Abstract
The utility model discloses a self-locking boiler wind cap. The self-locking boiler wind cap comprises a cap head and a tray, wherein the edge of the tray is provided with positioning holes; the outer side wall of the cap head is provided with L-shaped pin plate grooves corresponding to the positioning holes; the L-shaped pin plate grooves are composed of vertical grooves and horizontal grooves which are communicated; the cap head and the tray are positioned and locked by virtue of L-shaped positioning pins; each L-shaped positioning pin consists of a pin shaft body and a fastening plate; the L-shaped positioning pins are inserted into the positioning holes downwards along the vertical grooves, and are rotated to fasten the fastening plate in the horizontal grooves. The self-locking boiler wind cap disclosed by the utility model has the advantages that the wind cap and the tray are positioned and locked by virtue of the L-shaped positioning pins, so that the phenomenon that the wind cap falls naturally is avoided and the normal operation of a boiler is guaranteed.
Description
Technical field
The utility model relates to a kind of boiler accessory, specifically belongs to self-locking Wind cap for boiler.
Background technology
Chinese patent ZL200920143043.X discloses a kind of Industrial Boiler blast cap, and this kind of blast cap there will not be to fall cap phenomenon, and single cap head occurs only damaging and cap head need to be taken off and again changes one, and cap bar does not need again to change.But at this kind of blast cap in use, between cap head and pallet, easily occur mutually sliding, cause pallet because return phenomenon appears in stove wind effect, thereby cap head is come off naturally.
Utility model content
The purpose of this utility model is to provide a kind of self-locking Wind cap for boiler, and between cap head and pallet, by L shaped alignment pin positioning and locking, the phenomenon that cap head there will not be nature to come off, has guaranteed the normal operation of boiler.
The technical solution of the utility model is as follows:
Self-locking Wind cap for boiler, include cap head, pallet, described tray edge has locating hole, on described cap head lateral wall, have the L shaped pin plate groove corresponding with locating hole, L shaped pin plate groove is to consist of the vertical slot being connected and transverse groove, and between cap head and pallet, by L shaped alignment pin positioning and locking, L shaped alignment pin is comprised of bearing pin body and pinch plate, L shaped alignment pin can insert in described locating hole downwards along vertical slot, rotates L shaped alignment pin its pinch plate is sticked in described transverse groove.
Described tray edge has three equidistantly and is positioned at the locating hole on same circumference, and cap head lateral wall has a L shaped pin plate groove, and alignment pin positioning and locking is passed through in 120 ° of the every rotations of pallet between cap head and pallet.
Described tray edge has two equidistantly and is positioned at the locating hole on same circumference, and cap head lateral wall has a L shaped pin plate groove, and the every Rotate 180 ° of pallet passes through alignment pin positioning and locking between cap head and pallet.
Described pallet madial wall is provided with terminal pad, has the endoporus communicating in terminal pad, pallet, on terminal pad madial wall, has welding groove.
On cap head lateral wall of the present utility model, have the L shaped pin plate groove corresponding with locating hole, during locking positioning, L shaped alignment pin can insert in locating hole downwards along the vertical slot of L shaped pin plate groove, rotating L shaped alignment pin is sticked in its pinch plate in described transverse groove, so, realize between cap head and pallet by L shaped alignment pin positioning and locking, the phenomenon that cap head there will not be nature to come off, has guaranteed the normal operation of boiler.
