[0041] The technical scheme of the utility model will be described clearly and completely below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0042] Referring to Figures 1-9 A side displacement locking structure, comprising a bearing piece 100, a plug-in 200 and a lock piece 300, the plug-in 200 comprises a positioning seat 210 arranged on the top cover plate 110 of the bearing piece 100, and the positioning seat 210 is provided with a flat head screw 220 in the middle; the inside of the positioning seat 210 is provided with a movable hole 211, and the flat head screw 220 penetrates and extends to both sides of the movable hole 211; the movable hole 211 comprises a first through hole 211a and a second through hole 211b, and the positioning seat 210 is provided with a positioning groove 211c at the first through hole 211a, and the external thread of the flat head screw 220 is provided with a positioning block 221 which is slidably matched in the positioning groove 211c; the flat head screw 220 is externally provided with an elastic member 222 abutting against the positioning block 123 at one end and abutting against the adjacent inner wall of the first through hole 211a and the second through hole 211b at the other end.

[0043] By setting the movable hole 211 inside the positioning seat 210, the flat head screw 220 can be fine-tuned inside the movable hole 211 to adapt to different installation requirements and gap compensation. The setting of the elastic member 222 provides elastic buffering, which helps to reduce the stress concentration of the locking structure caused by installation errors or slight deformation during use, thereby improving the durability and reliability of the structure. The design of the elastic member 222 also allows the flat head screw 220 to have a certain elastic deformation space during locking, which helps to reduce resistance during installation and disassembly, making the operation more convenient.

[0044] Position allocation of the plug-in 200, the carrier 100 and the lock 300: the plug-in 200 is fixed on the side of the first sash through the carrier 100 and the side displacement structure (such as the pulling part in the background technology mentioned in the application number 2023224682882, a sliding door and window gap compensation assembly), and the lock 300 is fixed on the front of the second sash or the column of the window frame.

[0045] Installation process of the plug-in 200: install the elastic member 222 in the movable hole 211, and insert it into the first through hole 211a from the front. Then insert the positioning block 221 into the positioning groove 211c from the bottom of the positioning seat 210. During this process, one side of the positioning block 221 needs to push one side of the elastic member 222, so that it is compressed in the direction of the second through hole 211b, until the positioning block 221 is completely inserted into the positioning groove 211c. Then install the flat head screw 220 in the movable hole 211 of the positioning seat 210, insert it from the second through hole 211b side and push it in the direction of the first through hole 211a, until it contacts the positioning block 221, then screw the tail of the flat head screw 220 with the positioning block 221.

[0046] When the sash moves to the point where the flat head screw 220 engages with the lock 300, some stress can occur due to friction, installation errors, or external impacts. The elastic member 222 is designed to absorb these stresses and prevent direct force from acting on the flat head screw 220 and the positioning block 221, thereby protecting these components from damage. After the sash is moved to the correct position and locked, if adjustment or release of the sash is needed, the elastic function of the elastic member 222 can help the positioning block 221 reset within the positioning groove 211c, ensuring a smooth unlocking process. The presence of the elastic member 222 makes the unlocking process smoother, as it can provide some elastic force to help the positioning block 221 more easily disengage from the U-shaped groove during unlocking, reducing the difficulty of operation. The elastic member 222 includes but is not limited to springs, rubber washers, polyester or polyimide diaphragms, elastic plastic parts, and other products. In actual application, the choice of which elastic member depends on the specific requirements of the side shift locking structure, including the required elastic force, durability, working temperature range, cost, and installation space. These factors need to be considered in the design to ensure that the elastic member can effectively complete its function in the side shift locking structure.

