Abstract

The invention relates to a wall switch with a retractable torsional strip, which comprises a torsional spring, a unidirectional disc, helical teeth and the like. The wall switch is characterized in that a wire coil is sleeved on the torsional spring, the torsional spring buckles the unidirectional disc, the wire coil, the torsional spring and the unidirectional disc are overlapped together, a hook of the torsional spring is hooked on a positioning hole of the main body, a pressing bar passes through the main body and pushes against a pressure spring, the other end of the pressure spring pushes against a side shell of the main body, the pressing bar is pushed outwards under the action of the resetting force of the pressure spring, an anti-rotating head which is 45 DEG outwards is arranged at the tail end of the pressing bar, the anti-rotating head is identical with the 45-DEG helical teeth of the unidirectional disc, and a lead wire of the wire coil is fastened on a lock hole of the socket. The socket has the same functions as those of the original socket, and the socket can also be stretched to overcome the defect that a power wire is not long enough.

Description

The telescopic switch on wall of a kind of torsion band

Technical field

The present invention relates to a kind of accessory of house ornamentation electrical equipment, is the telescopic switch on wall of a kind of torsion band concretely.

Background technology

Present wall socket all is fixed, runs into that the short partially or service range of electrical equipment line is remote also will to increase a flexible cord socket, brings a lot of inconvenience to operation.

Summary of the invention

The object of the present invention is to provide the telescopic switch on wall of a kind of torsion band, make on the basis that guarantees former function of socket, also have the socket stretching to satisfy the function that power line falls short of.

The present invention realizes with following technical scheme: the telescopic switch on wall of this a kind of torsion band is made up of main body, socket, depression bar, skewed slot, anti-rotary head, compression spring, rewiring plate, torque spring, unidirectional dish, helical teeth and limiting plate.It is characterized in that: rewiring plate is enclosed within on the torque spring, and torque spring fastens unidirectional dish, the overlapping one of three; The drag hook of torque spring is hooked on the location hole of main body, and depression bar passes the main body spring that withstands pressure, and the compression spring other end props up the limit shell of main body; In the past extrapolation of the effect down-pressed pole of compression spring reset force, the end of depression bar has one outside 45 ° anti-rotary head, and 45 ° of helical teeth of anti-rotary head and unidirectional dish match; Side at main socket body is respectively stretched out a limiting plate up and down; Limiting plate is used for guaranteeing socket the parallel of back and body surfaces that reset, and a skewed slot is respectively arranged, the length 20mm of skewed slot, width 15mm, degree of depth 5mm about socket; Skewed slot uses when being used for making things convenient for thumb and forefinger to pull out socket, and the lead of rewiring plate is fastened on the lockhole of socket.Go out socket with hand-lifting, lead drives rewiring plate and unidirectional dish rotates together, and helical teeth promotes anti-rotary head moves back depression bar outward, and helical teeth becomes the gap with the anti-rotation capitiform; Lead in the rewiring plate is together pulled out by smooth and socket, and torque spring also is being tightened up synchronously, when reaching Len req; Hand stops the pulling force to socket, unidirectional dish counter-rotating under the active force of torque spring, and the anti-rotary head of helical teeth on the unidirectional dish and depression bar offsets extremely; Rewiring plate is static, and socket breaks away from main body and forms Strip line socket, after electrical equipment is used to complete; Press the depression bar button of main body below, depression bar drives anti-rotary head and moves inward, after anti-rotary head and helical teeth stagger; Torque spring drives unidirectional dish and rewiring plate together reverses, and socket is got back to body position, has realized that socket breaks away from and the main functions that resets.

Beneficial effect is: the present invention has the socket stretching to satisfy the function that power line falls short of.

Embodiment

With reference to Fig. 1, Fig. 2, the telescopic switch on wall of a kind of torsion band of the present invention, its structure is made up of main body 1, socket 2, depression bar 3, skewed slot 4, anti-rotary head 5, compression spring 6, rewiring plate 7, torque spring 8, unidirectional dish 9, helical teeth 10 and limiting plate 11.In Figure of description, rewiring plate 7 is enclosed within on the torque spring 8, and torque spring 8 fastens unidirectional dish 9; The overlapping one of three, the drag hook of torque spring 8 are hooked on the location hole of main body 1, and depression bar 3 passes main body 1 spring 6 that withstands pressure; Compression spring 6 other ends prop up the limit shell of main body 1; In the effect down-pressed pole 3 past extrapolations of compression spring 6 reset forces, the end of depression bar 3 has one outside 45 ° anti-rotary head 5, and anti-rotary head 5 matches with 45 ° of helical teeth 10 of unidirectional dish 9.Side at main body 1 socket 2 is respectively stretched out a limiting plate 11 up and down; Limiting plate 11 is used for guaranteeing socket 2 surperficial parallel of back and main body 1 that reset; Socket about 2 respectively has a skewed slot 4; When being used for making things convenient for thumb and forefinger to pull out socket 2, the length 20mm of skewed slot 4, width 15mm, degree of depth 5mm, skewed slot 4 use.

Described rewiring plate 7 be disc type around the formula power line, the stretching length of power line is 3m.

Described torque spring 8 is the takeup type spring.
