Technical field
The present invention relates to the assembling fittings that tubing connects, relate in particular to a kind of guardrail swivel assembly and guardrail.
Background technology
Guardrail is that a kind of common tubing connects product, and it is generally comprised of crossbeam and cylindrical vertical tube, and wherein, the crossbeam of many levels is between the upper and lower every layout, and many vertical tubes are vertically plugged in crossbeam at interval, and are connected to form holistic guardrail with crossbeam.
Guardrail is in the middle of practical application, conventionally need possess the function of Unscrew, for example, by a kind of guardrail being formed by standing part and movable part, its standing part is installed fixing, movable part is connected with standing part by hinge, and under the effect of hinge, movable part can rotate with respect to standing part, thereby realizes the function opening or closing.The standing part of this kind of guardrail and movable part are independent overall structure, wherein, standing part connects into the entirety with frame by clamped beam and stationary pipes, movable part connects into the entirety with frame by walking beam and adjustable pipe, be connected through the hinge both frame, this has caused the junction of guardrail standing part and movable part must have two frames to be set up in parallel, and causes frame consumable quantity to increase, improve cost of production, also increased the difficulty of making; After movable part Unscrew, only depend on hinge to be connected with standing part and load-bearing, the deadweight of movable part easily causes hinge distortion, damages the shearing force of hinge, causes guardrail can not close or close the problems such as not in place.In addition, adopt chain connection standing part and movable part, it installs inconvenience, and after installing, the bulk strength of guardrail is not high, and the safety of guardrail and application life are also lower.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, provide a kind of simple in structure, with low cost, quick and easy for installation, bonding strength is high, long service life, guardrail swivel assembly and guardrail that theftproof performance is good.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of guardrail swivel assembly, comprise the first connector rotating near axle centered by the stationary pipes of movable part and the second connector being connected with described stationary pipes in guardrail, described the first connector is provided with the walking beam connecting portion for connecting guardrail walking beam, described the second connector is provided with the clamped beam connecting portion for connecting guardrail clamped beam, between described the first connector and the second connector, is provided with anti-detachment mechanism.
As a further improvement on the present invention:
Described anti-detachment mechanism is the limit assembly that can stop the first connector and the second connector to depart from along the direction perpendicular to clamped beam.
Described limit assembly comprises that two intervals are connected in the clamping plate on the second connector, two clamping plate are respectively equipped with one and are rotationally connected hole, on described at least one clamping plate, along the surrounding that is rotationally connected hole, be provided with a position limiting convex ring with inclination lead-in groove, on described the first connector, along the surrounding that is rotationally connected hole, be provided with and can pack the bulge loop that is rotationally connected position limiting convex ring into from inclination lead-in groove.
Angle between described inclination lead-in groove arranged direction and clamped beam arranged direction is a, 90 ° of 0 °≤a <.
Described the first connector and the second connector are folding hinged by stationary pipes.
Described the first connector is provided with and walking beam the first jack coordinating of pegging graft, and described the second connector is provided with and clamped beam the second jack coordinating of pegging graft.
A kind of guardrail, comprises the walking beam of movable part and the stationary pipes of standing part, clamped beam, and described walking beam is connected with the stationary pipes near movable part by above-mentioned guardrail swivel assembly with clamped beam.
Compared with prior art, the invention has the advantages that:
Guardrail swivel assembly of the present invention can be connected to form an entirety by guardrail rotating part and standing part, and the rotating part of guardrail can be rotated around stationary pipes, do not need to arrange in addition again hinge and for the frame of hinge is installed, reduced the consumable quantity of guardrail, reduced cost, adopted the guardrail bulk strength of this swivel assembly high, anti-shear ability is strong, application life and safety are also improved greatly, and quick and easy for installation; Meanwhile, between the first connector and the second connector, be provided with anti-detachment mechanism, improved theftproof performance and the security performance of guardrail.The present invention can be made as anti-detachment mechanism the limit assembly that can stop the first connector and the second connector vertically to depart from; in the situation that stationary pipes is destroyed; this anti-detachment mechanism can make the first connector and the second connector still keep connection status, forms duplicate protection.Limit assembly is undertaken spacing by the first bulge loop and the cooperation of the second bulge loop, it is simple in structure, easy to make, and inclination lead-in groove has limited the first bulge loop and packed or exit the path of the second bulge loop into, thereby guarantees that the first connector and the second connector can arbitrarily not depart from.The first connector and the second connector are folding hinged, have increased the angular range of movable part rotating opening, and opening rear guardrail movable part can be folding with standing part, occupies little space.Guardrail of the present invention, owing to having adopted above-mentioned guardrail swivel assembly, therefore also has advantages of that this guardrail swivel assembly possesses.
