Summary of the invention
The purpose of this utility model is to propose a kind of boiler uptake hinge syndeton, it is simple in structure, durable, folding freely, be very suitable for 10 tons of above fuel oils or the forward and backward smoke box of gas boiler.
The purpose of this utility model can be achieved through the following technical solutions:
Boiler uptake hinge syndeton, includes smoke box door, casing, upper hinge part, thrust ball bearing and lower hinge part; Upper hinge part has a connecting rod and upper sleeve pipe, and upper sleeve pipe has upper cased perforated, and one end disjunctor of door connecting rod is connected in pipe box, and the other end of door connecting rod is fixedly connected on smoke box door; Lower hinge part includes bearing pin, sleeve and casing connecting rod, sleeve has sleeve perforation, the upper end of bearing pin has external screw thread, the lower end of bearing pin is connected with sleeve is vertical, on bearing pin, near sleeve place, have support ring platform, bearing pin passes successively the upper cased perforated of thrust ball bearing, upper hinge part and in upper end, setscrew nut is installed; One end of casing connecting rod has external screw thread and adjusting nut is installed, the other end of casing connecting rod is fixedly connected with casing through the sleeve perforation of sleeve, the upper sleeve pipe of hinge part and thrust ball bearing are limited on bearing pin between setscrew nut and support ring platform, and upper hinge part can rotate around the bearing pin of lower hinge part.
The utility model is installed on smoke box door on smoke box casing as upper hinge and the lower hinge of smoke box door.Open before smoke box door, first become flexible adjusting nut, casing connecting rod along lower hinge part moves sleeve away from casing, make smoke box door and casing pine from, rotate again smoke box door, the upper sleeve pipe that cuts with scissors part under the effect of thrust ball bearing minimizing pivoting friction rotates around the bearing pin of lower hinge part, and smoke box door is easily opened.Close after smoke box door, screw adjusting nut until smoke box door compresses and is connected with casing, guarantee the sealing of smoke box.
The utlity model has following substantive distinguishing features and progress:
1, the utlity model has simple in structure, durable feature, light, flexible with the smoke box door folding of its installation, be very suitable for 10 tons of above fuel oils or the forward and backward smoke box of gas boiler;
2, the utility model can also be guaranteed the tight closure of smoke box door and smoke box casing, guarantees the sealing of smoke box.
