Abstract
The utility model discloses a connecting elbow in a guardrail connection structure, comprising a straight joint and a bent joint, wherein the straight joint and the bent joint are connected in an articulated mode; a first joint arm is formed at one end of the straight joint, and a muzzle bell is formed at the other end; a second joint arm is formed at one end of the bent joint, and a muzzle bell is formed at the other end; and a concave part is formed on the first joint arm or the second joint arm, and a convex part articulated with the concave part is formed on the other joint arm. The connecting elbow is widely used in various places of corners of guide rails of staircases, especially places where a guide rail of a staircase has a 180 turn and an upper face pipe and a lower face pipe have height difference.
Description
Technical field
The utility model relates to guard bar technique field, the connecting bend in a kind of guardrail syndeton of more specifically saying so.
Background technology
Guardrail we the life in everywhere as seen, on the building stair, do handrail or protection, and that our the daily facial canal of seeing in a lot of stair railings adopts is wooden more, the stair railing corner is more, the convenient splicing of wooden facial canal is turned round, especially turn through 180 degree and when there is height in facial canal up and down relating to, the facial canal of metal pipe material with regard to difficult to accomplish, prior art is finished at a plurality of kinkings of this local general employing, and between the kinking or be simple snapping, just directly welding is dead, and technology is in the very backward situation.
Also the someone adopts universal joint to solve problem at present, as the disclosed a kind of safety barrier universal joint of Chinese patent CN200820162322.6, be used for each railing is connected into the used union of whole guardrail, comprise fittings body, the integral body that described fittings body is connected into by left and right joint arm and plinth, the forward and reverse rotation of described left and right joint arm solderless wrapped connection headstock, the supporting guardrail that is assembled into of this universal joint and railing uses, but any direction rotates the direction that left and right joint arm changes universal joint as required.Yet universal joints structure is relatively very complicated, and in the guardrail field in case to install be exactly the structure of a typing, the somewhat underemployed here meaning of universal joint has increased cost to guardrail, also makes structure complicated.
The utility model content
The purpose of this utility model is to overcome the deficiency that prior art guardrail joint design complexity, inconvenience are installed, provide a kind of simple in structure, cost is low, simple installation is flexible, the connecting bend in the guardrail syndeton of good looking appearance.
In order to reach above purpose, the utility model is to be achieved through the following technical solutions: the connecting bend in a kind of guardrail syndeton, comprise straight knot and kinking, it is characterized in that, described straight knot adopts articulated manner to be connected with kinking, described straight knot one end forms the first joint arm, the other end forms running-on, described kinking one end forms the second joint arm, the other end forms running-on, on the described first joint arm or the second joint arm, form a recess, the protuberance that formation one and described recess are hinged on another joint arm.This connecting bend adopts straight knot and the hinged cooperation of kinking, both can form the connection of multi-angle, can solve the guardrail facial canal from oblique to the plane excessively, kinking can solve the situation that the guardrail facial canal is turned again simultaneously, adopts two these connecting bends can solve the guardrail facial canal again simultaneously in addition and turns through 180 degree.This connecting bend is widely applicable for the various situations that stair railing turns round, and especially turns through 180 degree and when there is height in facial canal up and down relating to.
As preferably, form a recess in the described first joint arm centre position, the end face of recess forms the arcwall face that caves inward; At the protuberance that formation one of the described second joint arm centre position and described recess are hinged, the end face of protuberance forms the arcwall face to outer lug.The arcwall face that arcwall face that described recess end face forms and described protuberance end face form is suitable.It is more level and smooth that protuberance that is provided with and recess are hinged win joint arm and the second joint arm to realize, and a pair of arcwall face that forms at recess end face and protuberance end face, make the articulated section contact tightr reliable, can also prevent the unexpected situation that crushes the installer in the installation process.
As preferably, form a recess in the described second joint arm centre position, the end face of recess forms the arcwall face that caves inward; At the protuberance that formation one of the described first joint arm centre position and described recess are hinged, the end face of protuberance forms the arcwall face to outer lug.The arcwall face that arcwall face that described recess end face forms and described protuberance end face form is suitable.It is more gentle that protuberance that is provided with and recess are hinged win joint arm and the second joint arm to realize, and a pair of arcwall face that forms at recess end face and protuberance end face, make the articulated section contact tightr reliable, can also prevent to crush in the unexpected installation process installer's situation.
As preferably, on the first joint arm and the second joint arm, form the screw that can pass for bolt respectively, the first joint arm can overlap when both are connected relatively with screw on the second joint arm.Bolt and screw make win joint arm and the second joint arm be hinged more firm, more reliable.
Beneficial effect: this connecting bend adopts straight knot and the hinged cooperation of kinking, both can form the connection of angle many, can solve the guardrail facial canal from oblique to the plane, kinking can solve the situation that the guardrail facial canal is turned again simultaneously, adopts two these connecting bends can solve the guardrail facial canal again simultaneously in addition and turns through 180 degree.
