Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a welding device for non-metallic materials. Background Technology

[0002] With the continuous development of national defense scientific research, radiomedicine and nuclear technology applications, various types of radioactive rays are widely used. The harm of rays to the human body and the damage to the environment are gradually being recognized by mankind. Polyethylene is the most widely used because it has the highest hydrogen content.

[0003] Typically, polyethylene shielding materials are molded using methods such as compression molding, extrusion molding, and injection molding. Compression molding is usually chosen for manufacturing large-sized, thick products. Currently, in the structural design of shielding materials, the protected area has a complex structure and requires a large shielding layer. Furthermore, to ensure shielding effectiveness, the number of blocks and splicing of shielding materials is reduced when designing the protective structure. This necessitates that shielding material products be large-scale and integrated, which traditional molding methods can hardly meet. Therefore, it is necessary to consider connecting shielding material products, thereby increasing the overall size of the product.

[0004] Generally speaking, the connection methods between materials can be divided into physical connection and chemical connection. Physical connection has disadvantages such as easy loosening, poor sealing, and stress concentration due to material openings, which can easily lead to breakage. It is difficult to meet the requirements of high efficiency and high reliability for connecting plastic assemblies. Fusion welding, on the other hand, does not require the addition of adhesives or fluxes, and there is no electric arc or smoke generated, making it a green, energy-saving, and environmentally friendly welding method. Most existing welding equipment focuses on welding metallic materials, and it is difficult to fully meet the special requirements of welding non-metallic materials. For example, welding non-metallic materials requires high precision in positioning of the welded parts, uniform heating, and stable control of welding pressure. Traditional welding equipment is significantly inadequate in these aspects, making it difficult to effectively guarantee the quality and efficiency of non-metallic material welding.

[0005] Meanwhile, the literature on polyethylene hot melt welding technology mainly focuses on polyethylene pipe welding, with little research on polyethylene sheet welding technology, especially the welding of thick sheet products. Therefore, this invention designs a welding device based on the welding requirements of thick shielding materials, providing a hardware foundation for realizing the feasibility of the welding process.

[0006] Therefore, this utility model provides a non-metallic material welding device to solve the above-mentioned problems in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] According to a first aspect of the present invention, a non-metallic material welding equipment includes a welding table, a first welding sliding assembly, a second welding sliding assembly, a lifting device, a heating plate, a first driving device, and a second driving device.

[0009] The welding table frame is provided with a first welding sliding assembly and a second welding sliding assembly spaced apart along its length.

[0015] Furthermore, the first welding sliding assembly and the second welding sliding assembly have the same structure and are arranged in a mirror image.

Multiple guide rails are arranged horizontally along the length of the welding table frame. Multiple universal balls are evenly provided at the bottom of the sliding platform. The universal balls slide and abut against the guide rail.

[0016] Furthermore, it also includes a reinforcing angle, wherein the reinforcing angle is provided at the edge of the end of the sliding platform away from the strip opening, the bottom of the reinforcing angle is fixedly connected to the bottom of the sliding platform, and the side plate of the reinforcing angle is fixedly connected to the side plate of the sliding platform.

[0017] Furthermore, the first driving device and the second driving device have the same structure and are arranged in a mirror image. Both the first driving device and the second driving device include a hydraulic cylinder, a hydraulic baffle and a flange. The hydraulic baffle is fixedly arranged at the end of the welding table away from the strip opening, and the hydraulic baffle and the strip opening are arranged parallel to each other. The hydraulic cylinder is vertically arranged on the hydraulic baffle. The output end of the hydraulic cylinder is provided with a flange. The flange of the hydraulic cylinder of the first driving device abuts against the first welding sliding assembly, and the flange of the hydraulic cylinder of the second driving device abuts against the second welding sliding assembly.

[0018] Furthermore, it also includes a fixing device, which is disposed on the first welding sliding assembly or the second welding sliding assembly along the width direction of the welding table frame, and the fixing device is used to fix the parts carried on the first welding sliding assembly or the second welding sliding assembly.

