Description

Technical Field

[0001] The present application relates to the technical field of electromagnetic shielding, and particularly to a shielding door device. Background Art

[0002] The shielding door is one of the important devices of the electromagnetic shielding chamber, which provides a passage for personnel and equipment to enter and exit while meeting the shielding effectiveness requirements of the electromagnetic shielding chamber. In addition, affected by the installation control and shielding effectiveness requirements, the shielding door adopts a knife spring sealing shielding structure. Specifically, the shielding door includes a door frame, a door panel and a door shaft. A knife edge provided with a reed is installed on the door frame, and a door knife is installed on the door panel. The electromagnetic shielding is achieved by the combination of the door knife and the knife edge.

[0003] Figure 1 is a schematic diagram of the existing shielding door in the closed state. Figure 2 is a schematic diagram of the existing shielding door during the opening or closing process. Refer to Figure 1 and Figure 2 As shown, the door panel 300 is connected to the door frame through a pivoting mechanism 400. The door frame is provided with door knife grooves 111, 112, and the door panel 300 is provided with door knives 310, 320 corresponding to the door knife grooves 111, 112. Reed pieces are arranged in the door knife grooves 111, 112. When the shielding door is closed, the door knives 310, 320 are respectively inserted into the corresponding door knife grooves 111, 112 and abut against the reed pieces in the door knife grooves 111, 112, thereby achieving the shielding effect. When the shielding door is opened, the door knives 310, 320 are disengaged from the door knife grooves 111, 112.

[0004] However, referring to Figure 1 and Figure 2 As shown, when the staff opens and closes the shielding door, the door knives 310, 320 on the door panel 300 move along an arc trajectory around the pivoting mechanism 400. Therefore, the trajectories of the door knives 310, 320 when inserted into the door knife grooves 111, 112 and when disengaged from the door knife grooves 111, 112 are also arc-shaped. Thus, after long-term use, the reed pieces are likely to be deformed. Therefore, after long-term use of the shielding door, electromagnetic leakage may occur, affecting the normal use of the shielding door, and in severe cases, it may even threaten the service life of the shielding door.

[0005] Aiming at the technical problem in the above-mentioned existing technology that when opening or closing the door panel of the existing shielding door, the trajectory of the movement of the door panel is arc-shaped, so after long-term use of the shielding door, the reed pieces are likely to be deformed, and thus electromagnetic leakage may occur, affecting the normal use of the shielding door, and in severe cases, it may even threaten the service life of the shielding door, no effective solution has been proposed yet. Summary of the Invention

[0006] The present disclosure provides a platform screen door device, which at least solves the technical problem in the prior art that since the existing platform screen door has an arc-shaped trajectory during the movement of the door panel when opening or closing the door panel, after long-term use of the platform screen door, the reed is likely to be deformed, so electromagnetic leakage may occur, affecting the normal use of the platform screen door, and in severe cases, it may also threaten the service life of the platform screen door.

[0007] According to one aspect of the present application, a platform screen door device is provided, including: a door frame, a door panel fixing assembly, and a door panel, wherein a door knife groove is provided on the outer surface of the door frame facing the door panel; the door panel fixing assembly is connected to the door frame and can linearly move along a linear displacement direction perpendicular to the plane defined by the door frame; and a door knife corresponding to the door knife groove is provided on the inner surface of the door panel facing the door frame, and is rotatably fixed to the door panel fixing assembly through a pivoting mechanism.

[0008] As can be seen from the above, different from the existing platform screen door device, the door panel in the present application is not directly fixed to the door frame, but is fixed to the door panel fixing assembly, and the door panel fixing assembly is connected to the door frame. Therefore, when the door panel fixing assembly is movable relative to the door frame, the door panel rotatably connected to the door panel fixing assembly is also movable relative to the door frame.

[0009] Furthermore, since the door panel fixing assembly can linearly move along a linear displacement direction perpendicular to the plane defined by the door frame (that is, the door panel fixing assembly can linearly translate relative to the door frame), the door panel rotatably connected to the door panel fixing assembly can also linearly move along a linear displacement direction perpendicular to the plane defined by the door frame (that is, the door panel can linearly translate relative to the door frame).

[0010] Therefore, when the door panel fixed to the door panel fixing assembly rotates to a position exactly parallel to the door frame, the door panel fixing assembly drives the door panel to translate towards the door frame, so that the door knife provided on the door panel can be inserted into the door knife groove provided on the door frame in a perpendicular form, and neither the door knife nor the door knife groove will be worn due to the opening or closing of the door panel.

