Description

Technical Field

[0001] This invention relates to the field of power transmission equipment technology, specifically to a busbar connector and its busbar structure. Background Technology

[0002] In the field of electrical engineering, busbar trunking is a core electrical device for transmitting high currents. A busbar trunking system typically consists of multiple busbar trunking units connected by connectors to meet various wiring requirements. As a key component of the busbar trunking system, the connector's core function is to achieve precise docking and stable conductivity between the busbars of multiple busbar trunking units and the connector's conductive components. However, existing technologies have several shortcomings: Firstly, the busbar dimensions of different busbar trunking specifications vary, and traditional connectors are mostly custom-made, making it impossible to flexibly adjust the spacing of conductive components according to the busbar dimensions, resulting in poor versatility and increased construction costs and spare parts inventory pressure. Secondly, the connection tightness between the conductive components of traditional connectors and the busbars is difficult to control precisely. During long-term use, vibration, loose threads, etc., can easily lead to increased contact gaps, increased contact resistance, and safety hazards such as overheating and arcing. Furthermore, traditional connectors are mostly adjusted using a single fixed adjustment method, unable to achieve flexible switching between overall synchronous adjustment and independent adjustment of individual components, resulting in insufficient operational convenience and a lack of real-time detection methods for connection tightness, making it difficult to ensure the stability and safety of power transmission. Therefore, this paper proposes a busbar trunking connector and its busbar trunking structure. Summary of the Invention

[0003] The purpose of this invention is to provide a busbar connector and its busbar structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a busbar trunking connector, comprising a connector mounting plate, wherein a movable groove is provided on the outside of the connector mounting plate, two upright plates are fixedly connected to the connector mounting plate, and a first threaded rod is rotatably connected inside the upright plate. The first threaded rod is connected to multiple sliding connecting seats through an adjustment structure, and a conductive copper plate is installed at the bottom of the sliding connecting seats.

[0005] The adjustment structure includes a limiting groove, which is opened on the outside of the sliding connecting seat. Two threaded clamping plates are slidably connected inside the limiting groove. The external threads of the threaded clamping plates are connected to the internal threads of the first threaded rod. A pushing structure is installed on the outside of the threaded clamping plates. The pushing structure is used to push the threaded clamping plates to connect or separate from the first threaded rod.

[0006] Preferably, a second threaded rod is connected through the outside of the sliding connecting seat. The first threaded rod is located on the left side of the sliding connecting seat, and the second threaded rod is located on the right side of the sliding connecting seat. The threads of the first threaded rod and the second threaded rod are opposite. Both the first threaded rod and the second threaded rod are movably connected to the sliding connecting seat through an adjustment structure. A knob is fixedly connected to one end of both the first threaded rod and the second threaded rod.

[0007] Preferably, the first threaded rod has multiple protruding bladders integrally formed inside the threaded groove, and the first and second threaded rods have insertion slots opened inside through a rotating structure. The insertion slots are connected to the protruding bladders, and the air inlet of the insertion slots is connected to a [missing information].

[0008] Preferably, the rotating structure includes a rotating roller, which is rotatably connected to the interior of the first threaded rod and the second threaded rod. A plurality of magnetic blocks are fixedly connected to the inner wall of the protruding bladder. The insertion slot is opened inside the rotating roller, and a magnetic positioning plate is inserted into the interior of the rotating roller.

[0009] Preferably, the connector mounting plate has folding outer covers hinged to both sides of its outer wall, and two side covers are fixedly connected to the bottom of the connector mounting plate.

[0010] Preferably, the pushing structure includes a fixing clamp, which is fixedly connected to the outside of the threaded clamp plate. Two magnetic bonding plates are connected to both sides of the fixing clamp. Every two threaded clamp plates and the fixing clamp form a group. The magnetic bonding plates on the outside of each group of fixing clamps are arranged opposite each other and in a Y shape.

[0011] Preferably, each set of magnetic bonding plates is fixedly connected to a guide plate, and each set of guide plates is fixedly connected to an elastic connecting plate at its top. A support rod is fixedly connected to the outside of the elastic connecting plate, and the support rod is connected to the elastic connecting plate on another set of guide plates.

