[0056] The present application is described in detail below in conjunction with the accompanying drawings:

[0057] According to some embodiments of the present application, Figure 1-5 As shown in the combination, the handle includes a fixed seat 1 and a rotating member 2; the fixed seat 1 includes a seat body 11 and a plurality of holding components 12; a first through hole A1 and a plurality of limiting channels B are provided on the seat body 11; the plurality of limiting channels B are arranged at intervals along the circumference of the first through hole A1, and the first through hole A1 can be arranged at the intersection of the extension direction of the limiting channel B, or the extension direction of the limiting channel B and the through hole extension direction of the first through hole A1 can be arranged vertically; one end of the limiting channel B passes through the hole wall of the first through hole A1, and the limiting channel B can be connected to the first through hole A1; as shown in FIG. Figure 3-4 As shown, multiple pressing components 12 are arranged in one-to-one correspondence with multiple limiting channels B. The pressing component 12 can be arranged in the limiting channel B. The pressing component 12 includes an elastic member 122 and a pressing member 121. The elastic member 122 is elastically matched between the pressing member 121 and the inner wall of the corresponding limiting channel B. Here, the inner wall of the limiting channel B can be an inner wall of the limiting channel B away from the first through hole A1. One end of the elastic member 122 can be abutted against the inner wall of the limiting channel B, and the other end can be elastically acted on the pressing member 121; part of the pressing member 121 or the entire pressing member 121 can be arranged in the first through hole A1.

[0058] The rotating member 2 includes a main body 21 and a limiting portion 22 arranged on the side of the main body 21. The limiting portion 22 can be an outer edge arranged on the side of the main body 21; the main body 21 can be rotatably inserted in the first through hole A1, and the main body 21 can be rotatably arranged relative to the first through hole A1 of the seat body 11 and inserted in the first through hole A1; at least part of the limiting portion 22 is located in the first through hole A1, and at least part of it can be part of the limiting portion 22 or the entire limiting portion 22 can be arranged in the first through hole A1, as long as the limiting portion 22 and the holding member 1 are realized 21 can be abutted against each other; a plurality of recessed structures are arranged at intervals on the circumferential side of the limiting portion 22, and the intervals can be a gap between two adjacent recessed structures, or the two recessed structures are connected by a surface, which is not limited here; the plurality of recessed structures include a first recessed structure 221 and a second recessed structure 222, the opening of the first recessed structure 221 is larger than the opening of the second recessed structure 222, and the concave opening of the first recessed structure 221 away from the first through hole A1 can be larger than the concave opening of the second recessed structure 222 away from the first through hole A1.

[0059] In the process of the main body 21 rotating relative to the seat body 11, the main body 21 has a first rotation position and a second rotation position. The first rotation position can be a position where the holding member 121 abuts against the first recessed structure 221, and the second rotation position can be a position where the holding member 121 abuts against the second recessed structure 222. When the main body 21 is located at the first rotation position, at least one holding member 121 can slide into the first recessed structure 221 in response to the elastic force of the elastic member 122 to limit the rotation of the rotating member 2. Limiting the rotation of the rotating member 2 can be understood as follows: no additional rotational force is applied to the main body 21, and the holding member 121 is pressed. 121 can be in the first recessed structure 221; when additional rotational force is applied, the holding member 121 can slide out of the first recessed structure 221; the main body 21 is located at the second rotation position, and at least one holding member 121 can slide into the second recessed structure 222 in response to the elastic force of the elastic member 122, so that the holding member 121 collides with the inner wall of the second recessed structure 222 and makes a sound. The collision sound can be understood as the holding member 121 and the second recessed structure 222 can be made of metal, and a sound can be made when the two collide relative to each other. Specifically, the metal material can be iron, steel or alloy and other metal materials, which are not limited here.

[0060] In this application, the functions of each component are:

[0061] The fixed seat 1 is used to be fixedly connected with the window sash (existing technology) so that the rotating member 2 can rotate relative to the fixed seat 1; the seat body 11 is used to provide an installation space for the limit channel B; the pressing component 12 is used so that when the rotating member 2 rotates relative to the seat body 11, the pressing member 121 in the pressing component 12 can be elastically matched with the limit portion 22, thereby limiting the rotation of the rotating member 2 or making the handle sound; the limit channel B is used to provide an accommodating space or the limit channel B to place the pressing component 12; the first through hole A1 is used to provide a rotation space for the rotating member 2; the elastic member 122 is used to provide an elastic force for the pressing member 121; the pressing member 121 is used to elastically match with the first recessed structure 221 to limit the rotation of the rotating member 2, or elastically match with the second recessed structure 221 The recessed structure 222 causes the holding member 121 to collide with the inner wall of the second recessed structure 222 and make a sound; the rotating member 2 is rotatably matched with the seat body 11; the main body 21 is used to provide an installation space for the limiting portion 22; the limiting portion 22 is used to provide an installation space for the recessed structure and to rotatably match with the holding member 121; the recessed structure is used to provide an abutment surface in cooperation with the holding member 121, and can enable the handle to limit the rotation of the rotating member 2 or the handle to make a sound; the first recessed structure 221 is used to elastically abut against the holding member 121 to limit the rotation of the rotating member 2; the second recessed structure 222 is used to elastically abut against the holding member 121 to achieve a collision between the holding member 121 and the inner wall of the second recessed structure 222 and make a sound.

