[0021] The utility model is further described in detail below through the drawings and embodiments.

[0022] like Figure 1 As shown: a matching joint for a forest fire pump, a connecting pipe 3 is provided at the end of the water inlet 2 of the pump body 1, and the connecting pipe 3 is connected to an external water pipe 12 through a matching joint.

[0023] like Figure 2As shown: the matching joint is located at the end of the connecting pipe 3 and the external water pipe 12 at opposite positions, wherein the connecting pipe 3 can be inserted into the connecting pipe 3. The matching joint includes an annular end seat 4, and a plurality of snap-in grooves 5 are provided in the circumference of the annular end seat 4. The external water pipe 12 is provided with a snap-in structure corresponding to the snap-in grooves 5 in the circumference near the end position, so as to form an axial restraining force between the connecting pipe 3 and the external water pipe 12. A snap-in 6 is provided on the annular end seat 4, and a snap-in seat 7 (which can be plug-in) is movably connected to the corresponding position of the external water pipe. When the snap-in seat 7 is snapped into the snap-in 6, a circumferential restraining force is formed between the connecting pipe 3 and the external water pipe 12. The snap-in structure can retract when subjected to radial force. Therefore, the two can be separated and disassembled by removing the snap-in seat 7 and relatively twisting the external water pipe 12.

[0024] The inner circumference of the annular end seat 4 is larger than the inner circumferential dimension of the connecting pipe 3, so that the external water pipe 12 can be accommodated. The distance between the outer wall of the holder 7 and the end of the external water pipe 12 is larger than the width of the annular end seat 4, so that the external water pipe 12 can be inserted into the connecting pipe 3 for communication.

[0025] like Figure 2-4 As shown in the figure: the clamping structure includes a connection block 8 and an inserting block 9. There is a radial spacing between the inserting block 9 and the clamping block, and a spring 10 is arranged between the two, so that the inserting block 9 can squeeze the clamping block to shrink inwards. Figure 4 As shown, after the inserting block 9 is inserted into the clamping groove 5 , a surplus in the circumferential dimension is formed, and when the inserting block 9 is pressed to fit the connecting block 8 , it can completely detach from the clamping groove 5 .

[0026] Taking the screwing method into consideration, in order to enable the plug block 9 to be subjected to force in a rotational manner and thus be pressed downward, the edge position of the plug block 9 is set to have a chamfer 11, so that after the rotational force is applied, the plug block 9 can quickly disengage from the inner wall position of the clamping groove 5, thereby preventing the connecting pipe 3 from being stuck when rotating.

[0027] like Figure 5 As shown: the plug block 9 cooperates with the spring 10 to block the connecting pipe 3 to form an axial limiting force, but the spring 10 itself is also easy to bend. Therefore, a top block 13 is connected to one side of the connecting block 8. The upper end of the top block 13 just abuts against the rear side of the plug block 9 and will not be placed in the clamping groove 5 to provide horizontal buffering force for the plug block 9.

[0028] The above-mentioned embodiments are for inspiration. Through the above-mentioned description, relevant staff can make various changes and modifications without departing from the scope of the invention. The technical scope of this new type of use is not limited to the content in the specification, and its protection scope must be determined according to the scope of the claims.
