[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] like Figure 1-Figure 5As shown, this embodiment provides a water pump stall test tool, including a bracket 1, a mounting assembly 4 and a supply assembly, the mounting assembly 4 is arranged on the bracket 1, the mounting assembly 4 includes a fixed sleeve 42 and a movable sleeve 41, the movable sleeve 41 can slide relative to the bracket 1, the movable sleeve 41 can approach or move away from the fixed sleeve 42, the fixed sleeve 42 and the movable sleeve 41 are both provided with openings, the openings of the fixed sleeve 42 and the movable sleeve 41 are relatively arranged, the water pump 100 is located between the fixed sleeve 42 and the movable sleeve 41 and the two sides of the water pump 100 can abut against the fixed sleeve 42 and the movable sleeve 41, the supply assembly is connected to the joint of the water pump 100, and the supply assembly is used to supply water to the joint. By relatively arranging the fixed sleeve 42 and the movable sleeve 41 on the bracket 1, when testing the water pump 100, the water pump 100 is placed between the opening of the fixed sleeve 42 and the opening of the movable sleeve 41, and then the movable sleeve 41 is slid on the bracket 1, so that the fixed sleeve 42 and the movable sleeve 41 abut against the water pump 100, so that the relative position of the water pump 100 on the bracket 1 is fixed, and after the test is completed, the movable sleeve 41 is slid in the opposite direction on the bracket 1, and the water pump 100 can be directly taken out. The installation and disassembly process is simple to operate, takes less time, and is conducive to improving the test efficiency.

[0032] Furthermore, if Figure 1-Figure 4 As shown, a first slide plate 2 is fixedly connected to the bracket 1, and slideways are arranged on both sides of the first slide plate 2. A slider 3 is slidably connected to the first slide plate 2, and both sides of the slider 3 can cooperate with the slideways on both sides of the first slide plate 2, so that the slider 3 can slide along the first direction. That is, the slider 3 can slide along the length direction of the first slide plate 2, and the length direction of the first slide plate 2 is parallel to the length direction of the bracket 1, so that the slider 3 can slide along the length direction of the bracket 1. A second slide plate 46 is fixedly connected above the slider 3, and the fixed sleeve 42 is fixedly connected to the slider 3 through the second slide plate 46. The movable sleeve 41 is slidably connected to the second slide plate 46, so that the movable sleeve 41 is slidably connected to the slider 3 through the second slide plate 46. The bottom end of the movable sleeve 41 is fixedly connected to a sliding plate 47, and a sliding groove 461 is arranged on the second slide plate 46, and the sliding plate 47 is provided with a protrusion that cooperates with the sliding groove 461, so that the sliding plate 47 is slidably connected to the second slide plate 46, and the sliding plate 47 can slide along the second direction and drive the movable sleeve 41 to slide relative to the second slide plate 46. The first direction and the second direction are arranged at an angle, so that the installation assembly 4 can drive the water pump 100 to translate on the horizontal plane of the bracket 1 through the arrangement of the first slide plate 2 and the second slide plate 46. In this embodiment, the slide groove 461 is arranged along the length direction of the second slide plate 46, and the length direction of the second slide plate 46 is parallel to the width direction of the bracket 1, so that the sliding plate 47 can slide along the width direction of the bracket 1, that is, the first direction and the second direction are perpendicular.

[0033] It should be noted that in this embodiment, the slider 3 slides relative to the first slider 2 and can maintain the position unchanged after sliding, for example, by providing a locking device on the slider 3 or providing a damping member on the sliding pair of the slider 3 and the first slider 2 to increase the damping between the two, etc., and the specific structure is not described here. Similarly, the sliding plate 47 slides relative to the second slider 46 and can maintain the position unchanged after sliding, so that the fixed sleeve 42 and the movable sleeve 41 remain in contact with the water pump 100. The relevant implementation method has been mentioned above, so it will not be repeated.

