Description

Technical Field

[0001] This utility model relates to a lifting device for solar photovoltaic modules, belonging to the field of photovoltaic construction technology. Background Technology

[0002] Solar photovoltaic (PV) power generation technology is a technology that converts solar energy into electrical energy through photovoltaic panels. PV panels typically utilize the photovoltaic effect principle of semiconductor devices for photoelectric conversion. As a clean energy source, PV power generation systems are gradually being widely used.

[0003] In the construction of photovoltaic power plants, the lifting and transportation of entire photovoltaic panels is a critical step, and the fixing method directly affects the integrity of the modules. Currently, the entire photovoltaic panel is usually placed on a lifting device, which clamps and fixes the photovoltaic panels to position them and prevent them from falling during lifting. However, traditional clamping devices are usually rigid. Rigid clamps fix the entire photovoltaic panel by directly contacting the photovoltaic panel box and applying a certain pressure. Because the material is hard and the contact area is small, the pressure concentration can easily cause local damage to the photovoltaic panels, thereby reducing the safety of the photovoltaic panels during lifting.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a solar photovoltaic module lifting device, which solves the problem that the traditional clamping components in the prior art are usually rigid. The rigid clamps fix the photovoltaic panels in the whole box by directly contacting the photovoltaic panel box and applying a certain pressure. However, the pressure concentration can easily cause local damage to the photovoltaic panels, thereby reducing the safety of the photovoltaic panels during the lifting process.

[0006] The technical problem to be solved by this utility model is achieved by the following technical solution: a solar photovoltaic module lifting device, including a base, with rotating grooves on both sides of the base, and a fixed shaft fixedly connected between the inner walls of the opposite sides of the rotating grooves, with a fixed plate rotatably sleeved on the fixed shaft, a first mounting block fixedly connected to one side of one fixed plate, and a second mounting block fixedly connected to the other fixed plate opposite to the first mounting block, with a positioning groove on the side of the first mounting block near the second mounting block, and a locking block that can be inserted into the positioning groove fixedly connected to the side of the second mounting block near the first mounting block, and a positioning mechanism provided on the second mounting block, which can fix the locking block in the positioning groove;

[0007] Both the second mounting block and the first mounting block have through-hole support grooves. Adjustment blocks are slidably connected in the support grooves. An installation belt is provided between the adjustment blocks on the first and second mounting blocks. Both the second and first mounting blocks are equipped with fixing mechanisms. When lifting, the photovoltaic panel is placed on the base, and pushing the fixing mechanism can drive the installation belt to limit the photovoltaic panel. A limit mechanism is provided on the fixing plate to further limit the photovoltaic panel.

[0008] By adopting the above technical solution, during use, the entire box of solar photovoltaic panels is placed on the base, and then the two fixing plates are rotated to make them vertical. During this process, the locking blocks are inserted into the positioning slots. At this point, under the action of the positioning mechanism, the locking blocks are fixed in the positioning slots, preventing them from detaching. This then secures the two fixing plates to a vertical position. Pushing the fixing mechanism causes the mounting straps to move closer to and contact the entire box of solar photovoltaic panels. As the two mounting straps move relative to each other, they restrain and limit the front and rear sides of the entire box of solar photovoltaic panels, preventing the photovoltaic panels from moving forward. Afterward, the limiting mechanism is rotated, causing it to move closer to the entire solar photovoltaic panel box and contact the box body, thus restricting the photovoltaic panels in the left and right directions and preventing them from moving. With the cooperation of the fixing and limiting mechanisms, the photovoltaic panels are secured. At this point, the lifting device can be used with hoisting ropes to lift the photovoltaic panels, which are then lifted from the device. Because the mounting straps are flexible, the pressure on the solar photovoltaic panels is more evenly distributed, which, compared to rigid restraints, largely avoids damage caused by localized compression, thereby increasing the safety of lifting the photovoltaic panels.

