Description

Technical Field

[0001] This application relates to the field of security access control technology, and in particular to a turnstile. Background Technology

[0002] To control the orderly passage of people, pedestrian access control gates are usually installed at entrances and exits. These gates, often simply called turnstiles, create passageways between gates or between gates and building structures. Currently, turnstiles are widely used in high-speed rail stations, subway systems, stadium ticket gate systems, long-distance bus station ticket gate systems, commercial building management systems, and tourist attraction ticket systems.

[0003] A typical turnstile consists of a gate panel and a drive shaft mechanism for controlling the rotation of the gate panel. To simplify the gate panel's fixation by eliminating visible screws, it is usually placed inside the rotating tube of the drive shaft mechanism for secure mounting. However, securing it internally with bolts presents challenges for disassembly and maintenance. While the gate panel can be removed by disassembling the entire drive shaft mechanism, this process is time-consuming, impacting customer experience and complicating on-site maintenance. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this application is to provide a gate with a door panel that is easy to disassemble and maintain.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] This application provides a turnstile, which includes a turnstile platform, a drive shaft mechanism, and a door panel. The drive shaft mechanism includes:

[0007] The rotating tube is a hollow tubular component with a notch for inserting a door panel into it.

[0008] The first clamping plate assembly is at least partially disposed inside the rotating tube. The first clamping plate assembly is relatively fixed to the rotating tube in the axial direction and is able to rotate around the axis of the rotating tube.

[0009] The second clamping plate assembly is disposed inside the rotating tube and is connected to the first clamping plate assembly via a clamping pin. The second clamping plate assembly has a degree of freedom of movement relative to the first clamping plate assembly along the axial direction of the clamping pin. The second clamping plate assembly is used to cooperate with the first clamping plate assembly to limit the door panel in the axial direction of the clamping pin. The clamping pin is also used to support the door panel.

[0010] The turnstile also includes a locking mechanism, which is at least partially located inside the rotating tube. One end of the locking mechanism abuts against the second clamping plate assembly or the clamping pin. The locking mechanism is used to push the second clamping plate assembly toward the first clamping plate assembly to clamp the door panel.

[0011] Furthermore, the locking mechanism includes a traction rope and a drive assembly for tightening the traction rope. The traction rope is at least partially inserted through the clamping pin. The end of the traction rope away from the drive assembly is provided with a limiting part that abuts against the clamping pin. When the drive assembly tightens the traction rope, the limiting part drives the second clamping plate assembly to clamp the door panel closer to the first clamping plate assembly through the clamping pin.

[0012] Furthermore, the drive shaft mechanism also includes an upper base and a lower base, which are used to close the rotating tube in the axial direction. The two ends of the first clamping plate assembly are respectively embedded in the upper base and the lower base. The lower base has a cable management groove that runs through the lower base along the axial direction of the rotating tube. The traction rope extends out of the rotating tube along the cable management groove and is connected to the drive assembly.

[0013] Furthermore, the drive shaft mechanism also includes a guide pin and an elastic element sleeved on the guide pin. The guide pin is distributed longitudinally on the upper and lower sides of the clamping pin, and the elastic element is located between the first clamping plate assembly and the second clamping plate assembly. When the drive assembly releases the traction rope, the elastic element is used to provide an elastic force to push the second clamping plate assembly to move away from the first clamping plate assembly.

[0014] Furthermore, the drive shaft mechanism also includes a retaining ring, which is sleeved on one end of the guide pin and the clamping pin away from the second clamping plate assembly. The retaining ring is used to prevent the clamping pin and / or the guide pin from disengaging from the first clamping plate assembly when the drive assembly releases the traction rope.

[0015] Furthermore, the number of clamping pins is set to at least two, the spacing between any two adjacent clamping pins is consistent, and the number of traction ropes configured on each clamping pin is the same.

[0016] Furthermore, the door panel has a groove for engaging the clamping pin. The groove includes a guide groove and a limiting groove that restricts the clamping pin from disengaging from the groove. The guide groove guides the door panel through the clamping pin along the extension direction of the guide groove. The guide groove and the limiting groove are connected.

