DETAILED DESCRIPTION

[0020] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0021] See also Figure 1-5 The utility model provides a technical solution: a cooling water circuit quick-change connector, including a three-way pipe 1 and a mounting mechanism 3, the outer wall of the three-way pipe 1 is fixedly mounted with a connecting cylinder 2 and communicated with the inside thereof, a circular cavity is opened inside the connecting cylinder 2, a sealing plug 4 is arranged in the circular cavity, the mounting mechanism 3 is placed on the connecting cylinder 2, the mounting mechanism 3 includes a mounting piece A31, a rectangular bayonet 32, a clamping block 33, a mounting piece B34, a rectangular mounting opening 35 and a mounting cavity 36, the number of clamping blocks 33 Four groups of rectangular bayonet holes 32 are arranged in a ring shape on the outer wall of the connecting cylinder 2. The block 33 is fixedly connected to the connecting cylinder 2. The cross-section of the block 33 is a triangle. The outer wall of the mounting piece A31 is provided with four groups of rectangular bayonet holes 32 arranged in a ring shape. The four groups of block 33 and the four groups of rectangular bayonet holes 32 correspond to each other and are connected. The inner wall of the mounting piece B34 contacts the outer wall of the sealing plug 4 and is connected and installed. The outer wall of the mounting piece A31 is provided with two groups of rectangular installation openings 35 arranged front and back. The mounting piece B34 is connected and installed in the rectangular bayonet hole 32. 35, a mounting cavity 36 is provided on the mounting piece A31, and the mounting cavity 36 is connected with the rectangular bayonet 32 ​​and the rectangular mounting hole 35, and the two ends of the three-way pipe 1 are respectively connected with the pipes of the cooling system. When the cooling system needs to be maintained, the mounting piece A31 can be held and slowly pulled downward. Because the cross-sectional shape of the clamping block 33 is a triangle, the clamping block 33 slowly separates from the rectangular bayonet 32 ​​on the mounting piece A31, so that the mounting piece A31 is separated from the connecting cylinder 2, and the sealing plug 4 is also separated from the connecting cylinder 2 along with the mounting piece A31, so that the sealing plug 4 and the connecting cylinder 2 can be installed and disassembled conveniently. After installation, the connecting cylinder 2 can be blocked to ensure its sealing and avoid cooling water leakage. After disassembly, it is convenient to maintain the cooling system, reduce blockage, extend the service life of the three-way pipe 1, and then extend the service life of the new energy battery. The mounting piece A31, the clamping block 33 and the mounting piece B34 are made of plastic material, have a certain elasticity, and are convenient for installation and disassembly.

[0022] Both ends of the three-way pipe 1 are fixedly connected with threaded connecting sleeves, and two groups of sealing rings 5 ​​and one group of sealing rings 6 are fixedly installed in the circular cavity. The sealing ring 6 is located in the middle of the two groups of sealing rings 5. The outer wall of the sealing plug 4 fits tightly with the sealing rings 5 ​​and 6. The outer wall of the sealing plug 4 is provided with an annular groove that engages with the mounting piece B34, and the bottom of the sealing plug 4 is provided with a blind hole 7 to save raw materials.

[0023] Working principle: Connect the two ends of the three-way pipe 1 to the pipes of the cooling system respectively. When the cooling system needs to be maintained, hold the mounting piece A31 and slowly pull it downward. Since the cross-section of the block 33 is a triangle, the block 33 slowly disengages from the rectangular bayonet 32 ​​on the mounting piece A31, so that the mounting piece A31 is separated from the connecting cylinder 2, and the sealing plug 4 is also separated from the connecting cylinder 2 along with the mounting piece A31.

Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
