Description

Technical Field

[0001] The utility model relates to the technical field of metering devices, in particular to a metering communication module with a data security function. Background Art

[0002] A metering communication module with a data security function is a communication component specifically designed for intelligent metering systems. It is not only responsible for data collection and transmission but also includes security measures to ensure the integrity and confidentiality of data during transmission. Such modules are commonly found in intelligent metering devices such as smart electricity meters, smart water meters, and smart gas meters, and they are key components of modern smart grids, smart water systems, and smart gas networks.

[0003] After retrieval, a protective cover for an ultrasonic metering module with the authorization announcement number CN218724402U. The ultrasonic metering module has an ultrasonic flow channel air inlet and an ultrasonic flow channel air outlet, including a hollow-structured cover body. The ultrasonic metering module is installed inside the cover body. The cover body is provided with a cover body air inlet and a cover body air outlet. The ultrasonic flow channel air inlet is arranged corresponding to the cover body air inlet, and the ultrasonic flow channel air outlet is arranged corresponding to the cover body air outlet. This protective cover has a clever structure and is easy to install. By installing the ultrasonic metering module inside the cover body, the probability of the ultrasonic metering module being damaged can be effectively reduced, thereby reducing the probability of gas theft and ensuring the measurement results of the ultrasonic metering module. However, when the above technical solution is actually used, there are still the following deficiencies:

[0004] In the prior art, the installation of the protective cover or housing of the metering module is usually carried out through several bolts. During the installation process, it is necessary to ensure that the threaded holes of the two components are completely aligned, which requires extra time and effort for the staff to operate, especially in complex on-site conditions or narrow spaces. Secondly, each bolt needs to be tightened one by one, which not only increases the installation time but also requires ensuring the tightening force and sequence of each bolt to avoid affecting the quality and stability of the final assembly. Such an operation process requires frequent bending, wrist twisting and other actions, which are likely to cause physical fatigue and discomfort to the staff, especially more obvious in long-term or high-frequency installation operations. And when it is necessary to maintain or replace the internal components of the protective cover or housing, due to the large number of bolts and complex operations, the disassembly and reinstallation processes are time-consuming, which affects the usability and maintenance efficiency of the equipment and prolongs the suspension time of the metering device.

[0005] Therefore, it is necessary to design a metering communication module with a data security function to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to propose a metering communication module with a data security function to solve the disadvantages existing in the prior art.

Specific Embodiment

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Refer to Figures 1 - 5, a metering communication module with data security functions, including a housing 1. A circuit board 2 is fixed inside the housing 1. An installation frame 3 is fixed at the opening edge of the housing 1. The housing 1 and the installation frame 3 are integrally formed, and the inner size of the installation frame 3 is adapted to the opening of the housing 1 to ensure the structural stability of the device. A cover plate 4 adapted to the inner size of the installation frame 3 is provided inside the installation frame 3. Two handles are fixed on the cover plate 4 to facilitate the staff to take the cover plate 4. A positioning frame 5 is fixed on the inner side of the installation frame 3. The positioning frame 5 plays a role in limiting the position of the cover plate 4, enabling the cover plate 4 to be smoothly inserted into the installation frame 3. Slots 6 are opened on both inner sides of the installation frame 3. Placement grooves 8 are provided on both side walls of the cover plate 4. A clamping block 7 is slidably connected inside the placement groove 8. The width of the clamping block 7 is greater than the inner width of the slot 6. In this way, a part of the clamping block 7 is located inside the placement groove 8 and a part is located inside the slot 6, so that the cover plate 4 can be firmly assembled on the installation frame 3. The two clamping blocks 7 are respectively opposite to the two slots 6, and the size of the clamping block 7 is adapted to the slot 6. A moving component for driving the clamping block 7 to move is provided inside the cover plate 4.

