Description

Technical Field

[0001] The invention relates to the technical field of doors and windows, and in particular to an inner-outer opening and sliding door and window. Background Art

[0002] Doors and windows are important components of indoor lighting and ventilation. The commonly used types of doors and windows in the relevant technology are usually casement doors and windows and sliding doors and windows. Casement doors and windows are opened and closed by rotating along a certain direction on one axis, and are divided into two types: inward opening and outward opening. Their advantages are: simple structure, large opening area, and excellent ventilation and sealing effects. Among them, the inward opening casement windows are convenient for window cleaning, and the outward opening casement windows do not occupy indoor space when opening; the disadvantage is that the window width is not large, and the window sash is easily damaged in windy weather. Sliding windows are windows that are installed in the track of the window frame and pushed and pulled to open and close. Their advantages are: no indoor and outdoor space is occupied, simple structure, easy operation, large window width, good lighting, and long service life; the disadvantage is that general sliding doors and windows can only be opened halfway, not fully opened, which limits the passage position.

[0003] With the development of door and window technology, doors and windows that can be opened and pushed are now available on the market. However, these doors and windows can usually only be opened in one direction, that is, they can only be opened inwards or outwards. The opening method is single and inconvenient to use. Moreover, when these doors and windows are opened outwards, they are inconvenient to wipe. Although some doors and windows can be opened and pushed inwards and outwards, most of them have complex structures and need to cooperate with motors or manually pull pins to switch between opening and pushing.

[0004] The technical problem to be solved by the present invention is: how to provide a door and window which has a simple structure and is easy to use and can be opened both inside and outside and can be pushed and pulled. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide an internal and external opening and sliding door and window, which has the characteristics of simple structure and convenient use, and can also realize the functions of internal and external opening and sliding of the fan body.

[0006] The technical solution adopted by the present invention is: an internal and external casement sliding door and window, comprising a frame, a fan assembly and a track assembly respectively mounted on the frame, the track assembly comprising a fixed rail fixedly connected to the frame and a movable rail rotatably connected to the frame, a first guide rail being arranged on the movable rail, a second guide rail corresponding to the first guide rail being arranged on the fixed rail, the fan assembly comprising a first fan and a second fan, the first fan being fixedly connected to the movable track, the second fan being slidably connected to the first guide rail and the second guide rail, and further comprising a locking mechanism;

[0007] The locking mechanism includes a movable lock box installed on one end of the movable rail close to the fixed rail and an opening and closing assembly installed on the movable lock box, the movable lock box is provided with a first lock hole connected to the first guide rail, the opening and closing assembly includes a trigger member and a blocking member that cooperate with the transmission, one end of the trigger member is built into the movable lock box, the other end extends toward the fixed rail and protrudes from the movable lock box, a first reset member is provided between the trigger member and the movable lock box, one end of the blocking member is built into the movable lock box, the other end extends toward the first lock hole, and a second reset member is provided between the blocking member and the movable lock box;

[0008] The movable rail is docked with the fixed rail, and the fixed rail drives the trigger member to retract into the movable lock box, driving the blocking member to withdraw from the first lock hole; the movable rail is separated from the fixed rail, and the first reset member drives one end of the trigger member to extend out of the movable lock box, and the second reset member drives one end of the blocking member to extend into the first lock hole.

[0009] The inside-outside casement sliding door and window of the present application, when the movable rail and the fixed rail are docked in place, the fixed rail will press the trigger member back into the movable lock box, thereby driving the blocking member to withdraw from the first lock hole, the first guide rail is connected to the second guide rail, and the second fan body can slide freely in the first guide rail and the second guide rail, at this time the door and window are in a push-pull state; when the first fan body and the second fan body are overlapped, the first fan body, the second fan body and the movable rail can be rotated around the frame body, at this time the door and window are in a casement open state, after the movable rail is separated from the fixed rail, under the drive of the second reset member, the blocking member extends into the first lock hole, which can prevent the second fan body from sliding out of the first guide rail to cause a safety accident, thereby improving the reliability of the door and window;

[0010] Since the trigger member is retracted into the movable lock box by docking the movable rail with the fixed rail, and then drives the blocking member to withdraw from the first lock hole, the trigger member can be driven to retract regardless of whether the movable rail rotates from the inside or the outside of the frame to dock with the fixed rail, that is, the inside-outside and outside-side opening of the door and window can be achieved, and the switching between the inside-outside and inside-outside opening and the push-pull state does not require the aid of a motor or manual insertion and removal of a latch, the operation is convenient, the structure is simple and compact, and the opening methods are diversified to meet the different needs of users.

