Description

Technical Field

[0001] This utility model relates to the field of platform screen door technology, specifically to a subway platform screen door that can be opened in an emergency. Background Technology

[0002] With the rapid development of urban rail transit, subway platform screen doors have become a key facility for ensuring passenger safety and improving operational efficiency. Traditional screen door systems usually adopt a fixed design or an electric sliding door structure, and their opening and closing mainly rely on the instructions of the central control system. Under normal operating conditions, they can effectively isolate the track area from the waiting area.

[0003] In the event of an emergency, the existing platform screen doors need to wait for the central control room to issue an unlocking command or be manually operated by staff to open. However, the response time for the central control room to issue an unlocking command often exceeds 30 seconds. Therefore, when opening the platform screen doors in an emergency, it is necessary to wait for the central control room to issue an unlocking command, which delays the efficiency of emergency opening of the platform screen doors. Utility Model Content

[0004] The purpose of this invention is to provide a subway platform screen door that can be opened in an emergency, in order to solve the problems raised in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an emergency-openable subway platform screen door, comprising:

[0006] Shielding walls are used to fix the subway platform;

[0007] The slide rail has a notch in the shielding wall, and the slide rail is fixedly installed on one side of the shielding wall and below the notch;

[0008] There are two sliders, which are symmetrically slidably installed on the top of the slide rail. A shielding door is fixedly installed on the top of the slider. When the two sliders are close to each other on one side, the two shielding doors are also close to each other on the other side, and the gap is sealed.

[0009] The sliding block has a groove on the side of the slide rail away from the shielding wall. There are two sliding blocks, which are symmetrically slidably installed in the groove. The slide rail is equipped with a driving mechanism that is connected to both sliding blocks. It is used to make the two sliding blocks slide in opposite directions or stop sliding. A fixing plate is fixedly installed on both sliding blocks and on the outside of the slide rail.

[0010] The snap-fit ​​component is mounted on the fixed plate. A cavity is provided inside the shielding door. A slot communicating with the cavity is provided at the bottom of the shielding door on the side away from the shielding wall. The end of the snap-fit ​​component can extend into the slot and snap into the shielding door. A groove is provided on the side of the shielding door near the notch and above the cavity. A driving component extending into the cavity is installed at the bottom of the groove. One end of the driving component extending into the cavity can abut against the snap-fit ​​component, so that the end of the snap-fit ​​component is displaced to the outside of the slot.

[0011] Preferably, the driving mechanism includes a bidirectional threaded rod that is horizontally rotatably mounted on a slide rail. The bidirectional threaded rod is threadedly connected to two moving blocks, and an electric motor for driving the bidirectional threaded rod to rotate is fixedly mounted on the slide rail.

[0012] Preferably, the latching component includes a latching block and a spring telescopic rod. The top of the fixing plate extends above the slide rail, and an installation groove is provided on the side of the fixing plate extending above the slide rail and near the shielding door. A horizontal spring telescopic rod is fixedly installed on the fixing plate and in the installation groove. A latching block that can extend to the outside of the fixing plate is fixedly installed at the end of the spring telescopic rod. One end of the latching block that extends to the outside of the fixing plate can be inserted into the latching groove and latched with the shielding door. The driving component is used to hide the latching block in the installation groove.

[0013] Preferably, the driving component includes a driving sleeve, a guide plate, a vertical plate, a push plate, and a hinge rod. A horizontally oriented guide plate is fixedly installed inside the cavity on the side away from the slot. A push plate that can be inserted into the slot is movably sleeved outside the guide plate.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example: This utility model provides a technical solution for emergency-openable subway platform screen doors, such as... Figures 1-5 As shown, it includes:

[0029] Shielding wall 1, used for fixing to the subway platform;

[0030] The slide rail 2 has a notch 11 on the shielding wall 1. The slide rail 2 is fixedly installed on one side of the shielding wall 1 and located below the notch 11.

[0031] There are two sliders 3, which are symmetrically slidably installed on the top of the slide rail 2. A shielding door 31 is fixedly installed on the top of the sliders 3. When the two sliders 3 are close to each other on one side, the two shielding doors 31 are close to each other on the other side, and the gap 11 is blocked.

