Specific details for implementing the invention

[0023] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, FIGS. 3 to 6, in order to fully understand the present invention. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. It should be noted that in each drawing, identical components may be illustrated with the same reference numerals. Detailed descriptions of known functions and components that are deemed to unnecessarily obscure the essence of the present invention are omitted.

[0024] A lock handle structure with a voltage tester mounted according to an embodiment of the present invention comprises: a tool body (50) made of an insulating material having a first internal space (51) formed on one side for mounting a voltage tester (40) and a bolt insertion part (53) formed on the other side for inserting a door bolt of an underground facility; and a handle (60) having a second internal space (61) formed on one side that is coupled with the first internal space (51) and a handle (63) installed on the other side for rotating the tool body (50).

[0025] That is, the tool body (50) is made of PE (Poly-Ethylene) and serves to provide ultra-lightweight insulation performance.

[0026] The inner surface of the second internal space (61) is fitted around the outer surface of one end of the tool body (50), and then the tool body (50) and the handle (60) are joined by a connecting pin (57). The connecting pin (57) connects the first connecting pin hole (52) formed on one end of the tool body (50) and the second connecting pin hole (62) formed on one end of the handle (60), thereby preventing the tool body (50) from rotating freely from the handle (60) when the handle (60) is rotated.

[0027] A steel plate (58) is attached to the inner surface of the bolt insertion part (53), and the steel plate (58) reinforces the strength of the tool body (50) made of PE (Poly-Ethylene), an insulating material, thereby preventing wear of the bolt insertion part (53) when the door bolt of the underground facility is fastened or loosened by the bolt insertion part (53).

[0028] A terminal insertion hole (54) is formed between the first internal space (51) and the bolt insertion part (53) so that the voltage terminal (42) of the voltage tester (40) passes through and contacts the iron plate (58), and the terminal insertion hole (54) serves to form a passage so that the voltage terminal (42) contacts the door bolt of the underground facility through the iron plate (58).

[0029] On one side of the circumference of the tool body (50), a power button exposure hole (55) and a lamp exposure hole (56) are respectively formed so that a power button (44) for turning on / off and a lamp (46) for checking operation status of the voltage tester (40) mounted in the first internal space (51) are exposed to the outside of the tool body (50).

[0030] In the second internal space (61), a coil-shaped spring (64) is installed to apply elasticity so that when the tool body (50) and the handle (60) are combined, the voltage detector (40) mounted in the first internal space (51) is pressed as closely as possible against the iron plate (58) or the door bolt of the underground facility.

[0031] The handle (63) is preferably made of a round rod of a certain length, and is made of a metal material with a through hole formed on one side of the handle (60) through which the handle (63) can move, or is made of a material having a frictional force greater than a certain amount so as not to slip when the handle (63) is held.

[0032] That is, since the handle (63) can be moved to protrude further to the left or right of the handle (60), the radius of rotation can be increased when a large force is required.

[0033] Meanwhile, the assembly method of a lock handle structure equipped with an electroscope according to an embodiment of the present invention includes the step of inserting an electroscope (40) through the opening of a first internal space (51) of a tool body (50); and the step of combining the tool body (50) and the handle (60) to close the opening of the first internal space (51).

[0034] At this time, the inspection terminal (42) of the above-mentioned voltage detector (40) protrudes into the bolt insertion part (53) of the above-mentioned tool body (50) by means of elastic force when the above-mentioned tool body (50) and the above-mentioned handle (60) are combined.

[0035] A steel plate (58) is attached to the bolt insertion part (53) by an insert method during the injection molding of the tool body (50).

[0036] As such, the present invention is a lock handle equipped with a voltage tester, comprising a tool body (50) made of insulating material that can accommodate a voltage tester (40) inside, with a bolt insertion part (53) formed therein for fastening or loosening the door bolt of an underground facility, and a handle (60) that includes a movable handle (63) that acts as a lid for the tool body (50) and can adjust the radius of rotation significantly when a large force is required. Therefore, when a worker uses the lock handle, the risk of musculoskeletal disorders or injuries can be minimized, and if charging or leakage occurs due to contact with a wire (connection point), etc., on the outer casing of an above-ground device, this can be immediately checked through the voltage tester (40), thus having the advantage of preventing electric shock accidents.

[0037] Meanwhile, the present invention is not limited to the embodiments described above, but can be implemented with modifications and variations within the scope of the essence of the invention, and such technical concepts to which modifications and variations are applied should also be considered to fall within the scope of the following patent claims.
