Description

The two-way link of section bar

The utility model relates to a kind of connection set of section bar.

In the prior art, Patent Office of the People's Republic of China has announced that application number is called " the Show stand skeleton of being convenient to various combination " for " 91202882 ", name and application number is called " table cabinet frame equipment structure " two patent applications for " 91202907 ", name.They provide with a kind of two-way connector element, its quality of this member is thin, and it is very little to be used for connection profile place area, very easily takes place the bad connection phenomenon to occur because of the moving of framework, overload, repeated disassembled and assembled combination, also need a plurality of actions to finish in the operation, not convenient.

The purpose of this utility model is to provide a kind of and is connected reliably with section bar, two-way link fast.

The technical solution of the utility model is: have axial circular hole on the connecting body, be provided with the sliding axle that matches with circular-hole internal-wall in this axial circular hole, the right-hand member of this sliding axle is exposed to outside the connecting body and this end is provided with the contiguous block of radial protrusion, connecting body radially have a cylindrical hole, be provided with the runner that matches with circular-hole internal-wall in this cylindrical hole, this runner axially have an eccentric breach with the eccentric shaft of runner, this runner radially have a horizontal cut, the left end of described sliding axle is provided with interior projection, the radial length of projection is greater than the height of horizontal cut in being somebody's turn to do, and should be positioned at eccentric breach by interior projection, the radial length of the axle journal of projection and sliding axle is slightly less than the height of horizontal cut in connecting.

The utility model compared with prior art has following advantage:

(1). when using, the contiguous block of sliding axle right-hand member inserts in the opening slot of a vertical section bar, and connecting body inserts in the section bar opening slot of another root horizontal positioned, be positioned at the profile wall portion boring at runner place, the runner upper-end surface is exposed, rotating wheel, then horizontal cut inserts in the axle journal, because the effect of eccentric claw hook, the angle of swing of runner is big more, then spurs sliding axle more to the left, two orthogonal section bars are closely connected, the surface of contact of this linkage structure is big, so connected framework strength is big, fastness is strong.

(2). it is the joint that two section material frameworks have only a runner, is dismantling repeatedly, can not damage when making up, and the action of its operation is also few, so easy for installation.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing 1 is a structure front section view of the present utility model;

Accompanying drawing 2 is the A-A direction sectional view of accompanying drawing 1;

Accompanying drawing 3 is for after the runner dextrorotation of accompanying drawing 1 turn 90 degrees, A-A direction sectional view; Wherein:

[1]. spring; [2]. horizontal cut; [3]. runner; [4]. translot; [5]. interior projection; [6]. axle journal; [7]. connecting body; [8]. sliding axle; [9]. contiguous block; [10]. eccentric breach; [11]. claw hook; [12]. axial circular hole; [13]. hook in the wall body.

Embodiment: referring to accompanying drawing 1～3, have axial circular hole [12] on the connecting body [7], be provided with the cylindrical sliding axle [8] that matches with circular-hole internal-wall in this axial circular hole [12], make this sliding axle [8] to horizontally slip along described axial circular hole [12].The right-hand member of this sliding axle [8] is exposed to outside the connecting body [7] and this end is provided with the contiguous block [9] of radial protrusion, described contiguous block [9] is a cuboid, two bump is a circular arc, make after contiguous block [9] inserts vertical section bar opening slot, revolve the inside edge that to hook opening slot after turning 90 degrees by its bump.Connecting body [7] radially have a cylindrical hole, be provided with the runner [3] that matches with circular-hole internal-wall in this cylindrical hole, this runner [3] can rotate in described cylindrical hole.This runner [3] axially have an eccentric breach [10] with the eccentric shaft of runner [3], this runner [3] radially have a horizontal cut [2], the left end of described sliding axle [8] is provided with spherical interior projection [5], the radial length of projection [5] makes horizontal cut [2] can hook interior projection [5] and laterally slides greater than the height of horizontal cut [2] in being somebody's turn to do.Should be positioned at eccentric breach [10] by interior projection [5], the radial length (being radial diameter) of the axle journal [6] of projection [5] and sliding axle [8] is slightly less than the height (little 1 millimeter gets final product) of horizontal cut [2] in connecting, make runner [3] when rotating, this axle journal [6] can insert in the horizontal cut [2].Be provided with elastic device between the lower end of described runner [3] and the connecting body [7], accompanying drawing 1 is turriform spring [1], also can be with other elastic devices such as elastic copper sheets, after in the opening slot of the horizontal section bar of connecting body [7] insertion, after runner [3] is located perforate, fixedly connected connecting body [7] in the surface that section bar can be ejected in the upper end portion of runner [3] with horizontal section bar.The upper-end surface of described runner [3] has translot [4], is convenient to insert in this translot [4] rotating wheel [3] with screw-driver.Shown in accompanying drawing 2 and accompanying drawing 3, when turning clockwise, the horizontal cut [2] between the deflection claw hook [11] enters axle journal [6], hooks interior projection [5] and slides left at runner [3], drives whole sliding axle [8] and also slides left.Two end faces of described connecting body [7] are square.Can match with the opening slot inner chamber of horizontal section bar, be unlikely to again in inner chamber, to slide.The diameter of described eccentric breach [10] is greater than the radial length of interior projection [5], and eccentric breach [10] formed breach greater than interior projection [5] at the sidepiece of runner [3], and projection [5] can be entered in the described eccentric breach [10] by this breach in making; When runner [3] rotation one angle, then axle journal [6] inserts in the horizontal cut [2], and horizontal cut [2] claw hook of both sides [11] up and down hooks interior projection [5], and sliding axle [8] can not be slided to the right.See shown in the accompanying drawing 1 that axial circular hole [12] the inwall right part of described connecting body [7] is provided with hook [13] in the wall body, hook [13] is hooked in the radial protrusion place of sliding axle [8] in this wall body, can stop sliding axle [8] to slip away and connect these [7] when not use.
