The level bubble 3 is used as a level indicator to help experimenters quickly determine whether the pressure gauge body 1 is placed stably. If the bubble in the level bubble 3 is centered, it means that the pressure gauge body 1 is roughly horizontal. If the bubble is not centered, leveling is required. The left and right ends of the shell 11 are respectively symmetrically provided with combination grooves 2. The combination groove 2 consists of an adjustment groove 1 21 and an adjustment groove 22. The adjustment groove 1 21 and the adjustment groove 22 are respectively symmetrically provided at the left and right ends of the shell 11. The adjustment groove 22 is a vertical rectangular The top of the second adjusting groove 22 is respectively connected with the inside of the horizontally arranged adjusting groove 1 21, and the inside of the adjusting groove 1 21 and the adjusting groove 2 22 are respectively provided with an adjusting assembly 5, and the adjusting assembly 5 is composed of a driving assembly 51, a lifting assembly 52 and a lifting column 53. The driving assembly 51 is respectively rotatably installed in the inside of the adjusting groove 1 21, and the driving assembly 51 drives the lifting assembly 52 rotatably installed on the top of the inner side of the adjusting groove 2 22, and the bottom of the lifting assembly 52 is respectively threadedly connected with the lifting column 53 slidably installed in the inside of the adjusting groove 2 22, and also includes a support block 4, and the support block 4 is provided with four, and the support blocks 4 are respectively fixedly installed at the bottom of the lifting column 53, and the support block 4 is a circular silicone block, and the support block 4 is a circular silicone block, which has a certain The elasticity and anti-slip properties can increase the stability of the pressure gauge. The bottom of the adjusting groove 22 is respectively provided with a storage groove 6. The storage groove 6 is a circular structure. The height and diameter of the storage groove 6 are respectively greater than the height and diameter of the support block 4. By storing the support block 4 in the storage groove 6, it is possible to avoid the support block 4 and the lifting column 53 being skewed by collision with external objects during transportation, which affects the accuracy of leveling the pressure gauge body 1. The lifting assembly 52 includes a threaded rod 521, a worm gear 522 and a tapered roller bearing 523. The threaded rod 521 is respectively arranged inside the adjusting groove 22. The top of the threaded rod 521 is rotatably connected to the inner top of the adjusting groove 22 through the tapered roller bearing 523. The top of the threaded rod 521 is respectively fixed A worm wheel 522 is installed, and the bottom of the threaded rod 521 is threadedly connected with the screw hole set in the center of the top of the lifting column 53. The driving component 51 includes a knob 511, a worm 512 and a bearing 513. The worm 512 is respectively arranged inside the adjusting groove 21, and one end of the worm 512 is rotatably connected to the inner side of the adjusting groove 21 through the bearing 513. The worm 512 is respectively meshed with the teeth on the worm wheel 522. The lead angle of the worm 512 is less than the equivalent friction angle between the meshing worm wheels 522 to ensure that the worm 512 and the worm wheel 522 are self-locking. The other end of the worm 512 is fixedly installed with a knob 511. By rotating the knob 511, the worm 512 drives the worm wheel 522 to drive the threaded rod 521 to rotate.As a result, the lifting column 53 threadedly connected to the bottom of the threaded rod 521 moves up and down along the inner side of the second adjustment groove 22, so that the level of the pressure gauge body 1 can be adjusted.

[0017] The working principle of the utility model is as follows: when in use, the pressure gauge body 1 is placed on an external experimental table, and the pressure gauge body 1 is ensured to be in a horizontal state by observing the level bubble 3. If the bubble in the level bubble 3 is not centered, it means that the pressure gauge body 1 needs to be adjusted to a horizontal state. If the bubble in the level bubble 3 is centered, it means that the pressure gauge body 1 is roughly horizontal. If the pressure gauge body 1 is not in a horizontal state, the experimenter can adjust the pressure gauge body 1 by adjusting the adjustment component 5 in the combination groove 2. The specific steps are as follows: the experimenter rotates the knob 511 at the tilted end of the pressure gauge body 1 to drive the worm 512 to rotate, and the worm 512 is meshed with the worm wheel 522, so that the worm wheel 522 And the threaded rod 521 connected to it rotates. Since the threaded rod 521 is threadedly connected to the lifting column 53, at the same time, the lifting column 53 is matched and slidably installed in the adjusting groove 22 which is a rectangular groove, so that the rotating threaded rod 521 can drive the lifting column 53 to move up and down along the adjusting groove 22 to adjust the height of the inclined end of the pressure gauge body 1, thereby achieving the purpose of adjusting the pressure gauge body 1 to a horizontal state; during the transportation of the pressure gauge body 1, the experimenter can lower the lifting column 53 to the lowest position so that the support block 4 is stored in the storage groove 6 to avoid the support block 4 and the lifting column 53 being colliding with external objects during transportation, resulting in skewness, affecting the accuracy of the leveling of the pressure gauge body 1.
