[0020] This utility model also proposes a wire feeder, comprising:

[0021] The housing forms an installation space with an opening;

[0022] A wire feeding device, wherein the wire feeding device is disposed in the installation space;

[0023] The door body includes a main body and a folded edge structure folded inward relative to the main body; and

[0024] As described in any of the preceding embodiments, the first connector of the hinge structure is connected to the inner wall of the housing on the opening side, and the second connector of the hinge structure is located on the inner side of the folded edge structure and connected to the folded edge structure.

The first connecting section extends from the other end of the bent section toward the first connecting part, thereby forming a clearance space with an opening on one side by the first connecting section and the bent section. With this arrangement, when the hinge structure is applied to a wire feeder, the bent section can cross the folded edge structure of the door body, so that the first connecting section, the second connector, and the pivot are all located on the side of the folded edge structure facing the door body. When the door body is opened and closed, the folded edge structure and the second connector can rotate together to enter and exit the clearance space, so that the presence of the folded edge structure will not affect the rotation of the second connector relative to the first connector. In other words, the technical solution of this utility model can utilize the clearance space to avoid the folding structure of the door body, so that the hinge structure can be installed inside the wire feeder, avoiding the hinge assembly from being exposed when the wire feeder closes the door, thereby reducing the risk of the hinge structure being damaged by the external environment, and also making the appearance of the wire feeder relatively neat and beautiful.

[0047] This utility model proposes a hinge structure 1, which allows the hinge structure 1 to be installed inside the wire feeder 100, reducing the risk of damage to the hinge structure 1 due to external environmental influences.

[0048] Please see Figures 1 to 9 In one embodiment of the present invention, the hinge structure 1 includes a first connector 11, a pivot 13, and a second connector 12. The first connector 11 includes a bent section 111 and at least one first connecting section 112. One end of the bent section 111 is provided with a first connecting portion 1113. The first connecting section 112 extends from the other end of the bent section 111 toward the first connecting portion 1113 and is spaced apart from the first connecting portion 1113. The bent section 111 and the first connecting section 112 enclose a clearance space 113. The pivot 13 is located at one end of the first connecting section 112 near the first connecting portion 1113. The second connector 12 is rotatably connected to the first connector 11 through the pivot 13. At least a portion of the second connector 12 can rotate in and out of the clearance space 113. The second connector 12 is provided with a second connecting portion 123.

[0049] In this embodiment, the hinge structure 1 can be applied in the wire feeder 100. The wire feeder 100 includes a housing 2 and a door 3 rotatably connected by the hinge structure 1. The housing 2 forms an accommodating space with an opening, and the door 3 is rotatably openable and closable. The door 3 includes a door body 31 and a folded edge structure 32 connected to the door body 31. The folded edge structure 32 may only include a first folded edge 321 connected to the door body 31, or it may include a first folded edge 321 and a second folded edge 322 connected to each other. Optionally, the door 3 can rotate horizontally relative to the housing 2, or it can flip vertically relative to the housing 2.

[0050] The first connector 11 in the hinge structure 1 is used to connect with the housing 2. The first connector 11 includes a bent section 111 and a first connecting section 112 connected together. The shape and outline of the bent section 111 can be a curved arc outline, or the bent section 111 can be formed by connecting two bent structures. One end of the bent section 111 is provided with a first connecting part 1113 for connecting with the housing 2. The first connecting part 1113 can be provided as a through hole for threading screws or other connectors, or as a plug-in post for insertion into a plug-in hole provided on the side wall of the housing 2. Alternatively, the first connecting part 1113 can be provided with an adhesive surface or solder pad for bonding or welding. The first connecting section 112 is connected to the end of the bent section 111 away from the first connecting part 1113. The other end of the first connecting section 112 extends towards the first connecting part 1113 and is spaced apart from the first connecting part 1113, and is provided with a first pivot hole 1121. This configuration means that the first connector 11 is set as an open-loop structure with an opening on one side, so that a clearance space 113 is formed on the inner side of the first connector 11.

