Abstract

The invention discloses a telescopic socket which mainly comprises an outer shell, an inner shell, a cover of the outer shell and a socket, the outer shell is sheathed on the outer surface of the inner shell, the cover of the outer shell is covered at an opening of the outer shell, a winding wheel and a screw rod are arranged in the inner shell, a gear I is arranged at one end of the winding wheel, a gear II is arranged at the corresponding end of the screw rod, the two gears are mutually meshed, a ratchet wheel is arranged at the other end of the winding wheel, a buckle is matched on the ratchet wheel, the buckle is fixed on the inner shell through a spring, the back end of the socket is connected with a telescopic line, the telescopic line is wound on the winding wheel, a switch is arranged on the cover of the outer shell by plug-in connection, and the tail end of the switch corresponds to the buckle. The telescopic socket has the beneficial effects that the telescopic socket combines the advantages of an ordinary socket and a wiring board, the socket can be arbitrarily stretched through the winding wheel and the telescopic line till the required position after embedding the whole socket in a wall, the trouble caused by using the wiring board is eliminated, and the socket can be taken back after the use, thereby not occupying the space or affecting the appearance.

Description

A kind of telescopic socket

Technical field

The present invention relates generally to the socket field of daily life, mainly is a kind of telescopic socket.

Background technology

Present normally used socket mainly is to be embedded within the walls, fixed-site is constant, if satisfy the requirement of different spaces, can only several sockets be installed more in different positions and realize, position the most easily when but not necessarily use at last the position of An Zhuaning sometimes, be not easily when therefore causing using, or the socket utilization rate of some position is not high, addresses this is that, generally be to use terminal block, move line to need position, but be to use also very inconveniently, and influence attractive in appearance.

Summary of the invention

The present invention will solve the shortcoming of above-mentioned prior art, and a kind of telescopic socket is provided.

The present invention solves the technical scheme that its technical problem adopts: this telescopic socket, mainly comprise shell, inner casing, casing cover and socket, shell is enclosed within the outside of inner casing, casing cover is placed on the opening part of shell, be provided with reel and screw rod in the inner casing, one end of reel is provided with gear I, a corresponding end of screw rod is provided with gear II, and two place's gears are meshing with each other, and the other end of reel is provided with ratchet, be combined with fastener on the ratchet, fastener is fixed on the inner casing by spring, and the rear end of socket is connected with line stretcher, and line stretcher is on reel, be plugged with switch on the casing cover, the end of switch is corresponding with fastener.

Interior cap is stamped in the side of described inner casing, and shell is enclosed within the outside of inner casing and interior cap.

The inside of described reel is provided with clockwork spring.

Be threaded on the described screw rod leaded, the line stretcher of socket passes the lead-in wire part on reel.

The inwall of described inner casing is provided with binding post, and the end of line stretcher is connected on the binding post.

The effect that the present invention is useful is: the present invention combines the advantage of common socket and terminal block, after embedding whole socket within the walls, can must stretch socket is random by reel and line stretcher, position up to needs, both saved and used the loaded down with trivial details of terminal block, and had to have overcome the irremovable defective of common socket fixed-site, socket can have been regained after using, can not take up room fully, influence attractive in appearance.

Description of reference numerals: shell 1, inner casing 2, interior cap 3, casing cover 4, switch 5, socket 6, reel 7, line stretcher 8, screw rod 9, binding post 10, lead-in wire part 11, clockwork spring 12, fastener 13, spring 14, gear I 15, gear II16, ratchet 17.

Embodiment

The invention will be further described below in conjunction with drawings and Examples:

As shown in the figure, this telescopic socket, mainly comprise shell 1, inner casing 2, interior cap 3, casing cover 4 and socket 6, interior cap 3 covers the side at inner casing 2, shell 1 is enclosed within the outside of inner casing 2 and interior cap 3, casing cover 4 is placed on the opening part of shell 1, be provided with reel 7 and screw rod 9 in the inner casing 2, the inside of reel 7 is provided with clockwork spring 12, one end of reel 7 is provided with gear I 15, a corresponding end of screw rod 9 is provided with gear II 16, two place's gears are meshing with each other, produce transmission of power, the other end of reel 7 is provided with ratchet 17, be combined with fastener 13 on the ratchet 17, fastener 13 is fixed on the inner casing 2 by spring 14, resetting of spring 14 control card fasteners 13, the rear end of socket 6 is connected with line stretcher 8, line stretcher 8 is on reel 7, be threaded on the screw rod 9 leaded 11, the line stretcher 8 of socket 6 passes lead-in wire part 11 on reel 7, the design of lead-in wire part 11 can make line stretcher 8 neat must being wrapped on the reel 7, the tensile elongation of line stretcher 8 cooperatively interacts by fastener 13 and ratchet 17 and fixes, be plugged with switch 5 on the casing cover 4, the end of switch 5 is corresponding with fastener 13, and may command fastener 13 breaks away from ratchet 17, the inwall of inner casing 2 is provided with binding post 10, and the end of line stretcher 8 is connected on the binding post 10.

During use, available hand is directly arrested socket 6 and is outwards stretched, the stretching of line stretcher 8 drives reel 7 rotations, by pitch wheel I 15 and gear II 16, reel 7 drives screw rod 9 rotations, makes lead-in wire part 11 parallel mobile on screw rod 9, constantly draw line stretcher 8, when moving the length that needs to, stop to stretch, fastener 13 is stuck on the ratchet 17 of reel 7 by spring 14 effects, reel 7 stops operating, when using end, press switch 5, switch 5 bottoms are pressed on the fastener 13, fastener 13 breaks away from ratchet 17, reel 7 is by the effect of clockwork spring 12, and opposite spin is wrapped in line stretcher 8 on the reel 7.Also can or press the tensile elongation that switch 5 is regulated line stretcher 8 by stretching socket 6.

In addition to the implementation, all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of requirement of the present invention.
