Description

Technical Field

[0001] The present application relates to the technical field of natural gas equipment, and more specifically, to an automatic natural gas meter that is easy to maintain. Background Art

[0002] Natural gas is a clean, environmentally friendly, high-quality energy source that contains almost no sulfur, dust, or other harmful substances. When burned, it produces less carbon dioxide than other fossil fuels, resulting in a lower greenhouse effect, which can fundamentally improve environmental quality. A natural gas meter is a measuring instrument used to measure natural gas consumption. Its function is to convert natural gas consumption into a standard volume for easy measurement and settlement. In order to improve the safety and service life of natural gas meters in household users, a protective cabinet will be installed on the outside of the natural gas meter. The patent document with the prior art announcement number CN218330111U provides an automated natural gas meter that is easy to maintain. The device is arranged by the cooperation of a slide rail, a fixed block, a buckle, a slider, and a block. The natural gas meter body is fixed by the clamping of the slide rail and the slider, the buckle, and the block, so that maintenance personnel can disassemble and repair the natural gas meter.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the device only fixes the bottom of the meter by the cooperation between the buckle and the block, and the fixing range is small and the stability is poor. Therefore, we propose an automatic natural gas meter that is easy to maintain. Utility Model Content

[0004] In order to improve the problems raised in the above background technology, the present application provides an automatic natural gas meter that is easy to maintain, and adopts the following technical solutions:

[0005] An automated natural gas meter that is easy to maintain comprises a natural gas meter main body and a protective box arranged outside the natural gas meter main body, wherein a box door is hinged on one side of the protective box, and fixed frames are fixedly connected on both symmetrical sides of the protective box, and two clamping plates are slidably connected to the fixed frames, and a wedge block A is slidably connected to the fixed frames, and a support rod is hinged between the wedge block A and the box door, and a wedge block B is arranged on one side of the wedge block A, and when the wedge block A abuts against the wedge block B, the clamping plates are driven to clamp and fix the natural gas meter main body.

[0006] By adopting the above technical solution, after the natural gas meter body is placed in the protective box, when the box door is closed, the support rod drives the wedge block A to slide downward, and the wedge block A abuts against the wedge block B, so that the clamping plate moves toward one side of the natural gas meter body, and the clamping plates on both sides cooperate to clamp and fix the corners of the natural gas meter body.

[0007] Optionally, an observation window is installed on the box door.

[0008] By adopting the above technical solution, the data inside the main body of the natural gas meter can be observed through the observation window when the box door is closed.

[0009] Optionally, a connecting plate is fixedly connected to the wedge block B, both ends of the connecting plate are connected and fixed to two clamping plates, and both ends of the connecting plate are elastically connected to the fixing frame through a spring A.

[0010] By adopting the above technical solution, when the inclined surface of wedge block A abuts against the inclined surface of wedge block B, wedge block B drives the connecting plate to move toward the side of the natural gas meter body, so that the clamping plate clamps the natural gas meter body. At the same time, spring A is stretched, and when wedge block A does not abut against wedge block B, spring A drives the clamping plate to cancel the abutment against the natural gas meter body, thereby facilitating the removal of the natural gas meter body.

[0011] Optionally, a spring B is sleeved on the fixing frame, and two ends of the spring B are respectively connected and fixed to the wedge block A and the fixing frame.

[0012] By adopting the above technical solution, the reset of the spring B can drive the wedge block A to rise, and the support rod can drive the box door to automatically rotate and open.

[0013] Optionally, the upper end of the box door is hinged to the protection box, and handles are rotatably connected to both sides of the lower end of the box door. A locking rod is fixedly connected to the handle, and a locking block is snap-fitted to the locking rod, and the locking block is fixedly connected to the inner wall of the protection box.

[0014] By adopting the above technical solution, when the box door and the protective box are closed, turning the handle can drive the locking rod and the locking block to plug in, thereby improving the connection stability between the box door and the protective box.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] 1. When the box door is closed, the support rod drives the wedge block A to descend, and the wedge block A abuts against the wedge block B to move the clamping plate toward the side of the natural gas meter body. Multiple clamping plates cooperate to abut and limit the corners of the natural gas meter body, which is simple to operate and has a good limiting effect.

[0017] 2. When spring B is fully reset and drives wedge block A to rise, the support rod drives the box door to open automatically. At this time, wedge block A is still in contact with wedge block B. By manually driving the box door to continue to rotate upward, wedge block A will not be in contact with wedge block B, thereby avoiding the cancellation of the clamping plate on the main body of the natural gas meter when the box door is opened by mistake.

