Description

Technical Field

[0001] This utility model relates to the field of windows and doors, specifically a window and door handle that is easy to assemble. Background Technology

[0002] Windows and doors are usually equipped with handles to unlock and open them. Existing handles are installed on windows and doors via bases, and the handles can rotate relative to the bases to lock or unlock the windows and doors.

[0003] To keep mosquitoes away, people usually install screen doors or windows on the inside of doors or windows (such as...). Figure 1 As shown), the handle 2' is set in the narrow space 3' between the door and the screen door or the window and the screen window. The size of the narrow space 3' depends on the thickness of the window and door profile 1'. That is, the height of the handle 2' limits the window and door profile 1' to a certain thickness so that the narrow space 3' can accommodate the handle 2' sufficiently.

[0004] Therefore, reducing the height of the handle can reduce the thickness of the window and door profiles, thereby reducing material consumption. However, due to the current design limitations of the handle, the rotating mechanism is usually located inside the base, which prevents the height of the base from being further reduced, thus preventing the handle height from being improved and reduced in this aspect.

[0005] In response to the above situation, the applicant designed a door and window handle that sets the rotating mechanism on the handle and achieves a modular assembly through the sleeve cavity, thereby reducing the height of the handle. The applicant believes that the door and window handle can be further improved to make its structure simpler, optimize the production process, and make it more conducive to modification and expansion. Summary of the Invention

[0006] In order to overcome the shortcomings of the existing technology, this utility model provides a window and door handle that is easy to assemble.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A window / door handle that is easy to assemble includes a handle and a mounting base. The mounting base has a protruding sleeve. The back of the handle has a sleeve cavity that mates with the sleeve. A rotating shaft is provided inside the sleeve cavity. A spring-loaded mechanism is arranged in the space between the inner wall of the sleeve cavity and the rotating shaft. A limiting structure is provided on the top wall of the sleeve. The handle is fitted into the sleeve cavity. The rotating shaft passes through the sleeve to realize the rotatable connection between the handle and the mounting base. The top of the sleeve extends into the space between the inner wall of the sleeve cavity and the rotating shaft so that the limiting structure and the spring-loaded mechanism are engaged.

[0009] The limiting structure includes two or more limiting grooves distributed around the axis of the sleeve, and the retractable mechanism is provided with an elastic element that can be elastically extended and retracted to cooperate with the limiting grooves to limit the rotation of the handle.

[0010] The limiting grooves are four in number and are evenly distributed on the top wall of the sleeve.

[0011] The spring mechanism has four sets of corresponding limiting grooves.

[0012] The elastic element is a ball that is elastically driven by a spring.

[0013] The top wall of the sleeve cavity is provided with an installation cavity for accommodating the retractable mechanism, and the elastic element of the retractable mechanism faces downward and cooperates with the limiting groove.

[0014] The rotating shaft is detachably installed inside the sleeve cavity.

[0015] The top of the rotating shaft is provided with a mounting hole, and the top wall of the sleeve cavity is provided with a threaded hole corresponding to the mounting hole. The screw passes through the mounting hole and connects with the threaded hole to fix the rotating shaft inside the sleeve cavity.

[0016] The rotating shaft has a bent portion at its end. After passing through the bottom opening of the sleeve, the rotating shaft bends outward through the bent portion and abuts against the bottom of the sleeve.

[0017] The rotating shaft is provided with a transmission hole for inserting a transmission shaft.

[0018] The beneficial effects of this utility model are as follows: This utility model achieves rotational installation with the mounting base by setting a sleeve cavity on the handle, thereby reducing the installation height between the handle and the mounting base. On this basis, the space between the sleeve cavity and the rotating shaft is rationally utilized to arrange the spring-loaded structure, simplifying the structure of the mounting base and making the structure of the mounting base shorter, further reducing the height of the handle. Furthermore, by setting a limiting structure at the top of the sleeve to cooperate with the spring-loaded mechanism, the assembly relationship between the sleeve, the sleeve cavity, and the rotating shaft is fully utilized to arrange the combination of the spring-loaded mechanism and the limiting structure, simplifying the assembly process. Moreover, the spring-loaded mechanism is arranged inside the sleeve cavity, which does not affect the shape of the handle or the connection structure of the rotating shaft, and can be modified more easily to meet customer needs, so that the spring-loaded mechanism can be adapted to handles of more door and window types.

