Description

Technical Field

[0001] The invention relates to the technical field of tension wire clamps, and in particular to an anti-loosening tension wire clamp. Background Art

[0002] In the operation and maintenance of power transmission, it is usually necessary to use tension clamps to fix the transmission lines to withstand the tension of the transmission lines, and different types of tension clamps are selected according to the specific use of the lines;

[0003] At present, when the tension clamp is used for clamping, the tension clamp is mostly placed at a position where it needs to be fixed, and then fixed to the power line with bolts and nuts to complete the installation. Moreover, since the tension clamp is mostly used for high-altitude operations and there are a large number of bolts and nuts on the tension clamp, the workers are required to thread the nuts with the bolts one by one. This installation method is inefficient. At the same time, during the installation process, the workers are required to tighten the nuts on the handheld plate to determine the tightening strength of the bolts and nuts, which is more physically demanding when tightening the nuts. Therefore, an anti-loosening tension clamp is proposed to improve the installation efficiency of nuts and bolts, while improving the tightening strength of bolts and nuts and reducing the physical exertion of the workers. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides an anti-loosening and tension-resistant wire clamp, which improves the installation efficiency of nuts and bolts, while increasing the tightening strength of bolts and nuts and reducing the physical exertion of workers.

[0005] The technical solution adopted by the present invention to solve its technical problems is an anti-loosening and tension-resistant wire clamp, including a main body and a pressure plate, the pressure plate is located above the main body, and a plurality of groups of arc-shaped limit plates are provided on the side of the pressure plate away from the main body, and a plurality of groups of penetrating mounting holes are provided on both sides of the main body, and U-shaped bolts are provided in the plurality of groups of arc-shaped limit plates, and the lower ends of the U-shaped bolts pass through the mounting holes. It is characterized in that the lower ends of the U-shaped bolts are detachably connected with a fastening structure, and the fastening structure is located below the main body, and the fastening structure is used to drive the nut to rotate to fasten the main body and the pressure plate.

[0006] By adopting the above technical solution, the power transmission line is placed between the main body and the pressure plate, and the lower end of the U-shaped bolt is passed through the installation hole of the main body, so that the pressure plate and the main body are abutted, and the nut is placed in the fastening structure, and the lower end of the U-shaped bolt is inserted into the fastening structure. When the lower end of the U-shaped bolt is inserted into the fastening structure, the lower end of the U-shaped bolt corresponds to the screw hole of the nut, and the nut is driven to rotate by the fastening structure, so that the nut and the U-shaped bolt are threadedly connected, thereby improving the installation efficiency of the nut;

[0007] At the same time, the main body is squeezed by the fastening structure to bring the main body and the pressure plate closer together, thereby further improving the fastening strength between the main body and the pressure plate. When the main body and the pressure plate are close together through the fastening structure, the staff can turn the nut with a wrench to further fit the main body and the pressure plate together to improve the fastening between them. This installation method does not require the staff to manually take out the nut and tighten the lower end of the U-bolt one by one, thereby improving the installation efficiency and reducing the physical exertion of the staff.

[0008] Specifically, the fastening structure includes a support plate, the support plate is provided with two groups of slots, the slots correspond to the lower ends of the U-bolts, a sliding seat is slidably connected in the slots, a hexagonal slot is provided above the sliding seat, and a nut is provided in the hexagonal slot;

[0009] A driving structure is provided between the sliding seat and the slot, and the driving structure is used to drive the sliding seat to rotate.

[0010] By adopting the above technical solution, the nut is placed in the hexagonal groove. When the U-bolt needs to be tightened, the lower end of the U-bolt is passed through the mounting hole and corresponds to the nut in the hexagonal groove. The sliding seat is driven downward by the downward movement of the U-bolt, and the driving structure is opened when the sliding seat moves downward. The driving structure drives the sliding seat to rotate. When the sliding seat rotates, the hexagonal groove drives the nut to rotate. When the nut rotates, it is threadedly connected with the lower end of the U-bolt, so that the nut is threadedly connected with the U-bolt, thereby improving its installation efficiency.

[0011] Specifically, the driving structure includes a positioning groove arranged in the slot, one end of a torsion spring is fixedly connected in the positioning groove, and the other end of the torsion spring is fixedly connected to the outer side of the sliding seat.

