Description

Technical Field

[0001] This utility model belongs to the field of chopping tools technology, and more specifically relates to a foldable axe. Background Technology

[0002] An axe is a metal chopping tool, generally used for felling trees, splitting firewood, and cutting timber. A typical axe consists of a handle and a blade connected to the handle. The blade is made of metal and has an axe edge fixedly connected to the handle; the axe edge is parallel to the handle. When using it, gripping the handle allows you to operate the axe edge to chop objects, making the chopping operation convenient.

[0003] However, existing axes still have shortcomings. The blade and handle of existing axes are fixedly connected. When chopping is not needed, the blade cannot be folded relative to the handle, which makes the whole axe larger, taking up storage space and making it inconvenient to carry and store. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a foldable axe.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a foldable axe, including a handle and an axe blade connected to the handle. The handle includes a handle body, a first connecting rod, a second connecting rod, and a rotating blade. The rear end of the first connecting rod is rotatably connected to the handle body, and the front end of the first connecting rod is rotatably connected to the axe blade. The axe blade can rotate open and fold relative to the first connecting rod. The rear end of the second connecting rod is connected to the handle body, and the front end of the second connecting rod is rotatably connected to the rotating blade. The rotating blade can rotate open and fold relative to the second connecting rod. The axe blade is rotatably connected to the rotating blade through a first rotating shaft. Rotating the axe blade to open will simultaneously drive the rotating blade to rotate open, and rotating the axe blade to fold will simultaneously drive the rotating blade to rotate fold. The handle body is provided with a locking mechanism to prevent the first connecting rod from rotating when the axe blade is open.

[0006] In the above solution, the rear end of the first connecting rod is rotatably connected to the handle, and the front end of the first connecting rod is rotatably connected to the axe blade. The axe blade is rotatably connected to the rotating plate via a first pivot. Thus, when the axe blade is rotated, the first connecting rod and the rotating plate also rotate, creating a linkage structure between the axe blade, the first connecting rod, and the rotating plate. In use, the axe blade can be rotated to open, allowing the handle to be gripped and the axe blade used for chopping. When the axe blade is open, a locking mechanism prevents the first connecting rod from rotating. With the first connecting rod unable to rotate, the axe blade also cannot rotate, thus locking the axe blade in the open state and ensuring its structural stability, making chopping safer and more convenient. When chopping is not needed, the locking mechanism can be released from the first connecting rod, allowing the axe blade to rotate and fold relative to the first connecting rod. Simultaneously, the rotating plate will also rotate and fold relative to the second connecting rod. The folded axe head becomes narrower, reducing its space requirements and making it easier to carry and store. Furthermore, the blade of the folded axe is positioned opposite the front end of the handle, which blocks the blade, making it less likely to be accidentally injured by the blade and safer to carry. Furthermore, the aforementioned locking mechanism is a spring plate located inside the handle body. When the axe blade is rotated to the open state, and without external force, the free end of the spring plate automatically deforms to the right through its own elastic force and abuts against the rear end face of the first connecting rod. At this time, the first connecting rod cannot rotate under the abutment of the free end of the spring plate, thus locking the axe blade in the open state. Pressing the free end of the spring plate to return it to the left and disengage it from the rear end face of the first connecting rod releases the rotation restriction on the first connecting rod, thereby allowing the axe blade to be rotated and folded.

[0007] Furthermore, the aforementioned handle includes a left handle plate and a right handle plate arranged opposite to each other. An outer rotating cylinder is provided on the inner side of the front end of the left handle plate, and an inner rotating cylinder is provided on the inner side of the front end of the right handle plate. The inner rotating cylinder is placed inside the outer rotating cylinder. The rear end of the first connecting rod is fitted onto the outer side of the outer rotating cylinder at the position between the two handle plates through a first ring, so that the first connecting rod can rotate around the outer rotating cylinder through the first ring to realize the structural function of rotating connection between the first connecting rod and the handle. The aforementioned spring plate is located on the inner side of the left handle plate.