[0017] This application also provides another type of turnstile, which includes a turnstile platform, a drive shaft mechanism, and a door panel, wherein the drive shaft mechanism includes:

[0018] The rotating tube is a hollow tubular component with a notch for inserting a door panel into it.

[0019] The first clamping plate assembly is at least partially disposed inside the rotating tube. The first clamping plate assembly is relatively fixed to the rotating tube in the axial direction and is able to rotate around the axis of the rotating tube.

[0020] The second clamping plate assembly is disposed inside the rotating tube and is connected to the first clamping plate assembly via a clamping pin. The second clamping plate assembly has a degree of freedom of movement relative to the first clamping plate assembly along the axial direction of the clamping pin. The second clamping plate assembly is used to cooperate with the first clamping plate assembly to limit the door panel in the axial direction of the clamping pin. The clamping pin is also used to support the door panel.

[0021] The hinge is located at the end of the guide pin opposite to the first clamping plate assembly via a pivot. The hinge has a rotational degree of freedom about the pivot axis. The end of the hinge opposite to the pivot abuts against the second clamping plate assembly.

[0022] The gate also includes a locking mechanism that is at least partially connected to the hinge and drives the hinge to rotate so that the hinge applies a force along the axial direction of the clamping pin to the second clamping plate assembly, which moves toward the first clamping plate assembly until it clamps the gate panel.

[0023] Furthermore, the locking mechanism includes a traction rope and a drive assembly for tightening the traction rope. The traction rope passes through the hinge longitudinally, and a limiting part abutting against the hinge is provided at the end of the traction rope away from the drive assembly. When the drive assembly tightens the traction rope, the limiting part pushes the second clamping plate assembly towards the first clamping plate assembly through the hinge to clamp the door panel.

[0024] Furthermore, the drive shaft mechanism also includes a guide pin, a snap ring, and an elastic element sleeved on the guide pin. The elastic element is located between the first clamping plate assembly and the second clamping plate assembly. When the drive assembly releases the traction rope, the elastic element provides an elastic force to push the second clamping plate assembly to move away from the first clamping plate assembly. The snap ring is sleeved on the end of the guide pin away from the first clamping plate assembly.

[0025] The gate provided in this application has a simple overall structure, fewer parts, and its gate panel is easier to disassemble and maintain. Attached Figure Description

[0033] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application.

[0034] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0035] It should be noted that in the embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0036] This application provides, as follows: Figure 1 The diagram illustrates a turnstile that can be applied to any location, such as residential areas, parking lots, and hospitals, to intercept and divert vehicle or pedestrian traffic. Several turnstiles, or turnstiles physically separated from building structures, form a passageway for pedestrian access.

[0037] like Figure 1 As shown, the turnstile includes a turnstile platform 100, a drive shaft mechanism 200, and a gate panel 300. The turnstile platform 100, as the main body of the turnstile, is fixed to the ground, and the aforementioned camera or camera is mounted on the turnstile platform 100. The turnstile also includes a drive motor and a rotating component. The drive motor drives the rotating component to rotate the drive shaft mechanism 200 around its axis, thereby controlling the opening and closing of the gate panel 300 to open or close the access channel.

[0038] like Figure 2 and Figure 3 As shown, in one implementation, the drive shaft mechanism 200 includes a rotating tube 21, a first clamping plate assembly 22, a second clamping plate assembly 23, and a clamping pin 24. The rotating tube 21 is a hollow tubular member, so that a receiving cavity 211 is formed inside the rotating tube 21, and a notch 212 is opened on the side wall of the rotating tube 21, which allows the door panel 300 to be inserted into the receiving cavity 211 of the rotating tube 21.

