DETAILED DESCRIPTION

[0030] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The enumerated embodiments are only used to explain the present invention and are not used to limit the scope of the present invention.

[0031] Reference Figures 1 to 7 The present invention provides a resistance testing device for electrical measurement, including a support frame 1, a support plate 2 is rotatably installed in the support frame 1, a tester 3 is installed on the support plate 2, a support assembly for driving the support plate 2 to rotate is provided in the support frame 1, the support assembly includes a threaded rod 11 rotatably installed in the support frame 1, a moving block 12 threadedly sleeved on the threaded rod 11 and a support rod 13 rotatably installed on the moving block 12, the other end of the support rod 13 is rotatably connected to the lower surface of the support plate 2, one end of the threaded rod 11 passes through the support frame 1 and is fixedly installed with a rotating block 14, and an anti-slip groove is opened on the side of the rotating block 14.

[0032] Exemplarily, when the tester 3 is in use, the rotating block 14 can be rotated to drive the threaded rod 11 to rotate, and then the threaded rod 11 can be used to drive the moving block 12 to move in the support frame 1. When the moving block 12 moves toward the rotating block 14, the support plate 2 will be supported by the support rod 13, thereby driving the support plate 2 to rotate. When the support plate 2 rotates, the angle direction of the tester 3 can be adjusted during use, so that the tester 3 can be aimed at the tester, which is convenient for the tester to observe.

[0033] A placement block 4 is fixedly installed in the support frame 1, and placement grooves are symmetrically opened on the surface of the placement block 4. Test heads 5 are placed in the two placement grooves, and the test heads 5 are connected to the tester 3 through wires. A first clamping block 6 is symmetrically fixedly installed on the placement block 4, and a fixed block 7 is symmetrically fixedly installed on the surface of the placement block 4. Installation grooves are opened on the surfaces of the two fixed blocks 7. Slide blocks 9 are slidably installed in the installation grooves through telescopic springs 8. Second clamping blocks 10 are fixedly installed on the two slide blocks 9, and the test head 5 is located between the first clamping block 6 and the second clamping block 10.

[0034] Illustratively, under the action of the elastic force of the telescopic spring 8, the slider 9 has a tendency to move toward the direction of the first clamp 6. After the test head 5 is placed in the placement groove opened in the placement block 4, the slider 9 moves toward the test head 5 under the action of the elastic force of the telescopic spring 8, and then drives the second clamp 10 to move toward the test head 5 until the second clamp 10 contacts the test head 5. Under the joint action of the first clamp 6 and the second clamp 10, the test head 5 is stably clamped in the placement groove, thereby preventing the test head 5 from shaking inside the support frame 1 when the equipment is moved, thereby avoiding damage to the test head 5 and affecting the use of the equipment.

[0035] A U-shaped top rod 15 is horizontally slidably installed on the placement block 4 through two supporting blocks, and triangular blocks 16 are fixedly installed on the sides of the two second clamping blocks 10. The two ends of the top rod 15 are respectively in sliding contact with the inclined surfaces of the two triangular blocks 16, and a first spring rod 17 is fixedly installed on the top rod 15. The other end of the first spring rod 17 is fixedly connected to the inner wall of the support frame 1. A cross bar 18 is horizontally fixedly installed on the side of the support plate 2, and a pull rope 19 is fixedly installed on one end of the cross bar 18, and the other end of the pull rope 19 is fixedly installed on the top rod 15.

[0036] Exemplarily, when the support plate 2 rotates, the cross bar 18 pulls the pull rope 19, and then pulls the push rod 15 through the other end of the pull rope 19. Under the action of the support block, the push rod 15 is driven to move in the direction of the triangular block 16, so that one end of the push rod 15 contacts the inclined surface of the triangular block 16. Under the action of the inclined surface, the second clamping block 10 is driven to move in the direction of the telescopic spring 8, and then the slider 9 is driven to move in the slide groove. The telescopic spring 8 is compressed, and the push rod 15 moves while the first spring rod 17 is stretched, thereby driving the second clamping block 10 to separate from the test head 5, releasing the clamping fixation of the test head 5, so that when the test head 5 needs to be used, it is convenient to drive the second clamping block 10 to separate from the test head 5.

