As shown in Fig. 2 and 5, angle connecting portion 6 also comprises connector 16, and it extends and leave lateral support 4 and enter hollow bulb 14 as extension 17.For example, connector 16 is configured to have the bluff body of parallelepiped shape, between two supporting legs of the U-shaped section of lateral support 4, extend, for example, be fixed on this place by suitable parts (rivet 48,49), and be held in this way to make the major part extension of connector 16 to leave lateral support 4.As shown in Figures 4 and 5, connector 16 has straight narrow side or narrow limit 18 and be arranged in parallel with it at a certain distance another narrow side or narrow limit 19.Side 18 is continuous, and side 19 is had groove 20 interruptions of semicircular edge 21.As shown in Figure 6, connector 16 is narrower than lateral support 4.
The cross section of connector 16 is less than the cross section of hollow bulb 14 as shown in figure 10 basically.Fastener 22 is for engaging, and described fastener, as sept 23, can see more clearly from Fig. 4,7 and 8.Sept 23 is plastic bodies, and its exterior contour had makes described plastic body to insert hollow bulb 14 with minimum gap.In order to hold connector 16 or extension 17, described hollow bulb has the recess 24 that cross section is rectangle substantially, and the cross section of described recess is roughly corresponding to the cross section of connector 16, still preferred than the large small tolerance of the cross section of connector.
Sept 23 preferably is configured to the symmetry about vertical plane E, and consists of one piece material.But described sept can also be separated along vertical median plane E, is thus two and half shells.
Fastener narrow side at an upper portion thereof has fillet 25.At its downside, relatively thick and heavy pressure piece 26 forms the terminal of sept 23.Band 25 and pressure piece 26 by flat, parallel, preferably slightly resilient sidewall 29,30 is connected to each other, and defines recess 24 between them.
In the side towards lateral support 4, sept 23 can have braking lug 32,33, for fastener 22 being remained on to connector 16 places.As shown in Figure 2, braking lug 32,33 can arrive the rear portion of connector 16, thus sept 23 or fastener 22 is fastened on lateral support 4.
The jockey that represents angle connection 6 also comprises tensioning apparatus 134, and it preferably includes the expansion gear of for example expanding sleeve 34 forms, and this also has in Figure 12,13 and 19 and illustrate respectively at Fig. 4.Expansion sleeve 34 is by hole 35,36 sidewall 10,11 of packing into, and described hole is aligned with each other, and also with passage 31, aims under confined state.The axial length of expansion sleeve 34 at least reaches the mensuration thickness of axostylus axostyle 3 between the outside flat sides of sidewall 10,11, and still, preferably just over this length, this can clearly find out from Fig. 3 and 18.Preferably, expansion sleeve 34 consists of the plastic material of slightly flexible or extensibility.Preferably, it has the form of closed-loop.Alternately, this expansion sleeve can cut more at least going up fully of its circumference, or cuts on section axial length, in this case, also can consist of the plastic material of less extensibility.Preferably, described expansion sleeve limits a cylinder opening 37, and for holding expansion element 38, this expansion element is for example the bolt made of metal or other materials or the form of cylinder 39.
The size relationship of each element of angle connection 6 especially can be known and see from Figure 11 to 18.Figure 11 shows lateral support 4, and its connector 16 has been inserted into the hollow bulb 14 of axostylus axostyle 3 together with fastener 22 or sept 23.Like this, passage 31 is aimed at hole 35,36.Sept 23 forms certain vertical space V.The vertical height X of this vertical distance Y by band 12,13 and sept 23 produces.The diameter in the diameter B of passage 31 and hole 35,36 is complementary.The outer dia Da of expansion sleeve 34 is less than diameter B, as shown in figure 12.Thus, inside diameter Di is less than the outer dia A (Figure 15-16) of preferred cylindrical dilatation element 38.As shown in figure 14, between expansion sleeve 34 and passage 31 or have space S between hole 35,36, the size in described space is half of difference of diameter B and diameter Da.The poor A of diameter between the inside diameter Di of the diameter of expansion member 38 and expansion sleeve 34 subtracts Di and is preferably greater than vertical space V.
