Description

Technical Field

[0001] This application relates to the field of tire processing equipment technology, and in particular to an adjustable bead support transport trolley for agricultural radial tires. Background Technology

[0002] Radial tires are a type of tire structure. Agricultural radial tires vary widely in size, ranging from 20 inches to 42 inches in diameter and from 300mm to 800mm in height. Their vulcanization process is relatively long, thus requiring transportation vehicles capable of handling tires of different sizes and specifications during placement and transport to improve the reliability of the manufacturing process.

[0003] Currently, in related technologies, various types of transport vehicles of different specifications are generally used, each corresponding to a different model of tire, in order to achieve the transportation and placement of tires.

[0004] However, due to the relatively small production volume of agricultural radial tires, using different specifications of transport vehicles can easily result in a large number and variety of vehicle models, occupying a lot of space and wasting resources. In addition, the tire bead is prone to collapse, and the transport vehicles in related technologies do not have bead support functions. If the tires are not vulcanized in time, the bead will collapse, causing potential quality problems.

[0005] Among the aforementioned related technologies, there are drawbacks such as poor applicability of the conveyor vehicle and lack of sub-port support. Utility Model Content

[0006] To address the issues of poor applicability and lack of bead support in transport vehicles, this application provides an agricultural radial tire adjustable bead support transport trolley.

[0007] The agricultural radial tire adjustable bead support transport trolley provided in this application adopts the following technical solution:

[0008] An adjustable bead support transport trolley for agricultural radial tires includes: a moving mechanism; a lifting mechanism mounted on the moving mechanism for vertical lifting; a supporting mechanism mounted on the lifting mechanism for supporting the agricultural radial tire, the supporting mechanism having an adjustable supporting diameter; and a support mechanism connected to the supporting mechanism for supporting the bead of the agricultural radial tire, the support mechanism having an adjustable supporting diameter.

[0009] By adopting the above technical solutions, convenient transportation and stable support for agricultural radial tires are achieved. The mobile mechanism allows the entire device to move flexibly and adapt to different work site requirements; the lifting mechanism enables vertical lifting, facilitating adjustment of the support position according to different height requirements; the adjustable support diameter of the support mechanism allows it to adapt to agricultural radial tires of different sizes, improving the device's versatility; the adjustable support diameter of the support mechanism further enhances the stable support for the bead of the agricultural radial tire, reducing the risk of bead collapse, thereby helping to improve the subsequent vulcanization quality.

[0010] Optionally, the lifting mechanism includes a lower fixed member, a lower sliding member, a hinge frame, an upper fixed member, an upper sliding member, a lifting seat, and a drive assembly. The lower fixed member is connected to the moving mechanism, and the lower sliding member is slidably connected to the moving mechanism. The upper fixed member is located above the lower fixed member, and the upper sliding member is located above the lower sliding member. The hinge frame is X-shaped, with its two upper ends hinged to the upper fixed member and the upper sliding member, and its two lower ends hinged to the lower fixed member and the lower sliding member, respectively. The lifting seat is connected to the upper fixed member and slidably connected to the upper sliding member. The drive assembly is connected to the lifting seat and is drively connected to the upper sliding member. The drive assembly is used to drive the upper sliding member to slide horizontally to adjust the height of the hinge frame.

[0011] By adopting the above technical solution, the lifting function of the adjustable bead support transport trolley for agricultural radial tires is realized. By setting up a lower fixed component, a lower sliding component, an upper fixed component, and an upper sliding component, combined with an X-shaped articulated frame, the lifting seat above the articulated frame can stably achieve vertical lifting and lowering, adapting to different height support requirements. The drive component drives the upper sliding component to slide horizontally, adjusting the height of the articulated frame, thereby achieving precise lifting and lowering control and improving the convenience and efficiency of operation.

[0012] Optionally, the drive assembly includes a horizontal lead screw, a horizontal lead nut, and a horizontal crank. The two ends of the horizontal lead screw are rotatably connected to the lifting seat. The horizontal lead nut is sleeved on the outer periphery of the upper sliding member and screwed to the horizontal lead screw. The horizontal crank is located at the end of the horizontal lead screw and is used to drive the horizontal lead screw to rotate.

