Description

Technical Field

[0001] This utility model relates to the field of automatic door technology, and in particular to an arc-shaped opening and closing door. Background Technology

[0002] With the development of technology and people's increasing pursuit of quality of life, various automated door systems have been widely used in construction, performances, exhibitions, and other fields. Among them, the arc-shaped opening and closing door is particularly favored by stage performances and large-scale events due to its unique opening and closing mechanism and beautiful appearance. However, existing arc-shaped opening and closing door systems have some technical bottlenecks that limit their reliability and stability in practical applications.

[0003] First, the existing arc-shaped opening door structure is quite complex, involving numerous parts and connectors. This complex structure not only increases manufacturing costs but also makes door assembly and maintenance difficult. In practice, due to the large number of parts, a malfunction in any small component can cause the entire system to fail, thus increasing the difficulty and cost of maintenance.

[0004] Secondly, due to their complex structure, existing arc-shaped door systems often struggle to achieve precise control during opening and closing. This imprecise control not only affects the door's aesthetics but, more importantly, can lead to jamming or asynchrony during opening and closing, thus impacting the performance and the audience's experience.

[0005] Furthermore, the existing circular arc-shaped door system suffers from poor operational stability. Under high-intensity operating conditions, such as continuous performances or frequent opening and closing operations, the system is prone to malfunctions. These malfunctions may be caused by wear and tear on components, loose connections, or instability in the control system. Once a malfunction occurs, it will not only affect the normal progress of the performance but may also threaten the safety of performers and audience members.

[0006] Because existing curved door systems lack sufficient flexibility and adaptability in their design, they are difficult to adapt to different venues and environmental requirements. This means that additional adjustments and modifications may be needed for different performance venues, which undoubtedly increases usage costs and time.

[0007] In summary, existing arc-shaped door systems have significant shortcomings in terms of structural design, precise control, operational stability, and adaptability. These problems not only affect the system's performance but also limit its application in a wider range of fields.

[0008] Therefore, there is an urgent need to develop a new type of arc-shaped opening and closing door system that is simple in structure, precise in control, stable in operation, and highly adaptable. This is of great practical significance for improving performance effects, ensuring safety, and reducing maintenance costs. Utility Model Content

The track is circular. The left door body and the right door body are both slidably disposed below the track. The drive assembly is disposed along the center line of the track in the front-back direction.

[0011] The left and right sliding components are symmetrically arranged on the track about the drive component;

[0012] The left pull-out assembly is arranged along the left side of the track, and both ends of the left pull-out assembly are connected to the output end of the drive assembly. The left pull-out assembly is connected to the left door body. The right pull-out assembly is arranged along the right side of the track, and both ends of the right pull-out assembly are connected to the output end of the drive assembly. The right pull-out assembly is connected to the right door body.

[0013] Both the left and right pull-out components are annular, and the output end of the drive component can reciprocate along the centerline of the track in the forward and backward directions.

[0014] Furthermore, the output end of the drive assembly is a telescopic rod, both ends of the left pull assembly are connected to the left side of the telescopic rod, and both ends of the right pull assembly are connected to the right side of the telescopic rod.

[0015] Furthermore, the drive assembly includes a motor, a cylinder, and the telescopic rod connected in sequence, with the motor, the cylinder, and the telescopic rod all arranged along the center line of the track in the front-rear direction.

[0016] Furthermore, the drive assembly also includes a fixing member connected to the end of the telescopic rod, the fixing member having a plurality of fixing holes, the two ends of the left pull assembly and the right pull assembly being connected to the fixing holes.

[0017] Furthermore, the number of fixing holes is four, with the two ends of the left pull-out assembly fixed in the two fixing holes on the left side of the fixing member, and the two ends of the right pull-out assembly fixed in the two fixing holes on the right side of the fixing member.

[0018] Furthermore, the track is provided with several pulleys, and both the left pull-out assembly and the right pull-out assembly are connected to the track via pulleys.