[0012] By adopting the above technical solution, when the U-bolt moves downward, it corresponds to the nut in the hexagonal groove. By pressing the U-bolt downward, the sliding seat is driven to move downward. When the sliding seat moves downward, the sliding seat is driven to rotate by relying on the reset effect of the torsion spring. When the sliding seat rotates, the nut is driven to rotate by relying on the hexagonal groove. When the nut rotates, it is threadedly connected with the U-bolt, so that the nut and the U-bolt can be threadedly connected quickly.

[0013] Specifically, both sides of the support plate are provided with extrusion plates, a return spring is fixedly connected between the extrusion plate and the side close to the support plate, a horizontally arranged pin groove is arranged in the support plate, a horizontally arranged pin rod is fixedly connected to the side of the extrusion plate close to the support plate, and an end of the pin rod away from the extrusion plate passes through the pin groove and is located in the slot;

[0014] The lower ends of several groups of U-shaped bolts are all provided with tapered rods, the middle of the tapered rods are provided with a pin hole penetrating therethrough, the middle of the sliding seat is provided with a sliding hole penetrating therethrough, and the U-shaped bolts are slidably connected with the sliding hole.

[0015] By adopting the above technical scheme, during the process of threaded connection between the nut and the U-bolt, as the U-bolt continues to move downward, the tapered rod at the lower end of the U-bolt passes through the sliding hole of the sliding seat and is slidably connected to the sliding hole. When the tapered rod moves down to a certain position, the tapered rod is squeezed and contacted with the pin rod and drives the pin rod to move. When the pin rod moves, it drives the reset spring to accumulate force and drives the extrusion plate and the support plate to move away. When the tapered rod moves down to a certain position, the reset effect of the reset spring drives the pin rod to reset and move. When the pin rod resets and moves, the end of the pin rod away from the extrusion plate passes through the pin hole of the tapered rod and is slidably connected to the pin hole, thereby fixing the U-bolt, which is convenient for the subsequent approach of the main body to the pressure plate to improve the tightness between the main body and the pressure plate, and is also convenient for further tightening the nut and the U-bolt by a wrench.

[0016] When the U-bolts and nuts are tightened, manually move the extrusion plate and the support plate apart to disengage the pin rod from the pin hole of the tapered rod. At this time, the support plate can be removed to disengage the U-bolt from the support plate. At the same time, the sliding seat is rotated again to store force, and a new nut is placed in the hexagonal groove to facilitate the subsequent quick installation of the next set of U-bolts.

[0017] Specifically, a lifting structure is installed in the middle of the support plate, and the lifting structure is in compression contact with the lower surface of the main body.

[0018] By adopting the above technical scheme, when the U-bolt is threadedly connected with the nut and the pin rod fixes the U-bolt through the pin hole of the tapered rod, the main body is squeezed by the jacking structure to make the main body further close to the pressure plate to improve its tightness. After the jacking structure lifts the main body to a certain position, the staff needs to use a wrench to rotate the nut to further improve the tightness between the nut and the U-bolt to prevent loosening between the pressure plate and the main body in the later stage. At the same time, the jacking structure can reduce the physical exertion of the staff and alleviate their labor.

[0019] Specifically, a clamping block with a larger upper portion and a smaller lower portion is installed on the inner wall of the slot, and a clamping groove corresponding to the clamping block is provided on the top edge of the sliding seat. In an initial state, the clamping block is clamped with the clamping groove.

[0020] By adopting the above technical solution, the sliding seat can be fixed by relying on the clamping block and the clamping slot to prevent the sliding seat from rotating by relying on the reset effect of the torsion spring. The U-bolt is only pressed into contact with the nut when moving downward, and the sliding seat is driven downward by the nut. After the sliding seat moves downward to a certain position, the clamping block is disengaged from the clamping slot. At this time, the sliding seat is driven to rotate by relying on the reset effect of the torsion spring. When the sliding seat rotates, the nut is threadedly connected to the U-bolt, so as to facilitate the quick threaded connection of the nut and the U-bolt.

