Description

Field of invention

[0001] The present utility model relates to the technical field of door and window handles, in particular a handle for doors and windows. State of the art

[0002] Many types of door and window locks are known. To facilitate opening and closing doors and windows, handles are commonly attached to the locks. Typical door and window handles usually consist of a handle, a handle mounting base, and an actuator shaft. The handle is rotatably attached to the handle mounting base, while the actuator shaft is fixed to the handle. The actuator shaft interacts with the transmission unit of the door or window lock, so that turning the handle controls the movement of the transmission unit to lock or unlock the bolt or latch. Currently, most door and window handles on the market are attached to the handle mounting base by rivets.With these handles, it is difficult to replace individual components after assembly if, during quality control, the handle is found to be stiff, has paint damage or scratches, or the mounting base cover plate is deformed. Disassembly is complicated and can damage the handle mounting base, which usually results in the entire handle being discarded, thus wasting resources. Object of the invention

[0003] The aim of the present utility model is to solve at least one of the technical problems of the prior art and to provide a handle for doors and windows that allows for easy assembly and disassembly as well as uncomplicated replacement of components.

[0004] The present embodiment of the utility model provides a handle for doors and windows, comprising: a handle having a mounting column, wherein the outside of the mounting column has an annular groove and the inside has a drive cavity, a drive spindle for opening or closing doors and windows, wherein one end of the drive spindle is inserted into the drive cavity; a base which is provided with a first through-hole through which the mounting column is passed; a retaining ring fitted in the annular groove to limit the base on one side of the annular groove, the outer diameter of the retaining ring being larger than the diameter of the first through-hole.

[0005] According to an embodiment of the present utility model for a handle for doors and windows, at least the following advantageous effects are achieved: When mounting the handle, the mounting column of the handle is inserted through the first through-hole of the base, and the retaining ring is engaged in the annular groove of the mounting column. Since the outer diameter of the retaining ring is larger than the diameter of the first through-hole, the base can be pressed firmly into place. One end of the drive spindle is inserted into the drive cavity within the mounting column, so that the handle can rotate the drive spindle to enable the opening or closing of doors and windows.After the handle has been assembled, if a later quality check reveals that a component is damaged or scratched, the retaining ring can be removed from the ring groove to separate the handle from the base, allowing individual components to be replaced separately.

[0006] The handle can therefore be mounted and dismounted extremely conveniently.

[0007] The aforementioned door and window handle also includes a release retaining ring to prevent the drive spindle from loosening. This retaining ring is mounted on the mounting post and positioned between the base and the retaining ring. The mounting post has a recessed groove that communicates with the drive cavity. The release retaining ring features a release rib that passes through the recessed groove and presses against the drive spindle.

[0008] Due to the arrangement of the release retaining ring between the base and the retaining ring, and due to the recess groove on the mounting column which is connected to the drive cavity, the release retaining rib of the release retaining ring projects from the recess groove into the drive cavity. When the drive spindle is inserted into the drive cavity, the release retaining rib presses against the drive spindle, thus preventing the drive spindle from loosening.

[0009] The aforementioned handle for doors and windows has a mounting post with two of the aforementioned recess grooves, and the release locking ring is accordingly provided with two release locking ribs.

[0010] The aforementioned handle for doors and windows has a base with two mounting holes, each located on either side of the first through-hole.

[0011] The base is designed by the arrangement of two mounting holes on both sides of the first through-hole in such a way that the base can be attached to the door or window by means of screws through the first through-hole.

[0012] The aforementioned handle for doors and windows also includes a cover cap that snaps onto the base. This cover cap has a second through-hole for the mounting post. Snapping the cover cap onto the base allows the base's mounting holes and other internal structures to be concealed, resulting in a more aesthetically pleasing appearance.

[0013] The aforementioned door and window handle features a recessed opening on the side of the base for lifting the cover cap. This recessed opening makes it easier for the user to lift the cover cap.

[0014] The aforementioned handle for doors and windows also includes a rubber ring positioned between the cover cap and the handle. The placement of the rubber ring between the cover cap and the handle provides a damping effect.

[0015] The aforementioned door and window handle features a positioning groove on the outside of the mounting post and a corresponding positioning lug on the inside wall of the first through-hole. This positioning groove on the outside of the mounting post and the corresponding positioning lug on the inside wall of the first through-hole allow the handle to be rotated into a position where the groove and lug align, thus locking the handle in place. Further rotation of the handle requires greater force to overcome the resistance between the positioning groove and lug.

[0016] The aforementioned handle for doors and windows features several positioning grooves that are evenly spaced on the outside of the mounting column.

[0017] The aforementioned handle for doors and windows features a retaining ring with an opening, and third through-holes are arranged at the ends of both sides of the opening. These third through-holes allow the retaining ring to be attached to the ring groove of the mounting post.

[0018] Further features and advantages of the present utility models are described below and are partly evident from the description or become apparent from the design of the utility model. The objectives and further advantages of the utility model can be realized and achieved through the structures specifically indicated in the description, the claims, and the drawings.

[0033] With reference to Fig. 1 and Fig. 2. A recess opening 330 for lifting the cover cap 600 is arranged on the side surface of the base 300. The arrangement of the recess opening 330 on the side surface of the base 300 makes it easier for the user to lift the cover cap 600 at the recess opening 330.

[0034] With reference to Fig. 1 and Fig. 2. The aforementioned handle for doors and windows further comprises a rubber ring 700, which is arranged between the cover cap 600 and the handle 100. The arrangement of the rubber ring 700 between the cover cap 600 and the handle 100 provides a damping effect.

[0035] With reference to Fig. 1 and Fig. 2. A positioning groove 112 is arranged on the outside of the mounting column 110, and a positioning lug 311, which fits into the positioning groove 112, is arranged on the inside wall of the first through-hole 310. Due to the arrangement of the positioning groove 112 on the outside of the mounting column 110 and the corresponding positioning lug 311 on the inside wall of the first through-hole 310, the handle 100 can be rotated into a position in which the positioning groove 112 and the positioning lug 311 are aligned, thereby locking the handle in place. Further rotation of the handle 100 requires a greater force to overcome the resistance between the positioning groove 112 and the positioning lug 311 on the mounting column 110.
