Description

Technical Field

[0001] This invention relates to the field of electrical distribution box installation technology, and more specifically, to an electrical distribution box installation structure and an electrical distribution box. Background Technology

[0002] Currently, distribution boxes are typically installed by directly fixing them to walls or columns using expansion bolts, or by using fixed brackets for transitional connections. This installation method has the following drawbacks: First, the distribution box and the mounting base are mostly fixed connections, making it impossible to adjust the box angle after installation. This makes wiring difficult in confined spaces, and maintenance often requires complete disassembly of the box, which can easily lead to loosening of the mounting holes. Second, existing brackets are mostly fixed structures, unable to compensate for angles based on the orientation or tilt of the mounting base, and difficult to avoid obstacles or adjust the box orientation in column-mounted installations. Third, distribution boxes and power cabinets are usually installed independently, requiring separate wiring connections, which takes up a lot of space and makes the installation process cumbersome. Fourth, existing positioning structures are mostly fixed structures corresponding to specific box sizes, making it difficult to adapt to different sizes of distribution boxes, resulting in poor versatility and requiring repeated adjustments or even replacement of brackets during installation. Summary of the Invention

[0003] Therefore, in order to solve the problems of non-adjustable angle and poor specification compatibility of existing distribution boxes after installation, this invention provides a distribution box installation structure and distribution box, the specific technical solution of which is as follows: A distribution box mounting structure includes a mounting base and a positioning device; an adjustable bracket is mounted on the mounting base via a drive module, and a power cabinet electrically connected to the distribution box is embedded in the adjustable bracket; the positioning device is mounted on the adjustable bracket, and the positioning device includes at least two positioning components, which are slidable relative to the adjustable bracket; one or more positioning modules are provided on each positioning component, and the positioning modules located on different positioning components enclose a positioning space for fixing the distribution box.

[0004] The aforementioned distribution box installation structure, by incorporating a drive module, allows the adjusting bracket to swing relative to the mounting base, thereby causing the power cabinet embedded within the adjusting bracket and the distribution box fixed to the adjusting bracket to rotate together, facilitating installation, wiring, maintenance, and angle adjustment. Simultaneously, the positioning device employs at least two positioning components that can slide relative to the adjusting bracket, with positioning modules mounted on these components. The positioning modules on different positioning components enclose a positioning space for fixing the distribution box, thus adapting to distribution boxes of different specifications and achieving rapid positioning and reliable fixing, improving installation flexibility and applicability.

[0005] Furthermore, the drive module includes a bearing seat, a connecting plate, a drive gear, and a driven gear meshing with the drive gear. The bearing seat is mounted on the mounting base, and a first rotating shaft and a second rotating shaft are rotatably inserted into the bearing seat. The drive gear is sleeved on the first rotating shaft, and the driven gear is sleeved on the second rotating shaft. The connecting plate is mounted on the side wall of the adjusting bracket, and the second rotating shaft is fixed on the connecting plate.

[0006] Furthermore, the drive module also includes a locking component, which includes a pawl and a ratchet. The ratchet is disposed on the circumferential edge of the driven gear, and the pawl is rotatably mounted on the shaft seat. One end of the pawl engages with the ratchet, and the other end of the pawl is connected to an elastic element. The elastic element causes the pawl to tend to abut against the ratchet. When the drive gear drives the driven gear to rotate in the forward direction, the ratchet pushes the pawl to overcome the elastic force of the elastic element and lift it up. When the drive gear stops driving, the pawl is engaged in the tooth groove of the ratchet under the action of the elastic element, preventing the driven gear from rotating in the reverse direction, thereby locking the adjustment bracket at the current angle.

[0007] Furthermore, the adjusting bracket is equipped with a fixed frame plate, and the upper and lower ends of the fixed frame plate are provided with first disassembly seats. A second disassembly seat is provided between the two first disassembly seats. The first disassembly seats are provided with a horizontal connecting module, and the second disassembly seat is provided with a vertical connecting module. The horizontal connecting module and the vertical connecting module are detachably connected to the outer wall of the power cabinet.