[0011] Thus, through the above product structure, the technical effect is achieved that even after long-term use of the platform screen door, the normal use of the platform screen door can be guaranteed, and the service life of the platform screen door can be extended. Furthermore, it solves the technical problem in the prior art that since the existing platform screen door has an arc-shaped trajectory during the movement of the door panel when opening or closing the door panel, the wear on the reed or the door knife may be abnormal wear, so after long-term use of the platform screen door, the reed is likely to be deformed, so electromagnetic leakage may occur, affecting the normal use of the platform screen door, and in severe cases, it may also threaten the service life of the platform screen door.

[0030] Figure 3 is a schematic diagram of the assembly of the door panel and the door frame according to the embodiments of the present application; Figure 4 is a schematic diagram of the screen door device according to the embodiments of the present application. Refer to Figure 3 and Figure 4As shown in the figure, a platform screen door device includes: a door frame 100, a door panel fixing component 200, and a door panel 300. The outer surface of the door frame 100 facing the door panel 300 is provided with door knife grooves 111, 112; the door panel fixing component 200 is connected to the door frame 100 and can linearly move along a linear displacement direction perpendicular to the plane defined by the door frame 100; and the inner surface of the door panel 300 facing the door frame 100 is provided with door knives 310, 320 corresponding to the door knife grooves 111, 112, and is rotatably fixed to the door panel fixing component 200 through a pivoting mechanism 400.

[0031] As described in the background art, in the existing opening and closing manner of platform screen doors, in most cases, one side of the door panel is connected to the door frame through a door hinge, and the other side opens and closes. Figure 1 is a schematic diagram of an existing platform screen door in the closed state, Figure 2 is a schematic diagram of an existing platform screen door during the opening or closing process, refer to Figure 1 and Figure 2 As shown, the door panel 300 is connected to the door frame through a pivoting mechanism 400. The door frame is provided with door knife grooves 111, 112, and the door panel 300 is provided with door knives 310, 320 corresponding to the door knife grooves 111, 112. Reed pieces are arranged in the door knife grooves 111, 112. When the platform screen door is closed, the door knives 310, 320 are respectively inserted into the corresponding door knife grooves 111, 112 and abut against the reed pieces in the door knife grooves 111, 112, thereby achieving the shielding effect. When the platform screen door is opened, the door knives 310, 320 are disengaged from the door knife grooves 111, 112.

[0032] However, referring to Figure 1 and Figure 2 As shown, when the staff opens and closes the platform screen door, the door knives 310, 320 on the door panel 300 move along an arc trajectory around the pivoting mechanism 400. Therefore, the trajectories of the door knives 310, 320 when inserted into the door knife grooves 111, 112 and when disengaged from the door knife grooves 111, 112 are also arc-shaped. After long-term use, it is easy to cause the reed pieces to deform. Therefore, after long-term use of the platform screen door, electromagnetic leakage may occur, thus affecting the normal use of the platform screen door, and in severe cases, it may even threaten the service life of the platform screen door.

[0033] In view of this, the present application provides a platform screen door device. The platform screen door device includes a door frame 100, a door panel fixing component 200, and a door panel 300. Among them, a door knife groove 111, 112 is provided on the outer surface of the door frame 100 facing the door panel 300. The door panel fixing component 200 is connected to the door frame 100 and can linearly move in a direction perpendicular to the plane defined by the door frame 100. A door knife 310, 320 corresponding to the door knife groove 111, 112 is provided on the inner surface of the door panel 300 facing the door frame 100, and is rotatably fixed to the door frame fixing component 200 through a pivoting mechanism 400.

[0034] Therefore, as shown in Figure 3 and Figure 4 , different from the prior art, the door panel 300 in the present application is not directly fixed to the door frame 100, but is rotatably fixed to the door panel fixing component 200, and the door panel fixing component 200 is connected to the door frame 100. Therefore, when the door panel fixing component 200 is movable relative to the door frame 100, the door panel 300 rotatably connected to the door panel fixing component 200 is also movable relative to the door frame 100, and the moving direction and moving track of the door panel 300 are the same as those of the door panel fixing component 200.

