[0037] As Figures 3 to 7 described, the present utility model discloses a threshold structure, including:

[0038] A base 1, which successively has a first card slot 11, a second card slot 12 and a clamping end 13 from the rear to the front, and the first card slot 11 and the second card slot 12 are arranged with their openings upward;

[0039] A plate body 2, which is arranged in the second card slot 12 of the base 1;

[0040] A threshold body 3, which is arranged in the first card slot 11 of the base 1, and the front end of the threshold body 3 abuts against the rear end of the plate body 2;

[0041] A card strip 4, which is clamped at the clamping end 13 of the base 1, and a first extension edge 41 is provided at the rear end of the card strip 4, and the first extension edge 41 presses on the front end of the plate body 2.

[0042] In this way, in the present utility model, by movably arranging a plate body 2 on the base 1, and respectively limiting both ends of the plate body 2 by the card strip 4 and the threshold body 3, the plate body 2 is limited and arranged in the base 1. Only by removing the threshold body 3 can the plate body 2 be easily removed, and the replacement of the plate body 2 is completed. The difficulty of replacing the plate body 2 is small, and the aesthetic degree of the threshold structure is high. Moreover, by the front end of the threshold body 3 abutting against the rear end of the plate body 2, the gap between the plate body 2 and the second card slot 12 is blocked, preventing dust and the like from accumulating in the second card slot 12, and it is also more beautiful.

[0043] In the present utility model, the base 1 is formed by extrusion molding of modified plastic, the threshold body 3 is formed by extrusion molding of modified plastic, the card strip 4 is a metal profile, and the plate body 2 can be an inorganic mineral plate or an organic plate.

[0044] Generally speaking, in order to prevent users from being tripped and for a transition connection with the flat ground, therefore, the second card slot 12 is inclined with the front end lower and the rear end higher. In this way, after the plate body 2 is arranged in the second card slot 12, the plate body 2 is also inclined as a whole to form a slope.

[0045] As Figures 3 to 5 、 Figure 7As shown in the figure, a third card slot 14 with an opening downward is provided at the lower surface of the front end of the base 1; the card strip 4 includes a first connecting edge 42, a second connecting edge 43, a third connecting edge 44, a fourth connecting edge 45 and a fifth connecting edge 46. The rear end of the first connecting edge 42 is connected to the upper end of the second connecting edge 43. The rear end of the first connecting edge 42 extends backward to form a first extension edge 41. The front end of the first connecting edge 42 is connected to the upper end of the third connecting edge 44. The lower end of the third connecting edge 44 is connected to the front end of the fourth connecting edge 45. The rear end of the fourth connecting edge 45 is connected to the lower end of the fifth connecting edge 46. A fourth card slot 47 is formed among the first connecting edge 42, the second connecting edge 43, the third connecting edge 44, the fourth connecting edge 45 and the fifth connecting edge 46. The card strip 4 is stuck at the clamping end 13 of the base 1 through the fourth card slot 47. The second connecting edge 43 of the card strip 4 is buckled in the second card slot 12, and the fifth connecting edge 46 of the card strip 4 is buckled in the third card slot 14 of the base 1.

[0046] In this way, by providing the second connecting edge 43 and the fifth connecting edge 46 on the card strip 4, the card strip 4 is completely stuck at the clamping end 13 of the base 1 to prevent the card strip 4 from coming out of the base 1. To further prevent the card strip 4 from coming out, after the card strip 4 is buckled on the base 1, the card strip 4 and the base 1 can be fixedly connected through a fastener.

[0047] Since the first extension edge 41 presses on the front end of the plate body 2, during the process of replacing the plate body 2, the first extension edge 41 may hinder the removal of the plate body 2. Therefore, in the present utility model, an upper part of the third connecting edge 44 is bent to form a groove 441, and the front end of the first connecting edge 42 extends forward to form a second extension edge 48. The second extension edge 48 is located above the groove 441. In this way, during the process of removing the plate body 2, by pressing the second extension edge 48, the first connecting edge 42, the first extension edge 41 and the second connecting edge 43 can be deformed to slightly warp upward, so as to reduce the block of the first extension edge 41 on the plate body 2 and make it easier to remove the plate body 2.

[0048] To prevent the first connecting edge 42 and the first extension edge 41 from breaking during the process of pressing the second extension edge 48, a plurality of ribs 49 are provided on the upper surfaces of the first connecting edge 42 and the first extension edge 41 to increase the strength of the first connecting edge 42 and the first extension edge 41.

[0049] Such as Figure 3 、 Figure 4 and Figure 6As shown in the figure, the threshold body 3 includes a bead 31, a plug-in portion 32, a sixth connecting edge 33, and a seventh connecting edge 34. The rear end of the sixth connecting edge 33 is connected to the front side surface of the plug-in portion 32, and the front end of the sixth connecting edge 33 is connected to the upper end of the seventh connecting edge 34. The bead 31 is arranged at the lower end of the seventh connecting edge 34. The threshold body 3 is inserted into the first card slot 11 of the base 1 through the plug-in portion 32, the seventh connecting edge 34 is buckled in the second card slot 12, and the bead 31 presses on the rear end of the plate body 2. The bead 31 is made of an elastic material. The bead 31 can be separately installed at the lower end of the seventh connecting edge 34 or integrally formed on the seventh connecting edge 34.

[0050] In order to facilitate the adjustment of the height of the threshold body 3, it further includes a nut 5, a bolt 6, and a cap 7. The plug-in portion 32 of the threshold body 3 is successively provided with a first installation groove 321 and a second installation groove 322 from top to bottom. The opening of the first installation groove 321 faces upward, and the opening of the second installation groove 322 faces downward. The first installation groove 321 and the second installation groove 322 are communicated through a channel 323. The nut 5 is installed in the second installation groove 322 in a manner that can only rotate. The head end of the bolt 6 is located in the first installation groove 321. The rod body of the bolt 6 passes through the first installation groove 321 and the channel 323 in sequence and is threadedly engaged with the nut 5 located in the second installation groove 322. The lower end of the bolt 6 passes through the second installation groove 322 and abuts against the bottom of the first card slot 11. By rotating the bolt 6, the nut 6 is driven to move up and down on the screw of the bolt 6, thereby adjusting the height of the threshold body 3 in the first card slot 11; the cap 7 is installed at the opening of the first installation groove 321 to close the first installation groove 321.

[0051] In order to increase the installation strength between the threshold body 3 and the base 1 and prevent the threshold body 3 from easily slipping out of the base 1, a tooth-shaped structure is provided on the side wall of the plug-in portion 32, and a tooth-shaped structure is provided on the side wall of the first card slot 11.

[0052] The present utility model also discloses a door frame, as Figure 1 and Figure 2 shown, which includes a door frame body 8 and the threshold structure as described above. The left and right sides of the door frame body 8 are respectively fixedly connected to the left and right sides of the base 1. By providing a threshold body 3 with adjustable height, the installation structure of the door frame body 8 and the threshold body 3 can be in place, preventing problems such as inaccurate dimensions and improper installation caused by the threshold body 3 being too high or too low, and avoiding affecting the installation effect.