[0012] Preferably, an elastic connecting seat is integrally formed at the middle position of the sliding connecting seat, and a resistive strain sensor is installed on the outside of the elastic connecting seat.

[0013] Preferably, guide grooves are provided on both sides of the inner wall of the movable groove, and a guide slider is fixedly connected to the outside of the sliding connecting seat, and the guide slider is slidably connected to the inside of the guide groove.

A single person can complete the operation, improving construction efficiency. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1, such as Figure 1 and Figure 9 As shown, this application discloses a busbar trunking connector, including a connector mounting plate 100. The connector mounting plate 100 has a movable groove 110 on its outer side. Two upright plates 101 are fixedly connected to the connector mounting plate 100. A first threaded rod 102 is rotatably connected inside the upright plate 101. The first threaded rod 102 is connected to a plurality of sliding connecting seats 103 through an adjustment structure. A conductive copper plate 104 is installed at the bottom of the sliding connecting seat 103.

[0030] The adjustment structure includes a limiting groove 105, which is opened on the outside of the sliding connecting seat 103. Two threaded clamping plates 106 are slidably connected inside the limiting groove 105. The external threads of the threaded clamping plates 106 are connected to the internal threads of the first threaded rod 102. A pushing structure is installed on the outside of the threaded clamping plates 106. The pushing structure is used to push the threaded clamping plates 106 and the first threaded rod 102 to connect or separate.

[0031] A busbar trunking structure includes a second busbar trunking 901 and a first busbar trunking 900. A busbar 902 is installed at one adjacent end of the second busbar trunking 901 and the first busbar trunking 900. A plurality of conductive copper plates 104 are inserted into the interior of the busbar 902 and are attached to the side wall of the busbar 902.

[0032] Specifically, during the use and installation of the connector, when facing different busbars and different busbars 902, the operator adjusts the approximate position of the conductive copper plate 104. The operator then pushes the structure to separate the threaded clamp 106 within the limiting groove 105. At this point, the threaded clamp 106 is completely disengaged from the first threaded rod 102. Then, the operator manually pushes the sliding connecting seat 103, causing it to slide along the guide groove in the moving groove 110. This causes the bottom conductive copper plate 104 to quickly move to a position approximately aligned with the busbar 902, thus completing the initial alignment. Then, the staff pushes the structure to bring the two threaded clamps 106 closer to each other in the limiting groove 105 until the external thread of the threaded clamp 106 is fully engaged with the internal threads of the first threaded rod 102 and the second threaded rod 200. Then, the knob 109 at the end of the first threaded rod 102 is rotated to drive the sliding connecting seat 103 to move precisely using the thread transmission, so that the conductive copper plate 104 is tightly attached to the side wall of the busbar 902. If a single conductive copper plate 104 needs to be finely adjusted in the opposite direction, the threaded clamp 106 of the corresponding sliding connecting seat 103 can be loosened, and the second threaded rod 200 with the reverse thread can be rotated to achieve independent adjustment.

[0033] like Figures 1-3 As shown, folding outer covers 500 are hinged to both sides of the outer wall of the connector mounting plate 100, and two side covers 501 are fixedly connected to the bottom of the connector mounting plate 100.

[0034] Specifically, during installation, workers can fold up and open the outer cover 500 to clearly observe the position of the moving slot 110, sliding connector 103, and conductive copper plate 104, making it convenient to align and connect the busbars 902 of the busbar trough.

[0035] like Figures 4-10 As shown, the pushing structure includes a fixing clamp 107, which is fixedly connected to the outside of the threaded clamp plate 106. Two magnetic bonding plates 108 are connected to both sides of the fixing clamp 107. Each pair of threaded clamp plates 106 and fixing clamp 107 forms a group. The magnetic bonding plates 108 on the outside of each group of fixing clamps 107 are arranged opposite each other and in a Y shape.

