Description

Technical Field

[0001] The utility model relates to the technical field of pipeline fixing devices, in particular to a pipeline fixing device for gas installation. Background Art

[0002] The main function of a gas pipeline fixing device is to fix the gas pipeline, prevent the pipeline from moving or deforming due to factors such as gravity and temperature changes, thereby avoiding excessive pressure or bending of the pipeline, reducing safety risks. At the same time, the gas pipeline fixing device can support the pipeline, prevent the pipeline from sagging or breaking, and ensure the normal operation of the pipeline.

[0003] Existing gas pipelines are usually fixed to the wall through fixing clips. Using the fixing clips can ensure that the position of the pipeline does not move or shake. When encountering a ninety-degree angle between two walls, a ninety-degree elbow joint needs to be externally connected to the gas pipeline. When the gas passes through the elbow joint, the conveying direction of the gas is forced to change, which will impact the elbow joint and cause vibration. The vibration may cause fatigue or damage to the pipeline. The existing fixing clips can only fix and clamp straight gas pipelines, and cannot bend to fix the bent part of the gas pipeline. As a result, during the long-term conveying process of the bent part of the gas pipeline, due to the lack of supporting force, the pipeline is fatigued by vibration, and there are potential safety hazards. Therefore, a pipeline fixing device for gas installation is proposed. Summary of the Utility Model

[0026] Embodiment

[0027] Referring to Figures 1-4 , for an embodiment of the present utility model, there is provided a pipeline fixing device for gas installation, including: a fixing unit 100 and a deflection unit 200;

[0028] Among them, the fixing unit 100 includes two mounting plates 101 rotatably connected to each other. On one side of each of the two mounting plates 101, a pair of movable plates 102 are slidably arranged. On one side of each of the two mounting plates 101, a fixed block 103 is fixedly connected. On the top of each of the two fixed blocks 103, a left - and - right - hand screw rod 104 penetrating through the movable plate 102 is rotatably connected. The two left - and - right - hand screw rods 104 are respectively threadedly connected to the two pairs of movable plates 102. On one side of each movable plate 102, a fixed clamp 105 is fixedly connected. On one side of each movable plate 102, a movable clamp 106 is slidably arranged. On one side of each movable clamp 106, an adjusting rod 107 is threadedly penetrated through, and the end of each adjusting rod 107 is rotatably connected to the corresponding fixed clamp 105;

[0029] The deflection unit 200 includes a T - shaped rod 201 fixedly connected to one of the mounting plates 101. On the top of each of the two mounting plates 101, two meshing gears 202 are rotatably connected. On the top of one of the gears 202, a turning handle is fixedly connected. On the T - shaped rod 201, a toothed plate 203 is slidably arranged, and the toothed plate 203 meshes with the teeth of one of the gears 202. On the top of the toothed plate 203, a threaded rod 204 is threadedly penetrated through, and the bottom end of the threaded rod 204 is rotatably connected to the top of one of the mounting plates 101.

[0030] On one side of each of the two mounting plates 101, two mounting holes are provided. The mounting plates 101 can be fixed to the wall by fixing components such as bolts and expansion bolts. When it is necessary to fix the bent part of the gas pipeline, the threaded rod 204 is rotated so that the toothed plate 203 rises along the T-shaped rod 201. When the teeth of the toothed plate 203 no longer mesh with the teeth of the gear 202, the turning handle at the top of the gear 202 is rotated, so that the two gears 202 drive the two mounting plates 101 to deflect relative to each other. The two rotated mounting plates 101 can be perpendicular to each other at 90 degrees and fit the angle between the two walls. Then, the threaded rod 204 is rotated in the reverse direction so that the toothed plate 203 descends along the T-shaped rod 201. When the teeth of the toothed plate 203 mesh with the teeth of the gear 202, the angle between the two mounting plates 101 is fixed;

[0031] On each mounting plate 101, two movable plates 102 are symmetrically and slidably arranged. The two movable plates 102 are respectively threadedly connected to two threads in different directions of the left-hand and right-hand lead screw 104. First, one of the mounting plates 101 is used to clamp and fix the gas pipeline. When the left-hand and right-hand lead screw 104 is rotated, the two movable plates 102 on the mounting plate 101 can approach each other, so that the fixed clamp 105 and the movable clamp 106 can clamp and fix gas pipelines with different diameters. Then, the two fixed clamps 105 between the opposite surfaces of the two movable plates 102 initially clamp the gas pipeline. The ends of the fixed clamp 105 and the movable clamp 106 are both arc-shaped;

[0032] When the gas pipeline fits the inner walls of the two fixed clamps 105, the adjusting rods 107 of the two corresponding movable clamps 106 are rotated, so that the two movable clamps 106 move along the two movable plates 102 respectively, and the interval between the fixed clamp 105 and the corresponding movable clamp 106 is shortened. The gas pipeline can be clamped and fixed by the two fixed clamps 105 and the two movable clamps 106. After one mounting plate 101 finishes fixing the gas pipeline, the other mounting plate repeats the above operation, so that the two mounting plates 101 are respectively fixed to the two bent ends of the gas pipeline to ensure that the bent ends of the gas pipeline will not become loose during use, and the two mounting plates 101 can be switched to the horizontal state to clamp and fix the gas pipeline in a straight line distribution, so as to improve the practicability of the device.

