Abstract
The utility model relates to a connecting fastener which is mainly suitable for panel furniture. The utility model comprises a pin of which the top is provided with a cross slot. The bottom of the pin is provided with a radial U-shaped slot. The inner end of the U-shaped slot is provided with a counter bore. The head of a conicity pin with a dilation sleeve is arranged in the counter bore. The rotating pin makes the conicity pin drive the dilation sleeve to be dilated in order to connect the two plates. The conicity pin and the dilation sleeve of the connecting fastener are in buckling connection and only need to be inserted in the counter bore. The utility model is convenient to assemble. A hemispherical counter bore is arranged on the pin. The hemispherical head of the conicity pin is arranged in the counter bore of the pin. The utility model changes the point or line contact in the prior art to surface contact, and the assembly is tighter and firmer.
Description
The utility model relates to a kind of connection fastening piece that mainly is applicable to plate fitment.
The connection fastening piece of existing plate fitment generally is made up of pin, screw and nut.The end face of its pin is provided with cross recess, and the lower end is provided with radially U-groove bevel.Because the internal surface of U-groove bevel is an arc, the head of plain screw is just some contact or line contact in U-groove bevel, causes the connection of furniture-plates insecure.In addition, must place nut at Kong Zhongxian when connecting two furniture-plates, screw screw again, connect pin then, it is not too convenient to assemble.
The purpose of this utility model aims to provide a kind of connection fastening piece of simple in structure, easy to assembly, the plate fitment that is connected firmly, to overcome the deficiencies in the prior art part.
A kind of connection fastening piece that mainly is applicable to plate fitment by this purpose design comprises top band cross recessed pin, and the lower end of pin is provided with radially U-groove bevel, and its structure characteristic is that the medial extremity of described pin U-groove bevel is provided with a counterbore; The head of the tapering pin of band expansion sleeve is arranged in the described counterbore; The rotation pin is dilated by tapering pin drive expansion sleeve two boards is connected together.
The head of described counterbore and tapering pin adapts, and is generally taper or hemisphere.One end of described tapering pin is a cone, and the other end is cone or hemisphere.Described expansion sleeve forms for left and right sides two halves fasten; The surface is provided with colludes shape projection or lines; The lower end is provided with the axial groove that can dilate.The expansion sleeve surface also is provided with positioning convex ring or projection, with the degree of depth of determining that expansion sleeve inserts in the hole.Expansion sleeve central authorities are provided with the groove that adapts with tapering pin profile.
The tapering pin of this connection fastening piece and expansion sleeve are for being fastened and connected, and inserting in the hole gets final product, and assemble very convenient, and pin is provided with counterbore, the hemispherical nose of tapering pin places the counterbore of pin, and the point or the line that change prior art contact to the face contact, make and assemble more close and firm.
Accompanying drawing is the utility model one example structure schematic representation.
Fig. 1-Fig. 3 be respectively pin the master, bow, right elevation; Fig. 4 is the A-A sectional view of Fig. 1.
Fig. 5 is the structural representation of tapering pin.
Fig. 6-8 is respectively plan view, open mode figure and the left view thereof of expansion sleeve.
Fig. 9-Figure 11 connects the assembly process schematic representation of two furniture-plates for this fastening piece.
Referring to Fig. 1-Fig. 4, the top of pin 1 is provided with the cross recess 4 of screw-driver, and the lower end is provided with radially U-groove bevel 2, and the medial extremity of U-groove bevel is provided with a hemisphere counterbore 3.Referring to Fig. 5, an end of tapering pin 5 is a cone 6, and the other end is a hemisphere 7.Referring to Fig. 6-Fig. 8, expansion sleeve 8 forms for left and right sides two halves fasten, and the surface is provided with colludes shape projection 9 and flexuose screw thread, the frictional force when cooperating with the hole with increase.Its lower end is provided with the axial groove 10 that can dilate.Its surface also is provided with positioning convex ring 11 or projection, with the degree of depth of determining that expansion sleeve inserts in the hole.Expansion sleeve central authorities are provided with the groove 12 that adapts with tapering pin profile, to place the tapering pin.During installation, the tapering pin 5 of pin 1 and band expansion sleeve 8 is put into separately hole respectively, the head of tapering pin is inserted the U-groove bevel 2 of pin 1 again, rotation pin 1 drives expansion sleeves 8 by tapering pin 5 and dilates and make two boards connect together (shown in Fig. 9-11).Expansion sleeve can adopt rubber or plastic materials to make.
Another embodiment of the present utility model inserts existing fastening screw trip bolt in the counterbore of medial extremity of pin U-groove bevel, and the rotation pin drives fastening screw trip bolt and nut links together two boards.(promptly do not adopt tapering pin and expansion sleeve structure.) its counterbore also should adapt with the head of fastening screw trip bolt, is generally cylindricality, taper or hemisphere.
