Technical Field

[0001] This utility model relates to the technical field of water meter disassembly and assembly devices, and in particular to a water meter copper cover disassembly and assembly device. Background Technology

[0002] Old water meters come in various sizes, making the removal and recycling of their copper covers relatively troublesome. A standardized copper cover clamp cannot be used for rotation and removal. While some meters can be removed using specific clamps, others are too old to be replaced with their original clamps, making removal impossible. Manufacturing individual clamps for each meter would be wasteful and cumbersome. Therefore, a unified copper cover removal and installation device is needed to accommodate various types of old water meters. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this utility model is to provide a water meter copper cover removal and installation device, which solves the problems of old water meters lacking specific copper cover clips for removal and the cumbersome removal process.

[0004] A water meter copper cover disassembly and assembly device according to this utility model includes a collar, an inner adjusting strip, and a rotating assembly for rotating the collar. The collar has symmetrical adjusting bolts screwed through its sidewalls. Each adjusting bolt has symmetrical square openings on its sidewalls, oriented axially upwards. A rotating block is inserted into each square opening, and the upper and lower surfaces of the rotating block are rotatably mounted on the top and bottom walls of the square opening via pins. Each rotating block has a through bolt hole, into which a compression bolt, screwed from the outside to the inside of the collar, is screwed. The inner adjusting strip includes two symmetrical arc-shaped... A steel plate and a rubber layer fixed to the inner side of the arc-shaped steel plate are provided. An installation block is fixed at the middle position of the outer side wall of the arc-shaped steel plate. Two installation blocks are rotatably sleeved on the ends of the adjusting bolts. Rotating parts are provided near both ends of the outer side wall of the arc-shaped steel plate. The end of the extrusion bolt inserted into the inner side of the collar is rotatably inserted into the rotating part. The rotating assembly includes a rotating ring, four inserts and a direction rotating rod. Four inserts are evenly fixed at the bottom of the rotating ring. Two direction rotating rods are symmetrically fixed on the outer side wall of the rotating ring. Four square slots matching the four inserts are evenly distributed on the collar.

[0005] In some embodiments of this utility model, when the inner adjusting strip is unfolded to its maximum angle, the outer diameter of the circle formed by the two inner adjusting strips is 4 / 5 of the inner diameter of the collar; when the inner adjusting strip is compressed and deformed to its minimum angle, the outer diameter of the circle formed by the two inner adjusting strips is 3 / 5 of the inner diameter of the collar.

[0006] In some other embodiments of this utility model, the adjustment bolt has a rotation distance range of 2cm, and the compression bolt has a rotation distance range of 3.5cm.

[0007] In some other embodiments of this utility model, the rotating component includes two mounting plates arranged symmetrically on top of each other and a plug-in rotating block. The plug-in rotating block is inserted between the two mounting plates and is rotatably connected to the plug-in rotating block by a pin passing through the mounting plate. The plug-in rotating block has a plug hole on its front side, and the inner end of the extrusion bolt is rotatably inserted into the plug hole.

[0008] In some other embodiments of this utility model, the inner and outer diameters of the rotating ring are the same as those of the collar, and the rotating ring, the four inserts and the directional rod are integrally die-cast.

[0009] In some other embodiments of this utility model, the inner surface of the rubber layer is provided with anti-slip ridges.

