Description
Technical Field
[0001] This utility model belongs to the field of door and window technology, specifically relating to a door and window that is easy to open and close. Background Technology
[0002] Sliding doors and windows are a widely used type of door and window opening and closing mechanism, offering advantages such as smooth operation, ease of opening, durability, and reasonable price. Sliding doors and windows typically consist of a fixed frame that is fixed to the building structure and a sliding section that slides along the fixed frame. The sliding section is plate-shaped and, depending on the application, can be made of wood or metal in one piece, or can consist of glass and a frame, or a screen and a frame.
[0003] Some sliding parts have handles or recesses for easy pushing of doors and windows. Handles are convenient to operate, but they protrude from the sliding part and can easily get caught on the handle while moving, especially in households with small children, who are more likely to get caught on the handle while playing. Recesses are recessed into the sliding part and do not obstruct movement, but they are less convenient for applying force. Summary of the Invention
[0004] In order to overcome the shortcomings of the prior art, this utility model provides a door and window that is more convenient to use than the prior art and does not easily obstruct people's movement when not in use.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a door and window that is easy to open and close, comprising a fixed frame and a plate-shaped sliding part, wherein the sliding part is slidably connected to the fixed frame, characterized in that: it also includes a handle, wherein the edge of the sliding part is provided with an embedded groove, and a fixed rod perpendicular to the sliding direction of the sliding part is provided in the embedded groove, the handle includes a fixed part and a rod-shaped operating part, wherein the fixed part is sleeved on the fixed rod, the operating part is located on the side of the fixed part away from the fixed rod, the operating part is parallel to the fixed rod, and a notch is provided on the embedded groove, wherein the width of the notch along the axial direction of the fixed rod is greater than the width of the fixed part along the axial direction of the fixed rod, and less than or equal to 1 / 2 the width of the embedded groove along the axial direction of the fixed rod.
[0006] With the above solution, when there is a misalignment between the fixing part and the notch, the handle can only move along the axial direction of the fixing rod; when the fixing part is aligned with the notch, the handle can rotate circumferentially along the fixing rod.
[0007] When the handle is not in use, align the fixed part with the notch and rotate the handle circumferentially along the fixed rod until the fixed part is inserted into the notch. This prevents the handle from protruding from the sliding part and avoids people getting caught on the handle during movement. When the handle is in use, rotate the handle circumferentially along the fixed rod to move the fixed part away from the notch, and then move the handle axially along the fixed rod to misalign the fixed part with the notch. This restricts the rotation of the handle through the insertion groove, making it convenient for people to move the sliding part using the handle.
[0008] As a further feature of this invention, the notch is provided with a strip-shaped protrusion, which is located on the side of the notch near the opening of the embedding groove, and the cross-section of the protrusion is an arc surface smaller than a semicircle.
[0009] By adopting the above solution, the fixing part will not automatically detach from the notch.
[0010] As a further feature of this invention, the handle is U-shaped, and there are two fixing parts located at both ends of the operating part.
[0011] The above solution allows people to operate the handle more stably and makes it easier for them to operate the sliding part through the handle.
[0012] As a further feature of this utility model, the handle is provided with a limiting end, and there are at least two sliding parts. A limiting part is provided at the edge of the sliding part adjacent to the sliding part where the embedding groove is located, and the limiting part includes a limiting cavity.
[0013] With the above solution, when the present invention is in the closed state and the fixing part rotates along the fixing rod into the notch, the limiting end and the limiting cavity form a limit, which can lock the two adjacent sliding parts to prevent accidental contact.
[0014] As a further feature of this utility model, there are two limiting ends, which are respectively located at the connection between the two fixing parts and the operating part.
[0015] The above solution provides a more stable locking effect, while the gap between the two limit ends allows people to turn the handle through the operating part.
[0016] As a further feature of this invention, the limiting cavity is a through cavity.
[0017] The above solution facilitates processing and reduces the thickness of the limiting part.