[0022] The present application is further described in detail below in conjunction with the accompanying drawings.

[0023] Reference Figure 1-3 The present application includes a natural gas meter body 1, and also includes a protection box 2 arranged on the outside of the natural gas meter body 1. A box door 3 is hinged on one side of the protection box 2. A fixing frame 5 is fixedly connected on both symmetrical sides of the protection box 2. Two clamping plates 6 are slidably connected to the fixing frame 5. A wedge block A7 is slidably connected to the fixing frame 5. A support rod 8 is hinged between the wedge block A7 and the box door 3. A wedge block B9 is provided on one side of the wedge block A7. When the wedge block A7 abuts against the wedge block B9, the clamping plate 6 is driven to clamp and fix the natural gas meter body 1. After the natural gas meter body 1 is placed in the protection box 2, when the box door 3 is closed, the support rod 8 drives the wedge block A7 to slide downward, and the wedge block A7 abuts against the wedge block B9, so that the clamping plate 6 moves toward one side of the natural gas meter body 1, and the clamping plates 6 on both sides cooperate to clamp and fix the corners of the natural gas meter body 1.

[0024] Reference Figure 1 An observation window 4 is installed on the box door 3, and the data in the natural gas meter body 1 can be observed through the observation window 4 when the box door 3 is closed.

[0025] Reference Figure 1 A through hole matching the gas inlet and outlet pipes of the natural gas meter body 1 is opened on the upper side of the protection box 2, so that the external pipeline can pass through the through hole and connect with the gas inlet and outlet pipes of the natural gas meter body 1.

[0026] Reference Figure 2A connecting plate 10 is fixedly connected to the wedge block B9, and both ends of the connecting plate 10 are connected and fixed to two clamping plates 6, and both ends of the connecting plate 10 are elastically connected to the fixing frame 5 through the spring A11. When the inclined surface of the wedge block A7 abuts against the inclined surface of the wedge block B9, the wedge block B9 drives the connecting plate 10 to move to the side of the natural gas meter body 1, so that the clamping plate 6 clamps the natural gas meter body 1. At the same time, the spring A11 is stretched. When the wedge block A7 does not abut against the wedge block B9, the spring A11 drives the clamping plate 6 to cancel the abutment against the natural gas meter body 1, so as to facilitate the removal of the natural gas meter body 1.

[0027] Reference Figure 2 A spring B12 is sleeved on the fixing frame 5, and the two ends of the spring B12 are respectively connected and fixed to the wedge block A7 and the fixing frame 5. When the box door 3 is closed, the spring B12 is in a compressed and force-accumulating state. The reset of the spring B12 can drive the wedge block A7 to rise, and can drive the box door 3 to automatically rotate and open through the support rod 8.

[0028] Reference Figure 1 , Figure 2 When the spring B12 is fully reset, the support rod 8 drives the box door 3 to rotate to a horizontal state. At this time, the wedge block A7 is still in contact with the wedge block B9. When the box door 3 is manually driven to rotate upward, the contact between the wedge block A7 and the wedge block B9 can be cancelled.

[0029] Reference Figure 1 , Figure 3 The upper end of the box door 3 is hinged with the protection box 2, and handles 13 are rotatably connected on both sides of the lower end of the box door 3. A locking rod 14 is fixedly connected to the handle 13, and a locking block 15 is snap-fitted on the locking rod 14. The locking block 15 is fixedly connected to the inner wall of the protection box 2. When the box door 3 and the protection box 2 are closed, rotating the handle 13 can drive the locking rod 14 to plug into the locking block 15, thereby improving the connection stability between the box door 3 and the protection box 2.

[0030] The implementation principle of an automatic natural gas meter that is easy to maintain in an embodiment of the present application is as follows: after fixing the protective box 2 to the wall, the natural gas meter body 1 is placed in the protective box 2, and when the box door 3 is turned downward, the support rod 8 drives the wedge block A7 to slide downward, the wedge block A7 abuts against the wedge block B9, and the connecting plate 10 drives the clamping plate 6 to move to one side of the natural gas meter body 1, and the clamping plates 6 on both sides cooperate to clamp and limit the corners of the natural gas meter body 1. When the box door 3 and the protective box 2 are closed, the rotating handle 13 can drive the locking rod 14 to plug into the locking block 15 to limit the rotation of the box door 3.
