Detailed Description

To make the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

As shown in fig. 1, the fan with the detachable columns according to the present application includes a base 3 and a mesh enclosure assembly 5, and the detachable columns 2 are disposed between the base 3 and the mesh enclosure assembly 5, so that the columns can be conveniently detached from the base 3 and the mesh enclosure assembly 5, respectively. As shown in fig. 2-4, the screen assembly 5 has a connector 1 fixedly coupled thereto, and the connector 1 may be in the form of a connecting rod. The bottom of the connecting piece 1 is provided with a connecting thread 14 and a protruding part, the center of the protruding part is provided with a female plug 13, for example, the female plug can be a DC female plug, and the protruding part is provided with two upright post holes 12 and a first limiting plane 11. The top of the upright post 2 is provided with an inserting part with an accommodating cavity, and the inserting part is in threaded connection with the protruding part at the bottom of the connecting piece. The center of the accommodating cavity is provided with a male plug 23, and the male plug 23 can be inserted into the female plug 13 and is in plug fit with the female plug. The accommodating cavity of the insertion part is provided with a limiting upright post 22 and a second limiting plane 21. During installation, the limiting upright post 22 is inserted into the upright post hole 12, and the second limiting plane 21 is matched with the first limiting plane 11 for limiting. The inserting part can be a threaded sleeve, and the lower end of the threaded sleeve is provided with a flanging 24 for limiting during installation; the first limiting plane and the second limiting plane can be non-inclined vertical planes.

The screen panel subassembly in this application can be dismantled with the stand and be connected, and wherein inside is accompanied with can the circular telegram DC male and female and insert, need lock through the screw thread sleeve pipe on the stand and the screw thread of connecting piece during the use. When inserting, the protruding portion design of connecting piece has the spacing plane that prevents the dislocation joint, mutually supports with stand screw thread sleeve's spacing plane department, appears inserting the phenomenon of turning over when avoiding inserting. The spacing stand hole of both sides can be fixed more effectively. After the insertion, the locking is carried out through the screw thread, and the top of the upright post and the flanging 24 are limited and fixed.

As shown in fig. 5-6, the bottom end of the upright post 2 is provided with an inserting part, a male plug 41 is arranged in the inserting part, the inner wall of the inserting part is provided with a thread, and the tail end of the thread is provided with a first thread limiting plane 42. The base 3 is provided with a female plug 31 which is in plug-in fit with the male plug 41, and is also provided with a protruding part which is in threaded fit connection with the plug-in part, the outer side of the protruding part is provided with threads, and the end part of the lower threads is provided with a second thread limiting plane 32 which is in fit limit with the first thread limiting plane 42.

The stand in this application and base also can dismantle the connection, and inside also is equipped with the DC public mother that can switch on and inserts, carries out the assembly of stand and base through the screw during use. Because the head faces only in the fixed forward direction, the thread end face limitation is performed at the thread part where the upright post and the base are matched, namely, the thread end face limitation is realized through the first thread limiting plane 42 and the second thread limiting plane 32.
