When the carbon dioxide concentration meter main body 1 needs to be used outdoors, the locking rod 12 is only required to be pulled out of the lock hole, the driving shaft 10 is driven to rotate reversely through the rotary disc 11, the pulling force of the driving shaft 10 on the first pulling rope through the first winding wheel 16 gradually disappears, the first spring 23 and the elastic force of the torsion spring are released, the movable block 20 is driven to return to the initial position, and the box cover 3 is opened.
The driving shaft 10 drives the first transmission shaft 6 to rotate reversely through the second bevel gear 9 and the first bevel gear 8, so that the first transmission shaft 6 and the screw 13 are in threaded interaction, and the support plate 5 moves upwards under the limiting action of the first telescopic rod 14, so that the main body 1 of the carbon dioxide concentration meter extends out of the top opening of the box body 2, and the carbon dioxide concentration in the outdoor environment can be detected.
Furthermore, the first transmission shaft 6 drives the first synchronizing rod 25 to rotate reversely, so that the roller 37 on the end of the first synchronizing rod 25 rotates reversely, the extrusion force on the inclined surface of the pressing block 38 is gradually reduced, the third spring 44 releases the elastic force to push the sliding block 42, the connecting rod 43 returns to the initial position in the sliding groove 41, and the connecting rod 43 pushes the pressing block 38 to return to the initial position, so that the handle 39 is accommodated in the accommodating groove 40 again. Meanwhile, the reverse rotation of the first synchronizing rod 25 also enables the fourth bevel gear 28 to reversely rotate under the limiting effect of the third bevel gear 24, and the reverse rotation is transmitted to the fifth bevel gear 29, the sixth bevel gear 31 and the third transmission shaft 30 through the second transmission shaft 27, so that the second synchronizing rod 32 reversely and circumferentially rotates, the clamping groove 33 on the second synchronizing rod 32 is gradually separated from the position right above the clamping bead 36, the clamping bead 36 is forced to be separated from the clamping groove 33, the locking state between the second synchronizing rod 32 and the pressing block 38 is released, and finally the locking rod 12 is inserted into the corresponding locking hole in the box body 2.
Example 2
The difference between this embodiment and embodiment 1 is that a rotating hole (not shown) is formed in the rotating disc 11 for the locking rod 12 to rotate in the circumferential direction and to slide in the axial direction, and the locking rod 12 is connected with the locking hole in a threaded fit manner, so as to effectively fix the rotating position of the rotating disc 11.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
