[0002] In window sash structures, the engagement of the lock seat and locking points is a key component for enabling the window to open, close, and lock. The lock seat is typically installed on the window sash profile and interlocks with the locking points on the window frame to ensure the window's stability and seal when closed. Traditional lock seat structures are usually made of metal and fixed to the C-groove of the window sash with screws. However, existing lock seat installation methods have certain limitations, resulting in low installation efficiency, complex operation, and negatively impacting the overall assembly experience.

[0003] Currently, common lock seat installation methods typically require initially positioning the lock seat within the C-groove of the window sash, followed by tightening with screws. Due to the high precision required for the fit between the lock seat and the profile groove, the lock seat's position often needs to be adjusted multiple times during installation to ensure accurate alignment with the locking point. Furthermore, during screw tightening, installers usually need to hold the lock seat with one hand while operating the screwdriver with the other; otherwise, the lock seat is prone to shifting or falling off, increasing installation difficulty and increasing the risk of misalignment due to operational errors, thus affecting the normal use of the window.

[0030] like Figures 1 to 4 As shown, this utility model discloses a quick-install lock seat structure, which is installed in the profile groove 100 of the window sash and cooperates with the locking points on the window frame to realize the opening, closing and locking functions of the window. The quick-install lock seat structure includes a lock block 10, a lock block pad 40 and a fastener 70. The lock block 10 has an inner end 10a and an outer end 10b arranged opposite to each other. The inner end 10a faces the profile groove 100 and is provided with a snap-fit ​​component 20. The lock block 10 also has an inclined first oblique hole 30. The lock block pad 40 is fixed to the inner end 10a of the lock block 10. The top of the lock block pad 40 is provided with an elastic barb arm 50. The end of the elastic barb arm 50 facing the profile groove 100 is provided with a guide slope 51. The lock block pad 40 has an inclined second oblique hole 60. The first oblique hole 30 and the second oblique hole 60 are coaxially arranged and interconnected. The profile slot 100 is a European standard C-type slot; the elastic barb arm 50 and the snap-fit ​​component 20 are respectively disposed on opposite sides of the locking block pad 40 and the locking block 10, and cooperate with the corresponding sidewall of the profile slot 100; in addition, the locking block 10 is made of metal, and the locking block pad 40 is made of plastic; understandably, the elastic barb arm 50 of the locking block pad 40 has elastic deformation capability. The fastener 70 passes through the first inclined hole 30 and the second inclined hole 60.

[0031] like Figure 5As shown, during installation, the latching member 20 of the locking block 10 extends obliquely into and engages with the lower side wall of the profile slot 100; a thrust in direction A is applied to the quick-release lock seat structure, and the guide slope 51 contacts the edge of the profile slot 100, causing the elastic barb arm 50 to be compressed. The elastic deformation of the elastic barb arm 50 allows the entire quick-release lock seat to smoothly enter the profile slot 100. Figure 6 As shown, after entering the profile groove 100, the elastic barb arm 50 and the snap-fit ​​component 20 abut against the side wall of the profile groove 100, providing support and positioning. Figure 7 As shown, the fastener 70 is locked in, and the process does not require manual fixing, making installation convenient; at the same time, it does not require multiple disassembly and reassembly of the fastener 70 to adjust its position, improving installation efficiency.

[0032] Please see Figures 1 to 4 The inner end 10a of the locking block 10 has a horizontally extending platform portion 11. The locking block pad 40 is fixed to the top of the platform portion 11, and the lower surface of the locking block pad 40 is in contact with the upper surface of the platform portion 11. The platform portion 11 provides support for the locking block pad 40, improving the overall structural stability. Specifically, in order to achieve the structural connection between the locking block 10 and the locking block pad 40, the inner end 10a of the locking block 10 has a horizontally extending connecting protrusion 12 and a connecting post 13. In addition, in order to ensure the stability of the connection under force, in this embodiment, there are two connecting posts. The connecting protrusion 12 is located in the middle of the inner end 10a of the locking block 10, and the two connecting posts 13 are symmetrically arranged on both sides of the connecting protrusion 12. At the same time, the outer wall of the connecting post 13 has a plurality of anti-slip grooves 131 extending axially, and the plurality of anti-slip grooves 131 are evenly distributed along the circumference of the connecting post 13. The inner end 10a of the locking block 10 also has a limiting groove 14.

