Abstract
The invention discloses a gas cylinder fixing device with automatic compensation of a tightening force. The gas cylinder fixing device with the automatic compensation of the tightening force comprises a gas cylinder tying band and a gas cylinder bracket, wherein the gas cylinder typing band is connected with the gas cylinder bracket through a bolt. A tightening force automatic compensation device is arranged on the bolt and comprises a sleeve and a spring. The sleeve is sleeved on the bolt, the bottom end of the sleeve is contacted with the gas cylinder bracket in an abut mode when the tightening force automatic compensation device is in a tightened state, and the spring is sleeved on the sleeve and fixed between the head portion of the bolt and the gas cylinder tying band. According to the gas cylinder fixing device with the automatic compensation of the tightening force, through the additional arrangement of the sleeve and the spring on the bolt, and the tensile force of the spring, the distance between the gas cylinder tying band and the gas cylinder bracket remains unchanged, and therefore the fixing for a gas cylinder is strengthened, the gas cylinder looseness caused by factors of rubber aging an the like is effectively avoided, and the safe reliability when a fuel automobile is used is guaranteed.
Description
Technical field
The present invention relates to a kind of gas-cylinder retaining assembly, particularly a kind of gas-cylinder retaining assembly with the tightening force auto-compensation.
Background technology
The on-board hydrogen bottle of fuel-cell car generally is arranged under the reserve cabin of car, adopts steel bandage and the structure level of rubber gasket to fix onboard.This fixed form because rubber shock-absorbing function actv. has been avoided the vibrations to the hydrogen bottle, be widely used Expo with fuel-cell car on.Chinese invention patent CN101992685A discloses a kind of gas cylinder mounting bracket of car.But in real-world operation, because exist the operation vibrations of fuel-cell car to add the aging of rubber, the hydrogen bottle easily occurs loosening, has brought so very large potential safety hazard.At present, the mode that can only take to regularly replace rubber pad is carried out the elimination of hidden danger, lacks a kind of device that can effectively avoid the hydrogen bottle to become flexible.
Summary of the invention
Problem to be solved by this invention is to provide a kind of gas-cylinder retaining assembly with the tightening force auto-compensation, overcomes the above-mentioned technical matters that exists in prior art.
A kind of gas-cylinder retaining assembly with the tightening force auto-compensation of the present invention, comprise gas cylinder bandage and gas cylinder carriage, gas cylinder bandage and gas cylinder carriage are bolted, described bolt is provided with the tightening force automatic compensating device, the tightening force automatic compensating device comprises sleeve and spring, jacket casing is located on described bolt, the bottom of sleeve is tightened up under state inconsistent with described gas cylinder carriage at the tightening force automatic compensating device, described spring housing be located on sleeve and be fixed in described bolt head and described gas cylinder bandage between.
The top of sleeve of the present invention is provided with one and encloses the outer, and described spring top is located at below, described outer.
The bend at end of gas cylinder bandage of the present invention forms a horizontal via hole, and be provided with in the knee with described horizontal via hole hole to vertical opening, laterally placing a cross bar in via hole, middle part at cross bar is provided with bolt hole, bolt hole passes with the described bolt of the corresponding confession of described opening and sleeve, and described spring is fixed in above cross bar.
The top of bolt hole of the present invention is provided with the pad with via hole, and described spring supports and is located at above described pad.
Pad of the present invention is elastomeric pad.
Cross bar of the present invention is cylindrical.
By above technical scheme, gas-cylinder retaining assembly of the present invention, by add sleeve and spring on bolt, tension force by spring keeps the spacing of gas cylinder bandage and gas cylinder tray chamber constant, and then reinforcement fixing gas cylinder, the gas cylinder of effectively having avoided causing because of factors such as ageing of rubbers becomes flexible, and has guaranteed fuel automobile safe reliability in use.

The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of gas-cylinder retaining assembly with the tightening force auto-compensation of the present invention, comprise gas cylinder bandage 1 and gas cylinder carriage 6, gas cylinder bandage 1 is connected by bolt 2 with gas cylinder carriage 6, bolt is provided with the tightening force automatic compensating device, the tightening force automatic compensating device comprises sleeve 4 and spring 3, sleeve 4 is set on bolt 2, the bottom of sleeve 4 is tightened up under state inconsistent with gas cylinder carriage 6 at the tightening force automatic compensating device, spring 3 is set on sleeve 4 and is fixed between bolt head and gas cylinder bandage.The present invention is by adding the tightening force automatic compensating device on bolt, when rubber pad is aging when causing gas cylinder to become flexible, the spacing of utilizing the tension force of spring to reinforce gas cylinder bandage and gas cylinder tray chamber is guaranteed the firm of gas cylinder.
For ease of fixing spring and convenient the installation, be provided with one on the top of sleeve 4 and enclose the outer, spring top is located at below, outer (seeing Fig. 3 and Fig. 5).
The fixed sturcture of gas cylinder bandage of the present invention and gas cylinder carriage can for: as Fig. 4, Fig. 5 and shown in Figure 6, the bend at end of gas cylinder bandage 1 is formed a horizontal via hole, and be provided with in the knee with horizontal via hole hole to vertical opening, laterally placing a cross bar 11 in via hole, middle part at cross bar 11 is provided with bolt hole, bolt hole is corresponding with opening to be passed for bolt 2 and sleeve 4, and spring 3 is fixed in cross bar 11 tops.Can disperse bolt to the direct effect power of gas cylinder bandage by cross bar, therefore reduce stress and concentrated, make gas cylinder bandage can bear larger tension force, strengthen the fixing steadiness of gas cylinder.
Gas-cylinder retaining assembly of the present invention when mounted, at first gas cylinder is placed on gas cylinder carriage 6, be equipped with rubber sheet gasket on gas cylinder carriage 6 and gas cylinder bandage 1, prevent the wearing and tearing to gas cylinder self, also play better fixing gas cylinder, then cross bar 11 is put into the horizontal via hole of gas cylinder bandage end, will be inserted in the bolt hole of cross bars 11 with the bolt 2 of sleeve 4, spring 3, and it is fastening with nut 5 that bolt 2 is passed after bolt hole on gas cylinder carriage 6.When initial the installation, with bolt tightening to sleeve bottom and gas cylinder carriage conflict motionless till, spring is in the state of tightening up at this moment; Through an end after the time rubber sheet gasket aging, gas cylinder bandage and gas cylinder tray chamber can produce loosening, spring in the tightening force automatic compensating device produces tension force at this moment, the elastic force of spring acts on gas cylinder bandage by pad and cross bar, make gas cylinder bandage and gas cylinder carriage continue to keep original constant spacing, gas cylinder is stablized motionless.The gas cylinder that the factor such as ageing of rubber of can effectively avoiding gas-cylinder retaining assembly of the present invention causes is loosening, guarantees that ride safety of automobile is reliable.