[0062] Specifically, the fixed seat 1 can be fixedly connected to the window sash (the window sash is the opening sash on the door and window, and a lock box can be installed in the window sash). The fixed seat 1 includes a seat body 11 and a plurality of holding components 12. The seat body 11 is provided with a first through hole A1 and a plurality of limiting channels B. The plurality of limiting channels B are arranged at circumferential intervals along the first through hole A1. One end of the limiting channel B passes through the hole wall of the first through hole A1, that is, the limiting channel B is connected to the first through hole A1, and the main body 21 is rotatably inserted into the first through hole A1.

[0063] It can be understood that when the main body 21 rotates relative to the seat body 11, the limiting portion 22 located on the side of the main body 21 can be driven to rotate. Since the elastic member 122 is elastically matched between the holding member 121 and the inner wall of the corresponding limiting channel B, the first recessed structure 221 or the second recessed structure 222 of the limiting portion 22 can be in elastic contact with the holding member 121. In other words, the main body 21 and the holding member 121 can have a first rotation position or a second rotation position in the rotational cooperation; when the main body 21 is in the first rotation position, since the opening of the first recessed structure 221 is larger than the opening of the second recessed structure 222, the limiting portion 22 can be in elastic contact with the holding member 121. The recessed structure 222 has an opening; at least one pressing member 121 can slide into the first recessed structure 221 in response to the elastic force of the elastic member 122, so that the pressing member 121 has a sufficient abutment surface at the first rotation position to limit the rotation of the rotating member 2; when the main body 21 is located at the second rotation position, at least one pressing member 121 can slide into the second recessed structure 222 in response to the elastic force of the elastic member 122. Since the pressing member 121 and the second recessed structure 222 can be made of metal, the pressing member 121 and the inner wall of the second recessed structure 222 produce a metal collision and make a sound.

[0064] In the existing structure of this field:

[0065] 1: The handle structure is usually provided with a gasket that can be locked at the upper end of the seat body 11 (in the prior art, the gasket is provided with a bead hole, which is used to lock with the holding component 12) and the holding component 12; the gasket is provided with a bead hole for the holding member 121 to abut against; the installation direction of the holding component 12 on the seat body 11 is the same as the extension direction of the rotation axis of the rotating member 2 (that is, the holding component 12 is vertically arranged along the seat body 11); the bead hole and the holding member 121 are locked; in this technology, there are obvious defects, because the holding component The installation direction of 12 is the same as the extension direction of the rotation axis of the rotating part 2. The following problems exist in the setting of the gasket and the seat body 11: 1) The direct distance between the gasket and the seat body 11 is too large, which will cause the inability to lock or make sounds; 2) The distance between the gasket and the seat body 11 is too small, which will cause the holding part 121 and the bead hole to be stuck, making the product handle unable to rotate. Therefore, in the assembly of the handle, the installer needs to control the distance between the gasket and the seat body 11 during installation so that it can be used normally, which makes the installation efficiency low.

[0066] 2: In combination with the above-mentioned existing structure, it also includes a wheel seat (with the function of clamping the gasket), and a groove is provided on the wheel seat to cooperate with the bead hole of the gasket. The wheel seat is clamped and matched with the gasket. The wheel seat is configured to rotate under the control of the rotating member 2. Due to the arrangement of the wheel seat and the gasket, during the force transmission process, it is necessary to sequentially go through the rotating member 2-wheel seat-gasket-pressing assembly 12, so there is a loss of force in the transmission.

[0067] Therefore, the inventors of the present application found that: the gasket with a bead-locking hole was eliminated (the prior art, which serves as a locking position), the structure of the rotating part 2 was improved (a groove structure was provided on the rotating part 2), and the installation positions of the holding assembly 12 and the rotating part 2 were changed (placed horizontally); in terms of the force, the rotating part 2 and the holding assembly 12 were directly matched and rotated, which improved the loss of force during the rotation of the rotating part 2, and since the gasket with the bead-locking hole (the prior art) was reduced, the transmission was more efficient.

