[0001] The utility model relates to door technical field especially relates to a shielding door. BACKGROUND

[0002] At present, shielding door can be applied to train, high speed train, subway platform, when train enters or leaves the station, shielding door can lock the passageway between platform and track through the horizontal movement of door row, effectively avoid the dangerous situation that passenger falls into track due to accident, improve the safety of passenger waiting.

[0003] In order to ensure that shielding door can stably move in frequent opening and closing process, the guiding device is usually arranged at the bottom of shielding door. However, the weight of door row and various external forces, such as wind force, passenger extrusion force and the like, are concentrated on the bottom guiding mechanism during the operation of door row, so that the bottom guiding mechanism bears larger pressure.

[0004] Taking the heavier subway platform shielding door as an example, the bottom guiding mechanism needs to bear the gravity of door row and impact force during opening and closing for a long time, which puts forward high requirement on the bearing capacity of bottom guiding mechanism, and easily causes excessive wear, deformation and even damage of bottom guide rail, sliding block and the like, not only reduces the guiding precision, but also may cause the jam phenomenon of door row during movement, which affects the normal operation of shielding door.

[0006] The utility model adopts the technical scheme that:

[0007] A shielding door comprises,

[0008] A machine case is provided with a mounting cavity;

[0011] A second guiding mechanism for guiding the linear movement of the lower end of the door row, which is installed between the bottom of the cabinet and the lower end of the door row and cooperates with the lower end of the door row.

[0012] Thus, the door row is double-constrained by the first guiding mechanism and the second guiding mechanism. The first guiding mechanism and the second guiding mechanism guide and limit the movement track of the door row from different height positions.

[0013] Further, the upper part of the cabinet is provided with a support plate, the sliding rail is installed on the support plate, and the sliding block is installed on the upper end of the door row.

[0014] Thus, the sliding block smoothly slides along the linear direction of the sliding rail, guiding the upper end of the door row to move in a linear direction, effectively preventing the upper end of the door row from shaking left and right or deviating from the predetermined track.

[0020] Thus, the wheel surface of the first guide wheel rollingly cooperates with the bottom wall of the guide groove, and the two end side walls of the first guide wheel in the axial direction are limitedly matched with the two side walls of the guide groove, guiding the door row to move in a straight line direction.

[0021] Further, the cabinet comprises a frame and a second panel, the mounting cavity is formed in the frame, the second panel is connected to the frame and covers the two sides of the mounting cavity; one end of the mounting cavity is provided with an opening, the mounting frame is arranged adjacent to the opening; the door row moves into or out of the mounting cavity through the opening.

[0022] Thus, when the door row enters or exits the mounting cavity through the opening, the second guide mechanism can prevent the door row from moving sideways or shaking when passing through the opening, ensuring that the door row smoothly enters and exits the mounting cavity along the accurate trajectory, and ensuring the normal opening and closing action of the shielding door.

[0023] Further, a driving mechanism is further arranged, the driving mechanism is arranged in the mounting cavity and above the door row; the driving mechanism is in transmission connection with the door row.

[0024] Thus, under the action of the driving mechanism, the door row overcomes the friction and other resistance and moves quickly and stably until reaching the preset opening or closing position.

[0026] Thus, the driving mechanism can efficiently convert the rotary power of the driving motor into the linear movement power of the door row through the cooperation of the synchronous belt, the driving wheel and the driven wheel, so that the shielding door can accurately stop at the preset position during opening and closing.

[0027] Further, the connecting piece comprises a first clamping plate, a second clamping plate and a connecting arm, the first clamping plate and the second clamping plate are oppositely arranged on both sides of the synchronous belt and clamp the synchronous belt, and the two ends of the connecting arm are respectively connected with the second clamping plate and the door row.

DETAILED DESCRIPTION

[0044] In order to better understand and implement, the technical scheme in the utility model embodiment will be clearly and completely described below in combination with the drawings in the utility model embodiment.

[0045] In the description of the utility model, it should be explained that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the utility model.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.

[0047] Referring to Figure 1 , Figure 2 and Figure 5 , the utility model discloses a shielding door, it includes the case 10, the door row 20, be used to guide the first guide mechanism 30 of the upper end of door row 20 along linear motion and be used to guide the second guide mechanism 40 of the lower end of door row 20 along linear motion. Specifically, the case 10 is equipped with the mounting cavity 11, and the door row 20 is movably installed in the mounting cavity 11. Referring to Figure 2 and Figure 6 , the first guide mechanism 30 includes slide rail 31 and sliding block 32, wherein the slide rail 31 is installed on the upper portion of the case 10, the sliding block 32 is fixedly connected with the door row 20, and the sliding block 32 is slidingly connected on the slide rail 31. Referring to Figure 2 and Figure 5 , the second guide mechanism 40 is installed between the bottom of the case 10 and the lower end of the door row 20, and is matched with the lower end of the door row 20.

