[0002] Water pumps are machines used to transport or pressurize liquids, and are widely used in various industries and daily life. Currently, water pumps are typically assembled with one set of support legs per pump. However, different pump motors of varying specifications have different heights, so a single pump needs multiple sets of support legs to accommodate different motor heights, resulting in material waste. Utility Model Content

[0003] Based on this, the present invention provides an adjustable support device and a water pump system to solve the problem that the support height of the existing support device is fixed and cannot match the support of equipment of different specifications, resulting in poor versatility.

[0004] A single water pump requires multiple support devices to accommodate the height of pump motors of different specifications, leading to material waste.

[0005] This utility model provides an adjustable support device, characterized in that it includes a support foot and an adjustment component, wherein the support foot is provided with a screw hole;

[0006] The adjustment component includes:

[0007] An adjusting stud is screwed into the screw hole of the support foot, and the upper end of the adjusting stud is used to connect to the object to be supported;

[0008] The movable clip has one end connected to the support leg and the other end being a free end, with the free end of the movable clip located relative to the outer periphery of the adjusting stud.

[0009] A locking fastener, detachably mounted on the support foot, is used to drive the free end of the movable clip to move toward the adjusting stud, so that the free end of the movable clip is locked onto the outer circumferential thread of the adjusting stud.

[0010] In one embodiment, the support foot is made of a vibration-absorbing material.

[0011] In one embodiment, a metal sleeve is mounted on the support foot, and the screw hole is located inside the metal sleeve.

[0012] In one embodiment, the support foot is provided with a groove, the movable clip is disposed in the groove, and a slot is formed between the movable clip and the side of the groove away from the adjusting stud;

[0013] The locking device is a wedge that can be inserted into the slot and move the movable card toward the adjusting stud;

[0014] The side of the metal sleeve is provided with a clearance notch, which is opposite to and communicates with the groove, so that when the movable card moves toward the adjusting stud, it can pass through the clearance notch and abut against the adjusting stud.

[0015] In one embodiment, the longitudinal section of the wedge is triangular, the longitudinal section of the slot is also triangular, and in the initial state, the included angle between the two sides of the wedge is greater than the included angle between the two walls of the slot.

[0016] In one embodiment, a limiting structure is provided between the movable card and the wedge. The limiting structure includes a limiting groove disposed on the side of the movable card facing the wedge and a limiting protrusion disposed on the side of the wedge facing the movable card. The shapes of the limiting protrusion and the limiting groove are adapted to each other.

[0017] In one embodiment, there are two movable cards, which are disposed opposite to each other on the upper end of the metal sleeve, and both movable cards are arc-shaped.

[0018] The locking device includes a locking ring, which is sleeved on the two movable clips. The inner hole of the locking ring is provided with two arc-shaped guide walls. The distance between the first end and the second end of each arc-shaped guide wall and the center of the locking ring gradually decreases along the first rotation direction.

[0019] The two movable clips are respectively attached to the two arc-shaped guide walls, and when the movable clip is located at the first end of the arc-shaped guide wall, the diameter of the inner wall surface of the movable clip is greater than or equal to the diameter of the adjusting stud.

[0020] In one embodiment, the inner sides of both movable cards are provided with threaded structures that engage with the internal threads of the screw holes.

[0021] In one embodiment, the upper end of the support leg is provided with a support surface for placing the locking ring;

[0022] Each of the movable cards has an arc-shaped pressing edge at its upper end. The pressing edge protrudes outward from the movable card, and the distance between the bottom surface of the pressing edge and the support surface is equal to or slightly greater than the thickness of the locking ring.

[0023] Furthermore, the diameter of the circle containing the two pressing edges is less than or equal to the diameter of the circle containing the arcuate segments of the two arcuate guide walls near their first ends, and greater than the diameter of the circle containing the arcuate segments of the two arcuate guide walls near their second ends.

[0024] On the other hand, the present invention also provides a water pump system, which includes a water pump and a water pump motor connected to each other, and the water pump motor is supported below an adjustable support device as described in any of the above embodiments.

[0025] Compared with the prior art, this utility model has at least the following beneficial effects:

[0026] The aforementioned adjustable support device connects the upper end of an adjusting stud to the object to be supported and the lower end to the threaded hole of a support foot. Rotating the support foot moves it along the adjusting stud, thus adjusting the distance (support height) between the support foot and the object. This allows for matching different support heights with a single device, enhancing versatility and effectively reducing material costs. A movable catch on the support foot enables the free end of the catch to move towards the adjusting stud after height adjustment, until it locks into the outer thread of the adjusting stud. This locks the support foot and adjusting stud, preventing loosening due to vibration and ensuring the stability of the device. Attached Figure Description

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] Existing water pumps are usually assembled with one set of support legs for each pump. However, different pump motors of different specifications have different heights, so one pump needs to be equipped with multiple sets of support legs to accommodate different pump motor heights, which results in a waste of materials.

