Description

Technical Field

[0001] The invention belongs to the technical field of cleaning equipment and relates to a handle, in particular to a universal handle with a sheath for a swimming pool cleaning brush. Background Art

[0002] A swimming pool cleaning brush is a cleaning brush specially used to clean the bottom or wall of a swimming pool.

[0003] A traditional cleaning brush usually includes a brush head, a brush handle and a brush rod. The bottom of the brush head is covered with bristles, the brush rod is for the user to hold, and the brush handle is used to install the brush head and the brush rod. For example, the invention patent with application number 201620682824.6 discloses a swimming pool cleaning brush, including a brush head, a swivel joint, a swivel sleeve and a brush rod. The brush head is arranged horizontally, the swivel joint is inserted in the brush head and is movably connected to the brush head in the vertical direction, the swivel joint can rotate relative to the brush head in a horizontal plane, the swivel sleeve is located in the swivel joint and contacts the brush head, the swivel sleeve can rotate synchronously with the swivel joint, the brush rod is connected to the swivel joint and can rotate relative to the brush head in a vertical plane, and the brush rod is used to be connected to the brush handle. In this structure, the connecting piece in the brush rod can make the aluminum tube-shaped brush handle sleeved and fixed to the brush rod. The brush head is large and heavy, while the connection between the mounting portion at the front end of the brush rod and the brush rod is relatively weak and has low strength. When the brush head is subjected to excessive force, the connection is easily damaged and broken, resulting in a short service life of the cleaning brush; 2. The installation of the brush handle requires the staff to hold the brush rod in one hand and the brush handle in the other hand. When the brush handle is put on the brush rod, the sharp end of the brush handle is easy to cut the hand holding the brush rod, and its safety factor is low and inconvenient to use; 3. The walls of some swimming pools are made of softer materials, while the brush rod in this structure is made of metal material, and its front end has a U-shaped structure for installing the brush head. During use, the U-shaped structure will touch the wall of the swimming pool, causing the pool wall to be scratched, resulting in damage to the wall of the swimming pool, shortening its service life.

[0004] In summary, in order to solve the technical problems existing in the above-mentioned cleaning brush, it is necessary to design a universal handle with a sheath that has high strength, long service life, and is safe and convenient to use. Summary of the invention

[0031] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0032] like Figures 1 to 3As shown, the present invention provides a universal handle with a sheath 20 , which is used for a swimming pool cleaning brush. The handle includes a handle body 10 , a sheath 20 and a connecting piece 30 .

[0033] The handle body 10 is an axially arranged tubular structure, and a U-shaped mounting frame 11 is fixedly connected to the front end of the handle body 10. The mounting frame 11 is used to install the brush head of the cleaning brush. The rear end of the handle body 10 is used to be connected to the handle rod (because the claims of this application do not require protection of the handle rod, it is not shown in the figure). The sheath 20 is sleeved on the handle body 10 and covered outside the mounting frame 11. The sheath 20 is separated from the handle body 10 and can accommodate the handle rod. The connecting piece 30 is movably arranged in the handle body 10 so that the handle rod, the sheath 20 and the handle body 10 can be detachably connected.

[0034] When installing the present structure, the sheath 20 is first inserted from the rear end of the handle body 10 and moved toward the front end of the handle body 10 until it rests against the mounting frame 11. At this time, the sheath 20 is sleeved on the handle body 10 and covered outside the mounting frame 11. When installing the handle rod, the sheath 20 is held by hand, and then the handle rod is inserted from the rear end of the handle body 10 onto the handle body 10. The handle rod can be inserted into the area separated by the handle body 10 and the sheath 20, so that the handle rod is tightly connected to the sheath 20 and the handle body 10, and the stability among the three is better.

[0035] During installation, since the hand holds the sheath 20, the sharp end of the handle is not easy to contact the hand when the handle moves on the handle body 10, thereby improving the safety during installation. At the same time, under the protection of the sheath 20, the strength of the connection between the handle body 10 and the mounting frame 11 is higher, making the handle body 10 not easy to break or be damaged, and its service life is longer.

[0036] Based on the above structure, the present invention has made further improvements and refinements thereto.

[0037] like Figures 1 to 3 As shown, the sheath 20 includes a sleeve portion 21 and a cover portion 22. The sleeve portion 21 is sleeved on the handle body 10 and is detachably connected to the handle body 10. The sleeve portion 21 is separated from the handle body 10 to form a slot 21a that can accommodate the handle rod. The cover portion 22 is an inner hollow structure with a square cross-section. The cover portion 22 has an opening (not shown in the figure). The cover portion 22 is fixedly connected to one end of the sleeve portion 21 and communicates with the sleeve portion 21. The cover portion 22 is covered outside the mounting frame 11, and both ends of the mounting frame 11 extend out of the opening. The cover portion 22 and the sleeve portion 21 are formed integrally.

[0038] The handle body 10 is a tubular structure, and the mounting frame 11 is a U-shaped structure. The two are two different structures. Therefore, the structure of the sheath 20 adopts a combination of a sleeve portion 21 and a cover portion 22. The sleeve portion 21 is sleeved on the handle body 10 to cover the handle rod after installation. The cover portion 22 covers the mounting frame 11 to protect the pool wall and is convenient for users to hold. In this way, the handle body 10 and the mounting frame 11 can be covered to protect the handle body 10, the mounting frame 11 and the connection between the handle body 10 and the mounting frame 11.

[0039] like Figure 2 As shown, the slot 21a is formed by a recessed inner surface of the sleeve portion 21, and a boss 21b opposite to the slot 21a is provided in the sleeve portion 21. When the handle rod is inserted into the slot 21a and abuts against the boss 21b, the handle rod is connected to the handle body 10 through the connecting piece 30.

