Description

Technical Field

[0001] The invention relates to the technical field of experimental connection rods, in particular to a multifunctional experimental connection rod and a use method thereof. Background Art

[0002] The experimental wiring rod is a tool specially designed for connecting wires in an experimental environment. It is mainly used for testing or maintenance when there is no direct access to electrical equipment, thus avoiding the high-risk operation of operators climbing to connect. In high-voltage electrical experiments, the experimental wiring rod is used to connect the grounding terminal of the electrical equipment to the ground to ensure the safety of people and equipment; when testing or repairing electrical equipment that cannot be directly contacted, the experimental wiring rod can conveniently perform temporary wiring operations; in the laboratory, the experimental wiring rod is often used to connect various experimental equipment for circuit testing, signal transmission and other experimental activities. In summary, the experimental wiring rod is a very important tool in the experimental environment. It can not only improve the safety and efficiency of wiring operations, but also meet various complex wiring needs.

[0003] The Chinese patent publication number is CN201548642U, which discloses a high-voltage test wiring rod, which includes a telescopic or segmented insulating rod, and a metal hook is connected to the end of the insulating rod. By connecting a metal hook to the upper end of the existing insulating rod commonly used by electricians, when doing preventive experiments on high-altitude electrical equipment, the metal hook connected with the test wiring can be directly connected to the high-altitude electrical equipment to complete the high-altitude wiring work. Compared with aerial work vehicles and aerial wiring pliers, it has the advantages of simple and fast high-altitude wiring, low cost, high wiring efficiency, etc., and can also avoid the risks brought by personnel climbing operations. A threaded joint is provided at the end of the insulating rod, and a thread matching the threaded joint is provided on the metal hook. Such a setting facilitates the installation and disassembly of the metal hook, and after the metal hook is removed, it will not affect the application of the insulating rod in other electrical fields.

[0004] The above-mentioned prior art solution has the following defects: it realizes flexible connection between multiple insulating rods through threads, but as the use time of the threaded connecting rod increases, the threads in the threaded connector may gradually lose their original shape and size due to wear, resulting in thread slippage, or when installing or disassembling the threaded connector, excessive force or excessive deviation may cause the threads to be worn due to excessive force, thereby causing thread slippage. Thread slippage will cause unstable connection between the insulating rods, affecting the test effect. Therefore, we propose a multifunctional experimental connecting rod and its use method to solve the above-mentioned problems. Summary of the invention

At this time, press the push rod 21. When the thrust is greater than the elastic force of the second compression spring 22, the push rod 21 moves into the push rod groove 20. Due to the inclined setting of one end of the push rod 21 and the inclined lower end of the sliding rod 19 It is arranged that when the push rod 21 is pushed inward, the sliding rod 19 is prompted to slide upward in the sliding rod groove 12, and the sliding rod 19 that slides upward pushes the limiting rod 15 to slide outward in the first limiting rod groove 13 through the inclined angle of its upper end, until the limiting rod 15 enters the inside of the second limiting rod groove 14, and at this time, the locking plate 25 is pressed downward, and the locking plate 25 slides to the inside of the pushing rod groove 20 under the limitation of the locking plate sliding groove 24 and is placed on the front side of the pushing rod 21, thereby limiting the pushing rod 21 to prevent the pushing rod 21 from retracting;

[0036] Step 2: At the same time, the above steps connect the second rod body 3 and the first connection end 7 and the second connection end 8 of the support mechanism 4, then separate the three support telescopic rods 9 at the lower end of the support mechanism 4, adjust the angle between the support telescopic rod 9 and the fixed plate 26 and lock it, adjust the length of the support telescopic rod 9 until the level 28 on the front side of the fixed plate 26 remains horizontal, and the support telescopic rod 9 is rotatably connected to the support foot 10 through the ball shaft 29, so that the three support feet 10 can fit the ground at different inclination angles;

[0037] Step three: When conducting test wiring after the connection is completed, connect the wire clamping mechanism 6 to the electrical equipment to be tested, place the electrical equipment to be connected between the clamping grooves 35, start the drive screw 31, and drive the two sliding blocks 32 to approach each other, thereby driving the two clamping blocks 34 to approach each other, so that the clamping blocks 34 can clamp the electrical equipment for high-altitude wiring.