[0032] The sliding block 4 and the slide rail 2 are provided with a slide groove 21 on the side away from the shielding wall 1. There are two sliding blocks 4. The two sliding blocks 4 are symmetrically slidably installed in the slide groove 21. The slide rail 2 is equipped with a driving mechanism 5 that is connected to both sliding blocks 4. It is used to make the two sliding blocks 4 slide in opposite directions or stop sliding. The two sliding blocks 4 are fixedly installed with a fixing plate 6 on the outside of the slide rail 2.

[0033] The snap-fit ​​component 7 is mounted on the fixing plate 6. A cavity 311 is provided inside the shielding door 31. A slot 312 communicating with the cavity 311 is provided at the bottom of the shielding door 31 on the side away from the shielding wall 1. The end of the snap-fit ​​component 7 can extend into the slot 312 and snap into the shielding door 31. A groove 313 is provided on the side of the shielding door 31 near the notch 11 and above the cavity 311. A driving component 8 extending into the cavity 311 is installed at the bottom of the groove 313. One end of the driving component 8 extending into the cavity 311 can abut against the snap-fit ​​component 7 so that the end of the snap-fit ​​component 7 is displaced to the outside of the slot 312.

[0034] In use, the driving mechanism 5 causes the two moving blocks 4 to slide in opposite directions within the slide groove 21, thereby driving the two shielding doors 31 to slide in opposite directions towards or away from each other via the two fixed plates 6, thus achieving the opening and closing effect of the two shielding doors 31. Through the design of the driving component 8 and the locking component 7, when it is necessary to open the two shielding doors 31 urgently, the operator puts both hands into the grooves 313 on the two shielding doors 31 respectively, and the driving component 8 moves the end of the locking component 7 to the outside of the groove 312, canceling the locking state between the locking component 7 and the shielding door 31. At this time, the shielding door 31 can be directly pulled through the groove 313 to slide on the top of the slide rail 2, achieving the opening effect of the shielding door 31. During this process, the slider 3 slides on the slide rail 2 to guide the shielding door 31. This replaces the method of waiting for the central control room to issue an unlocking command and then having the operator manually pull the two shielding doors 31 to open, thus improving the opening efficiency of the two shielding doors 31.

[0035] As one embodiment: the driving mechanism 5 includes a bidirectional threaded rod 51 that is horizontally rotatably mounted on the slide rail 2. The bidirectional threaded rod 51 is threadedly connected to two moving blocks 4. A motor 52 for driving the bidirectional threaded rod 51 to rotate is fixedly mounted on the slide rail 2. In use, when the two shielding doors 31 are opened and closed, the motor 52 is controlled to work, and the output shaft of the motor 52 rotates, thereby driving the bidirectional threaded rod 51 to rotate on the slide rail 2. This causes the two moving blocks 4 to slide in opposite directions in the slide groove 21, thereby driving the two shielding doors 31 to move closer or further apart, thus opening and closing the two shielding doors 31.

[0036] As one embodiment: the latching component 7 includes a latching block 71 and a spring telescopic rod 72. The top of the fixing plate 6 extends above the slide rail 2, and a mounting groove 61 is provided on the side of the fixing plate 6 extending above the slide rail 2 and near the shielding door 31. A horizontal spring telescopic rod 72 is fixedly installed on the fixing plate 6 and located in the mounting groove 61. A latching block 71 that can extend to the outside of the fixing plate 6 is fixedly installed at the end of the spring telescopic rod 72. One end of the latching block 71 extending to the outside of the fixing plate 6 can be inserted into the latching groove 312 and latched with the shielding door 31. The driving component 8 is used to hide the latching block 71 in the mounting groove 61. In use, when it is necessary to open the shielding door 31 in an emergency, the driving component 8 hides the latching block 71 in the mounting groove 61. This cancels the engagement between the latching block 71 and the shielding door 31. When the latching block 71 and the shielding door 31 are locked together, a person applies a pressing force to the latching block 71, causing it to be hidden in the mounting groove 61. The spring telescopic rod 72 deforms under the force, pulling the shielding door 31 to move to the outside of the latching block 71, so that the end of the latching block 71 and the shielding door 31 come into contact. If the shielding door 31 is pulled continuously, when the locking groove 312 on the shielding door 31 moves to the latching block 71, the spring telescopic rod 72 returns to its natural state, thereby pushing the latching block 71 to move to the outside of the mounting groove 61, so that the end of the latching block 71 is inserted into the locking groove 312, locking the latching block 71 and the shielding door 31 together, thereby locking and positioning the fixing plate 6 and the shielding door 31 together.

