[0002] Sliding windows and doors are a common type of windows and doors that open and close via a sliding mechanism, rather than opening outward or inward like traditional casement windows or doors. Since they slide horizontally, they do not take up space indoors or outdoors, making them suitable for places with limited space.
[0003] Our company has previously applied for a utility model patent for "A lateral shift locking structure" with application number 2024202602550. The patent discloses a locking assembly for the lateral shift structure on sliding doors and windows. The main function of the lateral shift structure is to complete the lateral shift of the sliding doors and windows in the door and window frame through the action of the handle, so as to achieve the fit between adjacent sliding doors and windows or sliding doors and windows and the middle column and the door and window frame. The plug-in of the locking assembly locks the sliding doors and windows by locking on the lock of the door and window frame or the middle column, and then uses the lateral shift of the lateral shift structure to cause the locking assembly to shift to ensure better tightness of the sliding doors and windows.
[0004] Although the above patent can meet the tightness requirement of sliding doors and windows, it is limited by the structural coordination between the plug-in and the lock. The lock must be installed on the center column or the door and window frame to achieve the coordination of the locking assembly, which limits the design and installation method of the door and window frame or the center column. The design of the door and window frame and the center column must take into account the size and shape of the lock to ensure that the locking assembly can be correctly installed and operated. Therefore, the locking assembly described in the above patent brings a series of design, installation and cost challenges. Utility Model Content

DETAILED DESCRIPTION
[0031] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] Reference Figure 1-6 The sliding door and window center column locking assembly includes a center column 100 and a locking structure 300 arranged in the sliding fan 200. The center column 100 is provided with a positioning lock strip 110, and the locking structure 300 is provided with a locking hook 340. The locking hook 340 is locked on the positioning lock strip 110 through the displacement of the sliding fan 200.
[0033] The center column 100 is the central support structure of the sliding doors and windows, which provides stability and strength for the doors and windows. The positioning lock strip 110 set on the center column 100 is a key part of the locking structure. The positioning lock strip 110 provides a fixed position, which cooperates with the lock hook 340 so that the lock hook 340 can be accurately locked to achieve the locking of the doors and windows, ensuring the sealing and safety of the doors and windows. The sliding sash 200 is the active part of the sliding doors and windows, allowing the user to open or close the doors and windows by pushing and pulling. The locking structure is a component installed on the sliding sash 200, which is responsible for locking and unlocking the doors and windows. The locking structure 300 realizes the engagement or separation of the lock hook 340 and the positioning lock strip 110 through the displacement of the sliding sash 200, thereby controlling the locking state of the doors and windows.
[0034] The user moves the sliding sash 200 by pushing and pulling, and this action drives the locking structure 300 installed thereon to move together. As the sliding sash 200 moves, the locking structure 300 moves along the direction of the sliding sash. During the displacement of the locking structure 300, the locking hook 340 finally hooks onto the positioning lock strip 110 on the center column 100 to complete the preliminary locking of the center column 100 and the sliding sash 200.
[0035] In some embodiments, the end of the hook claw of the locking hook 340 has a protrusion 341 , and the inner side of the edge of the positioning locking strip 110 has a convex strip 111 , and the protrusion 341 and the convex strip 111 are engaged with each other.
[0036] The bump 341 added to the end of the hook of the lock hook 340 engages with the convex strip 111 on the inner side of the edge of the positioning lock strip 110, providing a larger contact area and a tighter fit, thereby enhancing the locking effect. The engagement relationship between the bump 341 and the convex strip 111 avoids the risk of accidental unlocking due to external force. The mutual cooperation design of the bump 341 and the convex strip 111 can effectively prevent the lock hook from being misaligned or sliding on the positioning lock strip, ensuring the safety of the door and window in the locked state.
[0037] As the lock hook 340 moves, the protrusion 341 at the end of the hook claw contacts the convex strip 111 inside the positioning lock strip 110. The design between the protrusion 341 and the convex strip 111 enables them to be embedded and engaged with each other, and this engagement action realizes the initial locking of the sliding door 200.
