The invention discloses a connecting joint for fire fighting. The connecting joint comprises a joint body, a lower connecting straight pipe, an upper connecting straight pipe, first reinforcement protrusions and second reinforcement protrusions. The right end and the lower end of the joint body are connected with the upper connecting straight pipe and the lower connecting straight pipe correspondingly. A first through hole and a second through hole are formed in the joint body. A step through hole and a third through hole are formed in the upper connecting straight pipe and the lower connecting straight pipe correspondingly. The first reinforcement protrusions are arranged on the outer walls of the two sides of the right angle corner of the joint body. The second reinforcement protrusionsare arranged on the outer wall of the lower connecting straight pipe. Through the arrangement of a right angle portion and a third arc portion, the pipe wall of the corner of the inner side of the joint body is thickened, and therefore the strength of the corner of the inner side of the joint body is increased; through the arrangement of the first reinforcement protrusions, the strength of the side walls of the two sides of the connecting position of the first through hole and the second through hole is increased; and through the arrangement of the second reinforcement protrusions, materials are saved, and meanwhile the strength of the lower connecting straight pipe is increased.
Description
【Technical field】 [0001] The invention relates to the technical field of connecting joints, in particular to the technical field of connecting joints for fire protection. 【Background technique】 [0002] With the development of society, fire protection is particularly important. Firefighters often need to use fire-fighting water pipes in the process of fire-fighting. Connecting joints are a part of connecting fire-fighting water pipes. Fittings, compression fittings and self-securing water fittings. [0003] However, the existing fire-fighting joints have the problems of poor strength at joint corners, insufficient pressure, and poor work reliability, which affect the normal progress of fire-fighting work. Therefore, in view of the above problems, a fire-fighting joint is proposed. 【Content of invention】 [0004] The purpose of the present invention is to solve the problems in the prior art, and to propose a connection joint for fire protection, which can thicken the pipe ...
