[0002] The shovel is used for shoveling soil, removing snow, etc.

[0003] For example, the Chinese utility model patent with announcement number CN207531273U discloses a "quick connection mechanism for a plastic shovel for grain threshing". The quick connection mechanism includes a shovel body and a shovel handle. A connecting part is formed on the upper part of the shovel body, a connecting hole is formed in the connecting part, an outer wall of the connecting part is formed with an external thread, a retaining ring is arranged at the lower part of the external thread, a conical plug is formed at the lower end of the shovel handle, a retaining ring is formed at the upper part of the conical plug, the conical plug cooperates with the connecting hole, and there is a connecting nut made of plastic, an internal thread is formed in the connecting nut, an extrusion ring is formed at one end of the connecting nut, the internal thread of the connecting nut cooperates with the external thread of the connecting part of the shovel body, and the extrusion ring of the connecting nut contacts with 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 a nut, etc., the nut needs to be turned during assembly, and sometimes hardware tools may be needed to tighten the nut, which 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 a shovel body and a shovel handle, which is convenient for operation, in view of the current status of the prior art.

[0006] The technical solution adopted by the present invention to solve the above technical problems is: a shovel, including a shovel handle and a shovel head, the shovel handle has a first end and a second end that are relatively distributed along the length direction; it is characterized by also comprising:

[0007] A locking member movably constrained on the second end of the shovel handle;

[0008] The shovel head has a mounting portion, the mounting portion has a mounting cavity penetrating along the length direction 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with the mounting cavity, the second end of the shovel handle and the locking piece can be inserted into or withdrawn from the mounting cavity from the first opening, and the second end of the shovel handle and the locking piece can also extend out of the mounting cavity from the second opening or retract into the mounting cavity 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 acted upon by an 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 portion, the locking member and the second end of the shovel handle can be retracted into the mounting cavity of the mounting portion 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 portion and interferes with the second opening, so that the locking member cannot be withdrawn into the mounting cavity through the second opening, and the shovel handle and the shovel head are locked and connected.

[0012] The matching structure between the locking member and the shovel handle is specifically that the second end of the shovel handle has two installation arms distributed at intervals and a connecting shaft located between the installation arms;

[0013] The locking member is located between the two mounting arms and is sleeved on the connecting shaft in a manner that the locking member can rotate around the axis of the connecting shaft.

[0014] In order to meet the requirements of smooth rotation and locking at the same time, the locking piece has a strip hole for the connecting shaft to pass through and an elastic clamping foot extending into the strip hole;

[0015] The strip-shaped hole comprises a first region and a second region which are interconnected along its length direction, and the locking member can move along the length direction of the strip-shaped hole under the action of an external force;

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

[0017] In the first position, the connecting shaft is in the first area of ​​the strip hole, the elastic foot is engaged with the connecting shaft, and the locking member has no interference with the second opening of the mounting portion;

[0018] In the second position, the connecting shaft is in the second area of ​​the strip hole, the elastic foot is disengaged from the connecting shaft, and the locking member has no interference with the second opening of the mounting portion;

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

[0020] In the fourth position, the connecting shaft is in the second area of ​​the strip hole, the elastic foot is disengaged from the connecting shaft, and the locking member is located outside the mounting cavity of the mounting portion 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] In this way, when the elastic clamping foot is disengaged from the connecting shaft, it is conducive to the smooth rotation of the locking member, and when the elastic clamping foot is engaged with the connecting shaft, it is conducive to the locking or positioning of the locking member.

[0024] In order to facilitate the smooth rotation of the locking piece, the locking piece has an arc-shaped 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] The arc-shaped edge is provided to reduce the contact area with other parts and facilitate rotation.

[0028] In order to facilitate the rotation of the locking member, the second end of the shovel handle also has an escape space spaced apart from the connecting shaft between the two mounting arms;

[0029] During the rotation switching process of the locking member between the second position and the fourth position, the avoidance space is used to avoid the arc-shaped edge.

[0030] In order to facilitate the removal of the shovel handle, in the first position, the arc edge of the locking member is inserted into the avoidance space. In this way, the positions of the locking member and the shovel handle are relatively fixed, and during the removal of the shovel handle, the locking member can be maintained in a required position, thereby facilitating the removal of the handle.

[0031] In order to facilitate the user to act on the locking member, a part of the arc-shaped edge has a recessed portion that is recessed along the length direction of the strip-shaped hole;

[0032] In the third position, the recessed portion is located at a side away from the mounting portion.

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

[0034] In order to locate the position of the locking member, the locking member has a positioning protrusion;

[0035] The mounting arm is provided with a first positioning groove and a second positioning groove which are spaced apart from each other;

[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 switches from the fourth position to the third position, the positioning protrusion enters the second positioning groove.

[0038] Preferably, a support portion is extended from the groove wall where the first positioning groove is located along the direction in which the positioning protrusion exits the first positioning groove, and the support portion is used to support the positioning protrusion of the locking member upward when the shovel handle is in a transversely extended state. By providing the support portion, the locking member can be supported by supporting the positioning protrusion, and the position of the positioning protrusion can be guided when the positioning protrusion enters the first positioning groove, so that the positioning protrusion is aligned with the first positioning groove.