[0039] For example, the first clamping plate assembly 22 is at least partially disposed within the receiving cavity 211 of the rotating tube 21. The first clamping plate assembly 22 is relatively fixed to the rotating tube 21 in the axial direction and is capable of rotating around the axis of the rotating tube 21. The drive shaft mechanism 200 includes an upper base 291 and a lower base 292, which are respectively fixedly connected to the upper and lower openings of the rotating tube 21, thereby closing the receiving cavity 211 of the rotating tube 21 in the vertical direction. The fixed connection method includes, but is not limited to, interference fit, threaded connection, welding, etc.

[0040] In this embodiment, the upper base 291 and / or the lower base 292 are connected to the aforementioned rotating component. The two ends of the first clamping plate assembly 22 extending along the axial direction of the rotating tube 21 are respectively fitted into the upper base 291 and the lower base 292. When the drive motor drives the upper base 291 and / or the lower base 292 to rotate through the rotating component, it drives the first clamping plate assembly 22 to rotate synchronously.

[0041] Furthermore, when the drive motor drives the upper base 291 and / or the lower base 292 to rotate through the rotating component, the rotating tube 21, which is fixedly connected to the upper base 291 and the lower base 292, rotates synchronously.

[0042] For example, a second clamping plate assembly 23 is disposed in the receiving cavity 211. The second clamping plate assembly 23 is connected to the first clamping plate assembly 22 via a clamping pin 24. The second clamping plate assembly 23 has a degree of freedom of movement relative to the first clamping plate assembly 22 along the axial direction of the clamping pin 24. The second clamping plate assembly 23 is used to cooperate with the first clamping plate assembly 22 to limit the door panel 300 in the axial direction of the clamping pin 24. The clamping pin 24 is also used to support the door panel 300.

[0043] Specifically, the second clamping plate assembly 23 is arranged opposite to the first clamping plate assembly 22, and the extension direction of the second clamping plate assembly 23 is parallel to the extension direction of the first clamping plate assembly 22, so as to avoid the second clamping plate assembly 23 and the first clamping plate assembly 22 occupying too much space in the receiving cavity 211, so as to make the overall structure of the drive shaft mechanism 200 more compact.

[0044] In some examples, the clamping pin 24 has a first end and a second end facing away from each other. The second end of the clamping pin 24 passes sequentially through the second clamping plate assembly 23 and the first clamping plate assembly 22 until the first end of the clamping pin 24 abuts against the side end face of the second clamping plate assembly 23 facing away from the first clamping plate assembly 22. When the clamping pin 24 passes through the first clamping plate assembly 22, the clamping pin 24 has a degree of freedom of movement relative to the first clamping plate assembly 22 along its own axial direction. This allows the second clamping plate assembly 23 to move closer to or further away from the first clamping plate assembly 22 along the axial direction of the clamping pin 24.

[0045] It should be noted that the first end of the clamping pin 24 is the pin head, which is the protruding part at the top and the main part of the hammering. It is usually hemispherical or flattened round. The second end of the clamping pin 24 is the pin tail, which is the end of the clamping pin 24 and the part that is not fixed.

[0046] As an alternative implementation, the rotating pipe 21 and the gate 100 remain relatively fixed in any direction. The rotating pipe 21 is circumferentially fitted around the first clamping plate assembly 22, and there are gaps distributed around the upper base 291 between the rotating pipe 21 and the upper base 291 to avoid wear between the rotating pipe 21 and the upper base 291, or between the rotating pipe 21 and the lower base 292. The drive motor drives the upper base 291 to rotate around the axis of the rotating pipe 21 by driving the rotating component. Since the first clamping plate assembly 22 is embedded in the upper base 291, the first clamping plate assembly 22 and the upper base 291 rotate synchronously, thereby controlling the opening and closing of the gate panel 300 to open or close the access channel.

[0047] It should be noted that, since the rotary tube 21 and the gate platform 100 are kept relatively fixed in any direction, in order to avoid interference between the gate panel 300 and the notch 212 of the rotary tube 21, when viewed along the axis of the rotary tube 21, the central angle corresponding to the notch 212 is greater than or equal to the maximum deflection angle of the gate panel 300 around the axis of the rotary tube 21.

