Description

Technical Field

[0001] The utility model relates to the technical field of mechanical metrology detection, in particular to a mechanical metrology detection instrument which is convenient for replacing a detection head. Background Art

[0002] Mechanical metrology is the metrological science that studies the theory and practice of mechanical measurement in the process of transforming mechanical phenomena from qualitative to quantitative descriptions. It is generally considered to include the measurement of physical quantities such as mass, capacity, pressure, flow, density, force, torque, power, and displacement, velocity, and acceleration that describe the motion of vibrating objects. It also includes instrument calibration parameters such as hardness that characterizes the mechanical properties of materials, as well as the measurement of the fundamental physical constant, gravity acceleration. A magnetometer (Gaussmeter) is used when necessary for magnetic detection.

[0003] A digital roller gaussmeter with patent number CN220730408U includes a meter box, a digital meter, leads, a Hall sensor, a boost circuit and a parallel voltage stabilization circuit. The boost circuit and the parallel voltage stabilization circuit are both installed in the gaussmeter. The gaussmeter is provided with a zero adjustment and correction circuit. The roller gaussmeter is equipped with a replaceable pen-shaped Hall probe.

[0004] However, research has shown that existing Gaussmeters still have the following defects:

[0005] The existing Gaussmeter connects the Gaussmeter and the detection head to each other by plugging them in. When replacing, you only need to pull the connector out of the connector port, which is relatively convenient. However, when the wire encounters an obstacle and is pulled, the wire drives the connector to swing left and right in the connector port, which will cause damage to the connector port and the connector head. When the pulling force is too large, the connector head may be pulled out of the connector port by the wire, resulting in measurement failure. Therefore, it is necessary to optimize a mechanical metrology tester that is easy to replace the detection head through technological innovation and design optimization. Utility Model Content

[0006] The existing Gaussmeter connects the Gaussmeter and the detection head to each other by plugging. When replacing, you only need to pull the connector out of the connector port, which is relatively convenient. However, when the wire encounters an obstacle and is pulled, the wire drives the connector head to swing left and right in the connector port, which will cause damage to the connector port and the connector head. When the pulling force is too large, the connector head may be pulled out of the connector port by the wire, thereby causing measurement failure. In order to solve the above problems, the embodiment of the present application provides a mechanical metrology tester that is easy to replace the detection head. By setting a plug-in mechanism, the plug-in board is inserted into the slot, thereby avoiding the connection block driving the connector head to swing left and right in the connector port when the wire is pulled, causing damage to the connector port and the connector head, thereby improving the service life of the connector head and the connector port. At the same time, the connection block and the measuring instrument body are limited by the limiting mechanism to avoid excessive pulling force from pulling the connector head out of the connector port, thereby causing detection failure.

[0007] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0008] A mechanical metrology tester with an easily replaceable test head, comprising:

[0009] The measuring instrument body has a detection head body on one side of the measuring instrument body, an electric wire is connected to the detection head body facing the measuring instrument body, a connecting block is fixed to the other end of the electric wire, a connecting head is fixed to the connecting block on the side facing the measuring instrument body, a connecting port is provided on the measuring instrument body, a plug-in mechanism is provided between the connecting head and the measuring instrument body, and a more secure limiting mechanism is provided on the measuring instrument body to assist the plug-in mechanism in plugging in.

[0010] In one possible implementation, the plug-in mechanism includes a slot provided on the measuring instrument body, and a plug-in plate is fixed on the connecting block. The plug-in plate can be inserted into the slot to prevent the connecting block from driving the connecting head to swing left and right in the connecting port when the wire is pulled.

[0011] In one possible implementation, an iron block is fixed on the side of the plug plate facing the measuring instrument body, and a magnet is fixed inside the slot. The magnet and the block can attract each other, and the magnetic force of the magnet on the iron block can guide the plug plate, while also reducing the possibility of pulling the connector out of the connection block mouth when pulling the wire.

[0012] In one possible implementation, the limiting mechanism includes a sliding groove provided on the measuring instrument body, a sliding block provided in the sliding groove, a spring provided in the sliding groove, a limiting block fixed on the sliding block, a limiting groove provided on the plug plate, and the limiting block can be inserted into the limiting groove. Under the action of the spring, the spring drives the sliding block to move, and the sliding block drives the limiting block to move, so that the limiting block is inserted into the limiting groove provided on the plug plate.

[0013] In one possible implementation, a guide column is provided inside the slot, the guide column passes through the sliding block and is fixedly connected to both sides of the sliding slot, the spring sleeve is provided outside the guide column, and the sliding block can slide on the sliding slot to prevent the sliding block from falling off from the sliding slot.

[0014] In one possible implementation, the limit block is provided with an inclined surface at one end away from the spring, and the inclined surface faces the wire. When the plug-in board contacts the inclined surface of the limit block, the limit block will be squeezed, and the limit block will drive the sliding block to squeeze the spring. When the limit slot on the plug-in board is opposite to the limit block, the limit block will be inserted into the limit slot under the action of the spring, and there is no need to manually pull the limit block to insert the plug-in board into the slot.

[0015] In a possible implementation, an arc-shaped plate is fixed on the limit block, with the concave side of the arc-shaped plate facing the wire. When the middle finger and index finger are used to push the arc-shaped plate, the arc-shaped plate will drive the limit block to move out of the limit groove.

[0016] In a possible implementation, the connector can be inserted into the connection port, and the connector is electrically connected to the connection port, so as to facilitate the connection between the measuring instrument body and the detection head body.