[0011] In some embodiments, the locking mechanism also includes a fixed lock box installed on the fixed rail near one end of the movable rail, the fixed lock box is provided with a second lock hole connected to the second guide rail, and a first guide surface and a second guide surface are provided on one side of the fixed lock box near the movable lock box, one end of the first guide surface is connected to the second guide surface, and the other end extends toward the side of the fixed rail, and the distance between the first guide surface and the movable lock box gradually increases from one end close to the second guide surface to the other end, and the other end of the second guide surface extends toward the other side of the fixed rail, and the distance between the second guide surface and the movable lock box gradually increases from one end close to the first guide surface to the other end.

[0012] By adopting the above technical solution, by setting the first guide surface and the second guide surface, when the movable rail and the fixed rail approach or separate from each other, one end of the trigger member protruding from the movable lock box will maintain contact with the first guide surface or the second guide surface, so that the trigger member gradually retracts or extends, thereby avoiding the trigger member from getting stuck and causing damage to the doors and windows.

[0013] In some embodiments, the first guide surface is connected to the second guide surface via a positioning groove, and the positioning groove matches with the top of the trigger member.

[0014] By adopting the above technical solution, when the movable rail and the fixed rail are docked in place, one end of the movable lock box protruding from the trigger member just falls into the positioning groove, which can improve the positioning accuracy when the movable rail and the fixed rail are docked.

[0015] In some embodiments, the locking mechanism further includes an anti-falling assembly, and the anti-falling assembly includes an anti-falling block and an anti-falling groove that are inserted into each other;

[0016] The anti-fall block is arranged on a side of the fixed lock box close to the movable lock box, and the anti-fall groove is arranged on a side of the movable lock box close to the fixed lock box; or

[0017] The anti-falling block is arranged on a side of the movable lock box close to the fixed lock box, and the anti-falling groove is arranged on a side of the fixed lock box close to the movable lock box.

[0018] By adopting the above technical scheme, the accuracy of the docking between the movable rail and the fixed rail can be improved through the cooperation of the anti-fall block and the anti-fall groove. It can also provide a support point for the first fan body, the second fan body and the movable rail, improve the stress conditions of the first fan body, the second fan body and the movable rail, avoid falling due to their own gravity, improve the reliability of doors and windows, and extend the service life of doors and windows.

[0019] In some embodiments, the anti-falling groove is provided on a side of the movable lock box away from the first lock hole, a side of the movable lock box close to the first lock hole is provided with an air avoidance groove corresponding to the anti-falling block, and a cover plate corresponding to the air avoidance groove is provided on the fixed lock box; or

[0020] The anti-falling groove is arranged on the side of the fixed lock box away from the second lock hole, the side of the fixed lock box close to the second lock hole is provided with an air avoidance groove corresponding to the anti-falling block, and the movable lock box is provided with a cover plate corresponding to the air avoidance groove.

[0021] By adopting the above technical solution, by opening an avoidance groove, it is possible to prevent the anti-fall block from interfering with its corresponding movable lock box or fixed lock box during the docking or separation of the movable rail and the fixed rail. By providing a cover plate, when the movable rail and the fixed rail are docked in place, the cover plate can cover the avoidance groove to enhance the beauty of the doors and windows.

[0022] In some embodiments, the locking mechanism further includes a safety component, which includes an anti-slipping piece and an anti-slipping groove that cooperate with each other. When the movable rail is docked with the fixed rail, the anti-slipping piece is stuck in the anti-slipping groove; when an external force greater than a preset value is applied, the anti-slipping piece exits the anti-slipping groove, and the movable rail is separated from the fixed rail.

[0023] The anti-slipping member is connected to the side of the movable lock box close to the fixed lock box in a floating manner, and the anti-slipping groove is arranged on the side of the fixed lock box close to the movable lock box; or

[0024] The anti-slipping piece is floatingly connected to a side of the fixed lock box close to the movable lock box, and the anti-slipping groove is arranged on a side of the movable lock box close to the fixed lock box.

