[0012] A third through hole is formed on the top of the main body. When the connecting block is located in the first placement groove, the interior of the second through hole is connected to the interior of the third through hole.

[0013] In a preferred example, the utility model can be further configured as follows: the upper half of the vertical cross section of the third through hole is a bell mouth.

[0014] In a preferred example, the utility model can be further configured as follows: a screw tube is provided on the connecting head, the screw tube is threadedly connected to the connecting head, and as the screw tube rotates, the screw tube covers the third through hole.

[0015] In summary, the present invention includes at least one of the following beneficial technical effects:

[0016] 1. By dividing the connector body into two parts, namely, the main body and the connecting head, and the connecting head is detachably connected to the main body, it is convenient for operators to quickly remove the damaged main body part, shortening the disassembly time and avoiding damage to the air conditioner evaporator during the disassembly process.

[0017] 2. By providing the third through hole and the second through hole, the interior of the second through hole, the interior of the third through hole and the interior of the first through hole are all connected, which is convenient for operators to pour lubricating oil into them and convenient for operators to quickly disassemble the main body.

[0018] 3. By providing a screw tube, the screw tube rotates to cover the bolt hole and the third through hole, thereby preventing dust from entering the third through hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] Example:

[0026] Reference Figure 1-Figure 4As shown, the utility model discloses an inlet and outlet joint on an automobile air-conditioning evaporator, comprising a joint body 1. The joint body 1 comprises a connecting head 11 and a main body 12.

[0027] The arc-shaped end of the connector 11 is welded and fixed to the edge of the air conditioner evaporator. The connector 11 and the main body 12 are detachably connected.

[0028] A connecting block 2 is integrally provided on one side of the connecting head 11 close to the main body 12. A first placement groove 21 is provided on one side of the main body 12 close to the connecting head 11. The connecting block 2 is located in the first placement groove 21. The vertical cross-sectional shape of the connecting block 2 matches the vertical cross-sectional shape of the first placement groove 21. The vertical cross-sectional shape of the connecting block 2 is a square.

[0029] A first through hole 22 is formed on one side of the connection block 2 . The connection block 2 is connected to the first placement groove 21 by bolts, and the bolts pass through the first through hole 22 .

[0030] A second through hole 3 is provided at the top of the connection block 2, and the interior of the second through hole 3 is connected to the interior of the first through hole 22. A third through hole 31 is provided at the top of the main body 12, and when the connection block 2 is located in the first placement groove 21, the interior of the second through hole 3 is connected to the interior of the third through hole 31. The upper half of the vertical section of the third through hole 31 is a bell mouth.

[0031] The connecting head 11 is provided with a screw tube 4 , which is threadedly connected to the connecting head 11 . As the screw tube 4 rotates, the screw tube 4 covers the third through hole 31 .

[0032] The implementation principle of the above embodiment is:

[0033] When the operator connects the connector 11 and the main body 12 together.

[0034] The operator first places the connecting block 2 in the first placement groove 21. The operator then uses bolts to pass through the main body 12 and the connecting block 2, so that the bolts are connected to the main body 12 with bolts.

[0035] Next, the operator rotates the screw tube 4 to start the movement of the screw tube 4. After the screw tube 4 rotates to a proper position, the third through hole 31 and the bolt hole on the main body 12 are covered.

[0036] When the operator needs to remove the main body 12 , the operator rotates the screw tube 4 in the reverse direction to return the screw tube 4 to the initial position, that is, the screw tube 4 is only in contact with the connector 11 .

[0037] The operator uses a tool to rotate the bolt and remove the bolt. In order to facilitate the removal of the bolt, the operator injects lubricating oil into the third through hole 31, and the lubricating oil flows into the first through hole 22 through the third through hole 31 and the second through hole 3.

[0038] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
