The model utility content
At the compact structure that exists in the prior art owing to locomotive itself, cause mounting and dismounting the big problem of stucco flexible pipe difficulty, the purpose of this utility model provides a kind of locomotive sand pipe connector, can carry out the installation and removal of stucco flexible pipe very easily.
To achieve these goals, the utility model adopts following technological scheme:
A kind of locomotive sand pipe connector, be located between the sand sprayer and sand pipe outlet steel pipe of locomotive, comprise the stucco flexible pipe, also comprise link, described link is located at the two ends of stucco flexible pipe, one end and the stucco flexible pipe of link are connected and fixed, and the other end is connected and fixed with sand sprayer and sand pipe outlet steel pipe respectively.
Described link comprises connecting head, fixed cover, locking device, fastening screw, interior cover and overcoat, and an end and the connecting head of fixed cover are connected and fixed, and the other end is connected and fixed with interior cover, overcoat respectively; Interior cover docks with the endoporus of fixed cover, outside overlapping in overcoat is sheathed on; The locking device is located at the outside of fixed cover and is flexibly connected with fixed cover; The stucco flexible pipe is located between interior cover, the overcoat, puts outward and offers screw hole, and fastening screw is by the fixing stucco flexible pipe of screw hole.
Described link also comprises rubber pad, and rubber pad is located between connecting head and the fixed cover.
Described outer the putting that is connected with sand pipe outlet steel pipe has osculum.
Compared with prior art, a kind of locomotive sand pipe connector of the present utility model, be located between the sand sprayer and sand pipe outlet steel pipe of locomotive, comprise the stucco flexible pipe, also comprise link, described link is located at the two ends of stucco flexible pipe, and an end and the stucco flexible pipe of link are connected and fixed, and the other end is connected and fixed with sand sprayer and sand pipe outlet steel pipe respectively.By methods such as link adopt are inserted and extracts, depresses and draw back, can mount and dismount the stucco flexible pipe easily.Characteristics such as the utility model also has easy to operate, sturdy and durable, cheap, and novel structure is functional, and is simple and practical.
Description of drawings
Fig. 1 is the application structure schematic representation of locomotive sand pipe connector in the prior art;
Fig. 2 is the application structure schematic representation of locomotive sand pipe connector of the present utility model;
Fig. 3 is the decomposing schematic representation of locomotive sand pipe connector of the present utility model.
Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
See also Fig. 2, a kind of locomotive sand pipe connector 10 shown in Figure 3, be located between the sand sprayer 2 and sand pipe outlet steel pipe 3 of locomotive, comprise stucco flexible pipe 11, also comprise link 12, described link 12 is located at the two ends of stucco flexible pipe 11, one end and the stucco flexible pipe 11 of link 12 are connected and fixed, and the other end is connected and fixed with sand sprayer 2 and sand pipe outlet steel pipe 3 respectively.Link 12 comprises locking device 123, fastening screw 124, interior cover 125 and the overcoat 126 of connecting head 121, fixed cover 122, convex, and an end and the connecting head 121 of fixed cover 122 are connected and fixed, and the other end is connected and fixed with interior cover 125, overcoat 126 respectively; In cover 125 dock with the endoporus of fixed cover 122, overcoat 126 is sheathed on interior overlapping outside 125; A pair of locking device 123 is symmetrically set in the outside of fixed cover 122 and flexibly connects with fixed cover 122; Cover 125 in stucco flexible pipe 11 is located at, between the overcoat 126, offer screw hole on the overcoat 126, fastening screw 124 is by the fixing stucco flexible pipe 11 of screw hole.Link 12 also comprises rubber pad 127, and rubber pad 127 is located between connecting head 121 and the fixed cover 122.And have the osculum (not shown) on the overcoat 126 that sand pipe outlet steel pipe 3 is connected.10 fens total upper and lower two covers of sand pipe connector, top is sealed type, avoiding rainwater to enter sandpipe causes silica sand moist and lose flowability, its integral body is made of stainless steel, avoid being subjected to the site environment influence of open-air, high temperature, dust, thus the total quality and the working life of improving the sandpipe connector; Be perforate below, rainwater enters in the sandpipe connector overcoat, flows out from the hole automatically, prevents that rainwater from entering in the sandpipe, has put fastening screw 124 outward and has been used for fixing stucco flexible pipe 11.
