The fixed plate 1 is vertically arranged, and the fixed plate 1 includes a front side and a back side. The front part of the fixed plate 1 is a space that can control the ambient temperature. The fixed plate 1 serves as a test space separator. The driving device 2, the tensioning device 3, and the test component 4 are installed on the fixed plate 1. The driving device 2 includes a pulley 21 and a motor 22. The pulley 21 is located on the front side of the fixed plate 1, and the motor 22 is located on the back side of the fixed plate 1. The motor 22 drives the pulley 21 to rotate. The motor 22 is separated by the fixed plate 1 on the back side, which can better protect the motor 22 from the influence of environmental changes and ensure the life of the motor 22.

[0020] The test assembly 4 is installed on the front side of the fixed plate 1. The test assembly 4 includes a mounting plate 41 and a plurality of mounting seats 42. Each mounting seat 42 can be equipped with a tensioning wheel 43. The mounting plate 41 is fixedly installed on the front side of the fixed plate 1. The mounting plate 41 is provided with a plurality of first mounting holes 411. The first mounting holes 411 are arranged in a horizontal and vertical array. The mounting seat 42 includes a ring seat 421 and a connecting column 422. The ring seat 421 is provided with a plurality of second mounting holes 4211. There are four second mounting holes 4211. The four second mounting holes 4211 are evenly sealed in a ring shape on the ring seat 421. Closed, the ring seat 421 is connected to the fixed plate 1, the second mounting hole 4211 corresponds to the first mounting hole 411, and is fixed by bolts passing through the first mounting hole 411 and the second mounting hole 4211. Multiple mounting seats 42 can be arranged according to the number of tensioning pulleys 43 that need to be tested, and the belt 6 can be made to make the wrap angle of each tensioning pulley 43 reach 120° as much as possible. The tensioning pulley 43 is installed on the end of the connecting column 422 away from the fixed plate 1. All the tensioning pulleys 43 and the pulley 21 are in the same plane position, so that the belt 6 can better drive all the tensioning pulleys 43.

[0021] The tensioning device 3 is installed on the front side of the fixed plate 1. The tensioning device 3 includes a base plate 31, a movable plate 32, and a support wheel 33. The base plate 31 is fixedly installed on the fixed plate 1. The base plate 31 is provided with a slide rail. The movable plate 32 is slidably connected to the base plate 31 through the slide rail. The support wheel 33 is fixedly installed on the movable plate 32. The pulling assembly 5 can drive the support wheel 33 to move closer to or away from the pulley 21.

[0022] The pulling assembly 5 includes a pulley 51, a rope 52, and a cylinder 53. The cylinder 53 is located on the back side of the fixed plate 1, which can reduce the influence of the temperature of the test environment on the cylinder 53 and extend the service life of the cylinder 53. The fixed plate 1 is provided with a through hole 11, which connects the front and back sides of the fixed plate 1. Pulleys 51 are installed on the front and back sides of the fixed plate 1.

The other end of the rope 52 is connected to the cylinder 53. When the cylinder 53 retracts and pulls the rope 52, the movable plate 32 can be driven away from the pulley 21, and the support wheel 33 can tension the belt 6, so that the belt 6 can better drive the tensioning wheel 43 to rotate. More preferably, the pulley 21 and the support wheel 33 are located in the same vertical direction, so that the tensioning force applied by the support wheel 33 to the belt 6 is more uniform.

[0023] The two test assemblies 4 are arranged at intervals on the left and right, and the pulley 21 is located between the two test assemblies 4. The pulley 21 is located at the lower end between the two test assemblies 4. The wrap angle between the belt 6 and the pulley 21 is greater than 120°, so that the pulley 21 can better drive the belt 6. The test assemblies 4 on both sides can be installed with multiple different tensioning pulleys 43 for testing. The tensioning device 3 is located at the upper end of the two test assemblies 4. The belt 6 is sleeved through the pulley 21, all the tensioning pulleys 43, and the support wheel 33. When the belt 6 is sleeved, the cylinder 53 is extended to make the support wheel 33 close to the pulley 21. After the belt 6 is sleeved, the cylinder 53 is retracted, and the support wheel 33 can tension the belt 6.
