Summary of the invention

The applicant is at the connector manufacturing cost is higher in the above-mentioned existing spring clamping type fence, the vertical tube punching quality is relatively poor, shortcomings such as the clamping reliability is relatively poor, a kind of simple in structure, easily manufactured, easily assembled clip clamping type fence is provided, thereby reduced the manufacturing cost of connector, improved product reliability and packaging efficiency.

The technical solution adopted in the present invention is as follows:

A kind of clip clamping type fence, horizontal bar and perpendicular hurdle by orthogonal arrangement are formed, carry out clamping by shell fragment, described shell fragment is shaped as " } " shape, its side boss has locating platform and guiding surface, the one-sided perforate in described perpendicular hurdle, and the boss of described shell fragment stretches out from described perforate, the internal face butt on the flanging at shell fragment two ends and perpendicular hurdle, the through hole internal face clamping of the boss of described shell fragment and horizontal bar.It is further characterized in that:

Clip clamping type fence perforate have two at least, the staggered respectively opposite flank that is positioned at perpendicular hurdle;

The horizontal bar through hole aperture of clip clamping type fence is provided with lasso.

The present invention adopts the elastic piece structure of one-sided boss, and is simple in structure, simplified its production mould and technology greatly, reduced the manufacturing cost of connector.By perpendicular hurdle is carried out monolateral punching, effectively reduce the wearing and tearing of drift, increase exponentially die life; Mould can adopt plug that the internal face on perpendicular hurdle is supported simultaneously, has effectively avoided producing big punching press burr and wall depression, has simplified packaging technology simultaneously, has improved product reliability and packaging efficiency greatly.And the internal face butt on the flanging at shell fragment two ends and perpendicular hurdle can bear the whole shell fragment protuberances and the clamping power of horizontal bar perforate by this structure, so good reliability after the clamping, and shell fragment is difficult for getting loose.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.

To shown in Figure 7, the present invention is made up of with perpendicular hurdle 4 horizontal bar 3 of orthogonal arrangement as Fig. 1, perpendicular hurdle 4 side perforates 7, and the boss 12 of shell fragment 10 ejects from hole 7, with the through hole 8 internal face clampings of horizontal bar 3; To shown in Figure 7, shell fragment 10 is for adopting " } of stainless steel band punching out as Fig. 3 " shape, its side boss 12 has locating platform 11 and guiding surface 13, and the internal face on the flanging at its two ends and perpendicular hurdle 4 offsets, and makes shell fragment 10 effective location in perpendicular hurdle 4.The present invention is installed on the fence post 1 by runway shape hole, horizontal bar 3 end 6 and connector 2.

During actual processing and manufacturing, punching out through hole 8 on horizontal bar 3 earlier; Side punching out square hole 7 on perpendicular hurdle 4, the present invention only need be in the one-sided punching on perpendicular hurdle 4, and does not need the two sides is dashed logical, therefore can effectively reduce the wearing and tearing of drift, increases exponentially die life; During the mould punching press, can adopt the plug mould that the internal face on perpendicular hurdle 4 is supported, effectively avoid producing big punching press burr and wall depression.Usually can be on perpendicular hurdle 4 two square holes 7 of punching out upper and lower side, on staggered respectively two opposite flanks that are positioned at perpendicular hurdle 4.For body of wall fence as shown in Figure 1, its perpendicular hurdle 4 heads have a blind end, a shell fragment 10 can be filled in the hollow tube on perpendicular hurdle 4 during installation earlier from openend, its locating platform 11 upwards, from the square hole 7 on top, eject, to erect hurdle 4 then passes from the through hole 8 of top horizontal bar 3-1, because shell fragment 10 side boss 12 have guiding surface 1, therefore shell fragment 10 elastic force shrink during the through hole 8 by top horizontal bar 3-1, passed through smoothly, spacing by internal face by the locating platform 11 of shell fragment 10 with upper back horizontal bar 3-1; Many perpendicular hurdles 4 can be in place with top horizontal bar 3-1 according to the method described above.Pass many perpendicular hurdles 4 with the through hole 8 of bottom horizontal bar 3-2 this moment again, bottom horizontal bar 3-2 is positioned over the medium position on perpendicular hurdle 4 earlier, fill in bottom shell fragment 10 from the openend on perpendicular hurdle 4 then, its locating platform 11 is downward, eject from the square hole 7 of bottom, horizontal bar 3-2 falls with the bottom, and its through hole 8 is by the guiding surface 1 of shell fragment 10 side boss 12,11 on the platform that is positioned is spacing, has promptly finished assembling of the present invention this moment; Also can pass through securing member 5, further fixed fence.Can fence in blocks be installed on the fence post 1 of infield by runway shape hole, horizontal bar 3 end 6 and connector 2 at last.In like manner for balcony formula fence, its perpendicular hurdle 4 both ends opens do not seal, and the mode of then assembling is more flexible, can directly fill in shell fragment 10 from openend.

The present invention has adopted on perpendicular hurdle 4 relative one-sided perforates, and when filling in the shell fragment 10 on top, its boss 12 can not eject from the square hole of bottom; And the top V-arrangement Spring Card of prior art is when filling in the hollow tube on perpendicular hurdle 4, needing earlier needs first employing instrument close the bottom square hole by the both sides square hole of bottom this moment, prevents from that boss from ejecting to block, this technology is comparatively complicated, greatly reduces assembling efficiency.

As shown in Figure 8, can add lasso 9 on through hole 8 apertures of horizontal bar, lasso 9 can adopt the rubber material, both can prevent from that rainwater from infiltrating not carry out the surface-treated internal face, causes corrosion; Simultaneously can reduce fit clearance, make the location between perpendicular hurdle and the horizontal bar more stable.

More than describing is explanation of the invention, is not that institute of the present invention restricted portion is referring to claim to the qualification of invention, and under the situation of spirit of the present invention, the present invention can do any type of modification.