[0019] Furthermore, the fixing device includes two side-pressure brackets, a pneumatic cylinder, and a hand-cranked screw. The two side-pressure brackets are arranged opposite each other at both ends of the first welding sliding assembly or the second welding sliding assembly. The outer wall of the part abuts against the inner wall of the side-pressure bracket. The hand-cranked screw is provided at the top of one of the side-pressure brackets, and the output end of the hand-cranked screw presses against one side of the top surface of the part. The pneumatic cylinder is provided at the top of the other side-pressure bracket, and the output end of the pneumatic cylinder presses against the other side of the top surface of the part. The pneumatic cylinder and the hand-cranked screw are both arranged along the height direction of the welding table.

[0020] Furthermore, the bottom of the welding table frame is provided with a first foot and a first universal wheel.

[0022] Furthermore, a fixed pulley is provided in the middle of the crossbeam, a winding reel is provided on the output shaft of the motor, one end of the flexible chain is wound on the winding reel, and the other end of the flexible chain is fixed on the fixed pulley.

[0023] This utility model has the following advantages:

[0024] (1) The first and second welding sliding components are spaced apart along the length of the welding table, providing a stable and precise mounting base for welding part one and welding part two. By fixing the welding parts to their respective sliding components, combined with the strip-shaped opening design of the welding table, the relative positions of the welding parts can be accurately determined in the horizontal direction (the length direction of the welding table). This is particularly crucial in non-metallic material welding where high precision of the weld joint position is required. For example, in the welding of plastic shells for some precision electronic devices or the splicing of small composite material parts, precise positioning can effectively reduce welding deviations and improve the quality and pass rate of the welded products.

[0025] (2) The first and second driving devices are located at opposite ends of the welding table, respectively, and can precisely control the opposing movement of the first and second welding sliding components. This allows welding part one and welding part two to quickly and stably fit together, reducing welding preparation time and improving the overall efficiency of the welding operation. In the mass production of non-metallic welded products, an efficient welding process can significantly increase production capacity and reduce production costs.

[0026] (3) The combination of the lifting device and the heating plate enables flexible lifting and lowering of the heating plate along the height of the welding table. During the welding process, the distance between the heating plate and the welding parts can be precisely adjusted according to the characteristics of different non-metallic materials, the thickness of the welding parts, and the welding process requirements. For thinner non-metallic materials, the height of the heating plate can be appropriately reduced to avoid overheating; while for thicker materials or materials with poor thermal conductivity, the heating plate can be raised to ensure that the welding area is fully heated. This adjustability ensures the uniformity and precision of heating, which is conducive to obtaining high-quality welding results, such as higher strength and better sealing of the weld joint.

[0027] (4) Because the height of the heating plate can be flexibly controlled, the equipment can adapt to various non-metallic material welding processes. For example, in the welding of thermoplastic plastics, the temperature and height of the heating plate can be precisely adjusted according to the melting point and softening temperature range of the plastic to achieve precise control of the welding process; for some special non-metallic material welding processes that require preheating or post-heat treatment, the position of the heating plate and the heating time can also be easily adjusted through the lifting device to meet different process requirements and broaden the application range of the equipment.

[0028] (5) The heating plate moves up and down inside the welding table frame through strip-shaped openings, making full use of the internal space of the welding table frame and avoiding the heating plate occupying a large amount of extra space on the outside, making the equipment look simpler and more beautiful. In addition, the reasonable layout of each component on the welding table frame also provides operators with a more spacious and convenient operating space, which is conducive to improving the comfort and safety of operation, reducing the misoperation caused by narrow operating space, and further improving the quality and efficiency of welding operations.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0051] Example 1

[0052] like Figures 1 to 13 As shown, a non-metallic material welding device according to the first aspect of the present invention includes a welding table frame 3, a first welding sliding assembly, a second welding sliding assembly, a lifting device, a heating plate 31, a first driving device, and a second driving device.

[0053] The welding table frame 3 is a segmented structure, composed of two small tables of the same size. The two small tables are spaced apart and arranged in a straight line. The ends of the two small tables are detachably connected by a tabletop fixing plate 4 and a small table connecting plate 5. The tabletop fixing plate 4 is located above the small table connecting plate 5. The tabletop fixing plate 4 is usually L-shaped. The tabletop 6 of one small table and the tabletop 7 of the other small table are detachably connected by the tabletop fixing plate 4. The legs of the small tables are detachably connected by the small table connecting plate 5.

