Therefore, the new connecting piece is designed to realize the manufacture of the outer frame of the carved sofa, the root carving work, the artwork with large complex special-shaped structure and the like, and the specific structure and the description are as follows:
in this embodiment, the engraved product is first decomposed into a unit structure of one segment, each segment is obtained by blow molding, as shown in fig. 1, which is an engraved blow molding segment a to be connected, as shown in fig. 2, which is another engraved blow molding segment B to be connected, and then the segments a and B need to be connected, where of course, a in fig. 1 and B in fig. 2 are simplified drawing methods, and in fig. 1 and 2, the copy shape, grain, pattern, etc. of the exterior of the engraved blow molding are not drawn, but the understanding of the structure and principle of the connecting piece of this embodiment is not affected. As shown in fig. 1, at least one prefabricated groove 1 is arranged on the connecting end surface of the carving type blow molding product segment a, a protrusion 2 corresponding to the prefabricated groove 1 is arranged on the carving type blow molding product segment B, the size and shape of the prefabricated groove 1 are matched with those of the protrusion 2, the depth of the prefabricated groove 1 is larger than that of the protrusion 2, a first diversion structure is arranged at the bottom of the prefabricated groove 1, a second diversion structure is arranged on the protrusion 2, and quick-drying glue 9 is placed in the prefabricated groove 1.
Specifically, as shown in fig. 3 and 4, the first diversion structure is an expansion groove 11, the expansion groove 11 is communicated with the prefabricated groove 1, the length of the expansion groove 11 is larger than that of the prefabricated groove 1, the second diversion structure is a conjoined groove 12 with a large inner side and a small outer side, and one smaller end of the conjoined groove 12 is positioned at the end face of the protrusion 2, preferably, the expansion groove 11 and the prefabricated groove 1 of the embodiment can form a T-shaped groove, of course, the expansion groove 11 can also be any other groove, as long as the length of the expansion groove 11 is ensured to be larger than that of the prefabricated groove 1, the expansion groove 11 and the prefabricated groove 1 form a conjoined groove with a large inner side and a small outer side, when the engraving type blow molding product A, B starts to be connected in a relative movement, the protrusion 2 on the engraving type blow molding product section B is gradually inserted into the prefabricated groove 1 on the engraving type blow molding product section a, the bulge 2 extrudes the quick-drying adhesive 9 in the prefabricated groove 1, the quick-drying adhesive 9 subjected to extrusion enters the expansion groove 11 and the conjoined groove 12, after the engraved blow molding product section A, B is completely jointed, the expansion groove 11, the prefabricated groove 1 and the conjoined groove 12 form a cavity similar to an H shape, the two ends of the cavity are large and the middle is small, namely the expansion groove 11 and the bottom end of the conjoined groove 12 are large, the prefabricated groove 1 at the contact position of the engraved blow molding product section A, B is small, the quick-drying adhesive 9 forms a back-off similar to the H shape along the cavity similar to the H shape, meanwhile, the bulge 2 well realizes adhesion with the prefabricated groove 1 through the quick-drying adhesive 9, as shown in figure 5, the quick-drying adhesive 94 in the expansion groove is the quick-drying adhesive of the engraved blow molding product section A, and 95 is the quick-drying adhesive of the conjoined groove, namely, the quick-drying adhesive flowing into the conjoined groove 12 on the carving type blow molding product segment B forms a firm H-shaped fastener after the quick-drying adhesive is hardened, and the carving type blow molding product segment A, B is firmly adhered and buckled, so that the carving type blow molding product segment A, B cannot be separated, and the carving type blow molding product segment A, B cannot be loosened, is firmly connected and has very high tightness. Similarly, the joining of all engraved blow mold segments may be accomplished.