[0047] In some embodiments, the cover plate 110 has a through hole 111, and the bottom of the positioning seat 210 has a through shaft 212 extending into the through hole 111. The design of the through hole 111 and the through shaft 212 provides a mechanical connection method, allowing the positioning seat 210 to be stably fixed on the cover plate 110. This connection method helps improve the stability of the entire side shift locking structure, ensuring that the positioning seat 210 does not displace during the sash side shift process. When assembling the positioning seat 210, first place the positioning seat 210 on the cover plate 110, then insert the through shaft 212 through the through hole 111, with one end of the through shaft 212 fixed to the bottom of the positioning seat 210 and the other end passing through the through hole 111 and fixed to the cover plate 110. In this way, the positioning seat 210 is firmly positioned on the cover plate 110

[0048] In some embodiments, the top of the cover plate 110 has a first toothed structure 112, and the bottom of the positioning seat 210 has a second toothed structure 213, with the first toothed structure 112 and the second toothed structure 213 intermeshing. Through the intermeshing of the toothed structures, a stronger fixing force than ordinary flat contact can be provided, ensuring a tight connection between the cover plate and the positioning seat. This design helps maintain the stability of the structure during the sash side shift process, preventing relative displacement due to vibration or external force. The design of the toothed structure simplifies the assembly process, as they can automatically align and lock, reducing the adjustment work during assembly. This design improves assembly efficiency and reduces production costs. When the cover plate 110 and the positioning seat 210 are close to each other, the toothed structures will automatically intermesh, achieving precise alignment and locking.

[0049] In some embodiments, the cover plate 110 has mounting holes 113 on both sides, the carrier 100 has mounting blocks 102 on both sides inside, and the positioning seat 210 has screw holes 214 on both sides. First screws 215 are installed through the mounting holes 113 and screwed into the mounting blocks 102. The first screws 215 are installed through the mounting holes 113 and screwed into the mounting blocks 102, so that the positioning seat 210 is firmly fixed on the carrier 100 through the cover plate 110. This connection method enhances the stability of the entire side shift locking structure and ensures that the relative position between the cover plate and the carrier remains unchanged. During assembly, first place the cover plate 110 on the carrier 100, ensure that the mounting holes 113 are aligned with the mounting blocks 102, then pass the first screws 215 through the mounting holes 113 of the cover plate and screw them into the mounting blocks 102 through the screw holes 214, and complete the fixation of the cover plate and the carrier.

[0050] In some embodiments, the bottom of the cover plate 110 has balance shafts 114 on both sides, the carrier 100 has balance holes 103 on both sides inside, and the balance shafts 114 fit into the balance holes 103. The precise fit of the balance shafts 114 and the balance holes 103 ensures accurate alignment of the cover plate 110 on the carrier 100, while maintaining the stable position of the cover plate 110 on the carrier 100.

[0051] In some embodiments, the carrier 100 is a groove-shaped member with side shift sliding holes 101 on both sides. The side shift sliding holes 101 allow the side carrier 100 to slide laterally in the pulling component (such as the pulling component mentioned in the background art of application number 2023224682882). This design provides the flexibility required for the side shift of the sash, allowing precise adjustment of the sash as needed. The groove-shaped design of the carrier 100 allows its interior to be used to assemble a pulley assembly for the sliding of the sash in the window frame.

[0052] In some embodiments, the flat head screw 220 has a smooth surface 223 on the outside, and the positioning seat 210 has a second screw 216 threaded on it with its bottom end abutting the smooth surface 223. The smooth surface 223 and the second screw 216 are designed to limit the rotation of the flat head screw 220 on the positioning block 221. This design ensures that the flat head screw does not rotate unnecessarily due to friction with the lock 300 when subjected to side shift force, thereby ensuring the accuracy of the side shift movement. By providing a smooth surface 223 on the outside of the flat head screw and having the second screw 216 abutting the smooth surface at the bottom, a stable contact point is provided, reducing the swing of the screw on the positioning block and improving the operational stability of the entire side shift locking structure.

[0053] In some embodiments, the lock 300 is composed of a first fixed strip 310 and a first lock block 320, wherein the back of the first lock block 320 is fixed to the front of the first fixed strip 310; the first fixed strip 310 has first screw holes 311 on both sides; the first lock block 320 has a first U-shaped groove 321 on the top, which is open to the outside, wherein the side of the first U-shaped groove 321 close to the first fixed strip 310 is recessed inward, and the flat end of the flat head screw 220 is adapted in the first U-shaped groove 321.

