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

[0041] Embodiment 1

[0042] The present utility model will be further described in detail below with reference to the drawings.

[0043] Please refer to Figures 1 to 5 , this 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 towards the first side wall 11 to form a clamping groove 14 for connecting a door panel 4. A relief 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 housing 21, a lock tongue 22 and a handle base 23. The lock core housing 21 is inserted through the clamping groove 14, and the first end of the lock core housing 21 is fixed to the lock tongue hole 111. The lock tongue 22 is movably arranged in the lock core housing 21 and can extend and retract 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 lock box fixed on the door frame of the door opening to lock the door, and when the lock tongue 22 retracts into the lock tongue hole 111, it is separated from the lock groove of the lock box to unlock; the first end of the handle base 23 is inserted into the clamping groove 14 from the relief opening 143, and the handle base 23 covers the lock core housing 21.

[0044] In addition, this embodiment also provides a door and window system, which includes the above lock installation structure and also includes a door panel 4. The first side of the door panel 4 is clamped in the clamping groove 14. An installation opening for accommodating the lock core housing 21 is provided on the first side of the door panel 4. There are two handle bases 23, and the two handle bases 23 are respectively located on both sides of the door panel 4 in the thickness direction to fully cover the lock core housing 21. Specifically, the two handle bases 23 are both abutted against both sides of the door panel 4.

[0045] An installation structure of a lock provided in this embodiment designs the first end of the handle base 23 to be inserted into the clamping groove 14 of the frame 1 through the relief opening 143, rather than directly abutting against the second side wall 12. On the one hand, since the clamping groove 14 usually has a relatively unified standard in the design of the frame 1, the handle base 23 only needs to adapt to the unified standard to be widely applicable. Even when the thickness or shape of the second side wall 12 changes, as long as the clamping groove 14 maintains relatively consistent dimensions and positions, the handle base 23 can still be effectively installed. The handle base 23 does not need to be repeatedly designed to adapt to different design styles of the second side wall 12, thereby greatly improving the production standardization degree 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 inserting the handle base 23 into the clamping groove 14 makes its combination with the frame 1 closer, reducing the gaps that may be generated due to directly abutting against the second side wall 12, thereby enhancing the aesthetic 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, reducing looseness or displacement caused by external forces and extending the service life of the lock 2.

[0046] As Figure 1 and Figure 4 shown, preferably, in this embodiment, the side of the clamping groove 14 away from the first side wall 11 has two oppositely arranged groove top walls 144, and the two groove top walls 144 are used to clamp both sides of the door panel 4 in the thickness direction, and the relief opening 143 is opened between the two groove top walls 144. In this way, the two groove top walls 144 are used to clamp both sides of the door panel 4 in the thickness direction, and this clamping method can effectively fix the door panel 4, preventing it from displacing or shaking during use, thereby improving the overall stability and safety of the door and window system. At the same time, the relief opening 143 is opened between the two groove top walls 144. This design not only meets the requirement for the first end of the handle base 23 to be 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 base 23 can smoothly enter the clamping groove 14 from the relief opening 143 and cooperate with the groove top walls 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 direction of the distance between the two groove top walls 144 is defined as the first direction. More specifically, the first direction is the same as the thickness direction of the door panel, and the first direction can refer to Figure 2 the e1 direction in Figure 1 and Figure 4As shown, the top wall 144 of the groove has a side edge that extends beyond the side edge of the relief opening 143 in the first direction, and the side edge abuts against the side of the handle base 23 away from the lock core housing 21. In this way, on the one hand, the side edge of the top wall 144 of the groove provides an additional supporting effect on 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 receives additional support from the side edge of the top wall 144 of the groove. This double-support structure significantly improves the stability of the handle base 23 and reduces the risk of shaking or deformation during use due to external forces. On the other hand, the abutting relationship between the side edge of the top wall 144 and the handle base 23 also enhances the overall sealing performance of the lock installation structure. Since the side edge closely abuts against the handle base 23, an effective sealing barrier is formed between them, which can prevent external impurities such as dust and moisture from entering 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 top wall 144 and the handle base 23 makes the entire lock installation structure look neater and more unified, enhancing the overall visual effect of the door and window system.

