Description

Technical Field

[0001] This utility model belongs to the field of anti-theft instrument technology, and in particular relates to a new type of anti-theft instrument seal. Background Technology

[0002] Instruments, as specialized devices used for precise measurement, intuitive display, reliable recording, intelligent control, and fine adjustment of various parameters such as physical or chemical quantities, play an indispensable and crucial role in many fields, including industry, agriculture, scientific research, medicine, and transportation. Anti-theft instrument seals, on the other hand, are special devices designed specifically to protect instrument security and are widely used in common civilian metering instruments such as water meters, electricity meters, and gas meters. They not only strictly prevent illegal tampering with instrument data and eliminate unauthorized use of the instrument, but also effectively protect the instrument from physical damage caused by external impacts.

[0003] While existing anti-theft instrument seals, once installed on the instrument, can prevent relative displacement between the upper and lower cover plates in the horizontal dimension, ensuring a certain degree of stability, there is still a certain gap between the two cover plates in the vertical direction. This gap provides an opportunity for unauthorized operators to pry or damage the seal with tools. Furthermore, this gap allows dust, moisture, or other contaminants to enter the seal, affecting the normal operation of the instrument and causing corrosion. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of anti-theft instrument seal. By engaging the L-shaped teeth on the upper cover plate with the L-shaped groove on the lower cover plate, and simultaneously embedding a sealing ring in both the first and second sealing ring grooves, the upper and lower cover plates are fitted together. This solves the problem that existing anti-theft instrument seal devices allow dust, moisture, or other contaminants to enter the seal due to the gap between the two cover plates, affecting the normal operation and service life of the instrument.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a novel anti-theft instrument seal, comprising an upper cover plate and a lower cover plate. The inner circumferential side of the upper cover plate has a plurality of L-shaped locking teeth fixedly connected in a circular array. The inner circumferential side of the lower cover plate has a plurality of L-shaped locking grooves formed in a circular array. The L-shaped locking teeth and L-shaped locking grooves engage with each other. A first sealing ring groove is fixedly connected to the top of the upper cover plate, and a second sealing ring groove is fixedly connected to the bottom of the lower cover plate. The first sealing ring groove and the second sealing ring groove are symmetrically arranged, and a sealing ring is embedded in both the first sealing ring groove and the second sealing ring groove.

[0007] The present invention is further provided that a transparent observation window is fixedly installed on the inner circumferential side of the upper cover plate.

[0008] The present invention is further configured such that a connecting plate is rotatably fitted to the top of the transparent observation window.

[0009] The present invention is further configured such that an L-shaped sleeve plate is fixedly connected to the periphery of the lower cover plate, and an extension plate is slidably fitted inside the L-shaped sleeve plate, and the extension plate is rotatably fitted with the connecting plate.

[0010] The present invention is further configured such that the outer peripheral sides of the upper cover plate and the lower cover plate are fixedly connected with fixing holes, and the two fixing holes are arranged symmetrically.

[0011] The present invention is further provided that a drainage groove is provided through the outer periphery of the lower cover plate.

[0012] This utility model has the following beneficial effects:

[0013] This invention achieves a seal by inserting the sealing ring into the second sealing ring groove and inserting the L-shaped teeth on the upper cover plate into the corresponding L-shaped grooves, thus making the upper and lower cover plates fit together. The two ends of the sealing ring are respectively inserted into the first and second sealing ring grooves. Then, by rotating the upper cover plate, the L-shaped teeth engage with the tail ends of the L-shaped grooves. At this point, the upper and lower cover plates are fully engaged, and the sealing ring provides a sealing effect, preventing external dust and moisture from entering the seal through the gap between the two cover plates. This design offers high practicality.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation

[0024] Please see Figure 1-4 This utility model is a novel anti-theft instrument seal, including an upper cover plate 1 and a lower cover plate 2. The inner circumferential side of the upper cover plate 1 is fixedly connected with a plurality of L-shaped teeth 3 in a circular array. The inner circumferential side of the lower cover plate 2 is provided with a plurality of L-shaped slots 4 in a circular array. The L-shaped teeth 3 and the L-shaped slots 4 engage with each other. A first sealing ring groove 5 is fixedly connected to the top of the upper cover plate 1. A second sealing ring groove 6 is fixedly connected to the bottom of the lower cover plate 2. The first sealing ring groove 5 and the second sealing ring groove 6 are symmetrically arranged. A sealing ring 7 is embedded in both the first sealing ring groove 5 and the second sealing ring groove 6.