[0008] Furthermore, the positioning device also includes a receiving plate and two side plates. The receiving plate is connected between the two side plates and is used to support the distribution box. The side plates are mounted on the adjusting bracket. Each side plate is provided with a lifting guide rail. The positioning component is slidably assembled on the lifting guide rail.

[0009] Furthermore, the positioning component includes a sliding seat and one or more auxiliary modules disposed on the sliding seat. The sliding seat is provided with a first transverse guide rail. The positioning module is slidably mounted on the first transverse guide rail. The number of the positioning module and the number of the auxiliary modules are both two and correspond one-to-one. A pad is provided on the auxiliary module. The positioning module includes a first driving member, a swing arm and a pressure plate. The output end of the first driving member is drivenly connected to one end of the swing arm. The other end of the swing arm is fixedly connected to the pressure plate. The pad and the pressure plate cooperate to clamp at the corner between adjacent side walls of the distribution box.

[0010] Furthermore, the positioning device also includes a centering frame plate, a turntable, and a rotating module. The centering frame plate is mounted on the adjusting bracket, the turntable is located at the center of the centering frame plate, and a third rotating shaft is rotatably mounted on the turntable. The rotating module includes a rotating arm and two pull rods. The rotating arm is inserted into the third rotating shaft, one end of the rotating arm is connected to one of the pull rods, and the other end of the rotating arm is connected to the other pull rod. There are two positioning components, and the pull rods are connected to the positioning components and correspond one-to-one.

[0011] Furthermore, second transverse guide rails are provided on both sides of the centering frame plate; the positioning component includes a second driving member, a centering plate, and a slider slidably mounted on the second transverse guide rail. The second driving member is mounted on the centering frame plate, and the centering plate is fixedly mounted on the slider. The output end of the second driving member is in transmission cooperation with the centering plate. Multiple positioning modules are provided on the centering plate. Each positioning module is configured as a centering rod protruding from the centering plate. The multiple centering rods are spaced apart and are used to abut against the side wall of the distribution box.

[0012] A distribution box includes an outer box fixed within the positioning space, the outer box having a first chamber, an inner equipment box electrically connected to a power cabinet being installed in the first chamber, an openable and closable door being provided on one side wall of the outer box, and reinforcing mechanisms being provided on the remaining side walls of the outer box, the reinforcing mechanisms being used to enhance the structural rigidity of the outer box when the outer box is clamped or supported by the positioning module.

[0013] The aforementioned distribution box, by setting a first chamber inside the outer box and installing the inner equipment box inside it, forms an inner and outer layered structure inside the distribution box, which facilitates the independent installation and maintenance of the inner equipment box. At the same time, the outer box is equipped with reinforcing mechanisms on all side walls except the box door, so that the structural rigidity of the stress side walls is enhanced when the outer box is clamped or supported by the positioning module, effectively resisting the local deformation caused by clamping and supporting forces, and ensuring the shape stability and sealing reliability of the outer box after long-term fixation in the positioning space.

[0014] Furthermore, the top of the outer casing is covered with a top box, which has a second chamber inside. The bottom of the outer casing is provided with a bottom box, which has a third chamber inside. The first chamber communicates with the second chamber and the third chamber respectively. A switch cabinet electrically connected to the inner casing of the equipment is installed in the second chamber. A heat dissipation mechanism is installed in the third chamber. Multiple heat dissipation holes communicating with the third chamber are opened on the side wall of the bottom box. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to its embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of protection of the invention.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] In this invention, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0022] like Figures 1-6 As shown, an embodiment of the present invention provides a distribution box installation structure, including a mounting base 1 and a positioning device 4. An adjusting bracket 2 is mounted on the mounting base 1 via a drive module 3, and a power cabinet 21 electrically connected to the distribution box is embedded in the adjusting bracket 2. The positioning device 4 is mounted on the adjusting bracket 2 and includes at least two positioning components. The positioning components can slide relative to the adjusting bracket 2. One or more positioning modules 411 are provided on the positioning components, and the positioning modules 411 located on different positioning components enclose a positioning space for fixing the distribution box.

