Folding mechanism and garden pruning tool

Abstract

The application relates to a folding mechanism and a garden trimming tool. The folding mechanism comprises a first rod, a second rod, a connecting assembly, a wire and an insulating sleeve. The two rods are aluminum rods and are hingedly connected through a connecting piece. The two rods can be relatively rotated to a folding state or an axial alignment state. The wire passes through the two rods in sequence, and the insulating sleeve is sleeved outside the wire. The insulating sleeve is in a hollow cylindrical shape and has a surface roughness of not more than 7 mu m. In the axial alignment state, the two rods are aligned along the axial directions of the two rods and are connected, and the insulating sleeve is accommodated in the two rods. In the folding state, the included angle of the two rods is an acute angle or 0, the insulating sleeve abutting against the inner walls of the two rods is elastically deformed, and part of the insulating sleeve is bent and exposed outside the two rods. When the folding state is converted into the axial alignment state, the insulating sleeve slides along the inner walls of the two rods under the action of a springback force until the deformation is recovered and the exposed part is completely accommodated in the two rods. When the two rods of the folding mechanism are converted into the axial alignment state, the exposed part of the insulating sleeve is easy to slide into the two rods.

Description

Technical Field

[0001] This application relates to the field of garden tool technology, and in particular to folding mechanisms and garden trimming tools. Background Technology

[0002] In urban planning and construction, lawns and green spaces are often planted along roadsides and in parks to beautify the environment and purify the air. After planting, they need to be regularly trimmed using gardening tools to maintain their healthy growth. To expand the trimming range and improve efficiency, gardening tools are mostly designed to be long when in use, but this also means they require a lot of space to store after use. To solve this problem, many gardening tools are now being designed with a folding structure.

[0003] The folding structure includes two hinged rods that can rotate relative to each other. They are axially aligned and connected during use and folded for storage. A portion of the wires passing through the two rods is covered with an insulating sleeve to protect the exposed portion of the wires when the rods are folded. In related technologies, when the two rods are rotated relative to each other to transition from a folded state to an axially aligned state, the exposed portion of the insulating sleeve often protrudes away from the hinge point during rotation, potentially becoming stuck and preventing axial alignment. Consequently, the insulating sleeve cannot be smoothly retracted into the rods, requiring manual adjustment. Summary of the Invention

[0004] Therefore, it is necessary to provide a folding mechanism and garden trimming tool. When the two rods are switched from the folded state to the axially aligned state, the insulating sleeve is not easy to get stuck, and the exposed part can smoothly slide into the two rods without manual adjustment, making the operation more convenient.

[0005] A folding mechanism for use in garden pruning tools, the folding mechanism comprising:

[0006] First member;

[0007] The second member; and

[0008] The connecting assembly includes a connector, a wire, and an insulating sleeve. Both the first and second rods are aluminum rods and are hinged together by the connector, allowing them to rotate relative to each other to a folded state or an axially aligned state. The wire passes sequentially through the first and second rods. The insulating sleeve is a hollow cylinder and is fitted over a portion of the wire. The outer surface roughness of the insulating sleeve is no greater than 7 μm.

[0009] In the axially aligned state, the first rod and the second rod are aligned and connected along their own axial direction, and the insulating sleeve is housed inside the first rod and the second rod; in the folded state, the included angle between the first rod and the second rod is an acute angle or 0, and the insulating sleeve that abuts against the inner wall of the first rod and the second rod is in an elastically deformed state, and a portion of it is bent and exposed outside the first rod and the second rod.

[0010] During the transition from the folded state to the axially aligned state, the insulating sleeve slides along the inner walls of the first and second rods under its own rebound force until the deformation is restored and the exposed portion is completely retracted into the first and second rods.

[0011] In some embodiments, the outer surface roughness of the insulating sleeve is not greater than 6.4 μm.

[0012] In some embodiments, in the axially aligned state, the hinge point of the first rod and the second rod is located on one radial side of each other. When the first rod and the second rod rotate relative to each other based on the hinge point, a rotation arc is formed on the opposite side of the hinge point on their inner walls. During the transition from the folded state to the axially aligned state, the insulating sleeve does not extend beyond the outside of the rotation arc.

[0013] In some embodiments, the radius of rotation of the rotating arc is r, where 30mm ≤ r ≤ 60mm.

[0014] In some embodiments, r is 42 mm.

[0015] In some embodiments, the wall thickness of the insulating sleeve is a, where 0.5mm ≤ a ≤ 2mm.

[0016] In some embodiments, a is 1 mm.

[0017] In some embodiments, the total length of the insulating sleeve is s, where 160mm ≤ s ≤ 300mm.

[0018] In some embodiments, the Shore hardness of the insulating sleeve is greater than 40.

[0019] In some embodiments, the insulating sleeve is made of polyethylene.

