In this embodiment, only the lock 10 is used as an example. However, it is not limited thereto, and any lock that can be sensed and fastened when the door panel is closed can be applied. When the second door panel 9 is in a closed position, the lock 10 receives the sensor key 92 and can engage the sensor key 92 to restrict the second door panel 9 to the closed position. Baffle 82 is positionable One of the first door panel 8 and the second door panel 9. In the present embodiment, the baffle 82 is located at the first door panel 8. The baffle 82 is used when the first door panel 8 and the second door panel 9 are simultaneously in the closed position (as shown in FIG. 1C), and the second door panel 9 blocks the shutter 82 to block the first The door panel 8 is moved and the first door panel 8 is constrained to the closed position. Therefore, when both the first door panel 8 and the second door panel 9 are in the closed position, the second door panel 9 is restrained by the lock 10 in the closed position, and the first door panel 8 is also restricted to the closed position by the shutter 82 at the same time. .

Please refer to FIG. 1B to show a top view of a door closing of the double door opening and closing control system of the present invention. Due to the structural design of the door stop device 1 (described in detail below), the push block 91 of the second door panel 9 is blocked by the door stop device 1 and cannot be closed first to enter the closed position. Therefore, only after the first door panel 8 is closed first, and the push block 81 of the door panel 8 enters the door stop device 1 described above, the push block 91 of the door panel 9 can smoothly enter the door stop device 1 to the closed position. At this point, as shown in the first C, the double door panel is closed, and the lock can be locked and operated normally. Since the lock 10 and the second door panel 9 are disposed corresponding to each other, the key 92 of the second door panel 9 can be inserted into the lock 10, and the lock 10 first detects whether the insert 921 on the key 92 is correct.

In addition, the first door panel 8 further has a baffle 82. When the first door panel 8 and the second door panel 9 are both closed and the lock 10 is locked, the first door panel 8 is opened. That is, the first door panel 8 is blocked by the second door panel 9 after the shutter 82 is closed, and the first door panel 8 cannot be opened first without the second door panel 9 being opened first. Therefore, when the lock 10 is in the locked state, the first door panel 8 and the second door panel 9 can be stably closed.

Please refer to FIG. 2A, which is a top plan view showing the simultaneous opening of the two door panels of the double door opening and closing control system according to another embodiment of the present invention. In this embodiment, the second door panel 9 has a baffle 93. When the first door panel 8 and the second door panel 9 are both closed and the lock 10 is locked, the first door panel 8 is opened. A schematic plan view in which the first door panel 8 and the second door panel 9 are simultaneously closed is as shown in FIG.

It can be seen from the above two embodiments that the two door panels, such as the first door panel 8 and the second door panel 9, are configured such that when the two door panels are in the closed position, one of the door panels is pressed by the other door panel, and the other door panel is pressed. A locking mechanism is provided whereby the other door panel can be locked to the door frame when in the closed position.

Please refer to the third figure, which is a door stop device with an outer cover removed according to an embodiment of the invention. Stereogram. The door stop device 1 of the present invention is disposed on a door frame of a machine door (not shown) for controlling the closing sequence of the double door panels of the machine device (for example, the first and second door panels 8, 9 described above). Make sure that one of the door panels reaches the closed position before the other door panel, and the two door panels are safely locked when they are closed in sequence (as shown in Figure 10 of Figure A), and the machine can be started smoothly. . In the embodiment, the door stop device 1 comprises: a body 2, a movable body 3, a reset device, a rod 5 and a guide rail 6. The base body 2 has two positioning slots 21, 22, a first side wall 23 and a second side wall 27, a through hole 24 in the first side wall 23, and a plurality of screw holes 25. The door stop device 1 of the present embodiment is mounted above the door frame and fixed to the door frame by the positioning grooves 21 and 22. The positioning grooves 21 and 22 are adjusted in position and shape according to the position of the arrangement. The reset device of the preferred embodiment is a compression spring 4. In other embodiments, the reset device can also be a tension spring, a torsion spring, a spring, a pneumatic cylinder, and/or a pair of magnets. Subsequent) replaced by one of them.

The movable body 3 in this embodiment is movable in the seat body 2. The movable body 3 has a side surface 34, a recess 31, a blocking portion 32 and a plurality of fixing holes 33. The side surface 34 faces the first side wall 23. The recess 31 has a sloped side surface 311, a bottom surface 312 and an inner wall surface 313. The inclined side surface 311 is adjacent to the side surface 34, and the inner wall surface 313 is adjacent to the blocking portion 32. The bottom surface 312 connects the inclined side surface 311 and the inner wall surface 313.

One end of the compression spring 4 is coupled to the side surface 34, and the other end is coupled to the first side wall 23 to position the movable body at a first position. At this time, the blocking portion 32 abuts against the second side wall 27. That is, the compression spring 4 is in a slightly compressed state to provide a force that pushes rightward against the side 34 of the movable body 3. Thereby, it is possible to ensure that the movable body 3 is fixed at the first position without being subjected to an external force. The rod 5 is disposed in the compression spring 4, and one end of the rod 5 is coupled to the side surface 34, and the other end is inserted into the through hole 24, so that the compression spring 4 can be maintained in the seat body 2 without being elastic due to the compression process. The bomb flies out of the seat 2. The guide rail 6 is fixed in the seat body 2 to guide the movement of the movable body 3.

