Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically to an adaptive lock cover structure for a swing door lock. Background Technology

[0002] Currently, most bathroom doors and sliding doors use a combination of frame and glass. Hinged door locks are installed on the glass. Existing hinged door lock structures typically include an inner handle, an outer handle, and a lock cylinder. The inner and outer handles are installed opposite each other on the door panel, and the lock cylinder is installed between them. The lock bolt can extend or retract from the bolt hole in the door frame. To enhance the overall aesthetics, the handle bases of the inner and outer handles rest against the door frame. However, due to different requirements from manufacturers and consumers, there are various design specifications for the frame. Therefore, the length and shape of the handle base need to be repeatedly designed to fit different frame types, making modular production of the handle base difficult. This leads to the patent application number 202421595779.1. The utility model document discloses a door handle installation structure based on a unified door frame material, including a profile with a convex cross-section. The convex surface of the profile has a door panel mounting groove, and the profile has a connected latch groove, a first slot, and a second slot. The latch groove is located between the first slot and the second slot. The handle assembly includes a first panel, a second panel, an inner door handle, an outer door handle, and a lock cylinder. The inner door handle is installed on the first panel, the outer door handle is installed on the second panel, and the lock cylinder is installed between the first panel and the second panel. The same end of the first panel and the second panel are respectively inserted into the first slot and the second slot, and the latch of the lock cylinder faces the latch groove.

[0003] The aforementioned patent achieves a unified installation by creating a latch groove, a first slot, and a second slot on the profile. This is because, when installing the handle assembly, the first panel (i.e., the handle base) and the second panel (i.e., the handle base) can be inserted into the first and second slots respectively. However, when installing a door lock, two slots in addition to the latch groove need to be created on the profile. The depth and position tolerances of these two slots are critical. If the machining precision is insufficient, the first and second panels may not install smoothly, and in severe cases, the latch may not align accurately. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an adaptive lock cover structure for a swing door lock, which addresses the shortcomings of the prior art and improves assembly efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adaptive lock cover structure for a swing door lock, comprising an inner handle and an outer handle connected to each other, a lock cover disposed on the inner and outer handles, and a lock body disposed between the two lock covers. The two lock covers are respectively provided with corresponding mounting studs and mounting screws. The mounting studs include a first mounting stud close to the lock tongue groove of the profile and a second mounting stud away from the lock tongue groove of the profile. The mounting screws include a first mounting screw that extends into the lock body and is threadedly connected to the first mounting stud, and a second mounting screw that is threadedly connected directly to the second mounting stud. The second mounting stud abuts against the outer peripheral surface of the lock body. The lock cover can slide relative to the lock body. Both the second mounting screw and the second mounting stud are fitted with elastic elements that abut the lock cover against the profile.

[0006] The present invention, which has the above-mentioned features, has the following characteristics: the lock cover directly abuts against the profile through an elastic element, eliminating the need to open slots other than the lock tongue groove on the profile, reducing the difficulty of profile processing and facilitating assembly; when there are differences in profile specifications, the lock cover can slide to adapt to the profile, and the pre-tightening force of the elastic element ensures that the lock cover and the profile fit tightly, realizing the self-adaptive installation of the lock cover; the first mounting stud is located in the lock body to ensure that the lock body and the lock tongue groove maintain precise alignment during self-adaptive adjustment.

[0007] A further feature of this invention is that the elastic element includes a mounting portion mounted on a second mounting screw or a second mounting stud, and at least one pin extending from the mounting portion. A limiting rib is provided on at least one inner wall of the lock cover parallel to the ground, which abuts against the pin. The pin abuts against the side of the limiting rib away from the first mounting screw.

[0008] The present invention, which has the above-mentioned features, forms a continuous preload by keeping the pin of the elastic element against the side of the limiting rib away from the profile, thereby ensuring that the lock cover is always against the profile after installation and preventing the lock cover from loosening.

[0009] A further feature of this invention is that the number of pins is two, and limiting ribs that abut against the pins are provided on the inner walls of both sides of the lock cover.

[0010] The present invention, which has the above-mentioned features, achieves uniform force by setting two symmetrical pins, thus avoiding the lock cover from shifting due to uneven force.

[0011] A further feature of this invention is that the mounting part is a U-shaped ring that engages with a second mounting screw or a second mounting stud.

[0012] The present invention having the above-mentioned features is an embodiment of the mounting part, which can be easily installed by simply snapping the mounting part onto the outer circumferential surface of the second mounting screw or the second mounting stud.

[0013] A further feature of this invention is that the mounting portion is an open ring fitted around the outer periphery of the second mounting screw or the second mounting stud.

[0014] The present invention having the above features is another embodiment of the mounting part, which can be easily installed by simply fitting the mounting part onto the outer circumferential surface of the second mounting screw or the second mounting stud.

[0015] A further feature of this invention is that the lock cover is symmetrically provided with two U-shaped grooves for the installation studs and the installation screws to pass through, and the lock body is provided with a first waist-shaped groove for the first installation screw and the first installation stud to pass through.

[0016] The present invention, which has the above-mentioned features, provides guidance for the sliding of the lock cover by the U-shaped groove and the first waist-shaped groove, and prevents the lock cover from shifting.

[0017] A further feature of this invention is that the outer circumferential surface of the lock body is provided with an arc-shaped groove that is adapted to the second mounting stud.

[0018] The present invention with the above features: the arc-shaped groove design increases the contact area between the second mounting stud and the lock body, ensuring that the second mounting stud can always abut against the lock body during the self-adjustment process of the lock cover.

[0019] A further feature of this invention is that a reset seat is provided between the inner and outer handles and the corresponding lock cover to reset the inner and outer handles. The bottom surface of the reset seat abuts against the end face of the lock cover. The reset seat has a recessed groove for mounting the head of the mounting screw and the head of the mounting stud. The lock cover has at least one second waist-shaped groove. The reset seat has an annular boss placed in the second waist-shaped groove. The second waist-shaped groove has a mounting screw that connects the lock cover and the reset seat.

[0020] The present invention, which has the above features, has the following characteristics: the recess can accommodate the head of the mounting screw and the head of the mounting stud, avoiding interference of parts caused by the head being exposed; at the same time, the setting of the reset seat realizes the reset function of the inner and outer handles; the annular boss can slide in the second waist-shaped groove, ensuring that the reset seat will not slide with the lock cover.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0033] When installing a swing door lock, the lock body is embedded into the pre-drilled hole on glass b. The inner and outer handles are then installed on the inner and outer sides of the glass, respectively. The end of the lock cover that rests against the profile after installation is called the limiting end. At this time, the limiting end presses against the protrusion a2 of profile a. When the lock cover is pulled back, the limiting end of the lock cover moves from the protrusion of the profile to the glass surface, and the elastic element is compressed. After the lock cover is released, the lock cover rests against the protrusion of the profile under the elastic force of the elastic element, thus completing the installation of the swing door lock. This self-adaptive lock cover structure is applicable regardless of the size or specification of the profile.
