Abstract

A posture-fixing backlit reading lamp for students consists of a lifting pole, a posture-fixing jaw seat, a lamp holder, a coil pipe, a lampshade and a fastening rack. A switch is arranged in the posture-fixing jaw seat and a runner fixed and arranged at the bottom of the lamp holder can adjust the back-front distance on a sliding block. The lifting pole on a fixed pole can adjust the height of the posture-fixing jaw seat. The lampshade can adjust the proper backlight distance up and down or to and fro. When in application, a student can place his or her lower jaw on the posture-fixing jaw seat, a distance of over 33 centimeters is kept between the eyes and the book and the backlight can avoid direct irradiation into the eyes by light. The utility model is simple in structure, and can work to restrict postures definitely and avoid irradiation from dazzling light.

Description

Decide appearance backlight type student and use desk lamp

The utility model relates to a kind of desk lamp, particularly a kind ofly decides appearance backlight type student and uses desk lamp.

The decline of student eyesight, except that innate factor, most relevant with read-write posture, lighting angle and light power.In order to effectively prevent the decline of student eyesight, the product of constraint pupil reading and writing posture arises at the historic moment, as " the multi-functional read-write desk lamp " patent No. 94212283.6, be to constitute by elevating lever, the lamp socket that dovetail matches and the lampshade that is fixed on the elevating lever that dovetail matches, though it adopts mode backlight to throw light on and jaw holder constraint posture, it still has the following disadvantages:

1, the elevating lever and the holder structure complexity that match of dovetail, difficulty of processing is big, production cost is higher, be unfavorable for popularizing.

2, fluorescent tube and corresponding lampshade are to be fixed on the elevating lever, and lighting angle is restricted, if adjust suitably height, the jaw holder is highly also influenced, and both are difficult for taking into account.

3, adjust before and after the dovetail lamp socket is difficult for, excesssive gap, light fixture and jaw holder shakiness influence pupil reading and writing, and the gap is too small, is difficult for before and after the lamp socket adjusting.

4, ballast places in the lamp socket, and the student is near the desk lamp read-write, and the 220V power supply is unfavorable for student's safety.

The purpose of this utility model will provide a kind of exactly decides appearance backlight type student and uses desk lamp, and its simplifies lifting structure and lamp socket is laterally adjusted structure, thereby reduces production costs, and the lighting angle adjustment is flexible, is not subjected to the constraint of elevating lever height; Outer formula ballast is put in employing, and is safe in utilization.

The technical solution of the utility model is achieved in that deciding appearance backlight type student uses desk lamp, comprises lampshade, posture fixing jaw base, coiled pipe, elevating lever, fixed bar, lamp socket, fastening frame, switch, resilience switch, ballast.One end of coiled pipe connects with lampshade, and lamp socket is provided with switch, and the effect of this switch is to do common desk lamp and uses.Fluorescent tube is installed in the lampshade, and by the switch in lead and the lamp socket, starter, place lamp socket outer ballast, attaching plug to link.Posture fixing jaw base is installed in the elevating lever upper end, and the lower end and the lamp socket of fixed bar are fixedly connected.Be processed with ratchet on the elevating lever, elevating lever and fixed bar matched in clearance are installed in the ratchet location engagement of ratchet on the fixed bar and elevating lever.The lamp socket bottom is installed with chute, slide block and chute matched in clearance, and the slide block mesopore cooperates with anchorage bar, and coiled pipe end in addition is fixedly connected with posture fixing jaw base, and the posture fixing jaw base middle part is provided with the resilience switch.

The utility model adopts pipe or square tube fixed processing bar, and with the elevating lever matched in clearance of respective shapes, lamp socket adopts chute and slide block to cooperate, and by the anchorage bar location, the production difficulty reduces, and production cost is also lower, during use, the lamp socket base fixed also is convenient to the adjustment of front and back position.Lampshade links by coiled pipe and posture fixing jaw base, not only can reach effect backlight, avoids the direct stimulation of light, and can adjust the backlight illumination angle in upper and lower, left and right.Ballast and plug connect together, and supply voltage becomes 12V by 220V, and the student can guarantee safety near the light fixture read-write time.

Below in conjunction with accompanying drawing the utility model is described further.

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

Fig. 2 is that A of the present utility model is to schematic diagram;

Fig. 3 is that B of the present utility model is to schematic diagram;

Fig. 4 is a lamp socket bottom sectional schematic diagram of the present utility model;

Fig. 5 is a pawl structures schematic diagram of the present utility model.

With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4.A kind ofly decide appearance backlight type student and use desk lamp, comprise lampshade 1, posture fixing jaw base 3, coiled pipe 2, elevating lever 4, fixed bar 5, lamp socket 6, fastening frame 9, switch 11, resilience switch 12, ballast 24.Coiled pipe 2 one ends and 1 firm connection of lampshade, end links with posture fixing jaw base in addition.Use for making the utility model can make common desk lamp, on lamp socket, be added with switch 11 especially, in the lampshade 1 fluorescent tube is installed, and, place lamp socket outer ballast 24, attaching plug to link by the switch in lead and the lamp socket.Posture fixing jaw base 3 is installed in elevating lever 4 upper ends, and the lower end of fixed bar 5 and lamp socket 6 are fixedly connected.Be processed with ratchet 16 on the elevating lever 4, elevating lever and fixed bar matched in clearance, the ratchet 17 that is installed on the fixed bar meshes with the ratchet location of elevating lever.Chute 20 fixedly is equipped with in lamp socket 6 bottoms, slide block 19 and chute matched in clearance, and slide block mesopore 23 cooperates with anchorage bar 7, during use, along 10 chuckings, one can make lamp socket laterally not move with table to make fastening frame 9 and slide block 19, chute 20 by wing nut, and two can make lamp socket 6 firmly on the table.

Be processed into to recessed cambered surface 13 top of posture fixing jaw base 3, in the cambered surface bottom resilience switch 12 is housed.In use, be lower than the height of setting right overhead, lower jaw will be pressed on the resilience switch, i.e. powered-down, and fluorescent tube extinguishes.When posture was correct, lower jaw promptly had certain distance with the resilience switch, and the resilience switch is upspring, and this moment is for connecting power supply, fluorescent light emitting tube.14 is lead among Fig. 2.The bottom of posture fixing jaw base 3 is by pipe box 15 and elevating lever end immovable fitting.

With reference to Fig. 5.Ratchet 17 places in the cover 22, between the cover shoulder and the ratchet shaft shoulder spring 21 is housed, and ratchet end in addition is an one with handle 18, pulling handle 18, and torsional direction can place open position.When the ratchet projection resets chute,, can make ratchet and ratchet 16 engagements by spring 21.

In use, earlier lamp socket is placed on the desktop edge, the back transfers to the one fist position from the table limit, tightening lamp socket then, and then with the suitable height of elevating lever adjustment, lower jaw is placed on the posture fixing jaw base, in principle, posture fixing jaw base adjustment height is advisable more than eye distance books one chi, so just meets school " three 1 " (promptly from table limit one fist, from books one chi, from the nib one-inch) correct read-write posture.Then lampshade being adjusted to suitable position backlight can normally use.
