Description

Technical Field

[0001] This utility model relates to the field of gas meter connector technology, and in particular to a gas meter connector that connects to the gas outlet connector of a gas meter. Background Technology

[0002] In residential homes, the gas meter connector connects the gas meter to the home's internal gas pipeline system, ensuring that the gas measured by the gas meter can be safely and stably delivered to various gas appliances, such as gas stoves, gas water heaters, and gas wall-hung boilers, to meet the family's needs for cooking, hot water supply, and heating.

[0003] In existing technologies, some gas meter connectors ensure safe gas transmission through multiple sealing and secure connections. The connector's internal structure includes a rubber sealing ring that fits tightly against the gas meter's outlet connector, filling gaps through compression deformation to prevent gas leakage. Externally, it uses threaded or snap-fit ​​connections to screw or snap onto the outlet connector, ensuring a secure connection.

[0004] However, during actual use, leaked gas can cause corrosion and damage to surrounding equipment and pipelines. For example, long-term corrosion of metal pipelines by gas can accelerate pipeline aging and damage, shorten their service life, and require early replacement, increasing the cost of equipment maintenance and replacement. In response to the above problems, a gas meter connector that connects to the gas meter outlet connector is proposed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a gas meter connector that connects to the gas meter outlet connector, aiming to improve the problem that some gas meter connectors in the prior art cannot prevent leakage of the gas outlet pipe.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A gas meter connector for connection to a gas meter outlet includes a mounting base. A connecting seat is fixedly connected to the top of the mounting base, and a connecting pipe is fixedly connected to the top of the connecting seat. Multiple gas outlet pipes are fixedly connected to the outer right side of the connecting pipe. A mounting nut is threadedly connected to the outer side of the gas outlet pipe, and a threaded sleeve is fixedly connected to the outer side of the gas outlet pipe. An anti-leakage mechanism is rotatably connected to the outer side of the mounting nut. Disassembly and assembly mechanisms are slidably connected to both the front and rear sides of the top of the mounting base.

[0008] The leak-proof mechanism includes a threaded ring, the outer thread of which is connected to the outside of the threaded sleeve. A leak-proof housing is fixedly connected inside the threaded ring. A vent hole is provided on the outer left side of the leak-proof housing. An installation tube is fixedly connected inside the leak-proof housing. A reset component is slidably connected to the outside of the installation tube. Both the upper and lower ends of the outside of the installation tube are slidably connected to locking blocks. A rubber sealing tube is fixedly connected inside the installation tube.

[0009] As a further description of the above technical solution:

[0010] The reset assembly includes a grooved slip ring, the inside of which is slidably connected to the outside of the mounting tube, and a reset spring is sleeved on the outside of the mounting tube;

[0011] As a further description of the above technical solution:

[0012] The outer groove of the grooved slip ring contacts the outer side of the locking block, and the outer side of the locking block is locked to the outer side of the rubber sealing tube;

[0013] As a further description of the above technical solution:

[0014] The disassembly and assembly mechanism includes a sliding latch rod, which is externally slidably connected to the front and rear sides of the mounting chassis. The mounting chassis has a cavity inside, and a limit plate is slidably connected inside the cavity.

[0015] As a further description of the above technical solution:

[0016] A tension spring is sleeved on the outside of the sliding lever, and a connecting nut is threaded to the bottom of the outer side of the sliding lever;

[0017] As a further description of the above technical solution:

[0018] A filter screen is fixedly connected to the outside of the sliding lever, and the outside of the connecting nut is in contact with the bottom of the filter screen.

[0019] As a further description of the above technical solution:

[0020] The limiting plate is fixedly connected to the outside of the sliding rod, and the outside of the sliding rod is slidably connected to the inside of the cavity;

[0021] As a further description of the above technical solution:

[0022] One end of the return spring is fixedly connected to the outside right side of the grooved slip ring, and the other end of the return spring is fixedly connected to the inside of the leak-proof housing.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, when the gas is being transported, the gas enters the interior of the leak-proof housing through the vent hole, which in turn allows the gas pressure to squeeze the grooved slip ring, which in turn squeezes the return spring, causing the return spring to deform. This allows the grooved slip ring to slide outside the mounting tube. When it slides to the outside of the locking block, the force of the gas causes the locking block to fit into the groove inside the grooved slip ring, allowing the gas to be discharged through the rubber sealing tube.

