Detailed ways

Preferred embodiment of the present utility model is described as follows in conjunction with accompanying drawing:

Embodiment one:

As shown in Figure 1, the luggage vibration fatigue testing machine of the utility model includes an aluminum alloy equipment frame (1), a cylinder (4) and a luggage test fixture (10) equipped with a safety net, and is characterized in that the equipment frame (1 ) on the upper and lower beam frames (2, 2') respectively install the upper and lower load-bearing plates (3, 3'), a cylinder (4) is vertically fixed on the upper load-bearing plate (3), and the cylinder (4) The piston rod passes through the center of the upper bearing plate (3) and is fixedly connected with an electromagnet mounting plate (6), and an adsorption mounting plate (7) is provided below the electromagnet mounting plate (6). Two parallel column guide rails (5) are horizontally fixed between the upper and lower load-bearing plates (3, 3'), slidingly matched with the electromagnet mounting plate (6) and the adsorption mounting plate (7); the adsorption mounting plate (7 ) is connected to a luggage test fixture (10) through a rod (9), the luggage test fixture (10) is threadedly connected with the rod (9) and fixed by two nuts, and the rod (9) The other end is fixed on the adsorption mounting plate (7) through threaded connection, and fixed by a nut; a vibration spring (8) is set on the rod (9), and one end of the spring (8) is supported on the adsorption mounting plate (7). The other end rests on the lower bearing plate (3').

Embodiment two:

This embodiment is basically the same as Embodiment 1, especially in that:

As shown in Figure 2, the structure of the fixture (10) for luggage testing is: a fixture base (11) and a fixture cover (12), one end of the fixture base (11) and one end of the fixture cover (12) The other end of the clamp base (11) is connected with the other end of the clamp cover (12) by two bolts (16) through the pin shaft (17); there is a screw hole in the center of the clamp cover (12), and the screw hole An adjusting screw (15) is screwed; the inner end of the adjusting screw (15) is fixedly connected with an adjusting plate (13), and the outer end is screwed with a lock nut (14).

It works as follows:

As shown in Figure 1, firstly, the handle of the luggage is reliably fixed by a jig (10) for luggage testing, and the electromagnet is energized to make the electromagnet mounting plate (6) absorb the adsorption mounting plate (7). The electromagnet mounting plate (6) rises to a predetermined height together with the adsorption mounting plate (7), and then the electromagnet is powered off, and the adsorption mounting plate (7) falls freely together with the luggage under the guidance of the column guide rail (5). Under the action of the spring force of the spring (8), the adsorption mounting plate (7) together with the case and bag reciprocates up and down to generate oscillation. By setting different predetermined heights, the vibration strength of the vibration spring (8) is different when the testing machine is working, so as to meet different requirements for vibration fatigue strength testing.