[0020] In some embodiments, the connecting assembly includes a locking member, the connecting member includes a first connecting portion and a second connecting portion, the first connecting portion is disposed at the end of the first rod, the second connecting portion is disposed at the end of the second rod, the first connecting portion and the second connecting portion are hinged at one end along their own radial direction, and the other end can be locked by the locking member in the axial alignment state.

[0021] In some embodiments, the connection assembly includes binding members, and the binding members at both ends of the insulating sleeve are provided to bind the outside of the conductor.

[0022] A garden trimming tool, the garden trimming tool including the above-described folding mechanism.

[0023] The aforementioned folding mechanism and garden trimming tool are hinged together by a connector, allowing the first and second rods to rotate relative to each other to either a folded state or an axially aligned state. In the axially aligned state, the garden trimming tool can be used normally; in the folded state, the included angle between the first and second rods is acute or 0°, facilitating the storage and folding of the tool. An insulating sleeve is fitted over a portion of the conductor, protecting the exposed portion of the conductor outside the first and second rods in the folded state. In the folded state, the outer wall of one end of the insulating sleeve abuts against the inner wall of the first rod, and the outer wall of the other end abuts against the inner wall of the second rod, causing bending deformation of the portion of the insulating sleeve exposed outside the first and second rods. Since the outer surface roughness of the insulating sleeve is no greater than 7μm, the friction between the outer wall of the insulating sleeve and the inner walls of the two rods will not be excessive during the relative rotation of the two rods from a folded state to an axially aligned state. This reduces the resistance of the two rods to the deformation recovery process of the insulating sleeve, allowing the two ends of the insulating sleeve to slide smoothly along the inner walls of the first and second rods. This gradually reduces the curvature of the portion of the insulating sleeve exposed on the two rods, causing it to gradually straighten and eventually retract into the first and second rods. In summary, by limiting the outer surface roughness of the insulating sleeve, the friction between the outer wall of the insulating sleeve and the inner walls of the two rods can be reduced during the transition from a folded state to an axially aligned state. This prevents the insulating sleeve from getting stuck due to excessive friction, allowing the exposed portion to slide smoothly into the two rods without manual adjustment, making operation more convenient.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional 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, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0038] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0041] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0042] See Figure 1 This application provides a folding mechanism for garden pruning tools, as described in one embodiment. The folding mechanism includes a first member 100, a second member 200, and a connecting assembly 500. See also... Figures 2 to 5The connecting assembly 500 includes a connector 510, a wire 520, and an insulating sleeve 530. The first rod 100 and the second rod 200 are both aluminum rods and are hinged together by the connector 510, allowing the first rod 100 and the second rod 200 to rotate relative to each other to a folded state or an axially aligned state. The wire 520 passes sequentially through the first rod 100 and the second rod 200. The insulating sleeve 530 is a hollow cylinder and is fitted over a portion of the wire 520. The outer surface roughness of the insulating sleeve 530 is no greater than 7 μm. In the axially aligned state, the first rod 100 and the second rod 200 are aligned and connected along their own axes, with the insulating sleeve 530 housed within them. In the folded state, the included angle between the first rod 100 and the second rod 200 is an acute angle or 0°. The first rod 100 can rotate relative to the second rod 200 from the axially aligned state to the folded state. When the first rod 100 and the second rod 200 are in a folded state, the insulating sleeve 530, which abuts against the inner walls of the first rod 100 and the second rod 200, is in an elastically deformed state, and a portion of it is bent and exposed outside the first rod 100 and the second rod 200. During the transition from the folded state to the axially aligned state, the insulating sleeve 530 slides along the inner walls of the first rod 100 and the second rod 200 under its own elastic force until the deformation returns to normal and the exposed portion 531 is completely retracted into the first rod 100 and the second rod 200.

