TECHNICAL FIELD

[0001] The application relates to the technical field of safety protection of an electroscope, and particularly relates to an anti-mis-touch safety protection sleeve of an electroscope. BACKGROUND

[0002] The electroscope is mainly used for detecting whether an object is electrified and roughly estimating the electrified quantity. In an electric power system, the electroscope plays a vital safety role, can effectively prevent electric shock accidents, and protects the life safety of workers. Meanwhile, the electroscope can also assist in electric power equipment maintenance and confirm whether the equipment has been safely powered off.

[0003] The electroscope is usually designed with an insulating handle to ensure that the operator's hands are far away from the monitoring point, but the probe part is generally exposed to facilitate contact with the detection area. If the probe part or the conductive area of the electroscope is mis-touched during operation, an electric shock accident may occur, which may endanger life, especially in a high-voltage scene. Mis-touching may also cause short circuit or arc discharge, resulting in equipment damage or fire.

[0004] Therefore, the application provides an anti-mis-touch safety protection sleeve of an electroscope to solve the above problems. CONTENT OF THE UTILITY MODEL

[0006] To achieve the above object, the application provides the following technical scheme: an anti-mis-touch safety protection sleeve of an electroscope, comprising a fixing seat for being adhesively fixed to one end of the electroscope close to a probe, and a rubber elastic sleeve sleeved outside the probe and fixedly installed at one end of the fixing seat, wherein one end of the rubber elastic sleeve close to the electroscope is fixedly installed with a threaded head, and the fixing seat is rotationally connected with a lock nut screwed with the threaded head. In this way, the probe is completely isolated from the operator or external conductors through the normal coverage of the elastic sleeve, the risk of electric shock in a high-voltage scene is eliminated, and safety hazards such as short circuit and arc discharge are avoided. Meanwhile, the deformation characteristics of the rubber elastic sleeve allow the probe to be temporarily exposed during detection, do not affect the normal function and accuracy of the electroscope, and automatically reset the protection, thus balancing safety and practicability.

[0007] Preferably, the rubber elastic sleeve is arranged in a horn shape close to the electroscope.

[0008] Preferably, the rubber elastic sleeve has corrugated folding grooves on the side surface for axial compression of the rubber elastic sleeve.

[0009] Preferably, the screw head has at least three strain grooves arranged in a ring array, and the inner ring of the lock nut has a gradually decreasing inner diameter for gradually tightening the screw head as screwed with the screw head.

[0010] Preferably, the side surface of the lock nut has a plurality of friction grooves arranged in a ring array.

[0011] Preferably, the screw head has a clasp near the outer wall of one end of the rubber elastic sleeve, and the inner ring of the small-diameter end of the rubber elastic sleeve has a ring groove corresponding to the clasp.

[0012] Preferably, the rubber elastic sleeve, the fixing seat, and the lock nut are all made of PVC material, and the rubber elastic sleeve is made of transparent PVC material.

[0013] The electric tester anti-mis-touch safety protection sleeve completely isolates the probe from the operator or external conductor through the normal coverage of the elastic sleeve, eliminates the risk of electric shock in high-voltage scenarios, and avoids safety hazards such as short circuit and arc discharge. At the same time, the deformation characteristics of the rubber elastic sleeve allow the probe to be temporarily exposed during detection, without affecting the normal function and accuracy of the electric tester, and the automatic reset protection takes into account safety and practicality.

[0014] The electric tester anti-mis-touch safety protection sleeve, the rubber elastic sleeve, the screw head, and the lock nut and fixing seat are all detachable, which facilitates subsequent maintenance or replacement, thereby reducing maintenance costs. BRIEF DESCRIPTION OF DRAWINGS

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] The present embodiment provides a safety protective sleeve for preventing mistaken touch of an electroscope, as shown in the figure, the safety protective sleeve for preventing mistaken touch of the electroscope comprises a fixing seat 2 for being adhesively fixed at one end of the electroscope 1 close to a probe 11, and a rubber elastic sleeve 5 sleeved outside the probe 11 and fixedly installed at one end of the fixing seat 2, wherein the rubber elastic sleeve 5 is fixedly installed with a threaded head 4 at one end close to the electroscope 1, and the fixing seat 2 is rotationally connected with a lock nut 3 screwed with the threaded head 4. Figures 1-5

[0028] In use, the fixing seat 2 is sleeved at the root of the probe 11 of the electroscope 1 and adhesively fixed to ensure stability, and then the rubber elastic sleeve 5 is sleeved on the probe 11, at this time, the threaded head 4 on the rubber elastic sleeve 5 is aligned with the lock nut 3, the lock nut 3 is screwed with the threaded head 4 by rotating to fasten, so as to install and fix the rubber elastic sleeve 5 on the electroscope 1; in detection, the probe 11 of the electroscope 1 is close to the measured object, the rubber elastic sleeve 5 is compressed, the probe 11 contacts the target to complete the charged detection, after detection, the external force is removed, the rubber sleeve is automatically reset by relying on the elasticity, the probe 11 is re-shielded, and during the period, if the operator mistakenly touches the probe area, the insulating layer of the rubber sleeve directly isolates the current to avoid electric shock.

[0029] It should be noted that the rubber elastic sleeve 5 is arranged as a horn shape close to the electroscope 1 with a small caliber, and the rubber elastic sleeve 5 has a corrugated folding groove on the side surface for axial compression of the rubber elastic sleeve 5; the small caliber end is closely attached to the root of the probe 11 of the electroscope 1 to avoid sliding or deviation of the protective sleeve, and the large caliber distal end is expanded outward when the probe 11 contacts the measured object to provide a larger deformation space and reduce the detection resistance, and the corrugated structure enables the rubber sleeve to be folded and compressed along the corrugated groove under axial stress to reduce the deformation resistance and improve the flexibility of stretching and contraction.

[0030] ​Further, the threaded head 4 has at least three strain grooves 41 arranged in a ring array, and the inner ring of the lock nut 3 has gradually decreasing inner diameter for gradually tightening the threaded head 4 with the screwing of the threaded head 4; when the lock nut 3 is screwed, the tapered thread generates radial extrusion on the threaded head 4, and the strain grooves 41 of the threaded head are deformed under pressure, so that the outer diameter of the threaded head is reduced to tightly hold the probe root of the tester.

[0031] Further, the side surface of the lock nut 3 has a plurality of friction grooves 31 arranged in a ring array; the friction grooves 31 increase the friction between the outer surface of the lock nut and the operator's hand, facilitating manual rotation of the lock nut 3 to adjust the tightness.

[0032] Further, the threaded head 4 has a clasp 42 on the outer wall of the end close to the rubber elastic sleeve 5, and the inner ring of the small-diameter end of the rubber elastic sleeve 5 has a ring groove 51 corresponding to the clasp 42; after the clasp 42 is embedded in the ring groove 51, mechanical interlocking is formed to prevent the rubber elastic sleeve 5 from being axially separated from the threaded head 4, and the buckle connection does not require glue or bolts, reducing the assembly difficulty and cost.

[0033] It should be noted that the rubber elastic sleeve 5, the fixed seat 2 and the lock nut 3 are all made of PVC material, and the rubber elastic sleeve 5 is made of transparent PVC material; the PVC insulation ensures that the protective sleeve itself is not conductive, avoiding becoming a medium for electric shock, and the PVC material is low in price and easy to process, suitable for large-scale production, and at the same time, the transparent setting of the rubber elastic sleeve 5 can directly observe the contact condition of the probe 11 and the target.

[0034] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
