Description

Technical Field

[0001] The present application relates to the technical field related to electric heating knives, and in particular to an electric heating knife with a bracket. Background Art

[0002] Hot knives are handheld tools that use electricity to generate heat for cutting. There are two types of hot knives. One type incorporates a heating wire inside the blade that generates heat when powered. This type offers advantages such as affordability, low cost, and a simple structure. The other type utilizes the resistance of the blade to generate heat by passing a high current. These handheld hot knives have a very fast preheating time, reaching a red-hot state in just a few seconds, resulting in high efficiency. Hot knives can be used to cut foam plastics, foam glue, plastics, rubber, insulating paper, insulating cloth, cloth, leather, fabric, and more.

[0003] During continuous cutting operations, when workers need to adjust the cutting position of the object, they need to temporarily place the electric knife on the table. This is not convenient for workers to pick up and put down, and they may accidentally pick up the blade end of the electric knife, resulting in burns. On the other hand, the heated blade may burn other items placed on the table when placed on the table. Utility Model Content

[0011] In some embodiments of the present application, the support frame includes a first connecting section, a second connecting section, two supporting parts arranged at intervals along the first direction X, and a connecting structure connected between the two supporting parts. A stop platform is also protruding from the side wall. When the first connecting section and the second connecting section respectively abut against the corresponding first limiting plate, the stop platform and the first limiting plate are respectively located on both sides of the support frame.

[0035] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0036] In the description of this application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0037] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout this application, unless otherwise specified, "plurality" means two or more.

[0038] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections, direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0039] This application provides an electric hot knife with a bracket, the structure of which is described in detail below. It should be noted that the order in which the following embodiments are described does not limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the description of each embodiment has its own focus. For parts not detailed in one embodiment, please refer to the relevant description of other embodiments.

[0040] Reference Figure 1 and Figure 2The electric hot knife with a bracket provided in the present application includes a handle 1, which includes a connecting portion 11 and a gripping portion 12. The connecting portion 11 is connected to a knife clamp 2, to which a blade 3 is connected. The connecting portion 11 has two side walls 111 arranged opposite each other in a first direction X. Both side walls 111 are provided with a first limiting portion and a second limiting portion, with the first limiting portion being closer to the knife clamp 2 relative to the second limiting portion. The electric hot knife also includes a bracket 4, which has a first rotating shaft 41 and a second rotating shaft 42, and a support frame 43 connected between the first rotating shaft 41 and the second rotating shaft 42. The first rotating shaft 41 and the second rotating shaft 42 are respectively rotatably connected to the two side walls 111. The rotation angle of the support frame 43 is jointly limited by the first limiting portion and the second limiting portion. The rotation axis of the first rotating shaft 41 and the rotation axis of the second rotating shaft 42 coincide and are both parallel to the first direction X. Among them, when the support frame 43 cooperates with the first limiting portion, the ends of the support frame 43 and the hand-held portion 12 facing away from the connecting portion 11 are in contact with the placement table 100, so as to jointly support the electric hot knife and allow the blade 3 to be suspended above the placement table 100. When the support frame 43 cooperates with the second limiting portion, at least part of the support frame 43 is accommodated in the connecting portion 11.

[0041] In this technical solution, when the staff needs to adjust the cutting position of the cutting object, they can rotate the bracket 4 until the support frame 43 of the bracket 4 is limited by the first limit portion. At this time, the bracket 4 cannot continue to rotate, and the support frame 43 and the end of the hand-held portion 12 facing away from the connecting portion 11 are in contact with the placement table 100, thereby jointly supporting the electric hot knife and making its blade 3 suspended above the placement table 100. At this time, the blade faces downward, and the handle 1 is usually close to the staff when placed. The staff can also easily grasp the handle 1 when picking up the knife next time, which helps to prevent the staff from being burned. On the other hand, placing the blade in the air can also prevent burns from other objects placed on the placement table 100.

[0042] Furthermore, when the support frame 43 engages with the second stopper, at least a portion of the support frame 43 is accommodated within the connection portion 11, preventing the support frame 4 from interfering with the cutting operation of the electric knife. Furthermore, compared to embodiments in which the support frame is placed separately on the table 100 and the electric knife is placed on the support frame after use, the present invention pivotally connects the support frame 4 to the side wall 111. This eliminates the need to align the electric knife with the support frame 4 before placing the electric knife, making it more convenient to use.

[0043] Among them, both side walls 111 are provided with matching holes extending along the first direction, and the first rotating shaft 41 and the second rotating shaft 42 are respectively rotated and matched in the corresponding matching holes. The support frame 43 can provide a force to the first rotating shaft 41 and the second rotating shaft 42 to move closer to each other, thereby preventing the first rotating shaft 41 and the second rotating shaft 42 from falling out from the corresponding matching holes, preventing the first rotating shaft 41 and the second rotating shaft 42 from loosening or swinging during rotation, and improving the stability of the bracket 4.

