[0027] The electrical appliance to be tested may be a high-voltage tester or other electrical appliance that is prone to discharge during a withstand voltage test.
[0028] The test bracket is used to support the electrical appliance to be tested during the test so as to achieve the purpose of suspending the electrical appliance to be tested.
[0029] Specifically, the test bracket includes a support portion 1 , and the electrical appliance to be tested is set up on the support portion 1 .
[0030] Among them, at least two support parts 1 are provided, and at least two support parts 1 are arranged opposite to each other along the first direction. For example, two, three, or four support parts 1 are provided. In the embodiment of the present application, the electrical appliance to be tested is a high-voltage tester, the first direction is the length direction of the high-voltage tester, two support parts 1 are provided, and the two support parts 1 are arranged opposite to each other along the length direction of the high-voltage tester, and the two ends of the high-voltage tester are respectively placed on the two support parts 1.
[0031] The support part 1 includes a column 12 and a conductive rod 11. The column 12 may be an insulating vertical rod made of insulating material, and the conductive rod 11 may be a metal horizontal rod made of iron or stainless steel.
[0032] Among them, the conductive rod 11 is arranged on the top of the column 12, and the top of the column 12 can be the end of the column 12 away from the ground or other supporting foundations. The column 12 is used to support the conductive rod 11, and the electrical appliances to be tested are set up on the conductive rod 11, and the conductive rod 11 is used to carry the electrical appliances to be tested.
[0033] Specifically, at least two columns 12 are provided, and at least two columns 12 are arranged opposite to each other along the second direction. In the embodiment of the present application, the electrical appliance to be tested is a high-voltage tester, and the high-voltage tester is set on the conductive rod 11. The second direction is the length direction of the conductive rod 11. For example, two, three, or four columns 12 are provided. It should be noted that when two columns 12 are provided, the two columns 12 are arranged opposite to each other along the length direction of the conductive rod 11, and the two ends of the conductive rod 11 are respectively connected to the two columns 12; when multiple columns 12 are provided, the multiple columns 12 are evenly arranged along the length direction of the conductive rod 11, so as to improve the weighing capacity of the support rod.
[0034] In some possible implementations provided in this application, see Figure 1 As shown, a U-shaped clip 2 is provided on the conductive rod 11 , and the end of the electrical appliance to be tested is arranged in the U-shaped clip 2 . The U-shaped clip 2 is used to limit the electrical appliance to be tested in the length direction of the conductive rod 11 .
[0035] The U-shaped clip 2 may be made of iron or stainless steel. The U-shaped clip 2 is disposed on the surface of the conductive rod 11 on the side away from the column 12 . The U-shaped clip 2 is relatively fixed to the conductive rod 11 .
[0036] Among them, as one embodiment, the opening of the clamping mouth of the U-shaped clamp 2 is facing the vertical upward direction. When the end of the electrical appliance to be tested is placed in the clamping mouth of the U-shaped clamp 2, the U-shaped clamp 2 can limit the electrical appliance to be tested in the length direction of the conductive rod 11, so as to prevent the electrical appliance to be tested from moving along the length direction of the conductive rod 11 after being placed on the conductive rod 11; as another embodiment, the opening of the clamping mouth of the U-shaped clamp 2 is facing the vertical upward direction. When the end of the electrical appliance to be tested is placed in the clamping mouth of the U-shaped clamp 2, the U-shaped clamp 2 can limit the electrical appliance to be tested in the length direction of the conductive rod 11 on the one hand, and can limit the conductive rod 11 in the vertical upward direction on the other hand, so as to fix the electrical appliance to be tested on the conductive rod 11.
[0037] Specifically, in the embodiment of the present application, the opening of the clamping mouth of the U-shaped clamp 2 faces vertically upward, which can facilitate the placement and removal of the electrical appliance to be tested, thereby improving the test efficiency.
[0038] In some possible implementations provided in this application, see Figure 1 As shown, a plurality of U-shaped clips 2 are provided, and the plurality of U-shaped clips 2 are evenly arranged along the length direction of the conductive rod 11 .
[0039] Among them, a U-shaped clip 2 is used to fix an electrical appliance to be tested. In the embodiment of the present application, a plurality of U-shaped clips 2 are evenly arranged on the conductive rod 11 along the length direction of the conductive rod 11 so that the test bracket can fix a plurality of electrical appliances to be tested, and preventive tests can be performed on a plurality of electrical appliances to be tested at the same time, thereby improving the user experience.
[0040] Specifically, a plurality of electrical appliances to be inspected are arranged in one-to-one correspondence with a plurality of U-shaped clips 2 .
[0041] In some possible implementations provided in this application, see Figure 1 As shown, two adjacent support portions 1 are provided with at least two connecting rods 3, and the at least two connecting rods 3 are arranged opposite to each other along the second direction.
[0042] The connecting rod 3 extends along the first direction, and the connecting rod 3 is arranged between the columns 12 of two adjacent supporting parts 1 .
[0043] There are at least two connecting rods 3, and the at least two connecting rods 3 are arranged in one-to-one correspondence with the at least two columns 12. In the embodiment of the present application, the at least two columns 12 are arranged relatively along the second direction, that is, the at least two connecting rods 3 are also arranged relatively along the second direction.
[0044] Specifically, the connecting rod 3 can be set at any height of the test bracket, and the two ends of the connecting rod 3 are respectively connected to two adjacent support parts 1. By setting the connecting rod 3, the weighing capacity of the test bracket can be enhanced, the stability of the test bracket can be improved, and the preventive test of the electrical appliance to be tested can be carried out normally.
