Abstract
The utility model relates to a central door lock structure for vacuum freeze drying machines. The utility model is mainly composed of a gear, racks, a linking rod, a lock bolt, a lock catch, etc., wherein, the gear is arranged in the middle in a box door; a plurality of racks are arranged along the tangential direction of the gear; the rack and the gear are mutually engaged; the racks are connected with the linking rod along the clockwise direction of the gear; the other end of the linking rod is connected with the lock bolt; the circumference of a box doorway corresponding to the lock bolt is provided with the lock catch; a handle which is axially bonded to the gear is arranged out of the box door. The utility model is the central door lock structure for vacuum freeze drying machines, having the advantages of simple structure and convenient operation.
Description
The utility model relates to a kind of vacuum freeze drier central door lock structure.
The freeze-drying tank gate of conventional vacuum lyophilizer safe locking when moise-heat sterilization is to bear the immense pressure from steam.Usually the chamber door of freeze dryer adopts many cover handwheel locking modes, complicated operation.
It is a kind of simple in structure that the purpose of this utility model is to provide, the vacuum freeze drier central door lock structure of being convenient to operate.
For achieving the above object, the utility model is taked following design proposal: this vacuum freeze drier central door lock structure, mainly form by gear, tooth bar, continuous motion stem, dead bolt, snap close etc., described gear is installed on the centre in the chamber door, tangent direction along described gear is provided with several tooth bars, described rack and pinion is meshing with each other, described tooth bar connects continuous motion stem along the clockwise direction of described gear, the other end of described continuous motion stem connects dead bolt, and snap close is installed at corresponding described dead bolt place around the chamber door mouth; Install handle outside chamber door, described handle and described gear are coupling.Described dead bolt is a wedge shape.
Because the utility model adopts above technological scheme, when needing moise-heat sterilization, handle with sleeve, the wheel and rack gear motion that links to each other with handle, tooth bar inserts dead bolt in the snap close on freeze-drying tank doorway by continuous motion stem, and the gate is locked.Therefore, the utility model is simple in structure, is convenient to operation.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model one embodiment's schematic representation
As shown in Figure 1, this vacuum freeze drier central door lock of the utility model structure, mainly form by gear 5, tooth bar 4, continuous motion stem 1, dead bolt 2, snap close 3 etc., described gear 5 is installed on the centre in the chamber door 7, tangent direction along described gear 5 is provided with several tooth bars 4, described tooth bar 4 is meshing with each other with gear 5, described tooth bar 4 connects described continuous motion stem 1 along the clockwise direction of described gear 5, the other end of described continuous motion stem 1 connects dead bolt 2, and snap close 3 is installed at corresponding described dead bolt 2 places around chamber door frame 8; Device handle 6 outside chamber door 7, described handle 6 is coupling with described gear 5.Described dead bolt 2 is a wedge shape.
When needing moise-heat sterilization, handle with sleeve 6, the gear 5 and tooth bar 4 gear motions that link to each other with handle 6, with in the snap close 3 on the dead bolt 2 insertion freeze-drying tank doorframes 8, chamber door 7 is promptly locked by continuous motion stem 1 for tooth bar 4.
Below only be an embodiment of the present utility model, any based on equivalents of the present utility model all within protection domain of the present utility model.