[0038] In some embodiments, the locking structure 300 includes a guide bar 330 , a limit bar 310 , and a transmission bar 320 that slides laterally on the limit bar 310 , wherein the locking hook 340 is disposed on the transmission bar 320 .
[0039] The guide bar 330 acts as a power component in the locking structure 300. It provides the required pulling force or pushing force for the entire locking structure 300 by linking with the side shift assembly of the handle transmission. The design of the guide bar 330 ensures the effective transmission of force and guides the entire movement process. The limit bar 310 acts as an intermediate piece. It is in sliding contact with the guide bar 330 and plays a role in transmitting and guiding power. At the same time, the limit bar also has the function of limiting the movement range of the transmission bar 320 to ensure the stability and accuracy of the locking structure 300. The transmission bar 320 is a key component in the locking structure. It receives the power of the guide bar 330 and transmits the movement. The movement of the transmission bar will drive the lock hook 340 thereon to move synchronously to achieve the locking or unlocking action.
[0040] The side shift assembly of the handle transmission is linked to the guide bar 330 to generate the required pulling force or pushing force. The guide bar 330 acts as a power piece to transmit power to the transmission bar 320. The limit bar 310 limits the guide bar 330 and the transmission bar 320. After receiving the power, the transmission bar 320 slides laterally along the guide of the limit bar 310, driving the lock hook 340 disposed thereon to move synchronously. The movement of the lock hook 340 enables it to further engage or disengage with the positioning lock bar 110 on the center column 100, thereby achieving a more stable locking or quick unlocking of the sliding door 200.
[0041] In some embodiments, a mounting block 321 is provided on the back of the transmission bar 320, and a wedge-shaped hole 322 is provided in the mounting block 321; a limiting straight hole 311 corresponding to the wedge-shaped hole 322 is provided in the limiting bar 310, and a slider 331 is provided on the guide bar 330, and the slider 331 slides through the limiting straight hole 311 and extends into the wedge-shaped hole 322.
[0042] The design of the wedge-shaped hole 322 enables the linear motion of the slider 331 to be converted into the lateral motion of the mounting block 321. The lateral motion of the mounting block 321 can enhance the locking force between the lock hook 340 and the positioning lock bar 110. The limiting straight hole 311 provides guidance and limitation for the linear motion of the slider 331, ensuring the accuracy and consistency of the motion direction. The lateral sliding relationship between the transmission bar 320 and the limiting bar 310 enables the lateral motion of the mounting block 321 to be transmitted to the transmission bar 320.
[0043] In some embodiments, a plurality of side shift pulleys 324 are disposed on the back of the transmission bar 320 , and a side shift guide groove 314 for cooperating with the side shift pulleys 324 to roll is disposed on the limiting bar 310 .
[0044] The side shift pulley 324 is arranged on the back of the transmission bar 320 to reduce friction when the transmission bar slides along the limit bar 310. The side shift guide groove 314 is arranged on the limit bar 310 and cooperates with the side shift pulley 324 to provide stable guidance for the transmission bar 320.
[0045] When the guide bar 330 performs linear motion through the slider 331, the motion is converted into lateral motion of the transmission bar 320 through the cooperation of the mounting block 321 and the wedge-shaped hole 322. The side shift pulley 324 on the back of the transmission bar 320 rolls in the side shift guide groove 314 on the limit bar 310, ensuring that the transmission bar 320 moves stably along the predetermined path when moving laterally, and preventing deviation or vibration caused by friction.
[0046] In some embodiments, a plurality of guide ribs 313 are disposed on the limit bar 310 , and a guide groove 323 for slidingly cooperating with the guide ribs 313 is disposed on the back of the transmission bar 320 .
[0047] The guide rib 313 is arranged on the limit bar 310, providing an additional guide and positioning point to ensure that the transmission bar 320 maintains stability and linear motion during the sliding process, and prevents the transmission bar from deflecting or tilting. The guide groove 323 is arranged on the back of the transmission bar 320, and cooperates with the guide rib 313 to provide a sliding track for the transmission bar. The design of the guide groove helps to reduce the friction and wear of the transmission bar during the movement.
