Description

Technical Field

[0001] This application relates to the field of shovel technology, and in particular to a paper shovel. Background Technology

[0002] A shovel is a common hand tool. It's used to scoop up and move small objects like granules. For example, a shovel can be used to scoop up and move cat litter. Shovels are typically made from a single piece of molded plastic. However, shovels made of plastic are not very environmentally friendly, and discarded shovels can pollute the environment. Utility Model Content

[0003] This application provides a paper shovel that helps reduce the possibility of environmental pollution.

[0004] This application provides a paper shovel, which includes a bucket portion and a handle portion. The bucket portion includes a bottom plate, a first side plate, and a first wing plate. Along a first direction, the first side plates are respectively disposed on opposite sides of the bottom plate. Along a second direction, the bottom plate includes a front end and a rear end. A first wing plate is disposed at the end of the first side plate near the rear end. Two first wing plates are connected to form a second side plate. The bottom plate, the first side plate, and the second side plate are connected to form a receiving space. The handle portion includes a first plate body, a connecting plate, and a second plate body connected in sequence. The first plate body is connected to the rear end. Along a third direction, the first plate body and the second plate body are spaced apart. The handle portion also includes a fixing plate. A fixing plate is disposed at the end of the second plate body away from the connecting plate. The fixing plate is connected to the bucket portion. The fixing plate is located on the side of the second side plate facing the receiving space. The first direction, the second direction, and the third direction are perpendicular to each other.

[0005] The paper shovel of this embodiment includes a bucket section and a handle section. The bottom plate, first side plate, and first wing plate in the bucket section are connected to form a receiving space. The handle section is connected and fixed to the bucket section via a first plate and a fixing plate. The handle section facilitates user operation of the paper shovel, allowing for the scooping and transport of items using the bucket section. The paper shovel is made entirely of biodegradable paper material, thus possessing good environmental friendliness and reducing the potential for pollution.

[0006] In some feasible embodiments, the shovel handle also includes a second wing plate and a third wing plate. Along a first direction, the second wing plate is provided on opposite sides of the first plate body, and the third wing plate is provided on opposite sides of the second plate body. The second wing plate is folded toward the second plate body, and the third wing plate is folded toward the first plate body. The third wing plate is connected to the first plate body, and the second wing plate and the third wing plate with corresponding positions are stacked to form a third side plate.

[0007] The second plate is connected to the first plate via the third wing plate, which helps to improve the connection stability between the first and second plates, improve the overall structural strength of the shovel handle, and reduce the possibility of deformation of the shovel handle due to gripping force.

[0008] In some possible implementations, the first plate includes a first connecting hole, the shovel handle also includes a first insert plate, and the third wing plate is provided with the first insert plate at the end away from the second plate, the first insert plate being inserted into the first connecting hole.

[0009] After the first insert plate is inserted into the first connecting hole, the third wing plate can be fixed, making it less prone to springback. The insertion of the first insert plate into the first connecting hole facilitates the connection between the third wing plate and the first plate, reducing the difficulty of connecting them.

[0010] In some feasible ways, the shapes of the first connecting hole and the first insert plate are matched, and the first insert plate and the first connecting hole are interference-fitted.

[0011] The first insert plate folds towards the first connecting hole, and under the action of external force, the first insert plate can be inserted into the first connecting hole in a third direction. The interference fit between the first insert plate and the first connecting hole makes it difficult for the first insert plate to be removed from the first connecting hole, which helps to improve the connection stability between the first insert plate and the first connecting hole.

[0012] In some possible implementations, the base plate includes a second connecting hole, the shovel handle also includes a second insert plate, the end of the fixing plate away from the second plate body is provided with the second insert plate, and the second insert plate is inserted into the second connecting hole.

[0013] After the second insert plate is inserted into the second connecting hole, the bottom plate can form a limiting constraint on the fixed plate through the second insert plate, so that the fixed plate will not spring back, reducing the possibility of the fixed plate separating from the bucket part due to springback, and improving the connection stability between the second plate and the bottom plate.

[0014] In some feasible embodiments, the shovel handle also includes a limiting tongue, with the limiting tongue provided at the end of the fixing plate away from the second plate. The limiting tongue includes a clearance hole for avoiding the second insert plate, and the limiting tongue is inserted between the second side plate and the bottom plate.

