Description

Technical Field

[0001] This utility model relates to the field of gas leak prevention, and in particular to a quick-installation structure for a gas leak control device for an intelligent gas stove. Background Technology

[0002] Intelligent gas stoves typically use natural gas or liquefied petroleum gas (LPG). Natural gas is mainly composed of methane, while LPG is mainly composed of propane and butane. It is usually stored in steel cylinders, has a high calorific value, and is portable, but the pressure needs to be adjusted through a pressure reducing valve when in use.

[0003] The commonly used gas leak control device in smart gas stoves is the smart gas leak protector. It monitors key indicators such as pressure, flow, and temperature of the gas pipeline in real time, and automatically cuts off the gas supply when it detects gas leaks, abnormal pressure, excessive flow, or excessive temperature, thus preventing gas accidents.

[0004] Currently, existing gas leak control devices typically use flexible joints and clamps to secure themselves to gas pipes of different diameters in order to connect with them. However, to ensure a stable connection, existing pipe joints have grooves at their interfaces. But the inner and outer sides of the clamps are flat, so when connecting with clamps, the grooves of the joints may not make good contact with the flexible joints, thus affecting the fixing effect. If the grooves are to be used more effectively, multiple sealing rings need to be installed, and it is necessary to ensure that the sealing rings are in the grooves during installation. This makes the installation process difficult, time-consuming, and labor-intensive. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a quick installation structure for a gas leak control device for intelligent gas stoves. It aims to solve the problems in the existing technology where it is difficult to ensure that the recessed position of the joint is properly utilized when connecting with clamps, and the time required is too long if a sealing ring is added.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a quick installation structure for a gas leak control device for an intelligent gas stove, comprising a positioning block, the positioning block being arc-shaped, a fixing frame being fixedly connected to the outer circumferential surface of the positioning block, a covering sheet being fixedly connected to the inner wall of the positioning block, an airbag being fixedly connected to the side of the covering sheet near the inner circumferential surface of the positioning block, a winding assembly being provided inside the fixing frame, a steering auxiliary assembly being provided inside the fixing frame, and a deformation control assembly being provided together inside the fixing frame and the positioning block; The deformation control component includes a pneumatic box, the outer wall of which is through and fixedly connected to the inner wall of the positioning block and the inner wall of the fixing frame. A partition is fixedly connected to the inner wall of the pneumatic box. A piston plate is piston-connected to the inner wall of the pneumatic box on the right side of the partition. A threaded rod is rotatably connected to the upper surface of the piston plate.

[0007] As a further description of the above technical solution: the end of the airbag located inside the positioning block has a hole that communicates with the air pressure box.

[0009] As a further description of the above technical solution: the positioning block is made of rubber, and the rubber belongs to the category of soft materials, but has certain hardness characteristics.

[0010] As a further description of the above technical solution: the steering assist component includes a steering groove, and a rotating roller is rotatably connected to the inner wall of the steering groove. The rotating roller is disposed at the corner of the covering sheet.

[0011] As a further description of the above technical solution: the air pressure box has a hole on the upper surface of the right side of the partition to allow communication between the inside and outside of the air pressure box.

[0012] As a further description of the above technical solution: the material of the covering sheet is metal, and the edges of the covering sheet are rounded.

[0013] As a further description of the above technical solution: the inner wall of the positioning block is provided with a groove for the covering sheet and the airbag to pass through, and the thickness of the groove is the same as the sum of the thickness of the covering sheet and the thickness of the airbag in the non-inflated state.

[0018] 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.

[0019] Reference Figure 1 - Figure 3This utility model provides an embodiment of a quick-installation structure for a gas leak control device for an intelligent gas stove, comprising a positioning block 1. The positioning block 1 is made of rubber, which is soft but has a certain degree of hardness. The positioning block 1 ensures that it can deform and thus fit against the outer surface of the pipe. The positioning block 1 is arc-shaped, and a fixing frame 2 is fixedly connected to its outer circumference. The fixing frame 2 is arc-shaped and made of rigid material. The curvature of the inner arc surface of the fixing frame 2 is consistent with the shape of the outer circumference of the positioning block 1 when it is not deformed. A covering sheet is fixedly connected to the inner wall of the positioning block 1. 3. The material of the covering sheet 3 is metal, and the edge of the covering sheet 3 is rounded. An airbag 4 is fixedly connected to the side of the covering sheet 3 near the inner circumference of the positioning block 1. The airbag 4 is made of silicone. The inner wall of the positioning block 1 has a groove for the covering sheet 3 and the airbag 4 to pass through. The thickness of the groove is the same as the sum of the thickness of the covering sheet 3 and the thickness of the airbag 4 in the non-inflated state. By setting the same thickness, it is ensured that the airbag 4 inside the positioning block 1 cannot inflate. A metal support is set inside the groove of the positioning block 1. By setting the support, it is ensured that the airbag 4 will not inflate inside the positioning block 1 due to the deformability of the positioning block 1.