The formation of angle connection 6 is as described below:
At first, separately in Fig. 7 and 8, illustrated sept 23 is snapped on the extension 17 shown in Fig. 5 or connector 16.Then, insert the hollow bulb 14 of axostylus axostyle 3 as shown in Figures 9 and 10 with the lateral support 4 of sept 23.Like this, just can obtain the structure shown in Figure 11.Then, expansion sleeve 34 inserts passage 31, as shown in figure 14.In order to overcome space S, and eliminate vertical space V, now expansion member 38 is pushed into opening 37, reaches thus the state shown in Figure 17 and 18.By strong being radially expanded of expansion sleeve 34, pressure piece 26 moves away connector 16.As a result, vertically highly greatly the increasing of fastener 22, so its upper strap portion 25 and pressure piece 26 are away from each other.
Due to the vertical expansion of fastener 22, vertically space V is overcome, and fastener 22 is sandwiched in the appropriate location in hollow bulb 14.Due to expansion, i.e. the expansion of fastener 22 produces vertical chucking power between band 12 and 13.In this state, angle connection 6 is firmly.There is firm being rigidly connected between lateral support 4 and axostylus axostyle 3.This is equally applicable to other angles and connects 7,8,9.
Figure 19-21 means the function of tensioning apparatus 134, expands sleeve 34 because the effect of expansion member 38 is expanded.When expansion member 38 is driven into narrower opening 37 when interior, produce radially outer power and distribute.When cylindrical dilatation element 38 can be conducive to described driving when at least one side is provided with suitable inclined-plane 40.
Figure 23 means alternative tensioning apparatus 134.As shown in the figure, expansion sleeve 34 can have the biconial passage, and it comprises suitable conical die product 41,42.Moulded parts 41 can have screwed hole, and moulded parts 42 has the recess of the head 43 for holding bolt.By tighting a bolt, two moulded parts 41,42 are pushed together, make thus to expand sleeve 34 and are radially expanded.
Consider another alternative tensioning apparatus 134, expansion sleeve 34 can also be configured to shown in Figure 24 and 25 like that.In this case, expansion sleeve 34 is not circular, and for example it is with corner, fillet.Correspondingly, what passage 31 and hole 35,36 neither be circular, and there is opening shape.The passage 31 of this expansion sleeve 34 can not be circular, that is, be for example oval-shaped.The elliptical modes product correspondingly is placed in wherein, as expansion member 38.If use suitable instrument to rotate, expansion sleeve 34 at least expands at vertical direction, again carries out thus tensioning process mentioned above.
The angle of heald rod 1 connects 6 provides mechanicalness to stablize and being connected of electric insulation between lateral support 4 and axostylus axostyle 3, and described axostylus axostyle is optionally made by another material or metal.Fastener 22 is set connection is provided, this fastener is positioned on the connector 16 of lateral support 4, and inserts the hollow bulb 14 of axostylus axostyle 3 together with described connector.
Figure 26 and 27 means the cross-sectional view according to the jockey shown in Figure 14 and 17 again.Clearly, expansion sleeve 34 shows certain elasticity.It is because expansion member 38 is radially expanded, and therefore, particularly the part between sidewall 10,11 is being radially expanded, and makes connector 16 and pressure piece 26 against band 12,13 diametrically away from each other and tensioning.
Figure 28-30 means to revise and the special embodiment simplified.In this case, tensioning apparatus 134 has towards the tapered main body 50 of a side, for example tapered.Two end face 51,52 is of different sizes.Main body 50 can have the cross section of circular cross section, rectangular cross section or other shapes.Like this, main body 50 can show as taper or prismatic.Preferably, it is made by least having minimum flexible material, for example plastic material.It can be made by one or more pieces materials, and consists of same material.Alternately, it can consist of multiple material.For example, it can have and is provided with the metal-cored of plastic sheath.
In this embodiment, as shown in figure 28, passage 31 is tapers.In median plane M, the diameter D of tapered channel 31 and diameter and the size of end face 41 are complementary.
When main body 50 is pushed into passage 31, as shown in figure 29, described main body is ordered about connector 16 and is separated with pressure piece 26.By making main body 50 strains, it is abundant that described main body is pressed into passage 31 as shown in figure 30, makes its end face 51,51 all outstanding over corresponding sidewall 10,11 a little.Like this, main body 50 tensioning pressure parts 26 and connector 16 make it away from each other, promote described two parts against band 12,13 thus.