[0035] Furthermore, since the door panel fixing component 200 can linearly move along the linear displacement direction perpendicular to the plane defined by the door frame 100 (that is, the door frame fixing component 200 can move towards the door frame 100 in a translational manner or move away from the door frame 100 in a translational manner), the door panel 300 rotatably connected to the door frame fixing component 200 can also linearly move along the linear displacement direction perpendicular to the plane defined by the door frame 100 (that is, the door panel 300 can move towards the door frame 100 in a translational manner or move away from the door frame 100 in a translational manner). That is, the door knives 310, 320 provided on the door panel 300 can move towards the door knife groove 111, 112 in a translational manner or move away from the door knife groove 111, 112 in a translational manner.

[0036] Therefore, Figure 5A is a schematic diagram during the closing process of the door panel in the platform screen door according to the embodiment of the present application, Figure 5B is a schematic diagram of the door knife inserted into the door knife groove in a vertical form in the platform screen door according to the embodiment of the present application, Figure 5C is a schematic diagram of the closed state of the platform screen door according to the embodiment of the present application.

[0037] First, as shown in Figure 5A , when it is necessary to close the door panel 300 in the platform screen door device, the door panel 300 fixed to the door panel fixing component 200 rotates around the pivoting mechanism 400.

[0038] Then, referring to Figure 5B as shown, the door panel 300 rotates around the pivot mechanism 400 to a position exactly parallel to the door frame 100. Further, the door panel 300 is locked with the door panel fixing assembly 200, and the door panel fixing assembly 200 drives the door panel 300 to translate towards the door frame 100 along a linear displacement direction perpendicular to the plane defined by the door frame 100.

[0039] Finally, referring to Figure 5C as shown, the door knives 310, 320 provided on the door panel 300 are inserted vertically into the door knife slots 111, 112 provided on the door frame 100.

[0040] Further,[[]] Figure 5D is a schematic diagram of the opened state of the screen door according to an embodiment of the present application; Figure 5E is a schematic diagram of the door knife on the screen door disengaging from the door knife slot vertically according to an embodiment of the present application; Figure 5F is a schematic diagram of the door panel during the opening process of the screen door according to an embodiment of the present application.

[0041] First, referring to Figure 5D as shown, in the case where it is necessary to open the door panel 300 in the screen door device, the door panel fixing assembly 200 is about to drive the door panel 300 to linearly move along a linear displacement direction perpendicular to the plane defined by the door frame 100 and move away from the door frame 100.

[0042] Then, referring to Figure 5E as shown, the door panel fixing assembly 200 drives the door panel 300 locked with the door panel fixing assembly 200 to linearly move along a linear displacement direction perpendicular to the plane defined by the door frame 100 and move away from the door frame 100.

[0043] Finally, referring to Figure 5F as shown, the door panel 300 fixed to the door panel fixing assembly 210 rotates around the pivot mechanism 400, thereby realizing the state of opening the door panel 300 in the screen door device.

[0044] Thus, through the above product structure, the technical effect of ensuring the normal use of the screen door and extending the service life of the screen door can be achieved even after the screen door has been used for a long time. Furthermore, it solves the technical problem in the prior art that since the movement trajectory of the door panel 300 is arc-shaped when the existing screen door opens or closes the door panel 300, after the screen door has been used for a long time, the reed is prone to deformation, electromagnetic leakage may occur, affecting the normal use of the screen door, and in severe cases, it may even threaten the service life of the screen door.

[0045] Optionally, the door panel fixing assembly 200 includes: a first fixing assembly 210 and a second fixing assembly 220 respectively disposed on the left and right sides of the door frame 100, wherein the first side of the door panel 300 is rotatably fixed to the first fixing assembly 210 through a pivoting mechanism 400; and corresponding locking mechanisms 500 are respectively disposed on the second side of the door panel 300 and the second fixing assembly 220.

[0046] Specifically, referring to Figure 4 As shown, the door panel fixing assembly 200 includes a first fixing assembly 210 and a second fixing assembly 220. The first side of the door panel 300 is rotatably fixed to the first fixing assembly 210 through a pivoting mechanism 400, so that the door panel 300 can rotate about the pivoting mechanism 400 on the first fixing assembly 210 (i.e., opening or closing of the door panel 300).

[0047] Corresponding locking mechanisms 500 are respectively disposed on the second side of the door panel 300 and the second fixing assembly 220, so that when the door panel 300 rotates to close with the second fixing assembly 220, the locking mechanism 500 can lock the second fixing assembly 220 and the door panel 300 to prevent the second side of the door panel 300 from disengaging from the second fixing assembly 220 when the door panel fixing assembly 200 drives the door panel 300 to move.

[0048] Preferably, the pivoting mechanism 400 can be, for example, a door hinge.

