Detailed Description

The following describes the present invention with reference to the accompanying drawings.

It is easily understood that, according to the technical solution of the present invention, a plurality of structural modes and implementation modes that can be mutually replaced by those of ordinary skill in the art can be achieved without changing the spirit of the present invention. Therefore, the following detailed description and the accompanying drawings are only exemplary illustrations of the technical solutions of the present invention, and should not be construed as limiting or restricting the technical solutions of the present invention in its entirety or as a limitation of the present invention.

The terms of orientation of up, down, left, right, front, back, top, bottom, and the like referred to or may be referred to in this specification are defined relative to the configuration shown in the drawings, and are relative terms, and thus may be changed correspondingly according to the position and the use state of the device. Therefore, these and other directional terms should not be construed as limiting terms.

The glue joint assembly in this embodiment, as shown in fig. 1-3, includes a glue groove 01 for injecting a sealant, which is disposed on the first plate 001, and an insert plate 02, which is disposed on the second plate 002, wherein the insert plate 02 is inserted into the glue groove 01, and the insert plate 02 protrudes from the surface of the second plate 002;

the glue groove 01 comprises a groove bottom 11, a limiting side 12 and a glue overflowing side 13, wherein the limiting side 12 and the glue overflowing side 13 are arranged on two sides of the groove bottom 11, the upper end of the limiting side 12 is tightly attached to the surface of the second plate 002, a glue overflowing gap 131 is reserved between the upper end of the glue overflowing side 13 and the surface of the second plate 002, and the glue overflowing side 13 is located on the inner side of the limiting side 12.

Specifically, be provided with gluey groove 01 at the edge of first board 001, the edge correspondence of second board 002 has set up picture peg 02, pour into sealed glue back in gluey groove 01 during the installation, insert picture peg 02 in gluey groove 01, sealed glue in gluey groove 01 receives the extrusion and can spill over to both sides, because spacing side 12 is different with the height of overflowing gluey side 13, sealed glue can only pour the height of overflowing gluey side 13 at most, consequently, the sealed glue that spills over from spacing side can be sheltered from the root at spacing side and picture peg 02 by spacing side 12, almost can not spill over outside gluey groove 01, and sealed glue relatively poor mobility, sealed glue most all can spill over gluey side 13 to overflowing.

In this embodiment, the limiting side 12 of the glue groove 01 is located outside the glue overflow side 13, most of the sealant flows to the inner side, and does not overflow the edges of the first plate 001 and the second plate 002, so that only a small glue overflow area x needs to be reserved outside the limiting side 12, the glue joint black edge of the first plate 001 and the second plate 002 is narrow, and the influence degree on the appearance is small.

Further, the width of the glue groove 01 is gradually increased along the direction from the groove bottom 11 to the groove opening; in the process of inserting the inserting plate 02, the sealant is guided to a certain extent, the sealant can quickly overflow to the glue overflow side 13, and the bonding strength of the root part of the inserting plate 02 is increased.

Specifically, the limiting side 12 and the glue overflowing side 13 are inclined towards two sides, namely, the included angles between the limiting side 12 and the glue overflowing side 13 and the groove bottom 11 are obtuse angles, and the preferred angle is 95-98 degrees; the limiting side 12 and the glue overflowing side 13 have certain inclination, and if the inclination is too large, the groove opening of the glue groove 01 is too large, so that the glue joint black edge is too wide.

Furthermore, the sealant adopts two-component glue, the viscosity of the two-component glue is high, the fluidity is poor, the two-component glue cannot flow and overflow quickly in the process that the inserting plate 02 is inserted into the glue groove 01, and the sealant is suitable for glue joint components with small width of the glue groove 01.

Further, the insertion plate 02 includes a connection end 21 and an insertion end 22, the connection end 21 connects the second plate 002 to the insertion end 22, and the connection end 21 has a thickness smaller than that of the insertion end 22. Because the glue joint is generally made of injection molding materials, the connection width between the inserting plate 02 and the second plate 002 is reduced, the appearance shrinkage degree of the upper surface of the second plate 002 can be reduced, and the appearance quality of the second plate 002 is improved; in addition, the thickness of the connecting end 21 is smaller than that of the inserting end 22, so that the contact area between the connecting part of the second plate 002 and the inserting plate 02 and the sealant can be increased, and the connecting strength is enhanced.

Specifically, one side of the connecting end 21 close to the glue overflowing side 13 is flush with the insertion end 22, and one side of the connecting end 21 close to the limiting side 12 and the insertion end 22 form a step surface; when the inserting plate 02 is inserted into the glue groove 01, the sealant extruded to one side of the limiting side 12 flows along the limiting side 12 to the direction of the notch, flows into the step surface between the inserting end 22 and the connecting end 21, and is filled at one side of the inserting end 22; the sealant pressed toward the overflow side 13 overflows into the overflow gap 131 under the guidance of the overflow side 13 and the connecting surface where the connecting end 21 and the inserting end 22 are flush with each other.

Further, as shown in fig. 4, the glue groove 01 is internally provided with limiting convex points 03 at intervals for limiting the inserting plate 02, and the limiting convex points 03 are supported at the lower ends of the two sides of the inserting plate 02 and are in contact with the inserting end 22 of the inserting plate 02 to limit the inserting plate 02 and enhance the connection strength.

Specifically, the limit bumps 03 are staggered in the glue groove 01, and two adjacent limit bumps 03 are respectively connected with the limit side 12 and the glue overflow side 13 and are positioned on the inserting plate 02 and connected with the limit side 12 or the glue overflow side 13; the limiting convex points 03 are connected with the limiting side 12 and the glue overflowing side 13 in a staggered mode, are respectively in contact with two side walls of the inserting plate 02, limit the inserting plate 02 from two sides and enable supporting force to be balanced.

Referring to fig. 3, with the glue joint assembly in this embodiment, the width a of the connecting end 21 of the board 02 can be reduced to 1.0-1.5mm, the height b is set to 1.5mm, the width c of the step surface between the connecting end 21 and the insertion end 22 is 1.2-1.5mm, and the length d of the glue joint black edge can be reduced to 4.5mm, which is the smallest black edge in the industry at present.

What has been described above is merely the principles and preferred embodiments of the present invention. It should be noted that, for those skilled in the art, on the basis of the principle of the present invention, several other modifications can be made, and the protection scope of the present invention should be considered.
