Detailed Description
The invention will now be further described with reference to the accompanying description and examples:
example 1:
the utility model provides a magnetism speed reduction structure, as shown in fig. 1 and 2, including fixed casing 11, pivot connecting piece 12, magnetic part 13 and speed reduction cover 21, magnetic part 13 is magnet, magnetic part 13 and fixed casing 11 are along the rotatory circumference joint of pivot connecting piece 12, pivot connecting piece 12 is connected in the pivot of sunshade screen, speed reduction cover 21 is installed in pivot connecting piece 12, speed reduction cover 21 surface wholly is the cylinder that uses the rotation center of pivot connecting piece 12 as the axle center, speed reduction cover 21 and pivot connecting piece 12 circumference joint, be equipped with in the speed reduction cover 21 and hold chamber 22, it is equipped with magnetic conduction piece 23 in the chamber 22 to hold, it all is circular with speed reduction cover 21 axle center as the center to hold any cross section of chamber 22 along pivot connecting piece 12 rotation axle center direction, magnetic part 13 is located the radial one side of speed reduction cover 21.
The magnetic member 13 is located below the reduction sleeve 21.
The speed reducing sleeve 21 is fixedly connected with a supporting sleeve 26, the speed reducing sleeve 21 and the supporting sleeve 26 are coaxial, and the total volume of the magnetic conducting piece 23 is half of the volume of the accommodating cavity 22.
The magnetic conducting piece 23 is iron sand.
The speed reducing sleeve 21 is provided with a through hole 27 communicated with the accommodating cavity 22, the width of the through hole 27 is larger than that of the magnetic conducting piece 23, and the speed reducing sleeve 21 is provided with a sealing piece 28 for blocking the through hole 27.
The seal 28 is a plug screw threadedly coupled to the reduction sleeve 21.
The fixed shell 11 is provided with a clamping groove 14 matched with the magnetic part 13, and the extending direction of the clamping groove 14 is parallel to the rotating shaft center of the speed reducing sleeve 21.
Compared with the prior art, the invention has the beneficial effects that:
the rotating shaft connecting piece 12 is used for connecting a rotating shaft on the sun-shading curtain, when the rotating shaft rotates, the rotating shaft connecting piece 12 drives the speed reducing sleeve 21 to rotate, and when the speed reducing sleeve 21 bears resistance, the speed reducing sleeve 21 provides resistance for the rotation of the rotating shaft through the rotating shaft connecting piece 12 and reduces the rotating speed of the rotating shaft.
The magnetic member 13 causes the magnetic conductive member 23 to have a tendency to move toward the magnetic member 13 by a magnetic force. When the speed reducing sleeve 21 rotates, the magnetic conduction member 23 is kept at a position close to the magnetic member 13 under the action of the magnetic member 13, so that the magnetic conduction member 23 generates friction force with the inner wall of the speed reducing sleeve 21. Resistance is provided for the rotation of the speed reducing sleeve 21 through friction force, so that the effect of reducing the rotating speed of the rotating shaft is achieved, the advantage of conveniently controlling the rotating speed of the rotating shaft is achieved, the effect of preventing the curtain from being excessively unfolded and rolled can be achieved, and the use of the sunshade curtain is facilitated.
After the speed reducing sleeve 21 is used for a period of time, even if the inner wall of the speed reducing sleeve 21 is abraded to a certain extent, the magnetic part 13 still enables the magnetic conduction part 23 to be abutted against the inner wall of the speed reducing sleeve 21 and generate friction force, so that the speed reducing structure can continuously provide the function of reducing the rotating speed of the rotating shaft, and has high reliability.
Since the maximum static friction force of the surface of the rotating shaft is greater than the sliding friction force, the driving rotating shaft needs to overcome the greater maximum static friction force from the rest to the rotation, and since the rotating shaft has the inertia of keeping the rest state when the rotating shaft is at the rest, a greater driving force is needed to overcome the inertia effect when the rotating shaft is driven from the rest to the rotation. This speed reduction structure is when pivot and speed reduction cover 21 are static, and the trend of relative movement does not produce between magnetic conduction piece 23 and the speed reduction cover for magnetic conduction piece 23 at this moment does not obstruct speed reduction cover 21 and rotates, consequently can reduce the drive pivot and rotate the drive power that needs from static to pivoted in-process, plays laborsaving effect, makes things convenient for the use of sunshade screen.