[0008] Furthermore, the rear end of the aforementioned second connecting rod is fitted onto the outer side of the outer rotating cylinder via a second sleeve ring, corresponding to the position between the first sleeve ring and the right handle plate. This facilitates the assembly and disassembly of the second connecting rod. The side wall of the aforementioned first sleeve ring has a guide groove, and the inner side of the left handle plate has a connecting post. The right end of the connecting post passes through the guide groove and the side wall of the second sleeve ring and connects to the inner side of the right handle plate. With the obstruction of the connecting post, the second sleeve ring of the second connecting rod cannot rotate around the outer rotating cylinder, while the guide groove provides the necessary space for the rotation of the first sleeve ring of the first connecting rod, thus not affecting the rotation, opening, and folding of the axe blade.

[0009] Furthermore, a washer is fitted on the outer side of the aforementioned outer rotating cylinder between the first and second rings to reduce friction between the first and second rings.

[0010] Furthermore, the rear ends of the left and right handle plates are connected by a connecting assembly, which includes a female pin and a male pin. The female pin passes through the rear ends of the left and right handle plates and connects with the male pin to facilitate the assembly and disassembly of the left and right handle plates.

[0011] Furthermore, the end of the aforementioned rotating blade furthest from the hinge point with the second connecting rod is a pointed structure. When the axe blade is rotated to the open state, the pointed structure of the rotating blade can be used to pry, penetrate, or strike objects, thereby increasing the axe's functionality and making it more versatile.

[0012] Furthermore, the front end of the first connecting rod is rotatably connected to the end of the axe blade via the second rotating shaft, so that the axe blade can rotate and open and fold relative to the first connecting rod around the second rotating shaft. The front end of the second connecting rod is rotatably connected to the end of the rotating piece via the third rotating shaft, so that the rotating piece can rotate and open and fold relative to the second connecting rod around the third rotating shaft. The axes of the first, second, and third rotating shafts are connected to form a triangular structure, thereby realizing that the axe blade, the rotating piece, and the first connecting rod are interconnected.

[0013] Furthermore, the axe blade is provided with a first abutment portion near the end that is hinged to the first connecting rod, and a second abutment portion is provided at the front end of the first connecting rod. When the axe blade is rotated to the open state, the first abutment portion of the axe blade abuts against the second abutment portion of the first connecting rod. At this time, the axe blade cannot continue to rotate in the opening direction due to the obstruction of the second abutment portion, so as to avoid the axe blade rotating excessively in the opening direction and improve the opening stability of the axe blade.

[0014] Furthermore, the first connecting rod has a clearance groove on its side wall. When the axe blade is rotated to the folded state, the axe blade is placed in the clearance groove. This allows the axe blade to be made larger, making it easier to chop objects. At the same time, the axe blade side wall abuts against the first connecting rod side wall. At this time, the axe blade cannot continue to rotate in the folding direction due to the obstruction of the first connecting rod side wall, so as to avoid the axe blade rotating too much in the folding direction and improve the folding stability of the axe blade.

[0015] When not in use, this foldable axe can have its blade and rotating blade folded up, reducing the axe's width and space requirements for easy carrying and storage. The folded blade's edge is positioned opposite the front of the handle and partially within a clearance groove, preventing accidental injury and enhancing safety. Furthermore, in the open state, the first connecting rod is prevented from rotating due to the resistance of the spring-loaded end, locking the axe in the open position for convenient and safe chopping. Additionally, the rotating blade's tip can be operated for prying, piercing, and striking objects, expanding the axe's versatility. Attached Figure Description

It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "long," and "short" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0023] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings: Example 1 like Figure 1-4 As shown, this embodiment provides a foldable axe, including a handle and an axe blade 2 connected to the handle. The handle includes a handle body 11, a first connecting rod 12, a second connecting rod 13, and a rotating plate 14. The rear end of the first connecting rod 12 is rotatably connected to the handle body 11, and the front end of the first connecting rod 12 is rotatably connected to the upper end of the axe blade 2. The axe blade 2 can rotate open and fold relative to the first connecting rod 12. The rear end of the second connecting rod 13 is connected to the handle body 11, and the front end of the second connecting rod 13 is rotatably connected to the lower end of the rotating plate 14. The rotating plate 14 can rotate open and fold relative to the second connecting rod 13. The axe blade 2 is rotatably connected to the rotating plate 14 through a first rotating shaft 31. Rotating the axe blade 2 to open will simultaneously drive the rotating plate 14 to rotate open, and rotating the axe blade 2 to fold will simultaneously drive the rotating plate 14 to rotate fold. The handle body 11 is provided with a locking mechanism to prevent the first connecting rod 12 from rotating when the axe blade 2 is open.

