The cylindrical body is manufactured through welding. During tower welding, an electrical connection needs to be established between the cylindrical body and one output terminal of the welding machine's power supply to stably return the welding current to the power source, forming a low-impedance loop.

[0040] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0042] In the industrial manufacturing sector, the cylindrical body is the core structural unit constituting a cylindrical tower, pressure vessel, or piping system. Cylindrical towers can be used in power systems or railway systems. In power systems, they can be used to install wind turbines or cables; in railway systems, they can be used to install signaling equipment or to lay communication or power cables.

[0043] The cylinder body is manufactured through welding. During the tower welding process, an electrical connection needs to be made between the cylinder body and one output terminal of the welding machine's power supply to stably return the welding current to the power supply, forming a low-impedance loop. This process is known as welding grounding in the welding field. During cylinder welding, roller frames can be used to support, lift, and rotate the cylinder body.

[0044] For example, a roller frame is mounted on a rail to guide its movement. The cylinder is placed on the roller frame, and the rotation of the rollers on the roller frame drives the cylinder to rotate in the circumferential direction for welding displacement. The movement of the cylinder within the work area is driven by the movement of the roller frame relative to the rail.

[0045] In the prior art, the cylinder is grounded by placing a grounding iron on the cylinder to form a conductive contact between the grounding iron and the cylinder.

[0046] However, due to the curved surface structure of the cylinder, it is difficult to place the grounding iron stably on the cylinder surface, which can easily cause unstable grounding during welding.

[0047] It should be noted that in some existing technologies, a stable grounding is achieved by welding connecting columns or bolts to the surface of the cylinder and then fastening the grounding to the surface of the cylinder with fasteners. However, this technology requires repair treatment of the cylinder surface after welding (cutting the corresponding connecting columns or bolts and grinding). However, this treatment method affects the quality of the cylinder and adds new work content, which affects the work efficiency.

[0048] To address the problem of unstable grounding during cylinder welding in existing technologies, this application provides a welding grounding device. This device is supported on the ground by a base and uses a lifting mechanism to raise and lower a welding auxiliary device. The rising of the welding auxiliary device allows two conductive components on a first support to be supported on the cylinder, making conductive contact with the cylinder for welding grounding. Thus, the support of the welding auxiliary device by the base and the lifting mechanism facilitates stable contact between the conductive components and the cylinder, solving the problem of unstable grounding during cylinder welding in existing technologies. The welding auxiliary device, through the first and second supports, forms a cross-shaped support with the cylinder, improving the stability of the welding auxiliary device supported on the cylinder and helping to maintain stable welding grounding. Furthermore, the lowering of the welding auxiliary device by the lifting mechanism facilitates disengagement of the conductive components from the cylinder, allowing for quick and easy termination of the welding grounding after welding without leaving any residual connection points on the cylinder surface.

[0049] Reference Figures 1 to 9 As shown, the welding grounding device provided in this application embodiment is used for welding cylinder 10. The welding grounding device includes: base 100, lifting component 200 and welding auxiliary device 300.

[0050] The base 100 is adapted to be supported on the ground. For example, the base 100 may be made of metal such as steel, or it may be made of non-metallic material. The shape of the base may be disc-shaped, cylindrical, radial (e.g., cross-shaped), or cuboid. Of course, this application does not limit this and can be flexibly set according to needs.

[0051] The lifting element 200 is movably mounted on the base 100. For example, the lifting element 200 can be a type based on a threaded lifting principle, such as a screw that moves up and down by rotating relative to its mating internal thread; the lifting element 200 can be a type based on a pneumatic or hydraulic drive principle, such as a lifting rod of a pneumatic or hydraulic cylinder; or the lifting element 200 can be a type based on an electric drive principle, such as a lifting rod of an electric cylinder. It is understood that the connection method between the lifting element 200 and the base 100 can be determined specifically according to the specific type of the lifting element 200.

[0052] The welding auxiliary device 300 is connected to the lifting member 200 to move up and down with the lifting member 200. For example, the welding auxiliary device 300 and the lifting member 200 may be fixedly connected; or, the welding auxiliary device 300 and the lifting member 200 may be movably connected. The welding auxiliary device 300 includes a first support 310 and a second support 320.

