Abstract
The invention discloses a power wire electric-drop protector in the field of wire coiling device compound. It comprises a power wire and a wind spring, wherein the two ends of the wind spring are connected with the guide block end and the guide block head with the center hole; the power wire is coiled in the spring and separately integer inside the center hold of the guide block end and the guide block head; the guide block head is formed by a circular guide block head plate on one side, a concentric circular guide block plug on the other side and a card groove between them; the guide block end is formed by a circular guide block end plate and a concentric wire pipe.
Description
Technical field
The present invention relates to the combination of electric wire wind, specifically is that a kind of avoiding causes power-line plug to be extracted from socket owing to the artificial origin in the dust suction work, reduces the power cord non-electricity protector of power line fracture in the product simultaneously.
Background technology
Dust suction is a kind of sanitation and hygiene electrical equipment, is used for removing the dust in ground, carpet, wall, furniture, clothing and various slits.
In general, dust catcher comprises the motor of dust collector that is generated suction by the power supply that imports substantially, forms suction nozzle, flexible pipe, the filter bag of air path system, gathers the dust collecting part of inhalation (inhalatio).In prior art, the power line of vertical type dust collector is directly outer being hung on the fuselage mostly, and it is different from the horizontal dust collector part is the length caution sign that does not have power line.So, when using vertical type dust collector, if working range surpasses power line length, be easy to cause power line from supply socket, to extract, make operator's energized of having to return again, make troubles to the user, simultaneously, frequent pulling causes power line fracture in the product easily, and omission in the product quality inspection.
Summary of the invention
The present invention is in order to solve the power line length that causes easily in the common vertical type dust collector use and to surpass working range; cause power line from electricity and socket, to extract easily; and pull power line breakage problem in the product that causes, and a kind of power cord non-electricity protector is provided.
The present invention realizes by following technical scheme.
A kind of power cord non-electricity protector comprises power line and coil spring; Its coil spring two ends are connected with the guide block tail and the guide block head of centre bore respectively, and the power line that runs through therebetween unrolls in spring, and constitute one respectively with in the centre bore of guide block tail and guide block head; The guide block head is by the circular guide block head-clamp plate of a side, and the circular concentric guide block plug of opposite side reaches the draw-in groove that forms one therebetween and constitutes, and the guide block tail is integrally formed by circular guide block tail clamping plate and concentric conductor pipe.
The advantage that has of She Ji the present invention is like this: when the working range of dust catcher exceeded power line length, spring was given response of operator, was that the operator in time obtains the feedback prompting, avoided plug to be pulled out.The power line that also makes simultaneously electrical appliance such as dust catcher one end has been cut down a checkout procedure consuming time not rupturing behind the folding pendulum repeatedly for a long time.

Embodiment
Describe the present invention below in conjunction with drawings and Examples.
Spring among Fig. 1,2 is the state when drawing back.
A kind of power cord non-electricity protector, comprise power line 13 and coil spring 12, its coil spring 12 two ends are connected with guide block tail 7 and the guide block head 3 of centre bore 10.11. respectively, the power line 13 that runs through therebetween unrolls in spring 12, and constitutes one respectively with in the centre bore 10.11. of guide block tail 7 and guide block head 3; The guide block head is made of the circular concentric guide block plug 6 of the circular guide block head-clamp plate 4 of a side, opposite side and the draw-in groove 5 that forms one therebetween, and guide block tail 7 is integrally formed by circular guide block tail clamping plate and concentric conductor pipe 9.
Described power cord non-electricity protector is coated with insulating varnish on its coil spring 12.
Described power cord non-electricity protector, its guide block tail 7 and guide block head 3 are by the injection mo(u)lding respectively of PVC material.
Described power cord non-electricity protector. its guide block head-clamp plate 4 diameters〉guide block plug 6〉draw-in groove 5.
Described power cord non-electricity protector, the power line 13 of its affixed respectively guide block tail 7 and guide block head 3 is quadric injection mould one and draws.
Usually, spring 12 is deflated states, the power line 13 that unrolls in it, and the guide block plug 6 of guide block head 3 other ends inserts in the vacuum cleaner bottom 1, and on the power line aperture that draw-in groove 5 is embedded in.Power line 13 length of unrolling in the spring 12 are not less than the length that spring draws back.Pull under the situation of power line 13 during use, the response of spring 12 can be given prompting of user, avoids plug to be pulled out.
Claims (5)
1. power cord non-electricity protector, comprise power line and coil spring, it is characterized in that the coil spring two ends are connected with the guide block tail and the guide block head of centre bore respectively, the power line that runs through therebetween unrolls in spring, and constitutes one respectively with in the centre bore of guide block tail and guide block head; The guide block head is made of the circular concentric guide block plug of the circular guide block head-clamp plate of a side, opposite side and the draw-in groove that forms one therebetween, and the guide block tail is integrally formed by circular guide block tail clamping plate and concentric conductor pipe.
