Description

A kind of supply socket with wire spool

Technical field

The present invention relates to a kind of supply socket, especially relate to a kind of supply socket with wire spool.

Background technology

The supply socket of existing band wire spool has been widely used in the every field in the daily life, in many cases, people make between the place of electrical appliance and the power supply often has certain distance, and this moment, people selected one of method of solving to be to use the supply socket of band wire spool.The supply socket of existing band wire spool mainly comprises support and drum, the middle part of support is provided with rotating shaft, drum is movably arranged in the rotating shaft, the lateral surface of drum is provided with socket, be wound with on the drum and the socket wire connecting, an end of electric wire is connected with plug, during work, plug is inserted supply socket, and unwrapping wire will move to the electrical equipment place to use with the supply socket of wire spool then.This electric outlet structure is simple, is easy to carry, and it is longer to connect distance.The supply socket of a kind of band drum is disclosed as No. 01279906.8 Chinese utility model patent that on January 15th, 2003, bulletin was authorized, by structurally the socket dish being separated with drum, the conduction ring plate is set on the socket dish, the conduction contactor is set on drum, friction is mated and is connected between conduction contactor and the conducting ring place sheet, realizes being electrically connected between drum and the socket dish with this.This structure can be rotated drum with respect to the socket dish, and the socket dish keeps motionless effect when having realized the drum rotation.But the shortcoming that this product exists the supply socket of normal tape drum all to exist, be that take-up is adopted and to be shaken handle and drive drum and rotate and finish, very inconvenient, exist a shortcoming to be in addition because connector assembly and drum are will be in relative rotation, each other electrical connection relies between conduction contactor and the conducting ring place sheet friction to mate to be connected and finishes, so service time one is long, will certainly cause loose contact between conduction contactor and the conducting ring place sheet, cause easily and open circuit and socket can't be worked, so need do further improvement.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of simple and reasonable and have automatic wire winding function and the supply socket of the band wire spool that conducts electricity very well, be not easy to open circuit at above-mentioned prior art present situation.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of supply socket with wire spool, comprise support and drum, the middle part of support is provided with rotating shaft, drum is movably arranged in the rotating shaft, the outer side panel of drum is provided with socket, be wound with on the drum and the socket wire connecting, be provided with auto take-up in the described drum; Describedly comprise a disc spring, a spring installing rack and a lid from take-up, described spring installing rack is fixed on the inner panel of described drum, the described lid that is connected and fixed with support is provided with pin, described disc spring one end is fixed on the described spring installing rack, the other end of described disc spring is fixed on the described pin, and described spring installing rack is provided with the drum rotary locking mechanism; Described drum rotary locking mechanism is to fixedly install a ratchet on described spring installing rack, one camshaft is set on described lid, described camshaft is provided with cam, described cam cooperates with described camshaft is movable, the ratchet of described cam and described ratchet is clasped, and the circumference of described ratchet is provided with no toothed portion.

Described no toothed portion can be smooth arc surface, also can be plane or concave surface, its objective is make between cam and the ratchet snap into that this part produce to be threaded off and no longer locked, thereby drum is reversed under the effect of disc spring, the power line of pulling out is regained.

For make between cam and the ratchet be clasped can be more effective, can be provided with flexible member between described cam and the described lid, its effect is to make described cam can be adjacent to described ratchet all the time.

Described flexible member can be an extension spring, also can be elastic spring.

Compared with prior art, the invention has the advantages that the medial surface at drum is provided with an auto take-up, can be with this device easily with the electric wire automatic drawing back of pulling out, and need not use handle to shake drum, greatly facilitate user's use; The drum rotary locking mechanism of being made up of cam and ratchet guarantees that electric wire can be fixed in effective arbitrarily service range easily, and can regain at any time as required; Flexible member is set on cam can applies an elastic compression power to cam, make cam be adjacent to ratchet all the time, being clasped between assurance cam and the ratchet can be more effective; Because socket and drum directly install and fix, do not need to rotate relatively, so the electric wire on the drum directly is connected with socket, do not need conductive contact film, so conduct electricity very well, can not open circuit; In a word, the invention provides a kind of simple in structurely, production and assembly are easy, and are convenient and practical, and good conductivity is difficult for opening circuit, reliable operation and have supply socket from the band wire spool of function of receiving line.
