[0022] Front end protection unit includes limit ring 203, front end plugging ring 204, transparent shielding piece 205, compression spring 206;Limit ring 203 is fixed in the inside of C type outer cover 201, and front end plugging ring 204 is fixed in the front end of C type outer cover 201, and limit ring 203 is attached to the front end of the shell of pressure gauge 1;Transparent shielding piece 205 is slidably connected in the inside of C type outer cover 201 and is located in the intermediate region of front end plugging ring 204 and limit ring 203, and compression spring 206 is distributed in the inside of C type outer cover 201 and is located in the intermediate of transparent shielding piece 205 and limit ring 203.

[0023] The compression spring 206 is used to provide a pushing force for the transparent shield 205 towards the front end sealing ring 204, so as to make the transparent shield 205 away from the front end glass of the pressure gauge 1, and when the transparent shield 205 is impacted by an external object, the compression spring 206 is used to provide a buffering effect through the contraction deformation.

[0024] In the embodiment, when the pressure gauge 1 is installed and used, the anti-collision protection of the pressure gauge 1 can be realized through the protection assembly 2, and the principle is as follows:

[0025] First, the C-shaped cover 201 is sleeved on the outer side of the watch case of the pressure gauge 1 through the two arc-shaped corrugated clamping plates 202, the bottom gap of the C-shaped cover 201 is used to avoid the joint at the bottom of the pressure gauge 1, finally, the limiting ring 203 is attached to the front end of the watch case of the pressure gauge 1, at this time, the transparent shield 205 forms a shield for the front end of the pressure gauge 1, and the C-shaped cover 201 forms a shield for the watch case of the pressure gauge 1, so that the glass sheet at the front end of the pressure gauge 1 and the watch case of the pressure gauge 1 are prevented from being directly contacted and collided by external objects, thereby achieving the shielding and anti-collision protection effect.

[0026] When an external object collides with the transparent shield 205, the transparent shield 205 can be contracted towards the rear end and press the compression spring 206 to further contract, and the reaction force of the compression spring 206 can buffer and offset the impact force.

[0027] When an external object collides with the outside of the C-shaped cover 201, the arc-shaped corrugated clamping plate 202 will be deformed and contracted, so as to buffer and offset the impact force, thereby achieving a certain buffering protection effect.

[0030] The inner diameter size of the other two arc-shaped corrugated clamping plates 202 is less than the outer diameter of the outer shell of the pressure gauge 1, so that when the protection assembly 2 is installed, the two arc-shaped corrugated clamping plates 202 are in a deformed and contracted state, at this time, the two arc-shaped corrugated clamping plates 202 form a clamping effect on the outer shell of the pressure gauge 1, thereby realizing the installation and fixation of the protection assembly 2.

[0031] Please refer to Figs. 3-5The inner diameter of the limiting ring 203 matches the inner diameter of the front end edge of the pressure gauge 1 shell, the inner diameter of the front end blocking ring 204 is greater than the inner diameter of the front end edge of the pressure gauge 1 shell, and the transparent shielding sheet 205 is made of transparent acrylic material.