[0048] When the transmission bar 320 moves laterally, the guide groove 323 on its back interacts with the guide rib 313 on the limit bar 310 to ensure that the transmission bar slides stably in a straight line. The cooperation between the guide groove 323 and the guide rib 313 ensures the synchronous movement of the transmission bar 320, so that the lock hook 340 can accurately reach the predetermined position on the positioning lock bar 110.
[0049] In some embodiments, a boss 312 with a sliding groove is provided on the upper and lower sides of the limit bar 310 , and the upper and lower ends of the transmission bar 320 slide in the sliding groove of the boss 312 .
[0050] The boss 312 is arranged on the upper and lower sides of the limit bar 310, and a slide groove is configured thereon. The boss plays a supporting and guiding role, providing a stable sliding path for the transmission bar 320. The slide groove is a groove on the boss 312, which allows the upper and lower ends of the transmission bar 320 to slide inside it. The design of the slide groove ensures the smooth movement of the transmission bar in the vertical direction and limits its range of movement in the horizontal direction. The upper and lower ends of the transmission bar slide in the slide groove of the boss 312. This design allows the transmission bar to move along the length direction of the limit bar while maintaining stability in the vertical direction.
[0051] The transmission bar 320 slides in the horizontal direction on the limiting bar 310, and the slide groove on the boss 312 ensures the stability of the transmission bar in the horizontal direction, thereby achieving precise horizontal movement.
[0052] In some embodiments, a plurality of first racks 325 are disposed on the transmission bar 320 , and a second rack 342 meshing with the first racks 325 is disposed on the back of the locking hook 340 .
[0053] The plurality of first racks 325 disposed on the transmission bar 320 provide a mechanical engagement mechanism, which can engage with the second rack 342 on the back of the lock hook 340 to ensure accurate positioning and synchronous movement of the lock hook at a specific position. The second rack 342 is disposed on the back of the lock hook 340 and engages with the first rack 325 to achieve precise control of the position of the lock hook and prevent the lock hook from being unlocked or moved at an unexpected position.
[0054] The meshing of the racks also has the function of preventing reverse movement, that is, after the lock hook 340 is locked with the first rack 325 of the transmission bar 320 through the second rack 342, even if there is an external force, the lock hook 340 can be prevented from sliding in the opposite direction, thereby improving the safety of the locking structure.
[0055] In some embodiments, an adapting groove 326 is provided on the back side of the transmission bar 320 , wherein both the front and back sides of the mounting block 321 can be adapted in the adapting groove 326 .
[0056] The adaption groove 326 is arranged on the back of the transmission bar 320, providing a groove structure that can adapt to the front and back sides of the mounting block 321. This design allows the mounting block 321 to match the transmission bar 320 in both directions, increasing the flexibility and adaptability of the installation. Since the wedge-shaped hole 322 on the mounting block 321 can be adjusted in direction, the operator can select the most suitable installation direction according to the specific installation location and use environment, thereby improving the adaptability and flexibility of the locking structure.
[0057] The operator selects the best direction of the wedge-shaped hole 322 on the mounting block 321 according to the installation space and force transmission requirements. The mounting block 321 is adapted to the adaption groove 326 on the back of the transmission bar 320 to ensure that the direction of the wedge-shaped hole 322 is consistent with the required force transmission direction.
[0058] like Figure 7 As shown, a locking plate 120 can be installed at the positioning locking strip 110 . The locking plate 120 is mainly fixed by screws to meet the requirement of fastening the locking plate 120 . The locking plate 120 can be locked with the locking hook 340 to complete the locking.
[0059] like Figure 5 and 8 As shown, the wedge-shaped hole 322 and the slider 311 can be structures of different shapes, for example, Figure 5 In the embodiment, the wedge-shaped hole 322 may be a hole with a circular arc design, and the slider 311 is a sleeve, a bearing or a shaft for fitting the circular arc wedge-shaped hole 322. Figure 8In the embodiment, the wedge-shaped hole 322 may have an angular hole design, and the slider 311 is a parallelogram or rectangular block for adapting to the angular structure.
[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
