Description

A new type of door handle lock

technical field

The utility model belongs to a lockset, in particular to a spherical door lock.

Background technique

Existing spherical door locks include lock body, lock cylinder, inner and outer ball handles, inner and outer discs, spring seats, square tubes, dead bolts, etc., wherein the inner and outer discs are installed on the front and rear of the lock body respectively, and two baffle plates The distance is equal to the thickness of the door. The spring seat is fixedly connected with the square tube, and the square tube is connected with the lock tongue. After the key is inserted into the lock cylinder and opened, turn the door handle to drive the spring seat, square tube and lock tongue to move together, so that the lock tongue shrinks. Insert the lock body and finally open the door. The disadvantage of this kind of door lock is: the spring seat is fixedly connected with the square tube, and the square tube cannot be rotated independently. Because the square tube plays the role of driving the lock tongue, this kind of lock can only be A purely mechanical lock. In recent years, the application of electronic door locks has become more and more widespread. Locks with purely mechanical functions can no longer meet the needs of the market. It is an urgent need to design a door lock that is suitable for both mechanical and electronic structures.

Contents of the invention

The technical problem to be solved by the utility model is: on the basis of the existing door handle lock, provide a new type of door lock which is suitable for both mechanical structure and electronic structure.

In order to solve the above technical problems, the utility model adopts the following further technical solutions: a new door handle lock, including lock core, inner and outer ball handles, inner and outer discs, twist seat, bachelor's cap, spring seat, square pipe, deadbolt , is characterized in that: the square tube is detachable from the spring seat and can rotate within it.

The bachelor cap is additionally provided with a fixed piece, and the fixed piece is provided with hanging ears and a through hole matching the outer diameter of the square tube.

The end of the square tube extending into the spring seat is provided with a limiting piece, and a section of the end of the square tube protrudes from the limiting piece.

It can be seen from the above-mentioned technical scheme that the square tube driving the deadbolt of the lock of this structure can be rotated independently with other mechanical mechanisms, making it a door lock suitable for both mechanical structure and electronic structure, and this structure The lock is a transformation of the existing technology, and its transformation cost is low, so it is suitable for popularization and application.

Detailed ways

Referring to Fig. 1, the utility model is the improvement to prior art, and it is made of lock core 1, outer ball handle 2, outer handle cover 3, outer jacket disc 4, outer tube 5, central rod 6, twist seat 7, bachelor's cap 8. Fixed piece 9, spring 10, spring seat 11, square tube 12, deadbolt connected with square tube 12 (not shown in the figure), twist handle 13, inner tube 14, inner disc 15, inner handle cover 16. The inner ball handle 17 is assembled sequentially. The improvement is that when the door lock is closed, the square tube 12 is detachable from the spring seat 11 and can rotate therein.

Referring to Fig. 2 and Fig. 3, the end of the square tube 12 extends into the spring seat 11 through the central hole, and can rotate therein. The effect of stopper 18 is to limit the end of square tube 12 in spring seat 11, can not extract out, and the end of square tube 12 has a section to stretch out stopper 18, and additionally is provided with fixed piece 9 on the bachelor's cap 8, fixes The sheet 9 is provided with hanging ears 19 , which are the same as the hanging ears 20 on the bachelor's cap 8 , and the fixed sheet 9 is provided with a through hole 21 matching the outer diameter of the square tube 12 .

Referring to Fig. 3, when the door lock is in the closed state, the knob seat 7 is overlapped with the bachelor cap 8, the spring 10 is in a free state, and the two lugs of the bachelor cap 8 and the fixing piece 9 are embedded in the groove 22 of the outer casing , the door handle cannot be rotated, and at this moment, the square pipe 12 can drive the dead bolt to rotate independently.

Referring to Fig. 4, when the door lock is in the open state, rotating the lock cylinder 1 drives the center rod 6, and the center rod 6 drives the rotary seat 7 to rotate, and the bachelor's cap 8 is lifted up, and at the same time, the fixed piece 9 is also pushed up , spring 10 is compressed, and the end of square pipe 12 falls in the through hole 21, and this moment square pipe 12 is fixed by fixed piece 9 and can not rotate independently, but can rotate with door handle, drives dead bolt and the door is opened.

As can be seen from the above technical scheme, when the door lock is closed, there are two ways to open the door, one is to use a key to rotate the lock cylinder 1, so that the square tube 12 is fixed, and the door is opened with the door handle driving the dead bolt; Method is to drive the square pipe 12 that can rotate independently with motor, drives dead bolt and the door is opened.

The unique structure of the utility model makes it a door lock suitable for both mechanical structure and electronic structure.