[0048] like Figure 3 As shown in this embodiment, the turnstile further includes a locking mechanism 400, which is disposed at the bottom of the turnstile platform 100 and is at least partially disposed inside the rotating tube 21, thereby connecting to the second clamping plate assembly 23 or the clamping pin 24. The locking mechanism 400 can apply a force to the second clamping plate assembly 23 toward the first clamping plate assembly 22, thereby pushing the second clamping plate assembly 23 to clamp the door panel 300 toward the first clamping plate assembly 22.

[0049] Specifically, the locking mechanism 400 includes a traction rope 41 and a drive assembly 42. The two ends of the traction rope 41 are connected to the clamping pin 24 and the drive assembly 42, respectively. When the drive assembly 42 pulls the traction rope 41, the first end of the clamping pin 24 abuts against the second clamping plate assembly 23, causing the second clamping plate assembly 23 to move closer to the first clamping plate assembly 22. This causes the first clamping plate assembly 22 and the second clamping plate assembly 23 to clamp the door panel 300, preventing the door panel 300 from falling off the drive shaft mechanism 200. When the drive assembly 42 releases the traction rope 41, the second clamping plate assembly 23 gains a degree of freedom of movement away from the first clamping plate assembly 22, allowing the door panel 300 to be removed from the installation gap between the first clamping plate assembly 22 and the second clamping plate assembly 23.

[0050] For example, the drive component 42 is a motor that tightens or loosens the traction rope 41.

[0051] Optionally, the drive assembly 42 can also be configured as a quick clamp, with one end fixed and the other end connected to the traction rope 41. When the quick clamp closes, it tightens the traction rope 41, causing the first end of the clamping pin 24 to abut against the second clamping plate assembly 23, and moving the second clamping plate assembly 23 towards the first clamping plate assembly 22, thereby clamping the door panel 300 between the first clamping plate assembly 22 and the second clamping plate assembly 23. When the quick clamp opens, it releases the traction rope 41, allowing the second clamping plate assembly 23 to have a degree of freedom of movement away from the first clamping plate assembly 22.

[0052] Optionally, the drive assembly 42 can also be configured as a linkage, with one end connected to the traction rope 41 and the other end rotatably mounted on the gate platform 100. When the linkage deflects to one side, it tightens the traction rope 41, causing the first end of the clamping pin 24 to abut against the second clamping plate assembly 23, and driving the second clamping plate assembly 23 to move closer to the first clamping plate assembly 22, thereby clamping the gate panel 300 between the first clamping plate assembly 22 and the second clamping plate assembly 23. When the linkage deflects to the other side, it releases the traction rope 41, allowing the second clamping plate assembly 23 to have a degree of freedom of movement away from the first clamping plate assembly 22.

[0053] It should be noted that although the drive assembly 42 includes the motor, quick clamp and connecting rod mentioned above, any structure that can tighten and loosen the traction rope 41 can be considered as the technical solution claimed in this application.

[0054] In this embodiment, the locking mechanism 400 operates the second clamping plate assembly 23 to engage with the first clamping plate assembly 22, thereby clamping or releasing the door panel 300. This solves the problem in related technologies where the door panel 300 is difficult to replace. Furthermore, the above solution causes less wear on the drive shaft mechanism 200 and related components, and its simple structure makes it easier to maintain and replace the drive shaft mechanism 200.

[0055] like Figure 4 As shown, in one implementation, the traction rope 41 is at least partially inserted into the clamping pin 24, and a limiting portion 411 is formed at the end of the traction rope 41 facing away from the drive assembly 42. When the drive assembly 42 tightens the traction rope 41, the limiting portion 411 abuts against the first end of the clamping pin 24 along the axial direction, and the clamping pin 24 drives the second clamping plate assembly 23 to clamp the door panel 300 closer to the first clamping plate assembly 22. In the above arrangement, the direction of the traction force applied by the traction rope 41 to the clamping pin 24 is substantially parallel to the axial direction of the clamping pin 24, improving the stability of the clamping of the door panel 300 by the first clamping plate assembly 22 and the second clamping plate assembly 23.

