Description

Technical Field

[0001] This invention relates to the field of water meter anti-theft technology, and in particular to an anti-theft water meter for water meter protection. Background Technology

[0002] Because traditional water meters have a simple structure and lack anti-theft features, some people will disassemble the water meter and install it backwards in order to avoid or reduce water bills. To prevent this, the water meter should only allow water flow in one direction, which can effectively prevent users from disassembling and reinstalling it backwards, and ultimately serve as an anti-theft measure.

[0003] Chinese patent document CN114383683A discloses an anti-theft structure for a water meter, including a water meter body. The water meter body has a right-side connection port and a left-side connection port at both ends. A stepped groove is formed on the end face of the right-side connection port. Multiple sets of connecting brackets are fixedly connected to the inner side of the right-side connection port. The other ends of the multiple sets of connecting brackets are all fixed at one point and fixedly connected to a central support column. A threaded connection port is provided on the inner side of the left-side connection port. The left-side connection port also includes a left-side connecting pipe detachably connected to the left-side connection port. A threaded connector is movably connected to the right side of the left-side connecting pipe. By providing a central support column on the inner side of the right-side connection port, after connection with the right-side connecting pipe, a unidirectional water flow effect can be achieved, preventing users from disassembling and reinstalling the meter themselves, thus providing an anti-theft function.

[0004] While this patented technology effectively prevents water theft in practical use, some people may violently disassemble the water meter, which could easily damage it. Therefore, in addition to preventing theft, the water meter should be clamped and secured to protect it, increase its stability, reduce the likelihood of malfunction, and ultimately extend its lifespan. Summary of the Invention

[0005] The main objective of this invention is to provide an anti-theft water meter for water meter protection, which can effectively solve the problem of water meter damage caused by shaking during disassembly.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In this invention, the anti-theft device prevents water meter theft by disassembling and reinstalling the meter to steal water. Initially, the water meter is mounted on the wall, with the compression column pressed against the driven block. When someone disassembles the water meter, the first compression spring springs forward, causing the compression column to slide and the driven block to spring upward. Simultaneously, the two second compression springs change from compressed to extended states, driving the driving column forward and moving the sliding block. Because the lifting groove is an inclined Z-shape, it allows... The sliding column slides on the inner surface of the lifting groove and the vertical groove, causing the receiving plate and the water baffle to move downwards, blocking the left and right sides of the water meter. At this time, even if non-staff members disassemble the water meter, they cannot install it, thus preventing water theft. If the water meter needs to be reinstalled, staff must be contacted to open the cover. Pulling the limit block will move the support plate, causing the driven block to be clamped by the fixing component again. At the same time, the movement of the limit block will cause the receiving plate and the water baffle to move upwards, allowing the water meter to be exposed on both sides for final installation, effectively preventing water theft.

[0019] 2. In this invention, the water meter can be fixed by using the clamping assembly. When non-staff members disassemble the water meter, they may violently disassemble it. Therefore, when the assembly is working, the linkage plate will move, causing the two L-shaped rods to slide on the inner surface of the triangular groove. Since the triangular groove is triangular, the L-shaped rods on both sides will move to the sides, causing the two clamping rings to move. When the two clamping rings are close to the main body, the main body is fixed, thereby preventing the water meter from being damaged and increasing the service life of the water meter.

Detailed Implementation

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] Example 1

[0033] like Figure 1-9 As shown, an anti-theft water meter for water meter protection includes a protective housing 1, a cover plate 3, and an anti-theft device 9. The protective housing 1 has mounting grooves 7 at both its left and right ends. Figure 2As shown, the protective housing 1 has a placement cavity 8 inside, and a body 10 is provided at the bottom of the placement cavity 8. The protective housing 1 and the cover plate 3 are movably connected. The cover plate 3 has a viewing window 4 in the middle, a handle 5 on the upper right side of the cover plate 3, and a protective lock 6 on the upper right rear side of the cover plate 3. Mounting seats 2 are provided on the upper and lower front left and right sides of the protective housing 1. The anti-theft device 9 is fixedly connected to the protective housing 1. The anti-theft device 9 is inside the protective housing 1 and passes through the front of the protective housing 1. The anti-theft device 9 works in conjunction with the body 10.

[0034] The anti-theft device 9 can prevent the main body 10 from being installed backwards to steal water. At the same time, it can clamp and fix the main body 10 to prevent shaking during disassembly and damage to the main body 10, thereby increasing the stability of the main body 10 and thus extending the service life of the water meter. The viewing window 4 can be used to observe the numbers on the main body 10, and the main body 10 can be reinstalled by opening the cover plate 3.

