Description

Door handle with prevent tong function

Technical Field

The utility model relates to a door handle especially relates to a door handle with prevent tong function.

Background

The door handle is a very common security article in the present life, and the door handle can be divided into an indoor lock and a security door lock according to different use scenes.

Although the lock is convenient, in the family that has the young children at home, the experience that the finger was pressed from both sides to be hindered by the door has all taken place for a lot, and serious meeting causes the finger fracture, causes the damage to children's health, how can be on the door to the children more a heavy guarantee, it is the present problem that awaits the solution to avoid children's finger to be pressed from both sides to be hindered by the door.

SUMMERY OF THE UTILITY MODEL

For solving the problem that prior art exists with not enough, the utility model aims at providing a door handle with prevent tong function.

The utility model provides a door handle with prevent tong function, includes the door handle body and prevents tong device, and the door handle body includes panel and handle, and panel fixed mounting is on the door, and the handle is installed on the panel, prevents that tong device middle part is equipped with the pilot hole, and the handle passes the pilot hole and prevents the assembly of tong device.

Further, prevent tong device includes casing, link gear and prevents tong baffle, and link gear sets up in the casing, prevents that tong baffle is connected with link gear, and the casing is installed on the panel, drives link gear when the handle rotates, and link gear drives and prevents tong baffle rotation.

Further, the link gear includes driving gear, first driven gear and second driven gear, and the driving gear setting is between first driven gear and second driven gear, and the driving gear middle part is equipped with the connecting hole, and the handle passes the connecting hole and is connected with the driving gear.

Furthermore, the side of the shell is provided with a sliding chute used for preventing the hand from sliding of the baffle.

Further, the first driven gear and the second driven gear are both semicircular gears.

Furthermore, the inner wall of the shell is positioned above the first driven gear and the second driven gear and is also provided with a limiting protection block.

Furthermore, the limiting protection block is made of rubber.

The utility model discloses an useful part lies in:

add on traditional door handle and prevented tong device, when the door handle did not receive exogenic action, prevent that the tong baffle among the tong device is horizontal state, and its length surpasss a body edge, when closing at this moment when folding, will have between door frame and the door to prevent that the tong baffle blocks. And when the door handle receives external force and rotates certain angle, prevent that tong baffle rotates simultaneously, is vertical state after rotating, at this moment, when the door is closed and folds, just no longer have between door frame and the door and prevent that tong baffle blocks, can close smoothly. The design can ensure that the door can be completely closed when operated by people, and the anti-pinch baffle can ensure that the door cannot be completely closed when the door is not closed artificially.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

The utility model provides a door handle with prevent tong function, includes the door handle body and prevents tong device, and the door handle body includes panel 2 and handle 1, and panel fixed mounting is on the door, and the handle is installed on the panel, prevents that tong device middle part is equipped with the pilot hole, and the handle passes the pilot hole and prevents tong device assembly. Prevent tong device includes casing 3, link gear and prevents tong baffle 4, and link gear sets up in the casing, prevents that tong baffle and link gear are connected, and link gear rotates and drives simultaneously and prevents tong baffle and rotate, and the casing is installed on the panel, drives link gear when the handle rotates, and link gear drives and prevents tong baffle and rotate.

The linkage mechanism comprises a driving gear 5 which is provided with a gear wheel, first driven gear 6 and second driven gear 7, the driving gear setting is between first driven gear and second driven gear, the driving gear middle part is equipped with connecting hole 101, the handle passes the connecting hole and is connected with the driving gear, the handle rotates and drives the driving gear rotation, the driving gear rotates and drives first driven gear and second driven gear rotation simultaneously, first driven gear is located the driving gear top, second driven gear is located the driving gear below, the driving gear clockwise turning is about 30 to 45, first driven gear anticlockwise rotation is about 90, second driven gear anticlockwise rotation is about 90, prevent that tong baffle is connected on first driven gear and second driven gear, drive first driven gear and second driven gear rotation along with the driving gear, prevent tong baffle also from horizontal state adjustment for vertical longitudinal condition.

The side of the shell is provided with a sliding chute 8 used for preventing the hand from sliding of the baffle. The first driven gear and the second driven gear are both semi-circular gears. The semicircular structure can reduce the space required by the anti-pinch device, so that the device is smaller.

The inner wall of the shell is positioned above the first driven gear and the second driven gear and is also provided with a limiting protection block 9. The limiting protection block is made of rubber. When the limit protection block receives the impact and plays a role in protection, the impact force easily causes the assembly structure to be loosened, therefore, the limit protection block is arranged above the first driven gear and the second driven gear on the inner wall of the shell, the bounce of the anti-pinch baffle can be reduced when the anti-pinch baffle is impacted, and the loosening is avoided.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims.
