Description

Technical Field

[0001] The utility model relates to the technical field of welding wire packaging, in particular to a welding wire packaging structure. Background Art

[0002] The welding wire is wound on a wire reel and then placed in a cardboard box for easy transportation. In the case of small-scale personal use, a small-diameter welding wire reel is generally purchased and taken out for use. However, if the daily usage is small, a reel of less welding wire will also be used for a long time. The welding wire is exposed to the outside for a long time and is easily damaged or contaminated. Contamination, wire breakage, etc. are not conducive to later use. In addition, after the welding wire reel is placed on the operating table, it is generally not equipped with a fixing device. The small welding wire reel cannot be rotated around the axis. During the process of extracting the welding wire, the welding wire reel will continue to move horizontally, which is inconvenient to use. In the existing technology, there is a lack of protection and fixing devices for small welding wire reels.

[0003] In the prior art, the problem of lack of protection and fixation for small welding wire reels needs to be solved. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a welding wire packaging structure for the above-mentioned technical deficiencies, which solves the problem that small welding wire reels lack protection and fixation.

[0005] The technical solution adopted by the utility model is to provide a welding wire packaging structure, including a welding wire reel, which includes a bottom plate, a vertical tube and a top plate from bottom to top, and also includes:

[0006] A storage tube having an accommodating cavity therein for accommodating a welding wire reel;

[0007] There are two bottom plates, which are rotatably arranged at the lower end of the storage tube in a double-door manner, and the bottom plates rotate toward the inside of the accommodating cavity;

[0008] An upper sealing door is rotatably arranged on the upper end of the storage tube;

[0009] The central axis is set in the accommodating cavity for lifting, and the vertical tube is sleeved on the central axis. There are positioning grooves on the left and right sides of the lower part of the central axis. After the bottom plate is rotated into the accommodating cavity, the ends of the bottom plate on both sides respectively abut against the positioning grooves on both sides to lift the welding wire reel. After the welding wire reel is lifted, the upper end of the welding wire reel is higher than the upper end of the storage tube.

[0010] To further optimize this technical solution, the end of the base plate close to the central axis has an inclined support surface, and after the two base plates are horizontally connected, a triangular groove is formed between the two support surfaces; the lower end of the central axis has a triangular bar that is adapted to be plugged into the triangular groove, and the triangular bar is used to be plugged into the triangular groove.

[0011] To further optimize the technical solution, the front and rear sides of the triangular bar are respectively in contact with the front and rear inner walls of the storage tube.

[0012] To further optimize the technical solution, the vertical tube is rotated relative to the central axis and is raised and lowered. When the end of the bottom plate abuts against the top wall of the positioning groove, the chassis abuts against the end of the bottom plate.

[0013] To further optimize the technical solution, the upper sealing door has two top plates, and the two top plates are rotatably arranged at the upper end of the storage tube in the form of a double door.

[0014] To further optimize the technical solution, a semi-circular clamping plate is provided on one side of the lower end of the top plate. After the two top plates are horizontally docked, the clamping plate is inserted into the interior of the vertical pipe.

[0015] Further optimization of this technical solution also includes:

[0016] The anti-slip rubber sleeve is sleeved on the lower side of the outer portion of the storage tube.

[0017] To further optimize this technical solution, the storage tube is a square frame structure.

[0018] The beneficial effects of the present invention are:

[0019] 1. The upper sealing door and bottom plate can seal the storage tube and protect the internal wire reel, reducing the possibility of damage to the wire reel due to long-term exposure;

[0020] 2. The two bottom plates can be flipped upwards to lift the wire reel upwards, exposing the storage tube, making it easier to take out the welding wire. The wire reel is located inside the storage tube, which still provides a certain degree of protection.

[0021] 3. The bottom plate is in contact with the central axis to position the central axis in height and horizontally. The welding wire reel rotates around the central axis to reduce the horizontal movement of the welding wire reel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0034] To simplify the drawings, only the parts relevant to the utility model are schematically shown in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0035] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0036] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0037] like Figure 1-10 As shown, a welding wire packaging structure includes a welding wire reel 1, which includes a base plate 101, a vertical tube 102 and a top plate 103 from bottom to top, and also includes: a storage tube 2, which has an accommodating chamber 201 inside, and the accommodating chamber 201 is used to accommodate the welding wire reel 1; a bottom plate 3, which has two, and the two bottom plates 3 are rotatably arranged at the lower end of the storage tube 2 in the form of a double door, and the bottom plate 3 rotates toward the inside of the accommodating chamber 201; an upper sealing door 4, which is rotatably arranged at the upper end of the storage tube 2; a central axis 5, which is lifted and lowered in the accommodating chamber 201, and the vertical tube 102 is sleeved on the central axis 5, and the left and right sides of the lower part of the central axis 5 are provided with positioning grooves 501. After the bottom plate 3 rotates into the accommodating chamber 201, the ends of the bottom plates 3 on both sides respectively abut against the positioning grooves 501 on both sides, which are used to lift the welding wire reel 1. After the welding wire reel 1 is lifted, the upper end of the welding wire reel 1 is higher than the upper end of the storage tube 2.

[0038] When in use or stored, the wire reel 1 is placed in the storage tube 2 for storage, and the upper sealing door 4 and the bottom plate 3 seal the upper and lower sides to protect the wire reel 1. When using the welding wire, the two bottom plates 3 are in the form of double doors and can be rotated into the accommodating chamber 201. When the bottom plate 3 is pushed upward from the bottom, the central axis 5 is pushed upward and rises, and then the upper sealing door 4 is pushed open (the upper sealing door 4 can also be opened manually first). Finally, the ends of the bottom plate 3 abut against the positioning grooves 501 on the left and right sides of the lower part of the central axis 5, and abut against the top wall 5011 of the positioning groove 501, supporting and positioning the height of the central axis 5. The central axis 5 can rotate or not. At this time, the lower part of the central axis 5 is pressed against the end of the bottom plate 3, and the bottom plate 3 cannot move towards the middle, so that the height positioning of the central axis 5 can be achieved, and the left and right horizontal directions are limited. After the central axis 5 rises, the wire reel 1 follows and rises above the storage tube 2.

