Description

Technical Field

[0001] This application relates to the technical field of agricultural implements, and in particular to a foldable shovel. Background Technology

[0002] A shovel is a common hand tool for digging and shoveling, typically consisting of a metal shovel-shaped head and a long handle. Its main functions include digging loose or soft materials such as soil, sand, gravel, and coal, and it can also be used to scoop up and transfer materials. The shovel head is mostly made of stamped or forged steel plate, and the edges are often reinforced to improve durability and digging efficiency. Depending on the usage scenario and function, shovels can be divided into various types such as square-headed shovels, round-headed shovels, and pointed shovels. They are widely used in agriculture, construction, landscaping, disaster relief, and outdoor activities. Some shovels are also designed with foldable or detachable structures for easy carrying and storage, making them an indispensable traditional tool in modern production and life.

[0003] Traditional folding shovels, as common portable tools, have solved the problems of transportation and storage to some extent, but they still have obvious drawbacks. Most folding shovels on the market use simple hinge or plug-in structures to fold or disassemble the handle. Such structures often rely on bolts or clips for fixing, and the disassembly and assembly process requires additional tools, which is cumbersome. Moreover, after repeated use, they are prone to loosening, causing the connection to wobble, which seriously affects the stability and safety of use. Utility Model Content

[0004] To improve strength and facilitate disassembly, this application provides a foldable shovel.

[0005] This application provides a foldable shovel, which adopts the following technical solution: A foldable shovel includes a shovel head, a first connecting rod fixedly connected to the rear outer surface of the shovel head, a handle provided on the rear outer surface of the first connecting rod, a drive rod movably connected to the rear outer surface of the handle, a handle fixedly connected to the rear outer surface of the drive rod, a reinforcing rod fixedly connected to the front outer surface of the drive rod, an external threaded connector fixedly connected to the front outer surface of the handle, and a fixing screw inserted through the upper outer surface of the first connecting rod.

[0006] As an optimized solution of this application, the outer wall of the reinforcing rod is provided with an external thread, and the inner wall of the handle is provided with a first internal thread and a second internal thread, which are compatible with the external thread.

[0007] As an optimized solution of this application, a first circular through hole is provided on the outer surface of the rear end of the handle, and the handle is movably connected to the drive rod through the first circular through hole.

[0008] As an optimized solution of this application, the inner surface of the rear end of the first connecting rod is provided with a third internal thread that is compatible with the external thread connector, and the first connecting rod is threadedly connected to the external thread connector through the third internal thread.

[0009] As an optimized solution of this application, the upper outer surface of the external threaded connector is provided with a fourth internal thread that is compatible with the fixing screw, and the external threaded connector is threadedly connected to the fixing screw through the fourth internal thread.

[0010] As an optimized solution of this application, a circular through hole adapted to the fixing screw is provided on the upper outer surface of the first connecting rod, and the first connecting rod is movably connected to the fixing screw through the circular through hole.

[0011] As an optimized solution of this application, the inner wall of the handle is provided with a movable groove that matches the reinforcing rod, and the handle is movably connected to the reinforcing rod through the movable groove.

[0012] As an optimized solution of this application, the outer wall of the handle is provided with a mounting groove, and a rubber sleeve is fixedly connected to the inner wall of the mounting groove.

[0013] In summary, this application includes at least one of the following beneficial technical effects: The foldable shovel of this application significantly improves the ease of assembly and disassembly, operational stability, and overall structural strength of the shovel through a multi-segment threaded connection and movable engagement structure. Specifically, the shovel head is fixedly connected to the first connecting rod, which achieves a reliable threaded connection with the external threaded connector at the front end of the handle through a third internal thread. This method not only ensures a strong connection but also allows for manual assembly and disassembly without additional tools, greatly simplifying the assembly and disassembly process. Simultaneously, the handle and drive rod are hinged through a first circular through-hole, allowing the shovel to fold along this axis, reducing its storage volume. A reinforcing rod is located at the drive rod... The external thread on the outer wall of the front end of the moving rod can be screwed into the first or second internal thread on the inner wall of the handle. When in the unfolded state, the thread locks in, forming additional support and effectively enhancing the bending and torsional resistance of the connection area between the handle and the driving rod. This avoids the problems of loosening and shaking that are common in traditional pure hinge structures. In addition, the fixing screw passes through the circular hole of the first connecting rod and is screwed into the fourth internal thread at the upper end of the external thread connector, further reinforcing the connection interface between the shovel head and the handle. This prevents deflection or disengagement during use and significantly improves the reliability and durability of the shovel under high-load operating conditions.