[0025] Reference Figures 2 to 5 A window and door handle that is easy to assemble includes a handle 2 and a mounting base 1. The mounting base 1 has a protruding sleeve 3. The back of the handle 2 has a sleeve cavity 4 that mates with the sleeve 3. The sleeve cavity 4 has a rotating shaft 5. A spring-loaded mechanism is arranged in the space between the inner wall of the sleeve cavity 4 and the rotating shaft 5. The top wall of the sleeve 3 has a limiting structure. The handle 2 is fitted into the sleeve 3 through the sleeve cavity 4. The rotating shaft 5 passes through the sleeve 3 to realize the rotatable connection between the handle 2 and the mounting base 1. The top of the sleeve 3 extends into the space between the inner wall of the sleeve cavity 4 and the rotating shaft 5 so that the limiting structure and the spring-loaded mechanism are engaged. In this way, the assembly relationship between the sleeve 3, the sleeve cavity 4 and the rotating shaft 5 is fully utilized to combine the spring-loaded mechanism and the limiting structure, simplifying the assembly process.

[0026] As a preferred embodiment of this utility model, the limiting structure includes two or more limiting grooves 6 distributed around the axis of the sleeve. The retractable mechanism is provided with elastic elements 7 that can be elastically extended and retracted, and the number of elastic elements 7 can be increased according to needs. For example, when there are one or two elastic elements 7, the limiting points formed by each limiting groove 6 define the rotation angle stop position of the handle 2. The stop position can indicate the locked state of the window and door lock body, allowing the user to clearly know that the handle 2 has been rotated to the correct position and has been unlocked or locked. In the unlocked or locked state, a certain torque is applied to the handle to prevent the handle from easily rotating and losing its current state due to gravity or slight touch, which is more conducive to the user's next operation. When there are two or more elastic elements 7, such as Figure 3 As shown, there are 4 elastic elements 7 and 4 corresponding limiting grooves 6. The handle 2 can trigger the cooperation of the spring mechanism and the limiting structure by turning it to the left or right, which makes the installation adaptability of this utility model higher and brings a clear operating feel.

[0027] The elastic element 7 can be implemented using either a ball or a spring, such as... Figure 4 , Figure 5 As shown, this embodiment preferably employs a ball bearing driven by a spring, allowing the ball to roll out of the limiting groove 6, making the user's operation more effortless. Furthermore, the top wall of the sleeve cavity 4 is provided with a mounting cavity 42 for accommodating the retractable mechanism. The retractable mechanism is housed in the mounting cavity 42, with the elastic element 7 facing downwards and engaging with the limiting groove 6. This allows the ball bearing to roll directly along the top wall of the sleeve 3, resulting in smoother engagement with the limiting groove 6.

[0028] The rotating shaft 5 and the sleeve cavity 4 of this utility model can be arranged in an integrated or separate manner. Preferably, the rotating shaft 5 and the sleeve cavity 4 are detachable. The top of the rotating shaft 5 is provided with a mounting hole 53, and the top wall of the sleeve cavity 4 is provided with a threaded hole 41 corresponding to the mounting hole 53. The rotating shaft 5 passes through the sleeve 3 and is installed into the sleeve cavity 4. The screw 92 is inserted into the transmission hole 52, passes through the mounting hole 53 and connects with the threaded hole 41 to fix the rotating shaft 5 in the sleeve cavity 4. The end of the rotating shaft 5 is provided with a bent part 51. After the rotating shaft 5 passes through the bottom opening of the sleeve 3, it bends outward through the bent part 51 and abuts against the bottom of the sleeve 3. A gasket is sandwiched between the bent part 51 and the bottom of the sleeve 3, so that the handle 2 can be fixed relative to the axis of the sleeve 3. At the same time, the assembly of the handle 2 and the mounting base 1 is realized, making the assembly and connection between the handle 2 and the mounting base 1 more convenient.

[0029] Furthermore, the retractable mechanism is arranged inside the sleeve cavity 4, which does not affect the shape of the handle 2 or the connection structure of the rotating shaft 5. It can be modified more easily to meet customer needs, so that the retractable mechanism can be adapted to the structure of the handle rotating shaft of more types of doors and windows. For example, when the door and window adopts an internal lock body structure, the handle needs to be connected to the lock body through the transmission shaft 8. At this time, the rotating shaft 5 is provided with a transmission hole 52 for the transmission shaft 8 to be inserted. By rotating the handle 2, the lock body inside the window and door can be driven to work to lock or unlock the window and door.

[0030] This utility model achieves rotatable installation with the mounting base 1 by setting a sleeve cavity 4 on the handle 2, thereby reducing the installation height between the handle 2 and the mounting base 1. Furthermore, it makes reasonable use of the space between the sleeve cavity 4 and the rotating shaft 5 to arrange the spring-loaded structure, simplifying the structure of the mounting base and making the structure of the mounting base 1 shorter, further reducing the height of the handle.