[0013] By adopting the above technical solution, the cooperation of the horizontal lead screw, horizontal nut, and horizontal crank can achieve precise control of the upper sliding component. The screw connection between the horizontal lead screw and the horizontal nut allows the rotation of the horizontal lead screw to be converted into the linear motion of the horizontal nut, thereby driving the upper sliding component to slide horizontally. The design of the horizontal crank facilitates manual adjustment by the operator, improving ease of use and making the height adjustment of the lifting mechanism more stable and easier to operate.

[0014] Optionally, the supporting mechanism includes a lower supporting tray, an upper supporting tray, a rotating component, and several supporting assemblies. Each supporting assembly includes a connector, a supporting component, and a slide rail. The lower supporting tray is disposed on the lifting seat, and the upper supporting tray is disposed on the lower supporting tray. The rotating component is rotatably connected to the upper supporting tray. Several supporting assemblies are circumferentially distributed around the outer periphery of the rotating component. Several slide rails are arranged radially with the rotating component as the center. One end of the connector is hinged to the rotating component, and the other end of the connector is hinged to the supporting component. The supporting component is slidably connected to the slide rail.

[0015] By adopting the above technical solution, the support mechanism can effectively support agricultural radial tires, and the support diameter is adjustable. The combined use of the lower and upper support trays provides a stable support foundation. The rotating component rotates on the upper support tray, which drives the connecting component of the support assembly to move. This movement of the connecting component causes the support component to slide along the slide rail, thereby changing the distance between the center of the support component and the rotating component. This allows for the adjustment of the position of multiple support components to accommodate agricultural radial tires of different diameters. Several support components are circumferentially distributed around the outer periphery of the rotating component and their radial positions are flexibly adjusted via the slide rail. The two ends of the connecting component are hinged to the rotating component and the support component respectively, ensuring smooth sliding of the support component on the slide rail, thus achieving reliable adjustment of the support diameter. This design significantly improves the adaptability of the transport trolley to different types of agricultural radial tires, enhances operational convenience, and improves support stability.

[0016] Optionally, the support mechanism includes a mounting component and a plurality of support components. The mounting component is connected to the support mechanism. The first ends of the plurality of support components are circumferentially distributed around the outer periphery of the mounting component. The second ends of the support components extend away from the mounting component. The second ends of the support components are used to support the bead of the radial tire.

[0017] By adopting the above technical solution, stable support for the bead of the radial tire is achieved. The connection between the support assembly and the supporting mechanism ensures the overall stability of the support structure and provides a reliable support foundation for the bead of the radial tire. The first ends of several support components are circumferentially distributed around the outer periphery of the support assembly, which can evenly distribute the pressure on the bead of the radial tire and avoid deformation or damage caused by excessive local stress. The second ends of the support components extend away from the support assembly and are used to support the bead of the radial tire, effectively adapting to radial tires of different diameters and improving the applicability of the transport trolley.

[0018] Optionally, the mounting assembly includes a vertical screw, a vertical sleeve, a mounting plate, and several support columns. The lower end of the support column is connected to the upper support tray, and the upper end of the support column is connected to the mounting plate. The vertical screw passes through the support mechanism and the lifting mechanism. The vertical sleeve is sleeved on the outer periphery of the vertical screw and screwed to the vertical screw. The mounting plate is slidably sleeved on the outer periphery of the vertical sleeve, and the support components are distributed on the outer periphery of the vertical sleeve.

[0019] By adopting the above technical solution, several support columns firmly connect the upper support tray to the mounting plate, enhancing the stability of the overall structure. The screw connection between the vertical screw and the vertical sleeve allows the vertical sleeve to move vertically. The support components are distributed around the outer periphery of the vertical sleeve, thereby enabling attitude adjustment of the support components and achieving uniform and reliable support for the agricultural radial tire inlet, improving safety and reliability during transportation.

[0020] Optionally, the support mechanism includes a snap-fit ​​element, and the support assembly includes a first hinge element, a second hinge element, and a support body. The snap-fit ​​element is located below the mounting plate and snaps into the vertical sleeve, causing the snap-fit ​​element to be rotatably connected to the vertical sleeve and restricting the relative vertical movement between the snap-fit ​​element and the vertical sleeve. The first end of the first hinge element is hinged to the mounting plate, the first end of the second hinge element is hinged to the snap-fit ​​element, the second end of the first hinge element is hinged to the second hinge element, and the second end of the second hinge element is connected to the support body. The support body is used to support the bead of the radial tire.