[0025] By adopting the above technical solution, the anti-slip part cooperates with the anti-slip groove to prevent the movable rail from easily separating after being docked with the fixed rail. Only when the movable rail is subjected to a force greater than the combining force of the anti-slip part and the anti-slip groove can it be separated from the fixed rail, thereby improving the safety of doors and windows.

[0026] In some embodiments, the safety component further includes a third reset member, one end of the anti-slip member is movably connected to the fixed lock box, and the other end is protruded toward the movable lock box. The third reset member keeps one end of the anti-slip member protruding from the fixed lock box.

[0027] By adopting the above technical solution, when the movable rail and the fixed rail are docked in place, the elastic force of the anti-slip part is applied by the third reset part, so that the anti-slip part and the anti-slip groove can remain engaged, preventing the movable rail from being easily separated from the fixed rail. Only when the external force applied to the movable rail is greater than the elastic force of the third reset part, can the movable rail be separated from the fixed rail, thereby improving the safety of doors and windows.

[0028] In some embodiments, the safety component also includes a first magnetic component and a second magnetic component, one end of the anti-dropping component is movably connected to the fixed lock box, and the other end is protruded toward the movable lock box. The first magnetic component is built into the anti-dropping component, and the second magnetic component is arranged on the movable lock box opposite to the first magnetic component. The first magnetic component and the second magnetic component are magnetically attracted to each other so that the anti-dropping component remains engaged with the anti-dropping groove.

[0029] By adopting the above technical solution, when the movable rail and the fixed rail are docked in place, the first magnetic part and the second magnetic part are magnetically attracted to each other so that the anti-slip part and the anti-slip groove remain engaged, thereby preventing the movable rail and the fixed rail from being easily separated. The movable rail and the fixed rail can only be separated when the external force applied is greater than the magnetic force of mutual attraction between the first magnetic part and the second magnetic part.

[0030] In some embodiments, a hanging pulley is connected to the top of the second fan body, and the hanging pulley is slidably connected to the first guide rail and the second guide rail.

[0031] By adopting the above technical solution, the hanging pulley cooperates with the first guide rail and the second guide rail to reduce the resistance of the second fan body when sliding and limit the sliding trajectory of the second fan body, making the doors and windows smoother when pushed and pulled, and improving the user experience.

[0032] In some embodiments, the trigger member and the blocking member are transmitted through inclined surface cooperation.

[0033] By adopting the above technical solution, the direction of the force can be changed through the transmission of the inclined surface, so that the trigger member can be retracted away from the fixed rail to drive the blocking member to withdraw from the first lock hole.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0048] See also Figures 1 to 10, which is a preferred embodiment of the present invention, an inside-outside casement sliding door and window 100, includes a frame 10, a fan assembly 30 respectively mounted on the frame 10, a track assembly 20 and a locking mechanism 40, the track assembly 20 includes a fixed rail 22 fixed to the frame 10 and a movable rail 21 rotatably connected to the frame 10, the movable rail 21 is provided with a first guide rail 211, the fixed rail 22 is provided with a second guide rail 221 corresponding to the first guide rail 211, the fan assembly 30 includes a first fan body 31 and a second fan body 32, the first fan body 31 is fixed to the movable rail 21, and the second fan body 32 is slidably connected to the first guide rail 211 and the second guide rail 221. The locking mechanism 40 is used to control the combination or separation of the movable rail 21 and the fixed rail 22. The locking mechanism 40 includes a movable lock box 41 installed on the movable rail 21 near one end of the fixed rail 22 and an opening and closing component 43 installed on the movable lock box 41. The movable lock box 41 is provided with a first lock hole 411 connected to the first guide rail 211. The opening and closing component 43 includes a trigger member 431 and a blocking member 433 of transmission cooperation. One end of the trigger member 431 is built into the movable lock box 41, and the other end extends toward the fixed rail 22 and protrudes from the movable lock box 41. A first reset member 432 is provided between the trigger member 431 and the movable lock box 41. One end of the blocking member 433 is built into the movable lock box 41, and the other end extends toward the first lock hole 411. A second reset member 434 is provided between the blocking member 433 and the movable lock box 41. The movable rail 21 is docked with the fixed rail 22, and the fixed rail 22 drives the trigger member 431 to retract into the movable lock box 41, driving the blocking member 433 to withdraw from the first lock hole 411; the movable rail 21 is separated from the fixed rail 22, and the first reset member 432 drives one end of the trigger member 431 to extend out of the movable lock box 41, and the second reset member 434 drives one end of the blocking member 433 to extend into the first lock hole 411.

