Abstract

The invention discloses a door locking device, and belongs to the technical field of mixing equipment auxiliary devices. The door locking device comprises a device body, wherein a door opening is formed in the device body, two parallel connecting rods are hinged to the device body, the bottoms of the two connecting rods are jointly and fixedly connected with a sealing door matched with the door opening, matched pressing handles are arranged at the tail ends of the two connecting rods, the pressing handles are rotationally connected with U-shaped rods through pin shafts, and the U-shaped rods are rotationally connected with the device body through fixing bases. Through the arrangement of the pressing handles and the connecting rods, the sealing door can be pressed for sealing only by pulling the pressing handles, operation is rapid and convenient, the locking device is fixed through the dead point position, the self-locking capacity is achieved, the pressing handles cannot be opened no matter how large the counter force of the pressed sealing door is, and loosening caused by equipment vibration influences is not likely to happen.

Description

technical field [0001] The invention relates to a locking device for a door, belonging to the technical field of auxiliary devices for mixing equipment. Background technique [0002] Mixing equipment is a mechanical device that uses mechanical force and gravity to uniformly mix two or more materials. During the mixing process, the contact surface area of ​​the material can also be increased to promote chemical reactions and accelerate physical changes. Mixing equipment usually has cleaning doors, inspection doors, etc. to facilitate cleaning or maintenance inside the equipment. The traditional door switch is locked. Composed of swing bolts and star nuts, the purpose of opening and closing the door is achieved through the connection between star nuts and swing bolts. However, this locking device is inconvenient to operate and needs to be disassembled by continuously turning the star nuts. When the time is closed, the connection between the star nut and the swing bolt is easy...