[0021] By adopting the above technical solution, flexible adjustment and stable support of the support components in the support mechanism are achieved. The snap-fit ​​design between the snap-fit ​​member and the vertical sleeve restricts vertical movement while allowing relative rotation between them. This enables the vertical position of the snap-fit ​​member to change, and by altering the distance between the snap-fit ​​member and the mounting plate, the posture of the support component connecting the snap-fit ​​member and the mounting plate can be changed. This allows the support body to reliably support tire beads of different specifications. The combined use of the first and second hinge members enhances the flexibility and adaptability of the support body, allowing adjustment according to the bead shape of radial tires, ensuring effective support for radial tire beads, and improving safety and reliability during transportation.

[0022] Optionally, the support assembly includes an elastic element, the second end of the second hinge is hinged to the upper part of the support body, the first end of the elastic element is hinged to the second hinge, and the second end of the elastic element is hinged to the lower part of the support body, so that the tilt angle of the support body is adjustable.

[0023] By adopting the above technical solution, the elastic element in the support assembly enables the adjustability of the support body's tilt angle. The first end of the elastic element is hinged to a second hinge element, and the second end is hinged to the lower part of the support body. This structural design allows the support body to change its tilt angle under external force, while the elastic element provides a restoring force, ensuring that the support body adjusts its angle within an appropriate range. This better adapts to radial tire bead shapes and sizes, improving the stability and applicability of the support.

[0024] Optionally, the support body has a curvature.

[0025] By adopting the above technical solution, the support body has an arc shape that can better fit the shape of the radial tire bead, increase the contact area, thereby improving the support stability, reducing local pressure on the radial tire bead, and avoiding damage.

[0026] Optionally, the moving mechanism includes a support frame and a roller assembly, the support frame being used to support the lifting mechanism, and the roller assembly being located below the support frame.

[0027] By adopting the above technical solution, the moving mechanism consists of a support frame and a roller assembly. The support frame is used to stabilize the lifting mechanism and ensure the structural stability of the entire transport trolley. The roller assembly is located below the support frame, giving the transport trolley good mobility and facilitating the flexible transfer of agricultural radial tires between different locations, thereby improving work efficiency.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. By coordinating the moving mechanism and the lifting mechanism, flexible adjustment and stable support of agricultural radial tires are achieved during transportation, effectively solving the problem that traditional equipment cannot simultaneously meet the requirements of height adjustment and support of tires of different specifications;

[0030] 2. The support diameter of the support mechanism is adjustable, which can accommodate agricultural radial tires of various sizes, thus avoiding transportation instability caused by different tire specifications.

[0044] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be further described in detail below. In this embodiment, unless otherwise specified, "connection", "linking", and "fixing" are interpreted broadly, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection, and interaction between two components, etc., and can be understood according to the specific circumstances.

[0045] In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, in the description of this embodiment, terms such as "above," "below," "left," and "right," etc., are based on the orientation or positional relationships shown in the accompanying drawings and are used only for ease of description and simplification of operation. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise stated, directional terms such as "inner" and "outer" used in this application refer to the outline of the corresponding component itself.

[0046] like Figure 1 and Figure 2 As shown in the embodiment of this application, an adjustable bead support transport trolley for agricultural radial tires (hereinafter referred to as "transport trolley") is disclosed. The transport trolley includes a moving mechanism 1, a lifting mechanism 2, a supporting mechanism 3, and a supporting mechanism 4. The transport trolley has a simple structure and is easy to operate. It is used to transport tire blanks from the molding workshop to the vulcanization workshop, realizing convenient transportation and stable support for agricultural radial tires, which helps to promote efficient and high-quality production.