[0049] In the inside-outside casement sliding door and window 100 of the present application, when the movable rail 21 and the fixed rail 22 are docked in place, the fixed rail 22 will press the trigger member 431 back into the movable lock box 41, thereby driving the blocking member 433 to withdraw from the first lock hole 411, the first guide rail 211 and the second guide rail 221 are connected, and the second fan body 32 can slide freely in the first guide rail 211 and the second guide rail 221, at this time, the door and window are in a push-pull state; when the first fan body 31 and the second fan body 32 overlap, the first fan body 31, the second fan body 32 and the movable rail 21 can be rotated around the frame 10, at this time, the door and window are in a casement open state, and after the movable rail 21 is separated from the fixed rail 22, under the drive of the second reset member 434, the blocking member 433 extends into the first lock hole 411, which can prevent the second fan body 32 from sliding out of the first guide rail 211 and causing a safety accident, thereby improving the reliability of the door and window. Since the trigger member 431 is retracted into the movable lock box 41 by docking the movable rail 21 with the fixed rail 22, thereby driving the blocking member 433 to exit the first lock hole 411, no matter whether the movable rail 21 rotates from the inside or the outside of the frame 10 to dock with the fixed rail 22, the trigger member 431 can be driven to retract, that is, the inside-outside and outside-side opening of the door and window can be realized, and the switching between the inside-outside and inside-outside opening and the push-pull state does not require the aid of a motor or manual insertion and removal of a latch, the operation is convenient, the structure is simple and compact, and the opening methods are diversified to meet the different needs of users.

[0050] like Figure 2 As shown, the movable rail 21 is rotatably connected to the frame 10 via a rotating shaft 212. In order to improve the stability of the first fan body 31 when it is opened horizontally, the bottom of the first fan body 31 is connected to the frame 10 via a ground hinge 33. In this way, there are two hinge points between the first fan body 31 and the frame 10, which can withstand a greater weight and make the door and window structure more stable. In other embodiments, hinges can also be set between the side of the first fan body 31 and the frame 10 to further improve the load-bearing capacity of the doors and windows.

[0051] It should be noted that, although the first fan body 31 and the second fan body 32 shown in the drawings of the present application both have frames, the first fan body 31 and the second fan body 32 may also be a frameless pure glass structure.

[0052] Please refer to Figure 2 The top of the second fan body 32 is connected with a hanging pulley 321, and the hanging pulley 321 is slidably connected with the first guide rail 211 and the second guide rail 221. By cooperating with the hanging pulley 321 and the first guide rail 211 and the second guide rail 221, the resistance of the second fan body 32 when sliding can be reduced, and the sliding track of the second fan body 32 can be limited, so that the door and window can be pushed and pulled more smoothly, and the user experience can be improved.

[0053] Preferably, in order to further prevent the first fan body 31 and the second fan body 32 from sliding relative to each other in the open state and causing impact on the blocking member 433, thereby affecting the user experience of the door and window, an anti-separation mechanism can be set between the first fan body 31 and the second fan body 32. For example, a magnetic strip is set between the first fan body 31 and the second fan body 32 to prevent the first fan body 31 and the second fan body 32 from sliding relative to each other when they are opened horizontally by magnetic attraction. The first fan body 31 and the second fan body 32 can also be prevented from separating by setting relevant card-connecting or plug-in components.

[0054] like Figure 6 and Fig. 9 As shown, the locking mechanism 40 also includes a fixed lock box 42 installed on one end of the fixed rail 22 close to the movable rail 21, and the fixed lock box 42 is provided with a second lock hole 421 connected to the second guide rail 221, and the fixed lock box 42 is provided with a first guide surface 435 and a second guide surface 436 on one side of the movable lock box 41 close to the movable lock box 41, one end of the first guide surface 435 is connected to the second guide surface 436, and the other end extends toward the side of the fixed rail 22, and the distance between the first guide surface 435 and the movable lock box 41 gradually increases from one end close to the second guide surface 436 to the other end, and the other end of the second guide surface 436 extends toward the other side of the fixed rail 22, and the distance between the second guide surface 436 and the movable lock box 41 gradually increases from one end close to the first guide surface 435 to the other end. By setting the first guide surface 435 and the second guide surface 436, when the movable rail 21 and the fixed rail 22 approach or separate from each other, one end of the trigger member 431 protruding from the movable lock box 41 will maintain contact with the first guide surface 435 or the second guide surface 436, so that the trigger member 431 gradually retracts or extends, thereby preventing the trigger member 431 from getting stuck and causing damage to doors and windows.

