SOLUTION: A retractable plate material assembling unit includes a fastening female portion and a rotating fastening male portion, and the rotating fastening male portion includes a rotating fastening male portion base 2 provided with a fastening male portion base hole 5 and a fastening male portion base hole. It is provided with a rotating fastening male element 4 arranged inside, and has an assembly hole in the fastening female portion that matches the fastening male element head 7 which is the front end of the rotating fastening male element, and is provided with a rotating fastening male element base. A male element head hole for fastening that communicates with the male element for fastening is provided on the side surface of the male element, and a lead-in groove that communicates with the male base hole for fastening is provided on the male part for rotational fastening, so that the male element for rotational fastening is retracted. In this state, the pulling portion of the rotating fastening male element is pulled into the pull-in groove. [Selection diagram] Fig. 1

Description

  The present invention relates to the technical field of assembly accessories for plate products, and mainly relates to a fastening member structure applied to furniture assembly.

  The basic accessories of conventional furniture include a top plate, a bottom plate, side plates on both sides, a back plate on the back, legs, etc., and such furniture generally has screw bolts except that the drawer is placed inside. It is fixed by conventional means such as nails or gluing.

Such products are already assembled at the time of shipment from the factory or assembled at the sales floor. The consumer purchases the finished product that has been assembled, and the entire product is transported during transportation.
In other words, in the current production and sales of furniture, desks and shelves are basically handled in units of finished products, so transportation costs are high, inconvenient, spend a lot of labor, and transport the upper and lower floors. Difficult problems occur. Especially when moving, these tendencies are strong, and if damaged, it is difficult to repair, and usually the whole is discarded.

In order to solve such problems, various fastening members that are easy to assemble have appeared on the market, and when two plates are assembled vertically, a rotating fastening member, a sliding fastening member, and an end face fastening Assembly members such as members are used.
However, in these assembly members, the male part of the fastening member protrudes on the surface of the plate material, and the male part of the fastening member breaks during transportation and unloading and damages the surface of the furniture plate material. In addition to packaging, it has become a way for buyers to assemble it themselves.

When using a rotary fastening member, the assembly head (fastening male element head) protrudes, so it can be used only when the assembly space is not limited, and the end surface fastening member can be used even when there is a spatial limitation of assembly Yes, but only on the top or bottom edge of the material being assembled.
If the article is large, it affects the bonding performance, and if it is the upper end of the article to be assembled, the part is exposed on the end face, which affects the aesthetic appearance. Since the slide-type fastening member and the end-face fastening member are slide-type couplings, there is a problem in safety, such as lack of force in the third direction, preventing sliding in the opposite direction effectively, and coming loose. is there.

  Each assembly fastening member described above has the following problems in any design. As for the assembly order, if the purchaser does not understand the product well or is not careful, it will be noticed that it will not be assembled at a certain stage, and it will be necessary to disassemble some or all of the assembled parts, thereby wasting time. It is a point which spends or damages the board material of furniture.

  In the present invention, the assembly order of the material structure is not limited at the time of assembly, and the assembly is easily completed by simply arranging the plate material of each part and pushing the fastening male element head from the plate material and joining it with the fastening female part. An improved rotary fastening member having a robust mounting structure, convenient for use and not restricted for use.

In order to solve the above-mentioned technical problem, the technology employed in the improved rotary fastening member proposed by the present invention is as follows.
The rotation fastening member of the present invention includes a fastening female portion and a rotation fastening male portion that are respectively fixed on both plate materials to be assembled and fastened together to fix the plate materials together. The rotation fastening male part includes a rotation fastening male part base and a rotation fastening male element, a fastening male part base hole is provided in the rotation fastening male part base, and the rotation fastening male element is located in the fastening male part base hole. The front end of the rotating fastening male element is a fastening male element head. The fastening female part has an assembly hole matching the fastening male element head, and the fastening male element head is inserted into the assembly hole to fix the fastening female part and the rotational fastening male part together.

  A fastening male element head hole is provided on a side surface of the rotating fastening male part base, the fastening male element head hole and the fastening male part base hole communicate with each other, and the fastening male element head is a fastening male element head hole. The retraction groove is connected to the fastening female part, and a retraction groove is further provided on the rotation fastening male part base. The retraction groove and the fastening male part base hole communicate with each other, and the rotation fastening male element is drawn. When this occurs, the pulling portion of the rotating fastening male element is drawn into the pulling groove, and the fastening male element head fits in the fastening male element head hole.

  A packing tooth portion is provided on the outer surface of the fastening female portion.

  The outer surface of the fastening female part is further provided with at least one positioning convex part protruding outward.

  According to the present invention, the fastening male element head is retracted into the fastening male element head hole due to the design of the pull-in groove, so that the use space is not limited, and it is loosened by the acting force from three different directions after assembly. It can be strengthened by using it in combination with other parts. In addition, it can be used alone for furniture assembly members that receive a small force and volume, and can be used in combination with a sliding fastening member, an end surface fastening member, or other components for assembling a cabinet that receives a large force.

The structure figure of the rotation fastening male part of this invention. The structure figure of the rotation fastening male part base of this invention. The structure figure of the fastening female part of this invention. The structure figure of the use condition of this invention.
