[0028] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0029] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present utility model.

[0030] The following describes a shock-proof device for an aneroid barometer for environmental monitoring provided by some embodiments of the present utility model with reference to the accompanying drawings.

[0031] Embodiment 1:

[0032] Combined with Figures 1-6 As shown, a shock-proof device for an aneroid barometer for environmental monitoring provided by the present utility model includes an aneroid barometer 300, four groups of shock-absorbing mechanisms 200 assembled outside the aneroid barometer 300, and a distance-adjusting traction mechanism 100 installed outside the four groups of shock-absorbing mechanisms 200.

[0033] The distance-adjusting traction mechanism 100 includes a base 110, an end post 120, a cushion plate 130, a cable 140, a protective outer cover 150, a limit sleeve 160, and a guard plate 170, and the shock-absorbing mechanism 200 includes a bearing plate 210, a beam rod 220, a top pressure pad foot 230, a baffle 240, a support rod 250, a spring 260, an auxiliary pressure pad part 270, and a bottom support 280.

[0034] Among them, the distance-adjusting traction mechanism 100 includes a base 110 placed on a platform and a protective outer cover 150 movably installed on the top of the base 110;

[0035] The shock absorption mechanism 200 includes a bearing plate 210 installed on the inner wall of the protective outer cover 150. The top and bottom of the bearing plate 210 are respectively installed with a first end and a second end. A baffle 240 is movably installed on the second end, a support rod 250 movably installed inside the baffle 240, a bottom support 280 movably installed at the bottom end of the support rod 250, a beam rod 220 movably installed on the first end, and a top pressing pad foot 230 movably installed at the outer end of the beam rod 220.

[0036] During the period from transportation to normal use of the aneroid barometer, temperature compensation measures need to be taken for protection. At the same time, the calibration value of the scale needs to be adjusted, and the difference in readings also needs to be pre-detected. These factors are directly related to vibration. Once the aneroid barometer is vibrated and impacted during use, it is very easy to cause errors in its values.

[0037] And this device provides shock absorption protection for the area where the aneroid barometer is put into use. By controlling the clockwise rotation of the protective outer cover 150, after the protective outer cover 150 descends towards the base 110, the four cable stays 140 can be in a relaxed state. At the same time, the four bottom supports 280 will lift obliquely upwards. At this time, the four springs 260 will pull the support rod 250 and the bottom support 280 to expand. At the same time, the auxiliary pressing pad member 270 will push the top pressing pad foot 230 to flip upwards. At this time, the exposed protective outer cover 150 and the four bottom supports 280 can facilitate the rapid assembly of the aneroid barometer 300. When the aneroid barometer 300 is placed on the tops of the four bottom supports 280, the operator can control the counterclockwise rotation of the protective outer cover 150. As the four cable stays 140 are tightened, the four bottom supports 280 can tighten the bottom of the aneroid barometer 300. Until the aneroid barometer 300 is suspended, the auxiliary pressing pad member 270 will also descend accordingly and cause the top pressing pad foot 230 to flip downwards, and finally the top of the aneroid barometer 300 can be secondarily limited, so as to avoid the influence of external environmental factors on the suspended aneroid barometer 300 and at the same time reduce the interference of vibration waves on the suspended aneroid barometer 300.

[0038] Embodiment 2:

[0039] Combined with Figures 3-5 As shown in the figure, on the basis of Embodiment 1, a screw hole is opened in the middle of the top surface of the base 110, and an end post 120 is installed in the middle of the screw hole, a backing plate 130 installed on the top of the end post 120, and four cable stays 140 connected inside the backing plate 130;

[0040] A threaded sleeve is opened at the bottom of the protective outer cover 150, and a limit sleeve 160 is installed inside the threaded sleeve and a guard plate 170 installed at the top of the inner cavity of the limit sleeve 160;

[0041] Notches for guiding the cable stays 140 are opened at the four ends of the guard plate 170.

[0042] By providing a hollow cavity inside the protective cover 150 and cooperating with the four suspended bottom supports 280 which are empty boxes, a suspended bearing platform is provided for the aneroid barometer 300. When the aneroid barometer 300 is clamped by the four bottom supports 280, the four bottom supports 280 in the natural state can tighten the bottom end of the aneroid barometer 300. As the protective cover 150 rotates, the threaded sleeve at the bottom of the protective cover 150 can rotate uniformly along the screw hole at the top of the base 110, and finally, in cooperation with the end post 120 and the backing plate 130, the four cables 140 can be tightened or relaxed, so as to provide a two-way tightening pressure for the loading and unloading of the aneroid barometer 300.

[0043] Embodiment 3:

[0044] Combined with Figures 3-6 As shown, on the basis of Embodiment 1, the top pressing foot 230 is made of silica gel, and a rubber layer is arranged on the outside of the top pressing foot 230;

[0045] Two slots are opened inside the top pressing foot 230, and auxiliary pressing pad members 270 are installed in the two slots;

[0046] The support rod 250 is composed of a T-shaped guide rod and a U-shaped chuck, and a spring 260 is arranged on the outside of the T-shaped guide rod. The bottom end of the spring 260 bears on the end plate at the bottom of the baffle 240;

[0047] The bottom support 280 is made of thickened rubber material, and a clamping plate is installed at the bottom of the bottom support 280, and the top end of the cable 140 is movably connected inside the clamping plate.

[0048] Using a plurality of bolts, the four bearing plates 210 are evenly distributed in the four grooves on the inner wall of the protective cover 150. At this time, the bearing plates 210 can provide a stable bearing capacity for the baffle 240, and in cooperation with the transfer of the support rod 250 and the spring 260 to the bottom support 280, at this time, the bottom support 280 can provide a stable bearing platform for the aneroid barometer 300, and the auxiliary pressing pad member 270 installed at the bottom of the support rod 250 can provide continuous traction kinetic energy for the free rotation of the top pressing foot 230.

[0049] The working principle and usage process of the present utility model: Pre-control the protective outer cover 150 to rotate clockwise until the protective outer cover 150 descends along the top of the base 110. At this time, the four cable stays 140 will be in a slack state, and the bottom support 280 will be lifted upward under the traction of the support rod 250. At the same time, the auxiliary pressure pad member 270 installed at the bottom end of the support rod 250 will push the top pressure pad foot 230 to turn upward. After the four top pressure pad feet 230 expand at the same speed, the four bottom supports 280 can be exposed. Then, the staff needs to place the aneroid barometer 300 into the inner cavity of the protective outer cover 150 until the four bottom supports 280 are snapped into the grooves at the bottom end of the aneroid barometer 300. Then, adjust the protective outer cover 150 to rotate clockwise;

[0050] As the protective outer cover 150 rotates counterclockwise along the top of the base 110, when the protective outer cover 150 is lifted upward, the four cable stays 140 pulled by the end post 120 can simultaneously stretch the four bottom supports 280 along the obliquely downward direction until the four bottom supports 280 tighten the bottom of the aneroid barometer 300. And as the four auxiliary pressure pad members 270 descend, they can cause the four top pressure pad feet 230 to turn downward until the four top pressure pad feet 230 turn downward and assist in pressing the top port of the aneroid barometer 300, so as to effectively ensure that the placed aneroid barometer 300 can be protected by suspension and shock absorption, thereby reducing the direct interference caused by human factors and environmental factors to the aneroid barometer 300.

[0051] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
