[0002] The non-magnetic remote water meter is a modern water meter technology, which realizes the remote monitoring and management of water meter data through the principle of wireless transmission. Compared with the traditional magnetic remote water meter, the non-magnetic remote water meter has higher safety and stability, and at the same time reduces the influence and damage of magnetism on the water meter.

[0003] The non-magnetic remote water meter mainly includes a water meter body, an intelligent module and a meter cover. The intelligent module integrates structures such as a data signal transmitter, a collector and a power supply. During assembly, the meter cover is first fixed on the water meter body, and then the intelligent module is installed on the meter cover; in order to facilitate the replacement of the intelligent module in the later stage, the intelligent module and the meter cover are connected by screws. However, the screw connection method enables others to easily remove the intelligent module from the meter cover with a screwdriver, resulting in property losses of the household and the inability to upload water meter data in a timely manner, and there are certain potential safety hazards. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: to provide a non-magnetic remote water meter, which improves the problem that the intelligent module in the existing non-magnetic remote water meter is easily removed from the meter cover by others.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions: A non-magnetic remote water meter, including a water meter body, a protective cover and an intelligent module, wherein the water meter body is movably connected to the protective cover, and the intelligent module is movably connected to the protective cover; the protective cover is provided with a cover plate and a rotating block, the rotating block is connected to the protective cover, and the cover plate is rotatably connected to the rotating block to open or close the protective cover, and further includes connecting screws for connecting and fixing the water meter body, the protective cover and the intelligent module; a locking structure, including a locking block and a linkage assembly, the linkage assembly is respectively linked to the locking block and the rotating block; the locking block is movably arranged on the protective cover, and the locking block can be connected to the connecting screw to lock the connecting screw; when the cover plate closes the protective cover, the connecting screw is connected to the locking block; the rotating block is rotatably connected to the protective cover, the rotating direction of the cover plate is perpendicular to the rotating direction of the rotating block, and when the rotating block rotates, it can drive the locking block to separate from the connecting screw through the linkage assembly.

[0006] By adopting the above technical solution, during installation, the protective cover is first installed on the water meter body, and then the smart module is installed on the protective cover, and finally the connecting screws are screwed in to fix the water meter body, the protective cover and the smart module together; Due to the function of the locking block, after the installation is completed, the cover is in a state of closing the protective cover. At this time, the locking block is connected to the connecting screws and locks the connecting screws. Outsiders cannot remove the smart module through the connecting screws, which plays a good role in protection and anti-loss. When the smart module needs to be replaced or repaired, the cover can be rotated so that the rotating block drives the locking block to move through the linkage assembly, so that the locking block is separated from the connecting screws. At this time, the connecting screws can be easily removed, and the method of unlocking by rotating the cover is difficult for ordinary people to detect, and only maintenance personnel know it. Therefore, this method can effectively prevent the smart module from being maliciously removed.

[0007] The present invention is further configured as follows: after the cover plate is rotated to close the protective cover, the cover plate cooperates with the intelligent module, the rotating block is locked on the protective cover, and when the cover plate is rotated to a specified angle and the protective cover is opened, the rotating block rotates freely.

[0008] By adopting the above technical solution, the cover plate can only be rotated after being opened and offset from the smart module, thereby adding a safety step to the unlocking method and preventing the rotating block from being accidentally rotated.

[0009] The present invention is further configured as follows: the linkage assembly comprises a driving gear and a mating gear meshing with each other, the driving gear is arranged on the rotating block, the mating gear is rotatably connected in the protective cover, and the locking block is arranged at an eccentric position on the mating gear; The connecting screw has a locking groove that cooperates with the locking block. When the rotating block rotates, it can drive the locking block to enter or leave the locking groove, so that the locking block is connected to or separated from the connecting screw to lock or unlock the connecting screw.

[0010] By adopting the above technical solution, the rotating block drives the locking block to move by meshing the driving gear and the matching gear, and the connecting screw is locked by cooperating with the locking block and the locking groove to prevent its rotation, and the structure is simple and reliable.

