Problems solved by technology
[0002] The existing connection between the nozzle body and the liquid supply pipe fitting is generally connected by thread, and the connection form is simple and reliable, but there are the following defects: because the liquid in the pipe fitting needs a certain pressure, so in order to connect reliably, it needs to be connected very At the same time, in some technical fields, especially in the case of sandblasting, there is a solid medium in the conveying medium, so an inevitable part of it will enter the threaded joint between the pipe fitting and the nozzle body, which will cause a sharp increase in the connection force between the two , it is more laborious to disassemble, even if the two can be disassembled, it is easy to cause damage to the joint between the two, making it unusable, resulting in great waste

Embodiment Construction
[0010] The present invention includes a nozzle body 1 and a spray head 2 arranged at the front end of the nozzle body 1, a flange 2 is arranged at the rear end of the nozzle body 1, and a baffle 3 extending from the nozzle body 1 is provided at the rear end of the nozzle body 1;
[0011] The front end of the pipe fitting 4 connected to the nozzle body 1 is provided with a flange 2 5 corresponding to the flange 1 2 , and the baffle 3 extends into the interior of the pipe fitting 4 and is in close contact with the inner wall of the pipe fitting 4 .
[0012] The blocking piece 3 is an elastic blocking piece 3 , and an elastic pad 6 is arranged at the front end of the elastic blocking piece 3 .
[0013] The blocking plate 3 and the elastic pad 6 of the present invention are detachably connected, so that when one of the components is damaged, it can be replaced, thus avoiding the waste of undamaged components.

The invention relates to a nozzle connecting structure. The nozzle connecting structure comprises a nozzle body and a nozzle head arranged at the front end of the nozzle body. The back end of the nozzle body is provided with a first flange and a blocking piece extending out from the nozzle body. A second flange corresponding to the first flange is arranged at the front end of a pipe part connected with the nozzle body. The blocking piece extends into the pipe part and makes contact with the inner wall of the pipe part tightly. The nozzle connecting structure is connected through the flanges, the connecting structure of the flanges is simple and connecting is reliable; due to the fact that a connecting bolt of the nozzle connecting structure is located outside the nozzle body and the pipe part, the nozzle body and the pipe part cannot be impacted by conveying mediums inside the nozzle body and the pipe part, accordingly, disassembling is easy, and damage is avoided; meanwhile, the nozzle connecting structure is provided with the blocking piece, due to existing of the blocking piece, the conveying mediums are prevented from flowing out from a clearance which is produced by machining or matching of the flanges, and the nozzle working effect is improved; and meanwhile, the impact force of the conveying mediums on the joint of the nozzle body and the pipe part is also reduced due to existing of the blocking piece, and accordingly the reliability of the nozzle connecting structure is improved.
