For those skilled in the art, the specific meaning of the terms in the present application can be understood according to the specific circumstances.

[0021] The embodiment discloses a lock, which comprises a handle, the handle is simple in structure, easy to install, can greatly simplify the structure of the lock, save cost, and is convenient to install.

[0022] Referring to Figures 1-11 , the handle comprises a handle member 10, a positioning member 20, a rotating shaft 30 and a rotating assembly 40, the positioning member 20 is used for fixedly connecting to the surface of the door and window profile; one end of the rotating shaft 30 is used for connecting transmission hardware in the door and window profile, the other end of the rotating shaft 30 is rotatably penetrated through a through hole on the positioning member 20 and then fixedly connected to the handle member 10, the handle member 10 is used for applying a rotating force to the rotating shaft 30; the rotating assembly 40 is at least partially accommodated in the handle member 10 and clamped between the handle member 10 and the positioning member 20; the rotating assembly is provided with a rotating hole 401 and an elastic ball member capable of being extended and retracted, the positioning member 20 is provided with a plurality of clamping grooves 21, the rotating shaft 30 is slidably penetrated in the rotating hole 401 and used for driving the rotating assembly 40 to rotate synchronously, and the elastic ball member is used for extending into the corresponding clamping groove 21 on the positioning member 20 when the rotating assembly 40 rotates to a preset position.

[0023] The rotating shaft 30 is a square shaft, the through hole is a circular hole capable of penetrating the direction shaft, and the rotating hole 401 is a square hole matched with the shape of the direction shaft.

[0024] The handle of the present scheme separates the handle member 10 and the positioning member 20 by designing the rotating assembly 40 as an independent structural member, and only needs to be matched with the positioning member 20 provided with the clamping groove 21, so that different types of handle members 10 can be adapted, and the universality of the rotating assembly 40 is improved. The rotating assembly 40 is at least partially accommodated in the handle member 10, which indicates the installation position of the rotating assembly 40, and only needs to be sleeved outside the handle member 10, and compared with being arranged in the positioning member 20, the installation and positioning mode is simpler.

[0025] Compared with the prior art, the rotating assembly 40 of the present scheme does not need to be fixedly installed with the positioning member 20 or the handle member 10, simplifying the operation process and improving the installation efficiency. The handle of the present scheme has strong versatility and is easy to install, which can save costs, improve the accuracy and reliability of the handle positioning, and expand the application range of the handle.

[0026] It should be noted that in the present scheme, the eight clamping grooves 21 are uniformly distributed along the circumference of the through hole, the elastic ball member includes four, and each time the rotating angle is 45 degrees, the corresponding preset position is entered, the operator's holding feeling changes, and the elastic ball also accompanies the sound of resisting the clamping groove 21, which can accurately position and improve the operation experience of the operator.

[0027] Further referring to Figures 3-4 and Figure 7 , the rotating assembly 40 includes a rotating box body 41 and a rotating cover body 42, the rotating box body 41 is provided with a containing hole 411 for positioning one end of the elastic ball member; the rotating cover body 42 is provided with a positioning hole 421 for abutting the other end of the elastic ball member, the rotating cover body 42 is covered on the rotating box body 41, and the other end of the elastic ball member can be extended out of the positioning hole 421.

[0028] The elastic ball member inside the rotating assembly 40 is effectively accommodated and guided. The containing hole 411 in the rotating box body 41 provides stable positioning for one end of the elastic ball member, and the positioning hole 421 on the rotating cover body 42 accurately guides the other end of the elastic ball member to perform extension and retraction movement. This structure design ensures that the movement trajectory of the elastic ball member inside the rotating assembly 40 is accurate and reliable, avoiding the problem of inaccurate positioning caused by loose or misaligned parts. When the handle is rotated to the preset position, the elastic ball member can reliably extend out of the positioning hole 421 and accurately clamp into the clamping groove 21 on the positioning member 20, providing clear positioning feeling and stable locking effect. At the same time, when the handle is rotated, the elastic ball member can smoothly retract into the positioning hole 421, realizing smooth unlocking and rotation, significantly improving the smoothness, positioning accuracy and overall reliability of the handle operation.

