Abstract

The utility model discloses a portable blank angle modulation control structure, including fixing left and right rotation axis and the carousel on the blank, fixing the bolt subassembly on the support, there is the circumference hole on the carousel, and the bolt subassembly includes sleeve, spring, bolt, handle, and the sleeve is fixed on the support, is provided with the spring in the sleeve, is provided with the bolt in the spring, and the handle is fixed at the bolt tail end. Through fixing the carousel on the blank and fixing the bolt on the support, can be simple, quick completion blank angle modulation to there is the dual location of pivot and toper bolt, can stably fix the blank, avoid the blank to rock on the support, satisfy writer and viewer's demand simultaneously, improve exchange efficiency.

Description

Portable blank angle modulation control structure

Technical Field

The utility model relates to a movable whiteboard device, especially a movable whiteboard angle control structure.

Background

The movable whiteboard is a white writing plane, is a writing tool capable of being erased and written repeatedly, is generally used for teaching, conference discussion, personal note keeping and the like, and in the traditional technology, the whiteboard is mostly fixed on a whiteboard bracket for use, so that the whiteboard can meet the use requirements of general conditions, but the whiteboard is fixed in angle, and the whiteboard is difficult to meet the market requirements for watching and writing, so that the applicability and the practicability are limited. For example, chinese utility model patent publication No. CN205970484U discloses a "movable whiteboard", which realizes the movement and fixation of the whiteboard through a foot brake installed at the bottom of the support. The whiteboard can only solve the problem of the visual angle of a viewer by moving, needs a larger moving space, does not consider the writing requirement of a writer, and influences the watching and communication effects.

SUMMERY OF THE UTILITY MODEL

In order to overcome among the prior art defect such as blank angle can not be adjusted or adjust inconvenience, the utility model provides a portable blank angle modulation control structure carries out angle modulation to the blank, through fixing the carousel on the blank and fixing the bolt on the support, and accomplish the angle modulation to the blank.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a portable blank angle modulation control structure, is including fixing left and right rotation axis and the carousel on the blank, fixing the bolt subassembly on the support, has the circumference hole on the carousel, and the bolt subassembly includes sleeve, spring, bolt, handle, and the sleeve is fixed on the support, is provided with the spring in the sleeve, is provided with the bolt in the spring, and the handle is fixed at the bolt tail end.

In the angle adjustment control structure for the movable whiteboard, the left rotating shaft and the right rotating shaft are positioned at the center positions of the two sides of the whiteboard, and the whiteboard is connected with the bracket through the rotating shafts; the turntable is circular and is fixed on the side edge of the whiteboard, and the center of the turntable passes through the whiteboard rotating shaft; the bolt component is fixed on the bracket through the sleeve; the front end of the bolt is conical, and the bolt is arranged in the sleeve; the spring is arranged between the bolt and the bracket; the handle is arranged outside the bracket.

In the angle adjustment control structure of the movable whiteboard, the bolt moves in the sleeve through the handle, and the bolt resets in the sleeve through the spring; the front end of the bolt is conical, and when the bolt enters the circumferential hole of the turntable, the bolt is completely overlapped, so that the shaking is reduced, and the stability is improved; when the angle of the whiteboard is adjusted, the handle is pulled outside the support, the bolt is separated from the rotary table, the handle is loosened after the whiteboard is rotated, and the bolt enters the circumferential hole of the rotary table to complete the angle adjustment.

The beneficial effects of the utility model are that, the utility model discloses the pulling handle rotates the blank, can be simply, quick completion blank angle modulation to have the dual location of rotation axis and toper bolt, can stabilize fixed blank, avoid the blank to rock on the support, satisfy the demand of writing person and viewer simultaneously, improve exchange efficiency.

Drawings

The present invention will be further explained with reference to the drawings and examples.

FIG. 1 is a schematic view of the present invention;

FIG. 2 is a first schematic structural diagram;

FIG. 3 is a second schematic structural diagram;

in the figure, 1 is a white board, 2 is a handle, 3 is a bracket, 4 is a rotating disc, 5 is a rotating shaft, 6 is a sleeve, 7 is a bolt, and 8 is a spring.

Detailed Description

And pulling the handle along the outer side of the support to separate the bolt from the turntable, loosening the handle after rotating the white board, and enabling the bolt to enter the circumferential hole of the turntable under the action of the spring to complete angle adjustment.

Claims
