Description

Technical Field

[0001] The utility model relates to the technical field of plastic structures, in particular to a nut-mounted plastic structure. Background Art

[0002] Plastic products require nuts to be embedded in the post-process, and there are many existing ways to embed nuts. One of them is to hot-melt the nut embedding structure again after the plastic product is formed, but this structure is time-consuming and there is a risk of glue overflow after hot melting. The second is to cold-press the nut embedding structure again after the plastic is formed, but in this case, there is a risk that the nut will easily fall off. If the nuts are embedded in the above way during the actual production process, it will not only be time-consuming and labor-intensive, but also increase costs. Utility Model Content

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0029] like Figure 1-Figure 5 As shown, in one embodiment, a nut 3 is installed in a plastic structure, and the entire nut 3 is installed in the structure of a plastic product and is composed of multiple structural assemblies, including a fixing fixture 1 for fixing and placing a product workpiece 2 to be processed, that is, a plastic product, in which a nut 3 is inserted, and an air suction fixture 4 is arranged at the upper end of the product workpiece 2. The air suction fixture 4 and the nut 3 are pre-assembled into one body before being inserted into the plastic product, and the air suction fixture 4 and the nut 3 are connected in a manner that the air suction hole 5 opened on the air suction fixture 4 is adsorbed on the nut 3, which can effectively prevent the air suction fixture 4 from falling off from the nut 3. A guide pin 7 is also included, which passes through the air suction fixture 4 and is inserted into the inside of the nut 3.

[0030] A groove 8 is provided on the outer surface of the bottom circumference of the nut 3, and a plurality of buckles 9 are provided on the bottom of the product workpiece 2. The buckles 9 can be inserted into the groove 8, which can effectively improve the stability of the connection between the nut 3 and the plastic product and prevent the nut 3 from falling off the plastic product.

[0031] Through the above technical solution, the nut 3 can be quickly assembled into the plastic product through the suction jig 4. At the same time, a buckle 9 structure is provided at the connection position between the nut 3 and the plastic product to engage with each other, which can improve the stability of the plastic product after connection, while improving the assembly efficiency and the product yield.

[0032] Furthermore, a plurality of reinforcing ribs 10 are arranged inside the product workpiece 2, and the reinforcing ribs 10 are arranged at intervals between two adjacent buckles 9, which can effectively improve the connection strength between the product workpiece 2 and the nut 3 during assembly, thereby ensuring the strength of the connection between the two and preventing the plastic product from breaking during the assembly of the nut 3.

[0033] Further, the guide needle 7 is described as a cylindrical structure with a pointed end at one end, which can be inserted into the through holes in the suction jig 4 and the nut 3, so as to assemble the suction jig 4 and the nut 3 as one. Specifically, the length of the guide needle 7 is not greater than the sum of the lengths of the suction jig 4 and the nut 3, and its outer diameter is adapted to the through holes of the suction jig 4 and the nut 3.