[0021] Specifically, the lifting structure includes an installation groove arranged in the middle of the support plate, a lifting cylinder is installed in the installation groove, an air supply channel is horizontally penetrated through the support block plate, one side of the air supply channel is connected to the lifting cylinder, and adjacent air supply channels are connected through an air supply pipe.

[0022] By adopting the above technical scheme, according to the actual number of U-bolts used, an appropriate amount of fastening structure is selected, and the lifting cylinders between adjacent support plates are connected through the air supply pipe and the air supply channel. After the U-bolt is threadedly connected with the nut, and the pin rod fixes the U-bolt through the pin hole of the tapered rod, a group of air supply channels are used to connect the air source. After the air source enters the lifting structure through the air supply channel, the air source is transported to several adjacent groups of lifting cylinders by the air supply pipe, so as to drive several groups of lifting cylinders to lift. When the lifting cylinder is lifted, the extrusion body and the pressure plate are close to each other, thereby improving the tightness between the body and the pressure plate. When the lifting cylinder lifts the body to a certain position, the staff needs to use a wrench to turn the nut, so as to further improve the tightness between the nut and the U-bolt, and prevent the pressure plate and the body from loosening in the later stage.

[0023] It should be pointed out that before connecting the air source, one end of the air supply channel away from the air source should be blocked by a blocking device to avoid air leakage when supplying air to all lifting cylinders at the same time; and it should be pointed out that the blocking device can be a valve or a plug bolt or other parts that are easy to disassemble.

[0024] Beneficial effects of the present invention:

[0025] (1) The anti-loosening and tension-resistant wire clamp described in the present invention places the power transmission line between the main body and the pressure plate, passes the lower end of the U-bolt through the mounting hole of the main body, so that the pressure plate and the main body are abutted against each other, and places the nut in the hexagonal groove. The U-bolt is pressed downward to drive the sliding seat downward. When the sliding seat moves downward, it drives the sliding seat to rotate by relying on the restoring effect of the torsion spring. When the sliding seat rotates, it drives the nut to rotate by relying on the hexagonal groove. When the nut rotates, it is threadedly connected with the U-bolt, so that the nut and the U-bolt can be threadedly connected quickly.

[0026] (2) The anti-loosening and tension-resistant wire clamp described in the present invention, after the U-bolt and the nut are threadedly connected, and the pin rod fixes the U-bolt through the pin hole of the tapered rod, it relies on a group of air supply channels to connect the air source. After the air source enters the jacking structure through the air supply channel, it drives several groups of jacking cylinders to lift. When the jacking cylinders are lifted, the extruded body and the pressure plate are close to each other, thereby improving the tightness between the body and the pressure plate. When the jacking cylinders lift the body to a certain position, the staff needs to use a wrench to rotate the nut, thereby further improving the tightness between the nut and the U-bolt, and preventing the pressure plate and the body from loosening in the later stage.

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] In order to improve the installation efficiency of nuts and bolts, and at the same time improve the fastening strength of bolts and nuts, and reduce the physical exertion of workers, as an embodiment of the present invention, Figure 1-3As shown, an anti-loosening and tension-resistant wire clamp described in the present invention includes a main body 1 and a pressure plate 2, wherein the pressure plate 2 is located above the main body 1, and a plurality of groups of arc-shaped limit plates 3 are provided on the side of the pressure plate 2 away from the main body 1, and a plurality of groups of penetrating mounting holes 4 are provided on both sides of the main body 1, and U-shaped bolts 5 are provided in the plurality of groups of arc-shaped limit plates 3, and the lower ends of the U-shaped bolts 5 pass through the mounting holes 4, and the lower ends of the U-shaped bolts 5 are detachably connected with a fastening structure, and the fastening structure is located below the main body 1, and the fastening structure is used to drive the nut 10 to rotate to fasten the main body 1 and the pressure plate 2.