[0015] When the limiting tongue is inserted between the second side plate and the bottom plate, the limiting tongue can limit and constrain the fixed plate, preventing the fixed plate from springing back and reducing the possibility of the fixed plate separating from the bucket part due to springback. This helps to improve the connection stability between the second plate and the bucket part, and improve the connection stability between the handle part and the bucket part.

[0016] In some feasible ways, the two first wing plates interlock to form the second side plate.

[0017] The two first wing plates are connected or separated by a snap-fit ​​mechanism, which facilitates the connection or separation of the two first wing plates, reduces the difficulty of connecting or separating the two first wing plates, and improves the efficiency of connecting or separating the two first wing plates.

[0018] In some feasible implementations, the first wing plate includes a snap hook, and the two first wing plates are secured by snap hooks.

[0019] The two first wing plates are connected by a snap-fit ​​mechanism, which limits each other in the first direction after the two first wing plates are connected, reducing the possibility of separation in the first direction and improving the connection stability of the two first wing plates.

[0020] In some feasible implementations, the base plate has sieve holes.

[0021] Crushed particles can pass through the screen holes, while uncrushed particles can remain in the bucket's containment space. The bottom plate can screen out uncrushed particles through the screen holes to reduce material waste.

[0022] In some feasible implementations, the second plate includes finger buckle holes.

[0023] When the user holds the shovel handle, their fingers can be inserted into the finger hook holes, which helps to improve the stability of the grip and reduces the possibility of the shovel handle slipping out of the user's hand.

[0024] In some feasible ways, the bucket and the handle are integrally formed.

[0025] A single sheet of paper blank is machined to form a flat paper shovel. Then, it is folded along the corresponding creases, and the components to be joined are connected to form a three-dimensional paper shovel. The method of molding the bucket and handle in one piece improves the overall structural strength of the paper shovel and also reduces the processing and assembly difficulty of the bucket and handle.

Figure 3 The structure of the paper shovel 10 in a flat position is schematically shown. Figure 4 The partially unfolded structure of the paper shovel 10 is schematically shown. To better understand this application, the following is combined with... Figures 1 to 4 Describe it.

[0056] See Figures 1 to 4 As shown, this application provides a paper shovel 10, which includes a bucket portion 20 and a handle portion 30.

[0057] The bucket section 20 includes a bottom plate 21, first side plates 22, and first wing plates 23. Along a first direction X, first side plates 22 are respectively provided on opposite sides of the bottom plate 21. Along a second direction Y, the bottom plate 21 includes a front end 21a and a rear end 21b. A first wing plate 23 is provided on the end of the first side plate 22 near the rear end 21b. Two first wing plates 23 are connected to form a second side plate 201. The bottom plate 21, first side plates 22, and second side plates 201 are connected to form a receiving space. The handle section 30 includes a first plate 31, a connecting plate 32, and a second plate 33 connected in sequence. The first plate 31 is connected to the rear end 21b. Along a third direction Z, the first plate 31 and the second plate 33 are spaced apart. The handle section 30 also includes a fixing plate 34. The fixing plate 34 is provided at the end of the second plate 33 away from the connecting plate 32. The fixing plate 34 is connected to the bucket section 20. The fixing plate 34 is located on the side of the second side plate 201 facing the receiving space. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0058] The paper shovel 10 of this embodiment can be used by a user holding the handle 30 and scooping up an item (e.g., cat litter) using the bucket 20, and then moving the item to a predetermined location. The bucket 20 has a accommodating space that can hold the item. When using the paper shovel 10, the front end 21a of the base plate 21 can be inserted into the item to be scooped up, so that the item enters the accommodating space of the bucket 20.

[0059] First side plates 22 are provided on both sides of the bottom plate 21, and a second side plate 201 is provided at the rear end 21b. The front end 21a of the bottom plate 21 is in an open state, which facilitates the entry of the object to be scooped into the receiving space of the bucket section 20. The first side plates 22 provided on both sides of the bottom plate 21 can serve as the left side plate and right side plate of the bucket section 20, respectively.