[0045] In some possible implementations provided in this application, see Figure 1 As shown, the lengths of at least two connecting rods 3 are adjustable. By setting the length of the connecting rod 3 to be adjustable, the test bracket can be adapted to electrical appliances to be tested of different lengths, thereby increasing the applicable scope of the test bracket and improving the user's applicable experience.
[0046] In some possible embodiments provided in the present application, the upright column 12 and the connecting rod 3 are multi-section long rods or telescopic rods.
[0047] In the embodiment of the present application, the column 12 is a multi-section long rod. By setting the column 12 as a multi-section long rod, the height of the column 12 is adjustable, so that the height of the test bracket, that is, the height of the electrical appliance to be tested from the ground can be adjusted, so that the test bracket can adapt to different models of electrical appliances to be tested for preventive testing. It should be noted that different models of electrical appliances to be tested need to meet different height requirements from the ground.
[0048] Specifically, one end of the long rod can be set to a male port, and the other end can be set to a female port. The male port of one long rod is embedded in the female port of another long rod. Multiple long rods are assembled in sequence through the matching connection of the male and female ports, so that the height of the assembled column 12 can be adjusted, and the height of the test bracket can be adjusted to suit different models of electrical appliances to be tested.
[0049] Among them, in the embodiment of the present application, the connecting rod 3 is a telescopic rod. By setting the connecting rod 3 as a telescopic rod, the length of the connecting rod 3 can be adjusted, so that the distance between two adjacent support parts 1 can be adjusted, so that the test bracket can adapt to electrical appliances to be tested of different lengths.
[0050] Specifically, the telescopic rod includes an outer tube and an inner tube, and the inner tube is slidably arranged in the outer tube. It should be noted that the number of the inner tube is not limited to one, so as to achieve multi-stage telescopic.
[0051] In some possible implementations provided in this application, see Figure 1 As shown, the connecting rod 3 is marked with fixed points, which are used to determine the length adjustment amount of the connecting rod 3. By marking the fixed points representing the length of the connecting rod 3 on the connecting rod 3, it is possible to replace the use of measuring tools such as a tape measure to measure the distance between two adjacent support parts 1, thereby reducing the test preparation time and improving the test efficiency.
[0052] Among them, a plurality of fixing points are arranged on the connecting rod 3 , and the plurality of fixing points are evenly arranged along the length direction of the connecting rod 3 .
[0053] Specifically, in the embodiment of the present application, the connecting rod 3 is a telescopic rod, and the connecting rod 3 includes an outer tube and a plurality of inner tubes, and a plurality of fixed points are arranged on the plurality of inner tubes in a one-to-one correspondence. It should be noted that when the inner tube slides into the outer tube, the fixed points are hidden, and the length of the connecting rod 3 can be determined by judging the number of fixed points on the connecting rod 3.
[0054] In some possible implementations provided in this application, see Figure 1 As shown, a base 4 is provided at one end of the column 12 away from the conductive rod 11, and the base 4 is a planar structure.
[0055] The columns 12 are arranged on a supporting base, and the supporting base may be the ground or the like.
[0056] Specifically, a base 4 is provided at one end of the column 12 close to the supporting foundation. The base 4 is a planar structure. By providing the base 4, the contact area between the column 12 and the supporting foundation can be increased, thereby improving the stability of the test bracket.
[0057] In some possible implementations provided in this application, see Figure 2 As shown, a leg 5 and a universal wheel 6 are provided on the side of the base 4 away from the column 12, the leg 5 is relatively fixed to the base 4, and the universal wheel 6 is escalably arranged on the base 4 through an actuator 7. The leg 5 cooperates with the escalable universal wheel 6 to realize rapid transfer and fixation of the test stand, thereby improving the user experience.
[0058] The actuator 7 may be a hydraulic cylinder or the like.
[0059] Specifically, when moving the test stand, the actuator 7 is started, the universal wheel 6 is lowered, and the test stand is moved by the universal wheel 6 to the location where the electrical appliance to be tested is to be subjected to preventive testing; after the movement is completed, the actuator 7 is turned off, the universal wheel 6 is retracted, and the test stand is fixed by the legs 5.
[0060] The test bracket further includes a return spring, a first end of the return spring is connected to the universal wheel 6 , and a second end of the return spring is relatively fixed to the base 4 .
[0061] Specifically, when the actuator 7 is started and the universal wheel 6 is lowered, the return spring is deformed to accumulate elastic potential energy; after the actuator 7 is closed, the accumulated elastic potential energy of the return spring is released, driving the universal wheel 6 to move toward the base 4, thereby realizing the folding of the universal wheel 6.
[0062] In some possible embodiments provided in the present application, the pillar 12 is made of polyamide.
[0063] Among them, in the embodiment of the present application, the column 12 is a nylon rod, which is light in weight, has high mechanical strength, good wear resistance, strong corrosion resistance, and also has a certain shock absorption and noise absorption effect.
[0064] Working principle: First, start the actuator 7, put down the universal wheel 6, and drive the test bracket to move to the location where the electrical appliance to be tested is to be tested for preventive testing through the universal wheel 6. After the movement is completed, turn off the actuator 7 to retract the universal wheel 6, and fix the test bracket through the legs 5; then adjust the height of the column 12 and the length of the connecting rod 3 so that the test bracket can match the electrical appliance to be tested for preventive testing; finally, place the electrical appliance to be tested on two adjacent support parts 1, and put the end of the electrical appliance to be tested into the clamping mouth of the U-shaped clamp 2.
[0065] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.
[0066] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
