As used in the present application specification and the appended claims, the singular forms "a", "an" and "the" are intended to include the plural forms, unless the context clearly indicates otherwise.

[0035] It should be further understood that the term "and / or" used in the present application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations thereof.

[0036] Please refer to Figures 1-4 The present application provides a door and window handle locking structure for clamping the handle on a profile or base 1, comprising two handles 2, a shaft component 3, an actuator 4 and a locking member 5, the two ends of the shaft component 3 are connected with the two handles 2 respectively, the shaft component 3 is provided with a first accommodating portion 6 axially, the actuator 4 is arranged in the first accommodating portion 6, the shaft component 3 is provided with at least one second accommodating portion 7 radially, the locking member 5 is arranged in the second accommodating portion 7 radially movably, the profile or base is provided with a locking portion 8 corresponding to the locking member 5, the first accommodating portion 6 and the second accommodating portion 7 are communicated, and the actuator 4 can drive the locking member 5 to extend to be clamped in the locking portion 8.

[0037] The present application only uses the shaft component 3, the knob 4 and the locking component 5 to realize the indoor locking and outdoor unlocking function, has simple structure, improves the assembly production efficiency, reduces the cost, and does not need other additional accessories, so that the handle 2 is universal, and there is no need to distinguish left and right, and the universality is strong.

[0038] The working principle is that when the handle 2 needs to be locked, the knob 4 is rotated to change the driving radius of the contact point of the knob 4 and the locking component 5 (that is, the distance between the locking component 5 and the axis of the shaft component 3 is constantly changed), so that the locking component 5 is moved into the locking part 8, at this time, the locking component 5 is between the shaft component 3 and the base 1, or the locking component 5 is between the shaft component 3 and the profile, so as to limit the rotation of the shaft component 3, and the handle 2 connected with the shaft component 3 cannot be rotated, so as to realize the locking of the handle 2 (as shown in Figure 5 The handle 2 is unlocked by only rotating the knob 4 to make the locking component 5 separate from the locking part 8 (as shown in Figure 6 ).

[0039] In order to realize that the rotation of the knob 4 can change the driving radius of the contact point of the knob 4 and the locking component 5, the distance between the rotation center line of the knob 4 and at least two points on the outer periphery of the knob 4 is different, the knob 4 rotates around the rotation center line, the distance between the rotation center line of the knob 4 and at least two points on the outer periphery of the knob 4 includes the maximum distance and the minimum distance, when the distance between the contact point of the knob 4 and the locking component 5 and the rotation center line of the knob 4 is the minimum distance, the locking component 5 separates from the locking part 8, and the handle 2 is in the unlocked state, when the distance between the contact point of the knob 4 and the locking component 5 and the rotation center line of the knob 4 is the maximum distance, the locking component 5 is located in the locking part 8, and the handle 2 is in the locked state, for example, when the knob 4 is a cuboid, the center line arranged along the length direction of the cuboid is taken as the rotation center line, at this time, the distance between the rotation center line and the four corners is the maximum distance, and the distance between the rotation center line and the centers of the four edges is the minimum distance, when the contact point of the knob 4 and the locking component 5 is the center of the four edges, the distance between the contact point of the knob 4 and the locking component 5 and the rotation center line of the knob 4 is the minimum distance, the locking component 5 separates from the locking part 8, and the handle 2 is in the unlocked state, when the contact point of the knob 4 and the locking component 5 is the four corners, the distance between the contact point of the knob 4 and the locking component 5 and the rotation center line of the knob 4 is the maximum distance, the locking component 5 is located in the locking part 8, and the handle 2 is in the locked state.

[0040] Further, the toggle member 4 adopts a cubic structure design, the toggle member 4 can also adopt a triangular prism design or a special-shaped body design, and even the toggle member 4 can also adopt a cylindrical design, which only needs to be arranged with the rotation position deviating from the center of the circle, in other words, the rotation center line of the cylinder deviates from the axis of the cylinder, it can be understood that the shape design of the toggle member 4 only needs to meet the condition that the driving radius of the contact point between the toggle member 4 and the locking member 5 can be changed during the rotation process of the toggle member 4.

[0041] If the corners of the toggle member 4 are not arranged in an arc shape, the corners of the toggle member 4 are prone to produce debris during the long-term abutment with the locking member 5 or the shaft component 3, which can further cause damage to the toggle member 4, the locking member 5 and the shaft component 3, and increase the replacement and maintenance costs. The corners of the toggle member 4 can be arranged in an arc shape, which makes the rotation of the toggle member 4 more smooth, and at the same time, improves the service life of the toggle member 4, the locking member 5 and the shaft component 3.

[0042] In the embodiment, as shown in Figure 2 , the first accommodating portion 6 on the shaft component 3 is a through hole, and the second accommodating portion 7 is an accommodating groove arranged on one side of the shaft component 3, and the length of the second accommodating portion 7 is less than the length of the shaft component 3, and / or, as shown in Figure 3 , the first accommodating portion 6 is a through hole, and the second accommodating portion 7 on the shaft component 3 is an accommodating groove penetrating the shaft component in the length direction and radially communicating with the first accommodating portion 6, in other words, the second accommodating portion 7 and the first accommodating portion 6 form an accommodating groove 9 with one side open on the shaft component 3.

