Embodiment Construction
[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0031] like Figure 1~4 Shown is the first embodiment of the present invention.
[0032] A pressure gauge, comprising a watch case 1, a dial 2 placed in the watch case 1, a pointer 4, and a conversion structure for transmitting pressure deformation to the pointer 4 to cause the pointer 4 to rotate. The dial 2 is provided with a pressure scale, The bottom of the watch case 1 is provided with an introduction hole 111 for introducing external pressure and acting on the conversion structure.
[0033] The conversion structure includes a transmission rod 3, which is axially constrained in the watch case 1 and can rotate around its own axis. The transmission rod 3 is provided with a transmission external thread 31. The pitch of the transmission external thread 31 is relatively large. The pointer 4 and the upper end of the transmission rod 3 fixed. ...
