DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0039] like Figure 1-14 A subway platform protective shield door shown in the figure comprises an upper track 1, a lower track 11, a fixed leaf 12 arranged between the upper track 1 and the lower track 11, and a movable leaf 13 sliding on the upper track 1 and the lower track 11, a receiving groove 14 is provided on the movable leaf 13, a movable door 15 with limited movement is arranged in the receiving groove 14, and the movable leaf 13 and the movable door 15 are connected by a first spring 16;

[0040] The closing process of the shielding door is as follows:

[0041] 1. When the movable leaf 13 moves relatively to close, the movable door 15 comes into contact first;

[0042] 2. After the movable door 15 is closed, the movable leaf 13 can continue to move relatively and drive the first spring 16 to compress until the movable leaf 13 is closed;

[0043] The opening process of the shielding door is as follows:

[0044] 1. The movable fan 13 drives the movable door 15 to open synchronously;

[0045] Second, the movable door 15 stops moving when it is completely moved to the rear side of the fixed leaf 12;

[0046] 3. The movable leaf 13 continues to move after the movable door 15 stops moving, and stops after the elasticity of the first spring 16 is fully released.

[0047] During the closing process of the platform shielding door, the movable door 15 at its upper end is closed synchronously with the subway door. When the subway door is completely closed, the movable door 15 is also closed synchronously, thereby first blocking the passage for passengers to enter and exit the subway through the movable door 15. At this time, the movable fan 13 continues to complete the secondary closing process. Therefore, when a passenger rushes to get on or off the train during the closing process of the platform shielding door, the relatively elastic movable structure between the movable door 15 and the movable fan 13 ensures that even if a passenger is accidentally clamped by the movable door 15, the clamped part or object can be easily pulled out from between the movable doors 15 before the movable fan 13 continues to close for the second time, thereby ensuring that the passenger will not cause personal or property loss, thereby improving the safety of the platform shielding door.

[0048] In one embodiment, a locking groove 2 is provided on the movable door 15, and a locking arm 21 that can move up and down and is adapted to the locking groove 2 is provided on the movable leaf 13; after the locking arm 21 is inserted into the locking groove 2 and moved upward, the movable leaf 13 and the movable door 15 can be locked, and a first groove 3 is provided on the movable leaf 13, one end of the locking arm 21 is located in the first groove 3, and a second spring 31 is provided between the locking arm 21 and the inner wall of the first groove 3, and a top support rotating device located on the side of the locking arm 21 away from the second spring 31 is rotatably provided in the first groove 3. Plate 32; when the top support rotating plate 32 rotates, it can engage and push the locking arm 21 to move upward. A push plate 4 that rotates coaxially with the top support rotating plate 32 is also provided on the top support rotating plate 32. A second groove 41 is provided on the fixed leaf 12, and a fixed push plate 42 is provided in the second groove 41; when the shielding door is normally opened, the top support rotating plate 32 is in a horizontal state, and the push plate 4 is in a vertical state orthogonal to the top support rotating plate 32; when the shielding door is in step two of the closing process, when the movable door 15 moves relatively until it engages, the push plate 4 is pushed by the fixed push plate 42 to rotate to a horizontal state.

[0049] When the shield door is closed, the movable door 15 is first abutted, and the movable leaf 13 will continue to be relatively closed, and the movable door 15 will gradually be stored in the storage groove 14 during the activity closing process. During this process, the first spring 16 will be squeezed and contracted, and the locking arm 21 will be inserted into the locking groove 2. When the movable leaf 13 is about to be completely closed, the fixed push plate 42 will abut against the pushed plate 4, thereby pushing the pushed plate 4 to rotate. During the rotation of the pushed plate 4, the top support rotating plate 32 coaxial with it will be driven to rotate synchronously, thereby making the top support rotating plate 32 abut against the lower surface of the locking arm 21, and push the locking arm 21 to move upward during the continuous rotation until the pushed plate 4 is completely horizontal and the top support rotating plate 32 is completely vertical. At this time, the locking arm 21 is completely engaged with the locking groove 2, thereby locking the movable leaf 13 and the movable door 15, so that they can be pulled back synchronously when opened, thereby not prolonging the door opening time.

