Description

A kind of automatic close-type handrail door hinge and manufacture method thereof
Technical field
The invention belongs to the attachment means of steel structure platform fence gate, particularly to a kind of automatic close-type railing Door hinge and manufacture method thereof.
Background technology
In recent years, being applied to that steel structure platform is more was civilian, industrial building, and steel structure platform typically uses Steel pipe railing is as the enclosing of steel platform, but under or technological requirement special artificial at some, railing needs Being turned on and off of variable interval, it is necessary to arrange handrail door on railing, general handrail door uses ready-made hinge Formula hinge, it is easy to make is widely used, but it exists dangerous and inconvenient, and door needs after opening Manually closing the door, if forgetting that door opens, certain potential safety hazard can be caused.
Summary of the invention
Having problems in prior art, the present invention provides a kind of automatic close-type handrail door hinge, this conjunction Page increases handrail door safety coefficient effectively, it is ensured that construction personal safety, provides strong guarantee for safety in production.
In order to solve to exist in prior art technical problem, the present invention adopts the following technical scheme that and is practiced: A kind of automatic close-type handrail door hinge, including rotating shaft, upper hinge, lower jaw, described upper hinge and lower conjunction Page is respectively provided with and is in described rotating shaft, the first body that described upper hinge is docked by inclined-plane and the second body structure Becoming, the 3rd body and the 4th body that described lower jaw is docked by vertical plane are constituted, and described first body end leads to Crossing steady pin to be connected with described rotating shaft, described 4th body bottom is connected with described rotating shaft by elastomeric element.
Described upper hinge and described lower jaw are respectively arranged with connecting plate.
Described first body and described second body inclined-plane gradient are 45 DEG C.
Described upper hinge length is equal with lower jaw length.
In order to solve to exist in prior art technical problem, the present invention can also adopt the following technical scheme that and give Implement:
Step one, intercepts the steel pipe that one section of internal diameter is 12mm and therefrom cuts into the first isometric body and by 45 degree Two bodys, then after described first body and described second body are inserted in rotating shaft one end, with steady pin by described First body welds with described rotating shaft, and described first body docks the upper hinge of composition with described second body inclined-plane;
Step 2, intercepts that steel pipe that one section of internal diameter is 12mm is the most crosscutting is slit into the 3rd isometric body and the 4th body, After more described 3rd body and described 4th body being inserted in rotating shaft one end, elastomeric element one end is withstood described 4th body, its other end welds with rotating shaft, and described 3rd body docks composition with described 4th body vertical plane Lower jaw;
Step 3, respectively at described first body, described second body, described 3rd body and described 4th body On be welded to connect plate;
Step 4, then the connecting plate on described first body, described 3rd body is welded with handrail door, will simultaneously Connecting plate on described second body, described 4th body welds with railing.
The method have the benefit that
First invention is 45 degree of contact of incline plane by the first body in upper hinge and the second body, it is ensured that handrail door depends on Accurate return after rotating by inclined-plane, coordinates lower jaw when vertical relative movement simultaneously, and ` is on handrail door In the case of Shenging, gravity can be relied on so that handrail door is closed rapidly, it is ensured that construction safety.
Upper hinge is welded with rotating shaft, by elastomeric element by lower jaw and rotating shaft by second, the present invention by steady pin Welding, both can ensure that handrail door was automatically switched off, can ensure that again the integrity of steel structure platform guardrail.
3rd, present configuration is reasonable, it is ingenious, simple to operate, with low cost to design, and is suitable for popularization and application.
Accompanying drawing explanation
Fig. 1 is one automatic close-type handrail door hinge structure schematic diagram of the present invention.
Fig. 2 is that one automatic close-type handrail door hinge of the present invention uses state diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in further details:
As it is shown in figure 1, the present invention provides a kind of automatic close-type handrail door hinge, including rotating shaft 1, upper hinge 11, Lower jaw 12, described upper hinge 11 and lower jaw 12 be respectively provided with and be in described rotating shaft 1, described upper conjunction The first body 11a and the second body 11b that page 11 is docked by inclined-plane are constituted, described first body 11a and institute Stating the second body 11b inclined-plane gradient is 45 DEG C.The 3rd body 12a that described lower jaw 12 is docked by vertical plane Constituting with the 4th body 12b, described first body end 11a portion is connected with described rotating shaft 1 by steady pin 13, Described 4th body bottom 12b is connected with described rotating shaft 1 by elastomeric element 14.Described upper hinge 11 is long Spend equal with lower jaw 12 length.Described upper hinge 11 is respectively arranged with connecting plate 15 with lower jaw 12.This In invention, in the first body 11a, the second body 11b, the 3rd body 12a and the 4th body 12b all use Footpath is that the steel pipe of 12mm is cut into isometric body.The steady pin 13 of the present invention uses internal diameter to be 10mm round steel, End cap is welded on it.The elastomeric element 14 of the present invention can use steel spring or rubber spring.The present invention connects Fishplate bar 15 uses 4mm~10mm steel plate to carry out cutting and forms.
It is practiced as in figure 2 it is shown, the present invention can also adopt the following technical scheme that:
Step one, intercepts the steel pipe that one section of internal diameter is 12mm and therefrom cuts into the first isometric body 11a by 45 degree With the second body 11b, then after the first body 11a and the second body 11b is inserted in rotating shaft 1 one end, with fixing First body 11a is welded by pin 13 with rotating shaft 1, and described first body 11a is oblique with described second body 11b Face docking constitutes upper hinge 11;
