Existing doorstop devices have many shortcomings in practical applications. Their profiles are mostly made of aluminum alloy, typically machined from prefabricated ribs and then folded to form the profile. This results in a thicker, more expensive profile, and the edges are susceptible to corrosion and burrs. Therefore, it is necessary to develop a doorstop device that is simple to manufacture, low-cost, and capable of achieving a sealing effect, to address the existing problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solution of the present utility model will be further described in detail below in conjunction with specific implementation methods.

[0021] like Figures 1 to 3As shown, a profile includes a longitudinal frame 1 integrally formed from a plate, the cross section of the frame 1 is a "J"-shaped structure, and the frame 1 of the utility model is installed under a door panel (not shown) when in use. The frame 1 includes a U-shaped body 2 and a folded edge 6 arranged on both sides of the free end of the U-shaped body 2 and folded outward. Furthermore, the folded edges 6 are folded inward to form a flange 7. The length of the flange 7 is 30%-60% of the length of the folded edge 6. The connection between the folded edge 6 and the flange 7 is free of burrs and has a smooth surface, which makes it safer and more beautiful when used. At the same time, it can also prevent the edge of the folded edge 6 from rusting and affecting the use of the door panel. The folded edge 6 folded inward can also play a role in reinforcing the frame 1 as a whole. The frame 1 is provided with a plurality of fixing holes 8 that pass through the folded edge 6 and the flange 7, and the fixing holes 8 can connect the frame 1 to the bottom of the door panel. Furthermore, notches 9 are provided at both ends of the folding edge 6 close to the frame 1. The notches 9 can be adapted to the corners of the door panel when in use, so as to facilitate the installation of the frame 1 on the door panel. The shape of the notch 9 of the present invention can be selected for suitability according to the usage. Furthermore, both side walls of the U-shaped body 2 are symmetrically provided with ridges 3 protruding toward the interior of the U-shaped body 2 along the length direction of the frame 1. The ridges 3 divide the interior of the U-shaped body 2 into a first cavity 4 and a second cavity 5. The profile of the present invention is a "J"-shaped structure formed by integrally bending aluminum, aluminum alloy, iron or stainless steel plates. The processing of the ridges 3 abandons the traditional prefabricated machining method and instead adopts a stamping process to form the ridges 3. Compared with traditional profiles, the thickness of the profile of the present invention after processing is thinner, which reduces the overall weight, facilitates transportation and installation, and reduces material costs.

[0022] The present invention also provides a lifting sealing strip including the above-mentioned profile, wherein a sealing device 10 that can extend out of the U-shaped body 2 is provided inside the U-shaped body 2, and the sealing device 10 is used to seal the gap between the door panel and the ground. The sealing device 10 includes a rod body 11 and a sealing strip 12 connected to the rod body 11. The length of the rod body 11 and the sealing strip 12 is consistent with the length of the frame body 1. The sealing strip 12 of the present invention can be a rubber strip. The sealing strip 12 is provided on one side of the rod body 11, and two bendable elastic strips 13 are provided on the side of the rod body 11 away from the sealing strip 12. The end of each elastic strip 13 is provided with a connecting block 14, and the two connecting blocks 14 are respectively provided at positions close to the two end portions of the frame body 1. One of the connecting blocks 14 is fixed to the frame 1, and the other connecting block 14 is connected to the push rod 15 and is not fixed to the frame 1. One end of the push rod 15 extends out of the frame 1 to squeeze the push rod 8 when the door panel is closed, so that the elastic strip 13 bends and the sealing device 3 is pushed out of the U-shaped body 2 to seal the gap between the door panel and the ground.

[0023] Furthermore, a connecting block 14 and a push rod 15 are disposed within the first cavity 4. A connecting hole 16 is provided in the frame 1, allowing the connecting block 14 to be connected to the frame 1 via bolts. A step 17 is provided near the protrusion 3 on the connecting block 14, which mates with the protrusion 3. During use, the movable connecting block 14 can move within the first cavity 4 using the step 17 and the protrusion 3. The rod 11 and the sealing strip 12 are disposed within the second cavity.

[0024] When the utility model is in use, the push rod 15 is squeezed, and the push rod 15 drives the movable connecting block 14 to squeeze the elastic strip 13. The elastic strip 13 is bent under the force, and the rod body 11 connected to the elastic strip 13 and the sealing strip 12 are squeezed out of the second cavity 5, thereby sealing the gap between the door panel and the ground.

[0025] The profile of this utility model is an "X"-shaped structure formed by integrally bending aluminum, aluminum alloy, iron, or stainless steel sheets. Its convex strips are stamped to form a retaining structure. This profile is simple to manufacture and low in cost. The lifting seal strip of this utility model incorporates an extendable sealing device 10 within the U-shaped body 2. When the door panel is closed, the push rod 15 and the elastic strip 13 cooperate to effectively push the sealing device 10 out, tightly fitting the gap between the door panel and the floor, thereby achieving a seal. The automatic extension and retraction of the sealing device 10 improves ease of use and efficiency.
