Description
Technical Field
The invention relates to the technical field of stair locking doors, in particular to an installation method of a stair locking door.
Background
The stairs are public or emergency facilities, cannot be directly locked by a traditional key lock, are inconvenient to directly lock and have great potential safety hazards, and people are not practical to be provided with keys and are unfixed when people go to and go from public places. The door is not locked, so that potential safety hazards are caused, and the stair opening is disordered and not attractive.
Disclosure of Invention
In order to solve the technical problems, the invention provides the installation method of the stair locking door, which can improve the phenomenon that the stair door cannot be automatically closed and is not fixed after being closed, avoid the complexity of the traditional key lock, increase the safety coefficient of field installation, reduce the cost and prolong the service life of the door.
The invention discloses an installation method of a stair locking door, which comprises the following steps:
s1, welding a rotary shaft sleeve on the left side of the stair railing;
s2, enabling the rotating shaft to penetrate through the rotating shaft sleeve, welding the rotating shaft on the left side of the stair gate, and connecting the stair gate and the stair railing together;
s3, cutting the reinforcing steel bars to be 150mm, polishing two ends of the reinforcing steel bars to be smooth to be used as door noses, and welding the door noses on the right side of the stair door;
s4, bending a flat iron with the width of 20mm into an iron ring to be used as a door lock;
s5, bending the steel bar into a U-shaped ring, sleeving the door lock on the U-shaped ring, and welding the U-shaped ring on the right side of the stair railing;
and S6, connecting the stair door with the stair railing through a spring.
According to the installation method of the stair locking door, the door nose used in S3 is a steel bar with the diameter of 6 mm.
According to the installation method of the stair locking door, the door lock used in S4 is an iron ring with the diameter of 80 mm.
According to the mounting method of the stair locking door, hanging rings are arranged at two ends of a spring used in S5, spring hooks are arranged on the lower portion of the rotating shaft and the stair door, and the two groups of hanging rings are hung on the two spring hooks respectively.
Compared with the prior art, the invention has the beneficial effects that: the stair door can be automatically closed and locked by spring tension after being opened, and the door lock is lifted upwards when the stair door is opened when the stair door is higher than a door nose; after the door is closed, the door nose reaches the door lock iron ring, the iron ring is automatically lifted, the door is automatically locked, the ladder door can be provided with different opening directions according to the field environment, when the opening directions are different, the welding and the fixing positions are exchanged, when the stair door is installed according to the installation method provided by the invention, the installation of the stair door lock can protect the door from being opened and closed under the influence of the environment and the like, the phenomenon that the stair door cannot be automatically closed and is not fixed after being closed is improved, the complexity of the traditional key lock is reduced, the safety factor of field production is increased, the cost is reduced, and the service life of the door is prolonged.

Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
As shown in fig. 1 to 2, the method for installing a stair locking door of the present invention comprises the following steps:
s1, welding a rotary shaft sleeve on the left side of the stair railing 2;
s2, enabling the rotating shaft to penetrate through the rotating shaft sleeve, welding the rotating shaft on the left side of the stair door 1, and connecting the stair door 1 and the stair railing 2 together;
s3, cutting a steel bar with the diameter of 6mm by 150mm, polishing two ends of the steel bar smoothly to be used as a door nose 3, and welding the door nose 3 on the right side of the stair door 1;
s4, bending a flat iron with the width of 20mm into an iron ring with the diameter of 80mm to serve as the door lock 4;
s5, bending the steel bar into a U-shaped ring, wherein the U-shaped ring is made of 6mm steel bars and has the same length as the door nose 3, sleeving the door lock 4 on the U-shaped ring, welding the U-shaped ring on the right side of the stair railing 2, and enabling the iron ring of the door lock 4 to freely move up and down;
s6, connecting the stair gate with the stair railing through a spring 5, wherein hanging rings are arranged at two ends of the spring, spring hooks are arranged on the lower portion of the rotating shaft and the stair gate, and the two groups of hanging rings are hung on the two spring hooks respectively.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