[0036] Specifically, during use, the operator first clarifies the adjustment requirements. For example, if it is necessary to quickly move the sliding connector 103 or precisely adjust the position of the conductive copper plate 104, observe the initial state of the fixing clamp 107 and the magnetic bonding plate 108. If the magnetic bonding plate 108 is in a separated state, it indicates that the threaded clamp 106 is not engaged with the first threaded rod 102 or the second threaded rod 200. If it is in an adsorbed state, it is engaged. When it is necessary to quickly move the sliding connector 103, the operator pinches the two sets of opposing fixing clamps 107 and gently pulls them to both sides. Since the magnetic bonding plates 108 are Y-shaped and opposite each other, the pulling force will cause the two sets of magnetic bonding plates 108 to overcome the adsorption force and separate, thereby causing the threaded clamp 106 connected to the fixing clamp 107 to slide in the opposite direction within the limiting groove 105. Finally, the threaded clamp 106 is completely disengaged from the threaded rod. At this time, the sliding connector 103 can be manually pushed along the moving groove 110 to quickly adjust its position without being constrained by the threaded rod.

[0037] Furthermore, when precise adjustment is required, the operator releases the tension on the fixing clamp 107 or gently presses the fixing clamp 107 towards the center. The two sets of Y-shaped magnetic bonding plates 108 attract each other due to their opposite magnetic poles, automatically moving towards the center and fitting tightly. This process causes the two sets of threaded plates 106 to slide towards each other in the limiting groove 105 until the external thread of the threaded plate 106 is fully engaged with the internal thread of the first threaded rod 102. Once engaged, the first threaded rod 102 can be used for precise adjustment. After the magnetic bonding plate 108 is attracted, it will form a stable locking state to prevent the threaded plate 106 from accidentally separating during the adjustment process. The operator can gently pull the fixing clamp 107 to confirm the adsorption is firm. Then, the operator can rotate the knob 109 to drive the threaded rod to rotate, using the threaded transmission to achieve precise displacement between the sliding connecting seat 103 and the conductive copper plate 104.

[0038] like Figure 10 As shown, each set of magnetic bonding plates 108 is fixedly connected to a guide plate 600, and each set of guide plates 600 is fixedly connected to a top elastic connecting plate 601. A support rod 602 is fixedly connected to the outside of the elastic connecting plate 601, and the support rod 602 is connected to the elastic connecting plate 601 on another set of guide plates 600.

[0039] Specifically, during use, the staff first confirms the initial state of the pushing structure. If the magnetic bonding plate 108 is attached, it means that the threaded clamping plate 106 and the first threaded rod 102 are separated, which means they are not engaged. The subsequent switching can be done according to the adjustment requirements.

[0040] Specifically, when the sliding connecting seat 103 needs to be moved quickly, the operator presses the support rod 602 downwards by hand. The pressure is transmitted through the support rod 602 to the elastic connecting plates 601 on both sides. The elastic connecting plates 601 undergo elastic deformation, which drives the guide plate 600 fixed thereto to move synchronously. Since the guide plate 600 is fixed to the magnetic bonding plate 108 and the magnetic bonding plate 108 is Y-shaped and opposite to each other, the guide plate 600 will convert the downward pressure into a horizontal separation force, pushing the two sets of magnetic bonding plates 108 to overcome the adsorption force and separate to both sides. This will cause the fixing clamp 107 and the threaded clamp 106 connected to the magnetic bonding plate 108 to slide in the opposite direction in the limiting groove 105. Finally, the threaded clamp 106 is completely disengaged from the thread of the threaded rod. At this time, the sliding connecting seat 103 can be manually adjusted quickly along the moving groove 110.

[0041] Furthermore, when precise adjustment is required, the operator releases the pressure on the support rod 602 and can pull the support rod 602 upwards. After the elastic connecting plate 601 loses pressure, it returns to its original state with the upward pulling force, causing the guide plate 600 to reset. Due to the attraction of opposite magnetic poles, the two sets of Y-shaped magnetic bonding plates 108 automatically move towards the center and fit tightly together. At the same time, the threaded clamping plate 106 slides towards each other in the limiting groove 105 until the external thread of the threaded clamping plate 106 is fully engaged with the internal thread of the first threaded rod 102. This makes it convenient for the operator to make quick adjustments.

[0042] like Figure 8 As shown, an elastic connecting seat 700 is integrally formed at the middle position of the sliding connecting seat 103, and a resistive strain sensor 701 is installed on the outside of the elastic connecting seat 700.

