Description
Technical field
The utility model belongs to boiler furnace blast cap technical field, is specially the fixed connection structure between a kind of blast cap and adapter.
Background technology
Generally spot welding type of attachment between current boiler furnace blast cap and adapter.Fig. 1 is cap structure schematic diagram, and Fig. 2 is joint pipe structure schematic diagram, and Fig. 3 is blast cap and adapter connection diagram, and what it adopted is that spot welding is connected and fixed form.Because blast cap and adapter are all foundry goods, therefore spot welding connects and there is two problems, and one is that the welding characteristic of foundry goods is poor, and welding requirements is high; Two is postweldings, when needs dismounting blast cap checks, just blast cap must can be taken off by disconnected for solder joint grinder buffing, and what generally weld use is all alloy electrode, be difficult to polishing, all adopt sledgehammer to beat jarring blast cap in all reality, shake disconnected solder joint with this, but beaing of external force very easily causes adapter, at knuckle place, fracture damage occurs.
Summary of the invention
In order to solve the problem, the utility model provides the fixed connection structure between a kind of blast cap and adapter, and it is simple and convenient that it installs replacing.
Its technical scheme is such: the fixed connection structure between a kind of blast cap and adapter, it comprises blast cap and adapter, described adapter is provided with annular boss, it is characterized in that, described blast cap lower end has inverted L-shaped notch, described annular boss is provided with the inverted L-shaped buckle coordinated with described inverted L-shaped notch, described inverted L-shaped buckle inlay card realizes the connection of described blast cap and described adapter in described inverted L-shaped notch.
It is further characterized in that, the lower ending opening size of described inverted L-shaped notch is greater than described inverted L-shaped buckle upper surface size, described inverted L-shaped buckle and described inverted L-shaped notch inwall interference fit;
Described blast cap lower end evenly has multiple described inverted L-shaped notch, and described annular boss is provided with the multiple described inverted L-shaped buckle of cooperation, described inverted L-shaped buckle is arranged in the same way clockwise or in the same way counterclockwise.
After adopting structure of the present utility model, when blast cap is installed, detaining after inverted L-shaped notch is aimed at inverted L-shaped buckle makes inverted L-shaped buckle enter inverted L-shaped notch, then rotate blast cap and namely complete connection, when boiler plant runs, blast cap just can be fixed in adapter securely, can not come off, when needing to take off blast cap, also only need to rotate blast cap in the other direction just can easily take off, installation is changed simple and convenient.

Detailed description of the invention
See Fig. 4, Fig. 5, shown in Fig. 6, a fixed connection structure between blast cap and adapter, it comprises blast cap 1 and adapter 2, adapter 2 is provided with annular boss 3, blast cap 1 lower end evenly has two inverted L-shaped notches 4, annular boss 3 is provided with two inverted L-shaped buckles 5 coordinated with inverted L-shaped notch 4, inverted L-shaped buckle 5 is arranged in the same way clockwise or in the same way counterclockwise, and inverted L-shaped buckle 5 inlay card realizes the connection of blast cap 1 and adapter 2 in inverted L-shaped notch 4; The lower ending opening size of inverted L-shaped notch 4 is greater than inverted L-shaped buckle 5 upper surface size, and inverted L-shaped buckle 5 and inverted L-shaped notch 4 inwall interference fit, guarantee that the convenient Simultaneous Stabilization of inlay card is good, can not come off.
