Description

The supply socket of band automatic wire winding function

Technical field

The utility model relates to a kind of supply socket, relates in particular to a kind of supply socket with automatic wire winding function.

Background technology

In the middle of present daily life, various supply sockets are widely used, in many cases, there is bigger distance between electrical equipment that people use and the power supply, common Multi-purpose power socket can not be suitable for because of the power line limited length, and therefore, a kind of supply socket with automatic wire winding function is arisen at the historic moment, its power line is long and can be wrapped on the wire spool practicality more.As the patent No. is that ZL200310107912.0 (notification number is CN1276557C) Chinese invention patent " a kind of supply socket with wire spool " discloses so a kind of supply socket, it mainly includes the middle part and is provided with the support of rotating shaft and the wire spool that outer side panel is provided with socket, this wire spool is arranged in the rotating shaft rotationally and has auto take-up, the power line that is connected with socket just is wrapped on this wire spool, and an end of power line is connected with plug, and this auto take-up also is provided with by ratchet and cam and cooperates the drum rotary locking mechanism of forming.During use, plug is together pulled out together with the power line that is wound on the wire spool, plug is inserted on the fixing power supply, and the spring installing rack in the auto take-up cooperates card to establish by cam with ratchet to stop operating, realization power line length is located.But, this auto take-up comprises disc spring, spring installing rack and lid, the drum rotary locking mechanism is set on the spring installing rack, and the drum rotary locking mechanism is a fixed ratchet wheel on the spring installing rack, camshaft is set on lid, on this camshaft cam is set, cam cooperates with camshaft is movable, cam again with ratchet on ratchet be clasped, also need to be provided with elastic component between cam and the lid, so structure is too complicated, is unfavorable for processing, assembling, production cost is also higher, and participation is too much to the parts of auto take-up locking, causes the locking error easily, therefore, need further improvement.

Summary of the invention

Technical problem to be solved in the utility model is that the supply socket that a kind of lock out action is reliable, operation is more nimble, structure is simple more, be easier to the band automatic wire winding function of process and assemble is provided at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the supply socket of this band automatic wire winding function, comprise shell, be positioned at shell and be installed in wire spool in the rotating shaft rotationally, be wrapped in the auto take-up of power line on the wire spool and wire spool and wire spool is carried out spacing locking mechanism, wherein also be furnished with the socket that is electrically connected with power line on the lateral surface of wire spool, it is characterized in that: described locking mechanism comprises the runner with described wire spool coaxial rotation, one around the middle part pivotally supported fastener and top expose to the button of shell, the design of described runner outer has ratchet, the front end of described fastener has the trip that matches with above-mentioned ratchet, conflicting on the rear end of this fastener in the bottom of above-mentioned button, also is provided with simultaneously described trip to be had all the time with ratchet collude the spring that closes mutually between the front end of described shell and fastener.

For making wire spool have manual function of receiving line, the position that the lateral surface of described wire spool is exposed to described shell can be provided with a projection, and so, the user can control projection and rotate wire spool, realizes the purpose of manual operation wire spool.

As further improvement, the upper surface of described fastener front end can have the card post, and also has the card post on the described shell madial wall on the position of corresponding spring end accordingly, the two ends of described spring just are set in outside these two card posts respectively, so, just can be both ends of the spring is spacing by two card posts.

Described auto take-up can adopt existing various technology, simply, can comprise the cover plate that relatively is wrapped in the clockwork spring in the rotating shaft with described socket and covers the clockwork spring outside, the inner end of described clockwork spring and rotating shaft link to each other, outer end and described cover plate are connected mutually, so design also makes things convenient for auto take-up in the installation setting of that end of socket relatively.

Compared with prior art, advantage of the present utility model is: pass through runner, fastener, the locking mechanism design of elasticity accumulation of energy part and button, make the locking mechanism structure simpler, be easier to process and assemble, under nature, elasticity accumulation of energy part with the front end of fastener to lower swing and the ratchet buckle on runner, prevent that wire spool from arbitrarily rotating, need unlock and when wire spool is freely rotated, as long as button is pressed, button driver card fastener front end upwarps, trip on the fastener breaks away from the ratchet on the runner immediately, realizes the releasing of locking, this interaction relation design of locking mechanism, lock out action is very reliable, operates very nimble.
