Description

Technical Field

[0001] This utility model relates to the field of door and window accessories technology, specifically to a door and window handle with a free-spinning stroke. Background Technology

[0002] Doors and windows are fundamental building elements, serving as carriers of lighting, ventilation, security, views, and architectural aesthetics. Existing door and window locks achieve their locking purpose by hooking a latch to a lock seat on the frame. Most use hardware configurations such as lever actuators, push-pull lock seats, or crescent lock hooks to open and close doors and windows. However, the lock cylinders of these existing door and window locks mostly lack a free-spinning structure and a clearance, allowing them to be opened directly by turning the lever. This makes them easy for children to open, often becoming a home safety hazard that endangers children's safety. At the same time, the frequent small-angle rotation of the gears and transmission structure inside the lever without a free-spinning section increases the wear on the gear teeth. Utility Model Content

[0003] To address the technical deficiencies in the background technology, this utility model proposes a door and window handle with a free-spinning stroke, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0004] A door and window handle with a free-spinning stroke includes a lock box body and a handle body inserted into the lock box body. The lock box body includes a housing, a cover plate fastened to the housing, and a lock cylinder assembly disposed within the housing.

[0005] The lock cylinder assembly includes a drive shaft connected to the handle body and a drive slider connected to the drive shaft. The housing has a rotating chamber corresponding to the position of the drive shaft and a sliding chamber corresponding to the position of the drive slider. One end of the drive shaft connected to the handle body has a positioning structure, and the other end has a cylindrical part connected to the drive slider.

[0006] The outer surface of the cylindrical part is provided with a first toothed segment and an arc-shaped segment. The position where the transmission slider connects to the cylindrical part is provided with a toothed groove. The middle part of the toothed groove is provided with a second toothed segment that matches the first toothed segment. The two ends of the toothed groove are provided with arc-shaped grooves that match the shape of the outer surface of the cylindrical part.

[0007] As an improvement to the above solution, the housing includes an outer shell and an inner shell, and the outer shell and the inner shell are fastened together by screws to form a sliding chamber for accommodating the transmission slider;

[0008] The cover plate and the other end face of the outer shell are fastened together by screws to form a rotating chamber that accommodates the drive shaft.

[0009] As an improvement to the above solution, the side of the transmission slider is provided with an L-shaped extension, and the end face of the L-shaped extension that fits with the outer shell is provided with a first guide structure. The first guide structure includes a guide groove and a guide strip extending along the sliding direction of the transmission slider.

[0010] As an improvement to the above solution, the end face where the L-shaped extension fits with the inner shell is provided with a second guide structure. The second guide structure includes a guide groove and a guide bar extending along the sliding direction of the transmission slider.

[0011] As an improvement to the above solution, the outer edge of the rotating chamber partially overlaps with the sliding chamber, the outer edge of the cylindrical portion extends into the sliding chamber, and the inner edge of the tooth groove on the transmission slider fits against the outer edge of the cylindrical portion.

[0012] As an improvement to the above solution, the cover plate is provided with a cylindrical mounting part facing the handle body, and a through hole is opened at the axial position of the mounting part. The end of the drive shaft passes through the mounting part along the through hole and is connected to the handle body.

[0013] As an improvement to the above solution, the handle body is provided with a mounting chamber that is adapted to the shape of the mounting part and the end of the drive shaft, and the positioning structure is provided in the mounting chamber corresponding to the end face of the mounting part.

[0014] As an improvement to the above solution, the positioning structure includes a ring plate and a positioning ball. The end face of the ring plate facing the mounting part is provided with a protruding positioning block, and the inner surface of the ring plate is provided with a positioning groove. The mounting cavity is provided with an elastic member that abuts the positioning ball in the positioning groove.

[0015] The beneficial effects of this utility model are as follows:

[0016] The handle body and the transmission slider are connected and driven by the transmission shaft. The transmission shaft has an arc-shaped section in the circumference to allow the handle body to rotate freely. The free-rotation structure of the handle changes the handle's stroke from 180° to an actual effective stroke of 90°. This reduces the hook-and-loop distance between the handle and another window after the window is opened, thereby increasing the visible light range of the doors and windows. It also forms a physical barrier to prevent children and pets from accidentally opening the door and window handles. In addition, during free rotation, the first and second tooth segments are in a disengaged state to avoid accidental contact that could cause frequent small-angle rotation of the handle and wear on the tooth surface.

