[0015] The following description is used to disclose the utility model so that those skilled in the art can realize the utility model. The preferred embodiments in the following description are only as examples, and other obvious variants can be thought of by those skilled in the art.

[0016] As Figs. 1 to 3 The utility model discloses a conversion joint, is connected with the brush handle of swimming pool brush, and the brush head of different functions can be connected with the conversion joint, realizes that one brush handle can match multiple functional brush heads, reduces use cost, improves the compatibility of brush handle. The conversion joint includes the body 100, and is the hollow structure's cylindrical structure, including the first socket 110 connected with the brush handle and the second socket 120 for installing the brush head, the first socket 110 is detachably fixed with the brush handle, and the brush head is detachably fixed with the second socket 120, and different brush heads are replaced according to different cleaning needs, realizes that one brush handle matches different brush heads.

[0017] Specifically, the body 100 includes a connecting section 130 and an adapter section 140 integrally formed with the connecting section 130, an inner wall of the connecting section 130 is formed with threads for fixedly connecting with external threads of a brush handle connecting end, a first opening 131 is formed in a peripheral wall of the connecting section 130, the first opening 131 is a threaded hole, a locking bolt 200 is screwed into the first opening 131 until one end is tightly pressed against an outer wall of the brush handle connecting tube, thereby achieving fixed connection of the first socket 110 with the brush handle connecting end. Preferably, the first opening 131 is two, symmetrically arranged about an axis of the body 100, and the two locking bolts 200 respectively pass through the two first openings 131, so that the locking force is uniformly distributed, and the body 100 is more stably connected with the brush handle.

[0018] The inner diameter of the adapter section 140 is greater than that of the connecting section 130, the connecting end of the brush head is inserted into the adapter section 140, and the two are fixed, thereby completing installation of the brush head. The peripheral wall of the adapter section 140 is formed with a second opening 141 penetrating the peripheral wall, and correspondingly, the outer periphery of the connecting end of the brush head is formed with elastic protrusions symmetrically about the axis thereof, the elastic protrusions are matched with the second opening 141, when the elastic protrusions do not reach the position of the second opening 141, the elastic protrusions are in a compressed state, and after passing through the second opening 141, the elastic protrusions restore to a pop-up state, pop up from the second opening 141, and a "click" locking sound is heard, thereby achieving clamping and fixing of the brush head with the adapter section 140.

[0019] The working principle of the utility model is as follows: the adapter section 140 is fixedly inserted with the connecting end of the brush head, thereby achieving fixing of the two, the fixed insertion mode is compared with the structure of the prior art in which the brush handle and the brush head are uniquely matched, the size precision requirement is lower, the pipe diameter size of the connecting end of the brush head is within a specified size range, and the connecting end can be easily inserted into the adapter section 140, thereby achieving fixing of the two. By additionally arranging the conversion structure, the brush head can be matched with various brush handles, one brush handle can be matched with various brush heads, and the compatibility of the brush handle is improved. The elastic protrusions on both sides are pressed to achieve disengagement of the connecting end of the brush head from the connecting section 130, thereby shortening the time for replacing the brush head and improving the replacement efficiency.

[0020] The basic principle, main features and advantages of the utility model are shown and described above. It should be understood by those skilled in the art that the utility model is not limited by the above-mentioned embodiments, the above-mentioned embodiments and descriptions in the specification are only the principles of the utility model, and the utility model can have various changes and improvements without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed for protection. The protection scope required by the utility model is defined by the appended claims and equivalents thereof.
