Description

A gear-driven mortise hook lock

Technical field:

The utility model relates to a mortise door lock driven by a gear, in particular to a mortise hook lock driven by a gear, which belongs to the hardware lock manufacturing industry.

Background technique:

The mortise lock is the most widely used door lock at present, and it is used in offices, people's living rooms, kitchens and toilets. There are two types of general mortise door locks, one is a simple oblique tongue structure, that is, the front and rear handles are connected to the handle block to drive the oblique tongue to move in translation, and the front handle is equipped with a lock head, which can Lock the lock head. The other is a large mortise door lock with oblique tongue and square tongue. The front and rear handles can open and close the oblique tongue and square tongue at the same time, while the front lock head and rear safety knob can lock the lock body. These two kinds of mortise door locks have their own weaknesses. The simple mortise door lock with oblique tongue is not safe enough, and the mortise door lock with oblique tongue and square tongue has weak impact resistance. The utility model finds a new way, overcomes the weakness of the above-mentioned mortise lock, and develops a mortise hook lock with high impact resistance, strong safety and different structure from the current mortise door lock. This utility model is researched and trial-manufactured in this way It worked.

Utility model content: The purpose of this utility model is to provide a gear-driven mortise hook lock, which is to install a driving gear, a driving gear, a connecting piece and a knuckle in the lock body, and the driving gear drives the driving gear to rotate, and the driving gear Connect and drive the hook to achieve the purpose of locking and opening the door.

Detailed ways:

According to each accompanying drawing, manufacture each component of the utility model and assemble. What will be introduced in detail here is that the upper part of the upper lock body 1 and the lower lock body 2 is stamped with an inwardly recessed cylinder---that is, the front and rear lock head and tail chi 11,12. Two superimposed driving gears 13 are just assembled on the inner cylinder walls of the front and rear lock head transmission channels 11,12. The transmission gear 14 is connected on the central stud 14-9 of the upper lock body 1 through the central hole 14-6, and the transmission gear 14 can rotate around the central stud 14-9. Transmission gear 14 is made up of pear shape body 14-1, upper gear plate 14-2 and lower gear plate 14-3, and the three are riveted with two rivets to form a whole. The upper gear teeth 14-4 of the same arrangement are arranged at one end of the upper gear plate 14-2 and the lower gear plate 14-3, and the lower gear teeth 14-5 are arranged at the lower end of the lower gear plate 14-3; therefore, the periphery of the driving gear 13 The gear teeth 13-2 mesh with the upper gear teeth 14-4 of the transmission gear 14. The waist-shaped hole 14-7 of transmission gear 14 is connected on the waist-shaped hole stud 14-10 of upper lock body 1; on the nail 15-3; the waist-shaped hole 15-1 of the connecting piece 15 is connected on the stud 16-5 on the stud hole 16-2 of the knuckle 16; the knuckle 16 is connected on the upper and lower by the pin 16-6 On the inner bottom surface of the lock body 1,2. Like this, when the front lock head is connected on the driving gear 13, open the lock head with a key, the cross bar in the lock head is inserted in the central cross hole 13-3 of the driving gear 13, and then the driving gear 13 is rotated, and the driving gear 13 is connected with the transmission The gear 14 meshes, so it drives the transmission gear 14 to rotate, and the transmission gear 14 translates the rotating piece 15 through the stud 15-3 connected to its end during the rotation; The stud 16-5 on the shaped hole 15-1 is pushed upwards, so that the knuckle 16 rotates 90° around the pin 17, and the sharp hook 16-1 at the front end of the knuckle 16 passes through the knuckle hole of the fixed plate 18 18-1 and the knuckle hole 3-1 of the backing plate 3 enter into the knuckle groove of the door frame, and there is a fence in the groove, which can prevent the knuckle 16 from moving slightly, so the door leaf is strongly protected function without being opened. In the same way, turn the key in the opposite direction, and the cross bar in the lock end can still turn the knuckle tongue 16 back in the lock body by the cross hole 13-3 of the driving gear 13, thereby opening the door. Therefore, the utility model is novel in design, abandons the shift fork structure of the mortise lock, and uses the gear transmission to be more stable, reliable and powerful. In addition, a fixed plate 18 of "匸" shape is installed on the inboard of upper and lower lock bodies 1, 2, thereby improving the impact resistance of the lock body, so that the lock body and the knuckle can bear the impact force of 500kg without Being damaged, anti-drilling, anti-saw, anti-steel wire hooking at the same time, its safety performance is excellent. The oblique bolt structural system of lock body bottom is identical with prior art, just no longer narrate. The utility model also has a kind of structural form, promptly only has gear transmission part simply, adopts hook tongue 16 to open and close the door simply, and does not have oblique tongue structural part. Can choose the product of which structure to use like this according to the demand of consumer, but its structure and principle of two kinds of hook locks are identical, all should be among the protection of this patent.