[0051] The second connector 12 is used to connect with the door body 3. The second connector 12 is provided with a second pivot hole 124. The pivot 13 passes through the first pivot hole 1121 and the second pivot hole 124, so that the second connector 12 and the first connecting section 112 are rotatably connected by the pivot 13, allowing the second connector 12 to rotate relative to the first connector 11, and the second connector 12 to rotate in and out of the clearance space 113 of the first connector 11. Alternatively, the pivot 13 can be fixed to the first connector 11, and the second connector 12 can be rotatably connected to the pivot 13; or the pivot 13 can be fixed to the second connector 12, and the pivot 13 can be rotatably connected to the first connector 11. The second connector 12 is provided with a second connecting part 123 for connecting with the door body 3. The second connecting part 123 can be a through hole for a screw or other locking element 4, or it can be a plug-in structure, an adhesive structure, or a welded structure. The second connector 12 can be connected to the door body 31 of the door 3, or to the folded edge structure 32 of the door 3.

[0052] When the hinge structure 1 is applied to the wire feeder 100, the bent section 111 of the first connecting member 11 is connected to the inner wall of the housing 2 through the first connecting part 1113. The bent section 111 crosses the folded edge structure 32 of the door body 3, so that the first connecting section 112 is located on the side of the folded edge structure 32 facing the door body 31. With this arrangement, when the door body 3 rotates and opens relative to the housing 2, the folded edge structure 32 can rotate in the clearance space 113; when the door body 3 is closed, since the hinge structure 1 is located inside the wire feeder 100, the hinge structure 1 is not exposed to the outside, thereby reducing the risk of damage to the hinge structure 1 due to the influence of the external environment, and making the appearance of the wire feeder 100 relatively simple and beautiful, with no excessive exposed parts.

[0053] That is, in the technical solution of this utility model, the hinge structure 1 includes a first connecting member 11 and a second connecting member 12 rotatably connected by a pivot 13. The first connecting member 11 includes a bent section 111 and a first connecting section 112. One end of the bent section 111 is provided with a first connecting part 1113 that can be connected to the housing 2. The first connecting section 112 extends from the other end of the bent section 111 toward the first connecting part 1113, so that the first connecting section 112 and the bent section 111 enclose and form a clearance space with an opening on one side. In this configuration, when the hinge structure 1 is applied to the wire feeder 100, the bending section 111 can cross the folded edge structure 32 of the door body 3, so that the first connecting section 112, the second connecting member 12, and the pivot 13 are all located on the side of the folded edge structure 32 facing the door body 31. When the door body 3 is opened and closed, the folded edge structure 32 and the second connecting member 12 can rotate together to enter and exit the clearance space 113, thus preventing the second connecting member 12 from being affected by the presence of the folded edge structure 32 relative to the first connecting member 11. In other words, the technical solution of this utility model can utilize the clearance space 113 to avoid the folded edge structure 32 of the door body 3, thereby allowing the hinge structure 1 to be installed inside the wire feeder 100, preventing the hinge assembly from being exposed when the wire feeder 100 is closed, thereby reducing the risk of damage to the hinge structure 1 due to external environmental influences, and also making the appearance of the wire feeder 100 relatively neat and beautiful.

[0054] Please see Figure 6 and Figure 7 In one embodiment, the hinge structure 1 further includes a torsion spring 14, which is sleeved on the pivot 13 and located between the first connecting section 112 and the second connecting member 12. The two ends of the torsion spring 14 form a first lever arm 141 and a second lever arm 142, respectively. The first lever arm 141 is connected to the first connecting section 112, and the second lever arm 142 is connected to the second connecting member 12.

[0055] In this embodiment, a torsion spring 14 is provided in the hinge structure 1. When the second connecting member 12 rotates relative to the first connecting member 11, the torsion spring 14 will twist. The connection between the first lever arm 141 and the first connecting segment 112 can be a plug-in connection as described in the following embodiment, or it can be connected by adhesive or binding. The second lever arm 142 and the second connecting member 12 can be connected to each other by plug-in connection, adhesive or binding.