[0048] On the basis of this structure, when the shielding door of the utility model is used, it can be installed on the waiting platform of the subway and high-speed rail to isolate the platform and the track when the train enters or departs the station; it can also be applied to the entrance of the residence and parking lot to restrict pedestrians and vehicles.

[0049] When using, when the shielding door needs to be opened, the door row 20 can be manually pulled or driven by the driving mechanism 50 to move outward relative to the case 10 to a preset position, so as to block the passage. When the shielding door needs to be closed, the door row 20 is moved inward relative to the case 10 to a preset position, so as to open the passage, and the door row 20 is stored in the case 10.

[0050] During the movement of the door row 20 relative to the case 10, the first guide mechanism 30 slides on the slide rail 31 through the sliding block 32 to guide the upper end of the door row 20 to move along the linear direction of the slide rail 31, and the second guide mechanism 40 guides the lower end of the door row 20 to move along the linear direction, so that the upper and lower ends of the door row 20 are guided in the same linear direction, and the door row 20 can stably move, and the problem that the upper end and the lower end of the door row 20 deviate to cause the movement of the door row 20 to be blocked when the door row 20 is subjected to external force is avoided.

[0051] It should be noted that the slide rail 31 is installed on the cabinet 10 and connected with the slide block 32 on the door row 20, the slide rail 31 can support the upper end of the door row 20, share part of the gravity of the door row 20 and the external force received, and transmit and disperse the force to the cabinet 10. The second guide mechanism 40 can be installed on the ground or the cabinet 10 and located at the lower end of the door row 20, which can support the lower end of the door row 20 and transmit and disperse part of the gravity of the door row 20 and the external force received to the ground or the cabinet 10.

[0052] Therefore, by the setting of the first guide mechanism 30 and the second guide mechanism 40, the door row 20 is formed with double constraints from top to bottom. The first guide mechanism 30 and the second guide mechanism 40 guide and limit the moving track of the door row 20 from different height positions, and the two guide mechanisms act together to greatly improve the guiding accuracy of the movement of the door row 20 and reduce the track deviation caused by the uneven wear or uneven force caused by the long-term bearing of gravity of the lower end guide mechanism.

[0053] In addition, the bottom end of the door row 20 is directly supported and guided by the second guide mechanism 40, avoiding the contact of the door row 20 with the ground and eliminating the movement deviation caused by the uneven ground. The movement of the door row 20 is not limited by the ground environment.

[0054] Further, referring to Figure 2 and Figure 3 , the upper part of the cabinet 10 is provided with a support plate 12, the slide rail 31 is installed on the support plate 12, referring to Figure 6 , the slide block 32 is installed on the upper end of the door row 20.

[0055] On the basis of this structure, during assembly, the support plate 12 can be first installed on the upper part of the cabinet 10 by screws, bolts and other fasteners, then the slide rail 31 is installed on the bottom end face of the support plate 12, then the slide block 32 is connected to the upper end face of the door row 20 by screws, then the door row 20 is installed into the mounting cavity 11, and the slide block 32 is clamped on the slide rail 31 from one end of the slide rail 31.

[0056] When the door row 20 moves under the action of external force, the slide block 32 at the top of the door row 20 will slide on the slide rail 31 to make the door row 20 move along the direction of the slide rail 31.

[0057] Therefore, the slide block 32 smoothly slides along the linear direction of the slide rail 31, guiding the upper end of the door row 20 to move in a linear direction, effectively preventing the upper end of the door row 20 from shaking or deviating from the predetermined track.

[0058] The slide rail 31 is fixed on the support plate 12, and the support plate 12 provides a reliable mounting base for the slide rail 31, ensuring the stability of the first guide mechanism 30, so that the door row 20 moves stably, avoiding the security risks caused by the shaking or deviation of the door row 20. At the same time, part of the weight of the door row 20 is transmitted to the slide rail 31 through the sliding block 32 connected to the upper end of the door row 20, and then borne by the support plate 12. This not only reduces the load of the second guide mechanism 40 at the bottom of the door row 20, but also makes the stress of the entire door row 20 more uniform.