[0033] Specifically, the outer end 10b of the locking block 10 is provided with a locking part 15. In this embodiment, the cross-sectional shape of the locking part 15 is trapezoidal, and the shape of the locking point is correspondingly set. Through the matching shape structure, the two are locked together, thereby realizing the window opening and closing and locking functions.

[0034] Please see Figure 2 The snap-fit ​​component 20 includes a snap-fit ​​protrusion 21 extending vertically downward from the bottom of the platform portion 11 and a reinforcing rib 22 integrally formed on the side of the snap-fit ​​protrusion 21. The top of the reinforcing rib 22 is connected to the bottom surface of the platform portion 11. The snap-fit ​​protrusion 21 is used to snap with the lower side wall of the profile groove 100. The reinforcing rib 22 provides support for the snap-fit ​​protrusion 21 and strengthens the structural strength of the snap-fit ​​protrusion 21.

[0035] Please see Figure 3 and Figure 4The locking block pad 40 has a clearance groove 41 in the middle and a connecting hole 42 on it. The clearance groove 41 corresponds to the connecting protrusion 12, and the connecting hole 42 corresponds to the connecting post 13. When assembling the locking block 10 and the locking block pad 40, the connecting protrusion 12 is assembled in the clearance groove 41, and the inner sidewall of the clearance groove 41 and the sidewall of the connecting protrusion 12 form an interference fit. The connecting post 13 is inserted into the connecting hole 42, and the outer wall of the connecting post 13 and the inner wall of the connecting hole 42 form an interference fit. Through the interference fits between the connecting protrusion 12 and the clearance groove 41, and between the connecting post 13 and the connecting hole 42, the overall connection between the locking block 10 and the locking block pad 40 is initially achieved, preventing the locking block 10 and the locking block pad 40 from separating during the installation of the quick-install lock seat structure into the profile slot 100, improving the overall structural strength and stability, and ensuring the function of hands-free installation of the fastener 70. It should be noted that in this embodiment, two connecting holes 42 and two connecting posts 13 are provided. The symmetrical arrangement on both sides ensures the connection strength between the locking block 10 and the locking block pad 40. However, the number of connecting holes 42 and two connecting posts 13 is not limited to two and can be adjusted according to actual product requirements.

[0036] Specifically, the locking pad 40 extends a limiting arm 43 on the side facing the locking block 10; when the locking block 10 and the locking pad 40 are assembled and connected, the limiting arm 43 extends into the limiting groove 14 to limit each other and prevent relative shaking, which would affect the structural stability.

[0037] Please see Figures 1 to 4 The first oblique hole 30 obliquely penetrates the protrusion 12, and in this embodiment, the first oblique hole 30 and the second oblique hole 60 are threaded holes; wherein, the angle between the axis of the first oblique hole 30 and the second oblique hole 60 and the horizontal line is 65-75°, ensuring that the fastener 70 can be smoothly inserted obliquely into the first oblique hole 30 and the second oblique hole 60. Correspondingly, in this embodiment, the fastener 70 is a screw. Figure 7 As shown, after the locking block 10 and the locking block pad 40 are inserted into the profile groove 100, the fastener 70 is screwed into the first inclined hole 30 and the second inclined hole 60. Finally, one end of the fastener 70 extends into the profile groove 100 and abuts against the top of the inner side of the profile groove 100, thereby locking the locking block 10, the locking block pad 40 and the profile groove 100.

[0038] Compared to existing technologies, the quick-install lock seat structure of this utility model achieves convenient installation and reliable fixation through the rigid engagement of the snap-fit ​​component 20 at the bottom of the lock block 10 and the elastic deformation engagement of the elastic barb arm 50 at the top of the lock block pad 40. This connection method eliminates the need for manual support during installation; the lock seat can be initially positioned by simply aligning it with the profile groove 100 and pushing it in. Final fixation is then achieved through the obliquely positioned fasteners 70, significantly reducing installation difficulty and operational intensity. The interference fit between the connecting protrusion 12 at the inner end 10a of the lock block 10 and the clearance groove 41 of the lock block pad 40 ensures tight contact at the core connection points. Simultaneously, the interference fit between the symmetrically positioned connecting posts 13 and the connecting holes 42 further enhances the overall structural stability. Furthermore, the fasteners 70 securely lock the lock block 10, lock block pad 40, and profile groove 100 through obliquely positioned holes, ensuring the structural reliability of the window sash hardware structure.

[0039] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
