Description

Technical Field

[0001] This utility model relates to the field of electroscope technology, specifically a foldable, insulated, telescopic electroscope. Background Technology

[0002] An electroscope is an electrostatic experimental instrument used to detect whether an object is charged and to determine the nature of the charge. It is widely used in physics teaching, laboratory testing, and industrial electrostatic monitoring.

[0003] Traditional electroscopes typically consist of a metal ball (or metal disc), a metal rod, metal foil, and an insulating shell. Their working principle is based on electrostatic induction and the repulsion effect of like charges. When a charged object comes into contact with or approaches the electroscope, the charge is conducted to the metal foil, causing it to open due to repulsive force, thus indicating the presence and nature of the charge.

[0004] However, existing electroscopes still have the following shortcomings during operation: the metal foil and guide rod of traditional electroscopes are usually fixed, and the overall position can only be adjusted manually to adapt to different detection angles. In actual use, if the position or angle of the object to be tested changes, such as irregular surfaces or narrow spaces, the operator needs to frequently adjust the overall posture of the electroscope, which reduces detection efficiency and increases the difficulty of operation.

[0005] Therefore, an improved insulation expansion detector is needed. Utility Model Content

[0006] The purpose of this invention is to provide a foldable, insulated, telescopic detector to solve the problems raised in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a foldable, insulated, telescopic voltage detector, comprising: a telescopic unit, which includes an outer telescopic sleeve rod, an inner telescopic sleeve rod fitted inside the outer telescopic sleeve rod, a transmission unit connected to the top of the inner telescopic sleeve rod, a voltage detection unit connected to the transmission unit, a protective unit fixed to the front of the outer telescopic sleeve rod, a rotating unit penetrating and connected to the outer telescopic sleeve rod and the inner telescopic sleeve rod, and a transmission component mounted on the transmission unit and connected to the rotating unit; the rotating unit includes a lower sleeve connected to the outer telescopic sleeve rod. An adjusting knob is located at the bottom of the outer telescopic sleeve and rotatably connected to the lower kit; an upper kit is fitted inside the lower kit and abuts the top of the inner telescopic sleeve; a transmission unit includes a mounting block abutting the top of the inner telescopic sleeve, a mounting port located at the top of the mounting block, a mounting chamber located inside the mounting block, a mounting seat connected to the mounting port and fixed to the voltage detection unit, and a transmission component abutting the mounting chamber and connected to the mounting seat; a protection unit includes a fixed seat fixed to the outer telescopic sleeve, a retaining sleeve abutting inside the fixed seat, and a pressure tongue fixed to the top of the retaining sleeve.

[0008] As a priority, the lower kit has limit ports on both sides, and the bottom of both sides of the upper kit has limit blocks that extend into the limit ports, and the limit blocks are matched with the limit ports for limiting.

[0009] As a preferred embodiment, the top of the upper assembly is connected to a rotating shaft that passes through the inner telescopic sleeve, and the lower gear is fixed to the top of the rotating shaft.

[0010] As a preferred option, the protective unit also includes a second flip shaft, with the second flip shaft connected to the fixed base and mounted on both sides of the sleeve, and a torsion spring fitted on the second flip shaft.

[0011] As a preferred embodiment, the lower half of the outer telescopic sleeve is fitted with a rubber sleeve, the bottom of the lower sleeve is rotatably connected to the outer telescopic sleeve, and the top of the upper sleeve is rotatably connected to the inner telescopic sleeve.

[0012] As a preferred embodiment, the transmission component consists of a first rotating shaft, a lower gear, and an upper gear. The first rotating shaft is installed between the mounting chamber and the mounting port. The lower gear is installed at the top of the rotating shaft. The upper gear is fixedly installed on the first rotating shaft, and the upper gear and the lower gear mesh with each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Through the transmission unit and the rotating unit, the voltage detector can not only perform voltage detection operations by extension and retraction, but also adjust the angle of the voltage detector unit in real time during the extension phase, so that the voltage detector unit can cope with voltage detection operations at multiple angles, reducing the limitations during voltage detection, and can be folded in non-operational periods, with the contact head of the voltage detector unit folded inward.