[0023] The aforementioned distribution box installation structure, by providing a drive module 3, enables the adjusting bracket 2 to swing relative to the mounting base 1, thereby causing the power cabinet 21 embedded in the adjusting bracket 2 and the distribution box fixed on the adjusting bracket 2 to rotate together, facilitating installation, wiring, maintenance, and angle adjustment. At the same time, the positioning device 4 uses at least two positioning components that can slide relative to the adjusting bracket 2, and sets positioning modules 411 on the positioning components, so that the positioning modules 411 on different positioning components form a positioning space for fixing the distribution box, thereby adapting to distribution boxes of different specifications and achieving rapid positioning and reliable fixing, improving installation flexibility and applicability.

[0024] In one embodiment, the outgoing end of the power cabinet 21 is electrically connected to the incoming end of the distribution box via a flexible cable or busbar, and the length of the flexible cable or busbar is sufficient to allow for the swing of the adjustment bracket 2.

[0025] like Figure 1 , Figure 4 and Figure 6As shown, in one embodiment, the drive module 3 includes a bearing 31, a connecting plate 32, a drive gear 33, and a driven gear 34 meshing with the drive gear 33. The bearing 31 is mounted on the mounting base 1, and a first rotating shaft and a second rotating shaft are rotatably inserted on the bearing 31. The drive gear 33 is sleeved on the first rotating shaft, and the driven gear 34 is sleeved on the second rotating shaft. The connecting plate 32 is mounted on the side wall of the adjusting bracket 2, and the second rotating shaft is fixed on the connecting plate 32. When the driving gear 33 rotates, it can drive the connecting plate 32 and the adjusting bracket 2 to swing relative to the mounting base 1 through meshing with the driven gear 34, thereby realizing the angle flipping of the adjusting bracket 2 and the distribution box. At the same time, the first rotating shaft and the second rotating shaft are respectively rotatably inserted into the bearing seat 31, so that the driving gear 33 and the driven gear 34 can obtain stable rotational support, ensuring the smoothness and load-bearing capacity of the gear meshing transmission. In addition, the connecting plate 32 is directly connected to the side wall of the adjusting bracket 2, so that the force transmission path between the gear transmission and the adjusting bracket 2 is short and the structure is compact, which is conducive to improving the reliability of the flipping action and the overall stability of the installation structure.

[0026] In this embodiment, one end of the first rotating shaft extends to the outside of the shaft seat 31 and is connected to an operating handle. When the operating handle is rotated, it drives the first rotating shaft and the drive gear 33 to rotate. Alternatively, one end of the first rotating shaft is connected to a drive motor, and the output shaft of the drive motor is connected to the first rotating shaft in a transmission connection.

[0027] like Figure 1 and Figure 4 As shown, in one embodiment, the drive module 3 further includes a locking member 35, which includes a pawl and a ratchet. The ratchet is disposed on the circumferential edge of the driven gear 34, and the pawl is rotatably disposed on the bearing 31. One end of the pawl meshes with the ratchet, and the other end of the pawl is connected to an elastic element. The elastic element causes the pawl to tend to abut against the ratchet. When the drive gear 33 drives the driven gear 34 to rotate in the forward direction, the ratchet pushes the pawl to overcome the elastic force of the elastic element and lift it up. When the drive gear 33 stops driving, the pawl is engaged in the tooth groove of the ratchet under the action of the elastic element, preventing the driven gear 34 from rotating in the reverse direction, thereby locking the adjustment bracket 2 at the current angle. The adjustment bracket 2 can automatically lock at the current angle after being flipped into place, preventing the distribution box from rotating due to its own weight or external force without additional operation, thus improving the stability and safety of the installation structure after flipping. At the same time, the locking part 35 directly cooperates with the driven gear 34, and the locking force is transmitted through gear meshing. The force path is short, the structure is compact, and the unlocking operation is simple, which helps to improve the convenience of installation and maintenance.

[0028] Furthermore, the pawl is connected to an unlocking lever, which extends to the outside of the shaft seat 31. By operating the unlocking lever, the pawl overcomes the elastic force of the elastic element, lifts up, and disengages from the ratchet teeth, thereby releasing the lock.

[0029] Preferably, the elastic element is a compression spring, and a spring seat is provided on the shaft seat 31. One end of the compression spring abuts against the spring seat, and the other end abuts against the end of the pawl away from the ratchet tooth.