[0043] Among them, only one second accommodating portion 7 and one locking member 5 can be arranged to lock the handle 2 (as shown in Figure 7 ), and the design of only one second accommodating portion 7 and one locking member 5 is simple in structure, high in assembly efficiency and low in manufacturing cost.

[0044] Further, in order to avoid that one locking member 5 cannot effectively lock the handle 2, in the embodiment, two second accommodating portions 7 are arranged, and the two second accommodating portions 7 are arranged on opposite sides of the shaft component 3 (as shown in Figure 5 and Figure 6 ), or the two second accommodating portions 7 are arranged on adjacent sides of the shaft component 3, or a plurality of second accommodating portions 7 can also be arranged on the same side of the shaft component 3 (for the case that the second accommodating portion 7 is an accommodating groove arranged on one side of the shaft component 3, and the length of the second accommodating portion 7 is less than the length of the shaft component 3), wherein the plurality of second accommodating portions 7 are correspondingly provided with locking members 5.

[0045] Please refer to Figure 8In order to facilitate the installation of the handle 2, a convex step 10 is extended from one end of the handle 2 close to the shaft component 3 along the axis direction of the shaft component 3, and the convex step 10 on the handle 2 can be directly clamped on the base 1 or the profile, which is convenient for installation and has high assembly efficiency.

[0046] Please refer to Figure 1 In order to facilitate the rotation of the rotating knob 11, the rotating knob 11 is arranged on the handle 2, and one end of the rotating knob 11 is connected with the rotating member 4.

[0047] In the embodiment, the rotating member 4 and the rotating knob 11 are detachably connected, which improves the convenience, so that the user can easily install and disassemble the rotating member 4 and the rotating knob 11. This flexibility helps the user to more conveniently maintain and repair, and also facilitates transportation and storage. In addition, the detachable connection can improve the reuse rate and recycling potential of the product.

[0048] In the embodiment, the rotating member 4 and the rotating knob 11 are detachably connected, which improves the convenience, so that the user can easily install and disassemble the rotating member 4 and the rotating knob 11. This flexibility helps the user to more conveniently maintain and repair, and also facilitates transportation and storage. In addition, the detachable connection can improve the reuse rate and recycling potential of the product.

[0049] Please refer to Figures 8-10 In order to realize the arrangement of the rotating knob 11 on the handle 2, a first mounting hole 12 for mounting the rotating knob 11 and a first accommodating hole 13 communicating with the first mounting hole 12 are arranged on the handle 2, and a first buckle 14 close to one end of the rotating member 4 is arranged on the rotating knob 11. When the rotating knob 11 is mounted in the first mounting hole 12, the first buckle 14 is assembled and limited with the bottom end surface of the first accommodating hole 13.

[0050] More specifically, the first accommodating hole 13 is used for mounting the shaft component 3, and the hole diameter of the first accommodating hole 13 is greater than the hole diameter of the first mounting hole 12. The hole diameter of the first accommodating hole 13 is set to be greater than the hole diameter of the first mounting hole 12 to form a step, so that the first buckle 14 can be assembled and limited with the bottom end surface of the first accommodating hole 13; the first buckle 14 includes a plurality of anti-dropping columns, when the first buckle 14 is clamped into the first mounting hole 12, the bottom of the anti-dropping column abuts and limits with the bottom end surface of the first accommodating hole 13, and each anti-dropping column is separately arranged, in other words, each anti-dropping column has a gap with its adjacent components, during the process of clamping the first buckle 14 into the first mounting hole 12, the gap between each anti-dropping column and its adjacent components decreases, and the anti-dropping column elastically deforms, when the first buckle 14 is clamped into the first mounting hole 12, the anti-dropping column restores to the original state, and the bottom of the anti-dropping column abuts and limits with the bottom of the first accommodating hole 13.

[0051] Please refer toFigure 1 To solve the problem of the large gap between the shaft component 3 and the handle 2 in the existing handle 2 structure, which causes the handle 2 to shake and the user experience to be poor, a threaded hole is arranged on the handle 2 perpendicular to the first accommodating hole 13. When the shaft component 3 is installed in the first accommodating hole 13, a threaded part 15 is screwed into the threaded hole and tightly abuts against the shaft component 3 to achieve stable connection of the shaft component 3 and the handle 2, thereby improving the user experience.

