[0007] According to some embodiments of the present invention, the side of the clamping groove away from the first side wall has two oppositely arranged groove top walls, the two groove top walls are used to clamp the door panel on both sides in the thickness direction, and the clearance opening is opened between the two groove top walls.

[0008] According to some embodiments of the present invention, the spacing direction between the two groove top walls is defined as a first direction, and the groove top wall has a side edge that exceeds the clearance opening in the first direction, and the side edge is arranged against a side of the handle base away from the lock core shell.

[0009] According to some embodiments of the present invention, the clamping groove has a groove bottom wall arranged opposite to the groove top wall, the groove bottom wall is located between the first side wall and the groove top wall, the groove bottom wall is provided with a limiting hole, the groove bottom wall has a limiting surface, the lock core shell is passed through the limiting hole, and the first end of the handle seat is against the limiting surface.

[0010] According to some embodiments of the present invention, the handle base includes a first shell and a second shell connected to each other; the spacing direction between the two groove top walls is defined as a first direction, the thickness of the first shell in the first direction is less than the thickness of the second shell in the first direction, the first end of the handle base is located in the first shell, and the first shell is inserted into the clamping groove from the yield opening.

[0011] According to some embodiments of the present invention, a limiting flange is provided on the peripheral side wall of the first end of the lock core housing, and the limiting flange is disposed against a side of the first side wall away from the handle seat.

[0012] According to some embodiments of the present invention, the lock installation structure further includes a fixing structure, and the fixing structure is arranged between the lock cylinder housing and the handle seat to fix the relative position of the lock cylinder housing and the handle seat.

[0013] According to some embodiments of the present invention, the handle base is provided with a first fixing hole, the fixing structure includes a connecting block and a first fastener, the connecting block is arranged on the lock core shell, the connecting block is provided with a second fixing hole, and the first fastener is connected to the first fixing hole and the second fixing hole.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0041] Embodiment 1

[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0043] See also Figures 1 to 5 The present embodiment discloses a lock installation structure, which includes a frame 1 and a lock 2; the frame 1 has a first side wall 11 and a second side wall 12 arranged vertically, the first side wall 11 is provided with a lock tongue hole 111, the second side wall 12 is recessed toward the first side wall 11 and is provided with a clamping groove 14, the clamping groove 14 is used to connect the door panel 4, and a clearance opening 143 is also provided on the side of the clamping groove 14 away from the first side wall 11; the lock 2 includes a lock core shell 21, a lock tongue 22 and a handle seat 23, the lock core shell 21 It is penetrated in the clamping groove 14, and the first end of the lock core shell 21 is fixed to the lock tongue hole 111, the lock tongue 22 is movably arranged in the lock core shell 21 and can be extended and retracted relative to the lock tongue hole 111. Specifically, when the lock tongue 22 extends out of the lock tongue hole 111, it can be engaged with the lock groove of the door frame of the lock box fixed to the door opening to lock the door, and when the lock tongue 22 is retracted into the lock tongue hole 111, it is separated from the lock groove of the lock box to unlock the door; the first end of the handle seat 23 is inserted into the clamping groove 14 from the yielding opening 143, and the handle seat 23 covers the lock core shell 21.

[0044] In addition, the present embodiment also provides a door and window system, which includes the lock installation structure as above, and also includes a door panel 4, the first side of the door panel 4 is clamped in the clamping groove 14, the first side of the door panel 4 is provided with an installation opening for accommodating the lock cylinder shell 21, and two handle seats 23 are provided, and the two handle seats 23 are respectively located on both sides of the door panel 4 in the thickness direction to fully cover the lock cylinder shell 21. Specifically, the two handle seats 23 are both against the two sides of the door panel 4.

