[0030] The present invention is described in detail below in conjunction with the accompanying drawings.

[0031] Example 1

[0032] like Figure 1 , Figure 2 As shown, the technical solution adopted by the present invention is as follows:

[0033] A lock catch structure comprises: a lock tongue 1, a lock core 2, a rotating rod 3, a door panel 4, a lock housing 5 and a pair of hook components 6. A connecting block 7 is provided at one end of the lock core, one side of the connecting block is connected to the lock tongue for driving the lock tongue to reciprocate, and a rack 8 is provided on one side of the lock tongue; a gear 9 is provided on the rotating rod, the gear meshes with the rack, and the pair of hook components are disposed at both ends of the rotating rod. The lock housing is fixed to the door panel, and the lock core is installed in the lock housing. A through hole 10 is provided on the lock core for facilitating the installation of the lock tongue; a rear cover 11 is provided at the rear end of the lock housing. A convex column 12 is provided on the connecting block, and the convex column is installed on the outer edge of the connecting block. A transverse slide groove 13 is provided on one side of the lock tongue for facilitating the insertion of the convex column. The lock hook of this embodiment is used to hook a window, etc.

[0034] The hook assembly includes a lock hook 14 and a fixing seat 15, and the lock hook is rotatably mounted in the fixing seat. The lock hook includes a fixing cylinder 16 and a hook body 17 fixedly connected to the fixing cylinder. One side of the fixing cylinder is rotatably inserted into the fixing seat, and one end of the rotating rod is fixed in the fixing cylinder. One side of the fixing seat is fixed to the door panel. The hook body of this embodiment can also be equipped with a torsion spring structure to achieve automatic rebound. After unlocking, the hook on the hook assembly automatically rebounds to its position, and the door will be automatically locked when it touches the door. The fixing cylinder has a mounting groove adapted to the rotating rod.

[0035] It should be noted that in this embodiment, the cross section of the rotating rod is rectangular.

[0036] When this embodiment is implemented, the lock core rotates, driving the connecting block to rotate. The eccentric wheel principle converts the rotation of the key into the rotation of the connecting block, causing the lock tongue to slide back and forth along the perforation. The gear rack structure converts the parallel movement of the lock tongue into the gear rotational motion, thereby driving the rotating rod to rotate and driving the lock hook to rotate to realize the opening and closing of the lock.

[0037] Example 2

[0038] A locking structure, comprising:

[0039] A lock tongue;

[0040] A lock core; a connecting block is installed at one end of the lock core, one side of the connecting block is connected to the lock tongue for driving the lock tongue to reciprocate, and a rack is provided on one side of the lock tongue;

[0041] a rotating rod; a gear mounted on the rotating rod, the gear meshing with the rack; and

[0042] At least one hook assembly is mounted on the rotating rod.

[0043] Example 3

[0044] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the difference between Example 3 and Example 1 is that the lock structure also includes an automatic locking component 18, a battery 19, a fixed conductive block 20, a brush sheet 21, a control switch 22 and a buzzer 23. The battery and the fixed conductive block are fixed on the inner side of the door panel. The battery is connected to the fixed conductive block, the brush sheet, the automatic locking component, the control switch and the buzzer in sequence through a wire. One end of the brush sheet is electrically connected to the fixed conductive block. The rotating rod is a hexagonal prism. The rotating rod includes a fixing member 24 and two sections of insulating members 25 located on both sides of the fixing member. Two alternate edges of the fixing member are respectively provided with an annular first magnet 26 and an annular second magnet 27. The S pole of the first magnet faces outward and the N pole faces inward; the N pole of the second magnet faces outward and the S pole faces inward; the fixing member is also provided with a conductive sheet 34 located in the middle of the second magnet. The brush sheet continuously contacts the conductive sheet. The control switch is installed at one side edge of the door panel. The starting working surface M of the rotating rod (the surface that the sliding block contacts when the key is not inserted) is not provided with a magnet, and the first magnet, the second magnet and the starting working surface are arranged alternately.

[0045] The automatic locking assembly is installed on the rotating rod. The automatic locking assembly includes a fixed cylinder 28 and a sliding block 29 installed in the fixed cylinder. A copper spring 30 is provided between the sliding block and the end wall of the fixed cylinder. The copper spring is used to provide elastic force for the sliding block to contact the surface of the rotating rod. The sliding block is also equipped with a ring-shaped third magnet 31, the S pole of the third magnet faces outward and the N pole faces inward. A hot melt adhesive strip 32 is provided in the center of the third magnet. A heating wire 33 is wrapped in the hot melt adhesive strip. One end of the copper spring is connected to the control switch, and the other end is electrically connected to the heating wire. The end of the heating wire continuously contacts the conductive sheet. The melting point of the hot melt adhesive strip in this embodiment is 90-120°C. The buzzer, battery and brush sheet in this embodiment are all commercially available products.

[0046] In the existing key usage process, when the key is turned excessively and breaks in the lock core, the torsion spring of the lock core automatically rebounds, and the door or window is locked and cannot be opened. It is necessary to wait for professionals to open the door before entering. During this process, the user cannot open the door and enter the room. The user will have to wait outdoors for a long time for the locksmith to arrive.

[0047] When this embodiment is implemented, before the key is inserted, the sliding block is in contact with the starting working surface under the action of the copper spring. As the rotating rod rotates, the rotating rod rotates, and the sliding block contacts the first magnet. Since the contact surface of the third magnet on the sliding block has the same magnetic pole as the contact surface of the first magnet, the sliding block is separated from the surface of the rotating rod. In this way, the user can obviously feel the reduction in resistance, reminding the user that it has been rotated to the appropriate working surface and not to rotate further. Since the working circuit of the buzzer is disconnected, it stops working. When the excessive rotation causes the sliding block to contact the second magnet, the buzzer works again and emits an alarm sound. At this time, the contact surface of the third magnet on the sliding block has the opposite magnetic pole to the contact surface of the second magnet, and the sliding block is adsorbed on the surface of the rotating rod. At this time, the rebound resistance of the rotating rod increases, and the door remains open for a short time. The rebound process of the rotating rod is slowed down and the rebound time is prolonged. During this period, the operator can reverse the key to return it to a normal state, and then turn off the control switch. When the key breaks, the automatic locking assembly, battery, fixed conductive block, brush sheet, control switch and buzzer work for a long time to make the heating wire continue to heat up, and the hot melt adhesive strip melts, so that the contact surface of the third magnet sticks to the contact surface of the second magnet, thus avoiding embarrassing situations such as the user being locked out of the door.

[0048] The above description is only a preferred embodiment of the present invention, and does not limit the patent protection scope of the present invention. Any equivalent structural transformation made by using the contents of the present invention and the drawings, directly or indirectly used in other related technical fields, is also included in the protection scope of the present invention.