[0049] Optionally, the upper part of the first side of the door frame 100 and the upper part of the first fixing assembly 210 are connected through a first sliding rail mechanism 610, and the lower part of the first side of the door frame 100 and the lower part of the first fixing assembly 210 are connected through a second sliding rail mechanism 620, wherein the first sliding rail mechanism 610 and the second sliding rail mechanism 620 extend along the linear displacement direction; and the upper part of the second side of the door frame 100 and the upper part of the second fixing assembly 220 are connected through a third sliding rail mechanism 630, and the lower part of the second side of the door frame 100 and the lower part of the second fixing assembly 210 are connected through a fourth sliding rail mechanism 640, wherein the third sliding rail mechanism 630 and the fourth sliding rail mechanism 640 extend along the linear displacement direction.

[0050] Specifically, referring to Figure 3 and Figure 4As shown, the upper part of the first side of the door frame 100 and the upper part of the first fixing component 210 are connected by a first sliding rail mechanism 610; the lower part of the first side of the door frame 100 and the lower part of the first fixing component 210 are connected by a second sliding rail mechanism 620; the upper part of the second side of the door frame 100 and the upper part of the second fixing component 220 are connected by a third sliding rail mechanism 630; the lower part of the second side of the door frame 100 and the lower part of the second fixing component 220 are connected by a fourth sliding rail mechanism 640. And among them, the first sliding rail mechanism 610, the second sliding rail mechanism 620, the third sliding rail mechanism 630 and the fourth sliding rail mechanism 640 all extend along the linear displacement direction perpendicular to the door frame 100.

[0051] Therefore, since the first sliding rail mechanism 610 and the second sliding rail mechanism 620 are provided between the door frame 100 and the first fixing component 210; the third sliding rail mechanism 630 and the fourth sliding rail mechanism 640 are provided between the door frame 100 and the second fixing component 220, after the first fixing component 210 and the second fixing component 220 obtain the driving force, they can move away from the door frame 100 (or move towards the door frame 100) by using the first sliding rail mechanism 610, the second sliding rail mechanism 620, the third sliding rail mechanism 630 and the fourth sliding rail mechanism 640.

[0052] Furthermore, since the door panel fixing component 200 in the present application is supported at four points by the first sliding rail mechanism 610, the second sliding rail mechanism 620, the third sliding rail mechanism 630 and the fourth sliding rail mechanism 640, the door panel 300 and the door panel fixing component 200 can be made more stable.

[0053] Optionally, it further includes: a driving system 700 and a transmission system 800, wherein the transmission system 800 is connected to the driving system 700 and the door panel fixing component 200, so that the driving system 700 can drive the door panel fixing component 200 to perform linear movement through the transmission system 800.

[0054] Specifically, Figure 6 is a schematic diagram of the driving system and the transmission system of the screen door device according to the embodiment of the present application. Refer to Figure 4 and Figure 6 As shown, the screen door device further includes a driving system 700 and a transmission system 800. Among them, the driving system 700 is connected to the transmission system 800, and the transmission system 800 is also connected to the door panel fixing component 200. Therefore, when the driving system 700 applies a driving force to the transmission system 800, the transmission system 800 can transmit the driving force to the door panel fixing component 200, so that the door panel fixing component 200 can perform a translational movement along the linear displacement direction relative to the door frame 100.

[0055] Preferably, the driving system 700 can be, for example, a motor.

[0056] Optionally, the drive system 800 includes: a first rotating shaft 810a disposed at the upper part of the door frame 100, connected to the drive system 700 through a first chain 810b, and a first gear 820a corresponding to the first fixing component 210 and a second gear 830a corresponding to the second fixing component 220 are provided on the first rotating shaft 810a; a first rack 820b disposed at the upper part of the first fixing component 210 and coupled to the first gear 820a; and a second rack 830b disposed at the upper part of the second fixing component 220 and coupled to the second gear 830a.

[0057] Specifically, referring to Figure 4 As shown, the drive system 800 includes a first rotating shaft 810a, wherein the first rotating shaft 810a is disposed at the upper part of the door frame 100 and is connected to the drive system 700 through a first chain 810b. In addition, a first gear 820a corresponding to the first fixing component 210 and a first rack 820b coupled to the first gear 820a are further provided on the upper part of the first rotating shaft 810a. Thus, when the drive system 700 applies a driving force to the drive system 800, the drive system 800 can transmit the driving force to the first gear 820a through the first chain 810b and the first rotating shaft 810a connected to the first chain 810b. Thus, after the first gear 820a receives the driving force, the first rack 820b coupled to the first gear 820a will move.