[0018] As a further feature of this invention, the side wall of the limiting cavity is provided with an opening, which is disposed opposite to the operating part.
[0019] The above solution allows people to easily place their hands between the operating part and the limiting cavity.
[0020] The present invention will now be further described with reference to the accompanying drawings. Attached Figure Description

[0026] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0027] In the description of this utility model, it should be noted that, unless otherwise specified, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0028] Specific embodiments of this utility model are shown in the accompanying drawings.
[0029] A convenient door / window includes a fixed frame 1, a plate-shaped sliding part 2, and a U-shaped handle 3. The sliding part 2 is slidably connected to the fixed frame 1. An embedding groove 4 is provided at the edge of the sliding part 2, and a fixed rod 41 perpendicular to the sliding direction of the sliding part 2 is provided within the embedding groove 4. The handle 3 includes a fixed part 31 and a rod-shaped operating part 32. There are two fixed parts 31, located at both ends of the operating part 32. The fixed part 31 is fitted onto the fixed rod 41. The operating part 32 is located on the side of the fixed part 31 away from the fixed rod 41 and is parallel to the fixed rod 41. A notch 42 is provided in the embedding groove 4. The width of the notch 42 along the axial direction of the fixed rod 41 is greater than the width of the fixed part 31 along the axial direction of the fixed rod 41, but less than half the width of the embedding groove 4 along the axial direction of the fixed rod 41.
[0030] When the fixing part 31 is misaligned with the notch 42, the handle 3 can only move along the axial direction of the fixing rod 41. When the fixing part 31 is aligned with the notch 42, the handle 3 can rotate circumferentially along the fixing rod 41.
[0031] The shape of the handle 3 facilitates operation of the sliding part 2. When the handle 3 is not in use, the fixing part 31 is aligned with the notch 42, and the handle 3 is rotated circumferentially along the fixing rod 41 until the fixing part 31 is inserted into the notch 42. This prevents the handle 3 from protruding from the sliding part 2 and avoids it from getting caught on the handle 3 during movement. When the handle 3 is needed, it is rotated circumferentially along the fixing rod 41, causing the fixing part 31 to move away from the notch 42. Then, the handle 3 is moved axially along the fixing rod 41, causing the fixing part 31 to be misaligned with the notch 42. This restricts the rotation of the handle 3 through the insertion groove 4, allowing people to move the sliding part 2 using the handle 3.
[0032] The notch 42 has a strip-shaped protrusion 43, which is located on the side of the notch 42 near the opening of the insertion groove 4. The cross-section of the protrusion 43 is an arc surface smaller than a semicircle. This prevents the fixing part 31 from automatically disengaging from the notch 42.
[0033] The handle 3 is provided with a limiting end 33. In this embodiment, there are two sliding parts 2. A limiting part 5 is provided at the edge of the sliding part 2 adjacent to the sliding part 2 where the embedding groove 4 is located. The limiting part 5 includes a limiting cavity 51. In this embodiment, when the fixed part 31 is in the closed state and rotates along the fixed rod 41 into the notch 42, the limiting end 33 and the limiting cavity 51 form a limit, which can lock the two adjacent sliding parts 2 and prevent accidental contact.
[0034] There are two limiting ends 33, which are respectively located at the connection between the two fixed parts 31 and the operating part 32. This provides a more stable locking effect, while the gap between the two limiting ends 33 allows people to rotate the handle 3 through the operating part 32.
[0035] The limiting cavity 51 is a through cavity. This facilitates processing and reduces the thickness of the limiting part 5.
[0036] An opening 52 is provided on the side wall of the limiting cavity 51, and the opening 52 is disposed opposite to the operating part 32. This allows people to easily place their hands between the operating part 32 and the limiting cavity 51.
[0037] This utility model is not limited to the specific embodiments described above. Those skilled in the art can implement this utility model using other specific embodiments based on the content disclosed in this utility model. Any simple changes or modifications made to the design structure and concept of this utility model will fall within the protection scope of this utility model.