[0056] In practical applications, when the second connector 12 is in the first position, the torsion spring 14 can remain in its original shape, that is, the torsion spring 14 does not twist or deform at this time; during the process of rotating the second connector 12 to the second position, the torsion spring 14 generates torsion and elastic force. When the force applied to the second connector 12 is removed, the torsion spring 14 returns to its original shape and can drive the second connector 12 to automatically return to the first position; with this setting, when the hinge structure 1 is applied to the wire feeder 100, the door body 3 can have the effect of automatically returning to the closing position, improving the ease of use.

[0057] Alternatively, the torsion spring 14 can remain in its original state when the second connector 12 is in the second position. During the process of rotating the second connector 12 to the first position, the torsion spring 14 generates torsion and elastic force. When the force applied to the second connector 12 is removed, the torsion spring 14 returns to its original state and can drive the second connector 12 to automatically return to the second position. With this configuration, when the hinge structure 1 is applied to the wire feeder 100, the door 3 can have the effect of automatic opening. When it is necessary to open the door 3, releasing the lock on the door 3 will allow the door 3 to open automatically, improving the convenience of use.

[0058] Please see Figure 6 and Figure 7 In one embodiment, the surface of the first connecting segment 112 facing the torsion spring 14 is provided with a first insertion hole 1122, and the first lever arm 141 is inserted into the first insertion hole 1122. This arrangement facilitates the connection between the first lever arm 141 and the first connecting segment 112, and the first lever arm 141 inserted into the first insertion hole 1122 can maintain a relatively stable relative position relationship, avoiding the first lever arm 141 from being misaligned relative to the first connecting segment 112.

[0059] Please see Figure 6 and Figure 7 In one embodiment, the surface of the second connector 12 facing the torsion spring 14 is provided with a second insertion hole 125, and the second lever arm 142 is inserted into the second insertion hole 125. This arrangement facilitates the connection between the second lever arm 142 and the second connector 12, and the second lever arm 142 inserted into the second insertion hole 125 can maintain a relatively stable relative position relationship, avoiding the second lever arm 142 from being misaligned relative to the second connector 12.

[0060] Please see Figure 6 and Figure 7 In one embodiment, the first connector 11 is provided with at least two first connecting segments 112, the at least two first connecting segments 112 are spaced apart along the length direction of the rotating shaft 13, and a portion of the second connector 12 is located between the two first connecting segments 112.

[0061] In this embodiment, the second connector 12 can be configured as a plate-like structure, with one side of the plate-like structure located between the two first connecting segments 112; alternatively, the second connector 12 can be configured as a frame structure formed by a fixed segment 122 and at least two second connecting segments 121 as described in the following embodiment. In this case, the two second connecting segments 121 can be positioned between the two first connecting segments 112, or the at least two first connecting segments 112 and the at least two second connecting segments 121 can be staggered. In this embodiment, the pivot 13 passes through the two first connecting segments 112; this configuration can improve the connection strength between the pivot 13 and the first connector 11, and can prevent the first connector 11 and the second connector 12 from overlapping too much in the length direction of the pivot 13, thus reducing the size of the hinge structure 1.

[0062] Please see Figure 6 and Figure 7 In one embodiment, the second connector 12 includes a fixed section 122 and at least two second connecting sections 121. The at least two second connecting sections 121 are spaced apart along the length direction of the rotating shaft 13. The rotating shaft 13 passes through one end of the second connecting section 121, and the other end of the second connecting section 121 is connected to the fixed section 122. At least one first connecting section 112 is located between the two second connecting sections 121.

