 <First Embodiment>

 As shown in FIG. 2A to FIG. 2A, a fastener group structure is used for connecting a first plate body 21 and a second plate body 22. The fastener assembly structure includes a latch 24 and a screw member 23. The screw member 23 includes a screw head 231, a screw rod 232 and a spacer 233. The screw 232 is inserted into the first plate body 21 to be connected to the first plate body 21. The screw head 231 is spaced apart from the first plate body 21. The spacer 233 can abut against the upper surface 211 of the first board body 21 to generate a frictional force in a horizontal direction relative to the first board body 21, thereby increasing the mechanical strength of the joint. In addition, the spacer 233 can also control the depth of the screw member 23 to drill down into the first plate body 21, so that the screw member 23 stops at a specific drilling depth; that is, the spacer block 233 is on the screw rod. The position on the 232 determines the height Η between the screw head 231 and the upper surface 211. Therefore, the drilling depth of the screw member 23 can be controlled by the arrangement of the spacer 233. As a result, since the screwing depth of the screw member 23 is fixed, even if the screw shaft 232 is pointed at the lowermost portion, there is no need to worry that the screw member 23 is too deep. In the present embodiment, the lower half of the screw shaft 232 can be locked or screwed into the first plate body 21 by rotation. In addition, the spacer 233 may be disposed above the upper surface 211 or may be buried under the upper surface 211 (as shown in FIG. 2A). The spacer 233 is buried under the upper surface to save space. .

The second plate body 22 is provided with a groove 223 at the lower side for receiving the pin 24. The left side of the latch 24 includes a body 241 and a forked member 242 on the right side. The body 241 is fixed to the groove bottom surface 2231 in the groove 223 by three fixing members 2411, so that the pin 24 is firmly coupled to the lower side of the second plate body 22. The fork-shaped member 242 is spaced apart from the groove bottom surface 2231 of the second plate body 22. The latch 24 includes a receiving slot 244 that is located at the portion 242A of the fork member 242.

 As shown in FIG. 2A and FIG. 2B, when the screw member 23 and the first plate body 21 are moved to the left, the screw rod 232 can enter the opening 243 between the two branch portions 242C of the fork member 242. The two branch portions 242C of the fork member 242 can be inserted under the screw head 231. Thereby, the fork member 242 can be simply and quickly joined or separated from the screw member 23. After the fork member 242 and the screw member 23 are coupled to each other, the screw head 231 is clamped by the fork member 242 and the groove bottom surface 2231, and the fork member 242 is screwed by the screw head 231 and the first The upper surface 211 of the plate body 21 is clamped. Therefore, the second plate body 22, the screw head 231, the fork element 242 and the first plate body 21 can be arranged in order from top to bottom and abut. Further, after the fork member 242 and the screw member 23 are coupled to each other, the upper portion of the screw head 231 is connected to the groove bottom surface 2231 of the second plate body 22, and the fork member 242 is disposed below. At the same time, the upper surface of the fork element 242 is connected to the screw head 231, and the upper surface of the first plate body 21 is abutted. Therefore, the screw head 231 simultaneously applies a frictional force to the fork member 242 and the second plate body 22, and the fork member 242 simultaneously applies a frictional force to the screw head 231 and the first plate body 21. Therefore, the friction between the first plate 21, the screw head 231, the fork member 242 and the second plate 22 can be maximized to increase the engagement of the fork member 242 with the screw member 23. The mechanical strength makes the bond more stable. Further, when the screw member 23 is moved to the left, the screw head 231 is located on the branch portion 242C, and the screw head 231 can be spliced or not in the accommodating groove 244. As shown in FIG. 2B, the turret of the accommodating groove 244 is the same as the turret of the screw head 231, so that the screw head 231 can abut against the accommodating groove 244 in a fully fitted state. That is, when the screw member 23 is inserted to the leftmost side, the receiving groove 244 can receive and contact the screw head 231, thereby the friction between the receiving groove 244 and the screw head 231 or Combined with the mechanical strength, it can be further increased. Further, in the present embodiment, the two branch portions 242C of the fork-shaped member 242 are structures extending rightward from the root portion 242A.

In the present embodiment, the screw shaft 232 is provided with a threaded structure, and the screw shaft 232 has a blunt structure at the bottom. Therefore, before the screw member 23 is drilled into the first plate body 21, a hole for accommodating the screw rod 232 must be pre-drilled. Moreover, the final position of the screw head 231 (i.e., the relative height difference between the screw head 231 and the first plate body 21) is determined by the depth of the pre-drilled hole.

