All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0053] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. 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.

[0054] The server provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0055] Example 1:

[0056] like Figures 1 to 2 As shown, this application embodiment provides an engine water pump that is easy to disassemble and assemble, including a pump body 101, a pump cover 102 and a guide plate 103, and also includes a plurality of screw holes 104, which are spaced apart along the edge on the pump cover 102; a plurality of quick-release units 2 are spaced apart on the guide plate 103 for detachable connection with the corresponding screw holes 104.

[0057] Furthermore, the quick-release unit 2 includes a transverse slide groove 201, which is disposed on the surface of the guide plate 103 facing the pump cover 102; a pair of transverse sliding plates 202, which can be slidably mounted at both ends of the transverse slide groove 201 relative to each other; a pair of clamping plates 203, which are respectively fixed to the end surfaces of the pair of transverse sliding plates 202 facing the pump cover 102; and a moving device 3, which is used to control the movement of the pair of transverse sliding plates 202 and the corresponding clamping plates 203.

[0058] Furthermore, the quick-release unit 2 also includes several return springs 204, which are respectively set between the two ends of the horizontal slide groove 201 and the ends of the corresponding horizontal sliding plate 202; several horizontal through grooves 205, which pass through each horizontal sliding plate 202 vertically; and several anti-detachment bolts 206, which pass through each horizontal through groove 205 and are fixed to the guide plate 103 through the screw hole 2.

[0059] In this embodiment of the application, due to the above-described structure, when installing the guide plate 103, several pairs of transverse sliding plates 202 on it are respectively aligned with the screw holes 104 on the pump cover 102. Then, the guide plate 103 and the pump cover 102 are closed, so that each pair of clamping plates 203 are respectively inserted into the corresponding screw holes 104. Then, each pair of clamping plates 203 are opened by each moving device 3. Correspondingly, each transverse sliding plate 202 also slides to the adjacent end of the corresponding transverse sliding groove 201. Each return spring 204 is compressed and shortened, so that the surface of each clamping plate 203 abuts against the screw holes 104, thus completing the installation and fixing of the guide plate 103 and the pump cover 102.

[0060] When disassembling the guide plate 103, operate each moving device 3 to release the support of the corresponding clamp 203. Each return spring 204 releases its elastic potential energy, causing each corresponding transverse sliding plate 202 to slide in the corresponding transverse sliding groove 201 and move closer to each other. Each clamp 203 disengages from the threaded contact of the inner surface of the corresponding screw hole 104, and the guide plate 103 can then be removed.

[0061] Each clamping plate 203 has a groove on its surface that corresponds to the corresponding screw hole 104, ensuring that each clamping plate 203 and the thread in the corresponding screw hole 104 are tightly fitted.

[0062] Example 2:

[0063] like Figures 2 to 3 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the moving device 3 includes a circular groove 301, which is disposed on the outer surface of the pump cover 102; a rotating ring 302, which is rotatably mounted in the circular groove 301; a sliding hole 303, whose two ends connect the middle of the transverse sliding groove 201 and the center of the circular groove 301; a sliding rod 305, which is slidably mounted between the sliding hole 303, the inner ring of the rotating ring 302 and a pair of clamping plates 203; and a transmission component 4, which is used to drive the sliding rod 305 and the rotating ring 302 to extend and retract when the rotating ring 302 rotates.

[0064] Preferably, an expansion cavity is formed between the adjacent sidewalls of a pair of clamping plates 203, and the diameter of the expansion cavity near the end of the circular groove 301 is larger than the diameter of the other end.

[0065] Furthermore, the slide bar 305 includes a transmission section 3051, which can slide between the rotating ring 302 and the sliding hole 303; a support section 3052, which is in the shape of an equilateral trapezoid and can slide between the expansion cavity and the sliding hole 303; and a connecting section 3053, which is used to fix the transmission section 3051 and the support section 3052 to each other and can slide in the sliding hole 303. The cross-sections of the connecting section 3053 and the sliding hole 303 are polygonal, and the minimum diameter is also greater than the maximum width of the cross-sections of the transmission section 3051 and the support end.