[0030] In the second embodiment, the locking member 35 includes a pin and multiple pin holes disposed on the end face of the driven gear 34. The multiple pin holes are evenly distributed along the circumference of the driven gear 34. A guide seat is provided on the shaft seat 31, and the pin slides through the guide seat. One end of the pin can be inserted into or removed from the pin hole. When the driven gear 34 rotates to the target angle, the pin aligns with the corresponding pin hole. Inserting the pin into the pin hole locks the driven gear 34 relative to the shaft seat 31, and the adjusting bracket 2 remains at the current angle. Pulling out the pin releases the lock, allowing the driven gear 34 to rotate in the opposite direction. Through the cooperation of the pin and multiple pin holes, the adjusting bracket 2 can be locked at multiple preset angle positions. After locking, the connection is reliable and not easily loosened by vibration or external force. At the same time, the cooperation structure of the pin and pin holes is simple, easy to process, and the unlocking operation is intuitive, making it suitable for installation scenarios that require multiple angle fixations.

[0031] In the third embodiment, the locking member 35 includes a friction block and a friction surface disposed on the end face of the driven gear 34. A guide groove is provided on the bearing 31, and the friction block is slidably disposed within the guide groove. A friction material layer is provided on the side of the friction block facing the friction surface. The friction block is connected to a clamping screw, which is rotatably disposed on the bearing 31. Rotating the clamping screw pushes the friction block to press against the friction surface, locking the driven gear 34 relative to the bearing 31 through friction, thus maintaining the adjusting bracket 2 at the current angle. Reversing the rotation of the clamping screw moves the friction block away from the friction surface, thereby releasing the lock. Through the clamping engagement between the friction block and the friction surface, the adjusting bracket 2 can achieve stepless locking at any angle position, unrestricted by tooth position or pin hole position, making angle adjustment more flexible. Simultaneously, the friction locking method is shock-free during locking and unlocking, operates smoothly, and has a compact structure, making it suitable for installation scenarios requiring continuous stepless angle adjustment.

[0032] like Figure 6 As shown, in one embodiment, the adjusting bracket 2 is equipped with a fixed frame plate 22. The fixed frame plate 22 has first disassembly seats 23 at both its upper and lower ends, and a second disassembly seat 24 is located between the two first disassembly seats 23. The first disassembly seats 23 have horizontal connecting modules, and the second disassembly seat 24 has vertical connecting modules. The horizontal and vertical connecting modules are detachably connected to the outer wall of the power cabinet 21. This ensures that when the adjusting bracket 2 is flipped, the power cabinet 21 moves along with it without loosening or shifting, and that the power cabinet 21 can be detached independently from the adjusting bracket 2.

[0033] like Figure 2As shown, in one embodiment, the positioning device 4 further includes a receiving plate 42 and two side plates 43. The receiving plate 42 is connected between the two side plates 43 and is used to support the distribution box. The side plates 43 are mounted on the adjusting bracket 2, and each side plate 43 is provided with a lifting guide rail 431. The positioning component is slidably mounted on the lifting guide rail 431. This provides the distribution box with multiple supports, including bottom support and side limit, within the positioning space, ensuring the stability and load-bearing reliability of the distribution box after it is fixed. At the same time, the positioning component can slide up and down along the lifting guide rail 431, allowing the height of the positioning space to be adjusted according to the specifications of the distribution box, thereby adapting to distribution boxes of different sizes and facilitating the installation and removal of the distribution box, improving the versatility and ease of operation of the positioning device 4.

[0034] Specifically, the lifting guide rail 431 is arranged in a vertical direction.