[0025] 2. In this utility model, the sliding lever drives the limiting plate to slide inside the cavity, which in turn allows the limiting plate to compress the tension spring, thereby separating the sliding lever from the filter screen and allowing the filter screen to be removed. When installing the filter screen, by releasing the sliding lever, the tension spring rebounds, which then locks the sliding lever into place with the filter screen. At this point, by rotating the connecting nut, the connecting nut and the sliding lever are tightly fitted together, thus enabling the installation of the filter screen. Attached Figure Description

Detailed Implementation

[0033] 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.

[0034] Reference Figures 1 to 3 This utility model provides an embodiment of a gas meter connector for connection to the gas meter outlet. The connector includes a mounting base 1, which secures the gas meter connector in a suitable location on the gas equipment, ensuring stability and reliability during use. A connecting seat 2 is fixedly connected to the top of the mounting base 1. The connecting seat 2 has a specific groove designed inside, which tightly fits with the end of a connecting pipe 3. A threaded connection or other method ensures a tight connection and prevents gas leakage. A connecting pipe 3 is fixedly connected to the top of the connecting seat 2. The connecting pipe 3 is the main channel for gas flow, and its diameter is precisely designed according to the required gas flow rate. Its smooth internal surface reduces resistance to gas flow. To ensure the smooth flow of gas, multiple gas outlet pipes 4 are fixedly connected to the outer right side of the connecting pipe 3. The gas outlet pipes 4 are key components for diverting gas to various gas-using devices. They have good flexibility and pressure resistance. The diameter of each gas outlet pipe 4 is reasonably configured according to the gas demand of the connected gas-using device to ensure that each gas-using device can obtain a stable gas supply. The external thread of the gas outlet pipe 4 is connected to the mounting nut 5. The function of the mounting nut 5 is to tightly fix the gas outlet pipe 4 to the connecting parts of the gas-using device. By rotating the mounting nut 5, it engages with the thread on the gas outlet pipe 4, and the end of the gas outlet pipe 4 is tightly pressed with the interface of the gas-using device to form a reliable sealing connection.

[0035] The external fixed connection of the gas outlet pipe 4 is a threaded sleeve 6. The function of the threaded sleeve 6 is to provide a reliable threaded connection base for the mounting nut 5, and to enhance the connection strength and stability between the mounting nut 5 and the gas outlet pipe 4. The external rotating connection of the mounting nut 5 is a leak-proof mechanism. The top front and rear sides of the mounting chassis 1 are slidably connected to the disassembly and assembly mechanism. The disassembly and assembly mechanism includes a sliding clamp 15. The main function of the sliding clamp 15 is to provide a convenient fixing and disassembly method when installing and disassembling the gas meter connector. By sliding the sliding clamp 15, the gas meter connector can be quickly engaged or disassembled with the mounting bracket or fixed parts of the gas equipment, which greatly improves the efficiency of installation and disassembly. The external sliding connection of the sliding clamp 15 is on the front and rear sides of the mounting chassis 1.

[0036] The mounting chassis 1 has an internal cavity 18. The inner wall of the cavity 18 is smoothed to reduce the frictional resistance of the internal components during movement, thereby improving the service life and working efficiency of the disassembly and assembly mechanism. A limit plate 19 is slidably connected inside the cavity 18. The main function of the limit plate 19 is to limit the sliding range of the sliding lever 15, preventing the sliding lever 15 from detaching from the mounting chassis 1 or exceeding the normal working range during sliding. A tension spring 20 is sleeved on the outside of the sliding lever 15. The function of the tension spring 20 is to provide the reset power for the sliding lever 15. When the sliding lever 15 is pulled outward for disassembly, the tension spring 20 can automatically pull the sliding lever 15 back to its original position, achieving quick reset. A connecting nut 17 is threaded to the bottom of the sliding lever 15. By rotating the connecting nut 17, the preload of the tension spring 20 can be adjusted to adapt to different installation and usage requirements.

[0037] The leak-proof mechanism includes a threaded ring 7. By rotating the threaded ring 7, a stable connection between the leak-proof mechanism and the gas outlet pipe 4 can be achieved. The external thread of the threaded ring 7 is connected to the outside of the threaded sleeve 6. The internal thread of the threaded ring 7 is fixedly connected to the leak-proof housing 8. The inner wall of the leak-proof housing 8 is specially treated, with a smooth and flat surface, which reduces the resistance when the gas flows inside and also facilitates the installation and maintenance of internal components. A vent hole 9 is opened on the left side of the external leak-proof housing 8. The internal installation pipe 10 is fixedly connected to the internal installation pipe 8. The installation pipe 10 serves as the installation carrier for the reset assembly and the rubber sealing pipe 14, and has good rigidity and stability. The external installation pipe 10 is slidably connected to the reset assembly, which includes a grooved slip ring 11. The main function of the grooved slip ring 11 is to drive the locking block 13 to reciprocate under the action of the reset spring 12, thereby squeezing and releasing the rubber sealing pipe 14 and controlling the sealing state of the rubber sealing pipe 14. The internal grooved slip ring 11 is slidably connected to the external installation pipe 10, and the external installation pipe 10 is fitted with a reset spring 12.

[0038] The main function of the return spring 12 is to provide the return force for the grooved slip ring 11 and the locking block 13. When the gas meter connector is connected to the gas-using equipment, the gas pushes the locking block 13 and the grooved slip ring 11 to compress the return spring 12, so that the rubber sealing tube 14 is in a loose state, ensuring that the gas can pass smoothly. The upper and lower ends of the installation tube 10 are slidably connected to the locking block 13. Under the drive of the grooved slip ring 11, the locking block 13 slides up and down on the outside of the installation tube 10. One end of the locking block 13 is designed as a bevel or arc shape, so that it can be pushed open smoothly when connected to the gas-using equipment. The other end contacts the rubber sealing tube 14. By squeezing and releasing the rubber sealing tube 14, the function of sealing and gas passage is switched. The rubber sealing tube 14 is fixedly connected inside the installation tube 10. The main function of the rubber sealing tube 14 is to undergo elastic deformation under the squeezing of the locking block 13, and tightly fit against the inner wall of the gas outlet tube 4 to form a reliable seal and prevent gas leakage. When the locking block 13 is released, the rubber sealing tube 14 returns to its original state, forming a gas flow channel inside to ensure that the gas can be delivered to the gas-using equipment normally.

[0039] Reference Figures 3 to 5 The outer groove of the grooved slip ring 11 contacts the outer side of the locking block 13. The outer side of the locking block 13 is locked to the outer side of the rubber sealing tube 14. The outer side of the sliding rod 15 is fixedly connected to a filter screen 16. The filter screen 16 can effectively intercept particulate impurities in the gas. Its surface is electrolytically polished to reduce the problem of increased pressure drop caused by impurity adhesion. The outer side of the connecting nut 17 contacts the outer bottom of the filter screen 16. The inner side of the limiting plate 19 is fixedly connected to the outer side of the sliding rod 15. The outer side of the sliding rod 15 is slidably connected to the inside of the cavity 18. Rubber dustproof rings are designed at both ends of the cavity 18 to effectively prevent dust and moisture from entering the cavity 18 and extend the service life of the sliding rod 15. One end of the return spring 12 is fixedly connected to the outer right side of the grooved slip ring 11, and the other end of the return spring 12 is fixedly connected to the inside of the leak-proof housing 8.

[0040] Working principle: When gas is being transported, it enters the interior of the leak-proof housing 8 through the vent 9, which in turn compresses the grooved slip ring 11, causing it to compress the return spring 12. This causes the return spring 12 to deform, allowing the grooved slip ring 11 to slide outside the mounting tube 10. When it slides to the outside of the locking block 13, the force of the gas causes the locking block 13 to engage with the groove inside the grooved slip ring 11, allowing the gas to be discharged through the rubber sealing tube 14. When the gas supply stops, the return spring 12 rebounds, pushing the grooved slip ring 11 away from the locking block 13. This allows the locking block 13 to engage with the rubber sealing tube 14, preventing gas leakage from the rubber sealing tube 14.

[0041] When disassembling and assembling the filter screen 16, the connecting nut 17 is rotated to separate it from the sliding lever 15. Then, by pulling the sliding lever 15, the limiting plate 19 slides within the cavity 18, causing the limiting plate 19 to press against the tension spring 20. This separates the sliding lever 15 from the filter screen 16, allowing the filter screen 16 to be removed. When installing the filter screen 16, the tension spring 20 is released, causing the sliding lever 15 to snap into place with the filter screen 16. Rotating the connecting nut 17 then ensures a tight fit between the connecting nut 17 and the sliding lever 15, enabling the filter screen 16 to be installed.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