[0066] Furthermore, the transmission component 4 includes a plurality of transmission sliders 401, which are fixedly connected at intervals to the outer wall of the transmission section 3051; and a plurality of transmission arc grooves 402, which are spirally distributed at intervals on the inner ring of the rotating ring 302, with each transmission slider 401 slidingly engaging with the corresponding transmission arc groove 402.

[0067] In this embodiment of the application, due to the above-described structure, when it is necessary to spread apart a pair of adjacent clamping plates 203, the rotating ring 302 is rotated, and each transmission slider 401 slides from one end of the corresponding transmission arc groove 402 near the sliding hole 303 to the other end, so that the support section 3052 of the slide rod 305 is fully inserted into the expansion cavity, spreading apart a pair of clamping plates 203. At the same time, part of the transmission section 3051 enters the sliding hole 303, and the connecting section 3053 slides to the end of the sliding hole 303 adjacent to the expansion cavity and abuts against a pair of clamping plates 203.

[0068] When it is necessary to close a pair of clamping plates 203, the rotating ring 302 is rotated in the opposite direction. Each transmission slider 401 slides from the end of the corresponding transmission groove 402 away from the sliding hole 303 to the end closer to the sliding hole 303, so that the support end of the slide rod 305 is retracted into the sliding hole 303, while the transmission section 3051 is completely inserted into the inner ring of the rotating ring 302. At this time, under the action of each return spring 204, the corresponding transverse sliding plate 202 and the corresponding clamping plate 203 move closer to each other.

[0069] Example 3:

[0070] like Figures 2 to 3 As shown, in this embodiment, in addition to the structural features included in the foregoing embodiments,

[0071] Furthermore, the moving device 3 also includes several arc-shaped through grooves 306, which are spaced apart on the rotating ring 302 in the circumferential direction; and several locking bolts 307, which pass through the corresponding arc-shaped through grooves 306 and are fixed to the guide plate 103 through the corresponding screw holes.

[0072] Furthermore, the moving device 3 also includes a number of blind holes 308, which are spaced apart circumferentially on the inner surface of the circular groove 301; a number of floating plates 309, which can be floated in the corresponding blind holes 308 by corresponding floating springs 310; and a number of insert blocks 311, which are fixed to each floating plate 309 and can be inserted into the corresponding arc groove.

[0073] Furthermore, the moving device 3 also includes a plurality of external holes 312, which are spaced circumferentially on the outer surface of the ring 302.

[0074] In this embodiment of the application, due to the above-described structure, before the rotating ring 302 causes the support section 3052 to fully enter the expansion cavity, each floating spring 310 is compressed and shortened, and the outer end face of each insert 311 abuts against the surface of the rotating ring 302. After the support section 3052 fully enters the expansion cavity, each locking bolt 307 abuts against one end of the corresponding arc groove 306, and the other end of these arc grooves 306 corresponds to each blind hole 308. At this time, each floating spring 310 releases elastic potential energy, pushing each floating plate 309 and the corresponding insert 311 closer to the corresponding arc groove 306 until the outer wall of each floating plate 309 abuts against the outer wall of the ring 302. At this time, each insert 311 is inserted into the end of the corresponding arc groove 306 away from the corresponding locking bolt 307, so that the rotating ring 302 is fixed, and the support section 3052 is fixed.

[0075] When it is necessary to release the fixing of the rotating ring 302, a tool 200 with a number of rods 100 corresponding to the number of inserts 311 and the number of outer holes 312 is used. Part of the rods 100 on the tool 200 are inserted into the corresponding arc-shaped through grooves 306, and the other rods 100 are inserted into the outer holes 312. Each insert 311 is pushed into the corresponding blind hole 308. The rotating ring 302 can then be rotated by the tool 200, so that the support section 3052 is partially retracted into the sliding hole 303.