[0048] As Figure 2 , Figure 3 and Figure 4 shown, preferably, in this embodiment, the clamping groove 14 has a bottom wall 141 that is disposed opposite to the top wall 144 of the groove. The bottom wall 141 is located between the first side wall 11 and the top wall 144 of the groove, and the bottom wall 141 is also opposite to the first side wall 11. The bottom wall 141 is provided with a limiting hole 142, and the bottom wall 141 has a limiting surface 1411. The lock core housing 21 is inserted through the limiting hole 142, and the first end of the handle base 23 abuts against the limiting surface 1411. In this way, on the one hand, the insertion position of the lock core housing 21 can be accurately guided through the limiting hole 142 on the bottom wall 141, ensuring the accuracy and reliability of the installation of the lock core housing 21. On the other hand, the distance between the first side wall 11 and the bottom wall 141 only needs to meet the requirements of fixing the first end of the lock core housing 21 in the lock tongue hole 111 and abutting the first end of the handle base 23 against the limiting surface 1411, so as to achieve the precise positioning and fixing 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 base 23 and the frame 1 through physical contact, effectively preventing the handle base 23 from shaking or shifting during use due to external forces, thereby improving the stability and durability of the entire lock installation structure.

[0049] As 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; 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 this 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 can be understood 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 circumferential side wall of the first end of the lock core housing 21, and the limiting flange 211 abuts against the side of the first side wall 11 away from the handle base 23. In this way, on the one hand, the existence of the limiting flange 211 ensures the stable installation of the lock core housing 21 in the lock tongue hole 111. When installing the lock core housing 21, the limiting flange 211 will naturally abut against the side of the first side wall 11 away from the handle base 23, forming a firm limiting structure. The interval between the first side wall 11 and the bottom wall 141 of the groove only needs to meet the requirements that the limiting flange 211 abuts against the first side wall 11 and the first end of the handle base 23 abuts against the limiting surface 1411, so as to realize the precise positioning and fixation of the lock 2 on the frame 1. Moreover, this limiting structure can not only effectively prevent the lock core housing 21 from loosening or falling off due to external forces during use, but also ensure the close fit between the lock core housing 21 and the frame 1, improving the sealing performance 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 housing 21, the installer can judge whether the lock core housing 21 is correctly installed in place by observing the relative position between 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 housing 21 has been correctly installed and no additional adjustment or calibration is required.

[0052] It can be understood that the handle 24 needs to rotate during use. After long-term use or improper operation, the handle base 23 may be displaced relative to the lock core housing 21 under the action of the handle 24. That is to say, there may be a certain deviation between the actual relative position and the preset relative position of the handle base 23 and the lock core, which will cause the problem that the movement of the handle 24 and the lock tongue 22 is not smooth enough.

[0053] As Figure 1 and Figure 5 As shown, to solve the above problems, further, in this embodiment, the lock installation structure further includes a fixing structure 3, and the fixing structure 3 is arranged between the lock core housing 21 and the handle base 23 to fix the relative positions of the lock core housing 21 and the handle base 23. In this way, by arranging the fixing structure 3 between the lock core housing 21 and the handle base 23, the problem that the handle base 23 is displaced relative to the lock core housing 21 due to long-term use or improper operation is effectively avoided, so as to ensure that the relative position between the handle base 23 and the lock core housing 21 always remains in the preset optimal state. Furthermore, the handle 24 and the lock tongue 22 can move smoothly during movement, and there will be no jamming or increased resistance caused by position deviation, 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 seat 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 disposed on the lock core housing 21. The connecting block 31 is provided with a second fixing hole 311. The first fastener 32 connects the first fixing hole 233 and the second fixing hole 311. In this way, the first fastener 32 (such as a screw, a bolt, etc.) passes through the first fixing hole 233 and the second fixing hole 311, firmly fixing the handle seat 23 on the lock core housing 21. The installer only needs to align the first fixing hole 233 with the second fixing hole 311 to ensure that the handle seat 23 and the lock core housing 21 can be accurately positioned during assembly, effectively preventing position deviation under long-term use or external force. Moreover, the installation process is simplified, without complex adjustment or positioning steps, improving the installation efficiency. In addition, when maintenance or replacement of the components of the lock 2 is required, only by loosening the first fastener 32, the handle seat 23 and the lock core housing 21 can be easily separated, facilitating inspection, cleaning or replacement of the internal components, improving the maintainability of the lock 2 and reducing the maintenance cost.

