Description

Technical Field

[0001] The utility model relates to the technical field of a machine platform or a bracket used as a support for an instrument or a product thereon, in particular to a level that is easy to adjust. Background Art

[0002] A level is an instrument for establishing a horizontal line of sight to measure the height difference between two points on the ground. The principle is to measure the height difference between ground points based on the principle of leveling. A Chinese utility model patent, authorization announcement number "CN218178418U", discloses a level that is easy to adjust the balance, including a tripod and a level. An outer disk is installed on the top of the tripod, an inner disk is installed between the inner parts of the outer disk through a snap-fit ​​mechanism, a top disk is installed on the top of the inner disk through an adjustment mechanism, a level is installed on the upper end surface of the top disk, a bubble disk is embedded on one side of the level at the top of the top disk, and the adjustment mechanism includes a "T"-shaped mounting seat.

[0003] The above technical scheme is set up, and the use of the pin rod in conjunction with the spring and the limit ring can realize the function of quick installation and disassembly of the tripod bracket and the level body, which is different from the traditional locking bolt installation method. At the same time, through the use of the "T"-shaped mounting seat and the sleeve seat, the balance of the level can be quickly adjusted. When measuring, it is often necessary to measure different positions. Each time a different position is measured, it is necessary to move to a different observation point. Due to the different terrain of the observation point, it is necessary to adjust the balance multiple times. At the same time, it is necessary to look at the numbers on the spirit level when observing. For people who are too tall, when using the spirit level, they need to frequently bend down, stand up, etc., which is very strenuous, thereby reducing the measurement efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and to provide an easily adjustable level that can solve the problem of a machine table or bracket used as a support for an instrument or a product thereon.

[0005] To achieve the above object, the utility model provides the following technical solution: a level that is easy to adjust, comprising a housing, the interior of the housing is rotatably connected to a second rotating shaft, the surface of the second rotating shaft rotates and penetrates the surface of the housing, and the surface of the second rotating shaft is fixedly connected to a worm;

[0006] The inside of the shell is rotatably connected with a first rotating shaft, the surface of the first rotating shaft is fixedly sleeved with a worm wheel, and the surface of the worm wheel is meshed with the surface of the worm.

[0007] Preferably, a connecting piece is fixedly connected to the surface of the first rotating shaft, and a level meter body is fixedly connected to the upper surface of the connecting piece;

[0008] Wherein, a rotating handle is fixedly connected to the surface of the second rotating shaft.

[0009] Preferably, the inner surface of the shell is rotatably connected to a threaded sleeve, the upper surface of the threaded sleeve is fixedly connected to a cylindrical member, and the surface of the cylindrical member is fixedly sleeved with a second gear.

[0010] Preferably, a motor is fixedly connected to the surface of the housing, a first gear is fixedly sleeved on the surface of the motor, and the surface of the first gear is meshed with the surface of the second gear.

[0011] Preferably, the internal thread of the threaded sleeve is connected to a threaded rod, and the lower surface of the threaded rod is fixedly connected to a level base.

[0012] Preferably, a slide bar is fixedly connected to the upper surface of the level base, a slide bar sleeve is slidably connected to the surface of the slide bar, and a surface of the slide bar sleeve is fixedly connected to the inside of the housing.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The level that is easy to adjust is provided with a motor, and the motor is started by an external power supply. The starting of the motor drives the first gear to rotate, and the rotation of the first gear drives the threaded sleeve to move. The movement of the threaded sleeve drives the outer shell to move up and down, and the movement of the outer shell drives the main body of the level to adjust the height of the main body of the level. By adjusting the height of the main body of the level, it can be adapted to people of different heights, thereby avoiding the inconvenience caused by the user being too tall and needing to frequently bend over or stand, thereby ensuring the measurement efficiency of the user.

[0015] (2) The level which is easy to adjust is provided with a slide bar and a slide bar sleeve. The slide bar sleeve is fixedly connected to the outer shell. The slide bar sleeve slides on the surface of the slide bar. The slide bar sleeve can limit the threaded sleeve from rotating when it moves, thereby ensuring that the outer shell can stably adjust the height up and down. By providing a rotating handle, the rotation of the rotating handle drives the worm to rotate, and the rotation of the worm drives the worm wheel to rotate. The worm wheel and the worm are worm gear transmission with a self-locking effect, that is, the worm can drive the worm wheel to rotate, but the worm wheel cannot drive the worm to rotate, thereby avoiding the gravity of the level body itself driving the worm wheel to rotate, causing the level body to deviate, thereby affecting the measurement, thereby ensuring its stability during measurement.