[0026] Refer to Figure 3 and Figure 4 , the moving component includes a cavity 10 provided inside the cover plate 4. Two moving plates 11 are provided inside the cavity 10. A connecting rod 9 is fixed on the moving plate 11. The end of the connecting rod 9 far from the moving plate 11 extends into the interior of the placement groove 8, and the connecting rod 9 is fixed to the clamping block 7. The connecting rod 9 is slidably connected to the cover plate 4. Two springs 12 are jointly provided between the moving plate 11 and the inner side of the cavity 10. The two springs 12 are respectively located on both sides of the connecting rod 9 to ensure the uniform force of the moving plate 11. A turntable 13 is provided between the two moving plates 11. A screw rod 14 is fixed at the center position of the turntable 13. One end of the screw rod 14 extends outside the cover plate 4, and the screw rod 14 is threadedly connected to the cover plate 4. Two extrusion blocks 15 are fixed on the side wall of the turntable 13. The side wall of the extrusion block 15 is provided with an arc surface, which can reduce the friction between the extrusion block 15 and the moving plate 11.

[0027] Refer to Figure 1 , an anti-theft component for enhancing the anti-theft function of the device is provided on the cover plate 4. The anti-theft component includes a fixed cylinder 16 fixedly connected to the surface of the cover plate 4. A lock head 17 is provided inside the fixed cylinder 16. The lock head 17 is fixed to the screw rod 14. The lock head 17 is located inside the fixed cylinder 16 to prevent the staff from directly contacting the screw rod 14. The shape of the lock head 17 can be customized, and the lock head 17 is equipped with a corresponding key. The key can extend into the fixed cylinder 16. In this way, the anti-theft performance of the device can be enhanced, the security of data transmission of the metering device can be enhanced, and it is convenient to manage the metering devices in different areas.

[0028] Refer to Figure 5, a rubber frame one 18 is fixed on the side wall of the cover plate 4, and a rubber frame two 19 is fixed on the inner side of the installation frame 3. The rubber frame one 18 meshes with the rubber frame two 19. Since the rubber frame one 18 and the rubber frame two 19 are elastic, when the cover plate 4 is inserted into the installation frame 3, the rubber frame one 18 and the rubber frame two 19 are deformed and meshed with each other. On the one hand, this can fix the cover plate 4 and increase the stability of the connection between the cover plate 4 and the installation frame 3. Secondly, the rubber frame one 18 and the rubber frame two 19 can play a sealing role, improve the waterproof effect of the device, and thus extend the service life of the device.

[0029] The specific working principle of the present utility model is as follows:

[0030] When it is necessary to assemble the cover plate 4 and the housing 1, the staff presses the cover plate 4 into the installation frame 3. Under the limiting action of the positioning frame 5, the cover plate 4 can be flatly attached to the installation frame 3. Then, the screw rod 14 is rotated. Since the screw rod 14 is threadedly connected to the cover plate 4, the screw rod 14 will drive the turntable 13 and the extrusion block 15 to move towards the inside of the cavity 10 while rotating. When the two extrusion blocks 15 are respectively facing the two moving plates 11, the two extrusion blocks 15 will respectively squeeze the two moving plates 11, so that the connecting rod 9 and the clamping block 7 move away from the cavity 10, and then a part of the clamping block 7 can move into the inside of the clamping groove 6, thus realizing the fixation between the housing 1 and the cover plate 4. On the contrary, continue to rotate the turntable 13 to separate the extrusion block 15 from the moving plate 11. Under the elastic force of the spring 12, the connecting rod 9 and the clamping block 7 can move reversely to reset, and the clamping block 7 can be separated from the clamping groove 6, thus realizing the separation between the cover plate 4 and the installation frame 3. Such a design simplifies the installation process between the housing 1 and the cover plate 4, reduces the complexity of the operation, and improves the efficiency of the maintenance operation;

[0031] Furthermore, a lock head 17 is fixed at one end of the screw rod 14 outside the cavity 10. The shape of the lock head 17 can be customized, and the lock head 17 is equipped with a screwing key with a matching shape. When the staff performs maintenance, it is necessary to insert the matching key into the fixed cylinder 16 so that the key corresponds to the shape of the lock head 17. Then, rotate the key to drive the lock head 17 to rotate, and then drive the movement of the clamping block 7 to separate the cover plate 4 from the housing 1. Such a design can improve the anti-theft performance of the device and prevent non-staff from randomly opening the metering device and affecting the normal operation of the metering device.

[0032] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and should be covered by the protection scope of the present utility model.
