Description

Technical Field

[0001] This utility model relates to the field of rail transit platform screen doors, specifically to a three-section door locking mechanism. Background Technology

[0002] With the rapid development of rail transit construction, the construction of high-speed rail, subway, and urban transportation hubs has led to an increasing demand for various types of trains entering stations. The technology of platform screen doors also needs to develop accordingly. Different train models require different opening degrees and positions of the doors, and the screen doors also need to be constructed to accommodate different opening degrees and positions. The research and development of three-panel screen doors is a response to this need. The opening method of the three-panel doors is determined by the needs of the train models entering the station and needs to be continuously combined. When the two doors on the left need to be integrated, they need to be locked together. When the two doors on the right need to be integrated, they need to be locked together. When the train leaves the station, all three doors need to be locked together. Under this requirement, a three-door locking mechanism was developed. Utility Model Content

Detailed Implementation

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] like Figure 1 As shown, this specific embodiment is a three-section sliding door and two sets of locking mechanisms between the three door panels that cooperate with the three-section sliding door. One locking mechanism is divided into a latch part including a fixed base 1 and a lock block seat 2, and a lock hook part including an automatic base 3 and a rotating locking shaft 5. The latch part is installed on the left and right door panels of the three-section sliding door and cooperates with the lock hook parts on the left and right sides of the middle door panel. When the two left door panels need to be integrated, the middle door panel and the left door panel are connected and fixed into a whole by the left locking mechanism, or when the two right door panels need to be integrated, the middle door panel and the right door panel are connected and fixed into a whole by the right locking mechanism.

[0031] like Figure 2-10As shown, this is the structure of a single locking mechanism, wherein the fixed base 1 is fixedly installed on the side door panel of the three-section sliding door and is adjacent to the middle door panel, and the automatic base 3 is fixedly installed on the middle door panel of the three-section sliding door and is located behind the fixed base 1 on the corresponding side.

[0032] A locking block seat 2 is fixedly installed on the fixed base 1, which is regarded as the locking tongue in the locking structure. A bearing seat 4 is fixedly installed on the automatic base 3. A rotating locking shaft 5 is spun on the bearing seat 4 through the bearing. A wedge-shaped structure is integrally formed on the rotating locking shaft 5, which is regarded as the locking hook in the locking structure. At the same time, a stop block structure is integrally formed on the bearing seat 4. That is, when the locking block seat 2 and the rotating locking shaft 5 are engaged and locked, the stop block structure abuts against the locking block seat 2, thereby realizing the locking between the fixed base 1 and the automatic base 3.

[0033] An electromagnet unit 6 is fixedly mounted on the automatic base 3. The movable end of the electromagnet unit 6 is a slide rod structure with a return spring. When the electromagnet unit 6 is not working, the slide rod extends downwards due to its own weight and the combined action of the return spring. When the electromagnet unit 6 is working, it pulls the slide rod upwards. An electromagnet unlocking shaft 7 is fixedly mounted on the slide rod of the electromagnet unit 6. An unlocking shaft protective sleeve 8 is screwed onto the electromagnet unlocking shaft 7 via a bearing. A guide rail 9 is fixedly mounted on the automatic base 3, and the guide rail 9 is located below the electromagnet unit 6. A switch trigger plate 10 is mounted on the guide rail 9. The unlocking shaft protective sleeve 8 is screwed onto the upper end of the switch trigger plate 10 via a bearing. Two micro switches 11 arranged vertically are fixed on the automatic base 3. The button end of the micro switch 11 is configured to cooperate with the switch trigger plate 10. When the electromagnet unit 6 is not working, the switch trigger plate 10 moves to the lower end and triggers the lower micro switch 11 to indicate the closed state. When the electromagnet unit 6 is working, the switch trigger plate 10 moves to the upper end and triggers the upper micro switch 11 to indicate the open state.

[0034] A reversing shaft 13 is fixedly mounted on the automatic base 3. An automatic reversing plate 14 is spun onto the reversing shaft 13 via bearings. Both ends of the automatic reversing plate 14 are provided with oblong holes. A lever shaft 15 is spun onto the arm of the rotating locking shaft 5 via bearings. The lever shaft 15 is movably inserted into the oblong hole at the left end of the automatic reversing plate 14. A slide rail shaft 12 is fixedly mounted on the lower end of the switch trigger plate 10. The slide rail shaft 12 is movably inserted into the oblong hole at the right end of the automatic reversing plate 14.

[0035] When using this device, if the electromagnet unit 6 is not working, the electromagnet unlocking shaft 7 moves downward, pushing the switch trigger plate 10 to the lower position. At this time, the micro switch 11 on the lower side is triggered to indicate locking. The switch trigger plate 10 then pushes the automatic reversing plate 14 to rotate clockwise via the slide rail shaft 12. The automatic reversing plate 14 then drives the rotary locking shaft 5 to rotate counterclockwise via the lever shaft 15, thus locking the device. When the corresponding lock block seat 2 hooks with the rotary locking shaft 5, it cannot be unlocked, thus achieving a triple push. When the connection between the two door panels of the sliding door is locked, but the corresponding lock block seat 2 and the rotating locking shaft 5 are not hooked, as the two door panels close, the lock block seat 2 pushes the wedge structure on the rotating locking shaft 5, causing the rotating locking shaft 5 to rotate clockwise. At this time, the slide rod of the electromagnet unit 6 is passively raised, and after the lock block seat 2 passes the rotating locking shaft 5, the rotating locking shaft 5 rotates counterclockwise to reset, thus completing the locking between the lock block seat 2 and the rotating locking shaft 5, that is, the locking between the two door panels that were not originally connected;

[0036] When the electromagnet unit 6 is working, the switch trigger plate 10 moves to the upper position, and the rotating locking shaft 5 rotates clockwise to the unlocked state and maintains this state. At this time, the lock block seat 2 can move freely and cannot hook with the rotating locking shaft 5, thus realizing the free opening and closing between the two door panels of the three-section sliding door.

[0037] Compared with the prior art, the beneficial effects of this utility model are:

[0038] 1. This device is equipped with a three-section sliding door, which allows for the selection of two door panels to be combined according to the different vehicles arriving at the platform, enabling the door to be opened from different positions. Furthermore, a James Lock structure is installed to achieve combination locking between two adjacent door panels, that is, to lock two door panels as a whole.

[0039] 2. This device realizes the transmission connection between the electromagnet unit 6 and the rotary locking shaft 5 through the switch trigger plate 10 and the automatic reversing plate 14, realizes the automatic control of the opening and closing state of the rotary locking shaft 5, and sets two micro switches 11 based on the switch trigger plate 10, so that the corresponding micro switch 11 is triggered according to the upper or lower position of the switch trigger plate 10 to display the open or closed state of the lock.

[0040] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