[0043] Specifically, the operator adjusts the position of the sliding connecting seat 103 using the first threaded rod 102, causing the conductive copper plate 104 to move closer to and fit against the busbar 902 of the busbar trunking. At this time, the elastic connecting seat 700 undergoes elastic deformation due to the compression between the conductive copper plate 104 and the busbar 902. The degree of deformation increases with the increase of the fitting pressure. The resistive strain sensor 701 senses the deformation of the elastic connecting seat 700 in real time, converts the deformation into a resistance change signal, and transmits it to the detection equipment. The operator reads the resistance value through the equipment and, in conjunction with a preset standard, determines the tightness of the fit between the conductive copper plate 104 and the busbar 902. If the resistance value is within the standard range, it indicates that the bonding pressure meets the standard. If the resistance value is too low, it means that the deformation is insufficient, and the sliding connector 103 needs to be finely adjusted to increase the pressure. If the resistance value is too high, it means that the deformation is too large, and the pressure should be adjusted appropriately to avoid excessive squeezing and damage to the components. During the operation of the busbar system, the staff can periodically check the real-time data of the resistive strain sensor 701 through the testing equipment. If the resistance value fluctuates abnormally, such as gradually decreasing, it means that the conductive copper plate 104 and the busbar 902 may be loose. The machine needs to be stopped in time for inspection and re-tightening to avoid problems such as overheating and decreased conductivity caused by poor contact.

[0044] like Figures 1-8 As shown, guide grooves are provided on both sides of the inner wall of the movable groove 110, and a guide slider 800 is fixedly connected to the outside of the sliding connecting seat 103. The guide slider 800 is slidably connected to the inside of the guide groove.

[0045] Specifically, when the staff pushes the structure to separate the threaded clamp 106 from the threaded rod, and then manually pushes the sliding connector 103, the guide slider 800 will slide smoothly along the trajectory of the guide groove, limiting the movement direction of the sliding connector 103, that is, moving parallel in the front-back direction, preventing it from shifting left or right, tilting or twisting in the moving groove 110, ensuring that the conductive copper plate 104 at the bottom can be accurately aligned with the approximate docking area of ​​the busbar 902, and quickly completing the initial alignment.

[0046] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: Compared with the prior art, in this embodiment, the overall guiding structure of the moving slot 110 and the sliding connecting seat 103, combined with the engagement and disengagement switching function of the adjustment structure, solves the problem that traditional connectors can only be adjusted individually or require customized adaptation. When facing busbars and busbars 902 of different sizes, the conductive copper plate 104 can be quickly and coarsely aligned by separating the threaded clamp plate 106, and then precise fine adjustment can be achieved by threaded engagement. There is no need to replace the connector, which can adapt to various specifications of busbars 902. Moreover, with the help of the threaded transmission structure of the first threaded rod 102, compared with the coarse adjustment of the traditional pressing rod and multiple guide slots, the millimeter-level precise displacement of the conductive copper plate 104 can be achieved, ensuring a tight fit with the busbar 902. At the same time, the adjustment mode can be quickly switched by pushing the structure, avoiding the tedious process of disassembling and adjusting each component of the traditional connector. A single person can complete the operation, improving construction efficiency.

[0047] Example 2: Considering that in actual use, there are often situations where the busbar 902 has inconsistent dimensions, uneven spacing, or misalignment, using a single first threaded rod 102 can only achieve unidirectional displacement of one or more sliding connecting seats 103, and cannot adjust the bidirectional displacement of one or more sliding connecting seats 103 as needed. When faced with bidirectional displacement, one can only loosen the threaded connection between a portion of the sliding connecting seats 103 and the first threaded rod 102, adjust the position of the other sliding connecting seats 103, and then restore the connection state. This is cumbersome and simplistic. To address the above technical problems, this application proposes the following technical solution:

[0048] like Figures 3-4 As shown, a second threaded rod 200 is connected through the outside of the sliding connecting seat 103. The first threaded rod 102 is located on the left side of the sliding connecting seat 103, and the second threaded rod 200 is located on the right side of the sliding connecting seat 103. The threads of the first threaded rod 102 and the second threaded rod 200 are opposite. Both the first threaded rod 102 and the second threaded rod 200 are movably connected to the sliding connecting seat 103 through an adjustment structure. A knob 109 is fixedly connected to one end of both the first threaded rod 102 and the second threaded rod 200.