[0053] The first support 310 extends circumferentially along the cylinder 10, such that both ends of the first support 310 are positioned as close as possible to the cylinder 10. For example, the first support 310 can be an arc-shaped plate; or, the cylinder 10 can be approximately "V" shaped, where the included angle between the two sides of the "V" shape can be an obtuse angle.

[0054] One end of the first support 310 is provided with a conductive element 311, and the other end of the first support 310 is provided with another conductive element 311. The conductive element 311 is adapted to support the cylinder 10 and make conductive contact with the cylinder 10. For example, the upper surface of the conductive element 311 can be an arc surface, the radius of which is approximately equal to the radius of the outer surface of the cylinder, so as to ensure the contact area with the cylinder 10 through the arc surface. For example, the material of the conductive element can be graphene, a composite material with a graphene surface, steel or copper alloy, etc., but this application does not limit it.

[0055] The second support 320 extends along the axial direction of the cylinder 10. Support components 321 are provided at both ends of the second support 320, and the support components 321 are used to support the cylinder 10.

[0056] For example, when using this application, each conductive element 311 can be connected to the corresponding power line of the welding machine for welding grounding.

[0057] Specifically, the power cord can be directly connected to one of the conductive components 311 (for example, the power cord includes a metal connector that can be soldered to the conductive component 311, and the connection is made by soldering; or the power cord includes a conductive nose that can be tightened by bolts, and the conductive nose is fastened to the conductive component 311 by bolts). The conductive components 311 are electrically connected to each other by wires so that each conductive component 311 is electrically connected to the power cord.

[0058] Alternatively, when the first bracket 310 is a conductor, each conductive element 311 can make conductive contact with the first bracket 310, so that the conductive elements 311 can be electrically connected to each other through the first bracket 310; in this case, a power cord can be connected to the first bracket 310. Furthermore, a wiring component for connecting the power cord, such as a bolt, can be provided on the first bracket 310.

[0059] Alternatively, when both the first bracket 310 and the second bracket 320 are conductors, each conductive element 311 can make conductive contact with the first bracket 310 so that each conductive element 311 can be electrically connected to each other through the first bracket 310; the second bracket 320 can make conductive contact with the first bracket 310; in this case, the power cord can be connected to the second bracket 320.

[0060] Alternatively, in some possible embodiments, if there is a conductive connection between the base 100 and the conductive element 311, the power cord can be connected to the base. If there is a conductive connection between the lifting element 200 and the conductive element 311, the power cord can be connected to the lifting element 200. It is understood that in some possible embodiments, the power cord may be connected to any location in the welding grounding device provided in this application that is electrically connected to the conductive element 311.

[0061] The welding grounding device provided in this embodiment is supported on the ground by a base 100. A lifting member 200 drives the welding auxiliary device 300 to rise and fall. The rising of the welding auxiliary device 300 causes two conductive elements 311 on the first support 310 to be supported on the cylinder 10, making conductive contact with the cylinder 10 for welding grounding. Thus, the support of the welding auxiliary device 300 by the base 100 and the lifting member 200 facilitates stable contact between the conductive elements 311 and the cylinder 10, solving the problem of unstable welding grounding of the cylinder 10 in the prior art. The welding auxiliary device 300, through the first support 310 and the second support 320, can form a cross-shaped support with the cylinder 10, improving the stability of the welding auxiliary device 300 supported on the cylinder 10 and helping to maintain the stability of the welding grounding. In addition, the lifting component 200 drives the welding auxiliary device 300 to descend, which facilitates the disconnection between the conductive component 311 and the cylinder 10. This allows for quick and easy removal of the welding grounding of the cylinder after welding is completed, without causing any residual connection points on the surface of the cylinder 10.

[0062] It should be noted that the welding grounding device of this application can be used in conjunction with the roller frame in the prior art to support and lift the cylinder 10, so as to bear most of the weight of the cylinder 10.

