[0002] This section provides only background information related to this application to enable those skilled in the art to understand this application more thoroughly and accurately, and it is not necessarily prior art.

[0003] In traditional door and window handles, the exposed mounting holes inside the handle base are unsightly. To address this issue, decorative covers are installed on the surface of the handle base to conceal them. Currently, most decorative covers are decorative screw caps, meaning they have a through hole in the center through which the handle passes. A magnetic closure is used between the decorative screw cap and the mounting base for fixation. Thus, when the user moves the decorative screw cap to disengage the magnetic closure, the through hole in the decorative screw cap can rotate around the handle, exposing multiple mounting holes on the handle base, allowing for screw removal.

[0004] However, the use of decorative caps has the following problems: First, since the decorative cap is fixed to the mounting base by a magnetic assemblies, the decorative cap is prone to swaying under force and causing the magnetic assemblies to detach, resulting in poor assembly stability; Second, during the decoration process, the surface of the decorative cap is easily scratched, and when the decorative cap needs to be removed, the entire mounting base needs to be disassembled, which is cumbersome and inefficient.

Therefore, they should not be construed as limitations on this utility model.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] Example 1 See Figures 1-4 This utility model first provides an assembly structure for a handle decorative cover, including a handle base 1, on which a handle 2 is provided; wherein, the surface of the handle base 1 is also provided with a decorative cover 3, and the decorative cover 3 has an opening for a clearance position 31 for avoiding the handle 2, that is, the installation and removal of the decorative cover 3 and the installation and removal of the handle 2 can be realized separately; wherein, the decorative cover 3 is provided with a first elastic locking structure 4, and the handle base 1 is provided with a first locking position 14, and the decorative cover 3 is detachably locked onto the handle base 1 by the locking cooperation between the first elastic locking structure 4 and the first locking position 14.

[0023] Therefore, by setting a first elastic locking structure 4 on the decorative cover 3 and engaging it with the first locking position 14 on the handle seat 1, the assembly firmness of the decorative cover 3 can be guaranteed, preventing it from swaying under force. In addition, the decorative cover 3 is detachably locked to the handle seat 1 through the first elastic locking structure 4. When the surface of the decorative cover 3 is scratched, the decorative cover 3 can be removed from the handle seat 1 separately, which is simple to operate and more efficient.

[0024] Specifically, the first elastic locking structure 4 includes a first base 41, a first locking member 42, and a first elastic member 43. The first base 41 is fixed to the decorative cover 3. Preferably, the decorative cover 3 has a mounting step 32 at its bottom, and the first base 41 is mounted on the mounting step 32. The first elastic member 43 and the first locking member 42 are both disposed within the first base 41, and the first locking member 42 and the first elastic member 43 abut against each other. Under the elastic force of the first elastic member 43, the first locking member 42 partially protrudes from the first base 41. Preferably, the first locking member 42 is a first ball, and the first elastic member 43 is a first return spring, with one end of the first return spring abutting against the first ball.

[0025] In addition, the handle seat 1 is provided with a first slot 11 that connects to the first locking position 14. When the decorative cover 3 is placed on the handle seat 1, the first seat body 41 extends into the first slot 11. At this time, the inner wall of the first slot 11 abuts against and compresses the first ball. Then, the decorative cover 3 is pressed until the first ball connects with the first locking position 14. At this time, the first ball is reset and extended under the action of the first return spring and engages with the first locking position 14, thereby realizing the assembly of the decorative cover 3 onto the handle seat 1.

[0026] Preferably, the first locking position 14 is a sloping groove that connects to the bottom edge of the first locking slot 11, and the first ball can abut against the sloping groove to achieve positioning and fixation.

[0027] It should be noted that when it is necessary to remove the decorative cover 3 from the handle seat 1, simply pry the decorative cover 3 outward until the first ball is disengaged from the first locking position 14, at which point the decorative cover 3 can be removed from the handle seat 1, which is convenient to operate.

[0028] In this embodiment of the utility model, the first elastic clamping structure 4 is provided in two sets and is respectively provided on the upper and lower sides of the decorative cover 3. The first slot 11 and the first slot 14 are also provided in two sets and are corresponding to the first elastic clamping structure 4.

[0029] Therefore, by setting two sets of first elastic clamping structures 4, the assembly firmness of the decorative cover 3 can be further improved, ensuring that it does not deflect.

[0030] In addition, the upper and lower sides of the handle seat 1 are provided with two mounting holes 13 that are respectively connected to the two first slots 11. The handle seat 1 can be installed on the door body through the two mounting holes 13. When the decorative cover 3 is placed on the handle seat 1, it can be used to cover the two mounting holes 13, so that the door and window handle is more concise and beautiful.

