Description

Technical Field

[0001] This application relates to the field of tire assembly technology, and in particular to a manual tire loading machine. Background Technology

[0002] With the rapid development of the tire manufacturing industry, the demand for tire installation continues to grow. Traditional manual tire installation methods suffer from low efficiency, insufficient precision, and high labor costs, making it difficult to meet the needs of modern industrial production. The installation of solid inner tubes, in particular, is more difficult and error-prone by hand due to their special structure and materials, necessitating the use of tire-installing machines.

[0003] Traditional tire loading machines are mostly automated, but they are large, expensive, require a lot of space, are not easy to move, and cannot meet the needs of rapid on-site installation. Utility Model Content

[0004] Therefore, it is necessary to provide a manual tire loading machine to reduce the size and weight of the equipment, make it easy to move, meet the needs of rapid on-site installation, and reduce production costs.

[0005] A manual tire loading machine, comprising:

[0006] frame;

[0007] A turntable mechanism is rotatably connected to the frame, and the turntable mechanism is used to place the wheel hubs and solid tires to be assembled;

[0008] A connecting frame is movably connected to the frame and can move relative to the frame in a direction perpendicular to the axis of the turntable mechanism;

[0009] A pressure shaft mechanism is installed on the connecting frame, and the pressure shaft mechanism is used to limit the position of the hub placed on the turntable mechanism;

[0010] A manual displacement stage is mounted on the connecting frame and has an output end;

[0011] The pressure roller mechanism and the rolling mechanism are both installed at the output end. The output end can move relative to the connecting frame to drive the pressure roller mechanism and the rolling mechanism to move axially along the turntable mechanism, so that the pressure roller mechanism abuts against the solid tire, and the rolling mechanism is used to press the solid tire into the wheel hub.

[0012] In one embodiment, the turntable mechanism includes a turntable body and a drive rod. The turntable body has a receiving cavity, and the bottom of the receiving cavity has a connecting hole. The frame has a rotating shaft corresponding to the connecting hole. The outer wall of the turntable body has a mounting hole, and one end of the drive rod is inserted into the mounting hole.

[0013] In one embodiment, the receiving cavity is provided with a positioning boss coaxial with the connecting hole, and the positioning boss is provided with a first limiting hole along the axial direction. The first limiting hole is used to cooperate with one end of the hub shaft for limiting.

[0014] The pressure shaft mechanism includes a pressure head, which is slidably connected to the connecting frame and can slide along the axial direction of the turntable body. The end of the pressure head facing the first limiting hole is provided with a second limiting hole, which is used to cooperate with one end of the hub shaft for limiting.

[0015] In one embodiment, the pressure shaft mechanism further includes a limiting plate, which is disposed at the end of the pressure head away from the turntable mechanism. The projected area of ​​the limiting plate on a plane perpendicular to the axis of the turntable mechanism is greater than the projected area of ​​the pressure head on a plane perpendicular to the axis of the turntable mechanism.

[0016] In one embodiment, the rolling mechanism includes a connecting arm and a roller assembly. One end of the connecting arm is detachably connected to the output end of the manual displacement stage, and the other end of the connecting arm is inclined toward one side of the turntable mechanism. The roller assembly is connected to the end of the connecting arm away from the output end.

[0017] In one embodiment, the manual displacement stage includes a first frame, a drive shaft, and a second frame; the first frame is mounted on the connecting frame, the drive shaft extends axially along the turntable body, the two ends of the drive shaft are threadedly connected to the first frame and the second frame respectively, the second frame is slidably connected to the first frame, and the end of the connecting arm away from the turntable mechanism is detachably connected to the second frame.

[0018] In one embodiment, the second frame has an adjustment hole, and one end of the connecting arm has an adjustment screw corresponding to the adjustment hole. The threaded end of the adjustment screw passes through the adjustment hole and is threadedly connected to the connecting arm. The adjustment screw can move within the adjustment hole along the length direction of the adjustment hole.

[0019] In one embodiment, the rolling mechanism further includes an adjustment component connected to the second frame, the adjustment component being movable along the axial direction of the turntable mechanism until the output end of the adjustment component abuts against the side wall of the connecting arm.

[0020] In one embodiment, the pressure roller mechanism includes a connector and a pressure roller assembly. The connector is connected to the second frame and is movable along the axial direction of the turntable body. The pressure roller assembly is connected to the end of the connector away from the second frame.

[0021] In one embodiment, mounting bosses are evenly distributed around the outer wall of the turntable body, and mounting holes are provided on the mounting bosses.

