A kind of tumbler of desk lamp
Technical field
The present invention relates to the tumbler of a kind of desk lamp.
Background technology
Common portable desk lamp is generally individually designed as compact structure to meet its use demand, and, in order to improve platform
The illuminating effect of lamp, it is both provided with bascule greatly so that its lamp body activity regulates flexibly, thus changes illumination
Scope and effect, have the most on the market some have can folding or rotate the desk lamp of lamp body, it can be arranged made by movable device
Desk lamp folding or rotation, but, this structure does not have damping, and therefore activity adjustment may not be without under external force situation
Stable, particularly desk lamp lamp body own wt is natural is formed with certain moment, the most undamped bascule with regard to team's structure
Or rotational structure be inconvenient to use.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention provides the tumbler of a kind of desk lamp, and it can realize the band of desk lamp
Damping rotary.
The technical solution adopted for the present invention to solve the technical problems is:
The tumbler of a kind of desk lamp, including the hinged seat on the lamp socket for being arranged on desk lamp, and is arranged on the lamp body of desk lamp
On union joint, described hinged seat is provided with the hinge hole for hinged described union joint, is provided with and is connected in this hinge hole
The damping connector that head damping rotary connects, described damping connector is pipe box shape parts, circumference on the inwall of damping connector
Distribution is provided with the draw-in groove of several depression, and union joint is tubular part, and on the outer wall of union joint, projection is provided with and is connected with damping
The card article that the draw-in groove of part matches, described card article and draw-in groove clamping.
As the improvement of technique scheme, described card article is provided around groove on union joint, card article be connected
Head elastically deformably connects.
Further as technique scheme is improved, described card article semicircular in shape or arc, described damping connector
Draw-in groove corresponds to semicircle or arc, and draw-in groove is along the impartial arrangement continuously of damping connector inwall.
Further, described union joint is provided with fastens the barb of described damping connector.
Further, the end face that described damping connector is relative with the hinge hole of described hinged seat is provided with depressed part, hinge
In the hinge hole of joint chair, corresponding described depressed part is provided with the limiting section of projection.
Further, described base is provided with the installing hole being fastenedly connected described hinged seat, is provided with bottom hinged seat
Join the plug of grafting installing hole.
Further, described plug cross section is class rectangle, and its three limit is right-angle side, is arc.
Further, to be plastic cement one-body molded for described damping connector and union joint.
The invention has the beneficial effects as follows: this tumbler is capable of desk lamp effect with damping in rotating course,
So that Table lamp structure also is able to nature location turning to diverse location, it is to avoid rotation naturally, and also allow for use process
In carry out angle adjustment and fix, very convenient.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the partial exploded view of mounting structure of the present invention;
Fig. 2 is the structural representation of union joint in the present invention;
Fig. 3 is the structural representation damping connector in the present invention;
Fig. 4 is the structural representation of hinged seat in the present invention.
Detailed description of the invention
With reference to Fig. 1, the tumbler of a kind of desk lamp of the present invention, hinged including on the lamp socket 1 for being arranged on desk lamp
Seat 2, and the union joint 32 being arranged on the lamp body 3 of desk lamp, described hinged seat 2 is provided with the hinge for hinged described union joint 32
Connecing hole, be provided with the damping connector 21 being connected with union joint 32 damping rotary in this hinge hole, union joint 32 is arranged on lamp body 3
Two ends, articulated section 31, articulated section 31 is connected by union joint 32 and described damping connector 21 and realizes switching part 31 and hinge
Joint chair 2 hinged.
As shown in Figures 2 and 3, described damping connector 21 is pipe box shape parts, circumference on the inwall of damping connector 21
Distribution is provided with the draw-in groove 212 of several depression, and described union joint 32 is tubular part, and on the outer wall of union joint 32, projection is provided with
The card article 321 matched with the draw-in groove 212 of damping connector 21, described card article 321 and draw-in groove 212 clamping, when union joint 32 turns
Time dynamic, card article 321 needs generation subtle flow to move to another draw-in groove 212 by it, thus between card article 321 and union joint 32
Producing the abutting of interference fit, therefore form damping, additionally card article 321 and draw-in groove 212 can along hinge axes or pivot center
Axially or radially arrange.
As the improvement of above-mentioned embodiment, described card article 321 is provided around groove, card article on union joint 32
321 are elastically deformably connected with union joint 32.
Described card article 321 semicircular in shape or arc, the draw-in groove 212 of described damping connector 21 corresponds to semicircle or arc
Shape, and draw-in groove 212 is along the impartial arrangement continuously of damping connector 21 inwall, thus form the structure of impartial adjustable angle.
Being provided with the barb 322 fastening described damping connector 21 on described union joint 32, described barb 322 is from damping even
Passing and fasten damping connector 21 end face inside fitting 21, damping connector 21 is axially connected with union joint 32, and pass through
Hinged seat 2 limits the rotation of damping connector 21, so that union joint 32 angle adjustable rotates.
As shown in Figure 3 and Figure 4, the end face that described damping connector 21 is relative with the hinge hole of described hinged seat 2 is arranged
Having depressed part 211, in the hinge hole of hinged seat 2, corresponding described depressed part 211 is provided with the limiting section 22 of projection.
With reference to Fig. 1, described base 1 is provided with the installing hole being fastenedly connected described hinged seat 2, arranges bottom hinged seat 2
There is the plug 23 of coupling grafting installing hole.
Seeing Fig. 4, described plug 23 cross section is class rectangle, and its three limit is right-angle side, is arc so that it is be easier to guide
Insert.
Described damping connector 21 and union joint 32 are each that plastic cement is one-body molded to be made, and it has the most elastic change
Shape characteristic, is more suitable for angle modulation and rotates.
The above, the simply better embodiment of the present invention, but the present invention is not limited to above-described embodiment, as long as
It reaches the technique effect of the present invention with any same or similar means, all should fall under the scope of the present invention.