It can be understood that the quick-drying glue of this embodiment is generally called as a glue which is in a viscous state or semi-solid semi-liquid state just at first and has adhesion, and then can be solidified and hardened in a short time, the quick-drying glue of this embodiment is preferably a marble glue or an AB glue, the marble glue is made of two raw materials, namely, an epoxy resin and an unsaturated resin, the marble glue made of the unsaturated resin can be solidified in a moist environment, the effect is also good, in addition, the excellent performance of the marble glue is mainly reflected in the aspects of hardness, toughness, rapid solidification, polishing, weather resistance, corrosion resistance and the like, and the proportion of the glue and the solidifying agent is 100:2-4, the comprehensive performance is best; the AB glue can automatically adjust the mixing proportion according to the requirement.
It can be understood that the pre-fabricated groove 1 in this embodiment may be a square groove, a spherical groove, or a groove with other shapes, and the shape of the protrusion 2 may be a square protrusion, a spherical protrusion, or another protrusion matching or fitting with the shape of the pre-fabricated groove 1; the expansion groove 11 can be a groove with any structure such as a square groove, a spherical groove and the like, and is larger than the square groove 1, so that a conjoined groove with large inner part and small outer part can be formed, and the quick-drying adhesive 9 can form a back-off; the conjoined groove 12 can meet the requirement of the inner size and the outer size, so that the quick-drying adhesive 9 forms two symmetrical back-off on the engraving type blow molding product segment A, B. Fig. 22 shows a connection structure of a pregroove 1 with a spherical groove structure and a spherical protrusion 2.
As shown in fig. 6 and 7, which are relatively complex-structured engraved blow molding segments, it can be seen from the figures that the contact surfaces of the two engraved blow molding segments are not a single plane, but are a plurality of contact surfaces which are not on the same plane, and the conventional clamping manner cannot be realized at all, because the two segments cannot be fastened by the fastener in a manner of transverse or longitudinal relative movement, the connection manner of the engraved blow molding segments A, B can be utilized to align and squeeze the contact surfaces to be connected simultaneously, so that the quick-drying adhesive 9 in the prefabricated groove 1 forms a reverse buckle to attach the two contact surfaces, and simultaneously adhere the protrusions 2 and the prefabricated groove 1, thereby realizing the tight and reliable connection of the contact surfaces of the segments. In this embodiment, the connecting structure such as a general external connecting piece or a fastener cannot realize connection at all, even though the connection can not influence the shape of the connecting structure, for example, the connecting structure is manufactured by carrying out sectional blow molding on the fabulous wild beast artwork in a blow molding mode, such as a section a, b, c, d, e, f, g of an engraving blow molded product, etc., wherein the structure of a section c is shown in fig. 24, the structure of a section e is shown in fig. 25, the connecting assembly of the embodiment is prefabricated on each section, namely, each section is formed on the blow molded product during blow molding, then the connecting assembly of the embodiment is adopted to connect the sections c and e one by one, the hidden connection can be realized in the whole process, any connecting part is not exposed, and the shape, the texture and the integrity of the pattern of the Pixiu engraving product are greatly maintained. Likewise, for the root carving and engraving sofa outer frame, the connecting and manufacturing can be performed in the mode, so that the volume and the production cost of manufacturing equipment are greatly reduced.
According to the embodiment, through the connecting structure formed by the prefabricated groove 1, the expansion groove 11, the bulge 2, the conjoined groove 12 and the quick-drying adhesive 9, the instant forming of the back-off can be completed only through alignment and extrusion in the connecting process, the instant connection is realized without preparing a fastener in advance, the production requirement is reduced, various connection can be met without considering the size problem of the fastener, and the production of blow-molded products, especially engraving type blow-molded products, such as engraving type sofa outer frames, root engraving works, artistic works of large complex special-shaped structures and the like, is easy, the production cost is low, and the obtained engraving type blow-molded products are high in firmness and are not easy to loose. In addition, the connecting piece is essentially different from the traditional hot melting mode in the connecting process, and no heating mode is needed in the connecting process, so that the prefabricated groove, the expansion groove, the T-shaped groove and the like on the carving type blow molding product segment are prevented from deforming, and the connecting reliability is ensured.
