Description

Technical Field

[0001] This utility model relates to the field of self-leveling floor construction technology, specifically to a device for self-leveling floor construction. Background Technology

[0002] Self-leveling flooring is a surface layer formed by spreading materials with self-leveling or slightly assisted leveling functions on a base layer after on-site mixing. Common types of self-leveling flooring include clay-based self-leveling flooring, resin-based self-leveling flooring, and resin-cement composite mortar self-leveling flooring. During the construction of self-leveling flooring, a notched squeegee and a flat squeegee are needed to scrape away any flowing material to ensure the quality of the flooring.

[0003] The existing flat screed and notched screed for floor construction are two separate structures. When a flat screed or a notched screed is needed, two screed structures need to be carried, which makes it inconvenient for construction workers to operate. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a device for constructing self-leveling flooring. Through an outer frame, a sliding groove, a mounting bracket, limiting protrusions, limiting grooves, spring pins, pins, limiting posts, a tension spring, a horizontal shaft, and a neodymium magnet, a flat scraper and a toothed scraper are fixed to the mounting bracket. When one tool is needed, the pin on the corresponding spring pin of the mounting bracket is rotated 90 degrees. The horizontal shaft and the limiting post remain perpendicular. Under the action of the tension spring, the horizontal shaft pushes the pin towards the neodymium magnet, which then attracts and fixes the horizontal shaft. This causes the mounting bracket to be pushed out of the sliding groove by the pin, allowing construction workers to use either the toothed scraper or the flat scraper, facilitating construction operations and effectively solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-leveling flooring construction device, comprising an outer frame, two sliding grooves provided on the inner side of the outer frame, a limiting protrusion installed on the top side of the inner sliding groove, an installation frame installed on the outer side of the limiting protrusion, a limiting groove machined on the installation frame corresponding to the position of the limiting protrusion, a flat scraper installed on the installation frame in the upper sliding groove, a toothed scraper installed on the installation frame in the lower sliding groove, a spring pin welded to one side of the outer frame, a pin inserted into the spring pin, a tension spring sleeved on the outer side of the pin, limiting posts symmetrically welded to the upper side of the spring pin, a horizontal shaft passing through the end of the pin near the outer frame, and a neodymium magnet installed on the side of the spring pin near the outer frame.

[0006] Furthermore, a rod sleeve is connected to the upper side of the outer frame via a hinge, the horizontal shaft is welded to the pin, and the neodymium magnet is glued to the side of the spring pin.

[0007] Furthermore, the mounting bracket is connected to the flat scraper by screws, and the mounting bracket is connected to the toothed scraper by screws.

[0008] Furthermore, the mounting bracket is connected to the outer frame via the limiting groove and the limiting protrusion, and four spring pins are installed on the outer frame.

[0009] Furthermore, the limiting protrusion is welded to the outer frame, and the end of the pin is connected to the mounting bracket via a rotating disk.

[0010] Furthermore, a groove is machined at the center of the limiting post, and the limiting posts are symmetrically arranged on both sides of the pin.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the setting of an outer frame, a sliding groove, a mounting bracket, a limiting protrusion, a limiting groove, a spring pin, a pin, a limiting post, a tension spring, a horizontal shaft, and a neodymium magnet, fixes the flat scraper and the toothed scraper on the mounting bracket. When one of the tools is needed, the pin on the spring pin connected to the mounting bracket is rotated 90 degrees. The horizontal shaft and the limiting post are both kept perpendicular. Under the action of the tension spring, the horizontal shaft pushes the pin towards the neodymium magnet. The horizontal shaft is attracted and fixed by the neodymium magnet, so that the mounting bracket is pushed out of the sliding groove by the pin. This allows the construction personnel to use either the toothed scraper or the flat scraper, making the construction operation more convenient. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1-4 This embodiment provides a technical solution: a self-leveling flooring construction device, including an outer frame 2, with two sliding grooves 8 on the inner side of the outer frame 2, a limiting protrusion 9 installed on the inner top side of the sliding groove 8, and an installation frame 4 installed on the outer side of the limiting protrusion 9. The installation frame 4 is machined with a limiting groove 7 corresponding to the position of the limiting protrusion 9. A flat scraper 5 is installed on the installation frame 4 in the upper sliding groove 8, and a toothed scraper 6 is installed on the installation frame 4 in the lower sliding groove 8. A spring pin 3 is welded to one side of the outer frame 2, and a pin rod 10 is inserted into the spring pin 3. A tension spring 11 is sleeved on the outer side of the pin rod 10. Limiting posts 12 are symmetrically welded to the upper side of the spring pin 3. A horizontal shaft 13 passes through the end of the pin rod 10 near the outer frame 2. A neodymium magnet 14 is installed on the side of the spring pin 3 near the outer frame 2.

