Description

Technical Field

[0001] The utility model belongs to the technical field of screen doors, in particular to a platform screen door. Background Art

[0002] The shielding doors of subway platforms mainly include fixed doors that are fixedly installed and opening and closing doors that are installed on the fixed doors and can be opened and closed. During the closing process, the opening and closing doors usually have certain requirements for their sealing. If the sealing is not enough, a large amount of noise in the subway tunnel will be transmitted into the station, and the strong wind generated by squeezing the tunnel space when the train is running will also penetrate into the station through the door gap, causing discomfort to people waiting for the train on the platform.

[0003] In the current technology, the left and right door panels of the switch door are driven by connecting them through a circular cable, and a driving wheel for driving the cable to move is set on the back of the fixed door. The cable drive method has certain disadvantages when applied here. The driving wheel is difficult to tighten the cable during the transmission process of the cable, making it difficult to form a certain mutual resistance between the left and right door panels when they are closed, thereby affecting the sealing of the switch door when it is in the closed state. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and utility model name of this application to avoid blurring the purpose of this section, specification abstract and utility model name, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0005] In view of the following technical problems in the prior art: the platform screen door in the current technology is moved by a cable and a driving wheel, and due to the limitation of the structure, the cable is difficult to form a sufficient resistance between the two door panels, thereby affecting the sealing effect of the two door panels when they are closed. Therefore, the purpose of the utility model is to further improve the driving method for the two door panels in the current technology, so that the two door panels can be tightened against each other when they are closed, thereby improving the sealing effect when closed.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A platform screen door, comprising:

[0008] Fix doors and door panels;

[0009] A plurality of sliding blocks slidably arranged on the fixed door, wherein a plurality of locations of the door panel are respectively connected to the plurality of sliding blocks through a first spring assembly;

[0010] A pressing part provided on the fixed door, which cooperates with the slider, and when the slider reaches a fixed point, the pressing part applies force to the door panel;

[0011] A driving assembly is configured to drive the slider to move.

[0012] As a preferred technical solution for a platform screen door, the driving assembly includes a driving rod that is rotatably arranged relative to the fixed door and is threadedly engaged with the slider.

[0013] As a preferred technical solution for a platform screen door, a plurality of sliding blocks threadedly matched with the driving rod are respectively connected to the two door panels.

[0014] As an optimal technical solution for a platform screen door, it also includes a collar, a connecting column is constructed on the slider, the collar is fixedly arranged on the door panel and forms a ring sleeve for the connecting column.

[0015] As a preferred technical solution for a platform screen door, the first spring assembly includes springs respectively connected to two ends of the collar, which are sleeved on the connecting column and the other end of which is connected to the slider.

[0016] As a preferred technical solution for a platform screen door, the pressing part is movably arranged relative to the fixed door, and a second spring assembly is connected between the pressing part and the fixed door. When the slider moves to a fixed position, it exerts force on the pressing part.

[0017] As a preferred technical solution for a platform screen door, the pressing portion is arranged to rotate relative to the fixed door, and is configured with an inclined surface for contacting the sliding block.

[0018] The platform screen door provided by the utility model has the beneficial effect that, compared with the movable mode of the screen door door panel in the current technology, the elastic connection relationship between the slider and the door panel is used in the present solution. When the slider slides into place, the elastic force will form a mutual resistance effect between the left and right door panels, thereby helping to tighten the door gap. At the same time, the cooperation of the pressing part helps the door panel to resist to the side of the fixed door, thereby tightening the gap between the door panel and the fixed door, so as to improve the sealing effect of the entire screen door as a whole.

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention.

[0029] Reference Figure 1-4An embodiment of the utility model provides a platform screen door, including a fixed door 1 and a door panel 2 for opening and closing the door. The door panels 2 are two on the left and right sides, and the two door panels 2 on the left and right sides are a pair. In fact, there are multiple pairs. Only one pair is shown in the figure for reference. The utility model also includes the following parts:

[0030] A plurality of sliders 3 are slidably arranged on the fixed door 1, and each door panel 2 corresponds to a plurality of sliders 3. Several locations of the door panel 2 are respectively connected to the plurality of sliders 3 through the first spring assembly 4. The plurality of sliders 3 are distributed up and down, so as to be evenly connected to the upper and lower ends of the door panel 2. The door panel 2 is kept moving relative to the fixed door 1 through the cooperation of the sliders 3, so as to ensure that the door opening and closing actions can be performed;

[0031] The pressing part 5 provided on the fixed door 1 has a linkage relationship with at least one of the sliders 3. When the slider 3 reaches a fixed position, the pressing part 5 exerts a force on the door panel 2 in a direction approximately perpendicular to the panel surface.