[0039] After use, lift the central axis 5 upwards (you can carry the wire reel 1 by hand or pinch the central axis 5 with your fingers from the vertical tube 102, etc.), and the two ends of the bottom plates 3 will lose the obstruction in the middle and can be rotated downward to reset to the horizontal docking state, and then the wire reel 1 can enter the storage tube 2.

[0040] The central axis 5 can be a full-length axis, and its sidewalls can have several annular grooves to reduce friction with the inner wall of the vertical tube 102. The positioning groove 501 can be D-shaped or annular. When D-shaped, the positioning groove 501 has a top wall 5011 and vertical sidewalls. The end of the bottom plate 3 abuts against both the top wall 5011 and the vertical sidewalls, thereby limiting the rotation of the central axis 5.

[0041] A limit block may be provided on the inner wall of the storage tube 2. When the bottom plate 3 flips upward, in order to prevent the bottom plate 3 from rotating upward by too large an angle and moving away from the positioning groove 501, the limit block abuts against the bottom plate 3 to limit the maximum angle of the bottom plate 3 rotating upward.

[0042] The rotation connection structure between the bottom plate 3 and the upper sealing door 4 is a prior art.

[0043] Furthermore, the end of the base plate 3 close to the central axis 5 has an inclined support surface 301. After the two base plates 3 are horizontally connected, a triangular groove 302 is formed between the two support surfaces 301; the lower end of the central axis 5 has a triangular bar 502 that is adapted to be plugged into the triangular groove 302, and the triangular bar 502 is used to be plugged into the triangular groove 302.

[0044] During use, after the inclined support surface 301 is flipped upward, the support surface 301 can abut against the top wall 5011 of the positioning groove 501. After the bottom plate 3 is horizontally connected, a triangular groove 302 is formed between the two support surfaces 301, and the triangular bar 502 at the lower end of the central axis 5 is inserted into the triangular groove 302, which can stabilize the horizontal state of the bottom plate 3, the central axis 5 is more stable, and the welding wire reel 1 is more stable.

[0045] Furthermore, the front and rear sides of the triangular bar 502 respectively abut against the front and rear inner walls of the storage tube 2 .

[0046] During use, after the front and rear sides of the triangular bar 502 abut against the front and rear inner walls of the storage tube 2 , the triangular bar 502 can still be raised and lowered, thereby limiting the rotation of the central axis 5 and making the central axis 5 more stable.

[0047] Furthermore, the vertical tube 102 is rotated and raised relative to the central axis 5 . When the end of the bottom plate 3 abuts against the top wall 5011 of the positioning groove 501 , the chassis 101 abuts against the end of the bottom plate 3 .

[0048] When in use, the vertical tube 102 can be fixed up and down relative to the central axis 5 (the upper and lower direction limits are existing technology), and there is a height gap between the lower end of the chassis 101 and the lower end of the central axis 5. The lower end of the chassis 101 is flush with the top wall 5011 of the positioning groove 501. At this time, the height of the storage tube 2 is at least not less than the height of the wire reel 1 plus the height of the positioning groove 501.

[0049] If vertical tube 102 is liftable relative to central axis 5, when storing the wire spool 1, the lower end of base plate 101 is aligned with the lower end of central axis 5, and the height of storage tube 2 is at least equal to that of wire spool 1. When welding wire is used, central axis 5 is raised, and wire spool 1 is also raised. Simultaneously, wire spool 1 is raised relative to central axis 5, and the lower end of base plate 101 moves to the top wall 5011 of positioning groove 501.

[0050] Furthermore, the upper sealing door 4 has two top plates 401 , and the two top plates 401 are rotatably arranged at the upper end of the storage tube 2 in the form of a double door.

[0051] When in use, the upper sealing door 4 can be a single door panel or a double door opening form. When the central axis 5 and the welding wire reel 1 rise, the two top panels 401 can be pushed open, saving the door opening action. After the top panels 401 are pushed open, the top panels 401 can abut against the side of the top plate 103.

[0052] Furthermore, a semi-annular clamping plate 4011 is provided on one side of the lower end of the top plate 401 . After the two top plates 401 are horizontally docked, the clamping plate 4011 is inserted into the interior of the vertical pipe 102 .

[0053] During use, when the top plate 401 is rotated to a horizontal position and docked, the upper end of the storage tube 2 is closed, and the two semi-annular clamping plates 4011 are docked into a ring and inserted into the vertical tube 102 at the same time. The outer wall of the clamping plate 4011 abuts against the inner wall of the vertical tube 102, which can position the top plate 401.

[0054] Furthermore, it also includes: an anti-slip rubber sleeve 6, which is sleeved on the lower side of the outer side of the storage tube 2.

[0055] When in use, the anti-skid rubber sleeve 6 is annular and is sleeved on the lower side of the outer wall of the storage tube 2. The lower end of the anti-skid rubber sleeve 6 abuts against the plane of the operating table to improve the positioning ability and prevent the storage tube 2 from sliding randomly.

[0056] Furthermore, the storage tube 2 is a square frame structure.

[0057] When in use, the cardboard box is generally square, and the square frame storage tube 2 can be directly placed in the cardboard box for packaging and transportation. The square frame storage tube 2 is also convenient for rotating the bottom plate 3, which can rotate inside the storage tube 2.

[0058] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