[0043] In the aforementioned folding mechanism, the first member 100 and the second member 200 are hinged together by a connector 510, allowing the first member 100 and the second member 200 to rotate relative to each other to a folded state or an axially aligned state. In the axially aligned state (e.g....), Figure 1 As shown), garden trimming tools can be used normally; in the folded state (such as... Figure 3As shown, the included angle between the first rod 100 and the second rod 200 is an acute angle or 0°, which facilitates the storage of garden trimming tools. An insulating sleeve 530 is fitted over a portion of the conductor 520, thus protecting the exposed portion of the conductor 520 outside the first rod 100 and the second rod 200 in the folded state. In the folded state, the outer wall of one end of the insulating sleeve 530 abuts against the inner wall of the first rod 100, and the outer wall of the other end abuts against the inner wall of the second rod 200, causing the exposed portion of the insulating sleeve 530 outside the first rod 100 and the second rod 200 to bend and deform. Since the outer surface roughness of the insulating sleeve 530 is no greater than 7μm, during the process of the two rods rotating relative to each other and changing from a folded state to an axially aligned state, the friction between the outer wall of the insulating sleeve 530 and the inner wall of the two rods will not be too large. This reduces the resistance of the two rods to the deformation recovery process of the insulating sleeve 530, allowing the two ends of the insulating sleeve 530 to slide smoothly along the inner wall of the first rod 100 and the second rod 200. This gradually reduces the degree of bending of the part of the insulating sleeve 530 exposed on the two rods (exposed part 531), causing it to gradually straighten and gradually retract into the first rod 100 and the second rod 200. In summary, by limiting the surface roughness of the insulating sleeve 530, the friction between the outer wall of the insulating sleeve 530 and the inner walls of the two rods can be reduced during the transition from the folded state to the axial alignment state. This makes it less likely for the insulating sleeve 530 to get stuck due to excessive friction, and the exposed part 531 can smoothly slide into the two rods without manual adjustment, making the operation more convenient.

[0044] In some embodiments, the first rod 100 is used to connect to the handle assembly 300 of the garden trimming tool; the second rod 200 is used to connect to the trimming assembly 400 of the garden trimming tool.

[0045] In this garden trimming tool, the handle assembly 300 is used for the operator to hold and contains components such as a motor and battery pack. The trimming assembly 400 includes components such as blades and is used for trimming lawns, green belts, etc. A wire 520 passes sequentially through the first rod 100 and the second rod 200, electrically connecting the trimming assembly 400 and the motor and other components in the handle assembly 300 to achieve power supply and control. In this embodiment, "axial alignment" means that the central axes of the first rod 100 and the second rod 200 coincide, and their ends are completely aligned. In this embodiment, "folded state" can mean either that the central axes of the first rod 100 and the second rod 200 are parallel, and the second rod 200 is located on the radial side of the first rod 100, allowing them to be stacked parallel to each other, in which case the included angle between the first rod 100 and the second rod 200 is 0°. Alternatively, the first rod 100 and the second rod 200 are not parallel, forming an acute angle, which also facilitates storage.

[0046] Since both the first rod 100 and the second rod 200 are made of aluminum tubing, they are lightweight and easy to carry and use.

[0047] See Figures 2 to 5 In some embodiments, the outer surface roughness of the insulating sleeve 530 is no greater than 6.4 μm.

[0048] By further restricting the roughness of the outer surface of the insulating sleeve 530, making its outer surface as smooth as possible, the friction between the outer wall of the insulating sleeve 530 and the inner wall of the two rods will be smaller during the process of the two rods rotating relative to each other to change from a folded state to an axially aligned state. This will further reduce the resistance of the two rods to the deformation recovery process of the insulating sleeve 530, allowing the two ends of the insulating sleeve 530 to slide more smoothly along the inner walls of the first rod 100 and the second rod 200, and gradually retract into the first rod 100 and the second rod 200.

[0049] See Figures 2 to 5 In some embodiments, in the axially aligned state, the hinge point 513 of the first rod 100 and the second rod 200 is located on one radial side of the two. When the first rod 100 and the second rod 200 rotate relative to each other based on the hinge point 513, a rotation arc 600 is constructed on the opposite side of the hinge point 513 on their inner walls. During the transition from the folded state to the axially aligned state, the insulating sleeve 530 does not extend beyond the outside of the rotation arc 600.

[0050] Specifically, the hinge point 513 of the first rod 100 and the second rod 200 is located on the connector 510. When the first rod 100 and the second rod 200 rotate relative to each other based on the hinge point 513, the distance between the position on the inner wall of the two rods opposite the hinge point 513 and the hinge point 513 is the radius of rotation. A rotation arc 600 is constructed on the inner wall of the two rods opposite the hinge point 513. During the transition from the folded state to the axially aligned state, the exposed portion 531 of the insulating sleeve 530 does not extend beyond the outside of the rotation arc 600, that is, when projected in the vertical plane, the outer edge projection of the exposed portion 531 does not extend beyond the projection of the rotation arc 600. When the above conditions are met, it indicates that the outward protrusion of the exposed portion 531 is not significant, thus making it easier to recover its deformation and more easily retract into the first rod 100 and the second rod 200.

[0051] See Figures 2 to 5 In some embodiments, the radius of rotation of the rotating arc 600 is r, where 30mm ≤ r ≤ 60mm.

[0052] Understandably, when the rotation radius r is too small, the exposed portion 531 of the insulating sleeve 530 will bend more, potentially getting stuck and difficult to retract into the first member 100 and the second member 200. When the rotation radius r is too large, the overall size of the connecting assembly 500 needs to be larger, which is not conducive to the miniaturization and storage of the overall structure. When the rotation radius meets the above-mentioned size range, both aspects can be balanced, that is, the exposed portion 531 can be smoothly retracted into the first member 100 and the second member 200, and the overall size of the structure will not be too large.

