Detailed Description

Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.

A three-way joint 1 according to an embodiment of the present invention is described below with reference to fig. 1 to 2.

As shown in fig. 1 and fig. 2, the three-way joint 1 according to the embodiment of the present invention includes: a fitting body 10, a tube bundle fitting 20, a valve body fitting 30, and a sensor fitting 40. The pipe bundle connector 20 is arranged on the first side of the connector main body 10, the pipe bundle connector 20 is used for connecting a pipe bundle, the valve body connector 30 is arranged on the second side of the connector main body 10, the valve body connector 30 is used for connecting a valve body or an air cylinder, the sensor connector 40 is arranged on the third side of the connector main body 10, the sensor connector 40 is provided with an opening, and the opening can be used for connecting a sensor.

Wherein the axis of the sensor fitting 40, the axis of the valve body fitting 30, and the axis of the tube bundle fitting 20 are perpendicular to each other, as shown in fig. 1 and 2. That is, two-by-two between sensor joint 40, valve body joint 30 and the tube bank joint 20 are perpendicular, like this, connect the tube bank at tube bank joint 20, after valve body joint 30 pegged graft valve body or gas receiver link, sensor joint 40 direction is confirmed naturally, and sensor joint 40 can not rotate along the axial moreover.

From this, through the axis that sets up sensor joint 40, the axis of valve body joint 30 and the axis of tube bank joint 20 are perpendicular each other, connect the tube bank at tube bank joint 20, valve body joint 30 pegs graft behind valve body or the gas receiver link, the sensor joint 40 direction is confirmed naturally, need not readjustment, accord with the development trend of the quick simple and convenient ization assembly in automobile field, and sensor joint 40 can not follow the axial rotation, can reduce the risk of interfering with border on every side, can avoid the easy discount when the tube bank is assembled simultaneously. In addition, the three-way joint 1 with different directions can ensure that the sensor joint 40 always faces upwards during assembly.

According to an optional embodiment of the present invention, the three-way joint 1 is a metal piece. The three-way joint 1 is a metal piece, the metal piece is not easy to damage, the use is more convenient, and the effect is better.

Further, the three-way joint 1 is a No. 45 steel piece. That is to say, three way connection 1 adopts 45 steel, and 45 steel price is lower, can reduce the cost of manufacture, and the cost reduction is about 35%, also can make contributions to pipeline system and whole car assembly like this.

Alternatively, as shown in fig. 1 and 2, the outer periphery of the tube bundle joint 20 is provided with a plurality of axially spaced apart retaining rings 21. Be provided with a plurality of axial interval distribution's spacing ring 21 in tube bank joint 20's periphery, after tube bank joint 20 is connected with the tube bank, spacing ring 21 can with the spacing cooperation of tube bank inner wall to can make the riveting between tube bank joint 20 and the tube bank connect more fixedly. For example, the periphery of the tube bundle joint 20 can be provided with three spacing rings 21, the structure of the three spacing rings 21 is the same, and the spacing distance between two adjacent spacing rings 21 is the same, so that the three spacing rings 21 can effectively limit different positions of the tube bundle, and thus, when the tube bundle is riveted with the tube bundle joint 20, the connection stability between the tube bundle and the tube bundle joint can be ensured.

Of course, as shown in fig. 1 and 2, the valve body joint 30 is provided at its outer periphery with a plurality of spacing rings 21 spaced apart from each other, and at its end remote from the joint body 10 with a spacing groove 31. The periphery of the valve body connector 30 is also provided with a plurality of spacing rings 21 which are distributed at intervals, one end far away from the connector main body 10 is provided with a spacing groove 31, and after the valve body connector 30 is connected with the valve body or the air cylinder, the spacing rings 21 and the spacing groove 31 can be in spacing fit with the inner wall of the valve body or the air cylinder, so that the valve body connector 30 and the valve body or the air cylinder can be connected more fixedly.

In addition, as shown in fig. 1 and 2, the ends of the tube bundle joint 20 and the valve body joint 30 distal from the joint body 10 are each provided as a tapered end 22 of decreasing cross-sectional area in a direction distal from the joint body 10. The end of the tube bundle connector 20 and the valve body connector 30 far away from the connector main body 10 are both arranged into a tapered end 22 with the cross sectional area decreasing in the direction far away from the connector main body 10, and the tapered end 22 has a guiding function, so that the tube bundle connector 20 and the valve body connector 30 can be connected with a tube bundle and a valve body or an air storage cylinder more simply and conveniently.

In accordance with an alternative embodiment of the present invention, as shown in fig. 1 and 2, the axial length of the sensor fitting 40 is less than the axial length of the tube bundle fitting 20 and less than the axial length of the valve body fitting 30. Since the tube bundle connector 20 and the valve body connector 30 need to be plugged into the tube bundle and the valve body or the air cylinder, a sufficient axial length is required for convenient plugging, and the sensor is directly connected to the sensor connector 40, the axial length of the sensor connector 40 does not need to be very long, and therefore, the axial length of the sensor connector 40 is smaller than the axial length of the tube bundle connector 20 and the valve body connector 30.

Alternatively, as shown in fig. 1 and 2, the three-way joint 1 is an integrally formed joint. Set up three way connection 1 into integrated into one piece and connect, need not set up to a plurality of parts, can be more convenient when making three way connection 1 like this, can avoid the operation of multistep moreover, make the operation simplify.
