Description

Technical Field

[0001] This utility model relates to the field of cleaning vehicles, specifically to a cleaning vehicle with a flexibly adjustable storage compartment. Background Technology

[0002] In recent years, with the continuous improvement of people's quality of life, people have paid more and more attention to the hygiene of their surrounding living environment. However, the cleaning equipment traditionally used in homes, hotels, office buildings and other environments usually consists of only a mop, a bucket and a rag. This requires constant trips to the toilet to change the water and to the garbage cans at a distance to empty and clean the garbage. As a result, the cleaning efficiency of cleaning staff is poor and the labor intensity is high.

[0003] The existing cleaning vehicles are equipped with multiple open storage compartments for storing bottled cleaning and disinfecting solutions and other products. However, the open design presents two major problems: First, the lack of protection during use poses a risk that infants and young children may grab, play with, or even drink the solution; second, long-term exposure to the outside environment is not conducive to the storage of disinfecting solutions. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a cleaning vehicle with a flexibly adjustable storage compartment:

[0005] A cleaning cart with flexibly adjustable storage compartments includes a base with multiple casters movably connected to the bottom of the base for moving the cart. A support frame is connected to the top of the base, and multiple longitudinally arranged storage compartments are arranged inside the support frame. The upper surface of each storage compartment has a storage slot for holding objects. A locking unit is provided between the storage compartment and the support frame to control the movement or locking of the storage compartment relative to the support frame. When one of the storage compartments is in an active state, the bottom surface or storage slot of the storage compartment can fit together with the storage slot of another storage compartment to form a sealed cavity.

[0006] Preferably, the support frame includes two parallel support plates fixedly inserted into the base, wherein one or two support plates are axially arrayed with multiple locking slots, and the side of the storage compartment is provided with a locking tongue that is plugged into and adapted to the locking slots. The locking slots and the locking tongue constitute the locking unit.

[0007] Preferably, the locking groove is a first side sliding groove provided on the corresponding surfaces of the two support plates. The first side sliding groove extends laterally along the support plates. One end of the first side sliding groove is provided with a limiting part, and the other end of the first side sliding groove is connected to a sliding opening. The sliding openings of the two support plates are located on the same side. The locking tongue is a straight protrusion provided on both sides of the storage compartment. The straight protrusion and the locking groove are detachably slidably inserted and fixed through the sliding opening. The straight protrusion and the limiting part form abutment and limiting cooperation.

[0008] Preferably, the corresponding surfaces of the two support plates are provided with an axial first vertical track groove. One side of the first vertical track groove is connected to a plurality of laterally extending second side sliding grooves, which are the locking grooves. The storage compartment is provided with a square protrusion in the middle that is adapted to form a guide rail with the first vertical track groove. The square protrusion is a locking tongue. When the square protrusion is located in the first vertical track groove, the storage compartment can slide up and down relative to the support plate. When the square protrusion slides into the second side sliding groove, the storage compartment and the support plate are mutually locked.

[0009] Preferably, one or more storage compartments are capable of flipping and sliding up and down relative to the support frame. When a storage compartment slides down or flips down, the bottom surface of the storage compartment or the storage slot of the storage compartment forms a sealed cavity with the storage slot of the next adjacent storage compartment. This technical solution can achieve mutual coverage between the bottom surface of the storage compartment and the upper surface of the next storage compartment, or mutual coverage between the storage slot of the storage compartment and the upper surface of the next storage compartment. The latter covering method can further increase the volume of the sealed cavity, thus providing better flexibility and adaptability.

[0010] Preferably, the corresponding surfaces of the two support plates are provided with a central track groove extending vertically along the center of the support plate. Multiple side slots are symmetrically arranged on both sides of the central track groove, and the side slots are the locking slots. The storage compartment has a cylindrical protrusion in the middle that is adapted to the central track groove to form a guide rail. A locking component is provided on one side of the cylindrical protrusion. The locking component includes a lock body and a bolt. The bolt can freely extend and retract relative to the lock body. When the bolt extends and is adapted to the side slot, the storage compartment and the support plate are locked together. When the bolt retracts and is not adapted to the side slot, the storage compartment can rotate relative to the support plate or slide up and down along the central track groove.

