Description

Technical Field

[0001] This utility model relates to the field of gas meter technology, specifically a gas metering device. Background Technology

[0002] Gas meters are devices used to measure and record gas consumption. They are widely used in homes, industries, and businesses to measure and monitor the supply and consumption of gas.

[0003] Currently, gas meters are generally directly connected to the inlet and outlet pipes, forming a support for their suspended installation. To ensure stability, they are typically fixed to the wall with screws. Since these meters are exposed, dust accumulates on the display screen and mounting slots over time, making cleaning difficult and potentially damaging the meter. Furthermore, the bolted mounting method requires maintenance, necessitating individual screw unscrewing to remove the meter, which is inconvenient and can damage the wall. Therefore, we propose a new type of gas meter. Utility Model Content

[0004] In view of the shortcomings of the prior art mentioned in the background section, this utility model provides a gas meter.

[0005] This utility model overcomes the above technical problems by adopting the following technical solution:

[0006] A gas meter includes: a meter body and a positioning component. A protective mechanism is connected to the front of the meter body, and two locking mechanisms are provided on the protective mechanism. A fixing mechanism is provided on the back of the meter body, and two blocking mechanisms are provided on the fixing mechanism. The positioning component is movably connected to the two fixing mechanisms.

[0007] As a further embodiment of this utility model: the protective mechanism includes two hollow frames, two vertical rods, two sliders, two first springs, and a transparent cover. The two hollow frames are connected to the front of the watch body. The two vertical rods are respectively connected between the top and bottom of the inner wall of the two hollow frames. The two sliders are respectively slidably connected to the outer surface of the two vertical rods, and slots are provided on the opposite sides of the two sliders. The two first springs are respectively connected to the top of the two sliders, and one end of the two first springs is respectively connected to the top of the inner wall of the two hollow frames. The transparent cover is connected between the two sliders.

[0008] As a further embodiment of this utility model: the locking mechanism includes a slide rod, a handle, a second spring, and a telescopic rod. Both telescopic rods are connected to one side of one of the hollow frames. The handle is connected to one end of the two telescopic rods. The slide rod is slidably connected to one side of one of the hollow frames. The other end of the slide rod is connected to one side of the handle. The second spring is connected between one side of one of the hollow frames and one side of the handle.

[0009] As a further embodiment of this utility model: one end of the slide rod is movably inserted into the interior of one of the slots, and the two first springs and the second spring are respectively located outside the two vertical rods and the slide rod.

[0010] As a further embodiment of this utility model: the fixing mechanism includes a limiting frame, a bidirectional threaded rod, a throttle, two L-shaped plates, and two positioning blocks. The limiting frame is connected to the back of the watch body. The bidirectional threaded rod is rotatably connected between the two sides of the inner wall of the limiting frame, and one end of the bidirectional threaded rod extends to one side of the limiting frame. The throttle is connected to one end of the bidirectional threaded rod. Both L-shaped plates are threaded to the outer surface of the bidirectional threaded rod, and both L-shaped plates extend to the back of the limiting frame. The two positioning blocks are respectively connected to the adjacent sides of the two L-shaped plates.

[0011] As a further embodiment of this utility model: the positioning component includes a fixing plate and two limiting grooves. The fixing plate is attached to the back of the limiting frame, and the two limiting grooves are respectively opened on both sides of the fixing plate, and the two positioning blocks are adapted to the interior of the two limiting grooves.

[0012] As a further embodiment of this utility model: the blocking mechanism includes a hollow plate and a baffle. The hollow plate is connected to one side of the back of the limiting frame, and the baffle is slidably connected inside the hollow plate, with one end of the baffle connected to one side of one of the L-shaped plates.

[0013] By adopting the above structure, this utility model has the following advantages compared with the prior art:

[0014] 1. In this utility model, through the action of the protective mechanism and two locking mechanisms, not only can the front of the watch body be protected from dust, preventing dust from falling into the slot and on the surface of the display screen, but the protective mechanism can also be easily opened when needed and quickly restored to the protective state after use. The operation process is convenient, which can protect the components on the front of the watch body without affecting the normal use of the watch body, thereby improving the practicality of the watch body.