[0043] In response to this, this utility model provides an adjustable support device that can match different support heights, making it more versatile, effectively saving materials and reducing costs.

[0044] The adjustable support device provided in this embodiment of the utility model includes a support foot 1 and an adjustment component 2, wherein the support foot 1 is provided with a screw hole 101;

[0045] Adjustment component 2 includes:

[0046] Adjusting stud 201 is screwed into the screw hole 101 of the support foot 1, and the upper end of adjusting stud 201 is used to connect the object to be supported;

[0047] The movable clip 202 has one end connected to the support leg 1 and the other end is a free end, and the free end of the movable clip 202 is located on the outer periphery of the adjusting stud 201.

[0048] The locking fastener 203 is detachably mounted on the support foot 1 and is used to drive the free end of the movable clip 202 to move toward the adjusting stud 201 so that the free end of the movable clip 202 is locked onto the outer circumferential thread of the adjusting stud 201.

[0049] According to the adjustable support device of this utility model embodiment, by connecting the upper end of the adjusting stud 201 to the object to be supported and screwing the lower end to the screw hole 101 of the support foot 1, rotating the support foot 1 allows it to move along the adjusting stud 201, thereby adjusting the distance (support height) between the support foot 1 and the object to be supported. This achieves the purpose of matching different support heights with a single support device, making it more versatile and effectively reducing material costs. By setting a movable clip 202 on the support foot 1, after the support height adjustment is completed, the free end of the movable clip 202 can be driven by the locking fastener 203 to move closer to the adjusting stud 201 until the free end of the movable clip 202 is locked onto the outer thread of the adjusting stud 201. This achieves locking between the support foot 1 and the adjusting stud 201, preventing loosening between the support foot 1 and the adjusting stud 201 due to vibration or other reasons, and ensuring the support stability of the device.

[0050] It should be noted that the adjustable support device of this embodiment can be applied to different environments where the support height needs to be adjusted. Accordingly, the object to be supported mentioned in this embodiment can be any equipment component. For example, corresponding to a water pump system, this adjustable support device can be used to stably support water pump motors of different specifications, and the object to be supported is the water pump motor. The following section will also use the water pump motor as an example to illustrate the object to be supported.

[0051] The adjustable support device and water pump system provided in the embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0052] according to Figure 9An exemplary water pump system according to at least one embodiment of the present invention is shown. The water pump system includes a water pump 100 and a water pump motor 200 connected to each other, and an adjustable support device 300 is supported below the water pump motor 200.

[0053] according to Figure 1 An adjustable support device 300 according to at least one embodiment of the present invention is shown as an example. The adjustable support device 300 includes: a support foot 1 and an adjustment component 2.

[0054] Among them, the support foot 1 is the main component of this adjustable support device 300, which is usually in contact with the ground or workbench surface, and is used to support the weight of the water pump motor 200 and maintain stability.

[0055] In this embodiment, the support leg 1 can be of any suitable shape, as long as it can ensure that the support leg 1 can provide horizontal support for the water pump motor. For example, see... Figure 1 and Figure 4 In this embodiment, the support foot 1 is frustum-shaped and the bottom surface of the support foot 1 is a horizontal support surface. In this way, the support foot 1 can be stably and horizontally supported on the ground or workbench, ensuring the overall stability of the adjustable support device.

[0056] Furthermore, in this embodiment, the support foot 1 is made of vibration-absorbing material. Since the water pump motor continuously vibrates during operation, it can cause adverse effects such as low motor efficiency and high noise. Therefore, to reduce or eliminate the adverse effects of vibration, the support foot 1 in this embodiment uses vibration-absorbing material, enabling it to absorb the vibration of the water pump motor during operation, reducing vibration and noise, protecting the water pump motor 200 and its related equipment, and extending its service life. Specifically, the support foot 1 can be made of materials such as rubber or plastic.

[0057] In this embodiment, the adjusting component 2 is used to adjust the support height of the support device to match the support height of water pump motors of different specifications. Specifically, see... Figure 1 and Figure 2 The adjustment component 2 includes an adjustment stud 201, a movable clip 202, and a locking fastener 203.

[0058] In this embodiment, the adjusting stud 201 is used to connect the water pump motor and the support foot 1, and to adjust the distance between the water pump motor 200 and the support foot 1, so as to adjust the support height of the entire support device.