[0054] The welding table frame 3 is provided with a first welding sliding assembly and a second welding sliding assembly at intervals along its length. A strip-shaped opening 301 is provided at the interval between the first welding sliding assembly and the second welding sliding assembly. The strip-shaped opening 301 is opened along the width direction of the welding table frame 3. Welding part one 104 is fixed on the first welding sliding assembly, and welding part two 105 is fixed on the second welding sliding assembly.

[0055] The lifting device is installed inside the welding table frame 3. The bottom of the lifting device is fixed inside the welding table frame 3 through the lifting platform connecting plate 12. The top of the lifting device is provided with a heating plate 31. The heating plate 31 has a strip-shaped opening 301. The lifting device drives the heating plate 31 to move up and down along the height direction of the welding table frame 3. This lifting device can be an existing lifting device, such as a pneumatic or hydraulic lift.

[0056] The welding table 3 is provided with a first driving device near the end of the first welding sliding assembly. The first driving device is used to drive the first welding sliding assembly. The welding table 3 is provided with a second driving device near the end of the second welding sliding assembly. The second driving device is used to drive the second welding sliding assembly. During welding, the first driving device and the second driving device move towards each other to make the welding part 104 and the welding part 205 fit together and abut.

[0057] Usage and working principle:

[0058] I. How to use

[0059] Equipment assembly and preparation

[0060] Assemble the welded table frame, which is made up of two identical small tables. Arrange the two small tables in a straight line with a gap between them, and then connect them using a tabletop fixing plate and a small table connecting plate. Detachably connect the top two ends of the L-shaped tabletop fixing plate to the ends of the two small tables with screws. Install the straight small table connecting plate, which is approximately the same height as the table legs, at the end of the gap between the two small tables, below the tabletop fixing plate, to ensure the welded table frame structure is stable.

[0061] Install the first and second welding sliding assemblies along the length of the welding table, and check that the strip opening is correctly made and unobstructed. Fix welding part one to the first welding sliding assembly, and welding part two to the second welding sliding assembly. Use appropriate clamps or fixing devices to ensure that the parts are firmly installed and accurately positioned.

[0062] If the lifting device uses a pneumatic or hydraulic lift, check whether its connecting pipes, valves, and other components are normal to ensure that the lifting device can operate normally. Install the heating plate on the top of the lifting device, ensuring that the heating plate can easily pass through the strip opening.

[0063] Install a first drive device at the end of the welding table near the first welding sliding assembly, and install a second drive device at the end near the second welding sliding assembly. Check whether the connection and power source of the drive device are normal, and adjust the drive device to make it work properly.

[0064] Welding operation procedure

[0065] Turn on the heating plate and set the heating temperature and time according to the welding process requirements. Adjust the height of the heating plate using the lifting device. Activate the first and second drive devices, causing them to move towards each other. The first drive device pushes the first welding sliding assembly carrying welding part one, and the second drive device pushes the second welding sliding assembly carrying welding part two. As they gradually approach each other, the heating plate comes into contact with the welding area of ​​welding parts one and two, ensuring uniform heating. After heating, the first and second drive devices reverse their direction, causing parts one and two to separate. The lifting device then extends and retracts the heating plate into the slotted opening of the welding table frame. Finally, the first and second drive devices are controlled to move forward, resulting in a tight fit between the welding areas of welding parts one and two. During this contact process, the speed and pressure of the drive devices must be controlled according to the welding process requirements to ensure welding quality.

[0066] After welding is completed, first stop the drive device, then turn off the heating plate. After the welded parts have cooled to a suitable temperature, remove the welded workpiece from the welding sliding assembly, and clean any residual debris from the welding table and welding sliding assembly to prepare for the next welding operation.

[0067] II. Working Principle

[0068] Principle of positioning and fixing welding parts

[0069] The first and second welding sliding assemblies provide the foundation for the installation and positioning of the welding parts. Welding part one and welding part two are respectively fixed on their corresponding sliding assemblies. By setting the sliding assemblies at specific positions on the welding table and cooperating with the strip openings, the welding position of the welding parts can be precisely determined. For example, when the dimensional accuracy of the welding table and sliding assemblies is high, the position of the welding parts in the horizontal direction along the length of the welding table can be effectively controlled. At the same time, additional fixing devices such as clamps can be used to firmly fix the welding parts to the sliding assemblies, preventing displacement of the parts during welding and ensuring the accuracy of the welding position.

