Abstract

The utility model discloses a stable high-strength electronic white board which comprises a surface plate, an upper adhesive layer, a substrate, a lower adhesive layer and a back plate from top to bottom. Upper reinforcing ribs extend downwards on the bottom surface of the upper adhesive layer; the top surface of the substrate is provided with upper grooves in which the upper reinforcing ribs can be inserted in a matching way; lower reinforcing ribs extend upwards on the top surface of the lower adhesive layer; and the bottom surface of the substrate is provided with lower grooves in which the lower reinforcing ribs can be inserted in a matching way. Compared with the prior art, the stable high-strength electronic white board has less layers, high integral strength, high evenness, high bending and deforming resisting capacity and high stability, the material cost of the stable high-strength electronic white board is greatly reduced, the production process is simplified, and the layers are bonded strongly and are not easy to separate.

Description

A kind of stable high strength electronics blank

Technical field

The utility model relates to a kind of interactive electric whiteboard, especially a kind of stable high strength electronics blank.

Background technology

Present stage; Common electronic whiteboard is layer structure; Concrete structure is for comprise panel, adhesive layer, nonwoven, substrate, adhesive layer, cystosepiment, backboard from top to bottom successively, and the electronic whiteboard number of plies of this kind structure is more, and process comparatively complicacy and material cost is higher; And poor adhesion between layer and the layer, flatness and counter-bending deformation ability are relatively poor relatively.

The utility model content

To the deficiency of prior art, the purpose of the utility model is intended to provide a kind of stable high strength electronics blank, and its number of plies is less relatively, saves material cost and convenient processing, is difficult for layering simultaneously, counter-bending deformability is stronger.

For realizing above-mentioned purpose, the utility model adopts following technical scheme:

A kind of stable high strength electronics blank; Comprise panel, last tack coat, substrate, following tack coat, backboard from top to bottom successively; The said lower surface of going up tack coat is to the last reinforcement that extends below; The upper surface of substrate has can keep supplying the upper groove that the reinforcement coupling is inserted, and the said upper surface of tack coat has down extended upward down reinforcement, and the lower surface of substrate has the low groove that can supply down the reinforcement coupling to insert.

The upper surface of said substrate and lower surface are respectively arranged with a plurality of upper grooves and the low groove that is arranged side by side; The lower surface of last tack coat is extended with a plurality of downwards and upper groove is gone up reinforcement one to one, and the upper surface of following tack coat has extended upward a plurality of and low groove descends reinforcement one to one.

Said substrate is an XPS.

The beneficial effect of the utility model is:

Than prior art, the electronic whiteboard number of plies of the utility model is less, has reduced material cost greatly, has simplified production technology; Simultaneously; Adhesion between its layer and the layer is stronger, not easily separated, and bulk strength is high; Have higher flatness and counter-bending deformability, and have advantages of higher stability.

Description of drawings

Fig. 1 is the structural representation of a kind of stable high strength electronics blank of the utility model.

The specific embodiment

Below, in conjunction with the accompanying drawing and the specific embodiment, the utility model done further describing:

As shown in Figure 1, be a kind of stable high strength electronics blank of the utility model, it is followed successively by panel 1, last tack coat 2, substrate 3, following tack coat 4, backboard 5 from top to bottom; Last tack coat 2 is used for glue panel 1 and substrate 3; Following tack coat 4 then is used for bonding backboard 5 and substrate 3, is respectively arranged with upper groove 31 and low groove 32 at the upper surface and the lower surface of substrate 3, and the lower surface of last tack coat 2 is extended with reinforcement 21 downwards; The form fit of the shape of this reinforcement 21 and upper groove 31; And be inserted in the upper groove 31, same, the upper surface of following tack coat 4 has extended upward reinforcement 41; This reinforcement 41 and low groove 32 form fit, and be inserted in the low groove 32.

The above-mentioned reinforcement 21 of going up cooperates with upper groove 31; On the one hand, increased the contact area of last tack coat 2 and substrate 3, increased the bonding force of substrate 3 with last tack coat 2; On the other hand; Last reinforcement 21 can play corrective action to the flatness of substrate 3, simultaneously, also can strengthen the counter-bending deformability of whole electronic whiteboard; In like manner, following reinforcement 41 cooperates with low groove 32, also can play above-mentioned effect.

According to known technology general knowledge; Can be arranged side by side a plurality of upper grooves 31 and low groove 32 respectively at the upper surface and the lower surface of substrate 3; Corresponding; Be provided with at the lower surface of last tack coat 2 and a plurality ofly go up one to one reinforcement 21, be provided with at the upper surface of tack coat 4 down and a plurality ofly descend one to one reinforcement 41 with low groove 32 with upper groove 31.

The substrate of the utility model can be selected XPS for use, perhaps other highdensity sheet materials.

For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to the technical scheme and the design of above description.
