[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides a novel door handle structure, such as Figure 1-Figure 5 As shown, it includes an inner handle 1 and an outer handle 2, inner extension rods 11 are installed at both ends of the inner handle 1, and outer extension rods 21 are installed at both ends of the outer handle 2, a locking rod 3 is installed between the ends of the inner extension rod 11 and the outer extension rod 21, and a locking knob 4 is installed on the locking rod 3, an inner elbow 12 is installed at the outer end of the inner extension rod 11, and a threaded hole 121 is provided on the inner elbow 12, and an outer elbow 22 is installed at the outer end of the outer extension rod 21, and a locking rod mounting hole 221 is provided on the outer elbow 22, one end of the locking rod 3 is threadedly connected with the threaded hole 121, and the other end of the locking rod 3 is rotatably connected with the locking rod mounting hole 221, by screwing the locking knob 4, the locking rod 3 can be driven to rotate, so that the distance between the inner handle 1 and the outer handle 2 can be adjusted, and the locking adjustment can be realized after the inner handle 1 and the outer handle 2 are installed, and it can also be locked in time after loosening due to long-term use.

[0025] In this embodiment, sockets are provided at both ends of the inner handle 1 and the outer handle 2, and the inner extension rod 11 and the outer extension rod 21 are plugged into the corresponding sockets to facilitate the extension of the inner extension rod 11 and the outer extension rod 21 and adjust the length of the entire handle to suit different door body needs.

[0026] Specifically, an inner washer 5 is installed at the end of the inner extension rod 11 to provide a certain buffering effect.

[0027] Furthermore, the locking rod 3 includes a threaded end 31 and a hexagonal end 32 , and the threaded end 31 and the hexagonal end 32 are an integrally formed structure, which ensures the strength of the locking rod 3 and prevents it from breaking.

[0028] Furthermore, the threaded end 31 is threadedly connected to the threaded hole 121 , and one end of the hexagonal end 32 is inserted into the locking rod mounting hole 221 and is rotatably connected to the outer elbow 22 via a bearing 33 , so as to facilitate the flexible rotation of the locking rod 3 .

[0029] Furthermore, a hexagonal opening 43 is provided in the middle of the locking knob 4, and the hexagonal end 32 passes through the hexagonal opening 43. The locking knob 4 rotates to drive the locking rod 3 to rotate through the cooperation between the hexagonal end 32 and the hexagonal opening 43, so that one end of the locking rod 3 is screwed into or out of the inner elbow 12.

[0030] Furthermore, the outer wall of the locking knob 4 is provided with anti-skid patterns 41, which provide a good anti-skid effect when the knob is turned.

[0031] Furthermore, an outer gasket 42 is provided on one side of the locking knob 4 close to the outer elbow 22 to ensure a certain buffering effect.

[0032] The novel door handle structure of the utility model mainly relies on its unique design to achieve a stable connection and convenient adjustment between the inner handle 1 and the outer handle 2 when in use. Specifically, when the user needs to install or adjust the door handle, the inner extension rod 11 and the outer extension rod 21 are first inserted into the sockets at both ends of the inner handle 1 and the outer handle 2 to achieve plug-in matching. This design allows the user to flexibly adjust the length of the entire handle according to the actual thickness and needs of the door body to adapt to different installation environments.

[0033] Then, the user will further adjust the locking by turning the locking knob 4. A hexagonal opening 43 is provided in the middle of the locking knob 4, and this design enables it to fit tightly with the hexagonal end 32 of the locking rod 3. When the user rotates the locking knob 4, the hexagonal end 32 will rotate accordingly, and since the threaded end 31 is threadedly connected to the threaded hole 121 on the inner elbow 12, one end of the locking rod 3 will be screwed into or out of the inner elbow 12, thereby changing the distance between the inner handle 1 and the outer handle 2, and realizing the adjustment of the locking.

[0034] In addition, the hexagonal end 32 of the locking rod 3 is also rotatably connected to the outer elbow 22 via a bearing 33. This design ensures the flexibility of the locking rod 3 during rotation, allowing the user to easily perform locking and adjustment operations.

[0035] During the entire use process, the inner washer 5 at the end of the inner extension rod 11 and the outer washer 42 on the side of the locking knob 4 close to the outer elbow 22 both play a certain buffering effect, protecting the door handle structure from damage and improving the comfort of use. The anti-slip pattern 41 on the outer wall of the locking knob 4 ensures that the user can hold the knob firmly when turning it without slipping.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