[0047] The moving mechanism 1 allows the entire device to move flexibly and adapt to different work site requirements. The lifting mechanism 2, mounted on the moving mechanism 1, is used for vertical lifting to meet the height requirements for placement, gripping, and operation, alleviating the problem of significant height differences between tire blanks of different specifications. The supporting mechanism 3, mounted on the lifting mechanism 2, supports the agricultural radial tire; its supporting diameter is adjustable. This adjustable diameter allows it to accommodate agricultural radial tires of different sizes, improving the device's versatility. The lifting mechanism 2 enables vertical lifting, facilitating adjustment of the supporting height of the supporting mechanism 3 according to different height requirements. The support mechanism 4, connected to the supporting mechanism 3, supports the bead of the agricultural radial tire; its supporting diameter is also adjustable. This adjustable diameter further enhances the stable support for the agricultural radial tire bead, reducing the risk of bead collapse and thus contributing to improved subsequent vulcanization quality.

[0048] like Figure 1 and Figure 3As shown, optionally, the moving mechanism 1 includes a support frame 11 and a roller assembly 12. The support frame 11 supports the lifting mechanism 2, ensuring the structural stability of the entire transport trolley. The roller assembly 12 is located below the support frame 11, giving the transport trolley good mobility and facilitating flexible transfer of agricultural radial tires between different positions, thus improving work efficiency. A pulling assembly 13 is provided on one side of the support frame 11. The pulling assembly 13 is used to hook onto the support component, so that the transport trolley can be driven by pulling the pulling assembly 13.

[0049] like Figure 1 , Figure 4 and Figure 5 As shown, optionally, the lifting mechanism 2 includes a lower fixed member 21, a lower sliding member 22, a hinge frame 23, an upper fixed member 24, an upper sliding member 25, a lifting seat 26, and a drive assembly 27. The lower fixed member 21 is connected to the moving mechanism 1, the lower sliding member 22 is slidably connected to the moving mechanism 1, the upper fixed member 24 is located above the lower fixed member 21, and the upper sliding member 25 is located above the lower sliding member 22. The hinge frame 23 is X-shaped, with the upper fixed member 24 and the upper sliding member 25 hinged to its two upper ends, and the lower fixed member 21 and the lower sliding member 22 hinged to its two lower ends, respectively. The lifting seat 26 is connected to the upper fixed member 24 and slidably connected to the upper sliding member 25. By setting the lower fixed member 21, the lower sliding member 22, the upper fixed member 24, and the upper sliding member 25, and combining them with the X-shaped hinge frame 23, the lifting seat 26 above the hinge frame 23 can stably achieve vertical lifting and lowering, adapting to different height support requirements. The drive assembly 27 is connected to the lifting base 26 and is also connected to the upper sliding member 25. The drive assembly 27 drives the upper sliding member 25 to slide horizontally, thereby changing the horizontal distance between the upper sliding member 25 and the upper fixed member 24, and thus adjusting the height of the articulated frame 23. By driving the upper sliding member 25 to slide horizontally, the drive assembly 27 adjusts the height of the articulated frame 23, thereby achieving precise lifting control and improving the convenience and efficiency of operation.

[0050] The hinge frame 23 may include two sets of X-shaped supports, each set of supports having a central hinge structure and hinged connections at both the upper and lower ends. The two sets of supports are arranged parallel to each other between the moving mechanism 1 and the lifting seat 26, so that the horizontal movement of one upper end of the hinge frame 23 can be converted into a change in the vertical height of the upper end of the hinge frame 23. The lifting seat 26 includes a lifting body and an upper auxiliary frame, with an upper sliding member 25 sliding between the lifting body and the upper auxiliary frame; the support frame 11 includes a support body and a lower auxiliary frame, with a lower sliding member 22 sliding between the support body and the lower auxiliary frame.

[0051] like Figure 1 , Figure 3 and Figure 4As shown, optionally, the drive assembly 27 includes a horizontal lead screw 271, a horizontal nut 272, and a horizontal crank 273. The cooperation of the horizontal lead screw 271, the horizontal nut 272, and the horizontal crank 273 enables precise control of the upper sliding member 25. The two ends of the horizontal lead screw 271 are rotatably connected to the lifting seat 26. The horizontal nut 272 is sleeved on the outer periphery of the upper sliding member 25 and can be slidably connected to the lifting seat 26. The horizontal nut 272 is screwed to the horizontal lead screw 271, so that the rotation of the horizontal lead screw 271 can be converted into the linear motion of the horizontal nut 272, thereby driving the upper sliding member 25 to slide horizontally. The horizontal crank 273 is located at the end of the horizontal lead screw 271 and is used to drive the horizontal lead screw 271 to rotate, facilitating manual adjustment by the operator, improving ease of use, and making the height adjustment of the lifting mechanism 2 more stable and easier to operate. The horizontal lead screw 271 is rotatably connected to the lifting seat 26 via a support base.