[0009] The present invention is further configured as follows: the positioning mechanism includes a fixed groove unidirectionally opened in the card block, a sliding groove communicating with the positioning groove is opened on the first mounting block, a fixed block with its end capable of being inserted into the fixed groove is slidably arranged in the sliding groove, the side of the fixed block near the card block is inclined, a first spring is fixedly connected between the side of the fixed block away from the card block and the inner wall of the sliding groove, an inner sliding groove is opened on one side of the inner wall of the sliding groove, and a disassembly component that can release the positioning mechanism is provided in the inner sliding groove;

[0010] The disassembly assembly includes a rotating shaft rotatably connected between the inner walls of opposite sides of the inner slide groove, a connecting block slidably connected to the inner slide groove and fixedly connected to the fixing block, one end of the rotating shaft extending out of the first mounting block and fixedly connected to a handle block, and a first pushing block slidably connected to the connecting block and fixedly connected to the rotating shaft.

[0011] By adopting the above technical solution, when the two fixed plates are rotated relative to each other to a vertical state, the locking block is slidably inserted into the positioning groove. During this process, the locking block contacts the inclined surface of the fixed block and pushes the fixed block to slide into the sliding groove. During this process, the fixed block compresses the first spring, causing the first spring to deform. When both fixed plates are rotated to a vertical state, the lower surface of the locking block is in contact with the bottom wall of the positioning groove, and the fixed groove is aligned with the sliding groove. At this time, under the action of the release force of the first spring, the fixed block is slid into the fixed groove, thereby fixing the locking block and preventing it from sliding in the positioning groove, thus positioning the two fixed plates in a vertical state.

[0012] When it is necessary to release the positioning mechanism, turning the handle block will drive the rotating shaft to rotate. The rotating shaft will drive the first pushing block to rotate around the axis of the rotating shaft. During the rotation of the first pushing block, it will contact the connecting block and push the connecting block to move away from the locking block. In this process, the fixing block will move and slide out of the fixing groove, thereby releasing the positioning of the locking block. This will allow the two fixing plates to rotate to a horizontal state, making it convenient to place the entire box of solar photovoltaic panels on the base. The release of positioning is convenient and quick, and the disassembly is carried out by turning the handle block, which is safe and improves the practicality of the lifting device.

[0013] The present invention is further configured such that: the limiting mechanism includes multiple threaded rods threaded onto the fixed plate, the ends of the threaded rods are rotatably connected to the mounting plate via bearings, and a rubber block is fixedly connected to the side of the mounting plate away from the fixed plate.

[0014] By adopting the above technical solution, when the two fixing plates are fixed in a vertical position under the action of the positioning mechanism, rotating the threaded rod will cause the mounting plate to move left and right, thereby causing the rubber block to move synchronously. When the rubber block moves towards the solar photovoltaic panel box, the rubber block will fit against one side of the solar photovoltaic panel box and apply appropriate pressure to the box, thereby restricting the photovoltaic panel and preventing it from moving left and right. Because the rubber block is made of rubber with a certain degree of elasticity, the restriction of the photovoltaic panel by the rubber block has a certain buffering effect, which is more gentle than the traditional rigid restriction, avoiding damage to the photovoltaic panel during the lifting process, thereby further improving the safety of lifting the photovoltaic panel.

[0015] The present invention is further configured as follows: the fixing mechanism includes a second push block fixedly connected to the adjusting block; a connecting groove is provided through the mounting plate and the rubber block; a limiting slide groove is provided on one side of the second push block located on the second mounting block; a limiting slide post is fixedly connected to one end of the mounting belt and slidably connected to the limiting slide groove; the other end of the mounting belt is fixedly connected to the second push block located on the first mounting block; multiple adjusting grooves are provided on the side of the adjusting block near the locking block; a guide groove is provided on the inner wall of one side of the stabilizing groove; a positioning block that can be inserted into any one of the adjusting grooves is slidably connected in the guide groove; a second spring is fixedly connected between the side of the positioning block away from the adjusting block and the inner wall of the guide groove; and an unlocking component is provided on the positioning block for releasing the fixing mechanism from limiting the photovoltaic panel.

[0016] The unlocking component includes a horizontal block that is fixedly connected to the positioning block. The first mounting block and the second mounting block are provided with a support groove that communicates with the inside of the guide groove on the side away from the mounting plate. The horizontal block slides out of the outside of the first mounting block or the second mounting block through the support groove. The surface of the positioning block away from the second spring is inclined.

