[0002] In the prior art, current sensors usually need to be calibrated and tested by relevant detection devices. Common detection devices are usually equipped with a grabbing component. During detection, the current sensor is placed on a placement plate. The detection device is provided with a placement rack. Most placement plates are placed directly on the placement rack. The grabbing component grabs and tests the current sensor. If the placement plate is accidentally bumped and positionally shifted, it is very easy to cause the grabbing component of the detection device to be unable to accurately grab the current sensor normally, resulting in the current sensor being unable to be detected in time, which seriously affects the efficiency of the detection device in performing parameter calibration and testing on the current sensor. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] like Figure 1-4As shown, the utility model provides a technical solution: a current sensor parameter calibration and detection device, comprising: a device body 1, a placement rack 2 is fixedly connected to one side of the device body 1, a fixing groove adapted to the fixing block 42 is opened on one side of the placement rack 2, and the fixing groove is opened, so that the fixing block 42 can be normally inserted into the interior of the placement rack 2, so that the placement disk 3 and the placement rack 2 can be normally connected, a card slot adapted to the card block 43 is opened on one side of the fixing block 42, and the card slot is opened, so that the card block 43 can be normally inserted into the interior of the fixing block 42, so that the fixing block 42 can be fixed in the interior of the placement rack 2 with the help of the card block 43, so that when the placement disk 3 is placed on the placement rack 2, a good fixing measure can be maintained with the help of the fixing block 42 and the card block 43, thereby reducing the position movement of the placement disk 3 on the placement rack 2, a fixing mechanism 4 is provided on one side of the placement rack 2, a current sensor body 5 is provided on the placement disk 3, and a card slot adapted to the current sensor body 5 is opened on one side of the placement disk 3 The mounting plate 43 is fixedly connected to the mounting plate 41 on one side of the mounting frame 2, and a fixing block 42 is fixedly connected to one side of the mounting plate 3. A block 43 is slidably passed through the interior of the mounting frame 2, and a slide groove 48 is provided on one side of the block 43 to match the slide rod 46. By opening the slide groove 48, the block 43 can slide on the outer surface of the push rod 47 to prevent the push rod 47 from being inserted into the block 43 and causing the block 43 to be unable to move normally.

[0025] Example 2

[0026] like Figure 3As shown, the elastic mechanism 44 includes a limit plate 441 fixedly connected to one side of the card block 43, a limit rod 442 fixedly connected to the interior of the placement rack 2, a spring 443 is sleeved on the outer surface of the limit rod 442, and a limit groove adapted to the limit plate 441 is opened inside the placement rack 2. By opening the limit groove, the limit plate 441 can move normally inside the placement rack 2, so that there is a good anti-slip measure between the card block 43 and the placement rack 2, and a limit hole adapted to the limit rod 442 is opened on one side of the limit plate 441. By opening the limit hole, the limit plate 44 During the movement of 1, the limiting rod 442 can be used to maintain a good movement limit, so as to avoid the locking phenomenon caused by position offset during the movement of the limiting plate 441, so that the clamping block 43 can move normally. One end of the spring 443 is welded to one side of the inner wall of the limiting groove, and the other end of the spring 443 is welded to one side of the limiting plate 441. By setting the spring 443, the spring 443 provides sufficient elastic force, so that the limiting plate 441 can maintain a good position and stability inside the placement rack 2 with the help of the elastic force of the spring 443, so that the clamping block 43 can be stably inserted into the inside of the clamping block 43.

[0027] Working principle:

[0028] like Figure 1-4As shown, when in use, the placement tray 3 on which the current sensor product that needs to be calibrated and tested for parameters is placed is placed on the placement rack 2. During the placement of the placement tray 3, the fixing block 42 is used to position it, and the fixing block 42 is gradually inserted into the interior of the placement rack 2. After the fixing block 42 is inserted into the interior of the placement rack 2, the placement tray 3 is slowly pressed to move, and the placement tray 3 gradually approaches the placement rack 2, and the fixing block 42 gradually moves into the interior of the placement rack 2. As the fixing block 42 moves inside the placement rack 2, the fixing block 42 gradually contacts the clamping block 43 inside the placement rack 2. One side of the clamping block 43 is set to an inclined surface. After the fixing block 42 contacts the clamping block 43, continue to press the placement tray 3 to move, and the fixing block 42 continues to move inside the placement rack 2. The clamping block 43 is affected by the force of the continued movement of the fixing block 42 and actively moves into the interior of the placement rack 2. During the movement of the clamping block 43, the clamping block 43 gradually The spring 443 is no longer affected by the force, and its shape gradually recovers, and in the process of recovery, it drives the limit plate 441 to move. In the process of movement of the limit plate 441, it drives the block 43 to move, and the block 43 is removed from the inside of the placement rack 2 and inserted into the inside of the fixed block 42, that is, the placement rack 3 and the placement rack 2 are fixed. The device body 1 is started to run, and the current sensor product on the placement rack 3 is calibrated and tested.

[0029] When the placement tray 3 is removed, the push plate 41 is pushed to move. During the movement of the push plate 41, the connecting rod 45 is driven to move. The connecting rod 45 slides on the outer surface of the slide rod 46 and drives the push rod 47 to move during the movement. During the movement of the push rod 47, the limiting plate 441 is driven to move. The blocking block 43 gradually moves following the movement of the limiting plate 441 and gradually moves out from the inside of the fixed block 42 until the push plate 41 can no longer be pushed and the position after the push plate 41 is pushed is kept stationary, dragging the placement tray 3 to move, and the placement tray 3 gradually separates from the placement rack 2. The fixed block 42 gradually moves out from the inside of the placement rack 2 following the movement of the placement tray 3 until the placement tray 3 is completely separated from the placement rack 2, and the placement tray 3 can be removed from the placement rack 2.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