[0040] When in use, the power transmission line is placed between the main body 1 and the pressing plate 2, and the lower end of the U-shaped bolt 5 is passed through the mounting hole 4 of the main body 1, so that the pressing plate 2 and the main body 1 are abutted against each other, and the nut 10 is placed in the fastening structure, and the lower end of the U-shaped bolt 5 is inserted into the fastening structure. When the lower end of the U-shaped bolt 5 is inserted into the fastening structure, the lower end of the U-shaped bolt 5 corresponds to the screw hole of the nut 10, and the nut 10 is driven to rotate by the fastening structure, so that the nut 10 is threadedly connected with the U-shaped bolt 5, thereby improving the installation efficiency of the nut 10;

[0041] At the same time, the main body 1 is squeezed by the fastening structure to bring the main body 1 and the pressure plate 2 closer together, thereby further improving the fastening strength between the main body 1 and the pressure plate 2. When the main body 1 and the pressure plate 2 are close together through the fastening structure, the staff can use a wrench to rotate the nut 10 to further fit the main body 1 and the pressure plate 2 together to improve the fastening between them. This installation method does not require the staff to manually remove the nut 10 and tighten the lower end of the U-bolt 5 one by one, thereby improving the installation efficiency and reducing the physical exertion of the staff.

[0042] In order to thread the nut 10 with the U-bolt 5, for example, Figure 1 , Figure 4 , Figure 5 As shown, the present invention also includes that the fastening structure includes a support plate 6, the support plate 6 is provided with two groups of slots 7, the slots 7 correspond to the lower ends of the U-bolts 5, a sliding seat 8 is slidably connected in the slots 7, a hexagonal slot 9 is provided above the sliding seat 8, and a nut 10 is provided in the hexagonal slot 9;

[0043] A driving structure is provided between the sliding seat 8 and the slot 7 , and the driving structure is used to drive the sliding seat 8 to rotate.

[0044] When in use, put the nut 10 into the hexagonal groove 9. When the U-bolt 5 needs to be tightened, the lower end of the U-bolt 5 is passed through the mounting hole 4 and corresponds to the nut 10 in the hexagonal groove 9. The sliding seat 8 is driven downward by the downward movement of the U-bolt 5. When the sliding seat 8 moves downward, the driving structure is opened, and the sliding seat 8 is driven to rotate by the driving structure. When the sliding seat 8 rotates, the nut 10 is driven to rotate by the hexagonal groove 9. When the nut 10 rotates, it is threadedly connected with the lower end of the U-bolt 5, so that the nut 10 is threadedly connected with the U-bolt 5, thereby improving its installation efficiency.

[0045] In order to facilitate the rotation of the sliding seat 8, for example, Figure 8 , Fig. 9 As shown, the present invention also includes that the driving structure includes a positioning groove 11 arranged in the slot 7, one end of a torsion spring 12 is fixedly connected in the positioning groove 11, and the other end of the torsion spring 12 is fixedly connected to the outer side of the sliding seat 8.

[0046] When in use, when the U-bolt 5 moves downward, it corresponds to the nut 10 in the hexagonal groove 9. By pressing the U-bolt 5 downward, the sliding seat 8 is driven downward. When the sliding seat 8 moves downward, the sliding seat 8 is driven to rotate by relying on the reset effect of the torsion spring 12. When the sliding seat 8 rotates, the nut 10 is driven to rotate by relying on the hexagonal groove 9. When the nut 10 rotates, it is threadedly connected with the U-bolt 5, so as to facilitate the quick threaded connection of the nut 10 and the U-bolt 5.

[0047] In order to fix the U-bolt 5, it is convenient to improve the tightness between the main body 1 and the pressure plate 2 later. Figure 3 , Figure 5 , Figure 7 , Figure 8 , Fig. 9 As shown, the present invention also includes that both sides of the support plate 6 are provided with an extrusion plate 13, a return spring 14 is fixedly connected between the extrusion plate 13 and the side close to the support plate 6, a horizontally arranged pin groove 15 is arranged in the support plate 6, and a horizontally arranged pin rod 16 is fixedly connected to the side of the extrusion plate 13 close to the support plate 6, and the end of the pin rod 16 away from the extrusion plate 13 passes through the pin groove 15 and is located in the slot 7;

[0048] The lower ends of several groups of the U-bolts 5 are all provided with tapered rods 17, the middle of the tapered rods 17 is provided with a pin hole 18 penetrating therethrough, the middle of the sliding seat 8 is provided with a sliding hole 19 penetrating therethrough, and the U-bolts 5 are slidably connected to the sliding hole 19.

