Description

A kind of Educational Affairs Office teaching demonstration device

Technical field

This utility model relates to a kind of teaching aid, specifically a kind of Educational Affairs Office teaching demonstration device.

Background technology

The teaching in Educational Affairs Office often relates to some exhibiting devices, such as Graphic Panel, show stand etc., these devices Can show, for student's door, some teaching knowledges that finish writing in advance easily, can by emphasis knowledge induction and conclusion, To facilitate student to take down notes and to remember, but existing Graphic Panel takes up space, area is big, is unfavorable for teacher Operation, function is the most single, give teaching process make troubles, and when sometimes teacher imparts knowledge to students because The difference of class, the size of its class would also vary from, and such whole process all uses same Graphic Panel the most not Convenient, as big class, because its number is many, space, classroom is big, not only needs Graphic Panel sufficiently large, also Need Graphic Panel sufficiently high, the classmate sat in the back row can be made to can also be seen that, but this means that The structure of this kind of Graphic Panel wants more relative complex, and little class and classroom are the most relatively small, if also Use the Graphic Panel of lyceum, the most relatively carry trouble, and some function takes less than, and causes at all The wasting of resources.

Utility model content

The purpose of this utility model is to provide a kind of Educational Affairs Office teaching demonstration device, to solve above-mentioned background skill The problem proposed in art.

For achieving the above object, the following technical scheme of this utility model offer:

A kind of Educational Affairs Office teaching demonstration device, including framework, is provided with board, the end of framework in described framework Portion is arranged on support platform, and the bottom supporting platform connects telescopic supporting rod by level(l)ing device, and level is adjusted Regulating device is hinged with support platform lower end, and described telescopic supporting rod lower end is vertically set on base, base lower end It is provided with castor；Two edge of described framework are provided with standpipe, are provided with vertical rod, the side in standpipe in standpipe Longitudinally being provided with blind hole on tube wall, be provided with disc spring in blind hole, the termination of disc spring is provided with ball, and the lower end of vertical rod sets There are the fixing hole matched with ball, the tube wall of standpipe opposite side to be provided with gap, in gap, are provided with handle, One end of handle is connected with vertical rod, and the top of vertical rod is provided with crossbeam, and the front surface of crossbeam is connected by spring to be had Blend stop, one end of crossbeam front surface is hinged with press strip by rotating shaft, and magnet piece and crossbeam are passed through in the termination of press strip The other end of front surface connects.

As further program of the utility model: described level(l)ing device includes two pieces of gripper shoes and two Adjusting rod, length adjusting rod two ends that are identical and that be arranged in parallel are hinged with gripper shoe respectively and form parallel four Limit shape structure.

As this utility model further scheme: described blend stop is provided with anti-slip veins with the contact surface of press strip.

Compared with prior art, the beneficial effects of the utility model are: this utility model simple in construction, use Convenient, framework can be applied in combination with supporting platform, and telescopic supporting rod can regulate the height of entirety, convenient sight Seeing, being moved easily framework, framework can also be used alone, and self also has height adjusting function, Ke Yi little The regulation height of scope, allomeric function is various, easy to use.

Accompanying drawing explanation

Fig. 1 is the structural representation of Educational Affairs Office teaching demonstration device；

In figure: 1-framework, 2-board, 3-support platform, 4-gripper shoe, 5-adjusting rod, 6-control knob, 7-telescopic supporting rod, 8-base, 9-castor, 10-standpipe, 11-vertical rod, 12-disc spring, 13-ball, 14- Fixing hole, 15-gap, 16-handle, 17-crossbeam, 18-spring, 19-blend stop, 20-rotating shaft, 21-pressure Bar, 22-magnet piece.

Detailed description of the invention

Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.

Refer to Fig. 1, a kind of Educational Affairs Office teaching demonstration device, including framework 1, in framework 1, be provided with board 2, the bottom of framework 1 is arranged on support platform 3, and the bottom supporting platform 3 is stretched by level(l)ing device connection Contracting support bar 7, level(l)ing device is hinged with support platform 3 lower end, and level(l)ing device includes two pieces of supports Plate 4 and two adjusting rods 5, length is identical and adjusting rod 5 two ends that be arranged in parallel respectively with gripper shoe 4 phase Hinged and form parallelogram sturcutre, described telescopic supporting rod 7 lower end is vertically set on base 8, the end Seat 8 lower ends are provided with castor 9；Two edge of described framework 1 are provided with standpipe 10, are provided with vertical in standpipe 10 Bar 11, the side tube wall in standpipe 10 is longitudinally provided with multiple blind hole, is provided with disc spring 12, disc spring in blind hole The termination of 12 is provided with ball 13, and the lower end of vertical rod 11 is provided with the fixing hole 14 matched with ball 13, vertical The tube wall of pipe 10 opposite side is provided with gap 15, is provided with handle 16 in gap 15, one end of handle 16 with Vertical rod 11 connects, and the top of vertical rod 11 is provided with crossbeam 17, and the front surface of crossbeam 17 is connected by spring 18 Having blend stop 19, one end of crossbeam 17 front surface is hinged with press strip 21, the termination of press strip 21 by rotating shaft 20 Being connected by the other end of magnet piece 22 with crossbeam 17 front surface, described blend stop 19 contacts with press strip 21 Face is provided with anti-slip veins.

Operation principle of the present utility model is: when using as entirety, is placed in by framework 1 on support platform 3 End, can regulate the height of telescopic strut 7 according to demand, then select suitably height, when supporting platform 3 When causing framework 1 not level because of the base of bottom 8 not level, adjust support platform by control knob 6 The levelness of 3；If the most simply needing the most small-sized teaching, can be by framework 1 from supporting platform 3 On take off, be placed on lectern, Graphic Panel be attached on blend stop 19, make press strip 21 be pressed in by rotating shaft 20 On Graphic Panel, one end of press strip 21 is bonded by magnet piece 22 with one end of crossbeam 17, and spring 18 is with anti- The design of sliding stricture of vagina, makes blend stop 19 more fasten with press strip 21 and is clamped by Graphic Panel.By the tension force of disc spring 12, Ball 13 is stuck in fixing hole 14, upwardly handle 16, and the fixing hole 14 in vertical rod 11 blocks and next Individual ball 13 combines, and adds the vertical rod 11 height in standpipe 10, the simultaneously Graphic Panel on crossbeam 17 Height increase, facilitate the viewing of student, vertical rod 11 can be fully retracted in standpipe 10 after using, root Height according to Graphic Panel is different, can arbitrarily regulate the length of vertical rod 11, it is to avoid the lower section of Graphic Panel is too low, learns Raw viewing less than；Also can vertical rod 11 be used together with retractable support 7, the height making Graphic Panel is bigger simultaneously.

Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned reality Execute mode, in the ken that one skilled in the relevant art is possessed, it is also possible to without departing from this specially Make a variety of changes on the premise of profit objective.