The speed reducing structure is simple in structure, stable and reliable, and can reduce the influence of the abrasion of the speed reducing sleeve 21 on the speed reducing effect while keeping the resistance provided for the rotation of the rotating shaft.
The magnetic conduction piece 23 has a downward moving trend under the action of gravity, the magnetic piece 13 is positioned below the speed reduction sleeve 21, and the magnetic conduction piece 23 is driven to move towards the direction close to the magnetic piece 13 through the superposition of the action of gravity and the action of magnetic force, so that the friction force between the magnetic piece 13 and the speed reduction sleeve 21 can be further improved, the effect of blocking the rotation of the rotating shaft is improved, and the rotating speed of the rotating shaft is conveniently controlled.
The support sleeve 26 can provide a support force for the reduction sleeve 21, and the structural stability of the reduction sleeve 21 is improved. The speed reducing sleeve 21 is coaxial with the supporting sleeve 26, so that the position of the supporting sleeve 26 is unchanged when the speed reducing sleeve 21 drives the supporting sleeve 26 to rotate, and the magnetic conduction piece 23 is prevented from blocking the rotation of the supporting sleeve 26. The total volume of the magnetic conduction member 23 is half of the volume of the accommodating cavity 22, so that the height of the magnetic conduction member 23 does not exceed the central height of the speed reducing sleeve 21 when the magnetic conduction member is standing, the support sleeve 26 is prevented from providing upward support force for the magnetic conduction member 23, and the magnetic conduction member 23 is ensured to provide enough resistance for the speed reducing sleeve 21.
The magnetic conduction member 23 is placed in the speed reducing sleeve 21 through the through hole 27, so that the effect of conveniently placing the magnetic conduction member 23 in the accommodating cavity 22 is achieved. The sealing member 28 blocks the through hole 27, so that the magnetic conduction member 23 is prevented from accidentally sliding out of the accommodating chamber 22 through the through hole 27.
The screw plug is tightly twisted, and the screw plug is fixed on the speed reducing sleeve 21 through self-locking of the screw plug. The through hole 27 is blocked by the screw plug, so that the magnetic conduction piece 23 can be prevented from sliding out of the accommodating cavity 22.
In the rotation process of the speed reducing sleeve 21, iron sand can roll in the accommodating cavity 22, so that friction between the magnetic conducting member 23 and the speed reducing sleeve 21 is converted into rolling friction with smaller friction force, and the magnetic conducting member 23 can move towards the direction close to the magnetic member 13 more easily. The magnetic conduction member 23 is prevented from rotating circumferentially along with the speed reducing sleeve 21 due to the fact that the friction force between the magnetic conduction member 23 and the speed reducing sleeve 21 is too large, and the effects of improving reliability and stability are achieved.
The extending direction of the clamping groove 14 is parallel to the rotating axis of the speed reducing sleeve 21, and the fixed shell 11 can provide a circumferential supporting force for the magnetic part 13 in the clamping groove 14 to rotate the speed reducing sleeve 21, so that the magnetic part 13 is prevented from moving under the interaction with the magnetic conducting part 23.
In the direction of the rotation axis connector 12, the cross section of the accommodating cavity 22 is circular with the axis of the speed reducing sleeve 21 as the center, so that the center of the cross section of the accommodating cavity 22 is located on the rotation axis of the speed reducing sleeve 21. When the speed reducing sleeve 21 rotates, the distance between one end of the accommodating cavity 22 close to the magnetic part 13 and the magnetic part 13 is equal, so that the magnetic force between the magnetic part 13 and the magnetic conducting part 23 can be kept, the resistance of the speed reducing sleeve 21 and the rotating shaft is prevented from being changed greatly due to the fact that the magnetic force applied to the magnetic conducting part 23 is changed greatly, and the rotating stability of the rotating shaft is ensured.

The embodiment has the following advantages:
during the rotation of the speed reducing sleeve 21, the iron beads can roll in the accommodating cavity 22, so that the friction between the magnetic conducting member 23 and the speed reducing sleeve 21 is converted into rolling friction with smaller friction force, and the magnetic conducting member 23 can move towards the direction close to the magnetic member 13 more easily. The magnetic conduction member 23 is prevented from rotating circumferentially along with the speed reducing sleeve 21 due to the fact that the friction force between the magnetic conduction member 23 and the speed reducing sleeve 21 is too large, and the effects of improving reliability and stability are achieved. Provide stable resistance for the rotating shaft and conveniently control the rotating speed of the rotating shaft.
Example 4:
