Description

A type of shovel Technical Field

[0001] This invention relates to the field of shovel technology, and more specifically to a shovel. Background Technology

[0002] Shovels are used for tasks such as shoveling soil and removing snow.

[0003] For example, Chinese utility model patent CN207531273U discloses a "Quick Connection Mechanism for a Plastic Shovel for Grain Threshing". This quick connection mechanism includes a shovel body and a shovel handle. A connecting part is formed on the upper part of the shovel body, and a connecting hole is formed in the connecting part. The outer wall of the connecting part is formed with external threads, and a retaining ring is set at the lower part of the external threads. A conical plug is formed at the lower end of the shovel handle, and a retaining ring is formed on the upper part of the conical plug. The conical plug mates with the connecting hole. There is also a plastic connecting nut with internal threads. One end of the connecting nut is formed with a compression ring. The internal threads of the connecting nut mate with the external threads of the connecting part of the shovel body, and the compression ring of the connecting nut contacts the retaining ring of the shovel handle.

[0004] However, the connection structure between the shovel body and the shovel handle in the above patent has the following problems: by setting nuts, etc., the nuts need to be turned during assembly, and sometimes hardware tools may be needed to tighten the nuts, so the operation is still not convenient enough. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a shovel with a connection and locking structure between the shovel body and the shovel handle that facilitates operation, in light of the current state of the prior art.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a shovel, comprising a shovel handle and a shovel head, wherein the shovel handle has a first end and a second end that are relatively distributed along its length; characterized in that it further comprises:

[0007] A locking element is movably secured to the second end of the shovel handle;

[0008] The shovel head has a mounting part with a mounting cavity extending along the length of the shovel handle, and a first opening and a second opening communicating with the mounting cavity. The second end of the shovel handle and the locking member can be inserted into or withdrawn from the mounting cavity through the first opening, and the second end of the shovel handle and the locking member can also extend out of the mounting cavity or retract into the mounting cavity through the second opening after being inserted into the mounting cavity.

[0009] When the second end of the shovel handle and the locking member are inserted into the mounting cavity and extend out of the mounting cavity from the second opening, the locking member is subjected to external force and has at least two states:

[0010] In the first state, the locking member does not interfere with the second opening of the mounting part, and the second end of the locking member and the shovel handle can be retracted into the mounting cavity of the mounting part through the second opening, and the shovel handle and the shovel head can be disengaged from each other.

[0011] In the second state, the locking member is located outside the mounting cavity of the mounting part and interferes with the second opening. The locking member cannot be retracted into the mounting cavity through the second opening, and the shovel handle and shovel head are locked together.

[0012] Specifically, the mating structure between the locking element and the shovel handle is that the second end of the shovel handle has two spaced-apart mounting arms and a connecting shaft located between the mounting arms;

[0013] The locking element is located between the two mounting arms and is fitted onto the connecting shaft in a manner that allows it to rotate about the axis of the connecting shaft.

[0014] In order to simultaneously meet the requirements of smooth rotation and locking, the locking component has a strip hole through which the connecting shaft passes and an elastic locking foot that extends into the strip hole;

[0015] The strip-shaped hole includes a first region and a second region that are interconnected along its length. The locking member can move along the length of the strip-shaped hole under the action of external force.

[0016] The locking element is subjected to external force and has at least four positions:

[0017] In the first position, the connecting shaft is located in the first area of ​​the strip hole, the elastic locking foot engages with the connecting shaft, and the locking member does not interfere with the second opening of the mounting part;

[0018] In the second position, the connecting shaft is located in the second region of the strip hole, the elastic locking foot is disengaged from the connecting shaft, and the locking member does not interfere with the second opening of the mounting part;

[0019] In the third position, the connecting shaft is located in the first area of ​​the strip hole, the elastic locking foot is engaged with the connecting shaft, the locking member is located outside the mounting cavity of the mounting part and interferes with the second opening, and the locking member abuts against the outer wall of the mounting part;

[0020] In the fourth position, the connecting shaft is located in the second region of the strip hole, the elastic locking foot is disengaged from the connecting shaft, and the locking member is located outside the mounting cavity of the mounting part and interferes with the second opening;

[0021] In the first state, the locking member has a first position and a second position;

[0022] In the second state, the locking member has a third position and a fourth position.

[0023] Thus, when the elastic locking foot disengages from the connecting shaft, it facilitates the smooth rotation of the locking component; when the elastic locking foot engages with the connecting shaft, it facilitates the locking or positioning of the locking component.

[0024] To facilitate smooth rotation of the locking element, the locking element has a curved edge;

[0025] When the locking member is in the third position, the arc-shaped edge is offset from the second opening of the mounting portion;

[0026] When the locking member is in the fourth position, the arc-shaped edge is aligned with the second opening of the mounting portion.

[0027] By setting the curved edge, the contact area with other parts is reduced, making rotation easier.

[0028] To facilitate the rotation of the locking element, the second end of the shovel handle also has clearance space between the two mounting arms and the connecting shaft.

[0029] During the rotational switching between the second and fourth positions of the locking member, the clearance space is used to avoid the arc-shaped edge.

[0030] To facilitate the removal of the shovel handle, in the first position, the arc-shaped edge of the locking member is inserted into the clearance space. In this way, the position of the locking member and the shovel handle is relatively fixed, and the locking member can remain in the required position during the removal of the shovel handle, thus facilitating the removal of the handle.

[0031] To facilitate user operation of the locking mechanism, a portion of the arc-shaped edge has a recessed portion that is recessed along the length of the strip hole;

[0032] In the third position, the recess is located on the side away from the mounting portion.

[0033] In this way, the user's finger can be inserted into the recess to facilitate the movement of the locking mechanism.

[0034] In order to position the locking element, the locking element has a positioning protrusion;

[0035] The mounting arm has a first positioning groove and a second positioning groove that are spaced apart.

[0036] When the locking member is switched from the second position to the first position, the positioning protrusion enters the first positioning groove.

[0037] When the locking member is switched from the fourth position to the third position, the positioning protrusion enters the second positioning groove.

[0038] Preferably, the groove wall where the first positioning groove is located extends with a support portion along the direction in which the positioning protrusion exits the first positioning groove. This support portion is used to support the positioning protrusion of the locking member upward when the shovel handle is in a laterally extended state. By providing the support portion, the locking member can be supported by supporting the positioning protrusion, and the position can be guided when the positioning protrusion enters the first positioning groove, making it easier for the positioning protrusion to align with the first positioning groove.

[0039] To prevent foreign objects from entering the locking member through the elastic locking foot, the locking member is in its third position, with the elastic locking foot hidden between the locking member and the mounting part of the shovel head. With the elastic locking foot hidden, snow, dust, sand, and other foreign objects will not enter through this location when shoveling snow. To facilitate user operation, the locking member includes a protruding actuating part with anti-slip texture. The user applies force to the actuating part to move the locking member, and the anti-slip texture increases friction.

[0040] The shovel handle can have various structures; preferably, the shovel handle includes...

[0041] The base, with the first end of the shovel handle located on one side of the base;

[0042] The connecting part has a first end fixed to the other side of the base, and a second end extending beyond the base. The second end of the connecting part forms the second end of the shovel handle and is movably constrained thereon by the locking member. The shovel handle can also be a single piece.

[0043] Compared with the prior art, the advantages of the present invention are as follows: during installation, after the second end of the shovel handle and the locking member are inserted into the mounting cavity of the shovel head through the first opening, they extend out of the mounting cavity through the second opening and then act on the locking member to make the locking member in the second state. In this way, the locking member connects the shovel handle and the shovel head, which is convenient for the user to operate, can realize the quick connection of the shovel handle and the shovel head, and has high installation efficiency.

[0066] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0067] Example 1:

[0068] Referring to Figures 1 to 13, a preferred embodiment of the shovel of the present invention is shown. The shovel includes a handle 1, a locking member 3, and a shovel head 2.

[0069] The shovel handle 1 has a first end and a second end that are relatively distributed along its length. Referring to Figure 13, the second end of the shovel handle 1 has two spaced-apart mounting arms 121 and a connecting shaft 122 located between the mounting arms 121. Specifically, referring to Figure 13, the shovel handle 1 includes a base 11 and a connecting portion 12. The first end of the shovel handle 1 is located on one side of the base 11, and the first end of the connecting portion 12 is fixed to the other side of the base 11 by a screw. The second end of the connecting portion 12 extends out of the base 11, forming the second end of the shovel handle 1 and being movably constrained thereon by a locking member 3. The mounting arms 121 have spaced-apart first positioning grooves 1211 and second positioning grooves 1212. Referring to Figures 6 to 11 and Figure 13, the shovel handle 1 also has a clearance space 13 spaced-apart from the connecting shaft 122 between the two mounting arms 121. This clearance space 13 communicates with the opening 212 of the mounting portion 21.

[0070] Referring to Figures 2 to 11, the locking member 3 is movably constrained on the second end of the shovel handle 1. The locking member 3 is located between the two mounting arms 121, and is sleeved on the connecting shaft 122 in a manner that allows it to rotate about the axis of the connecting shaft 122. Specifically, the locking member 3 has a slotted hole 31 through which the connecting shaft 122 passes, and an elastic locking foot 32 extending into the slotted hole 31; the slotted hole 31 includes a first region 311 and a second region 312 that are interconnected along its length direction, and the locking member 3 can move along the length direction of the slotted hole 31 under the action of external force. The locking member 3 also has an arc-shaped edge 33, a positioning protrusion 36, and a protruding actuating part 34. The actuating part 34 has an anti-slip texture 341, which can be horizontal or other shapes such as diamonds. A portion of the arc-shaped edge 33 has a recessed part 35 that is recessed along the length direction of the strip hole 31. In the third position described below, the recessed part 35 is located on the side away from the mounting part 21.

[0071] Referring to Figures 6 to 13, the shovel head 2 has a mounting portion 21, which is preferably located on the back side of the shovel head 2. The mounting portion 21 has a mounting cavity 211 extending along the length of the shovel handle 1, and a first opening 213 and a second opening 212 communicating with the mounting cavity 211. The second end of the shovel handle 1 and the locking member 3 can be inserted into or withdrawn from the mounting cavity 211 through the first opening 213, and after being inserted into the mounting cavity 211, the second end of the shovel handle 1 and the locking member 3 can also extend out of the mounting cavity 211 or retract into the mounting cavity 211 through the second opening 212.

[0072] Locking element 3 has different states and different positions, as detailed below.

[0073] When the second end of the shovel handle 1 and the locking member 3 are inserted into the mounting cavity 211 and extend out of the mounting cavity 211 from the second opening 212, the locking member 3 is subjected to external force and has two states:

[0074] In the first state, the locking member 3 does not interfere with the second opening 212 of the mounting part 21, and the second end of the locking member 3 and the shovel handle 1 can be retracted into the mounting cavity 211 of the mounting part 21 through the second opening 212, and the shovel handle 1 and the shovel head 2 can be disengaged from each other.

[0075] In the second state, the locking member 3 is located outside the mounting cavity 211 of the mounting part 21 and interferes with the second opening 212. The locking member 3 cannot be retracted into the mounting cavity 211 through the second opening 212, and the shovel handle 1 and the shovel head 2 are locked together.

[0076] Specifically, the locking element 3 is subjected to external force and has four positions:

[0077] Referring to Figures 9 and 11, in the first position, the connecting shaft 122 is located in the first region 311 of the strip hole 31, the elastic locking foot 32 is engaged with the connecting shaft 122, and the locking member 3 does not interfere with the second opening 212 of the mounting part 21; and in the first position, the arc-shaped edge 33 of the locking member 3 is inserted into the clearance space 13.

[0078] Referring to Figures 8 and 10, in the second position, the connecting shaft 122 is located in the second region 312 of the strip hole 31, the elastic locking foot 32 is disengaged from the connecting shaft 122, and the locking member 3 does not interfere with the second opening 212 of the mounting part 21;

[0079] Referring to Figure 6, in the third position, the connecting shaft 122 is located in the first region 311 of the strip hole 31, the elastic locking foot 32 is engaged with the connecting shaft 122, the locking member 3 is located outside the mounting cavity 211 of the mounting part 21 and interferes with the second opening 212, the locking member abuts against the outer wall of the mounting part 21, and the arc-shaped edge 33 is offset from the second opening 212 of the mounting part 21;

[0080] Referring to Figure 7, in the fourth position, the connecting shaft 122 is located in the second region 312 of the strip hole 31, the elastic locking foot 32 is disengaged from the connecting shaft 122, the locking member 3 is located outside the mounting cavity 211 of the mounting part 21 and interferes with the second opening 212, and the arc-shaped edge 33 is aligned with the second opening 212 of the mounting part 21.

[0081] In the first state, the locking member 3 has a first position and a second position;

[0082] In the second state, the locking element 3 has a third position and a fourth position.

[0083] During the rotational switching between the second and fourth positions of the locking member 3, the clearance space 13 is used to avoid the arc-shaped edge 33. When the locking member 3 switches from the second position to the first position, the positioning protrusion 36 enters the first positioning groove 1211 (see Figure 3). When the locking member 3 switches from the fourth position to the third position, the positioning protrusion 36 enters the second positioning groove 1212 (see Figure 2).

[0084] The working principle and usage process are as follows:

[0085] The initial state is shown in Figure 12. The shovel is divided into two parts: the handle 1 and the locking part 3 are one part, and the shovel head 2 is the other part.

[0086] When assembly is required, refer to Figure 12. Insert the locking member 3 and the shovel handle 1 into the mounting cavity 211 of the shovel head 2 through the first opening 213, and make the locking member 3 and the two mounting arms 121 extend out of the second opening 212 of the shovel head 2. From the position in Figure 9, pull the locking member 3 to the right to the position in Figure 8 by acting on the actuating part 34 of the locking member 3; then rotate the locking member 3 counterclockwise upward to the position in Figure 7 (that is, rotate to the position in Figure 7 with the direction of rotation as shown by the arrow in Figure 8); finally, push the locking member 3 downward to the position in Figure 6. In this way, the connecting shaft 122 is located in the first area 311 of the slot 31 of the locking member 3, the elastic locking foot 32 engages the connecting shaft 122, the locking member 3 abuts against the mounting part 21, and the locking member 3 connects the shovel handle 1 and the shovel head 2, thus realizing the quick connection of the shovel handle 1 and the shovel head 2. The operation is convenient and can be performed by hand, with high installation efficiency. The user can also insert their fingers into the recess 35 to act on the locking member 3. The assembled state is shown in Figures 2 and 6.

[0087] When disassembly is required, similarly, as shown in Figure 6, first push the locking piece 3 upwards to disengage the elastic locking foot 32 from the connecting shaft 122 (Figure 7). Then, rotate the locking piece 3 clockwise to the position shown in Figure 8. Next, as shown in Figure 8, push the locking piece 3 to the left to the position shown in Figure 9. The connecting shaft 122 re-engages with the elastic locking foot 32, and the left end of the locking piece 3 is located within the clearance space 13. At this time, the positions of the locking piece 3 and the shovel handle 1 are relatively fixed. Finally, pull the shovel handle 1 and the locking piece 3 out of the mounting part 21 of the shovel head 2. This disassembly method is convenient and quick, and facilitates transportation and storage after disassembly. The disassembly completed state is shown in Figure 12.

[0088] Example 2:

[0089] Referring to Figures 14 to 22, another preferred embodiment of the present invention is shown. The difference between the shovel in this embodiment and that in Embodiment 1 lies in the structure of the locking member 3 and the structure of the shovel handle 1. Details are as follows.

[0090] Referring to Figures 17-19, the actuating part 34 of the locking member 3 is roughly block-shaped, with the free end of the actuating part 34 extending outward and having a large outer perimeter, making it easy for the user to grip the actuating part 34. The positioning protrusion 36 is block-shaped, which makes it less prone to wear and provides a better positioning effect. Correspondingly, the shapes of the first positioning groove 1211 and the second positioning groove 1212 are adapted to the shape of the positioning protrusion 36.

[0091] Referring to Figures 15 and 20, with the locking member 3 in the third position, the elastic locking foot 32 is hidden between the locking member 3 and the mounting part 21 of the shovel head 2. With the elastic locking foot 32 hidden, snow, dust, sand, or other foreign objects will not enter through the position of the elastic locking foot 32 when performing operations such as shoveling snow.

[0092] Referring to Figure 21, the shovel handle 1 includes a base 11, a connecting part 12, and a plastic sleeve 13. The plastic sleeve 13 is fitted over the base 11. The base 11, the first end of the connecting part 12, and the plastic sleeve 13 are fixed by screws. The second end of the connecting part 12 extends out of the base 11 and forms the second end of the shovel handle 1, which is movably constrained by the locking member 3.

[0093] In addition, a support portion 123 (Figs. 14 and 16) extends from the groove wall where the first positioning groove 1211 is located along the direction in which the positioning protrusion 36 exits the first positioning groove 1211. This support portion 123 is used to support the positioning protrusion 36 of the locking member 3 upward when the shovel handle 1 is in a laterally extended state. During installation, the shovel handle 1 is usually placed in a laterally extended state. In this way, the support portion 123 is used to support the positioning protrusion 36 exiting the first positioning groove 1211 upward on the one hand, and to guide the position of the positioning protrusion 36 when it enters the first positioning groove 1211 on the other hand, so as to facilitate the alignment of the positioning protrusion 36 with the first positioning groove 1211.

[0094] The working principle and usage process are the same as in Example 1.
