Description
Technical field
It the utility model is related to automobile air spring, and in particular to the air nozzle in a kind of air spring.
Background technology
With the development of automobile industry, more next higher of requirement of the user to auto NVH performance, air spring is a new generation
The new product of air suspension, its comfort level and performance-adjustable have become the first choice of high-end vehicle, but air spring produces
The ease of use of the parts air nozzle of its core and air-tightness have become the key problem of air spring product, pull-off in product
Power, air-tightness, assembling convenience are the important requirements of air nozzle.
Utility model content
The utility model proposes a kind of air spring Fast Installation air nozzle, solves air nozzle air-tightness, dress in the prior art
The problem of having much room for improvement with property.
What the technical solution of the utility model was realized in：A kind of air spring Fast Installation air nozzle, including outside air nozzle
Set and collet, step are provided with the centre bore in air nozzle overcoat, an end of collet is provided with boss, boss and platform
Rank coordinates, and the side wall of the collet other end is provided with the first groove, and air nozzle jacket internal is equipped with sealing ring.
The sealing ring has two-stage.
The outer wall of the air nozzle overcoat is provided with the second groove.
The application realizes fast insert-pull, and opposite sealing is without influence, and the fixation of tracheae is fast.
Brief description of the drawings
Fig. 1 is the utility model use state diagram.
Fig. 2 is I regions enlarged diagram in Fig. 1.
Wherein：1. collet, 2. air nozzle overcoats, 3. sealing rings, 4. steps, 5. boss, 6. first grooves, 7.
Second groove, 8. pistons.
Embodiment
As shown in Figure 1 and 2, a kind of air spring Fast Installation air nozzle, including air nozzle overcoat 2 and collet 1, outside air nozzle
Step 4 is provided with centre bore in set 2, an end of collet 1 is provided with boss 5, and boss 5 coordinates with step 4, elastic clip
The side wall of first 1 other end is provided with the first groove 6, and the inside of air nozzle overcoat 2 is equipped with sealing ring 3.Preferably, the sealing ring 3 has
Two-stage.First groove 6 can increase the intensity and elasticity of collet 1.
Further, the outer wall of the air nozzle overcoat 2 is provided with the second groove 7.Second groove 7 can increase air nozzle overcoat
Elasticity.
The application is pressed by interference, and air nozzle is pressed to nylon piston 8, and extrusion pressure is up to 2000N, air nozzle overcoat
Two-stage sealing ring 3 in 2 carries out hermetic seal, and hermetic seal effect can reach 0.8mpa*24h pressure drop 0.01mpa, the bullet inside air nozzle
Property chuck 1 utilizes taper（Boss 5 and step 4 are all tapered, the clamping boss 5 of step 4）Coordinate, tracheae is fixed, produce
The pretightning force for the more pulling out the more tight, tracheae withdrawal force ＞ 1mpa.
The application operation principle is as follows：1st, product using when first sealing ring is assembled in air nozzle overcoat, 2, air nozzle is total
Into press fitting to nylon internal piston, 3, insertion tracheae.This air nozzle structure realizes quick plug, to sealing without any shadow
Ring.