[0060] In this embodiment, the shovel handle 30 can be connected to the bucket part 20 via the first plate 31 and the fixing plate 34. When the fixing plate 34 is connected to the bucket part 20, the fixing plate 34 can limit and constrain the second plate 33, improve the positional stability of the second plate 33, and reduce the possibility of deformation of the shovel handle 30.

[0061] In this embodiment, the end of the first plate 31 away from the connecting plate 32 is connected to the bottom plate 21. The two opposite ends of the connecting plate 32 are respectively connected to the first plate 31 and the second plate 33. In the formed paper shovel 10, the connecting plate 32 and the second side plate 201 are spaced apart along the second direction Y. The first plate 31, the connecting plate 32, the second plate 33, and the second side plate 201 enclose and form a cavity.

[0062] When using the paper shovel 10, the user can hold the first plate 31 and the second plate 33 with their hands to operate the paper shovel 10 to scoop up and move related items.

[0063] The paper shovel 10 of this embodiment includes a bucket portion 20 and a handle portion 30. The bottom plate 21, first side plate 22, and first wing plate 23 of the bucket portion 20 are connected to form a receiving space. The handle portion 30 is connected and fixed to the bucket portion 20 via a first plate 31 and a fixing plate 34. The handle portion 30 facilitates the user's use of the paper shovel 10 and allows for scooping and transporting related items using the bucket portion 20. The paper shovel 10 is made entirely of biodegradable paper material, thus possessing good environmental friendliness and reducing the possibility of pollution.

[0064] In some feasible configurations, the two first flanges 23 are detachably connected. The fixing plate 34 is detachably connected to the bucket section 20.

[0065] After the two first wing plates 23 separate from each other, the first side plate 22 and the first wing plate 23 can be folded relative to the bottom plate 21 so that the first side plate 22, the first wing plate 23 and the bottom plate 21 are in a flat state. After the fixing plate 34 separates from the bucket part 20, the fixing plate 34, the second plate body 33 and the connecting plate 32 can be folded relative to the first plate body 31 so that the fixing plate 34, the second plate body 33, the connecting plate 32, the first plate body 31 and the bottom plate 21 are in a flat state. Along the second direction Y, the bottom plate 21, the first plate body 31, the connecting plate 32, the second plate body 33 and the fixing plate 34 are arranged sequentially. The paper shovel 10 of this embodiment can switch between a three-dimensional state and a flat state. When the paper shovel 10 is in a flat state, it is easy to store and collect.

[0066] When the paper shovel 10 is needed, the first side plate 22 and the first wing plate 23 can be folded relative to the bottom plate 21 and the two first wing plates 23 can be connected. The fixing plate 34, the second plate 33 and the connecting plate 32 can be folded relative to the first plate 31 and the fixing plate 34 can be connected to the bucket part 20 so that the paper shovel 10 can be switched from a flat state to a three-dimensional state.

[0067] See also some of the possible implementation methods. Figure 1 , Figure 3 and Figure 4 As shown, the shovel handle portion 30 also includes a second wing plate 35 and a third wing plate 36. Along the first direction X, the second wing plate 35 is disposed on opposite sides of the first plate body 31, and the third wing plate 36 is disposed on opposite sides of the second plate body 33. The second wing plate 35 is folded towards the second plate body 33. The third wing plate 36 is folded towards the first plate body 31. The third wing plate 36 is connected to the first plate body 31. The second wing plate 35 and the third wing plate 36, with corresponding positions, are stacked to form a third side plate 301.

[0068] The connection between the second plate 33 and the first plate 31 via the third wing plate 36 is beneficial to improving the connection stability between the first plate 31 and the second plate 33, improving the overall structural strength of the shovel handle 30, and reducing the possibility of the shovel handle 30 deforming due to gripping force.

[0069] The way in which the second wing plate 35 and the third wing plate 36 are stacked to form the third side plate 301 is beneficial to improving the structural strength of the third side plate 301, giving the third side plate 301 good compressive resistance and reducing the possibility of the third side plate 301 being deformed by gripping force.

[0070] In some examples, the second wing 35 is located inside the third wing 36.

[0071] In some examples, the first plate 31, connecting plate 32, second plate 33, second side plate 201, and third side plate 301 can enclose and form a cavity. The second wing plate 35 is located on the side of the third wing plate 36 facing the cavity.