[0063] In this embodiment, the second connector 12 is provided with two second connecting segments 121 spaced apart along the length of the rotating shaft 13, and the two second connecting segments 121 are respectively connected to the rotating shaft 13. Optionally, when the first connector 11 is provided with at least two first connecting segments 112, the two first connecting segments 112 can be located between the two second connecting segments 121, or the at least two first connecting segments 112 and the at least two second connecting segments 121 can be staggered, which is not limited here. The ends of the two second connecting segments 121 away from the rotating shaft 13 are respectively connected to the fixed segment 122. The setting of the fixed segment 122 can make the second connector 12 form an integral structure, avoid the two second connecting segments 121 being set separately, and improve the structural strength of the second connector 12. In addition, when the second connector 12 rotates to the inside of the clearance space 113, the fixed segment 122 can abut against the first connecting segment 112, thereby limiting the rotation angle. When the hinge structure 1 is applied to the wire feeder 100, it can limit the opening angle of the door 3.

[0064] See also Figures 3 to 5 In one embodiment, the second connector 12 is provided with a second connecting hole as a second connecting part 123.

[0065] In this embodiment, the second connector 12 is detachably connected to the door body 3 via a screw or other locking element 4 and the folded edge structure 32 of the door body 3. The folded edge structure 32 has a locking hole corresponding to the second connecting hole. When the second connector 12 needs to be connected to the door body 3, the fixing hole and the second connecting hole are aligned, and the screw or other locking element 4 is inserted into the locking hole and the second connecting hole, thereby connecting the second connector 12 to the folded edge structure 32. Optionally, when a screw is used as the locking element 4, the second connecting hole can be a screw hole; the locking element 4 may also be unthreaded, for example, using a rivet to engage with the second connecting hole, which is not limited here.

[0066] In this embodiment, the folded edge structure 32 of the door body 3 may only have a first folded edge 321 connected to the door body 31. In this case, a locking hole is provided on the first folded edge 321, and a second connecting hole is provided on the surface of the second connector 12 opposite to the first folded edge 321. When the folded edge structure 32 includes a first folded edge 321 and a second folded edge 322 connected together, the locking hole may be provided on the first folded edge 321 or on the second folded edge 322; when the locking hole is provided on the second folded edge 322, the second connecting hole is provided on the end face of the second connector 12 away from the rotating shaft 13.

[0067] Please see Figure 5 In one embodiment, the second connecting hole is provided on the end face of the second connector 12 away from the rotating shaft 13.

[0068] In this embodiment, the folded edge structure 32 provided on the door body 3 includes a first folded edge 321 and a second folded edge 322, wherein the first folded edge 321 is connected to the door body 31, the second folded edge 322 is disposed opposite to the door body 31, and a locking hole is provided on the second folded edge 322 for being disposed opposite to the second connecting hole. This configuration allows for easy installation and removal of the locking element 4 from the inner surface of the door body 3 when installing or removing the hinge structure 1 from the door body 3, without needing to remove it from the first fold edge 321. This provides a relatively large operating space. Furthermore, when the hinge structure 1 is connected to the housing 2, removing or installing the hinge structure 1 from the door body 3 requires the door body 3 to be in an open position relative to the housing 2. In this case, the first fold edge 321 is obstructed by the housing 2, making removal and installation from the first fold edge 321 inconvenient. However, by placing the locking hole on the second fold edge 322 and correspondingly placing the second connecting hole on the end face of the second connector 12, interference from the housing 2 during hinge structure 1 removal and installation is avoided, improving the ease of installation and removal of the hinge structure 1.

[0069] See also Figure 4 and Figure 5 In one embodiment, the bent section 111 is provided with a clearance hole 1114, and the second connector 12 can be rotated to the clearance space 113 so that at least one second connecting hole is opposite to the clearance hole 1114.

[0070] In this configuration, when the hinge structure 1 is connected to the door body 3, the second connector 12 rotates with the folded edge structure 32 of the door body 3 to the inside of the clearance space 113 of the first connector 11. The locking hole on the second folded edge 322, as well as the connection hole and clearance hole 1114 of the second connector 12, are on the same straight line, and the connection position between the second folded edge 322 and the second connector 12 is not blocked by the first connector 11. At this time, the locking member 4 can be inserted into the locking hole and the second connection hole through the clearance hole 1114, and tools such as screwdrivers can also be inserted through the clearance hole 1114 to lock the locking member 4. When it is necessary to remove the hinge structure 1 from the door body 3, tools such as screwdrivers can also be inserted through the clearance hole 1114 to remove the locking member 4. This improves the convenience of installing and removing the hinge structure 1 from the door body 3.

