Description

Technical Field

[0001] This utility model relates to the field of door locks, and more specifically, to a novel flat lock. Background Technology

[0002] Currently, most door locks on the market are unlocked by pressing down on the door handles on both the inside and outside of the door, which causes the bolt to retract into the lock body, thus opening the door.

[0003] For example, Chinese utility model patent with announcement number CN216553384U discloses a new type of eco-friendly door lock, including an inner handle seat fixed to the inner door panel, an outer handle seat fixed to the outer door panel, an inner handle, an outer handle, and a square shaft with both ends connected to the inner handle and the outer handle respectively, enabling the inner handle and the outer handle to move together; the inner handle is rotatably mounted on the inner handle seat, and the outer handle is rotatably mounted on the outer handle seat;

[0004] Both the inner and outer door handles protrude from the outside of the door panel, making it easy for people to bump into the handles or even get their clothes caught, posing a safety hazard. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of flat lock.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A novel flat lock includes a lock body with panels on both the inner and outer sides. The lock body includes a lock shell and a bolt slidably disposed within the lock shell. A magnet is built into the front end of the bolt, and a drive shaft is connected to both the inner and outer sides of the rear end of the bolt. One end of the drive shaft extends out from the lock shell.

[0008] One end of the panel is provided with a handle that is rotatably mounted on a pivot, and a reset torsion spring is provided on the pivot to drive the handle to return to its original position.

[0009] The handle is provided with an unlocking foot at the rear end, which extends from below the panel and is positioned at the front end of the drive shaft.

[0010] Pulling the front end of the handle upwards causes the rear end of the handle to compress the reset torsion spring downwards, and the unlocking foot rotates downwards to push the transmission shaft to move backwards. The transmission shaft then drives the lock tongue to retract back into the lock housing.

[0011] The present invention is further provided with: a limiting foot is provided at the rear end of the handle, a limiting groove is provided on the panel, and the limiting foot is placed in the limiting groove;

[0012] Pulling the handle upward causes the limiting foot to rotate downward, causing it to abut against the limiting groove and preventing the handle from rotating further.

[0013] The present invention further comprises: the reset torsion spring is sleeved on the rotating shaft, with one end abutting against the panel and the other end abutting against the lower end surface of the handle's rear end.

[0014] The present invention further includes: a mounting hole at the rear end of the locking tongue, and a connecting hole on the drive shaft;

[0015] The fasteners consist of a connection hole for one drive shaft, a mounting hole for another drive shaft, and a connection hole for the third drive shaft, which secure the two drive shafts to the latch.

[0016] The present invention further includes: a deadbolt assembly is provided inside the lock housing, the deadbolt assembly includes a slidably disposed locking member and a rotatably disposed pushing member, and the pushing member is provided with a pushing foot;

[0017] The locking member has a locking protrusion at one end and a mating groove at the other end that engages with the push foot.

[0018] Rotating the pusher causes the push foot to rotate upwards, which in turn abuts against the upper end of the mating groove and pushes the locking member upwards, placing the anti-locking protrusion behind the bolt to prevent the bolt from retracting into the lock housing. Reversely rotating the pusher causes the push foot to abut against the lower end of the mating groove and pushes the locking member downwards, causing the anti-locking protrusion to be misaligned with the bolt and releasing the bolt from locking.

[0019] The present invention is further configured such that one end of the pusher is connected to the deadbolt knob on the panel inside the door, and the other end is connected to the lock cylinder on the panel outside the door.

[0020] The beneficial effects of this utility model are as follows: The handle of the flat lock is rotatably mounted in the mounting groove recessed under the panel via a pivot. In its natural state, the handle is completely flush with the surface of the panel and is flush with the outer surface of the panel. This can prevent the handle from snagging on clothing, prevent people from colliding with the handle, eliminate safety hazards, and at the same time make the appearance of the door lock more simple and beautiful.

[0021] When unlocking, simply pull the front end of the handle upwards. The unlocking foot rotates downwards, pushing the transmission shaft to move backwards. This transmission shaft causes the bolt to retract back into the lock case, making the unlocking operation simpler. This flat lock achieves direct transmission between the unlocking foot at the lower end of the handle and the transmission shaft of the bolt, simplifying the transmission structure between the handle and the bolt and effectively reducing the production cost of the flat lock.

[0032] See attached document Figures 1 to 9 This utility model provides a further detailed description of a novel flat lock.

