[0207] In addition, the technical features involved in the different embodiments of the utility model described below can be combined with each other as long as there is no conflict.

[0208] The embodiments of the utility model are described below in combination with Figures 1-33 .

[0209] According to the embodiments of the utility model, a dustpan is provided, as shown in Figure 1 , comprising: a dustpan hopper 1, a rotating rod 2 and a locking assembly 3.

[0210] The end of the dustpan hopper 1 along the length direction has a dustpan edge 101, through which garbage can enter the inside of the dustpan hopper 1; one end of the rotating rod 2 is rotatably arranged on the dustpan hopper 1, so that the rotating rod 2 can rotate relative to the dustpan hopper 1 along the length direction of the dustpan hopper 1, so that the dustpan is in a folded state or a working state; the locking assembly 3 is drivingly connected between the dustpan hopper 1 and the rotating rod 2; wherein the locking assembly 3 can rotate along the circumferential direction of itself, so that the locking assembly 3 switches between the unlocking state and the locking state; when the locking assembly 3 is in the unlocking state, the rotating rod 2 can rotate relative to the dustpan hopper 1 along the length direction of the dustpan hopper 1, so as to approach or move away from the dustpan edge 101, so that the dustpan is in a folded state; when the locking assembly 3 is in the locking state, the rotation of the rotating rod 2 along the length direction of the dustpan hopper 1 is limited.

[0211] In the above embodiment, a locking component 3 is provided between the winnowing basket 1 and the rotating rod 2. By rotating the locking component 3 in its circumferential direction, it changes between its unlocked and locked states, controlling the rotating rod 2 of the winnowing basket to be in a rotatable state and a restricted non-rotatable state, respectively. When the locking component 3 is in the unlocked state, that is, when the rotating rod 2 can rotate, the rotating rod 2 is folded to facilitate the storage of the winnowing basket. When the locking component 3 is in the locked state, that is, when the rotation of the rotating rod 2 is restricted, the position of the rotating rod 2 is kept fixed to ensure the normal operation of the winnowing basket. This solves the problem that the winnowing basket rod 5 is easily folded incorrectly during use of current foldable winnowing baskets, improving the user experience.

[0212] In this embodiment, the length direction of the winnowing basket 1 is parallel to... Figure 2 The first rotating shaft 303 in the winnowing basket shown is oriented in the same direction as the width of the winnowing basket 1. Figure 3 The first rotating shaft 303 in the winnowing basket shown in the diagram has the same orientation.

[0213] Specifically, such as Figure 2 , Figure 3 As shown, the rotating rod 2 can be used as a connector for the winnowing basket rod 5. The winnowing basket rod 5 is connected to the rotating rod 2 as an extension rod for user convenience.

[0214] This embodiment features a winnowing basket with two types of locking components 3.

[0215] The first embodiment of the winnowing basket is described below.

[0216] In some embodiments, such as Figure 4 , Figure 5 , Figure 6 As shown, the locking assembly 3 includes a first rotating part 301 and a second rotating part 302 connected to each other. The rotating rod 2 is connected to the winnowing basket 1 through the first rotating part 301 and the second rotating part 302. The first rotating part 301 is rotatably connected to the rotating rod 2 through a first rotating shaft 303, so that the rotating rod 2 is rotatably mounted on the winnowing basket 1 and can rotate about the axis of the first rotating shaft 303 to move closer to or away from the winnowing basket edge 101, so that the winnowing basket is in a folded state. The second rotating part 302 is circumferentially rotatably connected to the winnowing basket 1, and The rotating rod 2 can rotate relative to the hopper 1 in its own circumference, so that when the rotating rod 2 rotates in its own circumference, it can drive the first rotating part 301 and the second rotating part 302 to rotate synchronously in the circumference, thereby driving the first rotating shaft 303 to rotate in the circumference, so that the locking assembly 3 rotates to the unlocked state or the locked state; when the locking assembly 3 is in the unlocked state, the axial direction of the first rotating shaft 303 is perpendicular to the length direction of the hopper 1; when the locking assembly 3 is in the locked state, the axial direction of the first rotating shaft 303 is not perpendicular to the length direction of the hopper 1.

[0217] In the above embodiment, the locking assembly 3 is composed of the first rotating part 301 and the second rotating part 302. The first rotating part 301 is rotationally connected with the rotating rod 2 through the first rotating shaft 303 to facilitate the folding operation of the dustpan. The second rotating part 302 is circumferentially rotationally connected with the dustpan bin 1 to facilitate the rotating operation of the rotating rod 2 along its circumferential direction, so as to change the orientation of the first rotating shaft 303, thereby realizing the locking and unlocking of the locking assembly 3.

