Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to an anti-dropping interface structure for connecting ductile iron pipes. Background Art

[0002] Ductile iron pipe refers to the pipe made by high-speed centrifugal casting of molten iron with a size of 18 or above after adding spheroidizing agent, and is referred to as ductile iron pipe, ductile iron pipe and ductile iron pipe, etc. It is mainly used for the transportation of tap water and is an ideal material for tap water pipes.

[0003] Among them, the patent application with application number "CN201620806698.0" discloses "a fire hose quick connector and its anti-detachment interface", which is also an increasingly mature technology. The utility model discloses a fire hose quick connector and its anti-detachment interface. The anti-detachment interface of the quick connector includes a coupling ring installed on the female connector and a pushing ring installed on the male connector; a limit pin structure is provided between the coupling ring and the pushing ring to prevent the pushing ring from approaching the coupling ring, and a slot structure is also provided between the coupling ring and the pushing ring for mating with the limit pin structure to separate the female connector and the male connector. Therefore, during firefighting, due to the presence of the limit pin structure between the coupling ring and the pushing ring, even if the pushing ring encounters a bump, the pushing ring cannot enter the coupling ring to separate the female connector and the male connector. When the quick connector needs to be disassembled, the pushing ring is rotated so that the limit pin structure and the slot structure are mated and matched, thereby pushing the pushing ring into the coupling ring, and conventional disassembly can be achieved;

[0004] The traditional ductile iron pipe connection solution has poor support effect for the body in the later stage, and the impact and pulling effect of conventional ductile iron pipes is not good. It is also difficult to adapt to assembly control and is easy to fall off when lifted, which is not conducive to combined assembly. Utility Model Content

[0034] The assembly mechanism 2 includes a support pole 21 bound by a limiting clamp 191, a fitting side plate 22 is installed on the top of the pole body of the support pole 21, and an upper top plate 23 for support is installed on the top of the plate surface of the fitting side plate 22.

[0035] The use of the limiting clamp 191 and the tightening knob 192 further achieves the replacement of the corresponding ductile iron pipe.

[0036] In this embodiment: an access base 24 is installed at the bottom of the supporting upright 21, and access screws 25 are installed at the four corners of the top of the access base 24. The bottom of the access screw 25 is connected to an adjusting base plate 26, and the bottom of the adjusting base plate 26 is installed with a rotating base 27. The top side of the pipe connector 28 is installed, and the top of the pipe connector 28 is installed with an arc sleeve 29. The middle part of the arc sleeve 29 is clamped with the end of the ductile iron pipe.

[0037] The rotating base 27 and the pipe connector 28 are used in correspondence with the structure of the arc sleeve 29 to achieve lateral lifting support.

[0038] In this embodiment: a transformation mechanism 3 is installed on the side of the rotating base 27;

[0039] The transformation mechanism 3 includes a pipe connection bracket 31 installed at the end of the access base 24, a circular opening 32 is opened in the middle of the pipe connection bracket 31, a side wall bracket 33 is installed at the rear end of the hole of the circular opening 32, a pipe connection cross bar 34 is provided in the middle of the side wall bracket 33, and a fitting cross bar 35 is installed laterally in the middle of the top end of the pipe connection cross bar 34.

The fitting side plates 22 at the lower four corners and the side walls of the rod bodies of the support vertical rods 21 are used to achieve the sharing combination. After the combination of the lower access base 24, the access of the access screw 25 is ensured.