[0072] In some examples, the third wing 36 is detachably connected to the first plate 31.

[0073] The process of switching the paper shovel 10 from a flat state to a three-dimensional state may include: folding the first side plate 22 and the first wing plate 23 relative to the bottom plate 21 and connecting the two first wing plates 23; folding the fixing plate 34, the second plate 33, and the connecting plate 32 relative to the first plate 31 and connecting the fixing plate 34 to the bucket part 20; folding the second wing plate 35 relative to the first plate 31 towards the second plate 33; folding the third wing plate 36 relative to the second plate 33 towards the first plate 31; and connecting and fixing the third wing plate 36 to the first plate 31, so that the paper shovel 10 switches to a three-dimensional state.

[0074] See in some examples Figure 2 , Figure 3 and Figure 4 As shown, the first plate 31 includes a first connecting hole 311. The shovel handle 30 also includes a first insert plate 37. The first insert plate 37 is disposed at the end of the third wing plate 36 away from the second plate 33. The first insert plate 37 is inserted into the first connecting hole 311.

[0075] After the first insert plate 37 is inserted into the first connecting hole 311, the third wing plate 36 can be fixed, making the third wing plate 36 less prone to springback. By inserting the first insert plate 37 into the first connecting hole 311, it is easier to connect the third wing plate 36 and the first plate 31, reducing the difficulty of connecting the third wing plate 36 and the first plate 31.

[0076] In some examples, a first insert plate 37 is provided in the middle region of the end of the third wing plate 36 away from the second plate 33.

[0077] In some examples, the shapes of the first connecting hole 311 and the first insert plate 37 are matched, and the first insert plate 37 and the first connecting hole 311 are interference-fitted.

[0078] The first insert plate 37 is folded towards the first connecting hole 311, and under the action of external force, the first insert plate 37 can be inserted into the first connecting hole 311 along the third direction Z. The first insert plate 37 and the first connecting hole 311 are interference-fitted, making it difficult for the first insert plate 37 to be removed from the first connecting hole 311, which helps to improve the connection stability between the first insert plate 37 and the first connecting hole 311.

[0079] In some examples, the first connecting hole 311 is trapezoidal. Along the first direction X, the first plate 31 includes two opposing side surfaces. The first connecting hole 311 has an opening located on the side surface. The opening size of the first connecting hole 311 is small. The first insert plate 37 is trapezoidal. Along the direction away from the third wing plate 36, the size of the first insert plate 37 increases. The small end of the first insert plate 37 is connected to the third wing plate 36. After the first insert plate 37 is inserted into the first connecting hole 311 along the third direction Z, in the first direction X, the first insert plate 37 is limited by the first plate 31, preventing the first insert plate 37 from exiting the first connecting hole 311 along the first direction X. This reduces the possibility of the first insert plate 37 exiting the first connecting hole 311 and causing separation between the first insert plate 37 and the first connecting hole 311, thus improving the connection stability between the first insert plate 37 and the first connecting hole 311.

[0080] In some examples, the first plate 31 is trapezoidal. The larger end of the first plate 31 is connected to the base plate 21. The smaller end of the first plate 31 is connected to the connecting plate 32. Along the first direction X, the first plate 31 includes two opposing side surfaces. The side surfaces are inclined. A second wing plate 35 is disposed on the side surface of the first plate 31.

[0081] The second plate 33 is trapezoidal, with its smaller end connected to the connecting plate 32. A fixing plate 34 is provided at the larger end of the second plate 33. Along the first direction X, the second plate 33 includes two opposing side surfaces. These side surfaces are inclined. A third wing plate 36 is provided on the side surface of the second plate 33.

[0082] In some examples, the fixed plate 34 is rectangular. The third wing plate 36 is rectangular.

[0083] In some examples, the base plate 21 is rectangular. The first side plate 22 is trapezoidal or right-angled triangular. The smaller end of the first side plate 22 is near the front end 21a of the base plate 21. The larger end of the first side plate 22 is near the rear end 21b of the base plate 21. A first wing plate 23 is provided at the larger end of the first side plate 22.

