Description

Technical Field

[0001] The utility model belongs to the technical field of floors, and in particular relates to a floor and a threshold stone transition strip. Background Art

[0002] After the floor is laid, there is often a gap between the floor and the door sill. During the use of the floor, it is easy for dust under the floor to be discharged to the top of the floor through the gap. At the same time, the gap between the floor and the door sill is not aesthetically pleasing. Therefore, the gap is often sealed with beautiful seams or caulking strips on the market to improve the aesthetics while preventing dust under the floor from being discharged from the gap.

[0003] The utility model with application number 202321036220.0 discloses a T-shaped rubber floor trim strip, comprising a trim strip body and a trim wedge portion, wherein the trim wedge portion is arranged at the bottom of the trim strip body to form a "T"-shaped structure; a groove body matching the floor is provided at the intersection of the trim strip body and the trim wedge portion. The trim strip can be used to be inserted into the gap between the floor and the door sill to close the gap, but the trim strip is fixed in the gap by glue, which has poor stability and the transition strip is easy to fall off from the gap.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings.

[0022] A transition strip for a floor and a door sill comprises a T-shaped caulking strip 1, a support plate 2 and a support assembly 3. The support plate 2 is swingably mounted at the bottom of the T-shaped caulking strip 1. The support assembly 3 is connected to the support plate 2 and is used to drive the support plate 2 to be expanded. The T-shaped caulking strip 1 is first inserted into a gap between the floor and the door sill, and then the support plate 2 is expanded by the support assembly 3 so that the support plate 2 abuts against the lower end surface of the floor, thereby effectively preventing the T-shaped caulking strip 1 from falling off the gap and improving the stability of the transition strip.

[0023] The T-shaped caulking strip 1 includes a T-shaped plug-in portion 1-5 and a baffle portion 1-6, the support plate 2 is installed on the plug-in portion 1-5, the baffle portion 1-6 is arranged above the gap to shield the gap, and the plug-in portion 1-5 is used to be plugged into the gap, so that the support plate 2 installed on the plug-in portion 1-5 can be easily abutted against the lower end surface of the floor.

[0024] The baffle portion 1-6 is arranged in an arc shape. When installing the transition strip, the baffle portion 1-6 is pressed downward so that the baffle portion 1-6 is deformed under force. When the transition strip is installed, the two side edges of the baffle portion 1-6 abut against the floor and the door sill, providing an upward force to the plug-in portion 1-5, so that the support plate 2 can stably abut against the lower end surface of the floor, thereby preventing the transition strip from shaking after installation.

[0025] The spreading component 3 is arranged through the plug-in portion 1-5 and the baffle portion 1-6, so that the spreading component 3 can be used to drive the support plate 2 to rise, fall and spread.

[0026] A mounting groove 1-2 is provided on the plug-in portion 1-5. The mounting groove 1-2 includes two side walls and an opening guide surface 1-1. The opening guide surface 1-1 is inclined relative to the vertical surface. The opening direction of the support plate 2 is guided by the opening guide surface 1-1, so as to stably open the support plate 2. A limiting surface 1-3 is provided on the opening guide surface 1-1. The limiting surface 1-3 is adapted to the support plate 2, that is, during the opening process of the support plate 2, the opening angle of the support plate 2 is limited by the limiting surface 1-3. Waist-shaped grooves 1-4 are provided on the side walls of the mounting groove 1-2. The support plate 2 can be slidably installed in the mounting groove 1-2 through the waist-shaped grooves 1-4, so as to facilitate the up and down adjustment of the support plate 2.

[0027] The support assembly 3 includes a connecting shaft 3-1 and an adjusting screw 3-2. The support plate 2 is rotatably mounted on the connecting shaft 3-1. Both ends of the connecting shaft 3-1 extend into the waist-shaped groove 1-4 respectively, that is, the support plate 2 is installed on the T-shaped caulking strip 1 through the connecting shaft 3-1. The adjusting screw 3-2 is installed in the T-shaped caulking strip 1 through a thread and is rotatably connected to the connecting shaft 3-1. The connecting shaft 3-1 is adjusted up and down by the adjusting screw 3-2. A groove 2-1 is provided on the support plate 2, and the groove 2-1 is adapted to the adjusting screw 3-2 to prevent the adjusting screw 3-2 from interfering with the support plate 2.

[0028] As a preferred embodiment, a slope is provided on the support plate 2. When the support plate 2 is folded, the slope fits with the support guide surface 1-1, so that the support plate 2 can be completely received in the installation groove 1-2, thereby preventing the support plate 2 from affecting the insertion of the plug-in part 1-5 into the gap.

[0029] The installation method of this transition strip is as follows;

[0030] (1) First, turn the adjusting screw 3-2 to adjust the support plate 2 to the lowest end of the plug-in portion 1-5, and store the support plate 2 in the installation groove 1-2;

[0031] (2) Insert the plug-in parts 1-5 into the gap;

[0032] (3) Press the baffle portion 1-6 downward, and then turn the adjusting screw 3-2 to adjust the support plate 2 upward. Since the support plate 2 is adjusted to the lowest end of the plug-in portion 1-5, and the height of the plug-in portion 1-5 is at least greater than the sum of the thickness of the floor and the height of the support plate 2, when the support plate 2 is adjusted upward, the support plate 2 is stretched open by the stretching guide surface 1-1. After the support plate 2 is stretched open, it abuts against the limiting surface 1-3, so that the support plate 2 is parallel to the floor surface. By further turning the adjusting screw 3-2, the support plate 2 abuts against the lower end surface of the floor.

[0033] (4) Fill the through hole of the baffle portion 1-6 for mounting the adjusting screw 3-2 with a filler.