[0017] By adopting the above technical solution, in the initial state, the limiting slide post is not inserted into the limiting slide groove. When the two fixing plates are fixed in a vertical state, the limiting slide post is inserted into the limiting slide groove. With the cooperation of the limiting slide post and the limiting slide groove, the limiting slide post can only be pulled out upwards and cannot be pulled out in the left or right direction. Since the side surface of the positioning block away from the second spring is inclined, the adjusting block can only move in one direction. When the adjusting block is pushed towards the box of solar photovoltaic panels, the inner wall of one side of the adjusting groove slides into contact with the inclined surface of the positioning block. The inner wall of one side of the adjusting groove pushes the positioning block, pushing it into the guide groove. During this process, the positioning block squeezes the second spring, causing the second spring to deform. As the adjusting block moves, the positioning block gradually detaches from the current adjusting groove and, under the action of the second spring, inserts into the next adjusting groove aligned with the guide groove.

[0018] Therefore, when the adjusting block moves closer to the solar photovoltaic panel box, the mounting belt is simultaneously moved closer to the solar photovoltaic panel box. During this process, the mounting belt gradually contacts the solar photovoltaic panel box and applies appropriate binding pressure. When both mounting belts are in contact with and binding the solar photovoltaic panel box, the photovoltaic panels are restricted in the front-to-back direction, preventing them from moving forward or backward. This avoids forward or backward movement of the solar photovoltaic panels during lifting. Furthermore, because the mounting belt is flexible, the pressure of the mounting belt binding the photovoltaic panels is more evenly distributed. Compared to rigid binding, this can largely avoid damage caused by localized compression of the photovoltaic panels, thus increasing the safety of lifting the photovoltaic panels. Additionally, pushing the adjusting block allows the positioning block to insert into different adjusting slots, thereby adjusting the binding pressure of the mounting belt on the solar photovoltaic panel box and the distance between the two mounting belts. This allows the two mounting belts to restrict solar photovoltaic panels of different sizes, increasing the practicality of the lifting device.

[0019] When the horizontal block is pushed to slide away from the adjusting block, the positioning block is simultaneously driven to slide out of the adjusting groove, thereby allowing the adjusting block to move back and forth, and thus releasing the positioning of the fixing mechanism.

[0020] The present invention is further configured such that: a positioning ring is fixedly connected to the fixing plate, a lifting rope is tied to the positioning ring, and a rubber base is fixedly connected to the lower side of the base.

[0021] By adopting the above technical solution, the lifting rope is used to fix the crane hook by binding, hooking or other methods when lifting a whole box of solar photovoltaic panels.

[0022] The beneficial effects of this utility model are as follows: Because the rubber block is made of rubber with a certain degree of elasticity, it provides a certain buffering effect on the restriction of the photovoltaic panel. Furthermore, the rubber block has a large area and fits snugly against the photovoltaic panel housing, making it more gentle than traditional rigid restrictions, thus preventing damage to the photovoltaic panel during lifting. Also, because the mounting strap is flexible, the pressure of the mounting strap binding the photovoltaic panel is more evenly distributed, which, compared to rigid restraint, can largely prevent damage caused by localized compression of the photovoltaic panel, thereby increasing the safety of lifting the photovoltaic panel. Moreover, pushing the adjusting block allows the positioning block to insert into different adjusting slots, thereby adjusting the pressure of the mounting strap binding the entire solar photovoltaic panel housing and adjusting the distance between the two mounting straps. This allows the two mounting straps to restrict solar photovoltaic panels of different sizes, thus increasing the practicality of the lifting device. Attached Figure Description

Detailed Implementation

[0031] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following details... Figure 1-6 As shown, this utility model is further illustrated.