[0218] Specifically, in the dustpan state shown in FIG. 1A, the axis direction of the first rotating shaft 303 is not perpendicular to the length direction of the dustpan bin 1 (the axis direction of the first rotating shaft 303 is parallel to the length direction of the dustpan bin 1 in some embodiments), so when the user applies a force to the length direction of the dustpan bin 1 to try to flatten the dustpan along the 101, the position of the first rotating shaft 303 will interfere with the relative rotation of the rotating rod 2 and the first rotating part 301, thereby realizing the locking function of the locking assembly 3 and ensuring that the dustpan cannot be folded by mistake. Figure 2 Figure 2 In the dustpan state shown in FIG. 1A, the axis direction of the first rotating shaft 303 is not perpendicular to the length direction of the dustpan bin 1 (the axis direction of the first rotating shaft 303 is parallel to the length direction of the dustpan bin 1 in some embodiments), so when the user applies a force to the length direction of the dustpan bin 1 to try to flatten the dustpan along the 101, the position of the first rotating shaft 303 will interfere with the relative rotation of the rotating rod 2 and the first rotating part 301, thereby realizing the locking function of the locking assembly 3 and ensuring that the dustpan cannot be folded by mistake. Figure 3

[0219] It should be noted that the rotating rod 2 can be arranged to approach or move away from the dustpan along the 101, and the dustpan can be in a folded state. When the rotating rod 2 is folded to approach the dustpan along the 101, the rotating rod 2 is folded towards the front of the dustpan bin 1. When the rotating rod 2 is folded to move away from the dustpan along the 101, the rotating rod 2 is folded towards the rear of the dustpan bin 1.

[0220] In some embodiments, as shown in FIG. 1B, the dustpan bin 1 is provided with a mounting groove 102, and the second rotating part 302 is inserted into the mounting groove 102 to rotationally connect the second rotating part 302 with the dustpan bin 1. Figure 5 Figure 7 Figure 8 In the above embodiment, the dustpan bin 1 is provided with the mounting groove 102, so that the second rotating part 302 of the locking assembly 3 is inserted into the mounting groove 102 for rotationally mounted, which is simple in structure and reliable in connection.

[0221] Specifically, when the second rotating part 302 is inserted into the mounting groove 102, the outer wall of the second rotating part 302 is gap-fitted with the inner wall of the mounting groove 102, thereby realizing the circumferential rotational connection between the second rotating part 302 and the dustpan bin 1.

[0222] Specifically, when the second rotating part 302 is inserted into the mounting groove 102, the outer wall of the second rotating part 302 is gap-fitted with the inner wall of the mounting groove 102, thereby realizing the circumferential rotational connection between the second rotating part 302 and the dustpan bin 1.

[0223] ​​​​It should be noted that the installation groove 102 can be a through groove penetrating the height direction of the dustpan hopper 1, or a groove opened on the upper surface of the dustpan hopper 1, and the embodiment is not limited.

[0224] In some embodiments, as shown in Figure 5 、 Figure 7 、 Figure 8 The second rotating part 302 and one of the installation grooves 102 are provided with an annular clamping groove 3021, and the other is provided with a buckle 1021; the second rotating part 302 is inserted into the installation groove 102, so that the buckle 1021 is clamped and matched with the annular clamping groove 3021, and the annular clamping groove 3021 can rotate circumferentially relative to the buckle 1021.

[0225] In the above embodiment, the circumferential rotation matching of the second rotating part 302 and the installation groove 102 is realized through the clamping and matching of the annular clamping groove 3021 and the buckle 1021, which is simple in structure and reliable in connection.

[0226] Specifically, in the embodiment, the outer wall of the second rotating part 302 is provided with the annular clamping groove 3021, and the inner wall or the bottom of the installation groove 102 is provided with the buckle 1021. The annular clamping groove 3021 is arranged along the whole circumference of the outer wall of the second rotating part 302, and the buckle 1021 is provided with a plurality of buckles and is distributed along the inner wall or the bottom of the installation groove 102 in a circumferential direction.

[0227] In some embodiments, as shown in Figure 5 、 Figure 7 、 Figure 8 The installation groove 102 is a through groove, and when the second rotating part 302 is inserted into the installation groove 102, the buckle 1021 is communicated with the outside through the bottom of the through groove, so as to facilitate the adjustment of the matching between the buckle 1021 and the annular clamping groove 3021.

[0228] In the above embodiment, the installation groove 102 is a through groove to facilitate the user to directly adjust the matching between the buckle 1021 and the annular clamping groove 3021 through the bottom of the dustpan hopper 1, thereby facilitating the disassembly and assembly of the rotating rod 2.

[0229] Specifically, the installation groove 102 is a through groove, and the bottom of the installation groove 102 is provided with the buckle 1021, so that the position of the buckle 1021 is located at the bottom of the dustpan hopper 1, thereby facilitating the user to adjust the buckle 1021.

[0230] In some embodiments, as shown in Figure 5 A one-way limiting mechanism is arranged between the second rotating part 302 and the installation groove 102, so that the second rotating part 302 can rotate in one direction relative to the dustpan hopper 1.

[0231] In the above embodiment, the one-way limiting mechanism is arranged between the second rotating part 302 and the mounting groove 102 to control the second rotating part 302 to rotate in one direction only relative to the dustpan 1, avoiding excessive wear of the inner wall of the mounting groove 102 when the second rotating part 302 is driven to rotate.