[0015] 2. In this utility model, with the help of the positioning component and the fixing mechanism, the meter body can be conveniently and quickly connected to the positioning component after the positioning component is installed on the wall. Compared with the traditional method of fixing the meter body to the wall, the wall will not be damaged when disassembling each time. Moreover, the installation and fixing method is convenient and firm, further improving the practicality of the meter body. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please see Figures 1-6In this embodiment of the utility model, a gas meter includes: a meter body 1 and a positioning component 4. A protective mechanism 2 is connected to the front of the meter body 1, and two locking mechanisms 3 are provided on the protective mechanism 2. A fixing mechanism 5 is provided on the back of the meter body 1, and two blocking mechanisms 6 are provided on the fixing mechanism 5. The positioning component 4 is movably connected to the two fixing mechanisms 5.

[0026] Specifically, pulling the two locking mechanisms 3 and pushing the protective mechanism 2 upward will stretch the protective mechanism 2. Releasing the two locking mechanisms 3 will reset the protective mechanism 2 and lock it in place, fixing the current position of the protective mechanism 2 so that it no longer obstructs the front of the meter body 1. Pulling the two locking mechanisms 3 again will release the lock on the protective mechanism 2, at which point the protective mechanism 2 will reset and descend from the front of the meter body 1, thus obstructing the front of the meter body 1 and completing the dust protection for the front of the meter body 1. After fixing the positioning component 4 to the wall with screws, attach the fixing mechanism 5 on the back of the meter body 1 to the positioning component 4. Then rotate the fixing mechanism 5 to insert and fix it to the positioning component 4, thus fixing the meter body 1 to the positioning component 4. The two obstructing mechanisms 6 can provide dust protection for the fixing mechanism 5.

[0027] Example 2:

[0028] Please see Figures 1-4 In this embodiment of the utility model, a gas metering device includes a protective mechanism 2 comprising two hollow frames 201, two vertical rods 202, two sliders 203, two first springs 204, and a transparent cover 205. The two hollow frames 201 are connected to the front of the meter body 1. The two vertical rods 202 are respectively connected between the top and bottom of the inner walls of the two hollow frames 201. The two sliders 203 are slidably connected to the outer surfaces of the two vertical rods 202, and slots are provided on the opposite sides of the two sliders 203. The two first springs 204 are respectively connected to the tops of the two sliders 203, and one end of each first spring 204 is connected to the top of the inner wall of the two hollow frames 201. The transparent cover 205 is connected to... Between the two sliders 203, the locking mechanism 3 includes a slide rod 301, a handle 302, a second spring 303, and a telescopic rod 304. Both telescopic rods 304 are connected to one side of one of the hollow frames 201. The handle 302 is connected to one end of the two telescopic rods 304. The slide rod 301 is slidably connected to one side of one of the hollow frames 201. The other end of the slide rod 301 is connected to one side of the handle 302. The second spring 303 is connected between one side of one of the hollow frames 201 and one side of the handle 302. One end of the slide rod 301 is movably inserted into the interior of one of the slots. The two first springs 204 and the second spring 303 are located outside the two vertical rods 202 and the slide rod 301, respectively.

[0029] Specifically, pulling handle 302 causes slide bar 301 to slide outward from inside one of the hollow frames 201 and retract from the interior of one of the hollow frames 201. Simultaneously, the two telescopic rods 304 and the second spring 303 extend and stretch, pulling the transparent cover 205 upward, causing the two sliders 203 to slide upward on the outer surface of the two vertical rods 202, compressing the two first springs 204. After the two sliders 203 have slid a certain distance, releasing handle 302 causes the second spring 303 to return to its original position, causing slide bar 301 to retract. Slide it back into one of the hollow frames 201 and insert it into one of the slots to fix the position of one of the sliders 203. At this time, the transparent cover 205 will no longer block the front of the watch body 1. Pull the handle 302 to drive the slide bar 301 out of one of the slots and release the lock on one of the sliders 203. The two first springs 204 will reset and drive the two sliders 203 to slide down, so that the transparent cover 205 covers the front of the watch body 1, completing the dust protection of the front of the watch body 1.

