The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
As shown in Figure 1, be a kind of embodiment guard bar structure of the utility model sketch map, this guardrail comprises cross bar 1, pipe joint arrangement 2 and montant 3, is connected through pipe joint arrangement 2 between cross bar 1 and the montant 3.Shown in Fig. 2-4; Be a kind of embodiment pipe joint arrangement structural representation; This pipe joint arrangement 2 comprises first end 21 and second end 22, and its first end 21 is used for being connected with cross bar 1, and second end, 22 end faces are cambered surface; Its second end, 22 end faces are provided with a connecting hole 24, are connected with montant 3 through this connecting hole 24.Connecting hole 24 can go deep into second end, 22 an ends part, also can be through to first end, 21 end faces.Pipe joint arrangement 2 is connected with montant 3 through the connecting hole 24 on its end face; It is reliable to make guardrail connect; Easy for installation, the arc shape and the montant of union closely cooperate, and have played the fixing and anti-effect of reversing; Can stop the fixing back of union and guardrail pipe to be rotated, also make the guardrail outward appearance have aesthetic feeling.
Pipe joint arrangement first end 21 of present embodiment is used for being connected with cross bar 1, can take various suitable connected modes.Preferably, the external diameter of first end 21 is equal to or less than the internal diameter of cross bar 1, thereby can realize that first end 21 plugs with cross bar 1.More preferably, the sidewall of first end 21 is provided with fixing hole 23, through this fixing hole 23 21 riveted joints of first end perhaps is screwed on the cross bar 1, thereby the end 21 of winning is connected firmly with cross bar 1.The number of fixing hole 23 can be set as required, for example 2,4,6,8.Fixing hole 23 can be evenly distributed also and can be provided with as required.Be connected with first end 21 for the ease of punching on cross bar 1, preferably, on the sidewall of second end 22, be provided with static line, the fixing hole 23 of this static line and first end is positioned on the same horizon.Preferably, the number of fixing hole 23 is consistent with the quantity of static line.When first end 21 of pipe joint arrangement 2 inserted in the cross bars 1, the side of second end 22 and cross bar 1 connected because fixing hole 23 and static line be horizontally disposed with, thereby be easy to get on the cross bar 1 with first end, 21 sidewalls on fixing hole 23 corresponding holes.In order to reach purpose attractive in appearance, the static line on second end 22 is consistent with the line of rabbet joint on the cross bar 1, and is connected mutually with the line of rabbet joint.
For arc shape and the montant of realizing pipe joint arrangement second end closely cooperates, second end, 22 end faces are inner concave arc surface, block through the outer wall of this inner concave arc surface with montant 3, have played the fixing and anti-effect of reversing, and can stop the fixing back of union and montant to be rotated.Preferably, second end, 22 end faces contact with montant 3, and second end, 22 end faces and montant 3 are complementary.When second end, 22 end faces were inner concave arc surface, its cambered surface external diameter was identical with the external diameter of montant 3, made both closely cooperate.
The installation process of this guardrail is following: the cross bar 1 and montant 3 that install guardrail; When connecting cross bar 1 with montant 3; First end 21 of this pipe joint arrangement 2 is inserted in the hole of cross bar 1; Static line according to horizontal direction on second end, 22 sidewalls punches on cross bar 1, utilizes the connected mode that is spirally connected or rivets through this hole, thereby cross bar 1 is fixedly connected with first end 21.Utilize fixed bar that second end 22 of montant 3 with pipe joint arrangement 2 fixed then.Fixed bar can be taked various suitable connecting rods, is preferably bolt.According to the length of connecting bolt, can pass second end 22 that arrives pipe joint arrangement 2 from the outer wall or the inwall of montant 3.If bolt is longer, can the nut of bolt be stayed on the outside wall surface of montant 3, pass second end 22 of arrival pipe joint arrangement 2 from the outer wall of montant 3; If bolt is shorter, can the nut of bolt be stayed on the internal face of montant 3, pass second end 22 of arrival pipe joint arrangement 2 from the inwall of montant 3.The adjacent crossbars of the guardrail that the utility model is mounted to and the radian scope between the cross bar can be between 90 °～135 °, and pipe joint arrangement 2 can adopt aluminium casting or other metal casting form.
The utility model also provides a kind of pipe joint arrangement; This pipe joint arrangement is used to connect first object and second object, and shown in Fig. 2-4, this pipe joint arrangement comprises first end 21 and second end 22; Its first end 21 is used for being connected with first object; Second end, 22 end faces are cambered surface, and its second end, 22 end faces are provided with a connecting hole 24, are connected with second object through this connecting hole 24.Preferably, the sidewall of first end 21 is provided with fixing hole 23.More preferably, the sidewall of second end 22 is provided with static line, and the fixing hole 23 on the static line and first end 21 is positioned on the same horizon.This pipe joint arrangement is connected with second object through the connecting hole 24 on its end face, and it is more reliable to make that this pipe joint arrangement connects
In order to realize closely cooperating of second end 22 and second object, the second end end face is an inner concave arc surface.Easy to connect for second end 22 and second object, connecting hole 24 is through to first end, 21 end faces from the second end end face.In order to connect the first different object of internal diameter and second object, when the second object internal diameter during greater than first object, preferably, the external diameter of second end 22 is greater than the external diameter of first end 21.
Can find out by above embodiment; The utility model embodiment is connected with montant through connecting hole is set on the end face of pipe joint arrangement, and it is reliable, easy for installation to make guardrail connect; The arc shape and the montant of union closely cooperate; Play the fixing and anti-effect of reversing, can stop the fixing back of union and guardrail pipe to be rotated, also made the guardrail outward appearance have aesthetic feeling.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and replacement, these improvement and replacement also should be regarded as the protection domain of the utility model.