[0063] Reference Figure 1 , Figure 2 , Figure 5 and Figure 9 As shown, in some embodiments, the support assembly 321 includes a support member 321a and rollers 321b. The support member 321a includes a frame 321a1 and rollers 321a2. The frame 321a1 extends circumferentially along the cylinder 10, and rollers 321a2 are respectively provided at both ends of the frame 321a1 along the circumferential direction of the cylinder 10. The axis of the rollers 321a2 is parallel to the axis of the cylinder 10. Two rollers 321b are corresponding to the rollers 321a2, and the rollers 321b are rotatably mounted on their respective rollers 321a2. The cylinder 10 is adapted to support the rollers 321b.

[0064] Thus, the support assembly 321 supports the cylinder 10 via the roller 321b. The rolling motion of the roller 321b reduces friction on the cylinder 10, protecting its surface and preventing severe scratches when the support assembly 321 contacts the cylinder 10. Furthermore, the frame 321a1 increases the circumferential support span of the support assembly 321 on the cylinder 10, ensuring effective support.

[0065] Reference Figure 1 , Figure 5 and Figure 9 As shown, the frame 321a1 is further described as an elastic element. For example, along the circumference of the cylinder 10, the two ends of the frame 321a1 are higher than the middle. When the two ends of the frame 321a1 are subjected to downward pressure, the frame 321a1 can undergo elastic deformation to generate elastic force. Thus, under the pressing action of the weight of the cylinder 10, the frame 321a1 undergoes elastic deformation, allowing it to conform to the outer contour of the cylinder 10, facilitating its adaptability to cylinders of different diameters.

[0066] Furthermore, the roller 321b can be configured to contact the outer surface of the cylinder 10 before the conductive element 311 during the upward movement of the lifting frame 200. For example, the first support 310 and the second support 320 can also be elastic elements.

[0067] Reference Figure 1 , Figure 2 and Figure 9 As shown, in some embodiments, the middle portions of the first support 310 and the second support 320 intersect and connect. Exemplarily, this connection can be welding, or it can be secured by fasteners. Thus, the first support 310 and the second support 320 form a single unit, facilitating mutual support and improving the stability of the conductive element 311 and the support assembly 321 on the surface of the cylinder 10.

[0068] Reference Figure 1 , Figure 2 and Figure 4As shown, in some embodiments, a connecting seat 322 is provided in the middle of the second bracket 320, and the first bracket 310 passes through the connecting seat 322. The connecting seat 322 is also connected to the lifting member 200 to move up and down under the drive of the lifting member 200. For example, the connecting seat 322 has a channel for the first bracket 310 to pass through. This prevents the first bracket 310 from rotating relative to the second bracket 320, thus enhancing the stability of the connection position between the first bracket 310 and the second bracket 320. For example, the first bracket 310 can be fastened to the aforementioned channel on the connecting seat 322 with bolts. It is understood that when the first bracket 310 is fastened to the connecting seat 322 with bolts, it is convenient to disassemble and replace the first bracket 310. Alternatively, the first bracket 310 can be welded to the aforementioned channel on the connecting seat 322. By providing the connecting seat 322, it is convenient to connect the welding auxiliary device 300 and the lifting member 200.

[0069] Reference Figure 1 , Figure 4 and Figure 9 As shown, in some embodiments, the connecting seat 322 is also provided with a pivot hole 322a. The top of the lifting member 200 is provided with a pivot shaft 210, which passes through the pivot hole 322a, so that the connecting seat 322 can rotate relative to the lifting member 200. In this way, on the one hand, the welding auxiliary device 300 as a whole can rotate relative to the lifting member 200, and before the conductive member 311 and the support assembly 321 are supported on the cylinder 10, the orientation of the welding auxiliary device 300 can be easily adjusted by rotation to adjust the conductive member 311 and the support assembly 321 to a more suitable position relative to the cylinder 10, so as to ensure the contact state of the conductive member 311 and the surface of the cylinder 10 after docking.

[0070] Reference Figure 1 , Figure 4 and Figure 9 As shown, on the other hand, in the case where at least one of the frame 321a1 and the second support 320 is an elastic element, and the roller 321b is configured to contact the outer surface of the cylinder 10 before the conductive element 311 during the lifting process of the lifting frame 200, the roller 321b will drive the second support 320 and the first support 310 to rotate relative to the pivot axis 210 during the process from the beginning of contact with the surface of the cylinder 10 to the point of contact (the roller 321b and the cylinder 10 are parallel in axis), so as to drive the conductive element 311 to adjust its orientation so that the radial direction of the arc surface of the conductive element 311 is parallel to the radial direction of the cylinder 10; in summary, this facilitates the automatic alignment of the conductive element 311.

