Detailed Description

The utility model is further described with reference to fig. 1 to 7:

A microcellular furniture connecting piece as shown in fig. 1, 2 and 3 comprises a connecting sleeve 1, a connecting rod 2 and a fixing pin 3. In this embodiment, the fixing pin 3 is a pin having a diameter of 3 mm.

As shown in fig. 4, the connection sleeve 1 has a cylindrical shape. The outer surface is smooth. The tail of the connecting sleeve 1 is provided with more than 1 mounting holes 11 which allow the fixing pins 3 to pass through. In order to facilitate the installation, the installation holes 11 can be easily found, and the installation holes 11 can be arranged in a plurality according to the requirement.

As shown in fig. 5, the connecting rod 2 includes a connecting post 21 and a fixing portion 22, and the end of the connecting post 21 is provided with a chucking barb 211. The fixing portion 22 is provided on an outer surface thereof with a first external thread 221. The connecting rod 2 can be fastened by means of the first external thread 221 in a pre-opened circular hole in the plate. The connecting sleeve 1 and the connecting rod 2 can be made of stainless steel, aluminum alloy or other materials, and in this embodiment, the connecting sleeve 1 and the connecting rod 2 are made of plastic materials.

In order to facilitate the tightening of the connecting rod 2 to the plate, the lower end of the connecting post 21 of the connecting rod 2 is provided with a polygonal boss 23. The polygonal boss 23 is a spanner position, so that an installer can screw the connecting pull rod 2 by using a tool conveniently. The polygonal boss 23 is typically a quadrangular boss, a hexagonal boss, an octagonal boss, or the like, and in this embodiment, a hexagonal boss is used.

As shown in fig. 4, the middle of the connection sleeve 1 is provided with a cavity 12 accommodating the connection post 21. An elastic clamp 13 is arranged in the middle upper part of the cavity 12, and a tooth-shaped clamping groove 131 matched with the clamping barb 211 is arranged in the elastic clamp 13. The number of the clamping barbs 211 and the tooth-shaped clamping grooves 131 is plural, and the distance between two adjacent clamping barbs 211 or tooth-shaped clamping grooves 131 can be set according to the needs, preferably 0.5 mm-1 mm. The purpose of tightly arranging the plurality of chucking barbs 211 and the toothed clamping grooves 131 is as follows: firstly, the two are matched more firmly; secondly, after the connecting piece is installed on the plates, the gap between the plates after the plates are combined is smaller.

The lower end of the cavity 12 of the connecting sleeve 1 is provided with an internal hexagonal hole 14. When the coupling sleeve 1 is mounted to the panel, the mounting tool can easily rotate the coupling sleeve 1 through the inner hexagonal hole 14, thereby enabling the fixing pin 3 to be inserted into the mounting hole 11 more conveniently.

As shown in fig. 4 and 6, the elastic clip 13 includes more than 2 elastic cards 132, the tooth-shaped card slots 131 are disposed on the elastic cards 132, and the plurality of elastic cards 132 may be disposed in a manner of circumferentially uniformly distributed, etc., in this embodiment, the number of the elastic cards 132 is 3.

As shown in fig. 4, a clearance space 31 is reserved at the rear of the elastic card 132, and when the elastic card 132 is convenient to detach, the elastic card 132 is unfolded by the detaching tool, and the elastic card 132 is tilted backwards.

When the elastic clamp is detached, a detaching tool is conveniently pressed into the round cavity surrounded by the elastic clamp 132, and the upper end of the elastic clamp 13 is provided with a guide angle 1321.

The mounting and dismounting process of the utility model is as follows:

when in installation:

As shown in fig. 7, first, the connecting sleeve 1 is put into the pre-opened fitting circular hole of the first plate member 100; then, the connecting sleeve 1 is rotated by an installation tool such as an allen wrench, so that the installation hole 11 on the connecting sleeve 1 is aligned with the pre-opened pin hole of the first plate 100; then the mounting pin 3 is inserted into the pin hole and the mounting hole, and the connecting sleeve 1 is fixed;

Similarly, the fixing portion 22 of the connecting rod 2 is tightened into the circular hole formed in the second plate 200 by screwing the polygonal boss 23 using an installation tool such as a wrench, and the connecting rod 2 can be firmly fixed to the second plate 200 because the first external screw 221 is provided on the outer wall of the fixing portion 22.

Finally, the first plate 100 with the connecting sleeve 1 and the second plate 200 with the connecting pull rod 2 are aligned, namely, the connecting post 21 of the connecting pull rod 2 is aligned with the cavity 12 of the connecting sleeve 1, then the first plate 100 and the second plate 200 are pressed tightly, and the clamping barbs 211 at the tail ends of the connecting post 21 are matched and clamped with the tooth-shaped clamping grooves of the elastic clamping pieces 132, so that the first plate 100 and the second plate 200 are fixedly connected. It can be seen that the connection process of the first plate 100 and the second plate 200 is convenient and quick.

When the disassembly is carried out:

Pulling out the fixing pin 3 pulls the first plate 100 and the second plate 200 apart. At this time, the connecting sleeve 1 is tightly sleeved on the connecting pull rod 2, as shown in fig. 6, the bottom end of the connecting sleeve is provided with a chamfer disassembling tool 4 or a cross screwdriver, and the inner part of a round cavity surrounded by the elastic clamping piece 132 is pressed in, so that the elastic clamping piece 132 is outwards spread, the clamping barb 211 of the connecting pull rod 2 is separated from the tooth-shaped clamping groove 131 on the connecting sleeve 1, and after separation, the connecting pull rod 2 can be conveniently pulled out from the connecting sleeve 1, thereby realizing the separation of the connecting sleeve 1 and the connecting pull rod 2. After the disassembling tool 4 withdraws the round cavity enclosed by the elastic card 132, the elastic card 132 is folded inwards, so that the connecting sleeve 1 is restored to the original state.

From the above, the microporous furniture connecting piece can realize quick and nondestructive disassembly of the connecting piece.

In addition, the plate mounting hole (pin hole) formed in the first plate 100 is small, and in this embodiment, since the diameter of the pin is 3mm, the diameter of the pin hole is also about 3mm, and after the pin is mounted, the pin hole is covered by the head of the pin and is completely invisible, so that the plate mounting hole has almost no influence on the overall aesthetic degree of the plate. The utility model has simple structure and low cost, and can bear common price furniture.

The above embodiments are only preferred examples of the present utility model and are not intended to limit the scope of the present utility model, so that all equivalent changes or modifications of the structure, characteristics and principles described in the claims are included in the scope of the present utility model.