[0052] like Figure 1 , Figure 4 and Figure 6 As shown, optionally, the supporting mechanism 3 includes a lower supporting tray 31, an upper supporting tray 32, a rotating member 33, and several supporting components 34. Each supporting component 34 includes a connecting member 341, a supporting member 342, and a slide rail 343. The lower supporting tray 31 is mounted on the lifting seat 26, and the upper supporting tray 32 is mounted on the lower supporting tray 31. The rotating member 33 is rotatably connected to the upper supporting tray 32. Several supporting components 34 are circumferentially distributed around the rotating member 33, and several slide rails 343 are arranged radially with the rotating member 33 as the center. In the same supporting component 34, one end of the connecting member 341 is hinged to the rotating member 33, and the other end of the connecting member 341 is hinged to the supporting member 342. The supporting member 342 is slidably connected to the slide rail 343, allowing the supporting member 342 to adjust its position according to different tire diameters.

[0053] The combined use of the lower support tray 31 and the upper support tray 32 provides a stable support foundation. The rotating component 33 rotates on the upper support tray 32, driving the connecting component 341 of the support assembly 34 to move. This movement of the connecting component 341 causes the support component 342 to slide along the slide rail 343, thereby changing the distance between the center of the support component 342 and the center of the rotating component 33. This allows for adjustment of the position of multiple support components 342 to accommodate agricultural radial tires of different diameters. Several support components 34 are circumferentially distributed around the outer periphery of the rotating component 33, and their radial positions are flexibly adjusted via the slide rail 343. The two ends of the connecting component 341 are hinged to the rotating component 33 and the support component 342 respectively, ensuring smooth sliding of the support component 342 on the slide rail 343, thus achieving reliable adjustment of the support diameter. This design significantly improves the adaptability of the transport trolley to different types of agricultural radial tires, enhancing operational convenience and support stability. The support member 342 is used to support the tire sidewall. A pad can be placed under the support member 342 to adjust the height of the support member 342, thus alleviating interference caused by the protrusion of the tire carcass at the bead and the slide rail 343. The support mechanism 3 can be manually driven to accommodate tires of different sizes. Simultaneously, the support member 342 has a curved shape so that when the tire carcass is stored, the pressure is mainly borne by the rim and sidewall, reducing the impact on the bead slope.

[0054] like Figure 1 , Figure 6 and Figure 7 As shown, optionally, the support mechanism 4 includes a mounting component and several support components. The mounting component connects to the support mechanism 3, ensuring the overall stability of the support mechanism 4 and providing a reliable support foundation for the radial tire bead. The first ends of the several support components are circumferentially distributed around the outer periphery of the mounting component, which can evenly distribute the pressure on the radial tire bead and avoid excessive local stress leading to deformation or damage. The second ends of the support components extend away from the mounting component, and the second ends of the support components are used to support the radial tire bead, effectively adapting to radial tires of different diameters and improving the applicability of the transport trolley.

[0055] like Figure 1 , Figure 6 and Figure 7As shown, optionally, the mounting assembly includes a vertical lead screw 411, a vertical sleeve 412, a mounting plate 413, and several support columns 414. The lower end of the support column 414 is connected to the upper support plate 32, and the upper end of the support column 414 is connected to the mounting plate 413. The several support columns 414 firmly connect the upper support plate 32 and the mounting plate 413, enhancing the stability of the overall structure. The vertical lead screw 411 passes through the support mechanism 3 and the lifting mechanism 2, and is connected to the bearing frame 11 to achieve a supporting function. The vertical sleeve 412 is sleeved on the outer periphery of the vertical lead screw 411, and the internal thread of the vertical sleeve 412 is screwed to the vertical lead screw 411, allowing the vertical sleeve 412 to move in the vertical direction. The mounting plate 413 is slidably sleeved on the outer periphery of the vertical sleeve 412, and the support components are distributed on the outer periphery of the vertical sleeve 412, thereby enabling the attitude adjustment of the support components, and thus achieving uniform and reliable support for the agricultural meridional tire opening, improving the safety and reliability during transportation.

