[0025] A metal chain tension testing device includes an outer shell 1, the bottom wall of which is provided with a support column and a servo motor 10. The front of the outer shell 1 is open, and two cover doors 11 are provided at the opening through a plurality of hinges. When the cover doors 11 are opened, two metal chains can be quickly installed and placed inside the outer shell 1, which is convenient for subsequent tension testing. The two cover doors 11 are made of tempered glass, which not only plays a protective role but also allows for convenient observation of the internal testing status. The cover doors 11 are provided with a control panel 12, which is electrically connected to two pressure sensors 8 and the servo motor 10, and can display and record the pressure value changes sensed by the pressure sensor 8, and record the test results.

[0026] The two cover doors 11 are movably connected via a plurality of connecting units, which include a rotating rod 13 rotatably arranged on the outer wall of one of the cover doors 11 , and an L-shaped block 14 fixedly arranged on the outer wall of the other cover door 11 , and the rotating rod 13 is movably connected to the L-shaped block 14 .

[0027] After aligning the two cover doors 11, twist the rotating rod 13 so that the other end thereof rotates into the inside of the L-shaped block 14. The outer wall of the L-shaped block 14 can fix the rotating rod 13 to the outer wall of the cover door 11, making it convenient to open the cover door 11 to place the metal chain 5 and also convenient to quickly close the cover door 11.

[0028] A bidirectional screw rod 2 is rotatably provided on the side wall of the outer shell 1. One end of the bidirectional screw rod 2 passes through the side wall of the outer shell 1 and is fixedly provided with a knob 17. A group of movable seats 3 are threadedly connected to the outer wall of the bidirectional screw rod 2. A fixed pull ring 4 is provided on the one group of movable seats 3 and the top wall of the outer shell 1. The fixed pull ring 4 can be movably connected to the end of the metal chain 5. A reciprocating screw rod 6 perpendicular to it is provided below the bidirectional screw rod 2.

[0029] The distance between the movable seats 3 can be adjusted according to the length of the metal chain 5 to achieve an appropriate tension of the metal chain 5. By turning the knob 17, it drives the bidirectional screw rod 2 to rotate, thereby driving the movable seats 3 to move closer to or away from each other, so that the metal chain 5 hanging between the fixed pull rings 4 is in an appropriately tensioned state.

[0030] Three limit grooves 15 are fixedly provided on the inner side wall of the back side of the outer shell 1, two of which are symmetrically arranged and parallel to the bidirectional screw 2, and the other limit groove 15 is parallel to the reciprocating screw 6. A horizontal plate 16 is provided between the side walls of the outer shell 1, and the top end of the reciprocating screw 6 is rotatably set on the bottom wall of the horizontal plate 16, and the other end passes through the bottom wall of the outer shell 1 and is set at the output end of the servo motor 10. Starting the servo motor 10 can drive the reciprocating screw 6 to rotate, and then drive the movable block 7 to move up and down.

[0031] The outer wall of the reciprocating screw 6 is threadedly connected to a movable block 7, and pressure sensors 8 are fixedly provided at both ends of the top wall of the movable block 7. When the movable block 7 moves downward, it can simultaneously drive the end of one metal chain and the middle section of another metal chain to move downward, so that the two pressure sensors 8 can read the tensile force in the two states respectively.

[0032] Another fixed pull ring 4 and a fixed circular ring 9 are fixed on the top of the pressure sensor 8. The other fixed pull ring 4 and the fixed circular ring 9 are movably connected to the other end and the middle section of the metal chain 5. The upper and lower ends of the vertical metal chain 5 are respectively fixed inside the fixed pull ring 4. One end of the horizontal metal chain 5 is first fixed inside the fixed pull ring 4, and the other end passes through the interior of the fixed circular ring 9 and then fixed inside the fixed pull ring 4 on the other side.

[0033] A set of movable seats 3 and movable blocks 7 are slidably arranged in three limiting grooves 15, respectively. The three limiting grooves 15 can guide and stabilize the movement of the set of movable seats 3 and movable blocks 7. The inner ends of the fixed pull ring 4 and the fixed circular ring 9 are both rotatably arranged on the inner wall of the support seat 19. The fixed pull ring 4 is provided with an opening near the inner end. The end of the metal chain 5 can enter the inner ring of the fixed pull ring 4 through the opening, which facilitates and quickly installs the metal chain 5. The fixed circular ring 9 is close to one end of the bidirectional screw rod 2, and its inner ring can accommodate the metal chain 5 to pass through. The fixed circular ring 9 can drive the middle section of the metal chain 5 to move downward to realize the tension detection of the middle section.

[0034] A material receiving trough 18 is also movably placed at the bottom of the outer shell 1. The material receiving trough 18 is an upward-opening structure and includes a hard block 21 and two sections of soft rubber blocks 20. The hard block 21 is close to the cover door 11, and the two sections of soft rubber blocks 20 are close to the back of the outer shell 1. The inner walls of the hard block 21 and the two sections of soft rubber blocks 20 are surrounded by each other to form a through groove 22, and the reciprocating screw rod 6 can rotate freely inside the through groove 22.

[0035] During the inspection, the broken metal chain 5 residue falls into the receiving trough 18 below, which makes it convenient to open the cover door 11 regularly to clean the residue. The two sections of soft rubber blocks 20 are elastic, which makes it convenient to pry open the gap between the two sections of soft rubber blocks 20 so that the reciprocating screw rod 6 can enter and exit the through groove 22, making it convenient for the receiving trough 18 to take out the outer shell 1 or place it at the bottom of the outer shell 1.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
