Description
Technical Field
The utility model relates to an electrical apparatus especially relates to an electrical apparatus waterproof construction that is qualified for next round of competitions.
Background
The existing outlet waterproof structure of the electrical appliance refers to fig. 1. Including electrical apparatus shell 1, be provided with wire hole 11 in the shell 1, be provided with swivel nut 2 on the wire hole 11, be provided with rubber sleeve 3 in the swivel nut 2, power cord L wears out from rubber sleeve 3, and 2 overcoat of swivel nut are equipped with nut 4, and nut 4 inboard is provided with conical surface 41. In the process that the screw cap 4 is screwed into the screw sleeve 2 from the outer side of the electric appliance shell 1, the conical surface 41 extrudes the rubber sleeve 3 to be attached to the power line L, and when the torque of the screw cap 4 reaches a preset value, rainwater can be prevented from entering the shell 1. Because the material of rubber sleeve 2 is soft, and the frictional force with nut 4 is great, when nut 3 rotated the extrusion, rubber sleeve 2 played the fold easily, led to producing the space between it and the power cord L, waterproof unreliable.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a lighting lamp reflector mounting structure with high light-emitting efficiency and simple structure.
The utility model provides a technical means that its technical problem adopted is: the utility model provides an electrical apparatus waterproof construction that is qualified for next round of competitions, includes the electrical apparatus shell, is provided with the wire hole in the shell, is provided with the swivel nut on the wire hole, is provided with rubber sleeve in the swivel nut, and the power cord is worn out from rubber sleeve, and the swivel nut overcoat is equipped with the nut, and the nut inboard is provided with the conical surface, still be provided with the clamping ring of stereoplasm between rubber sleeve and the swivel nut, be provided with a plurality of spaced pressure claws each other on the clamping ring, press the claw around rubber sleeve periphery evenly distributed, the conical surface oppression of nut is in press on the claw, press the claw oppression to be in on the rubber sleeve.
The utility model has the advantages that: because still be provided with the stereoplasm clamping ring between rubber sleeve and swivel nut, be provided with a plurality of pressure claws spaced each other on the clamping ring, when the nut oppressed the pressure claw, the pressure claw utilizes clearance space to the shrink of rubber sleeve, oppresses on rubber sleeve, can not lead to rubber sleeve to play the fold, and rubber sleeve and power cord are attached inseparabler, and is waterproof more reliable.

Detailed Description
The present invention will be described in further detail with reference to the following drawings and examples.
Refer to fig. 2 to 5. The utility model provides an electrical apparatus waterproof construction that is qualified for next round of competitions, includes electrical apparatus shell 1, is provided with wire hole 11 in the shell, is provided with swivel nut 2 on the wire hole, is provided with rubber sleeve 3 in the swivel nut 2, and power cord L wears out from rubber sleeve 3, and the swivel nut overcoat is equipped with nut 4, and the nut 4 inboard is provided with circular conical surface 41. Still be equipped with clamping ring 5 between rubber sleeve 3 and the nut 4, clamping ring 5 is made by rigid plastic, and plastics that have self-lubricating property such as preferred rigid PVC and nylon. The pressing ring 5 is provided with a plurality of pressing claws 51, the pressing claws 51 are spaced from each other and have gaps 50, the pressing claws 51 are uniformly distributed around the periphery of the rubber sleeve 3, the conical surface 41 of the screw cap 4 is pressed on the pressing claws 51, and the pressing claws 51 are pressed on the rubber sleeve 3.
As a variation of the present invention, the threaded sleeve 2 may be integrated with the electrical housing 1, or may be a separate structure. When the split structure is adopted, the thread insert 2 penetrates into the wire outlet hole 11, then the thread inserts 2 on the inner side and the outer side of the wire outlet hole 11 are respectively screwed with the nuts M, and the two nuts M fix the thread insert 2 in the wire outlet hole 11; or the nut M on the inner side of the wire outlet hole 11 and the threaded sleeve 2 are manufactured into an integral structure, and the nut M is screwed on the outer side of the wire outlet hole 11 to fix the threaded sleeve 2 in the wire outlet hole 11.
As a further improvement of the present invention, the pressing claw 51 is disposed along the screwing direction of the nut 4 in an inclined manner. Therefore, in the screwing process of the nut 4, the pressing claw 51 is not easy to be driven to shift or turn, the water resistance is more reliable, and the screwing of the nut 4 is smoother. The outer side of the pressing claw 51 is provided with a chamfer 52 matched with the conical surface 41 of the screw cap 4, so that the screw cap 4 is attached to the pressing claw 51 more tightly and is more reliable in water resistance.
As the utility model discloses further improve, 3 peripheries of rubber sleeve are provided with spacing step 31, and 5 terminal surface butts of clamping ring are in on the spacing step 31, like this, the equipment and the location of clamping ring 5 and rubber sleeve 3 are more convenient.
Because be provided with the stereoplasm clamping ring between rubber sleeve and swivel nut, be provided with a plurality of pressure claws that have gapped on the clamping ring, when the nut oppressed the pressure claw, the pressure claw utilized the clearance space to the shrink of rubber sleeve, oppressed on rubber sleeve, can not lead to rubber sleeve to play the fold, and rubber sleeve and power cord are attached inseparabler, and is waterproof more reliable.
The above description of the specific embodiments is only the preferred embodiments of the present invention, and does not represent the limitation of the protection contents of the present invention, and any technical solutions that can be obtained by normal reasoning of the ordinary technicians in the spirit of the present invention are the protection scope of the present invention.
