Description

Technical Field

[0001] The patent of this invention relates to the technical field of connecting buckles, specifically a straight injection hook buckle and its production process. Background Art

[0002] At present, many domestic car seat manufacturers are gradually abandoning the traditional process of installing seat covers by binding with iron wire, and instead adopting a large number of injection hooks and raised cloth adhesive installation processes. Injection hooks are favored and praised by major car seat manufacturers. However, the injection hooks used in car seats are usually fixed to the car seat foam by spray foaming. Since the hooks are mainly responsible for fixing the seat cover, they are prone to fall off and separate when subjected to a certain traction force, resulting in poor connectivity between the hooks and the seat foam.

[0025] The following will be combined with the drawings in the embodiments of the patent of the present invention to clearly and completely describe the technical solutions in the embodiments of the patent of the present invention. Obviously, the described embodiments are only part of the embodiments of the patent of the present invention, not all of them. Based on the embodiments in the patent of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the patent of the present invention.

One side of the protective layer 7 is provided with a plurality of openings corresponding to the hook body 6. The other side of the protective layer 7 is provided with a magnetic conductive layer 8 and a wear-resistant layer.

[0027] In the above scheme, the hook buckle can be divided into one or two parts. One of the parts is to firmly set the adhesive layer 3, the base plate 4 and the loop 1 together through the braided layer 2. At the same time, a connecting column 5 and a hook body 6 are provided on the base plate 4, and the braided layer 2 is connected to the protective layer 7 by means of the connecting column 5 and the hook body 6. The magnetic conductive layer 8 is provided on the protective layer 7, which can be adsorbed on the magnetic object. In addition, the loop 1 is provided on the braided layer 2, and the loop 1 can be used to adhere to the hooked object to achieve the connection between plastic and metal. The braided layer 2 and the adhesive layer 3 are arranged inside the overall structure, which can play a buffering role for the connected object, and a hook body 6 is provided on a connecting column 5. After entering the opening of the protective layer 7, the protective layer 7 is clamped by the hook body 6, which greatly increases the protection stability of the installation connection and effectively prevents the protective layer and the magnetic conductive layer from falling off.

[0028] The production steps include:

[0029] S1, determine the width of the knitted item, and then cast on the needle according to this width. Use the long-tail cast-on method, wrap the yarn around a needle, then insert the needle into the loop and pull the yarn out to form a new stitch. Repeat this process until the required number of stitches is reached. After the cast-on is completed, the loops on the needle are evenly distributed to two or three needles for circular knitting, thereby realizing the processing technology of the knitting layer and the loops;

[0030] S2, select hot melt glue, heat the glue in advance and place the glue in a heat preservation container, apply the melted hot melt glue on the surface of the braided layer, apply the glue evenly around one side of the braided layer, and draw a circle in the middle of the braided layer with glue;

[0031] S3, one side of the substrate material is quickly bonded to the braided layer through the above-mentioned glue, and the two are quickly attached together, and a certain pressure is applied to make the glue fully contact and solidify;

[0032] S4, placing part of the material into an injection molding machine, introducing the material into a mold through the injection molding machine, setting a hook-shaped groove and a columnar groove in the hollow position after the upper and lower molds are closed, extruding the material into a column with a hook, and fixing the flat end of the column to the substrate by hot melting;

[0033] S5, introducing another part of the material into another mold, wherein the mold clamping position in the other mold is set to be a protrusion with a hook shape, and after the material is molded, the surface of this part of the material is a template with a hook-shaped groove, and the groove end of the template can be combined with the hook-shaped protrusion on the substrate;

[0034] S6, mixing part of the synthetic material with magnetic metal powder and putting the mixture into a mixer to synthesize a magnetic material having plasticity;

[0035] S7, introducing the magnetic synthetic material into a flattening machine to process the material into a magnetic soft board, and combining it with the template of the protective layer through a thermal adhesive;

[0036] S8, finally, by evenly adding a sticky substance on a wear-resistant layer, the sticky side and the magnetic material of the protective layer are bonded to each other.

[0037] In the above steps, a loop of wool is provided on the braided layer by a weaving method, which is used to facilitate the mutual fitting and connection with the coil of any other device. At the same time, hot melt adhesive is provided in the middle and around the braided layer. When the braided layer is attached to the substrate, the hot melt adhesive is pressed between the substrate and the braided layer by squeezing the substrate and the braided layer. Compared with extrusion after uniform application, the gap between the two will be smaller, and the excess overflowing adhesive will be squeezed inward to prevent the adhesive from being outside the substrate and the braided layer. The hook surface and the hook groove are then extruded through a mold and attached to the base surface and the protective layer. At the same time, a panel with magnetic material is provided on the other side of the protective layer, which can be adsorbed on the magnetizable surface for fixed support. By directly combining the magnetic powder with the plastic material, the overall flexibility is increased. Compared with sticking magnetic strips on the panel, the integrity is more beautiful and will not break easily.

[0038] During the mixing process of magnetic materials, the interior of the mixer is made of non-magnetic materials.

[0039] It prevents the magnetic powder from being adsorbed inside the mixer during the mixing process, resulting in a decrease in magnetism, and will not affect the operation of the mixer.

[0040] During the process of flattening and forming magnetic materials, the surfaces that come into contact with the flattening machine and the material are all non-magnetic materials.

[0041] During the flattening process, the magnetic powder will not be concentrated upward or downward due to magnetic adsorption problems, and the magnetism will be more uniform.

[0042] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims, and any reference numerals in the claims should not be regarded as limiting the claims involved.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
