Description

A kind of lamp holder rotational structure of desk lamp

Technical field

The utility model relates to a kind of desk lamp, especially a kind of rotational structure of desk lamp lamp holder.

Background technology

A kind of desk lamp is arranged at present on the market, it possesses a collapsible or flexible supporting bar structure, this support bar one end is installed lamp holder, the other end then is installed on the Desk lamp feet, can pass through to adjust the angle or the length of support bar during use, with the adjustment of realization lamp holder position, and when not using, then can amount to, be convenient to collection.Such desk lamp, because its support bar is folding or flexible rigid structure, be connected with Desk lamp feet by the mode that articulates, lamp holder also is connected with Desk lamp feet by the mode that articulates, therefore in use, support bar generally only can be realized with respect to the angle adjustment on dimension of Desk lamp feet, lamp holder also can only carry out an angle adjustment on the dimension on the support bar simultaneously, will make lamp holder adjust angle like this is restricted, can only in a dimension, rotate, when luminous work, if need more wide irradiating angle, then only can realize, use slightly inconvenience by moving whole desk lamp.

Summary of the invention

At the problems referred to above, the utility model provides a kind of structure that the relative support bar of lamp holder is rotated, so that the adjustment of lamp holder irradiating angle is more convenient.

The utility model is that the technical scheme that its technical problem of solution is adopted is:

A kind of lamp holder rotational structure of desk lamp comprises support bar and lamp holder, and outer, support bar end goes out a pivot position, this pivot position pivots pivotal part is installed, and the pivotal part middle part is provided with the hole, and described lamp holder tail end extends a bar portion, this bar portion limit mounting forms turntable in described hole.

The beneficial effects of the utility model are: the utility model forms the rotational structure of first dimension by pivot position and pivotal part, form the rotational structure of second dimension again by bar portion and pivotal part, therefore in use be, can make lamp holder two dimensions, be the four direction rotation, enlarged the slewing area of lamp holder, under the situation of not adjusting the desk lamp position, realized bigger lighting angle adjustment, used more convenient.

Description of drawings

Be further described below in conjunction with the drawings and specific embodiments:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a user mode schematic diagram of the present utility model.

The specific embodiment

With reference to Fig. 1, the lamp holder rotational structure of a kind of desk lamp provided by the utility model, comprise support bar 1 and lamp holder 2, outer, support bar 1 end goes out a pivot position 11, this pivot position 11 pivots pivotal part 3 is installed, and pivotal part 3 sidepieces are provided with hole 31, and described lamp holder 2 tail ends extend a bar portion 21, these bar portion 21 limit mounting form turntable in described hole 31.So, the position 11 that is equivalent to pivot has formed first dimension with pivotal part 3, and promptly lamp holder 2 is with respect to the rotation of support bar 1 in same plane, and bar portion 21 and pivotal part 3, then formed second dimension, promptly lamp holder is with respect to the rotation in Different Plane of support bar 1 or pivotal part 3; Both combinations have then realized the rotation of two dimensions, four angles.

Wherein, the position 11 that pivots is made up of the two symmetrical pivot block 110 that support bar 1 outer goes out, and described pivotal part 3 is between two pivot block 110; Pivotal part 3 then is designed to a sheet structure, and 32, the two bending positions 32, bending position that its both sides are provided with symmetry are connected with two pivot block, 110 pivots respectively; Described hole 31 is opened in the sheet middle part of pivotal part 3, make reasonable integral structure, stressed more balance, and the pivotal part 3 of sheet is convenient to get through hole 31, and hole 31 is cooperated with the installation of bar portion 21, and it can extend through hole 31 with rod member 21 afterbodys, two sides in the hole 31 of sheet, respectively at blocking last two snap rings in the bar portion 21, radially fixing with administration, and stay circumferential rotation dimension; In the practical structures, adjust pivot position 11 and pivotal part 3, the assembling elasticity in bar portion 21 and hole 31 makes structure slightly tight, can be so that lamp holder 2 can be fixed on the angle that needs and be not easy to become flexible; And can make hole 21 be set to polygon, and and a polygon ring-type of disturbing mutually with hole 31 is set in bar portion 21, when the user turns to the position that hole 31 and polygon ring-type match, then can obviously feel the stress that puts in place, be difficult for looseningly, and use good hand touch.

For the ease of the cabling of lamp holder 1 inside conductor, bar portion 21 can be designed to hollow tube-shape in addition, and an end passes to lamp holder 1 inside, and the lead that is connected with light source is therefrom introduced, and the other end is then drawn lead, so that lead connects external circuit.Therefore corresponding, pivot block 110 is provided with and is communicated to support bar 1 interior cable hole 111 for cabling, makes lead introduce support bars 1 from this cable hole 111, go on the external circuit from support bar 1 again, this structure makes lead stash, good looking appearance, and safe and reliable.

In the utility model, if lamp holder 2 is excessive with respect to the rotational angle of original position, may cause that lead is screwed in together, cause and open circuit, therefore can increase by a position limiting structure, preferred scheme is: bar portion 21 sides are provided with a projection 211, the hole 31 other blocks 311 of a retaining on the circumferential movement path of projection 211 that are provided with of described pivotal part 3.No matter bar portion 21 toward which direction rotates a circle like this, projection 211 all can be subjected to stopping of block 311, thereby can not rotate bigger angle, when guaranteeing that lamp holder 2 has enough rotational angles, has eliminated the hidden danger of bringing because of rotation.

As shown in Figure 2; the utility model in use, support bar 1 may be telescopic, after the expansion; adjust the angle of lamp holder 2 again; just can access and make customer satisfaction system lighting angle, easy to use, and in practical structures; can be coated with protecting sheathing 4 in the position 11 that pivots; the parts that pivot are all coated, good looking appearance, and reach the effect of guard block and lead.
