[0030] Prior art: When a water pump is connected to a water pipe, it is installed through a flange and multiple sets of bolts.

[0031] Technical problem discovered by the utility model inventor: Currently, most water pumps on the market are connected to water pipes directly through threads. During the connection process, it is necessary to knock on the fastening ring, which is time-consuming and labor-intensive, and can easily damage the connecting threads and cause the position of the water pipe to shift. Not only is the connection speed slow, but it also affects the tightness after connection.

[0032] like Figure 1-Figure 6 As shown, a water pump conveniently and tightly connected to a water pipe comprises a main body 1, a sealing ring 2 is fixedly connected to the inner wall of the main body 1, the outer wall of the main body 1 fits the water pipe 3, the outer wall of the main body 1 is provided with a mounting structure 4 for mounting the water pipe 3, the outer wall of the main body 1 is provided with a cleaning structure 5, and the mounting structure 4 comprises:

[0033] A fixed block 41, the outer wall of the main body 1 is fixedly connected to the fixed block 41, the outer wall of the fixed block 41 is fixedly connected to a fixed rod 42, one end of the fixed rod 42 away from the fixed block 41 is fixedly connected to a semicircular block 43, and the outer wall of the fixed rod 42 is slidably connected to a movable block 44;

[0034] A slot 45 is formed on one end of the movable block 44 close to the semicircular block 43, and a movable rod 46 is fixedly connected to one end of the movable block 44 away from the slot 45, and the outer wall of the movable rod 46 passes through the fixed block 41;

[0035] The mounting block 47 is fixedly connected to the outer wall of the water pipe 3, the inner wall of the mounting block 47 is fixedly connected to the return spring 48, the end of the return spring 48 away from the mounting block 47 is fixedly connected to the clamping block 49, and the inner wall of the mounting block 47 is slidably connected to the clamping block 49.

[0036] Specifically, the main body 1 plays a fixing role on the fixed block 41, the fixed block 41 plays a fixing role on the fixed rod 42, the fixed rod 42 plays a fixing role on the semicircular block 43, the end of the semicircular block 43 away from the fixed rod 42 is an arc surface, and the size of the semicircular block 43 is adapted to the size of the slot 45, the movable block 44 can slide along the outer wall of the fixed rod 42, and the end of the movable block 44 away from the slot 45 is an arc surface, the water pipe 3 plays a fixing role on the mounting block 47, and the mounting block 47 will move with the movement of the water pipe 3 The mounting block 47 fixes the return spring 48, and the return spring 48 can push the block 49 to move away from the return spring 48 by its own elastic force. At the same time, when the semicircular block 43 moves in the direction of the inclined surface of the block 49, the inclined surface of the block 49 will be squeezed by the semicircular block 43, so that the block 49 will retract into the mounting block 47. When the plane of the block 49 fits with the plane of the semicircular block 43, the semicircular block 43 is fixed and limited by the block 49, so that the water pipe 3 and the main body 1 are connected together.

[0037] like Figure 6 As shown, an auxiliary rod 410 is fixedly connected to the outer wall of the main body 1 , and a support plate 411 is fixedly connected to one end of the auxiliary rod 410 away from the main body 1 , and one end of the support plate 411 away from the auxiliary rod 410 fits the water pipe 3 and the main body 1 .

[0038] Specifically, the main body 1 fixes the auxiliary rods 410. At the same time, two groups of auxiliary rods 410 are provided, and the two groups of auxiliary rods 410 are symmetrically distributed with the center line of the main body 1 as the symmetry axis. The auxiliary rods 410 fix the support plate 411. At the same time, the support plate 411 is fixedly connected to the two groups of auxiliary rods 410, and the support plate 411 can support the bottom of the connection between the water pipe 3 and the main body 1, thereby avoiding angle deviation when the main body 1 is connected to the water pipe 3.

[0039] like Figure 4 As shown, the cleaning structure 5 includes: a support rod 51, and the inner wall of the main body 1 is fixedly connected with the support rod 51.

[0040] Specifically, the main body 1 plays a role in fixing the support rod 51 .

