Abstract
Description
Technical Field
[0001] This utility model belongs to the field of home decoration tools technology, and relates to a pressing structure of a crack cleaning machine. Background Technology
[0002] After home renovation is completed and floor tiles are laid, many households will apply grout sealant to the gaps between the tiles. Before doing so, the gaps between the tiles can be cut. To facilitate this process, handheld grout sealant machines have been designed.
[0003] Existing seam cleaning machines cannot guarantee uniform seam depth during the cutting process, which can easily lead to uneven seam depth at different locations during operation. Therefore, it is necessary to develop a device that can uniformly clean seam depth. Utility Model Content
[0004] The purpose of this invention is to address the problem that existing seam cleaning machines cannot control the uniform cutting depth, and to propose a pressing structure for the seam cleaning machine, which is installed on the body of the seam cleaning machine.
[0005] The objective of this utility model can be achieved through the following technical solutions:
[0006] A pressing structure for a seam cleaning machine is characterized by comprising a base and a pressing component disposed on the base. One end of the seam cleaning machine body is hinged to the base, and the pressing component is located at the other end of the seam cleaning machine body. The pressing component includes a guide block, a guide piece, and a limiting body. The guide piece and the limiting body are fixedly and offset from each other on the base. An arc-shaped guide opening is provided on the guide piece. The guide block is fixed on the seam cleaning machine body. A guide body is provided on the guide block and slidably embedded in the arc-shaped guide opening. The limiting body is disposed below the guide block to limit the lowest position of the guide block's descent.
[0007] In the aforementioned pressing structure of a seam cleaning machine, the limiting body includes a fixed body and a rotating body. The fixed body is fixedly mounted on the base, and a threaded hole is provided on the top of the fixed body. The rotating body is provided with a threaded body at the bottom, and the threaded body is mounted on the fixed body by rotating through the thread.
[0008] In the aforementioned pressing structure of a seam cleaning machine, the guide block includes an inner guide sub-block fixed on the body of the seam cleaning machine and an outer guide sub-block fixed on the inner guide sub-block by bolts. The guide body is disposed on the inner guide sub-block, and the inner and outer guide sub-blocks are attached to the inner and outer sides of the guide plate.
[0009] In the pressing structure of the above-mentioned seam cleaning machine, an insert is fixedly provided at the bottom of the arc-shaped guide opening of the guide plate, and a spring with a spring-like tendency to spring open is provided between the insert and the guide.
[0010] Compared with existing technologies, this pressing structure can adjust the slit depth, and the slit depth can be adjusted according to different usage requirements, ensuring the uniformity of the slit cutting process. Attached Figure Description

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0018] like Figures 1-5 As shown, the pressing structure of this sewing machine includes a base 1 and a pressing component mounted on the base. One end of the sewing machine body 2 is hinged to the base, and the pressing component is located at the other end of the sewing machine body. The pressing component includes a guide block 3, a guide piece 4, and a limiting body 5. The guide piece and the limiting body are fixed to the base in a staggered manner. The guide piece has an arc-shaped guide opening 6 (located on the rotation path of the sewing machine body around the base). The guide block is fixed to the sewing machine body, and the guide block has a guide body 7 that slides into the arc-shaped guide opening. The limiting body is located below the guide block to limit the lowest position of the guide block's descent.
[0019] like Figure 4 and Figure 5 As shown, the limiting body includes a fixed body 8 and a rotating body 9. The fixed body is fixedly mounted on the base, and a threaded hole is provided on the top of the fixed body. The rotating body is provided with a threaded body at the bottom, and the threaded body is mounted on the fixed body by rotating through the thread.
[0020] like Figure 2 and Figure 3 As shown, the guide block includes an inner guide sub-block 10 fixed on the body of the sewing machine and an outer guide sub-block 11 fixed on the inner guide sub-block by bolts. The guide body is set on the inner guide sub-block, and the inner and outer guide sub-blocks are attached to the inner and outer sides of the guide plate.
[0021] like Figures 1-5 As shown, an insert 12 is fixedly provided at the bottom of the arc-shaped guide opening of the guide piece, and a spring 13 with a spring-like tendency to spring open is provided between the insert and the guide.
[0022] During use, adjust the height of the rotating body on the fixed body according to the actual usage environment where the seam cleaning machine needs to press down the seam. Then, hold the seam cleaning machine and press it down while cutting the seam. The main body of the seam cleaning machine will flip around the arc-shaped guide opening and the hinge position relative to the base. With a little force, the main body of the seam cleaning machine will be pressed down to the bottom until the guide block contacts the limit body and is restricted by it. The restricted pressing height is the required cutting depth. As long as it is pressed down to the bottom, the cutting depth will be a constant dimension.
[0023] Because the height of the limiting body can be adjusted at will, it can adapt to various cutting depth requirements.
[0024] It should be understood that in the claims and description of this utility model, all instances of "comprising..." should be understood as having an open meaning, that is, their meaning is equivalent to "containing at least...", and should not be understood as having a closed meaning, that is, their meaning should not be understood as "containing only...".
[0025] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
