Abstract
The invention relates to a directly-inserted type connector and an integrated device. The directly-inserted type connector comprises an inserting head body, a pressing sleeve, a clamping ring and a locating ring. A ring-shaped cavity is formed in one connecting end of the inserting head body. The locating ring and the pressing sleeve are arranged on the inner side and the outer side in the ring-shaped cavity. The clamping ring is arranged between the locating ring and the pressing sleeve. A claw used for pressing a pipeline is arranged on the inner side, close to the locating ring, of the clamping ring. When the clamping ring gets close to the locating ring, the clamping ring and the locating ring can form an expanding and matching mechanism so that the claw can expand in the radial direction, and then sleeving space and disassembling space can be provided for the pipeline inserted into the ring-shaped cavity. When the clamping ring gets close to the pressing sleeve, the clamping ring and the pressing sleeve can form a pressing and matching mechanism so that the claw can contract upwards in the radial direction and press the outer contour of the pipeline inserted into the ring-shaped cavity, and the functions of fast assembling and fast disassembling can be achieved on the premise of guaranteeing safety.
Description
Technical field
The present invention relates to Vehicle Engineering, particularly relate to a kind of direct insertion joint and integrating device.
Background technology
Gas circuit quick connector in the market has two kinds: a kind of is bamboo joint type connecting leg male and female connector,
Lock use；Another kind is direct insertion joint, and joint is contained on commercial car valve body, braking

Detailed description of the invention
Below by drawings and Examples, technical scheme is done and further retouches in detail
State.
The detailed description of the invention of the present invention is for the ease of to the design of the present invention, the skill that solved
Art problem, the technical characteristic constituting technical scheme and the technique effect brought have further
Bright.It should be noted that " front " and " afterwards " in the present invention corresponds to direct insertion fitting passage
Inwardly or outwardly, the explanation for these embodiments is not intended that the limit to the present invention in direction
Fixed.As long as additionally, the technical characteristic related in the embodiment of present invention described below is each other
Between do not constitute conflict just can be mutually combined.
For current existing direct insertion joint, the phenomenon that clamping was lost efficacy often occurs, exist bigger
Security risk, the present invention devises a kind of direct insertion joint, by the annular in joint body
Clamping sleeve, bail wire and centring ring are installed, it is achieved that in cavity on the premise of ensuring safety
Carry out the function of quick despatch pipeline.
Connect in first schematic embodiment, such as Fig. 1～Fig. 3 and figure the present invention is direct insertion
Shown in 6, direct insertion joint includes: header body 1, clamping sleeve 2, bail wire 3 and location
Circle 4, a connection end of header body 1 is provided with toroidal cavity, centring ring 4 and clamping sleeve 2 points
The inner side and outer side not being arranged in toroidal cavity, bail wire 3 is arranged on centring ring 4 and compresses
Between set 2, bail wire 3 is provided with the card for compressing pipeline 200 near the inner side of centring ring 4
Pawl 31；
Bail wire 3 to centring ring 4 near time, bail wire 3 and centring ring 4 can form expansion
Matching mechanism is so that claw 31 is expanded in radial directions, then for inserting the pipe of toroidal cavity
Road 200 provides socket space and the withdrawal space；
Bail wire 3 to clamping sleeve 2 near time, bail wire 3 and clamping sleeve 2 can form pressure
Tight fit mechanism is so that claw 31 shrinks in radial directions and compresses the pipe inserting toroidal cavity
On the outline on road 200.
In this schematic embodiment, header body 1 as the agent structure of direct insertion joint,
One connects end and is provided with toroidal cavity, by installing clamping sleeve 2, bail wire 3 in toroidal cavity
And centring ring 4, clamping sleeve 2, bail wire 3 and centring ring 4 are preferably made up of metal material

Property.Wherein, as it is shown on figure 3, the second safe bulge loop 22 is preferably provided in clamping sleeve 2 inner circumferential
Outer end, the first safe bulge loop 32 is arranged on the middle part of bail wire 3 periphery, clamping is effectively ensured
Ring 3 will not depart from away from clamping sleeve 2.
In order to ensure sealing property, as shown in Figure 1 and Figure 5, direct insertion joint also includes arranging
In toroidal cavity and be positioned at the double sealing circle 6 of centring ring 4 front end, double sealing circle 6 energy
Enough connection sealing reliabilities ensureing pipeline 200 and direct insertion joint well, further,
Being provided with dottle pin 5 between double sealing circle 6, dottle pin 5 ensure that between double sealing circle 6
Distance, improves integral sealing area.
In the present invention another preferred embodiment of direct insertion joint, clamping sleeve 2 be provided with for
Be detachably fixed the agnail ring 21 being connected with header body 1, the medial roof of clamping sleeve 2 is by fixed
Position circle 4.Agnail ring 21 ensure that clamping sleeve 2 is reliablely and stablely arranged on header body 1
In, it is also possible to readily accessible get off to install bail wire 3 and centring ring 4, the inner side of clamping sleeve 2
Lean centring ring 4 and can ensure that the fixed installation reliability of centring ring 4.
As the further improvement to above-described embodiment, as shown in Figure 4 and Figure 5, direct insertion connect
Head also includes being arranged on the dust cap 7 connected on end of header body 1, and dust cap 7 is provided with point
Yong Yu not insert the axle sleeve 71 in hollow core tubes 11 and cover the lid set 72 of bail wire 3.Dust-proof
The setting of cap 7 pollutes plug it can be avoided that direct insertion joint enters dust under non-working condition
Internal pipeline.
Present invention also offers a kind of integrating device, it includes joint disassembly work as shown in Figure 7
Tool 13 and several various sizes of above-mentioned, as it is shown in fig. 7, joint disassembly instrument 13 is provided with not
With the recess of size, for various sizes of bail wire 3 force is realized direct insertion connecing
The dismounting of head.Owing to the direct insertion joint of the present invention can realize fast-assembling on the premise of ensuring safety
The function of quick-release, integrating device of the present invention also has above-mentioned Advantageous Effects, at this no longer
Repeat, and several various sizes of direct insertion joint can pass through a joint disassembly instrument 13
Can be achieved with bail wire 3 force is realized the dismounting of direct insertion joint, have higher can be real
Shi Xing.
In one specific embodiment of integrating device of the present invention, as shown in Fig. 4～Fig. 6, straight cutting
Formula joint also includes that another connects the threaded steering knuckle 9 of end, and steering knuckle 10 is provided with O
RunddichtringO 8, pad 10 and dust cap 12, vehicle-mounted valve body 100 and steering knuckle 9 screw thread
Connecting, pipeline 200 connects to come real by being connected end with one of the direct insertion joint as fast spigot
Existing vehicle-mounted valve body 100 and the connection of pipeline 200, when disassembly is desired, only need to be torn open by joint
The notch effect unloading instrument 13 inwardly exerts a force can realize in the outer end of bail wire 3.
Above in association with embodiment embodiments of the present invention are described in detail, but this
Bright it is not limited to described embodiment.For a person skilled in the art, do not taking off
In the case of the principle and connotation of the present invention, these embodiments are carried out multiple change,
Amendment, equivalence are replaced and modification still falls within protection scope of the present invention.