[0055] Furthermore, in order to reduce the friction between the trigger member 431 and the first guide surface 435 and the second guide surface 436, so as to reduce noise and extend the service life of doors and windows, the end of one end of the trigger member 431 protruding from the movable lock box 41 is an outwardly protruding arc surface or inclined surface, so that when the trigger member 431 contacts the first guide surface 435 or the second guide surface 436, it is a line contact, which can reduce friction.

[0056] Preferably, the first guide surface 435 and the second guide surface 436 are connected by a positioning groove 437, and the positioning groove 437 matches the top of the trigger member 431. When the movable rail 21 and the fixed rail 22 are docked in place, one end of the movable lock box 41 protruding from the trigger member 431 just falls into the positioning groove 437, which can improve the positioning accuracy when the movable rail 21 and the fixed rail 22 are docked. Optionally, the shape of the positioning groove 437 should match the end surface of the end of the movable lock box 41 protruding from the trigger member 431, and is preferably a "U"-shaped groove or a "V"-shaped groove.

[0057] In this embodiment, the blocking member 433 enters and exits the first lock hole 411 from the side of the first lock hole 411. In other embodiments, the blocking member 433 can also enter and exit the first lock hole 411 from the top of the first lock hole 411, that is, the specific positions of the blocking member 433 and the trigger member 431 on the movable lock box 41 can be flexibly set according to the spatial layout of the movable lock box 41.

[0058] In this embodiment, the trigger member 431 and the blocking member 433 are driven by the inclined plane matching. The inclined plane matching transmission can change the direction of the force, so that the trigger member 431 retracts away from the fixed rail 22 and drives the blocking member 433 to withdraw from the first lock hole 411.

[0059] Specifically, Figure 7 and Figure 8 As shown, in this embodiment, one end of the trigger member 431 built into the movable lock box 41 is provided with a first inclined surface 4311, and one end of the blocking member 433 built into the movable lock box 41 is provided with a second inclined surface 4331 matched with the first inclined surface 4311. In other embodiments, other transmission modes can also be used to achieve the same function, for example, a rack is provided at one end of the trigger member 431 and the movable lock box 41 built into the blocking member 433, and the rack between the two is driven by a gear or a worm, so that the trigger member 431 is retracted to drive the blocking member 433 to withdraw from the first lock hole 411; or one end of the movable lock box 41 built into the blocking member 433 can be connected to the movable lock box 41 through a flexible member, and then one end of the movable lock box 41 built into the trigger member 431 abuts against the flexible member, and the trigger member 431 retracts into the movable lock box 41 to drive the flexible member to bend, thereby driving the blocking member 433 to withdraw from the first lock hole 411.

[0060] In this embodiment, the first return member 432 and the second return member 434 are both compression springs. In other embodiments, the first return member 432 and the second return member 434 can also be set as elastic members such as tension springs, spring sheets, and elastic rubber that can achieve the same function.

[0061] like Figure 5 and Figure 6 As shown, in order to improve the docking accuracy between the fixed rail 22 and the movable rail 21, the locking mechanism 40 further includes an anti-falling assembly 44, and the anti-falling assembly 44 includes an anti-falling block 441 and an anti-falling groove 442 that are inserted into each other;

[0062] The anti-falling block 441 is arranged on a side of the fixed lock box 42 close to the movable lock box 41, and the anti-falling groove 442 is arranged on a side of the movable lock box 41 close to the fixed lock box 42; or

[0063] The anti-falling block 441 is arranged on a side of the movable lock box 41 close to the fixed lock box 42 , and the anti-falling groove 442 is arranged on a side of the fixed lock box 42 close to the movable lock box 41 .

[0064] By cooperating with the anti-fall block 441 and the anti-fall groove 442, the accuracy of the docking between the movable rail 21 and the fixed rail 22 can be improved, and a support point can be provided for the first fan body 31, the second fan body 32 and the movable rail 21, thereby improving the stress conditions of the first fan body 31, the second fan body 32 and the movable rail 21, avoiding the phenomenon of falling due to their own gravity, and improving the reliability of doors and windows and extending the service life of doors and windows.

