[0014] Furthermore, the second connecting rod engages with the first slot, and each pair of second connecting rods has a second slot inside. A pair of movable rods are installed on the top of the slide plate, and a movable plate is slidably installed between the pair of movable rods.
[0015] The advantage of adopting the above-mentioned further solution is that by providing a movable plate, it is easy to move the insertion rod up and down, thereby enabling the installation and disassembly of the connecting plate.
[0016] Furthermore, a second spring is fitted around the outside of each pair of moving rods, and one end of each pair of second springs is connected to the moving plate. Insert rods are connected to both sides of the bottom of the moving plate, and the bottom end of each insert rod passes through the sliding plate and engages with the second slot.
[0017] The beneficial effect of adopting the above-mentioned further solution is that, by providing a second spring, the movable plate can move up and down on the movable rod, thereby driving the insertion rod to move.
[0018] The beneficial effects of this utility model are as follows: This utility model provides a door handle by placing the lock cylinder housing inside the door body and then fixing the mounting plate, thereby installing the rotating handle. When opening or closing the door, a pair of connecting plates can be pressed, and the user's hand rests on a pair of protective sleeves. The handle can then be rotated to open the door. The protective sleeves are made of sponge material, which absorbs moisture and impurities from the hands, protecting the rotating handle. When the protective sleeves become dirty, they can be pulled to separate the main and auxiliary Velcro straps. Replace and clean the protective sleeve, then attach the main and secondary Velcro straps together to install the sleeve. After that, release both hands, and the first spring will drive a pair of connecting plates back to their original positions. The slide plate will move on the slide rod, supporting the movement of the connecting plates. When the connecting plates are damaged after long-term use, pull the moving plate to drive a pair of insert rods upwards, separating the insert rods from the second slot. Then move the first and second connecting rods in the slide groove to facilitate the removal of the connecting plate from the slide plate for replacement. After that, reinstall the sleeve and protect the rotating handle to maintain its aesthetic appearance. Attached Figure Description

Connecting plates 2003 are slidably installed on both outer sides of the rotating handle 1003. A protective mechanism is provided on one side of each pair of connecting plates 2003, and the protective mechanism includes a pair of protective sleeves 2005. Slide plates 2007 are installed on both sides of each pair of connecting plates 2003, and first slots 3005 are provided on both inner sides of each pair of slide plates 2007. The internal parts of the 005 are equipped with an installation mechanism, which includes a pair of insert rods 3010. The rotating handle 1003 has a pair of grooves 2001 on both sides inside, and a first spring 2002 is connected inside each pair of grooves 2001. One end of each pair of first springs 2002 is connected to a pair of connecting plates 2003. The outer sides of each pair of connecting plates 2003 are provided with main Velcro 2004, and one side of each pair of connecting plates 2003 is attached with a protective sleeve 2005. The inner sides of the protective sleeve 2005 are provided with secondary Velcro 2004. The main Velcro 2004 and the secondary Velcro 2004 are glued together. By installing the first springs 2002, the connecting plates 2003 can be moved up and down to protect the rotating handle 1003 during use. The protective sleeve 2005, which is made of sponge material, can absorb moisture and impurities from the hands and protect the rotating handle 1003.
[0029] Embodiment 2 of the present invention: a door handle
[0030] For reference, specifically such as Figures 1-4The rotating handle 1003 has vertically mounted sliding rods 2006 on both sides near the groove 2001, and the sliding plate 2007 is sleeved on the outside of the sliding rods 2006. A keyhole 1008 is installed at the bottom of the lock cylinder housing 1001. The connecting plate 2003 has a pair of sliding grooves 3001 on both sides inside, and a limiting rod 3002 is connected inside each sliding groove 3001. A first connecting rod 3003 is slidably mounted on the outside of the limiting rod 3002, and a second connecting rod 3004 is connected to one end of the first connecting rod 3003. The second connecting rod 3004 engages with a first slot 3005, and a second slot 3006 is provided inside each pair of second connecting rods 3004. A pair of moving rods 3007 are mounted on the top of the sliding plate 2007, and a sliding joint is slidably mounted between the pair of moving rods 3007. The movable plate 3009 has a pair of movable rods 3007 each equipped with a second spring 3008, and one end of each second spring 3008 is connected to the movable plate 3009. Insert rods 3010 are connected to both sides of the bottom of the movable plate 3009, and the bottom end of each insert rod 3010 passes through the slide plate 2007 and engages with the second slot 3006. The first connecting rod 3003 and the second connecting rod 3004 are installed to fix the connecting plate 2003 and the slider together, allowing for the installation of the connecting plate 2003 and the protective sleeve 2005. The movable plate 3009 facilitates the up-and-down movement of the insert rods 3010, enabling the installation and removal of the connecting plate 2003. The second springs 3008 allow the movable plate 3009 to move up and down on the movable rods 3007, thus moving the insert rods 3010.
[0031] Specifically, the working principle of this type of door handle is as follows: During use, the lock cylinder housing 1001 is placed inside the door body, and then the mounting plate 1004 is fixedly installed, thereby installing the rotary handle 1003. When opening or closing the door, a pair of connecting plates 2003 can be pressed, and the user's hand is placed on a pair of protective sleeves 2005. The rotary handle 1003 can then be turned to open the door. The protective sleeves 2005 are made of sponge material, which can absorb moisture and impurities from the hands, protecting the rotary handle 1003. When the protective sleeves 2005 become dirty, they can be pulled to separate the main Velcro 2004 from the auxiliary Velcro 2005, allowing for replacement and cleaning of the protective sleeves 2005. Afterwards, the main Velcro 2004 can be reattached. 4. Attach the Velcro straps to each other and install the protective sleeve 2005. Then release both hands. The first spring 2002 drives a pair of connecting plates 2003 back to their original positions. The slide plate 2007 moves on the slide rod 2006, supporting the movement of the connecting plate 2003. When the connecting plate 2003 is damaged after long-term use, pull the moving plate 3009 to drive a pair of insert rods 3010 upwards, separating the insert rods 3010 from the second slot 3006. Then move the first connecting rod 3003 and the second connecting rod 3004 within the slide groove 3001 to facilitate the removal of the connecting plate 2003 from the slide plate 2007 for replacement. After that, reinstall it to protect the rotating handle 1003 and maintain its aesthetic appearance.
[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