[0011] Preferably, the side slot has a sliding opening on the side of the support plate, and the lock body has a sliding cavity for the extension and retraction of the bolt. The bolt includes a tongue body and an integrally connected base plate to the inner end of the tongue body. The tongue body and the opening of the sliding cavity form a sliding fit, and the base plate and the inner wall of the sliding cavity corresponding to the opening form a limiting fit. The tongue body has a T-shaped structure and includes an integrally perpendicular horizontal part and a vertical part. When the side slot and the tongue body are inserted and fitted, the horizontal part of the tongue body is inserted into the side slot. At this time, the side of the vertical part near the horizontal part forms a tight-fitting limiting fit with the side of the support plate. The T-shaped tongue body has better assembly stability than the conventional straight tongue body. Its horizontal part is used for insertion and positioning, while the vertical part, through tight-fitting limiting with the side of the support plate, can further prevent the storage compartment from tipping over.

[0012] Preferably, an elastic reset member is provided between the locking tongue and the bottom surface of the sliding cavity, the tongue body and the side slot form an elastic locking engagement, the inner end of the locking tongue is provided with a mounting groove for accommodating the elastic reset member, one end of the elastic reset member abuts against the bottom surface of the mounting groove, and the other end abuts against the inner wall of the sliding cavity.

[0013] Preferably, a lever is radially fixedly connected to the side of the latch, and the lever and the sliding opening provided in the lock body form a limiting fit, so that the user can control the extension and retraction of the latch by moving the lever.

[0014] Preferably, a thrust frame is provided on one side of the upper end of the support frame. The thrust frame includes a horizontal plate and a U-shaped support rib. The horizontal plate is connected to the upper end of the support frame, the lower end of the U-shaped support rib is connected to the upper part of the support frame, and the upper end of the U-shaped support rib is connected to the lower end of the horizontal plate. The support plate, the horizontal plate, and the U-shaped support rib form a triangular support structure. A storage box is provided on the other side of the upper end of the support frame.

[0015] Beneficial effects: In practical applications, both the storage compartments and the base of this product can be used to store cleaning tools. When a sealed space is needed, the height of the storage compartments can be adjusted to allow adjacent compartments to overlap, creating a sealed space and preventing direct external grabbing. Furthermore, the height of each storage compartment relative to the support frame is adjustable, greatly improving flexibility. Attached Figure Description

The storage compartment 4 is provided with a square protrusion 10 in the middle that is adapted to the guide rail of the first vertical track groove 8. The square protrusion 10 is a locking tongue. When the square protrusion 10 is located in the first vertical track groove 8, the storage compartment 4 can slide up and down relative to the support plate 3. When the square protrusion 10 slides into the second side slide groove 9, the storage compartment 4 and the support plate 3 are mutually locked.

[0037] Example 3: As Figure 7-12 As shown, a cleaning cart with flexibly adjustable storage compartments includes a base 1. Multiple casters 2 for moving the cleaning cart are movably connected to the bottom of the base 1. A support frame is connected to the top of the base 1, and multiple longitudinally arranged storage compartments 4 are arranged within the support frame. A push frame is provided on one side of the upper end of the support frame. The push frame includes a horizontal plate 20 and a U-shaped support rib 21. The horizontal plate 20 is connected to the upper end of the support frame, and the lower end of the U-shaped support rib 21 is connected to the upper part of the support frame. The upper end of the U-shaped support rib 21 is connected to the lower end of the horizontal plate 20. The support plate 3, the horizontal plate 20, and the U-shaped support rib 21 form a triangular support structure. A storage box 22 is provided on the other side of the upper end of the support frame.

[0038] The upper surface of the storage compartment 4 is provided with a storage slot 5 for holding objects. A locking unit is provided between the storage compartment 4 and the support frame. The locking unit is used to control the movement or locking of the storage compartment 4 relative to the support frame. When one of the storage compartments 4 is in an active state, the bottom surface or storage slot 5 of the storage compartment 4 can fit with the storage slot 5 of the other storage compartment 4 to form a sealed cavity. The support frame includes two parallel support plates 3 fixedly inserted into the base 1. The two support plates 3 are axially arrayed with multiple locking slots. The side of the storage compartment 4 is provided with a locking tongue that fits into the locking slot. The locking slot and the locking tongue constitute the locking unit.