[0054] The design of the screw holes 311 on both sides of the first fixed strip 310 and the first U-shaped groove 321 on the first lock block 320 simplifies the assembly process. By means of the screw holes, the first lock block can be conveniently fixed on the jamb of the window sash or the window frame. The first U-shaped groove 321 provides a fitting space for the flat head screw. The design of the U-shaped groove 321 allows the flat end of the flat head screw 220 to be adapted in the groove, achieving the locking of the window sash after lateral displacement. This design ensures that the window sash can be stably maintained at the set position after sliding, improving the reliability of the entire system.

[0055] In some embodiments, the lock 300 is composed of a second fixed strip 330, a buckle plate 340 and a second lock block 350, wherein the buckle plate 340 is located between the second fixed strip 330 and the second lock block 350.

[0056] The buckle plate 340 has multiple insertion holes 342 on both sides, and the second fixed strip 330 has multiple insertion blocks 332 on both sides, which are adapted in the insertion holes 342, and the insertion blocks 332 are provided with second screw holes 333; the back of the buckle plate 340 is provided with a buckling groove 341, and the front of the second fixed strip 330 is provided with a buckling frame 331, which is adapted in the buckling groove 341; the second lock block 350 is provided with a second U-shaped groove 351, and the second lock block 350 is provided with a U-shaped stop edge 352 corresponding to the second U-shaped groove 351, wherein the flat end of the flat head screw 220 is adapted in the second U-shaped groove 351 behind the U-shaped stop edge 352. The front of the buckle plate 340 is also provided with a decorative plate 343.

[0057] The lock structure is modularly designed, so that each component can be independently assembled and adjusted, improving the flexibility and convenience of assembly. The combination of the buckle plate 340, the second fixed strip 330 and the second lock block 350 provides a compact and easy-to-install side shift locking system. The cooperation of the insertion hole 342 on the buckle plate 340 with the insertion block 332 on the second fixed strip 330, and the cooperation of the buckle groove 341 on the back of the buckle plate with the buckle frame 331 on the front of the second fixed strip, ensure the accurate positioning of the lock structure. This accurate positioning helps to achieve accurate locking after the sash is shifted sideways. The installation of the decorative plate 343 on the front of the buckle plate 340 not only enhances the aesthetics of the lock structure, but also provides additional protection against direct contact between the buckle plate and the fixed strip, reducing wear and tear.

[0058] During the sliding of the sash, the flat end of the flat head screw moves to the position of the second U-shaped groove 351 on the second lock block 350. After sliding into position, the flat end of the flat head screw 220 fits into the second U-shaped groove 351 and is locked by the U-shaped stop 352. This design ensures that the sash can be stably maintained at the set position after sliding.

[0059] In some embodiments, the lock 300 includes a third lock block 360 having a third U-shaped groove 361 open to the outside, wherein the back of the third U-shaped groove 361 is recessed inward, and the flat end of the flat head screw 220 fits into the third U-shaped groove 361. The third lock block 360 has a plurality of third screw holes 362 arranged obliquely.

[0060] The third U-shaped groove 361 on the third lock block 360 is designed to be recessed inward, which helps to enhance the locking force. When the flat end of the flat head screw 220 fits into the U-shaped groove, the force is more concentrated, thereby improving the stability of the locking. The oblique arrangement of the third screw hole 362 helps to disperse the side shift force and reduce direct shear force, which can improve the durability and impact resistance of the lock structure and prolong its service life.

[0061] When the sash is sliding, the flat end of the flat head screw moves to the position of the third lock block 360. After sliding into position, the flat end of the flat head screw 220 fits into the third U-shaped groove 361.

[0062] In addition, the side shift locking structure in this application can be used in the sliding door and window gap compensation assembly with application number 2023224682882, the hidden cutting type locking middle column and door and window locking mechanism with application number 2023230255080, the flat door and window guide wheel assembly with application number 2024201137693, the novel flat door and window guide wheel assembly with application number 2024201225923, or the door and window corner device and door and window side shift structure.

[0063] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