[0070] Heating principle

[0071] The distance between the heating plate and the parts to be welded can be adjusted by the lifting device. When the heating plate is energized or supplied with a heating medium, depending on the type of heating plate (e.g., electric heating plate or medium-heated plate), the heating plate begins to heat up and radiate heat outwards. By adjusting the height of the heating plate, the welding area of ​​welding parts one and two can receive heat of appropriate intensity, thereby bringing the material at the welding area to the temperature state required for welding, such as softening or melting the material, so that welding can be achieved under subsequent pressure.

[0072] Drive and welding principles

[0073] The first and second driving devices act on the first and second welding sliding components, respectively. When the driving devices are activated, the driving force they generate pushes the sliding components to move towards each other. For example, if the first driving device is a hydraulic cylinder, the piston rod of the hydraulic cylinder extends and pushes the first welding sliding component towards the second welding sliding component; similarly, the second driving device also pushes the second welding sliding component to move. During their relative movement, welding part one and welding part two gradually approach each other and eventually come into contact. During this contact, due to the pressure applied by the driving devices and the characteristics of the welding material after heating, such as softening and melting, the welding materials of welding part one and welding part two fuse and diffuse with each other, forming a strong welded connection after cooling, thus completing the welding process of non-metallic materials.

[0074] Optionally, the bottom of the welding table frame 3 is provided with a first foot 1 and a first universal wheel 2. Multiple first feet 1 are telescopically and evenly arranged at the bottom edge of the welding table frame 3, and a first universal wheel 2 is provided between adjacent first feet 1. The feet are used to adjust the level of the welding table frame 3, and the first universal wheel 2 is used to move the position of the welding table frame 3.

[0075] Multiple retractable first feet are evenly distributed along the bottom edge of the welding table, allowing for precise adjustment of its level. Ensuring the welding table is level is crucial during welding operations, especially for non-metallic materials requiring high precision. A level welding table maintains a stable relative position for the parts being welded, preventing displacement or angular deviations due to table tilt, thus effectively improving welding quality and yield.

[0076] The casters positioned between adjacent base plates provide excellent mobility for the welding table. Within the workshop or work area, when the welding equipment needs to be moved according to different production layouts or workflows, the casters facilitate quick and easy relocation. Compared to traditional fixed welding equipment, this caster design significantly improves equipment mobility, reduces manpower and time costs associated with equipment handling, and increases production efficiency. Furthermore, when the equipment is not in use, it can be easily moved to a suitable storage location, saving space.

[0077] Optionally, the heating plate 31 can be a rectangular or circular plate. Rectangular heating plates are suitable for welding non-metallic parts with relatively regular shapes, straight edges, or large flat surfaces. For example, when welding long strips of plastic sheet splicing or rectangular composite material components, the rectangular heating plate can have a larger contact area with the parts being welded, ensuring that heat is evenly distributed in the welding area, making the welding process more stable and efficient.

[0078] Optionally, a fixed pulley 38 is provided in the middle of the crossbeam 43, and a winding reel is provided on the output shaft of the motor 36. One end of the flexible chain is wound on the winding reel, and the other end of the flexible chain is fixed to the fixed pulley 38. The motor can precisely wind and unwind the flexible chain by controlling the rotation of the winding reel. Due to the buffering effect of the fixed pulley, the flexible chain can stably pull the crossbeam, thereby driving the lifting device components such as the scissor arm connected to the crossbeam to move, realizing the smooth lifting and lowering of the heating plate. This flexible chain is usually a steel wire rope 37, but it can also be a nylon rope, etc.

[0079] Example 2

[0080] like Figures 1 to 13 As shown, a non-metallic material welding equipment includes all the contents of Embodiment 1. In addition, the lifting device includes a lifting base plate 34, a lifting table 33, two scissor arms 39, a crossbeam 43, a motor 36, and a flexible chain.

[0081] The heating plate 31 is fixed to the top of the lifting table 33 by the fixing bracket 32. The side wall of the fixing bracket 32 ​​is provided with a concave limiting groove. The two fixing brackets 32 are arranged opposite to each other at both ends of the lifting table 33. The two ends of the heating plate 31 are respectively engaged in the concave limiting groove. Then, the heating plate is firmly fixed in the limiting groove by screws passing through the concave limiting groove.