[0032] like Figure 1-4As shown, this utility model is a lifting device for solar photovoltaic modules, including a base 1. Rotating grooves 2 are provided on both opposite sides of the base 1. A fixed shaft 3 is fixedly connected between the inner walls of the opposite sides of the rotating groove 2. The axial direction of the fixed shaft 3 is consistent with the extension direction of the rotating groove 2. A fixed plate 4 is rotatably sleeved on the fixed shaft 3. The fixed plate 4 is slidably connected to the rotating groove 2. The rotating groove 2 allows the fixed plate 4 to rotate to a maximum of 90 degrees. When the fixed plate 4 is rotated from a horizontal state to a vertical state, the fixed plate 4 is blocked by the rotating groove 2 and cannot continue to rotate. A first mounting block 8 is fixedly connected to one side of one fixed plate 4. A second mounting block 9 is fixedly connected to the other fixed plate 4 and is disposed opposite to the first mounting block 8. A positioning groove 11 is provided on the side of the first mounting block 8 near the second mounting block 9. A locking block 10 that can be inserted into the positioning groove 11 is fixedly connected on the side of the second mounting block 9 near the first mounting block 8. A positioning mechanism is provided on the second mounting block 9, which can fix the locking block 10 in the positioning groove 11. Both the second mounting block 9 and the first mounting block 8 have through-hole support grooves 30. Adjustment blocks 32 are slidably connected within the support grooves 30. An mounting strap 26 is provided between the adjustment blocks 32 on the first mounting block 8 and the second mounting block 9. Both the second mounting block 9 and the first mounting block 8 are equipped with fixing mechanisms. When lifting, the photovoltaic panel is placed on the base 1, and pushing the fixing mechanism drives the mounting strap 26 to limit the photovoltaic panel's position. A limiting mechanism is provided on the fixing plate 4 to further limit the photovoltaic panel's position.

[0033] In use, place the entire box of solar photovoltaic panels on the base 1, then rotate the two fixing plates 4 to make them vertical. During this process, the locking block 10 is inserted into the positioning groove 11. At this time, under the action of the positioning mechanism, the locking block 10 is fixed in the positioning groove 11, so that the locking block 10 cannot be dislodged from the positioning groove 11. Then, the two fixing plates 4 are fixed in a vertical position. At this time, push the fixing mechanism to make the fixing mechanism move the mounting belt 26 closer to the entire box of solar photovoltaic panels and make contact with the entire box of solar photovoltaic panels. As the two mounting belts 26 move relative to each other, they can restrain and limit the front and rear sides of the box of solar photovoltaic panels, so that the photovoltaic panels cannot enter. The system moves back and forth, at which point the limiting mechanism rotates, causing it to move closer to the solar photovoltaic panels in the entire box and contact the box body, thus restricting the photovoltaic panels in the left and right directions and preventing them from moving left and right. With the cooperation of the fixing mechanism and the limiting mechanism, the photovoltaic panels are fixed. At this time, the lifting device can be used with the lifting rope 12 to lift the photovoltaic panels that are limited on the lifting device. Because the installation strap 26 is flexible, the pressure of the installation strap 26 binding the solar photovoltaic panels in the entire box is more evenly distributed. Compared with rigid binding, it can largely avoid damage caused by local compression of the photovoltaic panels, thereby increasing the safety of lifting the photovoltaic panels.

[0034] like Figure 1-4 As shown, the positioning mechanism includes a fixed groove 15 unidirectionally opened in the locking block 10. The fixed groove 15 is opened on the side of the locking block 10 near the first mounting block 8. The first mounting block 8 is provided with a sliding groove 16 communicating with the positioning groove 11. A fixing block 17 with its end inserted into the fixed groove 15 is slidably arranged in the sliding groove 16. The side of the fixing block 17 near the locking block 10 is inclined. In this solution, the inclined surface of the fixing block 17 can be an arc inclined surface or an inclined plane. A first spring 18 is fixedly connected between the surface of the fixing block 17 away from the locking block 10 and the inner wall of the sliding groove 16. The extension path of the first spring 18 is consistent with the movement path of the fixing block 17. An inner sliding groove 21 is opened on one side of the inner wall of the sliding groove 16. A disassembly component that can release the positioning mechanism is provided in the inner sliding groove 21.

[0035] like Figure 4As shown, the disassembly assembly includes a rotating shaft 20 rotatably connected between the inner walls of opposite sides of the inner slide groove 21, a connecting block 19 slidably connected to the inner slide groove 21 and fixedly connected to the fixing block 17, the connecting block 19 being located on the side of the rotating shaft 20 away from the locking block 10, the surface of the connecting block 19 away from the fixing block 17 being slidably connected to the inner wall of the inner slide groove 21, one end of the rotating shaft 20 extending through the first mounting block 8 and fixedly connected to a handle block 22, a first pushing block 23 slidably connected to the rotating shaft 20 and connected to the connecting block 19, and the inclined surface of the fixing block 17 inclined from the fixing block 17 to the first spring 18 in a direction away from the rotating shaft 20.