[0232] Specifically, the one-way limiting mechanism can be designed as an electronic lock or a combination of a ratchet and a one-way groove.

[0233] In some embodiments, as shown in Figure 5 , Figure 8 , Figure 9 , Figure 10 The one-way limiting mechanism includes at least one one-way groove 1022 and at least one limiting ratchet 3022 that cooperate with each other, one of which is arranged on the outer wall of the second rotating part 302, and the other is arranged on the inner wall of the mounting groove 102. The second rotating part 302 is connected through the clamping cooperation of the at least one one-way groove 1022 and the at least one limiting ratchet 3022, thereby rotating in one direction relative to the dustpan 1.

[0234] In the above embodiment, the one-way rotating cooperation structure of the one-way groove 1022 and the limiting ratchet 3022 realizes the one-way rotating cooperation between the second rotating part 302 and the mounting groove 102, which is simple in structure and reliable in connection.

[0235] Specifically, in the present embodiment, the limiting ratchet 3022 is arranged on the outer wall of the second rotating part 302, and the one-way groove 1022 is arranged on the inner wall of the mounting groove 102.

[0236] Further, the limiting ratchet 3022 is arranged in two along the outer wall of the second rotating part 302, and the one-way groove 1022 is arranged in four along the inner wall of the mounting groove 102.

[0237] In some embodiments, as shown in Figure 5 , Figure 6 A limiting assembly is arranged between the first rotating part 301 and the rotating rod 2, which can limit the rotation of the rotating rod 2 along the first rotating shaft 303 relative to the first rotating part 301, so as to fix the position of the rotating rod 2 relative to the dustpan 1.

[0238] In the above embodiment, the limiting assembly is arranged between the first rotating part 301 and the rotating rod 2, so as to keep the dustpan in the folded position or in the working position, thereby improving the stability.

[0239] Specifically, the limiting assembly can be designed as an electronic lock or a combination of a protrusion and a groove.

[0240] In some embodiments, as shown in Figure 5 , Figure 6、 Figure 11 The limiting assembly includes a plurality of grooves 3011 and a limiting protrusion 201.

[0241] The plurality of grooves 3011 are distributed on the first rotating part 301 along the circumference of the first rotating shaft 303; the limiting protrusion 201 is arranged on the rotating rod 2 and can be matched with the grooves 3011; after the rotating rod 2 rotates relative to the first rotating part 301, the limiting protrusion 201 can be matched with one of the grooves 3011 to fix the position of the rotating rod 2 relative to the dustpan hopper 1.

[0242] In the above embodiment, the position of the rotating rod 2 relative to the first rotating part 301 is fixed by the matching of the plurality of grooves 3011 and the limiting protrusion 201, so as to keep the dustpan in the folded position or in the working position, which has a simple structure and reliable connection.

[0243] Specifically, in the embodiment, one limiting protrusion 201 is arranged at the middle position of the rotating rod 2, and a plurality of grooves 3011 are arranged at the outer periphery of the upper position of the first rotating part 301 at intervals, and the limiting protrusion 201 can be matched with at least one of the grooves 3011 after the rotating rod 2 rotates.

[0244] Further, three grooves 3011 are arranged at the outer periphery of the top of the first rotating part 301 at intervals, and the three grooves 3011 are distributed at an angle of 90° relative to the first rotating shaft 303 and are respectively located at the top position and the two side positions of the first rotating part 301.

[0245] Further, the limiting protrusion 201 can exert force on the grooves 3011 by friction or elastic deformation, so as to keep the position of the rotating rod 2 relative to the first rotating part 301 fixed.

[0246] In some embodiments, as shown in Figure 11 The limiting protrusion 201 is arranged as an elastic sheet protruding towards the grooves 3011, or the limiting protrusion 201 includes an elastic assembly.

[0247] In the above embodiment, the limiting protrusion 201 is arranged as an elastic sheet or an elastic assembly to exert force on the grooves 3011 by elastic deformation, so as to ensure the stability of the deformation and resetting of the limiting protrusion 201.

[0248] Specifically, in the embodiment, the limiting protrusion 201 is arranged as an elastic sheet.

[0249] In some embodiments, as shown in Figure 1 The dustpan further includes a dustpan rod 5 connected to one end of the rotating rod 2 away from the dustpan hopper 1.

[0250] In the above embodiment, the dustpan rod 5 is connected to the rotating rod 2 as an extension to facilitate user use.

[0251] In some embodiments, as shown in Figure 1 The dustpan rod 5 and the rotating rod 2 are integrally formed or detachably connected; or, the rotating rod 2 is sleeved outside at least part of the dustpan rod 5.

[0252] In the above embodiments, the dustpan rod 5 and the rotating rod 2 are integrally formed to improve the structural stability of the dustpan; the dustpan rod 5 and the rotating rod 2 are detachably connected to facilitate the factory packaging and transportation of the dustpan.