[0071] Reference Figure 4As shown, in some embodiments, the welding grounding device further includes a bearing member 400. The bearing member 400 is disposed within the pivot hole 322a, and the outer ring of the bearing member 400 is fixedly fitted to the connecting seat 322. Exemplarily, this fixed fit can be an interference fit or welding. The inner ring of the bearing member 400 is sleeved on the pivot shaft 210. Exemplarily, the pivot shaft 210 and the inner ring of the bearing member 400 can be welded together. Thus, the bearing member 400 facilitates improved smoothness of the rotational movement of the welding auxiliary device 300 relative to the lifting member 200, and is particularly beneficial for the automatic alignment of the aforementioned conductive member 311.

[0072] Reference Figure 1 , Figure 3 , Figure 4 and Figure 9 As shown, in some embodiments, the first bracket 310 is further provided with fixing frames 312 at both ends, the fixing frames 312 enclosing an installation space 312d, and at least a portion of the conductive element 311 is detachably disposed within the installation space 312d. This allows the conductive element 311 to be replaced. For example, the upper surface of the conductive element 311 is an arc surface that matches the surface of the cylinder 10. When the diameter of the cylinder 10 to be processed changes, the conductive element 311 is replaced to accommodate the change in the diameter of the cylinder 10. For example, the conductive element 311 can be pluggably disposed within the installation space 312d for replacement by a plugging and unplugging action, with the unplugging direction generally facing upwards and the plugging direction generally facing downwards.

[0073] The peripheral wall of the fixing frame 312 is provided with a locking device 313, which is used to adjust the tightness of the conductive element 311. This allows a gap to exist between the mounting space 312d and the portion into which the conductive element 311 is inserted, reducing the difficulty of installing or removing the conductive element 311 from the mounting space 312d. The locking device 313 facilitates locking the conductive element 311. Exemplarily, in some possible embodiments, the locking device 313 may be a pin.

[0074] For example, when it is necessary to replace the conductive component 311, first release the locking device 313 from locking the conductive component 311 in the fixed frame 312, then pull the conductive component 311 that needs to be removed out of the fixed frame 312; then insert the new conductive component 311 into the fixed frame 312 and lock it with the locking device 313.

[0075] Reference Figure 3 and Figure 4As shown, in some embodiments, the fixing frame 312 includes two first sidewalls 312a opposite each other along a first direction and two second sidewalls 312b opposite each other along a second direction. One of the first sidewalls 312a and one of the second sidewalls 312b are each provided with a through hole 312c. The locking device 313 includes two locking bolts 313a, which are respectively inserted into the two through holes 312c, and the locking bolts 313a are threaded into the through holes 312c. Thus, the conductive element 311 is locked in the mounting space 312d by the two locking bolts 313a, which helps to provide sufficient locking force and ensures the stability of the conductive element 311 on the fixing frame 312.

[0076] For example, under the action of one of the locking bolts 313a, one side of the conductive element 311 is pressed against the inner wall of the mounting space 312d, and the side of the conductive element 311 and the inner wall of the mounting space 312d are in surface conductive contact (e.g., planar conductive contact) to ensure the conductivity between the conductive element 311 and the fixing frame 312; under the action of the other locking bolt 313a, another side of the conductive element 311 is pressed against the inner wall of the mounting space 312d, and the side of the conductive element 311 and the inner wall of the mounting space 312d are in surface conductive contact (e.g., planar conductive contact) to ensure the conductivity between the conductive element 311 and the fixing frame 312.

[0077] Reference Figure 1 , Figure 4 and Figure 9 As shown, in some embodiments, the base 100 includes a base body 110 and a mounting cylinder 120. The base body 110 is adapted to be supported on the ground; for example, the base body 110 may be plate-shaped, such as a circular plate, a rectangular plate, etc.; or the base body 110 may be frame-shaped; or the base body 110 may be radial (e.g., cross-shaped, etc.).

