Description

Technical Field

[0001] The utility model relates to the technical field of hardware doors and windows, in particular to a handle without a base. Background Art

[0002] The handle is an essential operating component and visible component in the door and window system. Therefore, in addition to the invisible components, the handle is an extremely important component of the door and window system. It not only has to realize the required functions, but more importantly, it is the component that customers see most directly, so the appearance of the handle is very important; existing handles are usually divided into handles with base and handles without base. A handle with base means that the base part is exposed to the outside, while a handle without base means that the base part is not exposed to the outside but is located inside the handle of the handle; therefore, a handle without base can give customers a more atmospheric feeling.

[0003] In order to realize this function, most of the baseless handles on the market will cause the entire handle structure to be very complicated. In order to ensure that the handle is rotated into place every time, the prior art usually sets an angle limit with a spring steel ball structure in the base. However, since the structure of the baseless handle is limited by the volume, setting the angle limit structure in the base of the baseless handle will make the structure of the base of the baseless handle very complicated, thereby making the assembly of the base of the baseless handle troublesome, costly and difficult to assemble, resulting in extremely high assembly costs of the handle, which is not conducive to market development.

[0004] The announcement number is CN215632218U, which discloses a baseless handle, including a fixed seat with a rotating hole, a transmission shaft passing through the rotating hole, a transmission seat connected to the transmission shaft and abutting the fixed seat, and a handle connected to the transmission seat. The fixed seat is provided with a plurality of elastic positioning components at one end facing the transmission seat, and the plurality of elastic positioning components are arranged around the rotating hole. The fixed seat is also provided with a fixing hole for connecting a fixing screw between two adjacent elastic positioning components. The transmission seat is provided with a first positioning hole corresponding to the elastic positioning component and for the elastic positioning component to be embedded. The transmission seat is provided with an avoidance gap between two adjacent first positioning holes. In the baseless handle provided by the utility model, the transmission seat can avoid the fixing screw through the avoidance gap. When the user installs the fixing screw, there is no need to separate the transmission seat and the fixed seat. The elastic positioning component can be assembled at the factory, which effectively ensures the installation accuracy and stability, simplifies the installation process, and reduces the difficulty of disassembly and assembly. The handle has many overall parts, and the assembly process is relatively complicated and troublesome, which is time-consuming and laborious. Utility Model Content