[0056] Optionally, the traction rope 41 can also be fixedly connected to the second end of the clamping pin 24. When the drive assembly 42 pulls the traction rope 41, the traction force applied by the traction rope 41 to the clamping pin 24 drives the second clamping plate assembly 23 to clamp the door panel 300 in a direction closer to the first clamping plate assembly 22.

[0057] In this embodiment, the lower base 292 has a cable management groove 292a that extends through the lower base 292 along the axial direction of the rotating tube 21. The traction rope 41 extends out of the rotating tube 21 along the cable management groove 292a and connects to the drive assembly 42. This avoids the traction rope 41 being exposed and causing wear. Since the traction rope 41 extends substantially along the axial direction of the rotating tube 21, the cable management groove 292a reduces the bending of the traction rope 41, thereby reducing the frictional force that the drive assembly 42 needs to overcome when pulling the traction rope 41, and further reducing the wear of the locking mechanism 400 components.

[0058] As an optional implementation, the number of clamping pins 24 is set to at least two. When the door panel 300 enters the receiving cavity 211 along the notch 212, the door panel 300 at least partially extends into the mounting gap between the first clamping plate assembly 22 and the second clamping plate assembly 23, and is mounted on the clamping pins 24. The door panel 300 is supported by at least two clamping pins 24 in the extending direction of the first clamping plate assembly 22, thereby improving the stability of the door panel 300 when mounted on the clamping pins 24.

[0059] More preferably, the multiple clamping pins 24 are evenly arranged along the extension direction of the first clamping plate assembly 22, that is, the interval between any two adjacent clamping pins 24 is consistent. The number of traction ropes 41 configured on each clamping pin 24 is the same, so that the force exerted by the multiple clamping pins 24 on the second clamping plate assembly 23 is basically consistent, avoiding the door panel 300 from shaking or deforming due to excessive pressure when the first clamping plate assembly 22 and the second clamping plate assembly 23 clamp the door panel 300.

[0060] like Figure 5 As shown in this embodiment, the drive shaft mechanism 200 further includes guide pins 25 and elastic members 26 sleeved on the guide pins 25. The guide pins 25 are distributed on the upper and lower sides of the clamping pins 24. When the door panel 300 is mounted on the clamping pins 24, the guide pins 25 distributed on the upper and lower sides of the clamping pins 24 can avoid the door panel 300 in the longitudinal direction, thus avoiding assembly interference between the components. The longitudinal direction is basically parallel to the axial direction of the rotating tube 21.

[0061] Specifically, the elastic element 26 is disposed between the first clamping plate assembly 22 and the second clamping plate assembly 23. When the drive assembly 42 releases the traction rope 41, the elastic element 26 is used to provide an elastic force to push the second clamping plate assembly 23 to move away from the first clamping plate assembly 22.

[0062] For example, the guide pin 25 has a first end and a second end facing away from each other. The second end of the guide pin 25 passes sequentially through the second clamping plate assembly 23 and the first clamping plate assembly 22 until the first end of the guide pin 25 abuts against the side end face of the second clamping plate assembly 23 facing away from the first clamping plate assembly 22. When the guide pin 25 passes through the first clamping plate assembly 22, the guide pin 25 has a degree of freedom of movement relative to the first clamping plate assembly 22 along its own axial direction. This allows the second clamping plate assembly 23 to move closer to or further away from the first clamping plate assembly 22 along the axial direction of the guide pin 25.

[0063] It should be noted that the first end of the guide pin 25 is the pin head, and the second end of the guide pin 25 is the pin tail.

[0064] For example, the elastic element 26 is a compression spring. When the drive assembly 42 tightens the traction rope 41, the two ends of the elastic element 26 abut against the first clamping plate assembly 22 and the second clamping plate assembly 23, respectively. When the drive assembly 42 releases the traction rope 41, the compressed elastic element 26 applies a force to the second clamping plate assembly 23 away from the first clamping plate assembly 22, thereby pushing the second clamping plate assembly 23 to move away from the first clamping plate assembly 22, thus making it possible for the door panel 300 to be removed from the installation gap between the first clamping plate assembly 22 and the second clamping plate assembly 23.

