It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0050] The server provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0051] Example 1:

[0052] like Figures 1 to 3 As shown, this application provides an easy-to-install engine water pump, including a water pump housing 1, an inlet pipe 2 and an outlet pipe 3, and a ring cover 4, which is fixed to the outer end of the outlet pipe 3; and a quick-release device 5, which is used to detachably connect the external cooling pipe 200 to the ring cover 4.

[0053] Furthermore, the quick-release device 5 includes several through slots 51, which are radially spaced at the bottom of the side wall of the ring cover 4; several sliding blocks 52, which are driven by the rotation control unit 6 and can be telescopically slidably installed in the corresponding through slots 51; and several support blocks 53, which are respectively fixed to the top of each sliding block 52.

[0054] Furthermore, the rotary control unit 6 includes several connecting grooves 61, which are respectively disposed at the bottom of the outer side of each through groove 51; a rotating ring 62, which is rotatably sleeved on the outer wall of the water outlet pipe 3; and several transmission components 7, which are movably installed in the corresponding connecting grooves 61, for driving the rotating ring 62 to each sliding block 52.

[0055] Furthermore, the transmission component 7 includes a transmission arc groove 71, which is disposed on the rotating ring 62, with one end close to the inner ring of the rotating ring 62 and the other end away from the inner ring of the rotating ring 62; a sliding rod 72, with its upper end fixedly connected to the bottom of the corresponding sliding block 52, its middle part slidingly engaged with the corresponding connecting groove 61, and its lower end slidably installed in the corresponding transmission arc groove 71.

[0056] In this embodiment of the application, due to the above-described structure, when connecting the external cooling pipe 200, it is inserted between the ring cover 4 and each support block 53. Then, the rotating ring 62 is rotated. The rotating ring 62 rotates outside the water outlet pipe 3. Each sliding rod 72 slides from the corresponding transmission arc groove 71 near the inner end of the rotating ring 62 to away from the inner end of the rotating ring 62, and at the same time slides to the outer end of the corresponding connecting groove 61, driving each sliding block 52 and the corresponding support block 53 to slide to the outer end of the corresponding through groove 51, opening up the end wall of the external cooling pipe 200 and clamping it between the inner wall of the ring cover 4 and the outer wall of each support block 53. The outer wall of the external cooling pipe 200 is in close contact and sealed with the inner wall of the ring cover 4.

[0057] When it is necessary to disassemble the external cooling pipe 200, rotate the rotating ring 62 in the opposite direction. The rotating ring 62 rotates outside the water outlet pipe 3. Each sliding rod 72 slides from the corresponding transmission arc groove 71 away from the inner end of the rotating ring 62 to the end close to the inner end of the rotating ring 62, and at the same time slides to the inner end of the corresponding connecting groove 61 until each sliding block 52 is separated from the contact with the inner wall of the end of the external cooling pipe 200, then the external cooling pipe 200 can be removed.

[0058] The external cooling pipe 200 is a rubber hose, which allows it to deform and seal against the inner wall of the ring cover 4.

[0059] Example 2:

[0060] like Figures 1 to 3 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the quick-release device 5 also includes a floating cover 54, which is slidably mounted on the outside of the ring cover 4; a locking member 8, used to lock the floating cover 54 and the rotating ring 62 together; and a resetting member 9, used to apply a force close to the rotating ring 62 to the floating cover 54.

[0061] Furthermore, the engaging component 8 includes a plurality of engaging grooves 81, which are spaced apart circumferentially on the outer ring of the rotating ring 62; and a plurality of engaging blocks 82, which are fixedly connected to the bottom of the floating cover 54 at intervals circumferentially. When the bottom end of the floating cover 54 abuts against the top surface of the rotating ring 62, each engaging block 82 is inserted into the corresponding engaging groove 81.

[0062] Furthermore, the locking component 8 also includes several guide ramps 83, which are symmetrically arranged at both ends of the bottom of each locking block 82.

[0063] In this embodiment of the application, due to the above-described structure, when the end of the external cooling pipe 200 is clamped between the inner wall of the ring cover 4 and the outer wall of each support block 53, each locking block 82 corresponds to the corresponding locking groove 81. Under the action of the reset member 9, the floating cover 54 approaches the rotating ring 62, and each locking block 82 inserts into the corresponding locking groove 81 until the bottom end face of the floating cover 54 contacts the top surface of the rotating ring 62. At this time, each locking block 82 is fully inserted into the corresponding locking groove 81, and the top surface of the floating cover 54 also abuts against the outer wall deformed by each support block 53, forming a seal again. At this time, the rotating ring 62 cannot rotate, and the end of the external cooling pipe 200 is completely fixed between the ring cover 4, each support block 53 and the floating cover 54.

[0064] When it is necessary to disassemble the external cooling pipe 200, the rotating ring 62 can only be rotated after the floating cover 54 is manually pushed to disengage each locking block 82 from the corresponding locking groove 81, so that each support block 53 is disengaged from the inner wall of the end of the external cooling pipe 200, and the external cooling pipe 200 can be disengaged from the ring cover 4, each support block 53 and the floating cover 54.

[0065] Example 3:

[0066] like Figures 1 to 3 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the reset member 9 includes a plurality of communicating arc grooves 91, which are distributed circumferentially on the rotating ring 62 and are concentric with the rotating ring 62; a plurality of connecting rods 92, which are fixed to the inner wall of the floating cover 54 and can slide through each communicating arc groove 91 and extend to the bottom of the rotating ring 62; and a plurality of elastic members 10, which are used to make each connecting rod 92 slide away from the rotating ring 62.

[0067] Furthermore, the elastic element 10 includes several baffles 101, which are fixedly connected to the lower end of each connecting rod 92; and several springs 102, which are respectively sleeved on the outside of each connecting rod 92, with their upper ends abutting against the bottom surface of the rotating ring 62 and their lower ends abutting against the corresponding baffles 101.

[0068] Furthermore, the reset component 9 also includes several vertical grooves 93, which are spaced circumferentially on the outer wall of the ring cover 4, and each connecting rod 92 slides in cooperation with the corresponding vertical groove 93.

[0069] In this embodiment of the application, due to the aforementioned structure, while the rotating ring 62 rotates, each connecting rod 92 slides in the corresponding connecting arc groove 91. At this time, each engaging block 82 does not correspond to the corresponding engaging groove 81, and each spring 102 is compressed, applying force to the rotating ring 62 to provide damping force. This prevents the rotating ring 62 from reversing due to a failure to rotate to the designated position, until the external cooling pipe 200 is fixed between the ring cover 4 and each support block 53. When each locking block 82 corresponds to the corresponding locking groove 81, each spring 102 releases elastic potential energy, and cooperates with the corresponding baffles 101 and connecting rods 92 to pull the floating cover 54 closer to the rotating ring 62, so that each locking block 82 is inserted into the corresponding locking groove 81. Since each connecting rod 92 can slide with the corresponding vertical groove 93, the floating cover 54 cannot rotate around the ring cover 4, thus restricting the circumferential degree of freedom of the rotating ring 62 when each locking groove 81 and the corresponding locking block 82 are locked together.
