Problems solved by technology

The detection gas enters the sensor for detection by means of dispersion. Since the installation direction of the sensor axis is horizontal, the overall size of the detection equipment increases. During the gas sampling process, the detection gas cannot fully enter the front end of the sensor, which affects the response time of the sensor.

specific Embodiment approach 1

[0012] An angle reducer 1 of an explosion-proof structure, including a large shoulder 9, a small shoulder 8, and a front external thread 7; it is characterized in that: the large shoulder 9 is connected to the small shoulder 8, and the small shoulder 8 is connected to the front outer thread The thread 7; the connecting body composed of the large shoulder 9, the small shoulder 8 and the front external thread 7 forms a horizontal axis inner hole 10 and a vertical axis inner hole 11 inside.

specific Embodiment approach 2

[0014] An angle reducer 1 with an explosion-proof structure includes a horizontal axis part and a vertical axis part. The horizontal axis part is composed of the front external thread 7, the small shoulder 8, and the horizontal axis inner hole 10. The front external thread 7 is connected with the inner screw interface of the detector 5 to form a horizontal thread explosion-proof structure 6; the vertical axis part is composed of the bottom internal thread, The large shoulder 9 and the inner hole 11 of the vertical axis are formed, and the internal thread at the bottom end is connected with the external thread of the sensor 3 to form a vertical thread explosion-proof structure 2 . The bottom of the detector 5 is provided with a detector bottom interface 4; the small shoulder 8 connects the front external thread 7 and the large shoulder 9, and the inner hole 10 of the horizontal axis and the inner hole 11 of the vertical axis form a cable connection cavity.

Abstract

The invention discloses a bend reducer of an anti-explosion structure. The bend reducer comprises a large shoulder, a small shoulder and front end external threads, and is characterized in that the large shoulder is connected to the small shoulder, and the smaller shoulder is connected to the front end external threads; a cross shaft inner hole and a vertical shaft inner hole are formed inside a connecting body consisting of the large shoulder, the small shoulder and the front end external threads. The bend reducer has the beneficial effects of simple structure and reliable anti-explosion performance, vertical mounting of a sensor can be realized, and thus the detection precision of the sensor is promoted.

Description

Technical field [0001] The present invention involves a kind of bending diameter, especially the corner variable diameter of an explosion -proof structure. Background technique [0002] At present, in the explosive gas detection environment, when the detection equipment uses a mobile regional detector, the entire detection equipment is powered by a battery in the inside of the explosion -proof power supply box., The right end interface is connected to the sound light alarm.The detection gas enters the sensor to detect it through the dispersing method. Because the installation direction of the sensor shaft heart is horizontal, the overall size of the detection equipment increases. During the gas sampling process, the gas cannot be fully entered into the front end of the sensor, affecting the response time of the sensor. Invention content [0003] In response to the above problems, the purpose of the present invention is a kind of bending diameter that can meet the explosion -proo...
