Abstract

The utility model relates to the furniture accessories, in particular to a novel connecting buckle, which comprises a connecting ring and a connecting bolt. One end of the connecting ring is provided with a flange; the central hole of the annular shaft of the connecting ring is a connecting hole; the outer wall of the connecting ring is provided with annular teeth; the tai; end of the connecting bolt is provided with a bolt cap; the front end of the connecting bolt is provided with a tapered end; the tapered end of the connecting bolt matches with the connecting hole on the connecting ring; the maximum outside diameter of the tapered end is larger than the maximum inside diameter of the connecting hole; and the tapered end is provided with a groove in the axial direction for the tapered end to shrink when matching with the connecting hole. The utility model has the advantages of scientific structural design, low production cost and convenient use.

Description

A kind of junction button

Technical field:

The utility model relates to furniture part, especially a kind of junction button.

Background technique:

In the prior art, great majority adopt spiral nail to realize firm connection on furniture-plates, this Placement has advantage such as be connected firmly, installing/dismounting is simple, but also there is following shortcoming: during the installing/dismounting spiral nail, need require great effort with screw-driver, time-consumingly screw in screw out furniture-plates, repeated multiple times can stay just on the plate that this place can not use again on hole and the plate, thereby influence the use of furniture-plates, not attractive in appearance, cost is high, loading and unloading just neither.

The model utility content:

The purpose of this utility model is to improve the deficiencies in the prior art, and provides a kind of applicable to the non-instrument of the exempting from junction button of extracting of hand push type between furniture-plates and the plate, its scientific structure design, and cost of production is low, easy to use.

For achieving the above object, the utility model adopts following technological scheme, it comprises connecting ring and coupling bar, one end of described connecting ring is provided with flange, the ring axle center hole of connecting ring is an attachment hole, offer annular ratchet on the outer wall of connecting ring, the tail end of coupling bar is provided with the bolt cap, the front end of coupling bar is a cone-shaped end, the cone-shaped end of coupling bar and the attachment hole on the connecting ring are complementary, and the maximum outside diameter of cone-shaped end is greater than the maximum inner diameter of attachment hole, and cone-shaped end axially offers the groove that shrinks in the time of can making cone-shaped end and attachment hole coupling.

Described ratchet is the tooth of falling the shape.

Described groove has one at least.

The external frame of described flange is circular, or rectangle, or oval.

This junction button be a kind of hand push type non-extract bind junction button between furniture-plates and the plate.During use, connecting ring is embedded on the parts, make to form a perforation on these parts, on another parts, establish the hole, coupling bar is located in this hole, then, by the cone-shaped end of coupling bar being handled, because the external diameter of the maximum of cone-shaped end makes coupling bar not withdraw from from attachment hole greater than the internal diameter of attachment hole by in the attachment hole that inserts on the connecting ring, thus, two parts can be linked together.

The utility model beneficial effect is: the cone-shaped end of coupling bar and the attachment hole on the connecting ring are complementary, and the maximum outside diameter of cone-shaped end is greater than the maximum inner diameter of attachment hole, cone-shaped end axially offers the groove that shrinks in the time of can making cone-shaped end and attachment hole coupling, because wearing the hole of coupling bar on furniture is to be made by furniture producer, and connecting ring is also by being embedded in the manufacturer production in the furniture, therefore, its perforate quality can guarantee, and perforate can not have influence on the attractive in appearance and function of furniture, connect two parts by coupling bar, its connection reliability is also stronger.On furniture, reserve and connect keyhole and bury connecting ring underground, there is the user to wear coupling bar in the use that needs connect, just can finish the field easily, compared with prior art, when the user connects two parts when needs, punch the situation of drift bolt on the parts now, this junction button uses also and saves time, laborsaving, and the furniture parts that couples together is also very attractive in appearance, firm.

Description of drawings:

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

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

Fig. 3 is a decomposition texture schematic representation of the present utility model.

Embodiment:

See that Fig. 1 is to shown in Figure 3: the utility model comprises for achieving the above object, the utility model adopts following technological scheme, it comprises connecting ring 1 and coupling bar 2, one end of described connecting ring 1 is provided with flange 11, the ring axle center hole of connecting ring 1 is an attachment hole 4, offer annular ratchet 3 on the outer wall of connecting ring 1, the tail end of coupling bar 2 is provided with bolt cap 21, the front end of coupling bar 2 is a cone-shaped end 6, the cone-shaped end 6 of coupling bar 2 is complementary with the attachment hole 4 on the connecting ring 1, and the maximum outside diameter of cone-shaped end 6 is greater than the maximum inner diameter of attachment hole 4, be convenient to make better the cone-shaped end 6 of coupling bar 2 to push attachment hole 4 and the closely connection that slips into connecting ring 1 down at hand like this, and can not deviate from and lose interconnect function from attachment hole 4, cone-shaped end 6 axially offers the groove 61 that shrinks in the time of can making cone-shaped end and attachment hole 4 couplings.

Described groove 61 has one at least, and is when cone-shaped end 6 is inserted attachment hole 4, because the gap of groove 61 can make cone-shaped end 6 shrink, fixing by attachment hole 4.

Described flange 11 is an annular.

The using method of this junction button: earlier with connecting ring 1 landfill in furniture-plates, on another furniture-plates, establish the hole, corresponding the hole of establishing on this furniture-plates then with the attachment hole 4 of connecting ring 1, insert in the attachment hole 4 in the hole that the cone-shaped end 6 of coupling bar 2 is passed on the furniture-plates again, block by depressing in the attachment hole 4 that the cone-shaped end 6 that makes coupling bar 2 skids off connecting ring 1 at last, just two furniture-plates closely can have been linked together at hand.

Described ratchet 3 is that the stop surfaces of each ratchet is in flange one side of connecting ring at the tooth of being offered from furniture of falling the shape of deviating from stop on the direction the hole of burying underground.

The above only is preferred embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
