Description

Technical Field

[0001] The utility model relates to the technical field of door and window installation, in particular to an easily detachable rotating shaft assembly and a door and window thereof. Background Art

[0002] Doors are usually installed on door frames with hinges, but both installation and removal require the removal of hinge parts such as bolts, which is very troublesome. Now there is a hinge kit that is convenient for door installation. The door can be easily installed on the door frame through a retractable hinge and a preset hole position. For example, the hinge is vertically slidably set in a sleeve and a spring is installed at one end of the hinge. The end of the spring and the top of the hinge are in conflict. An adjustment rod connected to the hinge is arranged in a horizontal position. By pushing the adjustment rod, the hinge is driven to overcome the spring elastic force and move the hinge. After letting go, it is reset under the action of the spring, thereby realizing the telescopic function of the hinge. The sleeve is installed on both sides of the door leaf, and the mounting plate with preset holes is installed on the door frame. By pushing the adjustment rod, the hinge is retracted into the sleeve. After aligning the hinge with the hole position, the adjustment rod is released, and the hinge is extended into the hole position under the action of the spring to realize the installation of the door leaf; by pushing the adjustment rod, the hinge can be extended out of the hole position to realize the rapid disassembly of the door leaf.

[0003] However, since the sleeve is arranged between the door leaf and the door frame, the adjusting rod cannot extend too far outside the sleeve for people to push. When people push the adjusting rod, they will apply an additional large lateral force to the adjusting rod, which increases the friction between the rotating shaft and the sleeve. The extension and retraction of the rotating shaft in the axial direction is not smooth and is prone to jamming, thereby reducing the efficiency of installation. Utility Model Content

[0004] The utility model aims to provide an easily disassembled rotating shaft assembly and a door and window thereof, so as to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0005] The technical solution adopted to solve the above-mentioned technical problems is: an easily detachable shaft assembly, comprising: a movable shaft sleeve, a first base and a first shaft telescopically arranged on the movable shaft sleeve, an elastic member for limiting the telescopic extension of the first shaft is arranged between the movable shaft sleeve and the first shaft, the first base is provided with a first limiting hole adapted to the first shaft, and a handle is provided at the end of the first shaft away from the first base.

[0006] This technical solution has at least the following beneficial effects: the handle portion is arranged at the end of the first rotating shaft, and people can more easily apply a force to the handle portion that is closer to the center line direction of the first rotating shaft, thereby reducing the lateral component of the applied force, thereby reducing the friction between the first rotating shaft and the movable sleeve, so that the first rotating shaft can be pulled more easily and smoothly, reducing jamming and improving the installation efficiency of the first rotating shaft; in addition, reducing the friction between the first rotating shaft and the movable sleeve can reduce the amount of wear on the outer periphery of the first rotating shaft, and it is not easy for the first rotating shaft to become loose or make abnormal noises when rotating due to severe wear due to long-term use.

[0007] As a further improvement of the above technical solution, the handle is L-shaped and has a clearance hole in the middle. People's fingers can be inserted into the clearance hole to apply force along the axis direction of the first rotating shaft to the handle, so as to pull the first rotating shaft.

[0008] A door and window comprises the above-mentioned easily detachable shaft assembly, and also comprises a fixed frame and a door and window leaf, wherein the movable shaft sleeve is mounted on the door and window leaf, and the first base is mounted on the fixed frame. The easily detachable shaft assembly is used to connect the fixed frame and the door and window leaf, and the first shaft can be extended into or extended out of the first base by acting on the handle, so that the movable shaft sleeve and the first base are in a locked or separable state, which can facilitate the installation and removal of the door and window leaf and improve the installation efficiency of the door and window.

[0009] As a further improvement of the above technical solution, the door and window sash is provided with a first slide groove for the movable sleeve to slide, and the movable sleeve is provided with a locking member, and the locking member fixes the movable sleeve by contacting the inner wall of the first slide groove. The movable sleeve slides in the first slide groove, and the position of the movable sleeve can be adjusted to adjust the length of the first rotating shaft extending relative to the door and window sash, so as to adapt to the environment where the relative heights of the upper and lower inner sides of the fixed frame are different; in addition, sliding the movable sleeve out of or into the first slide groove can also facilitate the removal and installation of the movable sleeve, and facilitate maintenance and replacement of parts.

[0010] As a further improvement of the above technical solution, the handle is slidably disposed in the first slide groove at one end away from the first rotating shaft; or the handle is slidably connected to the movable sleeve. The handle is further limited to avoid the handle rotating around the axis of the first rotating shaft and affecting the installation or opening and closing of the door and window sashes, so that the handle can be more stably stressed and convenient to use.