[0024] In the above scheme, by rotatably connecting the rear end of the first connecting rod 12 to the handle 11 and rotatably connecting the front end of the first connecting rod 12 to the axe blade 2, and rotatably connecting the axe blade 2 to the rotating plate 14 through the first rotating shaft 31, the first connecting rod 12 and the rotating plate 14 will also rotate when the axe blade 2 is rotated, so that the axe blade 2, the first connecting rod 12 and the rotating plate will achieve a linkage structure, thereby causing the rotating plate 14 to rotate open and fold at the same time as the axe blade 2 rotates open and folds.

[0025] In this embodiment, when the axe is used, the axe blade 2 can be pushed forward to rotate to the open state, such as... Figure 2 As shown, one can hold the handle and operate the axe blade 2 to chop objects. When the axe blade 2 is open and no external force is applied, the locking mechanism prevents the first link 12 from rotating. With the first link 12 unable to rotate, the axe blade 2 also cannot rotate, thus locking the axe blade 2 in the open state and ensuring its structural stability, making chopping safer and more convenient. When chopping is no longer needed, the locking mechanism can be released from the first link 12, allowing the axe blade 2 to rotate backward to a folded state. Simultaneously, the rotating piece 14 will also rotate relative to the second link 13 to a folded state. Figure 4 As shown, the width of the folded axe head decreases, thus reducing its space requirements and making it easier to carry and store. Furthermore, the axe blade of the folded axe piece 2 is positioned opposite the front end of the handle 11, causing the axe blade of the axe piece 2 to be blocked by the handle 11. This reduces the risk of accidental injury from the axe blade and makes carrying the axe piece safer. Specifically, such as Figure 1 , 3As shown, the locking mechanism is a spring piece 4 located inside the handle 11. The rear end of the spring piece 4 is fixedly connected to the handle 11, and the front end of the spring piece 4 is a free end. When the axe blade 2 is rotated to the open state, and without external force, the free end of the spring piece 4 will automatically deform to the right and abut against the rear end face of the first connecting rod 12 due to its own elastic force. At this time, the first connecting rod 12 cannot rotate under the abutment of the free end of the spring piece 4, thus locking the axe blade 2 in the open state. Pressing the free end of the spring piece 4 to reset it to the left and disengage it from the rear end face of the first connecting rod 12 will release the rotation restriction on the first connecting rod 12, thus allowing the axe blade 2 to be rotated and folded.

[0026] Example 2 This embodiment is a further improvement on the foldable axe structure of Embodiment 1. The improvement lies in that, as... Figure 1 As shown, the aforementioned handle 11 includes a left handle plate 111 and a right handle plate 112 arranged opposite to each other. An outer rotating cylinder 113 is provided on the inner side of the front end of the left handle plate 111, and an inner rotating cylinder 114 is provided on the inner side of the front end of the right handle plate 112. The inner rotating cylinder 114 is placed inside the outer rotating cylinder 113. The rear end of the first connecting rod 12 is fitted onto the outer side of the outer rotating cylinder 113 via a first collar 121, corresponding to the position between the left handle plate 111 and the right handle plate 112. This allows the first connecting rod 12 to rotate around the outer rotating cylinder 113 via the first collar 121, thus realizing the structural function of rotatably connecting the first connecting rod 12 to the handle 11. The rear end of the aforementioned spring plate 4 is fixedly disposed on the inner side of the left handle plate 111. The rear end face of the first collar 121 is flat, as shown... Figure 3 As shown, when the axe blade 2 is in the open state, the free end of the spring piece 4 abuts against the rear end plane of the first ring 121 of the first connecting rod 12. By abutting the free end of the spring piece 4 against the plane, the first connecting rod 12 can be more stably restricted from rotating.