[0014] This application features a rubber sleeve on the handle, providing a comfortable and non-slip grip and reducing fatigue during prolonged use, making it particularly suitable for harsh outdoor environments. The movable groove design between the reinforcing rod and the handle allows the reinforcing rod to move along the groove when not locked, providing space for the folding process and allowing users to adjust the locking position according to their needs, thus enhancing structural adaptability and functional flexibility. Overall, this shovel, through the organic combination of threaded connection and movable joint, maintains its portable folding function while thoroughly improving key defects of traditional folding shovels such as insufficient rigidity, easy loosening, and cumbersome assembly and disassembly.

[0017] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0018] See Figure 1-4 A foldable shovel includes a shovel head 1, a first connecting rod 3 fixedly connected to the outer rear end of the shovel head 1, a handle 4 provided on the outer rear end of the first connecting rod 3, a drive rod 5 movably connected to the outer rear end of the handle 4, a handle 6 fixedly connected to the outer rear end of the drive rod 5, a reinforcing rod 9 fixedly connected to the outer front end of the drive rod 5, an external threaded connector 7 fixedly connected to the outer front end of the handle 4, and a fixing screw 2 inserted through the outer upper end of the first connecting rod 3.

[0019] The outer wall of the reinforcing rod 9 is provided with an external thread, and the inner wall of the handle 4 is provided with a first internal thread 8 and a second internal thread 10, which are compatible with the external thread.

[0020] A first circular through hole is provided on the outer surface of the rear end of the handle 4, and the handle 4 is movably connected to the drive rod 5 through the first circular through hole.

[0021] The shovel head 1 and the first connecting rod 3 are fixedly connected, forming the main body of the shovel. When assembling the shovel, first screw the external threaded connector 7 at the front end of the handle 4 into the third internal thread on the inner surface of the rear end of the first connecting rod 3 to achieve a reliable connection between the handle 4 and the first connecting rod 3. To further enhance the torsional and bending strength of this connection point, the fixing screw 2 can be inserted from the circular through hole at the upper end of the first connecting rod 3 and screwed into the fourth internal thread at the upper end of the external threaded connector 7. The screw tightening method prevents the threaded connection from loosening due to stress during use. Alternatively, the handle 4 and the drive rod 5 are movably connected through the first circular through hole at their rear ends, allowing the drive rod 5 to rotate relative to the handle 4, thereby achieving a folding function. The reinforcing rod 9 at the front end of the drive rod 5 has an external thread on its outer side. When the shovel is in the unfolded working state, the reinforcing rod 9 can be screwed into the first internal thread 8 or the second internal thread 10 on the inner wall of the handle 4, so that an additional rigid support is formed between the drive rod 5 and the handle 4, which greatly improves the stability of the overall structure and avoids the shaking or insufficient strength problems caused by relying on a single hinge point.

[0022] The inner surface of the rear end of the first connecting rod 3 is provided with a third internal thread that is compatible with the external thread connector 7. The first connecting rod 3 is threadedly connected to the external thread connector 7 through the third internal thread.

[0023] The upper outer surface of the external threaded connector 7 is provided with a fourth internal thread that is compatible with the fixing screw 2. The external threaded connector 7 is threadedly connected to the fixing screw 2 through the fourth internal thread.

[0024] The upper outer surface of the first connecting rod 3 is provided with a circular through hole that matches the fixing screw 2. The first connecting rod 3 is movably connected to the fixing screw 2 through the circular through hole.

[0025] The inner wall of the handle 4 is provided with a movable groove that matches the reinforcing rod 9, and the handle 4 is movably connected to the reinforcing rod 9 through the movable groove.

[0026] The outer wall of the handle 6 has a mounting groove, and a rubber sleeve is fixedly connected to the inner wall of the mounting groove.

[0027] When folding and storing, first loosen and remove the fixing screw 2 to release the additional lock between the first connecting rod 3 and the handle 4. Then, unscrew the reinforcing rod 9 from the internal thread of the handle 4, allowing the drive rod 5 to rotate freely around the hinge axis at the first circular through hole. Fold downwards to reduce the overall length. The movable groove on the inner wall of the handle 4 provides guidance and accommodation space for the movement of the reinforcing rod 9, ensuring a smooth and interference-free folding process. Finally, the main components achieve a compact folding of the shovel through the separation of the threaded connection points and the rotation of the movable hinge, facilitating transportation and storage. The rubber sleeve on the outer wall of the handle 6 not only provides users with a comfortable and non-slip grip experience but also effectively reduces the vibration transmitted to the hand during operation. In summary, this shovel, through its ingenious structural design combining threaded locking and movable hinges, ensures both overall rigidity and reliability in the working state and achieves convenient operation for quick folding and unfolding.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