[0055] As Figure 5 shown, preferably, in this embodiment, the lock core housing 21 is provided with a slot 212. The connecting block 31 is snap-fitted into the slot 212. The snap-fitting design of the slot 212 and the connecting block 31 simplifies the installation process. When installing the connecting block 31, only by aligning the connecting block 31 with the slot 212 and gently pushing it in, the fixing can be completed. Compared with traditional fastening methods (such as using screws or bolts), the number of components is reduced, and no additional tools or complex operation steps are required, greatly improving the installation efficiency.

[0056] It should be noted that in some other embodiments, the connecting block 31 can also but is not limited to be connected to the lock core housing 21 by screwing, pinning, welding or integral molding. It can be selected according to actual needs and is not uniquely limited here.

[0057] As Figure 1 and Figure 5 shown, preferably, in this embodiment, the fixing structure 3 further includes a decorative cover 33. The decorative cover 33 is embedded in the first fixing hole 233 to block the first fastener 32. In this way, the decorative cover 33 is embedded in the first fixing hole 233, effectively blocking the exposed part of the first fastener 32. On the one hand, it can make the appearance of the lock body structure more tidy and unified, 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, etc., which helps to extend the service life of the first fastener 32, thus ensuring the stability and reliability of the lock body structure.

[0058] As Figure 1 and Figure 5As shown, specifically, in this embodiment, the first end of the handle seat 23 (i.e., the first housing 231) is close to the locking tongue hole 111, and the second end of the handle seat 23 is far from the locking tongue hole 111. The first end of the lock core housing 21 is fixed to the locking tongue hole 111, and the second end of the lock core housing 21 is far from the locking tongue 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 core housing 21. Specifically, in this embodiment, the first fixing hole 233 is provided at the tail of the second housing 232. With such a setting, on the one hand, this layout helps to optimize the force-bearing situation of the lock 2. Since the main force generated during the operation of the handle 24 is the rotational force, and this layout makes the fixing position of the first fastener 32 outside the moment 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 locking tongue 22 performs locking or unlocking operations by extending or retracting relative to the locking tongue hole 111. Setting the fixing structure 3 at a position far from the locking tongue hole 111 can prevent the first fastener 32 or the connecting block 31 from interfering with the movement track of the locking tongue 22, reducing the wear and noise generated by friction, and helping to maintain the smooth operation of the lock 2 and extend its service life. On the other hand, since both the first fastener 32 and the connecting block 31 are far from the locking tongue hole 111, the installer can more easily access and operate the first fastener 32 without worrying about conflicts with the locking tongue 22 or other internal components, which is more convenient and fast during installation and maintenance.

[0059] As Figure 3 and Figure 4 shown, specifically, in this embodiment, the frame 1 further includes two third side walls 13, and 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 Two

[0061] The main difference between this embodiment and the first embodiment is that the specific design specifications of the frame 1 are different; specifically, please refer to Figures 6 to 9 , in this 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 collinear, the two first sub-side walls 121 are both 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 in a one-to-one correspondence, the two second sub-side walls 122 both extend in a direction away from the first side wall 11, and the clamping groove 14 is formed between the two second sub-side walls 122.

[0062] Embodiment Three

[0064] Embodiment 4

[0065] The main difference between this embodiment and the first, second and third embodiments is that the specific design specifications of the frame 1 are different; please refer to the Figures 14 to 17 In this embodiment, the second side wall 12 has two second sub-side walls 122, the two second sub-side walls 122 are arranged opposite to each other, the third side wall 13 is vertically connected to the first side wall 11, one end of the second sub-side wall 122 is connected to the third side wall 13, and the other end of the second sub-side wall 122 extends in an arc shape in a direction away from the first side wall 11, and the clamping groove 14 is formed between the two second sub-side walls 122.

[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 improved the production standardization of handle base 23, simplified the design process, shortened the production cycle, and reduced production costs;

[0068] 2) The design of inserting the handle base 23 into the clamping groove 14 through the clearance opening 143 makes it more tightly connected to the frame 1, reducing the gap that may be caused by directly abutting the second side wall 12, thereby improving the aesthetic appearance of the door and window system. It also helps to improve the installation stability of the handle base 23, reduce loosening or displacement caused by external forces, and extend the service life of the lock 2;

[0069] 3) The side edges of the groove top wall 144 provide additional support for the handle base 23. After the handle base 23 is installed, the handle base 23 is supported not only by the internal structure of the clamping groove 14 but also by the side edges of the groove top wall 144. This dual 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 base 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 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 achieve 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.

[0072] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
