Embodiment
Below in conjunction with embodiment shown in the drawings, the utility model is further described.
As depicted in figs. 1 and 2, Universal support bar of the present utility model comprises: be positioned at the bent body of rod 1 in middle part and be located at the joint 2 at the described forward and backward two end part of the body of rod 1 respectively.Specialization of the present utility model is: the described bent body of rod 1 is connected in sequence from front to back by multiple plastic fastening.These plastic fastenings comprise: at front connection pieces 11 foremost, at the rear attachment 12 of rear-most end and the multiple middle parts link 13 between described front connection pieces 11 and rear attachment 12.Described plastic fastening can one-body moldedly be made, and manufacturing process is simple and be easy to assembling.
Wherein, as shown in Figure 5, the front portion of described middle part link 13 is provided with the connection-peg 14 that outer surface is spherical calotte, and rear portion is then provided with plug socket 15, and the rear end of described plug socket 15 is provided with the recess 151 that inwall is spherical calotte.As shown in Figure 4, the rear portion of described front connection pieces 11 is provided with the plug socket 15 of band portion sphere inwall equally.As shown in Figure 6, the front portion of described rear attachment 12 is then provided with the connection-peg 14 that outer surface is spherical calotte.As shown in Figures 2 and 3, the connection-peg 14 of a certain plastic fastening inserts in plug socket 15 recess 151 of front adj acent plastic link, recess 151 inwall of plug socket 15 coordinates with connection-peg 14 intimate of rear adj acent plastic link, can relatively rotate between adj acent plastic link thus, the overall body of rod 1 just can be bent to a certain angle by the needs of user.
In order to deviate between adjacent plastic fastening when preventing from exerting oneself excessive, as shown in Figures 2 and 3, Universal support bar of the present utility model is also being provided with one and is getting lines crossed 3.Correspondingly, each described plastic fastening is equipped with axis hole 16, described in get lines crossed 3 through each plastic fastening axis hole 16 and two end part knotting, all plastic fastenings can be serially connected and can not deviate from.
In addition, the recess 151 of described plug socket 15 surrounds most of sphere of described connection-peg 14, the diameter of described recess 151 opening is slightly smaller than the spherical diameter of connection-peg 14, the elasticity of plastic material itself will be utilized firmly to be clamp-oned in the recess 151 of plug socket 15 by connection-peg 14 thus during assembling.The tightness that this structure can connect between reinforced plastic link, prevents from deviating from easily between plastic fastening.
As shown in Figure 2, the joint 2 of the described body of rod 1 end comprises: joint body 21, first intermediate plate 22 and the second intermediate plate 23.Wherein, described joint body 21 is the tubular structure of hollow near one end of the body of rod 1.The semi-circular cylindrical of profile in centrally axle cutting of described first intermediate plate 22 and the second intermediate plate 23, two intermediate plates 22 and 23 connect and merge the end of the described body of rod 1, namely also the front portion of front connection pieces 11 or the rear portion folder of rear attachment 32 are trapped among in the inner chamber that both are encircled into, and two intermediate plates 22 be bonded with each other and 23 are closely socketed in the inner chamber 211 of this joint body 21.
As shown in Figure 4, the outer end of described front connection pieces 11 is fixedly connected with a square 17 by an attachment post 18 and a thinner neck 19, equally, as shown in Figure 6, the outer end of described rear attachment 12 is also installed with a square 17 by an attachment post 18 and a thinner neck 19.
As shown in Figure 7 and Figure 8, the inwall of described first intermediate plate 22 and the second intermediate plate 23 is provided with described square 17 and attachment post 18 position is corresponding, the cavity of form fit 241 and 242.When two intermediate plate 22 and 23 relative bondings are by the end of the body of rod 1, namely when the outer end folder of front connection pieces 11 or rear attachment 12 fences up, described square 17 is embedded in cavity 241, attachment post 18 is embedded in cavity 242, thus can prevent front connection pieces 11 or relatively rotate between rear attachment 12 and joint 2.
As shown in Figure 7 and Figure 8, the mating face of described first intermediate plate 22 is provided with protruding 28, on the mating face of the second intermediate plate 23, corresponding position is then provided with recess 29, this projection 28 and recess 29 male-female engagement when two clip bonded, facilitates the joint between two intermediate plates 22 and 23 to locate.
As shown in Figure 9, described first intermediate plate 22 and the second intermediate plate 23 are circumferentially provided with convex edge 25 on the outer side wall near the described body of rod 1 side, and in addition, the outer side wall of two intermediate plates 22 and 23 is also provided with many exhaust grooves 27 vertically.As shown in Figure 10, described joint body 21 is circumferentially provided with circumferential groove 26 with corresponding part, position, described convex edge 25 on the inwall of the inner chamber 211 of the body of rod 1 side.During assembling, the elasticity hydraulic pressure of plastic material can be utilized or pneumatic shuttle is disposable is squeezed into by two good for the joint of many struts intermediate plates in the inner chamber 211 of multiple joint body 21, until described convex edge 25 embeds in described circumferential groove 26, now, joint body 21 closely can be socketed in outside the body of rod 1 end and two intermediate plates and can not be separated, exhaust groove 27 can discharge the air between joint body 21 and two intermediate plates 22 and 23 in the process, prevents joint body 21 from resetting under the influence of air pressure.The package assembly of above-mentioned joint is with traditional compared with the method for the body of rod 1 end molding and forming joint, and be more easy to assembling, its yield rate is much higher, and consumptive material is less and safer, and cost is also reduced greatly.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
