According to technical scheme, the decorative ring of the electric fan can be formed in an extrusion mode, after the two ends of the mesh cover decorative ring of the electric fan are inserted into the decorative ring insertion groove of the connector, the press arms press the outer ring of the front mesh cover and the outer ring of the rear mesh cover at the same time, it is ensured that the front mesh cover and the rear mesh cover cannot rotate due to external disturbance, and the manufacturing cost of the decorative ring can be reduced through the extrusion forming mode; in addition, the connector is matched with the decorative ring in outline structure, the connector for the decorative ring has quite good concealment performance, and appearance consistency of the decorative ring can be quite good.
Description
Technical field:
The utility model relates to a kind of electric fan used for decorative ring connecting head.
Background technique:
In electric fan industry, front mesh enclosure and rear net cover need plastics ring that the two is closely coupled together when mounted, in order to be that ring two ends couple together, traditional structure is at the two ends of ring, to form respectively the connecting head of protrusion, attachment screw connects, ring two ends are coupled together, the ring of this structure, between front mesh enclosure and rear net cover meeting and ring, can mutually rotate because of External Force Acting, and the connecting head profile of protruding is very ugly, disguise is not high, affects the overall aesthetics of electric fan.
In order to overcome above-mentioned defect, there is producer to design a ring, its structure is integrated, need of production adopts molding and forming, the manufacturing efficiency of molding and forming is very low, cause ring cost of production high, on this kind of ring, be designed with in addition the fitting seat of protrusion, on fitting seat, be provided with pressure arm, this pressure arm can rotate, but pressure arm can only be pushed down the outer ring on rear net cover, can not push down the outer ring of front mesh enclosure, cause existing the possibility of mutually rotating, front mesh enclosure rotation can cause the middle ring on front mesh enclosure just not installing between front mesh enclosure and ring.
Summary of the invention:
It is low that the purpose of this utility model is to provide a kind of cost, can avoid rotating between front mesh enclosure and rear net cover and ring, improves the used for decorative ring connecting head of electric fan monnolithic case aesthetics.
The technological scheme that the utility model provides is: a kind of electric fan used for decorative ring connecting head, include front and rear, front portion forms the ring slot injecting for ring two ends, and rear portion is provided with pressure arm, and the front end of pressure arm stretches out forward and can push down simultaneously the outer ring of electric fan front and back guard.
At rear portion, be provided with jack hole, the both sides of jack hole are provided with axis hole, and both sides, pressure arm middle part are provided with rotating shaft, and pressure arm front end passes jack hole, and extends ring slot place, and axis hole is compressed in rotating shaft, and the rear end of pressure arm is provided with locking device.
Described locking device consists of groove and the first anticreep protuberance, and groove is molded on the bottom at rear portion, and the first anticreep protuberance is molded over groove both sides.
Described locking device consists of through hole and screw, at rear portion and corresponding position, pressure arm rear end, all forms through hole, and screw screws through two through hole.
Opening at axis hole is provided with the second anticreep protuberance.
At ring slot inner bottom part, be protruding with two dops.
Adopt after the technical program, electric fan ring can adopt extruding and moulding, after pegging graft in the two ends of electric fan guard decoration ring in the ring slot of connecting head, be subject to pressure arm and push down the outer ring of front mesh enclosure and rear net cover simultaneously, guarantee that front mesh enclosure and rear net cover all can not be subject to external interference and rotate, extruding and moulding can reduce the manufacture cost of ring, in addition, form structure and the ring of connecting head are suitable, and its disguise is very strong, make ring profile conformity very good.
Accompanying drawing explanation:
Figure l is one of three-dimensional exploded view of the utility model electric fan used for decorative ring connecting head;
Fig. 2 be the utility model electric fan used for decorative ring connecting head three-dimensional exploded view two;
Fig. 3 is one of three-dimensional structure diagram of the utility model electric fan used for decorative ring connecting head;
Fig. 4 be the utility model electric fan used for decorative ring connecting head three-dimensional structure diagram two.
Embodiment:
Now elaborate by reference to the accompanying drawings the technical program:
The electric fan used for decorative ring connecting head of the present embodiment includes front portion 1 and rear portion 2, anterior 1 forms the ring slot 3 injecting for ring two ends, rear portion is provided with pressure arm 4, the front end 5 of pressure arm 4 stretches out forward and can push down simultaneously the outer ring of electric fan front and back guard, before and after anterior 1 profile curvature and electric fan, guard is suitable, thereby make connecting head very consistent with ring profile, improve the overall appearance degree of electric fan.
At rear portion, 2 are provided with jack hole 6, and the two bottom sides of jack hole 6 is provided with axis hole 7, at the opening of axis hole 7, are provided with the second anticreep protuberance 8.Pressure arm 4 both sides, middle part are provided with rotating shaft 9, pressure arm front end 5 is through jack hole 6, and extend ring slot 3 places, pressure arm front end 5 is provided with two paws 15, between two paws 15, be provided with the gap 10 that can pierce into for guard iron wire, thereby block front mesh enclosure and rear net cover simultaneously, avoid rotating between front mesh enclosure and rear net cover and ring, during installation, axis hole 7 is compressed in rotating shaft 9, now to overcome the obstruction of the second anticreep protuberance 8, after compressing into, rotating shaft 9 just can not take off again, before compressing into, pressure arm front end 5 is first through jack hole 6, after compressing into, pressure arm 4 can rotate around jack hole 6, the rear end 11 of pressure arm 4 is provided with locking device.
