Abstract

The utility model discloses a lacing ring comprising a ring with a gap and two collets throughout the bolts at both sides of the gap, characterized in that an inner hole of the ring is provided with a step. The lacing ring increases the locking force, enhances safety and prevents dust from entering into the clearance between an outer tube and an inner tube.

Description

A kind of bunching ring

Technical field

The utility model relates to a kind of bunching ring of the pipe fitting banding with two phase intussusceptions.

Background technique

A pipe inserts another Guan Zhongxiang intussusception, has both needed to adjust the degree of depth of insertion, and two pipe mutual alignments are fixed.For example the vehicle seat standpipe of bicycle inserts in the seat tube.These class two pipe box stack structures generally all tightly make it fixing with bunching ring with two pipe collars.As shown in Figure 1, existing bunching ring is an annulus that has breach, but respectively there is the chuck of a through bolt on the breach both sides, and an end of bolt is equipped with the Camlock handle.Bunching ring dependence compresses outer tube makes its deformation come pipe in the banding, thereby realizes folded the fixing of two pipe boxes.

But existing bunching ring just makes its generation deformation manage in the banding by compressing outer tube, if the chucking power of the internal pipe of outer tube is big inadequately, interior pipe still can move or rotate relative to outer tube, and in addition, the gap between interior pipe and outer tube also enters dust easily.

The model utility content

The purpose of this utility model is to provide a kind of clamping outer tube simultaneously and interior pipe, and can prevent that dust from entering the bunching ring in gap between outer tube and interior pipe.

A kind of bunching ring described in the utility model an annulus that has breach is arranged, but respectively there is the chuck of a through bolt on the breach both sides, it is characterized in that: there is step at annulus endoporus place.

Bunching ring described in the utility model, when locking two pipe box stack structures, not only rely on and tighten outer tube and make its deformation come pipe in the banding, and the step at annulus endoporus place compresses interior pipe simultaneously, therefore increase the coupling mechanism force of bunching ring, improved Security, and, the step of port has covered the gap between outer tube and the interior pipe, can prevent that dust from entering in the gap.The chuck of described bunching ring becomes one section continuous slur with the handle external form, both reduced windage when riding, and is aesthetic in appearance again, and increased Security, avoids wounding.

Embodiment

A kind of bunching ring described in the utility model, as Fig. 2, Fig. 3, shown in Figure 4, an annulus 1 that has breach is arranged, but respectively there is the chuck 5 of a through bolt 2 on the breach both sides, one end of bolt 2 is equipped with Camlock handle 3, handle 3 is complementary with the curvature of annulus 1, and handle 3 becomes one section continuous slur with chuck 5 external forms again, and there is step 4 at annulus 1 endoporus place.In order to prevent that bunching ring from rotating relative to outer tube 9, on annulus 1, have screw 6 radially, can screw in bolt 7 in the screw to limit the relative position of bunching ring and outer tube 9.

Move the Camlock handle 3 on the bolt 2 for convenience, the local thickening in the outer end of the handle 3 of a kind of bunching ring described in the utility model makes its end abundant and slick and sly, is easy to stir with hand, and for alleviating the weight of thickened portion, thickened portion is a hollow 8.

For cutting down finished cost, the utility model is machined to required size after adopting first extrusion modling.

Claims