[0017] The other end of the drive shaft is provided with a positioning structure. The handle body provides a low-resistance pre-rotation range during the idling phase. The feel of the idling phase is different from that of the engagement phase. Users can perceive a clear critical point before entering the effective stroke. Attached Figure Description

The end of the transmission shaft 4 connected to the transmission slider 5 is provided with an idle structure that cooperates with the transmission slider 5. Through this idle structure, the handle body 3 has an idle stroke when it starts to rotate. During the idle stroke, the transmission shaft 4 and the transmission slider 5 are in a disconnected state.

[0032] It should be noted that the housing 1 is provided with a rotating chamber 13 corresponding to the position of the transmission shaft 4, the transmission shaft 4 is disposed in the rotating chamber 13, and a sliding chamber 14 is provided corresponding to the position of the transmission slider 5. The transmission slider 5 slides back and forth along the length direction of the sliding chamber 14 under the drive of the handle body 3.

[0033] Furthermore, the drive shaft 4 is provided with a positioning structure 6 at one end connected to the handle body 3, and a cylindrical part 41 connected to the drive slider 5 at the other end; the handle body 3 provides a low-resistance pre-rotation range during the idle phase, and the feel of the idle phase is different from that of the engagement phase. The user can perceive a clear critical point before entering the effective stroke. The positioning structure 6 can enhance the user's feel when rotating the handle. When rotating to the corresponding angle, the positioning structure 6 helps the user to judge the accurate starting point of the effective stroke.

[0034] Furthermore, the outer edge of the rotating chamber 13 partially overlaps with the sliding chamber 14, the outer edge of the cylindrical portion 41 extends into the sliding chamber 14, and the inner edge of the tooth groove 51 on the transmission slider 5 fits against the outer edge of the cylindrical portion 41.

[0035] It should be noted that a first toothed segment 42 and an arc-shaped segment 43 are provided around the outer surface of the cylindrical part 41. A toothed groove 51 is provided at the position where the transmission slider 5 connects with the cylindrical part 41. A second toothed segment 52 that matches the first toothed segment 42 is provided in the middle of the toothed groove 51. Arc-shaped grooves 53 that match the shape of the outer surface of the cylindrical part 41 are provided at both ends of the toothed groove 51.

[0036] When the drive shaft 4 rotates to slide the drive slider 5, at the beginning of the handle rotation, the arc segment 43 is connected to the tooth groove 51 of the drive slider 5, and the lock cylinder assembly is in the idle stroke state. After the arc segment 43 has completed its circumferential rotation, the first tooth segment 42 engages with the second tooth segment 52 in the tooth groove 51, driving the drive slider 5 to move along the sliding chamber 14. At this time, the lock cylinder assembly is in the effective stroke state.

[0037] In the technical solution of the housing 1 of this utility model, the housing 1 includes an outer shell 12 and an inner shell 11. The outer shell 12 and the inner shell 11 are fastened together by screws to form a sliding chamber 14 for accommodating the transmission slider 5.

[0038] The cover plate 2 and the other end face of the outer shell 12 are fastened together by screws to form a rotating chamber 13 that accommodates the drive shaft 4.

[0039] Furthermore, in the above solution, the side of the transmission slider 5 is provided with an L-shaped extension 54, and the end face of the L-shaped extension 54 that fits with the outer shell 12 is provided with a first guide structure 55. The first guide structure 55 includes a guide groove 551 and a guide bar 552 extending along the sliding direction of the transmission slider 5.

[0040] In the technical solution of the first guide structure 55, the guide groove 551 and the guide bar 562 are respectively opened on the opposite end faces of the L-shaped extension 54 and the outer shell 12, which are used to guide the transmission slider 5 and ensure that the transmission slider 5 slides in the sliding chamber 14 in accordance with the guiding direction of the first guide structure 55.

[0041] Furthermore, in the above scheme, the end face of the L-shaped extension 54 that fits with the inner shell 11 is provided with a second guide structure 56. The second guide structure 56 includes a guide groove 561 and a guide bar 562 extending along the sliding direction of the transmission slider 5. The second guide structure 56 has the same function as the first guide structure 55, which is to guide the sliding direction of the transmission slider 5.

[0042] Furthermore, in the above scheme, the cover plate 2 is provided with a cylindrical mounting part 21 facing the handle body 3. A through hole 22 is opened at the axial position of the mounting part 21. The end of the drive shaft 4 passes through the mounting part 21 along the through hole 22 and is connected to the handle body 3. During installation, after the drive shaft 4 passes through the rotating chamber 13, the cover plate 2 is fixed to the outer shell 12 by screws, and the drive shaft 4 is fixed at the same time.

[0043] Furthermore, in the above scheme, the handle body 3 is provided with an installation chamber 31 that is adapted to the shape of the mounting part 21 and the end of the transmission shaft 4, and the positioning structure 6 is provided in the installation chamber 31 corresponding to the end face position of the mounting part 21.