[0034] Furthermore, if Figure 1 , Figure 2 and Figure 4 As shown, the mounting assembly 4 further includes a side plate 45, a guide rod 44 and a first spring 43. The openings of the fixed sleeve 42 and the movable sleeve 41 are arranged opposite to each other, and the fixed sleeve 42 and the movable sleeve 41 are arranged at intervals along the second direction, i.e., the width direction of the bracket 1. The side plate 45 is fixedly connected to one end of the second slide plate 46 provided with the movable sleeve 41, and is arranged on one side of the back side of the opening of the movable sleeve 41. The first spring 43 is arranged between the side plate 45 and the movable sleeve 41, the axis of the first spring 43 is arranged along the second direction, and the two ends of the first spring 43 are respectively connected to the side plate 45 and the movable sleeve 41. The first spring 43 is always in a compressed state, so that the first spring 43 can make the movable sleeve 41 slide toward the fixed sleeve 42. When the water pump 100 is installed, under the elastic force of the first spring 43, the fixed sleeve 42 and the movable sleeve 41 are both abutted against the two sides of the water pump 100, thereby fixing the water pump 100. The guide rod 44 is coaxially arranged with the first spring 43. The guide rod 44 and the first spring 43 are fixedly connected to the movable sleeve 41 through a connecting piece 411 protruding from the movable sleeve 41. The surface of the connecting piece 411 is a plane, thereby ensuring the connection effect between the guide rod 44 and the first spring 43 and the movable sleeve 41. The other end of the guide rod 44 passes through the side stand plate 45 and is slidably connected to the side stand plate 45.

[0035] Furthermore, the inner side walls of the openings of the fixed sleeve 42 and the movable sleeve 41 are fixedly connected with the lining 48, and the lining 48 covers the inner side walls of the openings of the fixed sleeve 42 and the movable sleeve 41. The lining 48 is preferably a rubber part and is used to abut against the water pump 100. When the first spring 43 pushes the movable sleeve 41 to slide, the lining 48 gradually approaches and contacts the two sides of the water pump 100, and presses the two sides of the water pump 100 under the action of the elastic force of the first spring 43, and abuts against the water pump 100, so that the two sides of the water pump 100 are wrapped by the lining 48, and the relative position of the water pump 100 and the bracket 1 are fixed under the action of friction. In order to strengthen the friction between the lining 48 and the water pump 100, the water pump 100 is made more firmly on the mounting assembly 4. A plurality of anti-slip grooves 481 are arranged at intervals on the side where the lining 48 abuts against the water pump 100. The anti-skid groove 481 is preferably a rectangular groove, and a plurality of anti-skid grooves 481 are evenly arranged along the layout direction of the lining 48 .

[0036] Alternatively, if Figure 1-Figure 4 As shown, the mounting assembly 4 also includes a handle 412, which can be fixedly connected to the movable sleeve 41, or fixedly connected to the guide rod 44. In this embodiment, the handle 412 is preferably fixedly connected to the movable sleeve 41. When installing the water pump 100, the handle 412 is pulled to make the movable sleeve 41 move toward the side plate 45 to overcome the elastic force of the first spring 43, and the distance between the movable sleeve 41 and the fixed sleeve 42 increases. The water pump 100 is placed between the opening of the fixed sleeve 42 and the opening of the movable sleeve 41, and the force applied to the handle 412 is controlled so that the movable sleeve 41 slowly moves toward the fixed sleeve 42 under the elastic force of the first spring 43. Since there is still a certain force on the handle 412 at this time, the movable sleeve 41 will not move quickly toward the fixed sleeve 42 under the elastic force of the first spring 43, thereby preventing the water pump 100 from being damaged by impact. When the lining 48 of the movable sleeve 41 contacts the water pump 100, the handle 412 is released, and the lining 48 abuts against the water pump 100. The installation of the water pump 100 is completed. At this time, the first slide plate 2 and the slider 3 drive the water pump 100 to move along the first direction until the interface of the water pump 100 is aligned with the supply assembly, the supply assembly is connected to the interface of the water pump 100, and a stall test is performed. Due to the arrangement of the first slide plate 2 and the slider 3, when installing the water pump 100, it can be installed first in an area with a larger operating space on the bracket 1. After the installation is completed, the water pump 100 can be moved to the position to be tested by the first slide plate 2 and the slider 3 to reduce the difficulty of operation.

[0037] Furthermore, if Figure 1-Figure 5As shown, the supply assembly includes a water tank 9, a first pipeline 6 and a second pipeline 7. The first pipeline 6 and the second pipeline 7 are both connected to the water tank 9. One of the first pipeline 6 and the second pipeline 7 is connected to the water inlet joint of the water pump 100, and the other is connected to the water outlet joint of the water pump 100. That is, one of the first pipeline 6 and the second pipeline 7 is used to draw water from the water tank 9 and supply it to the water inlet joint of the water pump 100, and the water discharged by the water pump 100 flows back to the water tank 9 through the water outlet joint and the other of the first pipeline 6 and the second pipeline 7. A power supply 200 is also fixedly arranged on the bracket 1, and the power supply 200 is electrically connected to the water pump 100 and is used to supply electric energy to the water pump 100.

