Abstract
The invention relates to a portable and foldable drawing board support and an application method thereof. The portable and foldable drawing board support is composed of a right-angle and 'L'-shaped supporting rack with a permeation sliding groove and an adjusting arm. The application method includes that the support is fixed on the drawing board by a self tapping screw; the supporting rack and the adjusting arm are connected by an adjusting screw and can spread to form support; when the connection between the supporting rack and the adjusting arm is adjusted to a required angle, the adjusting screw is closely screwed to fix the inclined angle of the drawing board. The support of the invention can be separately used at one side of the drawing board and two supports can also be used at both sides of the drawing board at the same time. A nylon snap can be pierced on the permeation groove at the tail end of the supporting rack and used as a handhold when the support is folded. When two supports are used simultaneously, the two supports can be connected by the nylon snap in the middle of which a rubber band can provide the tensile force to strengthen the stability of the drawing board and the supports. The portable and foldable drawing board support of the invention has simple structure, convenient use and light weight and is easy to carry; while being additionally installed on a common drawing board in the market, the support can be directly placed on a desk or other planes to be adjusted for use; furthermore, the support also requires low cost and is beneficial to being popularized.
Description
Technical field
The present invention relates to a kind of drawing board bracket and using method, refer to a kind of portable foldable drawing board bracket and using method thereof especially.
Background technology
Common drawing board is wooden tabula rasa, does not have any support, draws and can't conveniently regulate support angle when writing, and easily causes the cervical vertebra fatigue during horizontal use, and proposes, takes inconvenience.For overcoming above-mentioned drawback, the user need be placed on drawing board on the easel of adjustable-angle and use.Floor space was big when the common easel in market used, otherwise crank, in narrow space, can't use as middle and primary schools classroom, examination hall etc. or limited greatly; Structure is complicated, and volume is bigger, stores, carries inconvenience; The purchase maintenance cost is higher.
Summary of the invention
The present invention is for avoiding the existing weak point of above-mentioned technology, a kind of portable foldable drawing board bracket and using method thereof are provided, simple in structure, light and handy portable, easy to use, additional being installed in makes it can directly be placed on desk or other plane adjusted uses on the common drawing board in market, and with low cost, be beneficial to penetration and promotion.
The technical scheme of technical solution problem of the present invention is:
A kind of portable foldable drawing board bracket is characterized in that bracing frame 1 by vertical part and horizontal part form right angle " L " shape, and the vertical part of bracing frame 1 has a penetrating sliding tray 3, and the tail end of horizontal component has a penetrating groove 4.Bracing frame 1 and regulating arm 2 are cemented in the two ends up and down of a side of drawing board respectively by self-tapping screw 6,7.Bracing frame 1 is connect and is opened by set screw 5 by penetrating sliding tray 3 with regulating arm 2 and forms support, screws the just fixing angle of drawing board inclination of set screw 5 when being adjusted to required angle.
Feature of the present invention is that also this support can one-sided independent use, also can use both sides simultaneously by two supports.Can put on velcro 8 at the penetrating groove 4 of the tail end of bracing frame 1 horizontal component.When using two supports simultaneously, can connect two supports by velcro 8, the elastic 9 in the middle of the velcro 8 provides tension force, and two supports is stable when opening with assurance.
Feature of the present invention is that also velcro 8 can make handle and use when support draws in.
Feature of the present invention is that also two supports that use simultaneously both sides can regulate the angle of inclination respectively, to adapt to the out-of-flatness that the bottom surface may exist.
After manufacturing of the present invention and the installation, requirement detects qualified and works well.

The specific embodiment
Below pass through the specific embodiment, and in conjunction with the accompanying drawings the present invention be further described:
Use figure (rounding state) referring to Fig. 1 the present invention:
Velcro 8 can be used as handle and uses by penetrating groove 4.Use two supports simultaneously as left and right sides, then velcro 8 also can be used as handle and uses respectively by the penetrating groove 4 of two supports.
Use figure (open mode) referring to Fig. 2 the present invention:
Regulating arm 2 is cemented in the lower end of drawing board upper support frame place one side by self-tapping screw 7.Bracing frame 1 can be done 360 rotations of spending with regulating arm 2.Bracing frame 1 is connect by set screw 5 by penetrating sliding tray 3 with regulating arm 2.
Use two supports simultaneously as left and right sides, then by the penetrating groove 4 of two supports, the elastic 9 on the velcro 8 can provide suitable tension force to velcro 8 respectively, guarantees that two bracing frames connect for whole, and structure is more reliable and more stable.
Referring to Fig. 3 structure vertical view of the present invention, Fig. 8 structure upward view of the present invention:
The length of bracing frame 1 horizontal component is less than 1/2 of drawing board base length.The thickness of bracing frame 1 and regulating arm 2 can adjust according to the physical strength of manufactured materials.
Referring to Fig. 4 structure left view of the present invention, Fig. 6 structure right view of the present invention:
The length relation of bracing frame 1 penetrating sliding tray 3 makes support and drawing board have stability to the open angle of bracing frame.
Referring to Fig. 5 structural front view of the present invention, Fig. 7 structure dorsal view of the present invention:
Referring to Fig. 9 velcro structure of the present invention front view, Figure 11 velcro structure dorsal view:
Velcro 8 two ends are chemical fibre braid over braid 10, and positive and negative is firmly sewed on the hook face 11 and the matte 12 of velcro respectively.
Referring to Figure 10 velcro structure side of the present invention view:
Velcro 8 two ends chemical fibre braid over braids 10 need double-layer sewing, are beneficial to raising intensity.The length of matte 12 is greater than hook face 11, to guarantee to have suitable adjustable range.
