Movable base and water pump

Abstract

The application belongs to the technical field of water pumps, and particularly relates to a movable base and a water pump. The movable base comprises a base body, a bolt, a roller assembly and a linkage mechanism connecting the bolt and the roller assembly. When the bolt is tightened, the bolt extends out of a containing groove and is connected with a base surface to fix the base on the base surface. When the bolt is loosened, the bolt is withdrawn into the containing groove and is disconnected with the base surface. During the process of tightening the bolt, the bolt can drive the roller assembly to be withdrawn into the containing groove through the linkage mechanism, so that the roller assembly does not interfere with the connection between the base body and the base surface. During the process of loosening the bolt, the bolt can drive the roller assembly to extend out of the containing groove through the linkage assembly, so that the roller assembly is in contact with the base surface and supports the base body. The base can be moved on the base surface through the roller assembly, so that the water pump can be moved to an open space during maintenance, which saves time and effort.

Description

Technical Field

[0001] This invention relates to the field of water pump technology, and in particular to a movable base and a water pump. Background Technology

[0002] Water pumps, as general industrial products, are used in various industries and are closely related to our lives, such as for daily water use, heating systems, and air conditioning circulating water systems. Existing water pumps typically consist of a pump body and a base. The pump body is fixed to the base with bolts, and the base is fixed to the foundation surface (cement or concrete floor) with bolts.

[0003] Because some water pumps are large and heavy, especially during maintenance, the operating environment often necessitates moving them to an open space. Existing connection methods are inconvenient for pump movement, leading to time-consuming and labor-intensive maintenance. Summary of the Invention

[0004] To address the problem of time-consuming and labor-intensive maintenance caused by the inconvenience of moving water pumps, this invention provides a movable base and a water pump.

[0005] According to an embodiment of the present invention, a first aspect provides a movable base, characterized in that it comprises:

[0006] The base has a receiving groove at its bottom, the opening of which faces the bottom of the base, and a first threaded hole at its top, which communicates with the receiving groove.

[0007] A bolt is inserted into the first threaded hole, and the bottom of the bolt extends out of the bottom of the seat to connect to the base surface;

[0008] A roller assembly is movably disposed in the receiving groove, the roller assembly being able to retract or extend from the receiving groove;

[0009] A linkage mechanism is used to connect the bolt and the roller assembly;

[0010] When the bolt is connected to the base surface, the bolt drives the roller assembly to retract into the receiving groove through the linkage mechanism; when the bolt is disconnected from the base surface, the bolt drives the roller assembly to extend out of the receiving groove through the linkage mechanism.

[0011] In some embodiments, the roller assembly includes a support and a roller, the support being hinged in the receiving groove, the roller being rotatably connected to the support, and the roller retracting or extending from the receiving groove via the support in a swinging manner.

[0012] In some embodiments, the bracket is strip-shaped, with its top hinged to the bottom of the receiving groove and its bottom connected to the roller. When the roller swings in a direction close to the bolt, it extends out of the receiving groove.

[0013] In some embodiments, the linkage mechanism includes a linkage ring platform fixedly mounted on the bolt and a first linkage block and a second linkage block mounted on the bracket; the first linkage block is correspondingly mounted on the top side of the linkage ring platform, and the linkage ring platform is used to abut against the bottom of the first linkage block, so that the roller extends out of the receiving groove; the second linkage block is mounted on the bottom side of the linkage ring platform, and the linkage ring platform is used to abut against the top of the second linkage block, so that the roller retracts into the receiving groove.

[0014] In some embodiments, the outer edge of the linkage ring platform is rounded.

[0015] In some embodiments, the bolt includes a first threaded portion for connecting the seat body and a second threaded portion for connecting the base surface, the first threaded portion and the second threaded portion being separated by the linkage ring platform.

[0016] In some embodiments, the first threaded portion and the second threaded portion are integrally formed, and the nominal diameter of the first threaded portion is larger than the nominal diameter of the second threaded portion.

[0017] In some embodiments, after the second threaded portion passes through the first threaded hole, the linkage ring is fixed between the first threaded portion and the second threaded portion.