[0044] In some embodiments, the support frame 43 includes a first connecting segment 431, a second connecting segment 432, two support portions 433 spaced apart along the first direction X, and a connecting structure 434 connecting the two support portions 433. The connecting structure 434 can connect the support frame 4 to the upper structures of the two side walls 111, thereby achieving modularization of the support frame 4. One support portion 433 is fixedly connected to the first rotating shaft 41 via the first connecting segment 431, and the other support portion 433 is fixedly connected to the second rotating shaft 42 via the second connecting segment 432. The first connecting segment 431 and the second connecting segment 432 both have tapered sub-segments (e.g., a first tapered sub-segment 4311 and a second tapered sub-segment 4321). The spacing between the two tapered sub-segments in the first direction X gradually decreases as they move away from the support portions 433. The first connecting segment 431 and the second connecting segment 432 are both elastic. Thus, the first connecting segment 431 and the second connecting segment 432 have a force that moves the first rotating shaft 41 and the second rotating shaft 42 closer to each other, and the first connecting segment 431 and the second connecting segment 432 are elastic. During installation, the first connecting segment 431 and the second connecting segment 432 can be manually pulled to move the first rotating shaft 41 and the second rotating shaft 42 away from each other, thereby facilitating the assembly between the first rotating shaft 41 and the second rotating shaft 42 and the corresponding mating holes.

[0045] In other embodiments, the support frame 43 includes a first connecting section 431, a second connecting section 432, two support portions 433 spaced apart along the first direction X, and a connecting structure 434 connecting the two support portions 433. One support portion 433 is fixedly connected to the first rotating shaft 41 via the first connecting section 431, and the other support portion 433 is fixedly connected to the second rotating shaft 42 via the second connecting section 432. Furthermore, the support frame 43 also includes a spring connected between the first connecting section 431 and the second connecting section 432. The spring is in a stretched state, and the contraction force of the spring acts as the force that moves the first rotating shaft 41 and the second rotating shaft 42 closer together.

[0046] Based on any of the above embodiments, the bracket 4 is made of a bent metal wire to obtain the above shape or structure, such as a steel wire or an iron wire. The bracket 4 adopts an integrated structure.

[0047] like Figure 2 and Figure 3As shown, in order to ensure the supporting stability of the bracket 4, the support frame 43 includes two supporting parts 433 arranged at intervals along the first direction X, and the two supporting parts 433 are both facing away from the first rotating shaft 41 and the second rotating shaft 42. The electric hot knife has an assumed reference plane, which is perpendicular to the placement table 100 and parallel to the extension direction of the blade 3. When the support frame 43 is matched with the first limiting part, the rotation axis of the first rotating shaft 41 has a first projection point on the reference plane, and the support part 433 has a second projection point on the reference plane. The connecting line P between the first projection point and the second projection point has an angle α with the extension direction of the blade 3, and the angle α satisfies: 30°~90°.

[0048] Reference Figures 2 to 4 The first limiting portion includes a first limiting plate 1111 protruding from the side wall 111, and the second limiting portion includes a second limiting plate 1112 protruding from the side wall 111. The extension direction of the first limiting plate 1111 and the extension direction of the second limiting plate 1112 intersect, and the intersection coincides with the rotation axis of the first rotating shaft 41. The structure of the limiting structure is simple and easy to implement.

[0049] Alternatively, in other embodiments, a circular arc guide groove with the rotation axis of the first rotating shaft 41 as the center is opened on the side wall 111, and the guide groove has a first terminal end and a second terminal end arranged opposite to each other, and the first terminal end is close to the blade relative to the second terminal end. The first terminal end is used to constitute a first limiting portion, and the second terminal end is used to constitute a second limiting portion. This solution can be implemented by only opening a circular arc guide groove on the side wall of the connecting portion 11.