[0020] Reference Figure 3 - Figure 5 The fixed frame 2 is equipped with a winding assembly 5, which includes a winding wheel 51. The winding wheel 51 is used to wind up the covering sheet 3 and the airbag 4. The outer wall of the winding wheel 51 is rotatably connected to the inner cavity of the fixed frame 2. The inner wall of the winding wheel 51 is provided with a sliding groove 52. A control rod 53 is provided through the inner wall of the winding wheel 51. The control rod 53 is cylindrical and is coaxial with the winding wheel 51. A slider 54 is fixedly connected to the outer circumference of the control rod 53. The slider 54 is rectangular and its outer wall is slidably connected to the inner wall of the sliding groove 52. The bottom outer wall of the control rod 53 is provided with a threaded groove 55. The inner wall of the fixed frame 2 below its own inner cavity is provided with a threaded hole 56 that is the same shape as the bottom threaded groove 55 of the control rod 53. The threaded groove 55 and the threaded hole 56 ensure that the control rod 53 can achieve a stable state through the self-locking of the thread, thereby preventing the winding wheel 51 from rotating.

[0021] Reference Figure 3 - Figure 5 The fixed frame 2 is equipped with a steering auxiliary component 6. The steering auxiliary component 6 includes a steering groove 61. A rotating roller 62 is rotatably connected to the inner wall of the steering groove 61. The surface of the rotating roller 62 is smooth. The rotating roller 62 is located at the corner of the covering sheet 3. When the covering sheet 3 contacts the rotating roller 62 and is in a winding state, the covering sheet 3 can drive the rotating roller 62 to rotate during the movement, thereby reducing the friction between its movement and the fixed frame 2.

[0022] Reference Figure 3 - Figure 5 The deformation control component 7 is jointly provided inside the fixed frame 2 and the positioning block 1. The deformation control component 7 includes a pressure box 71. The pressure box 71 has an insulation layer inside to ensure that the volume of gas inside is not easily affected by the external temperature. The end of the airbag 4 inside the positioning block 1 has a hole that communicates with the pressure box 71. Through the setting of this hole, it is ensured that the gas inside the pressure box 71 can flow into the airbag 4. The outer wall of the pressure box 71 is through and fixedly connected to the inner wall of the positioning block 1 and the inner wall of the fixed frame 2. The inner wall of the pressure box 71 is fixedly connected to a partition 72. The upper surface of the pressure box 71 on the right side of the partition 72 has a hole that connects the inside and outside of the pressure box 71. The inner wall of the pressure box 71 on the right side of the partition 72 is piston-connected to a piston plate 73. The outer wall of the piston plate 73 is in contact with the inner wall of the pressure box 71 and the right surface of the partition 72. The upper surface of the piston plate 73 is rotatably connected to a threaded rod 74.

[0023] Working principle: When in use, the operator first puts the hose connected to the output end of the gas leak control device of the smart gas stove onto the outside of the joint of the pipeline used to transport gas, and then places the ring-shaped covering piece 3 on the outside of the hose.

[0024] After completing this operation, the staff rotates the control rod 53 while the positioning block 1 and the fixed frame 2 are manually fixed. This causes the control rod 53 to rotate the winding wheel 51, thereby winding up the covering sheet 3 and the airbag 4. As a result, after the covering sheet 3 is wound up, its inner wall can fit against the outer wall of the pipe and adhere tightly to the outer surface of the pipe joint.

[0025] Since the corner of the covering sheet 3 contacts the outer wall of the rotating roller 62 during the movement, the covering sheet 3 will not generate much friction when it moves.

[0026] After the initial fixing of the hose and pipe joint is completed, the worker rotates the threaded rod 74, causing the threaded rod 74 to move downward during rotation, pushing the piston plate 73 downward. This allows the gas inside the pressure box 71 to enter the air bladder 4 under pressure. Since the two ends of the air bladder 4 between the protruding positions of the hose and pipe joint are compressed, there is no room for deformation. Therefore, only the air bladder 4 between the concave positions of the hose and pipe joint will expand. When it expands, it can occupy the concave position of the joint, thus ensuring the stability of the connection.

[0027] 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.
