Description

Technical Field

[0001] This utility model relates to the field of welding wire storage technology, and in particular to a mobile welding wire storage moisture-proof device. Background Technology

[0002] Welding wire is a metal wire used as filler metal or as a conductor for welding. The warehouse for storing welding wire should have a dry and ventilated environment, avoiding moisture and the presence of highly volatile and corrosive substances such as water, acid, and alkali. It is also not advisable to store welding wire in the same warehouse as these substances.

[0003] Existing pure aluminum welding wire is usually packaged in coils, with a common capacity of about seven kilograms, which is relatively large. However, once the welding wire is opened and exposed to air, its rust prevention time will be greatly shortened. The existing welding wire packaging is basically a one-time plastic seal, which cannot be restored after opening. Therefore, in humid air, the opened welding wire often becomes ineffective and unusable before it is used up, resulting in frequent waste of welding wire. Therefore, this utility model provides a mobile welding wire storage and moisture-proof device to meet the needs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a mobile welding wire storage and moisture-proof device. By setting up a sealed box, a closed space is formed inside, which delays the natural wear and tear of the welding wire and reduces the waste of welding wire. The above settings can solve the problem of frequent waste of welding wire.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A mobile welding wire storage and moisture-proof device includes a sealed box. Two fixed plates are fixedly connected to both ends of one side of the sealed box. A first limiting block is fixedly connected to one side of each fixed plate. A limiting frame is slidably connected to the outer wall of the fixed plate. A movable hole is opened on one side of the limiting frame, and the first limiting block is disposed in the movable hole. Second limiting blocks are fixedly connected to both sides of one end of the fixed plate. A rotating shaft is disposed between the two second limiting blocks. The rotating shaft is fixedly connected to the sealed box. Two sealing plates are rotatably connected to the middle of the rotating shaft. One side of the two sealing plates is in contact with each other. The limiting frame is movably sleeved with the two sealing plates. A sealing gasket is fixedly connected to one side of each sealing plate. A first spring is fixedly connected between the two sealing plates. A discharge hole is opened at one end of the sealed box. The sealing gasket corresponds to the discharge hole. A welding wire reel storage assembly is disposed inside the sealed box.

[0006] Optionally, the storage assembly includes a fixed shaft fixedly connected to the sealed box, the welding wire spool being movably sleeved with the fixed shaft, and sealing doors rotatably connected to both sides of the sealed box. One side of the sealing door is tightly fitted to the sealed box via a sealing ring, and a first connecting plate is fixedly connected to one side of the sealing door. A second connecting plate is rotatably connected to one end of the first connecting plate, and a positioning block is fixedly connected to the outer wall of the sealed box. The positioning block is movably engaged with the second connecting plate.

[0007] Optionally, the positioning block is a rectangular block, and a positioning frame is rotatably connected to one side below the positioning block. The positioning frame includes a rotating shaft and a limiting plate. The rotating shaft is fixedly connected to the limiting plate and rotatably connected to the positioning block. The limiting plate is abutted against one side of the second connecting plate.

[0008] Optionally, the limiting frame is a C-shaped frame, and one side of the rotating shaft, the sealing plate, the second limiting block, and the fixing plate are all located on the same plane.

[0009] Optionally, the second limiting block is a triangular block, and one side of the second limiting block is in contact with the sealing plate.

[0010] Optionally, a third limiting block is fixedly connected to the inner wall of one end of the limiting frame. The third limiting block corresponds to the sealing gasket and the discharge hole. One side of the third limiting block is in contact with the sealing gasket. The two sealing gaskets form a complete circle. The discharge hole is a circular hole. The diameter of the sealing gasket is larger than the diameter of the discharge hole.

[0011] Optionally, a partition is fixedly connected to the middle of the sealed box, a number of self-locking casters are fixedly connected to the bottom of the sealed box, a push handle is fixedly connected to one end of the sealed box, and a pull rod is fixedly connected to one side of the limiting frame.

