Description

Technical Field

[0001] This utility model relates to the field of agricultural tools, specifically to a folding rake. Background Technology

[0002] A rake, a common agricultural tool, is used for leveling land, clearing weeds, or collecting debris. Traditional rakes typically have long, fixed handles and heads, resulting in a large overall length that is inconvenient for transportation and storage. To address this issue, some foldable rakes have appeared on the market, with the common folding method involving a simple hinge that rotates the rake head relative to the handle. However, this type of folding often suffers from structural instability, still occupying a significant amount of space after folding, or having an irregular shape that is difficult to bundle. Therefore, it is necessary to provide a foldable rake with a more compact structure, a more regular shape, and easier operation after folding. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a folding rake that, through a unique linkage drive mechanism, can smoothly fold the rake head to a state parallel to the handle, greatly reducing the storage volume, and is structurally stable and easy to operate.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A folding rake, including a handle, characterized in that it further includes a connecting frame, a first locking mechanism, a second locking mechanism, and at least two connecting bars;

[0006] One end of the connecting frame is movably connected to one end of the handle through a first movable connection point, and the other end of the connecting frame is fixedly provided with rake teeth;

[0007] The connecting frame is provided with at least two connecting holes spaced apart along its length;

[0008] The first locking mechanism is fixedly sleeved on the handle and located between the first movable connection point and the handle grip portion;

[0009] The second locking mechanism is slidably fitted onto the handle and is located between the first locking mechanism and the handle grip portion;

[0010] One of the connecting bars has its two ends movably connected to the first locking mechanism and one of the connecting holes, respectively; the other connecting bar has its two ends movably connected to the second locking mechanism and the other connecting hole, respectively.

[0011] By sliding the second locking mechanism along the handle axis to change its distance from the first locking mechanism, the two connecting bars work together to drive the connecting frame from an unfolded position perpendicular to the handle to a folded-back position approximately parallel to the handle.

[0012] Preferably, the first active connection point is a pivot shaft.

[0013] Preferably, the first locking mechanism and / or the second locking mechanism are clamp structures and are fastened by bolts.

[0014] Preferably, the first locking mechanism and the second locking mechanism are respectively provided with mutually cooperating locking structures on their opposite end faces. When the second locking mechanism slides to the predetermined position where the connecting frame is unfolded, the locking structures engage with each other to lock the unfolded state of the connecting frame.

[0015] Further preferably, the locking structure includes at least one protrusion disposed on the first locking mechanism and a movable lock disposed on the second locking mechanism; the movable lock is movably disposed on the second locking mechanism and is provided with a limiting hole adapted to the protrusion; when the movable lock moves to the locking position, the protrusion is engaged in the limiting hole.

[0016] Preferably, the grip portion of the handle is covered with an anti-slip sleeve.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model, through the cooperation of double connecting strips and sliding locking mechanism, can stably fold the connecting frame and rake teeth from the working state to a compact state parallel to the handle, greatly reducing the overall length and storage space, making it easy to carry and store.

[0019] 2. This utility model can complete the folding or unfolding action by simply sliding the second locking mechanism up and down, and the locking structure ensures the firmness in the working state, thereby improving the user's efficiency.

[0020] 3. This utility model allows users to fine-tune the connection points of the connecting strips by setting multiple connection holes on the connecting frame, thereby changing the unfolding angle or the tightness after folding within a certain range, thus improving the applicability of the product.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "both sides", "horizontal", "center", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying 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, they should not be construed as limitations on this utility model.

[0028] Furthermore, in the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0029] like Figures 1 to 3 As shown, the folding rake provided by this utility model mainly includes a handle 1, a connecting frame 2, a first locking mechanism 4, a second locking mechanism 5, and two connecting strips 6.

[0030] The handle 1 is a long rod-shaped structure, and its gripping part is covered with an anti-slip sleeve 9 to increase comfort and safety during use. One end of the connecting frame 2 is movably connected to the top of the handle 1 via a pivot shaft (i.e., the first movable connection point), allowing the connecting frame 2 to move around this point in a certain plane. The other end of the connecting frame 2 is fixedly equipped with rake teeth 3. Multiple connecting holes 21 are spaced apart along the length of the rod of the connecting frame 2.

[0031] The first locking mechanism 4 is a clamp structure, which is fastened by bolts 8 and fixedly installed on the handle 1, with its installation position between the aforementioned pivot shaft and the grip part of the handle 1. The second locking mechanism 5 is also a clamp structure, but it is slidably fitted onto the handle 1, and its position is below the first locking mechanism 4 (i.e., closer to the handle grip part). Two rigid connecting bars 6 are used; the upper end of one is movably connected to the first locking mechanism 4 via a pin, and the lower end is movably connected to a connecting hole 21 on the connecting frame 2 near the rake teeth 3; the upper end of the other connecting bar 6 is movably connected to the second locking mechanism 5 via a pin, and the lower end is movably connected to a connecting hole 21 on the connecting frame 2 near the pivot shaft. All movable connections are pivot connections, allowing the connecting bars 6 to rotate freely during movement.

[0032] like Figure 3 As shown, to ensure stable operation, a protrusion 7 is provided on the end face of the first locking mechanism 4 facing the second locking mechanism 5. A movable lock 10 is provided at a corresponding position on the second locking mechanism 5. This movable lock 10 can be a sliding locking plate with a limiting hole 101. When the second locking mechanism 5 slides upwards to the fully extended position of the connecting frame 2, the protrusion 7 aligns precisely with the limiting hole 101, pushing the movable lock 10 to the locking position, causing the protrusion 7 to engage within the limiting hole 101. This prevents the second locking mechanism 5 from accidentally sliding down, locking the entire mechanism in the extended state.

[0033] Folding process:

[0034] When folding is required, first move the movable lock 10 to disengage it from the protrusion 7, thus releasing the lock. Then, grasp the second locking mechanism 5 and slide it downwards (i.e., towards the grip) along the handle 1. Figure 2 As shown, as the second locking mechanism 5 moves downward, the connecting bar 6 (lower connecting bar) connected to it is pulled downward, thereby pulling the point where the upper and lower ends of the connecting frame 2 are connected toward the handle 1. Simultaneously, since the first locking mechanism 4 remains stationary, the connecting bar 6 (upper connecting bar) connected to it also changes angle, effectively pushing the point where the upper and upper ends of the connecting frame 2 are connected, causing the connecting frame 2 to undergo complex planar motion around its top pivot axis. Finally, when the second locking mechanism 5 slides to its lowest point, the two connecting bars 6 work together to drive the entire connecting frame 2, along with the rake teeth 3, to rotate to a position approximately parallel to the handle 1, as shown. Figure 3 As shown, the folding is complete, resulting in a neat and compact shape.

[0035] The unfolding process is the reverse of the above steps; simply push the second locking mechanism 5 upwards to the top and lock it.
