[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The embodiment of the present application solves the problems in the prior art by providing a fire water pump connector.

[0025] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0026] Embodiment 1:

[0027] The specific structure of this embodiment is as follows: Figure 1-Figure 3 As shown, a fire pump connector comprises:

[0028] The sleeve 3 has a through hole 16 on the left side of the sleeve 3, a first connecting pipe 1 is connected to the left side of the sleeve 3 near the through hole 16, a second connecting pipe 7 is connected to the inside of the sleeve 3, and a limiting plate 6 is fixedly connected to the outer side of the second connecting pipe 7;

[0029] A pair of fixing plates 13 are correspondingly connected to the outer side of the limiting plate 6, and a pinch plate 5 is rotatably connected to the inner side of the fixing plate 13. The shorter arm of the pinch plate 5 is movably connected to the limiting plate 6, and the longer arm of the pinch plate 5 is provided with a limiting mechanism. When connection is required, the end of the pinch plate 5 is pressed downward to make the front end tilt up, and then the end of the second connecting tube 7 is inserted into the sleeve 3, and the end of the second connecting tube 7 is made to contact with the sealing ring 10, and then the pinch plate 5 is released. Under the elastic action of the reset spring 9, the end of the pinch plate 5 is lifted up, so that the front end buckles the limiting plate 6, and the second connecting tube 7 is fixed;

[0030] A sealing ring 10 is connected to the inner wall of the sleeve 3 near the through hole 16 . The sealing ring 10 is provided to increase the sealing effect between the first connecting pipe 1 and the second connecting pipe 7 .

[0031] In some examples, the limiting mechanism includes a groove 12 opened on the outside of the sleeve 3, and a reset spring 9 is fixedly connected to the inside of the groove 12. One end of the reset spring 9 is fixedly connected to the buckle plate 5, and a limiting rod 11 is connected below the buckle plate 5 and on the inner side of the reset spring 9. Under the connecting action of the reset spring 9, it is beneficial to support the end of the buckle plate 5, press the end of the buckle plate 5 downward, squeeze the reset spring 9, so that the front end is tilted, and then the end of the second connecting tube 7 is inserted into the sleeve 3, and the end of the second connecting tube 7 is in contact with the sealing ring 10, and then the buckle plate 5 is released. Under the elastic action of the reset spring 9, the end of the buckle plate 5 is lifted up so that the front end is buckled to the limiting plate 6. By setting the limiting rod 11, it is beneficial to limit the reset spring 9 and prevent it from bending and deformation.

[0032] In some examples, the side panels 4 are connected to both sides of the longer arm of the gusset plate 5, which is beneficial to increase the contact area between the palm of the staff and the gusset plate 5, making it easier to hold.

[0033] In some examples, the side panel 4 is set to an arc shape. When connection is required, the ends of the upper and lower side panels 5 are pressed downward to make the front end tilt up. By setting the side panel 4 to an arc shape, it is convenient for the staff to hold the upper and lower side panels 4 and the buckle plates 5.

[0034] In some examples, a bearing 15 is embedded inside the fixed plate 13, and the inner ring of the bearing 15 is fixedly connected to a shaft 14, and one end of the shaft 14 is fixedly connected to the buckle plate 5. Under the connection between the bearing 15 and the shaft 14, the buckle plate 5 is convenient to flip, and then the angle of the buckle plate 5 is convenient to adjust. The end of the buckle plate 5 is pressed downward to make the front end tilt up, and the buckle plate 5 is released. Under the elastic action of the reset spring 9, the end of the buckle plate 5 is lifted up.

[0035] In some examples, a pair of slots 2 are provided on the outer side of the first connecting pipe 1, and the fire hose is put on the first connecting pipe 1 and fixed by a clamp. The pair of slots 2 facilitates the positioning of the clamp.

[0036] In some examples, a threaded groove 8 is provided on the outer side of the second connecting pipe 7. By providing the threaded groove 8, it is convenient to connect the second connecting pipe 7 to the outlet pipeline of the fire pump.

[0037] By adopting the above technical solution:

[0038] When connection is needed, press the end of the buckle plate 5 downwards to make the front end tilt up, then insert the end of the second connecting tube 7 into the sleeve 3, and make the end of the second connecting tube 7 contact with the sealing ring 10, then release the buckle plate 5, and under the elastic action of the reset spring 9, lift up the end of the buckle plate 5 so that the front end buckles the limit plate 6, completing the fixation of the second connecting tube 7. The operation process is simple and saves installation time.

[0039] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