[0011] The present invention is further configured as follows: the smart module is provided with a battery slot, and the smart module is threadedly connected with a battery cover at the opening of the battery slot.

[0012] By adopting the above technical solution, the intelligent module needs battery power to send data and display, the battery slot provides space for the battery, and the battery cover protects the battery.

[0013] The present invention is further configured that: the locking structure further includes an anti-opening rod, the anti-opening rod is movably arranged on the intelligent module, the anti-opening rod can be connected to the battery cover to lock the battery cover, and when the cover plate closes the protective cover, the anti-opening rod is connected to the battery cover; the anti-opening rod is linked with the linkage assembly, and when the rotating block rotates, it can drive the anti-opening rod to separate from the battery cover through the linkage assembly.

[0014] By adopting the above technical solution, the battery cover is threadedly connected to the intelligent module, and an outsider can easily unscrew and remove the battery cover or damage the battery in the battery slot, which has certain potential hazards. The anti-opening rod can effectively prevent the battery cover from being maliciously opened by others, and the anti-opening rod is also driven by the cooperation of the rotating block and the linkage assembly, which can facilitate the subsequent replacement of the battery while making the preventive measures more concealed.

[0015] The present invention is further configured that: an anti-opening groove is formed at the threaded portion of the battery cover, and the anti-opening rod can pass through the inner wall of the intelligent module and be inserted and matched in the anti-opening groove so that the anti-opening rod is connected to the battery cover; A connecting block is arranged on the mating gear, and a connecting rod passing through the inner wall of the protective cover is arranged between the connecting block and the anti-opening rod. The two ends of the connecting rod are movably riveted to the connecting block and the anti-opening rod respectively. When the rotating block rotates, it can drive the connecting rod to pull the anti-opening rod so that the anti-opening rod disengages from the anti-opening groove and the intelligent module respectively.

[0016] By adopting the above technical solution, the battery cover is locked by the cooperation of the anti-opening rod and the anti-opening groove. By rotating the rotating block to drive the connecting rod to pull the anti-opening rod so that the anti-opening rod disengages from the anti-opening groove, the structure is simple and effective; when the battery cover needs to be locked again, turning the rotating block back for reset can make the anti-opening rod re-insert into the anti-opening groove.

[0017] The present invention is further configured that: the end face of the anti-opening rod at the outer side of the intelligent module is flush with the side wall surface of the intelligent module.

[0018] By adopting the above technical solution, the end face of the anti-opening rod being flush with the surface of the intelligent module plays a better concealing role and is not easily discovered by outsiders.

[0019] The present invention is further configured that: the water meter body is inserted and matched with the protective cover, and the intelligent module is inserted and matched with the protective cover.

[0020] By adopting the above technical solution, the insertion and matching method facilitates the installation of the protective cover and the intelligent module.

[0021] The beneficial effects of the present invention are: Due to the role of the locking block, after the installation is completed, the cover plate is in the role of closing the protective cover. At this time, the locking block is connected to the connecting screw and plays the role of locking the connecting screw.

DETAILED DESCRIPTION

[0029] In order to easily understand the technical means, creative features, achieved objectives and effects of the present invention, the present invention will be further described below with reference to specific drawings 1-6.

[0030] A non-magnetic remote water meter provided by the present application includes a water meter body 100, a protective cover 200, an intelligent module 300 and connecting screws 40. The water meter body 100 is a mechanical water meter, and the water meter body 100 includes a meter body, a movement kit disposed in the meter body for measuring water flow, and a transparent cover (not shown in the drawings). There is a chamber in the meter body, the movement kit is located in this chamber, and the transparent cover is located at the top of the meter body and encapsulates the movement kit in the meter body. The intelligent module 300 converts the rotation of the gears or the rotation of the pointer on the water meter body 100 into an electrical pulse signal through the principle of non-magnetic induction. The water meter body 100 is movably connected to the protective cover 200, the intelligent module 300 is movably connected to the protective cover 200, and the connecting screws 40 connect and fix the water meter body 100, the protective cover 200 and the intelligent module 300. The connecting screws 40 are threadedly connected to the outer shell part of the water meter body 100 without affecting the internal sealing of the water meter body 100. The protective cover 200 has a cover plate 20 and a rotating block 21. The rotating block 21 is connected to the protective cover 200, and the cover plate 20 is rotatably connected to the rotating block 21 to open or close the protective cover 200. After the cover plate 20 opens the protective cover 200, the data on the meter body can be observed.