[0049] When in use, in the process of threaded connection between nut 10 and U-bolt 5, as U-bolt 5 continues to move downward, tapered rod 17 at the lower end of U-bolt 5 passes through the sliding hole 19 of sliding seat 8 and is slidably connected with the sliding hole 19. When tapered rod 17 moves down to a certain position, tapered rod 17 is pressed and contacted with pin rod 16, and drives pin rod 16 to move. When pin rod 16 moves, it drives reset spring 14 to store force, and drives extrusion plate 13 and support plate 6 to move away. When tapered rod 17 moves down to a certain position, it relies on the reset effect of reset spring 14 to drive pin rod 16 to reset and move. When pin rod 16 resets and moves, the end of pin rod 16 away from extrusion plate 13 passes through pin hole 18 of tapered rod 17 and is slidably connected with pin hole 18, so as to fix U-bolt 5, so as to facilitate the subsequent approach of main body 1 and pressing plate 2 to improve the tightness between main body 1 and pressing plate 2, and at the same time facilitate the further tightening of nut 10 and U-bolt 5 by wrench.

[0050] When the U-bolt 5 and the nut 10 are tightened, the extrusion plate 13 and the support plate 6 are manually moved away from each other to disengage the pin rod 16 from the pin hole 18 of the tapered rod 17. At this time, the support plate 6 can be taken out to disengage the U-bolt 5 from the support plate 6. At the same time, the sliding seat 8 is rotated again to store force, and a new nut 10 is placed in the hexagonal groove 9, so as to facilitate the subsequent quick installation of the next set of U-bolts 5.

[0051] In order to make the main body 1 further close to the pressing plate 2 and improve the tightness thereof, for example, Figure 4 , Figure 6 As shown, the present invention also includes that a lifting structure is installed in the middle of the support plate 6, and the lifting structure is in compression contact with the lower surface of the main body 1.

[0052] When in use, when the U-bolt 5 is threadedly connected with the nut 10, and the pin rod 16 fixes the U-bolt 5 through the pin hole 18 of the tapered rod 17, the main body 1 is squeezed by the jacking structure to make the main body 1 further abut against the pressure plate 2 to improve its tightness. After the jacking structure lifts the main body 1 to a certain position, the staff needs to use a wrench to rotate the nut 10 to further improve the tightness between the nut 10 and the U-bolt 5 to prevent loosening between the pressure plate 2 and the main body 1 in the later stage. At the same time, the jacking structure can reduce the physical exertion of the staff and alleviate their labor.

[0053] For example, Figure 5 , Figure 8 , Fig. 9 As shown, the present invention also includes that a block 20 with a larger upper portion and a smaller lower portion is installed on the inner wall of the slot 7, and a slot 21 corresponding to the block 20 is provided on the top edge of the sliding seat 8. In the initial state, the block 20 is engaged with the slot 21.

[0054] When in use, the sliding seat 8 can be fixed by relying on the blocking block 20 and the blocking groove 21 to prevent the sliding seat 8 from rotating by relying on the reset effect of the torsion spring 12. The U-bolt 5 is only pressed and contacted with the nut 10 when moving downward, and the sliding seat 8 is driven downward by the nut 10. After the sliding seat 8 moves down to a certain position, the blocking block 20 is disengaged from the blocking groove 21. At this time, the sliding seat 8 is driven to rotate by relying on the reset effect of the torsion spring 12. When the sliding seat 8 rotates, the nut 10 is threadedly connected with the U-bolt 5, so as to facilitate the quick threaded connection of the nut 10 with the U-bolt 5.

[0055] In order to further improve the tightness between the nut 10 and the U-bolt 5, for example, Figure 4 , Figure 6 As shown, the present invention also includes that the lifting structure includes a mounting groove 22 arranged in the middle of the support plate 6, a lifting cylinder 23 is installed in the mounting groove 22, and an air supply channel 24 is horizontally penetrated on the support block plate, one side of the air supply channel 24 is connected to the lifting cylinder 23, and adjacent air supply channels 24 are connected through an air supply pipe 25.

