At the rear end of the body of the upper and lower clamping blocks 150 and 151 and the left and right clamping blocks 152 and 153 are formed curved guide grooves 112a and 122a formed on the upper and lower cams 112 and 122 and the left and right cams 132 and 142, The upper and lower shafts 110 and 120 and the upper and lower cams 112 and 122 and the left and right shafts 130 and 140 are provided with guide pins 150a, 151a, 152a, and 153a, The guide pins 150a, 151a, 152a and 153a are moved forward and backward along the guide grooves 112a, 122a, 132a and 142a of the left and right cams 132 and 142. Thus, the upper and lower clamping blocks 150 and 151 and the left and right clamping The blocks 152 and 153 can protrude and retreat in the direction of the inlet 12 of the chamber housing 10. [

The upper and lower clamping blocks 150 and 151 and the left and right clamping blocks 152 and 153 are installed on the front surface of the support frame 14 installed along the rim of the inlet 12 of the chamber housing 10, A guide cover 15 for preventing detachment in the direction of the entrance 12 of the main body 1 is provided.

The control means 30 controls the driving means 102 to rotate the shaft of either of the upper and lower shafts 110 and 120 and the left and right shafts 130 and 140 to be interlocked with the bevel gears 160 and 162 All the shafts rotate equally.

In this case, a driven gear 104 is integrally provided on the upper side of the right shaft 140 and engaged with the driving gear 102b of the motor 102a as the driving means 102 as shown in the figure. Of course, the motor 102a uses a well-known motor that is capable of forward rotation and reverse rotation control and includes a reduction gear unit for reducing the rotation speed.

When the motor 102a is rotated in one direction, the upper and lower clamping blocks 150 and 151 and the left and right clamping blocks 152 and 153 are connected to the inlet 12 of the chamber housing 10, It is impossible to open the door 20 by clamping the four corners of the door 20 so that the motor 102a can not open the upper and lower clamping blocks 150 and 151 and the left and right clamping blocks 150 and 151. [ The door 20 can be opened when the doors 152 and 153 are retracted from the inlet 12 of the chamber housing 10. [

One side of the door 20 is rotatably hinged to the right shaft 140 and a torsion spring 170 is provided between the door 20 and the chamber housing 10 to rotate the door 20, An elastic restoring force is applied in a direction in which the inlet 12 of the chamber housing 10 is closed.

Of course, the door 20 may be hinged to the left shaft 130, and the change of the simple design position is naturally also within the scope of the present invention.

In order to allow the door 20 to be automatically opened by the control of the control means 30 when the door is opened, the right shaft 140 is provided with a latching member And a retaining block 145 protruding from the outer circumferential surface of the retaining block 145. [ More specifically, the pulling block 180 is configured such that a pulling jaw 182 protrudes from one side of the outer circumferential surface of the body 181 having a disk shape so that the right shaft 140 rotates in the other direction The end of the latching member 22 provided on the lower door 20 is hooked on the pulling jaw 182 of the pulling block 180 to overcome the elastic restoring force of the torsion spring 170 and forcibly open the door 20. [

Of course, when the driving of the motor 102a is stopped again after the door 20 is opened, the door 20 is automatically closed by the elastic restoring force of the torsion spring 170. [

A pulling bar 190 having a hinge pin 192 protruding from one side thereof and having a guide pin 194 on the other side thereof so as to be rotatable in a front edge direction of the door 20, And a driving disc 196 having a spiral guide groove 196a for guiding a guide pin 194 of the pulling bar 190 is formed on the upper shaft 110. [

According to this structure, the door 20 is automatically closed by the elastic restoring force of the torsion spring 170, so that the upper and lower shafts 110 and 120 and the left and right shafts 130 and 140 are rotated in one direction in the range of 90 to 120 ° The driving disc 194 rotates together and rotates toward the upper front of the door 20 first. When the motor 102a is driven, the upper and lower shafts 110 and 120 and the left and right shafts 130 and 140 are rotated in one direction so that the guide pin 194 moves along the helical guide groove 196a, The pulling bar 190 presses the upper end of the front surface of the door 20 and makes the door 20 more closely contact the inlet 10 of the chamber housing 10. Even if the upper shaft 110 further rotates, the relative distance between the outer circumferential surface of the driving disk 196 and the center thereof is constant, and the pulling bar 190 is no longer rotated.

On the other hand, if a failure occurs in the control means 30 or the motor 102a, the door must be forcibly opened. To this end, the lower shaft 120 is integrally provided with a release disk 198 having a plurality of tool grooves 198a formed along the outer circumferential surface thereof. The upper and lower clamping blocks 150 and 151 and the left and right clamping blocks 152 and 153 and the pulling bar 190 are rotated by rotating the lower shaft 120 by inserting the end of the tool such as a screwdriver or a wrench into the tool groove 198a, Can be released.

The door clamping apparatus according to the present invention can be widely applied to doors of large-sized sterilization machines of high temperature and high pressure as well as ordinary medical chemistry and general chambers used for low temperature and low pressure requiring sealing.

Hereinafter, an operation example of a door clamping apparatus for a chamber according to the present invention will be described with reference to FIGS. 3 to 9. FIG.

The pulling bar 190 rotates to the top of the front surface of the door 20 while the door 20 is rotated by the elastic restoring force of the torsion spring 170 to the inlet 12 of the chamber housing 10.

When the motor 102a is operated by the control means 30 to rotate the upper and lower shafts 110 and 120 and the left and right shafts 130 and 140 in one direction, So that the door 20 is further brought into close contact with the inlet 12 of the chamber housing 10. When the upper and lower shafts 110 and 120 and the left and right shafts 130 and 140 are continuously rotated in one direction, the upper and lower clamping blocks 150 and 151 and the left and right clamping blocks 152 and 153 are inserted into the inlet 12 of the chamber housing 10 So that the edges of the door 20 are uniformly clamped to be completely close to each other and the door 20 is prevented from being opened even if the pressure inside the chamber housing 10 rises.

For example, when the door is to be opened after sterilizing a medical device or clothes, the motor 102a is operated by driving the control means 30 to rotate the upper and lower shafts 110 and 120 and the left and right shafts 110 and 120. [ The upper and lower clamping blocks 150 and 151 and the left and right clamping blocks 152 and 153 are retracted from the entrance 12 of the chamber housing 10 and are out of the door rim and the pulling bar 190 The door 20 rotates and moves upward so that the door 20 can be opened.

When the door 20 is to be opened, the upper and lower shafts 110 and 120 and the left and right shafts 130 and 140 continue to rotate in the other direction by operating the motor 102a by driving the control means 30 The pulling jaw 182 of the pulling block 180 of the rotating right shaft 140 pulls the latching member 22 provided on the door 20 to forcibly open the door 20. [

The door 20 is automatically closed by the resilient restoring force of the torsion spring 170 when the control means stops driving the motor 102a after removing the sterilized medical device or clothes.

Such a configuration may include a plurality of sensing means for sensing the rotation angle of the upper and lower shafts 110 and 120 and the left and right shafts 130 and 140 and sensing the opening and closing of the door. Can be applied.