[0049] Specifically, during use, the operator first pushes the structure to engage the threaded plates 106 of all sliding connectors 103 with the first threaded rod 102 and the second threaded rod 200. If it is necessary to reduce the spacing between the conductive copper plates 104, the knobs 109 on both sides are rotated clockwise simultaneously. The first threaded rod 102 on the left moves the sliding connector 103 to the right due to its forward thread, while the second threaded rod 200 on the right moves the sliding connector 103 to the left due to its reverse thread. All the conductive copper plates 104 move closer together. If it is necessary to increase the spacing, the knobs 109 are rotated counterclockwise simultaneously. The threaded rods on both sides move the sliding connectors 103 to separate in the opposite direction, quickly adapting to the overall spacing requirements of the busbar 902.

[0050] Furthermore, when there are differences in the dimensions or spacing of some busbars 902, the operator first loosens the threaded clamp 106 of the corresponding sliding connecting seat 103 by pushing the structure, so that it is disengaged from the first threaded rod 102 and the second threaded rod 200. For example, the engagement with the first threaded rod 102 is retained, and the connection with the second threaded rod 200 is disconnected. If the conductive copper plate 104 needs to be moved to the right alone, the knob 109 of the first threaded rod 102 on the left is turned. If it needs to be moved to the left alone, the second threaded rod 200 is re-engaged and the corresponding knob 109 is turned. This achieves reverse fine adjustment of a single conductive copper plate 104 without affecting the position of other adjusted conductive copper plates 104.

[0051] Furthermore, when faced with complex situations such as misalignment or tilting of the busbar 902, the operator can fine-tune the left and right displacement of the sliding connector 103 by controlling the knobs 109 of the two threaded rods respectively. For example, after rotating the first threaded rod 102 to move the sliding connector 103 to the approximate position, the deviation can be corrected by fine-tuning the second threaded rod 200 to ensure that the conductive copper plate 104 is completely in contact with the side wall of the busbar 902, thereby improving the connection accuracy.

[0052] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: Compared with Embodiment 1, in this embodiment, by combining the reverse threads of the first threaded rod 102 and the second threaded rod 200, and in conjunction with the meshing and disengagement functions of the adjustment structure, the sliding connecting seat 103 can achieve bidirectional displacement to the left and right. This retains the overall synchronous adjustment while allowing for individual control of the left and right movement of a single sliding connecting seat 103, precisely adapting to complex scenarios such as misalignment and tilting of the busbar 902, and avoiding diverse docking requirements that cannot be addressed by unidirectional adjustment.

[0053] Example 3: Considering that when using the first threaded rod 102 and the second threaded rod 200, it is necessary to fix and limit the first threaded rod 102 and the second threaded rod 200 after installation, if vibration or rotation of the threaded rod occurs during long-term use, it may cause the first threaded rod 102 or the second threaded rod 200 to loosen the conductive copper plate 104 and the busbar 902. To address the above technical problems, this application proposes the following technical solution to solve the above technical problems:

[0054] like Figures 5-8 As shown, the first threaded rod 102 has multiple protruding bladders 300 integrally formed inside the threaded groove. The first threaded rod 102 and the second threaded rod 200 have insertion grooves 301 opened inside through a rotating structure. The insertion grooves 301 are connected to the protruding bladders 300. A valve 302 is connected at the air inlet position of the insertion grooves 301.

[0055] Specifically, during use, after the operator has adjusted the position of the sliding connecting seat 103 and the conductive copper plate 104 using the first threaded rod 102 and the second threaded rod 200, the operator can turn on the inflation device and connect it to the air inlet of the valve 302. Gas is injected into the insertion groove 301 through the valve 302. Since the insertion groove 301 is connected to multiple protruding bladders 300, the gas will enter the interior of each protruding bladder 300 evenly, causing the bladder to gradually expand and protrude from the surface of the threaded groove. The inflation continues until the protruding bladders 300 completely fill the gap between the threaded clamping plate 106 and the threaded rod. At this time, the threaded clamping plate 106 is limited by the expanded bladder and cannot slide along the threaded groove, thus locking the position of the sliding connecting seat 103 and the conductive copper plate 104.

