Fig. 1-4 is please referred to, the present invention provides a kind of technical solution:

A kind of Liftable type bracket, including bottom plate 1, the lower end of bottom plate 1 are bolted there are four trundle 10, this reality It applies in example, trundle 10 is screwed stabilization when being conducive to integral support work in the four corners of 1 lower end of bottom plate respectively Property and it is easy under the effect of external force move bracket.

The upper end of bottom plate 1 has been screwed telescopic mast 2, and the telescopic mast 2 in the present embodiment can use Guangzhou high official position The bamboo joint type lifting column that the product type of video device Co., Ltd production is R06-1000, matched circuit and power supply It is provided by the producer；In addition, the circuit and electronic component and module that are related in the present invention are the prior art, this field Technical staff may be implemented completely, and details are not described herein, and the content that the present invention protects is not related to changing for software and method yet Into.

The top of telescopic mast 2 has been bolted connection frame 31, and placing frame 3, placing frame 3 are equipped on connection frame 31 Inner wall is welded with wire netting 30 close to the position of upper end, convenient for a part of projector lower end to be limited in placing frame 3, places Horizontal looseness, and be placed on wire netting 30, to achieve the effect that radiate to it when projector works.

In the present embodiment, connection frame 31 is in cross, and its middle-end is fixedly connected with telescopic mast 2, and four ends are respectively welded In 3 inner wall of placing frame close to the position of lower end, telescopic mast 2 can be fixedly connected with placing frame 3 by connection frame 31, to make Telescopic mast 2 drives placing frame 3 to move up and down.

The outer wall two sides of placing frame 3 pass through rivet respectively and are fixed with an elastic band 4, and in the present embodiment, elastic band 4 is distinguished It is screwed and leans on the position of proximal edge in 3 upper end of placing frame, and about the output end of telescopic mast 2 bilateral symmetry, be conducive to Projector is fixed on the wire netting 30 in placing frame 3.It is worth noting that elastic band 4 is made of elastic material, just It stretches under external force in elastic band 4, to achieve the effect that tighten projector.

In the present embodiment, wherein an elastic band 4, which is located remote from one end of frame 3, is fixed with card case 5 by rivet, another One end that elastic band 4 is located remote from frame 3 is fixed with fixture block 6 by rivet, and the upper and lower surface of fixture block 6 is respectively welded a spring 60, and two springs 60 are symmetrical above and below about fixture block 6, spring 60 is respectively welded long handle 61, long handle far from one end of fixture block 6 61 one end far from spring 60 are respectively welded convex block 62, and convex block 62 is corresponding with the position of spring 60 respectively, pass through long handle 61 Pressing spring 60 can be easily pressed, so that convex block 62 is driven to move down, and convex block 62 can be in the work of spring 60 after losing external force Original position is returned under, achievees the effect that convex block 62 moves up and down with this.Fixture block 6 can be inserted into card case 5, and card case 5 Hole is opened up respectively with the corresponding position of convex block 62, and convex block 62 and hole are engaged by clamping, and are each passed through hole convenient for convex block 62 Hole makes fixture block 6 and card case 5 be engaged by clamping, to achieve the effect that connect two elastic bands 4.

The outer wall front end of placing frame 3 has been bolted handle 32, and holding handle 32 easily can move or adjust The angle of integral support.

Four trundles 10 when in use, are first separately mounted to the four of 1 lower end of bottom plate by Liftable type bracket of the invention At angle, then pass through the upper end that telescopic mast 2 is fixed on bottom plate 1 by screw, connection frame 31 and wire netting 30 are respectively welded at placement After on frame 3, the output end of telescopic mast 2 is fixed by bolts in the middle end position of the lower section of connection frame 31, then with rivet by two Bar elastic band 4 is screwed respectively in the upper end of 3 left and right sides of placing frame, wherein being located at the elastic band 4 in left side far from putting The one end for setting frame 3 is fixedly connected with card case 5, and one end that the elastic band 4 for being located at right side is located remote from frame 3 is fixed with by rivet The fixture block 6 that spring 60 is welded at both ends is descended on it, wherein spring 60 is respectively welded long handle far from one end of fixture block 6 61, and long handle 61 is respectively welded convex block 62 far from one end of spring 60, and the outer wall in placing frame 3 is fixedly arranged at the front end with handle 32。

Projector can be placed on wire netting 30 when use, then simultaneously press two long handles 61 make spring 60 respectively to Fixture block 6 compresses, to make the hypotelorism of two convex blocks 62, fixture block 6 can be made to protrude into the inside of card case 5 with this, convex block 62 is divided Not and after the hole aligning on card case 5, long handle 61 is unclamped, spring 60 restores to the original state after losing external force, to drive on convex block 62 It moves, so that the hole on convex block 62 and card case 5 is engaged by clamping, projector is fixed on wire netting 30 by elastic band 4 with this, hand Handle 32 can easily move bracket or change the direction of placing frame 3 according to the wish of user, to change projector Projecting direction to watch, connect the power supply of telescopic mast 2, make its work, telescopic mast 2 stretches, thus to projector Height is adjusted, and need to only press long handle 61 when removing projector simultaneously separates convex block 62 with the hole on card case 5, while band Dynamic fixture block 6 is detached from card case 5, two elastic bands 4 can be made to separate, to remove projector.

The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry For personnel it should be appreciated that the present invention is not limited to the above embodiments, described in the above embodiment and specification is only the present invention Preference, be not intended to limit the invention, without departing from the spirit and scope of the present invention, the present invention also has various Changes and improvements, these changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by institute Attached claims and its equivalent thereof.
