As shown in fig. 2, the latch device 5 includes a hook 51 perpendicular to and fixedly connected with the opening side of the observation shell 4, a hook opening of the hook 51 is arranged in a direction away from the center of the observation shell 4, and a latch mechanism 52 matched with a back side inclined plane of the hook opening of the hook 51 is arranged in the side wall of the support shell 3 corresponding to the hook 51, a spring 53 parallel to the opening plane of the support shell 3 is fixedly connected between the latch mechanism 52 and the side wall of the support shell 3, so that when the hook 51 is pushed by external force to move towards the latch mechanism 52, the push spring 53 contracts, and the hook 51 can be latched with the latch mechanism 52 under the restoring force of the spring 53 when the external force is released to limit the latch mechanism 52, and a release device 54 is further arranged to facilitate the separation of the hook 51 from the latch mechanism 52. The unfreezing device 54 comprises a telescopic rod 55 arranged in a spring 53, a reset plate 56 which is perpendicular to and fixedly connected with the telescopic rod 55 is sleeved outside the telescopic rod 55, the reset plate 56 is fixedly connected with one end of the spring 53, which is far away from the clamping piece mechanism 52, a positioning plate 57 with the inner diameter smaller than that of the reset plate 56 is sleeved outside the spring 53, the positioning plate 57 is arranged between the clamping piece mechanism 52 and the reset plate 56 and does not contact with the spring 53, namely the expansion process of the spring 53 is not influenced, the positioning plate 57 is parallel to the reset plate 56 and is connected with a reset rod 58, the reset rod 58 is parallel to the expansion direction of the telescopic rod 55, one end of the reset rod 58 penetrates through the side wall of the supporting shell 3 to be communicated with the outside, so that the reset rod 58 is pulled to drive the positioning plate 57 to move to the position which is contacted with the reset plate 56, the reset rod 58 is pulled to further pull, the dial plate 1 inside is convenient to maintain and replace.

In order to facilitate the switching of hanging installation and vertical placing to the hygrothermograph, as shown in fig. 3, observe that shell 4 deviates from dial plate 1 one side outer wall and is provided with holding tank 12, be provided with bracing piece 6 in the holding tank 12, 6 one end fixedly connected with of bracing piece rather than vertically articulated shaft 7, and bracing piece 6 keeps away from articulated shaft 7 one side and is provided with slipmat 17. As shown in fig. 4, one end of the hinge shaft 7 penetrates through the side wall of the accommodating groove 12 and is fixedly connected with a ratchet 8, the outer wall of the observation shell 4 is fixedly connected with a pawl 9 matched with the ratchet 8, and the observation shell 4 is also fixedly connected with a resetting device 10 matched with the pawl 9. Meanwhile, the support rod 6 is provided with a mounting hole 11 for hanging the hygrothermograph. In order to strengthen the supporting effect to the hygrothermograph when there is certain angle between bracing piece 6 and the support shell 3, bracing piece 6 articulates towards support shell 3 one side has anchor strut 13, anchor strut 13 one end is articulated with bracing piece 6, the other end articulates there is slider 14 with holding tank 12 complex, holding tank 12 lateral wall is provided with rack 15 simultaneously, slider 14 is connected with the elasticity latch 16 (not marked in the figure) with rack 15 meshing, thereby can fix a position the removal of slider 14 in holding tank 12, strengthen anchor strut 13's stability.

The implementation principle of the embodiment is as follows: when the thermometer is used, the thermometer can be directly connected through the mounting hole 11 when the thermometer is required to be hung, when the thermometer is required to be placed on a table top or other ground, the supporting rod 6 is pulled, the thermometer is enabled to rotate out of the accommodating groove 12 around the hinged rod under the action of the ratchet 8 and the pawl 9, and the positioning is realized at a required position. The slider 14 moves towards the direction of the hinge rod along the sliding groove in the rotating process of the support rod 6, and meanwhile, the slider is kept stable under the clamping effect of the elastic clamping teeth 16 (not marked in the figure) and the rack 15, so that the support rod 6 is supported, and the stability of the hygrothermograph when being placed is enhanced. When the support rod 6 is accommodated, the reset device 10 is pulled to separate the pawl 9 from the ratchet wheel 8, so that the support rod 6 can be accommodated into the accommodating groove 12. When the observation shell 4 and the support shell 3 need to be separated, the positioning plate 57 is pulled to be in contact with the reset plate 56, and the positioning plate 57 is continuously pulled towards the outside of the support shell 3, so that under the action of external force, the reset plate 56 is driven to move through the positioning plate 57, and then the telescopic rod 55 fixedly connected with the reset plate 56 is driven to contract, the separation of the clamping hook 51 and the clamping piece mechanism 52 is further realized, and the separation between the observation shell 4 and the support shell 3 is also completed.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