[0031] Example 2 See Figures 1-7 The second aspect of this utility model also provides a door and window handle, including the assembly structure of the above embodiment one and a transmission component 5. The transmission component 5 is disposed inside the handle seat 1, and the handle 2 is connected to the transmission component 5 in a transmission manner.

[0032] In this embodiment of the utility model, a bottom cover 8 is also included. The handle seat 1 has an open mounting cavity inside. The bottom cover 8 is placed on the bottom of the handle seat 1 and covers the cavity. The transmission component 5 is disposed in the mounting cavity.

[0033] Specifically, the transmission assembly 5 includes a driving gear 51, a driven gear 52, and a transmission gear 53, all of which are rotatably mounted inside the handle seat 1. Preferably, it also includes a gear plate 54 fixedly mounted inside the mounting cavity of the handle seat 1, on which the driving gear 51, driven gear 52, and transmission gear 53 are rotatably mounted. The driving gear 51 and driven gear 52 are spaced apart, with the driving gear 51 connected to the handle 2 and the driven gear 51 connected to the output shaft (not shown in the figure). The transmission gear 53 is located on one side of the driving gear 51 and the driven gear 52, and meshes with both the driving gear 51 and the driven gear 52.

[0034] Therefore, when the handle 2 is rotated, the drive gear 51 can be rotated, which in turn drives the transmission gear 53 and the driven gear 52 to rotate, and finally drives the output shaft to rotate. After the output shaft rotates, it can drive the hardware in the transmission lock box to move, thereby realizing locking or unlocking.

[0035] See Figure 6 It also includes a locking assembly 6, which includes a lever 61 slidably mounted on the handle base 1 and a locking member 62 mounted on the lever 61. When the lever 61 is moved, the locking member 62 can be moved, and after moving, the locking member 62 can engage or disengage with the locking teeth on the transmission gear 53 to lock or release the handle 2. Preferably, the locking member 62 is a locking plate.

[0036] See Figure 7It also includes a positioning component 7, which includes a cam 71 disposed within the handle seat 1 and a second elastic locking structure 72. Specifically, the handle seat 1 has a second base 12, and the second elastic locking structure 72 includes a second locking member 721 and a second elastic member 722 disposed within the second base 12. The second locking member 721 and the second elastic member 722 abut against each other. Under the elastic force of the second elastic member 722, the second locking member 721 partially extends out of the second base 12. The cam 71 is connected to the handle 2, and the edge of the cam 71 has several second locking positions 711 along the circumferential direction. The second locking member 721 is locked into the second locking positions 711 to achieve positioning of the handle 2. Preferably, the second locking member 721 is a second ball, and the second elastic member 722 is a second return spring.

[0037] Therefore, in actual use, the handle 2 generally has multiple operating positions. In a certain operating position, the hardware connected to the transmission lock box can move a certain distance. Therefore, by setting the positioning component 7, it is possible to ensure that the handle 2 is accurately positioned in a certain operating position, which is convenient for user operation.

[0038] Preferably, the second locking position 711 is a slot formed at the edge of the cam 71, and four slots are provided and evenly spaced along the circumference on the cam 71; two second elastic locking structures 72 are provided, and the two second elastic locking structures 72 are set at a 90-degree angle. It can be understood that, under normal circumstances, existing door and window handles usually have four positions: vertically upward, vertically downward, horizontally to the left, and horizontally to the right. Therefore, this application can better meet the usage requirements by providing four second locking positions 711.

[0039] Meanwhile, in order to improve the stability of the positioning of the handle 2, this application provides two second elastic locking structures 72, which are respectively inserted into two slots by two second balls to achieve locking and fixing, thereby preventing the cam 71 from rotating and thus preventing the handle 2 from rotating.

[0040] Of course, it should be noted that in other embodiments, the number and distribution of the second locking position 711 and the second elastic locking structure 72 can be selected according to actual needs, and are not limited to the above description.

[0041] In addition, it also includes a locking screw 9, which passes through the drive gear 51 and the cam 71 in sequence and connects and fixes them to the handle 2, so that when the handle 2 is rotated, the drive gear 51 and the cam 71 can be rotated synchronously.

[0042] In summary, the assembly structure of the decorative cover and the door / window handle provided by this utility model, by setting a first elastic locking structure 4 on the decorative cover 3 and engaging it with the first locking position 14 on the handle seat, can ensure the assembly firmness of the decorative cover 3 and prevent it from swaying under force. In addition, the decorative cover 3 is detachably locked to the handle seat 1 through the first elastic locking structure 4. When the surface of the decorative cover 3 is scratched, the decorative cover 3 can be removed from the handle seat 1 separately, which is simple to operate and more efficient.

[0043] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on the other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to the other component.

[0044] It should be understood that the terms "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
