Detailed Description
The present invention will be further described with reference to the following embodiments. Wherein the showings are for the purpose of illustration only and are shown by way of illustration only and not in actual form, and are not to be construed as limiting the present patent; to better illustrate the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.
The same or similar reference numerals in the drawings of the embodiments of the present invention correspond to the same or similar components; in the description of the present invention, it should be understood that if there is an orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", etc. based on the orientation or positional relationship shown in the drawings, it is only for convenience of describing the present invention and simplifying the description, but it is not intended to indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and are not to be construed as limiting the present patent, and the specific meaning of the terms may be understood by those skilled in the art according to specific circumstances.
Example 1
The power cord protecting sleeve of the embodiment is shown in fig. 1 and 2, and comprises a sleeve main body 1, wherein the sleeve main body 1 is provided with a threading hole 11 penetrating through the front end and the rear end of the sleeve main body 1, the threading hole 11 is a cylindrical hole, the outline of the cross section of the sleeve main body 1 is circular, and the center line of the threading hole 11 is collinear with the center line of the sleeve main body 1, so that the cross section of the sleeve main body 1 is circular.
In addition, the thickness of the side wall of the sleeve body 1 is increased from the middle portion to the front and rear ends, respectively, in this embodiment, the thickness of the side wall of the sleeve body 1 is increased from the middle portion to the front and rear ends, respectively, so that the outer side surface of the sleeve body 1 is a smooth surface.
When foretell power cord protecting wire cover used, as shown in fig. 3, power cord 2 wears to locate through wires hole 11, and through wires hole 11 aperture must be confirmed according to the power cord external diameter size, and through wires hole 11 should be as little as possible with power cord fit clearance, when guaranteeing the assembly effect, avoids power cord 2 to slide in through wires hole 11. Because cover main part 1 is little, the big waist drum shape in both ends in middle part, consequently the middle part of cover main part 1 is because the wall thickness is less and easy to be out of shape, when operation portable electric tool, power cord 2 can not be in the front and back tip bending of cover main part 11, and can be crooked in cover main part middle part, can increase power cord 2's bending radius like this, avoids the power cord to excessively drag the fracture damage that produces to this improves power cord life-span.
In addition, because the side wall of the sheath main body 1 is not provided with a groove position formed by the organ type wire sheath, and the outer side surface is a smooth surface, food residues are not easy to store on the surface of the wire sheath, and the sheath is easy to clean.
In order to facilitate the connection of the wire protection sleeve and the electric tool, the outer side wall of the rear end of the sleeve main body 1 is provided with a fixing groove 12, and the sleeve main body 1 is clamped with the electric tool through the fixing groove 12 to avoid the wire protection sleeve from sliding and falling off at will. The wall thickness of the sleeve main body 1 at the position of the fixing groove 12 is more than 2.5 times of the wall thickness of the position of the minimum wall thickness in the middle of the sleeve main body 1, and the power line is prevented from being excessively bent at the position of the wire protection sleeve fixing groove.
As the improvement scheme of this embodiment, the above-mentioned front end lateral surface and the preceding terminal surface of cover main part 1 are connected for the arc surface, avoid cover main part 1 to have the closed angle to injure the user, also convenient drawing of patterns during injection moulding.
The power line protecting sleeve can prolong the service life of the power line of the portable electric tool, is easy to clean and has simple structure. And the power cord protecting sleeve is preferably made of insulating flexible plastic with a flame-retardant effect, so that the safety is improved.