[0038] Furthermore, the ends of the first pipeline 6 and the second pipeline 7 connected to the water pump 100 are both set as hoses, and the ends of the first pipeline 6 and the second pipeline 7 are respectively sleeved at the two joints of the water pump 100. In order to reduce the difficulty of connection, the inner diameter of the ends of the first pipeline 6 and the second pipeline 7 is set to be greater than or equal to the diameter of the joint of the water pump 100, so that the first pipeline 6 or the second pipeline 7 can be more easily sleeved on the joint of the water pump 100. The water pump blocking test tool in this embodiment also includes at least two clamping assemblies 5. In this embodiment, the number of the clamping assemblies 5 is preferably two, and the two clamping assemblies 5 are respectively arranged at the ends of the first pipeline 6 and the ends of the second pipeline 7. Both clamps are used to seal the connection positions of the first pipeline 6 and the second pipeline 7 with the water pump 100. In this embodiment, the first pipeline 6 is connected to the water inlet joint of the water pump 100, and the clamp is used to seal the first pipeline 6 and the water inlet joint; the second pipeline 7 is connected to the water outlet joint of the water pump 100, and the clamp is used to seal the second pipeline 7 and the water outlet joint.

[0039] Specifically, Figure 5As shown, the clamping assembly 5 is configured as a clamp-shaped structure as a whole. The clamping assembly 5 includes a hinge shaft 53, a second spring 52 and two cross-arranged clamping arms 51. The clamping arm 51 includes a gripping portion 511, a hinged portion 512 and a clamping portion 513, and the gripping portion 511, the hinged portion 512 and the clamping portion 513 are integrally formed and connected. The clamping portion 513 is configured as an arc structure, and the two clamping portions 513 are arranged opposite to each other. The two hinged portions 512 are hinged through the hinge shaft 53, and the second spring 52 is arranged between the two gripping portions 511 and the two ends of the second spring 52 are connected to the two gripping portions 511. The second spring 52 is always in a compressed state. Under the condition that there is no external force, the elastic force of the second spring 52 pushes the two gripping portions 511 away from each other. Since the two clamping arms 51 are cross-arranged and the hinge point is located between the gripping portion 511 and the clamping portion 513, the two gripping portions 511 move away from each other while the two clamping portions 513 move closer to each other. In this way, without being subjected to external forces, the clamping assembly 5 can further compress the first pipeline 6 or the second pipeline 7, so that the inner wall of the first pipeline 6 or the second pipeline 7 fits tightly with the joint of the water pump 100, thereby achieving sealing. When it is necessary to connect the first pipeline 6 and the second pipeline 7 to the water pump 100, the holding portion 511 of the clamping assembly 5 is pressed, the two holding portions 511 approach each other, the second spring 52 is further compressed, and the two clamping portions 513 move away from each other. After the first pipeline 6 or the second pipeline 7 is sleeved on the joint of the water pump 100, the external force applied to the holding portion 511 is gradually removed, and the two holding portions 511 move away from each other under the elastic force of the second spring 52, while the two clamping portions 513 move closer to each other until the first pipeline 6 or the second pipeline 7 is clamped, so that it fits tightly with the joint of the water pump 100, thereby achieving sealing. The provision of the clamping assembly 5 makes it easier and faster to connect the first pipeline 6 and the second pipeline 7 to the water pump 100, thereby reducing the difficulty of the operation and improving the operation speed.

[0040] Alternatively, if Figure 1-Figure 4 As shown, the water pump stall test fixture also includes a support assembly 8, which is used to support the first pipeline 6 or the second pipeline 7 to prevent the first pipeline 6 and the second pipeline 7 from being deformed or loosened from the connection position of the pipeline under the action of their own gravity. The support assembly 8 includes a support plate 81, a support rod 82 and a support sleeve 83. The support rod 82 is fixedly connected to the bracket 1, the support rod 82 is vertically fixedly connected to the support plate 81, and the support sleeve 83 is fixedly connected to the upper end of the support rod 82. The support sleeve 83 can be sleeved on the first pipeline 6 or the second pipeline 7, thereby supporting the first pipeline 6 or the second pipeline 7.

[0041] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