[0050] In one embodiment, a fixed frame plate 5 is also provided on the second groove 41, and a third spring 51 is provided on the fixed frame plate 5. A movable frame 52 is provided at one end of the third spring 51 away from the fixed frame plate 5, and a push-down rod 53 that can movably engage with the horizontally pushed plate 4 is provided on the movable frame 52. A movable buckle plate 54 is also provided on the movable frame 52, and a fixed buckle plate 55 is provided on the movable door 15. An arc surface that can engage and slide with each other is provided between the movable buckle plate 54 and the fixed buckle plate 55, and a movable groove 56 for limiting the sliding of the fixed buckle plate 55 is provided on the movable door 13; when the arc surfaces of the movable buckle plate 54 and the fixed buckle plate 55 are in the engaged state, the push-down rod 53 synchronously engages with the pushed plate 4.

[0051] When the shielding door is opened to a certain extent so that the movable door 15 is completely located at the rear side of the fixed leaf 12, it is necessary to ensure that the movable leaf 13 is disengaged from the movable door 15, so that the movable leaf 13 and the movable door 15 return to their initial relative positions, so as to facilitate the relative movement of the movable door 15 and the movable leaf 13 during the subsequent closing process, and then by setting a movable buckle plate 54 on the movable frame 52, when the movable door 15 is about to move completely to the rear side of the fixed leaf 12, the curved surface between the fixed buckle plate 55 on the movable door 15 and the movable buckle plate 54 will abut, and then the movable frame 52 will move downward until the movable door 15 is completely moved to the rear side of the fixed leaf 12, at which time the movable buckle plate 54 is disengaged from the fixed buckle plate 55, and the movable buckle plate 54 rebounds under the action of the third spring 51, so that the movable buckle plate 54 and the movable buckle plate 54 are The back side of the fixed buckle plate 55 is abutted, and then the movable buckle plate 54 is used to buckle the fixed buckle plate 55. When the movable frame 52 moves downward, it will use the downward pushing rod 53 to abut the pushed plate 4 to make it rotate, thereby making the top support rotating plate 32 rotate and disengage from the locking arm 21, so that the locking arm 21 is reset downward under the action of the second spring 31, so that it changes from the locked state in the locking groove 2 to a state that it can be freely withdrawn from the locking groove 2 at any time, thereby releasing the lock between the movable leaf 13 and the movable door 15. At this time, the movable buckle plate 54 is buckled on the fixed buckle plate 55, so that the movable door 15 will no longer pop out and disengage from the receiving groove 14 on the movable leaf 13 under the elastic action of the first spring 16, and can only be pulled apart from the relative position between the movable leaf 13 and the movable leaf 13 by the continued return of the movable leaf 13.

[0052] In one embodiment, a convex plate 6 is further provided on the movable frame 52, and a fixed push block 61 is provided on the movable fan 13. An arc surface that can slide and abut against each other is provided between the convex plate 6 and the fixed push block 61; when the shielding door is normally opened, the arc surface of the convex plate 6 abuts against the fixed push block 61.

[0053] When the shielding door is opened to the step 2 where the movable door 15 stops and the movable fan 13 continues to move back, when the movable fan 13 is about to stop, the curved surface between the fixed push block 61 on the movable fan 13 and the protruding plate 6 will slide in contact with each other, thereby causing the movable frame 52 to move downward. When the movable fan 13 stops completely, the fixed push block 61 and the protruding plate 6 will completely contact with each other, thereby causing the movable buckle plate 54 to be dislocated from the fixed buckle plate 55, thereby releasing the restriction of the movable buckle plate 54 on the movable door 15.

[0054] In one embodiment, a recess 7 is further provided on the movable buckle plate 54 for the fixed push block 61 to move through. Since the fixed push block 61 provided thereon will pass through the position of the movable buckle plate 54 during the backward movement of the movable fan 13, in order to prevent the movable buckle plate 54 from interfering with the movement of the fixed push block 61, a recess 7 is provided on the movable buckle plate 54 so that the fixed push block 61 can move freely through the recess 7.

[0055] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