[0011] As a further improvement of the above technical solution, the fixed frame is provided with a second slide groove for the first base to slide, and the first base is provided with a fixing member, and the fixing member fixes the first base by pressing against the inner wall of the second slide groove. The first base slides in the second slide groove, and the position of the first base in the fixed frame can be adjusted to adjust the location of the first rotating shaft, thereby adjusting the rotation position of the door and window sash to meet the requirements of different rotation positions.

[0012] As a further improvement of the above technical solution, a groove is connected to one side wall of the second slide, and a slider that can slide in the groove is provided on one side of the first base, and the first base can embed the slider into the groove from the middle position of the second slide. Only the groove and the slider are provided on one side, so that the slider can be easily embedded in the groove from any opening position of the second slide, so that the first base falls into the second slide, which is convenient for the installation of the first base and improves the installation efficiency; at the same time, it can also make it unnecessary to set the positions of the fixed frame at both ends of the second slide to move out of the first base opening, so as to ensure the continuity between the edges of the fixed frame. The fixing member is a threaded rod, and the threaded rod is threadedly connected to the first base, and the end of the threaded rod close to the slider is inclined toward the side away from the fixed frame, so that the end of the threaded rod close to the slider is outside the second slide, and the end of the threaded rod away from the slider fixes the first base by pressing against the inner wall of the second slide. The threaded rod is arranged at an angle, and one end is outside the second slide groove, which makes it easy to use tools to rotate the threaded rod; in addition, the end of the threaded rod faces outward, which can also be convenient for the installer standing outside the fixed frame to operate, especially in the installation of small doors and windows. If the threaded rod is in a vertical state, the installer needs to get close to the fixed frame to check whether the tool is aligned with the threaded rod, etc., which is more troublesome. The end of the inclined threaded rod faces outward, which is very convenient for the installer to operate the threaded rod, thereby facilitating the fixing of the position of the first base, thereby improving the convenience and efficiency of installation.

[0013] As a further improvement of the above technical solution, positioning plates are provided on both sides of the first base, and the two positioning plates are pressed against the surface of the fixing frame. By positioning and installing the positioning plates and the fixing frame in contact with each other, the first base can be less skewed and offset, and the accuracy of the installation of the first base can be guaranteed.

[0014] As a further improvement of the above technical solution, the first base is provided with a shaft cylinder for the first rotating shaft to penetrate, a first limiting hole is formed inside the shaft cylinder, and the fixing member is arranged at the lower side of the shaft cylinder. The acting force between the fixing member and the inner wall of the second slide groove is closer to the installation position of the first rotating shaft, so that the torque formed by the combined force of the forces applied by the fixing frame and the first rotating shaft to the first base is smaller, thereby ensuring the stability of the first base during the rotation of the first rotating shaft, thereby ensuring the stability of the rotation of the door and window sash.

[0015] As a further improvement of the above technical solution, it also includes a fixed sleeve, a second rotating shaft arranged on the fixed sleeve, and a second base, wherein the fixed sleeve is installed on the side of the door and window sash away from the movable sleeve, the second base is installed on the side of the fixed frame away from the first base, and the second base is provided with a second limiting hole adapted to the second rotating shaft. The door and window sash is installed by combining the fixed sleeve and the movable sleeve, which can reduce the trouble of operating the handle on both sides and improve the convenience of installation.

[0029] Reference Figure 1 and Figure 2 An easily detachable shaft assembly includes a movable sleeve 10, a first shaft 11, an elastic member 12 and a first base 13. The movable sleeve 10 is in the shape of a hinge plate, and the first shaft 11 is movably inserted into the movable sleeve 10. The elastic member 12 is arranged between the movable sleeve 10 and the first shaft 11 to provide elastic force for the reset action of the first shaft 11. The first base 13 is provided with a first limiting hole 14, and the first limiting hole 14 is adapted to fit with the end of the first shaft 11. The first limiting hole 14 can be directly drilled on the first base 13; or a shaft cylinder 44 protruding outward can be provided on the first base 13, and the inner wall of the shaft cylinder 44 is used as the first limiting hole 14. A handle portion 15 is provided at one end of the first shaft 11 away from the first base 13. The handle portion 15 can be a part of the first shaft 11 extending out of the movable sleeve 10, or a component attached to the end of the first shaft 11.