[0029] It can be understood that the elastic ball member includes a spring 43 and a steel ball 44, the containing hole 411 is a strip-shaped hole matched with the shape and size of the spring 43, and the spring 43 always applies a force to the steel ball 44 to resist the positioning hole 421. The diameter of the positioning hole 421 is smaller than the diameter of the steel ball 44, so that the steel ball 44 can protrude a part outside the positioning hole 421, and if it encounters the blocking part of the positioning member 20, it will retract into the positioning hole 421, and if it encounters the clamping groove 21 of the positioning hole, it will enter the clamping groove 21.

[0030] In one embodiment, the rotating assembly further includes a rotating connector 45 for connecting the rotating box body 41 and the rotating cover body 42.

[0031] In existing technologies, since the transmission box is fixed to the positioning component 20 or the handle component 10, it also needs to bear the traction force for positioning or the driving force for rotation. Therefore, the structure of the transmission box needs to be made of metal materials such as stainless steel to ensure its functional stability. In this solution, the transmission box only needs to rotate synchronously with the rotating shaft 30. There is no resistance within the handle component 10, and the requirements for strength and hardness are not high. Therefore, it can be made directly using plastic parts, which greatly saves costs.

[0032] The rotating housing 41 and rotating cover 42 are designed as plastic structural components. Plastic materials have good plasticity, allowing for the efficient and mass production of complex-shaped parts through processes such as injection molding, thus significantly reducing manufacturing costs and production cycles. At the same time, plastic structural components are generally lighter than metal components, helping to reduce the overall weight of the handle. In terms of material selection, engineering plastics with good wear resistance, self-lubricating properties, or specific strength grades can be selected according to actual needs to ensure the performance stability and durability of the rotating assembly 40 during long-term use.

[0033] See Figure 5 The handle 10 has a mounting groove 11, the rotating component 40 is located in the mounting groove 11, one end of the rotating component 40 abuts against the bottom of the mounting groove 11, and the other end of the rotating component 40 abuts against the positioning component 20.

[0034] By placing the rotating component 40 within the mounting groove 11 inside the handle 10, with one end abutting the bottom of the groove 11 and the other end abutting the positioning member 20, a protected and stable working environment is created inside the handle 10 for the rotating component 40. This effectively prevents inaccurate positioning or functional failure caused by shaking or displacement of the rotating component 40 during operation. Simultaneously, the built-in design of the rotating component 40 significantly improves the overall compactness and integration of the handle, resulting in a simpler and more aesthetically pleasing appearance, thereby increasing the handle's service life and operational reliability.

[0035] In one embodiment, the positioning member 20 is provided with a first through hole 22 and a fastening hole 23, and a locking groove 21 is provided on the positioning member 20. The first through hole 22 is used to pass through the rotating shaft 30, and the fastening hole 23 is used to connect to the surface of the door and window profile through a fastener.

[0036] The first through hole 22 provides precise guidance and support for the rotating shaft 30, ensuring smooth rotation and transmission efficiency. The fastening hole 23 provides a reliable mechanical interface for the stable connection between the positioning component 20 and the door and window profile. The locking groove 21 works in conjunction with the elastic ball bearings of the rotating assembly 40, allowing the handle to be accurately locked when rotated to the preset functional position, providing users with clear positioning feedback and a convenient operating experience, significantly improving the practicality and reliability of the handle.

[0037] In one embodiment, the handle also includes a decorative housing 50, which covers the positioning member 20 and enhances its appearance. The decorative housing 50 can be made of various materials, such as metals (e.g., aluminum alloy, stainless steel), plastics (e.g., ABS, PC), or composite materials, and its selection can be determined based on the overall design style of the handle, the usage environment, and the required protective performance. Its function is to cover and conceal the exposed portion of the positioning member 20 to improve the overall visual effect of the handle.

