CN201594964U - Power wire hook - Google Patents

Abstract

The utility model discloses a power wire hook which avoids the potential safety hazard generated by a power wire being scratched after the whole machine power wire is wound on the hook. A hook body and a shell body of the power wire hook are formed into a whole structure; edges and corners on the hook body are all provided with arc-shaped transitional surfaces; a port surface of the hook body, at the position opposite to the shell, is provided with a boss; and the boss is in the shape of cylinder, and the hook body is in the shape of L. The power wire hook is applicable to various electrical apparatuses with the power wires, especially household appliances.

Description

Flex hook

Technical field

The utility model relates to a kind of hook, in particular for the hook of fixed power source line.

Background technology

Flex hook mainly to the power line of electrical equipment play fixing, prevent the effect that it is at random or scratched.Structure and the utility model of fixed power source line in patent 031305032 in the disclosed scheme are similar, i.e. direct designing power supply line hook on casing.At present, this structure also can be seen on daily household electrical appliance, but this kind scheme has only been considered the needs of plastic shaping to mold releasability owing to the designer, and does not consider the chosen position of plastics die joint when in-mold molding fully, thereby causes the every part that can contact with power line of hook, especially seamed edge,, all be comparatively sharp seamed edge or wedge angle, when fixing power line on it all without any circular arc, easily power line is scratched, cause potential safety hazard.

The utility model content

The technical problem that the utility model solved provides a kind ofly to be avoided the complete machine power line to be wrapped in hook going up the back and be scratched the flex hook that causes potential safety hazard because of power line.

The technical scheme in the invention for solving the technical problem is: the flex hook that the utility model relates to, comprise coupler body, and coupler body and housing are structure as a whole, and limit, angle on the coupler body are provided with arc transiting surface.

As a kind of improvement of the present utility model, the port surface of described coupler body is provided with boss to the casing place.

Further, described boss is cylindrical.

As a kind of optimal way of the present utility model, coupler body is L-shaped.

The beneficial effects of the utility model are: be arc transiting surface all with the power line contact portion on the flex hook, avoided the complete machine power line to be wrapped in hook and caused potential safety hazard because of power line is scratched when going up.Simultaneously prevented effectively that at the boss that is provided with on the coupler body power line is wound in that the back comes off because of the external force effect on the hook.Do not need to increase in addition wire clamp or other part, reduce part material and use and management cost, improved production efficiency again.

Be labeled as among the figure: 1-coupler body, 2-arc transiting surface, 3-housing, 4-boss.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

As shown in Figure 1 and Figure 2, coupler body 1 is structure as a whole with housing 3, limit on the flex hook, angle are arc transiting surface 2, promptly be beneficial to this hook of moulding and be convenient to again on the basis of mold releasability taking into full account, seamed edge is designed to circular arc around will linking up with, with the mould parting Surface Design of this hook of moulding in position that power line can not touch, then the part that contacts with power line of flex hook is without any overlap or wedge angle, guaranteed that power line is not scratched, scratches, guaranteed the order of power line placement and the fail safe of complete machine.

For prevent power line be wrapped on the flex hook after because of the external force effect comes off, to the casing place boss 4 is set at the port surface of coupler body 1.Boss 4 is with coupler body 1 moulding.To shown in Figure 4, boss 4 can be wedge shape, also can cylindrical or hemisphere as Fig. 2.Wedge shape and hemispheric boss all have certain angle or radian up and down, the picking and placeing of more convenient power line, but the moulding difficulty is bigger, simple for mould structure, be convenient in demoulding reach simultaneously prevent power cord from purpose, boss 4 preferred versions are cylindrical.Because the restriction of boss 4, power line just are not easy from flex hook disengaging, at random outside housing 3.

Coupler body 1 is whole L-shaped, also can adopt semicircle to wait other shape, because L shaped coupler body 1 is easy to manufacturing, and overall appearance, coupler body 1 of the present utility model adopts L shaped as preferred version.

Claims (4)

1. flex hook comprises coupler body (1), and coupler body (1) is structure as a whole with housing (3), and it is characterized in that: limit, the angle on the coupler body (1) is provided with arc transiting surface (2).

2. flex hook as claimed in claim 1 is characterized in that: the port surface of described coupler body (1) is provided with boss (4) to the casing place.

3. flex hook as claimed in claim 2 is characterized in that: described boss (4) is cylindrical, wedge shape or hemisphere.

4. flex hook as claimed in claim 1 or 2 is characterized in that: described coupler body (1) is L-shaped.