[0019] Furthermore, the front end of the track is symmetrically provided with two first pulleys about the drive component, the rear end of the track is symmetrically provided with two fourth pulleys about the drive component, and the middle part of the track is also provided with a second pulley, which is positioned between the first pulleys and the fourth pulleys. One end of the left pull-out component is connected to the output end of the drive component, and the other end of the left pull-out component passes through the first pulley, the second pulley, and the fourth pulley in sequence before connecting to the output end of the drive component. One end of the right pull-out component is connected to the output end of the drive component, and the other end of the right pull-out component passes through the first pulley, the second pulley, and the fourth pulley in sequence before connecting to the output end of the drive component.

[0020] Furthermore, the track is also equipped with a third pulley, which is positioned between the second pulley and the fourth pulley;

[0021] One end of the left pull-out assembly is connected to the output end of the drive assembly, and the other end of the left pull-out assembly passes through the first pulley, the second pulley, the third pulley, and the fourth pulley in sequence before being connected to the output end of the drive assembly; one end of the right pull-out assembly is connected to the output end of the drive assembly, and the other end of the right pull-out assembly passes through the first pulley, the second pulley, the third pulley, and the fourth pulley in sequence before being connected to the output end of the drive assembly.

[0022] Furthermore, both the left and right pull-out components are made of steel wire rope.

[0023] Furthermore, the arc-shaped opening and closing door also includes a controller, which is electrically connected to the drive assembly.

[0024] The arc-shaped opening and closing door provided by this utility model, through simplified design, features a drive assembly positioned along the track centerline in a forward and backward direction. The output end of the drive assembly reciprocates along the track centerline in this direction. A left-pull-out assembly and a right-pull-out assembly are symmetrically positioned on the left and right sides of the drive assembly. Since both ends of the left-pull-out assembly are connected to the left side of the drive assembly output end and are ring-shaped, and both ends of the right-pull-out assembly are connected to the right side of the drive assembly output end and are also ring-shaped, the reciprocating motion of the drive assembly output end allows the left and right pull-out assemblies to rotate along the track, thereby pulling the left door body clockwise and the right door body counterclockwise, completing the opening and closing of the left and right doors. The arc-shaped opening and closing door provided by this utility model operates reliably, reducing problems of inaccurate opening and closing actions and poor operational stability caused by component failures, thus lowering the risk of door system malfunctions preventing normal opening and closing during performances and large-scale events. Furthermore, its ability to flexibly adapt to different venues and environmental requirements further reduces the additional adjustment and modification costs caused by venue changes. At the same time, it provides more reliable and stable opening and closing movements, enhancing the performance effect while ensuring the safety of performers and audiences.

[0044] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0045] Please see Figures 1 to 5 The arc-shaped opening and closing door provided in this embodiment of the utility model includes a track 400, a left door body 100, a right door body 200, a drive assembly 300, a left pull assembly 500, and a right pull assembly 600. The track 400 is set in a horizontal plane, and the projection shape of the track 400 in the horizontal plane is circular. The track 400 plays a guiding role for the left door body 100 and the right door body 200. The left door body 100 and the right door body 200 are both slidably set below the track 400 in the vertical direction, and the left door body 100 and the right door body 200 are symmetrically arranged about the center line of the track 400 in the front-back direction. The drive assembly 300 is set along the center line of the track 400 in the front-back direction.

[0046] The left pull-out assembly 500 and the right pull-out assembly 600 are symmetrically arranged on the track 400 about the drive assembly 300, and are used to control the movement of the left door 100 and the right door 200, respectively.

[0047] The left pull-out assembly 500 is arranged along the left side of the track 400, and both ends of the left pull-out assembly 500 are connected to the output end of the drive assembly 300. The left pull-out assembly 500 is connected to the left door 100. The right pull-out assembly 600 is arranged along the right side of the track 400, and both ends of the right pull-out assembly 600 are connected to the output end of the drive assembly 300. The right pull-out assembly 600 is connected to the right door 200.

[0048] Both the left pull-out assembly 500 and the right pull-out assembly 600 are ring-shaped, and the output end of the drive assembly 300 can reciprocate along the center line of the track 400 in the forward and backward directions.