[0037] As one embodiment: the driving component 8 includes a driving sleeve 81, a guide plate 82, a vertical plate 83, a push plate 84, and a hinge rod 85. A horizontally oriented guide plate 82 is fixedly installed inside the cavity 311 on the side away from the slot 312. A push plate 84, which can be inserted into the slot 312, is movably sleeved outside the guide plate 82. A vertically oriented vertical plate 83 is fixedly installed on the top of the guide plate 82. A driving sleeve 81, sleeved outside the vertical plate 83, moves vertically through the groove 313. The bottom of the driving sleeve 81 near the slot 312 is... A hinge rod 85 is provided, with the other end of the hinge rod 85 hinged to the top of the push plate 84. In use, the operator applies a pressing force to the drive sleeve 81, causing the drive sleeve 81 to slide downward outside the upright plate 83. The hinge rod 85 rotates around its own hinge point outside the drive sleeve 81, and the other end of the hinge rod 85 rotates between itself and the push plate 84, thereby pushing the push plate 84 to slide outside the guide plate 82, so that the end of the push plate 84 is inserted into the slot 312, pushing the locking block 71 to slide into the mounting groove 61 and thus hide inside the mounting groove 61.

[0038] As one embodiment: the end of the slide rail 2 is fixedly installed with a protective cover 22 that is sleeved on the outside of the motor 52 by screws. The design of the protective cover 22 achieves the protection effect of the motor 52.

[0039] As one embodiment: A pressing plate 811 is fixedly installed on the top of the driving sleeve 81. The outer side wall of the pressing plate 811 and the inner side wall of the groove 313 are in contact with each other. It is worth noting that: In this embodiment, the top of the pressing plate 811 and the bottom of the opening end of the groove 313 are on the same horizontal plane, which increases the aesthetics. Through the design of the pressing plate 811, the cross-section of the top of the driving sleeve 81 is increased, which makes it easier for personnel to apply pressing force to the pressing plate 811.

[0040] As one embodiment: an advertising pasting area 314 is provided on the shielding door 31 and on one side of the groove 313. The advertising pasting area 314 facilitates the pasting of billboards on the shielding door 31, thereby facilitating advertising display.

[0041] In specific implementation of this utility model:

[0042] When an emergency start is required for the shielding door 31, the operator places both hands into the grooves 313 on the two shielding doors 31 respectively, applies a pressing force to the pressing plate 811, causing the driving sleeve 81 to slide downward outside the upright plate 83. The hinge rod 85 rotates around its own hinge point outside the driving sleeve 81, and the other end of the hinge rod 85 rotates with the push plate 84, thereby pushing the push plate 84 to slide outside the guide plate 82, so that the end of the push plate 84 is inserted into the slot 312, pushing the locking block 71 to slide into the mounting groove 61 and hide inside the mounting groove 61, thus canceling the locking between the locking block 71 and the shielding door 31. At this time, the shielding door 31 can be directly pulled through the groove 313 to slide on the top of the slide rail 2, thus achieving the effect of opening the shielding door 31.

[0043] When it is necessary to secure the fixing plate 6 and the shielding door 31 together, the operator applies a pressing force to the locking block 71, causing it to be hidden in the mounting groove 61. The spring telescopic rod 72 deforms under the force, pulling the shielding door 31 to the outside of the locking block 71, so that the end of the locking block 71 and the shielding door 31 come into contact. As the shielding door 31 is pulled continuously, when the locking groove 312 on the shielding door 31 moves to the locking block 71, the spring telescopic rod 72 returns to its natural state, thereby pushing the locking block 71 to move out of the mounting groove 61, so that the end of the locking block 71 is inserted into the locking groove 312, locking the locking block 71 and the shielding door 31 together, thereby securing and positioning the fixing plate 6 and the shielding door 31 together.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
