Description

Technical Field

[0001] The utility model relates to the technical field of door locks, in particular to a handle limit structure for lifting and locking upward. Background Art

[0002] At present, most of the door locks on the market are double lock cylinder structures. The inner door handle and the outer door handle can control the lock tongue through the corresponding lock cylinder to achieve the purpose of opening or locking the door. However, due to the use requirements of indoor doors, especially bathroom doors, the inner side of the door locks used in these occasions is usually also equipped with an anti-locking device (locking device) to completely lock the door lock from the inside, and the door lock cannot be opened from the outside. The locking device is usually controlled by a knob and is set separately. The knob is set on the door lock inside the door. This is separate and independent from the door handle controlling the lock cylinder. The knob makes the overall appearance asymmetrical and not simple inside and outside, and it is necessary to unlock the anti-lock by turning the knob and then unlock it by the inner door handle, which is very inconvenient to use.

[0003] Therefore, the present application provides a door handle assembly that can realize the anti-locking function by lifting the handle. The anti-locking function can be realized by lifting the handle. When opening the door indoors, the anti-locking and unlocking (opening the door) can be released at the same time through the door handle inside. It is easy to use and has a beautiful and simple appearance. Utility Model Content

[0004] The purpose of the utility model is to provide a handle limit structure for lifting up and locking, which has a simple and reasonable design and a stable and firm structure; the product is easy to assemble and reduces the cost; it can be lifted up to achieve locking, and when opening the door indoors, the locking and unlocking (opening the door) can be released at the same time through the door handle inside, which is easy to use and has a beautiful and simple appearance.

[0005] In order to solve the above technical problems, the technical solution of the utility model is:

[0006] A handle limit structure for lifting and locking, comprising an inner door handle, an outer door handle, an inner door lock shell, an outer door lock shell, an inner handle rotating shaft, an outer handle rotating shaft, a slide plate, a connecting rod, and a limit plate;

[0007] The inner door lock shell and the outer door lock shell are relatively arranged at the inner and outer sides of the door leaf and are fixedly connected by fasteners such as screws. The inner sides of the inner door lock shell and the outer door lock shell are both provided with a concave cavity.

[0008] The inner door handle is fixed on the inner door lock housing, and its inner side is connected to the inner handle shaft; rotating the inner door handle can drive the inner handle shaft to rotate;

[0009] The outer handle is fixed on the outer lock housing of the door, and its inner side is connected to the outer handle shaft; rotating the outer handle can drive the outer handle shaft to rotate;

[0010] A disc is provided at the inner end of the inner handle shaft, a lever is provided at the outer edge of the disc, and a square cavity (for installing a square core) is provided in the middle of the disc;

[0011] A disc is provided at the inner end of the outer handle shaft, a limit plug is provided at the outer edge of the disc, and a square cavity (for installing a square core) is provided in the middle of the disc;

[0012] The slide plate is arranged in the concave cavity of the lock shell in the door, a cavity is arranged in the middle thereof, and two stoppers arranged at intervals are arranged on the outer edge thereof; the shifting rod is arranged between the two stoppers.

[0013] The limiting plate is arranged in the concave cavity of the outer lock shell of the door, one side of the limiting plate is provided with a limiting groove, and the other side of the limiting plate is connected with the sliding plate through a connecting rod.

[0014] Briefly describe its anti-locking principle:

[0015] Lifting the inner door handle drives the inner handle shaft to rotate, causing the lever on the inner handle shaft to swing to the right, and then the lever abuts against and pushes the block, causing the slide plate to slide to the right; the slide plate sliding to the right drives the limit plate to slide to the right through the connecting rod, and then the limit groove of the limit plate docks with the limit plug on the outer handle shaft, thereby limiting the rotation of the outer door handle, making it impossible for the outer door handle to rotate and open the door, thus achieving the purpose of anti-locking. Conversely, pressing the inner door handle downward causes the slide plate to slide to the left, and the limit groove of the limit plate disengages from the limit plug on the outer handle shaft, releasing the anti-lock.

[0016] Beneficial effects of the utility model:

[0017] Its design is simple and reasonable, and its structure is stable and firm. The product is easy to assemble, which reduces the cost. It can be locked by lifting it up, and when opening the door indoors, the anti-lock and unlocking (opening the door) can be released at the same time through the door handle inside. It is easy to use and has a beautiful and simple appearance. BRIEF DESCRIPTION OF THE DRAWINGS