[0065] Optionally, the elastic element 26 can also be a disc spring. Disc springs can withstand extremely high loads within a small space. Compared with other types of elastic elements 26, disc springs have a larger deformation energy per unit volume. They have good buffering and shock absorption capabilities, especially when used in a stacked combination, where the absorption of impact and dissipation of energy are more significant due to surface frictional resistance.

[0066] There are no excessive restrictions on the type of elastic element 26. Any elastic element 26 that can push or pull the second clamping plate assembly 23 to move away from the first clamping plate assembly 22 when the drive assembly 42 is released from the traction rope 41 is considered to be within the scope of protection claimed in the application.

[0067] like Figure 5 As shown in this embodiment, the drive shaft mechanism 200 further includes a retaining ring 27, which is detachably sleeved on the second end of the guide pin 25 and the clamping pin 24. The retaining ring 27 is used to prevent the clamping pin 24 and / or the guide pin 25 from disengaging from the first clamping plate assembly 22 when the drive assembly 42 releases the traction rope 41.

[0068] Specifically, the first clamping plate assembly 22 is provided with a plurality of limiting holes 221, and the clamping pin 24 and the guide pin 25 pass through the limiting holes 221 of the first clamping plate assembly 22, thereby limiting the radial displacement of the clamping pin 24 and the guide pin 25.

[0069] It should be noted that the outer diameter of the snap ring 27 is at least greater than the inner diameter of the limiting hole 221.

[0070] like Figure 5 As shown, as an optional implementation, the door panel 300 has a groove 31 for engaging the clamping pin 24. The groove 31 includes a guide groove 311 and a limiting groove 312. The guide groove 311 extends along a first direction, and the limiting groove 312 extends along a second direction. The guide groove 311 guides the door panel 300 to pass through the clamping pin 24 along the first direction, and the limiting groove 312 restricts the clamping pin 24 from disengaging from the groove 31. The guide groove 311 and the limiting groove 312 are connected.

[0071] It should be noted that the angle between the first direction and the second direction is greater than or equal to 0° and less than or equal to 180°.

[0072] like Figure 6 As shown, this application also provides another embodiment, in which the drive shaft mechanism 200 includes a rotating tube 21, a first clamping plate assembly 22, a second clamping plate assembly 23, a clamping pin 24, and a hinge 28. The rotating tube 21 is a hollow tubular component, and a notch 212 is provided on the rotating tube 21 for the gate plate 300 of the gate machine to be inserted into the interior of the rotating tube 21.

[0073] For example, the first clamping plate assembly 22 is at least partially disposed within the receiving cavity 211 of the rotating tube 21. The first clamping plate assembly 22 is relatively fixed to the rotating tube 21 in the axial direction and is capable of rotating around the axis of the rotating tube 21. The drive shaft mechanism 200 includes an upper base 291 and a lower base 292, which are respectively fixedly connected to the upper and lower openings of the rotating tube 21, thereby closing the receiving cavity 211 of the rotating tube 21 in the vertical direction. The fixed connection method includes, but is not limited to, interference fit, threaded connection, welding, etc.

[0074] In this embodiment, the upper base 291 and / or the lower base 292 are connected to the aforementioned rotating component. The two ends of the first clamping plate assembly 22 extending along the axial direction of the rotating tube 21 are respectively fitted into the upper base 291 and the lower base 292. When the drive motor drives the upper base 291 and / or the lower base 292 to rotate through the rotating component, it drives the first clamping plate assembly 22 to rotate synchronously.

[0075] Furthermore, when the drive motor drives the upper base 291 and / or the lower base 292 to rotate through the rotating component, the rotating tube 21, which is fixedly connected to the upper base 291 and the lower base 292, rotates synchronously.