[0033] In addition, a rotating rod 108 is threadedly connected to one side of each movable clamp 106. The end of each rotating rod 108 penetrates through the movable clamp 106 and is rotatably connected to an arc-shaped plate 109. An arc-shaped groove for fitting the arc-shaped plate 109 is provided on the inner wall of each movable clamp 106. A rubber pad 110 is fixedly connected to one side of each arc-shaped plate 109. A plurality of uniformly distributed circular protrusions are provided on one side of the rubber pad 110.

[0034] The arc-shaped plate 109 can be completely located within the arc-shaped groove of the movable clamp 106, thus not blocking the contact between the movable clamp 106 and the gas pipeline. After the fixed clamp 105 and the movable clamp 106 clamp and fix the gas pipeline, the rotating rod 108 is rotated to make its arc-shaped plate 109 disengage from the movable clamp 106 and perform secondary fastening and clamping on the gas pipeline to ensure the stability of the gas pipeline. The rubber pad 110 can prevent the arc-shaped plate 109 from damaging the gas pipeline. The rubber pad 110 can increase the friction between itself and the gas pipeline through multiple circular protrusions to prevent the gas pipeline from loosening and slipping within the fixed clamp 105 and the movable clamp 106.

[0035] Further, two spirit levels 205 are fixedly connected to the top of one of the mounting plates 101. The two spirit levels 205 are arranged in a T-shaped distribution. Limit plates 206 are fixedly connected to the bottoms of both mounting plates 101. A limit rod 207 is threadedly penetrated through one side of one of the limit plates 206. A circular hole that fits the limit rod 207 is opened on one side of the other limit plate 206. A cylinder 208 is fixedly connected to one side of one of the limit plates 206. The cylinder 208 communicates with the circular hole of the limit plate 206. A limit hole that fits the limit rod 207 is opened on one side of the cylinder 208.

[0036] The two horizontally and vertically distributed spirit levels 205 facilitate the user to observe whether the mounting plate 101 is installed horizontally to ensure that the distribution direction of the mounting plate 101 is consistent with that of the gas pipeline. When the two mounting plates 101 are in a horizontal state, the limit rod 207 passes through the two limit plates 206 and the cylinder 208, making the two mounting plates 101 maintain a horizontal state. By rotating the limit rod 207, the limit rod 207 can be made not to contact the cylinder 208 and the limit plate 206 connected to the cylinder 208. When the two mounting plates 101 are in a mutually perpendicular state, the limit rod 207 is rotated to pass through the limit hole of the cylinder 208. At this time, the two mounting plates 101 can be made to maintain a stable perpendicular state. The limit rod 207, the limit plate 206, and the cylinder 208 can reduce the pressure between the toothed plate 203 and the gear 202 and reduce the wear caused by the toothed plate 203 locking the gear 202.

[0037] During use, when it is necessary to fix the bent part of the gas pipeline, rotate the threaded rod 204 so that the teeth of the tooth plate 203 no longer mesh with the teeth of the gear 202. Then rotate the limit rod 207 so that it no longer contacts the cylinder 208 and the limit plate 206 connected to the cylinder 208. Then rotate the handle on the top of the gear 202 so that the two gears 202 drive the two mounting plates 101 to deflect by 90 degrees and be perpendicular to each other, and fit against the angle between the two walls. The mounting plates 101 can be fixed to the wall through fixing parts such as bolts and expansion screws. Then rotate the threaded rod 204 in the reverse direction so that the tooth plate 203 meshes with the teeth of the gear 202. Then rotate the limit rod 207 so that it passes through the limit hole of the cylinder 208 to fix the angle between the two mounting plates 101;

[0038] Then use one of the mounting plates 101 to clamp and fix the gas pipeline. Rotate the left - and - right - hand threaded screw rod 104 to make the two movable plates 102 on the mounting plate 101 approach each other. When the gas pipeline fits against the inner walls of the two fixed clamps 105, rotate the adjusting rods 107 of the two movable clamps 106 in the corresponding directions so that the two fixed clamps 105 and the two movable clamps 106 can clamp and fix the gas pipeline. Then rotate the rotating rod 108 so that its arc - shaped plate 109 and rubber pad 110 perform secondary fastening and clamping on the gas pipeline to ensure the stability of the gas pipeline. The other mounting plate 101 repeats the above operations to clamp and fix the gas pipeline on it. By fixing the two bent ends of the gas pipeline with the two mounting plates 101 respectively, it is ensured that the bent ends of the gas pipeline will not become loose during use.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
