Description

Technical Field

[0001] The utility model relates to the technical field of levels, in particular to a support frame for a level. Background Art

[0002] As an indispensable detection tool in modern industry, the level is widely used in civil engineering, aviation and navigation, industrial control and other fields. The level has evolved from the simple bubble level in the past to the current electronic level, and the measurement accuracy and convenience have been greatly improved. The bubble level has a large error and is powerless for precise measurement of small angles. As a substitute for the traditional bubble level, the electronic level is more widely used in road engineering, mechanical measurement, construction engineering, industrial platforms, oil exploration, military industry, ships, and other situations that require inclination or level under the gravity reference system. When using the level, the support frame needs to be stably placed on the ground, and then the level is installed on the support frame for measurement. In general, the level needs to measure in multiple directions, and the support frame needs to be rotated when adjusting the direction. However, the rotation of the support frame is prone to angle deviation and needs to be recalibrated, which affects the progress of the work. To this end, we propose a level support frame to solve the above problems. Utility Model Content

[0016] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0017] The utility model proposes a level support frame, including a bracket 1, a fixed plate 3 is arranged above the bracket 1, a turntable 4 is arranged above the fixed plate 3, the top of the turntable 4 is used to install the level, a rotating shaft 41 is fixedly arranged at the bottom of the turntable 4, the rotating shaft 41 is rotatably arranged inside the fixed plate 3, and the use direction of the level can be changed by rotating the turntable 4 on the fixed plate 3, and the rotating shaft 41 is preferably connected to the fixed plate 3 by a bearing, including but not limited to a friction type rotation connection, etc., the top of the turntable 4 has a plurality of mounting grooves 31 in an annular array, and a spring 32 is arranged in the mounting groove 31, and the top of the spring 32 is A ball 33 is provided at the bottom, and a plurality of arc grooves 42 are opened at the bottom of the turntable 4 corresponding to the ball 33. The ball 33 is pressed against the inner cavity of the arc groove 42. The elastic deformation of the spring 32 is utilized to make the spring 32 drive the ball 33 to press the corresponding arc groove 42, so that the turntable 4 can be relatively fixed without the action of external force. In actual use, the rotation angle of the level is mostly forty-five degrees or ninety degrees. Therefore, the number of the mounting groove 31, the spring 32, the ball 33 and the arc groove 42 are preferably set to eight. This design replaces the traditional gear transmission, making the positioning more accurate, convenient and practical.

[0018] Specifically, the bracket 1 includes a mounting base 11, and a plurality of legs 13 are arranged at the bottom of the mounting base 11. The legs 13 support the mounting base 11. The inner cavity of the mounting base 11 is slidably connected with a slide rod 2, and the top end of the slide rod 2 is fixedly arranged at the bottom of the fixed plate 3. The slide rod 2 slides in the inner cavity of the mounting base 11, which can drive the fixed plate 3 to move longitudinally, thereby adjusting the use height of the level. A screw 12 is threadedly connected to the side wall of the mounting base 11, and the threaded end of the screw 12 is pressed against the outer wall of the slide rod 2. The design purpose is that the screw 12 can press and fix the slide rod 2, thereby locking the use height of the level.

[0019] Specifically, the outer wall of the slide bar 2 and the inner cavity of the mounting seat 11 are both designed to be rectangular, so as to limit the rotation of the slide bar 2.

[0020] Specifically, the turntable 4 is provided with an annular slideway 43 between the plurality of arc grooves 42 , and the depth of the annular slideway 43 is less than the depth of the arc groove 42 . This design can guide the rolling of the ball 33 and prevent the ball 33 from leaving the movable track.

[0021] Specifically, a plurality of mounting holes 44 are provided on the top of the turntable 4 for inserting the legs of the level, and a plurality of grooves 45 are processed on the side wall of the turntable 4. The design of the grooves 45 increases the friction of the operator's hand, making it easier for the operator to hold the turntable 4 and rotate it.

[0022] Working principle: When the support frame is in use, the legs 13 on the bracket 1 can be opened and placed in a suitable position. At this time, the level is placed on the turntable 4, and the legs of the level are inserted into the mounting holes 44 for fixing. Then, the screws 12 are screwed to separate it from the slide bar 2. At this time, the slide bar 2 can be pulled to move longitudinally, thereby adjusting the use height of the level, and the height is locked by screwing the screws 12. At this time, the level can be used to measure the object to be measured. When the direction needs to be turned, the user can directly turn the turntable 4 by holding the mounting seat 11, so that the ball 33 on the fixed plate 3 is separated from the corresponding arc groove 42 and rolls in the slideway 43. When the ball 33 overlaps and presses against other arc grooves 42, the measuring direction of the level is changed. At this time, because the ball 33 presses against the arc groove 42 again, without the action of external force, the turntable 4 and the level can be fixed after rotation, and the direction facing after rotation can be measured.