 When the latch 24 and the second plate 22 are moved to the rightmost position, the screw head 231 can abut or not abut against the root 242A of the fork member 242. When the screw head 231 abuts the trunk portion 242A of the fork member 242, the screw head 231 can also simultaneously contact the groove bottom surface 2231 and the fork member 242. As a result, the screw head 231 is biased above, below, and to the left, so that the mechanical strength of the combination is greater.

 <Third embodiment>

 In the foregoing embodiment, the groove 223 for receiving the plug 24 is disposed on the lower side of the second plate 22; however, as shown in FIG. 4, the groove 223 may also be disposed on the first plate. The upper side of the 21 is for receiving the screw member 23. That is, the screw rod 232 is fixed to the groove bottom surface 2231 of the first plate body 21, and the pin 24 is firmly fixed to the lower side of the second plate body 22. When the second plate 22 and the latch 24 are moved downward to the right, the fork member 242 and the screw member 23 can be coupled to each other.

 <Fourth Embodiment>

In the embodiment, the latch 24 is fixed to the lower side of the second plate body 22, and the screw member 23 is fixed to the upper surface 211 of the first plate body 21. Thus, the first plate body 21 and the second plate body 22 can be connected and fixed together by the combination of the screw member 23 and the plug pin 24. In addition, in the embodiment, if the thickness of the screw head 231 is greater than the spacing S between the fork member 242 and the second plate 22, when the fork member 242 is inserted to the right, the fork member 242 Then, the screw head 231 and the fork member 242 are pressed against each other to be bent downward. As a result, the first plate body 21 or the second plate body 22 may be slightly deformed, especially when the first plate body 21 and the second plate body 22 are made of wood, plastic, rubber, resin, etc. When the shield is flexible or flexible, the deformation of the first plate 21 and the second plate 22 is more obvious. In other embodiments, the screw member 23 and the first plate body 21 may also be integrally formed.

Viewed from the side view of the present embodiment, the height HI of the root portion 242A is greater than the height H2 of the end portion 242B, and therefore, the circumferential circumference of the end portion 242B is smaller than the circumferential circumference of the root portion 242A. From another point of view, the branch portion 242C of the forked member 242 is a free end at the end portion 242B, and the thickness of the end portion 242B is thinner than the root portion 242A of the branch portion 242C. In this way, when the plug 24 is inserted to the right, the screw head 231 generates a large friction force at the root portion 242A; this structure has an advantage in that the fork member is inserted into the right direction, the fork member The friction between the 242 and the screw head 231 is variable and adjustable, and the free end of the fork member 242 (ie, the end portion 242B) can be thinned to facilitate the pin 24 and the screw member 23. Assembly. That is to say, when the pin 24 is inserted to the right, the frictional force thereof becomes tighter and the combined mechanical strength becomes larger and larger. In other embodiments, as shown in FIG. 6B, the branch portion 242C has an arc shape on the upper side between the flange portion 242A and the end portion 242B. Of course, other regular or irregular shapes may be used.

In this way, when the fixing component 2411 is locked to the second board 22, the accommodating space 245 can be used to limit and accommodate the wood chips (not labeled) generated by the fixing component 2411 during the rotational locking. Therefore, the plurality of wood chips do not press the body 241, causing the pin 24 to be skewed and unable to be accurately positioned.

In this embodiment, the accommodating space 245 is tapered. In other embodiments, the accommodating space 245 may also be an inverted cone (as shown in FIG. 8) or a cylindrical shape (as shown in FIG. 9). ). In the embodiment shown in FIG. 9, the accommodating space 245 defines a diameter D1 above the fixing element 2411.

 <8th to 15th embodiment>

As shown in FIG. 11 and FIG. 12, the end portion 242B of the two branch portions 242C defines a lead angle θ for facilitating the assembly and assembly of the plug 24 and the screw member 23. In addition, the fork component 242 is provided with a plurality of first coupling components 247, and the plurality of first coupling components 247 are periodically disposed on the two branch portions 242C of the fork component 242. When the 242 is combined with the screw member 23, the plurality of first coupling members 247 can be sequentially abutted with the screw rod 232; That is, the first coupling elements 247 on each branch portion 242C are aligned in a straight line, and the first coupling member 247 on the different branch portion 242C can be used to clamp the screw rod 232; When the 23 moves to the left, the first coupling element 247 on the distinct branch portion 242C can sequentially contact the screw rod 232. Here, the first coupling element 247 has an arc shape and protrudes from the two branch portions 242C. In other embodiments, the first connecting member 247 may of course also be a concave structure. Moreover, the width D4 of each of the first coupling elements 247 is less than or equal to the diameter of the screw rod 232.

