Description

Plastic three-way connecting piece Technical Field The utility model relates to the technical field of household articles, in particular to a plastic three-way connecting piece. Background Mosquito net is a kind of tent that avoids the mosquito to bite, hangs on the support frame in order to enclose the bed in order to isolate the mosquito. The mosquito net becomes a necessity in life of people gradually, and along with the continuous improvement of life quality of people, the requirements of people on the mosquito net are not only satisfied with mosquito prevention, but also attractive appearance, convenient installation and convenient use. In order to improve the convenience of the mosquito net in the use process, a plurality of manufacturers push out the installation-free folding mosquito net, reduce the time consumed in the process of assembling the mosquito net, and avoid the situation of assembling the two components which are matched in error. But in the long-term use process, the connecting rods and the connecting pieces in the mosquito net frame are loosened, so that the problem of falling off is caused. In order to solve the problems in the prior art, a plurality of attempts are made by the skilled in the art, for example, chinese patent application 2023205685743 discloses a folding mosquito net support, and specifically discloses a three-way connecting structure, which is matched with a groove through a protrusion or matched with a connecting rod through an oval and D-shaped profile, so as to fix the connecting rod in a non-rotating sleeving manner, but the limitation on the displacement of the connecting rod in the horizontal direction is weaker, and the limiting effect is poorer. Disclosure of utility model In order to solve the problems, the utility model provides the plastic three-way connecting piece, which is matched with the bulge through the clamp to realize the connection of the connecting cylinder and the connecting rod, so that the limit effect of the connecting cylinder on the connecting rod is enhanced, and the overall structural strength is enhanced. The technical scheme includes that the plastic three-way connecting piece is used for being connected with a mosquito net connecting rod to form a mosquito net frame and comprises a connecting cylinder, wherein the connecting cylinder comprises a transverse connecting cylinder, a longitudinal connecting cylinder and a vertical connecting cylinder, one ends of the transverse connecting cylinder, the longitudinal connecting cylinder and one end of the vertical connecting cylinder are connected at one point in a tandem mode, an included angle is formed between the transverse connecting cylinder and the longitudinal connecting cylinder, a clamp is arranged on the inner wall of the connecting cylinder, a protrusion is arranged on the outer wall of the connecting rod, and the clamp is matched with the protrusion to realize connection between the connecting cylinder and the connecting rod. Further, the number of the clamping bands is two, the clamping bands are arranged on one side far away from the junction in parallel, a groove is formed between the two clamping bands, and when the protrusion is matched with the clamping bands, the protrusion is arranged in the groove. Further, a plurality of long grooves are formed in the connecting cylinder along the circumferential direction, and the long grooves extend downwards to the clamping band from the upper end face of the connecting cylinder. Further, a plurality of wedge blocks are circumferentially arranged on the inner wall of the bottom of the connecting cylinder so as to form a gradually reduced space.