[0058] The drive system 800 is further provided with a second gear 830a and a second rack 830b. Among them, the second gear 830a and the second rack 830b are also disposed at the upper part of the second fixing component 220. Therefore, when the drive system 700 applies a driving force to the drive system 800, the drive system 800 can transmit the driving force to the second gear 830a through the first chain 810b and the first rotating shaft 810a connected to the first chain 810b. Thus, after the second gear 830a receives the driving force, the second rack 830b coupled to the second gear 830a will move.

[0059] In addition, since the first gear 820a and the first rack 820b receive the driving force, and at the same time, the second gear 830a and the second rack 830b also receive the driving force, the first gear 820a and the first rack 820b can move synchronously with the second gear 830a and the second rack 830a. Further, since the first gear 820a and the first rack 820b correspond to the first fixing component 210, and the second gear 830a and the second rack 830b correspond to the second fixing component 220, when the first gear 820a and the first rack 820b can move synchronously with the second gear 830a and the second rack 830a, the first fixing component 210 and the second fixing component 220 can also move synchronously.

[0060] Optionally, the transmission system 800 includes: a second rotating shaft 840a disposed at the lower part of the door frame 100, connected to the drive system 700 through a second chain 840b, and a third gear 850a corresponding to the first fixing component 210 is disposed on the second rotating shaft 840a; a third rack 850b disposed at the lower part of the first fixing component 210 and coupled to the third gear 850a.

[0061] Specifically, Figure 7 is a schematic diagram of the third gear and the third rack according to the embodiment of the present application. Refer to Figure 4 and Figure 7 As shown, the transmission system 800 includes a second rotating shaft 840a, wherein the second rotating shaft 840a is disposed at the lower part of the door frame 100 and is connected to the drive system 700 through a second chain 840b. In addition, a third gear 850a corresponding to the first fixing component 210 and a third rack 850b coupled to the third gear 850a are disposed on the second rotating shaft 840a. Thus, the driving force generated by the drive system 700 can be transmitted to the third gear 850a through the second chain 840b and the second rotating shaft 840a connected to the second chain 840b. After the third gear 850a receives the driving force, the third rack 850b coupled to the third gear 850a will move.

[0062] As can be seen from the above, when the drive system 700 starts to work, the third gear 850a and the third rack 850b also receive the driving force generated by the drive system 700 through the second chain 840b. Therefore, the first gear 820a and the first rack 820b, the second gear 830a and the second rack 830b, and the third gear 850a and the third rack 850b can move synchronously and work together.

[0063] In addition, an opening is provided at the position of the first fixing component 210 corresponding to the second rotating shaft 840a, so that the second rotating shaft 840a can just pass through the first fixing component 210.

[0064] Optionally, the transmission system 800 includes: a third rotating shaft 860a disposed at the lower part of the door frame 100, connected to the second rotating shaft 840a through a third chain 860b; a fourth rotating shaft 870a disposed at the lower part of the door frame 100, connected to the third rotating shaft 860a through a fourth chain 870b, and a fourth gear 880a corresponding to the second fixing component 220 is disposed on the fourth rotating shaft 870a; and a fourth rack 880b disposed at the lower part of the second fixing component 220 and coupled to the fourth gear 880a.

[0065] Specifically, refer to Figure 4As shown, the drive system 800 includes a third rotating shaft 860a, where the third rotating shaft 860a is disposed at the lower part of the door frame 100 and is connected to the second rotating shaft 840a through a third chain 860b. Thus, the driving force generated by the drive system 700 can be transmitted to the third rotating shaft 860a through the second rotating shaft 840a.

[0066] Furthermore, since the fourth rotating shaft 870a is disposed at the lower part of the door frame 100 and is connected to the third rotating shaft 860a through a fourth chain 870b, the driving force transmitted to the third rotating shaft 860a can be transmitted to the fourth rotating shaft 870a.

[0067] In addition, a fourth gear 880a corresponding to the second fixing component 220 is provided on the fourth rotating shaft 870a, and a fourth rack 880b coupled to the fourth gear 880a is further provided at the lower part of the second fixing component 220. Thus, when the fourth rotating shaft 870a is subjected to a driving force, the driving force can be transmitted to the fourth gear 880a, and the fourth rack 880b coupled to the fourth gear 880a will move.