[0052] Please refer to Figures 5-9 To enable the user to perfectly perceive that the handle is in a locked or unlocked state, i.e., to achieve positioning of the inner knob 11, a plurality of positioning holes 16 are arranged annularly on the inner knob 11, and a positioning assembly 17 is arranged on the handle 2; or the positioning assembly 17 is arranged on the inner knob 11, and a plurality of positioning holes 16 are arranged annularly on the handle 2. When the positioning assembly 17 is clamped into the positioning hole 16, the handle is in a locked or unlocked state. For example, if the handle is in a locked state, the positioning assembly 17 is clamped in a certain positioning hole 16. When the positioning assembly 17 is clamped into an adjacent positioning hole 16, the handle is in an unlocked state. When the positioning assembly 17 is clamped into the positioning hole 16, the inner knob 11 is subjected to a large resistance in the direction of rotation, which can provide a large perception force for the user.

[0053] Please refer to Figure 1 The positioning assembly 17 can adopt a structure design of a spring 18 and a ball 19, and the spring 18 and the ball 19 abut against each other. The ball cooperates with the positioning hole 16 to achieve positioning of the position of the inner knob 11. A structure design of a spring and a roller can also be adopted.

[0054] To facilitate rotation of the inner knob 11, a power assisting part 20 (as shown in Figure 10 ) is arranged on the inner knob 11 away from the actuating part 4. The power assisting part 20 is usually designed as a protrusion. Further, in order to be aesthetically pleasing, the power assisting part 20 is usually small in size. Therefore, the user's fingers often slip off the power assisting part 20 during use. To avoid slipping, anti-slip lines are arranged on the power assisting part 20. The surface of the power assisting part 20 can also be made of an anti-slip material or embedded with an anti-slip material, such as rubber or plastic.

[0055] Usually, indoor and outdoor knobs need to be distinguished. In order to protect the property and life safety of the user, the outdoor knob needs to consider anti-theft and safety to avoid outsiders from easily unlocking. The indoor rotation does not need to consider anti-theft and safety, and therefore the indoor knob only needs to consider convenience. Therefore, the present embodiment further provides an outer knob 21 (as shown in Figure 11 ), which is arranged on the handle 2 and connected with one end of the actuating part 4.

[0056] In this embodiment, the structure design of the outer knob 21 near one end of the actuator 4 is similar to that of the inner knob 11, and both are fixed with the handle 2 by assembling limiting of the buckle and the bottom end face of the accommodating hole. Specifically, the outer knob 21 near one end of the handle 2 is provided with a first buckle 14, and when the outer knob 21 is installed in the first mounting hole 12, the first buckle 14 is assembled and limited with the bottom end face of the first accommodating hole 13. This design makes the indoor and outdoor use the same handle 2, further improves the universality of the handle 2, reduces the production and design cost, reduces the flow of distinguishing indoor and outdoor handles 2 in the assembly process, and improves the assembly efficiency.

[0057] Further, in order to prevent emergencies, for example, the indoor personnel suddenly gets sick, and the indoor handle 2 is locked, the outdoor personnel cannot unlock the handle 2 to provide first aid to the indoor user in time, and the like, therefore, the outer knob 21 of this embodiment is provided with an emergency slot 22 (as shown in Figure 11 ) at the end away from the actuator 4, which is used to unlock the handle 2 in an emergency.

[0058] Further, the locking device can also be provided on the outdoor knob 21, so that the outdoor unlocking needs to use a special tool to unlock, further increasing the safety of the handle 2.

[0059] Further, the outer knob 21 can also be provided with a corresponding positioning component 17 and positioning hole 16 to realize the perception of locking and unlocking of the handle 2.

[0060] It should be noted that the indoor and outdoor can use the outer knob 21, that is, both ends of the actuator 4 can be connected with two outer knobs 21.

[0061] Please refer to Figure 12 In this embodiment, a gasket 23 is also provided, which is used to reduce the friction between the handle 2 and the base 1 or other structures. The gasket 23 is provided with a polygonal stepped hole 24 for penetrating the shaft component 3 and being installed on the handle 2. The inner wall of the polygonal stepped hole 24 is provided with a notch 25 for allowing the locking member 5 to slide and preventing the locking member 5 from falling off.

[0062] The inner wall of the polygonal stepped hole 24 is provided with a plurality of positioning bosses 26, and the corresponding positioning grooves 27 (as shown in Figure 8 ) are provided on the boss step 10 of the handle 2. The gasket 23 is fixedly installed on the handle 2 by cooperation of the positioning bosses 26 and the positioning grooves 27.

[0063] Further, the end of the handle 2 of this embodiment away from the shaft component 3 is provided with a concave step 28 (as shown in Figure 9The recessed step 28 is mainly arranged for mounting the knob, so that the surface of the end of the knob away from the shaft part 3 is flush with the surface of the end of the handle 2 away from the shaft part 3, so that the whole handle 2 is more beautiful, and the recessed step 28 can also limit the knob, so that the knob can only rotate within the range of the recessed step 28, so that the knob cannot rotate off the shaft center, reducing the damage of the buckle caused by the rotation of the knob off the shaft center, and further reducing the maintenance and replacement cost.

[0064] The embodiment also provides a door and window structure comprising the door and window handle locking structure.

[0065] The embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments. The same or similar parts of each embodiment can be referred to each other. For the device disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple, and the related parts can be referred to the method part.
