In this way, at least two decoration cover fixing screws and gourd-shaped holes formed in the bottom face of the decoration cover can be omitted, the situation that the decoration cover fixing screws and the gourd-shaped holes are exposed to affect the overall attractiveness of the ceiling fan is avoided, and therefore the ceiling fan is convenient to install and use, and the attractiveness of the ceiling fan after being installed and used can be improved.

Description

Technical Field

[0001] The utility model relates to a ceiling fan, in particular to a mounting structure of a decorative cover (commonly known as an upper hanging bell) at the top of the ceiling fan. Background Art

[0002] We know that when ceiling fans are installed, they are hung by hanging rods and hangers, and the hangers are installed on the ceiling. At this time, in order to avoid the hangers on the ceiling, hanger mounting screws and circuit controllers placed in the hangers from being exposed and affecting the appearance, people often use decorative covers (commonly known as hanging bells) to cover them. Figures 1 to 3 As shown, it is necessary to screw at least two decorative cover fixing screws 200 on the hanger 100 and open at least two gourd holes 301 on the bottom surface of the upper decorative cover 300 (including a large hole for the screw head to enter and exit and a small hole for the screw to slide horizontally and smaller than the screw head). When installing the upper decorative cover 300, the upper decorative cover 300 is inserted from the lower end of the suspension rod 400, and the large hole of the gourd hole 301 of the upper decorative cover 300 is aligned with the decorative cover fixing screw 200 on the hanger 100 and then covered. When the screw head 201 of the decorative cover fixing screw 200 is exposed through the large hole, the upper decorative cover 300 is horizontally rotated to make the decorative cover fixing screw 200 slide horizontally into the small hole of the gourd hole 301. At this time, the screw head 201 of the decorative cover fixing screw 200 is exposed outside the upper decorative cover 330, so as to support the upper decorative cover and prevent it from falling down.

[0003] As can be seen from the above, the installation of the upper decorative cover is not very convenient (it is necessary to tighten at least two decorative cover fixing screws 200 and rotate the upper decorative cover horizontally). In addition, since the screw heads 201 of the decorative cover fixing screws 200 and the gourd holes 301 of the upper decorative cover 300 are exposed, this also affects the overall appearance of the ceiling fan to a certain extent. Summary of the invention

[0004] The utility model aims to overcome the shortcomings of the prior art and provides a mounting structure for a decorative cover on a ceiling fan which is easy to install and can make the ceiling fan more beautiful after installation and use.

[0005] In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions:

[0006] A mounting structure for a ceiling fan upper decorative cover comprises a hanger, a hanger rod, an upper decorative cover and a decorative cover, wherein:

[0007] The upper end of the hanger is fixed to the ceiling, and the lower end is provided with a hanger rod mounting socket;

[0008] The upper end of the boom is provided with a boom head which can be inserted into the boom installation slot;

[0009] The upper decorative cover is inserted from the lower part of the suspension rod and then covers the outside of the suspension bracket; an outer thread is provided on the outer wall of the insertion hole of the upper decorative cover and a cone is provided at the outer end; a vertical notch is provided on the outer wall of the outer thread;

[0010] An inner thread matching the outer thread is provided on the inner wall of the hollow hole of the decorative cover, and a shrinking opening capable of radially narrowing the cone opening inward is provided at the outer end; when the decorative cover is inserted from the lower part of the suspension rod and screwed onto the outer thread, the shrinking opening acts on the cone opening to tighten the inserted hole.

[0011] In an improved solution to the mounting structure of the decorative cover on the ceiling fan, the contraction opening of the decorative cover is a conical trumpet opening.

[0012] In an improved solution to the installation structure of the upper decorative cover of the ceiling fan, there are two to four vertical notches on the upper decorative cover.

[0013] In an improved solution to the mounting structure of the decorative cover on the ceiling fan, the decorative cover and the internal screw thread on the inner wall of the hollow hole are integrally injection molded; and a straight guide groove is provided on the inner wall of the hollow hole of the decorative cover during injection molding.

[0014] Compared with the prior art, the utility model has the following beneficial effects: since the decorative cover with an internal threaded hole and a shrinkage opening is screwed on the external threaded thread with a vertical notch and a cone opening of the upper decorative cover, the shrinkage opening acts on the cone opening to tighten the insertion hole by slightly elastic deformation, so that the insertion hole at the bottom of the upper decorative cover is tightly held on the suspension rod to fix the upper decorative cover, thereby eliminating at least two decorative cover fixing screws and a gourd hole opened on the bottom surface of the decorative cover, and the overall appearance of the ceiling fan will not be affected by the exposure of the decorative cover fixing screws and the gourd hole. Therefore, the utility model is easy to install and use, and can improve the appearance of the ceiling fan after installation and use.