[0084] See also some of the possible implementation methods. Figures 1 to 4As shown, the base plate 21 includes a second connecting hole 211. The shovel handle portion 30 also includes a second insert plate 38. The second insert plate 38 is provided at the end of the fixing plate 34 away from the second plate body 33. The second insert plate 38 is inserted into the second connecting hole 211.

[0085] After the fixing plate 34 is folded relative to the second plate 33 toward the bottom plate 21, the second insert plate 38 is inserted into the second connecting hole 211. After the second insert plate 38 is inserted into the second connecting hole 211, the bottom plate 21 can form a limiting constraint on the fixing plate 34 through the second insert plate 38, so that the fixing plate 34 will not spring back, reducing the possibility that the fixing plate 34 will spring back and separate from the bucket part 20, and improving the connection stability between the second plate 33 and the bottom plate 21.

[0086] In some examples, the second connecting hole 211 is a strip-shaped hole. Exemplarily, the second connecting hole 211 is a rectangular hole. The length direction of the second connecting hole 211 is the same as the first direction X. The width direction of the second connecting hole 211 is the same as the second direction Y. The second insert plate 38 has a long strip-shaped structure.

[0087] In some examples, a second insert plate 38 is disposed in the middle region of the end of the fixing plate 34 away from the second plate body 33.

[0088] See in some examples Figure 3 and Figure 4 As shown, the shovel handle portion 30 also includes a limiting tongue 39. The limiting tongue 39 is provided at the end of the fixing plate 34 away from the second plate body 33. The limiting tongue 39 includes a clearance hole 391 for avoiding the second insert plate 38. The limiting tongue 39 is inserted between the second side plate 201 and the bottom plate 21.

[0089] With the paper shovel 10 laid flat, the second insert plate 38 is located inside the clearance hole 391, so that there is no positional interference between the second insert plate 38 and the limiting tongue 39.

[0090] When the limiting tongue 39 is inserted between the second side plate 201 and the bottom plate 21, the limiting tongue 39 can limit and constrain the fixed plate 34, so that the fixed plate 34 will not spring back, reducing the possibility that the fixed plate 34 will spring back and separate from the bucket part 20. This is beneficial to improving the connection stability between the second plate 33 and the bucket part 20, and improving the connection stability between the handle part 30 and the bucket part 20.

[0091] For example, the limiting tongue 39 is trapezoidal. The large end of the limiting tongue 39 is connected to the fixing plate 34.

[0092] In some feasible embodiments, the two first wing plates 23 are interlocked to form the second side plate 201. The two first wing plates 23 are connected or separated by interlocking, which facilitates the connection or separation of the two first wing plates 23, reduces the difficulty of connecting or separating the two first wing plates 23, and improves the efficiency of connecting or separating the two first wing plates 23.

[0093] See in some examples Figure 2 and Figure 3 As shown, the first wing plate 23 includes a latch 231. The two first wing plates 23 are fixed together by the latch 231.

[0094] When it is necessary to connect the two first wing plates 23, the first side plate 22 and the first wing plate 23 are folded relative to the bottom plate 21, and then the first wing plate 23 is folded relative to the first side plate 22, so that the two first wing plates 23 are brought closer to each other. Along the third direction Z, the latch 231 of one wing plate 23 is aligned with the latch 231 of the other wing plate 23. One first wing plate 23 is moved along the third direction Z until the latch 231 of one first wing plate 23 engages with the latch 231 of the other first wing plate 23, and the two first wing plates 23 are engaged.

[0095] The two first wing plates 23 are connected by hooks 231, so that after the two first wing plates 23 are connected, the two first wing plates 23 form a limit on each other in the first direction X, reducing the possibility of the two first wing plates 23 separating in the first direction X and improving the connection stability of the two first wing plates 23.

[0096] See also some of the possible implementation methods. Figure 3 and Figure 4 As shown, the bottom plate 21 has sieve holes 212. Crushed particles can pass through the sieve holes 212, while uncrushed particles can remain in the bucket's accommodating space. The bottom plate 21 can screen out uncrushed particles through the sieve holes 212 to reduce material waste.

[0097] In some examples, the base plate 21 is provided with two or more rows of sieve holes 212. The two or more rows of sieve holes 212 are spaced apart along the first direction X.

