The support 5 is arranged on the back of the back cover 1, and a placing included angle 7 is formed between the support 5 and the back cover 1. When the hygrothermograph is required to be placed, the support 5 directly supports the rear cover 1, so that the hygrothermograph can be placed more simply and conveniently. And the included angle 7 is arranged to further improve the supporting effect of the bracket 5 on the rear cover 1, so that the possibility of side turning of the hygrothermograph is reduced.

For convenience of description, hereinafter, a side close to the dial 2 is referred to as an inner side wall, and a side far from the dial 2 is referred to as an outer side wall.

Referring to fig. 1 and 3, the bracket 5 is rotatably coupled to the rear cover 1. Specifically, the support 5 includes supporting part 8 and sets up in the spliced pole 9 at backup pad both ends, and the lateral wall of spliced pole 9 runs through and has seted up rotation hole 10, wears to be equipped with axis of rotation 23 in rotating hole 10.

The back of the rear cover 1 is provided with a placing groove 11, the bracket 5 is accommodated in the placing groove 11, and two ends of the rotating shaft 23 are respectively fixedly connected with two opposite groove walls of the placing groove 11. A limiting member 12 for limiting the rotation of the bracket 5 is arranged in the placing groove 11, and the limiting member 12 is arranged on a groove wall of the placing groove 11 far away from the rotating shaft 23.

When the humiture timing is needed, the control bracket 5 rotates around the rotating shaft 23 in the circumferential direction, and the bracket 5 is accommodated in the accommodating groove 11, so that the space occupied by the humiture timing meter is reduced. At this time, the stopper 12 stops the gap therebetween, thereby reducing the possibility that the holder 5 is separated from the placement groove 11.

In addition, the cover is equipped with torsional spring 13 on the axis of rotation 23, and torsional spring 13 is located between two spliced poles 9, and the one end of torsional spring 13 and the inside wall butt of supporting part 8, the other end of torsional spring 13 and the tank bottom butt of standing groove 11. The groove wall of the placement groove 11 close to the rotation shaft 23 is welded with an abutting part 24, the abutting part 24 is obliquely arranged with the rear cover 1, and the outer side wall of the supporting part 8 abuts against the inner side wall of the abutting part 24.

When the temperature and humidity meter needs to be placed, the limiting piece 12 is separated from the support 5, the supporting portion 8 moves circumferentially around the rotating shaft 23 under the restoring action of the torsion spring 13, and the abutting portion 24 limits the supporting portion 8, so that the possibility of excessive rotation of the support 5 is reduced.

In this embodiment, the positioning holes 14 are formed through two opposite walls of the placing slot 11, and both the positioning holes 14 are disposed at one end of the placing slot 11 close to the rotating shaft 23. And both ends of the rotating shaft 23 are provided with limit nuts 15, and both ends of the rotating shaft 23 respectively penetrate through the two positioning holes 14 and are respectively in threaded connection with the two limit nuts 15. It should be noted that the aperture of the positioning hole 14 is smaller than the outer diameter of the limit nut 15.

In other embodiments, both ends of the rotating shaft 23 may be welded and fixed to the rear cover 1, and both ends of the rotating shaft 23 may be screwed to the rear cover 1.

Referring to fig. 4 and 5, the limiting member 12 includes a limiting block 16, a control shaft 17 disposed on the limiting block 16, a control block 18 disposed at an end of the control shaft 17 far from the limiting block 16, and a compression spring 19 sleeved on the control shaft 17.

Specifically, a slot 20 is formed on a wall of the placement groove 11 away from the rotation shaft 23, the compression spring 19 is accommodated in the slot 20, and the limit block 16 is movably inserted into the slot 20. The slot bottom of the slot 20 is provided with a control hole 21 in a penetrating way, the control shaft 17 is provided with the control hole 21 in a penetrating way and is in threaded connection with the control block 18, and the control shaft 17 is connected with the rear cover 1 in a sliding way.

So that the control block 18 can limit the movement of the control shaft 17 or the stopper 16, thereby reducing the possibility that the stopper 16 is completely separated from the slot 20.

In addition, the outer side wall of the stopper 16 is provided with a guide surface 22, and specifically, the guide surface 22 gradually deviates toward the inner side wall of the stopper 16 toward the direction close to the rotation shaft 23.

In the process of accommodating the bracket 5 in the accommodating slot 11, the inner side wall of the supporting portion 8 is firstly abutted against the guide surface 22, so that the supporting portion 8 gives a guiding force to the limiting block 16 through the guide surface 22, and the guiding force forces the limiting block 16 to be inserted into the slot 20.

Subsequently, the bracket 5 is continuously accommodated in the accommodating groove 11, when the supporting portion 8 is separated from the limit block 16, the limit block 16 is separated from the slot 20 under the restoring action of the compression spring 19, and the limit block 16 is further forced to limit the supporting portion 8, so that the control of the limit block 16 is simpler and more convenient.

The implementation principle of a hygrothermograph of the embodiment of the application is as follows:

when the temperature and humidity meter needs to be placed, the control block 18 is held at first, the control block 18 inserts the limit block 16 into the slot 20 through the control shaft 17, and the limit block 16 is enabled to be separated from the supporting portion 8.

At this moment, the supporting part 8 moves circumferentially around the rotating shaft 23 under the restoring action of the torsion spring 13, and the abutting part 24 limits the supporting part 8, so that the included angle 7 is formed, and the support 5 can better support the rear cover 1.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
