[0020] Please refer to Figure 1 to Figure 2 , a quick clamping test device for a window lifter provided by the present invention comprises a fixing mechanism 10 and two tension testers 20, the fixing mechanism 10 comprises a fixing platform 11, at least two transverse receiving members 12 slidably mounted in the length direction of the fixing platform 11, at least two longitudinal receiving members 13 slidably mounted in the width direction of the fixing platform 11 and at least two clamping assemblies 14 slidably mounted in the width direction of the fixing platform 11, in this embodiment, the clamping assembly 14 is located above the transverse receiving member 12, and the longitudinal receiving member 13 is located below the transverse receiving member 12, the transverse receiving member is used to receive the guide rail of the window lifter A, this embodiment shows a window lifter with two guide rails, a motor and steel wires, the structure of the window lifter A is the prior art and is not the focus of the present invention, so its structure is not described in detail, the window lifter A shown in the figure of the present invention is to allow those skilled in the art to better understand the principle of clamping.

[0021] The two tension testers 20 are respectively fixed at both ends of the length direction of the fixed platform 11. The tension tester 20 includes a test frame 21 and a tension test block 22 that can be lifted and suspended on the test frame 21 through a wire pulley assembly 30. The wire pulley assembly 30 includes a steel wire 31 and a plurality of pulleys 32 respectively installed on the top of the tension test block 22 and on the test frame 21. The steel wire 24 is wound around the test frame 21 and the pulley 32 of the tension test block 22, so that the tension test block 22 can be lifted and suspended on the tensioner 20. When the fixing mechanism fixes the window lifter A to be tested, the end of the steel wire 24 is connected to the sliding part (the part used to push up the glass) of the window lifter A, so that the sliding part of the window lifter can drive the tension test block to lift and lower, and then the motor of the window lifter A is powered on, so that the motor and the sliding part of the window lifter A can be tested.

[0022] In this embodiment, since the window lifter A exhibits double guide rails and pulleys 23 are provided at the four corners of the top of the tension test block 22, the sliding parts of the double guide rails can be fixed to the ends of the steel wires, and the fixing method can adopt a practical and commonly used fixing clamp or be fixed by winding. The technicians in this field can select the corresponding accessories according to the actual situation. It is only necessary to connect the steel wire to the sliding part. The sliding part can pull the tension test block 22 to rise and fall on the test frame 21 during the sliding process.

[0023] In this embodiment, a level measuring instrument (not shown in the figure) for detecting the inclination of the tensile test block 22 can be provided on the top of the tensile test block 22. The level measuring instrument can be purchased from the market, whether it is in electronic form, sensor form, or water drop form, as long as it can detect whether the tensile test block 22 is parallel to the horizontal line. Whether the tensile test block 22 is parallel to the horizontal line can determine whether the sliding of the sliding parts on the double guide rails is consistent, so that it can be detected whether the glass can be stably raised and lowered in actual use.

[0024] In this embodiment, two slide grooves 111 are provided in the length direction of the fixed platform 11, and the slide grooves 111 are close to the two ends of the fixed platform 11 in the width direction. The longitudinal receiving member 13 includes two first longitudinal sliders 131 and a longitudinal support bar 132 connected between the two sliders 131. The two first longitudinal sliders 131 can be slidably installed in the two slide grooves 111 respectively. In this embodiment, in order to position each longitudinal receiving member 13, a through slot 112 is provided opposite to the two slide grooves 111 of the end face of the fixed platform 11. Each of the first longitudinal sliders 131 is screwed with a tightening bolt 133, and the tightening bolt 133 extends out of the fixed platform 11 through the through slot 112, so that the user twists the tightening bolt 133 to make its end contact with the inner wall of the slide groove 111, thereby achieving the effect of positioning the first longitudinal slider 131.

[0025] In this embodiment, guide rail pairs 121 are respectively provided at both ends of the fixed platform 11 in the width direction, and the guide rail pairs 121 are provided with the same number of guide rail sliders as the transverse supporting member 12. The two ends of the transverse supporting member 12 are connected to the guide rail sliders at both ends of the fixed platform 11 in the width direction, so that the transverse supporting member 12 can be moved with the help of the guide rail sliders.

[0026] In this embodiment, the clamping assembly 14 includes two second longitudinal sliders 141, a fixing rod 142 connected to the two second longitudinal sliders 141, a swinging plate 143 swingably mounted on the fixing rod 142 through a rotating shaft B, a mounting plate 144 facing the direction of the fixed platform 11 and rotatably suspended on the swinging plate 143, a clamp 145 mounted side by side on the mounting plate 144, and an elastic assembly 15 mounted on the fixing rod 142 for providing downward pressure to the swinging plate 143. The swinging plate 143 is pressed toward the fixed platform 11 by the elastic assembly 15, so that the clamp 145 is pressed toward the fixed platform 11 by the mounting plate 144. When the window lifter A is placed on the transverse receiving member 12 and the longitudinal receiving member 13, it is pressed downward by the clamp 145. The rotatable feature of the mounting plate 144 makes it convenient for the user to adjust the position of the clamp 145 at any time, so as to facilitate the clamping of window lifters of different sizes and models.

[0027] In this embodiment, the elastic component 15 includes a mounting slot plate 151 having a concave cross-section and fixed on the fixing rod 142, a rack 152 installed in the mounting slot plate 151, and a spring 153 installed in the mounting slot plate 151 and respectively fixed to the rack 152 and the end of the mounting slot plate 151, and a gear 154 fixed on the rotating shaft B and meshing with the rack 152. The spring 153 provides elastic force for the rack, and then the gear meshing with it has a rotational force, so that the swing plate always has a pressing force against the fixed platform.

[0028] In this embodiment, the clamp 145 includes a fixing column 145A fixed on the mounting plate and a rubber plug 145B fixed to the end of the fixing column 145A. The rubber plug 145B can prevent the relevant position of the clamp from being crushed or scratched.
