Description

Technical Field

[0001] This application relates to the field of equipotential testing instruments, and more particularly to an equipotential testing instrument. Background Technology

[0002] The equipotential bonding tester, using the precision four-wire method, is a specialized instrument for testing the equipotential bonding quality between metal components in buildings (such as lightning protection strips, ground beams, structures, protective structures, floor slab reinforcement, water pipes, radiators, bathrooms, doors and windows, balconies, kitchens, etc.). It can also measure the resistance of the connecting conductors between various electrical equipment and the grounding grid, as well as the contact resistance of circuit breakers, switches, socket contacts, and various coil resistances, shunt resistances, metal riveting resistances in vehicles, ships, and aircraft, resistances of electric welding points, parallel connection resistances of batteries, and resistances of distribution panel busbars and conductor connections.

[0003] Existing equipotential testing instruments lack internal cable management devices and cannot effectively accommodate users. They also lack a linkage mechanism for opening and closing and are limited in dim environments, making them inconvenient to use. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides an equipotential tester that overcomes the deficiencies of the prior art. It aims to solve the problems that existing equipotential testers lack internal cable management devices, cannot effectively accommodate users, lack linkage mechanisms for opening and closing, and are limited in dim environments, making them inconvenient to use.

[0005] To achieve the above objectives, this application provides the following technical solution: an equipotential testing instrument, comprising a housing, a top cover hinged to the top of the housing, a testing instrument body disposed inside the housing, a display screen and control buttons disposed on the top of the testing instrument body, a connection interface and a probe disposed on one side of the testing instrument body, the connection interface and the probe being connected by a wire, and a linkage mechanism disposed on both sides of the testing instrument body, the linkage mechanism comprising two sets of fixing plates and two sets of connecting plates, the two sets of fixing plates and the connecting plates being located on both sides of the linkage mechanism, the two sets of fixing plates being rotatably connected to the testing instrument body, the two sets of connecting plates being fixedly connected to the testing instrument body, the connecting plates having a sliding groove disposed inside, and a connecting rod being slidably connected inside each of the two sets of sliding grooves, the other end of the connecting rod being hinged to the bottom of the top cover.

[0006] By adopting the above technical solution and setting up a linkage mechanism, when the operator opens the top cover, the connecting rod will move. At this time, the bottom end of the connecting rod will slide inside the slide groove. After sliding to one end, it will cooperate with the fixed plate to lift one end of the tester body directly inside the shell. Then, the operator can operate the device through the display screen and control buttons. This setting can achieve a linkage effect between the top cover and the tester body. When the top cover is opened, the tester body can be lifted and tilted inside the shell, making it more convenient for the operator to use and improving the practicality of the device.

[0007] As a preferred technical solution of this application, two sets of wire take-up devices are provided on the upper side of the tester body. Each set of wire take-up devices includes a fixed plate, and a wire threading frame is rotatably connected between the two sets of fixed plates. A rotating block is fixedly connected to the top of the wire threading frame.

[0008] By adopting the above technical solution and setting up a wire take-up device, the wire bundle can be passed through the inside of the wire puller first, and then the wire puller can be rotated by rotating the rotating block to quickly collect the wire bundle. This can effectively reduce the phenomenon of wire bundles getting tangled inside the casing and improve the practicality of the device.

[0009] As a preferred technical solution of this application, a locking block is provided on the front of the top cover, and a first fixing block is provided on the front of the outer shell, with a rotating rod rotatably connected to the outside of the first fixing block.

[0010] By adopting the above technical solution and setting a locking block, the overall airtightness can be improved when the device is closed, and it is also more convenient to open it later.

[0011] As a preferred technical solution of this application, the wire threading frame is provided with a second fixing block inside, and the second fixing block has multiple sets of wire threading holes inside.

[0012] By adopting the above technical solution, the fixed block can further fix the wire harness and can pass through multiple wire harnesses, thus enabling the collection of multiple wire harnesses.

[0013] As a preferred technical solution of this application, a battery compartment is provided on one side of the tester body, a battery cover is provided on the outside of the battery compartment, and a connecting bolt is provided on one side of the battery cover.

[0014] By adopting the above technical solution and setting up a battery compartment, the battery can be replaced quickly, ensuring that it will not affect the normal use of the device.

[0015] As a preferred technical solution of this application, a lighting lamp is provided at the bottom of the top cover, and the lighting lamp is electrically connected to the tester body.

[0016] By adopting the above technical solution and installing lighting, the device can be illuminated in dim environments, thus improving its adaptability to the environment.

[0017] As a preferred embodiment of this application, the top of the cover is provided with a handle.

[0018] By adopting the above technical solution and by setting a handle, the device can be quickly lifted during use, making it more convenient to pick up.

[0019] As a preferred technical solution of this application, four sets of stabilizing pads are provided at the bottom of the shell, and the four sets of stabilizing pads are located at the four corners of the bottom of the shell.

[0020] By adopting the above technical solution and setting a stabilizing pad, the overall stability during use can be improved, thus enhancing the practicality of the device.

[0021] The beneficial effects of this application are: 1. By setting up a linkage mechanism, when the operator opens the top cover, the connecting rod will move. At this time, the bottom end of the connecting rod will slide inside the slide groove. After sliding to one end, it will cooperate with the fixed plate to lift one end of the tester body directly inside the shell. Then, the operator can operate the device through the display screen and control buttons. This setting can realize the linkage effect between the top cover and the tester body. When the top cover is opened, the tester body can be lifted and tilted inside the shell, making it more convenient for the operator to use and improving the practicality of the device.

