[0040] The following refers to Figures 1-6 A door handle installation device will be described in detail with a specific embodiment. It should be understood that the following description is only an exemplary illustration and not a specific limitation of the utility model.

[0041] As Figures 1-3 shown, a door handle installation device includes a rotating column 100 and a rotating sleeve 140.

[0042] Among them, the rotating column 100 is used to be installed in the installation hole of the door and protrude on both sides of the installation hole, and the cross-section is polygonal. The two ends of the rotating column 100 are respectively provided with a first screw 110 and a second screw 120 with opposite thread directions. The first screw 110 and the second screw 120 are respectively used for spiral connection with the door handles 130 on both sides; the rotating sleeve 140 is provided with a socket 150 that is in clearance fit with the rotating column 100. The length of the rotating sleeve 140 is less than the length of the rotating column 100. The rotating sleeve 140 is sleeved on the rotating column 100, and a fixing part is provided on the outer side of the rotating sleeve 140 for fixing the rotating sleeve 140 to drive the rotating sleeve 140 to rotate. During installation, the rotating column 100 is placed into the installation hole of the glass door and protrudes on both sides of the installation hole. On one side, the rotating sleeve 140 is in clearance fit through the socket 150. The first screw 110 and the second screw 120 are respectively used for docking with the door handles 130 on both sides. A tool is used to fix and drive the rotating sleeve 140 to rotate with the fixing plate of the rotating sleeve 140. Since the thread directions of the first screw 110 and the second screw 120 are opposite, the glass door handles 130 on both sides move closer to the middle. Finally, the glass door handles 130 on one side and the rotating sleeve 140 clamp the glass door, thereby completing the installation of the glass door handles 130 on both sides. Therefore, the handle 130 installation device has a simple structure, is convenient for installation, and the installation is locked firmly and is not prone to looseness during long-term use.

[0043] Specifically, as Figure 1 and Figure 2As shown, the cross-section of the rotating column 100 is square. Setting the rotating column 100 to be square is easy to process and is also beneficial for mating and installation with the socket 150. Moreover, the rotating sleeve 140 is cylindrical, and the fixing part is the jack 160 provided on the outer side of the cylinder. Making the rotating sleeve 140 cylindrical is easy to process and aesthetically pleasing, and having the fixing part as the jack 160 facilitates driving the rotation of the cylindrical rotating sleeve 140. Further, the jack 160 is a round hole. Setting the jack 160 as a circular shape is easy to process, and a round bar or a hex key can be used to insert into the jack 160 to drive the rotation of the rotating sleeve 140.

[0044] In some specific embodiments of the present utility model, as Figures 4-6 shown, the fixing part is two mutually parallel planes provided on the outer side of the rotating sleeve 140. Setting the fixing part in this way can drive the rotation of the rotating sleeve 140 by a wrench.

[0045] As Figure 4 shown, in the second embodiment of the present utility model, the cross-section of the rotating sleeve 140 is square. Setting the rotating sleeve 140 in this way is easy to process and convenient for using a wrench to drive the rotation of the rotating sleeve 140.

[0046] As Figure 5 shown, in the third embodiment of the present utility model, the cross-section of the rotating sleeve 140 is a regular hexagon. Setting the rotating sleeve 140 in this way is easy to process and convenient for using a wrench to drive the rotation of the rotating sleeve 140.

[0047] As Figure 6 shown, in the fourth embodiment of the present utility model, the cross-section of the rotating sleeve 140 is a regular octagon. Setting the rotating sleeve 140 in this way is easy to process and convenient for using a wrench to drive the rotation of the rotating sleeve 140.

[0048] It is worth mentioning that gaskets (the gaskets are not shown in the figure) are respectively provided on both sides of the rotating sleeve 140. Setting the gaskets can prevent the glass door from being scratched and at the same time play a role in clamping. In addition, the outer surface of the rotating sleeve 140 is treated by painting or electroplating. Through surface treatment of the rotating sleeve 140, corrosion can be prevented, the service life can be extended, and it is also beneficial for aesthetics.

[0049] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those of ordinary skill in the art.