[0053] See Figures 2 to 5 In some embodiments, r is 42 mm. When the rotation radius is taken as described above, the effects of the two aspects are optimally balanced.

[0054] See Figures 2 to 5 In some embodiments, the wall thickness of the insulating sleeve 530 is a, where 0.5mm ≤ a ≤ 2mm.

[0055] Understandably, when the wall thickness of the insulating sleeve 530 is too small, it is not conducive to threading the wire 520 through it, and the overall structure is too soft. During the transition from the folded state to the axially aligned state, the exposed part 531 is prone to getting stuck and cannot be smoothly retracted into the two rods. When the wall thickness of the insulating sleeve 530 is too large, the cost is high, and when the two rods are folded, the exposed part 531 is difficult to bend and deform, which may hinder folding. When the wall thickness of the insulating sleeve 530 meets the above-mentioned size range, both aspects can be taken into account, that is, it is easy for the exposed part 531 to be smoothly retracted into the two rods, while minimizing cost and folding operation difficulty.

[0056] See Figures 2 to 5 In some embodiments, a is 1 mm. When the wall thickness of the insulating sleeve 530 is taken as the above value, the effects of the two aspects are in the best balance.

[0057] See Figures 2 to 5 In some embodiments, the total length of the insulating sleeve 530 is s, where 160mm ≤ s ≤ 300mm.

[0058] Understandably, if the total length of the insulating sleeve 530 is too small, it may not be able to completely cover the portion of the conductor 520 exposed outside the two poles when folded, thus providing limited protection for the conductor 520. If the total length of the insulating sleeve 530 is too large, it will result in waste and increase costs. When the total length of the insulating sleeve 530 meets the above-mentioned size range, both aspects can be balanced, that is, in the folded state, the portion of the conductor 520 exposed outside the two poles can be completely covered, providing adequate protection, while the cost is not too high.

[0059] See Figures 2 to 5In some embodiments, the Shore hardness of the insulating sleeve 530 is greater than 40.

[0060] Understandably, when the rigidity of the insulating sleeve 530 is too low, it becomes too soft overall. During the transition from the folded state to the axially aligned state, the exposed portion 531 is prone to getting stuck and cannot be smoothly retracted into the two rods. By imposing the aforementioned restrictions on its rigidity, this can be mitigated as much as possible, allowing the exposed portion 531 to be retracted into the two rods more smoothly.

[0061] See Figures 2 to 5 In some embodiments, the insulating sleeve 530 is made of polyethylene. This material is suitable in terms of hardness, elasticity, and cost.

[0062] See Figures 2 to 5 In some embodiments, the connecting assembly 500 includes a locking member, and the connecting member 510 includes a first connecting portion 511 and a second connecting portion 512. The first connecting portion 511 is disposed at the end of the first rod 100, and the second connecting portion 512 is disposed at the end of the second rod 200. The first connecting portion 511 and the second connecting portion 512 are hinged at one end along their own radial direction, and the other end can be locked by the locking member in an axially aligned state.

[0063] Specifically, the first connecting part 511 can be integrally formed with the first rod 100, and the second connecting part 512 can be integrally formed with the second rod 200. Figure 4 From this perspective, the right end of the first connecting part 511 and the second connecting part 512 is the hinge end, and the left end is the rotating end. When the first connecting part 511 and the second connecting part 512 rotate relative to each other until they are closed, they can be locked together by fasteners such as screws, thereby fixing the relative position of the first rod 100 and the second rod 200. When it is necessary to fold the first rod 100 and the second rod 200, simply loosen the screws to release the locking of the first connecting part 511 and the second connecting part 512, allowing them to rotate relative to each other until the first rod 100 and the second rod 200 are folded.

[0064] See Figures 2 to 5 In some embodiments, the connecting component 500 includes a binding member 540, and both ends of the insulating sleeve 530 are provided with binding members 540 that are bound to the outside of the wire 520.

[0065] Specifically, the binding component 540 can be a cable tie or a plastic clamp, etc. When the binding component 540 is set at both ends of the outer insulating sleeve 530 of the conductor 520, the position of the insulating sleeve 530 can be restricted so that it does not slide freely along the conductor 520 and can be kept in an appropriate position so as to ensure that it can wrap the exposed conductor 520 in the folded state and play a protective role.

[0066] See Figure 1One embodiment of this application provides a garden trimming tool that includes the folding mechanism found in any of the foregoing embodiments.

[0067] In some embodiments, the garden trimming tool further includes a handle assembly 300 and a trimming assembly 400, with a first member 100 connected to the handle assembly 300 and a second member 200 connected to the trimming assembly 400.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
