Description

Technical Field

[0001] The utility model relates to the technical field of level instruments, in particular to a portable level instrument device. Background Art

[0002] The frame level is a precision tool used to measure and adjust the horizontal position and slight inclination of a plane, and is usually used in mechanical processing, construction and other fields. The frame level is designed with the user's convenience in mind, such as the easy-to-hold frame shape and clear level bubble display, which all help to improve the convenience of use.

[0003] When using a frame level to measure the vertical surface of a workpiece, you cannot hold the part opposite to the auxiliary side surface, but push hard against the vertical plane of the workpiece. This will cause the level to deform due to the force, affecting the accuracy of the measurement. The correct measurement method is to hold the inner side of the auxiliary measuring surface with your hand, so that the level is firmly and vertically attached to the vertical plane of the workpiece, and then read the number of grids moved by the bubble from the longitudinal level. The main body of the existing frame level is mostly made of cast iron and is heavy. In order to facilitate the fixing of the frame level on the vertical plane of the workpiece and reduce the holding time of personnel, some existing frame levels will set a permanent magnet on one side to fix the frame level on the vertical plane of the workpiece by magnetic attraction.

[0004] However, since the main body of the frame level is made of cast iron, the permanent magnet needs to have a strong magnetic attraction force during magnetic attraction. When the frame level is close to the workpiece, the large magnetic force can easily cause the frame level to collide with the workpiece, affecting the accuracy of the level. Some glass bubble tubes may also be damaged due to impact. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figure 1-Figure 4 The utility model provides a technical solution: a portable level device, comprising: a rectangular frame 1, a first bubble tube 3 and a permanent magnet 6, the three side walls of the rectangular frame 1 are provided with V-shaped grooves 2, and planes are provided on both sides of the top of the V-shaped groove 2, so that the V-shaped groove 2 can be used for measuring the horizontality of the plane and the horizontality of workpieces such as shaft cylinders, a permanent magnet 6 is provided on the other side wall, a first bubble tube 3 is provided at the bottom of the rectangular frame 1, a second bubble tube 4 is provided at one end of the top of the first bubble tube 3, the clamping angle of the setting direction of the first bubble tube 3 and the second bubble tube 4 is 90 degrees, the first bubble tube 3 is horizontally arranged in the left-right direction, and the second bubble tube 4 is horizontally arranged in the front-back direction.

[0021] The inner wall of the rectangular frame 1 is provided with a reinforcing rib 5, and the inner wall of the rectangular frame 1 near the permanent magnet 6 is provided with a fixing plate 7, and a guide rod 8 is movably connected inside the fixing plate 7, and a buffer plate 10 is provided at one end of the guide rod 8, and a reset spring 9 is provided between the buffer plate 10 and the fixing plate 7. Hold the entire level by hand, point one side of the permanent magnet 6 toward the vertical plane to be measured of the workpiece, and gradually bring the level closer to the workpiece. When the level contacts the workpiece, the buffer plates 10 on both sides of the rectangular frame 1 first contact the vertical surface of the workpiece, and the level gradually approaches the workpiece through the magnetic force of the permanent magnet 6 and the force applied by the personnel. At this time, the elastic force of the reset spring 9 generates resistance to the magnetic force of the permanent magnet 6 and the force applied by the personnel, so as to prevent the level from being directly adsorbed on the workpiece under the action of the magnetic force and causing a collision.

[0022] A stopper 11 is provided at one end of the guide rod 8 away from the buffer plate 10, a guide hole is provided inside the fixing plate 7, one end of the guide rod 8 passes through the guide hole, four fixing plates 7 are provided, one buffer plate 10 corresponds to two guide rods 8, there are two buffer plates 10, and the two buffer plates 10 are respectively located on both sides of the rectangular frame 1. A connecting plate 12 is provided between the fixing plates 7 on both sides, a pull rod 13 is provided between the middle parts of the connecting plates 12, a fixing column 14 is provided on the outer wall of the reinforcing rib plate 5, a through hole is provided in the center of the connecting plate 12, the fixing column 14 passes through the center of the through hole, a conical positioning column 15 is provided at one end of the fixing column 14, and the diameter of one end of the conical positioning column 15 is larger than the diameter of the through hole. When the plane on one side of the rectangular frame 1 with the permanent magnet 6 is in complete contact with the workpiece, the reset spring 9 is compressed and one side of the buffer plate 10 is also in contact with the vertical surface of the workpiece. At this time, in order to avoid the buffer plate 10 exerting force on the workpiece and causing inaccurate level test, it is necessary to manually pull the pull rod 13 outward to drive the connecting plate 12 to move outward, so that the through hole on the connecting plate 12 forms an interference fit with the outer wall of the conical positioning column 15, thereby fixing the connecting plate 12, thereby separating the buffer plate 10 from the workpiece, and avoiding the problem of inaccurate level test caused by the buffer plate 10 exerting force on the workpiece.

[0023] The conical positioning column 15 is in the shape of a cone with a small diameter at one end and a large diameter at the other end. The end with a small diameter of the conical positioning column 15 is connected to the fixed column 14. A through cross groove is provided inside the conical positioning column 15. The conical positioning column 15 is equally cut into four parts by the cross groove. Through the cross groove in the middle of the conical positioning column 15, when the through hole of the connecting plate 12 and the conical positioning column 15 are interference-fitted, the conical positioning column 15 can produce a certain deformation toward the center to ensure the stability of the connection between the conical positioning column 15 and the connecting plate 12. When the connecting plate 12 needs to be released, it is only necessary to pinch the conical positioning column 15 by hand to make the conical positioning column 15 further deform inward, so that the conical positioning column 15 can be separated from the through hole.

[0024] A rubber pad is provided on one side of the buffer plate 10 to provide buffering to avoid damage to the vertical surface of the workpiece. A reset spring 9 is sleeved on the outside of the guide rod 8 to ensure the stability of the guide rod 8.

[0025] When the portable level device is in use, the frame-type level is easy to hold and move. When it is necessary to measure the vertical plane of the workpiece, the entire level is held in the hand, one side of the permanent magnet 6 is directed toward the vertical plane to be measured of the workpiece, and the level is gradually brought closer to the workpiece. When the level contacts the workpiece, the buffer plates 10 located on both sides of the rectangular frame 1 first contact the vertical surface of the workpiece, and the level is gradually brought closer to the workpiece through the magnetic force of the permanent magnet 6 and the force applied by the person. At this time, the elastic force of the reset spring 9 generates resistance to the magnetic force of the permanent magnet 6 and the force applied by the person, so as to prevent the level from being directly adsorbed on the workpiece under the action of the magnetic force and causing a collision.

[0026] When the plane on one side of the rectangular frame 1 with the permanent magnet 6 is in complete contact with the workpiece, the reset spring 9 is compressed, and one side of the buffer plate 10 is also in contact with the vertical surface of the workpiece. At this time, in order to prevent the buffer plate 10 from exerting force on the workpiece and causing inaccurate level test, it is necessary to manually pull the pull rod 13 outward to drive the connecting plate 12 to move outward, so that the through hole on the connecting plate 12 forms an interference fit with the outer wall of the conical positioning column 15, thereby fixing the connecting plate 12, thereby separating the buffer plate 10 from the workpiece, and avoiding the problem of inaccurate level test caused by the buffer plate 10 exerting force on the workpiece. The entire level, through the buffering of the buffer plate 10 and the reset spring 9, avoids the collision between the level and the vertical surface of the workpiece, and by pulling back the buffer plate 10, avoids the influence of the buffer device on the measurement during the level test, thereby ensuring the accuracy of the level measurement.

[0027] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
