Description

Technical Field

[0001] This utility model relates to the technical field of ductile iron water meter boxes, specifically a ductile iron water meter box. Background Technology

[0002] Ductile iron water meter boxes are made of high-quality ductile iron, possessing extremely high strength and toughness. They can withstand accidental impacts and heavy pressure, such as collisions during construction or damage caused by human factors during daily use, without serious impact, providing robust and reliable protection for the water meter. Their surface undergoes special anti-corrosion treatment, such as epoxy asphalt paint or galvanizing, resulting in excellent rust and corrosion resistance. They can be used long-term in harsh environments such as damp basements and outdoors, without easily rusting or corroding, thus ensuring the service life of the water meter box and the normal operation of the water meter. The internal design of the ductile iron water meter box is reasonable, with a scientifically laid-out space, facilitating the installation, disassembly, maintenance, and reading of the water meter. The cover and body are usually connected by hinges, and some are also equipped with locks to ensure the security of the water meter.

[0003] However, in the existing technology, the device lacks a sealing mechanism during use, making it difficult to seal the connection between the water meter box body and the cover. This allows water and dust to easily enter the device. Furthermore, checking the water meter reading requires opening the heavy cover, making the device inconvenient to use. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a ductile iron water meter box, which solves the problems that when the device is in use, the lack of a sealing mechanism makes it difficult to seal the connection between the main body of the water meter box and the cover, allowing water and dust to easily enter the device. Moreover, when it is necessary to check the water meter reading, a heavy cover needs to be opened to view the water meter reading, making the device inconvenient to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ductile iron water meter box, comprising a water meter box body, a cover in contact with the interior of the water meter box body, a hinge fixedly connected to the cover, the hinge being fixedly connected to the water meter box body, a groove inside the cover, a sealing mechanism inside the cover, a handle fixedly connected to the upper end of the cover, a fixing sleeve fixedly connected to the upper end of the cover, a baffle slidably connected to the upper end of the fixing sleeve, a moving block fixedly connected to the upper end of the baffle, a sliding block slidably connected inside the fixing sleeve, a fixing rod slidably connected inside the sliding block, both ends of the fixing rod being fixedly connected to the fixing sleeve, a groove inside the sliding block, a slot inside the fixing sleeve, and the sliding block being fixedly connected to the baffle. By moving the baffle to the right, the movement of the baffle drives the sliding block and other components to move. After the baffle and other components move to the designated position, it becomes easier to view the water meter reading inside the device, making the device easy to use.

[0006] Preferably, the main body of the water meter box is made of ductile iron, and the groove is provided with ball bearings. The ball bearings contact the fixed rod. By designing the ball bearings, the sliding friction between the sliding block and the fixed rod can be converted into rolling friction, which greatly reduces frictional resistance. This reduces wear on both surfaces and extends service life, while also allowing the sliding block to slide more smoothly along the fixed rod, avoiding jamming and ensuring the stability of the structure.

[0007] Preferably, the slot is fitted with an elastic block, which is fixedly connected to the baffle. By designing the elastic block, its elastic deformation characteristics can be used to form a tight engagement with the slot, effectively limiting the displacement of the baffle in the horizontal and vertical directions, preventing the baffle from loosening or shifting during equipment operation, and ensuring the stability of the baffle.

[0008] Preferably, the sealing mechanism includes a screw, which is threadedly connected to the inside of the cover. A connecting sleeve is rotatably connected to the outside of the screw, and a bolt is threadedly connected to the inside of the connecting sleeve. An elastic connecting sleeve is fixedly connected to the lower end of the connecting sleeve. A sliding groove is formed inside the cover, and a guide block is slidably connected inside the sliding groove. The guide block is fixedly connected to the elastic connecting sleeve, and the cover is slidably connected to the elastic connecting sleeve. The elastic connecting sleeve is slidably connected to the water meter box body, and a sealing sleeve is fixedly connected to the lower end of the elastic connecting sleeve. The sealing sleeve is slidably connected to the water meter box body, and the cover is slidably connected to the sealing sleeve. By rotating the screw and the cover, a threaded movement occurs. The screw rotation drives the sealing sleeve and other components to move downward. The sealing sleeve moves downward and contacts a designated position on the water meter box body and the cover, thereby sealing the connection between the water meter box body and the cover and preventing water or dust from entering the device.