[0030] Example 3:

[0031] Please see Figures 1-6 In this embodiment of the utility model, a gas metering device includes a fixing mechanism 5 comprising a limiting frame 501, a bidirectional threaded rod 502, a throttle 503, two L-shaped plates 504, and two positioning blocks 505. The limiting frame 501 is connected to the back of the meter body 1. The bidirectional threaded rod 502 is rotatably connected between the two sides of the inner wall of the limiting frame 501, with one end of the bidirectional threaded rod 502 extending to one side of the limiting frame 501. The throttle 503 is connected to one end of the bidirectional threaded rod 502. Both L-shaped plates 504 are threadedly connected to the outer surface of the bidirectional threaded rod 502, and both L-shaped plates 504 extend to the back of the limiting frame 501. On the side, two positioning blocks 505 are respectively connected to the adjacent sides of two L-shaped plates 504. The positioning component 4 includes a fixing plate 401 and two limiting grooves 402. The fixing plate 401 is attached to the back of the limiting frame 501. The two limiting grooves 402 are respectively opened on both sides of the fixing plate 401, and the two positioning blocks 505 are adapted to the interior of the two limiting grooves 402. The blocking mechanism 6 includes a hollow plate 601 and a baffle 602. The hollow plate 601 is connected to one side of the back of the limiting frame 501. The baffle 602 is slidably connected to the interior of the hollow plate 601, and one end of the baffle 602 is connected to one side of one of the L-shaped plates 504.

[0032] Specifically, the fixing plate 401 is fixed to the wall using four fixing holes and four screws. The limiting bracket 501 on the back of the meter body 1 is then aligned with the front of the fixing plate 401. Rotating the handle 503 causes the bidirectional threaded rod 502 to rotate, causing the two L-shaped plates 504 to move towards each other and drive the two positioning blocks 505 to insert into the two limiting slots 402. This completes the fixing of the meter body 1 onto the fixing plate 401. At the same time, the movement of the L-shaped plates 504 causes the baffle 602 to slide outward inside the hollow plate 601, which can continuously shield the back of the limiting bracket 501, thereby preventing dust from entering the interior of the limiting bracket 501.

[0033] The working principle of this utility model is as follows: The transparent cover 205 shields the slot and display screen on the front of the watch body 1, providing dust protection. When needed, simply pull the handle 302. The handle 302 causes the sliding rod 301 to slide outward inside one of the hollow frames 201, thereby extending the two telescopic rods 304. Simultaneously, the second spring 303 is stretched, and one end of the second spring 303 retracts from the interior of one of the hollow frames 201. Then, pull the transparent cover 205 upward. 5. The two sliders 203 slide upwards on the outer surface of the two vertical rods 202, thereby compressing the two first springs 204. After the two sliders 203 have slid a certain distance, the handle 302 is released, and the second spring 303 will return to its original position, causing the slide rod 301 to slide back into the interior of one of the hollow frames 201 and into the interior of one of the slots, fixing the position of one of the sliders 203. At this time, the transparent cover 205 will no longer obstruct the front of the watch body 1, and the watch body 1 can be used. When not in use, simply... Pulling handle 302 will cause slide bar 301 to retract from one of the slots, releasing the lock on one of the sliders 203. At this time, the two first springs 204 will reset, causing the two sliders 203 to slide down, so that the transparent cover 205 covers the front of the watch body 1, thus protecting the front of the watch body 1. When it is necessary to easily fix and disassemble the watch body 1, first fix the fixing plate 401 to the wall through the four fixing holes and four screws, and then align the limiting bracket 501 on the watch body 1 with the front of the fixing plate 401. Rotating the handle 503 causes the bidirectional threaded rod 502 to rotate inside the limiting frame 501, thereby causing the two L-shaped plates 504 to move towards each other, so that the two positioning blocks 505 are inserted into the two limiting slots 402, thus completing the connection between the meter body 1 and the fixing plate 401, thereby completing the fixed installation of the meter body 1. As the L-shaped plate 504 moves, it will cause the baffle 602 to slide outward inside the hollow plate 601, which can shield the back of the limiting frame 501 and prevent dust from entering the interior of the limiting frame 501.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
