[0025] Reference ​ An electrical impact experiment clamp, comprising a base plate 1 and a fixed plate 101 in contact with an electrical component, a plurality of mounting holes can be arranged on the base plate 1 to facilitate an operator to fix the base plate 1 on a detection table. In specific use, the operator can arrange a plurality of threaded holes at different positions on the detection table to fix the base plate 1 at any position, so as to find a suitable fixing point.

[0026] The first support plate 102 is arranged on the top of the base plate 1, and the second support plate 103 is arranged on the top of the base plate 1, and the second support plate 103 is arranged between the two first support plates 102 (the first support plate 102 and the second support plate 103 can be integrally formed with the base plate 1), and the connecting plate 104 is rotatably connected to the second support plate 103, and the fixed plate 101 is arranged at the bottom of the connecting plate 104, and the adjusting assembly for adjusting the position of the fixed plate 101 is arranged on the connecting plate 104, and the manual fixing mechanism for fixing the connecting plate 104 is arranged on the base plate 1.

[0027] In use, the operator can fix the base plate 1 at any position on the detection table to find a suitable fixing point, and then place the measured object on the detection table. Then, rotate the connecting plate 104 so that the fixed plate 101 on the connecting plate 104 is in contact with the measured object. Finally, use the manual fixing mechanism to fix the connecting plate 104 to prevent it from rotating, so as to firmly fix the measured object on the detection table.

[0028] By arranging the manual fixing mechanism, the operator can manually adjust the fixing position of the connecting plate 104 when clamping different models of electrical components, so that the fixed plate 101 can adapt to electrical components of different thicknesses. In this way, the operator does not need to debug the clamp, which reduces the technical requirements and makes the operation more convenient and easy to use. The adjusting assembly arranged can make the clamp find a suitable fixing point according to the actual size of the measured object, so as to increase the contact area between the fixed plate 101 and the measured object and improve the fixing effect.

[0029] Specifically, the two connecting rods 2, the pressing plate 201 for pressing the connecting plate 104, and the pushing assembly for pushing the pressing plate 201 to press the connecting plate 104, one end of the two connecting rods 2 is rotatably connected with the corresponding second support plate 103, the pushing assembly comprises a containing block 202, a pushing rod 203, and a pushing screw 204, two sides of the containing block 202 are rotatably connected with the corresponding first support plate 102, the containing block 202 is internally provided with a containing groove 205, the pushing screw 204 is arranged inside the containing groove 205 and is rotatably connected with the inner wall of the containing groove 205, one side of the pushing rod 203 is provided with a sliding block 206, the sliding block 206 is slidably connected with the inner wall of the containing groove 205, and the sliding block 206 is threadedly connected with the pushing screw 204, the other end of the connecting rod 2 and one end of the pressing plate 201 are rotatably connected with the side of the pushing rod 203 away from the containing block 202, the other end of the pressing plate 201 is rotatably connected with the connecting plate 104, the side of the pressing plate 201 away from the containing block 202 is provided with a pressing portion 207, and the pressing portion 207 abuts against the top of the connecting plate 104, and the pressing portion 207 can be integrally formed with the pressing plate 201 to improve the strength of the pressing plate 201.

[0030] In use, the operator rotates the pushing screw 204, the pushing screw 204 drives the sliding block 206 to move in the containing groove, and the sliding block 206 moves towards the position of the first support plate 102. The side of the sliding block 206 pushes the two connecting rods 2 to rotate around the corresponding second support plate 103. At the same time, the pressing plate 201 rotates around the connecting plate 104, and the pressing portion 207 on the pressing plate 201 presses the connecting plate 104, so that the connecting plate 104 drives the fixing plate 101 to fix the measured object. Since the threaded connection has self-locking property, the fixing plate 101 can stably fix the measured object. In addition, when the pushing rod 203 pushes the connecting rod 2 to rotate, the containing block 202 also rotates adaptively. The manual fixing mechanism in the embodiment only needs the operator to manually rotate the pushing screw 204 to realize the fixation of the measured object, without additional complex operation, further improving the operation convenience. In addition, when clamping an electric component with large thickness, the operator can increase a pad block at the bottom of the base plate 1 to increase the height of the clamp, so as to adapt to the thicker electric component.