[0022] 2. By setting up a wire take-up device, during use, the wire bundle can be first passed through the inside of the wire puller, and then the wire puller can be rotated by rotating the rotating block to quickly collect the wire bundle. This can effectively reduce the phenomenon of wire bundles getting tangled inside the casing and improve the practicality of the device. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Reference Figure 1-4 An equipotential testing instrument includes a housing 1, a top cover 2 hinged to the top of the housing 1, a testing instrument body 3 disposed inside the housing 1, a display screen 301 and control buttons 302 disposed on the top of the testing instrument body 3, a connection interface 303 and a probe 304 disposed on one side of the testing instrument body 3, the connection interface 303 and the probe 304 being connected by a wire, and a linkage mechanism 5 disposed on both sides of the testing instrument body 3, the linkage mechanism 5 including two sets of fixing plates 501 and two sets of connecting plates 502, the two sets of fixing plates 501 and the connecting plates 502 being located on both sides of the linkage mechanism 5, the two sets of fixing plates 501 being rotatably connected to the testing instrument body 3, the two sets of connecting plates 502 being fixedly connected to the testing instrument body 3, the connecting plates 502 being provided with a sliding groove 503 inside, and a connecting rod 504 being slidably connected inside each of the two sets of sliding grooves 503, the other end of the connecting rod 504 being hinged to the bottom of the top cover 2. The top cover 2 has a locking block 202 on its front side, and the outer shell 1 has a first fixing block 6 on its front side. The first fixing block 6 is rotatably connected to a rotating rod 601.

[0027] By setting up the linkage mechanism 5, when the operator opens the top cover 2, the connecting rod 504 will move. At this time, the bottom end of the connecting rod 504 will slide inside the slide groove 503. After sliding to one end, it will cooperate with the fixing plate 501, directly lifting one end of the tester body 3 inside the outer shell 1. Then, the operator can operate the device through the display screen 301 and the control button 302. This setting can achieve a linkage effect between the top cover 2 and the tester body 3. Opening the top cover 2 can lift the tester body 3, making it tilted inside the outer shell 1, which is more convenient for the operator to use and improves the practicality of the device. By setting up the locking block 202, the overall airtightness can be improved when the device is closed during use, and it is also more convenient to open it later.

[0028] Reference Figure 1-4 Two sets of wire take-up devices 4 are provided on one side of the upper part of the tester body 3. Each set of wire take-up devices 4 includes a fixed plate 401. A wire threading frame 402 is rotatably connected between the two sets of fixed plates 401. A rotating block 403 is fixedly connected to the top of the wire threading frame 402. A second fixed block 405 is provided inside the wire threading frame 402. Multiple sets of wire threading holes 406 are opened inside the second fixed block 405. An illumination lamp 7 is provided at the bottom of the top cover 2. The illumination lamp 7 is electrically connected to the tester body 3. By setting the wire take-up devices 4, the wire bundle can be threaded through the wire threading frame 406 before use. The wire harness is quickly collected by rotating the rotating block 403 to make the wire harness 402 rotate inside the wire harness holder 402. This effectively reduces the possibility of wire harnesses getting tangled inside the outer casing 1 and improves the practicality of the device. The second fixing block 405 can further fix the wire harness and can pass through multiple sets of wire harnesses, enabling the collection of multiple sets of wire harnesses. The lighting lamp 7 can provide illumination for the use of the device in dim environments, improving its adaptability to the environment.

[0029] Reference Figure 1-4 The tester body 3 has a battery compartment 305 on one side, and a battery cover 306 is provided on the outside of the battery compartment 305. A connecting bolt 307 is provided on one side of the battery cover 306. The battery compartment 305 allows for quick battery replacement, ensuring that the normal use of the device is not affected. The top cover 2 has a handle 201 on its top. The handle 201 allows the device to be lifted quickly during use, making it more convenient to pick up. The bottom of the outer shell 1 has four sets of stabilizing pads 101, which are located at the four corners of the bottom of the outer shell 1. The stabilizing pads 101 improve the overall stability when placed, enhancing the practicality of the device.

[0030] Working principle: By setting up the linkage mechanism 5, when the operator opens the top cover 2, it will drive the connecting rod 504 to move. At this time, the bottom end of the connecting rod 504 will slide inside the slide groove 503. After sliding to one end, it will cooperate with the fixing plate 501 to lift one end of the tester body 3 inside the outer shell 1. Then the operator can operate the device through the display screen 301 and the control button 302. This setting can realize the linkage effect between the top cover 2 and the tester body 3. When the top cover 2 is opened, the tester body 3 can be lifted and tilted inside the outer shell 1, making it more convenient for the operator to use and improving the practicality of the device. By setting up the wire take-up device 4, when in use, the wire harness can be passed through the wire puller 402 first. Then, by rotating the rotating block 403, the wire puller 402 can be rotated to quickly collect the wire harness. This can effectively reduce the phenomenon of wire harnesses tangling inside the outer shell 1 and improve the practicality of the device. Among them, by setting the card block 202, the overall airtightness can be improved when the device is closed during use, and it is more convenient to open it later. The second fixing block 405 can further fix the wire harness and can pass through multiple wire harnesses, enabling the collection of multiple wire harnesses. Meanwhile, by setting up the battery compartment 305, the battery can be replaced quickly, ensuring that it will not affect the normal use of the device. In addition, by setting up the lighting lamp 7, the device can be illuminated in dim environments, improving its adaptability to the environment; by setting up the handle 201, the device can be quickly lifted during use, making it more convenient to pick up; by setting up the stabilizing pad 101, the overall stability when placed during use can be improved, enhancing the practicality of the device.