[0082] A sliding groove 44 is provided at one end of the lifting base plate 34 along its length direction. A motor 36 is installed at one end of the bottom surface of the lifting table 33. The lifting table 33 and the lifting base plate 34 are arranged parallel to each other vertically and spaced apart. The motor 36 is located at the end away from the sliding groove 44.

[0083] Two scissor arms 39 are arranged parallel to each other and spaced apart. The bottom of the two scissor arms 39 is fixedly connected to each other by a crossbeam 43. The top of the scissor arms 39 is rotatably connected to the bottom surface of the lifting table 33. One bottom end of the scissor arms 39 is provided with a slide rod, which is slidably disposed in a slide groove 44. The other bottom end of the scissor arms 39 is rotatably connected to the bottom end of the lifting base plate 34 away from the slide groove 44. The motor 36 is located between the two scissor arms 39. The output end of the motor 36 is connected to the middle of the crossbeam 43 through a flexible chain.

[0084] The bottom of the lifting base plate 34 is provided with a second foot 42 and a second universal wheel 41. Multiple second feet 42 are telescopically and evenly arranged at the bottom edge of the lifting base plate 34. A second universal wheel 41 is provided between adjacent second feet 42. The feet are used to adjust the level of the lifting base plate 34, and the first universal wheel 2 is used to move the position of the lifting base plate 34.

[0085] It should be noted that: the electric motor acts as the power source, and the rotation of its output shaft drives the winding reel to rotate. When the winding reel winds up the flexible chain, it pulls the crossbeam upward. Since the second lifting legs at the bottom of the two scissor arms are fixedly connected via the crossbeam, and the sliding rod at the bottom of the second lifting leg of one of the scissor arms slides within a channel steel groove and is positioned by a screw bearing, the upward movement of the crossbeam increases the angle between the scissor arms, i.e., the scissor arms unfold. The top of the scissor arms is rotatably connected to the bottom surface of the lifting table, and the bottom of the first lifting leg is rotatably connected to the lifting base plate via a male and female pin. As the scissor arms unfold, the lifting table rises relative to the lifting base plate, thereby raising the heating plate.

[0086] When the motor reverses direction and the winding reel releases the flexible chain, the crossbeam descends, the scissor arm angle decreases, the lifting table descends, and the heating plate descends as well. By controlling the forward and reverse rotation of the motor, as well as its speed and duration, the lifting height and speed of the heating plate can be precisely controlled to meet the positional requirements of different welding processes.

[0087] The scissor lift arm 39 includes a first lifting leg 391, a second lifting leg 392, and a pivot rod 393. The first lifting leg 391 and the second lifting leg 392 have the same structure. The first lifting leg 391 is located outside the second lifting leg 392. The middle part of the first lifting leg 391 and the middle part of the second lifting leg 392 are rotatably connected by the pivot rod 393. The first lifting leg 391 and the second lifting leg 392 are arranged in a cross shape. The top of the first lifting leg 391 and the second lifting leg 392 are connected to the lifting table 3. The bottom surface of the 3 is rotatably connected, and the bottom of the second lifting leg 392 of the two scissor arms 39 is fixedly connected by the crossbeam 43. The bottom end of the second lifting leg 392 is provided with a sliding rod, which is arranged parallel to the crossbeam 43. A matching sliding groove 44 is opened on one end of the lifting base plate 34. The sliding groove 44 is a channel steel sliding groove. A screw bearing 40 is provided in the sliding groove 44. The end of the sliding rod away from the scissor arm 39 is axially arranged in the screw bearing 40. The bottom end of the first lifting leg 391 is rotatably connected to the other end of the lifting base plate 34 by a male and female nail 35.

[0088] Example 3

[0089] like Figures 1 to 13As shown, a non-metallic material welding device includes all the contents of Embodiment 2. Except that the first welding sliding assembly and the second welding sliding assembly have the same structure, usually L-shaped, and are arranged in a mirror image. Both the first welding sliding assembly and the second welding sliding assembly include a sliding platform 21 and a guide rail 8. Multiple guide rails 8 are arranged horizontally along the length of the welding table frame 3. Multiple universal balls 27 are evenly provided at the bottom of the sliding platform 21. The universal balls 27 and the guide rail 8 slide against each other. The first driving device and the end of the sliding platform 21 of the first welding sliding assembly away from the strip opening 301 are in contact with each other. The second driving device and the end of the sliding platform 21 of the second welding sliding assembly away from the strip opening 301 are in contact with each other.

