multimeter to inspect a large number of intelligent instruments and meters. The instrument is tested, and during this process, the test wires of the multimeter need to be wired multiple times. Since the test wires are very long, the excess lengths of the two test wires will be entangled and knotted. The user needs to spend a lot of time to organize the test wires, resulting in low efficiency of the measurement and calibration work. By setting the adjustment structure, the positioning rod is first rotated, and the positioning rod is away from the mounting plate with the help of the thread, and the limit on the mounting plate is released. After the mounting plate is extended out of the mounting frame to a suitable length, the positioning rod is rotated in the opposite direction, and the positioning rod is moved toward the mounting plate with the help of the thread until the positioning rod is tightly against the mounting plate, and then the limit plate is pulled in the direction away from the mounting plate, and the limit plate drives the limit rod along the limit groove The spring is in a stretched state during the sliding process. When the limit plate is a certain distance away from the storage rod, the excess length of the test line is wound around the storage rod, and the limit plate is released. The spring in the stretched state gives the limit rod an elastic force, so that the limit rod and the limit plate move toward the storage rod until the limit plate squeezes the test line wound around the storage rod. The positioning rod is driven to rotate by turning the handle, which is convenient for the user to rotate the positioning rod. The pulley reduces the friction between the mounting plate and the inner wall of the mounting frame, so that the mounting plate moves more smoothly along the mounting frame. The anti-slip groove increases the friction between the mounting plate and the positioning rod, so that the limiting effect of the positioning rod is better. The rod is further limited, so that the limit rod is more stable when moving along the limit groove, and the reserved groove makes the limit plate fit more closely with the test line wound on the storage rod, so that the limit plate has a better limiting effect on the test line. After pulling the limit plate away from the storage rod, the auxiliary plate is rotated to resist the mounting plate, temporarily blocking the limit plate from resetting, making it convenient for the user to wind the test line with excess length, thereby realizing that the test line with excess length is wound around the storage rod, and the limit plate is used to limit the test line to prevent it from loosening, and the mounting plate can be flexibly adjusted and disassembled, which is highly practical and can effectively reduce the number and time of arranging the test lines during measurement and calibration operations, thereby improving the work efficiency of detection and calibration operations.

[0030] In the embodiments of the present invention, please refer to Figures 1 to 5The adjustment structure 7 includes a mounting frame 701, which is fixedly connected to the multimeter 2. The inner wall of the mounting frame 701 is slidably connected to a mounting plate 702. A positioning rod 703 is threadedly inserted on one side of the mounting frame 701. The positioning rod 703 passes through one side of the mounting frame 701 and abuts against the mounting plate 702. Both sides of the mounting plate 702 are fixedly connected to storage rods 707. The arc surface of the storage rod 707 is slidably connected to the test line 3. A limiting groove 708 is provided at one end of the mounting plate 702 away from the multimeter 2. The inner wall of the limiting groove 708 is slidably connected to a limiting rod 709. A spring 710 is fixedly connected to one end of the limiting rod 709 close to the mounting plate 702. The spring 710 is away from the limiting rod 7 The end of the positioning rod 703 away from the mounting frame 701 is fixedly connected to the handle 704. The positioning rod 703 is driven to rotate by rotating the handle 704, which is convenient for the user to rotate the positioning rod 703 and one side of the mounting frame 701 is rotated. Two pulleys 705 are connected, and the arc surfaces of the two pulleys 705 are slidably connected to the mounting plate 702. The pulleys 705 reduce the friction between the mounting plate 702 and the inner wall of the mounting frame 701, so that the mounting plate 702 can move more smoothly along the mounting frame 701. An anti-skid groove 706 is provided on the side of the mounting plate 702 close to the positioning rod 703. The inner wall of the anti-skid groove 706 is provided with a plurality of anti-skid patterns.

[0031] The working principle of a measuring instrument for manufacturing intelligent instruments and meters provided by the utility model is as follows: in the manufacturing process of intelligent instruments and meters, it is necessary to perform quality inspection on the produced intelligent instruments 1, including the appearance, power supply, function and safety of the intelligent instruments 1. The analog output of the intelligent instruments 1 can be inspected and calibrated using a multimeter 2. The intelligent instruments 1 are connected to the multimeter 2 and the sensor. After the basic parameters of the intelligent instruments 1 are set, the weights 6 are placed on the gravity sensor 5. Then, it is observed whether the data of the intelligent instruments 1 is consistent with the analog quantity received by the multimeter 2, and then the intelligent instruments 1 are inspected. However, this operation will cause the following problems. The user needs to use the multimeter 2 to inspect a large number of intelligent instruments 1. In this process, The test wires 3 of the multimeter 2 need to be wired multiple times. Since the test wires 3 are very long, the excess lengths of the two test wires 3 will be entangled and knotted. The user needs to spend a lot of time to organize the test wires 3, resulting in low efficiency of the measurement and calibration operation. By setting the adjustment structure 7, the positioning rod 703 is first rotated, and the positioning rod 703 is moved away from the mounting plate 702 by means of the thread, and the limit on the mounting plate 702 is released. After the mounting plate 702 is extended out of the mounting frame 701 to a suitable length, the positioning rod 703 is rotated in the opposite direction, and the positioning rod 703 is moved toward the mounting plate 702 by means of the thread until the positioning rod 703 is tightly against the mounting plate 702, and then the limit plate 712 is pulled away from the mounting plate 702, and the limit plate 712 drives the limit rod 709 The locking plate 712 is then released to lock the locking cam 708 in place and the locking cam 709 is in a state of tension. The slide groove 706 increases the friction between the mounting plate 702 and the positioning rod 703, so that the limiting effect of the positioning rod 703 is better. The limiting rod 709 is further limited by the slide rod 711, so that the limiting rod 709 is more stable when moving along the limiting groove 708. The reserved groove 713 makes the limiting plate 712 fit more closely with the test line 3 wound on the storage rod 707, so that the limiting plate 712 has a better limiting effect on the test line 3. After pulling the limiting plate 712 away from the storage rod 707, the auxiliary plate 714 is rotated to press against the mounting plate 702, temporarily blocking the limiting plate 712 from resetting, so that the user can wind the test line 3 of excess length, thereby realizing that the test line 3 of excess length is wound on the storage rod 707, and the test line 3 is limited by the limiting plate 712.To prevent it from loosening, the mounting plate 702 can be flexibly adjusted and disassembled, which is highly practical and can effectively reduce the number and time of arranging the test line 3 during measurement and calibration operations, thereby improving the work efficiency of detection and calibration operations.