[0253] In addition, the user can drive the rotating rod 2 to rotate through the dustpan rod 5 to switch the locking assembly 3 between the unlocked state and the locked state, so that the user uses more conveniently. Specifically, when it is needed to switch the locking assembly 3 between the unlocked state and the locked state, the user can rotate the dustpan rod 5 circumferentially, the dustpan rod 5 drives the rotating rod 2 to rotate circumferentially, and the rotating rod 2 drives the locking assembly 3 to rotate circumferentially to switch between the unlocked state and the locked state.

[0254] Specifically, the rotating rod 2 can be sleeved outside at least part of the dustpan rod 5, or at least part of the dustpan rod 5 is sleeved outside the rotating rod 2.

[0255] In some embodiments, as shown in Figure 1 The dustpan rod 5 is provided as a multi-segment rod body, and adjacent two rod bodies are threadedly connected; when the one-way limiting mechanism is provided between the second rotating part 302 and the mounting groove 102, the direction in which the second rotating part 302 can rotate relative to the dustpan hopper 1 unidirectionally is the same as the thread connection direction between the rod bodies.

[0256] In the above embodiments, the direction in which the second rotating part 302 can rotate relative to the dustpan hopper 1 unidirectionally is the same as the thread connection direction between the rod bodies, so as to avoid that the second rotating part 302 causes the multi-segment rod body of the dustpan rod 5 to loosen when the rotating rod 2 and the dustpan rod 5 are rotated, and to ensure the structural stability of the dustpan.

[0257] Specifically, the dustpan rod 5 is provided as a multi-segment rod body to facilitate factory packaging and transportation, the direction in which the second rotating part 302 can rotate relative to the dustpan hopper 1 unidirectionally is the same as the thread connection direction between the rod bodies, and when the rotating rod 2 and the dustpan rod 5 are rotated to drive the second rotating part 302 to rotate, the multi-segment rod body of the dustpan rod 5 will form a tighter thread connection and will not loosen.

[0258] In some embodiments, as shown in Figure 1 When the locking assembly 3 is in the locked state, the rotating rod 2 can be close to the dustpan hopper 1 with the axis of the first rotating shaft 303 as the rotation axis.

[0259] In the above embodiment, when the locking assembly 3 is in the locked state, the rotating rod 2 can be close to the dustpan hopper 1 with the first rotating shaft 303 as the rotation axis, so that the rotating rod 2 can drive the dustpan rod 5 to fold towards the left side or the right side of the dustpan hopper 1.

[0260] Specifically, the rotating rod 2 can be close to the dustpan hopper 1 with the first rotating shaft 303 as the rotation axis, so that the rotating rod 2 can drive the dustpan rod 5 to fold towards the left side or the right side of the dustpan hopper 1. Figure 1 In the view angle, the rotating rod 2 can drive the dustpan rod 5 to fold towards the left side or the right side of the dustpan hopper 1.

[0261] The second embodiment of the dustpan is introduced below.

[0262] In some embodiments, as shown in Figure 12 , Figure 13 The connecting seat 103 is arranged on the dustpan hopper 1, the rotating rod 2 is rotationally connected with the connecting seat 103 through the second rotating shaft 304, the axis direction of the second rotating shaft 304 is perpendicular to the length direction of the dustpan hopper 1, so that the rotating rod 2 is rotationally arranged on the dustpan hopper 1 and can be close to the dustpan along 101 with the second rotating shaft 304 as the rotation axis, so that the dustpan is in the folded state; at least part of the locking assembly 3 is arranged in the interior of the rotating rod 2, and can rotate circumferentially relative to the rotating rod 2, so that the locking assembly 3 is switched between the unlocked state and the locked state; when the locking assembly 3 is in the locked state, the locking assembly 3 cooperates with the connecting seat 103; when the locking assembly 3 is in the unlocked state, the locking assembly 3 is disengaged from the connecting seat 103.

[0263] In the above embodiment, the connecting seat 103 is arranged on the dustpan hopper 1, the rotating rod 2 is rotationally connected with the connecting seat 103 through the second rotating shaft 304, so as to facilitate the folding operation of the dustpan; at least part of the locking assembly 3 is arranged in the interior of the rotating rod 2, and the locking assembly 3 is switched between the unlocked state and the locked state by rotating circumferentially relative to the rotating rod 2; and the locking assembly 3 in the locked state cooperates with the connecting seat 103 to fix the position of the rotating rod 2, so as to facilitate the dustpan to keep the working state; and the locking assembly 3 in the unlocked state is disengaged from the connecting seat 103 to realize the free movement of the rotating rod 2, so as to facilitate the folding of the dustpan.

[0264] Specifically, the locking assembly 3 can cooperate with the inner wall of the connecting seat 103 to fix the position of the rotating rod 2.