[0068] In summary, since the first gear 820a and the first rack 820b, the second gear 830a and the second rack 830b, the third gear 850a and the third rack 850b, and the fourth gear 880a and the fourth rack 880b are respectively disposed at the 4 support points of the first fixing component 210 and the second fixing component 220 and can move synchronously, the first fixing component 210 and the second fixing component 220 can move synchronously. Thus, it can further ensure that the door knives 310, 320 provided in the door panel 300 are disengaged from the door knife slots 111, 112 (or inserted into the door knife slots 111, 112) in a translational manner.

[0069] Optionally, the drive system 700 includes: a motor 710, a transmission mechanism 720, and a manual rotation mechanism 730, where the output shafts of the motor 710 and the manual rotation mechanism 730 are respectively connected to the transmission mechanism 720; and the output shaft of the transmission mechanism 720 is respectively connected to the first chain 810b and the second chain 840b.

[0070] Specifically, in the first case, the drive system 700 includes a motor 710, a transmission mechanism 720, and a manual rotation mechanism 7۳0. Among them, the output shafts of the motor 710 and the manual rotation mechanism 730 are respectively connected to the transmission mechanism 720, and the output shaft of the transmission mechanism 720 is respectively connected to the first chain 810b and the second chain 840b.

[0071] Therefore, when the motor 710 can be used normally, the staff can use the motor 710 to drive the transmission mechanism 720. Thus, the transmission mechanism 720 transmits the power through the first chain 810b to the first fixing component 210, and transmits the driving force to the second fixing component 220 through the second chain 840b.

[0072] When the motor 710 cannot be used normally and the staff are locked in the shielding room, the staff can drive the transmission mechanism 720 by manually rotating the mechanism 730. Thus, the transmission mechanism 720 transmits the driving force to the first rotating shaft 810a through the first chain 810b and transmits the driving force to the second rotating shaft 840a through the second chain 840b, and ensures that the first fixing component 210 and the second fixing component 220 are disengaged from the door frame 100. Furthermore, the staff can smoothly exit from the shielding room.

[0073] Optionally, the output shaft of the transmission mechanism 720 is connected to a worm; the output shaft of the motor 710 is provided with a first worm gear coupled to the worm; the input shaft of the manual rotating mechanism 730 is connected to a second worm gear, and the second worm gear is coupled to the worm; and the manual rotating mechanism 730 further includes a crank, and the crank is connected to the end of the input shaft of the manual rotating mechanism 730 corresponding to the inside of the shielding room.

[0074] Specifically, as shown in Figure 4 the transmission mechanism 720 is connected to the motor 710 and the manual rotating mechanism 730 through a worm and worm gear mechanism respectively. The output shaft of the transmission mechanism 720 is connected to the worm, the output shaft of the motor 710 is connected to the first worm gear, and the first worm gear is coupled to the worm. Thus, the driving force generated by the motor 710 can be transmitted to the transmission mechanism 720 through the first worm gear and the worm connected to the first worm gear.

[0075] The output shaft of the transmission mechanism 720 is connected to the worm, the input shaft of the manual rotating mechanism 730 is connected to the second worm gear, and the second worm gear is coupled to the worm. Thus, the driving force generated by the manual rotating mechanism 730 can be transmitted to the transmission structure 720 through the second worm gear and the worm connected to the second worm gear.

[0076] In addition, a crank is further provided on the side of the manual rotating mechanism 730 corresponding to the inside of the shielding room, and the staff can transmit the generated driving force to the second worm gear by turning the crank.

[0077] Optionally, the drive system 70 includes: a motor 710, and the output shaft of the motor 710 is connected to the first chain 810b and the second chain 840b.

[0078] Specifically, in the second case, the drive system 700 includes a motor 710. The output shaft of the motor 710 is directly connected to the first chain 810b and the second chain 840b. Thus, the motor 710 can directly transmit the driving force to the first fixing component 210 and the second fixing component 220 through the first chain 810b and the second chain 840b.

[0079] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present disclosure. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0080] For the sake of convenience of description, spatial relative terms such as "above", "on top of", "on the upper surface", "upper" etc. may be used here to describe the spatial positional relationship between a device or feature shown in the drawings and other devices or features. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawing is inverted, the device described as "above" or "on top of" other devices or structures will then be positioned "below" or "beneath" the other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations are made for the spatial relative descriptions used here.

[0081] In the description of the present disclosure, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are generally based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present disclosure and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus cannot be construed as limiting the protection scope of the present disclosure; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0082] As described above, it is only the preferred specific implementation manner of the present application. However, the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