[0056] like Figure 1 , Figure 6 and Figure 7 As shown, optionally, the support mechanism 4 includes a snap-fit ​​member 43 located below the mounting plate 413. The snap-fit ​​member 43 snaps into the vertical sleeve 412, allowing the snap-fit ​​member 43 to be rotatably connected to the vertical sleeve 412 and restricting the relative vertical movement between the snap-fit ​​member 43 and the vertical sleeve 412. The support assembly includes a first hinge member 421, a second hinge member 422, and a support body 423. The snap-fit ​​design between the snap-fit ​​member 43 and the vertical sleeve 412, while restricting vertical movement, allows the snap-fit ​​member 43 and the vertical sleeve 412 to rotate relative to each other, enabling multiple support components to open or retract relative to each other. This allows the vertical position of the snap-fit ​​member 43 to change. By changing the distance between the snap-fit ​​member 43 and the mounting plate 413, the posture of the support assembly connected between the snap-fit ​​member 43 and the mounting plate 413 can be changed, thereby enabling the support body 423 to reliably support tire bead sizes.

[0057] The first end of the first hinge member 421 is hinged to the mounting plate 413, the first end of the second hinge member 422 is hinged to the snap-fit ​​member 43, the second end of the first hinge member 421 is hinged to the second hinge member 422, and the second end of the second hinge member 422 is connected to the support body 423, which is used to support the bead of the radial tire. The cooperative use of the first hinge member 421 and the second hinge member 422 enhances the flexibility and adaptability of the support body 423, allowing it to be adjusted according to the bead shape of the radial tire, ensuring effective support for the radial tire bead, and improving safety and reliability during transportation.

[0058] like Figure 1 , Figure 6 and Figure 7As shown, optionally, the support body 423 has an arc, which can better fit the bead shape of the agricultural radial tire, increase the contact area, thereby improving the support stability, reducing local pressure on the bead of the radial tire, and avoiding damage.

[0059] like Figure 1 , Figure 6 and Figure 7 As shown, optionally, the support assembly includes an elastic element 424. The second end of the second hinge 422 is hinged to the upper part of the support body 423, the first end of the elastic element 424 is hinged to the second hinge 422, and the second end of the elastic element 424 is hinged to the lower part of the support body 423, making the tilt angle of the support body 423 adjustable. The elastic element 424 allows the support body 423 to change its tilt angle under the action of external force, while providing a restoring force to ensure that the support body 423 adjusts its angle within an appropriate range, thereby better adapting to radial tire beads of different shapes and sizes, and improving the stability and applicability of the support. A vertical handle 415 is provided at the upper end of the vertical sleeve 412. By manually cranking the vertical handle 415, the spatial position of the support body 423 is adjusted. When the support body 423 contacts the tire bead, the elastic element 424 can adjust the tilt angle of the support body 423 until the support body 423 can reliably fit with the tire bead, thereby providing effective bead support. The elastic element 424 can be a spring.

[0060] It is understandable that the transport trolley also includes necessary structures for connection, support, drive, positioning, limiting and control functions, so that the transport trolley can operate normally; the shape, size, material and quantity of each part of the transport trolley can be determined as needed, as long as it can achieve the corresponding functions.

[0061] The implementation principle of the adjustable bead support transport trolley for agricultural radial tires in this embodiment is as follows: the tire blank is placed on the support mechanism 3, and the support diameter of the support mechanism 3 is adjusted to adapt it to the agricultural radial tire; the support diameter of the support mechanism 4 is adjusted to achieve stable support for the bead of the agricultural radial tire, reducing the risk of tire bead collapse, thereby helping to improve the subsequent vulcanization quality; the lifting mechanism 2 is adjusted to adjust the support position according to different height requirements; and the moving mechanism 1 enables the entire device to move flexibly to adapt to different work site requirements.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