[0035] like Figure 2 and Figure 3 As shown, in one embodiment, the positioning component includes a sliding seat 412 and one or more auxiliary modules 413 disposed on the sliding seat 412. A first transverse guide rail 414 is disposed on the sliding seat 412. The positioning module 411 is slidably mounted on the first transverse guide rail 414. The number of positioning modules 411 and the number of auxiliary modules 413 are both two and correspond one-to-one. A pad 4131 is retractably disposed on the auxiliary module 413. The positioning module 411 includes a first driving member 4111, a swing arm 4112 and a pressure plate 4113. The output end of the first driving member 4111 is connected to one end of the swing arm 4112, and the other end of the swing arm 4112 is fixedly connected to the pressure plate 4113. The pad 4131 and the pressure plate 4113 cooperate to clamp at the corner between adjacent side walls of the distribution box. The pad 4131 and the pressure plate 4113 work together to form a clamp at the corner of the distribution box, thereby simultaneously limiting the distribution box in the direction of the adjacent side walls, so that the distribution box can obtain a more reliable corner positioning and anti-detachment effect in the positioning space; at the same time, the pad 4131 is telescopic, which can adapt to the corner size of different specifications of distribution boxes. The first driving member 4111 drives the swing arm 4112 to drive the pressure plate 4113 to move, making the clamping and releasing operation simple and facilitating the quick assembly and disassembly of the distribution box.

[0036] Specifically, the first transverse guide rail 414 is set in a horizontal direction.

[0037] Preferably, the first driving member 4111 is an electric push rod or cylinder, the output end of which is hinged to one end of the swing arm 4112, the middle part of the swing arm 4112 is rotatably mounted on the sliding seat 412 via a pin, and the other end of the swing arm 4112 is fixedly connected to the pressure plate 4113.

[0038] like Figure 5As shown, in one embodiment, the positioning device 4 further includes a centering frame plate 44, a turntable 45, and a rotating module 451. The centering frame plate 44 is mounted on the adjusting bracket 2. The turntable 45 is located at the center of the centering frame plate 44. A third rotating shaft is rotatably mounted on the turntable 45. The rotating module 451 includes a rotating arm 4511 and two pull rods 4512. The rotating arm 4511 is inserted into the third rotating shaft. One end of the rotating arm 4511 is connected to one of the pull rods 4512, and the other end of the rotating arm 4511 is connected to the other pull rod 4512. There are two positioning components. The pull rods 4512 are connected to the positioning components and the two correspond one-to-one. The rotating module 451 enables the two positioning components to move closer or further apart synchronously, thereby clamping and fixing the distribution box on the adjusting bracket 2. This ensures that the distribution box is located in the center of the positioning space after it is fixed, avoiding box displacement caused by individual adjustment of the positioning components. At the same time, the rotating arm 4511 can drive the two pull rods 4512 to move simultaneously by rotating around the third axis, keeping the adjustment actions of the two positioning components linked and synchronized. This simplifies the centering operation steps and improves the accuracy and efficiency of the distribution box positioning.

[0039] like Figure 5 As shown, in one embodiment, a second transverse guide rail 441 is also provided on both sides of the centering frame plate 44; the positioning assembly includes a second drive member 415, a centering plate 416, and a slider 417 slidably mounted on the second transverse guide rail 441. The second drive member 415 is mounted on the centering frame plate 44, and the centering plate 416 is fixedly mounted on the slider 417. The output end of the second drive member 415 is in transmission cooperation with the centering plate 416. A plurality of positioning modules 411 are provided on the centering plate 416. The positioning modules 411 are configured as centering rods 4114 protruding from the centering plate 416. The plurality of centering rods 4114 are spaced apart and are used to abut against the side wall of the distribution box. The two centering plates 416 can move synchronously along the second transverse guide rail 441, thereby applying a centering thrust to the distribution box from both sides, so that the distribution box is automatically centered on the adjusting bracket 2; at the same time, multiple spaced centering rods 4114 can simultaneously abut from multiple positions on the side wall of the distribution box, making the centering force distribution more uniform, avoiding single-point force causing box tilting or deformation, and improving the centering accuracy and stability of the distribution box; the second driving component 415 drives the centering plates 416 to move along the guide rail, making the centering action smooth and controllable, and easy to adapt to distribution boxes of different widths.

[0040] Specifically, the second transverse guide rail 441 is set in a horizontal direction.

[0041] Preferably, the second driving component 415 is an electric push rod or a cylinder, the output end of which is connected to the centering plate 416 to push the centering plate 416 to move along the second transverse guide rail 441.

[0042] In this embodiment, the centering rod 4114 is a cylindrical rod.