[0049] The arc-shaped opening and closing door provided by this utility model, through simplified design, has a drive assembly 300 arranged along the front and back directions at the center line of the track 400. The output end of the drive assembly 300 can reciprocate along the front and back directions at the center line of the track 400. A left pull assembly 500 and a right pull assembly 600 are symmetrically arranged on the left and right sides of the drive assembly 300. Since both ends of the left pull assembly 500 are connected to the left side of the output end of the drive assembly 300 and the left pull assembly 500 is ring-shaped, and both ends of the right pull assembly 600 are connected to the right side of the output end of the drive assembly 300 and the right pull assembly 600 is ring-shaped, the reciprocating motion of the output end of the drive assembly 300 can make the left pull assembly 500 and the right pull assembly 600 rotate along the track 400, thereby pulling the left door 100 to move in a clockwise direction and pulling the right door 200 to move in a counterclockwise direction, thus completing the opening and closing of the left and right doors. The arc-shaped opening and closing door provided by this utility model is reliable in operation, reducing problems such as inaccurate opening and closing actions and poor operational stability caused by component failures. This lowers the risk of door system malfunctions preventing normal opening and closing during performances and large-scale events. The arc-shaped opening and closing door provided by this utility model can flexibly adapt to different venue and environmental requirements, further reducing additional adjustment and modification costs caused by venue changes. At the same time, it provides more reliable and stable opening and closing actions, enhancing the performance effect while ensuring the safety of performers and audiences.

[0050] Please see Figure 5 In an optional embodiment of this utility model, the output end of the drive assembly 300 is a telescopic rod 330. The travel of the telescopic rod 330 is controllable, thereby enabling smooth and precise movement of the arc-shaped opening and closing door. Both ends of the left pull-out assembly 500 are connected to the left side of the telescopic rod 330, and both ends of the right pull-out assembly 600 are connected to the right side of the telescopic rod 330. Please participate. Figure 2 and Figure 4 The two ends of the left pull-out assembly 500 and the two ends of the right pull-out assembly 600 are respectively connected to the left and right sides of the telescopic rod 330 to avoid interference. This prevents the left pull-out assembly 500 and the right pull-out assembly 600 from getting tangled or interfering when the drive assembly 300 moves, and further ensures the smooth operation of the arc-shaped opening and closing door.

[0051] Please see Figure 5 Furthermore, the drive assembly 300 includes a motor 310, a cylinder 320, and a telescopic rod 330 connected in sequence. The motor 310, cylinder 320, and telescopic rod 330 are all arranged along the center line of the track 400 in the front-back direction. The motor 310 and cylinder 320 work together to control the movement of the telescopic rod 330, further ensuring that the stroke of the telescopic rod 330 is fixed and realizing the precise opening and closing of the arc-shaped door.

[0052] In an optional embodiment of this utility model, the drive assembly 300 further includes a fixing member 340 connected to the end of the telescopic rod 330. The fixing member 340 is provided with a plurality of fixing holes 341, and the two ends of the left pull assembly 500 and the right pull assembly 600 are respectively fixed in the fixing holes 341.

[0053] Specifically, such as Figure 5 As shown, there are four fixing holes 341. The two ends of the left pull-out assembly 500 are respectively fixed in the two fixing holes 341 on the left side of the fixing member 340, and the two ends of the right pull-out assembly 600 are respectively fixed in the two fixing holes 341 on the right side of the fixing member 340.

[0054] Please see Figure 2 and Figure 4 In an optional embodiment of this utility model, the track 400 is provided with a plurality of pulleys, and both the left pull-out assembly 500 and the right pull-out assembly 600 are connected to the track 400 via pulleys. By providing pulleys, the friction between the left pull-out assembly 500 and the right pull-out assembly 600 and the track 400 is reduced, thereby facilitating the sliding of the left pull-out assembly 500 and the right pull-out assembly 600, improving the stability of the system's motion, and extending the lifespan of the left pull-out assembly 500 and the right pull-out assembly 600.

[0055] Specifically, the front end of the track 400 is symmetrically provided with two first pulleys about the drive component 300, the rear end of the track 400 is symmetrically provided with two fourth pulleys about the drive component 300, and the middle part of the track 400 is also provided with two second pulleys. The two second pulleys are respectively located between the first pulleys and fourth pulleys on the left and right sides of the track 400. One end of the left pull-out component 500 is connected to the output end of the drive component 300, and the other end of the left pull-out component 500 passes through the first pulley, the second pulley and the fourth pulley in sequence and then connects to the output end of the drive component 300. The left pull-out component 500 is in a ring shape when connected. One end of the right pull-out component 600 is connected to the output end of the drive component 300, and the other end of the right pull-out component 600 passes through the first pulley, the second pulley and the fourth pulley in sequence and then connects to the output end of the drive component 300. The right pull-out component 600 is in a ring shape when connected.

