Abstract
Description
Technical Field
[0001] This utility model relates to the field of cement floor construction technology, specifically a lightweight cement floor construction device. Background Technology
[0002] After the concrete is poured, construction machinery is needed to level the cement floor to ensure the quality of the floor later.
[0003] During the construction of cement floors, cement floor construction equipment is needed to smooth the cement surface. Generally, this is achieved by using a support rod to push and pull an aluminum trowel. This method has a simple structure, but in actual use, the trowel angle varies due to the different distances of the aluminum trowel, resulting in a poor troweling effect. Therefore, it is necessary to design and modify the lightweight cement floor construction equipment to effectively prevent the phenomenon of poor troweling effect caused by the inconvenience of angle adjustment. Utility Model Content
[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a lightweight cement floor construction device with the advantage of easy angle adjustment. This solves the problem that during cement floor construction, a cement floor construction device is needed to smooth the cement surface, which is generally achieved by using a support rod to push and pull an aluminum trowel plate. Although this method has a simple structure, in actual use, the smoothing angle varies due to the different distances of the aluminum trowel plate, resulting in poor smoothing effect.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a lightweight cement floor construction device, comprising a mounting base, a toothed groove on the front side of the mounting base, a first annular groove on the front side of the mounting base, a spring fixedly connected inside the first annular groove, a gear on the front side of the mounting base meshing with the toothed groove, a second annular groove on the back side of the gear, the front side of the spring fitting against the front side of the inner wall of the second annular groove, through openings fixedly connected to the surfaces of the mounting base and the gear, bolts movably connected inside the through openings, the bolts fitting against the mounting base, a wing nut threaded onto the surface of the bolts, the wing nut fitting against the gear, a mounting bracket fixedly connected to the surface of the gear, and a sleeve fixedly connected to the right side of the mounting bracket.
[0006] As a preferred embodiment of this invention, the surface of the mounting base is provided with four mounting openings.
[0007] As a preferred embodiment of this invention, the surface of the mounting bracket is fixedly connected with a reinforcing frame, and the number of the reinforcing frames is two.
[0008] As a preferred embodiment of this utility model, the surface of the sleeve is provided with two through holes, and a U-shaped elastic clip is movably connected inside the through hole.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] 1. This utility model employs a mechanism where, when the operator needs to adjust the angle of the sleeve, and consequently the angle of the support rod and the aluminum trowel plate, the operator can loosen the wing nut. At this time, under the action of the spring, the spring pushes the gear forward, disengaging it from the toothed groove. The operator can then rotate the mounting bracket and the gear to adjust the angle of the sleeve. When the operator has adjusted the sleeve to the appropriate angle, the operator rotates the wing nut in the opposite direction, causing the wing nut and the gear to move backward. At this time, the gear re-engages with the toothed groove, locking the gear and thus locking the angle of the mounting bracket and the sleeve. This device uses gear engagement with the toothed groove to adjust the angle, allowing for multiple angle adjustments. The spring mechanism allows the gear to be moved forward and reset when the wing nut is loosened, separating it from the toothed groove, thus allowing rotation to adjust the angle of the gear and the mounting bracket. This device has the advantage of facilitating angle adjustment.
[0011] 2. With the installation opening, the operator can use screws to install the mounting base in a preset position. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] like Figures 1 to 4 As shown, a lightweight cement flooring construction device includes a mounting base 1. The front of the mounting base 1 has a toothed groove 2 and a first annular groove 14. A spring 10 is fixedly connected inside the first annular groove 14. A gear 3 is provided on the front of the mounting base 1, meshing with the toothed groove 2. A second annular groove 15 is provided on the back of the gear 3. The front of the spring 10 is in contact with the front of the inner wall of the second annular groove 15. Both the surface of the mounting base 1 and the surface of the gear 3 are fixedly connected to a through-hole 4. A bolt 5 is movably connected inside the through-hole 4, fitting against the mounting base 1. A wing nut 6 is threaded onto the surface of the bolt 5, fitting against the gear 3. A mounting bracket 7 is fixedly connected to the surface of the gear 3, and a sleeve 8 is fixedly connected to the right side of the mounting bracket 7.
[0019] refer to Figure 1 and Figure 2 The surface of the mounting base 1 has four mounting openings 9.
[0020] As a technical optimization of this utility model, by setting the installation opening 9, the operator can use screws to install the mounting base 1 in a preset position.
[0021] refer to Figures 1 to 4 The surface of the mounting bracket 7 is fixedly connected with two reinforcing brackets 13.
[0022] As a technical optimization of this utility model, the stability of the mounting frame 7 can be improved by setting the reinforcing frame 13.
[0023] refer to Figures 1 to 3 The sleeve 8 has two through holes 11 on its surface. A U-shaped elastic clip 12 is movably connected inside the through hole 11.
[0024] As a technical optimization of this utility model, by setting the through hole 11 and the U-shaped elastic clip 12, the operator can put the support rod on the surface of the sleeve 8. The surface of the support rod also has two clip interfaces. When the two clip interfaces are aligned with the two through holes 11 respectively, the U-shaped elastic clip 12 passes through the clip interfaces, thereby locking the position of the support rod. The right end of the support rod is fixed with an aluminum trowel plate.
[0025] The working principle and usage process of this utility model are as follows: When the operator needs to adjust the angle of the sleeve 8 and thus the angle of the support rod and the aluminum trowel plate, the operator can loosen the wing nut 6. At this time, under the action of the spring 10, the spring 10 pushes the gear 3 forward, so that the gear 3 disengages from the toothed groove 2. Then the operator can rotate the mounting bracket 7 and the gear 3 to adjust the angle of the sleeve 8. When the operator adjusts the sleeve 8 to the appropriate angle, the operator rotates the wing nut 6 in the opposite direction, so that the wing nut 6 and the gear 3 move backward. At this time, the gear 3 re-engages with the toothed groove 2, thereby locking the gear 3 and locking the angle of the mounting bracket 7 and the sleeve 8.
