Description

Technical Field

[0001] The utility model relates to the technical field of gas detector circuit protection, in particular to a gas detector circuit protection structure. Background Art

[0002] A gas detector is a device used to monitor and measure the gas concentration in the environment. It can detect various gases, such as toxic gases, combustible gases, oxygen concentration in the air, etc. It can perform rapid detection in various environments. When the concentration of the detected gas in the environment exceeds the alarm value, an alarm will be issued in time.

[0003] In addition, gas detectors are usually composed of sensors, controllers, displays and external circuits. They are suitable for dangerous places where flammable or toxic gases exist, and can continuously detect the content of the measured gas in the air within the lower explosion limit for a long time;

[0004] In practical applications, gas detectors can detect gas leaks and send out sound, light and other alarm signals to remind people to take safety measures such as evacuation, forced exhaust, and equipment shutdown. They are an indispensable instrument in industrial production and daily life.

[0005] The external circuit of the gas detector is generally used to connect the network signal and power supply. It is mainly used for powering on and transmitting detection signals to the fire protection network to facilitate fire protection linkage.

[0006] However, when using the external cables, they are either directly exposed to the outside world at the connection point without protection, and are easily broken or damaged by collision;

[0007] Alternatively, a thicker pipe may be used to cover the outside of the line. However, since the pipe needs to have a certain hardness, it is not easy to bend and will take up a larger space. The line may enter from multiple directions, so the adaptability during installation is poor, causing inconvenience to the user. Utility Model Content

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] A gas detector line protection structure includes a detector 10. A line inlet pipe 20 is arranged on the side of the detector 10. The detector 10 is an existing gas detector. The line inlet pipe 20 is a connecting pipe used for external line inlet of the existing gas detector.

[0040] In the examples of this application, please refer to Figure 1 and 2A connecting tube 30 is provided on the side of the incoming line pipe 20, and the connecting tube 30 is rotatably connected to a rotating block 50. Specifically, a connecting tube 30 is provided with a communicating square hole 31 and a circular hole 32, and the circular hole 32 is close to the rotating block 50. A plug-in tube 52 is fixed to one side of the rotating block 50, and the plug-in tube 52 is rotatably arranged in the circular hole 32 through a bearing 53. At the same time, a through hole 51 as a curved hole is provided in the rotating block 50. When in use, the external line passes through the connecting tube 30 and the through hole 51 and then passes through. After being protected by the connecting tube 30 and the rotating block 50, it can avoid being knocked or broken. When needed, the rotating block 50 is rotated to rotate the angle of the line extension, so as to adapt to different incoming line directions, with better adaptability and less occupied space.

[0041] Furthermore, the rotating block 50 is fixedly connected with a protection tube 60 , which is communicated with the connecting tube 30 through the through hole 51 . The protection tube 60 can be connected to the direction in which the line enters, and is an existing line protection pipeline.

[0042] At the same time, the connecting tube 30 is connected to the incoming line tube 20 through a stabilizing structure 40. Specifically, the stabilizing structure 40 includes a sleeve 41 which is sleeved on the outside of the incoming line tube 20. The sleeve 41 is fixedly connected to the connecting tube 30. The sleeve 41 is threadedly connected with a screw 42. A limiting block 43 is fixed at the bottom of the screw 42. The limiting block 43 abuts against the incoming line tube 20. When in use, after the line passes through the protective tube 60, the through hole 51 and the connecting tube 30, the sleeve 41 is sleeved on the outside of the incoming line tube 20, and then the screw 42 is tightened so that the limiting block 43 abuts against the incoming line tube 20 to successfully connect. Otherwise, it can be removed. The operation is simple.

[0043] In another embodiment, see Figure 3 and 4 The square hole 31 is also provided with a tightening structure 70 for tightening the line. Specifically, the tightening structure 70 includes two movable blocks 71 relatively slidably arranged inside the square hole 31. The two movable blocks 71 are fixed with soft pads 72 on opposite sides. In order to facilitate clamping the line, the two soft pads 72 are concave on opposite sides. A guide rod 73 that passes through the movable block 71 is fixed inside the connecting tube 30. The sliding of the movable block 71 is guided by the guide rod 73. A rotatable rotating rod 72 that passes through the movable block 71 is rotatably arranged inside the connecting tube 30. Rod 74, the end of the rotating rod 74 is fixed with a knob 75 located outside the connecting tube 30, and the outside of the rotating rod 74 is provided with two sections of threads 76, and the two sections of threads 76 are in opposite directions and are respectively threadedly connected to the two movable blocks 71. When in use, the line passes between the two movable blocks 71, and then the knob 75 is rotated to drive the rotating rod 74 to rotate. Under the action of the two sections of threads 76, the two movable blocks 71 can be driven to move relative to each other, so that the line can be clamped in the end to prevent the line from moving at will, thereby ensuring the stability of the line.
