Description
Technical field
The utility model relates to a kind of connection set, is meant a kind of connection and securing means that is used for two straight-bars or sleeve pipe specifically.
Background technique
When assembling support, shelf or Show stand, often two pole end-to-ends need be fixed, or two sleeve pipes length on demand fixed, the existing fixed method generally is to utilize locating stud or fixing bolt to realize, offers tapped hole or pin-and-hole in the pole end earlier, utilizes bolt or locating stud with two strut fixation then, this mode is installed, demolition is more convenient, but can't change floor height as required flexibly,, the intensity of pole is reduced if a plurality of tapped holes are set.Generally fix between the sleeve pipe, can change floor height as required, but its bearing power is relatively poor, and install also inconvenient by a housing pin.
So need a kind of installation, convenient disassembly, connection simple and reliable for structure and securing means utilize this device can assemble support, shelf or Show stand easily as required.
The model utility content
For solving above-mentioned technical problem, the utility model provides a kind of being connected and securing means of two poles (upper rack posts and lower fulcrum bar) or two sleeve pipes (going up sleeve pipe and casing running) that be used for fixing, and this device comprises that the last collar that cross section is c-shaped and lower collar, two ends are connected to the spring on two collars and are fixed on handle on the collar.The described collar of going up outwards is convexly equipped with a pair of projection along its vertical breach, handle is rotatably mounted to by a clamping bolt on the outer side surface of one of them projection of the collar, the outer side surface of this projection is provided with the fan-shaped boss coaxial with clamping bolt, this fan-shaped boss is level and smooth inclined-plane along its wherein side radially, the handle upper end portion is provided with and the mutually meshing pad of aforementioned fan-shaped boss, this pad is provided with the size fan-shaped bump identical with fan-shaped boss, this fan-shaped bump can slide on the inclined-plane at fan-shaped boss under handle drives, when the fan-shaped bump on the pad rotates to fan-shaped boss top, because the constraint of clamping bolt, can promoting wherein, a projection moves to another projection, breach is diminished, thereby clamp upper rack posts.The outer peripheral surface of last collar lower edge is provided with a pair of cylindrical slider, and two cylindrical sliders are symmetrically set in collar both sides.Described lower collar upper end portion upwards is convexly equipped with a U-shaped chute and the O shape chute that an opening makes progress, and aforesaid two cylindrical sliders are slidedly arranged on respectively in U-shaped chute and the O shape chute.Lower collar outwards is convexly equipped with a pair of projection along its vertical breach, and wherein a projection is provided with tapped hole, and one regulates bolt passes another projection and be screwed onto on this tapped hole rotation adjusting bolt can regulate lower collar breach size.Aforesaid both ends of the spring portion is positioned at the breach of the collar and lower collar and is separately fixed at clamping bolt and regulates on the bolt, and this spring abuts against on the lower collar collar.The handle middle part is provided with a pulley, lower collar is provided with the curve slope that cooperates with this pulley corresponding to the projection upper surface of handle one side, this curve slope reduces gradually along projection bearing of trend height, far away more then low highly more apart from lower collar, handle with sleeve can make pulley move along curve slope, because the distance of pulley and arm pivot post is greater than the distance of arm pivot post to the arcuate surface inner edge, when pulley moves on to the arcuate surface inner edge, can promote the collar moves up, at spring, under U-shaped chute and the acting in conjunction of O shape chute, the axis of the last collar produces skew, and upper rack posts spare lower end is stuck on the collar inwall.
For ease of fitting operation, the endoporus of lower collar is a shoulder hole, and diameter in hole is less than the diameter in following hole on it, and the interior hole size of the last collar is identical with the last bore dia of lower collar.Lower fulcrum bar is set in the following hole of lower collar during installation, and upper rack posts passes the collar and is sheathed in the last hole of lower collar.If sleeve pipe, then casing running is sheathed in the following hole of lower collar, and last casing pipe sleeve is located in the last hole of the collar and lower collar.
Fan-shaped boss on the last collar generally is provided with two, two fan-shaped boss are symmetrically set on the circumferential surface at its place, described pad is provided with and the identical fan-shaped bump of fan-shaped boss size, fan-shaped boss and fan-shaped bump can be meshing mutually, one side of fan-shaped boss and fan-shaped bump is level and smooth inclined-plane, the another side is vertical surface or the sty bigger with the angle of bottom surface, and fan-shaped bump can only be rotated along a direction.Be folded with stage clip between two projections of the last collar, when fan-shaped boss goes to when relative with fan-shaped bump, two bump pitch of the last collar diminish, thereby clamp upper rack posts, and this moment, stage clip was in compressive state; When fan-shaped boss and fan-shaped bump are replied mutual meshing state, the spacing reinstatement under self elastic force and stage clip thrust of two projections of the last collar, spring is reinstatement also.
Working position for fixed handle, this device can not unclamped from tightening state voluntarily, also can establish a screens tip on the lower collar, folder is established a spring between this screens tip and lower collar, the screens tip protrudes in the projection external lateral portion and is wedge shape, and its inclined-plane is towards away from lower collar one side.
Because handle is to be fixed on the collar by clamping bolt, does not rotate with handle for making clamping bolt, this clamping bolt is provided with fixedly projection, and the described projection of going up the collar is provided with the groove that matches with the aforementioned fixation projection.
By above-mentioned description to the utility model structure as can be known, compare with prior art, the utlity model has following beneficial effect: only need rotatable handle during installation, can be with two poles or two sleeve pipes connection and fixing, it is rational in infrastructure, compact, installation, convenient disassembly can be provided with setting height(from bottom) as required flexibly, are specially adapted to set up travel(l)ing rest and Show stand.
