AI Technical Summary

Technical Problem

Existing swing door locks lack physical positioning points in the sliding engagement between the push plate and the protrusion, resulting in a vague operating feel and easy accidental triggering due to vibration or gravity.

Method used

A tactile positioning anti-slip swing door lock was designed. By setting a protrusion at the lower end of the pusher to contact the abutment of the inner handle, the mechanical resistance changes to produce a "click" sound or a tactile jerking, achieving a clear tactile feel for locking and unlocking. The symmetrical linkage and guide bar structure prevents accidental rebound or sliding caused by vibration or gravity.

Benefits of technology

It provides a clear locking and unlocking feel, enhances anti-slip capability, avoids unexpected rebound due to vibration or gravity, and improves operational stability and structural strength.

DETAILED DESCRIPTION

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figures 1 to 6 The touch-sensitive positioning anti-slip swing door lock shown includes a square bar 1, an inner panel 2 mounted on the door body, and an outer panel (not shown in the attached diagram). The inner panel 2 is rotatably connected to an inner handle 3, and the outer panel is rotatably connected to an outer handle 4. One end of the square bar 1 is linked to the inner handle 3, and the other end is linked to the outer handle 4. A pusher 5 is slidably engaged within the inner handle 3, and the pusher 5 is linked to a deadbolt assembly. A protrusion 5b is provided at the lower end of the pusher 5, and a corresponding abutment 6 is provided on the inner handle 3. When the pusher 5 slides, its lower protrusion 5b contacts the abutment 6 of the inner handle 3, resulting in a change in mechanical resistance (such as a "click" sound or a slight tactile feedback), thus providing a tactile feel for locking and unlocking. Furthermore, when the pusher 5 moves to the locked / unlocked position, the protrusion 5b and the abutment 6 form a physical lock, preventing the pusher 5 from accidentally springing back or sliding due to door vibration or gravity.

[0033] The lower end of the pusher 5 is connected to two sets of opposing connecting rods 5a. Each set of connecting rods 5a has a protrusion 5b on its side facing the other set of connecting rods 5a. The abutment 6 is distributed between the two sets of connecting rods 5a. The two sets of connecting rods 5a are symmetrically distributed at the lower end of the pusher 5, forming a balanced support structure. When the pusher 5 moves, the force is evenly distributed, avoiding unilateral deviation or jamming. At the same time, the symmetrical design of the two sets of connecting rods 5a can offset the lateral interference of door closing vibration or external impact on the pusher 5, enhancing its anti-slip capability.

[0034] The abutment 6 is cylindrical, and all four sides of the cylindrical shape are rounded. The rounded corners of the abutment 6 form a smooth transition surface, which reduces the frictional resistance of the sharp edges when the protrusion 5b of the pusher 5 contacts the abutment 6, making the protrusion 5b slide more smoothly.

[0035] The inner handle 3 has two sets of spaced-apart guide bars 3a. The pusher 5 is positioned between the two sets of guide bars 3a. Wing plates 5c are provided on both sides of the pusher 5, abutting against the upper surfaces of the guide bars 3a. The two sets of guide bars 3a form parallel tracks, restricting the pusher 5 to move only in a preset direction, preventing deviation or jamming. Simultaneously, the guide bars 3a act as reinforcing ribs, enhancing the structural strength of the inner handle 3. The contact between the wing plates 5c and the upper surfaces of the guide bars 3a further improves the smoothness of the pusher 5's movement.

[0036] The flat door lock further comprises a plastic piece 7 for mounting the reverse locking assembly, the upper portion of the inner handle 3 is provided with a first accommodating cavity 3b, the handle is further provided with a second accommodating cavity 3c in communication with the first accommodating cavity 3b, the plastic piece 7 is mounted in the first accommodating cavity 3b, the pusher 5 is slidingly arranged in the second accommodating cavity 3c, and the end face of the plastic piece 7 is provided with a sliding groove for the sliding of the pusher plate. In the prior art, the structure corresponding to the plastic piece 7 is integrally formed with the inner handle 3, which is difficult to be demolded by die casting and has high cost, so the plastic piece 7 is changed in the present application to form an independent functional module, which is convenient for quick installation or replacement and reduces the complexity of maintenance. At the same time, compared with metal materials, the plastic piece 7 has low material cost and lock body weight, is suitable for injection molding process, and is suitable for mass production. The first accommodating cavity 3b is used for mounting the plastic piece 7, the second accommodating cavity 3c is used for mounting the pusher 5, and the sliding groove is arranged on the plastic piece 7 to facilitate the linkage of the pusher 5 and the reverse locking assembly and better control the locking or unlocking.

[0037] The second accommodating cavity 3c is further provided with a positioning plate 8 arranged on the end face of the plastic piece 7 and the end face of the pusher 5, the upper portion and the lower portion of the positioning plate 8 are both provided with a connecting hole 8a, the plastic piece 7 is provided with an auxiliary connecting hole 7a corresponding to the connecting hole 8a in the upper portion of the positioning plate 8, and the abutting piece 6 is provided with an internally threaded connecting hole 6a corresponding to the connecting hole 8a in the lower portion of the positioning plate 8. The positioning plate 8 not only fixes the plastic piece 7 in the second accommodating cavity 3c, but also limits the pusher 5, so that the pusher 5 is stably kept in the sliding groove in the second accommodating cavity 3c and will not fall out of the inner handle 3. The connecting hole 8a, the auxiliary connecting hole 7a and the inner handle 3 are connected by screws, so as to realize the fixation of the positioning plate, the plastic piece 7 and the inner handle 3. The lower end of the positioning plate 8 is fixedly connected with the connecting hole 8a and the internally threaded connecting hole 6a of the abutting piece 6 by screws.

[0039] When locking, the pusher 5 moves up, the first inclined surface 5d presses the lock rod 9 until the lock rod 9 is inserted into the lock eye 2a, the inside handle 3 cannot rotate, and the lock rod 9 will compress the first reset spring 11, completing the locking. When unlocking, remove the outside handle cover 4b, press the outside unlocking rod 10 with your hand, the outside unlocking rod 10 will move the pusher 5 down through the second inclined surface 5e (at the same time, the outside unlocking rod 10 will press the second reset spring 12), so that the second reset spring 12 drives the lock rod 9 to reset, completing the unlocking, and the second reset spring 12 will drive the outside unlocking rod 10 to reset when the hand releases the outside unlocking rod 10. No matter the process of locking or unlocking, the protrusion 5b and the abutting piece 6 will make a "click" sound or a hand feeling, so that the locking or unlocking will have a hand feeling.

[0040] The pusher 5 is provided with a push block 5f below. It is convenient for the hand to drive the pusher 5 to move up and down.