[0031] Specifically, the water meter body 100 is in plug-in fit with the protective cover 200, and the intelligent module 300 is in plug-in fit with the protective cover 200 for easy installation. Openings are provided at both the upper and lower ends of the protective cover 200. The lower end of the protective cover 200 is connected to the top of the water meter body 100, and the water meter data is displayed on the top of the water meter body 100. The cover plate 20 can close or open the upper end opening of the protective cover 200 to protect the water meter or facilitate the owner to observe the water meter data. The intelligent module 300 has a battery slot 301, and a power supply battery (not shown in the drawings) of the intelligent module 300 is installed in the battery slot 301. A battery cover 30 is threadedly connected to the intelligent module 300 at the opening of the battery slot 301.

[0032] A non-magnetic remote water meter provided in the present application also includes a locking structure, which is located on the outside of the opening of the protective cover 200 and does not affect the intelligent module 300 from acquiring data from the water meter body 100. The locking structure includes a locking block 50 and a linkage component, and the linkage component is respectively linked to the locking block 50 and the rotating block 21. The locking block 50 is movably arranged on the protective cover 200, and the locking block 50 can be connected to the connecting screw 40 to lock the connecting screw 40; when the cover plate 20 closes the protective cover 200, the connecting screw 40 is connected to the locking block 50. The rotating block 21 is rotatably connected to the protective cover 200, and the rotation direction of the cover plate 20 is perpendicular to the rotation direction of the rotating block 21. When the rotating block 21 rotates, it can drive the locking block 50 to separate from the connecting screw 40 through the linkage component. Due to the function of the locking block 50, after the installation is completed, the cover 20 is in the function of closing the protective cover 200. At this time, the locking block 50 is connected to the connecting screw 40 and plays the role of locking the connecting screw 40. Outsiders cannot remove the smart module 300 through the connecting screw 40, which plays a good protection and anti-lost role. When the smart module 300 needs to be replaced or repaired, the cover 20 can be rotated to make the rotating block 21 drive the locking block 50 to move through the linkage component, so that the locking block 50 is separated from the connecting screw 40. At this time, the connecting screw 40 can be easily removed, and the method of unlocking by rotating the cover 20 is difficult for ordinary people to discover, and only maintenance personnel know it. Therefore, this method can effectively prevent the smart module 300 from being maliciously removed.

[0033] After the cover plate 20 is rotated to close the protective cover 200, the cover plate 20 cooperates with the smart module 300, and the rotating block 21 is locked on the protective cover 200. When the cover plate 20 is rotated to a specified angle and the protective cover 200 is opened, the rotating block 21 rotates freely. The cover plate 20 can only rotate after it is opened until it is offset from the smart module 300, which adds a safety step to the unlocking method and can prevent the rotating block 21 from being rotated accidentally.

[0034] The locking structure also includes an anti-opening rod 60, which is movably arranged on the smart module 300. The anti-opening rod 60 can be connected to the battery cover 30 to lock the battery cover 30. When the cover plate 20 closes the protective cover 200, the anti-opening rod 60 is connected to the battery cover 30; the anti-opening rod 60 is linked to the linkage assembly, and when the rotating block 21 rotates, the anti-opening rod 60 can be driven to separate from the battery cover 30 through the linkage assembly. The battery cover 30 and the smart module 300 are connected by threads, and an outsider can easily unscrew the battery cover 30 and take away or destroy the battery in the battery slot 301, which has certain hidden dangers. The anti-opening rod 60 can effectively prevent the battery cover 30 from being maliciously opened by others, and the anti-opening rod 60 is also driven by the cooperation of the rotating block 21 and the linkage assembly, which can facilitate the subsequent replacement of the battery and make the preventive measures more concealed.