[0059] Embodiment Two

[0060] This embodiment further describes a structure of the second guide mechanism 40 on the basis of the structure of Embodiment One:

[0061] In this embodiment, referring to Figure 2 , Figure 3 and Figure 4 , the mounting frame 41 is arranged at the bottom of the cabinet 10, the second guide mechanism 40 includes the first guide wheel 42 and the second guide wheel 43. Specifically, the wheel shaft of the first guide wheel 42 is transversely rotatably mounted on the mounting frame 41, and the first guide wheel 42 is in rolling connection with the bottom of the door row 20. The wheel shaft of the second guide wheel 43 is vertically rotatably mounted on the mounting frame 41, and the second guide wheel 43 is in rolling connection with the lower end side of the door row 20.

[0062] On the basis of this structure, when assembling, the mounting frame 41 can be connected to the cabinet 10 through screws, bolts or other fasteners and located at the bottom of the mounting cavity 11, and then the first guide wheel 42 and the second guide wheel 43 are mounted on the mounting frame 41. Then the door row 20 is installed into the mounting cavity 11, and the bottom of the door row 20 is in rolling cooperation with the first guide wheel 42, and the lower end side of the door row 20 is in rolling cooperation with the second guide wheel 43.

[0063] Among them, the first guide wheel 42 and the second guide wheel 43 can be provided with one or more. When the first guide wheel 42 is provided with multiple, multiple first guide wheels 42 are arranged at intervals along the length direction of the cabinet 10. When the second guide wheel 43 is provided with multiple, multiple second guide wheels 43 can be arranged on one side or both sides of the lower end of the door row 20 along the length direction of the cabinet 10.

[0064] When the door row 20 moves, the first guide wheel 42 at the bottom of the door row 20 will start to rotate under the action of the movement of the door row 20 due to the direct contact with the door row 20, thereby being able to support the forward movement of the bottom of the door row 20. The second guide wheel 43 at the side is in close contact with the lower end side of the door row 20 and rotates, preventing the door row 20 from moving sideways and ensuring that the door row 20 moves along the predetermined straight trajectory.

[0065] Thus, the second guiding mechanism 40 guides the door row 20 from different directions through the first guiding wheel 42 at the bottom of the door row 20 and the second guiding wheel 43 at the lower end side of the door row 20. The first guiding wheel 42 ensures the stable movement of the bottom of the door row 20 in the horizontal direction, preventing the door row 20 from rising and falling or shaking left and right; the second guiding wheel 43 limits the lateral movement of the door row 20 perpendicular to the moving direction, ensuring that the door row 20 moves along a straight line during movement. The second guiding mechanism 40 cooperates with the first guiding mechanism 30 at the upper end of the door row 20, greatly enhancing the stability and precision of the movement of the door row 20, avoiding various problems caused by guiding deviation, and improving the reliability of the operation of the shielding door.

[0066] In addition, the second guiding mechanism 40 uses a mounting bracket 41 to connect the rotatable first guiding wheel 42 and the second guiding wheel 43, which can facilitate the inspection, cleaning and lubrication of the guiding wheels and the mounting bracket 41 during routine maintenance. When the guiding wheels wear out or fail, they are also easy to disassemble and replace.

[0067] Further, the second guiding wheel 43 is provided with at least two groups, and the at least two groups of second guiding wheels 43 are oppositely arranged on both sides of the mounting bracket 41, wherein the lower end of the door row 20 is located between the two sides of the mounting bracket 41.

[0068] When the door row 20 is installed into the mounting cavity 11, the two groups of second guiding wheels 43 are oppositely arranged on both sides of the door row 20, which can provide stable lateral support for the door row 20. When the train rapidly enters and exits the station, strong air currents will form lateral impact on the door row 20. At this time, the two oppositely arranged second guiding wheels 43 can jointly resist these lateral forces, preventing the door row 20 from moving sideways, shaking or tilting.

[0069] Thus, compared to only one group of second guiding wheels 43, the two groups of second guiding wheels 43 work together to provide precise guidance for the lateral movement of the door row 20 during movement of the door row 20, so that the door row 20 can move along the predetermined straight line direction during opening and closing, reducing problems such as collision of the door row 20 with the surrounding structure and inaccurate alignment caused by guiding deviation.