[0045] In the lock installation structure improved in the present embodiment, the first end of the handle seat 23 is designed to be inserted into the clamping groove 14 of the frame 1 through the clearance opening 143, rather than being directly mounted on the second side wall 12. On the one hand, since the clamping groove 14 usually has a relatively uniform standard in the design of the frame 1, the handle seat 23 only needs to adapt to this uniform standard to achieve wide application. Even if the thickness or shape of the second side wall 12 changes, as long as the clamping groove 14 maintains a relatively consistent size and position, the handle seat 23 can still be effectively installed, and the handle seat 23 does not need to be repeatedly designed. The second side wall 12 is adapted to different design styles, thereby greatly improving the production standardization of the handle base 23, simplifying the design process, shortening the production cycle, and reducing the production cost; on the other hand, the design of the handle base 23 inserted into the clamping groove 14 makes it more tightly combined with the frame 1, reducing the gap that may be generated by directly abutting against the second side wall 12, thereby improving the appearance of the door and window system. At the same time, this close combination also helps to improve the installation stability of the handle base 23, reduce looseness or deviation caused by external force, and extend the service life of the lock 2.

[0046] like Figure 1 and Figure 4 As shown, preferably, in this embodiment, the side of the clamping groove 14 away from the first side wall 11 has two groove top walls 144 arranged opposite to each other, and the two groove top walls 144 are used to clamp the two sides of the door panel 4 in the thickness direction, and the clearance opening 143 is opened between the two groove top walls 144; in this way, the two groove top walls 144 are used to clamp the two sides of the door panel 4 in the thickness direction. This clamping method can effectively fix the door panel 4 to prevent it from displacement or shaking during use, thereby improving the overall stability and safety of the door and window system. At the same time, the clearance opening 143 is opened between the two groove top walls 144. This design not only meets the requirement of the first end of the handle seat 23 being inserted into the clamping groove 14, but also does not sacrifice the clamping function of the clamping groove 14 on the door panel 4. The first end of the handle seat 23 can smoothly enter the clamping groove 14 from the clearance opening 143, and cooperate with the groove top wall 144 to ensure that the door panel 4 is firmly clamped on the frame 1. This design not only simplifies the installation process, but also ensures the stability and reliability of the installation.

[0047] Specifically, preferably, in this embodiment, the spacing direction between the two groove top walls 144 is defined as the first direction. More specifically, the first direction is the same direction as the thickness direction of the door panel. The first direction can be referred to as Figure 2 The e1 direction in Figure 1 and Figure 4As shown, the groove top wall 144 has a side edge that exceeds the clearance opening 143 in the first direction, and the side edge is disposed against a side of the handle seat 23 away from the lock cylinder housing 21 . In this way, on the one hand, the side edge of the groove top wall 144 provides additional support for the handle seat 23. After the handle seat 23 is installed in place, the handle seat 23 is not only supported by the internal structure of the clamping groove 14, but also receives additional support from the side edge of the groove top wall 144. This double support structure significantly improves the stability of the handle seat 23 and reduces the risk of shaking or deformation due to external force during use; on the other hand, the abutment relationship between the side edge of the groove top wall 144 and the handle seat 23 also enhances the overall sealing of the lock installation structure. Since the side edge is tightly against the handle seat 23, an effective sealing barrier is formed between them, which can prevent external impurities such as dust and moisture from entering the interior of the lock 2, thereby protecting the precision components of the lock 2 and extending its service life; in addition, this design also takes into account the aesthetics of the lock 2. The close fit between the side edge of the groove top wall 144 and the handle seat 23 makes the entire lock installation structure look more tidy and unified, thereby improving the overall visual effect of the door and window system.