[0056] When in use, according to the actual number of U-bolts 5 used, an appropriate amount of fastening structure is selected, and the lifting cylinders 23 between the adjacent support plates 6 are connected through the air supply pipe 25 and the air supply channel 24. After the U-bolt 5 is threadedly connected with the nut 10, and the pin rod 16 fixes the U-bolt 5 through the pin hole 18 of the tapered rod 17, a group of air supply channels 24 are used to connect the air source. After the air source enters the lifting structure through the air supply channel 24, the air source is transported to several adjacent groups of lifting cylinders 23 by the air supply pipe 25, so as to drive several groups of lifting cylinders 23 to lift. When the lifting cylinders 23 are lifted, the main body 1 is squeezed close to the pressure plate 2, thereby improving the tightness between the main body 1 and the pressure plate 2. When the lifting cylinder 23 lifts the main body 1 to a certain position, the staff needs to use a wrench to rotate the nut 10, so as to further improve the tightness between the nut 10 and the U-bolt 5, and prevent the pressure plate 2 and the main body 1 from loosening in the later stage.

[0057] It should be pointed out that before connecting the air source, one end of the air supply channel 24 away from the air source should be blocked by a blocking device to avoid air leakage when supplying air to all the lifting cylinders 23 at the same time; and it should be pointed out that the blocking device can be a valve or a plug bolt or other parts that are easy to disassemble.

[0058] When the present invention is in use, the power transmission line is placed between the main body 1 and the pressure plate 2, and the lower end of the U-bolt 5 is passed through the mounting hole 4 of the main body 1, so that the pressure plate 2 is abutted against the main body 1, and the nut 10 is placed in the hexagonal groove 9. When the U-bolt 5 needs to be tightened, the U-bolt 5 is pressed downward, and the U-bolt 5 corresponds to the nut 10 in the hexagonal groove 9 when it moves downward. At the same time, the sliding seat 8 is driven downward by the downward extrusion of the U-bolt 5. After the sliding seat 8 moves down to a certain position, the clamping block 20 is disengaged from the clamping groove 21. At this time, the sliding seat 8 is driven to rotate by the reset effect of the torsion spring 12. When the sliding seat 8 rotates, the nut 10 is driven to rotate by the hexagonal groove 9. When the nut 10 rotates, it is threadedly connected with the lower end of the U-bolt 5, so that the nut 10 is threadedly connected with the U-bolt 5, thereby improving its installation efficiency;

[0059] As the U-bolt 5 continues to move downward, the tapered rod 17 at the lower end of the U-bolt 5 passes through the sliding hole 19 of the sliding seat 8 and is slidably connected to the sliding hole 19. When the tapered rod 17 moves downward to a certain position, the tapered rod 17 is pressed and contacted with the pin rod 16, and drives the pin rod 16 to move. When the pin rod 16 moves, it drives the reset spring 14 to store force, and at the same time drives the extrusion plate 13 and the support plate 6 away. When the tapered rod 17 moves downward to a certain position, the reset effect of the reset spring 14 drives the pin rod 16 to reset and move. When the pin rod 16 resets and moves, the end of the pin rod 16 away from the extrusion plate 13 passes through the pin hole 18 of the tapered rod 17 and is slidably connected to the pin hole 18, so as to fix the U-bolt 5;

[0060] At the same time, a group of air supply channels 24 are used to connect the air source. After the air source enters the jacking structure through the air supply channel 24, the air supply pipe 25 is used to transport the air source to several adjacent groups of jacking cylinders 23, so as to drive several groups of jacking cylinders 23 to lift. When the jacking cylinders 23 are lifted, the main body 1 and the pressure plate 2 are squeezed close to each other, thereby improving the tightness between the main body 1 and the pressure plate 2. When the jacking cylinders 23 lift the main body 1 to a certain position, the staff needs to use a wrench to rotate the nut 10, so as to further improve the tightness between the nut 10 and the U-bolt 5, and prevent the pressure plate 2 and the main body 1 from loosening in the later stage.

[0061] When the U-bolt 5 and the nut 10 are tightened, the extrusion plate 13 and the support plate 6 are manually moved away from each other to disengage the pin rod 16 from the pin hole 18 of the tapered rod 17. At this time, the support plate 6 can be taken out to disengage the U-bolt 5 from the support plate 6. At the same time, the sliding seat 8 is rotated again to store force, and a new nut 10 is placed in the hexagonal groove 9, so as to facilitate the subsequent quick installation of the next set of U-bolts 5.

[0062] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