[0020] like Figure 1-4 As shown, the neodymium magnet 14 can stably attract and fix the horizontal shaft 13 to the vertical side wall of the spring pin 3, preventing the flat scraper 5 or the toothed scraper 6 from moving along the pin 10.

[0021] The upper side of the outer frame 2 is connected to the rod sleeve 1 by a hinge, the horizontal shaft 13 is welded to the pin 10, and the neodymium magnet 14 is glued to the side of the spring pin 3.

[0022] like Figure 1-4 As shown, the limiting post 12 can limit and lock the horizontal axis 13, thereby causing the pin 10 to be pulled back and retracted, and thus causing the mounting bracket 4 to enter the inner side of the outer frame 2, so that the toothed scraper 6 or the flat scraper 5 can be stored in the outer frame 2.

[0023] Mounting bracket 4 is connected to flat scraper 5 by screws, and mounting bracket 4 is connected to toothed scraper 6 by screws.

[0024] Mounting bracket 4 is connected to outer frame 2 via limiting groove 7 and limiting protrusion 9. There are four spring pins 3 installed on outer frame 2.

[0025] like Figure 1 , 2 As shown in Figure 4, the limiting groove 7 can limit and secure the limiting protrusion 9, so that the limiting protrusion 9 can move stably, thereby allowing the mounting frame 4 to slide stably, ensuring that the flat scraper 5 and the toothed scraper 6 scrape the flowing material on the ground.

[0026] The limiting protrusion 9 is welded to the outer frame 2, and the end of the pin 10 is connected to the mounting bracket 4 through a rotating disk.

[0027] The center of the limiting post 12 is machined with a groove, and the limiting post 12 is symmetrically arranged on both sides of the pin 10.

[0028] The working principle of the self-leveling flooring construction device provided by this utility model is as follows: Figures 1-4 As shown, during use, the rod sleeve 1 is connected and fixed to the grip. The angle between the rod sleeve 1 and the outer frame 2 is adjusted by the hinge structure at the lower end of the rod sleeve 1. When the toothed scraper 6 needs to be used, the pin 10 connected to the spring pin 3 on the toothed scraper 6 is rotated 90 degrees, causing the horizontal shaft 13, which is vertically fixed on the limiting post 12, to rotate to a state parallel to the limiting post 12. This allows the horizontal shaft 13 to be pushed from between the two limiting posts 12 towards the neodymium magnet 14 under the spring force of the tension spring 11, causing the horizontal shaft 13 to be attracted to the neodymium magnet 14. The mounting bracket 4 is pushed out of the slide groove 8, which in turn pushes the toothed scraper 6 out of the outer frame 2. When the toothed scraper 6 is not needed, the pin 10 is pulled away from the outer frame 2. When the horizontal axis 13 moves to the limiting post 12, it is then rotated 90 degrees so that the horizontal axis 13 and the limiting post 12 are both perpendicular. This allows the horizontal axis 13 to pass between the two limiting posts 12. After passing through, the pin 10 is rotated 90 degrees so that the horizontal axis 13 can be locked onto the limiting post 12. This allows the pin 10 to drive the mounting bracket 4 into the slide groove 8 of the outer frame 2.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
