Description

Technical Field

[0001] The utility model relates to the technical field of electrical detection, in particular to an adjustable electrical detection device. Background Art

[0002] Electrical testing is a series of tests and measurements performed to ensure the safety, reliability and performance of electrical equipment and systems. The items of electrical testing and the required equipment vary depending on the specific application and standards. It generally includes insulation resistance testing, ground resistance testing, loop impedance testing, short-circuit current testing, etc.

[0003] When the electrical detection device in the prior art is used, it is generally necessary to use wiring to connect the electrical equipment and the detection instrument. The detection instrument is placed on the desktop. When there are many and long wirings, the staff may accidentally pull the wiring during the detection operation, which may cause the instrument to fall from the desktop, and may directly cause physical damage to the instrument, such as cracking, deformation or damage to internal parts. Such damage may make the equipment unable to work normally or even completely scrapped. If the detection instrument falls and is damaged during use, the ongoing detection task will be interrupted, which will not only affect work efficiency, but may also cause loss of detection data and affect project progress. The damaged equipment needs to be repaired or replaced, which will involve additional costs. For some high-precision detection equipment, the repair cost may be very high.

[0004] Therefore, it is necessary to design an adjustable electrical detection device to solve the above problems. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 2-5The control component includes a control cylinder 7 fixed inside the cavity 3, and the control cylinder 7 is sealed and slidably connected with a sliding plug 8 inside. One end of the sliding plug 8 is rotatably connected with a sliding rod 9, and the end of the sliding rod 9 away from the sliding plug 8 extends to the outside of the control cylinder 7, and the sliding rod 9 is sealed and slidably connected to the control cylinder 7. A threaded rod 10 is axially connected to the sliding rod 9, and the end of the threaded rod 10 away from the sliding rod 9 extends to the outside of the detector 1, and the threaded rod 10 is threadedly connected to the detector 1. A handle 14 is fixedly connected to one end of the threaded rod 10 located outside the detector 1, which is convenient for the staff to screw the threaded rod 10 and improve the detection efficiency. A connecting pipe 6 is connected to the control cylinder 7, and the connecting pipe 6 is respectively connected to all the sleeves 5. By setting the control component, the air pressure difference suction cup 4 can be adsorbed and fixed to the desktop, which can prevent the detector 1 from falling on the ground and prevent damage to the instrument.

[0026] Reference Figure 3-5 The cleaning component includes a cleaning tube 11, which is connected to the control tube 7. A plurality of jet holes 12 are provided on the inner top surface of the interface 2, and all the jet holes 12 are connected to the cleaning tube 11. The inner surface of the jet holes 12 is inclined so that the dust in the interface 2 can be blown toward the opening to ensure the effectiveness of cleaning the interface 2. The interface 2 can also be cleaned during the placement of the detector 1, which can ensure the stability of the connection between the wiring and the interface 2 and improve the accuracy of the detection data.

[0027] The specific working principle of the utility model is as follows:

[0028] During electrical testing, the staff places the detector 1 on the desktop. At this time, under the action of gravity, the bottom of the connecting block 13 is in contact with the inner bottom surface of the sleeve 5. Then the staff rotates the threaded rod 10 through the handle 14, thereby driving the sliding rod 9 to rotate and move, so that the sliding plug 8 can move. The movement of the sliding plug 8 causes a negative pressure state on one side. At this time, the air between the suction cup 4 and the desktop can be sucked into the control cylinder 7 through the connecting tube 6. At this time, the suction cup 4 and the desktop are fixed to each other through the air pressure difference. In this way, when the staff accidentally pulls the wiring, it will not cause the detector 1 to It is worth mentioning that after the suction cup 4 is fixed to the desktop, if one side or the whole detector 1 moves upward, the connecting block 13 will also move upward. The upward movement of the connecting block 13 will further suck the air between the suction cup 4 and the desktop into the sleeve 5, so that the suction cup 4 and the desktop are fixed more stably, and it is difficult to separate the whole device from the desktop, which further improves the stability of the detector 1 and prevents the staff from arbitrarily adjusting the position of the device after the connection, thereby affecting the connectivity between the device and the electrical equipment.

[0029] Furthermore, in the above process, while the sliding plug 8 moves to allow the air in the suction cup 4 to enter the control tube 7, the air on the other side of the sliding plug 8 will be squeezed into the cleaning tube 11 and then ejected through the jet hole 12, thereby blowing away the dust and the like adhering to the interface 2, ensuring the cleanliness of the inside of the interface 2, and thus ensuring the stability of transmission after the wiring is connected to the interface 2.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
