DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] In the description of this application, if the orientation description is involved, for example, the orientation or position relationship indicated by "upper", "lower", "front", "back", "left", "right", etc. is based on the attached Figure 3 The orientation or position relationship shown is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation of the present application. When a feature is referred to as being "set", "fixed", or "connected" to another feature, it can be directly set, fixed, or connected to the other feature, or it can be indirectly set, fixed, or connected to the other feature.

[0021] See also Figure 1-3 The present application provides the following technical solutions: a steel cabinet sliding door durability testing machine, comprising a base 13; cabinet clamping mechanisms are provided at both left and right ends of the upper surface of the base 13, a manual linear guide 10 is installed on the front side of the base 13, the manual linear guide 10 is connected to an electric telescopic rod 8 through a slide 9, and a door handle clamp 2 corresponding to the sliding door handle of the cabinet 1 to be tested is installed at the telescopic end of the electric telescopic rod 8.

[0022] Specifically, the cabinet 1 to be tested is hung on the upper surface of the base 13, and then the cabinet 1 to be tested is fixed by the cabinet clamping mechanism arranged on the left and right sides of the upper surface of the base 13, and then the lifting and lowering of the door handle clamp 2 is adjusted by the manual linear guide 10, so that the door handle clamp 2 can be clamped together with the handle of the sliding door of the cabinet 1 to be tested, and the electric control telescopic rod 8 is started to test the sliding door.

[0023] The cabinet clamping mechanism comprises a bracket 5, a guide rail 4 is installed on the outer side of the bracket 5, a translation slider 7 is slidably connected to the guide rail 4, a screw rod 6 is threadedly connected to the translation slider 7, and a clamping plate 3 is rotatably connected to the end of the screw rod 6.

[0024] Specifically, the screw rod 6 is rotated, and the screw rod 6 pushes the clamping plates 3 to move toward the cabinet body 1 to be tested, until the clamping plates 3 on both sides are clamped on the outer surface of the cabinet body 1 to be tested.

[0025] More specifically, when the door of the cabinet body 1 to be tested is closed, its handle can be fixed on the clamping plate 3, thereby ensuring that the sliding door can reach the maximum stroke when opening and closing.

[0026] Furthermore, a locking universal wheel 12 is provided on the lower surface of the base 13 .

[0027] Specifically, there are four locking universal wheels 12 , and the four locking universal wheels 12 are evenly distributed on the lower surface of the base 13 .

[0028] Furthermore, the translation slider 7 is fixed on the guide rail 4 by bolts.

[0029] Specifically, loosening the bolt can change the position of the translation slider 7 .

[0030] Furthermore, a crank 11 is installed on the screw rod of the manual linear guide rail 10 .

[0031] Specifically, the arrangement of the crank 11 facilitates the lifting and lowering adjustment of the door handle clamp 2 .

[0032] Furthermore, the door handle clamp 2 is a U-shaped slot.

[0033] Specifically, the U-shaped slot can be quickly connected with the handle of the sliding door.

[0034] More specifically, the door handle fixture 2 can be made of a strong magnet. When the sliding door to be tested has no protruding handle, the strong magnet is used to adsorb on the cabinet door for testing.

[0035] Furthermore, a positioning block 14 is provided on the upper surface of the base 13 near the cabinet 1 to be tested, and the positioning block 14 is fixed to the upper surface of the base 13 by bolts.

[0036] Specifically, the position of the positioning block 14 can be adjusted as needed.

[0037] When in use: the cabinet 1 to be tested is hung on the upper surface of the base 13, and the screw 6 is rotated, and the screw 6 pushes the clamp 3 to move toward the cabinet 1 to be tested until the clamps 3 on both sides are clamped on the outer surface of the cabinet 1 to be tested, and then the manual linear guide 10 is used to adjust the lifting and lowering of the door handle clamp 2 so that the door handle clamp 2 can be clamped together with the handle of the sliding door of the cabinet 1 to be tested, and the electric control telescopic rod 8 is started to test the sliding door.

[0038] During the test, the electric telescopic rod 8 is controlled to extend and retract through the external touch screen PLC, simulating people repeatedly opening and closing the door. According to the standard or actual use, the appropriate parameters such as the door push speed are set. When the door is opened and closed cyclically, observe whether the door operates smoothly, and whether there are abnormal sounds, jams, etc. In a specific cycle (such as every 10,000 times, 50,000 times, and 100,000 times), check various performance indicators of the door, including whether the door frame and door leaf are deformed, whether the slide rails and rollers are worn, and whether the locking mechanism is reliable. Continue the test to the predetermined number of opening and closing times (such as 200,000 times, 500,000 times), or until the sliding door is unacceptably damaged or performance degrades.

[0039] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