[0076] For example, a second clamping plate assembly 23 is disposed in the receiving cavity 211. The second clamping plate assembly 23 is connected to the first clamping plate assembly 22 via a clamping pin 24. The second clamping plate assembly 23 has a degree of freedom of movement relative to the first clamping plate assembly 22 along the axial direction of the clamping pin 24. The second clamping plate assembly 23 is used to cooperate with the first clamping plate assembly 22 to limit the door panel 300 in the axial direction of the clamping pin 24. The clamping pin 24 is also used to support the door panel 300.

[0077] The clamping pin 24 passes through the first clamping plate assembly 22 and the second clamping plate assembly 23 in sequence, and the first end of the clamping pin 24 abuts against the side end face of the first clamping plate assembly 22 away from the second clamping plate assembly 23.

[0078] like Figure 6 As shown, in one implementation, the hinge 28 is rotatably disposed at the second end of the clamping pin 24 via a pivot and abuts against the end face of the second clamping plate assembly 23. Specifically, the hinge 28 includes a rotating portion 281 and an abutting portion 282. The rotating portion 281 forms a gap into which the second end of the clamping pin 24 can be inserted. The pivot passes through the rotating portion 281 and the second end of the clamping pin 24, so that the hinge 28 can rotate relative to the second end of the clamping pin 24. The abutting portion 282 is the other end opposite to the rotating portion 281, and the hinge 28 abuts against the second clamping plate assembly 23 through the abutting portion 282.

[0079] Furthermore, the door panel 300 is disposed between the first clamping plate assembly 22 and the second clamping plate assembly 23, and is mounted on the clamping pin 24.

[0080] like Figure 6 As shown, in one implementation, the drive shaft mechanism 200 also includes a guide pin 25, a snap ring 27, and an elastic element 26 sleeved on the guide pin 25. The elastic element 26 is located between the first clamping plate assembly 22 and the second clamping plate assembly 23. When the drive assembly 42 releases the traction rope 41, the elastic element 26 is used to provide an elastic force to push the second clamping plate assembly 23 to move away from the first clamping plate assembly 22.

[0081] A retaining ring 27 is fitted onto the tail of the guide pin 25 to prevent the guide pin 25 from detaching from the second clamping plate assembly 23 along its own axis. Since the tail of the clamping pin 24 has a hinge 28, the clamping pin 24 is axially limited to prevent it from detaching from the second clamping plate assembly 23 along its own axis.

[0082] like Figure 7As shown, the two ends of the traction rope 41 are connected to the drive assembly 42 and the hinge 28, respectively. The drive assembly 42 pulls the traction rope 41 so that the hinge 28 rotates to abut against the second clamping plate assembly 23 and pushes the second clamping plate assembly 23 to move closer to the first clamping plate assembly 22 to press against the door panel 300, or the drive assembly 42 releases the traction rope 41, and the second clamping plate assembly 23 has a degree of freedom of movement in the direction away from the first clamping plate assembly 22.

[0083] For example, the traction rope 41 passes through the hinge 28 in the longitudinal direction, and a limiting part 411 is provided at the end of the traction rope 41 away from the drive assembly 42. When the drive assembly 42 pulls the traction rope 41, the traction rope 41 applies a traction force to the hinge 28 through the limiting part 411, so that the abutment part 282 of the hinge 28 abuts against the second clamping plate assembly 23, and drives the second clamping plate assembly 23 to move closer to the first clamping plate assembly 22, thereby clamping the door panel 300 disposed between the first clamping plate assembly 22 and the second clamping plate assembly 23.

[0084] Understandably, when the drive assembly 42 detaches from the traction rope 41, the traction force exerted by the traction rope 41 on the hinge 28 disappears, and the second clamping plate assembly 23 has a degree of freedom of movement in the direction away from the first clamping plate assembly 22.

[0085] It should be noted that the number of hinges 28 is the same as the number of traction ropes 41, and the number of traction ropes 41 configured on each hinge 28 is the same. This ensures that the forces exerted by the multiple hinges 28 on the second clamping plate assembly 23 are basically consistent, preventing the door panel 300 from shaking or deforming due to excessive pressure when the first clamping plate assembly 22 and the second clamping plate assembly 23 clamp the door panel 300.

[0086] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