[0041] like Figure 6 As shown, one end of the support rod 51 away from the main body 1 is fixedly connected with a ring 52 .

[0042] Specifically, the support rod 51 supports the circular ring 52 , thereby preventing the circular ring 52 from being suspended in the air. Meanwhile, the diameter of the circular ring 52 is smaller than the inner diameter of the water pipe 3 .

[0043] like Figure 6 As shown, a cleaning brush 53 is fixedly connected to the outer wall of the ring 52 .

[0044] Specifically, the ring 52 supports the cleaning brush 53 , thereby preventing the cleaning brush 53 from being suspended in the air.

[0045] like Figure 6 As shown, the outer wall of the cleaning brush 53 fits the water pipe 3 .

[0046] Specifically, the inner wall of the water pipe 3 can be cleaned by the cleaning brush 53, thereby preventing dust from being present at the connection between the water pipe 3 and the main body 1 and affecting the tightness of the connection.

[0047] like Figure 6 As shown, there are multiple groups of cleaning brushes 53 , and all are arranged on the outer wall of the ring 52 , and the multiple groups of cleaning brushes 53 are distributed in a circle with the midpoint of the ring 52 as the center.

[0048] Specifically, by providing multiple groups of cleaning brushes 53, the cleaning brushes 53 can perform all-round cleaning on the inner wall of the water pipe 3, thereby further preventing dust from affecting the tightness of the connection between the water pipe 3 and the main body 1.

[0049] It is worth noting that, in order to facilitate control, a sealing ring 2 is fixedly connected to the inside of the main body 1 in this embodiment, and the sealing ring 2 seals the connection between the main body 1 and the water pipe 3. The main function of the sealing ring 2 is to prevent external substances (such as liquid, gas, dust, moisture, etc.) from entering the key parts of the machine and equipment to ensure the normal operation of the machine or equipment, while avoiding leakage and loss of internal liquid or gas. The above are all existing technologies and are not the main innovation points, and will not be described in detail here.

[0050] The working principle of the utility model is as follows:

[0051] By placing the water pipe 3 on the support plate 411 and moving the water pipe 3 toward the main body 1, the water pipe 3 will move horizontally along the outer wall of the support plate 411 toward the main body 1, thereby avoiding angle deviation during installation. At the same time, the mounting block 47 will move toward the main body 1 along with the movement of the water pipe 3. At this time, the semicircular block 43 will be inserted into the mounting block 47. At this time, the inclined surface of the clamping block 49 will be squeezed by the semicircular block 43, so that the clamping block 49 will retract into the mounting block 47. When the water pipe 3 is fitted with the main body 1, the semicircular block 43 will move to the innermost end of the mounting block 47. At this time, the semicircular block 43 will no longer squeeze the clamping block 49. At this time, the clamping block 49 will be reset by the reset spring The elastic force of 48 is used to reset, so that the plane of the block 49 is fitted with the plane of the semicircular block 43, and the semicircular block 43 is fixed and limited by the block 49, so that the water pipe 3 and the main body 1 are connected together. At the same time, when the water pipe 3 needs to be removed, it is only necessary to move the movable rod 46. At this time, the movable block 44 will move with the movement of the movable rod 46, and then the movable block 44 squeezes the inclined surface of the block 49 to make the block 49 retract into the installation block 47 again. At this time, the movable block 44 will continue to move until the slot 45 covers the semicircular block 43. At this time, the block 49 will still be blocked by the outer wall of the movable block 44, and the water pipe 3 and the main body 1 can be easily separated.

[0052] At the same time, when the water pipe 3 moves toward the direction of the main body 1, the inner wall of the water pipe 3 will fit with the outer wall of the cleaning brush 53, and then the dust at the connection between the water pipe 3 and the main body 1 will be cleaned by the cleaning brush 53, so that the dust is swept away, thereby avoiding the existence of a gap at the connection between the water pipe 3 and the main body 1, thereby improving the tightness of the connection between the main body 1 and the water pipe 3.

[0053] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