[0070] Embodiment Three

[0071] This embodiment further describes another structure of the second guiding mechanism 40 based on the structure of Embodiment One:

[0072] In this embodiment, referring to Figure 5 and Figure 7A mounting frame 41 is arranged at the bottom of the cabinet 10, and the second guide mechanism 40 comprises a first guide wheel 42 and a guide groove 24, wherein the guide groove 24 is arranged at the bottom of the door row 20, the wheel shaft of the first guide wheel 42 is transversely rotatably arranged on the mounting frame 41, and the first guide wheel 42 is rollingly connected in the guide groove 24.

[0073] On the basis of the above structure, when assembling, the mounting frame 41 can be first connected to the cabinet 10 by screws, bolts or other fasteners and arranged at the bottom of the mounting cavity 11. Then the wheel shaft of the first guide wheel 42 is arranged on the mounting frame 41 through bearing supports. Then the guide groove 24 is arranged at the bottom of the door row 20, and the assembled door row 20 is arranged in the mounting cavity 11, and the first guide wheel 42 is arranged in the guide groove 24.

[0074] Specifically, the guide groove 24 extends along the length direction of the door row 20, and the guide groove 24 has a downwardly arranged slot, the first guide wheel 42 extends into the guide groove 24 through the slot, and the width of the guide groove 24 is matched with the axial length of the first guide wheel 42. The wheel surface of the first guide wheel 42 is rollingly matched with the bottom wall of the guide groove 24, and the two end side walls of the first guide wheel 42 in the axial direction are limitedly matched with the two side walls of the guide groove 24.

[0075] The guide groove 24 can be a separate component arranged on the lower cross beam 22 of the door row 20 through screws, bolts or other fasteners. The guide groove 24 can also be integrally formed at the bottom of the door row 20.

[0076] When the door row 20 moves, the wheel surface of the first guide wheel 42 rolls in the guide groove 24 under the driving of the door row 20, guiding the door row 20 to move in a straight line. At the same time, the two end side walls of the first guide wheel 42 in the axial direction interact with the two side walls of the guide groove 24, limiting the door row 20 from deviating towards the horizontal direction perpendicular to the guide groove 24.

[0077] Therefore, the second guide mechanism 40 at the lower end of the door row 20 cooperates with the first guide mechanism 30 at the upper end of the door row 20 to guide the door row 20 to move in the same straight line, ensuring the accuracy of the moving direction of the door row 20.

[0078] Compared with the second embodiment, the straight line movement of the door row 20 is guided and the side is limited by the guide groove 24 and the first guide wheel 42, and the second guide wheel 43 can be omitted.

[0079] Embodiment Four

[0080] On the basis of the above-mentioned embodiments, the other structures of the shielding door are described:

[0081] Referring to Figure 3The cabinet 10 comprises a frame 15 and a second panel 14, the mounting cavity 11 is formed in the frame 15, and the second panel 14 is connected to the frame 15 and covers two sides of the mounting cavity 11. One end of the mounting cavity 11 is provided with an opening 13, the mounting rack 41 is arranged adjacent to the opening 13, and the door row 20 moves into or out of the mounting cavity 11 through the opening 13.

[0082] Therefore, when the door row 20 enters or exits the mounting cavity 11 through the opening 13, the first guide wheel 42 and the second guide wheel 43 in the second guide mechanism 40 can realize the guiding effect. The first guide wheel 42 guides the stable movement of the bottom of the door row 20; the second guide wheel 43 limits the lateral displacement of the door row 20, prevents the door row 20 from being laterally displaced and shaken when passing through the opening 13, and ensures that the door row 20 smoothly enters and exits the mounting cavity 11 along the accurate track, thereby guaranteeing the normal opening and closing action of the shielding door.

[0083] Referring to Figure 6 The door row 20 comprises a support frame and a first panel 21. Specifically, the support frame comprises two groups of vertical beams 23 arranged oppositely and two groups of horizontal beams 22 arranged oppositely, and the vertical beams 23 and the horizontal beams 22 are sequentially connected end to end to form a rectangular support frame. The first panel 21 is connected to two sides of the support frame. In addition, the sliding block 32 is installed on the horizontal beam 22 located above.

[0084] On the basis of the structure, when assembling, first, the two groups of vertical beams 23 arranged oppositely and the two groups of horizontal beams 22 arranged oppositely are sequentially connected end to end, and are fixed by using connecting members 60 such as bolts and nuts to form a rectangular support frame, and then the sliding block 32 is installed on the horizontal beam 22 located above. Then, the first panel 21 is connected to two sides of the rectangular support frame, which can be fixed by using screws, buckles or the like. Then, the door row 20 is installed into the mounting cavity 11 of the cabinet 10.