[0010] In this utility model, the size of the clamping circle is adjusted by the internal adjustment bar to clamp the copper cover of old water meters of different sizes, so as to solve the problem that different water meters cannot be removed because they are too old and there is no matching copper cover clamp. This removal device can remove the copper cover of many different models of old water meters and has strong applicability. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0018] Reference Figure 1-3 A water meter copper cover disassembly and assembly device includes a collar 2, an inner adjusting strip 5, and a rotating assembly for rotating the collar 2. The collar 2 has symmetrical adjusting bolts 3 that penetrate the sidewalls. Each adjusting bolt 3 has symmetrically symmetrical square openings 40 on its sidewalls, oriented axially upwards. A rotating block 41 is inserted into each square opening 40, and the upper and lower surfaces of the rotating block 41 are rotatably mounted on the top and bottom walls of the square opening 40 via pins. The rotating block 41 has a through bolt hole 411, and a clamping bolt 4 is screwed into the bolt hole 411, screwed from the outside of the collar 2 to the inside. The inner adjusting strip 5 includes two symmetrical arc-shaped steel plates 51. A rubber layer 52 is fixed to the inner side of the arc-shaped steel plate 51. An installation block 7 is fixed in the middle of the outer wall of the arc-shaped steel plate 51. Two installation blocks 7 are rotatably sleeved on the ends of the adjusting bolts 3. Rotating parts are provided near both ends of the outer wall of the arc-shaped steel plate 51. The end of the extrusion bolt 4 inserted into the inner side of the collar 2 is rotated into the rotating part. The rotating assembly includes a rotating ring 1, four inserts 12 and a direction rotating rod 11. Four inserts 12 are evenly fixed at the bottom of the rotating ring 1. Two direction rotating rods 11 are symmetrically fixed on the outer wall of the rotating ring 1. Four square slots matching the four inserts 12 are evenly distributed on the collar 2.

[0019] Place the collar 2 over the copper cover of the water meter (the inner adjusting clip is already inside the collar). First, rotate the adjusting bolts 3 on both sides, causing them to push the inner adjusting clip 5 inward until it presses against the copper cover. Then, rotate the pressing bolt 4 so that it inserts into the rotating part. Next, rotate the pressing bolt 4 to allow the inner adjusting clip 5 to grip the copper cover until it is fully gripped and completely adhered to the copper cover. Insert the four inserts 12 into the square slots. By rotating the direction rod 11, the rotating ring 1 rotates, thereby rotating the collar 2 and the inner adjusting clip 5. Because the inner adjusting clip 5 tightly grips the copper cover, the copper cover can be removed. This device is used for various old water meters without matching copper cover sleeves, and it is suitable for various models of old water meters.

[0020] When the inner adjusting strip is unfolded to its maximum angle, the outer diameter of the circle formed by the two inner adjusting strips is 4 / 5 of the inner diameter of the collar 2. When the inner adjusting strip is compressed and deformed to its minimum angle, the outer diameter of the circle formed by the two inner adjusting strips is 3 / 5 of the inner diameter of the collar 2.

[0021] The outer diameter of the copper cover is 3 / 5-4 / 5 of the inner diameter of the collar 2. The water meter needs to be removed, as the change is too large and inconvenient to adjust.

[0022] The adjustment bolt 3 has a rotation range of 2cm, and the clamping bolt 4 has a rotation range of 3.5cm. The difference between the maximum and minimum outer diameters of the copper cover of the old water meter is within 2cm.

[0023] The rotating component includes two mounting plates 61 arranged symmetrically on top of each other and a plug-in rotating block 6. The plug-in rotating block 6 is inserted between the two mounting plates 61 and is rotatably connected to the plug-in rotating block 6 by a pin passing through the mounting plate 61. The plug-in rotating block 6 has a plug hole on its front side, and the inner end of the extrusion bolt 4 is rotatably inserted into the plug hole.

[0024] The two mounting plates 61 are fixed at their tail ends to the outer wall of the arc-shaped steel plate 51 to form a U-shaped opening, and the plug-in rotating block 6 is rotatably installed inside the U-shaped opening.

[0025] The inner and outer diameters of the rotating ring 1 are the same as those of the collar. The rotating ring 1, the four inserts 12, and the directional rotating rod 11 are integrally die-cast. This integral design provides better stability, and being made of metal, it is less prone to deformation and breakage.

[0026] The inner surface of the rubber layer 52 is provided with anti-slip protrusions. This prevents slipping and provides high friction.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