[0017] In summary, the present invention has at least one of the following beneficial technical effects:

[0018] 1. By setting up a plug-in mechanism, the plug-in board can be inserted into the slot to avoid the connection block driving the connector to shake left and right in the connection port when pulling the wire, thereby improving the service life of the connector and the connection port;

[0019] 2. The connection block and the measuring instrument body are limited by the limiting mechanism to prevent the connector from being pulled out of the connection port due to excessive tension, thereby causing detection failure. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the present invention to clearly and completely describe the technical solution of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The instrument placement rack involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] This embodiment introduces a specific structure of a mechanical metrology tester that is convenient for replacing the test head. Figure 1-Figure 5 As shown, a mechanical metrology tester with easy replacement of the test head comprises:

[0028] The measuring instrument body 1 has a detection head body 5 on one side of the measuring instrument body 1, a wire 4 is connected to the detection head body 5 on the side facing the measuring instrument body 1, a connecting block 3 is fixed to the other end of the wire 4, a connector 17 is fixed to the side of the connecting block 3 facing the measuring instrument body 1, a connecting port 6 is provided on the measuring instrument body 1, a plug-in mechanism is provided between the connector 17 and the measuring instrument body 1, and a more secure limiting mechanism is provided on the measuring instrument body 1 to assist the plug-in mechanism in plugging.

[0029] When the wire 4 is pulled, the wire 4 will drive the connector 17 to shake in the connection port 6 , which will cause damage to the connection port 6 and the connector 17 over time.

[0030] In one possible implementation, the plug-in mechanism includes a slot 7 provided on the measuring instrument body 1, and a plug-in board 2 is fixed on the connecting block 3. The plug-in board 2 can be inserted into the slot 7 to prevent the connecting block 3 from driving the connecting head 17 to swing left and right in the connecting port 6 when the wire 4 is pulled.

[0031] In one possible implementation, an iron block 16 is fixed to the side of the plug board 2 facing the measuring instrument body 1, and a magnet 9 is fixed inside the slot 7. The magnet 9 and this block can attract each other. The magnetic force of the magnet 9 on the iron block 16 can guide the plug board 2, and at the same time, it can also reduce the possibility of pulling the connector 17 out of the mouth of the connecting block 3 when the wire 4 is pulled.

[0032] When the force of pulling the wire 4 is greater than the magnetic force, the plugboard 2 will be removed from the slot 7, causing the measurement to fail.

[0033] In one possible implementation, the limiting mechanism includes a sliding groove 13 provided on the measuring instrument body 1, a sliding block 10 is provided in the sliding groove 13, a spring 11 is provided in the sliding groove 13, a limiting block 8 is fixed on the sliding block 10, a limiting groove 15 is provided on the plug plate 2, and the limiting block 8 can be inserted into the limiting groove 15. Under the action of the spring 11, the spring 11 drives the sliding block 10 to move, and the sliding block 10 drives the limiting block 8 to move, so that the limiting block 8 is inserted into the limiting groove 15 provided on the plug plate 2.

[0034] When there is a pulling force to stretch the connecting block 3 , the inserting plate 2 will pull the limiting block 8 , and the limiting block 8 will pull the sliding block 10 , which may cause the sliding block 10 to fall off from the sliding groove 13 .

[0035] In one possible implementation, a guide column 12 is provided inside the slot 7, the guide column 12 passes through the sliding block 10 and is fixedly connected to both sides of the sliding groove 13, the spring 11 is sleeved on the outside of the guide column 12, and the sliding block 10 can slide on the sliding groove 13 to prevent the sliding block 10 from falling off from the sliding groove 13.

[0036] When inserting the plugboard 2 into the slot 7 , it is necessary to manually pull the limit block 8 outward first, otherwise the limit block 8 will prevent the plugboard 2 from being inserted into the slot 7 .

[0037] In one possible implementation, the end of the limit block 8 away from the spring 11 is set with an inclined surface, and the inclined surface faces the wire 4. When the plug board 2 contacts the inclined surface of the limit block 8, it will squeeze the limit block 8, and the limit block 8 will drive the sliding block 10 to squeeze the spring 11. When the limit groove 15 on the plug board 2 is opposite to the limit block 8, the limit block 8 will be inserted into the limit groove 15 under the action of the spring 11, and there is no need to manually pull the limit block 8 to insert the plug board 2 into the slot 7.

[0038] In one possible implementation, an arc-shaped plate 14 is fixed on the limit block 8, with the concave side of the arc-shaped plate 14 facing the wire 4. When the middle finger and index finger push the arc-shaped plate 14, the arc-shaped plate 14 will drive the limit block 8 to move out of the limit groove 15.

[0039] In a possible implementation, the connector 17 can be inserted into the connection port 6 , and the connector 17 is electrically connected to the connection port 6 , so as to facilitate the connection between the measuring instrument body and the detection head body 5 .

[0040] When the staff needs to replace the detection head, they first pull the limit block 8 through the curved plate 14. The limit block 8 will squeeze the spring 11, and the connecting head 17 will be pulled out of the connecting port 6 through the connecting block 3. At the same time, the plug-in board 2 will be moved out of the slot 7, and the plug-in board 2 on the new detection head body 5 will be aligned with the slot 7 and inserted. When the plug-in board 2 contacts the inclined surface of the limit block 8, it will squeeze the limit block 8, and the limit block 8 will drive the sliding block 10 to squeeze the spring 11. When the limit groove 15 on the plug-in board 2 is opposite to the limit block 8, the limit block 8 will be inserted into the limit groove 15 under the action of the spring 11. There is no need to manually pull the limit block 8 to insert the plug-in board 2 into the slot 7, and the operation is relatively simple.

[0041] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
