Description

Technical Field

[0001] The utility model relates to the technical field of sterilizers, in particular to a sterilizer door lock mechanism. Background Art

[0002] The sterilizer is one of the main sterilization equipment in the medicine and pharmaceutical industry. It occupies an important production position in the medicine and pharmaceutical industry. Its main working principle is to pass high-pressure steam into the sterilizer to achieve the sterilization effect. It is widely used in medical and pharmaceutical fields. A door body is set on the sterilizer. When the door body is closed, the door lock is manually moved to prevent the door body from opening. The door body can only be opened after the door lock is opened. The door lock of the sterilizer generally includes a lock core and a limit plate. The limit plate is fixedly connected to the sterilizer. A horizontal limit hole is set on the limit plate, and the lock core is horizontally connected to the door body in the left and right directions. A ball head is set on the lock core. The lock core moves by moving the ball head. The ball head moves horizontally and vertically as a whole. Generally, the horizontal movement first drives the lock core to move horizontally, and then moves horizontally and vertically along the waist-shaped hole at the same time. The vertical movement causes the lock core to rotate, so that the lock core is locked in the limit hole. Most of the current sterilizer door lock mechanisms directly control the movement of the ball head to achieve unlocking or locking. The operation form is single and cannot meet the needs of different users for different opening and locking methods, and users lack room for choice. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a sterilizer door lock mechanism to solve the technical problem that the operation mode of opening and closing the sterilizer door lock in the prior art is relatively single.

[0004] In order to solve the above technical problems, the utility model provides a sterilizer door lock mechanism, including a sterilizer body, a door body, a limit plate and a lock core, the door body is hinged on the sterilizer body, the limit plate is connected to the sterilizer body, the limit plate is provided with a limit hole, the lock core is movably connected to the door body along the left and right directions, the lock core is connected to a ball head, and the lock core enters or exits the limit hole by moving the ball head, wherein, it also includes a rotating plate, one end of the rotating plate is rotatably connected to the door body and the rotation axis is arranged along the front and rear direction, the rotating plate is connected to a driving assembly, a vertically arranged guide long hole is provided in the middle of the rotating plate, the ball head is located in the guide long hole and on the moving path of the inner wall of the guide long hole, and the rotating plate is rotated by moving or rotating the driving assembly.

[0005] After adopting the above structure, the sterilizer door lock mechanism of the utility model has the following advantages: a rotating plate is added on the basis of the prior art, and the rotating plate is driven to rotate by the driving assembly. When the rotating plate rotates, since the ball head is located in the guide long hole, at the beginning of the rotation of the rotating plate, since the longitudinal length of the guide long hole is greater than the transverse width, the side wall of the guide long hole first abuts against the ball head and drives the ball head to move horizontally. Since there is a gap in the longitudinal direction between the ball head and the guide long hole at this time, no longitudinal movement occurs. After the rotating plate rotates a certain angle, the guide long hole will cause the ball head to move horizontally and vertically at the same time, which is the same as the movement state of the ball head driving the lock core to enter the limiting hole in the prior art, so the lock core can enter or exit the limiting hole through the driving assembly; therefore, after the rotating plate is set, as long as the structure of the driving assembly is changed, unlocking and locking in different ways can be achieved, and sterilizers with different unlocking methods can be produced. Users have room for choice and can choose a more suitable sterilizer according to their own preferences.

[0006] As an improvement, the sterilizer body is connected to a magnetic switch and the rotating plate is connected to a magnet. When the lock core enters the limit hole, the magnet corresponds to the position of the magnetic switch. With this structure, when the lock core enters the limit hole, the magnet causes the magnetic switch to close and outputs a signal indicating that the door lock is closed, which is used in conjunction with other control programs of the sterilizer.

[0007] As an improvement, a groove is provided on the side wall of the door body, and an avoidance groove is provided on the side wall of the groove. The other end of the rotating plate passes through the avoidance groove and is located in the groove. The driving assembly includes a handle, which is connected to the other end of the rotating plate. The rotating plate is rotated by turning the handle. This structure has the advantages of simple structure and easy operation.

[0009] As an improvement, the driving assembly includes a connecting rod and a knob, the knob is rotatably connected to the front end face of the door body, one end of the connecting rod is hinged to the middle part of the rotating plate, and the other end of the connecting rod is hinged to the knob. The rotation axis of the connecting rod and the knob is off-axis with the rotation axis of the knob and the door body, and the rotating plate is rotated by rotating the knob. This structure has the advantages of simple structure and easy operation.

[0010] As an improvement, the driving assembly includes a dial knob, a connecting piece and a connecting column. The other end of the rotating plate is connected to a connecting column extending forward. A first through groove is provided on the connecting piece in the left and right directions. The front end of the connecting column is slidably connected in the first through groove. The dial knob is vertically slidably connected to the front end surface of the door body. The dial knob is connected to the front end of the connecting piece. The rotating plate is rotated by vertically moving the dial knob. This structure has the advantages of simple structure and easy operation.

[0011] As an improvement, the drive assembly also includes a guide plate, a limit column and a guide block. The guide plate is vertically connected to the door body, a second through groove is vertically provided on the upper edge of the guide plate, the rear end face of the dial knob is connected to the limit column, the limit column is connected to the connecting piece, the limit column is connected to the guide block, and the guide block is slidably connected in the second through groove. By adopting this structure, the stability of the vertical movement of the dial knob and the connecting piece is improved by setting the guide block and the guide plate.

[0012] As an improvement, the rotating plate includes a connecting plate and a connecting rod, one end of the connecting plate is rotatably connected to the door body, and the other end of the connecting plate is connected to one end of the connecting rod. The connecting rod is connected to a driving assembly, and a long guide hole is provided on the connecting plate. With this structure, the driving assembly has a larger installation space on the connecting rod side, and it is more labor-saving when moving or rotating the driving assembly.