[0043] like Figure 7 As shown, a distribution box includes an outer box 5 fixed in a positioning space. The outer box 5 has a first chamber, and an inner equipment box 6 electrically connected to a power cabinet 21 is installed in the first chamber. An openable and closable door is provided on one side wall of the outer box 5, and reinforcing mechanisms are provided on the other side walls of the outer box 5. The reinforcing mechanisms are used to enhance the structural rigidity of the outer box 5 when it is clamped or supported by the positioning module 411.

[0044] The aforementioned distribution box, by setting a first chamber inside the outer box 5 and installing the inner box 6 inside it, forms an inner and outer layered structure inside the distribution box, which facilitates the independent installation and maintenance of the inner box 6. At the same time, the outer box 5 is equipped with reinforcing mechanisms on all side walls except the box door, so that when the outer box 5 is clamped or supported by the positioning module 411, the structural rigidity of the stressed side walls is enhanced, effectively resisting the local deformation caused by clamping and supporting forces, and ensuring the shape stability and sealing reliability of the outer box 5 after long-term fixation in the positioning space.

[0045] In the first embodiment, the reinforcing mechanism includes multiple reinforcing ribs, which are respectively disposed on the sidewalls of the outer casing 5 and arranged crosswise in the transverse and longitudinal directions. The two ends of the reinforcing ribs extend to the edges of the sidewalls of the outer casing 5. This provides structural reinforcement to the sidewalls of the outer casing 5 in multiple directions, effectively dispersing the local stress generated when the positioning module 411 clamps the casing, and improving the deformation resistance of the sidewalls. At the same time, the two ends of the reinforcing ribs extending to the edges of the sidewalls form a closed stress-bearing frame together with the edges of the sidewalls, further enhancing the overall structural rigidity of the outer casing 5.

[0046] In the second embodiment, the reinforcing mechanism includes a reinforcing plate and multiple supporting bosses. The reinforcing plate is fitted onto the side wall of the outer casing 5, and the multiple supporting bosses are spaced apart between the reinforcing plate and the side wall of the outer casing 5. One end of each supporting boss is connected to the reinforcing plate, and the other end is connected to the side wall of the outer casing 5. This creates a cavity structure between the reinforcing plate and the side wall, which not only improves the bending stiffness of the side wall but also acts as a buffer, reducing the direct impact of clamping forces on the side wall. The reinforcing plate's fit against the side wall increases the stress-bearing area, preventing stress concentration and further improving the structural stability of the outer casing 5 when clamped or supported.

[0047] like Figure 7As shown, in one embodiment, the top of the outer casing 5 is covered by a top casing 7, which contains a second chamber. The bottom of the outer casing 5 is provided with a bottom casing 8, which contains a third chamber. The first chamber communicates with both the second and third chambers. A switch cabinet 9, which is electrically connected to the inner casing 6, is installed in the second chamber. A heat dissipation mechanism is installed in the third chamber. Multiple heat dissipation holes 81 communicating with the third chamber are provided on the side wall of the bottom casing 8. This allows the distribution box to form an expanded installation space based on the original first chamber, facilitating the separate arrangement of the switch cabinet 9 and the heat dissipation mechanism, and improving space utilization. At the same time, the communication between the first, second, and third chambers facilitates cable routing and electrical connections between the chambers. The heat dissipation mechanism is located in the bottom casing 8 and communicates with the outside through the heat dissipation holes 81, allowing heat in the first chamber to be discharged downwards through the third chamber, preventing heat accumulation around the inner casing 6, and improving the heat dissipation effect and operational reliability of the distribution box.

[0048] In this embodiment, the heat dissipation mechanism includes a cooling fan and multiple heat dissipation fins. The multiple heat dissipation fins are spaced apart in the third chamber, and the cooling fan is located on one side of the heat dissipation fins, with the airflow direction of the cooling fan facing the heat dissipation hole 81. By increasing the heat dissipation area in the third chamber through the heat dissipation fins, the heat transferred from the first chamber to the third chamber can be quickly conducted to the surface of the heat dissipation fins, and then the cooling fan blows the heat from the surface of the heat dissipation fins out of the bottom box 8 through the heat dissipation hole 81.

[0049] 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.

[0050] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