[0068] When installing the handle, the inventor arranges the pressing component 12 horizontally on the base 11, eliminates the gasket with the bead hole (existing technology), and provides the rotating part 2 with a recessed structure; so that during the rotation of the rotating part 2, the recessed structure can abut and cooperate with the pressing component 121; therefore, the installer does not need to consider the size of the matching clearance between the gasket with the bead hole (existing technology) and the rotating part 2, and can efficiently install the handle, thereby improving the installation efficiency of the handle.

[0069] Exemplarily, the fixing seat 1 can be fixedly connected to the window sash by threaded connection, snap connection or other detachable fixed connection; through this arrangement, the stability of the rotation of the rotating member 2 relative to the fixing seat 1 is improved.

[0070] Exemplarily, the channel extension direction of the multiple limit channels B can be intersecting with the axial direction of the first through hole A1; through this arrangement, the holding assembly 12 can better rotate and align with the recessed structure on the rotating part 2, thereby improving the user's feel.

[0071] Exemplarily, there can be four limiting channels B; through this arrangement, four pressing assemblies 12 can be provided, and the pressing assemblies 12 are installed one by one in the limiting channels B; during the rotating part 2, the four recessed structures can be simultaneously matched with the pressing part 121, thereby improving the problem that the pressing part 121 cannot align with the recessed structure due to excessive rotational force, thereby improving safety.

[0072] Exemplarily, the limiting channel B can be distributed in the seat body 11 in a cross shape and connected to the first through hole A1; through this arrangement, at least part of the holding member 121 can be located in the first through hole A1 and rotated with the recessed structure, thereby improving the uniform distribution of the force of the rotating member 2 during rotation and enhancing the feel of use.

[0073] Exemplarily, the limiting channel B can be a blind hole, a tapered hole, or a protrusion installed in the hole channel. The protrusion only needs to limit one end of the elastic member 122. Through this setting, the elastic member 122 can apply elastic force to the pressing member 121 and improve the stability of the pressing member 121 when it is in action.

[0074] Exemplarily, the elastic member 122 may be a compression spring, a tension spring, or a torsion spring; this configuration provides an elastic force to the pressing member 121 so that the pressing member 121 can return to its original position and abut against the pressing member 121 during operation.

[0075] Exemplarily, the holding member 121 can be a round ball, a steel ball or a rolling ball. Through this arrangement, when the limiting portion 22 of the rotating member 2 rotates, the arc surface at one end of the holding member 121 can smoothly transition from the first recessed structure 221 to the second recessed structure 222, thereby improving the continuity of the force when the rotating member 2 rotates.

[0076] Exemplarily, the rotating member 2 may be a rotating column, a rotating shaft or a rotating rod; through this arrangement, the rotating member 2 may save space and improve the compactness of the product.

[0077] Exemplarily, the limiting portion 22 can be formed as a protrusion or a recessed portion arranged on the side of the main body 21, as long as it can be elastically abutted with the holding piece 121; through this arrangement, the gasket with the bead hole is saved, making the force transmission when the handle is rotated more efficient.

[0078] Exemplarily, the first recessed structure 221 may be a concave groove or an arc-shaped concave surface; through this arrangement, the arc-shaped surface at one end of the holding member 121 can smoothly transition from the first recessed structure 221 to the second recessed structure 222, thereby improving the continuity of the force when the rotating member 2 rotates.

[0079] Exemplarily, the second recessed structure 222 may be a concave groove or an arc-shaped concave surface; through this arrangement, the arc-shaped surface at one end of the holding member 121 can smoothly transition from the second recessed structure 222 to the first recessed structure 221, thereby improving the continuity of the force when the rotating member 2 rotates.

[0080] Exemplarily, the opening of the first recessed structure 221 can be a concave opening of the first recessed structure 221 away from the first through hole A1; through this arrangement, the first recessed structure 221 is relatively close to the holding member 121, thereby improving the rationality of the structure of the present application.

[0081] Exemplarily, the opening of the second recessed structure 222 can be a concave opening of the second recessed structure 222 away from the first through hole A1; through this arrangement, the second recessed structure 222 is relatively close to the holding member 121, thereby improving the rationality of the structure of the present application.

[0082] Exemplarily, at least one pressing member 121 can be one or more pressing members; it is understandable that, according to actual use requirements, when different recessed depths of the first recessed structure 221 or the second recessed structure 222 are configured, the contact area between the pressing member 121 and the recessed structure will be different during the rotation of the rotating member 2. Different numbers of pressing members 121 can be configured according to actual needs, thereby improving the rationality of the structure of the present application.

[0083] In some embodiments, Figure 1-5 As shown in the figure, there are multiple first recessed structures 221 and multiple second recessed structures 222 . Along the circumference of the limiting portion 22 , a second recessed structure 222 is provided between every two adjacent first recessed structures 221 .