[0031] Further, in order to prevent the sliding block 206 from deviating or mispositioning during movement, a guide rod 208 is fixedly connected with the inner wall of the containing groove 205, and the sliding block 206 is slidably connected with the guide rod 208. The guide rod 208 can limit the degree of freedom of the sliding block 206, so that the sliding block 206 can only move along the axis direction of the guide rod 208, preventing the sliding block 206 from deviating or mispositioning during movement, thereby improving the stability of the pushing assembly.

[0032] In order to facilitate the operator to rotate the pushing screw 204, the pushing screw 204 is penetrated through the side of the accommodating block 202 and extends to the accommodating block 202 from the side of the first supporting plate 102, and the rotating handle 209 is fixedly connected to the side of the pushing screw 204 away from the accommodating block 202. By arranging the rotating handle 209, the contact area of the pushing screw 204 is increased, the operator can rotate the pushing screw 204 conveniently, and the convenience of operation is improved.

[0033] In the embodiment, the adjusting assembly comprises an adjusting screw 3, two adjusting plates 301 and adjusting bolts 302 arranged at both ends of the adjusting screw 3. The two adjusting plates 301 are arranged at the top and bottom of the connecting plate 104 respectively, and are slidingly connected to the connecting plate 104. The adjusting screw 3 is threadedly connected to the adjusting plate 301, and one side of the adjusting bolt 302 abuts against the adjusting plate 301. The fixing plate 101 is arranged at the bottom of the adjusting screw 3.

[0034] When the staff needs to adjust the position of the fixing plate 101, the adjusting screw 3 is first fixed to prevent the adjusting bolt 302 from rotating. Then, the adjusting bolts 302 are loosened by using a tool, so that the adjusting bolts 302 are separated from the adjusting plate 301. At this time, the operator can move the adjusting plate 301 on the connecting plate 104, and after adjusting to the appropriate position, the adjusting bolt 302 is tightened to make one side of the adjusting bolt 302 abut against the adjusting plate 301, and the adjusting plate 301 is fixed on the connecting plate 104 under the action of friction.

[0035] When the connecting plate 104 is rotated under the driving of the pressing plate 201, due to the rotating movement of the connecting plate 104, the fixing plate 101 may not be in full contact with the measured object when fixing different sizes of electrical components, thereby reducing the fixing effect.

[0036] In the embodiment, in order to improve the fixing effect of the fixing plate 101, the connecting block 303 is fixedly connected to the bottom of the adjusting screw 3. The connecting block 303 and the bottom of the adjusting screw 3 can be fixed together by welding. The rotating groove 304 is arranged in the connecting block 303. The connecting column 305 is fixedly connected to the top of the fixing plate 101, and the connecting column 305 is rotatably connected to the inner wall of the rotating groove 304.

[0037] The connecting column 305 is rotatably connected to the rotating groove 304, so that the fixing plate 101 can be self-adaptively adjusted in the clamping direction, the surface of the fixing plate 101 is ensured to be in full contact with the surface of the measured object, and the fixing effect is improved.

[0038] Further, the top of the connecting column 305 is in a spherical shape structure, and the connecting column 305 is in rolling connection with the rotating groove 304 at one end of the spherical shape structure. The connecting column 305 is designed in a spherical shape, which can make the connecting column 305 rotate more smoothly in the rotating groove 304, and reduce the phenomenon of jamming. Secondly, it can improve the rotating angle of the fixed plate 101, and increase the adjustment angle of the fixed plate 101.

[0039] Working principle:

[0040] In use, the operator can fix the bottom plate 1 at any position on the detection table to find a suitable fixed point; then the measured object is placed on the detection table. Next, rotate the rotating handle 209, which will drive the push screw 204 to rotate, and the push screw 204 drives the sliding block 206 to move in the accommodation, so that the sliding block 206 moves towards the position of the first supporting plate 102. The sliding block 206 will push the two connecting rods 2 to rotate around the corresponding second supporting plate 103. At the same time, the extrusion plate 201 will rotate around the connecting plate 104, driving the extrusion part 207 on the extrusion plate 201 to extrude the connecting plate 104, so that the connecting plate 104 drives the fixed plate 101 to fix the measured object. When the detection is completed, rotate the rotating handle 209 in the opposite direction, and the measured object can be removed.

[0041] The above is only a preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