[0056] Furthermore, after locking is completed, the operator closes valve 302 and disconnects the air pump. By gently turning knob 109, it is confirmed that the first threaded rod 102 or the second threaded rod 200 cannot rotate, ensuring that the expansion state of the protruding bladder 300 is stable. This achieves the locking effect of the first threaded rod 102 and the second threaded rod 200, preventing the first threaded rod 102 or the second threaded rod 200 from loosening due to vibration or other conditions. When using gas, no additional accessories such as bolts are needed. Reducing the use of bolts will reduce the overall weight of the connector and the pressure on the lifting parts. Alternatively, bolts can be used, but double-ended bolts can be tightened. However, this is more complicated, and the operator needs to carry more bolts for fixing during installation.

[0057] like Figures 5-7As shown, considering that during use, the gas inside the insertion slot 301 will gradually leak, and once leakage occurs, it will greatly reduce the stability of the first threaded rod 102 and the second threaded rod 200, in order to solve the above-mentioned technical problems, this application proposes the following technical solution:

[0058] like Figures 5-7 As shown, the rotating structure includes a rotating roller 400, which is rotatably connected to the inside of the first threaded rod 102 and the second threaded rod 200. Multiple magnetic blocks 402 are fixedly connected to the inner wall of the protruding bladder 300. An insertion groove 301 is opened inside the rotating roller 400, and a magnetic positioning plate 401 is inserted into the inside of the rotating roller 400.

[0059] Specifically, after continuously filling the insertion slot 301 with gas, the operator can also rotate the rotating roller 400 by rotating the valve 302. When the rotating roller 400 rotates, the magnetic positioning plate 401 inside the rotating roller 400 flips synchronously. When the magnetic pole of the magnetic positioning plate 401 is opposite to the magnetic pole of the magnetic block 402 on the inner wall of the protruding bladder 300, the two generate a repulsive force, pushing the protruding bladder 300 to expand outward until it fills the gap between the threaded clamping plate 106 and the threaded rod, thereby achieving the mechanical locking of the sliding connecting seat 103.

[0060] Furthermore, if the position of the conductive copper plate 104 needs to be readjusted, the operator rotates the valve 302 outside the rotating roller 400 in the opposite direction, causing the magnetic pole of the magnetic positioning plate 401 to flip to the same direction as the magnetic block 402. The two generate an attraction, pulling the protruding bladder 300 to retract and reset to be flush with the threaded groove. If gas was previously filled in, the valve 302 must be opened to release the gas before the magnetic reset is performed. Then the threaded clamp 106 returns to its active state and its position can be adjusted by the knob 109. The entire process does not require the operator to use additional tools to unlock, and the unlocking and locking are relatively convenient. There is no need to disassemble or install parts, which improves the operator's work efficiency.

[0061] The technical solutions described in the above embodiments of this application have at least the following technical effects or advantages: Compared with Embodiment 2, in this embodiment, gas is injected into the insertion slot 301 through valve 302. The gas drives the protruding bladder 300 to expand, filling the gap between the threaded clamping plate 106 and the threaded rod, thus achieving the first physical limitation. Then, the magnetic positioning plate 401 is rotated by rotating roller 400, and the repulsive force generated by the opposite magnetic poles pushes the protruding bladder 300 to expand further and maintain a taut state, forming the second magnetic locking. The dual structures reinforce each other, and even if gas leaks, the magnetic repulsive force can still maintain the locking effect, ensuring the guide The copper plate 104 and the busbar 902 are in close contact for a long time, which greatly improves the stability of power transmission. Compared with the traditional method of fixing the threaded rod with bolts, nuts and other additional accessories, the built-in protruding bladder 300, the insertion slot 301 and the magnetic structure achieve locking. There is no need for staff to carry and install additional fasteners. On the one hand, it reduces the inventory and procurement costs of accessories. On the other hand, it avoids the tedious operation of alignment and tightening during bolt installation. At the same time, it reduces the extra weight brought by bolts and reduces the load-bearing pressure of the busbar hanging parts. It is especially suitable for complex construction scenarios such as high altitude and confined space, and greatly improves construction efficiency.

[0062] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
