Description
Technical field
The utility model relates to a kind of Horizontal type vehicle-mounteds to supply gas-cylinder retaining assembly.
Background technique
Gas cylinder is all fixed by the way of bandage fastening in air supply system at present.Bandage include steel band, rubber pad,
Fastening bolt installs rubber pad between gas cylinder and steel band, prevent scratch of steel strip gas cylinder and increase frictional force, by fastening bolt
Screw, so that steel band is tightly embraced gas cylinder, to play fixed effect.
Existing bandage fastening basic structure is that gas cylinder position is determined by saddle, by bandage, fastening bolt, the fixed gas of rubber pad
Bottle, there are three big defects for this mode, are threadedly coupled the most common inherent shortcoming first is that existing --- and it loosens, is especially transported in vehicle
In capable use environment, need regularly to test to fastening bolt.Second is that haveing the defects that bandage fracture.Due to gas cylinder
During inflation/deflation, gas cylinder diameter can change with gas cylinder internal pressure, this directly influences the tired longevity of bandage
Life, long-time service are likely to result in bandage fracture.Third is that installation is inconvenient, since air supply system is generally used for new-energy automobile,
This allows for air supply system and has to accomplish compact layout, and the spacing between bottle and bottle cannot be excessive, and what conventional harness was fixed
Mode between bottle and bottle in narrow space, is not easy to the fastening of bolt, leverages the working efficiency of workpeople.
Utility model content
Because bandage fixed form has the security risk for loosening, being broken, there is also the defects that installation is inconvenient, are to gas supply
System security performance, installation effectiveness cause de-stabilising effect, cause the consequences such as product quality is unqualified, worker's working hour increases.
A kind of more reasonable gas cylinder fixed structure must be designed thus.
After fixed using bottleneck, it is ensured that the fixation of gas cylinder will not generate the phenomenon that loosening, while make gas supply system
The overall space of system is more compact, and gas cylinder installation and system maintenance are more convenient.
A kind of fixation device of Horizontal type vehicle-mounted gas cylinder, including two sets of pedestals and pipe clamp gland, it is a set of for for fixing gas cylinder
The first base of mouth cylindrical part and the first pipe clamp gland, and second base and the second pipe clamp gland for fixing gas bottle tail portion,
And the secure component of lid and bottom seat, such as bolt are clamped for fastener tube.
The pedestal and pipe clamp gland are separable two individual components, and when connection, face shaping is an oblong-shaped
Body；The pedestal and pipe clamp gland are equipped with intercommunicating pore close to end positions, can have bolt to be fastenedly connected two components.It is described
The middle position of pedestal and gland, there are the circular spaces that can accommodate bottleneck size.
For fixing the first pipe clamp gland and first base of gas cylinder valve one end bottleneck, it is equipped with internal screw thread inside it,
Meanwhile the bottleneck of the gas cylinder valve one end installed, it also is provided with the external screw thread being mutually engaged.The first pipe clamp gland and first base
The screw thread pipe clamp of composition ensure that gas cylinder cannot move axially and be unable to radial rotating, caused length during gas cylinder inflation/deflation
Minor change can be dissolved by back-and-forth motion of the bottle mouth of gas cylinder in circular groove pipe clamp spherical shape set.
And it is used to fix the pipe clamp of bottle tail, do not have Design of Screw Thread, is circular groove pipe clamp.
It is as shown in Figure 1 double bottleneck gas cylinder fixing assembling structures, i.e. usage state diagram.As shown in Figure 2 and Figure 3 for for solid
The assembling structure that the first pipe clamp gland and first base for determining bottleneck are constituted, the i.e. assembling structure of screw thread pipe clamp and the second pipe
The assembling structure of lid and second base, the i.e. assembling structure of circular groove pipe clamp are clamped, alleged screw thread pipe clamp below this specification refers both to
The assembling structure of first pipe clamp gland and first base, the assembling structure of alleged circular groove pipe clamp, refers both to the second pipe clamp gland below
And the assembling structure of second base.It is described screw thread pipe clamp is constituted by the first pipe clamp gland and first base to be mounted on fixed bottle valve
The bottle mouth position of door one end, to cooperate the screw thread pipe clamp, the bottleneck of valve gas cylinder also needs threading.The installation of circular groove pipe clamp is fixed
On the bottleneck of gas bottle tail one end, circular groove pipe clamp does not use Design of Screw Thread, does not have external screw thread.
It further includes spherical set that the Horizontal type vehicle-mounted, which supplies gas-cylinder retaining assembly, is used cooperatively with circular groove pipe clamp, when gas cylinder both ends
Bottleneck decentraction when, by the position of the adjustable gas cylinder of rotation of spherical shape set, such as (1) circular groove pipe clamp pedestal and Fig. 3 in Fig. 3
In (2) circular groove pipe clamp gland, be integral part before processing, process after sphere hole to cross and cut, spherical shape set is gently driven in into bottle
The bottleneck of mouth tail end, adjustment spherical shape cover the front-rear position on bottleneck, be put into spherical set can in circular groove pipe clamp pedestal, and make
Spherical shape set can rotate in circular groove pipe clamp, and after circular groove pipe clamp clamps, spherical shape set is not able to rotate.When two bottleneck decentraction of gas cylinder
When, by the position of the adjustable gas cylinder of rotation of spherical shape set, making will not be because of installation concentricity between bottle mouth of gas cylinder and pipe clamp
Error and additional shearing force is generated to bottle mouth of gas cylinder, while ensure that fastening pipe clamp used in bolt service life.
