[0003] In order to prevent mosquitoes, people usually install screen doors or screen windows on the indoor side of doors or windows (such as Figure 1 As shown), the handle 2' is arranged in the narrow space 3' between the door and the screen door or the window and the screen window, and 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 thickness of the window and door profile 1' so as to obtain a narrow space 3' sufficient to accommodate the handle 2'.

[0004] Therefore, lowering the height of the handle can reduce the thickness of the window and door profiles and thus reduce material consumption. However, due to the current design of the handle, the handle usually has a rotating mechanism disposed in the base, so that the height of the base cannot be further reduced, and thus the height of the handle cannot be improved and reduced in this aspect.

[0036] Reference Figures 2 to 14 A window and door handle includes a handle 2 and a mounting base 1, wherein the mounting base 1 is protruded with a through sleeve 3, a sleeve cavity 4 cooperating with the sleeve 3 is provided on the back of the handle 2, a rotating shaft 5 is provided in the sleeve cavity 4, the handle 2 inserts the sleeve 3 into the sleeve cavity 4, and the rotating shaft 5 penetrates into the sleeve 3 to realize the rotation connection between the handle 2 and the mounting base 1, and the elastic shrinkage mechanism and the limiting structure cooperating with the elastic shrinkage mechanism are respectively arranged on the rotating shaft 5 and the inner side wall of the sleeve 3, and are arranged together with the rotating shaft 5 and the sleeve 3 in the sleeve cavity 4 to form a mutually nested assembly relationship, which simplifies the structure of the mounting base 1 on the one hand, thereby reducing the height, and on the other hand, the mutually nested structure also greatly reduces the installation height between the handle 2 and the mounting base 1, thereby achieving the purpose of reducing the overall height of the handle. In addition, the body of the handle 2 does not need to be overly designed because the elastic shrinkage mechanism is not required, so that the structure of the handle 2 can be simplified, and the elastic shrinkage mechanism is arranged on the rotating shaft 5 as the core component of the rotation connection, which can be transformed more easily in response to customer needs. For example, if it is necessary to provide a larger torque for the handle to obtain a clearer positioning and a stronger hand feel, the rotational torque can be increased by increasing the contact cooperation between the elastic and retractable mechanism and the limiting structure in the circumferential direction.

[0037] In the embodiment disclosed in the present utility model, the limiting structure includes more than two limiting grooves 6 distributed around the inner wall of the sleeve 3, and the elastic-contracting mechanism is provided with an elastically retractable elastic member 7 and the elastic member 7 can be increased according to demand. For example, the elastic member 7 is symmetrically arranged at two locations, and the force is evenly applied and the force is better. The elastic member 7 cooperates with the limiting groove 6 to limit the rotation of the handle 2, and the rotation positioning of the handle 2 when rotating is achieved through the concave-convex cooperation, so that the user can clearly know that the handle 2 is rotated into place and unlocked or locked. In the unlocked or locked state, the two elastic members 7 cooperate with the two limiting grooves 6 to bring greater torque to the handle 2, so as to avoid the handle 2 from easily rotating due to factors such as gravity or slight touch and losing the current state, which is more conducive to the user's next use operation. Figure 3 or Figure 8As shown, there are four limiting grooves 6 evenly distributed around the inner wall of the sleeve 3, so that the handle 2 can trigger the cooperation of the elastic contraction mechanism and the limiting structure when it is turned left or right, making the installation adaptability of the utility model higher. Furthermore, on the basis of the four limiting grooves 6, small grooves (not shown in the figure) can be further added between each limiting groove 6, but the depth of the small grooves will be shallower than that of the limiting grooves 6, and the elastic member 7 will bring a good operating feel to the user when passing through these small grooves. The elastic member 7 can be implemented in two ways: marbles or shrapnel. The utility model preferably adopts the marble solution, which can roll out of the limiting groove 6 by the marble, making the user's operation more labor-saving.

[0038] The rotating shaft 5 and the sleeve cavity 4 of the utility model can be arranged in an integrated or split disassembly scheme:

[0039] like Figures 2 to 4 In the first embodiment shown, the rotating shaft 5 is integrally arranged in the sleeve cavity 4. At this time, the rotating shaft 5 includes a transmission hole 52 for the transmission shaft 8 to be inserted. One end of the transmission shaft 8 is installed with an elastic-retracting mechanism, and the elastic-retracting mechanism is inserted into the transmission hole 52 to realize the arrangement of the elastic-retracting mechanism on the rotating shaft 5. The side wall of the transmission hole 52 is provided with an avoidance groove 53 for the elastic-retracting mechanism to pass out and cooperate with the limiting structure. The arrangement of the elastic-retracting mechanism using the transmission shaft 8 can make the arrangement structure of the elastic-retracting mechanism simpler and more conducive to the assembly and arrangement of the elastic-retracting mechanism; and the other end of the transmission shaft 8 is connected to the lock body in the window door, and the lock body in the window door can be driven to work by rotating the handle 2 to realize the locking or unlocking of the window door.

[0040] As a preferred solution of the first embodiment, the side wall of the bottom end of the rotating shaft 5 is provided with a retaining spring groove 59 and passes through the sleeve 3 to the bottom of the sleeve 3. The retaining spring groove 59 is clamped in the retaining spring 91 and the bottom end of the rotating shaft 5 is clamped at the bottom of the sleeve 3 through the retaining spring 91, so that the handle 2 can be fixed relative to the axial direction of the sleeve 3.

