Detailed ways

As shown in Figures 1 and 2, the utility model is mainly composed of a fixing seat 10, a hollow fastener 20, and a fixing rod 30, which is a first plate 40 ( For example, between the side panels of the TV cabinet) and the second plate 50 (such as the top panel of the TV cabinet), the combined product does not need tool assistance in the process of assembling; wherein:

The aforementioned fixing seat 10 is buried in a fixing hole 41 of the first plate 40, the bottom is a junction 11 with anti-reverse function, and the top is provided with a buttonhole 12; the inner edge of the buttonhole 12 is further provided with a buttoning groove 13, and the inner diameter of the fastening groove 13 is larger than the inner diameter of the fastening hole 12.

The hollow fastener 20 is embedded in the through hole 51 on the second plate 50. The hollow fastener 20 includes a cap body 21 that can be embedded in the through hole 51, and a cap body 21 that is arranged below the cap body 21 and penetrates through the hole. The threading rod 22 of the hole 51 and a through hole 23 passing through the cap body 21 and the threading rod 22 from top to bottom. Wherein, the threading rod 22 can be inserted into the button hole 12 of the fixing seat 10, and its outer wall surface has a plurality of split grooves 24 and is provided with an elastic positioning part 25, and the cap body 21 of the hollow fastener 20 is embedded in the second plate 50. through hole 51 of the through hole 51, and when the rod 22 passes through the through hole 51 and is inserted into the button hole 12 of the fixing seat 10, the elastic positioning part 25 can be elastically buckled in the fastening groove 13, so that the first plate 40 and the second plate A temporarily fixed state is formed between the sheets 50 .

The fixed rod 30 includes a rod body 31 and a rod head 32. The rod body 32 can be inserted into the through hole 23 on the inner edge of the hollow fastener 20, and is pushed against the wall surface of the through hole 23 on the inner edge of the elastic positioning part 25, so that the elastic positioning The part 25 is maintained in the state of being buckled in the fastening groove 13, thereby allowing the hollow fastener 20 and the fixing seat 10 to be firmly combined; , the bonding of the first plate 40 and the second plate 50 can be completed.

As shown in Figures 3 and 4, with the above structure, when the user wants to join the first plate 40 and the second plate 50, the fixing seat 10 can be embedded in the fixing hole 41 of the first plate 40 first. , let the second plate 50 be superimposed on the first plate 40, and embed the cap 21 of the hollow fastener 20 into the through hole 51, so that the penetrating rod 22 passes through the through hole 51 and is inserted into the buckle of the fixing seat 10 In the hole 12 , the elastic positioning portion 25 is fastened to the fastening groove 13 , thereby forming a temporary fixation between the first plate 40 and the second plate 50 .

In the above assembly process, when the hollow fastener 20 passes through the through hole 51, and then penetrates the button hole 12 of the fixing seat 10 with the bottom piercing rod 22, since the outer edge wall of the piercing rod 22 is provided with a plurality of split grooves 24, it has Inwardly compressed space, so the elastic positioning portion 25 will be compressed inwardly when it is against the inner edge wall of the button hole 51, so that the elastic positioning portion 25 with a larger outer diameter can pass through the button hole 12 with a smaller outer diameter until The elastic positioning portion 25 is aligned with the fastening groove 13 and snapped elastically into the fastening groove 13 .

As shown in Figure 5 and Figure 6, after the hollow fastener 20 is fastened with the fixed seat 10, the rod body 32 of the fixed rod 30 is inserted into the through hole 23 of the hollow fastener 20, at this time, the rod body 32 of the fixed rod 30 is pressed against The wall surface of the through hole 23 on the inner side of the elastic positioning part 25 will make the elastic positioning part 25 close against the inner wall of the fastening groove 13 and cannot be compressed inwardly, and the outer diameter of the elastic positioning part 25 is larger than the inner diameter of the button hole 12. Therefore, The hollow fastener 20 is tightly fastened to the fixed seat 10 and cannot be pulled out upwards, so that the fixed seat 10, the hollow fastener 20, and the fixed rod 30 are tightly combined without falling off, so that the first plate 40 and the second plate The sheet 50 is joined quickly, and the combined product can be quickly assembled without tools.

As shown in Fig. 1, Fig. 2 and Fig. 7, when the above combined structure is to be disassembled if necessary, at least one guide portion 26 is additionally provided on the upper side of the through hole 23 of the aforementioned hollow fastener 20, and the fixed rod 30 The bottom of the rod head 32 is provided with a guide bump 33 relative to the guide portion 26, so when the fixed rod 30 rotates, the guide bump 33 can allow the fixed rod 30 to move upwards along the guidance of the guide portion 26, so that The rod body 32 of the fixing rod 30 breaks away from the position abutting against the wall surface of the through hole 23 inside the elastic positioning part 25, so that the hollow fastener 20 returns to the state in which the elastic positioning part 25 elastically buckles in the fastening groove 13 of the fixing seat 10; At this time, since the hollow fastener 20 and the fixed seat 10 are in an elastic buckle state, the hollow fastener 20 can be pulled upwards, and the elastic positioning part 25 is retracted and separated from the fixed seat 10, so that the first plate 40 and the fixed seat 10 can be separated. The second sheet 50 is separated.

In addition, in order to make the disassembly process smooth, a force application part 34 can be further provided on the rod head 32. When the combined product is disassembled, the force application part 34 can generate force for the lifting action of the fixed rod 30. Auxiliary function; in the icon, the force application part 34 is a tool hole for a screwdriver to apply force, and it can also be a square or hexagonal hole during implementation, for various tools to apply force.

In addition, the hollow fastener 20 can further be provided with at least one stopper 27 on the outer edge of the cap body 21. When the cap body 21 is embedded in the through hole 51 of the second plate 50, the stopper 27 can be connected with the through hole 51. The wall surfaces of the hollow fasteners cooperate with each other to increase the friction between the cap body 21 of the hollow fastener and the through hole 51 of the second plate 50 to prevent the hollow fastener 20 from deflecting when the fixing rod 30 is disassembled.

In addition, the joint portion 11 of the fixing seat 10 shown in FIG. After the seat 10 is plugged into the fixing hole 41 of the first plate 40 , a non-reverse function is formed between the joint portion 11 and the fixing hole 41 , so that the fixing seat 10 can be firmly combined in the first plate 40 .

In addition, when the joint part 11 is implemented, as shown in Figure 8, the external thread structure can be used to screw on the predetermined internal thread of the fixing hole, which is mainly used when the first plate and the fixing hole are made of metal. Because the hardness of the metal material is relatively high, the fixing seat 10 can be more firmly fixed in the fixing hole of the first plate by means of screw teeth, which is especially suitable for shelves, tables, chairs, etc. made of metal materials. and other combined products.

However, the above description is only a preferred embodiment of the present utility model, and does not limit the patent scope of the present utility model, so any simple modifications and equivalent structural changes made by using the description of the utility model and the contents of the accompanying drawings, All should be included in the patent scope of the utility model in the same way.
