[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides a technical solution: a flame-retardant EPDM rubber strip, comprising a rubber body 1, with positioning blocks 2 movably connected to both sides of the rear end face of the rubber body 1, flame-retardant strips 3 and connecting seats 5 respectively provided at the upper and lower ends of the rubber body 1, a magnetic strip 4 fixedly connected to the top of the flame-retardant strip 3, and reinforcing strips 6 provided on both sides of the connecting seat 5, with reinforcing barbs 11 provided at the top of the reinforcing strips 6. The rubber body 1, flame-retardant strips 3, and connecting seats 5 are all integral structures, with the inner side of the flame-retardant strip 3... A first buffer hole 9 is provided. Below the magnetic strip 4, on the top surface of the flame-retardant strip 3, is an installation groove. The bottom end of the magnetic strip 4 is inserted into the inner side of the installation groove. The EPDM rubber strip can then be pulled out by sliding the two positioning blocks 2, facilitating its connection to doors and windows. Subsequently, it is fixedly connected to the doors and windows via the bolt hole 7 in the center of the positioning block 2 and the connecting seat 5, along with the reinforcing strip 6. This effectively prevents the traditional method of connecting rubber strips to doors and windows with glue, where the rubber strip easily falls off when the environment is too hot.

[0024] Please see Figures 2-3 In this embodiment, a bolt hole 7 is provided at the center of the positioning block 2. A slider 12 is provided at the bottom of the positioning block 2 opposite to the colloid body 1. The positioning block 2 and the slider 12 are an integral structure. A groove 8 is provided at one end of the slider 12 at the rear end face of the colloid body 1. One end of the slider 12 extends to the inside of the groove 8. The positioning block 2 is movably connected to the colloid body 1 through the slider 12, thereby sliding the two positioning blocks 2 to both ends of the EPDM rubber strip, so that the two positioning blocks 2 make the EPDM rubber strip straight, which is convenient for the staff to install the EPDM rubber strip later.

[0025] Please see Figures 4-5 Both the upper and lower ends of the inner wall of the connecting seat 5 are provided with buffer grooves 13. The diameters of the two buffer grooves 13 are different. A reinforcing rib 10 is provided on the inner side of one of the buffer grooves 13. The reinforcing rib 10 is an integral structure with one of the buffer grooves 13. The reinforcing rib 10 is in the shape of an inverted V. The EPDM rubber strip is buffered and reset through the reinforcing rib 10.

[0026] When the EPDM rubber strip is connected to the door or window, the two positioning blocks 2 are slid to both ends of the EPDM rubber strip to straighten it, making it easier to install. Then, it is fixed to the door or window through the bolt hole 7 in the center of the positioning block 2 and the connecting seat 5 in conjunction with the reinforcing strip 6. This effectively prevents the rubber strip from falling off when the environment is too hot, which is a common problem with traditional rubber strips connected to doors and windows with glue. A magnetic strip 4 is provided at the top of the flame-retardant strip 3, which allows the EPDM rubber strip to adhere to the door or window shell when the user is not using the door or window. Buffer grooves 13 are provided at both the upper and lower ends of the inner wall of the connecting seat 5. One of the buffer grooves 13 has a reinforcing rib 10 on its inner side. When the EPDM rubber strip is subjected to force, the reinforcing rib 10 cushions and resets the EPDM rubber strip.

[0027] Through the above steps, the EPDM rubber strip can be straightened by sliding the two positioning blocks 2, which facilitates the installation of the EPDM rubber strip with doors and windows. Then, it is fixed to the door and window through the bolt hole 7 in the center of the positioning block 2 and the connecting seat 5 in conjunction with the reinforcing strip 6. This effectively prevents the traditional rubber strip from being connected to the door and window with glue, which is prone to falling off when the environment is too hot. This solves the problem that the existing EPDM rubber strip is prone to bending during use and installation, and is more likely to stick to the door. Moreover, under high temperature conditions, the glue is prone to melting, and the EPDM rubber strip may fall off.
