[0027] Please refer to Figures 1 to 3 , now the KS6319 sealing strip provided by the utility model will be described.

[0028] The KS6319 sealing strip comprises a fixed part 1, a pressure bearing part 2 and a supporting part 3; the pressure bearing part 2 is fixedly connected with the fixed part 1, the supporting part 3 is fixedly connected with the fixed part 1, and the pressure bearing part 2 and the supporting part 3 are arranged on the two sides of the fixed part 1; the pressure bearing part 2 is arranged on the fixed part 1 in an inclined manner, the supporting part 3 is further provided with a bending part 4 at an end away from the fixed part 1, the top surface of the bending part 4 is arranged at an angle with the fixed part 1, and the pressure bearing part 2 is arranged correspondingly with the bending part 4; the fixed part 1, the pressure bearing part 2, the supporting part 3 and the bending part 4 form a containing cavity 11, and a gap 12 is arranged between the pressure bearing part 2 and the bending part 4, and the gap 12 is in communication with the containing cavity 11.

[0029] Compared with the prior art, the KS6319 sealing strip is arranged between the door leaf 102 and the door frame door strip 101, and the supporting part 3 and the bending part 4 are arranged between the door leaf 102 and the door frame vertical stand 100; when the door leaf 102 is closed, the KS6319 sealing strip is extruded, the pressure bearing part 2 is extruded to one side of the fixed part 1, and the bending part 4 is extruded to one side of the supporting part 3, so as to close the gap between the door leaf 102 and the door frame door strip 101, and the gap is closed, thereby achieving the effects of sound insulation, fire prevention, smoke prevention and the like, and solving the technical problem that the sealing strip in the prior art can only seal the gap between the door frame door strip 101 and the door leaf 102, and cannot simultaneously seal the gap between the door frame vertical stand 100 and the door leaf 102.

[0030] The outer side of the fixed part 1 and the outer side of the supporting part 3 are both provided with an adhesive 5. The adhesive 5 is used to respectively bond and fix the KS6319 sealing strip with the door frame door strip 101 and the door frame vertical stand 100, so as to prevent the KS6319 sealing strip from falling off.

[0031] In some embodiments, the thickness of the pressure bearing part 2 is greater than the thickness of the bending part 4.

[0032] In other embodiments, the thickness of the pressure bearing part 2 is less than or equal to the thickness of the bending part 4.

[0033] On the basis of the above embodiments, the supporting part 3 has a structure with gradually shrinking thickness, and the thickness of one end of the supporting part 3 close to the fixed part 1 is greater than the thickness of the other end of the supporting part 3 away from the fixed part 1. This arrangement can make the one end of the supporting part 3 away from the fixed part 1 have better freedom of movement, while making the connection between the supporting part 3 and the fixed part 1 more firm, so as to avoid the fracture of the connection between the supporting part 3 and the fixed part 1 due to stress concentration.

[0034] Specifically, the end of the support part 3 away from the fixed part 1 is inclined to the outer side of the support part 3. This arrangement can make the end of the support part 3 away from the fixed part 1 extrude and deform inward when the support part 3 is connected with the door frame upright 100, thereby improving the sealing performance of the bending part 4 in the gap between the door frame upright 100 and the door leaf 102.

[0035] In some other embodiments, the KS6319 sealing strip comprises an elastic foaming material and a film covering the elastic foaming material. The elastic foaming material is super-high-rebound polyurethane (PU), and the film is polypropylene (PE) film.

[0036] Further, the elastic foaming material is flame-retardant foaming material, and the film is flame-retardant PE film.

[0037] The flame-retardant foaming agent is one of polyurethane foaming agents, which adds the effect of flame retardation on the basis of the original foaming agent function.

[0038] The flame-retardant foaming agent not only can prevent the spread of fire, but also can delay the spread of fire when encountering fire, so as to gain time for rescue personnel. Such foaming agent is favored by many industrial merchants and is widely used in housing construction and industrial products. The detection method of the flame-retardant foaming agent usually includes the foaming height method, and the detection items include quality detection, volatile matter detection, decomposition temperature detection, gas generation amount detection, performance detection, foam performance detection, and component detection. In addition, the detection standard of the flame-retardant foaming agent includes the test of ASTM D7132-2014 for determining residual foaming agent in extruded foam plastic.

[0039] The flame-retardant PE film is a special treated polyethylene film, which has excellent flame retardant performance. It can slow down the spread of fire when encountering fire source by adding flame retardant in the PE film, thereby improving the safety of the material.

[0040] In an implementation manner, the adhesive 5 adopts double-sided adhesive tape. The KS6319 sealing strip is connected with the door frame upright 100 and the door frame door strip 101 through the double-sided adhesive tape, and this connection mode is simple, convenient, and fast.

[0041] Specifically, a plurality of chamfers are arranged in the accommodating cavity 11 to avoid stress concentration at the corners in the accommodating cavity 11.

[0042] Specifically, a chamfer is arranged at the corner of the outer periphery of the KS6319 sealing strip to avoid stress concentration at the corner of the outer periphery of the sealing strip, so that the corner is not broken.

[0043] The above is only a preferred embodiment of the utility model, and does not limit the utility model. Any modification, equivalent replacement, and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