[0025] First, fix the lower cover plate 2 onto the instrument. Then, insert the sealing ring 7 into the second sealing ring groove 6. Align each L-shaped tooth 3 on the upper cover plate 1 with the corresponding L-shaped groove 4 and insert it. At this time, the upper cover plate 1 and the lower cover plate 2 are in contact. The two ends of the sealing ring 7 are respectively inserted into the first sealing ring groove 5 and the second sealing ring groove 6. Then rotate the upper cover plate 1 so that the L-shaped tooth 3 is inserted into the tail end of the L-shaped groove 4. At this time, the upper cover plate 1 and the lower cover plate 2 are engaged, and the sealing ring 7 also plays a sealing role, thereby preventing external dust and moisture from entering the seal through the gap between the two covers. If it is necessary to open the seal, the upper cover plate 1 can be rotated in the opposite direction to separate the upper cover plate 1 from the lower cover plate 2.

[0026] Specifically, a transparent observation window 8 is fixedly installed on the inner side of the upper cover plate 1. Managers can directly read the instrument data through the transparent observation window 8, making it convenient to check the instrument status at any time and avoid wear caused by frequent opening of the cover plate.

[0027] The top of the transparent observation window 8 is rotatably fitted with a connecting plate 9, and the lower cover plate 2 is fixedly connected to an L-shaped sleeve plate 10 on its sides. An extension plate 11 is slidably fitted inside the L-shaped sleeve plate 10. The extension plate 11 and the connecting plate 9 are rotatably fitted together to connect the upper cover plate 1 and the lower cover plate 2 together, so as to prevent the upper cover plate 1 from being lost. At the same time, when the upper cover plate 1 and the lower cover plate 2 are put together, the distance between them can be adjusted so that the L-shaped locking teeth 3 can be smoothly inserted into the L-shaped locking slots 4.

[0028] Furthermore, the outer periphery of the upper cover plate 1 and the lower cover plate 2 are both fixedly connected with fixing holes 12. The two fixing holes 12 are symmetrically arranged. The fixing holes 12 on the upper or lower side are locked by the lock head, which plays a limiting and locking role in closing the upper cover plate 1 and the lower cover plate 2. Thus, the anti-theft instrument sealing work is completed.

[0029] A drainage groove 13 is provided through the outer periphery of the lower cover plate 2, so that the water accumulated in the cavity formed between the inner wall of the lower cover plate 2 and the second sealing ring groove 6 can be smoothly discharged with the help of the drainage groove 13, effectively avoiding water residue.

[0030] The operation process of this embodiment is as follows: When in use, first fix the lower cover plate 2 onto the instrument, then insert the sealing ring 7 into the second sealing ring groove 6, and insert each L-shaped tooth 3 on the upper cover plate 1 into the corresponding L-shaped groove 4. At this time, the upper cover plate 1 and the lower cover plate 2 are fitted together, and the two ends of the sealing ring 7 are respectively inserted into the first sealing ring groove 5 and the second sealing ring groove 6. Then rotate the upper cover plate 1 so that the L-shaped tooth 3 is inserted into the tail end of the L-shaped groove 4. At this time, the upper cover plate 1 and the lower cover plate 2 are engaged, and the sealing ring 7 also plays a sealing role, thereby preventing external dust and moisture from entering the seal through the gap between the two covers. Finally, lock the fixing hole seat 12 on the upper or lower side respectively by locking the lock head to limit and lock the upper cover plate 1 and the lower cover plate 2 to complete the anti-theft instrument sealing work.