[0036] When the two fixed plates 4 are rotated relative to each other to a vertical position, the locking block 10 is slidably inserted into the positioning groove 11. During this process, the locking block 10 comes into contact with the inclined surface of the fixed block 17 and pushes the fixed block 17 into the sliding groove 16. During this process, the fixed block 17 compresses the first spring 18, causing the first spring 18 to deform. When both fixed plates 4 are rotated to a vertical position, the lower surface of the locking block 10 is in contact with the bottom wall of the positioning groove 11, and the fixed groove 15 is aligned with the sliding groove 16. At this time, under the action of the release force of the first spring 18, the fixed block 17 is slid into the fixed groove 15, thereby fixing the locking block 10 and preventing it from sliding in the positioning groove 11, thus positioning the two fixed plates 4 in a vertical position.

[0037] When it is necessary to release the positioning mechanism, rotating the handle block 22 can drive the rotating shaft 20 to rotate. The rotating shaft 20 drives the first pushing block 23 to rotate around the axis of the rotating shaft 20. During the rotation, the first pushing block 23 contacts the connecting block 19 and pushes the connecting block 19 to move away from the locking block 10. During this process, the fixing block 17 is moved, causing the fixing block 17 to slide out of the fixing groove 15, thereby releasing the positioning of the locking block 10. This allows the two fixing plates 4 to rotate to a horizontal state, making it convenient to place the entire box of solar photovoltaic panels on the base 1. The release of positioning is convenient and quick, and the disassembly is carried out by rotating the handle block 22, which is safe and improves the practicality of the lifting device.

[0038] like Figure 1-2 As shown, the limiting mechanism includes multiple threaded rods 7 threaded onto the fixed plate 4. The ends of the threaded rods 7 are rotatably connected to the mounting plate 5 via bearings. A rubber block 6 is fixedly connected to the side of the mounting plate 5 away from the fixed plate 4.

[0039] When the two fixing plates 4 are fixed in a vertical position by the positioning mechanism, the threaded rod 7 is rotated. The rotation of the threaded rod 7 drives the mounting plate 5 to move left and right, thereby driving the rubber block 6 to move synchronously. When the rubber block 6 moves towards the solar photovoltaic panel box, the rubber block 6 will adhere to one side of the solar photovoltaic panel box and apply appropriate pressure to the box, thereby restricting the photovoltaic panel and preventing it from moving left and right. Because the rubber block 6 is made of rubber with a certain degree of elasticity, the restriction of the photovoltaic panel has a certain buffering effect. In addition, the rubber block 6 has a large area and adheres to the photovoltaic panel box, so it is more flexible than the traditional rigid restriction, avoiding damage to the photovoltaic panel during the lifting process, thereby further improving the safety of lifting the photovoltaic panel.

[0040] like Figure 1-6 As shown, the fixing mechanism includes a second pushing block 34 fixedly connected to the adjusting block 32. Connecting grooves 14 are provided through both the mounting plate 5 and the rubber block 6. The second pushing block 34 is slidably connected to the fixing plate 4. A limiting slide groove 24 extending from the upper surface of the second pushing block 34 located on the second mounting block 9 is provided on one side. A limiting slide post 25, which is slidably connected to the limiting slide groove 24, is fixedly connected to one end of the mounting belt 26. The limiting slide post 25 is cylindrical. The limiting slide groove 24 is slidably fitted onto the limiting slide post 25. The area of ​​the limiting slide groove 24 covering the limiting slide post 25 exceeds the radius of the limiting slide post 25. With the cooperation of the limiting slide post 25 and the limiting slide groove 24, the limiting slide post 25 can only be pulled out upwards and cannot be pulled out in the left or right direction. Furthermore, when the limiting slide post 25 is inserted into the limiting slide groove 24... When the groove 24 is in place, the mounting strip 26 is not in a taut state, allowing the limiting slide post 25 to be completely pulled out from the limiting slide groove 24. The other end of the mounting strip 26 is fixedly connected to the second push block 34 located on the first mounting block 8. The mounting strip 26 is made of woven and sewn fabric strips. The adjusting block 32 has multiple adjusting grooves 33 on the side near the locking block 10. The inner wall of one side of the stabilizing groove 27 has a guide groove 28. A positioning block 36 that can be inserted into any one of the adjusting grooves 33 is slidably connected in the guide groove 28. A second spring 29 is fixedly connected between the side of the positioning block 36 away from the adjusting block 32 and the inner wall of the guide groove 28. The extension path of the second spring 29 is consistent with the movement path of the positioning block 36. The positioning block 36 is provided with an unlocking component for releasing the limiting mechanism on the photovoltaic panel.

