Door control top spring with lighter door opening force and more stable door closing speed
Technical Field
The invention relates to the technical field of door control springs, in particular to a door control roof spring with lighter door opening force and more stable door closing speed.
Background
The door control spring is often used for controlling the opening and closing of the door body, and along with the continuous development of the process technology, in order to enable the anti-theft effect of the door body to be better, the door body is made more and more heavy, and therefore the door control spring is also developed.
Although the traditional door control spring can play a role in supporting the door body, the traditional door control spring cannot play a role in assisting some heavier door bodies, so that people can do more labor when opening the door body, therefore, the traditional door control spring only plays a role in relieving when the heavier door bodies are closed, and the door body has larger inertia when closed, so that the closing speed of the door body is not stable; in addition, the inside of the existing door control spring needs to be oiled and lubricated after being used for a period of time, the oiling needs to be manually operated at regular intervals, and if people forget the operation, the service life of the door control spring is shortened, so that the door control spring with lighter opening force and more stable closing speed is produced.
Disclosure of Invention
In order to achieve the purposes of light door opening force, more stable door closing speed and self-lubrication, the invention provides the following technical scheme: the power of opening the door is lighter and the gate day spring that closes door speed more steady, including the casing, its characterized in that: the surface swing joint of casing has the connecting piece, the inside fixedly connected with pinion rack of casing, and the surface swing joint of pinion rack has the harmomegathus wheel, and one side swing joint that the pinion rack was kept away from to the harmomegathus wheel has the stripper plate, and one side swing joint that the harmomegathus wheel was kept away from to the stripper plate has compression spring, the inside swing joint of harmomegathus wheel has the spring beam, and the surface swing joint of spring beam has the liquid storage ring, and the fixed surface of liquid storage ring is connected with the osmotic membrane, and the fixed surface of harmomegathus wheel is connected with.

1. by placing the shell at the opening and closing connection part of the door body, when the door body is in an opening state, the collapsible wheel is in a normal state as shown in fig. 1 and is normally meshed with the toothed plate and the extrusion plate, the meshing friction force at the moment belongs to a normal range, when the toothed wheel, the toothed plate and the extrusion plate are not in contact, the spring rod loses the limiting force and stretches, the friction force between the teeth and the toothed plate and the extrusion plate is large at the moment, and the closing speed of the door body tends to be stable; and the elasticity of the compression spring is greater than that of the spring rod, and the friction force between the teeth and the toothed plate and the extrusion plate is gradually reduced in the contraction process of the expansion wheel, so that the door body is opened more easily, and the effects of light door opening force and more stable door closing speed are achieved.
2. In the process of contraction and extension of the expansion and contraction wheel, after the liquid storage ring is pushed for a certain number of times, the oil pressure of lubricating oil in the expansion and contraction wheel is greater than the pressure of the permeable membrane, the lubricating oil can flow out for lubrication, meanwhile, the air bag is extruded to generate gas which flows to the surface of the expansion and contraction wheel from the hollow channel, and the flowing lubricating oil can be uniformly blown away, so that the effect of regular self-lubrication is achieved; in addition, the blown air flow can clean the joints of teeth, the toothed plate and the extrusion plate, and ensure the normal work of the teeth.
Preferably, the inside swing joint of connecting piece has the push rod, and the push rod plays the effect of connecting gasbag and stripper plate, and the gasbag of being convenient for is extruded.
Preferably, one end of the push rod, which is far away from the connecting piece, is movably connected with an air bag, the air bag can exhaust air when being extruded, and the elastic substance in the air bag can suck air under the action of self-restoring force when being stretched; when the gas is pumped, the excessive lubricating oil is pumped into the hollow channel for storage.
Preferably, one side of the air bag far away from the push rod is fixedly connected with a hollow channel, and the hollow channel plays a role in conveying gas and storing lubricating oil.
Preferably, the surface of the collapsible wheel is movably connected with a screw rod, and the screw rod is pushed by the connecting piece to rotate.
Preferably, the surface of the compression spring is sleeved with a telescopic rod, and the telescopic rod plays a role in enabling the compression spring to be connected with the extrusion plate all the time.
Preferably, the surface of the telescopic rod is movably connected with a roller, and the roller plays a role in reducing sliding friction force of the telescopic rod at the bottom of the extrusion plate.
Preferably, the collapsible wheel is composed of four parts, and each part is provided with teeth on the surface.