[0065] In this embodiment, the first guide surface 435, the positioning groove 437 and the second guide surface are arranged on the inner side of the anti-fall groove 442, and the trigger member 431 is protrudingly provided with an anti-fall block 441, which can make the structure of the locking mechanism 40 more compact and help to reduce the volume of the locking mechanism 40. In other embodiments, when the space of the fixed lock box 42 or the movable lock box 41 permits, the anti-fall block 441 and the trigger member 431 can also be separated and arranged at different positions.

[0066] Furthermore, both ends of the anti-fall block 441 are provided with outwardly protruding arc-shaped or acute-angled introduction surfaces, that is, the width of the two ends of the anti-fall block 441 is smaller than the width of the middle part. This arrangement can facilitate the insertion of the anti-fall block 441 and the anti-fall groove 442, and can also reduce the assembly accuracy requirements during the door and window installation production process.

[0067] Preferably, the anti-falling groove 442 is arranged on a side of the movable lock box 41 away from the first lock hole 411, a side of the movable lock box 41 close to the first lock hole 411 is provided with an air-avoiding groove 443 corresponding to the anti-falling block 441, and a cover plate 444 corresponding to the air-avoiding groove 443 is arranged on the fixed lock box 42; or

[0068] The anti-falling groove 442 is arranged on a side of the fixed lock box 42 away from the second lock hole 421 , and a side of the fixed lock box 42 close to the second lock hole 421 is provided with an avoidance groove 443 corresponding to the anti-falling block 441 , and a cover plate 444 corresponding to the avoidance groove 443 is arranged on the movable lock box 41 .

[0069] By providing the avoidance groove 443, the anti-fall block 441 can be prevented from interfering with its corresponding movable lock box 41 or fixed lock box 42 during the docking or separation of the movable rail 21 and the fixed rail 22. By providing the cover plate 444, when the movable rail 21 and the fixed rail 22 are docked in place, the cover plate 444 can cover the avoidance groove 443 to enhance the beauty of the doors and windows.

[0070] In order to further improve the reliability of the inside-outside casement sliding door and window 100, the locking mechanism 40 further includes a safety component 45, which includes an anti-slipping piece 451 and an anti-slipping groove 452 that cooperate with each other. When the movable rail 21 and the fixed rail 22 are docked, the anti-slipping piece 451 is stuck in the anti-slipping groove 452; when an external force greater than a preset value is applied, the anti-slipping piece 451 exits the anti-slipping groove 452, and the movable rail 21 is separated from the fixed rail 22;

[0071] The anti-dropping member 451 is floatingly connected to a side of the movable lock box 41 close to the fixed lock box 42, and the anti-dropping groove 452 is provided on a side of the fixed lock box 42 close to the movable lock box 41; or

[0072] The anti-slip member 451 is floatingly connected to a side of the fixed lock box 42 close to the movable lock box 41 , and the anti-slip groove 452 is provided on a side of the movable lock box 41 close to the fixed lock box 42 .

[0073] The cooperation between the anti-slip piece 451 and the anti-slip groove 452 can prevent the movable rail 21 from being easily separated from the fixed rail 22 after being docked. Only when the movable rail 21 is subjected to a force greater than the combining force between the anti-slip piece 451 and the anti-slip groove 452 can it separate from the fixed rail 22, thereby improving the safety of doors and windows.

[0074] In this embodiment, the safety component 45 further includes a third reset member 453. One end of the anti-slip member 451 is movably connected to the fixed lock box 42, and the other end is protruded toward the movable lock box 41 by the fixed lock box 42. The third reset member 453 allows one end of the anti-slip member 451 to remain protruded from the fixed lock box 42. When the movable rail 21 and the fixed rail 22 are docked in place, the elastic force of the anti-slip member 451 is applied by the third reset member 453, so that the anti-slip member 451 and the anti-slip groove 452 are kept engaged, preventing the movable rail 21 from being easily separated from the fixed rail 22. Only when the external force on the movable rail 21 is greater than the elastic force of the third reset member 453, the movable rail 21 can be separated from the fixed rail 22, thereby improving the safety of the door and window. Optionally, the third reset member 453 is a compression spring and the anti-slip member 451 is a steel ball. In other embodiments, the third reset member 453 can also be set as an elastic member that can achieve the same function, and the anti-slip member 451 can also be set as a cylinder or a polygonal column, but the end that convexly fixes the lock box 42 should be set as an outwardly protruding arc surface or inclined surface, and the anti-slip member 451 can also be directly set as a ball-end screw.