[0018] In some embodiments, at least the first threaded portion and the second threaded portion are joined together.

[0019] According to an embodiment of the present invention, a second aspect provides a water pump comprising a pump body and the aforementioned movable base, the pump body being fixed to the movable base.

[0020] In the movable base of this invention, when the bolt is tightened, the bolt extends out of the receiving groove and connects with the base surface to fix the base to the base surface; when the bolt is loosened, the bolt retracts into the receiving groove and disconnects from the base surface. During the tightening process, the bolt can synchronously drive the roller assembly to be housed in the receiving groove through the linkage mechanism, avoiding interference between the roller assembly and the connection between the base body and the base surface; during the loosening process, the bolt can synchronously drive the roller assembly to extend out of the receiving groove through the linkage mechanism, so that the roller assembly contacts the base surface and supports the base body. The base can move on the base surface through the roller assembly, making it convenient for the water pump to be moved to an open space during maintenance, saving time and effort.

[0029] like Figure 1 As shown, this embodiment discloses a water pump, which includes a pump body 50 and a movable base, wherein the pump body 50 is fixed on the movable base, and the movable base is fixedly connected to the base surface 60 (cement or concrete ground).

[0030] See details Figure 2and Figure 3 The movable base of this embodiment includes a base 10, a bolt 20, a roller assembly, and a linkage mechanism connecting the bolt 20 and the roller assembly. A receiving groove 11 is provided at the bottom of the base 10, with the opening of the groove 11 facing the bottom of the base 10 and the bottom of the groove facing the top of the base 10. A first threaded hole is provided at the top of the base 10, communicating with the receiving groove 11. In this embodiment, the bolt 20 passes through the first threaded hole, and the bottom of the bolt 20 can extend out of the bottom of the base 10 through the first threaded hole and the receiving groove 11. The portion of the bolt 20 extending out of the base connects to a second threaded hole 61 on the base surface 60, thereby fixing the base 10 to the base surface 60.

[0031] In this embodiment, the roller assembly is movably disposed in the receiving groove 11, and the roller assembly can retract or extend from the receiving groove 11. In this embodiment, the bolt 20 is connected to the roller assembly through a linkage mechanism. When the bolt 20 extends out of the receiving groove 11 and connects with the base surface 60, the bolt 20 drives the roller assembly to retract into the receiving groove 11. When the bolt 20 retracts into the receiving groove 11 and disconnects from the base surface 60, the bolt 20 drives the roller assembly to extend out of the receiving groove 11.

[0032] In the movable base of this embodiment, when the bolt 20 is tightened, the bolt 20 extends out of the receiving groove 11 and connects with the base surface 60 to fix the base on the base surface 60; when the bolt 20 is loosened, the bolt 20 retracts into the receiving groove 11 and disconnects from the base surface 60. During the tightening process of the bolt 20, the bolt 20 can synchronously drive the roller assembly to be housed in the receiving groove 11 through the linkage mechanism, avoiding interference between the roller assembly and the connection between the base body 10 and the base surface 60; during the loosening process of the bolt 20, the bolt 20 can synchronously drive the roller assembly to extend out of the receiving groove 11 through the linkage mechanism, so that the roller assembly contacts the base surface 60 and supports the base body 10. The base can move on the base surface 60 through the roller assembly, which facilitates the movement of the water pump to an open space during maintenance, saving time and effort.

[0033] The roller assembly of this embodiment preferably includes a bracket 30 and a roller 31. The bracket 30 is hinged in the receiving groove 11, and the roller 31 is rotatably mounted on the bracket 30. The bracket 30 and the roller assembly can swing around the hinge position. The roller 31 retracts or extends from the receiving groove 11 by swinging through the bracket 30. Its structure is simple and easy to install. Specifically, the bracket 30 of this embodiment is preferably strip-shaped. The top of the bracket 30 is hinged to the bottom of the receiving groove 11, and the bottom of the bracket 30 is connected to the roller 31. When the roller 31 swings in the direction close to the bolt 20, the angle between the bracket 30 and the bolt 20 decreases, and the roller 31 can extend out of the receiving groove 11. At this time, the bracket 30 gradually becomes parallel to the bolt 20. The longitudinal direction of the bracket 30 is approximately vertical, which can approximately coincide with the direction of gravity of the seat 10, which helps the roller assembly to support the seat 10. It should be noted that the roller assembly of this embodiment can also retract or extend from the receiving groove 11 in a conventional manner such as sliding or telescopic as needed.