[0030] By pulling the handle 15 at the end of the first rotating shaft 11, the first rotating shaft 11 can be subjected to an axial force parallel or nearly parallel to the axial direction of the first rotating shaft 11, thereby reducing the lateral force perpendicular to the axial direction of the first rotating shaft 11 on the first rotating shaft 11, thereby reducing the friction between the outer periphery of the first rotating shaft 11 and the inner wall of the movable sleeve 10, making it easier to pull the first rotating shaft 11 and improving the efficiency of installation; in addition, reducing the friction between the outer periphery of the first rotating shaft 11 and the inner wall of the movable sleeve 10 can also reduce the wear of the outer periphery of the first rotating shaft 11, so that it is not easy to generate a movable gap between the outer periphery of the first rotating shaft 11 and the inner wall of the movable sleeve 10 due to wear, thereby ensuring the stability of the rotation of the first rotating shaft 11 and improving the reliability of the easily disassembled shaft assembly.

[0031] In order to improve the telescopic stability of the first rotating shaft 11, the elastic member 12 is a coil spring. The outer periphery of the first rotating shaft 11 is provided with a positioning step for the coil spring to press against, and the through hole of the movable sleeve 10 for the first rotating shaft 11 to pass through is also provided with a positioning step for the coil spring to press against. The coil spring is sleeved on the outer periphery of the first rotating shaft 11 and its two ends are respectively pressed against the positioning steps of the first rotating shaft 11 and the movable sleeve 10. When the first rotating shaft 11 is pulled, the coil spring can be squeezed so that the coil spring stores potential energy for the first rotating shaft 11 to reset. The elastic member 12 is arranged in the middle of the first rotating shaft 11 and inside the movable sleeve 10, and does not affect the arrangement of the handle 15. The spatial distribution of the overall structure is reasonable, and the appearance is more beautiful and simple.

[0032] In other embodiments, the elastic member 12 may also be an elastic retractable rope, a strip groove for accommodating the elastic retractable rope is provided in the through hole of the movable sleeve 10 through which the first rotating shaft 11 passes, and the two ends of the elastic retractable rope are respectively fixed to the inside of the through hole of the movable sleeve 10 and the outer periphery of the first rotating shaft 10, and when the first rotating shaft 11 is pulled, the elastic retractable rope can be stretched, so that the elastic retractable rope stores energy for resetting the first rotating shaft 11, so as to achieve the limited extension and retraction of the first rotating shaft 11 relative to the movable sleeve 10. In other embodiments, the elastic member 12 may also be an arc-shaped elastic sheet, a accommodating groove for accommodating the arc-shaped elastic sheet is provided in the through hole of the movable sleeve 10 through which the first rotating shaft 11 passes, and the two ends of the arc-shaped elastic sheet are respectively fixed to the inner wall of the movable sleeve 10 and the outer periphery of the first rotating shaft 11, and when the first rotating shaft 11 is pulled, the arc-shaped elastic sheet can be squeezed, so that the arc-shaped elastic sheet stores energy for resetting the first rotating shaft 11, so as to achieve the limited extension and retraction of the first rotating shaft 11 relative to the movable sleeve 10.

[0033] Reference Figure 3The present embodiment also discloses a door and window, comprising the above-mentioned easily detachable shaft assembly, and also comprising a fixed frame 30 and a door and window sash 20, wherein the fixed frame 30 is fixedly mounted on a wall structure, the movable shaft sleeve 10 is mounted on the side of the door and window sash 20 that needs to rotate, and the first base 13 is mounted on one side of the fixed frame 30. By pulling the handle 15, the end of the first shaft 11 is extended into the first limiting hole 14 to connect the movable shaft sleeve 10 and the first base 13, and the first shaft 11 is limited and rotated in the first limiting hole 14, so that the door and window sash 20 can rotate relative to the fixed frame 30 around the axis of the first shaft 11, thereby realizing the rotation and opening and closing of the door and window; by pulling the handle 15, the first shaft 11 is extended out of the first limiting hole 14, and the movable shaft sleeve 10 and the first base 13 are in a state of being separable in the horizontal direction, so that the door and window sash 20 can be easily removed from the fixed frame 30, thereby realizing the extremely fast disassembly and assembly of the door and window sash 20.

