Description
Technical field
The present invention relates to electric car component technology field, is especially a kind of electric car brake pipe.
Background technology
Electric car is primarily referred to as pure electric coach, is travelled all of electric energy, and noise is small when the electric car is run, riding stability
Height, and zero-emission is realized, therefore in the relatively intensive city of population, the electric car is easy to be received and liked by people.Mesh
Before, electric car typically uses air-pressure brake, the air compressor that compressed air used in braking carries from engine.Air pressure
After contracting machine compresses air, by the brake pipe of certain length to air dryer, after drying process, into compressed air brake system
System, air compression when, temperature also can be raised accordingly, and temperature can be reduced gradually when passing through brake pipe, while produce moisture content, need through
Air dryer drying process is crossed, Pneumatic braking system could be entered, ensures that the parts in brakes will not corrosion.Air
Temperature finite value requirement of the drier to intake air, generally no greater than 65 degrees Celsius.Therefore it is to meet air in brake pipe
Temperature drop requirement must just extend the length of brake pipe, still, electric car will improve because structure is limited and brake length of tube and will can only make
Dynamic pipe is carried out coiling in enging cabin and surround.And brake pipe typically uses metal tube at present, metal tube is being coiled after, by
In the reason for its hardness, it is difficult to the brake pipe coiled after carry out to installation is fixed and distribution, due to narrow and small knot inside electric car
The limitation of structure, cause the installation of brake pipe very inconvenient.
The content of the invention
The technical problem to be solved in the present invention is the defects of overcoming above prior art, there is provided one kind can overcome electric car
Internal small space limitation, and the convenient electric car brake pipe installed and be distributed.
The technical solution of the present invention is to provide a kind of electric car brake pipe with following structure：It includes metal material
The braking tube body of matter, one end of the braking tube body are provided with elastic hose, and the elastic hose and braking tube body pass through
Connector is connected, and described connector includes hollow housing, and one end of the housing is fixedly connected with braking tube body, housing
The end face of the other end is provided with the ring-type slot to extend internally, and described ring-type slot inserts for the end of elastic hose；It is described
Housing on the inside of ring-type slot is provided with the ring-type convex wall for stretching out housing end face, and the outer circle wall of the ring-type convex wall is provided with more
The radial protrusion of individual ring-type；The housing is provided with the hold-down mechanism for compressing elastic hose in ring-type slot.
After above structure, electric car brake pipe of the present invention compared with prior art, has advantages below：The electric car is braked
Pipe is by the way of the braking tube body and elastic hose of metal material are combined, due to the flexible of elastic hose, so that
Allow to overcome small space limitation inside electric car when brake pipe installation, distribution, multi-angle bending, and install very convenient；Separately
Outside, braking tube body is connected with elastic hose by connector, and connector first connects one end of the housing of connector in connection
Braking tube body is connect, then inserts elastic hose in ring-type slot, stretches out shell because the housing on the inside of ring-type slot is provided with
The ring-type convex wall in body end face, and the outer circle wall of ring-type convex wall is provided with the radial protrusion of multiple ring-types, housing, which is provided with, to be compressed
The hold-down mechanism of elastic hose in ring-type slot, therefore, it is more steady that the connector makes braking tube body be connected with elastic hose
It is fixed, firm.
Preferably, spiral connects a clamp nut, the excircle of the housing on housing on the outside of the ring-type slot
Wall is provided with multiple breach circumferentially distributed along housing, and described breach is connected with ring-type slot, each breach two in
Side wall is provided with two relative necks of opening；A roller, the rotating shaft gap between two ends of the roller are provided with each breach
Coordinate in two necks, the inner inwall of the clamp nut is provided with interior thick outer thin compression inclined-plane, at clamp nut
When impaction state, the outer wall of the breach internal trolley is fitted with compressing inclined-plane, and ring-type slot is arranged on the inside of roller
It is interior.When connecting elastic hose, one end of elastic hose is set in ring-type convex wall, and makes one end insertion ring of elastic hose
In shape slot, clamp nut, the roller compressed in inclined-plane compression breach of clamp nut are then tightened, and roller is inwardly extruded
Elastic hose in ring-type slot, elastic hose is compressed tightly against in ring-type slot, make the connection of elastic hose more firm,
It is not easy to release.
As an improvement the outer face of the clamp nut is provided with an endless groove, it is arranged with the elastic hose
One spring, one end of the spring are connected in endless groove.The spring plays the company of the housing of protection elastic hose and connector
The place of connecing is not broken.
As an improvement the outer circle wall of the braking tube body is provided with an annular boss, one end of the housing
Face is provided with a stepped hole, and described annular boss is arranged in stepped hole；It is hollow that one is arranged with the braking tube body
Pressing plate, the madial wall of the pressing plate and the madial wall of annular boss offset, and the madial wall of pressing plate is provided with tapped ring
Shape wall, the outer circle wall of the housing are provided with the external screw thread being connected with the internal thread spiral of annular wall.The hollow pressing plate set
It is located on braking tube body, and the external screw thread connection on the annular wall internal thread of pressing plate and the outer circle wall of housing, so that system
The annular boss of dynamic tube body is tightly pressed against in stepped hole, so that the housing of connector is tightly connected to braking tube body
Together.
