Description

Technical Field

[0001] This utility model relates to the field of resistance tester technology, specifically a double-ended grounded loop resistance tester and its outdoor support device. Background Technology

[0002] A resistance tester is an instrument used to measure the conductivity of an object. Resistance testers are widely used in electrical safety inspections and grounding project completion acceptance. There are many types of resistance testers, including grounding resistance testers, insulation resistance testers, DC resistance meters, surface resistance testers, and loop resistance testers.

[0003] Chinese utility model patent CN208367092U, published on January 11, 2019, discloses an insulation resistance tester, belonging to the field of electronic testing devices. It aims to solve the problems of misreading readings due to the user's line of sight being off-center from the vertical display panel, or the inconvenience of bending over to read values ​​in existing insulation resistance testers. The key technical point is that a slider and a groove for the slider are provided on the bottom surface of the main body. A first connecting rod is hinged to the slider, and a second connecting rod is hinged to the other end of the first connecting rod. The end of the second connecting rod away from the first connecting rod is hinged to the bottom surface of the main body. By sliding the slider and fixing its position in the groove with a locking component, the first and second connecting rods form a V-shaped support structure on the bottom surface of the main body to support the insulation resistance tester. At this time, the display panel is tilted off-center from the vertical plane and perpendicular to the operator's line of sight, allowing readings to be read without bending over, improving the user experience and increasing testing efficiency.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the existing support devices can only be used on the ground. By adjusting the support devices, stable support can be achieved even on uneven ground. At the same time, the pitch angle of the loop resistance tester can be adjusted, making it more convenient to operate the loop resistance tester. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that existing support devices can only be used on the ground. This invention aims to provide a double-grounded loop resistance tester and its outdoor support device by adjusting the support device to achieve stable support on uneven ground and adjusting the pitch angle of the loop resistance tester to make operation of the loop resistance tester more convenient.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] The present invention relates to a double-ended grounding loop resistance tester and its outdoor support device, comprising a base for placing the resistance tester; a first support rod and a second support rod are symmetrically and rotatably connected to the lower end of the base; a second slider is rotatably connected to the lower end of the first support rod; a first slider is rotatably connected to the lower end of the second support rod; and a support shaft is damped and slidably inserted into the second slider and the first slider.

[0008] Furthermore, a second fastener is threadedly connected to the upper end of the support shaft; a synchronization plate is sleeved on the second fastener.

[0009] Furthermore, a double-ended grounding loop resistance tester includes any of the outdoor support devices described above.

[0010] The present invention provides a double-ended grounding loop resistance tester and its outdoor support device, which have the following beneficial effects:

[0011] 1. This utility model fixes the support shaft by inserting it into the soil, and then adjusts the height of the second slider and the first slider on the support shaft, thereby changing the height and angle of the first support rod and the second support rod, thus changing the pitch angle and height of the resistance tester and the base. This makes it more convenient and easier to operate the resistance tester in normal squatting and sitting postures, and realizes the function of fixing and adjusting the pitch angle and height of the resistance tester on different uneven ground.

[0012] 2. This utility model uses a synchronous plate to make the two support shafts move parallel and synchronously. After being inserted into the soil, the support strength is higher and the connection with the soil is more stable. It can be fixed anywhere when used outdoors, and there is no requirement for a 90-degree tilt angle, making it more convenient and faster to insert into the soil. Attached Figure Description

[0018] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0021] Please see Figure 1-3 As shown, a double-ended grounding loop resistance tester and its outdoor support device include a base 1 for placing the resistance tester; a first support rod 2 and a second support rod 3 are symmetrically and rotatably connected to the lower end of the base 1; a second slider 4 is rotatably connected to the lower end of the first support rod 2; a first slider 5 is rotatably connected to the lower end of the second support rod 3; a support shaft 7 is damped and slidably inserted into the second slider 4 and the first slider 5. By inserting the support shaft 7 into the soil for fixation, and then adjusting the height of the second slider 4 and the first slider 5 on the support shaft 7, the height and angle of the first support rod 2 and the second support rod 3 are changed, thereby changing the pitch angle and height of the resistance tester and the base 1. This makes it more convenient and easier to operate the resistance tester in normal squatting and sitting postures, and realizes the function of fixing and adjusting the pitch angle and height of the resistance tester to adapt to different uneven ground.

[0022] The upper end of the support shaft 7 is threaded with a second fastener 9; a synchronization plate 10 is sleeved on the second fastener 9, which makes the two support shafts 7 move in parallel and synchronously. After being inserted into the soil, the support strength is higher and the connection to the soil is more stable, making it easy to fix in any place when used outdoors, and there is no requirement for a 90-degree pitch angle, making it more convenient and faster to insert into the soil.

[0023] The second slider 4 and the first slider 5 are connected to the first fastener 6 by the threaded connection of the corresponding support shaft 7. By rotating the first fastener 6 in both directions, the friction between the first fastener 6 and the support shaft 7 can be changed, thereby fixing the second slider 4 and the first slider 5 on the support shaft 7. The vertical position can also be adjusted, thereby adjusting the pitch angle and vertical height of the base 1, and thus adjusting the angle and height of the resistance tester facing the operator. This makes it easy to operate the resistance tester and provides a more stable fixation.

[0024] The lower end of the support shaft 7 is fixed with a cone head 8, which makes it easier and more convenient for the support shaft 7 to be inserted into the soil due to the soil breaking of the cone head 8, reducing the insertion resistance and making the installation more convenient.

[0025] The two ends of the synchronization plate 10 are symmetrically fixed with handles 11. The two handles 11 make it easy to hold and move the plate. When the plate is fixed in the soil, the handles 11 can be used to help the support shaft 7 and the cone 8 to be inserted into the soil for fixation, which makes the fixation stronger and the operation of the resistance tester more stable.
