DETAILED DESCRIPTION

[0020] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0021] The first embodiment of the present application is:

[0022] See also Figure 1-Figure 4 ,in Figure 1 It is a left view of the first embodiment of the utility model. Figure 2 The utility model Figure 1 AA line section view, Figure 3 The utility model Figure 2 The enlarged view of the local structure at B, Figure 4 The utility model Figure 2 Enlarged view of the local structure at location C.

[0023] The utility model provides a measuring instrument detection and calibration device, including a support base 101, a moving component 102, two groups of synchronization components 103 and a pressure measuring component 104, each group of the synchronization components 103 includes an insertion rod 105, a limit rod 106 and a limit plate 107, the support base 101 includes a base 108, a first side plate 109 and a second side plate 110, the moving component 102 includes a motor 111, a threaded rod 112, a vertical plate 113 and two hanging rings 114, and the pressure measuring component 104 includes a plurality of spring members 115 and a pressure sensor 116.

[0024] According to this specific embodiment, the pressure measuring assembly 104 is fixedly connected to the moving assembly 102, the moving assembly 102 is fixedly connected to the supporting seat 101, the limiting plate 107 is fixedly connected to the limiting rod 106, the limiting rod 106 is detachably connected to the plug rod 105, the plug rod 105 is fixedly connected to the pressure measuring assembly 104, the second side plate 110 is fixedly connected to the base 108, the first side plate 109 is fixedly connected to the base 108, one of the hanging rings 114 is fixedly connected to the vertical plate 113, the other hanging ring 114 is fixedly connected to the second side plate 110, the vertical plate 113 is rotatably connected to the threaded rod 112, and the threaded rod 112 is One end is fixedly connected to the output end of the motor 111, the other end of the threaded rod 112 is rotatably connected to the second side plate 110, one end of each of the spring members 115 is fixedly connected to the pressure sensor 116, and the other end of each of the spring members 115 is fixedly connected to the vertical plate 113. The two inserted rods 105 currently provided can slide following the length of the instrument to be measured. After the moving assembly 102 is moved to the target position, the limit rod 106 is inserted for fixation. This design ensures that the pressure measuring assembly 104 will not affect the measurement data due to changes in distance, and solves the problem that the position of the pressure testing mechanism cannot be adjusted when testing measuring instruments of different lengths, resulting in large errors in actual detection results.

[0025] Among them, the pressure measuring component 104 is located on one side of the moving component 102, and the moving component 102 is located above the support seat 101, the limit plate 107 is located on the peripheral side of the limit rod 106, and the limit rod 106 is located on one side of the insertion rod 105, and the insertion rod 105 is located on one side of the pressure measuring component 104. When installing the measuring instrument to be measured, first adjust the position of the vertical plate 113 to keep it consistent with the length of the measuring instrument to be measured. Since the movement of the vertical plate 113 drives the movement of the two insertion rods 105, after the position of the vertical plate 113 is adjusted, the limit rod 106 is inserted into the insertion rod 105 close to the jack on the first side plate 109 to prevent the pressure sensor 116 from moving again, thereby ensuring that the spring member 115 will not be deformed and no pressure is generated on the pressure sensor 116, then the motor 111 can be started to start the measurement work.

[0026] Secondly, the second side plate 110 is located on one side of the base 108, and the first side plate 109 is located on the other side of the base 108, one of the hanging rings 114 is located on one side of the vertical plate 113, and the other hanging ring 114 is located on one side of the second side plate 110, the vertical plate 113 is located on the peripheral side of the threaded rod 112, and the other end of the threaded rod 112 is located on one side of the second side plate 110, the first side plate 109 and the second side plate 110 are both fixed on the base 108, the hanging ring 114 on the second side plate 110 and the hanging ring 114 on the vertical plate 113 work together to involve the measuring instrument to be measured, and as the motor 111 is started, the threaded rod 112 rotates, thereby driving the vertical plate 113 to move, and the vertical plate 113 moves toward the pressure sensor 116 and gradually measures the tension value of the measuring instrument.

[0027] At the same time, one end of each of the spring members 115 is located on one side of the pressure sensor 116, and the other end of each of the spring members 115 is located on the side of the vertical plate 113 away from the hanging ring 114. Each of the spring members 115 includes a supporting plate and a retractable rod including a spring. When the hanging ring 114 on the vertical plate 113 pulls the measuring instrument, the vertical plate 113 applies a reverse force to each of the spring members 115 and transmits it to the pressure sensor 116. The pressure measured by the pressure sensor 116 is exactly the pulling force of the measuring instrument.

[0028] In this embodiment, the two inserted rods 105 are now arranged to slide along with the length of the instrument to be measured. After the moving assembly 102 is moved to the target position, the limiting rod 106 is inserted to fix it. This design ensures that the pressure measuring assembly 104 will not affect the measurement data due to the change in distance, and solves the problem that when testing measuring instruments of different lengths, the position of the pressure testing mechanism cannot be adjusted, and the actual detection result has a large error. When installing the measuring instrument to be measured, the position of the vertical plate 113 is first adjusted to be consistent with the length of the measuring instrument to be measured. Since the movement of the vertical plate 113 drives the movement of the two inserted rods 105, after the position of the vertical plate 113 is adjusted, the limiting rod 106 is inserted into the insertion hole of the inserted rod 105 close to the first side plate 109 to prevent the pressure sensor 116 from moving again, thereby ensuring that the spring member 115 will not be deformed and there is no impact on the pressure sensor. When the pressure sensor 116 generates pressure, the motor 111 can be started to start the measurement work. The first side plate 109 and the second side plate 110 are both fixed on the base 108. The hanging ring 114 on the second side plate 110 and the hanging ring 114 on the vertical plate 113 work together to involve the measuring instrument to be measured. As the motor 111 is started, the threaded rod 112 rotates, thereby driving the vertical plate 113 to move. The vertical plate 113 moves toward the direction of the pressure sensor 116 and gradually measures the tension value of the measuring instrument. Each of the spring members 115 includes a supporting plate and a retracting rod including a spring. When the hanging ring 114 on the vertical plate 113 pulls the measuring instrument, the vertical plate 113 applies a reverse force to each of the spring members 115 and transmits it to the pressure sensor 116. The pressure measured by the pressure sensor 116 is exactly the tension of the measuring instrument.

The stabilizing frame 202 is fixedly connected to the mounting plate 201 and is located below the mounting plate 201. The mounting plate 201 is fixedly connected to the second side plate 110 and is located above the second side plate 110. The measuring instrument to be measured is prepared to be tested under the installation of the two hanging rings 114. Before the test, the measuring instrument is prone to shaking. In order to prevent shaking before measurement and affect the final test results, the stabilizing frame 202 currently set up cooperates with the stabilizing rod 203 to effectively prevent the measuring instrument from shaking. The staff adjusts the width of the stabilizing frame 202 by rotating the stabilizing rod 203. The operation is convenient and simple, and the actual test results are more accurate.