[0265] In some embodiments, as shown in Figure 12 , Figure 13As shown, the locking assembly 3 comprises a locking rod 305 and a locking piece 306 arranged on the locking rod 305, part of the locking rod 305 is sleeved in the rotating rod 2, and the locking piece 306 extends out of the rotating rod 2; when the locking rod 305 rotates relative to the rotating rod 2, the locking piece 306 is driven to rotate synchronously; the connecting seat 103 is provided with a matching part 1034 matched with the locking piece 306; when the locking assembly 3 is in the locked state, the locking piece 306 and the matching part 1034 are matched; when the locking assembly 3 is in the unlocked state, the locking piece 306 and the matching part 1034 are separated.

[0266] In the above embodiment, the locking piece 306 on the locking assembly 3 extending out of the rotating rod 2 is matched or separated with the matching part 1034 arranged on the connecting seat 103, so as to realize the switching of the locked state or the unlocked state of the locking assembly 3.

[0267] Specifically, the locking piece 306 is arranged at the bottom of the locking rod 305 or the side wall position close to the bottom of the locking rod 305, so as to facilitate the matching or separation of the locking piece 306 and the matching part 1034 arranged on the connecting seat 103.

[0268] In some embodiments, the locking piece 306 and the matching part 1034 constitute a first electronic lock.

[0269] In the above embodiment, the first electronic lock is used to control the matching and separation of the locking piece 306 and the matching part 1034, so as to realize the convenient and fast electric control.

[0270] Specifically, the first electronic lock is an electric capacitor lock or an electric voltage lock.

[0271] In some embodiments, as shown in Figure 12 , Figure 13 The locking piece 306 is a limiting block 3061 arranged on the locking rod 305, and the matching part 1034 is a first side wall 1031 of the connecting seat 103; when the locking assembly 3 is in the locked state, the limiting block 3061 abuts against the first side wall 1031 of the connecting seat 103; when the locking assembly 3 is in the unlocked state, the limiting block 3061 is separated from the first side wall 1031 of the connecting seat 103.

[0272] In the above embodiment, the limiting block 3061 on the locking assembly 3 extending out of the rotating rod 2 is matched or separated with the first side wall 1031 arranged on the connecting seat 103, so as to realize the switching of the locked state or the unlocked state of the locking assembly 3.

[0273] Specifically, the limiting block 3061 protrudes from the surface of the locking piece 306, and the protrusion of the limiting block 3061 enables the limiting block 3061 to abut against the first side wall 1031 of the connecting seat 103, so as to realize the locking of the locking assembly 3 and limit the rotation of the rotating rod 2; meanwhile, when the limiting block 3061 is driven to rotate away from the first side wall 1031, the locking assembly 3 is unlocked, and the rotating rod 2 can rotate freely.

[0274] In some embodiments, the side wall of the rotating rod 2 is provided with a first opening in the circumferential direction, and the locking piece 306 extends out of the rotating rod 2 from the first opening, so as to cooperate with the matching part 1034.

[0275] In the above-mentioned embodiments, the side wall of the rotating rod 2 is provided with a first opening in the circumferential direction, so that the locking piece 306 extends out of the rotating rod 2 from the side of the rotating rod 2, and the limiting block 3061 on the locking piece 306 cooperates with the first side wall 1031 of the connecting seat 103.

[0276] Specifically, a plurality of spaced transverse strip-shaped grooves are formed in the circumferential direction of the side wall of the rotating rod 2, so that the limiting block 3061 on the locking piece 306 extends out of the rotating rod 2.

[0277] In some embodiments, as shown in Figure 12 、 Figure 13 , a second opening is formed in the bottom of the rotating rod 2, and the locking piece 306 extends out of the rotating rod 2 from the second opening, so as to cooperate with the matching part 1034.

[0278] In the above-mentioned embodiments, a second opening is formed in the bottom of the rotating rod 2, so that the locking piece 306 extends out of the rotating rod 2 from the bottom of the rotating rod 2, and the limiting block 3061 on the locking piece 306 cooperates with the first side wall 1031 of the connecting seat 103.

[0279] Specifically, the locking rod 305 penetrates through the rotating rod 2, so that the limiting block 3061 on the locking piece 306 extends out of the rotating rod 2 from the second opening in the bottom of the rotating rod 2.

[0280] In some embodiments, as shown in Figure 12 、 Figure 13 , the bottom of the locking rod 305 is provided with a limiting protrusion 3051, and the limiting protrusion 3051 is arranged opposite to the rotating rod 2, so as to limit the movement of the locking rod 305 to the top of the rotating rod 2.

[0281] In the above-mentioned embodiments, by arranging the limiting protrusion 3051 to limit the cooperation with the rotating rod 2, the movement of the locking rod 305 to the top of the rotating rod 2 is avoided, and the stability of the dustpan is ensured.

[0282] Specifically, the limiting protrusion 3051 is arranged along the entire circumference of the locking rod 305, and is arranged to protrude transversely outward relative to the locking rod 305.

[0283] In some embodiments, as shown in Figure 12 、 Figure 13 、 Figure 14 The locking assembly 3 further comprises a limiting device which is capable of limiting the circumferential rotation of the locking piece 306 relative to the rotating rod 2.

[0284] In the above embodiments, the limiting device is used to limit the circumferential rotation of the locking piece 306 relative to the rotating rod 2, so as to avoid the dustpan being folded incorrectly.

