Description

Technical Field

[0001] The utility model belongs to the technical field of floor drain slope finding, and particularly relates to a mechanical floor drain slope finding tool. Background Technique

[0002] At present, manual slope finding is adopted for floor drain slope finding during construction. However, due to problems such as numerous steps, waste of labor, impact on the construction period, slope errors, and inconvenient construction in some areas in manual slope finding, the construction process is relatively backward. Against this background, a mechanical floor drain slope finding tool has emerged. It adopts a pre-buried method and realizes automatic slope finding by adjusting the slope through a mechanical structure, making it easier for workers to understand and operate, facilitating operation, construction, and having higher economy.

[0003] The traditional floor drain slope finding method determines the slope finding range and slope line position by manual line laying before the fine stone concrete of the floor slab is poured. Manual line laying is prone to measurement errors. The traditional floor drain slope finding method conducts manual slope finding and finishing before the concrete begins to set, which is prone to quality defects in finishing. In view of this, we propose a mechanical floor drain slope finding tool. Content of the Utility Model

[0004] The purpose of the utility model is to provide a mechanical floor drain slope finding tool to solve the problems raised in the above background technique.

[0005] In view of this, the utility model provides a mechanical floor drain slope finding tool, including:

[0006] A base, a fixed block is fixedly installed inside the base, a rotating rod is rotatably installed on one side of the fixed block and above the base, sliding grooves are symmetrically opened at the bottom of the base, sliding plates are slidably installed in the sliding grooves, and rubber pads are fixedly installed on the sides of the two sliding plates away from each other;

[0007] A driving component, which is located inside the base and is used to drive the two sliding plates to approach or move away from each other;

[0008] An angle line, which is engraved on one side of the fixed block and on one side of the rotating rod. An observation groove is opened inside the rotating rod and on one side of the angle line, a pointer is fixedly installed on the inner wall of the observation groove, and a spirit level is fixedly installed on the top of the base and on one side of the fixed block;

[0009] A power component, which is located inside the fixed block and is used to drive the rotating rod to rotate.

[0010] In this technical solution, through the provided driving component, the driving component will drive two sliding plates to move respectively, causing the two sliding plates to move away from each other until the rubber pads on the sliding plates abut against the inner wall of the floor drain. At this time, under the action of friction, the two rubber pads can pre-fix the base. Subsequently, the user can observe the spirit level bubble and then adjust the position of the base to make the base in a horizontal position. Then, the driving component drives the two sliding plates to move away from each other. The two sliding plates moving away from each other will respectively squeeze the two rubber pads, causing the two rubber pads to deform. At this time, the base can be horizontally fixed on the floor drain, ensuring that it is convenient for the user to fix the base and ensuring that the base can maintain a horizontal state after being fixed;

[0011] Through the provided power component, when the power component is driven, the power component will drive the rotating rod to rotate. At the same time, the user can observe the position of the pointer on the angle line through the observation slot, so as to accurately control the rotation angle of the rotating rod. At this time, the user can slope the concrete floor and finish it, ensuring that when the user slopes the floor drain, it is not necessary to manually lay out lines, thereby improving the slope accuracy and avoiding errors.

[0012] In the above technical solution, further, the driving component includes:

[0013] Two threaded rods, the two threaded rods are respectively rotatably installed in two sliding grooves. One end of each of the two threaded rods penetrates through the two sliding plates respectively. A rectangular groove is formed in the base and located between the two sliding grooves.

Two first bevel gears are meshingly installed on both sides of the second bevel gear and within the rectangular groove. One end of each of the two first bevel gears penetrates through both sides of the rectangular groove and is coaxially connected to the corresponding threaded rod. The top end of the second bevel gear is fixedly installed with a rotating handle, and the top end of the rotating handle extends to the outside.

[0014] In this technical solution, rotate the rotating handle. The rotation of the rotating handle will drive the second bevel gear to rotate. Under the action of meshing, the rotation of the second bevel gear will drive the two first bevel gears to rotate. The rotation of the two first bevel gears will respectively drive the two threaded rods to rotate. Under the action of the thread, the rotation of the two threaded rods will respectively drive the two sliding plates to move, so that the two sliding plates move away from each other until the rubber pads on the sliding plates abut against the inner wall of the floor drain. At this time, under the action of friction, the two rubber pads can pre-fix the base. Subsequently, the operator can observe the spirit level bubble, thereby adjusting the position of the base, and can adjust the base to a horizontal position. Then the operator can rotate the rotating handle again, so that the two sliding plates move away from each other. The two sliding plates moving away from each other will respectively squeeze the two rubber pads, causing the two rubber pads to deform. At this time, the base can be horizontally fixed on the floor drain, ensuring that it is convenient for the operator to fix the base and ensuring that the base can remain horizontal after being fixed.

[0015] In the above technical solution, further, the threaded rod is threadedly connected to the sliding plate, the first bevel gear is rotatably connected to the rectangular groove, and the rotating handle is rotatably connected to the base.

The output end of the motor penetrates through one side of the installation groove and extends into the rotating groove and is coaxially connected to the worm.

[0019] In this technical solution, start the motor. The output shaft of the motor will drive the worm to rotate. Under the action of meshing, the rotation of the worm will drive the worm gear to rotate. The rotation of the worm gear will drive the rotating rod to rotate. At the same time, the operator can observe the position of the pointer on the angle line through the observation groove, thereby accurately controlling the rotation angle of the rotating rod. At this time, the operator can slope the concrete floor and finish it, ensuring that when the operator slopes the floor drain, it is not necessary to use manual line laying by the operator, thereby improving the slope accuracy and not generating errors.
