Description

Technical Field:

[0001] The present invention relates to an integral lock bolt structure for an anti-theft door, belonging to the technical field of anti-theft doors. Background Art:

[0002] Currently, the lock bodies of anti-theft doors all adopt small round or square lock bolts, which are arranged longitudinally in multiple numbers. When locking, the lock bolts extend out, and when unlocking, the lock bolts retract. Due to the small size and limited strength of this kind of lock bolt, even if the anti-theft door is made of thickened steel plates, the safety performance will not be substantially improved. Moreover, this small lock bolt structure has been used for decades without any innovative technological breakthroughs.

[0003] The safety performance of an anti-theft door mainly depends on the strength of the lock body. The more lock bolts, the safer it is, but the failure rate will also increase due to the increase in the number of lock bolts. Therefore, a solution is needed to improve the strength of the lock bolts while reducing the failure rate. Summary of the Invention:

[0004] In view of the above problems, the technical problem to be solved by the present invention is to provide an integral lock bolt structure for an anti-theft door.

[0005] An integral lock bolt structure for an anti-theft door of the present invention includes a door panel, a door frame, a lock case, a lock bolt, a rack, a rack sliding hole, a rack sliding shaft, a lock core gear, a round steel placement hole, a round steel, a synchronous gear, a synchronous rack, and a lock core. A door frame is arranged outside the door panel, a lock case is arranged inside the door panel, the lock bolt is arranged inside the lock case, a rack sliding hole is arranged on the rack, the rack sliding shaft passes through the rack sliding hole and is fixed on the lock case, the rack meshes with the lock core gear, the lock core gear is arranged on the lock core, the lock core is fixed on the lock case, the rack and the lock bolt are riveted into a whole, a round steel placement hole is arranged on the lock bolt, the round steel placement hole runs through the whole lock bolt, the round steel is placed in the round steel placement hole, synchronous gears are welded to the upper and lower ends of the round steel, and the synchronous gears engage with the synchronous rack on the lock case.

[0006] Preferably, a door frame groove is arranged on the door frame and engages with the lock bolt.

[0007] Preferably, the heights of the lock bolt and the lock case are the same as the height of the door panel.

[0008] The beneficial effects of the present invention are as follows: It has a reasonable structural design, is simple to install and convenient to use. By changing multiple small lock bolts into a single integral lock bolt, the height of the lock bolt is the same as the height of the door panel, and a door frame groove corresponding to the lock bolt is arranged on the door frame. When locking, the lock bolt extends out and is inserted into the door frame groove to achieve integral engagement, greatly improving the strength. Brief Description of the Drawings:

[0009] For ease of explanation, the present invention will be described in detail by the following specific embodiments and accompanying drawings.

Specific implementation manner:

[0016] As Figures 1-5 shown, the following technical solutions are adopted in this specific implementation manner: It includes a door panel 1, a door frame 2, a lock housing 3, a lock bolt 4, a rack 5, a rack sliding hole 6, a rack sliding shaft 7, a lock core gear 8, a round steel placement hole 9, a round steel 10, a synchronous gear 11, a synchronous rack 12, and a lock core 13. A door frame 2 is arranged outside the door panel 1, a lock housing 3 is arranged inside the door panel 1, a lock bolt 4 is arranged inside the lock housing 3, and the lock bolt 4 reciprocates horizontally. A rack sliding hole 6 is arranged on the rack 5, and a rack sliding shaft 7 is inserted into the rack sliding hole 6. The rack sliding shaft 7 is fixed on the lock housing 3, playing the role of limiting and bearing. The rack 5 meshes with the lock core gear 8, the lock core gear 8 is arranged on the lock core 13, and the lock core 13 is fixed on the lock housing 3. The rack 5 and the lock bolt 4 are riveted into a whole, and the lock bolt 4 moves horizontally accordingly. A round steel placement hole 9 is arranged on the lock bolt 4, and the round steel placement hole 9 runs through the whole body of the lock bolt 4. A round steel 10 is placed inside the round steel placement hole 9. Synchronous gears 11 are welded to the upper and lower ends of the round steel 10, and the synchronous gears 11 engage with the synchronous rack 12 on the lock housing 3 to limit the synchronous horizontal movement of the upper and lower ends of the lock bolt 4. When the lock core gear 8 rotates, it drives the rack 5 and the lock bolt 4 to move horizontally to achieve unlocking and locking.

[0017] A door frame groove 201 is arranged on the door frame 2 and engages with the lock bolt 4.

[0018] The heights of the lock bolt 4 and the lock housing 3 are the same as the height of the door panel 1.

[0019] When this specific embodiment is in use, the bolt 4 is retracted into the lock housing 3, and the outer sides are flush, and it is in the unlocked state at this time; the lock core 13 is fixed on the lock housing 3. When the key is rotated, the lock core gear 8 on the lock core 13 rotates, driving the rack 5 to move horizontally. The rack 5 is riveted to the bolt 4 as a whole, and the bolt 4 moves horizontally synchronously and is inserted into the door frame groove 201 on the door frame 2 to achieve locking. The key needs to be rotated in the opposite direction to unlock, and the process is reversed.

[0020] This specific embodiment has a reasonable structural design, is simple to install and convenient to use. By changing multiple small bolts into a single integral bolt, the height of the bolt is the same as the height of the door panel, and a door frame groove corresponding to the bolt is provided on the door frame. When locking, the bolt extends out and is inserted into the door frame groove to achieve overall engagement, and the strength is greatly improved.

[0021] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention.
