Push-and-pull handle lock

Abstract

The invention discloses a push-and-pull handle lock. The push-and-pull handle lock comprises a lock shell and a push-and-pull handle arranged on the lock shell, and a push-and-pull mechanism is arranged in the lock shell, wherein the push-and-pull mechanism comprises a push-and-pull sliding plate; the two ends of the push-and-pull sliding plate are each provided with a push-and-pull gear assembly,one end of each push-and-pull rack is connected with the push-and-pull handle, the other end of each push-and-pull rack is meshed with a driving gear, and each driving gear is meshed with a driven gear; the two ends of the push-and-pull sliding plate are each provided with multiple tooth holes which are evenly distributed at intervals, and the tooth holes are matched with the driven gears; and two transmission racks which are arranged in a spaced manner are further arranged on the push-and-pull sliding plate, and a square-bar rotating shaft is arranged between the two transmission racks and meshed with the transmission racks. When the push-and-pull handle moves forwards and backwards, the square-bar rotating shaft can be driven to rotate, and then a lock tongue can be driven to stretch out and draw back, so that unlocking or locking is achieved, and the structure is simple; and meanwhile, unlocking or locking can be conducted by changing push-and-pull modes, and the push-and-pull handle lock can be suitable for different location setting modes of doors and door frames.

Description

technical field [0001] The invention relates to the field of locks, more specifically, it relates to a push-pull handle lock. Background technique [0002] The push-pull mechanism of the push-pull handle lock is used to transmit the power of the user to the rotating shaft of the square rod, and the rotating shaft of the square rod drives the lock bolt to expand and contract, so as to realize the unlocking action of the push-pull handle lock. When the structure of the existing push-pull handle lock is complicated, the manufacturing cost will be increased. At the same time, the push-pull mechanism of the general push-pull handle lock can only meet one of the unlocking methods of "left push" or "left pull" or "right push" or "right pull". Therefore, it is necessary to know the position of the door and the door frame before installation. relationship, and according to the preset way of opening the door, to select the corresponding push-pull handle lock; however, in the actual op...

[0002]The push-pull mechanism of the push-pull handle lock is used to transmit the power of the user to the rotating shaft of the square rod, and the rotating shaft of the square rod drives the lock tongue to expand and contract, so as to realize the unlocking of the push-pull handle lock Action, when the structure of the existing push-pull handle lock is complicated, the manufacturing cost is increased, and the push-pull mechanism of the general push-pull handle lock can only meet one of the "left push" or "left pull" or "right push" or "right pull" Therefore, it is necessary to know the positional relationship between the door and the door frame before installation, and select the corresponding push-pull handle lock according to the preset door opening method; however, in the actual operation process, errors due to human misjudgment still occur. The reason is that the push-pull handle lock cannot meet the predetermined requirements, and it needs to be replaced many times before the appropriate push-pull handle lock is installed on the door and window.

Therefore, the generality of the push-pull mechanism of the above-mentioned push-pull handle lock is relatively poor, which brings great inconvenience to the user.
