[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model. However, it should not be construed as a limitation on the protection scope of the present utility model.

[0026] Referring to Figures 1 - 6 , an automotive air-conditioning pipeline joint in an embodiment of the present utility model includes two adjacent connecting pipes 1. At one end of each of the two connecting pipes 1 facing each other, a connecting plate 4 in the shape of a ring structure is fixedly connected. On one side of each of the two connecting plates 4 facing each other, a sealing gasket 5 is fixedly connected. A first joint member 2 is jointly and fittingly sleeved on the tops of the two connecting plates 4, and a second joint member 3 is jointly and fittingly sleeved on the bottoms of the two connecting plates 4. The first joint member 2 and the second joint member 3 are symmetrically arranged up and down, and the connections at both ends of the first joint member 2 and the second joint member 3 are fixedly connected through a connecting component; the connecting component includes a first fixing plate 7 fixedly connected to the outside of the second joint member 3, a second fixing plate 8 fixedly connected to the outside of the first joint member 2 and fittingly contacting the first fixing plate 7, a positioning plate 9 rotatably connected to the outside of the first fixing plate 7 and arranged in an L-shaped structure; and two bolts 10 for fixedly connecting the positioning plate 9 and the second fixing plate 8.

[0027] Specifically, the connecting plates 4 between the two connecting pipes 1 are in contact with each other, causing the sealing gaskets 5 to contact. The first joint member 2 and the second joint member 3 are respectively installed on the top and bottom of the connecting plates 4. Rotate the positioning plate 9 so that the folded edge of the positioning plate 9 fits against the second fixing plate 8. The bottom of the bolt 10 is sequentially screwed into the interiors of the positioning plate 9 and the second fixing plate 8, and the fixed connection operation between the first fixing plate 7 and the second fixing plate 8 can be completed. Thus, the connection work between the first joint member 2 and the second joint member 3 can be completed, and the quick docking work of the connecting pipes 1 can be completed. The structure is simple, the operation is convenient, the assembly efficiency and the convenience of maintenance and replacement can be improved, and the connection is firm and the sealing effect is good, which is beneficial to effectively preventing leakage problems at the pipeline connection, and has strong practicability.

[0028] Referring to Figure 3 , a plurality of protrusions 6 are equidistantly arranged on one side of the first joint member 2 and the second joint member 3 that are in contact with the corresponding connecting plates 4, and the distance between the endpoints of the opposite protrusions 6 is slightly smaller than the distance between the two sides of the two connecting plates 4 that are away from each other. Specifically, when the first joint member 2 and the second joint member 3 cover the outside of the connecting plates 4, the two connecting plates 4 can be better pushed to move towards each other under the action of the protrusions 6, and under the action of the elastic sealing gasket 5, the sealing gasket 5 between the connecting plates 4 can be made to fit more tightly, thereby ensuring the stability of the connection between the two connecting pipes 1.

[0029] The bolt 10 is threadedly connected inside the positioning plate 9, and the bottom of the bolt 10 is threadedly connected to the second fixing plate 8. Specifically, the bolt 10 is commonly threaded inside the positioning plate 9 and the second fixing plate 8, which can ensure the stability of the connection between the positioning plate 9 and the second fixing plate 8.

[0030] Refer to Figure 4 、 Figure 5 and Figure 6 As shown, anti-loosening components for preventing the bolt 10 from loosening are provided on the outer sides of both positioning plates 9. The anti-loosening components include a clamping plate 11 provided on the top of the positioning plate 9 and fitting against the outer side of the bolt 10, a plurality of first bending portions 12 formed on the outer side of the clamping plate 11, and a plurality of second bending portions 13 formed on the outer side of the clamping plate 11 and opposite to the first bending portions 12. The clamping plate 11 is arranged in a U-shape and fits against the top of the positioning plate 9. The bottoms of the plurality of first bending portions 12 all fit against the bottom of the positioning plate 9. One ends of the plurality of second bending portions 13 opposite to the clamping plate 11 all fit against the side of the positioning plate 9 close to the first joint member 2. Specifically, the U-shaped clamping plate 11 is snapped onto the top of the positioning plate 9 and its two ends fit against both sides of the positioning plate 9. After the first bending portions 12 are bent to fit against the bottom of the positioning plate 9, the second bending portions 13 are bent to fit against the side of the positioning plate 9 close to the first joint member 2. Thus, the clamping plate 11 can be fixed on one side of the bolt 10. The clamping plate 11 that fits against the outer side of the bolt head can limit the bolt head, thereby avoiding the problem that the bolt 10 loosens due to the long-term vibration of the vehicle and affecting the connection stability between the first joint member 2 and the second joint member 3.

[0031] Refer to Figure 4 and Figure 6 As shown, hexagonal grooves 14 are provided inside the tops of the four bolts 10. The hexagonal grooves 14 can be used in cooperation with an external hexagonal wrench, so as to facilitate the rotation operation of the bolt 10 with a wrench of a smaller volume in a space with limited installation position.

[0032] Refer to Figure 5 As shown, the positioning plate 9 is hinged and rotatable with the first fixing plate 7. The positioning plate 9 connected by the hinge rotates flexibly, and at the same time is stably connected to the first fixing plate 7 to ensure the connection effect between the first joint member 2 and the second joint member 3.

[0033] Working principle: The connecting plate 4 between the two connecting pipes 1 fits together so that the gasket 5 comes into contact. The first joint 2 and the second joint 3 are respectively installed on the top and bottom of the connecting plate 4. Rotate the positioning plate 9 so that the folded edge of the positioning plate 9 fits with the second fixing plate 8. The bottom of the bolt 10 is screwed into the interiors of the positioning plate 9 and the second fixing plate 8 in sequence, and the fixed connection operation between the first fixing plate 7 and the second fixing plate 8 can be completed. Thus, the connection between the first joint 2 and the second joint 3 can be achieved, and the quick docking work of the connecting pipe 1 can be completed. The structure is simple and the operation is convenient, which can improve the assembly efficiency and the convenience of maintenance and replacement. Moreover, the connection is firm and the sealing effect is good, which is beneficial to effectively prevent the leakage problem at the pipe connection, and has strong practicability;

[0034] Then, the U-shaped clamping plate 11 is clamped on the top of the positioning plate 9 and both ends are made to fit with the two sides of the positioning plate 9. After bending the first bending part 12 to fit with the bottom of the positioning plate 9, bend the second bending part 13 to fit with the side of the positioning plate 9 close to the first joint 2. Thus, the clamping plate 11 can be fixed on one side of the bolt 10. The clamping plate 11 that fits with the outer side of the head of the bolt 10 can limit the head of the bolt 10, so as to avoid the problem that the bolt 10 becomes loose due to the long-term vibration of the vehicle and affects the connection stability between the first joint 2 and the second joint 3.

[0035] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can also be made without departing from the gist of the present invention.
