[0037] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0038] In the following description of the embodiments, the first end is an end close to the cleaning body, and the second end is an end away from the cleaning body.

[0039] like Figure 1-5 As shown, the following embodiments disclose a quick installation structure of a handle of a swimming pool cleaning tool.

[0040] The cleaning device comprises a cleaning body and a handle rod; the cleaning body comprises at least a mounting frame 100, the mounting frame 100 is provided with a tubular connector 110, the connector 110 is movably provided with a locking component 200, the locking component 200 can rotate on the connector 110 under the action of an external force and move axially along the connector 110; the locking component 200 is used to lock and connect the end of the handle rod to the cleaning body;

[0041] The connector 110 is provided with a locking portion and a clamping portion, and the locking component 200 is connected in cooperation with the locking portion, and simultaneously puts the locking portion in a clamping state.

[0042] The above is the basic solution of this embodiment.

[0043] When the handle rod is not installed, the locking component 200 is connected to the connecting head 110, which is a pipe fitting and is hollow inside. When the handle rod is installed, the end portion is inserted into the connecting head 110, and then the locking component 200 is operated to rotate on the connecting head 110 and automatically move toward the side of the cleaning body. During the movement, force is applied to the clamping part on the connecting head 110, so that the clamping part clamps the handle rod inserted into the connecting head 110, thereby locking the handle rod.

[0044] In the prior art, in order to enable the cleaning body to rotate at multiple angles, a hinge structure is usually provided between the connecting head 110 and the mounting frame 100 to enable the connecting head 110 to rotate relative to the mounting frame 100; the specific implementation thereof will not be described in detail herein.

[0045] In this embodiment, the cleaning body is preferably a cleaning brush or a cleaning scoop net.

[0046] Figure 1 The cleaning body is a cleaning brush, and the mounting frame 100 of the cleaning brush and the connecting head 110 are arranged to be hinged, so that the cleaning brush can swing relative to the connecting head 110;

[0047] Figure 2 The cleaning body is a cleaning scoop net (the mesh is not shown), and the mounting frame 100 and the connecting head 110 of the cleaning scoop net are integrally formed.

[0048] In this embodiment, the specific implementation of the locking component 200 is as follows:

[0049] 200 is a nut tube, and an internal thread 210 is provided on the inner wall of the nut tube; the connector 110 is provided with an external thread 111 which is screwed to the locking component 200.

[0050] Reference Figure 4 As shown, the internal thread 210 extends from the first end of the locking component 200 toward the interior of the locking component 200 .

[0051] The clamping part is a plurality of clamping claws 112 connected to the end of the connector 110 and arranged in a circumference, and the inner end surfaces of the plurality of clamping claws 112 form a clamping space 101;

[0052] A clamping gap a is provided between adjacent clamping claws 112;

[0053] Under the action of external force, the multiple claws 112 move toward the center at the same time, reducing the inner diameter of the clamping space 101.

[0054] Specific reference Figure 3 As shown, the claws 112 are formed at the second end of the connector 110, and the clamping gap a extends to the end of the second end, so that the plurality of claws 112 are formed with only the first end having a connection portion; under this structure, a pressure toward the center is applied to the middle or the outer periphery of the second end of the claws 112, and the second end of the claws 112 can be brought closer to the center, thereby reducing the circumferential range formed by the plurality of claws 112, that is, the clamping space 101 is reduced;

[0055] The existence of the clamping gap a ensures that the adjacent clamping claws 112 will not interfere with each other when bending and closing toward the middle, thus leaving room for the clamping claws 112 to move.

[0056] When the internal thread 210 on the locking component 200 is screwed with the external thread 111 of the locking part, the second end of the locking component 200 is set to be tapered, or the diameter of the opening of the second end is smaller than the outer diameter of the clamping part. During the tightening process, the tapered part applies pressure to the outer end surface of the clamping claw 112, squeezing the clamping claw 112 toward the center, thereby reducing the clamping space 101 of the clamping claw 112 and clamping the handle rod.

