Abstract

The utility model discloses a folding rod table lamp, which is characterized in that: a corner butt hinge is adopted at the corner of the lamp post; a smooth surface rubber cushion made of silica gel is clamped in between a fixed axle bush that fixes the lower lamp post and a movable axle bush that fixes the upper lamp post; spring is compressed under a nut; the three above-mentioned elements are arranged in coaxial direction and are fixed with bolts and nuts, so that the corner butt hinge will keep certain drag force and the lamp base will not droop automatically after the utility model has been in use for a long time.

Description

Desk lamp

Technical field

The utility model relates to a kind of desk lamp, relates in particular to a kind of pole formula desk lamp.

Background technology

The present pole formula desk lamp that uses, its corner hinge is the steel hinge, the lamp stand turnover is dumb loosening easily again, makes lamp holder sagging, influences normal illumination.

Summary of the invention

The utility model provides a kind of pole formula desk lamp, and its corner hinge rotates flexibly, has good corner stiffness again, uses lamp holder also can not need often to adjust trip bolt because of sagging automatically for a long time.

In order to solve the problems of the technologies described above, the utility model is realized with following technical scheme: a kind of desk lamp, comprise the lamp socket 13 that fluorescent tube is installed, many folding lamp stands 15,16,3, lamp holder 1 that corner hinge 4 is connected with the lamp stand end and power line 12, switch 14, it is characterized in that: the corner hinge 4 that adjacent two joint lamp stands connect, comprise the dead axle cover 11 that is vertically mounted on down fluorescent tube 15 upper ends, be vertically mounted on the moving axis cover 5 of fluorescent tube 16 lower ends and be installed in dead axle cover 11 and be installed in three's the centre bore with the rubber cushion 9 usefulness screws 7 that moving axis overlaps in the middle of 5, the terminal pocketed springs 8 of screw 7, the nut 6 that matches with screw will move, the dead axle cover compresses.

The utility model has the advantages that, between two axle sleeves of adjacent lamp stand, clamp the rubber cushion that silicon rubber is made, press-fit spring on trip bolt, when nut is screwed to a certain degree, the spring pressurized produces strain potential energy, the rubber cushion pressurized becomes the strain of giving birth to, the both has guaranteed between the two lamp axle sleeves certain thrust is arranged, and the end face of rubber cushion is smooth, and friction increases between two adjacent axle sleeves, make it lamp stand and not only rotate flexibly, remain certain frictional force again and prevent that lamp holder is sagging.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the structural representation of desk lamp;

Fig. 2 is the A-A profile of Fig. 1.

Among the figure: 1, lamp holder, 2, the lamp holder extension bar, 3, lamp stand, 4, the corner hinge, 5, the moving axis cover, 6, nut, 7, screw, 8, spring, 9, rubber cushion, 10, head of screw, 11, the dead axle cover, 12, power line, 13, lamp socket, 14, switch, 15, lamp stand, 16, lamp stand.

The specific embodiment

As shown in Figure 1 and Figure 2, power line 12 and switch 14 are installed on the lamp socket 13, the lower end of lamp stand 15 is fixed on the top of lamp socket 13, and the upper end of lamp stand 15 is connected with the lower end of lamp stand 16 by corner hinge 4; The lower end of the upper end of lamp stand 16 and lamp stand 3, the upper end of lamp stand 3 and all pass through corner hinge 4 being connected of lamp holder extension bar 2 and realize.

Corner hinge as shown in Figure 2, overlap 5 coaxial installations with the dead axle cover 11 that saves lamp stand upper end vertical fixing down with last one moving axis that saves lamp stand lower end vertical fixing, clamp rubber cushion 9 between the two, install screw 7 between the three in the hole, press-fit spring 8 usefulness nuts 6 three is pressed to suitable degree, owing to produce certain elastic potential energy during spring 8 pressurizeds, rubber cushion 9 is made for silicon rubber, has better elastic, surface that the rubber cushion two ends are smooth and adjacent sleeve end mask have bigger coefficient of friction, adjust the elasticity of nut, the corner hinge is by the elastic potential energy of spring and the elasticity of rubber cushion, remain the corner resistance of corner hinge, make lamp holder can not use not saggingly automatically because of long-term, and corner be flexible.
