Description

A kind of adjustable desk lamp

Technical field

The utility model relates to a kind of desk lamp, particularly a kind of adjustable desk lamp.

Background technology

Desk lamp is extensively applied in daily life, the working and learning, for easy to use, some products occurred, can adjust the illumination direction and the illumination zone of desk lamp.This type of product section is to take following structure in the market: pivot to connect connecting rod on Desk lamp feet, small end connects swivel, is connected on the swivel lampshade is rotating.Pitching by rotary lampshade and adjustment connecting rod realizes adjusting the illumination direction of desk lamp and the function of scope.

In actual use, the said goods comes with some shortcomings.At first, because lampshade shell is plastic products, rigidity is not enough, after date when using a section, and the connecting portion easy deformation of lampshade and swivel, cracking, even damage, cause desk lamp to use.

Secondly, do not have stopping means between lampshade and the connecting rod, easily because the lampshade rotation excessively causes the lamp line kinking, form potential safety hazard during use.

In addition, because long-term movable part wearing and tearing, stiction supports lampshade inadequately between two swivels, and it is sagging to cause lampshade can't fix because of the gravity effect, and influence is used.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provide a kind of more reasonable structure, reliability higher, do not allow flimsy adjustable desk lamp.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of adjustable desk lamp, comprise base, pivot on the base and be connected with connecting rod, the upper end of connecting rod is connected with the lateral rotation joint, the front end of lateral rotation joint is connected to vertical swivel, vertically the front end of swivel is connected with lampshade, is fixedly connected with the metal liner frame in the lampshade, and vertical swivel passes the metal liner frame and is connected with it.

In addition, be respectively arranged with projection and catch on this vertical steering knuckle He on the corresponding position of lampshade.

Also have, be with torsion spring on the connecting pin between the lateral rotation joint of this adjustable desk lamp and the vertical swivel, the torsion spring two ends respectively with vertical swivel and lateral rotation joint butt, make vertical swivel have certain tip-tilted elastic force.

The beneficial effects of the utility model are:

Adopt such structure, in use the metal liner frame is main stressed member, and Table lamp structure is more firm, and reliability is higher, is not easy to damage.

In addition, projection on lampshade and the vertical swivel and catch play position-limiting action to the anglec of rotation of lampshade, prevent that effectively the lampshade rotation is excessive and cause the lamp line kinking.

Also have, the torsion spring two ends that connect on the bolt of two steering knuckles are connected to respectively on two swivels, and lampshade is played certain supporting role, have avoided lampshade because of the sagging phenomenon of gravity effect, have effectively overcome deficiency in the past.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the stereoscopic figure of adjustable desk lamp of the present utility model;

Fig. 2 is the structural representation of the utility model desk lamp;

Fig. 3 is the part-structure schematic diagram of the utility model desk lamp.

The specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, the utility model comprises base 7, pivot on the base 7 and be connected with connecting rod 11, the upper end of connecting rod 11 is connected with lateral rotation joint 3, the front end of lateral rotation joint 3 is connected to vertical swivel 2, and an end of lampshade 1 is rotatably connected on the front end of vertical swivel 2, and bulb socket 13 is installed in the lampshade 1, be fixedly connected with metal liner frame 8 in the lampshade 1, vertical swivel 2 passes metal liner frame 8 and is connected with it.

As preferred version of the present utility model, the metal liner frame 8 of this example is made of the left plate 82 and the right plate 83 of

base plate

81,81 liang of lateral bucklings of base plate, fixedlys connected with lower lamp shade 15 with upper lamp shade 14 respectively in the upper end 87 of base plate 81, lower end 88; Porose 84 on the base plate 81 of metal liner frame 8, vertically swivel 2 passes hole 84 and is connected with metal liner frame 8.

The left plate 82 of metal liner frame 8 and right plate 83 tops have

brace

85,86 respectively, and

brace

85,86 is fixedlyed connected with upper lamp shade 14, and bulb socket 13 is fixedly connected on the

brace

85,86.

Vertical swivel 2 of this example is to be made of Connection Block 21 and baffle plate 22, and Connection Block 21 front ends pass lampshade 1 housing, metal liner frame 8 is fixedlyed connected with baffle plate 22; Projection 4 is arranged on the baffle plate 22, be equipped with

catch

5,6 in lampshade 1 corresponding positions, this example is arranged on

catch

5,6 on the metal frame 8; The slewing area of this structure qualification lampshade prevents that the lampshade rotation from excessively causing the lamp line kinking.For making, on vertical duction joint and the baffle plate 7 pin and pin-and-hole are arranged respectively in conjunction with more fastening.

Vertically articulate by connecting pin 10 between swivel 2 and the lateral rotation joint 3, connecting pin 10 1 sides are connected with nut cap 12.Torsion spring 9 is installed on the connecting pin 10, torsion spring 9 two ends respectively with vertical swivel 2, lateral rotation joint 3 butts, form certain torsion, prevent that lampshade 1 from using because of the sagging influence of gravity effect.

Certainly; the projection between the utility model lampshade and vertical swivel and the setting of catch also can be adopted other structure; as projection is placed on the lampshade, catch is placed on vertical swivel or the like, such conversion all drops within the protection domain of the present utility model.