[0033] A novel flat lock includes a lock body 1, with panels 2 on both the inner and outer sides of the lock body 1. The lock body 1 includes a lock shell 11 and a bolt 12 slidably disposed within the lock shell 11. A magnet is built into the front end of the bolt 12. After the door is closed, the bolt 12 will automatically extend from the lock shell 11 and be placed in the latch box of the door frame under the magnetic force of the latch box containing the magnet. A drive shaft 121 is connected to both the inner and outer sides of the rear end of the bolt 12, with one end of the drive shaft 121 extending out of the lock shell 11.

[0034] One end of the panel 2 is rotatably mounted with a handle 22 via a pivot 21. A return torsion spring 23 is mounted on the pivot 21 to drive the handle 22 back to its original position. The handle 22 of the flat lock is rotatably mounted in a recessed mounting groove 26 on the panel 2 via the pivot 21. In its natural state, the handle 22 is completely flush with the surface of the panel 2 and is flush with the outer surface of the panel 2. This prevents the handle 22 from snagging on clothing, avoids collisions between people and the handle 22, eliminates safety hazards, and makes the appearance of the door lock more simple and beautiful.

[0035] The handle 22 is provided with an unlocking foot 221 at the rear end, and the unlocking foot 221 extends from below the panel 2 and is located at the front end of the drive shaft 121.

[0036] When unlocking, simply pull the front end of the handle 22 upwards. The rear end of the handle 22 compresses the return torsion spring 23 downwards, and the unlocking foot 221 rotates downwards, pushing the transmission shaft 121 to move backwards. The transmission shaft 121 drives the bolt 12 to retract into the lock case 11, making the unlocking operation simpler. This flat lock achieves direct transmission between the unlocking foot 221 at the lower end of the handle 22 and the transmission shaft 121 of the bolt 12, simplifying the transmission structure between the handle 22 and the bolt 12 and effectively reducing the production cost of the flat lock.

[0037] The handle 22 is provided with a limiting foot 222 at its rear end, and the panel 2 is provided with a limiting groove 24. The limiting foot 222 is placed in the limiting groove 24. When the handle 22 is pulled upward, the handle 22 drives the limiting foot 222 to rotate downward, so that the limiting foot 222 abuts against the limiting groove 24, preventing the handle 22 from continuing to rotate, limiting the rotation angle range of the handle 22, and protecting the flat lock accessories.

[0038] The reset torsion spring 23 is sleeved on the rotating shaft 21, with one end abutting against the panel 2 and the other end abutting against the lower end face of the rear end of the handle 22. After unlocking, the compressed reset torsion spring 23 will push the rear end of the handle 22 upward, causing the front end of the handle 22 to rotate downward and re-fit against the panel 2.

[0039] The locking tongue 12 has a mounting hole 122 at its rear end, and the drive shaft 121 has a connecting hole 1211.

[0040] The fasteners are connected to the connection hole 1211 of one drive shaft 121, the mounting hole 122, and the connection hole 1211 of the other drive shaft 121 in sequence, fixing the two drive shafts 121 to the locking tongue 12.

[0041] The lock housing 11 is provided with a deadbolt assembly 3, which includes a slidably disposed locking member 31 and a rotatably disposed pushing member 32. The pushing member 32 is provided with a pushing foot 321. The pushing member 32 is provided with a positioning torsion spring, which locks the pushing member 32 in the deadbolt position and the unlocked position.

[0042] One end of the locking member 31 is provided with a deadbolt 311, which faces the locking tongue 12; the other end is provided with a mating groove 312 that mates with the push foot 321, which faces the push foot 321.

[0043] Rotating the pusher 32 causes the push foot 321 to rotate upwards. The unlocking foot 221 abuts against the upper end of the mating groove 312 and pushes the locking member 31 to slide upwards, so that the anti-locking protrusion 311 is positioned behind the bolt 12 to prevent the bolt 12 from retracting into the lock case 11, thereby achieving the anti-locking of the door lock. Rotating the pusher 32 in the opposite direction causes the push foot 321 to abut against the lower end of the mating groove 312 and pushes the locking member 31 to slide downwards, so that the anti-locking protrusion 311 is misaligned with the bolt 12, thereby releasing the lock on the bolt 12 and unlocking the door lock.

[0044] One end of the pusher 32 is connected to the deadbolt knob 25 on the inner panel 2 of the door, and the other end is connected to the lock cylinder on the outer panel 2 of the door. The person inside the door can lock or unlock the door by rotating the deadbolt knob 25, and the person outside the door can lock or unlock the door by using a key to drive the lock cylinder to rotate.

[0045] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
