Description

Technical Field

[0001] This utility model belongs to the field of water meter repair and replacement technology, specifically a tool for replacing water meters of various sizes. Background Technology

[0002] Water meters are installed in both private residences and public buildings; these meters operate year-round to measure water consumption. Due to the large number of water meters in use, problems frequently arise requiring replacement. However, when replacing water meters, rust can prevent their removal, making on-site operations difficult. Furthermore, the different sizes of water meters necessitate the use of various tools, increasing repair and replacement costs and wasting valuable time. Utility Model Content

[0003] In view of the above-mentioned problems with existing water meter replacement methods, the purpose of this utility model is to provide a tool for replacing water meters of various sizes.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] This utility model includes a handle, a fixed rod, and a telescopic rod. The handle is provided with a fixed rod, one end of which has a through hole. The telescopic rod is in the shape of an inverted "L". The horizontal side of the "L" and the other end of the fixed rod are both clamping ends, located on the front and rear sides of the water meter to be replaced, respectively. The vertical side of the "L" passes through the through hole and can move relative to the fixed rod, thereby adjusting the distance between the other end of the fixed rod and the horizontal side of the "L". When it moves to the position of the water meter of the corresponding size, it remains fixed with the fixed rod, and the water meter to be replaced is clamped by the horizontal side of the "L" and the other end of the fixed rod.

[0006] Wherein: the end of the vertical side of the "L" shape that passes through the through hole is provided with a threaded section, the through hole is a smooth hole, the length of the threaded section is greater than the thickness of the fixed rod, and nuts are threadedly connected to the threaded sections on the upper and lower sides of one end of the fixed rod. When the telescopic rod moves relative to the fixed rod to the position of the water meter of the corresponding size, the nuts on the upper and lower sides that are threadedly connected to the threaded sections clamp one end of the fixed rod, so that the telescopic rod and the fixed rod are kept fixed.

[0007] The through hole is a light hole, and one end of the fixed rod has a socket A that communicates with the through hole along the radial direction; the end of the "L"-shaped vertical side that passes through the through hole has a socket B that corresponds to different sizes of water meters along the length direction. When the telescopic rod moves relative to the fixed rod to the position of the water meter of the corresponding size, the plug is inserted into the socket A and the corresponding socket B to keep the telescopic rod and the fixed rod fixed.

[0008] The length of the fixed rod is greater than the length of the horizontal side of the "L"-shaped telescopic rod.

[0009] The vertical distance between the other end face of the fixed rod and the center line of the handle's length direction is greater than the vertical distance between the horizontal end face of the "L"-shaped telescopic rod and the center line of the handle's length direction.

[0010] The fixing rod and the handle are integrally formed, or the fixing rod is welded to one end of the handle, and the other end of the handle is the hand-held end.

[0011] The advantages and positive effects of this utility model are as follows:

[0012] 1. The telescopic rod of this utility model can move relative to the fixed rod, thereby adjusting the distance between the telescopic rod and the fixed rod to accommodate water meters of different sizes to be replaced, improving the meter replacement efficiency and saving the tools and time required for water meter replacement.

[0013] 2. This utility model is easy to operate and portable. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Example 1

[0026] like Figures 1 to 3 As shown, the tool in this embodiment includes a handle 1, a fixing rod 2, and a telescopic rod 3. The handle 1 is provided with a fixing rod 2, and one end of the fixing rod 2 has a through hole 5. The telescopic rod 3 is in the shape of an inverted "L". The horizontal side of the "L" and the other end of the fixing rod 2 are both clamping ends, located on the front and rear sides of the water meter 10 to be replaced, respectively. The vertical side of the "L" passes through the through hole 5 and can move relative to the fixing rod 2, thereby adjusting the distance between the other end of the fixing rod 2 and the horizontal side of the "L". When it moves to the position of the water meter 10 of the corresponding size, it remains fixed with the fixing rod 2, and the water meter 10 to be replaced is clamped by the horizontal side of the "L" and the other end of the fixing rod 2.

[0027] In this embodiment, the vertical side of the "L" shape passes through the end of the through hole 5 and is provided with a threaded section 6. The through hole 5 is a smooth hole, and the length of the threaded section 6 is greater than the thickness of the fixing rod 2. Nuts 4 are threadedly connected to the threaded sections 6 on both the upper and lower sides of one end of the fixing rod 2.

[0028] In this embodiment, both the fixed rod 2 and the telescopic rod 3 are cylindrical. The length of the fixed rod 2 is greater than the length of the horizontal side of the "L"-shaped telescopic rod 3. The perpendicular distance between the other end face of the fixed rod 2 and the center line of the handle 1 along its length is greater than the perpendicular distance between the end face of the horizontal side of the "L"-shaped telescopic rod 3 and the center line of the handle 1 along its length.

[0029] The fixing rod 2 and the handle 1 are integrally formed, or the fixing rod 2 is welded to one end of the handle 1, and the other end of the handle 1 is the hand-held end. In this embodiment, the fixing rod 2 is welded to one end of the handle 1, and the handle 1, the fixing rod 2, and the telescopic rod 3 are all made of stainless steel.

[0030] This embodiment is applicable to water meters 10 with diameters of φ20, φ25, and φ40. For example... Figure 4 As shown, when replacing water meter 10, hold handle 1 with one hand and place the fixed rod 2 and telescopic rod 3 on the front and rear sides of water meter 10. Then adjust the distance between telescopic rod 3 and fixed rod 2. When telescopic rod 3 moves to the position of water meter 10 of the corresponding size relative to fixed rod 2, clamp one end of fixed rod 2 by the nuts 4 on the upper and lower sides that are threaded to threaded section 6, so that telescopic rod 3 and fixed rod 2 are fixed. Finally, use a wrench with the other hand to turn the connector connected to water meter 10, which greatly improves the efficiency of meter replacement.

[0031] Example 2

[0032] like Figures 5 to 8 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the through hole 5 at one end of the fixing rod 2 is a smooth hole, and the end of the fixing rod 2 has a radially arranged insertion hole A7 communicating with the through hole 5. The end of the "L"-shaped vertical side passing through the through hole 5 does not have a threaded section 6, but instead has insertion holes B8 along its length corresponding to different sizes of water meters 10. In this embodiment, there are three insertion holes B8, respectively suitable for water meters 10 with dimensions of φ20, φ25, and φ40.

[0033] like Figure 9 As shown, when replacing water meter 10, hold handle 1 with one hand and place the fixed rod 2 and telescopic rod 3 on the front and rear sides of water meter 10. Then adjust the distance between telescopic rod 3 and fixed rod 2. When telescopic rod 3 moves relative to fixed rod 2 to the position of water meter 10 of the corresponding size, insert pin 9 into socket A7 and the corresponding socket B8 to fix telescopic rod 3 and fixed rod 2. Finally, use a wrench with the other hand to tighten the connector connected to water meter 10, which greatly improves the efficiency of meter replacement.