[0040] While the inner surface of the sleeve portion 21 is recessed to form a slot 21a, a boss 21b is also formed at the same time. The boss 21b has a positioning function. After the handle rod is inserted, as long as the handle rod rests on the boss 21b, the connecting piece 30 can securely connect the handle rod and the handle body 10, thereby achieving rapid installation of the handle rod and the handle body 10, improving installation efficiency and making installation more convenient and flexible.

[0041] like Figures 1 to 3 As shown, the two ends of the mounting frame 11 have two mounting portions 11a that are separated from each other. The two mounting portions 11a are used to mount the brush head of the cleaning brush. The middle part of the mounting frame 11 is located in the cover portion 22. Side cover portions extending toward the mounting portion 11a are respectively formed at both ends of the cover portion 22. The side cover portions are formed by grooves opened on both sides of the cover portion 22. The grooves are provided to adapt to the U-shaped mounting frame 11 to facilitate the installation of the brush head. The side cover portions cover the outer surface and outer side wall of the mounting portion 11a.

[0042] The side cover covers multiple surfaces of the two mounting parts 11a, and while ensuring that the mounting frame 11 can normally install the brush head, the coverage area of ​​the mounting frame 11 is expanded as much as possible, further avoiding the sharp edges of the mounting frame 11 from contacting the user's hands or the swimming pool wall, thereby providing better protection for the user's hands and the swimming pool wall.

[0043] like Figure 2 , Figure 3 As shown, positioning blocks 22 b are protruded on both sides of the inner surface of the cover portion 22 . When the mounting frame 11 abuts against the positioning blocks 22 b , the sleeve portion 21 is connected to the handle body 10 through the connecting piece 30 .

[0044] The positioning block 22b plays a positioning role. When the sheath 20 is inserted into the handle body 10 as a whole, as long as the sheath 20 moves to the mounting frame 11 and rests on the positioning block 22b, the connecting member 30 can securely connect the sleeve portion 21 to the handle body 10, thereby improving the installation efficiency and making the installation more convenient and flexible.

[0045] Furthermore, two first limiting holes 12 are correspondingly provided on the handle body 10, and a mounting hole 21c is correspondingly provided on the sleeve portion 21. The connecting member 30 includes two connecting plates 31 that are connected and can move relative to each other, and first limiting columns 32 are respectively protruded on the outer surfaces of the two connecting plates 31. The first limiting columns 32 extend into the first limiting holes 12 and the mounting holes 21c and connect the sleeve portion 21 with the handle body 10.

[0046] By setting two relatively movable connecting plates 31, the two first limiting columns 32 can move synchronously with the connecting plates 31, and the two first limiting columns 32 can be moved into or out of the first limiting holes 12 and the mounting holes 21c, thereby realizing the quick disassembly and assembly of the sheath 20 and the handle body 10. This structure is simple, easy to use and efficient. In addition, when this structure is used in conjunction with the positioning block 22b structure, when the mounting frame 11 just rests on the positioning block 22b, the first limiting hole 12 coincides with the mounting hole 21c, and the first limiting column 32 can enter into the first limiting hole 12 and the mounting hole 21c. This matching structure improves the installation efficiency and installation accuracy of the sheath 20 and the handle body 10.

[0047] like Figure 2 As shown, the mounting hole 21c is a tapered hole whose diameter gradually decreases from the outer surface of the sleeve portion 21 to the inner portion thereof.

[0048] By providing the tapered hole, the hole wall of the tapered hole is separated from the first limiting column 32, so that it is convenient for the user to press the first limiting column 32 with his fingers, so as to facilitate the disassembly and assembly between the handle body 10, the sheath 20 and the handle rod.

[0049] like Figure 2 , Figure 3 As shown, a second limiting column 33 is also protruding from the outer surface of the connecting plate 31, and a second limiting hole 13 is correspondingly provided on the handle body 10. When the handle rod is sleeved onto the handle body 10 and inserted into the slot 21a, the second limiting column 33 can pass through the second limiting hole 13 and the handle rod to connect the handle rod to the handle body 10.

[0050] The second limiting column 33 and the first limiting column 32 are both installed on the connecting plate 31, and the second limiting column 33 can move synchronously with the first limiting column 32. When the first limiting column 32 is pressed or released, the two second limiting columns 33 can move into or out of the second limiting hole 13, thereby realizing the disassembly and assembly of the handle rod and the handle body 10. The fixation is simple, convenient and efficient. In addition, when this structure cooperates with the boss 21b structure, when the handle rod extends into the slot 21a and rests on the boss 21b, the second limiting hole 13 coincides with the hole on the handle rod, and the second limiting column 33 can move into the second limiting hole 13 and the hole on the handle rod. This matching structure improves the installation efficiency and installation accuracy of the handle rod and the handle body 10.

[0051] like Figure 2 , Figure 3 As shown, the connecting member 30 also includes a limit plate 34, which is an arc-shaped structure and is arranged horizontally. The two connecting plates 31 are respectively connected to the limit plates 34. The limit plates 34 are arranged horizontally and the width of the limit plates 34 is slightly smaller than the inner diameter of the handle body 10.

[0052] Here, the limit plate 34 serves to fix the two connecting plates 31. In addition, the limit plate 34 is laterally located in the handle body 10, and its two ends can respectively rest against the inner surface of the handle body 10, thereby stabilizing the entire connecting piece 30 to prevent the entire connecting piece 30 from shaking and facilitate the disassembly and assembly of the connecting piece 30.

[0053] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
