Description

TECHNICAL FIELD

[0001] The utility model relates to furniture technical field, namely invisible connecting piece. BACKGROUND

[0002] In prior art, the connecting between the two side vertical plates of plate furniture has invisible connection and visible connection, the invisible connection is that the connecting piece cannot be seen after connection and is hidden in the plate, and the invisible connection is preferred in the market. SUMMARY

[0003] The utility model discloses a simple structure and low cost invisible connecting piece.

[0004] The technical solution of the utility model is as follows: an invisible connecting piece comprises a partition piece installed in the end of a partition and a lapping piece installed opposite to the end of the partition.

[0005] The above scheme further comprises:

[0006] The inside of the insertion hole has a pointed hole for accommodating the hook tip of the elastic hook.

[0007] The elastic hook has a batten body at the rear end, and the rear end of the batten body is fixedly connected to the upper end of the pipe body.

[0008] The pipe body and the second pipe body are circular pipes.

[0009] The utility model has the advantages that the partition piece is composed of the pipe body and the elastic hook, and has the advantages of simple structure, convenient processing and low cost.

[0010] The device has simple overall structure and low cost.

[0011] The embodiments of the utility model will be further described in detail below with reference to the drawings. BRIEF DESCRIPTION OF DRAWINGS

[0012] Figure 1 is the structure diagram of the partition piece of the utility model.

[0013] Figure 2 This is a simplified structural diagram of the lap joint of this utility model.

[0014] Figure 3 yes Figure 2 Simplified diagram of the right-side structure.

[0015] Figure 4 yes Figure 2 Simplified structural diagram viewed from below.

[0016] Figure 5 This is a simplified diagram of the installation structure.

[0017] The components in the diagram are named as follows: tube body 1, elastic hook 2, slat body 3, second tube body 4, low platform 5, socket 6, pointed mouth 7, partition 8, plate surface 9. Detailed Implementation

[0018] See Figures 1-5 The concealed connector includes a partition member installed inside the partition end and an overlapping member installed inside the vertical plate opposite the partition end. The partition member includes a tube 1, which is a metal or plastic round tube. The outer surface of the tube 1 may have fine threads to increase friction with the wood holes. An elastic hook 2, preferably a metal steel sheet, is exposed at the end of the tube 1. A slat 3 is attached to the rear end of the elastic hook 2, and the rear end of the slat 3 is fixedly connected to the upper tube 1. The rear end fixes the drooping head at the front end, allowing the elastic hook 2 to have a flexible up-and-down swinging space. The elastic hook 2 and the slat 3 are integrally formed and are made of metal steel.

[0019] The connecting component is a second tube 4. The front end of the second tube 4 has a low platform 5, which is lower than the top of the outer circumference of the second tube 4. The platform is located at two-thirds of the tube's diameter. Behind the low platform 5 is a socket 6 for inserting the elastic hook 2. The socket 6 is preferably the same shape as the elastic hook 2, such as flat, but can also be round, rectangular, etc. The socket 6 is wider than the elastic hook 2 for easy insertion. The socket 6 is sealed around its perimeter and can be a plastic component, molded in one piece. The low platform 5 guides and supports the elastic hook 2; that is, the elastic hook 2 first touches the low platform 5 and then slides into the socket 6. After installation, the curved part of the elastic hook 2 finally rests on the socket 6. Inside the socket 6, at the lower end of the tube, there is a pointed opening 7 to accommodate the hook tip of the elastic hook, ensuring sufficient space within the second tube 4 to accommodate the elastic hook 2. If the hook tip is thicker or shorter, the pointed opening 7 can be omitted. The cost of this device is only one-third of that of the traditional method.

[0020] See Figure 5, the use method: the device is used for furniture partition invisible fixed connection, and is composed of a set of partition and lap joint. When installing, a plurality of groups are arranged along the width direction of the partition 8 at both ends of the partition 8. Now, taking one group at both ends of the partition 8 as an example: a hole is drilled in one end surface of the partition 8, and the partition piece is hammered in, and the elastic hook 2 is exposed; a hole is drilled on the board surface 9 abutting the end surface of the partition 8, and the lap joint is hammered in. At the same time, the partition piece and the lap joint are installed at the other end of the partition 8. When assembling, the partition 8 is held by hand, the elastic hook 2 is inserted into the socket 6 at the left end, the hook tip of the elastic hook 2 naturally slides into the sharp mouth 7, the other end of the partition 8 is moved from below to above below the installation hole, when the elastic hook 2 at the end is hooked on the low platform 5 (with a sound), the partition 8 is pressed down again, the elastic hook 2 slides into the socket 6, the hook tip of the elastic hook 2 naturally slides into the sharp mouth 7, and stable installation is realized. When disassembling, the partition 8 is lifted or knocked, and the elastic hook 2 can be pulled out, which is simple and convenient.

[0021] The above description is only a specific embodiment of the utility model, and various examples do not constitute limitation on the essential content of the utility model.
