Abstract
The utility model relates to a bend with an expanding hole which is characterized by comprising an upper pipe body and a lower bend. The upper end of the upper pipe body is provided with the expanding hole. The outer wall at the lower end of the lower bend is provided with an insert hole. According to the scheme, the upper end of the upper pipe body is provided with the expanding hole, and the outer wall at the lower end of the lower bend is provided with the insert hole, so that in a mounting process, a pipe fitting with a convex rib at one end is directly inserted into the expanding hole of the upper pipe body by using the plastic elasticity, and the lower end of the lower bend is inserted into the inner wall of the other pipe fitting by using the insert hole. The bend with the expanding hole is simple in structure, low in manufacturing cost; besides, as the bend can be connected in an inserting manner, the mounting is convenient and fast.
Description
Technical field
The utility model relates to elbow, particularly relates to the enlarging elbow, belongs to the plastic pipe field.
Background technique
The elbow of at present existing plastic pipe mostly is to be connected through screw thread rotation with plastic water pipe, or plastic water pipe is inserted elbow, tightens fixing through nut at the elbow oral area again; The shortcoming that this class formation exists is: connect through screw thread rotation; Install cumbersomely, efficiency of assembling is low, fixes through nut screwing clamping; Complex structure, manufacture cost is high.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming that prior art exists, to provide a kind of simple in structure, quick, convenience being installed, the enlarging elbow of low cost of manufacture.
The technological scheme of the utility model enlarging elbow is: it is characterized in that comprising upper tube body and following elbow, be shaped on enlarging in the upper end of upper tube body, the lower end outer wall of following elbow is shaped on socket.
The utility model discloses a kind of enlarging elbow, be shaped on enlarging through the upper end at upper tube body, the lower end outer wall of following elbow is shaped on socket; During installation, utilize the elastic vertical of plastics to patch in the enlarging of upper tube body a pipe fitting that is shaped on convex tendon, the lower end of following elbow utilizes socket to insert another root pipe fitting inner wall; Structure is very simple; Low cost of manufacture through socket connection, is installed quick, convenient.
The utility model enlarging elbow, the tilt angle alpha between described upper tube body and the following elbow is 165 °.Be applicable to that the corner is the connection of two plastic water pipes of 165 °.
Description of drawings
Fig. 1 is the structural representation of the utility model enlarging elbow.