[0041] like Figure 5-6As shown, the unlocking component includes a horizontal block 31 fixedly connected to the positioning block 36. The first mounting block 8 and the second mounting block 9 are both provided with a support groove 30 communicating with the inside of the guide groove 28 on the side away from the mounting plate 5. The horizontal block 31 slides out of the outside of the first mounting block 8 or the second mounting block 9 through the support groove 30. The surface of the positioning block 36 away from the second spring 29 is inclined. The inclined surface of the positioning block 36 is inclined from the horizontal block 31 to the positioning block 36 towards the direction close to the adjusting block 32.

[0042] Initially, the limiting slide post 25 is not inserted into the limiting slide groove 24. When the two fixing plates 4 are fixed in a vertical position, the limiting slide post 25 is inserted into the limiting slide groove 24. With the cooperation of the limiting slide post 25 and the limiting slide groove 24, the limiting slide post 25 can only be pulled out upwards and cannot be pulled out in the left or right direction. Also, because the surface of the positioning block 36 away from the second spring 29 is inclined, this means that the adjusting block 32 can only move in one direction. When the adjusting block 32 is pushed towards the box body closer to the solar photovoltaic panels, When the direction is moved, the inner wall of one side of the adjusting groove 33 is slidably connected to the inclined surface of the positioning block 36, and the inner wall of one side of the adjusting groove 33 pushes the positioning block 36, pushing the positioning block 36 into the guide groove 28. During this process, the positioning block 36 squeezes the second spring 29, causing the second spring 29 to be squeezed and deformed. As the adjusting block 32 moves, the positioning block 36 gradually gets out of the current adjusting groove 33, and under the action of the second spring 29, it is inserted into the next adjusting groove 33 that is aligned with the guide groove 28.

[0043] Therefore, when the adjusting block 32 moves towards the box of solar photovoltaic panels, it simultaneously moves the mounting belt 26 towards the box of solar photovoltaic panels. During this process, the mounting belt 26 gradually contacts the box of solar photovoltaic panels and applies appropriate binding pressure. When both mounting belts 26 are in contact with and binding the box of solar photovoltaic panels, the photovoltaic panels are restricted in the front-back direction, preventing the entire box of solar photovoltaic panels from moving forward or backward. This avoids forward or backward movement of the entire box of solar photovoltaic panels during lifting. The flexible installation strap 26 allows for a more even distribution of pressure on the photovoltaic panels, which, compared to rigid straps, largely avoids damage caused by localized compression of the photovoltaic panels, thus increasing the safety of lifting them. Furthermore, pushing the adjusting block 32 allows the positioning block 36 to insert into different adjusting slots 33, thereby adjusting the pressure of the installation strap 26 on the entire solar photovoltaic panel enclosure and also adjusting the distance between the two installation straps 26. This allows the two installation straps 26 to restrain solar photovoltaic panels of different sizes, increasing the practicality of the lifting device.

[0044] When the horizontal block 31 is pushed to slide away from the adjusting block 32, the positioning block 36 is simultaneously driven to slide out of the adjusting groove 33, thereby allowing the adjusting block 32 to move back and forth, and thus releasing the positioning of the fixing mechanism.

[0045] like Figure 1 As shown, a positioning ring 13 is fixedly connected to the fixed plate 4, and a lifting rope 12 is tied to the positioning ring 13. A rubber base 35 is fixedly connected to the lower side of the base 1.

[0046] The lifting rope 12 is used to fix the entire box of solar photovoltaic panels to the hook of the crane by means of binding, hooking or other methods when lifting the entire box of solar photovoltaic panels.

[0047] The photovoltaic (PV) panel modules in this solution are mainly whole boxes of solar PV panels, i.e., PV panels in boxes with packaging. They contain multiple solar panels, not individual PV panels. This solution does not apply to the lifting of individual PV panels without packaging boxes.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model.
