Description

Technical Field

[0001] This utility model relates to the field of electrical strength testing technology, specifically to an electrical strength measuring device for insulating materials. Background Technology

[0002] Electrical strength testing, also known as withstand voltage testing, is simply a process where you check the insulation strength of electrical equipment. Every piece of electrical equipment has a certain insulation strength, which varies depending on the rated voltage. When a certain voltage level is exceeded, the insulation of the equipment will break down. Electrical strength testing checks whether applying a high voltage to the equipment under test will cause breakdown. If it doesn't break down, it passes; if it does, it fails.

[0003] In the mass production and use of materials, the general testing device is a high-voltage tester. Since multiple tools are required to work together during the testing process, general measuring and storage devices cannot classify and store various measuring instruments.

[0004] Therefore, a device for measuring the electrical strength of insulating materials is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a device for measuring the electrical strength of insulating materials, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An electrical strength measuring device for insulating materials includes an upper cabinet and a lower cabinet integrally formed therewith. The lower cabinet is provided with casters. The top of the upper cabinet has a measuring tool slot and a hinged cover therewith. The hinged cover is magnetically connected to the upper cabinet after being flipped open.

[0008] The front end of the upper cabinet is provided with an auxiliary drawer and an accessory drawer from top to bottom;

[0009] The front end of the lower cabinet is provided with a maintenance tool drawer and a strength measurement tool storage cabinet from top to bottom;

[0010] The lower cabinet is equipped with a rotation limit structure to restrict the removal of the maintenance tool drawer;

[0011] The strength measuring tool storage cabinet is equipped with double doors, and the double doors are equipped with rotating closures for closing.

[0012] Furthermore, the flip cover is connected to the upper cabinet via a hinge.

[0013] Furthermore, an upper magnetic block is installed inside the flip cover, and a lower magnetic block is installed inside the measuring tool slot.

[0014] Furthermore, the auxiliary drawer includes two separate drawers: a wide drawer and a narrow drawer.

[0015] Furthermore, the rotation limiting structure includes a limiting rod and a damping shaft. The limiting rod is connected to the lower cabinet through the damping shaft, and the limiting rod prevents the maintenance tool drawer from being pulled out after rotation.

[0016] Furthermore, the strength measuring tool storage cabinet is connected to double doors via hinges.

[0017] Furthermore, the rotating closing member consists of an L-limiting rod and a sleeve. The L-limiting rod is connected to the door body of one of the double doors through a damping rotating shaft, and the sleeve is fixed to the door body of the other double door. After the L-limiting rod rotates, its short side is inserted into the sleeve.

[0018] Furthermore, the inner diameter of the sleeve is greater than the width of the short side of the L-limiting rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This utility model adopts a design of classified drawers and cabinets, which can be used to store multiple measuring instruments, such as high voltage testers, maintenance tools, etc., to avoid tools getting mixed up.

[0021] The portable design allows the device to be moved short distances within the site, making it convenient and practical.

[0022] The design employs a rotation limit structure and a rotation closing component to restrict the opening of maintenance tool drawers and strength measuring tool storage cabinets, preventing tool loss due to accidental collapse. Attached Figure Description

[0024] Figure 2 This is a schematic diagram of the main structure of this utility model;

[0025] Figure 3 This is a side view of the structure of this utility model. Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Example 1:

[0028] Please see Figure 1-3 This utility model provides a technical solution:

[0029] An electrical strength measuring device for insulating materials includes an upper cabinet 3 and a lower cabinet 4 integrally formed therewith. The lower cabinet 4 is equipped with casters 10, which can be used to move short distances within the site, making it convenient for measurement and maintenance.

[0030] A measuring tool slot is provided at the top of the upper cabinet 3 for placing some matching measuring tools. A hinged cover 1 is also provided thereto. The cover 1 can be flipped open and closed to seal the measuring tool slot. To enhance the sealing, the cover 1 is magnetically connected to the upper cabinet 3 after being flipped open.

[0031] In order to store more tools in a categorized manner, auxiliary drawers and accessory drawers 301 are provided from top to bottom at the front end of the upper cabinet 3;

[0032] In order to store maintenance tools and high voltage testers, maintenance tool drawers 8 and strength measuring tool storage cabinets 14 are arranged sequentially from top to bottom at the front end of the lower cabinet 4. The high voltage tester and its matching tools are stored in the strength measuring tool storage cabinet 14.

[0033] To limit opening and prevent tools from scattering, the lower cabinet 4 is equipped with a rotation limit structure to restrict the pulling out of the maintenance tool drawer 8, and the strength measuring tool storage cabinet 14 is equipped with double doors 9, which are equipped with a rotating closing member for closing.

[0034] like Figure 1 As shown:

[0035] To enable the opening and closing of the flip cover 1, the flip cover 1 is connected to the upper cabinet 3 via a hinge. At the same time, an upper magnetic block 2 is installed inside the flip cover 1, and a lower magnetic block 5 is installed inside the measuring tool slot. When the flip cover 1 is closed, the upper magnetic block 2 and the lower magnetic block 5 are magnetically attracted to each other, enhancing the closure.

[0036] like Figure 2 As shown:

[0037] The auxiliary drawers include two separate drawers: a wide drawer (7) and a narrow drawer (6), which can be used to store different tools.

[0038] like Figure 3 As shown:

[0039] The rotation limit structure includes a limit rod 11 and a damping shaft. The limit rod 11 is connected to the lower cabinet 4 through the damping shaft to realize the rotation of the limit rod 11 and the limit after rotation (the limit angle is 0 degrees, 45 degrees, and 90 degrees). After rotating 90 degrees, the limit rod 11 can prevent the maintenance tool drawer 8 from being pulled out.

[0040] like Figure 3 As shown:

[0041] The strength measuring tool storage cabinet 14 is connected to the double doors 9 via hinges, allowing the double doors 9 to open and close. The rotating closing component consists of an L-limiting rod 12 and a sleeve 13. The L-limiting rod 12 is connected to the door body of one of the double doors 9 via a damping pivot, enabling the L-limiting rod 12 to rotate and be limited after rotation (its limiting angles are 0 degrees, 45 degrees, and 90 degrees). The sleeve 13 is fixed to the door body of the other double door 9, so that after the L-limiting rod 12 rotates 90 degrees, its short side is inserted into the sleeve 13. To facilitate the rotation of the L-limiting rod 12, the diameter inside the sleeve 13 is larger than the width of the short side of the L-limiting rod 12.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