[0059] Specifically, in this embodiment, the adjusting stud 201 is a self-tapping stud, with its upper end being a self-tapping end, which can be screwed onto the housing of the water pump motor 200. The lower end of the adjusting stud 201 is threadedly connected to the support leg 1. For more details, see... Figure 1The support leg 1 is provided with a screw hole 101, and the lower end of the adjusting stud 201 is screwed into the screw hole 101 of the support leg 1. This design, using a self-tapping stud, allows the upper end of the adjusting stud 201 to be screwed tightly onto water pump motors 200 of different specifications, offering strong adaptability and simple, convenient operation. Furthermore, by controlling the depth to which the adjusting stud 201 is screwed into the screw hole 101 of the support leg 1, the distance between the support leg 1 and the water pump motor 200 can be adjusted, thereby achieving adjustment of the support height of the support device. This adjustment is convenient and quick.

[0060] Further, see Figure 1 A metal sleeve 3 is installed inside the support foot 1. The screw hole 101 of the support foot 1 is set inside the metal sleeve 3. The metal sleeve 3 can be made of stainless steel. With this setting, the threaded structure of the metal material can enhance the connection strength between the adjusting stud 201 and the support foot 1. Moreover, it has better wear resistance and stronger load-bearing capacity, which is conducive to achieving stable support for the water pump motor 200.

[0061] Furthermore, in this embodiment, the metal sleeve 3 is integrally fixed to the middle of the support foot 1. For example, the support foot 1 is wrapped around the outer periphery of the metal sleeve 3 by injection molding, thereby achieving integral fixation between the metal sleeve 3 and the support foot 1.

[0062] In this embodiment, the movable card 202 and the locking fastener 203 are both disposed on the support foot 1, and are used to lock the adjusting stud 201 to the support foot 1 after the support height adjustment is completed, so as to ensure the support stability of the water pump motor.

[0063] For details, see Figure 1 , Figure 2 and Figure 4 In this embodiment, the movable clip 202 is a sheet-like structure located on the outer periphery of the adjusting stud 201. One end of the movable clip 202 is connected to the support foot 1, and the other end is a free end. The free end of the movable clip 202 can swing around the connection point between the movable clip 202 and the support foot 1, so that the movable clip 202 can move towards or away from the adjusting stud 201. During the process of the movable clip 202 moving towards the adjusting stud 201, the movable clip 202 abuts against the adjusting stud 201, thereby locking the adjusting stud 201 and preventing the adjusting stud 201 from rising, falling, or rotating, thus ensuring the positioning stability of the adjusting stud 201.

[0064] See Figure 2In a specific example, the top of the support foot 1 is provided with a groove, which is located on the outer periphery of the metal sleeve 3. The movable clip 202 is disposed in the groove. Correspondingly, the side of the metal sleeve 3 is provided with a clearance notch 205, which is horizontally opposite to and connected to the groove, so that part of the external thread on the adjusting stud 201 inside the metal sleeve 3 is exposed. In this way, by driving the movable clip 202 to move closer to the adjusting stud 201 through the locking fastener 203, the movable clip 202 can pass through the clearance notch 205 of the metal sleeve 3 and abut against and lock with the external thread of the adjusting stud 201, thereby achieving the limiting of the adjusting stud 201.

[0065] For details, see Figure 2 The activity card 202 is a card whose lower end is connected to the bottom of the groove. For example, the lower end of the activity card 202 is integrally injection molded with the bottom of the groove, while the upper end of the activity card 202 is a free end, extending upward to the top opening of the groove. See also Figure 2 A slot 204 is formed between the movable clip 202 and the side of the groove away from the adjusting stud 201. The locking fastener 203 is a wedge that can be inserted into the slot 204 and move the movable clip 202 toward the adjusting stud 201. With this configuration, when it is necessary to lock the adjusting stud 201, inserting the wedge into the slot 204 will drive the free end of the movable clip 202 through the clearance notch 205 and abut against the external thread of the adjusting stud 201 to lock it in place.

[0066] More specifically, the wedge can be shaped like a cone that is wider at the top and narrower at the bottom, for example, Figure 2 An embodiment is shown where the wedge has a triangular longitudinal section, and the slot 204 is adapted to the shape of the wedge; for example, corresponding to the triangular wedge, the longitudinal section of the slot 204 is also triangular. Furthermore, as... Figure 2 As shown, in the initial state, i.e., when the wedge is not inserted into the slot 204, the included angle between the two sides of the wedge is greater than the included angle between the two inner walls of the slot 204. This allows the wedge to press the movable clip 202 towards the adjusting stud 201 during the insertion process into the slot 204. Figure 3 As shown, when the wedge is fully inserted into the slot 204, the movable card 202 abuts against the adjusting stud 201.