[0039] Multiple storage compartments 4 are capable of flipping and sliding up and down relative to the support frame. When a storage compartment 4 slides down or flips down, the bottom surface of the storage compartment 4 or the storage slot 5 of the storage compartment 4 and the storage slot 5 of the next adjacent storage compartment 4 form a sealed cavity. This technical solution can achieve mutual covering between the bottom surface of the storage compartment 4 and the upper surface of the next storage compartment 4, or mutual covering between the storage slot 5 of the storage compartment 4 and the upper surface of the next storage compartment 4. The latter covering method can further increase the volume of the sealed cavity, thus providing better flexibility and adaptability.

[0040] The two support plates 3 have corresponding surfaces with a central track groove 11 extending vertically along the center of the support plate 3. Multiple side slots 12 are symmetrically arranged on both sides of the central track groove 11. The side slots 12 are the locking slots. The storage compartment 4 has a cylindrical protrusion 13 in the middle that is adapted to the central track groove 11 as a guide rail. A locking assembly is provided on one side of the cylindrical protrusion 13. The locking assembly includes a lock body 14 and a lock tongue. The lock tongue can freely extend and retract relative to the lock body 14. When the lock tongue extends and is adapted to the side slot 12, the storage compartment 4 and the support plate 3 are locked together. When the lock tongue retracts and is not adapted to the side slot 12, the storage compartment 4 can rotate relative to the support plate 3 or slide up and down along the central track groove 11.

[0041] The side slot 12 has a sliding opening on the side of the support plate 3. The lock body 14 has a sliding cavity for the extension and retraction of the bolt. The bolt includes a tongue body 15 and a base plate 16 integrally connected to the inner end of the tongue body 15. The tongue body 15 and the opening of the sliding cavity are slidably adapted. The base plate 16 and the inner wall of the sliding cavity corresponding to the opening are mutually limiting. The tongue body 15 has a T-shaped structure and includes an integrally perpendicular horizontal part and a vertical part. When the side slot 12 and the tongue body 15 are inserted and adapted, the horizontal part of the tongue body 15 is inserted into the side slot 12. At this time, the side of the vertical part near the horizontal part is tightly fitted and limitingly fitted with the side of the support plate 3. An elastic return member 17 is provided between the bolt and the bottom surface of the sliding cavity. The elastic return member 17 used in embodiment 3 is a spring. The tongue 15 and the side slot 12 form an elastic locking engagement. The inner end of the locking tongue is provided with a mounting groove for accommodating the elastic reset member 17. One end of the elastic reset member 17 abuts against the bottom surface of the mounting groove, and the other end abuts against the inner wall of the sliding cavity.

[0042] Operating principle: This application utilizes a locking tongue that, when pressed, overcomes the elastic force of the spring and retracts inward, thereby unlocking the storage compartment 4 from the support plate 3. At this point, the storage compartment 4 can rotate relative to the support plate 3 around the cylindrical protrusion 13 and slide down the vertical track groove to close onto the lower storage compartment 4. This application can employ methods such as... Figure 7 The flip-top closing method shown can also be used Figure 8 As shown in the closing method, after the lid is properly fitted, the tongue 15 of the storage compartment 4 and the side slot 12 are locked together. The structure of this application can also be used for flexible height adjustment of the storage compartment 4. The tongue 15 of this embodiment can be in the form of a straight line or a T-shape, but the T-shape structure has better assembly stability.

[0043] Example 4: Figure 13 As shown, compared to Embodiment 3, Embodiment 4 omits the spring structure, and a lever 18 is radially fixedly connected to the side of the latch. The lever 18 and the sliding groove 19 provided on the lock body 14 form a limiting engagement, allowing the user to control the extension and retraction of the latch by moving the lever 18. In practice, Embodiment 4 can either use a spring structure or omit the spring structure.

[0044] Obviously, the above embodiments of this utility model are merely illustrative examples and not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