[0078] The mounting cylinder 120 has a vertically extending inner cavity 121, and the lifting member 200 is movably disposed within the inner cavity 121 of the mounting cylinder 120. Exemplarily, in some possible embodiments, the lifting member 200 may have a plurality of first pin holes spaced apart along its height direction, and the mounting cylinder 120 may have second pin holes for alignment with the first pin holes. The height of the lifting member 200 is locked by inserting a pin between the second pin hole and the corresponding first pin hole; it is understood that if the height of the lifting member 200 needs to be adjusted, the pin can be pulled out.

[0079] Reference Figure 1 , Figure 4 and Figure 9As shown, or in some embodiments, both the inner wall of the mounting cylinder 120 and the side wall of the lifting member 200 are threaded, and the lifting member 200 and the mounting cylinder 120 are threadedly engaged. Thus, the lifting member 200 can be raised or lowered by rotating it relative to the mounting cylinder 120, and the self-locking of the threaded engagement can maintain the lifting member 200 at a corresponding height; furthermore, the threaded engagement facilitates stepless adjustment of the height of the lifting member 200, making it easy to precisely adjust the contact degree between the conductive member 311 and the outer surface of the cylinder 10.

[0080] For example, when the lifting component 200 and the mounting cylinder 120 are threaded together, a nut can be welded to the lifting component 200 to facilitate turning the nut with a wrench, thereby increasing the torque of rotating the lifting component 200. Alternatively, a handle perpendicular to the lifting component 200 can be welded to the lifting component 200 to rotate the lifting component 200, reducing the difficulty of rotating the lifting component 200.

[0081] Reference Figure 1 As shown, in some embodiments, the seat body 110 includes a plurality of beams 111, which are arranged intersectingly. The mounting cylinder 120 is connected to the intersecting areas of the beams 111, i.e., the seat body 110 is radially arranged as described above. This arrangement facilitates increasing the contact area between the seat body 110 and the ground, and the spacing between the beams 111 helps to avoid uneven areas on the ground. For example, the beams 111 can be structural steel, such as channel steel or I-beams; or they can be steel pipes, such as round or square pipes. For example, the beams 111 can be connected by welding at the intersecting areas, or detachably connected by bolts using appropriate connectors. When the seat body 110 includes a plurality of intersecting beams 111, the bottom of the mounting cylinder 120 can be fixed to the top of the seat body 110 by welding.

[0082] Reference Figure 1 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments, the welding grounding device further includes a stabilizing auxiliary device 500. The stabilizing auxiliary device 500 includes a moving clamp 510 and a pressure applying device 520.

[0083] A movable clamp 510 is movably mounted on the track 20. For example, the track 20 may be for mounting a roller frame. The movable clamp 510 can be held in place on the track 20; when adjustment of the movable clamp 510 relative to the track 20 is required, the clamping of the movable clamp 510 on the track 20 can be released. A pressure device 520 is located on one side of the track 20 and is connected to the movable clamp 510 via a first movable rod 530. The pressure device 520 is adapted to apply a fixed force toward the ground to the base 100.

[0084] Thus, the stabilizing auxiliary device 500 can apply a fixed force towards the ground to the base 100 via the track 20, which helps to stabilize the base 100 on the ground, especially on some unhardened surfaces. It should be noted that this application does not impose a specific limit on the number of stabilizing auxiliary devices 500, and they can be flexibly set according to needs.

[0085] For example, when welding the cylinder 10, the base 100 can be placed on the ground between two parallel tracks 20. Stabilizing auxiliary devices 500 can be connected to both tracks 20 to apply a fixed force toward the ground to the part of the base 100 adjacent to the corresponding stabilizing auxiliary device 500, so as to stabilize the base.

