[0001] The utility model relates to a kind of electroscope with telescopic insulating operating pole. BACKGROUND

[0002] Electroscope is a kind of instrument to detect whether object is electrified and roughly estimate the size of electrification, and electroscope is generally divided into high-voltage electroscope and low-voltage electroscope, wherein low-voltage electroscope is generally used to test low-voltage electrical equipment with ground voltage below 1000V, and high-voltage electroscope is mainly used to test high-voltage electrical equipment with ground voltage above 1000V, and operation monitoring system is generally executed when electroscope is used, and one person is generally operated and one person is generally monitored to ensure the safety of electroscope use.

[0003] The existing electroscope is generally installed on telescopic rod to make the length of electroscope adjustable to realize electrification of higher objects in order to facilitate users to electrify higher objects during use, and electroscope is generally installed by clamping during installation, and although such installation method is relatively simple and convenient, it is easy to cause telescopic rod to self-extend to cause electroscope to accidentally extend and collide with external objects due to swinging during carrying of electroscope after telescopic rod is stored. SUMMARY

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides an electroscope with telescopic insulating operating rod, which realizes the limiting of the position of electroscope body after telescopic rod is retracted by adding positioning mechanism to solve the problems raised in the above background technology.

[0005] The technical solution for achieving the purpose of the utility model is as follows: an electroscope with telescopic insulating operating rod, comprising an insulating sleeve, a plurality of anti-skid rings are arranged on the outer wall of the insulating sleeve and are uniformly distributed, a telescopic rod is arranged in the insulating sleeve, an electroscope body is arranged at the top of the telescopic rod, and a positioning mechanism is arranged between the electroscope body and the telescopic rod.

[0006] In a preferred embodiment, the positioning mechanism comprises a fixing ring, a support rod is arranged at the top of the fixing ring, an arc-shaped clamping plate is arranged at the top of the support rod, an L-shaped connecting rod is arranged at the top of the arc-shaped clamping plate, and a connecting ring is arranged on the side of the horizontal segment of the L-shaped connecting rod away from the vertical segment.

[0007] In a preferred embodiment, a connecting plate is fixedly arranged at the top of the vertical segment of the L-shaped connecting rod, a first clamping groove is formed in the bottom of the connecting plate, a first clamping block is arranged in the first clamping groove, and the bottom of the first clamping block is connected with the telescopic rod through the connecting ring.

[0008] In a preferred embodiment, the other side of the fixed ring top is provided with a support plate, the top of the support plate is connected to a movable plate by hinging, the movable plate can rotate freely around the hinge point in a plane perpendicular to the axial direction of the telescopic rod, and a second clamping block is arranged at the bottom of the movable plate close to the end in contact with the connecting plate.

[0009] In a preferred embodiment, the side of the connecting plate in contact with the second clamping block is provided with a second clamping groove at a position corresponding to the second clamping block, the shape and size of the clamping groove are matched with the second clamping block, so that the second clamping block can be tightly clamped, and a positioning groove is arranged on the side of the connecting plate close to the second clamping groove in the horizontal direction, and a positioning block is arranged inside the positioning groove, the positioning block can slide in the positioning groove, so as to further limit the position of the second clamping block in the second clamping groove and enhance the positioning effect.

[0010] In a preferred embodiment, the insulating sleeve and the plurality of anti-skid rings are made of rubber material.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. Avoid accidental telescopic collision: the utility model is provided with a positioning mechanism, which can effectively limit the position of the electric tester body after the telescopic rod of the electric tester body is retracted. During the carrying process, the ordinary electric tester may cause the telescopic rod to automatically extend and retract, and thus the electric tester collides with external objects. The positioning mechanism of the device can prevent this from happening, effectively protect the electric tester body and the telescopic rod, reduce the damage risk caused by collision, and improve the safety of the device during the carrying process.

[0013] 2. Double positioning and firm limiting: the positioning mechanism adopts double positioning design. First positioning, the first clamping block (10) and the first clamping groove at the bottom of the connecting plate (9) are tightly matched, the connecting plate (9) is stably connected to the telescopic rod (3), the position of the electric tester body (4) is preliminarily determined, and the electric tester body (4) will not shake randomly in general. Second positioning, the second clamping block (13) at the bottom of the movable plate (12) is precisely clamped with the second clamping groove on the connecting plate (9), and the position of the connecting plate (9) is limited again from another direction and level. This double positioning method can constrain the electric tester body (4) from different angles, and compared with the traditional single positioning method, the stability of the limiting is greatly improved. Whether it is normal handheld carrying or in the process of relatively bumpy transportation, the electric tester body (4) can be effectively prevented from displacement and shaking.

[0014] 3. Convenient operation: The positioning mechanism fully considers the convenience of the user in design. Its structure and operation mode are carefully optimized, and the user can easily operate the positioning mechanism without complex operation steps or the help of additional tools. Whether it is to start the positioning function to fix the retracted electroscope body or to release the positioning to normally use the electroscope, it can be quickly and conveniently completed, greatly saving the user's time and effort.

[0015] 4. Improve practicality: In summary, the positioning mechanism not only protects the electroscope from being damaged during carrying, but also has firm limiting and convenient operation performance. This makes the user more confident and efficient in daily carrying and using the electroscope, without worrying about various problems during carrying, meeting the needs of various actual uses, and significantly improving the overall practicality of the device.
