Description
Technical field
The present invention relates to the assembling fittings that tubing connects, relate in particular to a kind of swivel assembly and guardrail that is used for guardrail.
Background technique
Guardrail is that a kind of common tubing connects product, is made up of crossbeam and cylindrical vertical tube as the one of which, and wherein, the crossbeam of many levels is separation up and down, and many vertical tubes vertically are plugged in the crossbeam at the interval, and are connected to form holistic guardrail with crossbeam.
Guardrail is in the middle of practical application; The function that need possess Unscrew usually, for example, by a kind of guardrail of forming by standing part and active part; Its standing part installs and fixes; Active part is connected with standing part through hinge, and active part can rotate with respect to standing part under the effect of hinge, thus the function that realization opens or closes.The standing part of this kind guardrail and active part are independent overall structure, and wherein, standing part connects into an integral body that has frame by fixed beam and fixed tube; Active part connects into an integral body that has frame by walking beam and adjustable pipe; Be connected through the hinge both frame, this has caused the joint of guardrail standing part and active part must have two frames to be set up in parallel, and causes the frame consumable quantity to increase; Improve cost of production, also increased the difficulty of making; Only depend on hinge to link to each other with standing part behind the active part Unscrew and load-bearing, the deadweight of active part causes the hinge distortion easily, damages the shearing force of hinge, causes guardrail can not close or close problems such as not in place.In addition, adopt hinge to connect standing part and active part, its inconvenient installation, the bulk strength that the back guardrail is installed is not high, and the Security of guardrail and working life are also lower.
Summary of the invention
The technical problem that the present invention will solve is the deficiency that overcomes existing technology, provide a kind of simple in structure, with low cost, quick and easy for installation, join strength is high, long service life, can make the two-sided guardrail of opening of guardrail with swivel assembly and guardrail.
For solving the problems of the technologies described above, the present invention adopts following technological scheme:
A kind of guardrail is used the swivel assembly, comprises that with a fixed tube in the guardrail be central shaft first link and second link in relative rotation, and said first link and second link are equipped with the crossbeam joint.
As further improvement of the present invention:
Said crossbeam joint is provided with a hole that is rotationally connected with the fixed tube socket.
Said first link and second link are equipped with the jack of pegging graft and cooperating with crossbeam.
Be provided with between said first link and second link and be used to limit the limit assembly that both relatively rotate angle.
Said limit assembly comprises the protruding limited part of being located on first link.
A kind of guardrail comprises fixed tube, first active part and second active part, and said first active part links to each other with fixed tube through above-mentioned swivel assembly with crossbeam in second active part.
Compared with prior art, the invention has the advantages that:
Guardrail of the present invention is used the swivel assembly, can be connected the crossbeam of two active parts in the guardrail with second link through first link, and crossbeam can be rotated around fixed tube; When two active parts of assembling guardrail; Can use a plurality of swivel assemblies of the present invention that the crossbeam of two active parts of guardrail is connected with fixed tube, can make two active parts of guardrail be connected to form an integral body, not need the frame that hinge is set in addition again and is used to install hinge; Reduced the consumable quantity of guardrail; Reduced cost, the guardrail bulk strength that adopts this swivel assembly to connect is high, and anti-shear ability is strong; Working life and Security also are improved greatly, and quick and easy for installation; Simultaneously, two active parts that connect through swivel assembly of the present invention all can rotate around fixed tube, make the form of guardrail more flexible, can select to open any one active part as required during use, and adaptive capacity is stronger.Limit assembly can limit the angle that relatively rotates of first link and second link, thereby can rationally control the unlatching slewing area of guardrail; Protruding limited part only is set on a link can realizes that corner is spacing, it is simple in structure, and is easy to make; When two links are equipped with protruding limited part, be convenient to make two links to form the complementary structure of mutual overlap joint, make two links be positioned at same level height, thereby improve the aesthetic property of guardrail.Guardrail of the present invention comprises fixed tube, first active part and second active part; First active part is connected with fixed tube through above-mentioned swivel assembly with second active part; Both all can or be closed around the fixed tube Unscrew; This guardrail uses convenient, reliable, and adaptive capacity is stronger.