[0086] Reference Figure 1 , Figure 6 , Figure 7 and Figure 8As shown, in some embodiments, the movable clamp 510 includes a first clamp 511 and a second clamp 512. The first clamp 511 is located on one side of opposite sides of the track along its width direction, and the second clamp 512 is located on the other side of opposite sides of the track along its width direction. The first clamp 511 and the second clamp 512 together clamp the track. Exemplarily, the first clamp 511 and the second clamp 512 can be sourced from the clamping force provided by a fastener, for example, a first bolt 514. There are two first bolts 514, which are parallel to each other. The first clamp 511 has a hole for the first bolt 514 to pass through. This hole can be a smooth hole (i.e., a smooth inner wall without threads). The first bolt 514 passes through the first clamp 511. The second clamp 512 has a threaded hole for engaging with the first bolt 514. The first bolt 514 is threadedly connected to the second clamp 512. Alternatively, in some possible embodiments, the first chuck 511 and the second chuck 512 can be connected by a spring or other elastic element, so that the elastic force provided by the elastic element serves as the source of the clamping force. The second chuck 512 is provided with a mounting portion 513, which has a lead screw hole 513a extending through the width direction of the track. The first movable rod 530 is a lead screw, which passes through the lead screw hole 513a; a pressure applying device 520 is provided at one end of the first movable rod 530. For example, the lead screw hole 513a is an internal thread that mates with the first movable rod 530.

[0087] Thus, the first clamp 511 and the second clamp 512 jointly clamp the track 20. When it is necessary to adjust the position of the moving clamp 510 on the track, the first clamp 511 and the second clamp 512 can be disengaged to release the clamp. When the moving clamp 510 is clamped on the track 20, the pressure applying device 520 can be moved by rotating the first movable rod 530, so that the pressure applying device 520 is moved above or away from the base 100. It can be understood that when the pressure applying device 520 is moved above the base 100, it can apply a downward pressing action to the base. By adjusting the position of the pressure applying device 520 through the first movable rod 530, the stabilizing auxiliary device 500 provided in this embodiment can be applied to tracks 20 with different spacing.

[0088] It should be noted that during the welding operation, the axis of the cylinder 10 is approximately located in the middle between the two tracks 20. Therefore, the welding grounding device provided in this application needs to be placed approximately in the middle between the two tracks. When the distance between the two tracks 20 changes, the distance between the base 100 and the tracks 20 also changes accordingly. The adjustment of the position of the pressure device 520 by the first movable rod 530 in the above embodiment can cope with this change.

[0089] Reference Figure 1 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the pressure applying device 520 includes a mounting member 521, a second movable rod 522, and a force applying member 523. The mounting member 521 is connected to the first movable rod 530; for example, the mounting member 521 has a first connecting portion 521a, and the first movable rod 530 is rotatably connected to the first connecting portion 521a. The first connecting portion 521a limits the first movable rod 530 along the axial direction of the first movable rod 530, so that when the first movable rod 530 moves, it drives the first connecting portion 521a to move, thereby driving the mounting member 521 to move.

[0090] Two guide rods 540 are fixed on the mounting component 521, and both guide rods 540 are parallel to the first movable rod 530. The guide rods 540 pass through the mounting part 513 and can move relative to the mounting part 513. The guide rods 540 are used to guide the movement of the mounting component 521.

[0091] The second movable rod 522 is movably inserted through the mounting member 521 in a vertical direction; the force-applying member 523 is located at the bottom end of the mounting member 521 and is used to apply pressure to the base 100. For example, the force-applying member 523 can be configured as a counterweight to apply pressure to the base 100 by gravity. Alternatively, the second movable rod 522 is threadedly connected to the mounting member 521. When the second movable rod 522 rotates relative to the mounting member 521, the second movable rod 522 rises or falls. When the second movable rod 522 falls, it can press down on the force-applying member 523, causing the force-applying member 523 to press against the base 100.

[0092] For example, when the seat body 110 includes a plurality of intersecting beams 111, the bottom of the force-applying member 523 may have a locking opening, which is used to lock onto the top surface of the beam 111 and limit the two opposite facades of the beam, so as to form a stable limit on the beam 111 when pressing the beam 111.

[0093] When it is necessary to apply pressure to the base 100 through the force-applying component 523, the mounting component 521 must first be moved above the base 100 by the first movable rod 530; then the force-applying component 523 is adjusted to descend by the second movable rod 522 to press down on the base 100.

This utility model is intended to cover any variations, uses, or adaptations of this utility model that follow the general principles of this utility model and include common knowledge or customary techniques in the art not disclosed herein, and is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope.