Please refer to the fourth figure, which is a perspective view of the overall appearance of the door stop device of the present invention, which shows that the door stop device 1 of the present invention further comprises a cover 7 for covering the base 2. The cover body 7 has two through holes 71 and 72 and a plurality of screw holes 73. The size and size of the through holes 71 and 72 are matched with the inserts of the corresponding door plates. When the plurality of screw holes 73 are used to join the lid body 7 and the seat body 2, they are screwed and fixed.

Referring to Figure 5, there is shown an exploded view of a door stop device in accordance with an embodiment of the present invention. Most of the components of the door stop device of the present invention are as shown in the first and second figures. The guide rail 6 The plurality of screw holes 61 are screwed into the base body 2. The movable body 3 is coupled to the plurality of screw holes 64 of the moving members 62, 63 of the guide rail 6 through the plurality of fixing holes 33 by screws, so that the movable body 3 can reciprocate along the guide rail 6. The rod 5 penetrates into the through hole 24 of the seat body 2 and the compression spring 4, and is locked into the screw hole 35 of the movable body 3 by the threaded portion 51, so that the rod 5 can move in synchronization with the movable body 3 and move in the same direction.

Referring to the sixth drawing, it is shown that an inner wall of the recess 31 of the door stop device of the present invention is a smooth inclined side surface 311.

Please refer to the seventh drawing, which shows a top view of the movable body of the door stop device of the present invention which has not been displaced. The push blocks 81, 91 in the figure are respectively located on a first door panel 8 and a second door panel 9 of the double door panel, and move along with the rotation of the first door panel 8 and the second door panel 9. When the first door panel 8 and the second door panel 9 are rotated to the closed position, the through holes 71, 72 are respectively disposed on the moving paths corresponding to the push blocks 81, 91, and the through holes 71 are directly opposite to the recess 31. The inclined side surface 311 and the through hole 72 are opposite to the blocking portion 32. At this time, the push blocks 81 and 91 of the double door panel of the present invention also correspond to the positions of the groove 31 and the stopper 32, respectively. Therefore, the through hole 72 is closed by the stopper 32, so that the push block 91 of the second door panel 9 cannot be inserted into the through hole 72; that is, the second door panel 9 cannot be completely closed. The through hole 71 allows the push block 81 of the corresponding door panel to push against the inclined side surface 311 to enter. The guide rail 6 can guide the movable body 3 to move between a first position A and a second position B (see the sixth figure). When the movable body is located at the first position A, the blocking portion 32 of the movable body 3 abuts against the second side wall 27 of the seat body 2, and the blocking portion 32 is located in a space 26 (see the sixth figure) and the double door The push blocks 81, 91 of the door panel correspond to the position of the inclined side surface 311 and the stop portion 32. That is, when the movable body 3 is located at the first position A, the two through holes 71, 72 respectively correspond to the positions of the push blocks 81, 91.

Referring to the eighth embodiment, in the embodiment, the double door panels corresponding to the through holes 71 are pushed against the inclined side surface 311 by using the push block 81 to move the movable body 3 toward the compression spring 4 . Displacement. When the push block 81 touches the bottom surface 312, the movable body 3 is located at the second position B, and the push blocks 81, 91 of the double door panel respectively correspond to the bottom surface 312 and the space 26, and the compression spring 4 is further compressed. In order to accumulate an elastic force, the elastic force is used to restore the movable body 3 to the first position A. At this time, the rod 5 is displaced with the movable body 3 and protrudes through the first side wall 23 of the seat body 2. However, it should be noted that since the compression spring 4 has a certain elastic force against the deformation, the movable body 3 is moved in the direction of the compression spring 4, so that the compression spring 4 is generally short or less. When the slight thrust is pushed against the inclined side surface 311, the first door panel 8 cannot be closed due to the reverse elastic force of the compression spring 4. For example, the force of the wind blown door panel does not allow the movable body 3 to generate sufficient displacement to open the through hole 72. Also, due to the reverse elastic force of the compression spring 4, after the push blocks 81, 91 are separated from the movable body 3, the movable body 3 position is returned from the second position B to the first position A.

Please refer to the ninth figure, which illustrates a schematic view of the present invention after the two-door two-door panel is simultaneously closed. In this embodiment, a lock (not shown) coupled to the present invention is coupled to the door frame of the machine equipped with the push block 91. Therefore, only the push block 81 is sequentially pushed along with the first door 8 The inclined side surface 311 of the movable body 3 is formed to create the space 26. Then, after the second door panel 9 is pushed into the space 26, the lock can be smoothly locked and the machine can operate smoothly.

In summary, the movable body 3 blocks the second door panel 9 in the first position so that the second door panel 9 cannot reach the closed position, and when the first door panel 8 is moved to the closed position, the movable body has been subjected to the first position. The movement of the door panel 8 affects the second position that no longer blocks the second door panel 9 so that the second door panel 9 can be moved to the closed position.

In summary, the double door opening and closing control system of the present invention is designed with a special structure, except that the door panel of the machine unit can be prevented from being mistakenly closed, and the procedure for closing the door panel must be sequentially closed. Then, by the function of sensing, locking and fastening the door panel of a single lock, and the mechanism of the baffle, the single lock jams a door panel, and the door panel blocks the other door panel, so that the double door panel can be stably closed at the same time, and The machine can be started safely and safely. Therefore, the double door opening and closing control system provided by the invention can effectively ensure the cleanliness inside the machine and the safety of the personnel maintenance operation.