[0035] like Figure 3 As shown, the anti-theft device 9 includes two anti-theft housings 90 and a clamping assembly 93. The ends of the two anti-theft housings 90 that are far apart from each other are fixedly connected to the protective housing 1. The front of the ends of the two anti-theft housings 90 that are close to each other is provided with a sliding groove 94. The rear of the lower end of the two anti-theft housings 90 is provided with a through groove 95. The two anti-theft housings 90 are provided with an anti-theft assembly 91 inside. The two anti-theft assemblies 91 pass through the through groove 95 on the same side. The front of the two anti-theft housings 90 is provided with a compression assembly 92. The two compression assemblies 92 communicate with the protective housing 1 and the anti-theft housings 90. The two compression assemblies 92 cooperate with the anti-theft assembly 91 on the same side. The upper part of the two anti-theft assemblies 91 is fixedly connected to the clamping assembly 93. The clamping assembly 93 is slidably connected to the two sliding grooves 94. The clamping assembly 93 cooperates with the body 10.

[0036] When the compression component 92 moves forward, it will activate the anti-theft component 91, thereby providing anti-theft protection for the left and right sides of the main body 10.

[0037] Specifically, such as Figure 4 The compression assembly 92 includes a compression plate 920, a compression seat 921 at the middle of the rear end of the compression plate 920, a compression column 922 at the rear end of the compression seat 921, and a first compression spring 923 at the front of the outer surface of the compression column 922. The compression column 922 is slidably connected to the protective housing 1 and the anti-theft housing 90. When the compression plate 920 is detached from the wall, the first compression spring 923 will extend forward, thereby causing the compression column 922 to move forward.

[0038] like Figure 5As shown, the anti-theft housing 90 includes a support plate 911 and a fixing component 913. A compression groove 914 is provided at the rear of the support plate 911. The support plate 911 is fixedly connected to the anti-theft housing 90. A driven component 910 is slidably connected to the inner surface of the compression groove 914. The upper front end of the driven component 910 is fixedly connected to the clamping component 93. A driving component 912 is provided at the rear end of the driven component 910. The rear end of the driving component 912 is fixedly connected to the anti-theft housing 90. The driving component 912 is fixedly connected to the fixing component 913. Both ends of the fixing component 913 are fixedly connected to the anti-theft housing 90. The fixing component 913 and the driven component 910 are used together.

[0039] For details, please refer to Figure 6 The driving component 912 includes an active component 9120 and a sliding component 9121. The rear end of the active component 9120 is fixedly connected to the anti-theft housing 90. The active component 9120 and the sliding component 9121 are slidably connected. The sliding component 9121 passes through the lower part of the active component 9120. The front of both ends of the active component 9120 is provided with a connecting plate 9122. The front end of each of the two connecting plates 9122 is provided with a second compression spring 9123. The two second compression springs 9123 are fixedly connected to the driven component 910. When the protective housing 1 is not disassembled, the two second compression springs 9123 will be compressed, so that the sliding component 9121 does not block the two sides of the body 10.

[0040] Specifically, such as Figure 7 The active component 9120 includes an active housing 9101. Vertical grooves 9102 are provided at the front of both the left and right ends of the active housing 9101. The rear end of the active housing 9101 is fixedly connected to the anti-theft housing 90. Both vertical grooves 9102 are slidably connected to the sliding component 9121. The sliding component 9121 passes through the lower part of the active housing 9101.

[0041] The sliding component 9121 includes a sliding block 9103 and a receiving plate 9106. The sliding block 9103 is slidably connected to the active housing 9101. The sliding block 9103 has lifting grooves 9104 on both the left and right sides. The two lifting grooves 9104 are inclined Z-shaped. The receiving plate 9106 is in the middle of the sliding block 9103. The upper part of both the left and right ends of the receiving plate 9106 is provided with sliding columns 9105. The two sliding columns 9105 are slidably connected to the two vertical grooves 9102 and the two lifting grooves 9104. The lower end of the receiving plate 9106 is provided with a baffle plate 9107. The baffle plate 9107 is used in conjunction with the body 10. The front middle of the fixed plate 9130 is provided with an active column 9108. The front end of the active column 9108 is fixedly connected to the driven component 910. The front part of the outer surface of the active column 9108 is fixedly connected to the fixed component 913.

[0042] Because the lifting groove 9104 is inclined in a Z-shape, the two sliding columns 9105 will slide on the inner surface of the lifting groove 9104 and the vertical groove 9102, thereby causing the receiving plate 9106 and the water baffle 9107 to move up and down, thus preventing theft of the main body 10.

[0043] like Figure 8 As shown, the driven component 910 includes a limiting block 9110, a driven plate 9111 at the lower end of the limiting block 9110, the driven plate 9111 is fixedly connected to the driving column 9108, the driven plate 9111 is slidably connected to the compression groove 914, a driven groove 9113 is opened at the lower front end of the driven plate 9111, a top plate 9114 is provided at the top of the driven groove 9113, a third compression spring 9115 is provided at both the front and rear ends of the lower end of the top plate 9114, and a driven block 9116 is provided at the lower end of the two third compression springs 9115;

[0044] When the compression column 922 is no longer in close contact with the driven block 9116, the driven block 9116 will slide on the inner surface of the driven groove 9113, thereby causing the driven block 9116 to move upward, so that the body 10 cannot be used when non-staff members reinstall the protective housing 1.