[0285] In some embodiments, the limiting device is a second electronic lock.

[0286] In the above embodiments, the second electronic lock is used to control the circumferential rotation of the locking piece 306 relative to the rotating rod 2, so as to achieve convenient and fast electric control.

[0287] Specifically, the second electronic lock is a capacitive lock or a voltage lock.

[0288] In some embodiments, as shown in Figure 12 、 Figure 13 、 Figure 14 The limiting device is a spring block 104 arranged on the connecting seat 103, which is capable of abutting against the locking piece 306, so as to make the locking piece 306 axially abut against the rotating rod 2, thereby limiting the circumferential rotation of the locking piece 306 relative to the rotating rod 2.

[0289] In the above embodiments, the static friction force generated by the spring block 104 abutting against the locking piece 306 is used to limit the circumferential rotation of the locking piece 306 relative to the rotating rod 2.

[0290] Specifically, the spring force generated by the spring block 104 is directed upwardly towards the locking piece 306, so as to exert a vertically upward force on the locking piece 306 by the spring force generated by the spring block 104, thereby making the spring block 104 tightly abut against the bottom of the locking piece 306, and generating a larger static friction force to overcome the rotating force received by the locking piece 306.

[0291] In some embodiments, as shown in Figure 12 、 Figure 13 、 Figure 14 The outer wall of the rotating rod 2 is provided with a recessed groove 202, and the spring block 104 is capable of abutting against the recessed groove 202 when the dustpan is in the folded state, so as to fix and keep the dustpan in the folded state.

[0292] In the above embodiments, the recessed groove 202 of the outer wall of the rotating rod 2 is used to engage with the spring block 104 when the dustpan is folded, so as to keep the dustpan fixed in the folded state, thereby ensuring the structural stability of the dustpan in the storage state.

[0293] Specifically, the rotating rod 2 is rotated downward until the dustpan is in the folded state, at which time the elastic block 104 exerts an upward force on the rotating rod 2, which causes the rotating rod 2 to interfere with the second rotating shaft 304 and the connecting seat 103 to a certain extent, thereby being able to limit the rotating rod 2 to return to the original position.

[0294] In some embodiments, as shown in Figure 14 , the elastic block 104 includes a spring 1041 abutting against the connecting seat 103 and extending towards the locking piece 306, and an elastic block head 1042 provided on the top of the spring 1041, which is capable of abutting against the locking piece 306.

[0295] In the above embodiment, the spring 1041 connected with the elastic block head 1042 is provided to facilitate the elastic block head 1042 to exert a restoring elastic force by the spring 1041.

[0296] Specifically, the top of the elastic block head 1042 can be shaped according to the recessed groove 202 to improve the stability of the elastic block 104 limiting the rotating rod 2.

[0297] In some embodiments, the limiting device further includes a clamping mechanism provided between the rotating rod 2 and the locking rod 305, and when the locking rod 305 moves along the axial direction of the rotating rod 2 and moves towards the dustpan 1 relative to the rotating rod 2, the clamping mechanism is in a separated state, so that the locking rod 305 can rotate circumferentially relative to the rotating rod 2.

[0298] In the above embodiment, the clamping mechanism is provided to enable the locking rod 305 to rotate circumferentially relative to the rotating rod 2.

[0299] In some embodiments, as shown in Figure 12 , Figure 15 , Figure 16 , Figure 17 , Figure 18 , the clamping mechanism includes a clamping block 3062 and an open slot cooperating with the clamping block 3062, one of the clamping block 3062 and the open slot is provided on the locking piece 306, and the other is provided on the side wall of the rotating rod 2; when the locking rod 305 moves along the axial direction of the rotating rod 2 and moves towards the dustpan 1 relative to the rotating rod 2, the clamping block 3062 can be separated from the open slot, so that the locking rod 305 can rotate relative to the rotating rod 2.

[0300] In the above embodiment, the clamping block 3062 and the open slot are used to limit and separate the position of the clamping block 3062, so as to realize the fixing and rotation of the locking rod 305 relative to the rotating rod 2 by a corresponding angle, so as to adjust the position of the clamping block 3062 and realize the rotation adjustment of the rotating rod 2 relative to the dustpan 1.

[0301] Specifically, in the present embodiment, the clamping block 3062 is provided on the locking piece 306, and the open slot is provided on the side wall of the rotating rod 2.

[0302] In some embodiments, as shown in Figure 12 , Figure 15 , Figure 16 , Figure 17 , Figure 18 The opening slots include first opening slots 203 and second opening slots 204 distributed circumferentially along the rotating rod 2; after the locking rod 305 moves along the axial direction of the rotating rod 2 to the direction close to the dustpan bucket 1, the locking rod 305 can drive the locking piece 306 to move, so that the elastic block 104 is compressed and the clamping block 3062 is separated from the first opening slot 203, so that the clamping block 3062 can be moved to the second opening slot 204 by the rotating movement of the locking rod 305, and the clamping block 3062 is clamped to the second opening slot 204 when the elastic block 104 resets.

