Abstract
The utility model discloses a safety locking device of a pneumatic overhead door used in a sterilization cabinet. The safety locking device comprises a base support and a cabinet body arranged on the base support; 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 support; small cylinders are respectively fixedly arranged at the bottoms of the two sides of the cabinet body flange; piston rods of the small cylinders are connected with positioning columns; and after extending out of the cabinet body flange, the positioning columns are positioned below the closed door body. The safety locking device of the pneumatic overhead door adopting the structure adopts a pair of positioning columns to symmetrically lock the door body, so that the door body cannot sway left and right after being locked, the locking strength is high, and the support strength over the door body is high; and additionally, the safety locking device has a simple structure and is convenient to mount and maintain.
Description
Technical field
This utility model 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, cabinet is provided with the cabinet flange, the cabinet flange is provided with a fixation hook, the door body is movably arranged between a fixation hook and cabinet flange, and big cylinder is fixedly installed on the body, and the piston rod of big cylinder is fixedlyed connected with base support, centre position, bottom at the cabinet flange is provided with little cylinder, and little cylinder is connected with gripper shoe by drive mechanism.
During work, the door body moves up and down between cabinet flange and door fixation hook: at closing time, big cylinder promotes the door body and moves up, when arriving the closed 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 by drive 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 spurs gripper shoe by drive mechanism, removes the support locking of opposite house body, 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, can't support by the opposite house body in the transportation of equipment; Support the complex structure that is connected and installed of locking, reliability is low.
The utility model content
The technical problems to be solved in the utility model 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 solution adopted in the utility model is: the safe locking device of Pneumatic elevation door, comprise: base support, be arranged on the cabinet on the base support, cabinet is provided with the cabinet flange, the cabinet flange is provided with a fixation hook, the door body is movably arranged between a fixation hook and cabinet flange, big cylinder is fixedly installed on the body, the piston rod of big cylinder is fixedlyed connected with base support, be characterized in: the bottom position in cabinet flange both sides is set with little cylinder respectively, and 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 this utility model 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.
The utility model has the advantages that: adopt a pair of reference column symmetry locking door body, the door body can not produce double swerve after locking, and the support strength of locking intensity height, opposite house body is big, and simple in structure, convenient for installation and maintenance.

Fig. 5 is the left TV structure sketch map of door opening state shown in Figure 1.
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 described in the utility model, comprise: base support 7, be arranged on the cabinet 1 on the base support 7, cabinet 1 is provided with cabinet flange 2, cabinet flange 2 is provided with a fixation hook 3, door body 5 is movably arranged on 2 of a fixation hook 3 and cabinet flanges, big cylinder 9 is fixedly installed on the body 5, the piston rod of big cylinder 9 is fixedlyed connected with base support 7, bottom position in cabinet flange 2 both sides is set with stingy cylinder 4 respectively, and 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 fixation hooks of door: at closing time, big cylinder 9 promotes door body 5 and moves up, when arriving the closed 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 the support strength of locking intensity height, opposite house body 5 is big, and simple in structure, convenient for installation and maintenance.