[0041] like Figures 5 to 8The second embodiment shown is based on the first embodiment and transforms the rotating shaft 5 into a detachable separation structure relative to the sleeve cavity 4. At this time, the rotating shaft 5 has a transmission hole 52 and an avoidance groove 53, which can be detachably installed with the sleeve cavity. A mounting hole 54 is provided on the top of the rotating shaft 5, and a threaded hole 41 is provided on the top wall of the sleeve cavity 4 corresponding to the mounting hole 54. The rotating shaft 5 passes through the sleeve 3 and is installed in the sleeve cavity 4. The screw 92 is installed in the transmission hole 52 and passes through the mounting hole 54 to connect with the threaded hole 41 to fix the rotating shaft 5 in the sleeve cavity 4, and a bending portion 51 is provided at the end of the rotating shaft 5. After the rotating shaft 5 passes through the bottom opening of the sleeve 3 in turn, it is bent outwardly through the bending portion 51 and abuts against the bottom of the sleeve 3, and a gasket is sandwiched between the bending portion 51 and the bottom of the sleeve 3, so that the handle 2 can be fixed relative to the axial direction of the sleeve 3, and at the same time, the assembly of the handle 2 and the mounting base 1 is realized, making the assembly connection between the handle 2 and the mounting base 1 more convenient. In addition, the detachably mounted rotating shaft 5 is used to process and assemble the small component module, so that the processing procedure can be simplified and is beneficial to the processing and production of the handle 2.

[0042] As a preferred scheme of the second embodiment, a limit platform 55 is provided on the top of the rotating shaft 5, and a limit groove 42 is provided on the top wall of the sleeve cavity 4 for the limit platform 55 to be embedded in. The circumferential shape of the limit platform 55 can be square or elliptical, etc. The axial shape of the inner wall of the sleeve cavity 4 matches the limit platform 55. When the limit platform 55 is embedded in the limit groove 42, the rotating shaft 5 and the sleeve cavity 4 can be relatively circumferentially positioned and cannot rotate; the mounting hole 54 passes through the limit platform 55, and the threaded hole 41 is arranged in the limit groove 42. When the rotating shaft 5 is connected and fixed to the sleeve cavity 4 by the screw 92 through the mounting hole 54 and the threaded hole 41, the limit platform 55 is also embedded in the limit groove 42 to achieve circumferential positioning, so that the handle 2 can drive the rotating shaft 5 more stably and better drive the transmission shaft 8 and the retractable mechanism to work.

[0043] like Figures 9 to 13 The third embodiment shown also adopts a solution in which the rotating shaft 5 and the sleeve cavity 4 are detachably separated. However, unlike the first and second embodiments, the rotating shaft 5 directly integrates the retractable mechanism inside the rotating shaft 5 by providing an installation cavity 56, thereby forming a modular connecting component, which makes it more convenient to realize the rotation installation of the handle 2. The side wall of the installation cavity 56 is provided with an avoidance hole 57 for the retractable mechanism to pass through and cooperate with the limiting structure.

[0044] Since the elastic and retractable mechanism is directly arranged in the rotating shaft 5, the method and mechanism arrangement of the handle to lock the window or door become more flexible. For example, a simple locking handle (such as a handle that locks the window frame or door frame by a tongue) Fig.15 As shown), on the basis of the third embodiment, a latch tongue 21 is directly added to the handle 2, and the arrangement of the locking handle can be realized by rotating the handle 2 to drive the latch tongue 21 to move and lock the window frame or leave the window frame to unlock.

[0045] Of course, the third embodiment preferably adopts a solution of a transmission handle that is transmission-connected between the transmission shaft and the lock body inside the window or door, and it is only necessary to transform the bottom opening of the installation cavity 56 into a transmission hole that is transmission-connected with the transmission shaft.

[0046] As a preferred solution of the third embodiment, a fixing hole 43 is penetrated through the side wall of the sleeve cavity 4, and a limiting hole 58 matching the fixing hole 43 is provided on the top of the rotating shaft 5. The fixing screw 93 passes through the fixing hole 43 and is inserted into the limiting hole 58 to limit and fix the rotating shaft 5 in the sleeve cavity 4, and a bending portion 51 is provided at the end of the rotating shaft 5. After the rotating shaft 5 passes through the bottom opening of the sleeve 3 in turn, it is bent outwardly through the bending portion 51 to abut against the bottom of the sleeve 3, and a gasket is sandwiched between the bending portion 51 and the bottom of the sleeve 3, so that the handle 2 can be fixed relative to the axial direction of the sleeve 3 to realize the assembly of the handle 2 and the mounting base 1. Furthermore, a limit platform 55 is provided on the top of the rotating shaft 5, and a limit groove 42 is provided on the top wall of the sleeve cavity 4 for the limit platform 55 to be embedded in. The limit platform 55 is embedded in the limit groove 42 to position the rotating shaft 5 relative to the sleeve cavity 4 in the circumferential direction; the limit hole 58 is located on the side of the limit platform 55, that is, when the rotating shaft 5 is fixed in the sleeve cavity 4 by the set screw 93, the limit platform 55 is also embedded in the limit groove 42 to achieve circumferential positioning, so that the rotating shaft 5 can be driven by the handle 2 more stably and better drive the elastic retraction mechanism to work.

[0047] As a fourth embodiment of the present utility model, Fig.14 As shown, based on the third embodiment, the rotating shaft 5 with the mounting cavity 56 is integrally arranged in the sleeve cavity 4 , and the elastic-retracting mechanism is arranged in the mounting cavity 56 .
