Detailed description of the invention
As shown in Figure 4, Figure 5, the utility model embodiment provides a kind of subway handrail suspension bracket connecting device, at least comprise vertical suspension rod 2 and threeway 3, one end of vertical suspension rod 2 is stretched in tee branch 3a, the end of vertical suspension rod 1 has at least two flexible protruding heads 4, tee branch 3a inwall has the draw-in groove 5 that quantity is identical with flexible protruding head 4, each flexible protruding head 4 is all arranged in a draw-in groove 5.
The subway handrail suspension bracket connecting device that the utility model provides, during use, tee branch 3a inside is inserted in the one end that vertical suspension rod 2 can be provided with flexible protruding head 4, flexible protruding head 4 is inwardly shunk by the prevention of tee branch 3a inwall, it is inner that vertical suspension rod 2 enters tee branch 3a smoothly, until when stretching into draw-in groove 5 position, suffered by flexible protruding head 4, namely external force come from distress resolves or the reduction of tee branch inwall, flexible protruding head 4 discharges elastic card and is located in draw-in groove 5, thus realize the connection of vertical suspension rod 2 and tee branch 3a, relative to prior art, only need vertical suspension rod 2 to be inserted in the draw-in groove 5 of tee branch 3a inner arm, without the need to aligning and screwing bolts assembly, enormously simplify erection procedure, time saving and energy saving, and this threeway can select common threeway to be original blank, process in its arm draw-in groove 5 just can, lower relative to prior art productive costs.
The telescopic direction of the flexible protruding head 4 in the present embodiment is identical with the depth direction of the draw-in groove 5 be arranged on tee branch 3a inwall, like this, when flexible protruding head 4 just can be shunk under the interception of tee branch 3a inwall, when arriving draw-in groove 5 position, just can extend, and when flexible protruding head 4 is stuck in draw-in groove 5 inside, vertical suspension rod 2 can not move axially relative to tee branch 3a, form the horizontal strong point that suspension bracket is set by draw-in groove 5 with coordinating of flexible protruding head 4, and then suspension bracket is hung society and push up in compartment.
Wherein, the cross-sectional plane of vertical suspension rod 2 and the cross-sectional plane of tee branch 3a all rounded, flexible protruding head 4 is along the radial expansion of vertical suspension rod 2.Vertical suspension rod 2 directly can adopt round steel pipe, and draw materials extensively, cost is lower.
Further, vertical suspension rod 2 is made up of round steel pipe 23 and the solid head 24 be arranged on bottom round steel pipe 23, and solid head 24 inside is provided with at least two radial holes 25, and radial hole 25 is blind hole;
Flexible protruding head 4 comprises protruding head body 41 and spring 42;
Spring 42 is arranged in radial hole 25, and spring 42 one end is fixedly connected with the bottom of radial hole 25, and the other end of spring 42 is fixedly connected with protruding head body 41;
Protruding head body 41 part is positioned at radial hole 25, and another part stretches out outside radial hole 25.Structure is simple, is easy to make, and reliable in action.
In order to ensure that vertical suspension rod 2 is at circumferencial direction stress equalization, flexible protruding head 4 is uniform along the cross-sectional plane of vertical suspension rod 2.
For simplifying fitting operation further, draw-in groove 5 is formed through a closed circular groove each other on tee branch 3a inwall.Like this when vertical suspension rod 2 inserts in tee branch, flexible protruding head 4 aligned in the circumferential with draw-in groove with regard to not needing, circumferential optional position is inserted all flexible protruding heads 4 and can be coordinated with circular groove.
Install for further convenient, protruding head body 41 is in wedge shape, and the tip of the protruding head body 41 vertically near-end that is connected with threeway 3 of suspension rod 2.So when mounted, the tip of protruding head body 41 is easily inserted in tee branch 3a, make it shrink diametrically without the need to manual pressure protruding head body 41 in tee branch 3a inwall, to insert cooperation with it, be more convenient to protruding head body 41 and coordinate with the insertion of tee branch 3a.
As shown in Figure 6, this connecting device also comprises at least two back(ing) bars 1, and back(ing) bar 1 two ends are all inserted in three-way straight pipe 3b; Two back(ing) bars 1, for inserting insertion end 11 grafting each other in the straight tube of threeway, are connected by screw 6 between three-way straight pipe 3b and the insertion end 11 of two back(ing) bars.Screw 6 passes insertion end 11 and the three-way straight pipe 3b tube wall of two back(ing) bars, is fixedly connected with between three, and structure is simple, is connected firmly.