That is, the screw rod 232 can be adjusted to move to any position of the branch portion 242C at any time, and thus, the combination of the screw member 23 and the bolt 24 is adjustable.

 As shown in FIG. 13, the plurality of first coupling elements 247 on the different two branch portions 242C are gradually reduced in pitch (ie, the closer to the body 241, the smaller the pitch), so that the plurality of the two branch portions 242C The first coupling elements 247 are arranged in a V shape. As a result, when the screw member 23 is moved to the left, the screw rod 232 is subjected to more and more resistance. Here, the two branch portions 242C may have appropriate flexibility.

 As shown in FIG. 14, the fork element 242 is not provided with the first coupling element 247. Further, the pitch of the distinct two branch portions 242C of the fork member 242 is gradually reduced (i.e., the closer to the body 241, the smaller the pitch).

 As shown in FIG. 15, the latch 24 further includes a notch groove 248 at the root 242A of the fork member 242. When the screw member 23 is moved to the left and enters the bottommost portion, the notch groove 248 can be used to accommodate the screw rod 232 and restrict the movement of the screw rod 232.

In the present embodiment, the number of the screw members 23 is three, which is more than that of the foregoing embodiment, so that the mechanical strength of the bolt 24 and the screw member 23 is large.

 Moreover, in the present embodiment, the number of second coupling elements 249 on each branch portion 242C is equal to the number of the screw rods 232; in other embodiments, the second coupling elements on each branch portion 242C The number of 249 can also be greater than the number of the screw rods 232, so that the screw members 23 can be selectively placed in different positions. Also, the width D6 of the second coupling member 249 is greater than or equal to the diameter of the screw shaft 232.

 In addition, the second coupling element 249 can also be triangular serrated (as shown in FIG. 20), thereby achieving the purpose of accommodating and restraining the screw rod 232. As shown in Fig. 21, the second coupling elements 249 on the different branch portions 242C are disposed at mutually staggered positions. Therefore, the second coupling members 249 on the different two branch portions 242C do not correspond to each other. For the same reason, the branch portion 242C of the present embodiment can also be provided with more second coupling members 249 than the number of the screw members 23.

As shown in FIG. 22, the plurality of second coupling members 249 are disposed only on one of the branch portions 242C of the fork member 242. As shown in FIG. 23, a plurality of first splicing elements 247 and a plurality of second coupling elements 249 are disposed on the branch portion 242C of each of the fork members 242. In this embodiment, the first coupling element 247 is a convex structure, and the second coupling element 249 is a concave structure. When the screw member 23 moves to the left, the plurality of first coupling members 247 can be used to apply a plurality of continuous and slight resistances to the screw rod 232, when the three screw rods 232 correspond to the plurality of second couplings When the component 249 is used, the plurality of second coupling components 249 can be used to receive and restrain the three screw rods 232 to prevent the screw member 23 from being separated from and separated from the plug pins 24.

 As shown in FIG. 24, the plurality of first coupling elements 247 are arranged in a V shape, and the plurality of second coupling elements 249 are also arranged in a V shape so that the plurality of first couplings on the different two branch portions 242C are arranged. The pitch of the elements 247 is gradually reduced (i.e., the closer the pitch is to the body 241), the spacing of the plurality of second coupling elements 249 on the distinct two branch portions 242C is also gradually reduced. In this way, the fork member 242 can be matched and abutted with the screw rods 232 of different diameters at the same time.

 As shown in Fig. 25, the fork member 242 is provided with a plurality of second coupling members 249 arranged in a V shape, but the first coupling members are not provided.

 Finally, the fork members 242 of the above embodiment each have two branch portions 242C, but in other embodiments, the branch portions 242C of the fork member 242 may of course be three, four, or even more. In this way, the latch 24 can be combined with more screws 23 to make the combined mechanical strength of the first plate 21 and the second plate 22 stronger and more stable.

 In summary, the fastener assembly structure of the present invention utilizes the disassembly and assembly of the latch 24 and the at least one screw member 23 to make the first plate body 21 and the second plate body 22 simple and fast. Separate or combine with each other. Therefore, when the fastener group structure of the present invention is applied to a toy structure, an assembled furniture, a kitchen refuse, a combination house, an interior decoration, a mechanical structural member, a support structure of a civil construction, or a power machine, an aircraft, etc. The utility model can have the advantages of rapid decomposition, combination and multiple assembly between a plurality of structural members or plate bodies. Moreover, even if the fastener group structure is decomposed and combined a plurality of times, it does not cause looseness or falling. Therefore, the stability and reliability of the structure are greatly increased compared with the conventional screw, so it has a huge commercial application potential.
