Accompanying drawing explanation
Fig. 1 is the side-looking structural representation of the utility model multi-functional blackboard exhibition cabinet;
Fig. 2 is the backsight structural representation of the utility model multi-functional blackboard exhibition cabinet.
Number in the figure represents: 1-curtain reel, 2-rectangular cabinet, 3-gear band, 4-gear, 5-" X " type support, 6-linear slide track, 7-blackboard, 8-ball, 9-retainer ring, 10-spring, 11-telescopic stand, 12-leading screw.
The specific embodiment
As shown in Figure 1, 2, the utility model is a kind of multi-functional blackboard exhibition cabinet, comprises rectangular cabinet 2, blackboard 7 and retractor device.Concrete:
The front end of rectangular cabinet 2 opens wide, corresponding blackboard 7 coordinates this front opening to install, the top of blackboard 7 and bottom are provided with ball 8, the top board lower surface of the corresponding rectangular cabinet 2 of difference and the upper surface of base plate, and Convenient blackboard 7 moves forward and backward along the top board lower surface of rectangular cabinet 2 and the upper surface of base plate.In this specific embodiment, the front opening place of rectangular cabinet 2 is provided with the stopping means of blackboard 7.
Retractor device comprises telescopic stand 11, " X " type support 5, leading screw 12, gear 4 and gear band 3.Wherein: " X " type support 5 one end are fixedly connected on telescopic stand 11, the other end is provided with slide block, corresponding blackboard 7 back sides are provided with corresponding linear slide track 6.On telescopic stand 11, be provided with screwed hole, the installation of leading screw 12 engagements and be connected leading screw 12.Gear 4 is fixedly mounted on leading screw 12 bottoms and leading screw 12 and is arranged on this gear 4 and takes turns on direction of principal axis, and in this specific embodiment, gear 4 and leading screw 12 are overall structure.Gear band 3 is connected with a joggle on gear 4, and its two ends and rectangular cabinet 2 removably connect.In this specific embodiment, the madial wall that gear band 3 one end installations are connected with spring 10, spring 10 ends and rectangular cabinet 2 removably connects.The other end of gear band 3 is detachably connected on cabinet, specifically on the opposite side bottom outside wall of rectangular cabinet 2 length directions, is provided with retainer ring 9, and gear band 3 ends are provided with hook, removably connect with retainer ring 9.When gear band 3 two ends are all connected with rectangular cabinet 2, spring 10 is while being stretched to maximum position, the position correspondence of blackboard 7 is contracted on rectangular cabinet 2 widths, innermost position.
Rectangular cabinet 2 front top are provided with curtain reel 1 along its length, for curtain or the transparent cord of projecting apparatus are installed, can put down and coordinate projecting apparatus or the dustproof use of affected displaying while needing.
In the time of need to moving forward and backward blackboard 7 of the present utility model, pull gear band 3, gear 4 is rotated, for integrally-built leading screw 12, synchronize rotation with gear 4, thereby telescopic stand 11 is moved forward and backward on leading screw 12, make " X " type support 5 on width, compress or stretch.Because " X " type support 5 front ends are designed with up and down slide block, can move in opposite directions or oppositely in the linear slide track on blackboard 7 back sides, thereby regulate the position of blackboard 7 in rectangular cabinet 2.
