Embodiment
For making the object of the utility model embodiment, technological scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described.
In description of the present utility model, it should be noted that, first define term " front " " afterwards ", being " front " near the direction of power-line plug, being " afterwards " away from the direction of power-line plug; In addition, term " on ", the orientation of the instruction such as D score, "left", "right" or position relationship be for based on position relationship shown in the drawings being only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
Consult Fig. 3-Fig. 5, it is the structural representation of an embodiment of the power line cover plate that the utility model proposes, power line cover plate in the present embodiment is the power line 1 for fixed flat planar TV, power line 1 has and has three-back-shaped block 11 and lug 12, three-back-shaped block 11 is by the little block 111 be superimposed together and large block 112, lug 12 is provided with for fixing screw hole; Power line cover plate comprises cover board body 2, and cover board body 2 is provided with the bounding means 22 of engagement portion 21 and restriction lug 12 movement engaging three-back-shaped block 11.
By arranging engagement portion 21 and bounding means 22 on cover board body 2, three-back-shaped block 11 is fastened on engagement portion 21, namely engagement portion 21 limits the degrees of freedom of three-back-shaped block 11.In the present embodiment, chamber engagement portion 21 having and holds little block 111 is set, namely little block 111 is positioned at engagement portion 21, the ear end face of the front-end face laminating engagement portion 21 of large block 112, thus by arrange engagement portion 21 define power line 1 to left and right, upper and lower, the front degrees of freedom to movement.The ear end face of lug 12 contacts with the front-end face of bounding means 22, thus defines the degrees of freedom of the backward directions movement of power line 1 by arranging bounding means 22.When power line 1 is mounted with on power line cover plate, three-back-shaped block 11 is fastened on engagement portion 21 by first-selection; Afterwards, lug 12 is pressed downwards, the ear end face of lug 12 is contacted with the front-end face of bounding means 22; Finally, fixed by lug 12 by screw hole and cover board body 2, such power line 1 is just firmly fixed on cover board body 2, completes being mounted with of power line 1.
Power line cover plate in the present embodiment, by arranging engagement portion 21 and bounding means 22 on cover board body 2, the soundness fixing by power line 1, ensure that to draw outside power line and can meet safety certificate standard-required with during interior pushing away.The structure of power line cover plate is simple, makes the fixing assembling of power line also comparatively simple, improves efficiency of assembling, saved cost of labor; And eliminate power clip, make the component fixed few, saved component cost.
Should be understood that, the concrete structure of engagement portion 21 is not as limit, engagement portion 21 also can be have the chamber holding little block 111 and large block 112, or is provided with and holds large block 112 chamber, as long as can be adaptive and limit three-back-shaped block 11 and move and all can with three-back-shaped block 11.
Power line cover plate in this example can adopt integrated injection molding.
Be fixed in order to power line 1 is put into engagement portion 21, engagement portion 21 is provided with the opening for power line being put into engagement portion 21.Power line 1 is first put into opening, draws forward power line 1 afterwards, little block 111 is fastened in engagement portion 21.
In the present embodiment, engagement portion 21 comprises two the first baffle plates 211 be oppositely arranged and defines with each first baffle plate 211 second baffle 212, first connected vertically baffle plate 211 and second baffle 212 chamber holding little block 111; Wherein the first baffle plate 211 limits the degrees of freedom that little block 111 moves left and right, second baffle 212 and cover board body 2 limit the degrees of freedom that little block 111 moves up and down, again because the ear end face of the first baffle plate 211 all contacts with the front-end face of large block 112 with the ear end face of second baffle 212, thus the first baffle plate 211 and second baffle 212 limit the degrees of freedom that large block 112 moves forward.In order to the assembly manipulation of power line 1 is simple, be arranged on by the opening on engagement portion 21 on second baffle 212, in other embodiments, opening also can be opened on the first baffle plate 211.
Shown in Fig. 3-5, more firm in order to what make power line 1 fix, block reinforcement 214 before engagement portion 21 is provided with, front block reinforcement 214 arranges the front end of the first baffle plate 21, front block reinforcement 214 contacts with the front-end face of little block 111, limit the movement of power line 1 forward direction, movement when namely stoping power line 1 to be subject to outer power of drawing.
In order to the area of contact of the front-end face of the ear end face and large block 112 that increase engagement portion 21 further, namely increase lifting surface area between the two, increase soundness, block reinforcement 215 after the ear end face place of engagement portion 21 is arranged, namely the front-end face of large block 112 contacts with the ear end face of rear block reinforcement 215, increase the lifting surface area between large block 112 and engagement portion 21, increase the soundness that power line 1 is subject to outer power of drawing.Wherein, rear block reinforcement 215 is arranged on the rear end of the first baffle plate 21.
Offering recess 26 in cover board body 2 front end, as the outlet of power line 1 extracting power supply cord cover plate, is also the outlet of drawing flat-panel TV shell.
In order to ensure further power line install after firm, corbel back slab 23 before cover board body 2 also has, front corbel back slab 23 is arranged between engagement portion 21 and recess 26, is positioned at the left and right sides of power line.Like this by arranging front corbel back slab 23, in front portion, engagement portion 21, certain restriction being carried out to moving left and right of power line, being conducive to the soundness after ensureing power line 1 installation, and when power line 1 is installed, there is guiding function.
In order to improve the fixing efficiency of power line, cover board body 2 is also provided with cross-rib 24, screw hole on lug 12 is fixed on cross-rib 24, utilizing the natural resiliency of lug 12 to be out of shape is assembled on cross-rib 24, this avoid to adopt and be screwed, make to install simply, improve installation efficiency.Cross-rib 24 is arranged on before bounding means 22.
Bounding means 22 is provided with stiffening rib 221, which increases the intensity of bounding means 22; Preferably, stiffening rib 221 is arranged on bounding means 22 front-end face, and the ear end face of such lug 12 contacts with stiffening rib 221, contributes to the tightness that improve both contacts.
Cover board body 2 also arranges supporting plate 25, for holding power line 1, and be provided with the groove of arc on supporting plate 25, power line 1 is positioned at groove after installing, further ensure power line fix after soundness, when power line 1 being installed, there is guiding function simultaneously.
The above, it is only preferred embodiment of the present utility model, be not restriction the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But everyly do not depart from technical solutions of the utility model content, any simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
