Abstract
The utility model relates to a gas cylinder fixing device for natural gas vehicles and is characterized in that: the device comprises a plurality of external supports capable of covering the outer side of a gas cylinder, an intermediate support positioned in the center of the profile of the plurality of external supports, a connecting rod arranged between the intermediate support and the external supports, and a pull tape surrounding outside the profile of the plurality of external supports. The connecting rod is a double-ended threaded bolt penetrating the intermediate support. The external supports respectively comprise an arc-shaped support plate for storing two gas cylinders, a limiting plate positioned at two side of the back of the arc-shaped support plate, and a frame connected with the external supports and the intermediate support via the double-ended threaded bolt penetrating the intermediate support. The contact surface between the gas cylinder fixing device and the gas cylinder is configured to an arc-shaped surface, so as to efficiently reduce the displacement of the gas cylinder during the emergency braking of the vehicle. The double-ended threaded bolt can simplify the connection structure and increase the assembly efficiency. The limiting plate is configured to a transition structure which is narrow in the ends and wide in the middle, thereby guiding and restricting the pull tape and ensuring the appearance more beautiful.
Description
(1) technical field
The utility model relates to natural gas supply device technique field, particularly a kind of natural gas-powered car gas-cylinder retaining assembly.
(2) background technology
Existing medium and heavy, the heavy natural gas vehicle side gas cylinder overwhelming majority is two, makes the car load gas cylinder volume be very limited, and has reduced the continual mileage of automobile.Few and the skewness of natural gas filling station quantity has seriously restricted the marketing of this environmental protection vehicle of natural gas vehicle in addition.At present indivedual vehicles adopt side four gas cylinders, but gas cylinder supporting structure complexity, loosening easily, reliability is low, can't realize using in batches.
(3) summary of the invention
The utility model is in order to overcome the deficiency of above technology, provide a kind of simple in structure, be easy to assemble, natural gas-powered car gas-cylinder retaining assembly that reliability is high.
The utility model is realized by following measure: a kind of natural gas-powered car gas-cylinder retaining assembly, it is characterized in that: comprise several outer supports that can wrap up the gas cylinder outside, be positioned at the intermediate support at the profile center of several outer supports formations, be provided with pipe link between intermediate support and the outer support, the outer ring of the profile that outer support constitutes is wound with drawstring.
Pipe link described in the utility model is the double end stud that runs through intermediate support.
Outside the utility model outer support inboard and the intermediate support be and the cooresponding circular arc in the gas cylinder outside, not only increased area of thrust surface, make gas cylinder and support force even; And increased friction force, can effectively reduce collecting together of gas cylinder at the automobile emergency glancing impact.
Outer support described in the utility model comprises the support arc plate that holds two gas cylinders, is positioned at the positioning plate that supports arc backboard face both sides, has a support to link to each other with intermediate support with outer support by the double end stud that passes intermediate support.
Its profile of the utility model is square, and outer support is for constituting two and vertical two of foursquare level.
Put up L shaped for described in the utility model.
The beneficial effects of the utility model:
1. the contact surface of the utility model and gas cylinder all adopts big cambered surface, and the one, increase area of thrust surface, make gas cylinder and support force even; The 2nd, increase friction force, can effectively reduce collecting together of gas cylinder at the automobile emergency glancing impact.Collect together
2. adopt double end stud to connect and to simplify connection structure, improve efficiency of assembling.
3. the side positioning plate adopts the wide transition structure in narrow centre, two ends, and the one, can reduce material weight satisfying under the situation of performance requriements, the 2nd, the upper end carries out the transition to the upper limit plate naturally, not only drawstring is had and lead and effect of contraction, and profile is more attractive in appearance.
Low, the compact conformation of cost, be convenient to assembling, reliability height, suitable applying.
(4) description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a running condition scheme drawing of the present utility model.
Among the figure 1, support, 2, horizontal support arc plate, 3, vertically support the arc plate, 4, double end stud, 5, strain pin, 6, the drawstring strain pin, 7, socket bolt, 8, the upper limit plate, 9, intermediate support, 10, the side positioning plate, 11, drawstring.
(5) specific embodiment
A kind of natural gas-powered car gas-cylinder retaining assembly shown in Fig. 1 .2, comprise the L bracket 1 that links to each other with the chassis side rail side, can wrap up several outer supports in the gas cylinder outside, be positioned at the intermediate support 9 at the profile center of several outer supports formations, the outer ring of the profile that outer support constitutes is wound with drawstring 11, link to each other by the double end stud that passes intermediate support 9 between intermediate support 9 and the outer support, outer support is inboard and intermediate support 9 outsides are and gas cylinder outside cooresponding circular arc.
Described outer support comprises the horizontal support arc plate 2 that is welded on respectively on support 1 inboard horizontal surface and the vertical plane, vertically supports arc plate 3, is positioned at the upper limit plate 8 that supports arc backboard face both sides, side positioning plate 10; Upper limit plate 8 links to each other with support 1 lower surface by a double end stud that passes midship mounting housing 9, and side positioning plate 10 links to each other with support 1 vertical plane by two double end studs 4.
During installation, weld horizontal supports arc plate 2, vertically supports arc plate 3 respectively on support 1 inboard, upright and horizontal surface.Earlier the good support 1 of welding is fixed in the chassis side rail side, two gas cylinders is positioned on the horizontal support arc plate 2 then; One end is welded with in the hole that the female double end stud of the back of the body 4 inserts on supports 1 vertical plane and fastening, at double end stud 4 other ends support arc plate and the pretension that has lateral confinement position plate 10 is installed again; Place intermediate support 9 at double end stud 4 and gas cylinder midway location, after other two gas cylinders are put well, the support arc plate that has upper limit plate 8 that is fastened with double end stud passed intermediate support 9 and insert hole and pretension on support 1 lower plane; Level and vertical double end stud are replaced pretension until fastening; After walking around side positioning plate 10 and upper limit plate 8 with drawstring 11 at last, by socket bolt 7, drawstring strain pin 6 and the strain pin 5 on snapping in support 1 be connected.
