the utility model provides a concrete conveying pipe elbow, includes the elbow, the installing port has been seted up in the front of elbow, the inner wall of elbow just is located installing port department and has seted up the invagination district, two through-holes have all been seted up to the left and right sides that just is located the installing port on the elbow, invagination district department is provided with welt and lower welt, go up both ends all set up threaded hole about welt and the lower welt, the lower fixed surface who goes up the welt is connected with the boss, the upper surface of welt is seted up flutedly down, go up the welt and all pass through the mounting screw in the elbow with lower welt.

Furthermore, the size of invagination district is greater than the size of installing port, the length of going up welt and lower welt all equals with the length of invagination district.

Furthermore, the through holes are matched with the screws, and the two through holes are symmetrically arranged on the upper side and the lower side of the elbow.

Furthermore, the threaded end of the screw penetrates through the through hole and is in threaded connection with the threaded hole, and the position of the through hole corresponds to that of the threaded hole.

Further, the boss is located the recess, boss and recess looks adaptation.

Furthermore, the lower surface of the upper lining plate is in contact with the upper surface of the lower lining plate, and the front surfaces of the upper lining plate and the lower lining plate are in contact with the inner wall of the invagination area.

(III) advantageous effects

The invention provides a concrete conveying pipe elbow, which has the following beneficial effects:

(1) this concrete conveying pipe elbow runs through the through-hole through the screw and with screw hole threaded connection to go up welt and lower liner plate and install in the elbow, after the elbow uses for a long time, only need take out the screw, will go up welt and lower liner plate change both can, need not to demolish the elbow, thereby can improve work efficiency, increase the life of elbow.

(2) This concrete conveying pipe elbow through setting up welt and lower welt, can be convenient for go up welt and lower welt from the installing port department get into the elbow in, set up the inseparable type that welt and lower welt between can improve by boss and recess, avoid the elbow the condition of leaking the concrete to appear.
