Description

Technical Field

[0001] The utility model relates to the technical field of electric power safety detection, and particularly relates to a resistance measuring rack. Background Art

[0002] A resistance meter is also called a megohmmeter. Most megohmmeters are powered by a hand-cranked generator, so it is called a megohmmeter. Its scale is in megohms. It is a commonly used measuring instrument for electricians, mainly used to check the insulation resistance of electrical equipment, household appliances or electrical circuits to the ground and between phases, so as to ensure that these equipment, appliances and circuits work in a normal state and avoid accidents such as electric shock casualties and equipment damage. At present, during the process of cranking the handle of the megohmmeter to generate electricity, vibrations will occur, so a measuring support frame is needed for fixation. The existing measuring racks are not convenient for adjusting the test angle of the megohmmeter during use, which will have a certain impact on the use of users.

[0003] After retrieval, Chinese Patent Application (Publication) No. 202223585279.3 discloses an auxiliary support frame for measuring a megohmmeter. This patent can conveniently adjust the angle of the megohmmeter by setting an orientation device. Although the above patent has the function of adjusting the angle, the operation of fixing the megohmmeter is relatively troublesome. When fixing, it is necessary to loosen multiple groups of rotating rods first, and then place the megohmmeter inside and tighten the rotating rods in sequence to fix the megohmmeter. And the current measuring support frame does not have the functions of storage and adaptation to multiple terrains. Therefore, it is very necessary to design a resistance measuring rack. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a resistance measuring rack, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A resistance measuring rack includes a support plate. One side of the upper surface of the support plate is fixedly connected with a vertical plate.

[0009] In order to achieve a flipping effect, as the resistance measuring rack of the present utility model, a sector seat is fixedly connected to one side of the lower surface of the support plate, and a support rod is rotatably connected inside the sector seat.

[0010] In order to achieve a positioning function, as the resistance measuring rack of the present utility model, positioning holes are formed on the outer surfaces of the sector seat and the support rod, and a second bolt is threadedly connected inside the positioning hole.

[0011] In order to achieve an effect of adjusting the height, as the resistance measuring rack of the present utility model, a support leg is sleeved at the bottom end of the support rod, and a third bolt is threadedly connected to one side of the outer surface of the support leg.

[0012] In order to achieve a function of adapting to various terrains, as the resistance measuring rack of the present utility model, a universal ball head is movably connected to the bottom end of the support leg, and a ground claw is fixedly connected to the lower surface of the universal ball head.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] 1. In the present utility model, through the settings of the transmission rod, worm gear, pressing plate and worm, during use, first place the resistance meter on the support plate. After rotating the worm, due to the meshing effect between the worm and the worm gear, the worm drives the worm gear to rotate, causing the transmission rod to rotate. By the rotation of the transmission rod, the sleeve is driven to make the pressing plate flip down and buckle on the resistance meter. The rubber pad contacts the resistance meter to have an anti-slip effect. Just rotate the worm to make the four groups of pressing plates press down simultaneously, which has the function of quickly fixing the resistance meter, and it can be locked after loosening the worm after fixation.

[0015] 2.

[0026] During specific use, first place the ohmmeter 8 on the support plate 1. After rotating the worm 10, due to the meshing effect between the worm 10 and the worm gear 4, the worm 10 drives the worm gear 4 to rotate, causing the transmission rod 3 to rotate. The rotation of the transmission rod 3 drives the sleeve 5, causing the pressing plate 6 to flip down and buckle on the ohmmeter 8. The contact between the rubber pad 7 and the ohmmeter 8 has an anti-slip effect. Just rotate the worm 10 to make the four pressing plates 6 press down simultaneously, which has the function of quickly fixing the ohmmeter 8, and it can be locked after loosening the worm 10 after fixation.

[0027] In this embodiment, the outer surface of the support plate 1 is coated with an insulating layer, and one side of the outer surface of the sleeve 5 is threadedly connected with a first bolt 11.

[0028] During specific use, after loosening the first bolt 11, the sleeve 5 can slide on the transmission rod 3, which is convenient for adjusting according to the width of the ohmmeter 8. After adjustment, tightening the first bolt 11 can fix the sleeve 5 on the transmission rod 3.

[0030] During specific use, the crank 13 has the function of facilitating the rotation of the worm 10. After the measuring frame is stored, the handle 12 has the function of facilitating lifting.

[0031] In this embodiment, a sector seat 14 is fixedly connected to one side of the lower surface of the support plate 1, and a support rod 15 is rotatably connected inside the sector seat 14.

[0032] During specific use, by using the rotation effect between the support rod 15 and the sector seat 14, the support rod 15 can be flipped to a vertical angle for support. After use, it can be flipped and stored again.

[0033] In this embodiment, positioning holes are formed on the outer surfaces of both the sector seat 14 and the support rod 15, and a second bolt 16 is threadedly connected inside the positioning holes.

[0034] During specific use, after loosening the second bolt 16, the support rod 15 can be flipped, and it can be fixed by tightening the second bolt 16 in the positioning hole.

[0035] In this embodiment, a support leg 17 is sleeved at the bottom end of the support rod 15, and a third bolt 18 is threadedly connected to one side of the outer surface of the support leg 17.

[0036] During specific use, by loosening the third bolt 18, the support rod 15 can be adjusted inside the support leg 17, which is convenient for adjusting the overall height. After adjustment, tightening the third bolt 18 can fix it.

[0037] In this embodiment, the bottom end of the support leg 17 is movably connected with a universal ball head 19, and the lower surface of the universal ball head 19 is fixedly connected with a ground claw 20.

[0038] During specific use, the ground claw 20 directly contacts the ground. In the face of complex terrains, the universal ball head 19 has a multi-directional rotation function, meeting the requirements of adapting to different terrains.

[0039] Working principle: During use, first loosen the second bolt 16, and utilize the rotation effect of the support rod 15 and the sector seat 14 to turn the support rod 15 to the vertical angle in sequence. Then, tighten the second bolt 16 in the positioning hole to fix it. Use the support rod 15 and the support leg 17 for support. The ground claw 20 directly contacts the ground. In the face of complex terrains, the universal ball head 19 has a multi-directional rotation function, meeting the requirements of adapting to different terrains. Place the resistance meter 8 on the support plate 1. After rotating the worm 10 through the crank 13, utilize the meshing effect of the worm 10 and the worm gear 4. The worm 10 drives the worm gear 4 to rotate, causing the transmission rod 3 to rotate. After the transmission rod 3 rotates, it drives the sleeve 5 to turn the pressing plate 6 down to buckle on the resistance meter 8. The rubber pad 7 contacts the resistance meter 8 to have an anti-slip effect. Just rotate the worm 10 to make the four groups of pressing plates 6 press down simultaneously, having the function of quickly fixing the resistance meter 8, and it can be locked after loosening the worm 10 after fixation. After use, loosen the second bolt 16 again, and the four groups of support rods 15 can be turned up to achieve the function of folding and storage.