[0303] In the above embodiments, the first opening slots 203 and the second opening slots 204 distributed circumferentially along the rotating rod 2 are respectively matched with the clamping block 3062, so as to change the locking state and the unlocking state of the locking assembly 3.

[0304] Specifically, Figure 15 , Figure 16 As shown in the state of the locking rod 305, the clamping block 3062 is clamped on two first opening slots 203 arranged opposite along the length direction of the dustpan bucket 1, at this time, the clamping block 3062 can be used as a limiting block 3061 and abuts against the first side wall 1031 of the connecting seat 103, so as to avoid the rotating rod 2 from being driven to fold, so as to maintain the folding state of the dustpan; Figure 17 , Figure 18 As shown in the state of the locking rod 305, the clamping block 3062 is clamped on two second opening slots 204 arranged opposite along the width direction of the dustpan bucket 1, at this time, the clamping block 3062 is separated from the first side wall 1031 of the connecting seat 103, so that the rotating rod 2 can be driven to rotate to fold the dustpan.

[0305] Further, since the first opening slots 203 and the second opening slots 204 are straight slots, the clamping stability can be improved, but they can only limit the clamping block 3062 and cannot change the depth of the clamping block 3062 matched with the slot body, so that when the locking rod 305 rotates, the clamping block 3062 needs to be separated from the first opening slot 203 or the second opening slot 204 by applying force downward along the axial direction of the rotating rod 2, so that the locking rod 305 can drive the clamping block 3062 to adjust the rotating position.

[0306] In some embodiments, as shown in Figure 13 , Figure 19 , Figure 20 , Figure 21 , Figure 22As shown, the engagement mechanism comprises the clamping block 3062 and the ratchet groove matched with the clamping block 3062, one of which is arranged on the locking member 306 and the other of which is arranged on the side wall of the rotating rod 2; after the locking rod 305 rotates in the circumferential direction, the clamping block 3062 can be separated from the ratchet groove, so that the locking rod 305 can rotate relative to the rotating rod 2.

[0307] In the above embodiment, the limiting cooperation and separation of the clamping block 3062 and the ratchet groove are used to realize the fixation and rotation of the locking rod 305 relative to the rotating rod 2 by a corresponding angle, so as to adjust the position of the clamping block 3062 and realize the rotation adjustment of the rotating rod 2 relative to the dustpan 1. In addition, the cooperation of the clamping block 3062 and the ratchet groove can realize the one-way locking of the locking rod 305 relative to the rotating rod 2, so as to avoid excessive wear between the locking rod 305 and the inner wall of the rotating rod 2 when the locking rod 305 is driven to rotate.

[0308] Specifically, in the embodiment, the clamping block 3062 is arranged on the locking member 306, and the ratchet groove is arranged on the side wall of the rotating rod 2.

[0309] In some embodiments, as shown in Figure 13 , Figure 19 , Figure 20 , Figure 21 , Figure 22 As shown, the ratchet groove at least comprises the first ratchet groove 205 and the second ratchet groove 206 distributed in the circumferential direction of the rotating rod 2; the rotation of the locking rod 305 in the circumferential direction can drive the locking member 306 to rotate, so that the clamping block 3062 rotates along the first ratchet groove 205 and moves downward, and the elastic block 104 is compressed and makes the clamping block 3062 disengage from the first ratchet groove 205, so that the clamping block 3062 can be moved to the second ratchet groove 206 by the rotation of the locking rod 305, and the clamping block 3062 is pushed to be clamped to the second ratchet groove 206 when the elastic block 104 resets.

[0310] In the above embodiment, the first ratchet groove 205 and the second ratchet groove 206 distributed in the circumferential direction of the rotating rod 2 are respectively matched with the clamping block 3062, so as to change the folding state and working state of the dustpan.

[0312] Further, the first ratchet groove 205 and the second ratchet groove 206 are designed to utilize the characteristics of the ratchet groove, so that the locking rod 305 can drive the block 3062 to move when rotating, thereby changing the depth of the block 3062 cooperating with the groove, so that the block 3062 can rotate and act on the guide of the ratchet groove to leave the first ratchet groove 205 or the second ratchet groove 206 when the locking rod 305 rotates, so that the locking rod 305 can drive the block 3062 to adjust the rotating position.

[0313] In some embodiments, as shown in Figure 12 、 Figure 13 When the locking member 306 is a limiting block 3061 provided on the locking rod 305, the block 3062 is the limiting block 3061.

[0314] In the above embodiment, the block 3062 is directly designed as the limiting block 3061, which can simplify the number of structural parts and save product production cost.

[0315] In some embodiments, as shown in Figure 12 、 Figure 13 When the bottom of the locking rod 305 is provided with a limiting protrusion 3051, the locking member 306 is a limiting block 3061 provided on the locking rod 305, and the limiting protrusion 3051 is the limiting block 3061.