[0012] Optionally, both ends of the inner wall of the sealed box are fixedly connected to a limiting frame. One end of the limiting frame is movably sleeved with a limiting rod. One end of the limiting rod is fixedly connected to a second spring. The second spring is fixedly connected to the limiting frame. The limiting rod is an L-shaped rod. One end of the limiting rod is movably engaged with the welding wire spool.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects: In the above scheme, by setting a rotating shaft to limit the rotation direction of the sealing plate and a second limiting block to limit the rotation range of the sealing plate, the sealing plate will rotate around the rotating shaft under the drive of the first spring after the external force is removed. Due to the limitation of the second limiting block, the two sealing plates form a V shape, so that the welding wire of the welding wire spool placed in the sealing box can be pulled out from between the two sealing gaskets through the discharge hole to the outside of the sealing box for use. When the welding wire is not in use, the limiting frame is pushed to move along the fixed plate, so that the limiting frame squeezes the sealing plate, which in turn causes the sealing plate to drive the sealing gasket to close, so that the sealing gasket is in contact with the welding wire, restricting the position of the welding wire, and forming a sealed space in the sealing box, delaying the natural wear and tear of the welding wire, thereby extending the service life of the welding wire, reducing the occurrence of welding wire scrap due to prolonged exposure to air, and reducing the waste of welding wire.

[0014] The sealed box is divided into two independent spaces by a partition, allowing two welding wire reels to be placed inside at the same time, which is convenient for two people to use at the same time. The sealed box can also move the welding wire reels according to the needs of use, improving the ease of use. The rotation of the welding wire reels is restricted by the limit rod, so that the welding wire reels will not rotate when not in use or during movement, which facilitates the movement of the sealed box and the welding wire reels and the storage of the welding wire reels.

[0024] like Figures 1 to 6 As shown, an embodiment of this utility model provides a mobile welding wire storage and moisture-proof device, including a sealed box 1. Two fixed plates 2 are fixedly connected to both ends of one side of the sealed box 1. A first limiting block 3 is fixedly connected to one side of the fixed plate 2. A limiting frame 5 is slidably connected to the outer wall of the fixed plate 2. A moving hole 4 is opened on one side of the limiting frame 5, and the first limiting block 3 is disposed in the moving hole 4. A second limiting block 6 is fixedly connected to both sides of one end of the fixed plate 2. A rotating shaft 7 is arranged between the two second limiting blocks 6. The rotating shaft 7 is fixedly connected to the sealed box 1. Two sealing plates 8 are rotatably connected to the middle of the rotating shaft 7. One side of the two sealing plates 8 is in contact with each other. The limiting frame 5 is movably sleeved with the two sealing plates 8. A sealing gasket 9 is fixedly connected to one side of the sealing plate 8. A first spring 11 is fixedly connected between the two sealing plates 8. A discharge hole 10 is opened at one end of the sealed box 1, and the sealing gasket 9 corresponds to the discharge hole 10.

[0025] like Figures 4-6As shown, a storage assembly for a welding wire reel 15 is provided inside the sealed box 1. The storage assembly includes a fixed shaft 14 fixedly connected to the sealed box 1. The welding wire reel 15 is movably sleeved with the fixed shaft 14. Sealing doors 16 are rotatably connected to both sides of the sealed box 1. One side of the sealing door 16 is tightly fitted to the sealed box 1 through a sealing ring. A first connecting plate 17 is fixedly connected to one side of the sealing door 16. A second connecting plate 19 is rotatably connected to one end of the first connecting plate 17. A positioning block 18 is fixedly connected to the outer wall of the sealed box 1. The positioning block 18 is movably engaged with the second connecting plate 19. The positioning block 18 is a rectangular block. A positioning frame 20 is rotatably connected to one side below the positioning block 18. The positioning frame 20 includes a rotating shaft 201 and a limiting plate 202. The rotating shaft 201 is fixedly connected to the limiting plate 202 and rotatably connected to the positioning block 18. The limiting plate 202 is fitted to one side of the second connecting plate 19.

[0026] like Figures 1-3 As shown, the limiting frame 5 is a C-shaped frame. The rotating shaft 7, the sealing plate 8, the second limiting block 6, and one side of the fixing plate 2 are all located on the same plane. The second limiting block 6 is a triangular block. One side of the second limiting block 6 is attached to the sealing plate 8. A third limiting block 12 is fixedly connected to the inner wall of one end of the limiting frame 5. The third limiting block 12 corresponds to the sealing gasket 9 and the discharge hole 10. One side of the third limiting block 12 is attached to the sealing gasket 9. The two sealing gaskets 9 form a complete circle. The discharge hole 10 is a circular hole. The diameter of the sealing gasket 9 is larger than the diameter of the discharge hole 10.

