A single bolt mortise lock controlled by a safety button

Technical field:

The utility model relates to a mortise lock, in particular to a single bolt mortise lock controlled by a safety button, which belongs to the hardware lock manufacturing industry.

Background technique:

Mr. Wu Junyi, the patent inventor in Zhongshan City, Guangdong Province, China, has been engaged in the production of hardware locks for more than 20 years, and has accumulated rich experience in manufacturing and producing mortise door locks. In recent years, the continuous research and development of new mortise door locks has provided a new way for the manufacture, production and use of mortise door locks. At the end of 2007, he developed and applied for two utility model patents, one is "a gear-driven mortise hook lock", the application number is 200720179157.0, and the other is "with driven gear, sliding plate and paddle mortise hook lock," the application number is 200820043391.5. Its purpose is to improve the impact resistance and safety performance of the mortise door lock. On this basis, Mr. Wu Junyi continued to develop a mortise door lock with dual-mode functions of family mode and security mode, which can make the mortise door lock anti-saw, anti-drilling and anti-technical unlocking to meet higher requirements, and at the same time, it is more humane To meet the needs of consumers in general, this is the original intention of the utility model research and development.

Utility model content:

The utility model assembles an anti-insertion tongue, a locking bolt and a safety button in the lock body, and through the control of the safety button on the slide and the synergistic effect of the paddles, the dual-mode functions of the family mode and the safety mode can be realized.

Detailed ways:

Make each component of the utility model and assemble according to accompanying drawing 1 and each accompanying drawing. Describe the structure of the present utility model below with reference to accompanying drawing 1 and accompanying drawing 2, assemble safety button plectrum 20-1 on the inner bottom surface of the safety button hole 2-1 of liner plate 2, at this moment safety button post 20-3 is to stretch Out of the safety buttonhole 2-1 of the backing plate 2, the plectrum 20-1 can be pushed down or pulled up by the column cap 20-3 with a finger. The slide plate 21 is connected to the two studs 23 and 24 on the bottom surface of the lock body 1 through the upper and lower waist-shaped holes 21-2 and 21-3, and the fixing hole 21-4 is connected to the lock head fixing plate 25 perpendicular to the bottom surface of the lock body 1 Top; the nail 21-5 at the left end of the slide plate 21 is plugged into the nail hole 20-2 on the top of the safety button dial 20-1; -1, the other end leans against the inner wall of the side of the lock body 1. The safety button stigma 20-3 can be pulled down or extracted upwards by fingers, and the slide plate 21 can be slid downward or translated upward, very freely. The pick 22 is a narrow long plate, which is connected to the stud 27 on the bottom surface of the lock body 1 through the connecting hole 20-1, and the pick 20 passes through the bottom surface of the lock body 1, and the pick head 22-2 at the front end is horizontally Stacked on the plane of the lower part of the slide plate 20, and close to the block 21-6 of the slide plate 20. Looking down from the upper part of the lock body 1, the lock head drive channel 11 is assembled in the upper and lower lock head drive seat 9, 10, the lock head oblique bolt 5 is connected in the oblique tongue hole 2-2 of the lining plate 2, and the oblique bolt The inner end of the pull bar stopper 7 abuts against the right side of the plectrum head 22 - 2 of the plectrum 22 . The latch tongue spring 8 is sleeved on the stud 23 and placed on the slide plate 21 , one end is hooked on the latch tongue 5 , and the other end leans against the inner wall of the lock body 1 side. The anti-insertion tongue 3 is connected in the anti-insertion tongue hole 2-3 of the liner 2, the anti-insertion tongue 3 and the lock bolt 5 are connected on the safety tongue bracket 28, and the safety tongue bracket 28 is connected on the anti-insertion tongue shell plate 29 above. The safety card plate 30 is connected to the stud 31 in the middle of the lock body 1 through its rotation hole 30 - 1 and mounted on the bolt pull rod 6 and the safety tongue bracket 28 . The anti-insertion spring 32 is located at the bottom of the lock body 1 and is sleeved on the stud 33. Its longer end is hooked in the oval hole 30-2 of the safety clamp 30, and the other end is attached to the inner wall of the lock body 1 side. From here we can see that: when the house owner inserts the lock 18 through the key, the lock drive 11 rotates counterclockwise so as to push the plectrum head 22-2 of the plectrum 22 to press down, and the plectrum 22 presses down to move and push The oblique tongue 5 of the lock body and the anti-insertion tongue 3 retract into the lock body 1 at the same time. After both retracted in the lock body 1 fully, promptly the lock body oblique tongue spring 8 and the anti-insertion tongue spring 32 were compressed to the maximum value, and now the action of unlocking with the key is completed once. On the contrary, when the active force on the lock transmission channel 11 disappears, the oblique tongue spring 8 and the anti-insertion tongue spring 32 stretch back to the original state, and the plectrum 22, the anti-insertion tongue shell plate 29 and the oblique tongue pull rod 6 are subjected to the oblique action. The upward pushing force of the tongue spring 8 and the anti-insertion tongue spring 32 pushes the oblique tongue 5 of the lock body and the anti-insertion tongue 3 out of the lock body 1; Turn clockwise, and a locking action is completed at this time. Here it is the safe mode state of the present utility model. When the house owner enters the door on a holiday or during the day, he can press the lock bolt 5 and the anti-insertion tongue 3 into the lock body 1, and push the safety button column head 20-3 with his fingers, so that the slide plate 21 moves forward in the lock body 1. Slide down, at this moment, the block 21-6 of the slide plate 22 just falls on the inner side of the block 7 of the oblique tongue pull rod 6 of the lock head, and the oblique bolt pull rod 6 is blocked, and the oblique bolt 5 and the anti-insertion tongue 3 are retracted into the lock body 1, at this moment the owner of the house can freely enter and exit the door without being hindered by the oblique tongue 5, and it is very convenient not to twist the handle many times to open the door. When the night house owner is going to have a rest, the safety button stigma 20-3 can be promoted upwards, and at this moment the slide plate 22 moves upwards, and the block 21-6 of its lower right end just comes out from the inside of the oblique tongue pull bar block 7, and locks The head oblique bolt 5 stretches out of the lock body 1 again and enters in the deadbolt hole of the doorframe, and the door is closed, which plays a role of security. Finally, once there is a dangerous emergency, a fire or an earthquake, the house owner only needs to put on his clothes and press the rear handle 19 in a clockwise direction, and the door will open instantly, thereby quickly escaping to the stairwell. At this time, the rear handle 19 moves the handle toggle plate 13, and the handle toggle plate 13 pushes the toggle button 35, and the toggle knob 35 drives the release plate 36 to rotate, and the release plate 36 drives the safety clamp plate 30 to rotate counterclockwise. Thereby the oblique tongue pull bar stopper 7 that is connected on the safety clamp 30 is promoted to the right, makes the deadbolt oblique tongue 5 indent in the lock body 1, and the door is just opened rapidly like this, and this is the function that rear handle 19 opens the door. Similarly, when the rear handle 19 is lifted (counterclockwise) and swings, the oblique tongue 5 will stretch out again to obtain the function of closing the door.