[0034] Reference Figure 3-5 , a first slide groove 21 is provided on the side of the door and window sash 20 that needs to rotate, and a movable sleeve 10 is slidably arranged in the first slide groove 21 on the side close to the door and window sash 20, and the part of the movable sleeve 10 that is slidably arranged in the first slide groove 21 is T-shaped, and the first slide groove 21 is a T-shaped groove. The movable sleeve 10 is provided with a locking member 22, and the locking member 22 fixes the movable sleeve 10 by contacting the inner wall of the first slide groove 21. Specifically, the locking member 22 can be a bolt, and the bolt is threadedly connected with the movable sleeve 10. The bolt is screwed into and passed through the movable sleeve 10, and pressed against the inner wall of the first slide groove 21, thereby increasing the friction between the movable sleeve 10 and the inner wall of the first slide groove 21, so that the movable sleeve 10 can be fixed at the corresponding position of the first slide groove 21, which can facilitate the adjustment of the position of the movable sleeve 10, and can also facilitate the maintenance and replacement of the movable sleeve 10, the first rotating shaft 11, the elastic member 12 and other structures.

[0035] In other embodiments, the portion of the movable sleeve 10 that is slidably arranged in the first slide groove 21 may also be a dovetail type, and the first slide groove 21 is a dovetail groove; the locking piece 22 may also be a bolt and nut assembly, and a through hole for the bolt to pass through is opened in the movable sleeve 10, and a plurality of nuts are embedded side by side at the bottom of the first slide groove 21. The bolts are passed through the through holes of the movable sleeve 10 and screwed into the nuts, so that the position of the movable sleeve 10 can be fixed and adjusted at a fixed point.

[0036] Specifically, the handle portion 15 is an L-shaped structure, and a clearance hole 16 is opened in the middle, so that people can insert their fingers into the clearance hole 16 to apply force along the axis direction of the first rotating shaft 11 to the handle portion 15, so as to pull the first rotating shaft 11. One end of the handle portion 15 is fixedly sleeved on one end of the movable sleeve 10 extending from the first rotating shaft 11 by interference fit, and the other end is slidably set in the first slide groove 21, so that the handle portion 15 is slidably connected with the door and window sash 20, ensuring the stability of the handle portion 15 during the pulling process. In addition, one side of the handle portion 15 and the movable sleeve 10 can be restricted by the inner wall structure of the first slide groove 21, and the structural design is ingenious and the spatial layout is reasonable.

[0037] In other embodiments, the handle portion 15 can be slidably connected to the movable sleeve 10 to limit the rotation of the handle portion 15 around the axis of the first rotating shaft 11. For example, a guide rod is provided on one side of the handle portion 15, and the guide rod is slidably provided in the movable sleeve 10, so as to limit the rotation of the handle portion 15 around the axis of the first rotating shaft 11, thereby making the pulling process of the handle portion 15 more stable.

[0038] In order to facilitate the installation of the first base 13, the fixing frame 30 is provided with a second slide groove 31, the bottom of the first base 13 is slidably arranged in the second slide groove 31, and the first base 13 is provided with a fixing member 32, which fixes the first base 13 by pressing against the inner wall of the second slide groove 31. The fixing member 32 is arranged at the lower side of the shaft cylinder 44, so that the position where the fixing member 32 interacts with the side wall of the second slide groove 31 is closer to the installation position of the first rotating shaft 11, thereby making the torque formed by the combined force of the first rotating shaft 11 and the fixing frame 30 on the first base 13 smaller, and the fixing of the first base 13 is more stable, ensuring the stable rotation of the first rotating shaft 11 in the shaft cylinder 44 of the first base 13. At the same time, the connection between the shaft cylinder 44 and the surface of the first base 13 can also strengthen the connection between the fixing member 32 and the first base 13, ensuring the installation stability of the fixing member 32 and the first base 13.

[0039] In order to make it more convenient for the first base 13 to be directly embedded in the second slide groove 31, a slider 34 is provided on one side of the part of the first base 13 that is slidably arranged in the second slide groove 31. The slider 34 is L-shaped and is arranged on one side of the bottom of the first base 13. A groove 33 is connected to one side wall of the second slide groove 31. The second slide groove 31 and the groove 33 can be a T-shaped groove or an L-shaped groove as a whole. The first base 13 can embed the slider 34 in the groove 33 by tilting, and embed the bottom of the first base 13 in the second slide groove 31. With this arrangement, it is not necessary to set openings at both ends of the second slide groove 31 for the first base 13 to be embedded in the second slide groove 31, thereby ensuring the continuity of the frames of the fixed frame 30; at the same time, the first base 13 can be directly embedded from the middle position of the second slide groove 31, which is convenient for the installation and removal of the first base 13.

