DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings:

[0024] The directional nouns involved in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly specified and limited, the terms "setting", "installation", "connection", etc. should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0025] like Figures 1 to 3 The anti-private disassembly water meter shown in the figure includes: a host 100, a locking device 110, a water meter body 200, and a seat 300, wherein the locking device 110 includes a first locking component 130 and a second locking component 140, wherein the first locking component 130 is movably installed in the host 100, and the second locking component 140 is movably installed in the water meter body 200; a matching groove is provided on the side wall opposite to the water meter body 200, and the first locking component 130 protrudes into the water meter body 200 along the groove, and locks the connection between the host 100 and the water meter body 200; a matching through groove is provided on the side wall opposite to the water meter body 200 and the seat 300, and the second locking component 140 protrudes into the seat 300 along the through groove, and locks the connection between the water meter body 200 and the seat 300; a driving component 120 is also installed in the host 100, and is movably connected to the first locking component 130 and the second locking component 140.

[0026] Optionally, a plurality of grooves are provided on one side of the water meter body 200 facing the host 100, which are engaged with the host 100. In this way, the connection stability between the water meter body 200 and the host 100 can be improved, and the connection strength between the two can be further improved.

[0027] like Figure 3 and Figure 4As shown, the driving assembly 120 includes a driving motor 121, a connecting rod 122, a first driving gear 123, and a second driving gear 124. The driving motor 121 is fixed in the host 100, and the connecting rod 122 is installed on the power output end thereof; the first driving gear 123 is fixed in the middle of the connecting rod and meshes with the first locking assembly 130; the second driving gear 124 is fixed at one end of the connecting rod 122 away from the driving motor 121, and extends into the water meter body 200, and meshes with the second locking assembly 140; wherein the first driving gear 123 is located in the host 100. In this way, the host 100 can synchronously control the first locking assembly 130 and the second locking assembly 140 through a driving motor 121. When the driving motor 121 rotates, the first locking assembly 130 and the second locking assembly 140 can be synchronously locked or unlocked under the drive of the first driving gear 123 and the second driving gear 124. Not only the utilization rate of the driving motor 121 is improved, but also the synchronization rate of the operation of the first locking assembly 130 and the second locking assembly 140 is improved.

[0028] like Figure 4 As shown, the first locking components 130 are provided in a total of multiple groups, each group has two, and the structure is the same, and the upper and lower layers are arranged oppositely; one end of the first locking component 130 is provided with a hook, and the hook passes through the slot on the side wall of the host 100 and extends to the outside of the host 100; the other end is provided with a gear rail and meshes with the first driving gear 123. In this way, with the cooperation of the driving motor 121 and the first driving gear 123, the hooks set on the first locking components 130 are gradually tightened as the first locking components 130 move in opposite directions, until the hooks completely embrace the side wall of the water meter body 200. Thereby, the locking operation between the host 100 and the water meter body 200 is completed. On the contrary, if unlocking is required, the reverse operation can be performed.

[0029] like Figures 4 to 6 As shown, the second locking assembly 140 includes a movable ring 141 and a stationary ring 144. The stationary ring 144 is fixedly connected to the inner bottom plate of the water meter body 200. The movable ring 141 is installed on the top of the stationary ring 144, and a tooth 142 is provided on the top of the movable ring 141. In this way, the stationary ring 144 limits the movable ring 141. Under the cooperation of the tooth 142 and the second driving gear 124, the movable ring 141 set on the top of the stationary ring 144 can rotate along the stationary ring 144. This avoids the accidental situation that the movable ring 141 is offset or separated from the stationary ring 144 during the rotation process.

[0030] like Figure 5 and Figure 6As shown, the movable ring 141 is provided with a movable groove 143 which runs from one side to the other side, and a locking hook 1431 is installed in the movable groove 143. Thus, one end of the locking hook 1431 is hinged in the movable groove 143, and the other end is a free end. Under the action of its own weight and gravity, the free end can rotate toward the stationary ring 144.

[0031] like Figure 5 and Figure 6 As shown, the stationary ring 144 and the bottom plate of the water meter body 200 are provided with a through groove 400 that penetrates from one side to the other side, and the through groove 400 is connected to the movable groove 143, so that the lock hook 1431 is connected to the seat body 300. In this way, the through groove 400 connected to the movable groove 143 enables the free end of the lock hook 1431 to be connected to the seat body 300 at its front end after rotation, thereby completing the locking between the water meter body 200 and the seat body 300, and the water meter body 200 and the seat body 300 cannot be easily separated under the action of abnormal disassembly means. The anti-private disassembly effect between the two is effectively improved.

[0032] Optionally, the diameter of the movable groove 143 is larger than the diameter of the through groove 400, so that the lock hook 1431 can rely on the diameter difference between the movable groove 143 and the through groove 400, and in the unlocked state, as the movable ring 141 rotates, the bottom of the lock hook 1431 is lifted up by the edge of the through groove 400, so that the lock hook 1431 is separated from the seat body 300, thereby achieving the purpose of unlocking.

[0033] like Figure 1 and Figure 2 As shown, a battery compartment 102 is provided on one side of the host 100, and a display screen 103 and a card reading area 104 are provided on the top of the host 100. Thus, by filling multiple batteries in the battery compartment 102, the electronic components of the host are provided with the power required for operation, including the display screen 103, the card reading area 104, and the driving component 120.

[0034] Optionally, the card reading area 104 needs to cooperate with an external magnetic card to control the working state of the drive assembly 120. In this way, the drive assembly 120 can only be controlled by the staff using a specific magnetic card to complete the locking or unlocking operation of the locking device 110.

[0035] like Figure 2 As shown, a plurality of connecting arms 101 are extended from the outer wall of the main unit 100 and connected to the water meter body 200. In this way, the connecting arms 101 are engaged with the grooves to increase the connection strength between the main unit 100 and the water meter body 200.

[0036] like Figure 2As shown, a plurality of sealing rings are provided at the connection between the seat body 300 and the water meter body 200, respectively located on both sides of the through groove 400. The provided sealing rings not only improve the sealing performance of the connection between the water meter body 200 and the seat body 300, but also reduce the probability of the second locking assembly 140 being corroded by water.

[0037] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
