Description

a connecting buckle

Technical field:

The utility model relates to furniture fittings, in particular to a connecting buckle.

Background technique:

In the prior art, most of the furniture boards use screw screws to achieve a firm connection. This connection method has the advantages of firm connection, easy installation and disassembly, etc., but there are also the following disadvantages: when installing and removing the screw screws, it is necessary to use a screwdriver to work hard. 1. Time-consuming screwing in and out of the furniture board, repeated many times, will leave a hole on the board and the place on the board can no longer be used, thus affecting the use of the furniture board, unsightly, high cost, and inconvenient to assemble and disassemble.

Utility model content:

The purpose of the utility model is to improve the deficiencies of the prior art, and provide a hand-pressed non-extractable tool-free connecting buckle applicable to furniture panels, which has scientific structure design, low production cost and convenient use.

In order to achieve the above object, the utility model adopts the following technical scheme, which includes a connecting ring and a connecting bolt, one end of the connecting ring is provided with a flange, the ring axis hole of the connecting ring is a connecting hole, and the outer wall of the connecting ring is provided with a There are annular ratchets, the tail end of the connecting bolt is provided with a cap, the front end of the connecting bolt is a tapered end, the tapered end of the connecting bolt matches the connecting hole on the connecting ring, and the largest outer diameter of the tapered end The diameter is greater than the maximum inner diameter of the connecting hole, and the tapered end is axially provided with a groove that can make the tapered end shrink when matched with the connecting hole.

The ratchets are inverted teeth.

There is at least one groove.

The outer contour of the flange is circular, or rectangular, or oval.

The connecting buckle is a hand-pressed non-pulling connecting buckle nailed between furniture boards. When in use, the connecting ring is buried on one part, so that a perforation is formed on the part, a hole is set on the other part, and the connecting bolt is passed through the hole, and then, by passing the tapered end of the connecting bolt through the According to inserting in the connecting hole on the connecting ring, since the maximum outer diameter of the tapered end is greater than the inner diameter of the connecting hole, the connecting bolt cannot withdraw from the connecting hole, thus, the two parts can be connected together.

The beneficial effects of the utility model are: the conical end of the connecting bolt matches the connecting hole on the connecting ring, and the maximum outer diameter of the conical end is larger than the maximum inner diameter of the connecting hole, and the conical end is axially provided with a The groove that shrinks when the tapered end matches the connecting hole, because the hole for piercing the connecting bolt on the furniture can be made by the furniture manufacturer, and the connecting ring is also buried in the furniture during the manufacturer's production, so the quality of the opening It can be guaranteed, and the opening will not affect the appearance and function of the furniture. The two parts are connected by connecting bolts, and the connection reliability is also strong. The connection bolt hole and the embedded connection ring are reserved on the furniture, and the user needs to use the connection bolt to pass through the connection bolt, which can be completed very conveniently. Compared with the existing technology, when the user needs to connect two parts, now In the case of punching holes and nails on the parts, the connecting buckle saves time and effort when used, and the connected furniture parts are also beautiful and firm.

Description of drawings:

Fig. 1 is a structural representation of the utility model;

Fig. 2 is the structural representation of another direction of the utility model;

Fig. 3 is a schematic diagram of an exploded structure of the utility model.

Detailed ways:

See Fig. 1 to Fig. 3 and show: the utility model includes in order to realize above-mentioned purpose, the utility model adopts following technical scheme, it comprises connecting ring 1 and connecting bolt 2, and one end of described connecting ring 1 is provided with flange 11, The ring axis hole of the connecting ring 1 is the connecting hole 4, the outer wall of the connecting ring 1 is provided with an annular ratchet 3, the tail end of the connecting bolt 2 is provided with a cap 21, and the front end of the connecting bolt 2 is a tapered end 6, The tapered end 6 of the connecting bolt 2 matches the connecting hole 4 on the connecting ring 1, and the maximum outer diameter of the tapered end 6 is greater than the maximum inner diameter of the connecting hole 4, so that the tapered end of the connecting bolt 2 can be better made. The conical end 6 slides into the connecting hole 4 of the connecting ring 1 when pressed by hand and is tightly connected, and will not come out from the connecting hole 4 and lose the connection function. Groove 61 that contracts when holes 4 are mated.

There is at least one groove 61. When the tapered end 6 is inserted into the connection hole 4, the gap between the grooves 61 can shrink the tapered end 6 and fix it through the connection hole 4.

The flange 11 is ring-shaped.

The use method of this connecting buckle: firstly bury the connecting ring 1 in the furniture board, set a hole on another furniture board, then make the hole on the furniture board correspond to the connecting hole 4 of the connecting ring 1, and then put the The tapered end 6 of the connecting bolt 2 is inserted into the connecting hole 4 through the hole on the furniture board, and finally the tapered end 6 of the connecting bolt 2 slides out of the connecting hole 4 of the connecting ring 1 under the pressure of the hand to be stuck , the two furniture boards can be tightly connected together.

The ratchet 3 is an inverted tooth that stops in the direction of coming out of the embedded hole provided on the furniture, and the stop plane of each ratchet is on the flange side of the connecting ring.

The above is only a preferred embodiment of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the utility model patent application scope are all included in the utility model patent application scope .