[0084] Specifically, a plurality of first recessed structures 221 and a plurality of second recessed structures 222 may be provided on the limiting portion 22 of the rotating member 2; through this arrangement, when the user rotates the rotating member 2, the user can switch between different states of limiting the rotation effect of the rotating member 2 and the handle sounding effect, for example: in the process of the pressing member 121 transitioning from the first recessed structure 221 to the second recessed structure 222, it is necessary to apply additional rotational force so that the pressing member 121 can reach the second recessed structure 222; in the process of the pressing member 121 transitioning from the second recessed structure 222 to the first recessed structure 221, the rotational force can be reduced so that the pressing member 121 can reach the position of the first recessed structure 221, and so on; through this arrangement, the user experience is improved.

[0085] Along the circumference of the limiting portion 22, a second recessed structure 222 is provided between every two adjacent first recessed structures 221. Through this arrangement, when the user rotates the rotating part 2, the user can regularly identify whether the door or window is locked by the sound pattern, thereby improving safety.

[0086] Exemplarily, there are multiple first recessed structures 221, which may be 2 or more. Through this arrangement, during the rotation of the rotating member 2, multiple first recessed structures 221 can abut and cooperate with multiple pressing members 121, thereby improving the problem that the pressing members 121 cannot align with the first recessed structure 221 due to the concave surface of the first recessed structure 221 being too flat, thereby improving stability.

[0087] Exemplarily, the second recessed structure 222 is provided in plurality and may be 2 or more; through this arrangement, during the rotation of the rotating member 2, the plurality of second recessed structures 222 can abut and cooperate with the plurality of pressing members 121, thereby improving the problem that the pressing members 121 cannot align with the second recessed structure 222 due to the concave surface of the second recessed structure 222 being too flat, thereby improving stability.

[0088] Exemplarily, four first recessed structures 221 may be provided; through this arrangement, four holding components 12 may be provided, and during the rotation of the rotating member 2, the four first recessed structures 221 may abut against the four holding members 121, thereby increasing the abutment area and improving the stability of the handle when in use.

[0089] Exemplarily, there may be four or eight second recessed structures 222. Through this arrangement, four pressing assemblies 12 may be provided. During the rotation of the rotating member 2, the four second recessed structures 222 may abut against the four pressing members 121; or, the four pressing members 121 may abut against four of the eight second recessed structures 222, thereby increasing the abutment area and improving the stability of the handle when in use.

[0090] Exemplarily, the sound may be produced due to the collision between the pressing member 121 and the second recessed structure 222, which are made of metal. The metal material may be iron, steel or alloy, which is not limited here.

[0091] In some embodiments, Figure 1-5 As shown in the combination, all the first recessed structures 221 are arranged at equal intervals along the circumference of the limiting portion 22. Through this arrangement, the interval arrangement can provide relative rotation space from each first recessed structure 221 to the second recessed structure 222, so that when a user rotates the rotating part 2, the pressing part 121 can be regularly located in turn to determine whether it falls into the position of each first recessed structure 221, and the rotation of the rotating part 2 can be limited.

[0092] like Figure 4 As shown, along the circumference of the limiting portion 22, a plurality of second recessed structures 222 located between two adjacent first recessed structures 221 constitute a second recessed structure group L; each second recessed structure group L is configured to have the same number of second recessed structures 222; in the same second recessed structure group L, there is a first interval between every two adjacent second recessed structures 222; and / or, the holding assembly 12 is provided with four groups, and four first recessed structures 221 are provided.

[0093] Specifically, two adjacent first recessed structures 221 may be provided with two or more second recessed structures 222, and two or more second recessed structures 222 may be defined as a second recessed structure group L. Each second recessed structure group L located in the limiting portion 22 may be the same, and there may be a first interval between two adjacent second recessed structures 222. Through this arrangement, the user's operating error caused by the first recessed structure 221 and the second recessed structure 222 being too close in position is improved.

[0094] The first spacing function can provide a relative rotation space between each second recessed structure 222 and the first recessed structure 221, thereby improving the possibility of user operation errors caused by the first recessed structure 221 and the second recessed structure 222 being too close to each other; operation errors can be that the pressing member 121 is actually in the first recessed structure 221 but is misunderstood as being in the second recessed structure 222, or that the pressing member 121 is actually in the second recessed structure 222 but is misunderstood as being in the first recessed structure 221. This arrangement improves the accuracy of unlocking or locking operations and enhances safety.

[0095] like Figure 4 As shown, exemplarily, each pressing component 12 includes an elastic member 122 and a pressing member 121, and four first recessed structures 221 may be provided, and adjacent first recessed structures 221 may be distributed on the limiting portion 22 at an angle of 90°; through this arrangement, when the user is unable to determine whether the pressing member 121 slides into the first recessed structure 221, the user can identify and judge whether the pressing member 121 falls into the first recessed structure 221 or the second recessed structure 222 by the angle at which the rotating member 2 has been rotated, thereby improving the convenience of the user.