[0057] In order to better push the holding part, in this embodiment, the opening on the locking component 200 away from the cleaning body is the locking end, and the inner wall of the locking end is provided with a locking surface 220 capable of pushing the holding part.

[0058] Preferably, the locking surface 220 is an annular inclined surface and is tapered outwardly in the axial direction of the locking component 200 .

[0059] Specific reference Figure 4 As shown, the inner diameter of the first end of the locking surface 220 is larger, and the inner diameter of the second end is smaller. Therefore, during the locking process, the first end first contacts the clamping part. As the locking component 200 gradually moves toward one end of the cleaning body, the second end also contacts the clamping part. Since the inner diameter of the second end is small, the locking surface 220 exerts pressure toward the center of the clamping part, pushing the clamping claw 112 toward the center.

[0060] When the locking surface 220 contacts the locking part, it is a line contact, and the friction force is large. When the locking component 200 rotates, scratches will be generated at the contact part, and the claw 112 will be damaged after multiple disassembly and assembly. The specific implementation method for solving this problem in this embodiment is as follows: a guide surface 112.1 is provided on the outer periphery of the outer end of the locking part, and the guide surface 112.1 cooperates with the locking surface 220.

[0061] Specific reference Figure 5 As shown, when the locking component 200 clamps the claw 112, a surface contact is formed between the locking surface 220 and the guide surface 112.1. Therefore, the locking component 200 will not generate scratches on the guide surface 112.1 during the rotation process, thereby maintaining the integrity of the claw 112; and when the locking component 200 moves axially, the locking surface 220 slides along the guide surface 112.1 and generates pressure on the guide surface 112.1. The direction of the pressure is perpendicular to the guide surface 112.1 and toward the center, that is, it is inclined toward the center with the cross section of the connector 110; the component force of the pressure in the inclined direction on the horizontal cross section of the connector 110 pushes the guide surface 112.1 toward the center, thereby bending the second end of the claw 112 toward the center, thereby reducing the clamping space 101.

[0062] In this embodiment, a stop wall 113 is further provided on the connector 110 to stop the position of the locking component 200 .

[0063] Reference Figure 1 As shown, the connector 110 is configured as a thick tube and a narrow tube, the locking portion and the holding portion are located on the narrow tube, and a connecting wall is formed at the connection between the thick tube and the narrow tube, which is a stop wall 113;

[0064] Reference Figure 2 As shown, a stop ring is provided on the connector 110, and the end wall of the stop ring facing the locking part is a stop wall 113;

[0065] When the locking component 200 contacts the stop wall 113 during the tightening process and cannot be tightened further, the connection is in place.

[0066] Based on the above structure, in this embodiment, the inner wall of the locking component 200 is arranged in sequence from the first end to the second end in the axial direction as an internal thread 210 area, an empty tube area and a locking area;

[0067] The connection head 110 is provided with a stop wall 113 , a locking portion and a holding portion arranged in sequence from the first end to the second end along the axial direction.

[0068] Reference Figure 5 As shown, the handle rod is inserted into the connector 110, and the locking component 200 is rotated, and its internal thread 210 is threadedly connected with the locking portion on the connector 110. At the same time, the locking surface 220 on the locking component 200 pushes the guide surface 112.1 on the claw 112, so that the claw 112 bends toward the center to clamp the handle rod.

[0069] In this embodiment, the empty tube area is a portion of the locking component 200 with a smooth inner wall, which is used to connect the internal thread 210 and the locking surface 220 .

[0070] In this embodiment, an anti-slip rib 230 is provided on the outer wall of the locking component 200 .

[0071] The outer periphery of the locking component 200 is a circular surface, which makes it inconvenient to apply force during operation, so an anti-slip rib 230 is provided to increase the friction between the palm and the locking component 200 .

[0072] Preferably, in this embodiment, the anti-slip rib 230 is arranged along the axial direction of the locking component 200 .

[0073] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
