[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 8 The present invention provides a technical solution: Example 1: A door and window sealing strip testing device includes a testing frame 1, with mounting grooves on both sides of the testing frame 1, a testing plate 3 in the mounting grooves, a sealing condition 10 to be tested mounted on the testing plate 3, a pair of clamping end blocks 13 located at both ends of the sealing condition 10 on the testing plate 3, a fixing block 8 in the middle of the testing frame 1, a traction beam 4 telescopically connected to both sides of the fixing block 8 along the parallel direction of the sealing condition 10, the traction beam 4 connected to the end blocks 13, and extrusion members 11 on both sides of the fixing block 8 along the perpendicular direction of the sealing condition 10, the extrusion members 11 being connected to a pair of symmetrically distributed traction beams 4 via a pair of rotating rods 7, and a telescopic rod 2 for driving the traction beams 4 to slide on the testing frame 1.

[0021] By setting a telescopic rod 2 to drive a pair of traction beams 4 to slide relative to each other, and through the transmission and lateral extrusion of the rotating rod 7, the extrusion piece 11 is driven to press against the adhesive condition 10, thus realizing the extrusion test of the adhesive condition 10. When the telescopic rod 2 drives the traction beams 4 to move away from each other, the extrusion piece 11 separates from the adhesive condition 10, and at the same time the end block 13 pulls the adhesive condition 10 longitudinally. Thus, with the reciprocating extension and retraction of the telescopic rod 2, the adhesive condition 10 is subjected to multiple longitudinal stretching and vertical extrusion, which facilitates the detection of the elastic fatigue of the adhesive condition 10.

[0022] Example 2: Based on Example 1, the detection plate 3 is provided with an installation strip 12, and the adhesive condition 10 is sleeved on the installation strip 12. The length of the adhesive condition 10 is greater than the length of the installation strip 12.

[0023] The adhesive condition 10 is fixedly installed by setting the installation strip 12. The ends of the mounting strip 12 are provided with guide rods 16 parallel to the adhesive condition 10. The end block 13 is slidably sleeved on the guide rods 16. The end block 13 is provided with a lower fixing plate 21 that fits against the inner wall of the adhesive condition 10 and a clamping plate 22 that is elastically pressed against the outer wall of the adhesive condition 10. The end block 13 is provided with a connector that can be easily connected to the traction beam 4. The end block 13 is provided with a telescopic groove 23. A connecting rod is provided in the telescopic groove 23. One end of the clamping plate 22 is sleeved on the connecting rod. A second spring 25 is sleeved on the connecting rod. One end of the second spring 25 is pressed against the clamping plate 22.

[0024] The end block 13 is clamped to the end of the adhesive condition 10 by setting the elastically installed clamping plate 22 and the lower fixing plate 21.

[0025] The connector includes a right-angled cavity block 20. A pressure block 24 facing the clamping plate 22 is slidably installed in one end port of the right-angled cavity block 20. The other end port of the right-angled cavity block 20 faces one end of the traction beam 4, and a cross-groove end plate 27 is fixedly installed at the port position. A through hole is provided in the middle of the cross-groove end plate 27. A cross-shaped through groove is provided on the inner wall of the through hole. A rotating shaft 5 is rotatably installed on the traction beam 4 and inserted along the through hole. A cross ring 28 that cooperates with the cross-shaped through groove is provided on the rotating shaft 5. A piston block 26 is provided at the end of the rotating shaft 5 and the end of the pressure block 24. The rotating shaft 5 is rotatably installed on the piston block 26 with a bearing. The piston block 26 slides along the inner wall of the right-angled cavity block 20. The cross ring 28 extends to the lower end of the cross-groove end plate 27 under the insertion of the rotating shaft 5 and rotates and is offset from the through groove.

[0026] The insertion of the rotating shaft 5 achieves the purpose of compressing the internal pressure of the right-angle cavity block 20, driving the pressure block 24 to slide outward and press against the clamping plate 22, driving the clamping plate 22 to further clamp the end of the adhesive condition 10, achieving stable clamping. By utilizing the rotation of the rotating shaft 5, the cross ring 28 and the cross groove end plate 27 are misaligned, and then the rotating shaft 5 is connected to the right-angle cavity block 20, driving the end block 13 to move together under the action of the traction beam 4.

[0027] Example 3: Based on Example 2, one side of the extruder 11 is provided with an inner long groove that presses against the outer wall of the adhesive condition 10. The lower end of the inner long groove is provided with an air outlet long groove 18, and the upper end of the inner long groove is provided with a visible long groove 30. A fluff strip 19 is provided in the visible long groove 30. The other side of the extruder 11 is provided with a hose 14 that communicates with the fixing block 8. The upper end of the fixing block 8 is provided with an air pump interface 15 for connecting an external air pump. The air pump interface 15 is connected to the hose 14 through the inner cavity of the fixing block 8. The other end of the hose 14 is connected to the air outlet long groove 18 through the internal flow channel of the extruder 11.

[0028] When the extruder 11 is pressed onto the adhesive condition 10, air is introduced into the air pump interface 15 through the air pump, so that the airflow is vertically sprayed along the air outlet groove 18 onto the lower end of the gap between the extruder 11 and the adhesive condition 10. When the pile strip 19 floats upward, it proves that the adhesive condition 10 has poor sealing performance.

[0029] The detection frame 1 is provided with a groove perpendicular to the adhesive condition 10. The lower end of the extruder 11 is provided with a slider 29, which is slidably inserted into the groove. The lower end of the traction beam 4 is provided with a sleeve 6. The fixed block 8 is provided with a sleeve rod 9 that is slidably fitted with the sleeve 6. The lower end of the sleeve 6 and the extruder 11 are provided with a rotating seat. The two ends of the rotating rod 7 are respectively rotatably installed on the rotating seat. The sleeve rod 9 is fitted with a first spring 17, which is pressed between the sleeve 6 and the fixed block 8.

[0030] By setting the slider 29 and the groove to cooperate, the extrusion part 11 is limited to lateral sliding, avoiding deviation and ensuring the positional accuracy of mutual extrusion. By setting the first spring 17 and the sleeve 6 and the sleeve rod 9 to cooperate, the smooth sliding of the traction beam 4 is ensured.

[0031] During the testing process: First, set the adhesive condition 10 on the detection plate 3 and install it in the detection frame 1. Driven by the telescopic rod 2, the rotating shaft 5 is inserted and rotated in a staggered manner to realize the connection between the traction beam 4 and the end block 13. Using the reciprocating motion of the telescopic rod 2, the end block 13 is pulled to reciprocate and stretch the rubber condition 10, and its elasticity is tested. The telescopic rod 2 is used to drive the extrusion piece 11 to reciprocate and press it against the adhesive condition 10, and its deformation recovery performance after being pressed is tested. After repeated stretching and squeezing, observe whether there is deformation. If there is no obvious deformation, then under the extrusion state, introduce air into the interior and observe whether the pile strip 19 moves. If it does not move, the performance of adhesive condition 10 is intact and the sealing performance is good. If it moves, it indicates that adhesive condition 10 is deformed and fatigued, resulting in gaps.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