[0096] Exemplarily, the first interval may be a transition of a surface or a gap setting, through which the user's operation error caused by the first recessed structure 221 and the second recessed structure 222 being too close to each other is improved.

[0097] Exemplarily, the pressing assembly 12 can be provided with four groups, and the first recessed structures 221 can be provided with four, and the four pressing members 121 fall into the four first recessed structures 221 respectively; through this arrangement, when the rotating member 2 is rotated, the four pressing members 121 located on the seat body 11 can simultaneously fall into the four first recessed structures 221 located on the limiting part 22, thereby increasing the user's feel or experience.

[0098] Exemplarily, the pressing assembly 12 can be provided with four groups, and the second recessed structures 222 can be provided with four, and the four pressing members 121 fall into the four second recessed structures 222 respectively. Through this arrangement, when the rotating member 2 is rotated, the four pressing members 121 located on the seat body 11 can simultaneously fall into the four second recessed structures 222 of the limiting portion 22, thereby increasing the user's feel or experience.

[0099] In some embodiments, Figure 1-5 As shown in the figure, the limiting portion 22 has a plurality of first surfaces C located on the circumferential side of the limiting portion 22 , the first surfaces C are recessed toward the central axis of the limiting portion 22 and define a recessed structure, and the first surfaces C are constructed as arc-shaped surfaces.

[0100] like Figure 1-5 As shown in combination, specifically, a plurality of first surfaces C may be provided on the circumferential side of the limiting portion 22, and the first surface C is provided with a recessed structure, and the recessed inner surface of the recessed structure may be provided away from the central axis direction of the limiting portion 22, that is, the recessed opening portion is provided away from the central axis direction of the limiting portion 22; it can be understood that the first surface C may be a single first surface C1, or a surface connected by the first surface C1 and the second surface C2, or a recessed surface formed by connecting the first surface C1, the second surface C2 and the third surface C3, which is not limited here; by setting the first surface C as a recessed structure, during the rotation of the limiting portion 22, the holding member 121 may slide from one of the first surfaces C of the limiting portion 22 into another adjacent first surface C, thereby improving the occurrence of jamming when the handle is rotated.

[0101] Exemplarily, the first surface C can be an arc surface setting, or a surface formed by connecting multiple surfaces; through this setting, the arc surface at one end of the holding member 121 can smoothly transition from the first surface C to another adjacent first surface C, thereby improving the continuity of the force when the rotating member 2 rotates.

[0102] Exemplarily, the multiple first surfaces C can be composed of 2 or more surfaces; through this arrangement, the multiple first surfaces C can be evenly distributed on the circumferential side of the rotating part 2, making it smoother for the user to operate the rotating part 2 in circumferential rotation, thereby improving the user experience.

[0103] Exemplarily, the first surface C may be a vertical groove. By providing a vertical groove structure, the processing is convenient or the molding is rapid during processing, thereby improving the processing efficiency.

[0104] In some embodiments, Figure 2-5 As shown in combination, the area of ​​the first surface C defining the first recessed structure 221 is greater than the area of ​​the first surface C defining the second recessed structure 222; through this arrangement, since the area of ​​the first surface C of the first recessed structure 221 can be set to be greater than the area of ​​the first surface C of the second recessed structure, the holding member 121 can have a sufficient abutment surface with the first surface C of the first recessed structure 221, thereby limiting the rotation of the rotating member 2; when the holding member 121 slides into the first surface C of the second recessed structure 222, the handle can make a sound.

[0105] Exemplarily, the radius of curvature of the first surface C defining the first recessed structure 221 may be greater than the radius of curvature of the first surface C defining the second recessed structure 222. Through this arrangement, the holding member 121 may abut against the first surface C of the first recessed structure 221 to limit the rotation of the rotating member 2. When the holding member 121 slides into the area of ​​the first surface C of the second recessed structure 222, the handle may make a sound, thereby improving the rationality of the structure.

[0106] In some embodiments, Figure 2-5 As shown in the figure, the limiting portion 22 and the main body 21 are an integrally formed structure.

[0107] Specifically, the limiting portion 22 can be integrally formed with the main body 21, and the main body 21 can penetrate the limiting portion 22 along the central axis direction of the limiting portion 22. Through this arrangement, when the user rotates the main body 21, the limiting portion 22 can be directly driven to rotate, thereby realizing direct transmission of force and improving the rotation efficiency when the handle is in use.

