Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

As shown in fig. 1 to 7, a stylus level includes a housing 1 made of transparent material, which has good light transmittance and is convenient for observation and use, the housing is formed with a closed cavity, the closed cavity is filled with a liquid, the liquid is a liquid with a small viscosity coefficient, such as any one of oil, alcohol or ether, in this embodiment, the liquid is oil, and by filling the closed cavity with the liquid, the effects of amplification, impact resistance and rust protection of the components inside can be achieved.

Be provided with the body of rod 2 in the closed cavity, the both ends of the body of rod 2 are rotated and are connected at the both sides inner wall of shell 1, specifically, shell 1 is including setting up the side end plate 13 in both sides, and the both ends of the body of rod 2 are provided with bulb 8, and the inner wall middle part of side end plate 13 is provided with concave sphere 131, and bulb 8 rotates to be connected on concave sphere 131, through the supporting setting of bulb 8 with concave sphere 131, can reduce the frictional force of bulb 8 between rotation in-process and concave sphere 131, makes the body of rod 2 can smoothly rotate.

The middle part of the rod body 2 is rotatably connected with a rotating needle component, the shell 1 is provided with a convex lens 3, the convex lens 3 corresponds to the rotating needle component, the circumferential edge of the convex lens 3 is provided with a graduated scale 4, the graduated scale 4 displays the angle numerical value, the rotating needle component comprises a rotating body 5, a connecting rod 6 and a pointer 7, the rotating body 5 is rotatably connected with the middle part of the rod body 2, specifically, the middle part of the rod body 2 is provided with a first connecting hole 21, the middle part of the rotating body 5 is provided with a second connecting hole 51, the first connecting hole 21 is correspondingly used with the second connecting hole 51, the rotating body 5 can be rotatably connected with the rod body 2 by driving a pin into the second connecting hole 51 to be connected with the first connecting hole 21, the rotating body 5 is arranged to be a structure which is heavy and light, in the embodiment, the rotating body 5 is arranged to be triangular, the upper end is pointed, light and the lower end is heavy, therefore, under the action of universal attraction, after the rotation of the rotator 5 stops, the lower end of the rotator 5 is always located right below, the upper end of the rotator 5 is connected with one end of the connecting rod 6, and the other end of the connecting rod 6 is connected with the pointer 7, as can be seen from the above-mentioned structure, by taking fig. 2 and fig. 7 as examples, the pointer 7, the connecting rod 6 and the rotator 5 are connected into a whole, and no matter the housing 1 is placed horizontally, laterally deviated (i.e. one end is higher and the other end is lower) or even rotates with the second connecting hole 51 as the center of circle, the pointer 7 can be automatically righted by the pulling of the rotator 5, i.e. automatically corrected to be vertically downward. Because the rotating needle component is connected and installed on the front end face of the rod body 2, the balance weight strip 9 is arranged in the middle of the rear end face of the rod body 2, so that the front end face and the rear end face of the rod body 2 are balanced in stress, and lateral deviation cannot occur.

The shell 1 is set to be cuboid, and the shell 1 is including the front end plate 11 that links to each other in proper order, upper end plate 12 and back end plate 13, and the middle part of front end plate 11, upper end plate 12 and back end plate 13 is equallyd divide and is provided with convex lens 3 respectively, makes the three homoenergetic of this shell 1 use, and the rotation of the body of rod 2 in the shell 1 sets up, also be convenient for the front end plate 11, upper end plate 12 and back end plate 13 these three face can both select in a flexible way and use.

As shown in fig. 5, the rod 2 is symmetrical in structure at two sides with the first connecting hole 21 as the center, and is set to be a shape that the rod is smoothly and gradually narrowed from the first connecting hole 21 to the ball heads 8 at two sides, which is helpful to reduce the resistance of the rod 2 in the rotating process and improve the flexibility of the rotation.

The working principle of the rotating needle type level meter is as follows: taking the observation by the convex lens 3 in the front end plate 11 as an example, the stylus type level is entirely placed on an object to be measured, if the object to be measured is horizontal, the shell 1 of the stylus type level is also horizontal, the pointer 7 in the stylus assembly points to the vertical downward direction, and if the pointer 7 points to the scale of 0 degree in the graduated scale 4 at the moment; if the measured object is inclined, the bottom surface of the housing 1 is attached to the measured object, so that the whole housing 1 is also inclined, the convex lens 3 (the graduated scale 4) is also inclined by a certain angle of rotation, and the pointer 7 is also vertically downward under the action of the rotating body 5, and if the pointer 7 indicates a 5-degree scale in the graduated scale 4, the inclination of the measured object by 5 degrees can be accurately known, so that the measured object can be adjusted and corrected correspondingly, and the device is very convenient and has strong practicability.
