Description

Technical Field

[0001] This utility model relates to the field of water pump technology, and in particular to a circulating water pump. Background Technology

[0002] A circulating water pump is a device used to transport liquids (such as water, coolant, chemical solutions, etc.), and is widely used in HVAC systems, industrial cooling systems, hot water circulation systems, and agricultural irrigation systems. Its main function is to use mechanical energy to transport liquids from low-pressure areas to high-pressure areas and to achieve the circulation of the liquid.

[0003] In existing technology, workers usually connect pipes to inlet flanges by hand. However, holding pipes for a long time can put pressure on the workers' hand muscles and cause their hands to shake, which in turn causes the pipes to shake, thus affecting the installation efficiency of the pipes and inlet flanges and reducing the workers' installation efficiency. Utility Model Content

[0004] This utility model mainly provides a circulating water pump.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a circulating water pump, including a mounting base, a motor mounted on the mounting base, a water pump mounted on the mounting base to the left of the motor, an inlet on the left side of the water pump, an outlet on the top of the water pump, a pipe connected to the left side of the inlet via a flange, a limiting component on the left side of the water pump, the water pump limiting the pipe via the limiting component, and a storage component at the front end of the mounting base.

[0006] Preferably, the limiting component includes two sets of movable chambers disposed on the outer wall of the water pump at the upper and lower ends of the inlet. Each movable chamber has a guide rod on its inner wall, a spring wound around each guide rod, and a slider sliding on each guide rod. One end of each slider is fixedly connected to the other end of the spring. Each slider has a socket on its surface facing the inlet. Each slider has a positioning post inside the pipe, which is slidably connected to the socket. A positioning groove is opened on the outer wall of the inlet corresponding to the right end of each positioning post. Each set of sliders has a handle at its front end.

[0007] Preferably, the handle is cylindrical in shape, and the surface of the handle has anti-slip texture.

[0008] Preferably, one end of the spring is welded to the surface of the slider, and the other end of the spring is welded to the inner wall of the movable chamber.

[0009] Preferably, the storage component includes a storage box disposed on the front surface of the mounting base. The storage box has two sets of fixing blocks on its left side, and a cover plate is rotatably disposed inside the fixing blocks. The storage box has a fixing seat on its right side, and a rotating rod is rotatably disposed inside the fixing seat. A torsion spring is wound around the rotating rod, and a limiting plate is disposed at the top of the rotating rod.

[0010] Preferably, the limiting plate is rectangular in shape, and an anti-slip pad is provided on the side of the limiting plate facing the cover plate.

[0011] Preferably, both the storage box and the cover are designed to be transparent.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the positioning pin is inserted into the positioning groove by the pipe, and then the restoring force of the spring drives the slider to slide back on the guide rod. The slider also drives the positioning pin and the pipe to slide back through the socket, so that the pipe and the water inlet are tightly fitted. This achieves the purpose of positioning the internal threaded hole of the pipe and the water inlet, so that the workers can make flange connections between the pipe and the water inlet. This reduces the occurrence of installation errors between the pipe and the water inlet and further improves the efficiency of connecting the pipe and the water inlet.

[0014] 2. In this utility model, by rotating the cover plate inside the fixed block, the cover plate is turned off from the storage box, and the fasteners inside the storage box are taken out. When the fasteners are not in use, they are stored in the storage box. Then, the cover plate is rotated to the top of the storage box. Then, the restoring force of the torsion spring drives the rotating rod to reset and rotate in the fixed seat, and the rotating rod synchronously drives the limiting plate to fix the cover plate. This allows the staff to take out or store the fasteners at any time when using the bolts, preventing the fasteners from being lost or missing. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a circulating water pump, including a mounting base 1, a motor 2 mounted on the mounting base 1, a water pump 3 mounted on the mounting base 1 to the left of the motor 2, a water inlet 4 on the left side of the water pump 3, a water outlet 5 on the top of the water pump 3, a pipe 6 connected to the left side of the water inlet 4 via a flange, a limiting component 7 on the left side of the water pump 3, the water pump 3 limiting the pipe 6 via the limiting component 7, and a storage component 8 at the front end of the mounting base 1.

