SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problem that the later taking-off and maintenance difficulty of a screen cloth is increased by fixing a screen cloth rolling device on a wall surface when the screen cloth is used in the prior art, and provides a multimedia teaching projection screen cloth fixer.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a multimedia teaching projection curtain fixer, includes movie screen cloth winding device body, fixed plate, the fixed block is all installed to movie screen cloth winding device body top both sides, two the interval sets up between the fixed block, two the spout has all been seted up to the both sides of fixed block, two the fixed block both sides all slide on the spout and be provided with the draw runner, two the fixed block both sides the draw runner relative outside all welds there is the fixed strip, two the fixed block both sides the fixed strip all welds in on the fixed plate, two a plurality of fixed orificess have all been seted up on the fixed plate, two the fixed strip is kept away from fixed plate one end is all installed the card and is established the mechanism, the card establish the mechanism with be provided with the spring between the fixed block.

Preferably, the clamping mechanism comprises a clamping groove formed in the fixing strip, clamping blocks are arranged on two sides of the clamping groove formed in the fixing strip, magnets are arranged on the inner sides of the clamping blocks, and the magnets are arranged between the sliding strips at intervals.

Preferably, two slide bars are installed on one side of each fixing plate, and the slide bars penetrate through the fixing blocks and the springs in a sliding mode and are abutted to the magnets.

Preferably, the two fixing blocks are provided with hanging holes.

The multimedia teaching projection curtain fixer has the beneficial effects that: this multimedia teaching projection curtain fixer runs through the fixed orifices through the bolt and fixes the fixed plate on the wall, lets the fixed block on the shadow curtain winding device body slide and sets up on the draw runner, and at this moment the slide bar runs through the fixed block, establishes the spring housing on the slide bar, establishes the block of mechanism through the card, lets spring one end butt in the one side of card establishment mechanism, and the other end of spring is to the fixed block atress to let the installation of shadow curtain winding device body steady. When the screen cloth rolling device body needs to be maintained, the screen cloth rolling device body slides off the sliding strip through the clamping mechanism, so that the maintenance is convenient.

Fig. 2 is a partial enlarged view of fig. 1 at a.

Fig. 3 is an exploded view (enlarged) of a part of the structure of a multimedia teaching projection curtain holder according to the present invention.

In the figure: the film curtain cloth rolling device comprises a film curtain cloth rolling device body 1, a fixing block 2, a sliding chute 3, a sliding strip 4, a fixing strip 5, a fixing plate 6, a fixing hole 7, a spring 8, a clamping groove 9, a clamping block 10, a magnet 11, a sliding rod 12 and a hanging hole 13.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-3, a multimedia teaching projection curtain fixer comprises a curtain cloth rolling device body 1 and fixing plates 6, wherein fixing blocks 2 are fixedly arranged on two sides of the top of the curtain cloth rolling device body 1, the two fixing blocks 2 are arranged at intervals, hanging holes 13 are respectively arranged on the two fixing blocks 2 (the curtain cloth rolling device body 1 can be hung through the hanging holes 13, so as to provide another installation mode), sliding grooves 3 are respectively arranged on two sides of the two fixing blocks 2, sliding strips 4 are respectively arranged on the sliding grooves 3 on the two sides of the two fixing blocks 2 in a sliding manner, fixing strips 5 are respectively welded on the opposite outer sides of the sliding strips 4 on the two sides of the two fixing blocks 2, the fixing strips 5 on the two sides of the two fixing blocks 2 are respectively welded on the fixing plates 6, a plurality of fixing holes 7 are respectively arranged on the two fixing plates 6, and a clamping mechanism is respectively arranged at one end of the two fixing strips 5, which is far away from the fixing plates 6, be provided with spring 8 between card establishment mechanism and the fixed block 2, the equal fixed mounting in two fixed plate 4 one sides has slide bar 12, slide bar 12 all slides and runs through fixed block 2,

spring

8 and 11 looks butt with magnet, the card is established the mechanism and is including seting up draw-in groove 9 on fixed strip 5, fixture block 10 is all installed to the draw-in groove both sides on two fixed strips 5, magnet 11 is all installed to the relative inboard of two fixture blocks 10, magnet 11 and draw-in strip 4 between the interval set up (set up here magnet 11 and draw-in strip 4 between the interval set up to avoid spring 8 to place inconveniently, spring 8 is the cover to be established on slide bar 12, spring 8's both ends are respectively to fixed block 2, magnet 11 atress.