[0027] In use, two fixing plates 2 are fixedly connected to both ends of one side of the sealing box 1. A first limiting block 3 is fixedly connected to one side of the fixing plate 2, so that the sealing box 1 restricts the position of the fixing plate 2, thereby fixing the position of the first limiting block 3. A limiting frame 5 is slidably connected to the outer wall of the fixing plate 2. A moving hole 4 is opened on one side of the limiting frame 5. The first limiting block 3 is set in the moving hole 4, so that the fixing plate 2 restricts the sliding distance of the limiting frame 5 through the first limiting block 3 and the moving hole 4, preventing the connection between the limiting frame 5 and the fixing plate 2 from breaking. A second limiting block 6 is fixedly connected to both sides of one end of the fixing plate 2. A rotating shaft 7 is set between the two second limiting blocks 6. The rotating shaft 7 is fixedly connected to the sealing box 1. Two sealing plates 8 are rotatably connected to the middle of the rotating shaft 7. The sealing box 1 restricts the rotation direction of the sealing plate 8 via the rotating shaft 7, and the second limiting block 6 restricts the rotation range of the sealing plate 8. The limiting frame 5 is movably connected to the two sealing plates 8, with one side of the two sealing plates 8 touching each other. After the limiting frame 5 is connected to the sealing plate 8, the two sealing plates 8 can fit together. A sealing gasket 9 is fixedly connected to one side of the sealing plate 8, and a first spring 11 is fixedly connected between the two sealing plates 8, so that the relative position of the sealing plate 8 and the sealing gasket 9 is fixed. After the sealing plate 8 loses the external force, it will rotate around the rotating shaft 7 under the drive of the first spring 11. Due to the limitation of the second limiting block 6, the two sealing plates 8 form a V shape. A discharge hole 10 is opened at one end of the sealing box 1, and the sealing gasket 9 corresponds to the discharge hole 10.

[0028] The sealed box 1 is equipped with a storage assembly for the welding wire spool 15. After the sealing plate 8 moves the sealing gasket 9, the welding wire of the welding wire spool 15 placed in the sealed box 1 is pulled out from between the two sealing gaskets 9 through the discharge hole 10 to the outside of the sealed box 1 for use. When the welding wire is not in use, the limiting frame 5 is pushed to move along the fixed plate 2, so that the limiting frame 5 squeezes the sealing plate 8, thereby causing the sealing plate 8 to close the sealing gasket 9, so that the sealing gasket 9 fits against the welding wire, restricting the position of the welding wire, and forming a sealed space inside the sealed box 1, which delays the natural wear and tear of the welding wire, thereby extending the service life of the welding wire, reducing the occurrence of the welding wire being scrapped due to prolonged exposure to air, and reducing the waste of welding wire.

[0029] The storage components include a fixed shaft 14 fixedly connected to the sealed box 1, and a welding wire spool 15 movably sleeved with the fixed shaft 14. This allows the sealed box 1 to restrict the position of the welding wire spool 15 through the fixed shaft 14 without affecting the use of the welding wire spool 15. Both sides of the sealed box 1 are rotatably connected to sealing doors 16. One side of the sealing door 16 is tightly fitted to the sealed box 1 through a sealing ring, so that the sealing door 16 can seal the inner cavity of the sealed box 1, thereby reducing the oxidation process of the welding wire and extending the storage time of the welding wire after unsealing.

[0030] A first connecting plate 17 is fixedly connected to one side of the sealing door 16, and a second connecting plate 19 is rotatably connected to one end of the first connecting plate 17. A positioning block 18 is fixedly connected to the outer wall of the sealing box 1. The positioning block 18 is movably engaged with the second connecting plate 19, so that the sealing box 1 restricts the position of the second connecting plate 19 through the positioning block 18, thereby restricting the position of the first connecting plate 17 and the sealing door 16, so that the sealing door 16 remains in contact with the sealing box 1. The positioning block 18 is a rectangular block, and a positioning frame 20 is rotatably connected to one side below the positioning block 18, so that the limiting plate can fix the position of the second connecting plate 19 after it is engaged with the positioning block 18. When the sealing box 1 and the sealing door 16 shake, the engagement of the positioning block 18 and the second connecting plate 19 remains stable and is not easy to loosen. Moreover, the engagement of the limiting plate 202 with the second connecting plate 19 can be disengaged by rotating the limiting plate 202 180 degrees. The operation is simple and convenient and easy to use.

