DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-8 This application is described in further detail.

[0037] The present application embodiment discloses a coolant pot that is convenient for connecting with a hose. Figure 1 A coolant kettle that is easy to connect with a hose includes a kettle body 1 and a hose 2, a first connecting piece 3 is arranged on the kettle body 1, a second connecting piece 4 is arranged inside the first connecting piece 3, and the kettle body 1 and the hose 2 are connected together through the first connecting piece 3 and the second connecting piece 4.

[0038] Reference Figure 1 and Figure 2 The kettle body 1 comprises an upper kettle body 11 and a lower kettle body 12, and the upper kettle body 11 and the lower kettle body 12 are overlapped with each other, and a liquid storage cavity is formed inside after the upper kettle body 11 and the lower kettle body 12 are overlapped. The upper kettle body 11 is assumed to be the top of the kettle body 1, and the lower kettle body 12 is assumed to be the bottom of the kettle body 1. A liquid filling port 111 is provided on the top of the upper kettle body 11, and two liquid outlets 121 are provided on the lower kettle body 12. Both liquid outlets 121 are provided with a first connecting member 3. In this embodiment, one of the liquid outlets 121 is described in cooperation with the first connecting member 3, and the first connecting member 3 is integrally formed at the open end of the liquid outlet 121.

[0039] Reference Figure 3 The second connecting member 4 includes a fixed sleeve 41 and a matching sleeve 42. The hose 2 extends into the fixed sleeve 41 through the matching sleeve 42. The fixed sleeve 41 and the matching sleeve 42 are both integrally formed with a plurality of equally spaced ears 411. In this embodiment, four equally spaced ears 411 are selected according to the sizes of the fixed sleeve 41 and the matching sleeve 42. The fixed sleeve 41 and the matching sleeve 42 are provided with a total of eight ears 411. Screw holes are opened on the ears 411, and bolts 412 are threadedly connected to the screw holes on the matching sleeve 42.

[0040] Reference Figure 3 and Figure 4 , align the four ears 411 on the fixed sleeve 41 with the four ears 411 on the matching sleeve 42 in pairs, and align the screw holes in pairs, and pass the bolts 412 passing through the screw holes on the matching sleeve 42 through the screw holes of the fixed sleeve 41. One end of the bolt 412 passing through the screw holes on the fixed sleeve 41 is threadedly connected with a fastening nut 413, and the fastening nut 413 is used to adjust the distance between the fixed sleeve 41 and the matching sleeve 42. An anti-vibration ring 414 is sleeved on the bolt 412, and the anti-vibration ring 414 is located between the fastening nut 413 and the fixed sleeve 41, so that the fastening nut 413 is not easily loosened due to vibration, and a locking piece 5 is movably connected between the fixed sleeve 41 and the matching sleeve 42.

[0041] Reference Figure 3 , Figure 4 and Figure 5The locking member 5 includes a second sealing ring 51 which is respectively in contact with the fixed sleeve 41 and the matching sleeve 42. A second annular groove 511 is provided at one end of the second sealing ring 51 close to the hose 2. A barb plate 52 is embedded in the second annular groove 511. The second sealing ring 51 surrounds and fixes the peripheral wall of the barb plate 52. A barb nail 521 is integrally formed at one end of the barb plate 52 close to the hose 2. The distance between the fixed sleeve 41 and the matching sleeve 42 is adjusted by the bolt 412 and the fastening nut 413. When the distance between the fixed sleeve 41 and the matching sleeve 42 is closer and closer by adjusting the bolt 412 and the fastening nut 413, the second sealing ring 51 moves toward the direction of the hose 2 under the pressure of the fixed sleeve 41 and the matching sleeve 42, so that the barb nail 521 is inserted into the hose 2, and the barb nail 521 is inclined toward the direction of the liquid outlet 121, which is conducive to the hose 2 not being easily separated from the fixed sleeve 41 and the matching sleeve 42.

[0042] Reference Figure 6 , Figure 7 and Figure 8 The first connecting member 3 is cylindrical, and an operating groove 31 is opened in the first connecting member 3. The inner diameter of the liquid outlet 121 is smaller than the inner diameter of the operating groove 31, so that an abutting portion 311 abutting against the second connecting member 4 is left at the bottom of the operating groove 31. When the fixed sleeve 41 is inserted into the operating groove 31, one end of the fixed sleeve 41 inserted into the operating groove 31 can abut against the abutting portion 311, so that the position of the fixed sleeve 41 can be limited. A first limiting groove 3111 is opened at the abutting portion 311, and a first limiting block 421 is integrally formed at one end of the fixed sleeve 41 abutting against the abutting portion 311. When the first limiting block 421 is inserted into the first limiting groove 3111, the positioning of the fixed sleeve 41 and the liquid outlet 121 is completed.

[0043] Reference Figure 7 In order to prevent the fixed sleeve 41 from being easily disengaged from the operating groove 31 due to vibration or accidental collision, a second limiting block 422 is integrally formed at a side wall of the first limiting block 421 close to the bottom of the first limiting groove 3111, and a second limiting groove 3112 is provided at a side wall of the first limiting groove 3111 close to the bottom of the groove to cooperate with the second limiting block 422. The first limiting block 421 and the second limiting block 422 are generally in a "T" shape, and the first limiting groove 3111 and the second limiting groove 3112 are also generally in a "T" shape.

[0044] Reference Figure 3 and Figure 8A sealing groove 312 is provided on the inner peripheral wall of the operating groove 31, and a first sealing ring 3121 is placed in the sealing groove 312. The end of the first sealing ring 3121 away from the sealing groove 312 abuts against the fixed sleeve 41, so that the liquid is not easy to overflow from the abutment between the fixed sleeve 41 and the operating groove 31, which is conducive to improving the sealing performance. An annular protrusion 313 is also integrally formed on the inner peripheral wall of the operating groove 31. The annular protrusion 313 is farther away from the bottom of the operating groove 31 than the first sealing ring 3121. A first annular groove 415 is provided on the outer wall of the fixed sleeve 41 to be engaged with the annular protrusion 313. The first annular groove 415 is concave toward the inside of the fixed sleeve 41, so that a protrusion 416 is formed on the inner wall of the fixed sleeve 41, which is beneficial for limiting the hose 2 through the protrusion 416 when the hose 2 is inserted into the fixed sleeve 41. A chamfer is provided on one edge of the first annular groove 415 close to the notch, so that when the first annular groove 415 is engaged with the annular protrusion 313, it can be smoother.

[0045] The installation process of a coolant pot that is easy to connect with a hose in an embodiment of the present application is as follows: the fixing sleeve 41 and the matching sleeve 42 are connected by the bolt 412, and then the end of the fixing sleeve 41 facing away from the matching sleeve 42 is inserted into the installation groove 31. When the first limit block 421 is embedded in the first limit groove 3111 and the second limit block 422 is embedded in the second limit groove 3112, and the annular protrusion 313 is embedded in the first annular groove 415, the connection between the first connecting member 3 and the second connecting member 4 is completed. At this time, the hose 2 is passed through the matching sleeve 42 and inserted into the fixing sleeve 41. When one end of the hose 2 inserted into the fixing sleeve 41 is in contact with the protrusion 416, the barbed nail 521 can be inserted into the outer wall of the hose 2 by adjusting the bolt 412 and the fastening nut 413 to fix the hose 2. If it is necessary to disassemble the hose 2 and the liquid outlet 121, it is only necessary to pull the fixing sleeve 41 with force to pull the fixing sleeve 41 out of the operating groove 31.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
