For the purposes and advantages of the present utility model to become more apparent, the following detailed description of the utility model will be taken in conjunction with the accompanying examples, with the understanding that the following text is intended to describe only one or several specific embodiments of the utility model and is not intended to limit the scope of the utility model to the exact geometric definition, as used herein, the terms up, down and left to right are not limited to the exact geometric definition thereof, but rather include tolerances for machining or human error, and the specific features of the line connection protecting housing are set forth in detail below:

referring to fig. 1 to 4, a pipeline connection protective housing according to an embodiment of the present utility model includes two middle plates 10 disposed symmetrically up and down, two side plates 12 are disposed on front and rear sides of the two middle plates 10, two extension plates 11 disposed symmetrically front and rear in each middle plate 10, two outer sealing strips 21 disposed symmetrically left and right on inner sides of each middle plate 10 and two inner sides of the side plates 12 disposed symmetrically upper, two inner sealing strips 22 disposed symmetrically left and right on inner sides of each extension plate 11, and each middle plate 10, each extension plate 11, and each side plate 12 are made of plastic having elasticity.

Two first limit grooves 20 which are symmetrical from front to back are arranged in each middle plate 10, and a second limit groove 13 is arranged in each side plate 12.

Each first limiting groove 20 is internally provided with a first limiting block 19 in a sliding fit manner, each second limiting groove 13 is internally provided with a second limiting block 14 in a sliding fit manner, and each extension plate 11 is respectively fixed between the corresponding side of the first limiting block 19 and the corresponding side of the second limiting block 14.

Each of the extension plates 11 is slidably engaged with the middle plate 10 and the side plates 12 of the corresponding side, respectively.

A fixing plate 15 is fixed on the outer side face of each side plate 12, and bolts 18 distributed at equal intervals are arranged in the fixing plates 15 on the front side and the rear side in a penetrating mode.
