Background
Tunable laser modulation (TDLAS) is one of the gas sensing technologies developed in recent years, and the advantages of high accuracy, good reliability and long service life are widely paid attention to in the industry. The core of the technology is that the absorption peak of the gas is scanned through the modulation of the laser frequency, and then the second harmonic in the demodulated signal after the laser passing through the gas chamber is received to calculate the gas concentration. Because the volume of the sensor is limited, the gas chamber cannot be made long, so that the second harmonic wave containing the concentration signal after the laser passes through the gas chamber is very weak, and noise caused by scattered light must be reduced from an optical path as much as possible in addition to a high-resolution sampling electronic device for extracting the signal. The design of the air chamber is therefore particularly important.

The first spring 401c is a compression spring, and the movement of the stopper 401b is moved following the horizontal movement of the moving lever 401 d. The moving lever 401d is engaged with the first gear 402a through the first serration 401d-1 at the other end thereof. The first connecting plate 401e-1 is fixedly connected with the clamping block 401e, and two ends of the second spring 401f are respectively fixedly connected with the first connecting plate 401e-1 and the second connecting plate 401 e-2.

The cam 402c mates with a protrusion on the clamp block 401e, and when the cam 402c rotates, the position of the clamp block 401e changes. I.e. the clamping and unclamping of the clamping block 401e is directly controlled by the cam 402c and the second spring 401 f.
Preferably, the locking member 403 includes a hand pulley 403a disposed at the bottom of the inner pipe 401a, a limit hook 403b disposed on the bottom surface of the inner pipe 401a, and a third spring 403c disposed at the bottom of the hand pulley 403a, wherein the side surface of the hand pulley 403a is uniformly provided with third saw teeth 403a-1, the top surface of the hand pulley 403a is uniformly provided with limit teeth 403a-2, and one end of the third spring 403c is fixedly connected with the bottom of the hand pulley 403 a. The third serration 403a-1 is engaged with the second gear 402e, and when the hand pulley 403a rotates, the second gear 402e rotates. The limiting hooks 403b are metal elastic pieces and normally are buckled on the limiting teeth 403a-2, so that the hand pulley 403a only allows unidirectional rotation in this state. The third spring 403c is a compression spring, and mainly plays a role in restoring.
Further, the second fixing member 404 includes a first fixing base 404a disposed on an outer wall of the inner pipe 401a, and a second fixing base 404b disposed on an inner sidewall of the socket 301.
In use, the plug 302 is inserted directly into the socket 301 and then the hand pulley 403a is rotated with a finger in the identification direction until it is stationary, indicating that both the plug 302 and the socket 301 have been tightly connected together. In this process, when the bottom of the plug 302 is inserted into the inner pipe 401a, the stopper 401b will clamp the plug 302 under the action of the first spring 401c, so as to ensure the tightness. When the hand pulley 403a rotates, the second gear 402e is driven to rotate, and the second gear 402e in turn drives the first shaft 402d to rotate, thereby driving the cam 402c to rotate. The flange end of the cam 402c will clamp the clamping block 401e tightly to the plug 302 after rotating to a certain extent, so as to ensure the stability of the connection. The cooperation of the stop hook 403b and stop tooth 403a-2 on top of the hand pulley 403a allows it to rotate only in one direction, thereby avoiding loosening of the clamp block 401e due to the rotation of the hand pulley 403 a. When the disassembly is needed, only the hand pulley 403a is required to be downwards pulled in the direction shown in the drawing, and at the moment, the downward movement of the hand pulley 403a pulls the rack 402b to move downwards, so that the first gear 402a is driven to rotate, and the moving rod 401d is driven to move to pull the stop block 401b to two sides. At the same time, the hand pulley 403a moves downwards to be separated from the second gear 402e, and the second gear 402e loses the limit, and then the cam 402c also loses the blocking force, so that the clamping block 401e moves to two sides under the action of the second spring 401f, thereby facilitating the smooth pulling-out of the plug 302. The whole device has compact structure and simple operation, and can ensure certain good air tightness under the condition of ensuring stable connection.
It should be noted that the above embodiments are only for illustrating the technical solution of the present application and not for limiting the same, and although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the present application may be modified or substituted without departing from the spirit and scope of the technical solution of the present application, which is intended to be covered in the scope of the claims of the present application.