[0071] Please see Figure 4 and Figure 5 In one embodiment, at least one second connecting hole is offset from the first connecting member 11 along the length direction of the pivot 13. This arrangement avoids the first connecting member 11 from obstructing the positions of the second connecting member 12 and the second folded edge 322, thereby improving the convenience of assembling and disassembling the hinge structure 1 on the door body 3.

[0072] In one embodiment, the hinge structure 1 is provided with at least two second connecting holes, and the second folded edge 322 is provided with at least two locking holes corresponding to each of the second connecting holes to improve the connection strength. Each of the second connecting holes can be exposed through the clearance holes 1114 provided on the bent section 111 for easy disassembly and assembly of the locking member 4; or each of the second connecting holes can be offset from the first connecting member 11 in the length direction of the rotating shaft 13; or some of the second connecting holes can be exposed through the clearance holes 1114, while other second connecting holes are offset from the first connecting member 11 in the length direction of the rotating shaft 13. No specific limitations are made here.

[0073] Please see Figure 6 and Figure 7In one embodiment, the rotating shaft 13 is fixedly connected to the second connecting member 12, allowing the rotating shaft 13 and the second connecting member 12 to rotate synchronously relative to the first connecting member 11. The connection between the second connecting member 12 and the rotating shaft 13 can be an interference fit or a threaded fit. In some embodiments, the second connecting member 12 and the rotating shaft 13 can also be connected by bolts 15. For example, a threaded hole can be provided on the end face of the rotating shaft 13, and the bolt 15 is threaded into the threaded hole, with the bolt head pressing tightly against the surface of the second connecting member 12, thereby fixing the rotating shaft 13 and the second connecting member 12 together.

[0074] In one embodiment, the fixed section 122 is provided with a stop protrusion, which forms a stop surface. When the second connecting member 12 rotates to the second position, the stop surface abuts and fits against the surface of the first connecting section 112. This arrangement increases the contact area between the second connecting member 12 and the first connecting member 11 when the second connecting member 12 rotates to the second position, allowing the fixed section 122 and the first connecting section 112 to better cooperate and play a limiting role.

[0075] Please see Figure 5 In one embodiment, the bent section 111 includes an arc-shaped structure 1111 and a connecting structure 1112. The arc-shaped structure 1111 is centered on the axis of the rotating shaft 13. The two ends of the arc-shaped structure 1111 are respectively connected to the connecting structure 1112 and the first connecting section 112. The connecting structure 1112 is provided with a first connecting part 1113.

[0076] In this embodiment, the bending segment 111 includes an arc-shaped structure 1111 that conforms to the rotation trajectory of the end of the second connector 12, and a connecting structure 1112 connected to the arc-shaped structure 1111. The first connecting segment 112 and the connecting structure 1112 are respectively connected to the two ends of the arc-shaped structure 1111. The connecting structure 1112 can extend along the tangent direction of the end of the arc-shaped structure 1111, or it can extend outward from the arc-shaped structure 1111. A first connecting portion 1113 is provided on the connecting structure 1112. Compared with other bending shapes, the arc-shaped structure 1111 is relatively small in size, which can reduce the volume of the hinge structure 1, thereby reducing the space occupied by the hinge structure 1 in the wire feeder 100.

[0077] Please see Figure 5 In one embodiment, the bent section 111 is provided with at least one first connecting hole as a first connecting part 1113. In this embodiment, an mounting hole can be provided on the inner wall of the housing 2 for being positioned opposite to the first connecting hole, so that the first connecting member 11 can be detachably connected to the housing 2 by screws or other connecting members, which facilitates disassembly and assembly.