[0048] like Figure 2 , Figure 3 and Figure 4 As shown, preferably, in this embodiment, the clamping groove 14 has a groove bottom wall 141 arranged opposite to the groove top wall 144, the groove bottom wall 141 is located between the first side wall 11 and the groove top wall 144, the groove bottom wall 141 is also opposite to the first side wall 11, the groove bottom wall 141 is provided with a limiting hole 142, the groove bottom wall 141 has a limiting surface 1411, the lock core shell 21 is penetrated by the limiting hole 142, and the first end of the handle seat 23 is against the limiting surface 1411; in this way, on the one hand, the penetration position of the lock core shell 21 can be accurately guided by the limiting hole 142 on the groove bottom wall 141, ensuring the installation of the lock core shell 21 Accuracy and reliability; on the other hand, the interval between the first side wall 11 and the groove bottom wall 141 only needs to meet the requirements of fixing the first end of the lock cylinder shell 21 on the lock tongue hole 111 and making the first end of the handle seat 23 against the limiting surface 1411, so as to realize the precise positioning and fixation of the lock 2 on the frame 1. This design not only simplifies the installation process of the lock 2, but also enhances the connection strength between the handle seat 23 and the frame 1 through physical contact, effectively preventing the handle seat 23 from shaking or deflecting due to external force during use, thereby improving the stability and durability of the entire lock installation structure.

[0049] like Figure 4As shown, preferably, in this embodiment, the limiting surface 1411 is a limiting plane processed on the groove bottom wall 141, and the specific processing methods include but are not limited to milling or grinding, etc.; it should be noted that, in some other embodiments, the limiting surface 1411 may also be a surface of the groove bottom wall 141 itself that has not undergone additional processing.

[0050] like Figure 2 and Figure 3 As shown, specifically, in the present embodiment, the lock 2 also includes a handle 24; the handle 24 and the lock tongue 22 are transmission connected, and when the handle 24 rotates, the lock tongue 22 can be driven to extend and retract relative to the lock tongue hole 111; preferably, the handle seat 23 includes a first shell 231 and a second shell 232 that are connected to each other; the thickness of the first shell 231 in the first direction is less than the thickness of the second shell 232 in the first direction, the first end of the handle seat 23 is located in the first shell 231, the first shell 231 is inserted into the clamping groove 14 from the yield opening 143, the handle 24 is installed on the second shell 232, and the second shell 232 can be used to install functional components. In this way, on the one hand, the thickness of the first shell 231 is relatively small, so that the first shell 231 can adapt to the size of the clearance opening 143. This design facilitates the first shell 231 to be tightly and firmly inserted into the clamping groove 14 of the frame 1; on the other hand, it is understandable that the installation of the handle 24 and functional components requires more space. In order to facilitate the installation of the handle 24 and functional components, the thickness of the second shell 232 needs to be maintained at a larger size. This design provides sufficient space and support for the installation of the handle 24 and functional components.

[0051] like Figure 3 , Figure 4 and Figure 5As shown, preferably, in this embodiment, a limiting flange 211 is provided on the peripheral side wall of the first end of the lock core housing 21, and the limiting flange 211 is abutted against the side of the first side wall 11 away from the handle seat 23. In this way, on the one hand, the existence of the limiting flange 211 ensures that the lock core housing 21 is firmly installed in the lock tongue hole 111. When the lock core housing 21 is installed, the limiting flange 211 will naturally abut against the side of the first side wall 11 away from the handle seat 23 to form a firm limiting structure. The interval between the first side wall 11 and the groove bottom wall 141 only needs to meet the requirements of making the limiting flange 211 abut against the first side wall 11 and making the first end of the handle seat 23 abut against the limiting surface 1411, so as to realize the precise positioning and fixation of the lock 2 on the frame 1, and this limiting structure can not only effectively It prevents the lock core shell 21 from loosening or falling off due to external force during use, and can also ensure the close fit between the lock core shell 21 and the frame 1, thereby improving the sealing and safety of the entire lock 2; on the other hand, the limiting flange 211 also plays a positioning role. When installing the lock core shell 21, the installer can judge whether the lock core shell 21 has been correctly installed by observing the relative position of the limiting flange 211 and the lock tongue hole 111. Once the limiting flange 211 is completely inserted into the lock tongue hole 111, it means that the lock core shell 21 has been installed correctly and no additional adjustment or correction is required.