[0108] In some embodiments, Figure 3-7 As shown in the combination, the handle also includes a handle 6; the main body 21 includes a first connection part 211 and a second connection part 212 connected to each other, and a limiting part 22 is provided on the surrounding side of the connection between the first connection part 211 and the second connection part 212; the first connection part 211 is connected to the handle 6, and the second connection part 212 is used to connect the lock box, and the first connection part 211 can drive the second connection part 212 to rotate in response to the force of the handle 6, thereby unlocking or locking the lock box.

[0109] The functions of the components in the handle are as follows: the handle 6 is used to facilitate the user to drive the rotating member 2 to rotate; the first connecting portion 211 is fixedly connected to the handle 6 to facilitate the transmission of the rotational force applied to the handle 6 to the rotating member 2 and drive the rotating member 2 to rotate; the second connecting portion 212 is used to connect the lock box (the lock box is a prior art that has the function of unlocking or locking doors and windows. The second connecting portion 212 here is connected to the lock box by direct connection or indirect connection with the aid of other connecting structures, such as a snap-fit, threaded connection or plug-in connection, which is not limited here).

[0110] like Figure 2-7 As shown in combination, specifically, by rotating the handle 6, the rotational force can pass through the handle 6-rotating member 2 (the first connecting portion 211, the limiting portion 22 and the second connecting portion 212)-lock box in sequence. Through this arrangement, the rotational force acting on the rotating member 2 can limit the rotation or sounding effect of the rotating member 2 when controlling the lock box, thereby reducing the force loss caused by too many handle parts and improving the stability of the handle.

[0111] In some embodiments, Figure 2-7 As shown in the figure, the seat body 11 may include a locking portion 13 disposed on the hole wall of the first through hole A1 ; at least a part of the limiting portion 22 is accommodated in the first through hole A1 and abuts against the locking portion 13 .

[0112] The functions of the components in the handle are as follows: the locking portion 13 is used to limit the limiting portion 22, so that the holding member 121 can be more accurately aligned with the first recessed structure 221 and the second recessed structure 222 of the limiting portion 22, and the occurrence of the rotating member 2 being disengaged from the first through hole A1 is improved; the exemplary locking portion 13 can be a circular protrusion set in the first through hole A1, and the locking portion 13 can have a hole set in the axial direction for the rotating member 2 to pass through.

[0113] Specifically, when installing the handle, the assembler only needs to abut the limiting portion 22 with the locking portion 13 to align the limiting portion 22 with the pressing member 121. Since the pressing assembly 12 is circumferentially distributed in the first through hole A1, the assembler does not need to consider the tightness of the matching between the limiting portion 22 and the pressing member 121, and can achieve quick installation.

[0114] When the user uses the product of the present application, since the locking portion 13 serves to limit the limiting portion 22 , the occurrence of the rotating member 2 being disengaged from the first through hole A1 is improved and the failure rate is reduced.

[0115] Exemplarily, a gasket (not shown) may be provided between the limiting portion 22 and the locking portion 13 , which reduces the friction coefficient between the limiting portion 22 and the locking portion 13 during rotation, thereby making the hand feel smoother.

[0116] In some embodiments, Figure 3-11 As shown in the figure, the handle further includes a gasket 3 and a connecting seat 4. The gasket 3 is arranged between the connecting seat 4 and the seat body 11. The gasket 3 is provided with a second through hole A2.

[0117] The connecting seat 4 is arranged on the side of the seat body 11 facing the first connecting part 211; the connecting seat 4 includes a accommodating groove 41 for accommodating lubricant, the opening of the accommodating groove 41 is arranged toward the seat body 11, and a third through hole A3 is provided on the connecting seat 4; the first connecting part 211 is inserted into the third through hole A3 via the first through hole A1 and the second through hole A2.

[0118] The functions of the components in the handle are as follows: the gasket 3 is used to reduce the friction between the seat body 11 and the connecting seat 4 during rotation, or can cooperate with the lubricant built into the connecting seat 4 or the seat body 11 during rotation, which can reduce the friction coefficient between the seat body 11 and the connecting seat 4 when used, and improve durability; the connecting seat 4 is used to connect the handle 6 and the rotating part 2; the accommodating groove 41 is used to accommodate or place the lubricant.

[0119] Specifically, the first connecting portion 211 of the rotating member 2 can be inserted or fixed to the third through hole A3 of the connecting seat 4 through the first through hole A1 of the seat body 11 and the second through hole A2 of the gasket 3. Figure 7-9As shown in combination, the first connecting portion 211 can be provided with a first mounting hole A4, and the first connecting portion 211 can be fixedly connected to the first mounting hole A4 located on the first connecting portion 211 via the first through hole A1, the second through hole A2, and the third through hole A3 and with the aid of a fastener 5 (which can be a bolt or a pin, etc.); the connecting seat 4 can be fixedly connected to the handle 6; the handle 6 can be provided with a second mounting hole A5 and a third mounting hole A6, wherein the central axis of the second mounting hole A5 can be parallel to or overlap with the central axis of the first through hole A1, the central axis of the second mounting hole A5 and the central axis of the third mounting hole A6 can be vertically arranged, and the first connecting portion 211 can be snapped into the second mounting hole A5.