[0022] The aforementioned manual tire loading machine, when assembling a wheel hub and solid tire, first places the wheel hub and solid tire to be assembled on a turntable mechanism. Then, a movable connecting frame moves relative to the machine frame in a direction perpendicular to the axis of the turntable mechanism, so that the pressure shaft mechanism limits the wheel hub axis. Subsequently, a manually driven displacement table drives the pressure roller mechanism and the rolling mechanism to move synchronously along the axial direction of the turntable mechanism and closer to the wheel hub until the pressure roller mechanism presses the outer wall of the solid tire. Then, the turntable mechanism is manually rotated, and the rolling mechanism presses the solid tire into the wheel hub. Thus, the aforementioned manual tire loading machine can achieve manual tire loading operation through a simple structural combination, which helps to reduce the size and weight of the equipment. At the same time, the entire manual tire loading machine can be moved by moving the machine frame, which can meet the needs of rapid on-site installation and reduce production costs.

Detailed Implementation

[0036] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and 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.

[0038] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0041] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0042] like Figure 1 and Figure 9 As shown, an embodiment of this application provides a manual tire loading machine, including a frame 1, a turntable mechanism 2, a connecting frame 3, a manual displacement table 4, a pressure shaft mechanism 5, a pressure roller mechanism 6, and a rolling mechanism 7. In the manual tire loading machine, the frame 1 serves as a mounting carrier for mounting the turntable mechanism 2 and the connecting frame 3.

[0043] Turntable mechanism 2 is rotatably connected to frame 1, such as Figure 9 As shown, the turntable mechanism 2 is used to place the wheel hub a and solid tire b to be assembled. By manually rotating the turntable mechanism 2, the wheel hub a and solid tire b are driven to rotate synchronously.

[0044] The connecting frame 3 serves as a carrier for mounting the manual displacement stage 4 and the pressure shaft mechanism 5. The connecting frame 3 is movably connected to the frame 1 and can move relative to the frame 1 in a direction perpendicular to the axis of the turntable mechanism 2. In this application, as... Figure 1 and Figure 9 As shown, the connecting frame 3 is located at the top of the frame 1, and the turntable mechanism 2 is located at the bottom of the frame 1. When placing the wheel hub a and solid tire b on the turntable mechanism 2, to avoid the manual displacement table 4 obstructing the placement of the wheel hub a and solid tire b, the connecting frame 3 is movably connected to the frame 1. When it is necessary to place the wheel hub a and solid tire b on the turntable mechanism 2, the connecting frame 3 can be moved away from the turntable mechanism 2 to avoid interference with the placement of the wheel hub a and solid tire b. After the wheel hub a and solid tire b are placed stably, the movable connecting frame 3 is positioned directly above the turntable mechanism 2, thereby allowing the next tire loading operation to proceed.

[0045] In one embodiment, to simplify the connection structure between the connecting frame 3 and the frame 1, the connecting frame 3 is slidably connected to the frame 1 and can move relative to the frame 1 in a direction perpendicular to the axis of the turntable mechanism 2. Specifically, in this application, the connecting frame 3 can move along the length direction of the frame 1, and the length direction of the frame 1 is perpendicular to the axis of the turntable mechanism 2. Further, to limit the sliding of the connecting frame 3 relative to the frame 1, a groove 31 is provided on the circumferential sidewall of the connecting frame 3, and a corresponding limiting structure corresponding to the groove 31 can be provided on the frame 1.

[0046] The manual displacement table 4 is installed on the connecting frame 3. In this application, the tire loading machine is operated entirely by manual control. The manual displacement table 4 has an output end, which can move relative to the connecting frame 3 and can move along the axial direction of the turntable mechanism 2. It is used to drive the pressure roller mechanism 6 and the rolling mechanism 7 to approach the turntable mechanism 2 to complete the installation of the wheel hub a and the tire.

[0047] The pressure shaft mechanism 5 is mounted on the connecting frame 3 and is used to limit the position of the wheel hub a placed on the turntable mechanism 2. Specifically, after the wheel hub a is placed on the turntable mechanism 2, the pressure shaft mechanism 5 is used to limit the position of the wheel hub a in the horizontal direction to prevent the position of the wheel hub a from shifting during tire loading.

[0048] The pressure roller mechanism 6 is installed at the output end of the manual displacement table 4. Driven by the manual displacement table 4, the pressure roller mechanism 6 can move axially along the turntable mechanism 2 to press against the solid tire b. Figure 9 As shown, before the solid tire b is pressed into the rim a, one end of the solid tire b is inserted into the rim a along the axial direction, and the other end is located outside the rim a. When pressing the end located outside the rim a into the rim a, the outer wall of the solid tire b needs to be pressed and pressed by the pressing wheel mechanism 6.