[0032] A driving assembly 6 configured to drive the slider 3 to move;

[0033] Based on the above, when the door is opened or closed, the driving assembly 6 drives the slider 3 to slide, so as to drive the door panel 2 to move. When the left and right door panels 2 are close to each other, the slider 3 needs to continue to move a certain distance. At this time, the slider 3 reaches the fixed point position, that is, Figure 1-2 As shown in the state, a certain pulling force is applied to the door panel 2 through the spring 401 assembly, so that the two door panels 2 are in contact with each other to reduce the generation of gaps, thereby increasing the sealing effect between the two door panels 2. At the same time, through the linkage relationship, the pressing portion 5 applies a force to the door panel 2 in a direction almost perpendicular to the surface of the door panel 2, so that the door panel 2 can form a contact on the fixed door 1, thereby increasing the sealing effect at the contact between the door panel 2 and the fixed door 1, so as to improve the overall sealing of the entire shielding door when it is closed.

[0034] Further, see Figure 2-4 The driving assembly 6 includes a driving rod 601 that is rotatably arranged relative to the fixed door 1. The driving rod 601 can be rotatably arranged on the fixed door 1 or on the tunnel wall above and below the fixed door 1. The driving rod 601 is threadedly matched with the slider 3. In addition, the driving assembly 6 also includes a power element, such as a motor 602, which can be connected to the driving rod 601. There are two driving rods 601 in the figure, so as to respectively match the two sliders 3 distributed above and below. Figure 2As described in the figure, the motor and the driving rod 601 can be connected by the transmission rod 11; through the threaded cooperation between the driving rod 601 and the slider 3, when the driving rod 601 completes the driving of the slider 3, the slider 3 is automatically limited. During the closing process of the door panel 2, the slider 3 will not be loose at its position, thereby maintaining the sealing effect when the shielding door is closed.

[0035] Further, see Figure 2 The slider 3 connected to the left and right door panels 2 respectively has its thread engaged with the same driving rod 601, so that when driven as a whole, the actions between the two door panels 2 can maintain good uniformity, which helps to achieve a continuous action effect when opening and closing the door.

[0036] Further, see Figure 2-4 The utility model also includes a sleeve 7, and a connecting column 8 is constructed on the slider 3. The sleeve 7 is fixedly arranged on the door panel 2, and can be specifically formed as a whole with the frame of the door panel 2. The sleeve 7 forms a ring sleeve for the connecting column 8, thereby ensuring the connection between the slider 3 and the door panel 2. Therefore, even when the first spring assembly 4 is damaged or subjected to excessive force, the door panel 2 and the slider 3 will not be separated; the inner diameter of the sleeve 7 is larger than the outer diameter of the connecting column 8, so that the two can still maintain a certain relative activity, thereby not affecting the action process of the first spring assembly 4.

[0037] Further, see Figure 4 The first spring assembly 4 includes a spring 401 respectively connected to the two ends of the ring 7, which is sleeved on the connecting column 8, and the other end of the spring 401 is connected to the slider 3, thereby realizing an elastic connection between the slider 3 and the door panel 2; in this structure, the spring 401 is wound around the connecting column 8 to help protect the structure of the spring 401 and prevent it from being subjected to excessive force and causing irreversible deformation; through the separate design of the two springs 401, when the door panel 2 moves laterally on both sides relative to the slider 3, the two springs 401 respectively perform stretching and contraction movements, thereby helping to promote the elastic reset process of the spring 401 through mutual influence.

[0038] Further, see Figure 3Regarding the linkage between the pressing part 5 and the slider 3, the pressing part 5 and the fixed door 1 are relatively movable, and a second spring component 9 is connected between the pressing part 5 and the fixed door 1. The second spring component 9 adopts an elastic iron bar in the figure, which is used as a reference; in normal state, the pressing part is pushed to be separated from the frame of the door panel 2 under the action of the second spring component 9, and when the slider 3 moves to a fixed position, it will form a force on the pressing part 5, so that the pressing part 5 overcomes the elastic force of the second spring component 9 and moves to press the frame of the door panel 2, so that the door panel 2 as a whole is subjected to a force roughly consistent with the vertical direction of its own panel surface; this linkage form of the pressing part 5 makes its own activity process relatively simple and easy to implement, which helps to reduce the production cost.

[0039] Further, see Figure 3 Regarding the specific activity mode of the pressing part 5, the pressing part 5 and the fixed door 1 are arranged to rotate relative to each other. For example, the main part of the pressing part 5 can adopt a columnar structure and be directly rotatably installed on the back side of the fixed door 1 or the inner wall of the tunnel above and below the fixed door 1, and the pressing part 5 is constructed with an inclined surface 10 for contacting the slider 3. When the slider 3 reaches the fixed position, the inclined surface 10 is pushed to rotate the pressing part 5, so that it is pressed against the frame of the door panel 2 at one point; in this activity mode, the pressing part 5 can be kept moving with a lower activity amplitude, so as not to cause a large deflection, which is conducive to installation in a compact space.

[0040] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
