Abstract
The invention discloses a safety locking device of a pneumatic lifting door used in a sterilization cabinet, which comprises a base bracket and a cabinet body arranged on the base bracket, wherein a cabinet body flange is arranged on the cabinet body, a door fixing hook is arranged on the cabinet body flange, a door body is movably arranged between the door fixing hook and the cabinet body flange, a large cylinder is fixedly arranged on the door body, a piston rod of the large cylinder is fixedly connected with the base bracket, the bottoms of two sides of the cabinet body flange are respectively fixedly provided with a small cylinder, a piston rod of the small cylinder is connected with a positioning column, and the positioning column is arranged below the closed door body after extending outside. The safety locking device of the pneumatic lifting door, adopting the structure, is used for locking the door body by adopting a pair of positioning columns symmetrically, and has the advantages of high locking strength because the door body can not generate left and right shaking after being locked, large supporting strength on the door body, simple structure, and convenience for installation and maintenance.
Description
Technical field
The present invention relates to the safe locking device of employed Pneumatic elevation door in a kind of cabinet of sterilizing.
Background technology
The safe locking device of employed Pneumatic elevation door comprises in the sterilization cabinet at present: base support, be arranged on the cabinet on the base support, and cabinet is provided with the cabinet flange; The cabinet flange is provided with a stay hook; The door body is movably arranged between a stay hook and cabinet flange, and big cylinder is fixedly installed on the body, and the piston rod of big cylinder is fixedly connected with base support; Centre position, bottom at the cabinet flange is provided with little cylinder, and little cylinder is connected with gripper shoe through transmission mechanism.
During work; The door body moves up and down between cabinet flange and door stay hook: at closing time; Big cylinder promotes a door body and moves up, and when arriving the fastening position of door body, big cylinder stops to move concurrent going out and closes the signal that puts in place; The little cylinder of cabinet flange bottom promotes gripper shoe through transmission mechanism then, and locking is supported in the bottom that makes gripper shoe arrive the door body; When opening the door; The little cylinder of cabinet flange bottom is removed the support locking of opposite house body through transmission mechanism pulling gripper shoe, and big then cylinder pulling door body moves down; When making a body arrive completely the enable possition, big cylinder stops to move concurrent going out and reaches the signal of position.
The major defect that the safe locking device of the Pneumatic elevation door of said structure exists is: because the middle part of an opposite house body is supported, door is known from experience the generation double swerve; The strength ratio of gripper shoe is lower, in the transportation of equipment, can't support by the opposite house body; Support the connection complex structure of locking, reliability is low.
Summary of the invention
The technical problem that the present invention will solve is: a kind of safe locking device that support strength is big, the door body can not produce the Pneumatic elevation door of double swerve after locking of locking intensity height, opposite house body is provided.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the safe locking device of Pneumatic elevation door comprises: base support; Be arranged on the cabinet on the base support, cabinet is provided with the cabinet flange, and the cabinet flange is provided with a stay hook; The door body is movably arranged between a stay hook and cabinet flange; Big cylinder is fixedly installed on the body, and the piston rod of big cylinder is fixedly connected with base support, and be characterized in: the bottom position in cabinet flange both sides is set with little cylinder respectively; The piston rod of little cylinder is connected with reference column, is positioned at the below of the door body of closing after reference column stretches out.
The further technical scheme of the present invention is: the bottom position in cabinet flange both sides is set with fixed cover respectively, and little cylinder is fixedly mounted on the fixed cover, and reference column is movably arranged in the fixed cover.
Advantage of the present invention is: adopt a pair of reference column symmetry locking door body, the door body can not produce double swerve after locking, and locking intensity support strength high, the opposite house body is big, and simple in structure, convenient for installation and maintenance.

Fig. 6 is the little cylinder shown in Figure 3 and the mounting structure enlarged detail of reference column.
The specific embodiment
Referring to Fig. 1 to Fig. 6, the safe locking device of Pneumatic elevation door of the present invention comprises: base support 7; Be arranged on the cabinet 1 on the base support 7, cabinet 1 is provided with cabinet flange 2, and cabinet flange 2 is provided with a stay hook 3; Door body 5 is movably arranged on 2 of a stay hook 3 and cabinet flanges; Big cylinder 9 is fixedly installed on the body 5, and the piston rod of big cylinder 9 is fixedly connected with base support 7, and the bottom position in cabinet flange 2 both sides is set with stingy cylinder 4 respectively; The piston rod of stingy cylinder 4 is connected with reference column 8, is positioned at the below of the door body 5 of closing after reference column 8 stretches out.Bottom position in cabinet flange 2 both sides in the present embodiment is set with fixed cover 6 respectively, and stingy cylinder 4 is fixedly mounted on the fixed cover 6, and reference column 8 is movably arranged in the fixed cover 6.
During work; Door body 5 moves up and down at cabinet flange 2 and 3 of stay hooks of door: at closing time, big cylinder 9 promotes door body 5 and moves up, when arriving the fastening position of door body 5; Big cylinder 9 stops to move concurrent going out and closes the signal that puts in place; The stingy cylinder 4 that is fixed on then on the fixed cover 6 begins action, and the reference column 8 that promotion is connected with the piston rod of stingy cylinder 4 is protruding, arrives locked position and also sends signal; When opening the door, be fixed on stingy cylinder 4 on the fixed cover 6 when receiving enabling signal, stingy cylinder 4 begins action; The reference column 8 that pulling is connected with the piston rod of stingy cylinder 4 is withdrawn inwards; Reference column 8 is regained in the fixed cover 6, removed the locking of opposite house body 5 and send signal, big then cylinder 9 pulling door bodies 5 move down; When making a body 5 arrive completely the enable possition, big cylinder 9 stops to move concurrent going out and reaches the signal of position.
Adopt a pair of reference column 8 symmetry locking door bodies 5, door body 5 can not produce double swerve after locking, and locking intensity support strength high, opposite house body 5 is big, and simple in structure, convenient for installation and maintenance.