[0034] The linkage mechanism of this embodiment includes a linkage ring platform 40 fixedly mounted on the bolt 20 and a first linkage block 41 and a second linkage block 42 mounted on the bracket 30. The first linkage block 41 is correspondingly mounted on the top side of the linkage ring platform 40. When the linkage ring platform 40 retracts into the receiving groove 11 along with the bolt 20, the linkage ring platform 40 abuts against the bottom of the first linkage block 41, thereby causing the roller 31 in the rolling assembly to extend out of the receiving groove 11. The second linkage block 42 is mounted on the bottom side of the linkage ring platform 40. When the linkage ring platform 40 retracts into the receiving groove 11 along with the bolt 20, the linkage ring platform 40 abuts against the top of the second linkage block 42, thereby causing the roller 31 in the rolling assembly to retract into the receiving groove 11. In other words, when the water pump is working normally, the bolt 20 needs to be screwed into the base surface 60. The bolt 20, through the linkage ring platform 40 and the second linkage block 42, drives the bracket 30 and the roller assembly to swing towards the inside of the receiving groove 11. At this time, there is a gap between the roller assembly and the base surface 60 to prevent the roller assembly from affecting the fixation of the base and the base surface 60. When the water pump is being repaired, the bolt 20 needs to be screwed out of the base surface 60. The bolt 20, through the linkage ring platform 40 and the first linkage block 41, drives the bracket 30 and the roller assembly to swing towards the inside of the receiving groove 11. At this time, the roller assembly contacts the base surface 60 to facilitate the movement of the base. It should be noted that the linkage mechanism of this embodiment can also select conventional structures such as connecting rods and gear sets to make the bolt 20 drive the roller assembly to move as needed.

[0035] See details Figure 4 In this embodiment, the bolt 20 preferably includes a first threaded portion 21 for connecting to a threaded hole and a second threaded portion 22 for connecting to a base surface 60. The first threaded portion 21 and the second threaded portion 22 are separated by a linkage ring platform 40. The bolt 20 has two threaded sections that are respectively screwed into the threaded holes on the seat 10 and the base surface 60, which can avoid interference during assembly.

[0036] In some embodiments, the first threaded portion 21 and the second threaded portion 22 may be integrally formed as required. The nominal diameter of the first threaded portion 21 is preferably larger than the nominal diameter of the second threaded portion 22, so that the second threaded portion 22 can be screwed into the second threaded hole 61 after passing through the first threaded hole. After the second threaded portion 22 passes through the first threaded hole, the linkage ring 40 is fixed between the first threaded portion 21 and the second threaded portion 22, so that the bolt 20 can be connected to the linkage mechanism.

[0037] In some embodiments, at least the first threaded portion 21 and the second threaded portion 22 can be spliced ​​together as required. The linkage ring 40 can be integrally formed with the second threaded portion 22 as required. In this case, the first threaded portion 21 needs to be passed through the first threaded hole first, and then the first threaded portion 21 and the second threaded portion 22 need to be spliced ​​together. Alternatively, the linkage ring 40 can be spliced ​​separately between the first threaded portion 21 and the second threaded portion 22.

[0038] In this embodiment, the outer edge of the linkage ring platform 40 is preferably rounded, so that the linkage ring platform 40 abuts against the first linkage block 41 and the second linkage block 42 through a smooth surface, which helps to reduce wear at the contact point and extend the service life. In this embodiment, a groove 62 is provided on the base surface 60 to guide the roller 31. The groove 62 can guide the roller 31 to roll into an open space to facilitate the maintenance of the water pump.

[0039] 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.

[0040] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