[0039] In order to prevent foreign matter from entering the locking member from the position of the elastic foot, the locking member is in the third position, and the elastic foot is hidden between the locking member and the mounting portion of the shovel head. In this way, the elastic foot is hidden, and when the shovel is used to shovel snow, foreign matter such as snow, dust, and sand will not enter from the position of the elastic foot. In order to facilitate the user to act on the locking member, the locking member includes a protruding toggle portion, and the toggle portion has anti-slip textures. The user drives the locking member to move by applying force to the toggle portion, and the anti-slip textures are conducive to increasing friction.

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

[0041] A base, wherein the first end of the shovel handle is disposed on one side of the base;

[0042] The connecting part has a first end fixed to the other side of the base, a second end extending out of the base, and the second end of the connecting part forming the second end of the shovel handle and being movably restrained thereon by the locking member. The shovel handle can also be an integral piece.

[0043] Compared with the prior art, the advantages of the present invention are: during installation, the second end of the shovel handle and the locking piece are inserted into the installation cavity of the shovel head from the first opening, and then extended out of the installation cavity from the second opening, and then the locking piece is acted on to put the locking piece in the second state, so that the locking piece connects the shovel handle and the shovel head, which is convenient for users to operate, can achieve quick connection between the shovel handle and the shovel head, and has high installation efficiency.

[0080] See also Figure 7 In the fourth position, the connecting shaft 122 is in the second area 312 of the strip hole 31, the elastic foot 32 is disengaged from the connecting shaft 122, the locking member 3 is located outside the mounting cavity 211 of the mounting portion 21 and interferes with the second opening 212, and the arc edge 33 is aligned with the second opening 212 of the mounting portion 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 member 3 has a third position and a fourth position.

[0083] During the rotation switching process of the locking member 3 between the second position and the fourth position, the avoidance space 13 is used to avoid the arc 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 is switched 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 Fig.12 As shown, the shovel is divided into two parts, the shovel handle 1 and the locking piece 3 are one part, and the shovel head 2 is another part.

[0086] When assembly is required, see Fig.12 , insert the locking member 3 and the shovel handle 1 into the mounting cavity 211 of the shovel head 2 from 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; Fig. 9 From the position of the locking member 3, the toggle portion 34 of the locking member 3 is acted on to pull the locking member 3 to the right. Figure 8 Position; then turn the locking piece 3 upward counterclockwise to Figure 7 Position (that is, Figure 8 The direction indicated by the arrow is the rotation direction. Figure 7 position); finally push the locking piece 3 downward to Figure 6 The connection shaft 122 is located in the first area 311 of the strip hole 31 of the locking member 3, the elastic clamping foot 32 clamps the connection shaft 122, the locking member 3 abuts against the mounting portion 21, and the locking member 3 connects the shovel handle 1 and the shovel head 2, thus realizing a quick connection between the shovel handle 1 and the shovel head 2. The operation is convenient, and the user can operate it with bare hands, which has high installation efficiency. The user can also insert a finger into the recessed portion 35 to act on the locking member 3. The assembled state is as follows: Figure 2 , Figure 6 shown.

[0087] When disassembly is required, similarly, Figure 6 First, push the locking member 3 upward to disengage the elastic foot 32 from the connecting shaft 122 ( Figure 7 ), and then rotate the locking member 3 clockwise to Figure 8 Location, then from Figure 8 Push the locking piece 3 to the left. Fig. 9The connecting shaft 122 is re-engaged with the elastic foot 32, and the left end of the locking member 3 is located in the avoidance space 13. At this time, the positions of the locking member 3 and the shovel handle 1 are relatively fixed. Finally, the shovel handle 1 and the locking member 3 can be pulled out from the mounting portion 21 of the shovel head 2. This is also convenient and quick to disassemble, and it is easy to transport and store after disassembly. Fig.12 shown.

[0088] Embodiment 2:

[0089] See also Figure 14 to Figure 22 , which is another preferred embodiment of the present invention. The difference between the shovel of this embodiment and the embodiment 1 is that the structure of the locking member 3 is different and the structure of the shovel handle 1 is different. The details are as follows.

[0090] See also Figure 17 to Figure 19 The toggle portion 34 of the locking member 3 is generally block-shaped, and the free end of the toggle portion 34 extends outward and has a larger outer circumference, which makes it easier for the user to hold the toggle portion 34. The positioning protrusion 36 is block-shaped, which is not easy to wear and has 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] See also Fig.15 , Fig. 20 , the locking member 3 is in the third position, and the elastic foot 32 is hidden between the locking member 3 and the mounting portion 21 of the shovel head 2. In this way, the elastic foot 32 is hidden, and when the shovel is used to shovel snow, foreign objects such as snow, dust, and sand will not enter from the position of the elastic foot 32.

[0092] See also Fig.21 The shovel handle 1 includes a base 11 and a connecting portion 12, and also includes a plastic sleeve 13. The plastic sleeve 13 is sleeved outside the base 11, and the base 11, the first end of the connecting portion 12, and the plastic sleeve 13 are fixed by screws, and the second end of the connecting portion 12 extends out of the base 11, and the second end of the connecting portion 12 forms the second end of the shovel handle 1 and is movably constrained by the locking member 3.

[0093] In addition, a support portion 123 ( Fig.14 , Fig.16 ), the 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 transversely extended state. During installation, the shovel handle 1 is usually placed in a transversely extended state, so that the support portion 123 is used to support the positioning protrusion 36 withdrawing from the first positioning groove 1211 upward on the one hand, and to guide the positioning protrusion 36 when it enters the first positioning groove 1211 on the other hand, so that the positioning protrusion 36 is aligned with the first positioning groove 1211.

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