[0031] See also Figures 1 to 11 The utility model relates to a baseless handle, which is composed of four parts: a handle 10, a handle head 20, a mounting base 30 and a shaft assembly 40. The handle 10 is fixed to one end of the handle head 20, and the other end of the handle head 20 is detachably plugged and assembled with the mounting base 30. The shaft assembly 40 passes through the mounting base 30 and is fixed to the handle head 20, which is convenient for assembling the baseless handle, has no exposed screws, has a good overall appearance, and improves the user experience.

[0032] The handle head 20 includes a cavity 21 and a plug connector 22. The cavity 21 is provided with a cavity and a threaded hole connected to the cavity. The middle part of the plug connector 22 is provided with an avoidance hole 220 running through both ends. The plug connector 22 is nested in the cavity. An end of the plug connector 22 exposed from the cavity 21 is provided with a plug column 221, and the plug column 221 is provided with a bayonet 2211 along the height direction.

[0033] The mounting seat 30 includes a fixing seat 31 and a decorative seat 32. The fixing seat 31 is used to be fixed to the door and window, and the decorative seat 32 is sleeved on the outside of the fixing seat 31.

In addition, by providing a support spring 33 between the fixed seat 31 and the decorative seat 32, the plug-in column 221 can automatically hook the snap-in tongue 321. The support spring 33 can be compressed when the decorative seat 32 is pressurized to make the snap-in tongue 321 disengage from the bayonet 2211 of the plug-in column 221, thereby realizing the separation of the handle head 20 and the decorative seat 32. The assembly and disassembly process of the handle is convenient and quick, and there is no need to fasten it with screws, which avoids the exposure of the screws and improves the user experience.

[0036] In one embodiment, a first mounting shaft 312 is provided on the inner side of the fixing seat 31, and an L-shaped mounting plate is provided on the inner side of the decorative seat 32. The L-shaped mounting plate includes a transverse plate and a longitudinal plate connected to each other.

The second mounting shaft 322 is coaxial with the first mounting shaft 312 and has a gap setting. The two ends of the support spring 33 are respectively sleeved on the first mounting shaft 312 and the second mounting shaft 322.

[0037] In one embodiment, the plug post 221 is provided with a first guide slope 2212 at one end away from the end face of the plug connector 22; the latching tongue piece 321 is provided with a second guide slope 3211 that matches the first guide slope 2212 on the side facing the end face of the plug connector 22. When the plug post 221 and the latching tongue piece 321 are assembled, the first guide slope 2212 first abuts against the second guide slope 3211 and slides downward along the second guide slope, so that the plug post 221 is gradually Entering the snap-in notch, the support spring 33 is compressed during the process of the plug-in column 221 entering the snap-in notch. When the snap-in tongue 321 is aligned with the snap-in notch 2211 of the plug-in column, the support spring 33 gradually resets and causes the snap-in tongue 321 to be embedded in the snap-in notch 2211, that is, the plug-in column 221 hooks the snap-in tongue 321, completing the assembly of the plug connector 22 and the mounting seat 30. Thus, the plug-in column 221 and the snap-in tongue 321 are quickly assembled by connecting the guide slopes. Correspondingly, the plug-in column 221 is also provided with a yielding slope 2213 on one side of the snap-in notch 2211 close to the end face of the plug connector 22, so as to avoid the second guide slope 3211.

[0038] In one embodiment, the handle head 20 also includes a steel ball spring 23 and a gasket 24. The gasket 24 is provided with a center hole 240 and a plurality of pause holes 241 arranged around the center hole 240. The steel ball spring 23 includes a mounting spring and a steel ball fixed to one end of the mounting spring. The steel ball spring 23 is rotatably partially embedded in the pause hole 241.

[0039] The plug connector 22 is provided with a plurality of spring installation grooves 222 around the avoidance hole 220 at one end away from the plug post 221. The gasket 24 is sleeved on the adapter 43 in such a way that its central hole 240 is aligned with the avoidance hole 220 of the plug connector 22 and can rotate relative to the plug connector 22. The end of the steel ball spring 23 away from the steel ball is embedded in the spring installation groove 222.

[0040] By providing a steel ball spring 23 and a corresponding pause hole 241, the steel ball of the steel ball spring 23 can be partially stuck in the pause hole 241 when the handle is rotated to a certain angle, producing a pause feeling and a "click" sound effect, thereby improving the feel and fun of the handle when used and enhancing the user experience.

[0041] In one embodiment, the plurality of pause holes 241 include four start-stop pause holes 2411, and the four start-stop pause holes 2411 are evenly distributed on the gasket 24 along the circumferential direction; the steel ball springs 23 are provided with four, and when rotated into place, they are embedded in the four start-stop pause holes 2411 one by one.

[0042] In one embodiment, the multiple pause holes 241 also include an intermediate pause hole 2412, the aperture of the intermediate pause hole 2412 is smaller than the start and end pause holes 2411, and the intermediate pause hole 2412 is arranged between two adjacent start and end pause holes 2411, and the center of the intermediate pause hole 2412 is arranged cocircularly with the center of the start and end pause holes 2411.

[0043] It can be understood that the start and end stop holes 2411 are the stop holes 241 when the handle is rotated 0° and 90°, and the middle stop hole 2412 is an intermediate angle between 0° and 90°, such as 30°, 45°, 60°, etc., which can be set according to actual needs.

[0044] In one embodiment, a mounting notch 242 is provided at the edge of the gasket 24 , and the mounting notch 242 is used to cooperate with a preset protrusion on the inner side of the cavity 21 so that the gasket 24 rotates synchronously with the handle 10 .