[0075] In this embodiment, the anti-slip groove 452 is arranged on the side of the anti-falling block 441, so that the structure of the locking mechanism 40 can be more compact. In other embodiments, if the structure allows, the anti-slip groove 452 can also be arranged separately from the anti-falling block 441. In this embodiment, the anti-slip member 451 is arranged on the side of the anti-falling block 441, that is, the anti-slip member 451 is arranged parallel to the end face of the movable lock box 41. In other embodiments, the anti-slip member 451 can also be arranged on the end face of the anti-falling block 441, that is, the anti-slip member 451 is arranged perpendicular to the end face of the movable lock box 41.

[0076] In order to facilitate the anti-slipping member 451 to be inserted into the anti-slipping groove 452 or the anti-slipping member 451 to be withdrawn from the anti-slipping groove 452, the anti-slipping groove 452 is preferably a "U"-shaped groove or a "V"-shaped groove.

[0077] Furthermore, in order to adjust the compression amount of the third reset member 453 so as to change the binding force between the anti-slip member 451 and the anti-slip groove 452, an adjusting member 454 is also provided at the end of the third reset member 453 away from the anti-slip member 451, and the adjusting member 454 is threadedly connected to the fixed lock box 42. The compression amount of the third reset member 453 can be adjusted by adjusting the depth of the adjusting member 454 screwed into the fixed lock box 42.

[0078] like Fig.10 As shown, another locking mechanism 40 solution provided by the internal and external casement sliding door and window 100 of the present application is provided, in which the third reset member 453 is replaced by the first magnetic member 455 and the second magnetic member 456. The safety component 45 also includes the first magnetic member 455 and the second magnetic member 456, one end of the anti-slip member 451 is movably connected to the fixed lock box 42, and the other end is protruded toward the movable lock box 41 to fix the lock box 42, the first magnetic member 455 is built into the anti-slip member 451, and the second magnetic member 456 is arranged on the movable lock box 41 opposite to the first magnetic member 455, and the first magnetic member 455 and the second magnetic member 456 are magnetically attracted to each other so that the anti-slip member 451 and the anti-slip groove 452 remain engaged. When the movable rail 21 and the fixed rail 22 are docked, the first magnetic member 455 and the second magnetic member 456 are magnetically attracted to each other so that the anti-slip member 451 and the anti-slip groove 452 remain engaged, preventing the movable rail 21 and the fixed rail 22 from being easily separated. The movable rail 21 and the fixed rail 22 can only be separated when the applied external force is greater than the magnetic force of the first magnetic member 455 and the second magnetic member 456. The above safety components 45 can be used alone or in combination.

[0079] Optionally, both the first magnetic member 455 and the second magnetic member 456 may be configured as permanent magnets, or one of the first magnetic member 455 and the second magnetic member 456 may be configured as a magnet and the other may be configured as an iron block.

[0080] In the push-pull state, the movable rail 21 and the fixed rail 22 are docked in place, and the fixed lock box 42 will press the trigger member 431 back into the movable lock box 41, thereby driving the blocking member 433 to exit the first lock hole 411. The first lock hole 411, the second lock hole 421, the first guide rail 211 and the second guide rail 221 are connected, and the second fan body 32 can slide freely in the first guide rail 211 and the second guide rail 221. At this time, the door and window are in a push-pull state. When in the horizontally opened state, the second fan body 32 is first pushed to overlap with the first fan body 31, and then the first fan body 31, the second fan body 32 and the movable rail 21 can be rotated around the rotating shaft 212 and the ground hinge 33 toward the inside or outside of the frame 10. At this time, the door and window are in the horizontally opened state, and when the movable rail 21 is separated from the fixed rail 22, under the drive of the second reset member 434, the blocking member 433 extends into the first lock hole 411, which can prevent the second fan body 32 from slipping out of the first guide rail 211 and causing a safety accident, thereby improving the reliability of the door and window.

[0081] Finally, it should be noted that the above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
