Description

Technical Field

[0001] The utility model relates to the technical field of rotating rings for flagpoles, in particular to an anti-winding rotating ring for flagpoles. Background Art

[0002] A flag rope locking ring is generally provided on the cylinder through bolt locking. This ring structure is generally not adjustable, which is troublesome to install and inconvenient to fasten. Later, a rotatable fastening ring appeared. The inner side of this rotatable fastening ring is fixed to the flagpole, and the outer side can be rotated and adjusted. However, this rotating ring has the following disadvantages:

[0003] Firstly, the inner side of the rotating ring is a column structure with a fixed diameter, which has a single function and can only meet the fixed installation of the flagpole in one position. Moreover, since the inner column diameter of the rotating ring is fixed, it is inconvenient to install the slewing bearing, and the clamping effect of the slewing bearing is poor. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an anti-winding rotating ring for a flagpole, which can solve the problem that the inner column of a general anti-winding rotating ring for a flagpole adopts an integral cylindrical structure, resulting in inconvenient installation of the slewing bearing and unreliable assembly of the slewing bearing.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: an anti-winding rotating ring for a flagpole, the innovation of which is: comprising a flagpole jacket, a slewing bearing and a buckle ring;

[0006] The flagpole jacket is a shell-shaped column structure; an oblique groove is provided on the outer contour of the flagpole jacket, which is inclined to the generatrix direction of the flagpole jacket; a bolt locking hole is provided on the flagpole jacket; an annular groove is provided on the outer contour of the flagpole jacket;

[0007] The slewing bearing is arranged in the annular groove of the flagpole jacket;

[0008] The buckle ring is in a ring-shaped structure and is arranged on the outer contour of the slewing bearing. The top end of the buckle ring is bent inward and blocked above the slewing bearing. A buckle ear plate is arranged on the outer contour of the buckle ring. The bottom end of the flagpole jacket extends out of the lower surface of the buckle ring.

[0009] Furthermore, the top end of the flagpole jacket is turned outward to form an upper limit step; an annular groove for accommodating a slewing bearing is provided on the outer contour of the flagpole jacket below the upper limit step.

[0010] The advantages of the utility model are:

[0011] 1) In the utility model, the flagpole jacket is provided with a ring-shaped structure with a notch. When the slewing bearing on the flagpole jacket is installed, pinching the flagpole jacket can reduce the outer diameter of the flagpole jacket to facilitate the installation of the slewing bearing. In addition, after the overall assembly is completed, when the flagpole jacket is locked on the flagpole, the tightening action of the bolt can also drive the outer contour of the flagpole jacket to expand outwards and increase the outer diameter, thereby ensuring the limiting effect between the slewing bearing and the flagpole jacket and improving the stability of the slewing bearing after installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0015] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] like Figure 1 Figure 2 The anti-winding rotating ring for a flagpole shown in the figure comprises a flagpole jacket 1, a slewing bearing 2 and a buckle ring 3.

[0018] The flagpole jacket 1 is a shell-shaped column structure; an inclined groove 11 is provided on the outer contour of the flagpole jacket 1 and is inclined to the generatrix direction of the flagpole jacket 1; a bolt locking hole 12 is provided on the flagpole jacket 1; and an annular groove 13 is provided on the outer contour of the flagpole jacket 1.

[0019] The slewing bearing 2 is arranged in the annular groove 13 of the flagpole jacket.

[0020] The buckle ring 3 is a ring-shaped structure, and is arranged on the outer contour of the slewing bearing 2. The top end of the buckle ring 3 is bent inward and blocked above the slewing bearing 2. A buckle ear plate is arranged on the outer contour of the buckle ring 3. The bottom end of the flagpole jacket 1 extends out of the lower surface of the buckle ring 3.

[0021] The top end of the flagpole jacket 1 is turned outward to form an upper limit step; an annular groove 13 for accommodating a slewing bearing is provided on the outer contour of the flagpole jacket 1 below the upper limit step.

[0022] The working principle of the utility model is as follows: by arranging the flagpole jacket in a ring-shaped structure with a notch, when the slewing bearing on the flagpole jacket is installed, pinching the flagpole jacket can reduce the outer diameter of the flagpole jacket to facilitate the installation of the slewing bearing; in addition, after the overall assembly is completed, when the flagpole jacket is locked on the flagpole, the tightening action of the bolt can also drive the outer contour of the flagpole jacket to expand outwards and increase the outer diameter; thus, the limiting effect between the slewing bearing and the flagpole jacket is ensured, and the stability of the slewing bearing after installation is improved.