[0038] In one embodiment, the handle further includes a shaft connector 60. The handle 10 has a shaft positioning hole 71 and a shaft mounting hole 72. The other end of the rotating shaft 30 is inserted into the shaft positioning hole 71, and the shaft connector 60, after being inserted into the shaft mounting hole 72, abuts against and positions the rotating shaft 30. By providing dedicated shaft positioning holes 71 and 72 within the handle 10, and utilizing the shaft connector 60, the rotating shaft 30 can be precisely and securely fixed within the handle 10. This arrangement ensures the stability and reliability of the connection, effectively preventing axial movement or unnecessary play in the rotating shaft 30 during operation. After insertion, the shaft connector 60 firmly abuts against and positions the rotating shaft 30, thereby enhancing the rigidity and durability of the handle 10 and rotating shaft 30 assembly.

[0039] See Figure 6 The handle also includes a shaft connecting seat 70, which is located in the mounting groove 11. The shaft positioning hole 71 and the shaft mounting hole 72 are both located on the shaft connecting seat 70, and the end of the shaft connecting seat 70 abuts against one end of the rotating assembly 40.

[0040] The shaft connector 70 is an independent structural component whose main function is to provide a dedicated, high-precision support structure for the positioning and installation of the rotating shaft 30. The shaft connector 70 can be made of materials with high strength and wear resistance, such as metals (e.g., zinc alloys, aluminum alloys) or high-performance engineering plastics, to ensure it can withstand the torsional and axial loads of the rotating shaft 30 during long-term use and reduce wear. Its shape is typically matched to the mounting groove 11 within the handle component 10 for easy integration. Generally, the shaft connector 70 and the handle component 10 are integrally molded or welded together.

[0041] In another embodiment, the shaft connector 70 can be detachably inserted into the handle 10. By introducing an independent shaft connector 70, and setting both the shaft positioning hole 71 and the shaft mounting hole 72 of the rotating shaft 30 on the shaft connector 70, the support and positioning functions of the rotating shaft 30 are effectively separated from the handle 10. This design allows the shaft connector 70 to be made of more wear-resistant and higher-strength materials, thereby significantly improving the durability and precision of the rotating shaft 30 connection and avoiding wear or deformation of the handle 10 body due to long-term stress. The structure in which the shaft connector 70 is inserted into the mounting groove 11 not only simplifies the manufacturing process of the handle 10 but also makes the installation and replacement of the shaft connector 70 more convenient. In addition, the end of the shaft connecting seat 70 abuts against one end of the rotating component 40, which can accurately limit the axial position of each component, ensure that the fit clearance between the rotating shaft 30, the rotating component 40 and the handle 10 is reasonable, effectively prevent the axial movement of the rotating shaft 30, thereby ensuring the smoothness and stability of the handle during rotation operation, and improving the overall service life and reliability.

[0042] See Figures 1-3 The outer edge dimension of the positioning element 20 is equal to or slightly larger than the groove size of the mounting groove 11 to form a baseless handle. The outer edge dimension of the positioning element 20 is designed to be equal to or slightly larger than the groove size of the mounting groove 11 of the handle element 10. The handle presents a simple and modern "baseless" effect, greatly enhancing the overall aesthetics of the product and making the handle more harmonious and unified with the overall style of the doors and windows, providing users with a more refined and comfortable user experience.

[0043] In one embodiment, the side wall of the rotating assembly 40 is provided with a clearance groove 402 for fastener installation and removal operations. The clearance groove 402 provides the necessary space for fastener installation and removal operations. When the rotating assembly 40 abuts against the positioning member 20, the presence of the clearance groove 402 allows the tools for installing or removing the fastener to smoothly contact the fastener and perform effective operations.

[0044] See Figures 10-11 The outer edge dimension of the positioning element 20 is much larger than the opening dimension of the mounting groove 11, and it is externally mounted on the handle element 10 to form a based handle. By designing the outer edge dimension of the positioning element 20 to be larger than the opening dimension of the mounting groove 11 of the handle element 10, and making it externally mounted on the handle element 10, this application can form a based handle. This design makes the positioning element 20 a visible base for the handle, directly connected to the surface of the door and window profile, thus providing a more stable installation foundation. Compared with baseless handles, based handles have a more traditional aesthetic and structural sense. At the same time, due to the larger external dimension of the positioning element 20, its contact area with the door and window profile is increased, which can effectively disperse the force and further improve the overall installation strength and service life of the handle.

[0045] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