[0085] The rectangular support frame structure ensures the overall rigidity of the door row 20, so that the acting force of each guide component can be uniformly transmitted. The end portion of the support frame provided with the sliding block 32 can only move in the mounting cavity 11 due to the influence of the stroke of the sliding block 32, which can provide support for the support frame portion extending out of the mounting cavity 11 to prevent it from falling down.

[0086] Further, the shielding door further comprises a driving mechanism 50. Specifically, the driving mechanism 50 is installed in the mounting cavity 11 and located above the door row 20. The driving mechanism 50 is in transmission connection with the door row 20.

[0087] On the basis of the structure, the support plate 12 divides the mounting cavity 11 into a first mounting cavity 11 and a second mounting cavity 11, wherein the driving mechanism 50 is mounted in the first mounting cavity 11 and supported on the support plate 12, and the door row 20 is mounted in the second mounting cavity 11 and is in transmission connection with the door row 20 through a transmission device (such as a chain, a belt, or a gear, etc.).

[0088] When the driving mechanism 50 starts to start, it transmits power to the door row 20 through the transmission device. At this time, the slider 32 connected to the upper end of the door row 20 starts to slide on the slide rail 31 under the traction of the driving mechanism 50, providing horizontal movement guidance for the upper end of the door row 20; the two groups of second guide wheels 43 on both sides of the lower cross beam 22 start to rotate when the door row 20 moves, ensuring the lateral stability of the lower end of the door row 20 and preventing the door row 20 from moving sideways; the first guide wheel 42 at the bottom rotates under the force of the bottom of the door row 20, pushing the bottom of the door row 20 to move forward.

[0089] Therefore, under the power of the driving mechanism 50, the door row 20 overcomes the friction and other resistance and moves quickly and smoothly until it reaches the preset opening or closing position.

[0090] In addition, the cabinet 10 further comprises a cover plate 16, and the top of the frame 15 is provided with a mounting groove 17, and after all the components are mounted in the frame 15, the cover plate 16 is covered in the mounting groove 17. Since the driving mechanism 50 is located at the upper part of the support frame, when the driving mechanism 50 is overhauled, only the cover plate 16 can be disassembled; and when the door row 20 and the guide assembly are overhauled, the second panel 14 can be disassembled.

[0091] Further, referring to Figure 9 , the driving mechanism 50 comprises a driving motor 51, a synchronous belt 52, a driving wheel 53, and a driven wheel 54. Specifically, the two ends of the synchronous belt 52 are arranged around the driving wheel 53 and the driven wheel 54 respectively, and the driving motor 51 is used to drive the driving wheel 53 to rotate to drive the synchronous belt 52 to move. Wherein, the door row 20 is connected with the synchronous belt 52 through a connecting piece 60.

[0092] On the basis of the structure, when assembling, the driving wheel 53 and the driven wheel 54 can be installed on the support plate 12 in a horizontal direction, then the two ends of the synchronous belt 52 are arranged around the outside of the driving wheel 53 and the driven wheel 54 respectively, and then the driving motor 51 is mounted on the support plate 12 and in transmission connection with the driving wheel 53.

[0093] In use, the driving motor 51 starts to operate and outputs a rotating power, which is transmitted to the driving wheel 53 to make the driving wheel 53 start to rotate. Since the two ends of the synchronous belt 52 are respectively arranged around the driving wheel 53 and the driven wheel 54, the synchronous belt 52 will be driven to move linearly when the driving wheel 53 rotates. The connecting member 60 on the door row 20 is connected with the synchronous belt 52, so that the linear movement of the synchronous belt 52 will be transmitted to the door row 20 through the connecting member 60 to drive the door row 20 to move horizontally under the guidance of the first guide mechanism 30 and the second guide mechanism 40, thereby realizing the opening and closing actions of the shielding door.

[0094] Therefore, the driving mechanism 50 can efficiently convert the rotating power of the driving motor 51 into the linear movement power of the door row 20 through the cooperation of the synchronous belt 52, the driving wheel 53 and the driven wheel 54, so that the shielding door can be accurately stopped at the preset position during the opening and closing process.

[0095] Further, referring to Figure 6 and Figure 8 , the connecting member 60 comprises a first clamping plate 61, a second clamping plate 64 and a connecting arm 62. Specifically, the first clamping plate 61 and the second clamping plate 64 are oppositely arranged on the two sides of the synchronous belt 52 and clamp the synchronous belt 52. The two ends of the connecting arm 62 are respectively connected with the second clamping plate 64 and the door row 20.

