DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 8 , the present invention provides a technical solution: Embodiment 1: A detection device for door and window rubber strips, including a detection frame 1. Installation grooves are provided on both sides of the detection frame 1. A detection plate 3 is arranged in the installation grooves. A rubber strip 10 to be detected is installed on the detection plate 3. A pair of clamping end blocks 13 located at both ends of the rubber strip 10 are arranged on the detection plate 3. A fixed block 8 is arranged in the middle of the detection frame 1. Traction crossbeams 4 are telescopically sleeved on both sides of the fixed block 8 along the parallel direction of the rubber strip 10. The traction crossbeams 4 are connected to the end blocks 13. Pressing members 11 are arranged on both sides of the fixed block 8 along the perpendicular direction of the rubber strip 10. The pressing members 11 are respectively connected to a pair of symmetrically distributed traction crossbeams 4 through a pair of rotating rods 7. An expansion rod 2 for driving the traction crossbeam 4 to slide is arranged on the detection frame 1.

[0021] By setting the expansion rod 2 to drive a pair of traction crossbeams 4 to slide relatively, through the transmission of the rotating rod 7 and lateral extrusion, the pressing member 11 is driven to press on the rubber strip 10, so as to realize the extrusion test on the rubber strip 10. When the expansion rod 2 drives the traction crossbeams 4 to move away relatively, the pressing member 11 is separated from the rubber strip 10, and at the same time, the end block 13 pulls the rubber strip 10 to be longitudinally stretched. In this way, with the reciprocating expansion and contraction of the expansion rod 2, multiple longitudinal stretches and vertical extrusions of the rubber strip 10 are realized, which is convenient for detecting the elastic fatigue degree of the rubber strip 10.

[0022] Embodiment 2: On the basis of Embodiment 1, an installation strip 12 is arranged on the detection plate 3. The rubber strip 10 is sleeved on the installation strip 12, and the length of the rubber strip 10 is greater than the length of the installation strip 12.

[0023] The fixed installation of the rubber strip 10 is realized by setting the installation strip 12. Guide rods 16 parallel to the rubber strip 10 are arranged on both sides of the end of the installation strip 12. The end block 13 is slidably sleeved on the guide rods 16. A lower fixing plate 21 that fits the inner wall of the rubber strip 10 and a clamping plate 22 that elastically presses on the outer wall of the rubber strip 10 are arranged on the end block 13. A connecting member for conveniently connecting the traction crossbeam 4 is arranged on the end block 13; a telescopic groove 23 is arranged on the end block 13. A connecting rod is arranged in the telescopic groove 23. One end of the clamping plate 22 is sleeved on the connecting rod, and a second spring 25 is sleeved on the connecting rod. One end of the second spring 25 presses on the clamping plate 22.

[0024] The clamping of the end of the rubber strip 10 by the end block 13 is realized by setting the elastically installed clamping plate 22 and the lower fixing plate 21.

[0025] The connecting piece includes a right-angled cavity block 20. Inside one end port of the right-angled cavity block 20, a pressing block 24 facing the clamping plate 22 is slidably installed. The other end port of the right-angled cavity block 20 faces one end of the traction cross beam 4, and a cross-slot end plate 27 is fixedly installed at the port position. A through hole is provided in the middle of the cross-slot end plate 27, and a cross-shaped through groove is provided on the inner wall of the through hole. A rotating shaft 5 inserted along the through hole is rotatably installed on the traction cross beam 4, and a cross ring 28 matching the cross-shaped through groove is provided on the rotating shaft 5; piston blocks 26 are provided at the ends of the rotating shaft 5 and the pressing block 24, and the rotating shaft 5 is rotatably installed on the piston block 26 by bearings. The piston block 26 slides along the inner wall of the right-angled cavity block 20, and the cross ring 28 extends to the lower end of the cross-slot end plate 27 and is rotationally misaligned with the through groove under the insertion of the rotating shaft 5.

[0026] By inserting the rotating shaft 5, the purpose of squeezing the pressure inside the right-angled cavity block 20 is achieved, driving the pressing block 24 to slide outward and press on the clamping plate 22, driving the clamping plate 22 to further clamp the end of the rubber strip 10, realizing stable clamping. By using the rotation of the rotating shaft 5, the misalignment between the cross ring 28 and the cross-slot end plate 27 is realized, and then the rotating shaft 5 is connected to the right-angled cavity block 20, and under the action of the traction cross beam 4, the end block 13 is driven to move together.

[0027] Embodiment 3: On the basis of Embodiment 2, an inner long groove pressing against the outer wall of the rubber strip 10 is provided on one side of the extrusion piece 11. An air outlet long groove 18 is provided at the lower end of the inner long groove, a visible long groove 30 is provided at the upper end of the inner long groove, a fluff strip 19 is provided in the visible long groove 30, a hose 14 communicating with the fixed block 8 is provided on the other side of the extrusion piece 11, an air pump interface 15 for connecting an external air pump is provided at the upper end of the fixed block 8, the air pump interface 15 is connected to the hose 14 through the inner cavity of the fixed block 8, and the other end of the hose 14 communicates with the air outlet long groove 18 through the internal flow channel of the extrusion piece 11.

[0028] When the extrusion piece 11 is pressed on the rubber strip 10, air is introduced into the air pump interface 15 through the air pump, so that the air flow is vertically ejected along the air outlet long groove 18 at the lower end of the gap where the extrusion piece 11 is pressed against the rubber strip 10. When the fluff strip 19 floats upward, it proves that the sealing performance of the rubber strip 10 is not good.

[0029] A sliding groove in the vertical direction of the rubber strip 10 is provided in the detection frame 1. A slider 29 is provided at the lower end of the extrusion piece 11, and the slider 29 is slidably inserted into the sliding groove; a sleeve 6 is provided at the lower end of the traction cross beam 4, a sleeve rod 9 slidably sleeved with the sleeve 6 is provided on the fixed block 8, rotating seats are provided at the lower end port of the sleeve 6 and on the extrusion piece 11, and both ends of a rotating rod 7 are rotatably installed on the rotating seats. A first spring 17 is sleeved on the sleeve rod 9, and the first spring 17 is pressed between the sleeve 6 and the fixed block 8.

[0030] By setting the cooperation between the slider 29 and the chute, the limited lateral sliding of the extrusion part 11 is realized, avoiding deviation and ensuring the position accuracy of mutual extrusion. By setting the cooperation between the first spring 17 and the sleeve 6 and the sleeve rod 9, the smooth sliding of the traction cross beam 4 is ensured.

[0031] During the detection process: First, set the glue condition 10 on the detection plate 3 and install it in the detection frame 1. Through the drive of the telescopic rod 2, the rotating shaft 5 is inserted and rotated out of position, realizing the connection between the traction cross beam 4 and the end block 13; Utilize the reciprocating motion of the telescopic rod 2 to traction the end block 13 to reciprocally stretch the glue condition 10 and detect its stretching elasticity; Utilize the telescopic drive of the telescopic rod 2 to make the extrusion part 11 reciprocally press on the glue condition 10 and detect its deformation and reset performance after being pressed; After multiple reciprocating stretches and compressions, 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 fluff strip 19 flutters. If there is no fluttering, the performance of the glue condition 10 is intact and the sealing performance is good. If there is fluttering, it indicates that the glue condition 10 is deformed and fatigued, generating gaps.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