[0049] The rolling mechanism 7 is installed at the output end of the manual displacement table 4, such as... Figure 10 , Figure 11 As shown, the pressure wheel mechanism 6 can move along the axial direction of the turntable mechanism 2 under the drive of the manual displacement table 4, and is used to press the solid tire b into the wheel hub a.

[0050] It should be noted that the assembly process of wheel hub a and solid tire b is as follows: Figures 9 to 11 As shown, the hub shaft (not shown in the figure) is located at the center of hub a and protrudes from both ends of hub a. In this application, both the turntable mechanism 2 and the manual displacement table 4 are manually driven. This application does not involve electrical or hydraulic drive components. Manual tire loading can be achieved through simple structural cooperation, which helps to reduce the size and weight of the equipment. Therefore, in use, the tire loading machine only needs to be moved to the designated position to meet the needs of rapid on-site installation and reduce production costs.

[0051] In one embodiment, such as Figure 4 As shown, the turntable mechanism 2 includes a turntable body 21 and a drive rod 22. The turntable body 21 has a receiving cavity 211 to prevent interference when the hub a is placed. A connecting hole 212 is provided at the bottom of the receiving cavity 211, and a rotating shaft 111 corresponding to the connecting hole 212 is provided on the frame 1. A mounting hole 2131 is provided circumferentially on the outer wall of the turntable body 21, and one end of the drive rod 22 is inserted into the mounting hole 2131. When the turntable body 21 is rotatably connected to the frame 1, the rotating shaft 111 on the frame 1 is inserted into the connecting hole 212 of the turntable body 21, thereby achieving a rotatable connection between the turntable body 21 and the frame 1.

[0052] In one embodiment, to facilitate manual rotation of the turntable body 21, the turntable mechanism 2 is provided with a drive rod 22. In use, one end of the drive rod 22 is inserted into the mounting hole 2131, and the other end is manually pushed to rotate the turntable body 21 around the shaft 111. In some embodiments, the mounting hole 2131 is a blind hole, and the drive rod 22 is slidably connected to the mounting hole 2131, facilitating quick installation of the drive rod 22. In some other embodiments, to avoid the risk of the drive rod 22 slipping out of the mounting hole 2131 due to position changes after rotation with the turntable body 21 when the drive rod 22 is pushed, an internal thread is provided on the inner wall of the mounting hole 2131, and an external thread is provided on the outer wall of the drive rod 22, with the drive rod 22 threadedly connected to the mounting hole 2131.

[0053] In one embodiment, since the blind hole needs to have a certain depth, in order to reduce the overall thickness of the turntable body 21 and save materials, such as Figure 4 As shown, mounting bosses 213 are evenly distributed around the outer wall of the turntable body 21, and mounting holes 2131 are provided on the mounting bosses 213.

[0054] In one embodiment, to limit the position of the wheel hub a after placement, specifically, the wheel hub a's axle is limited, thereby achieving overall limitation of the wheel hub a. In this application, as... Figure 8 As shown, the receiving cavity 211 is provided with a positioning boss 214 coaxial with the connecting hole 212. The positioning boss 214 has a first limiting hole 2141 along the axial direction, which is used to limit the movement of one end of the wheel hub shaft. The pressing mechanism 5 includes a pressing head 51, which is slidably connected to the connecting frame 3 and can slide along the axial direction of the turntable body 21. The end of the pressing head 51 facing the first limiting hole 2141 has a second limiting hole 511, which is used to limit the movement of one end of the wheel hub shaft. The wheel hub shaft is limited by the cooperation of the first limiting hole 2141 on the turntable body 21 and the second limiting hole 511 on the pressing head 51. It should be noted that since hub a has a certain weight, and one end of the hub axle is inserted into the first limiting hole 2141 and the other end is inserted into the second limiting hole 511, hub a will not move in the direction of gravity. Therefore, in this application, the pressure head 51 does not need to press the hub axle. This further simplifies the limiting structure of hub a and reduces costs.

