[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4, A tensile test device for a hardware rigging, including a force - applying component for pulling and testing the hardware rigging, and also including a table component for supporting and limiting. An adjusting component for actively adjusting the tensile length is installed on the table component, and the force - applying component is installed on the adjusting component.

[0024] In this embodiment: The table component includes a workbench 101. The workbench 101 is 3 meters long. A number of limiting holes 102 are evenly distributed on the workbench 101. The limiting holes 102 are symmetrically distributed in two rows, and the spacing between the limiting holes 102 in each row is 50 centimeters. Four supporting legs 103 are evenly distributed at the four corners of the bottom of the workbench 101. The supporting legs 103 are welded to the workbench 101, and the supporting legs 103 support and fix the workbench 101. The limiting holes 102 are used to adjust the distance between the two columns 202 to suit the tensile test of hardware riggings of different lengths.

[0025] The adjusting component includes two symmetrically arranged bases 201. Columns 202 are arranged on the bases 201. Both the columns 202 and the bases 201 are made of 45 steel material and are welded together. Two limiting pins 203 are symmetrically installed at both ends of the base 201. According to the length of the hardware rigging, the two bases 201 are respectively aligned with the limiting holes 102 on the workbench 101, and then the limiting pins 203 are inserted through the bases 201 and into the limiting holes 102 for fixation. One column 202 fixes a limiting hook 301 through a stud 302, and the other column 202 supports the other limiting hook 301 through a fixed telescopic cylinder 304.

[0026] In this embodiment: The force - applying component includes two limiting hooks 301. Studs 302 and connecting seats 303 are respectively arranged at the ends of the two limiting hooks 301. The studs 302 and the limiting hooks 301 are integrally formed. A telescopic cylinder 304 is installed on one side of the connecting seat 303. The telescopic cylinder 304 is bolt - connected to the column 202 and the connecting seat 303 respectively. One limiting hook 301 is connected to one column 202 through a stud 302 to fix one end of the hardware rigging, and the other limiting hook 301 is driven by the telescopic cylinder 304 to drive the other end of the hardware rigging to move, thereby stretching the hardware rigging for testing.

[0027] Working principle: First, according to the length of the hardware rigging, the two bases 201 are respectively aligned with the limiting holes 102 on the workbench 101, and then the limiting pins 203 are inserted through the bases 201 and into the limiting holes 102 for fixation. Then, the two ends of the hardware rigging are respectively sleeved on the two limiting hooks 301. During the test, the column 202 supports the telescopic cylinder 304 to retract, drives the limiting hook 301 to pull one end of the hardware rigging through the connecting seat 303, and enables the column 202 at the other end to support the limiting hook 301 through the stud 302 to fix the other end of the hardware rigging for tensile testing.
