Problems solved by technology

The machining accuracy of the bearing installation part will be improved, which will increase the difficulty of the process
In addition, the adapter shaft will be treated with anti-rust treatment, and the surface will be sprayed with plastic. After spraying, the bearing installation part must undergo secondary processing before the bearing can be installed. The entire production process is cumbersome and the cost is too high. high maintenance cost
[0004] In addition, in the above-mentioned documents, the installation position of the bearing is the stress point of the adapter shaft. The distance between the two stress points is too close to provide stable support for the adapter shaft, and it is easy to shake during operation, resulting in the adjustment device as a whole. The fixing strength is weak and the stability is poor

Embodiment 1

[0034] Such as Figure 5As shown, a circle of oil thread groove I 1011 is set on the support part 101, and a circle of oil thread groove II 1031 is arranged on the side wall of the sealing end cover 103, and the oil thread groove I 1011 and the oil thread groove II 1031 are filled with High-temperature lubricating grease, high-temperature grease is usually in a solidified state. When the rotating mechanism is in operation, mechanical energy is converted into heat energy, making the grease into a molten state to achieve the effect of lubrication. Oil thread groove I 1011 and oil thread groove II 1031 replace traditional bearings and serve as force supporting points to support the rotation of the rotor 10. The inner surface A114 of the casing on the casing 11 corresponds to the oil thread groove II 1031, and the inner surface B115 of the casing corresponds to the oil thread groove I 1011 Correspondingly, both the inner surface A114 of the housing and the inner surface B115 of th...

Embodiment 2

[0036] Such as Figure 6-7 As shown, an annular sealing ring 131 is provided in both the oil thread groove I 1011 and the oil thread groove II 1031, and the annular sealing ring 131 is made of rubber material, and a steel ring 132 is arranged in the annular sealing ring 131, and the The cross-sections of the annular sealing ring 131 and the steel ring 132 are both U-shaped, and the strength and rigidity of the steel ring 132 can prevent the deformation of the annular sealing ring and avoid the reduction of sealing performance. A trapezoidal groove 133 with a trapezoidal cross-section. The groove 133 is provided with a sealing strip 134 matching the trapezoidal groove. The sealing strip 134 is also made of rubber material, and the high-temperature lubricating grease is filled in the annular sealing ring Inside. The sealing strip can strengthen the sealing performance of the annular sealing ring and prevent the leakage of high-temperature lubricating grease.

Abstract

The invention particularly relates to a rotating mechanism facilitating rotation of an umbrella cover, belonging to the technical field of sunshades. The mechanism comprises a rotating core, a shell and a handle, wherein one end of the rotating core is arranged in the shell; the handle is mounted on the outer wall of the shell; lock teeth are arranged on the handle, penetrate through the outer wall of the shell and act on the rotating core; the part, located in the shell, of the rotating core is provided with a supporting part, a locking part and a sealing end cover; the supporting part and the sealing end cover serve as force bearing points for rotation of the rotating core to be in butt joint with the shell, the locking part is provided with positioning teeth, and the lock teeth are meshed with the positioning teeth when the handle is locked. Oil line grooves or blind holes with an oil storage function are adopted as stress supporting points, rotary supporting is provided for the rotating core, the production cost is saved, and the manufacturing process is simplified; and under the condition of no limitation of a mounting position of a bearing, the distance between the two stresssupporting points on the rotating core can be increased, so that the rotating core is supported more stably and firmly, and the rotating core rotates more stably.

Description

technical field [0001] The invention belongs to the technical field of parasols, in particular to a rotating mechanism that facilitates the rotation of an umbrella surface. Background technique [0002] Sun umbrellas are widely used in people's daily life. When using sun umbrellas, due to the movement of the sun, the angle of sunlight changes. It is necessary to adjust the inclination angle of the umbrella surface of the sun umbrella accordingly to achieve the purpose of effective sunshade. [0003] A kind of device for adjusting the angle of the umbrella surface is disclosed in the patent document of publication number CN108477784A, as figure 1 As shown, this document records that when the transfer shaft is connected to the housing and rotates relative to each other, the bearings installed at the two places of the transfer shaft and as support. The machining accuracy of the bearing installation part will be improved, which increases the difficulty of the process. More...