[0055] In one embodiment, the pressure head 51 is slidably connected to the connecting frame 3. This is to facilitate the sliding of the pressure head 51 relative to the connecting frame 3 and to prevent jamming. Figure 8 As shown, the pressure head 51 has a cylindrical structure, and the connecting frame 3 is equipped with a bearing corresponding to the pressure head 51. To prevent the pressure head 51 from sliding directly out of the bearing hole, the pressure shaft mechanism also includes a limiting plate 52. The limiting plate 52 is located at the end of the pressure head 51 away from the turntable mechanism 2. The projected area of ​​the limiting plate 52 on the plane perpendicular to the axis of the turntable mechanism is larger than the projected area of ​​the pressure head 51 on the plane perpendicular to the axis of the turntable mechanism. When using the pressure head 51 to position the hub a, the pressure head 51 is slid upward, and the connecting frame 3 is moved synchronously to directly above the hub a so that the hub shaft is aligned with the second limiting hole 511. Then, the pressure head 51 is released, and the hub shaft can be inserted into the second limiting hole 511, thereby limiting the hub shaft through the first limiting hole 2141 and the second limiting hole 511. In addition, to prevent the bottom end of the pressure head 51 from coming out of the bearing hole when the pressure head 51 slides upward, an annular boss 512 is provided on the outer wall of the end of the pressure head 51 near the turntable body 21.

[0056] like Figure 3 and Figure 5As shown, in order to press a solid tire b into a wheel hub a, in one embodiment, the rolling mechanism 7 includes a connecting arm 71 and a roller assembly 72. One end of the connecting arm 71 is detachably connected to the output end of the manual displacement table 4, and the other end of the connecting arm 71 is inclined towards the side closer to the turntable mechanism 2. The roller assembly 72 is connected to the end of the connecting arm 71 away from the output end of the manual displacement table 4. The manual displacement table 4 can drive the pressing roller mechanism 6 to move closer to the turntable mechanism 2, so that the outer wall of the roller assembly 72 abuts against the axial outer wall of the tire, pressing the solid tire b into the wheel hub a. Since one end of the connecting arm 71 is detachably connected to the output end of the manual displacement table 4, when it is necessary to assemble wheel hubs a and solid tires b of different specifications, the installation position of the connecting arm 71 and the manual displacement table 4 can be adjusted. Therefore, the manual tire loading machine in this application has versatility.

[0057] like Figure 2 , Figure 3 As shown, to simplify the structure of the manual displacement stage 4 and reduce production costs, in one embodiment, the manual displacement stage 4 includes a first frame 41, a drive shaft 42, and a second frame 43. The first frame 41 is mounted on the connecting frame 3. The drive shaft 42 extends axially along the turntable body 21, and both ends of the drive shaft 42 are threadedly connected to the first frame 41 and the second frame 43 respectively. The second frame 43 is slidably connected to the first frame 41, and the end of the connecting arm 71 away from the turntable mechanism 2 is detachably connected to the second frame 43. In this application, rotating the drive shaft 42 moves the second frame 43 axially along the drive shaft 42. To reduce processing costs, the drive shaft 42 can be directly selected as a lead screw. Furthermore, to facilitate rotation of the drive shaft 42, a handwheel is provided at the end of the drive shaft 42 away from the second frame 43; rotating the handwheel rotates the drive shaft 42.

[0058] Furthermore, such as Figure 5 , Figure 6 As shown, to facilitate adjustment of the installation position between the connecting arm 71 and the second frame 43, in one embodiment, the second frame 43 has an adjustment hole, and one end of the connecting arm 71 has an adjustment screw 721 corresponding to the adjustment hole. The threaded end of the adjustment screw 721 passes through the adjustment hole and is threadedly connected to the connecting arm 71. The adjustment screw 721 can move within the adjustment hole along the length direction of the adjustment hole. In this application, the extension direction of the adjustment hole is the same as the length direction of the frame 1. That is, when adjusting the installation position between the connecting arm 71 and the second frame 43, loosening the adjustment screw 721 allows the tilt angle of the connecting arm 71 to be adjusted. At the same time, the adjustment screw 721 can move along the length direction of the adjustment hole, thereby adjusting the position of the roller assembly 72 to meet the assembly of different specifications of hub a and solid tire b.

[0059] It should be noted that the roller assembly 72 includes a connecting shaft and rollers, which are standard parts and can be purchased directly. One end of the connecting shaft is fixedly connected to the connecting arm 71, and the other end of the connecting shaft is rotatably connected to the rollers. During the process of the rollers pressing the outer wall of the solid tire b and pressing it into the wheel hub a, the rollers can rotate, which reduces the friction between the rollers and the solid tire b, and reduces the difficulty of manually installing the tire.

[0060] Furthermore, such as Figure 3 , Figure 7 As shown, since the connecting arm 71 is connected to the second frame 43 by an adjusting screw 721, when the rolling mechanism 7 presses the solid tire b into the hub a, the connecting arm 71 is subjected to a force opposite to gravity. To prevent the connecting arm 71 from rotating upwards, which would result in insufficient pressure when the solid tire b is pressed into the hub a and fail to meet assembly requirements, in one embodiment, the rolling mechanism 7 further includes an adjusting component 73. The adjusting component 73 is connected to the second frame 43 and can move axially along the turntable mechanism 2 until the output end of the adjusting component 73 abuts against the side wall of the connecting arm 71, preventing the connecting arm 71 from rotating upwards. This ensures the stability of the hub a and the solid tire b during assembly. In some embodiments, to simplify the structure of the adjusting component 73, the adjusting component 73 can be a screw. The second frame 43 can have a threaded hole corresponding to the screw. After the connecting arm 71 is installed, the installation height of the screw can be adjusted until the end of the screw abuts against the side wall of the connecting arm 71 to achieve the limit.

[0061] It should be noted that in this application, the second frame 43 is slidably connected to the first frame 41, such as... Figure 3 As shown, the first frame 41 has a limiting groove 411 arranged axially along the drive shaft 42, and the second frame 43 has a limiting block 431 corresponding to the limiting groove 411, thereby limiting the sliding position of the second frame 43 relative to the first frame 41. In some other embodiments, a linear guide rail can also be fixedly arranged on the first frame 41, and the second frame 43 can be connected to a slider on the linear guide rail to improve the limiting accuracy of the second frame 43 when it moves.

[0062] In one embodiment, to simplify the structure of the pressure roller mechanism 6 and reduce production costs, such as... Figure 3As shown, the pressure roller mechanism 6 includes a connector 61 and a pressure roller assembly 62. The connector 61 is connected to the second frame 43 and can move axially along the turntable body 21. The pressure roller assembly 62 is connected to the end of the connector 61 away from the second frame 43. To simplify the structure of the connector 61 and facilitate adjustment of the position of the pressure roller assembly 62 axially along the turntable body 21, the connector 61 can be made of a screw. The screw extends axially along the turntable body 21, with its threaded section penetrating the second frame 43 and its end connected to the pressure roller assembly 62. The position of the pressure roller assembly 62 axially along the turntable body 21 can be adjusted to meet the tire mounting requirements of different specifications of wheel hubs a and solid tires b. The pressure roller assembly 62 is a standard part and can be directly purchased; therefore, its structure will not be described in detail here.

[0063] In one embodiment, to ensure the installation strength of the frame 1, the frame 1 can be constructed from aluminum alloy or steel. Simultaneously, to facilitate the movement of the entire manual tire loading machine, casters can be installed at the bottom of the frame 1 for easy relocation. Furthermore, to facilitate the installation of the pivot 111 on the frame 1, a connecting plate 11 is provided on the frame 1, with the pivot 111 located on the connecting plate 11, facilitating processing and assembly.

[0064] It should be noted that, in this application, the assembly process of the manual tire mounting machine for the wheel hub a and the solid tire b is as follows: Figures 9 to 11 As shown. First, as Figure 9 As shown, the wheel hub a and the tire are placed on the turntable body 21, with one end of the wheel hub axle inserted into the first limiting hole 2141. Then, the connecting bracket 3 is moved above the turntable mechanism 2, while the other end of the wheel hub axle is inserted into the second limiting hole 511. Next, the manual displacement table 4 is operated to move the pressure roller mechanism 6 and the rolling mechanism 7 downwards synchronously, with both the pressure roller mechanism 6 and the rolling mechanism 7 abutting against the outer wall of the solid tire b. Then, the turntable mechanism 2 is manually rotated, as shown... Figure 10 As shown, the solid tire b is pressed into the wheel hub a under the pressure of the rolling mechanism 7. Thus, the aforementioned manual tire loading machine, through a simple structural design, enables manual tire loading, which helps reduce the size and weight of the equipment. Simultaneously, the movable frame allows for the overall movement of the manual tire loading machine, meeting the needs of rapid on-site installation and reducing production costs. After the wheel hub a and solid tire b are pressed into the wheel hub a, the manual displacement table 4 drives the pressure roller mechanism 6 and the rolling mechanism 7 to move upwards synchronously, causing one end of the wheel hub shaft to disengage from the second limiting hole 511. The moving connecting frame 3 moves away from the turntable mechanism 2, and finally, the assembled tire can be removed.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