[0015] The protective unit can be connected to the voltage detection unit in its folded state, allowing the contact head of the voltage detection unit in the folded state to be retracted, thus providing built-in protection and ensuring that it will not be damaged during non-operational periods.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example: This utility model provides a technical solution for a foldable, insulated, telescopic electroscope, such as... Figures 1-7 As shown, it includes: a telescopic unit 500, which includes an outer telescopic sleeve 501, an inner telescopic sleeve 502 fitted inside the outer telescopic sleeve 501, a transmission unit 200 connected to the top of the inner telescopic sleeve 502, an electrical detection unit 300 connected to the transmission unit 200, a protective unit 400 fixed to the front of the outer telescopic sleeve 501, a rotating unit 100 penetrating and connected to the outer telescopic sleeve 501 and the inner telescopic sleeve 502, and a transmission component installed on the transmission unit 200 and connected to the rotating unit 100;

[0031] In the above scheme:

[0032] The telescopic unit 500 enables the voltage detection unit 300 to extend and retract during daily operation, thereby meeting actual voltage detection needs. The voltage detection unit 300 consists of a voltage detection body and voltage detection metal contacts, which are also existing components and will not be elaborated on here.

[0033] The transmission unit 200 and the rotating unit 100 enable the voltage detector to perform voltage detection operations not only by extending and retracting, but also by adjusting the angle of the voltage detector unit 300 in real time during the extension phase. This allows the voltage detector unit to handle voltage detection operations at multiple angles, reducing limitations during voltage detection. Furthermore, it can be folded during non-operation periods, with the contact head of the voltage detector unit 300 folded inward.

[0034] The protective unit 400 can be connected to the voltage detection unit 300 in the folded state, so as to retract the contact head of the voltage detection unit in the folded state, thereby achieving built-in protection and ensuring that it will not be damaged during non-operation periods.

[0035] The rotating unit 100 includes a lower sleeve 102 that is connected to the outer telescopic sleeve 501, an adjusting knob 101 that is located at the bottom of the outer telescopic sleeve 501 and rotatably connected to the lower sleeve 102, and an upper sleeve 103 that is fitted inside the lower sleeve 102 and connected to the top of the inner telescopic sleeve 502; the transmission unit 200 includes a mounting block 201 that is connected to the top of the inner telescopic sleeve 502, a mounting opening 2012 located at the top of the mounting block 201, a mounting chamber 2011 located inside the mounting block 201, a mounting seat 202 that is connected to the mounting opening 2012 and fixed to the voltage detection unit 300, and a transmission component that is connected to the mounting chamber 2011 and connected to the mounting seat 202; the protective unit 400 includes a fixed seat 402 fixed on the outer telescopic sleeve 501, a retaining sleeve 401 connected to the fixed seat 402, and a pressure tongue 403 fixed to the top of the retaining sleeve 401.

[0036] During daily work:

[0037] Personnel can adjust the voltage testing length of the voltage testing unit 300 by telescopically coordinating the outer telescopic sleeve 501 and the inner telescopic sleeve 502 to achieve the required voltage testing distance. The telescopic movement of the outer and inner telescopic sleeves 501 and 502 simultaneously extends and retracts the lower and upper components 102 and 103. When the voltage testing angle needs adjustment, personnel can rotate the adjustment knob 101, which simultaneously rotates the lower and upper components 102 within the telescopic sleeves. The transmission mechanism within the installation chamber 2011 drives the mounting base 202, causing it to flip and adjust, thus adjusting the angle of the voltage testing unit 300. When the voltage detector 300 is out of operation, it can be retracted according to the above steps. When the telescopic sleeve is retracted to its minimum, the voltage detector 300 is flipped downwards. At the same time, the voltage detector 300 presses down the pressure tongue 403, causing the retaining sleeve 401 to flip upwards. In this way, the upward-flipped retaining sleeve 401 and the downward-flipped voltage detector 300 are connected, causing the contact head on the voltage detector 300 to be inserted into the retaining sleeve 401, completing the internal protection. The voltage detector 300 refers to the main body of the voltage detector, and its end is equipped with a metal contact head for detection. In use, the contact head can be manually detached from the retaining sleeve 401. The voltage detector 300 model can be GD-35.

[0038] like Figures 1-7 As shown, in order to allow the lower kit 102 and the upper kit 103 to extend and rotate, the lower kit 102 is provided with limit ports 1021 on both sides, and the bottom of both sides of the upper kit 103 is fixedly installed with limit blocks 105 extending into the limit ports 1021, and the limit blocks 105 are matched with the limit ports 1021 for limiting.

[0039] Specifically, the lower kit 102 and the upper kit 103 are nested together. When the electroscope is extending or retracting, the inner telescopic sleeve 502 will synchronously drive the upper kit 103 to extend, thus achieving synchronous extension and retraction of the two.

[0040] When the working angle of the voltage testing unit 300 needs to be adjusted or folded, the personnel can rotate the lower kit 102 and the upper kit 103 synchronously. At this time, the lower kit 102 will be limited by its own limiting port 1021 and the limiting port 1021 on the upper kit 103, so as to ensure that the lower kit 102 and the upper kit 103 can rotate synchronously.

[0041] like Figures 1-7As shown, in order for the kit to complete the angle adjustment of the voltage detection unit 300, the transmission component is further composed of a flip shaft 203, a lower gear 204, and an upper gear 205. The flip shaft 203 is installed between the mounting chamber 2011 and the mounting port 2012. The lower gear 204 is installed at the top of the limiting block 104. The upper gear 205 is fixedly installed on the flip shaft 203, and the upper gear 205 and the lower gear 204 mesh with each other.

[0042] The top of the upper assembly 103 is connected to a rotating shaft 104 that passes through the inner telescopic sleeve 502, and the lower gear 204 is fixed to the top of the rotating shaft 104.

[0043] Specifically, when the sleeve rotates, its top will drive the rotating shaft 104 to rotate;

[0044] During this period, the rotating shaft 104 drives the lower gear 204 to rotate. At that time, the lower gear 204 will enter the transmission state. The lower gear 204 drives the meshing upper gear 205 to rotate, causing the flipping shaft 203 to rotate, thereby driving the mounting base 202 to flip and adjust, so that the working angle of the voltage detection unit 300 can be adjusted.

[0045] like Figures 1-7 As shown, in order to enable the scraping component to complete the cleaning of the second guide cavity 2022, the protective unit 400 further includes a second flip shaft 404. The two sides of the sleeve 401 are connected to the second flip shaft 404 and connected to the fixed seat 402, and a torsion spring is fitted on the second flip shaft 404.

[0046] Specifically, when the protective unit 400 is not in operation: the flip shaft 404 is reset by the action of its own torsion spring, so that the surface of the sleeve 401 is flush with the surface of the outer telescopic sleeve 501;

[0047] When the device is retracted, the voltage testing unit presses down on the pressure tongue 403 during the folding process, causing the lower part of the sleeve 401 to fold up and align with the folded-down contact head. When the device is level, the contact head is inserted into the sleeve 401. The sleeve 401 is made of plastic. When the contact head is pressed down, the port of the sleeve 401 expands. After being inserted, the sleeve 401 completes the internal insertion of the contact head.

[0048] like Figures 1-7 As shown, in order to enable the scraping component to complete the cleaning of the second guide cavity 2022, the lower half of the outer telescopic sleeve 501 is fitted with a rubber sleeve 503, the bottom of the lower sleeve 102 is rotatably connected to the outer telescopic sleeve 501, and the top of the upper sleeve 103 is rotatably connected to the inner telescopic sleeve 502.

[0049] Specifically, during the operation, personnel can hold the bottom of the telescopic sleeve 501 through the rubber sleeve 503 to increase the insulation effect during operation;

[0050] The ends of the lower kit 102 and the upper kit 103 are rotatably connected to their respective telescopic sleeves. This ensures that there is no interference and that the telescopic sleeves can synchronously drive the upper and lower sleeves to extend and retract. The rotation of the upper and lower sleeves will not affect the working state of the telescopic sleeves.

[0051] The outer telescopic sleeve 501 and the outer telescopic sleeve 501 adopt a friction locking telescopic rod, which is fixed by friction, such as a rubber bushing. The rod body can be directly pulled to adjust, and the position can be maintained by friction after releasing.

[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