[0045] For details, please refer to Figure 9 The fixing component 913 includes a fixing plate 9130 and two fixing posts 9133. The fixing plate 9130 is fixedly connected to the active post 9108. The front end of the fixing plate 9130 is provided with a driving plate 9131. The driving plate 9131 is provided with inclined grooves 9132 on both the left and right sides. The front part of the two inclined grooves 9132 is inclined towards the middle. The inner surface of the two inclined grooves 9132 is provided with a driving post 9135. The lower end of the two driving posts 9135 is provided with a rectangular block 9134. The two fixing posts 9133 are slidably connected to the two rectangular blocks 9134. The upper end of the two driving posts 9135 is provided with a clamping plate 9136.

[0046] Since the front of the two inclined grooves 9132 are inclined towards the middle, when the fixed plate 9130 moves, the two driving columns 9135 will slide on the inner surface of the inclined grooves 9132 on the same side, thereby causing the two clamping plates 9136 to move to both sides.

[0047] The specific implementation method is as follows: When the protective shell 1 is not disassembled, the compression plate 920 will be pressed against the wall, the first compression spring 923 will be compressed, so that the compression column 922 will be pressed against the driven block 9116, and the driven block 9116 will be clamped by the two clamping plates 9136. At this time, the two second compression springs 9123 will also be compressed, so that the driving column 9108 will move backward, and the water baffle 9107 will not block the left and right sides of the body 10.

[0048] However, when unauthorized personnel disassemble the device, the four mounting bases 2 will move away from the wall, causing the compression plate 920 to no longer be in close contact with the wall. At this time, the first compression spring 923 will extend forward, causing the compression column 922 to move forward and no longer be in close contact with the driven block 9116. The driven block 9116 will then slide upward on the inner surface of the driven groove 9113. The two third compression springs 9115 are also compressed, and simultaneously, the two second compression springs 9123 will move forward, thereby driving the driving column 9108 forward, which in turn drives the sliding block 9103 in the lifting groove 9104 and the two vertical grooves 9104. The inner surface of 102 moves, causing the receiving plate 9106 and the baffle plate 9107 to move downwards, blocking the left and right sides of the main body 10 to prevent reverse installation. If the main body 10 is to be reinstalled, the staff must be contacted to open the cover plate 3 with a key, and then the limit block 9110 is pulled to the right to move the baffle plate 9107 upwards. At the same time, the fixing component 913 will move, thereby clamping the driven block 9116. Meanwhile, the four mounting seats 2 can be used to reinstall the protective shell 1 on the wall. The compression column 922 will be compressed again by the compression of the first compression spring 923 and then press tightly against the driven block 9116. At this time, the installation is completed.

[0049] Example 2

[0050] This embodiment further improves the clamping assembly 93 based on Embodiment 1, such as... Figure 10 As shown, during disassembly, in order to prevent unauthorized personnel from violently disassembling the body, the body 10 is clamped and fixed to reduce the damage to the body 10 caused by shaking, thereby extending the service life of the body 10.

[0051] like Figure 10 As shown, the clamping assembly 93 includes a linkage plate 930, which is fixedly connected to the driven assemblies 910 on the left and right sides. A vertical plate 931 is provided at the middle of the lower end of the linkage plate 930, and a linkage block 932 is provided at the lower end of the vertical plate 931. A triangular groove 933 is provided at the upper end of the linkage block 932. The triangular groove 933 is triangular in shape. A load-bearing plate 934 is provided at the front of the lower end of the linkage block 932. The load-bearing plate 934 is slidably connected to the protective shell 1. L-shaped rods 935 are provided on both the left and right sides of the triangular groove 933. A clamping ring 936 is provided at the rear end of each of the two L-shaped rods 935. The two clamping rings 936 are used in conjunction with the body 10.

[0052] Since the two triangular grooves 933 are triangular, when the linkage plate 930 moves, it will drive the vertical plate 931 to move, thereby causing the two L-shaped rods 935 to move to the sides in opposite directions, thereby causing the clamping rings 936 on both sides to move in opposite directions, thus clamping and fixing the body 10, preventing shaking during the disassembly of the protective shell 1, which would damage the body 10.

[0053] The specific implementation method is as follows: When the two limit blocks 9110 move, the linkage plate 930 will move, thereby causing the vertical plate 931 to move, which in turn drives the linkage block 932 to move, thereby causing the two L-shaped rods 935 to move on the inner surface of the triangular groove 933, thereby driving the two clamping rings 936 to move, so that the two clamping rings 936 are tightly attached to the outer surface of the body 10, thereby fixing and clamping the body 10, preventing shaking during disassembly and thus preventing damage to the body 10, and increasing the service life of the body 10.