[0023] like Figure 2 and 3 As shown, the limiting component 7 includes two sets of movable chambers 71 set on the outer wall of the water pump 3 at the upper and lower ends of the inlet 4. Each movable chamber 71 has a guide rod 72 on its inner wall, and a spring 73 is wound around each guide rod 72. Each guide rod 72 has a slider 74 sliding on it. One end of the slider 74 is fixedly connected to the other end of the spring 73. Each slider 74 has a socket 75 on its side facing the inlet 4. Each pipe 6 has a positioning post 76, which is slidably connected to the socket 75. The right end of the positioning post 76 has a positioning groove 77 on the outer wall of the inlet 4. Each set of sliders 74 has a handle 78 at its front end.

[0024] The positioning pin 76 is inserted into the positioning groove 77 by the pipe 6, and then the restoring force of the spring 73 drives the slider 74 to slide back on the guide rod 72. The slider 74 drives the positioning pin 76 and the pipe 6 to slide back through the socket 75, so that the pipe 6 and the water inlet 4 are tightly fitted. This achieves the purpose of positioning the internal threaded hole of the pipe 6 and the water inlet 4, so that the staff can make flange connection between the pipe 6 and the water inlet 4. This reduces the possibility of installation errors between the pipe 6 and the water inlet 4 and further improves the efficiency of connecting the pipe 6 and the water inlet 4.

[0025] like Figure 2 As shown, the handle 78 has a cylindrical design and the surface of the handle 78 is provided with anti-slip texture, which can increase the friction between the operator's hand and the handle 78, and at the same time increase the contact area between the handle 78 and the operator's hand, thereby improving the stability of the handle 78 during use.

[0026] like Figure 3 As shown, one end of the spring 73 is welded to the surface of the slider 74, and the other end of the spring 73 is welded to the inner wall of the movable chamber 71. This can fix both ends of the spring 73 to prevent the vibration generated when the mounting base 1 or the water pump 3 is working from causing the spring 73 to swing back and forth on the guide rod 72 and hit the movable chamber 71 or the slider 74, thus preventing noise pollution.

[0027] like Figure 4 As shown, the storage component 8 includes a storage box 81 disposed on the front surface of the mounting base 1. Two sets of fixing blocks 82 are provided on the left side of the storage box 81. A cover plate 83 is rotatably disposed inside the fixing blocks 82. A fixing seat 84 is provided on the right side of the storage box 81. A rotating rod 85 is rotatably disposed inside the fixing seat 84. A torsion spring 86 is wound around the rotating rod 85. A limiting plate 87 is provided at the top of the rotating rod 85.

[0028] By rotating the cover plate 83 within the fixing block 82, the cover plate 83 is rotated off the storage box 81, and the fasteners inside the storage box 81 are removed. When the fasteners are not in use, they are stored in the storage box 81. Then, the cover plate 83 is rotated to the top of the storage box 81. Next, the restoring force of the torsion spring 86 drives the rotating rod 85 to reset and rotate within the fixing seat 84, and the rotating rod 85 synchronously drives the limiting plate 87 to fix the cover plate 83. This allows the staff to easily take out or store the fasteners when they are in use, preventing the fasteners from being lost or missing.

[0029] like Figure 4 As shown, the limiting plate 87 is rectangular in shape. The side surface of the limiting plate 87 facing the cover plate 83 is provided with an anti-slip pad, which makes it easy for the operator to rotate the rotating rod 85 through the limiting plate 87. At the same time, it can also prevent the limiting plate 87 from rotating and rubbing against the surface of the cover plate 83, which may cause damage to the surface of the cover plate 83.

[0030] like Figure 4 As shown, both the storage box 81 and the cover 83 are designed to be transparent, which allows staff to easily understand and observe the internal contents of the storage box 81 from the outside when the cover 83 and the storage box 81 are closed.

[0031] The usage and working principle of this device are as follows: First, push the handle 78 to cause the two sets of sliders 74 to slide on the guide rod 72, stretching the spring 73. Then, align the pipe 6 with the inlet 4, causing the pipe 6 to insert the positioning pin 76 into the positioning groove 77. Next, release the handle 78. The restoring force of the spring 73 causes the sliders 74 to slide back on the guide rod 72, and the sliders 74, through the socket 75, simultaneously cause the positioning pin 76 to slide back to its original position with the pipe 6, ensuring a tight fit between the pipe 6 and the inlet 4. This achieves the purpose of positioning the internal threaded hole of the pipe 6 and the inlet 4.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