[0316] In the above embodiment, the limiting protrusion 3051 is directly designed as the limiting block 3061, which can simplify the number of structural parts and save product production cost.

[0317] Further, the limiting block 3061 can also be the block 3062 and the limiting protrusion 3051 at the same time, thereby further simplifying the number of structural parts and saving product production cost.

[0318] In some embodiments, as shown in Figure 12 、 Figure 13 、 Figure 23 When the connecting seat 103 is provided with a spring block 104, the top of the spring block 104 is provided with a plurality of annularly arranged inclined grooves 1043, and the block 3062 abuts against and clamps the inclined grooves 1043.

[0319] In the above embodiment, a plurality of annularly arranged inclined grooves 1043 are arranged on the top of the spring block 104, and the spring block 104 can be deformed and compressed with the rotation of the block 3062.

[0320] In some embodiments, the dustpan further comprises a dustpan rod 5 connected to the locking assembly 3 at an end away from the dustpan hopper 1.

[0321] In the above embodiments, the dustpan rod 5 is connected to the rotating rod 2 as an extension rod to facilitate user use.

[0324] Specifically, the locking rod 305 can be sleeved on at least part of the outer portion of the dustpan rod 5, or at least part of the dustpan rod 5 is sleeved on the outer portion of the locking rod 305.

[0325] In some embodiments, as shown in Figure 12 , Figure 13 The connecting seat 103 comprises a first side wall 1031, and a second side wall 1032 and a third side wall 1033 connected to and oppositely arranged with the first side wall 1031, the first side wall 1031, the second side wall 1032 and the third side wall 1033 enclose a containing cavity, at least part of the rotating rod 2 is located in the containing cavity, and a cooperation portion 1034 cooperating with the locking piece 306 is provided on the first side wall 1031.

[0338] In some embodiments, as shown in Figure 26 When the locking assembly 3 is in the locked state, the inclination direction of the handle 6 is the length direction of the dustpan bucket 1. Here, the inclination direction of the handle 6 is the direction in which the handle 6 is away from the end of the dustpan rod 5.

[0339] In the above embodiments, when the locking assembly 3 is in the locked state, the inclination direction of the handle 6 is the length direction of the dustpan hopper 1, so as to facilitate the user to hold the handle 6 to use the dustpan. Figure 26 As shown in the figure, the inclination direction of the handle 6 is the rear side of the dustpan hopper 1.

[0340] In some embodiments, when the locking assembly 3 is in the unlocked state, the inclination direction of the handle 6 is the width direction of the dustpan hopper 1. As shown in the figure, the inclination direction of the handle 6 is the left side of the dustpan hopper 2. Figure 25

[0342] Moreover, when the user normally uses the dustpan, the inclination direction of the handle 6 is the length direction of the dustpan hopper 1, and the locking assembly 3 is in the locked state, so as to normally use the dustpan; when the dustpan needs to be stored, the inclination direction of the handle 6 is rotated to the width direction of the dustpan hopper 1, at this time, the locking assembly 3 is just in the unlocked state, thereby storing the dustpan.

[0343] When the user drives the locking assembly 3 to be in the unlocked state and the locked state through the dustpan rod 5, since the handle 6 and the dustpan rod 5 are synchronously rotated, the locking assembly 3 can be driven to be in the unlocked state and the locked state through the handle 6. Moreover, when the storage state of the handle 6, i.e., the inclination direction of the handle 6 is the width direction of the dustpan hopper 1, the locking assembly 3 is just in the unlocked state, i.e., the dustpan hopper 1 can be folded; when the use state of the handle 6, i.e., the inclination direction of the handle 6 is the length direction of the dustpan hopper 1, the locking assembly 3 is just in the locked state, i.e., the dustpan hopper 1 can be normally used, thereby making the user just unlock the locking assembly 3 in the process of storing the handle 6, so as to make the dustpan hopper 1 also be stored.

[0346] ​​Moreover, when the user normally uses the dustpan, the tilting direction of the handle 6 is the length direction of the dustpan hopper 1, the locking assembly 3 is in the locked state, and the dustpan can be normally used; when the dustpan needs to be stored, the tilting direction of the handle 6 is rotated to the width direction of the dustpan hopper 1, at this time, the locking assembly 3 is just in the unlocked state, so that the dustpan is stored.

[0347] When the user drives the unlocking state and the locking state of the locking assembly 5 through the dustpan rod 5, because the handle 6 and the dustpan rod 5 are synchronously rotated, the unlocking state and the locking state of the locking assembly 5 can be driven through the handle 6, and because when the storage state of the handle 6, that is, the tilting direction of the handle 6 is the width direction of the dustpan hopper 1, the locking assembly 5 is just in the unlocked state, that is, the dustpan hopper 1 can be folded; and because the use state of the handle 6, that is, the tilting direction of the handle 6 is the length direction of the dustpan hopper 1, the locking assembly 5 is just in the locked state, that is, the dustpan hopper 1 can be normally used, the user just unlocks the locking assembly 5 in the process of storing the handle 6, so that the dustpan hopper 1 can also be stored.