[0027] For example Figure 1 As shown, the rear end of the second connecting rod 13 is fitted onto the outer side of the outer rotating cylinder 114 via a second collar 131, corresponding to the position between the first collar 121 and the right handle plate 112. This facilitates the assembly and disassembly of the second connecting rod 13. The side wall of the first collar 121 is provided with a guide groove 122, and the inner side of the left handle plate 111 is provided with a connecting post 5. The right end of the connecting post 5 passes through the guide groove 122 and the side wall of the second collar 131 and connects to the inner side of the right handle plate 112. With the obstruction of the connecting post 5, the second collar 131 of the second connecting rod 13 cannot rotate around the outer rotating cylinder 114, while the guide groove 122 will provide the necessary space for the rotation of the first collar 121 of the first connecting rod 12, so as to ensure that the first collar 121 can rotate normally around the outer rotating cylinder 114, thereby not affecting the rotation, opening and folding of the axe plate 2.

[0028] Furthermore, a washer 6 is fitted between the first collar 121 and the second collar 131 on the outer side of the aforementioned outer rotating cylinder 114 to reduce friction between them. The rear ends of the aforementioned left handle plate 111 and right handle plate 112 are connected by a connecting assembly, which includes a female pin 71 and a male pin 72. The female pin 71 passes through the rear ends of the left handle plate 111 and the right handle plate 112 and connects to the male pin 72 to facilitate the assembly and disassembly of the left handle plate 111 and the right handle plate 112.

[0029] Example 3 This embodiment is a further improvement on the foldable axe structure of Embodiment 2. The improvement lies in that, as Figure 1 , 2 As shown, the upper end of the rotating blade 14 is a pointed structure 141. When the axe blade 2 is rotated to the open state, the pointed structure 141 of the rotating blade 14 extends out of the upper side of the axe blade 2, while the axe blade of the axe blade 2 is located on the lower side of the axe blade 2. At this time, the pointed structure 141 of the rotating blade 14 can be used to pry, penetrate, and strike objects, thereby increasing the function of the axe and making its uses more diverse.

[0030] like Figure 2 , 4 As shown, the front end of the first connecting rod 12 is rotatably connected to the upper end of the axe blade 2 via the second rotating shaft 32, so that the axe blade 2 can rotate and open and fold relative to the first connecting rod 12 around the second rotating shaft 32. The front end of the second connecting rod 13 is rotatably connected to the lower end of the rotating piece 14 via the third rotating shaft 33, so that the rotating piece 14 can rotate and open and fold relative to the second connecting rod 12 around the third rotating shaft 33. The axes of the first rotating shaft 31, the second rotating shaft 32, and the third rotating shaft 33 are connected to form a triangular structure, thereby realizing that the axe blade 2, the rotating piece 14, and the first connecting rod 12 are interconnected.

[0031] As an improvement to this embodiment, such as Figure 1 , 2 As shown in Figure 5, the axe blade 2 is provided with a first abutting part 21 at its upper end and a second abutting part 123 at the front end of the first connecting rod 12. When the axe blade 2 is rotated to the open state, the first abutting part 21 of the axe blade 2 abuts against the second abutting part 123 of the first connecting rod 12. At this time, the axe blade 2 cannot continue to rotate in the opening direction due to the obstruction of the second abutting part 123, so as to avoid the axe blade 2 rotating excessively in the opening direction and improve the opening stability of the axe blade 2.

[0032] like Figure 3 , 4As shown, the right side wall of the first connecting rod 12 is provided with a relief groove 124. When the axe blade 2 is rotated to the folded state, part of the axe blade 2 is placed in the relief groove 124. This allows the axe blade part of the axe blade 2 to be made larger, making it easier to chop objects. At the same time, the right side wall of the axe blade 2 abuts against the lower side wall of the first connecting rod 12. At this time, the axe blade 2 cannot continue to rotate in the folding direction due to the obstruction of the lower side wall of the first connecting rod 12, so as to avoid the axe blade 2 from rotating excessively in the folding direction and improve the folding stability of the axe blade 2. Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