[0052] It is understandable that the handle 24 needs to be rotated when used. After long-term use or improper operation, the handle seat 23 may be displaced relative to the lock cylinder shell 21 due to the action of the handle 24. That is to say, there may be a certain deviation between the actual relative position of the handle seat 23 and the lock cylinder and the preset relative position, which will cause the handle 24 and the lock tongue 22 to move less smoothly.

[0053] like Figure 1 and Figure 5 As shown, in order to solve the above problems, further, in this embodiment, the lock installation structure also includes a fixing structure 3, which is arranged between the lock cylinder housing 21 and the handle seat 23 to fix the relative position of the lock cylinder housing 21 and the handle seat 23. In this way, by arranging the fixing structure 3 between the lock cylinder housing 21 and the handle seat 23, the problem of the handle seat 23 being offset relative to the lock cylinder housing 21 due to long-term use or improper operation is effectively avoided, thereby ensuring that the relative position between the handle seat 23 and the lock cylinder housing 21 is always maintained in a preset optimal state, so that the handle 24 and the lock tongue 22 can remain smooth during movement, and there will be no jamming or increased resistance caused by position offset, thereby extending the service life of the lock 2 and improving the overall stability and durability of the lock 2.

[0054] Preferably, in this embodiment, the handle base 23 is provided with a first fixing hole 233, the fixing structure 3 includes a connecting block 31 and a first fastener 32, the connecting block 31 is arranged on the lock core shell 21, the connecting block 31 is provided with a second fixing hole 311, and the first fastener 32 is connected to the first fixing hole 233 and the second fixing hole 311. In this way, the first fastener 32 (such as a screw, bolt, etc.) passes through the first fixing hole 233 and the second fixing hole 311 to firmly fix the handle base 23 on the lock core shell 21. The installer only needs to align the first fixing hole 233 with the second fixing hole 311 to ensure that the handle base 23 and the lock core shell 21 can be accurately aligned during assembly, effectively preventing position displacement due to long-term use or external force. In addition, the installation process is simplified, and no complicated adjustment or positioning steps are required, thereby improving installation efficiency. In addition, when it is necessary to maintain or replace parts of the lock 2, it is only necessary to loosen the first fastener 32 to easily separate the handle base 23 and the lock core shell 21, thereby facilitating the inspection, cleaning or replacement of internal parts, thereby improving the maintainability of the lock 2 and reducing maintenance costs.

[0055] like Figure 5 As shown, preferably, in this embodiment, the lock core housing 21 is provided with a card slot 212, and the connecting block 31 is card-engaged in the card slot 212. The card connection design of the card slot 212 and the connecting block 31 simplifies the installation process. When installing the connecting block 31, it is only necessary to align the connecting block 31 with the card slot 212 and gently push it in to complete the fixation. Compared with traditional fastening methods (such as using screws or bolts), the number of parts is reduced, and no additional tools or complicated operating steps are required, thereby greatly improving the installation efficiency.

[0056] It should be noted that, in some other embodiments, the connecting block 31 may also be connected to the lock cylinder housing 21 by means of, but not limited to, screw connection, pin connection, welding, or integral molding. This can be selected according to actual needs and is not limited here.

[0057] like Figure 1 and Figure 5 As shown, preferably, in this embodiment, the fixing structure 3 further includes a decorative cover 33, which is embedded in the first fixing hole 233 to cover the first fastener 32. In this way, the decorative cover 33 is embedded in the first fixing hole 233, effectively covering the exposed part of the first fastener 32. On the one hand, the appearance of the lock body structure can be made neater and more uniform, achieving a better visual effect; on the other hand, the decorative cover 33 can also protect the first fastener 32 from the influence of the external environment, such as moisture, corrosion or physical collision, which helps to extend the service life of the first fastener 32, thereby ensuring the stability and reliability of the lock body structure.

