Technical Field

[0001] This utility model relates to the field of water meter technology, specifically a water meter casing disassembly and assembly device. Background Technology

[0002] A water meter is an instrument that measures water flow, mostly the cumulative flow of water. Currently, most water meters in existing technology have a copper cover. When there is a problem with the dial or internal components of these water meters, it is inconvenient to disassemble them on site. They need to be disassembled and taken back to the company for testing and repair, and disassembly and assembly are carried out with the help of other tools. If you want to directly disassemble or install the copper cover on site, it is not only inconvenient to operate, but also time-consuming and laborious.

[0003] Therefore, the inventors aimed to solve the problem of designing a portable device that could disassemble and assemble the copper cover on-site, thereby reducing operational difficulty and improving efficiency. Utility Model Content

Detailed Implementation

[0019] The present invention will be further described below with reference to specific embodiments. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0020] Example 1: See Figs. 1 to 3This utility model discloses a water meter casing disassembly and assembly device, including a base 1, two symmetrically distributed slide rails 2 on the base 1, a slider 3 slidably disposed on the outer side of the slide rails 2, and a vertical plate 4 connected between the two sliders 3. Through the cooperation between the sliders 3 and the slide rails 2, the vertical plate 4 can be driven to slide along the direction of the slide rails 2. Limit bolts are provided at both ends of the slide rails 2 to prevent the sliders 3 from accidentally falling off.

[0021] A shaft hole is provided in the middle of the upright plate 4, and a bearing is provided inside the shaft hole. A spindle 5 passes through the bearing and is connected to one end of the spindle 5. A retaining spring is provided on the outside of the spindle 5. The retaining spring and the retaining block 11 are respectively provided on both sides of the upright plate 4. A boss structure is provided on the end face of the retaining block 11 that is connected to the spindle 5. A gasket is provided between the boss structure and the bearing. The retaining spring can prevent the spindle 5 from moving axially, which is convenient for operation. A sleeve 7 is provided on the outside of one end of the spindle 5. The sleeve 7 is connected to the spindle 5 by a connecting bolt 6 and a nut. The sleeve 7 has a mounting hole for the connecting bolt 6 to pass through on its circumferential surface. The spindle 5 has a through hole that matches the mounting hole. The connecting bolt 6 passes through both the mounting hole and the through hole. The connecting bolt 6 ensures the transmission connection between the sleeve 7 and the spindle 5. A handle 8 is connected to the circumferential surface of the sleeve 7. A silicone sleeve 9 is provided on the outer side of the end of the handle 8. Two symmetrically distributed support frames 14 are provided on the side of the slide rail 2. The handle 8, the spindle 5, and the locking block 11 form a lever principle structure. The locking block 11 can be operated with relatively little effort by operating the handle 8.

[0022] The locking block 11 is hollow in the middle. Eight evenly distributed slots 12 are provided on the inner circular sidewall of the locking block 11, and four evenly distributed inserts 13 are provided on the inner circular sidewall of the locking block 11. The copper cover of the water meter, according to its design, generally has two common structures: one with four evenly distributed plate-like protrusions on the circumference of the copper cover, and the other with four evenly distributed strip-shaped grooves on the circumference of the copper cover. Both are used to assist in the disassembly and installation of the copper cover. The locking block 11 of this utility model is provided with both slots 12 and inserts 13, which can meet the disassembly and installation requirements of both types of water meter copper covers. For installation requirements, slot 12 should be closer to the water meter installation position than insert block 13. If the copper cover of the water meter is designed with a plate-like protrusion, the handle 8 can be directly rotated to rotate the locking block 11, find the position of slot 12, and slide the vertical plate 4 so that slot 12 can be inserted into the protrusion on the copper cover. Then, rotate the handle 8 to install or remove the copper cover. If the copper cover of the water meter is designed with a groove, when using the locking block 11 to insert into the copper cover, the slot 12 should be pushed back so that the insert block 13 is closer to the copper cover and inserted into the groove on the copper cover for installation or removal.

[0023] The support frame 14 includes a base plate 17, and a bracket 15 is connected to the upper end of the base plate 17. A slot 16 is opened on one side end face of the bracket 15. A rubber pad is provided inside the slot 16. The axis of the slot 16 is on the same horizontal plane as the axis of the inner circle of the locking block 11. The two ends of the water meter workpiece 19 are respectively inserted into the slots 16 in the two support frames 14. The angle of the water meter workpiece 19 is rotated so that the axis of the copper cover coincides with the axis of the spindle 5 to complete the setting of the water meter.

[0024] To make this utility model more convenient to carry, a handle groove 18 is provided on the end face of the base 1 for easy hand carrying.

[0025] To make it easier to operate the handle 8 with tools such as hammers, a hammer pad 10 is provided at the tail of the handle 8 to withstand the impact of tools such as hammers and wrenches, thereby reducing the intensity of manual force application.

[0026] This utility model adopts a novel structural design, combining portability and ease of operation. Through the cooperation of the locking block 11 and the support frame 14, the water meter is restricted while the copper cover of the water meter can be easily disassembled or installed by operating the locking block 11 through the handle 8. This achieves portability, enables on-site disassembly and assembly of the copper cover, reduces the difficulty of operation, and improves efficiency.