[0031] The limiting frame 5 is a C-shaped frame, and the rotating shaft 7, sealing plate 8, second limiting block 6, and one side of the fixing plate 2 are all located on the same plane. This ensures that after the limiting frame 5 moves along the fixing plate 2, it will engage with the two sealing plates 8, changing the state of the two sealing plates 8. The second limiting block 6 is a triangular block, and one side of the second limiting block 6 is in contact with the sealing plate 8, so that the second limiting block 6 can limit the rotation angle of the sealing plate 8. A third limiting block 12 is fixedly connected to the inner wall of one end of the limiting frame 5. The third limiting block 12 corresponds to the sealing gasket 9 and the discharge hole 10. One side of the third limiting block 12 is in contact with the sealing gasket 9, and the two sealing gaskets 9 form a complete circle. The discharge hole 10 is a circular hole, so that when the limiting frame 5 moves, it will drive the third limiting block 12 to move and fit with the sealing gasket 9. This will push the sealing gasket 9 and the discharge hole 10 to fit tightly, thereby improving the sealing effect inside the sealing box 1.

[0032] As one implementation method in this embodiment, such as Figure 1 , Figures 4 to 6As shown, a partition 13 is fixedly connected to the middle of the sealed box 1, and several self-locking casters 101 are fixedly connected to the bottom of the sealed box 1. A push handle 102 is fixedly connected to one end of the sealed box 1. A pull rod 501 is fixedly connected to one side of the limiting frame 5. Limiting frames 21 are fixedly connected to both ends of the inner wall of the sealed box 1. A limiting rod 23 is movably sleeved at one end of the limiting frame 21. A second spring 22 is fixedly connected to one end of the limiting rod 23. The second spring 22 is fixedly connected to the limiting frame 21. The limiting rod 23 is an L-shaped rod. One end of the limiting rod 23 is movably engaged with the welding wire reel 15. The partition 13 fixedly connected to the middle of the sealed box 1 divides the inner cavity of the sealed box 1 into two independent spaces, allowing two welding wire reels 15 to be placed in the sealed box 1 at the same time, facilitating simultaneous use by two people. Several self-locking casters are fixedly connected to the bottom of the sealed box 1, and a push handle 102 is fixedly connected to one end of the sealed box 1. The handle allows the sealing box 1 to move the welding wire reel 15 according to usage requirements, improving ease of use. A pull rod 501 is fixedly connected to one side of the limiting frame 5, facilitating the movement of the limiting frame 5. Limiting frames 21 are fixedly connected to both ends of the inner wall of the sealing box 1, fixing the position of the limiting frames 21. A limiting rod 23 is movably sleeved at one end of the limiting frame 21, and a second spring 22 is fixedly connected to one end of the limiting rod 23. The second spring 22 is fixedly connected to the limiting frame 21, so that the limiting frame 21 and the second spring 22 cooperate to limit the movement of the limiting rod 23. The limiting rod 23 is an L-shaped rod, and one end of the limiting rod 23 is movably engaged with the welding wire reel 15, so that the limiting rod 23 restricts the rotation of the welding wire reel 15, thus preventing the welding wire reel 15 from rotating when not in use or during movement, facilitating the movement of the sealing box 1 and the welding wire reel 15 and the storage of the welding wire reel 15.

[0033] The working principle of the technical solution provided by this utility model is as follows: In use, the sealing box 1 restricts the rotation direction of the sealing plate 8 by the rotating shaft 7, and the second limiting block 6 restricts the rotation range of the sealing plate 8. The relative position of the sealing plate 8 and the sealing gasket 9 is fixed so that the sealing plate 8 will rotate around the rotating shaft 7 under the drive of the first spring 11 after the external force is removed. Due to the limitation of the second limiting block 6, the two sealing plates 8 form a V shape, so that the welding wire of the welding wire spool 15 placed in the sealing box 1 is pulled out from between the two sealing gaskets 9 through the discharge hole 10 to the outside of the sealing box 1 for use. When the welding wire is not in use, the limiting frame 5 is pushed to move along the fixed plate 2, so that the limiting frame 5 squeezes the sealing plate 8, so that the sealing plate 8 drives the sealing gasket 9 to close, so that the sealing gasket 9 fits with the welding wire, restricts the position of the welding wire, and forms a sealed space in the sealing box 1, which delays the natural wear and tear of the welding wire, thereby extending the service life of the welding wire, reducing the occurrence of the welding wire being scrapped due to prolonged exposure to air, and reducing the waste of welding wire.

[0034] The inner cavity of the sealed box 1 is divided into two independent spaces by the partition 13, which allows two welding wire reels 15 to be placed in the sealed box 1 at the same time, making it convenient for two people to use at the same time. It also allows the sealed box 1 to move the welding wire reels 15 according to the use needs, improving the ease of use. The rotation of the welding wire reels 15 is restricted by the limiting rod 23, so that the welding wire reels 15 will not rotate when not in use or during movement, which facilitates the movement of the sealed box 1 and the welding wire reels 15 and the storage of the welding wire reels 15.

[0035] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