[0058] like Figure 1 and Figure 5As shown, specifically, in this embodiment, the first end of the handle seat 23 (that is, the first shell 231) is close to the lock bolt hole 111, the second end of the handle seat 23 is far away from the lock bolt hole 111, the first end of the lock cylinder shell 21 is fixed to the lock bolt hole 111, and the second end of the lock cylinder shell 21 is far away from the lock bolt hole 111. Preferably, the first fixing hole 233 is provided at the second end of the handle seat 23, and the connecting block 31 is provided at the second end of the lock cylinder shell 21. Specifically, in this embodiment, the first fixing hole 233 is provided at the tail of the second shell 232. Such arrangement, on the one hand, helps to optimize the stress condition of the lock 2, because the handle 24 mainly generates a rotational force during operation, and this arrangement makes the fixed position of the first fastener 32 outside the torque center of the rotational force, thereby reducing the shear force and torsional force borne by the first fastener 32, which is beneficial to maintaining its stability and extending its service life; on the other hand, the lock tongue 22 locks or unlocks by extending relative to the lock tongue hole 111, and setting the fixing structure 3 at a position away from the lock tongue hole 111 can avoid interference between the first fastener 32 or the connecting block 31 and the movement trajectory of the lock tongue 22, reduce wear and noise caused by friction, and help maintain the smooth operation of the lock 2 and extend its service life; on the other hand, because the first fastener 32 and the connecting block 31 are both away from the lock tongue hole 111, the installer can more easily approach and operate the first fastener 32 without worrying about conflict with the lock tongue 22 or other internal components, which is more convenient and quick during installation and maintenance.

[0059] like Figure 3 and Figure 4 As shown, specifically, in this embodiment, the frame 1 further includes two third side walls 13, the two third side walls 13 are connected between the first side wall 11 and the second side wall 12, and the first side wall 11 and the second side wall 12 are arranged parallel to each other.

[0060] Embodiment 2

[0061] The main difference between this embodiment and the first embodiment is that the specific design specifications of the frame 1 are different; please refer to Figures 6 to 9 In the present embodiment, the second side wall 12 has two first sub-side walls 121 and two second sub-side walls 122. The two first sub-side walls 121 are collinearly arranged, and the two first sub-side walls 121 are parallel to the first side wall 11. The third side wall 13 is connected between the first side wall 11 and the first sub-side wall 121. The two second sub-side walls 122 are vertically connected to the two first sub-side walls 121 one by one.

[0066] In summary, the lock installation structure and the door and window system including the lock installation structure disclosed in the present invention can at least bring the following beneficial technical effects:

[0067] 1) Greatly improve the production standardization of the handle seat 23, simplify the design process, shorten the production cycle, and reduce the production cost;

[0068] 2) The handle base 23 is inserted into the clamping groove 14 through the clearance opening 143, so that it is more tightly combined with the frame 1, reducing the gap that may be generated by directly abutting against the second side wall 12, thereby improving the aesthetics of the door and window system, and also helping to improve the installation stability of the handle base 23, reduce looseness or deviation caused by external force, and extend the service life of the lock 2;

[0069] 3) The side edge of the groove top wall 144 provides additional support for the handle base 23. After the handle base 23 is installed in place, the handle base 23 is not only supported by the internal structure of the clamping groove 14, but also by the side edge of the groove top wall 144. This double support structure significantly improves the stability of the handle base 23.

[0070] 4) The close fit between the side edge of the groove top wall 144 and the handle seat 23 makes the entire lock installation structure look neater and more unified, improving the overall visual effect of the door and window system

[0071] 5) The spacing between the first side wall 11 and the groove bottom wall 141 only needs to satisfy the requirements that the limiting flange 211 abuts against the first side wall 11 and the first end of the handle seat 23 abuts against the limiting surface 1411, so that the lock 2 can be accurately positioned and fixed on the frame 1. This design not only simplifies the installation process of the lock 2, but also enhances the connection strength between the handle seat 23 and the frame 1 through physical contact.

[0072] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