[0078] Please see Figure 1 and Figure 2This utility model also proposes a wire feeder 100, which includes a housing 2, a wire feeding device (not shown), a door 3, and a hinge structure 1. The housing 2 forms an installation space with an opening; the wire feeding device is disposed in the installation space; the door 3 includes a door body 31 and a folded edge structure 32 folded inward relative to the door body 31; the first connecting member 11 of the hinge structure 1 is connected to the inner wall of the housing 2 on the opening side, and the second connecting member 12 of the hinge structure 1 is located inside the folded edge structure 32 and connected to the folded edge structure 32. The specific structure of the hinge structure 1 is as described in the above embodiment. The housing 2 has an installation space, and the housing 2 has at least one opening communicating with the installation space; the door 3 is rotatably connected to the housing 2 via the hinge structure 1, and the door 3 can rotate horizontally or flip vertically relative to the housing 2. The door body 3 includes a door main body 31 and a folded edge structure 32 disposed on the side of the door main body 31. The folded edge structure 32 is located at least on the side where the door body 3 is rotatably connected to the housing 2, or it can be arranged around the door main body 31. The folded edge structure 32 includes a first folded edge 321 disposed perpendicular to the door main body 31. Optionally, the folded edge structure 32 may also include a second folded edge 322 connected to the first folded edge 321 and disposed opposite to the door main body 31. A wire feeding device is used to provide and transport welding wire. The wire feeder 100 can be used in conjunction with welding equipment to provide welding wire to the welding position for welding.

[0079] In this embodiment, the bent section 111 of the first connector 11 is connected to the inner wall of the housing 2 through the first connecting part 1113. The bent section 111 crosses the folded edge structure 32, so that the first connecting section 112 and the second connector 12 are both located on the side of the folded edge structure 32 facing the door body 31. The second connector 12 is connected to the folded edge structure 32 through the second connecting part 123. The folded edge structure 32 can also rotate in and out of the clearance space 113 formed by the first connector 11, which can avoid the hinge structure 1 being interfered with by the folded edge structure 32 of the edge of the door body 3 when it is installed inside the door body 3 and the housing 2, so that the hinge structure 1 can be installed inside the door body 3.

[0080] Optionally, the housing 2 may be provided with one, two or more openings and one, two or more doors 3; each door 3 may be provided in a one-to-one correspondence with each opening, or two doors 3 may be provided in a correspondence with one opening to form a double door structure.

[0081] Since the wire feeder 100 proposed in this utility model adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0082] Please see Figure 2 and Figure 4In one embodiment, the folded edge structure 32 includes a first folded edge 321 and a second folded edge 322 connected to each other. The first folded edge 321 is connected to the door body 31, and the second folded edge 322 is disposed opposite to the door body 31. The folded edge structure 32 and the door body 31 enclose a receiving space, and the second connecting member 12 is disposed in the receiving space. With this arrangement, when the door 3 is in the open state, the second connecting member 12 and the pivot 13 are housed in the receiving space, which can reduce the risk of damage to the second connecting member 12 and the pivot 13.

[0083] Please see Figure 3 and Figure 4 In one embodiment, the second folded edge 322 is provided with a locking hole, which is disposed opposite to the second connecting hole provided on the end face of the second connector 12. The wire feeder 100 also includes a locking member 4, which is inserted into the locking hole and the second connecting hole so that the second connector 12 is connected to the second folded edge 322.

[0084] In this embodiment, a second connecting hole is provided on the end face of the second connector 12 away from the pivot 13, and a locking hole is provided on the second folded edge 322 for being opposite to the second connecting hole. This arrangement allows the locking member 4 to be installed and removed from the inner surface of the door body 3 when the hinge structure 1 is installed on or removed from the door body 3, without needing to be installed and removed from the first folded edge 321. This provides a relatively large operating space, avoids interference from the housing 2 when installing or removing the hinge structure 1, and improves the ease of installation and removal of the hinge structure 1.

[0085] Please see Figure 4 In one embodiment, the second folded edge 322 is provided with a clearance opening 323, and the first connecting segment 112 passes through the clearance opening 323. This arrangement eliminates the need for a longer bending segment 111, thereby reducing the volume of the first connecting member 11 and the hinge structure 1.

[0086] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