[0120] like Figure 3-11 As shown in combination, the present application can also be provided with a fixing member 7, which is engaged with the connecting seat 4 by means of the third mounting hole A6; through this arrangement, when the handle 6 is rotated, the connecting seat 4 can be driven, thereby driving the rotating member 2 to rotate relative to the seat body 11, and the lock box is controlled by the second connecting part 212 to unlock or lock; the lubricant built into the gasket 3 and the connecting seat 4 can play a lubricating role, thereby improving the durability of the handle.

[0121] Exemplarily, the fixing member 7 can be a machine screw, a screw, a jackscrew or a pin; through this arrangement, the fixing member 7 can fix the handle 6 to the connecting seat 4, thereby improving the stability of the product.

[0122] Exemplarily, a mounting groove may be provided on the side of the connecting seat 4 facing the gasket 3, and the gasket 3 is installed in the mounting groove; through this arrangement, when the connecting seat 4 rotates relative to the seat body 11, the lubricant located in the connecting seat 4 can lubricate the gasket 3, and the arrangement of the gasket 3 can further reduce the friction coefficient between the connecting seat 4 and the seat body 11, and reduce the force loss during rotation.

[0123] Exemplarily, a mounting groove may be provided on one side of the seat body 11 facing the gasket 3, and the gasket 3 is installed in the mounting groove, which has the same function as the above-mentioned gasket 3 and is not described again here.

[0124] Exemplarily, a gasket 3 is provided between the seat body 11 and the connecting seat 4, and its function is the same as that of the above-mentioned gasket 3, which will not be described in detail here.

[0125] In some embodiments, a lock includes the handle and lock box (prior art) described above, and one end of the main body is connected to the lock box.

[0126] Specifically, the second connection part 212 of the main body 21 is detachably connected to the lock box. By rotating the handle 6, the connection seat 4 and the rotating member 2 can be driven, and the second connection part 212 of the rotating member 2 can synchronously rotate the internal structure of the lock box to unlock or lock the lock box.

[0127] This application operates in one way: Figure 1-11 As shown in combination, the fixed seat 1 can be fixedly connected to the window sash (in the prior art, the window sash is the frame of the door and window and its accessories, and a lock box can be installed in the window sash). The fixed seat 1 includes a seat body 11 and a plurality of holding components 12. The seat body 11 is provided with a first through hole A1 and a plurality of limiting channels B. The plurality of limiting channels B are arranged at intervals along the circumference of the first through hole A1. One end of the limiting channel B passes through the hole wall of the first through hole A1, that is, the limiting channel B is connected to the first through hole A1, and the main body 21 is rotatably inserted into the first through hole A1.

[0128] It can be understood that when the main body 21 rotates relative to the seat body 11, the limiting part 22 located on the side of the main body 21 can be driven to rotate. Since the elastic member 122 is elastically matched between the holding member 121 and the inner wall of the corresponding limiting channel B, the first recessed structure 221 or the second recessed structure 222 of the limiting part 22 can be in elastic contact with the holding member 121. In other words, the main body 21 and the holding member 121 can have a first rotation position or a second rotation position in the rotational cooperation; When the main body 21 is in the first rotation position, since the opening of the first recessed structure 221 is larger than the opening of the second recessed structure 222, at least one pressing member 121 can slide into the first recessed structure 221 in response to the elastic force of the elastic member 122 to limit the rotation of the rotating member 2; when the main body 21 is in the second rotation position, at least one pressing member 121 can slide into the second recessed structure 222 in response to the elastic force of the elastic member 122, so that the pressing member 121 collides with the inner wall of the second recessed structure 222 and makes a sound.

[0129] This application operates in the following way: Figure 1-11 As shown in combination, the present application may further include a locking portion 13 disposed on the hole wall of the first through hole A1 , and at least a portion of the limiting portion 22 is accommodated in the first through hole A1 and abuts against the locking portion 13 .