[0094] Example 5

[0095] like Figures 1 to 13As shown, a non-metallic material welding device includes all the contents of Embodiment 4, and in addition, it includes a fixing device. The fixing device is arranged on the first welding sliding assembly or the second welding sliding assembly along the width direction of the welding table 3. The fixing device is used to fix the parts carried on the first welding sliding assembly or the second welding sliding assembly.

[0096] The fixing device includes two side pressure brackets 25, a pneumatic cylinder 24, and a hand crank screw 23. The two side pressure brackets 25 are arranged opposite each other at both ends of the first welding sliding assembly or the second welding sliding assembly. The outer wall of the part abuts against the inner wall of the side pressure bracket 25. The top of one side pressure bracket 25 is provided with a hand crank screw 23, and the output end of the hand crank screw 23 presses against one side of the top surface of the part. The top of the other side pressure bracket 25 is provided with a pneumatic cylinder 24, and the output end of the pneumatic cylinder 24 presses against the other side of the top surface of the part. The pneumatic cylinder 24 and the hand crank screw 23 are both arranged along the height direction of the welding table 3.

[0097] Two lateral pressure brackets, positioned opposite each other at both ends of the welding sliding assembly, abut against the outer walls of the part from both sides, restricting the horizontal displacement of the part in the width direction of the welding table. This ensures that the part remains in a precise, preset position throughout the preparation stage before welding and during the welding process, preventing positional shifts caused by unexpected external forces, such as slight equipment vibrations or minor collisions during operation.

[0098] The hand-cranked screw and pneumatic cylinder located at the top of the side-pressure bracket press against the part from both sides of its top surface, further restricting its vertical movement and securing it firmly to the welding sliding assembly from all directions. This multi-directional fixing method is crucial for ensuring welding accuracy, especially when welding high-precision non-metallic materials. It ensures the accurate positioning of the weld joint, thereby improving welding quality and reducing welding defects.

[0099] The hand-cranked lead screw is adjustable, allowing operators to manually rotate it to change the extension length of its output end, accommodating welded parts of varying thicknesses or heights. For parts with irregular shapes or varying dimensions, adjusting the hand-cranked lead screw ensures it can always be coordinated with a pneumatic cylinder, achieving reliable fixation of the part.

[0100] The pneumatic cylinder can control the output pressure by adjusting parameters such as air pressure according to actual needs. This ensures that sufficient fixing force is applied to the parts to keep them stable during welding, while also preventing damage to the parts due to excessive pressure. It is especially suitable for soft or pressure-sensitive non-metallic material parts, thereby enhancing the applicability of the entire fixing device to different types of parts.

[0101] During welding, both the minute forces generated by thermal expansion and contraction during heating and the external forces generated when the drive device pushes the welding sliding assembly to bring the parts closer together can cause the parts to wobble. This fixing device, through the coordinated action of the side pressure bracket, hand-cranked screw, and pneumatic cylinder, firmly secures the parts, ensuring they remain stable throughout the entire welding process, including heating and butt joint pressing, preventing wobble or misalignment. This contributes to smooth welding operations and ensures consistent weld quality.

[0102] When two welding parts are brought together by the drive device for welding, the fixing device firmly holds the parts in place, ensuring that the welding pressure is evenly distributed across the weld joint. This prevents pressure concentration in localized areas or uneven pressure due to movement or displacement of the parts, guaranteeing that the welding materials fuse fully under uniform pressure, thus improving the strength of the weld joint and the overall weld quality.

[0103] Operators can easily and precisely adjust the extension length of the hand crank screw by hand according to the actual situation, thereby quickly achieving fine-tuning of the fixation degree of the parts. This manual fine-tuning function is very practical and convenient for welding tasks with high fixation accuracy requirements and small differences in part dimensions. Operators can flexibly achieve the best fixation state of the parts based on their own experience and actual observation.

[0104] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.

Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered within the scope of implementation of this utility model.
