technical field

The invention relates to a knock-fit positioning structure for assembly of modular furniture.

Background technique

Please refer to the assembly drawing of the combined furniture structure of the prior art shown in Fig. 1, the structural design shown in it is mainly to use metal laminated layer assembly to form storage cabinets, wardrobes and other storage items, the existing structure is mainly composed of The interlayer 30 and its four fixed end 50 structures, and the support rod 60 structure are assembled; the four ends of the interlayer 30 are provided with a cylindrical fixed end 50, and the inner edge of the fixed end 50 is formed to be wide at the bottom and narrow at the top. The notch design of the conical body, and the aforementioned fixed end 50 is equipped with a semicircular first tapping piece 51 and another semicircular second tapping piece 52, wherein each side of the first tapping piece 51 is protruded with a self-contained The protruding piece 511 that its circular diameter extends, and the second knocking piece 52 both sides are each concavely provided with a fitting portion 521 with the equal area of the convex piece 511, so that the aforementioned first knocking piece 51 and the second knocking piece 52 each sides Male and female collocations can be formed and grouped together, and the shape of the first knocking piece 51 and the second knocking piece 52 outer ring is designed to be a slightly upwardly inclined conical body with a wide bottom and a narrow top. In addition, the inner circular surfaces of the two semicircular bodies of the aforementioned first knocking piece 51 and the second knocking piece 52 are respectively provided with a pair of ring edges 53 of equal height, so that they can be knocked against the aforementioned first knocking piece 51 and the second knocking piece 52. After grouping, a protruding annular shape is formed in the inner circle; and the aforementioned support rod 60 is a rod body that forms the height position of the four ends of the support interlayer 30, and its feature is that the support rod 60 rod body is provided with multiple equal height interval Inner recessed ring groove 61, make aforementioned first tap piece 51 and the second knock piece 52 utilize the ring edge 53 of the inner circular surface of its two semicircular bodies after knocking group, cover and knock on ring groove 61 positioning, then Utilize the fixed ends 50 of the four ends of the aforesaid interlayer 30 to be inserted from the top, through the tapered design of the inner circular notch of the fixed end 50 and the sleeve of the outer ring tapered oblique body after the first knocking piece 51 and the second knocking piece 52 are knocked together. Connect, and reach the limit fixation effect of tight fit positioning after the two bottom ends contact.

As mentioned above, the assembly of existing structural modular furniture has the characteristics of high load and strong structure, which can be used to place heavier and more items, and because the four ends are all set, it is more matchable. The compartments 30 in different orientations are erected to extend and assemble in the horizontal direction to achieve the characteristics of continuous assembly, which is why it is widely used in the market. However, after referring to the structure assembly of the prior art shown in Fig. 2, the knock group design of the fixed end 50, the first knock piece 51 and the second knock piece 52 is used to fix the design on the support rod 60. The following disadvantages:

1. Complex structure and difficult assembly;

To assemble the structure of the prior art, the first tap piece 51 and the second tap piece 52 must be tapped on the support rod 60 first, and the ring edge 53 of the inner ring needs to be covered and tapped on the support rod 60. The positioning on the ring groove 61 can accurately make the four ends of the interlayer 30 be fixed at the same height on each support rod 60 . However, when assembling, the user cannot directly observe whether the ring edge 53 of the inner ring has accurately covered the ring groove on the support rod 60 after tapping the first tapping piece 51 and the second tapping piece 52. 61, the user must try to move up and down whether the first percussion piece 51 and the second percussion piece 52 after the percussion group can slide or be fixed on the support rod 60, to determine whether it is really positioned, thereby avoiding the different heights of the group. However, this situation requires experienced users to be familiar with it after all. For ordinary users, it is difficult to locate accurately. Therefore, the height of the alignment of the compartment 30 is often not the preset positioning height, resulting in the height of the four ends being different. One state or even the situation that the first knocking piece 51 and the second knocking piece 52 slip off on the support rod 60, thus causing the whole assembly process to start again; After the fixed end 50 of the end, it can be set up to stand. If there are not sufficient manpower, the first knocking piece 51 and the second knocking piece 52 are often positioned on the support rod 60 in the very complicated assembly process, and they will vibrate due to the operation process. The first tap piece 51 and the second tap piece 52 must be repositioned on the support rod 60 due to falling off, which often causes time-consuming and labor-intensive processing for the user to assemble, which is very inconvenient.

2. Replacement is troublesome and the design of components is highly restrictive;

After the assembly of the combined furniture structure in the prior art is completed, if the user needs to change the collocation and position of the cabinet layers of the overall structure to change other needs such as placement position or to meet different needs such as adding cabinet layers, the combined furniture must be dismantled and replaced. At the same time, for the partitions 30 in the same vertical direction, or the partitions 30 assembled on both sides, the user must completely detach the assemblies above the partitions 30 to be replaced one by one from each support bar 60, Only then can it be reassembled according to the required collocation, and even all the components need to be disassembled, thus further causing inconvenience to the user. In addition, the structural assembly of the combined furniture in the prior art will increase with the collocation of the partitions 30, and there will be more demands on the quantity of the first knocking piece 51 and the second knocking piece 52, but the first knocking piece of this type 51 and the second tapping piece 52 are designed as a male-female match to avoid assembly errors due to the requirements of its cone design, and because of factors such as cost, they are mainly made of plastic materials, which are high-loss materials. In case of repeated assembly, the first knocking piece 51 and the second knocking piece 52 after wear and tear can reduce the knocking tightness of its positioning or cause it to be unable to continue to be used. Therefore, the first knocking piece 51 and the second knocking piece The collocation of one male and one female of 52 will inevitably produce the situation of missing parts when the structure of the combined furniture of the prior art is assembled again, which is very inconvenient.

3. The compartment cannot be connected horizontally;

Also referring to the three-dimensional assembly diagram shown in Figure 3, as mentioned above, when the interlayer 30 is set at the same horizontal position where a support rod 60 is fixed, only one fixed end can be provided for positioning and assembly, but when multiple channels are required When the interlayer 30 must be connected at the same horizontal position, the existing structure cannot provide the effect of continuous connection. Only as shown in Figure 3, several connecting pieces 62 can be provided to complete the assembly of the array. The cabinets are connected with connecting pieces 62 . With this design, the user must spend more to buy at least two support rods 60 when connecting and installing. In addition to causing waste of materials and costs, it also consumes a lot of space and is not practical.
