Abstract

The utility model is suitable for the technical field of a connecting piece and provides a square tube corner connecting piece. The square tube corner connecting piece comprises a base; four spring sheets are respectively arranged on the two mutually vertical end faces of the base, and are surrounded into an embedding part; the shape of the embedding part is adapted with that of a square tube inner hole, a first threaded hole is arranged on a square tube, a second threaded hole is arranged on one spring sheet adjacent to the first threaded hole, the size of the second threaded hole is consistent with that of the first threaded hole, and the second threaded hole and the first threaded hole are respectively matched with a thread fastening piece. The provided square tube corner connecting piece has the characteristics that: the connecting piece is firmly connected with two square tubes by the thread fastening piece and the spring sheets, so as to realize the purpose of corner connection of the two square tubes; when in disassembling, the connecting piece can be disconnected with the square tubes only by screwing out the thread fastening piece; the connecting piece has simple structure, leads reliable connection, is convenient to be disassembled, and has high popularization as well as application values.

Description

The square tube Corner Link

Technical field

The utility model belongs to the link technical field, relates in particular to a kind of square tube Corner Link.

Background technique

The general more complicated of link structure of two square tubes of connection of the prior art, and connect insecurely, often occur phenomenon loosening even that break away between link and the square tube, and dismounting is also extremely inconvenient.

The model utility content

Technical problem to be solved in the utility model be to provide a kind of simple in structure, connect square tube Corner Link reliable, convenient disassembly.

The utility model is to realize like this, a kind of square tube Corner Link, comprise a pedestal, on two mutually perpendicular end faces of described pedestal, be respectively equipped with four shell fragments, described four shell fragments enclose one with square tube in the suitable Embedded Division of hole shape, offer one first tapped hole on the described square tube, on the adjacent shell fragment of described first tapped hole, offer one with described first tapped hole second tapped hole of the same size, and described second tapped hole and first tapped hole cooperate with a threaded fastener respectively.

Described pedestal is square, and its cross-sectional dimension is consistent with the cross-sectional dimension of square tube.

Described threaded fastener is a Cock screw.

The square tube Corner Link that the utility model provides is fastenedly connected link and two square tubes by threaded fastener and shell fragment, has realized the corner purpose of connecting of two square tubes; When dismounting, only threaded fastener need be screwed out and link and square tube can be taken apart; This link is simple in structure, connection is reliable, convenient disassembly, has the excellent popularization using value.

Description of drawings

Fig. 1 is the link that provides of the utility model embodiment and the decomposing schematic representation of square tube;

Fig. 2 is the sectional view that the link that provides of the utility model embodiment and square tube are assembled together.

Embodiment

In order to make the purpose of this utility model, technological scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Consult Fig. 1～shown in Figure 2, the square tube Corner Link that the utility model embodiment provides, comprise a pedestal 1, on two mutually perpendicular end faces of described pedestal 1, be respectively equipped with four shell fragments 21, described four shell fragments 21 enclose one with square tube 3 in the suitable Embedded Divisions 2 of hole shape, offer one first tapped hole 31 on the described square tube 3, on the adjacent shell fragment 21 of described first tapped hole 31, offer one with described first tapped hole, 31 second tapped holes 211 of the same size, and described second tapped hole 211 and first tapped hole 31 cooperate with a threaded fastener 4 respectively.

Particularly, in the present embodiment, described pedestal 1 is square, and its cross-sectional dimension is consistent with the cross-sectional dimension of square tube 3, like this, has guaranteed that the profile after pedestal 1 links together two square tubes 3 is coherent, attractive in appearance; Described threaded fastener 4 is a Cock screw 41, described Cock screw 41 does not have nut, can screw in fully in the square tube 3, can the shell fragment of being located in the square tube 3 21 fully be pushed, make Embedded Division 2 distending laterally to greatest extent, thereby Embedded Division 2 and square tube 3 are fastenedly connected.

The square tube Corner Link that the utility model embodiment is provided and the concrete Placement of square tube are: the Embedded Division on the pedestal 12 is inserted respectively in two square tubes 3, use HEX HEAD CAP SCREWS spanner (not shown) Cock screw 41 to be screwed in the tapped hole 211 of the tapped hole 31 of square tubes 3 and shell fragment 21 then, Cock screw 41 can push the shell fragment 21 relative with it in the screw-in process, make Embedded Division 2 distending laterally, thereby Embedded Division 2 is fastened in the square tube 3, has realized fixedlying connected of Embedded Division 2 and square tube 3.

The square tube Corner Link that the utility model provides is fastenedly connected link and two square tubes 3 by threaded fastener 4 and shell fragment 21, has realized the corner purpose of connecting of two square tubes 3; When dismounting, only threaded fastener 4 need be screwed out, then Embedded Division 2 is extracted from square tube 3, link can be separated with square tube 3; This link is simple in structure, connection is reliable, convenient disassembly, has the excellent popularization using value.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.

Claims

1, a kind of square tube Corner Link, it is characterized in that: comprise a pedestal, on two mutually perpendicular end faces of described pedestal, be respectively equipped with four shell fragments, described four shell fragments enclose one with square tube in the suitable Embedded Division of hole shape, offer one first tapped hole on the described square tube, on the adjacent shell fragment of described first tapped hole, offer one with described first tapped hole second tapped hole of the same size, and described second tapped hole and first tapped hole cooperate with a threaded fastener respectively.

2, square tube Corner Link as claimed in claim 1 is characterized in that: described pedestal is square, and its cross-sectional dimension is consistent with the cross-sectional dimension of square tube.
