Description

Technical Field

[0001] This utility model belongs to the technical field of floor cleaning tools, specifically relating to a stable flat mop holder and a flat mop. Background Technology

[0002] Flat-push mops, with their advantages of large contact area and simple structure, are increasingly used in various cleaning areas, especially large venues, where they greatly improve cleaning efficiency and require less effort as the mop is propelled forward. Most flat-push mops feature a mop head with a cleaning cloth mounted on the mop holder. Existing mop holders typically have two opposing slots on the bottom wall of the base, with a steel bar bent into a ring-shaped frame. The two long sides of this frame are then engaged in the slots, similar to the limiting groove structure described in CN213721790U. While this structure is simple and quick to install, the steel bar frame is prone to detaching from the slots and separating from the base under impact or other external forces, significantly reducing the user experience. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a stable flat-push mop and a flat-push mop, wherein the base can enclose the support rod in a closed manner to prevent it from falling off.

[0004] The technical solution adopted by this utility model to solve its technical problem is: designing a stable flat-push trailer, including a base, characterized in that: it also includes a cap, the base has two parallel through holes, the peripheral wall of the through holes has a closed section, a support rod is inserted in the through holes, the cap has two insertion holes on the inner end wall, and the free end of the support rod is inserted into the insertion hole.

[0005] Preferably, the base has a first groove on its bottom wall, and a first reinforcing rib is provided in the first groove. The front end of the first reinforcing rib is connected to the front wall of the groove, and the rear end is connected to the rear wall of the groove.

[0006] Preferably, the first groove is provided with a second reinforcing rib, which is arranged in a cross shape with the first reinforcing rib.

[0007] Preferably, a hollow hole is formed on the peripheral wall of the through hole, one end of which is connected to the through hole and the other end is connected to the top or bottom wall of the base.

[0008] Preferably, the end wall of the end cap located on the outer side has a smooth transition from back to front.

[0009] Preferably, a second groove is provided on the bottom wall of the end cap, and a third reinforcing rib is provided in the second groove, with both ends of the third reinforcing rib connected to the side wall of the second groove.

[0010] Preferably, it also includes a limiting rod, with slots at both ends of the limiting rod. The distance between the two slots is adapted to the distance between the two through holes, and the support rod can be locked in the slots.

[0011] Preferably, a first connector is hinged to the top wall of the base, the first connector can rotate along the axial direction of the support rod, and a second connector is also hinged to the first connector, the second connector can rotate along the radial direction of the support rod, and a mop handle mounting hole is provided on the second connector.

[0012] Preferably, the support rod is a rust-free tube, and the base and end cap are injection molded parts.

[0013] This utility model also provides a flat mop, including a mop frame, characterized in that: the mop frame used is the above-mentioned stable flat mop frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. Because the base has two parallel through holes with closed sections on the periphery of the through holes, and a support rod is inserted into the through holes, and the end cap has two insertion holes on the inner end wall, the free end of the support rod is inserted into the insertion holes. This changes the installation structure of the bracket, allowing the base to completely enclose the support rod, improving the stability of the support rod in the base and avoiding the drawback of detachment in the prior art.

[0015] 2. Because the base has a first groove on its bottom wall, the amount of material used in the base can be reduced, thus reducing weight and cost. The first groove has a first reinforcing rib, with the front end of the first reinforcing rib connected to the front wall of the groove and the rear end connected to the rear wall of the groove. This can maintain the strength of the base as much as possible while reducing the amount of material used.

[0016] 3. Since a second reinforcing rib is also provided in the first groove, and the second reinforcing rib is arranged in a cross shape with the first reinforcing rib, the strength of the base can be further improved, which helps to extend its service life.

[0017] 4. Because the peripheral wall of the through hole has a hollow hole, one end of the hollow hole connects to the through hole and the other end connects to the top or bottom wall of the base, the amount of material used in the base can be further reduced without affecting the installation strength of the support rod.

[0018] 5. Because the outer end wall of the end cap has a smooth transition from back to front, the outer end of the end cap is arc-shaped. When it encounters an obstruction from a foreign object, it can be smoothly moved away by the arc, thereby reducing sharp collisions between the two. This not only protects against foreign objects but also extends the service life of the trailer.

[0019] 6. Because a second groove is provided on the bottom wall of the end cap, and a third reinforcing rib is provided in the second groove, the two ends of the third reinforcing rib are connected to the side wall of the second groove. Similar to the base, this also reduces the amount of material used in the end cap while maintaining its strength.

[0020] 7. Since the limiting rod has slots at both ends, and the distance between the two slots is adapted to the distance between the two through holes, the support rod can be locked in the slots. The limiting rod can be locked on the support rod inside the end cap, and the relative position of the support rod installed on the base can be further regulated. On the one hand, it enhances the stability of the support rod installation, and on the other hand, it facilitates the installation of the end cap.

[0021] 8. Because a first connector is hinged to the top wall of the base, the first connector can rotate along the axial direction of the support rod. A second connector is also hinged to the first connector, and the second connector can rotate along the radial direction of the support rod. The second connector has a mop handle mounting hole, which allows the mop handle to rotate omnidirectionally within the hemisphere above the base, making cleaning convenient.

[0022] 9. Because the support rods are made of rust-free tubing such as aluminum, aluminum alloy, or stainless steel, and the base and end caps are made of injection molded parts, the trolley does not rust, avoiding corrosion when placed inside a damp cloth cover. This not only avoids contaminating the cleaning cloth but also extends its service life.