[0130] When the main body 21 rotates relative to the seat 11, the limiting part 22 located on the side of the main body 21 can be driven to rotate. Since the elastic member 122 is elastically matched between the holding member 121 and the inner wall of the corresponding limiting channel B, the first recessed structure 221 or the second recessed structure 222 of the limiting part 22 can be in elastic contact with the holding member 121. In other words, the main body 21 and the holding member 121 can have a first rotation position or a second rotation position in the rotational cooperation; when the main body 21 is in the first rotation position, the first recessed structure 221 or the second recessed structure 222 of the limiting part 22 can be in elastic contact with the holding member 121. In a rotational position, since the opening of the first recessed structure 221 is larger than the opening of the second recessed structure 222, at least one pressing member 121 can slide into the first recessed structure 221 in response to the elastic force of the elastic member 122 to limit the rotation of the rotating member 2; when the main body 21 is in the second rotational position, at least one pressing member 121 can slide into the second recessed structure 222 in response to the elastic force of the elastic member 122, so that the pressing member 121 collides with the inner wall of the second recessed structure 222 and makes a sound.

[0131] When installing the handle, the assembler only needs to abut the limiting portion 22 with the locking portion 13 to align the limiting portion 22 with the holding member 121. Since the holding assembly 12 is circumferentially distributed in the first through hole A1, the assembler does not need to consider the tightness of the matching between the limiting portion 22 and the holding member 121, and can achieve quick installation.

[0132] When the user uses the product of the present application, the locking portion 13 can be fixed to the base body 11. The locking portion 13 serves to limit the limiting portion 22, thereby improving the possibility of the rotating member 2 being disengaged from the first through hole A1 and reducing the failure rate.

[0133] This application operates in three ways: Figure 1-11 As shown in combination, the present application may further include a gasket 3 and a connecting seat 4, the gasket 3 is arranged between the connecting seat 4 and the seat body 11, and the connecting seat 4 is equipped with a receiving groove 41 for receiving lubricant.

[0134] The rotating connecting seat 4 can drive the rotating member 2 to rotate. When the main body 21 rotates relative to the seat body 11, the limiting portion 22 located on the peripheral side of the main body 21 can be driven to rotate. Since the elastic member 122 is elastically matched between the holding member 121 and the inner wall of the corresponding limiting channel B, the first recessed structure 221 or the second recessed structure 222 of the limiting portion 22 can be in elastic contact with the holding member 121. In other words, the main body 21 and the holding member 121 can have a first rotation position or a second rotation position in the rotational cooperation. The main body 21 is located in the first rotation position. Since the opening of the first recessed structure 221 is larger than the opening of the second recessed structure 222, at least one pressing member 121 can slide into the first recessed structure 221 in response to the elastic force of the elastic member 122 to limit the rotation of the rotating member 2; when the main body 21 is located in the second rotation position, at least one pressing member 121 can slide into the second recessed structure 222 in response to the elastic force of the elastic member 122, so that the pressing member 121 collides with the inner wall of the second recessed structure 222 and makes a sound.

[0135] This application operates in four ways: Figure 1-11 As shown in combination, the present application may also include a handle 6, the main body 21 includes a first connection part 211 and a second connection part 212 connected to each other, and a limiting part 22 is provided on the surrounding side of the connection between the first connection part 211 and the second connection part 212; the first connection part 211 is connected to the handle 6, and the second connection part 212 is used to connect the lock box; the handle also includes a gasket 3 and a connecting seat 4, the gasket 3 is arranged between the connecting seat 4 and the seat body 11, and the connecting seat 4 is equipped with a accommodating groove 41 for accommodating lubricant.

[0136] By turning the handle 6, the connecting seat 4 and the rotating member 2 can be rotated. When the main body 21 of the rotating member 2 rotates relative to the seat body 11, the limiting portion 22 located on the peripheral side of the main body 21 can be driven to rotate. Since the elastic member 122 is elastically matched between the pressing member 121 and the inner wall of the corresponding limiting channel B, the first recessed structure 221 or the second recessed structure 222 of the limiting portion 22 can be in elastic contact with the pressing member 121. In other words, the main body 21 and the pressing member 121 can have a first rotation position or a second rotation position in the rotational cooperation. position; when the main body 21 is in the first rotation position, since the opening of the first recessed structure 221 is larger than the opening of the second recessed structure 222, at least one pressing member 121 can slide into the first recessed structure 221 in response to the elastic force of the elastic member 122 to limit the rotation of the rotating member 2; when the main body 21 is in the second rotation position, at least one pressing member 121 can slide into the second recessed structure 222 in response to the elastic force of the elastic member 122, so that the pressing member 121 collides with the inner wall of the second recessed structure 222 and makes a sound.

[0137] When the handle 6 is rotated, the rotation force can pass through the handle 6-rotating member 2 (the first connecting portion 211, the limiting portion 22 and the second connecting portion 212)-lock box in sequence, so that the lock box can unlock or lock the door or window.

[0138] It should be noted that the above-mentioned operating mode is only for illustrative purposes and does not necessarily limit other possible operating modes of the present application.

[0139] The technical features of the above embodiments may be combined arbitrarily.