[0098] For example, in any two adjacent rows of sieve holes 212, the area of ​​any sieve hole 212 in the row of sieve holes 212 closer to the front end 21a is smaller than the area of ​​any sieve hole 212 in the row of sieve holes 212 farther from the end.

[0099] For example, the sieve hole 212 is a strip-shaped hole. In any two adjacent rows of sieve holes 212, the width of any sieve hole 212 in the row closer to the front end 21a is smaller than the width of any sieve hole 212 in the row farther from the end. For example, the sieve hole 212 can be an oblong hole or a rectangular hole.

[0100] See also some of the possible implementation methods. Figure 1 As shown, the second plate 33 includes finger-holding holes 331. When the user holds the shovel handle 30, the user's fingers can be inserted into the finger-holding holes 331, which helps to improve the stability of the hand holding the shovel handle 30 and reduces the possibility of the shovel handle 30 falling off the user's hand.

[0101] In some examples, the first plate 31, the connecting plate 32, the second plate 33, the second side plate 201, and the third side plate 301 enclose a cavity. The finger buckle hole 331 communicates with this cavity.

[0102] In some examples, the finger buckle hole 331 is a circular hole.

[0103] In some feasible ways, the bucket section 20 and the handle section 30 are integrally formed.

[0104] A single sheet of paper blank is machined to form a flat paper shovel 10. Then, it is folded along the corresponding creases, and the structures to be connected are joined to finally form a three-dimensional paper shovel 10. The method of integrally molding the bucket part 20 and the handle part 30 is beneficial to improving the overall structural strength of the paper shovel 10, and also helps to reduce the processing and assembly difficulty of the bucket part 20 and the handle part 30.

[0105] In some examples, a single sheet of paper blank is machined to form a flat paper shovel 10. The paper shovel 10 includes a base plate 21, a first side plate 22, a first wing plate 23, a first plate body 31, a connecting plate 32, a second plate body 33, a fixing plate 34, a second insert plate 38, a limiting tongue 39, a second wing plate 35, a third wing plate 36, and a first insert plate 37. The base plate 21 has a sieve hole 212 and a second connecting hole 211. The first wing plate 23 has a hook 231. The first plate body 31 has a first connecting hole 311. The second plate body 33 has a finger hook hole 331.

[0106] There is a crease between the first side plate 22 and the bottom plate 21. There is a crease between the first wing plate 23 and the first side plate 22. There is no crease between the first plate 31 and the bottom plate 21. The first plate 31 and the bottom plate 21 have a smooth transition. There is a crease between the second wing plate 35 and the first plate 31. There is a crease between the first plate 31 and the connecting plate 32. There is a crease between the connecting plate 32 and the second plate 33. There is a crease between the second plate 33 and the fixing plate 34. There is no crease between the fixing plate 34 and the second insert plate 38. The fixing plate 34 and the second insert plate 38 have a smooth transition. There is a crease between the fixing plate 34 and the limiting tongue 39. There is a crease between the second plate 33 and the third wing plate 36. There is a crease between the third wing plate 36 and the first insert plate 37.

[0107] The process of switching the paper shovel 10 from a flat state to a three-dimensional state may include: folding the first side plate 22 relative to the bottom plate 21; folding the first wing plate 23 relative to the first side plate 22 and connecting the two first wing plates 23; folding the second wing plate 35; folding the connecting plate 32 and the second plate body 33 relative to the first plate body 31; stacking the fixing plate 34 and the first wing plate 23; and inserting the second insert plate 38 into the second connecting hole 211 of the bottom plate 21; folding the limiting tongue 39 relative to the fixing plate 34 and inserting the limiting tongue 39 between the first wing plate 23 and the bottom plate 21; folding the third wing plate 36 relative to the second plate body 33; and inserting the first insert plate 37 into the first connecting hole 311 of the first plate body 31 to form the three-dimensional paper shovel 10.

[0108] The process of the paper shovel 10 switching from a three-dimensional state to a flat state can be the reverse of the above process, and will not be described in detail here.

[0109] When the paper shovel 10 is switched from a flat state to a three-dimensional state and maintained in a three-dimensional state, no adhesive is needed to connect the bucket part 20 and the handle part 30, which helps to improve the overall environmental performance of the paper shovel 10.