[0050] For example, the support frame 43 includes a first connecting section 431, a second connecting section 432, two support portions 433 spaced apart along the first direction X, and a connecting structure 434 connecting the two support portions 433. A stopper 1113 is also protruding from the side wall 111. When the first connecting section 431 and the second connecting section 432 respectively abut against the corresponding first limiting plates 1111, the stopper 1113 and the first limiting plates 1111 are respectively located on either side of the support frame 43. The dimension of the stopper 1113 in the first direction X is smaller than the dimension of the first connecting section 431 in the first direction X, and smaller than the dimension of the second connecting section 432 in the first direction X, thereby facilitating the rotation of the support frame 43. In other words, a stop platform 1113 is protruded from both side walls 111 , wherein the dimension of the stop platform 1113 on one side wall 111 in the first direction X is smaller than the dimension of the first connecting section 431 in the first direction X, and the dimension of the stop platform 1113 on the other side wall 111 in the first direction X is smaller than the dimension of the second connecting section 432 in the first direction X. Thus, by ensuring that the height of the stop platform 1113 is lower than the heights of the first connecting section 431 and the second connecting section 432 , the stop platform 1113 can be ensured to have a limiting effect while also facilitating the rotation of the support frame 43 .

[0051] Specifically, the stop platform 1113 is spaced apart from the first limit plate 1111, and the space therebetween constitutes a first limit groove; the stop platform 1113 is spaced apart from the second limit plate 1112, and the space therebetween constitutes a second limit groove; the extension direction of the first edge of the stop platform 1113 facing the first limit plate 1111 is consistent with the extension direction of the first guide plate 1111; the extension direction of the second edge of the stop platform 1113 facing the second limit plate 1112 is consistent with the extension direction of the second guide plate 1112.

[0052] Reference Figures 5 to 7 The handle portion 12 has a transfer end and a support end. The transfer end has two connecting walls 121 spaced apart and opposed in a first direction X. The end of the connecting portion 11, facing away from the blade holder 2, is positioned within the space and rotatably connected to the two connecting walls 121. The rotation axis of the connecting portion 11 is parallel to the first direction X, thereby enabling the angle between the blade 3 and the handle 1 to be adjusted to meet various usage requirements. Typically, the extending direction of the connecting portion 11 coincides with the extending direction of the blade 3.

[0053] Based on the above embodiment, the support frame 43 includes a first connecting section 431, a second connecting section 432, two support parts 433 arranged at intervals along the first direction X, and a connecting structure 434 connected between the two support parts 433, one support part 433 is fixedly connected to the first rotating shaft through the first connecting section 431, and the other support part 433 is fixedly connected to the second rotating shaft through the second connecting section 432, the first connecting section 431 and the second connecting section 432 both have support sub-segments (first support sub-segment 4312 and second support sub-segment 4322), the spacing between the two support sub-segments in the first direction X is equal everywhere, the two connecting walls 121 have support outer wall surfaces arranged back to back, and the two support sub-segments both have outer support surfaces arranged back to back, and the outer support surfaces coincide with the support outer wall surfaces, so that when the above-mentioned electric hot knife is placed on its side, the outer support surface and the support outer wall surface can jointly support the electric hot knife.

[0054] For example, the first connecting segment 431 and the second connecting segment 432 both have tapered sub-segments (a first tapered sub-segment 4311 and a second tapered sub-segment 4321), and the distance between the two tapered sub-segments in the first direction X gradually decreases as they move away from the support portion 433, thereby providing a force to move the first rotating shaft and the second rotating shaft closer to each other.

[0055] The support frame 43 includes two support portions 433 spaced apart along the first direction X, facing away from the first rotation axis 41. The two support portions 433 have a first dimension L1 in the first direction X. The maximum dimension of the handle 1 in the first direction is L2, where L1 = (0.9-1.5) × L2. The first dimension L1 is the maximum dimension of the two support portions 433 in the first direction X, and can also be understood as the maximum dimension of the bracket 4 in the first direction X. For example, in this embodiment, the maximum dimension L2 of the handle 1 in the first direction is the distance between the two supporting outer wall surfaces of the two connecting walls 121, which are arranged opposite to each other, and L1 = L2.

[0056] In addition, please refer to Figure 8 and Figure 9 The support frame 43 includes two support portions 433 spaced apart along the first direction X and facing away from the first rotation axis. The two support portions 433 have a first dimension L1 in the first direction X. The maximum dimension of the handle 1 in the first direction is L2, where L1 = 1.4 × L2. Of course, in other embodiments not shown in the drawings of this application, L1 = 0.9 × L2, L1 = 1.1 × L2, L1 = 1.2 × L2, L1 = 1.3 × L2, L1 = 1.45 × L2, or L1 = 1.5 × L2.

[0057] In some embodiments of the present application, Figure 5As shown, the handle portion 12 has an adapter end and a support end. The end of the connecting portion 11 facing away from the knife holder 2 is rotatably connected to the adapter end. The support end is provided with a hanging portion to facilitate hanging the electric hot knife in a fixed position after use. For example, the hanging portion is a hook, a hanging hole, or a hanging ring.

[0058] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0059] The above is only a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims. In addition, the specification uses specific examples to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core ideas of the present application. The content of this specification should not be understood as limiting the present application.