[0009] Preferably, a rotating block is fixedly connected to the upper end of the screw. The rotating block is made of iron. By designing the rotating block to be made of iron, the high strength, high hardness and wear resistance of iron can be fully utilized, making the rotating block less prone to deformation and breakage when subjected to rotational torque and friction, significantly improving its durability, reducing the frequency of component replacement and reducing maintenance costs.

[0010] Preferably, the screw has an annular groove inside, and a bolt is slidably connected inside the annular groove. By designing the bolt, the screw can be connected to the connecting sleeve.

[0011] Preferably, the guide block has a guide rod slidably connected inside, and the two ends of the guide rod are fixedly connected to the cover. By designing the guide rod, a precise axial movement trajectory can be provided for the guide block, strictly limiting the radial offset of the guide block, avoiding shaking or deviation from the preset path when it slides, ensuring that the guide block drives the associated components to achieve stable and precise displacement, thereby improving the operating accuracy of the entire device.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model designs components such as a screw, rotating block, connecting sleeve, bolt, annular groove, and elastic connecting sleeve. The rotating screw causes the cover to move in a threaded motion. The rotation of the screw drives the sealing sleeve and other components to move downward. The sealing sleeve moves downward and contacts the designated position of the water meter box body and the cover, thereby sealing the connection between the water meter box body and the cover and preventing water or dust from entering the device.

[0014] 2. This utility model incorporates components such as a fixed sleeve, baffle, moving block, sliding block, fixed rod, and groove. The moving baffle moves to the right, which in turn moves the sliding block and other components. Once the baffle and other components are in the designated position, it is easier to view the water meter readings inside the device, making the device easy to use. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5A ductile iron water meter box includes a main body 1 made of ductile iron. A cover 2 is located inside the main body 1, and a hinge 3 is fixedly connected to the cover 2. The hinge 3 is fixedly connected to the main body 1. A groove 4 is formed inside the cover 2, and a sealing mechanism 5 is provided inside the cover 2. A handle 6 is fixedly connected to the upper end of the cover 2. A fixing sleeve 71 is fixedly connected to the upper end of the cover 2. A baffle 72 is slidably connected to the upper end of the fixing sleeve 71, and a moving block 73 is fixedly connected to the upper end of the baffle 72. A sliding block 74 is slidably connected inside the fixing sleeve 71, and a fixing rod 75 is slidably connected inside the sliding block 74. Both ends of the fixing rod 75 are fixedly connected to the fixing sleeve 71. A groove 76 is formed inside the sliding block 74, and a ball bearing 77 is provided inside the groove 76. The ball bearing 77 contacts the fixing rod 75. By designing the ball bearing 77, the sliding block 74 can be connected to the fixing rod 75. The sliding friction between rods 75 is converted into rolling friction, which greatly reduces frictional resistance. This reduces surface wear and extends service life, while also allowing the sliding block 74 to slide more smoothly along the fixed rod 75, avoiding jamming and ensuring the stability of the structure. The fixed sleeve 71 has a slot 78 inside, and an elastic block 79 is engaged inside the slot 78. The elastic block 79 is fixedly connected to the baffle 72. By designing the elastic block 79, its elastic deformation characteristics can be used to form a tight engagement with the slot 78, effectively limiting the displacement of the baffle 72 in the horizontal and vertical directions, preventing the baffle 72 from loosening or shifting during equipment operation, and ensuring the stability of the baffle 72. The sliding block 74 is fixedly connected to the baffle 72. By moving the baffle 72 to the right, the movement of the baffle 72 drives the sliding block 74 and other components to move. After the baffle 72 and other components move to the designated position, it is easier to check the water meter reading in the device, making the device easy to use.