[0067] Further, see Figure 2 A limiting structure is provided between the movable card 202 and the wedge. The limiting structure includes a limiting groove 206 on the side of the movable card 202 facing the wedge and a limiting protrusion 207 on the side of the wedge facing the movable card 202. The limiting protrusion 207 and the limiting groove 206 are shaped to match; for example, both the limiting protrusion 207 and the limiting groove 206 are triangular. With this configuration, during the insertion of the wedge into the slot 204, as... Figure 3As shown, when the limiting protrusion 207 of the wedge is engaged in the limiting groove 206, the wedge can be limited in the slot 204, ensuring the squeezing stability of the wedge against the movable card 202, thereby improving the positioning stability of the adjusting stud 201.

[0068] See Figure 4 In another embodiment, two movable clips 202 are provided. Both movable clips 202 are arc-shaped and are positioned opposite each other on the upper end of the metal sleeve 3, with both movable clips 202 located above the support foot 1. In the initial state, both movable clips 202 are located outside the adjusting stud 201 to ensure that the two movable clips 202 do not interfere with the relative rotation between the adjusting stud 201 and the support foot 1 in the initial state.

[0069] See Figure 4 and Figure 5 The locking device 203 includes a locking ring, which can be sleeved on two movable clips 202. Two arc-shaped guide walls 2031 are provided in the inner hole of the locking ring, and the distance between the first end and the second end of each arc-shaped guide wall 2031 and the center of the locking ring gradually decreases along a first rotation direction. The first rotation direction is... Figure 5 The direction shown is counterclockwise. See also Figure 5 Two movable clips 202 are located within two arc-shaped guide walls 2031. When the movable clip 202 is located at the first end of the arc-shaped guide wall 2031, the arc-shaped guide wall 2031 does not compress the movable clip 202. At this time, the diameter of the inner wall surface of the movable clip 202 is greater than or equal to the diameter of the adjusting stud 201. When the movable clip 202 is located at the second end of the arc-shaped guide wall 2031, the diameter of the inner wall surface of the movable clip 202 is smaller than the diameter of the adjusting stud 201. With this setting, in the initial state, see... Figure 5 The two movable clips 202 are located at the first ends of the two arc-shaped guide walls 2031, respectively. At this time, the two movable clips 202 are not locked to the adjusting stud 201, and the support height of the support device can be freely adjusted. When it is necessary to lock the adjusting stud 201, rotate the locking ring in the first rotation direction (counterclockwise direction), see [reference]. Figure 6 The arc-shaped guide wall 2031 of the locking ring will apply an inward squeezing force to the movable clip 202, causing the movable clip 202 to move towards the adjusting stud 201 until the two movable clips 202 completely clamp the adjusting stud 201. At this time, the relative fixation of the support foot 1 and the adjusting stud 201 can be achieved.

[0070] Further, see Figure 4 The upper end of the support foot 1 is provided with a support surface 102 for placing the locking ring, so as to facilitate the stable placement of the locking ring.

[0071] Further, see Figure 4In this embodiment, each movable card 202 has an arc-shaped pressing edge 2021 at its upper end. The pressing edge 2021 protrudes outward from the movable card, and the distance between the bottom surface of the pressing edge 2021 and the support surface 102 is equal to or slightly greater than the thickness of the locking ring.

[0072] See Figure 7 The diameter of the circle containing the two pressure edges 2021 is less than or equal to the diameter of the circle containing the arc-shaped segments of the two arc-shaped guide walls 2031 near their first ends, and greater than the diameter of the circle containing the arc-shaped segments of the two arc-shaped guide walls 2031 near their second ends. This allows the inner hole of the locking ring to pass downwards through the two pressure edges 2021 and be fitted onto the two movable clips 202 when the arc-shaped segments of the two arc-shaped guide walls 2031 near their first ends are aligned with the two pressure edges 2021. See also Figure 8 After the locking ring is rotated counterclockwise, it will be embedded inside the pressure edge 2021. At this time, the locking ring can be limited by the pressure edge 2021 to lock the locking ring and ensure the positioning stability of the adjusting stud 201.

[0073] Furthermore, see Figure 4 Both movable clips 202 have threaded structures on their inner sides, and the threaded structures of the movable clips 202 are connected to the internal threads of the screw holes 101 of the metal sleeve 3. This arrangement allows the movable clips 202 and the adjusting stud 201 to also be threaded together. When the two movable clips 202 clamp the adjusting stud 201, the mating threads between the movable clips 202 and the adjusting stud 201 can be used for limiting the position, ensuring the positioning stability of the adjusting stud 201.

[0074] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The above embodiments merely illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