[0035] Specifically, the linkage assembly includes a driving gear 70 and a matching gear 71 that mesh with each other. The driving gear 70 is arranged on the rotating block 21. The rotating block 21 has a rotating shaft. The driving gear 70 is fixed on the rotating shaft. The matching gear 71 is rotatably connected to the protective cover 200. The connecting screw 40 has a locking groove 401 that cooperates with the locking block 50. The locking block 50 is fixed at an eccentric position on the matching gear 71. When the rotating block 21 rotates, it can drive the locking block 50 to rotate around the axis of the matching gear 71 to enter or leave the locking groove 401, so that the locking block 50 is connected or separated from the connecting screw 40 to lock or unlock the connecting screw 40. The thread of the battery cover 30 is provided with an anti-opening groove 302, and the opening direction of the anti-opening groove 302 is perpendicular to the axis of the battery cover 30. The anti-opening rod 60 can pass through the inner wall of the smart module 300 and then be plugged and matched in the anti-opening groove 302, so that the anti-opening rod 60 is connected to the battery cover 30. The smart module 300 also includes a housing 31, on which a slideway is provided for slidingly cooperating with the anti-opening rod 60, and the slideway is connected to the anti-opening slot 302. In this embodiment, the slideway is a short slideway, and the anti-opening rod 60 passes through the short slideway before entering the anti-opening slot 302. The short slideway on the housing 31 plays a guiding and positioning role for the anti-opening rod 60; the slideway length can be customized according to the style type, and the anti-opening rod 60 may be detached from the slideway during the movement, and the anti-opening rod 60 needs to be manually inserted into the slideway when resetting; a limit key can also be provided in the slideway to limit the maximum sliding distance of the anti-opening rod 60 and limit the detachment of the anti-opening rod 60. In other embodiments, the slideway can also be set as a long slideway, so that the anti-opening rod 60 is always in the slideway during the movement of the connecting rod 81. A connecting block 80 is provided at an eccentric position on the mating gear 71, and a connecting rod 81 passing through the inner wall of the protective cover 200 is provided between the connecting block 80 and the anti-opening rod 60. The two ends of the connecting rod (81) are respectively riveted to the connecting block (80) and the anti-opening rod (60), and a portion of the connecting rod 81 is exposed outside the protective cover 200. When the rotating block 21 rotates, it can drive the connecting rod 81 to pull the anti-opening rod 60, so that the anti-opening rod 60 is separated from the anti-opening groove 302 and the smart module 300. The end surface of the anti-opening rod 60 located outside the smart module 300 is flush with the side wall surface of the smart module 300.

[0036] It should be noted that after the cover plate 20 is opened and rotated a specified number of turns in one direction, it can jointly control the locking block 50 to disengage from the locking groove 401 and the anti-opening rod 60 to disengage from the anti-opening groove 302, and there is no interference between them. Due to the frictional force between the locking block 50 and the inner wall of the locking groove 401, when resetting for re-locking, rotate the cover plate 20 in the reverse direction until the cover plate 20 feels resistance. At this time, the locking block 50 has entered the locking groove 401, and the anti-opening rod 60 can also be driven by the connecting rod 81 to re-pass through the slideway on the housing 31 and return to the anti-opening groove 302. After the connecting screw 40 and the battery cover 30 are screwed in place, the anti-opening groove 302 and the locking groove 401 correspond to the anti-opening rod 60 and the locking block 50 respectively.

[0037] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and all these changes and improvements fall within the scope of the present invention claimed. The scope of the present invention claimed is defined by the appended claims and their equivalents.