[0023] Please see Figure 4 The sealing mechanism 5 includes a screw 51. The screw 51 is threadedly connected to the inside of the cover 2. A rotating block 52 is fixedly connected to the upper end of the screw 51. The rotating block 52 is made of iron. By designing the rotating block 52 to be made of iron, the high strength, high hardness and wear resistance of iron can be fully utilized, making the rotating block 52 less prone to deformation and breakage when subjected to rotational torque and friction, significantly improving its durability, reducing the frequency of component replacement and reducing maintenance costs. A connecting sleeve 53 is rotatably connected to the outside of the screw 51. A bolt 54 is threadedly connected to the inside of the connecting sleeve 53. An annular groove 55 is opened inside the screw 51. The bolt 54 is slidably connected inside the annular groove 55. By designing the bolt 54, the screw 51 and the connecting sleeve 53 can be connected.

[0024] Please see Figure 4The lower end of the connecting sleeve 53 is fixedly connected to an elastic connecting sleeve 56. The inside of the cover 2 is provided with a sliding groove 57. A guide block 58 is slidably connected inside the sliding groove 57. A guide rod 59 is slidably connected inside the guide block 58. The two ends of the guide rod 59 are fixedly connected to the cover 2. By designing the guide rod 59, a precise axial movement trajectory can be provided for the guide block 58, strictly limiting the radial offset of the guide block 58, avoiding shaking or deviation from the preset path when it slides, and ensuring that the guide block 58 drives the associated components to achieve stable and precise displacement, thereby improving the operating accuracy of the entire equipment. The guide block 58 is fixedly connected to the elastic connecting sleeve 56, the cover 2 is slidably connected to the elastic connecting sleeve 56, the elastic connecting sleeve 56 is slidably connected to the water meter box body 1, and a sealing sleeve 510 is fixedly connected to the lower end of the elastic connecting sleeve 56. The sealing sleeve 510 is slidably connected to the water meter box body 1, and the cover 2 is slidably connected to the sealing sleeve 510. By rotating the screw 51, the cover 2 undergoes threaded movement. The rotation of the screw 51 drives the sealing sleeve 510 and other components to move downward. The sealing sleeve 510 moves downward and contacts the designated position of the water meter box body 1 and the cover 2, thereby sealing the connection between the water meter box body 1 and the cover 2 and preventing water or dust from entering the device.

[0025] The specific implementation process of this utility model is as follows: Before the device is used, rotate the rotating block 52. The rotation of the rotating block 52 drives the screw 51 to rotate. The rotation of the screw 51 causes threaded movement with the cover 2, thereby causing the screw 51 to generate relative displacement. The rotation of the screw 51 drives the connecting sleeve 53 and bolt 54 and other components to move downward. The downward movement of the connecting sleeve 53 drives the elastic connecting sleeve 56 to move downward. The downward movement of the elastic connecting sleeve 56 drives the guide block 58 and sealing sleeve 510 to move downward. The downward movement of the sealing sleeve 510 contacts the designated position of the water meter box body 1 and the cover 2, thereby sealing the connection between the water meter box body 1 and the cover 2 and preventing water or dust from entering the device.

[0026] When it is necessary to check the water meter reading inside the device, pull the moving block 73 to move it to the right side of the device. The movement of the moving block 73 causes the baffle 72 to move, the movement of the baffle 72 causes the sliding block 74 and the elastic locking block 79 to move, the movement of the sliding block 74 causes the groove 76 to move, the movement of the groove 76 causes the ball 77 to move, and the elastic locking block 79 moves and separates from the locking groove 78. After the baffle 72 and other components are moved to the designated position, it is easier to check the water meter reading inside the device, making the device easy to use.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