[0056] Furthermore, the track 400 is equipped with two third pulleys, which are respectively located between the second and fourth pulleys on the left and right sides of the track 400. By setting the third pulleys, a better guiding effect can be achieved for the pull-out assembly.

[0057] For details, please refer to the diagram and... Figure 4For ease of description, taking the left pull-out component 500 as an example, one end of the left pull-out component 500 is connected to the output end of the drive component 300, and the other end of the left pull-out component 500 passes through the first left pulley 410, the second left pulley 420, the third left pulley 430 and the fourth left pulley 440 in sequence before connecting to the output end of the drive component 300. The left pull-out component 500 is in a ring shape when connected. Symmetrical to the left, one end of the right pull-out component 600 is connected to the output end of the drive component 300, and passes through the first right pulley, the second right pulley, the third right pulley and the fourth right pulley in sequence before connecting to the output end of the drive component 300. The right pull-out component 600 is in a ring shape when connected.

[0058] Specifically, for ease of description, taking the left pull-out assembly 500 as an example, the left pull-out assembly 500 includes a first rope segment 510 located between the fixing member 340 and the left first pulley 410, a second rope segment 520 located between the left first pulley 410 and the left second pulley 420, a third rope segment 530 located between the left second pulley 420 and the left third pulley 430, a fourth rope segment 540 located between the left third pulley 430 and the left fourth pulley 440, and a fifth rope segment 550 located between the left fourth pulley 440 and the fixing member 340. When the telescopic rod 33... When the device 0 moves forward along the centerline of track 400, the fixing member 340 pulls the fifth rope segment 550, the fifth rope segment 550 pulls the fourth rope segment 540, the fourth rope segment 540 pulls the third rope segment 530, the third rope segment 530 pulls the second rope segment 520, and the second rope segment 520 pulls the first rope segment 510. Therefore, the left door 100 connected to the left pull-out assembly 500 will rotate clockwise with the left pull-out assembly 500. Similarly, the right pull-out assembly 600 will drive the right door 200 to rotate counterclockwise, thereby opening the door. It should be noted that the rope segments here are used for ease of description and do not mean that the pull-out assembly is segmented.

[0059] Furthermore, both the left pull assembly 500 and the right pull assembly 600 are made of steel wire rope. Steel wire rope possesses high tensile strength and toughness, enabling it to transmit loads over long distances, providing a high safety factor and ensuring safe and reliable operation. Due to its lightweight nature, steel wire rope is easy to carry and transport, capable of withstanding various loads and variable loads, and exhibits high tensile strength, fatigue strength, and impact toughness. Under high-speed operating conditions, it demonstrates good wear resistance, shock resistance, and operational stability. It also exhibits good corrosion resistance, allowing it to operate normally in harsh environments with various harmful media. Moreover, steel wire rope has good flexibility, making it suitable for traction, pulling, and binding. Therefore, the selection of steel wire rope as the pull assembly ensures stable and reliable operation.

[0060] Furthermore, the arc-shaped opening and closing door also includes a controller, which is electrically connected to the drive assembly 300. The controller controls the running time of the motor 310, ensuring operational stability. In an optional embodiment of this utility model, the controller is a PLC.

[0061] Furthermore, it also features an industrial remote controller and receiver, both of which are electrically connected to the drive assembly 300 to enable remote control functionality.

[0062] The working process of this utility model is as follows: The integrated hydraulic telescopic rod 330 drives the steel wire rope. By pulling the steel wire rope, the steel wire rope rotates on the pulley on the track 400, thereby driving the left door 100 and the right door 200 to open and close in an arc shape. The travel of the telescopic rod 330 is fixed, achieving precise opening and closing of the door. PLC delay control optimizes the running time of the motor 310, ensuring operational stability. The addition of an industrial remote controller and receiver enables remote control functionality, allowing this type of opening and closing door to be programmed for control during operation while reducing the failure rate to almost zero.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
