[0002] At present, in order to be able to protect the tube body made of metal, a matching square tube has been produced, and the tube body made of metal can be inserted into the square tube. The existing square tube is generally injection molded from polypropylene material. , the current square tube has a long strip structure with a rectangular cross-section, and then the metal tube body can be directly inserted into the square tube, but sometimes the friction between the metal tube body and the square tube is relatively large, and the insertion is difficult; In addition, if the contact surface between the square tube and the metal tube body is not large, the metal tube will slip in the square tube, resulting in the instability of the socket between the square tube and the metal tube.

The invention discloses a preinstalled clamping type rectangular sleeve. The preinstalled clamping type rectangular sleeve comprises a pipe body, a fine adjustment mechanism and two preinstalled clamping plates. The middle of the upper end of the pipe body is provided with a preinstalled clamping opening, and the two sides of the preinstalled clamping opening are provided with preinstalled clamping slots. The two preinstalled clamping plates are connected with each other in a butt joint manner, the opposite inner sides of the two preinstalled clamping plates are provided with a fine adjustmentcavity, and the opposite outer sides of the two preinstalled clamping plates are provided with preinstalled clamping strips. The two preinstalled clamping plates are inserted into and clamped in thepreinstalled clamping slots through the preinstalled clamping strips. The fine adjustment mechanism can be installed in the two preinstalled clamping plates in advance, then the two preinstalled clamping plates in which the fine adjustment mechanism is installed are inserted into and clamped in the preinstalled clamping slots of the pipe body, the pipe body does not need to be divided and formed before being installed, most importantly, only the two preinstalled clamping plates need to be detached when the fine adjustment mechanism is maintained, installation and maintenance are quite convenient, and work efficiency is improved.
Description
technical field [0001] The invention relates to a pre-assembled clamping type rectangular casing. Background technique [0002] At present, in order to be able to protect the tube body made of metal, a matching square tube has been produced, and the tube body made of metal can be inserted into the square tube. The existing square tube is generally injection molded from polypropylene material. , the current square tube has a long strip structure with a rectangular cross-section, and then the metal tube body can be directly inserted into the square tube, but sometimes the friction between the metal tube body and the square tube is relatively large, and the insertion is difficult; In addition, if the contact surface between the square pipe and the metal pipe body is not large, the metal pipe will slip in the square pipe again, resulting in unstable socket connection between the square pipe and the metal pipe.