[0037] Protection pads are fixedly installed on the surfaces of the first clamping block 6 and the second clamping block 10, and the protection pads are made of rubber.

[0038] Exemplarily, when the first clamp block 6 and the second clamp block 10 are both in contact with the test head 5 , the protection pad can protect the test head 5 .

[0039] A support rod 21 is rotatably mounted on the protection plate 20 , and a positioning block 22 is fixedly mounted in the support frame 1 . A positioning groove is formed on the surface of the positioning block 22 , and one end of the support rod 21 is inserted into the positioning groove.

[0040] Exemplarily, when the test device is in use, the protection plate 20 is opened, and then the support rod 21 is rotated so that one end of the support rod 21 is inserted into a positioning groove provided on the surface of the positioning block 22, thereby locking the support rod 21, and then the protection plate 20 is supported by the support rod 21.

[0041] A first magnet 23 is fixedly mounted on the protection plate 20 , and a second magnet 24 is fixedly mounted on the support rod 21 . The magnetic poles of the first magnet 23 and the second magnet 24 are opposite.

[0042] Exemplarily, when the test equipment is not in use, the protective plate 20 is covered on the support frame 1, and the protective plate 20 protects the tester 3 in the support frame 1. Before covering the protective plate 20, one end of the support rod 21 is moved out of the positioning groove, and then the support rod 21 is rotated to make the second magnet 24 fixedly mounted on the support rod 21 contact with the first magnet 23 fixedly mounted on the protective plate 20. Under the action of the magnetic force, the support rod 21 is locked, so that after covering the protective plate 20, the support rod 21 is prevented from shaking in the support frame 1 when the test equipment is moved.

[0043] A mounting block 25 is fixedly installed on the support frame 1, and a card slot is opened on the mounting block 25. Both sides of the mounting block 25 are opened with movable holes connected to the card slot, and limit rods 26 are slidably installed in the two movable holes. One end of the two limit rods 26 is fixedly installed with a second spring rod 27, and the other end of the two second spring rods 27 is fixedly installed with a connecting block 28. The two connecting blocks 28 are fixedly installed on the support frame 1, and the two limit rods 26 are fixedly installed with a pull block 29. A card block 30 is fixedly installed on the protective plate 20, and both ends of the card block 30 are provided with a limiting slot.

[0044] Exemplarily, before covering the protective plate 20, the two limit rods 26 are pulled by the pull block 29 to drive the two limit rods 26 away from each other, the second spring rod 27 is compressed, and then the cover protective plate 20 is covered. During this process, the protective plate 20 will drive the clamping block 30 to be clamped in the clamping groove opened on the mounting block 25, and then the two pull blocks 29 are released. Under the action of the elastic force of the second spring rod 27, the two limit rods 26 approach each other until the two limit rods 26 are respectively inserted into the limit grooves opened at both ends of the clamping block 30, thereby locking the protective plate 20, and then the protective plate 20 can provide better protection for the equipment in the support frame 1.

[0045] In the present invention, under the action of the elastic force of the telescopic spring 8, the slider 9 has a tendency to move toward the first clamping block 6. When the test head 5 is placed in the placement groove opened in the placement block 4, the slider 9 moves toward the test head 5 under the action of the elastic force of the telescopic spring 8, and then drives the second clamping block 10 to move toward the test head 5 until the second clamping block 10 contacts the test head 5. Under the joint action of the first clamping block 6 and the second clamping block 10, the test head 5 is stably clamped in the placement groove, thereby preventing the test head 5 from shaking inside the support frame 1 when the equipment is moved, avoiding damage to the test head 5 and affecting the use of the equipment.

[0046] It should be noted that the tester 3, test head 5 and other components used in this application are all existing electronic components in the field. Those skilled in the art can understand the circuit structure of the tester 3, test head 5 and other electronic components and the circuit connection structure between each other based on the existing public technical knowledge and technical information. The embodiment of this application will not elaborate on this, and those skilled in the art can freely choose the corresponding model according to their needs. This embodiment does not make any specific restrictions here.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