[0023] 10. This utility model has an ingenious design, which changes the installation structure of the trailer and avoids the problem of the metal frame separating from the base in the prior art, making it more convenient to use and easier to promote and apply in the industry.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] When the present invention is in use, the end away from the ground is defined as the top or upper end, and the other end closer to the ground is defined as the bottom or lower end; the side with the center of the trailer in the horizontal direction is defined as the inner side, and the other side away from the center of the trailer is defined as the outer side; when the present invention is in the flat-push state, the side closer to the human body is defined as the rear side, and the other side away from the human body is defined as the front side.

[0028] like Figure 3 As shown, this utility model has two parallel through holes 6 in the base 1. The peripheral wall of the through hole 6 has a closed section, that is, the peripheral wall of the through hole 6 is a closed ring in the radial section. A support rod 2 is inserted into the through hole 6. The end cap 4 has two insertion holes 12 on its inner end wall. The free end of the support rod 2 is inserted into the insertion hole 12. In this way, the existing ring-shaped steel frame is designed as a separate assembly structure of support rod 2 and end cap 4, which changes the installation structure of the bracket. This allows the through hole 6 to achieve a closed wrapping of the support rod 2, so that it will not fall off from the base 1 under the squeezing and impact of external forces. At the same time, although the end cap 4 is inserted into the support rod 2, due to the change of insertion direction, the end cap 4 makes the support rod 2 inserted deeper under the squeezing and impact, and the installation is more secure. Specifically, the support rod 2 can be designed as a closed "U" shape, so only one end cap 4 needs to be installed; or it can be a straight rod with two oppositely arranged end caps 4, as long as the support rod 2 can be inserted into the through hole 6. Figure 4 and Figure 6 As shown, slots 11 are also provided at both ends of the limiting rod 3. The distance between the two slots 11 is adapted to the distance between the two through holes 6. The support rod 2 can be locked in the slots 11. By locking the limiting rod 3 on the support rod 2 that has passed through the through hole 6, the limiting rod 3 is located inside the end cap 4. The relative position of the support rod 2 installed on the base 1 is further regulated. On the one hand, the stability of the support rod 2 installation is enhanced, and on the other hand, the installation of the end cap 4 is facilitated.

[0029] In order to reduce the amount of material used in base 1 while maintaining its original strength as much as possible, such as Figure 5As shown, this utility model has a first groove 15 on the bottom wall of the base 1, and a first reinforcing rib 20 inside the first groove 15. The front end of the first reinforcing rib 20 is connected to the front wall of the groove, and the rear end is connected to the rear wall of the groove. A second reinforcing rib 16 is also provided inside the first groove 15, and the second reinforcing rib 16 is arranged in a cross shape with the first reinforcing rib 20. Similarly, a second groove 21 is provided on the bottom wall of the end cap 4, and a third reinforcing rib 22 is provided in the second groove 21. The two ends of the third reinforcing rib 22 are connected to the side wall of the second groove 21. In this way, the material usage of the base 1 and the end cap 4 is reduced by the structure of the first groove 15 and the second groove 21, and then the reinforcing ribs are used for reinforcement. A plurality of hollow holes 5 are also provided on the peripheral wall of the through hole 6. The plurality of hollow holes 5 are arranged sequentially along the axial direction of the through hole 6. One end of the hollow hole 5 is connected to the through hole 6, and the other end is connected to either the top wall or the bottom wall of the base 1.

[0030] To make the trailer more convenient to use, such as Figure 1 and Figure 2 As shown, this utility model designs the outer end wall of the end cap 4 to have a smooth transition from back to front, making the outer end of the end cap 4 arc-shaped. When encountering an obstruction, it can smoothly move away under the action of the arc, thereby reducing sharp collisions between the two, protecting against external objects and extending the service life of the tractor. A first connector 8 is also hinged to the top wall of the base 1. The first connector 8 can rotate along the axial direction of the support rod 2. Specifically, two oppositely arranged pin sleeves 7 are provided on the top wall of the base 1, and a pin shaft 13 is provided at the lower end of the first connector 8. The two ends of the pin shaft 13 are inserted into the corresponding pin sleeves 7 on their respective sides, realizing the rotational installation of the first connector 8 on the base 1. A second connector 9 is hinged to the first connector 8. Specifically, a slot 19 is provided on the lower end wall of the second connector 9, and a pin 17 is provided on the upper end of the first connector 8. A first pin hole 18 is provided on the pin 17, and the pin 17 is inserted into the slot 19. A second pin hole 14 is provided on the second connector 9, which can be aligned with the first pin hole 18. In this way, the first connector 8 and the second connector 9 are pinned together by fitting the same pin in the first pin hole 18 and the second pin hole 14, so that the second connector 9 can rotate radially along the support rod 2. A mounting hole 10 for installing a mop handle is provided on the second connector 9, so that the mop handle can be installed in the mounting hole 10, allowing the mop handle to rotate omnidirectionally within the hemisphere above the base 1, making it more convenient to use.

[0031] The aforementioned support rod 2 is made of rust-free tubing such as aluminum, aluminum alloy, stainless steel, or fiberglass. The base 1 and end cap 4 are made of injection molded parts, which prevents the bracket from rusting and avoids corrosion when it is fitted inside a wet cloth cover. This not only avoids contaminating the cleaning cloth but also extends its service life.

[0032] A mop handle can also be installed on the mounting hole 10, and a cleaning cloth can be placed on the mop frame to form a push mop.