[0096] On the basis of the above structure, during assembly, the driving mechanism 50 can be first installed in the mounting cavity 11, then the second clamping plate 64 is installed on the top of the door row 20 through the connecting arm 62, then the assembled door row 20 is installed into the mounting cavity 11, then the first clamping plate 61 and the second clamping plate 64 are oppositely arranged and respectively placed on the two sides of the synchronous belt 52, and the first clamping plate 61 and the second clamping plate 64 are fixed by fastening components such as bolts and nuts to tightly clamp the synchronous belt 52.

[0097] When the shielding door is opened or closed, the synchronous belt 52 starts to move under the driving of the driving wheel 53. Since the first clamping plate 61 and the second clamping plate 64 tightly clamp the synchronous belt 52, the movement of the synchronous belt 52 will drive the first clamping plate 61 and the second clamping plate 64 to move together. The connecting arm 62 connected with the second clamping plate 64 moves accordingly, and then transmits the movement force of the synchronous belt 52 to the door row 20 through the connecting arm 62 to drive the door row 20 to move horizontally, thereby realizing the opening or closing action of the shielding door.

[0098] Therefore, during the frequent movement of the driving mechanism 50 driving the synchronous belt 52, the clamping force of the first clamping plate 61 and the second clamping plate 64 ensures that the synchronous belt 52 will not fall off from the connecting member 60, guarantees that the power is continuously and stably transmitted from the synchronous belt 52 to the door row 20, avoids the abnormal movement of the door row 20 caused by loose connection, and ensures the reliable operation of the shielding door.

[0099] The connecting piece 60 is easy to install and dismount. During the installation stage, the first clamping plate 61 and the second clamping plate 64 can be clamped on the synchronous belt 52 and connected with the door row 20 through the connecting arm 62, so that the installation efficiency is improved. During the maintenance, the synchronous belt 52, the door row 20 or the connecting piece 60 itself can be conveniently inspected and replaced, so that the equipment downtime is reduced and the maintenance cost is reduced.

[0100] In addition, the connecting arm 62 is a short plate extending vertically, the upper end of the connecting arm 62 is connected with the second clamping plate 64, the lower end of the connecting arm 62 is connected with a connecting section 66 extending horizontally, and the connecting section 66 is installed on the upper end of the frame 15 of the door row 20 through fasteners such as screws or bolts. In addition, a connecting plate 63 can be connected with the connecting section 66, and the sliding block 32 is installed on the connecting plate 63, and the connecting plate 63 is installed on the two sides of the upper cross beam 22 of the door row 20 through the bottom mounting plate 65. In this way, when the sliding block 32 is connected with the sliding rail 31, the power of the driving mechanism 50 can be transmitted to the sliding block 32 through the connecting plate 63, so that the sliding block 32 slides on the sliding rail 31.

[0101] Further, the outer periphery of the driving wheel 53 and the driven wheel 54 is provided with first meshing teeth, the inner side of the synchronous belt 52 is provided with second meshing teeth, and the side of the first clamping plate 61 and the second clamping plate 64 clamped with the synchronous belt 52 is provided with third meshing teeth, wherein the second meshing teeth are meshed with the first meshing teeth, and the third meshing teeth are meshed with the second meshing teeth.

[0102] Therefore, the synchronous belt 52 is meshed with the driving wheel 53 and the driven wheel 54 through the second meshing teeth and the first meshing teeth, so that the slipping between the synchronous wheel and the synchronous belt 52 can be prevented, the power can be transmitted more accurately, and the energy loss is reduced. The first clamping plate 61 and the second clamping plate 64 are meshed with the synchronous belt 52 through the third meshing teeth and the second meshing teeth, so that the first clamping plate 61 and the second clamping plate 64 can provide greater friction, and ensure that the synchronous belt 52 and the two clamping plates do not slip.

[0103] In addition, the shielding door can be used in a single opening mode, that is, one case 10 and one door row 20 are provided, and the door row 20 extends out or extends into one side of the case 10. Two shielding doors can also be used in a double opening mode, that is, two cases 10 and two door rows 20 are provided, and the two door rows 20 extend out or extend into the opposite sides of the two cases 10.

[0104] The technical means disclosed by the utility model scheme are not limited to the technical means disclosed by the above-mentioned embodiments, and also include technical schemes composed of any combination of the above technical features. It should be noted that, for ordinary skilled persons in the art, without departing from the principles of the utility model, a number of improvements and refinements can be made, and these improvements and refinements are also considered within the protection scope of the utility model.