[0040] In order to improve the installation firmness of the first base 13, the fixing member 32 is a threaded rod, which is threadedly connected to the first base 13. The threaded rod is inclined at one end near the slider 34 in a direction away from the fixed frame 30, so that the threaded rod is located outside the second slide groove 21 at one end near the slider 34. The threaded rod is fixed to the corresponding position of the second slide groove 31 by pressing the inner wall of the second slide groove 31 at one end away from the slider 34. The threaded rod is provided with a structure such as a hexagonal hole, a cross hole or a slotted hole at one end near the slider 34, which is convenient for operation of tools such as a screwdriver, so as to facilitate the rotation operation of the threaded rod. In the installation of small doors and windows, if the threaded rod is in a vertical state, the installer needs to get close to the fixed frame 30 to check whether the tool is aligned with the threaded rod, etc., which is troublesome. However, the end of the threaded rod of this embodiment faces outward, which is convenient for the installer standing outside the fixed frame 30 to operate the threaded rod, and is convenient for fixing the position of the first base 13, thereby improving the convenience and efficiency of installation.

[0041] Positioning plates are provided on both sides of the first base 13, and the bottom surfaces of the positioning plates on both sides are in contact with the top surface of the fixed frame 30. Under the positioning effect of the surface of the fixed frame 30, the installation position of the first base 13 is more precise, and the skew deviation of the installation of the first base 13 due to the gap between the slider 34 and the second slide groove 21 is reduced, and the axial direction of the first limiting hole 14 is guaranteed to be closer to the direction in which the first rotating shaft 11 is to be installed, thereby ensuring the precise installation of the first rotating shaft 11 and the first base 13.

[0042] The threaded rod is configured to be tapered at one end away from the slider 34, so as to adapt to the shallow second slide groove 31. The end of the threaded rod is pressed against the side wall of the second slide groove 31, so that the first base 13 can be more firmly fixed at the position corresponding to the second slide groove 21. In addition, the threaded hole structure of the first base 13 for the threaded rod to be screwed in can be formed by directly opening in the first base 13, or by embedding a nut barrel or other structure with internal threads in the first base 13.

[0043] Reference Figure 4 and Figure 5A door and window of this embodiment also includes a fixed sleeve 40, a second rotating shaft 41 and a second base 42. The fixed sleeve 40 is in the shape of a hinge plate. Unlike the movable sleeve 10, the second rotating shaft 41 is fixedly installed with the fixed sleeve 40, and the second base 42 is provided with a second limiting hole 43. The second limiting hole 43 is adapted to fit with the end of the second rotating shaft 41. The second limiting hole 43 can be directly drilled in the second base 42; or a cylindrical structure can be provided in the second base 42, and the inner wall of the cylindrical structure is used as the second limiting hole 43. Preferably, the fixed sleeve 40 can be provided with the same structure as the movable sleeve 10, can slide in the first slide groove 21 and be fixed by the locking member 22; the second base 42 can be provided with the same structure as the first base 13, and the same second slide groove 31 and groove 33 are provided at the corresponding position of the fixed frame 30. The second base 42 can be slidably provided on the corresponding side of the fixed frame 30, and is fixedly installed by an inclined threaded rod. Unifying the installation methods of the fixed shaft sleeve 40 and the movable shaft sleeve 10, the second base 42 and the first base 13 can simplify the installation operation process and improve the installation efficiency.

[0044] When installing the door and window, the fixed shaft sleeve 40 and the movable shaft sleeve 10 are respectively installed at the two end positions of the side where the door and window sash 20 needs to rotate, and the second base 42 and the first base 13 are respectively installed at the end positions of the opposite side of the fixed frame 30. It should be noted that the overall diameter or the diameter of the opening of the second limiting hole 43 can be slightly larger than the diameter of the second rotating shaft 41. The second rotating shaft 41 can be smoothly embedded in the second base 42 first, and then the first rotating shaft 11 is retracted into the movable sleeve 10 by pulling the handle part 15, and then the first rotating shaft 11 is aligned with the first limiting hole 14 and the handle part 15 is released. Under the action of the elastic member 12, the first rotating shaft 11 is extended into the first limiting hole 14, and the first base 13 is rotatably connected with the movable sleeve 10, so that the door and window sash 20 can be easily rotatably installed in the fixed frame 30; the first rotating shaft 11 is pulled out of the first limiting hole 14 by pulling the handle part 15, so that the first base 13 and the movable sleeve 10 are in a laterally separable state, and the door and window sash 20 can be easily removed by pulling the door and window sash 20 outward, thereby realizing extremely fast installation and disassembly of doors and windows.

[0045] In other embodiments, movable sleeves 10 and corresponding parts thereof may be installed at both ends of the side of the door and window sash 20 that needs to be rotated, so that the door and window sash 20 can be easily installed or removed by pulling the handles 15 on both sides.

[0046] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
