[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4As shown, this utility model is a tensile testing device for thermally insulated aluminum alloy profiles with a broken bridge structure, including a chassis assembly 1, an adjusting brake assembly 2 is provided inside the chassis assembly 1, a lifting clamp assembly 3 is provided at the top limit of the adjusting brake assembly 2, and an adjusting clamp assembly 4 is installed at the bottom of the lifting clamp assembly 3.

[0026] The adjusting clamp assembly 4 includes a positioning side plate 401. An electric telescopic rod 402 is installed on the inner wall of the positioning side plate 401. A silicone clip 403 is provided at the end of the electric telescopic rod 402. The silicone clip 403 is slidably disposed inside the limiting slide groove 405 via the limiting slide rail 406. The limiting slide groove 405 is installed on both sides of the bottom of the tray 404.

[0027] By installing the adjustable chuck assembly 4 on the device, the clamping effect can be adjusted for materials of different widths when using the device, thus ensuring the convenience of using the device.

[0028] The chassis assembly 1 includes a chassis body 101, with an installation cavity 102 inside the chassis body 101. Protective posts 103 are installed on both sides of the top of the chassis body 101, and a bottom clamp 104 is installed in the middle of the top of the chassis body 101. The bottom clamp 104 in the middle of the top of the chassis body 101 of the chassis assembly 1 is used to fix the bottom of the profile and forms an upper and lower clamping structure with the adjusting clamp assembly 4. The protective posts 103 on both sides of the top play a safety protection role during the testing process.

[0029] The regulating brake assembly 2 includes a rotating mechanism 201, which is mounted inside the mounting cavity 102 via a bracket. The output end of the rotating mechanism 201 is provided with a gear transmission box 202. The transmission end of the gear transmission box 202 is provided with a bevel gear 203 via a rotating rod. A bevel gear 204 is provided on the outside of the bevel gear 203. The bevel gear 203 and the bevel gear 204 mesh with each other. A rod is installed in the middle of the bevel gear 204, and a transmission wheel 205 is installed on the top outer wall of the rod. A transmission belt 206 is provided on the outer side of the transmission wheel 205. A driven wheel 207 is provided at the other two ends of the inner side of the transmission belt 206. A threaded rod 208 is installed on the top of the driven wheel 207.

[0030] The threaded rods 208 on both sides are symmetrically arranged and pass through the top of the chassis 101. The rotating mechanism 201 in the adjusting brake assembly 2 serves as the core power source. The output torque is adjusted by the gear transmission box 202 and then transmitted to the bevel gear 1 203 through the rotating rod. Since the bevel gear 1 203 and the bevel gear 204 mesh with each other, the torque direction is reversed and transmitted to the rod in the middle of the bevel gear 204, which drives the transmission wheel 205 at the top of the rod to rotate. The transmission wheel 205 then drives the passive wheels 207 on both sides to rotate synchronously through the transmission belt 206 with the outer limit. This causes the threaded rods 208, which are symmetrically arranged at the top of the passive wheels 207 and pass through the top of the chassis 101, to rotate accordingly.

[0031] The lifting clamp assembly 3 includes two threaded sleeves 301, which are symmetrically arranged. The threaded sleeves 301 are limited to the outside of the threaded rod 208. A connecting support plate 302 is fixedly installed between the two threaded sleeves 301. A connecting post 303 is provided at the bottom of the connecting support plate 302. An mounting plate 304 is installed at the bottom of the connecting post 303. The two threaded sleeves 301 of the lifting clamp assembly 3 are symmetrically arranged on the outside of the threaded rod 208, forming a threaded transmission structure with the threaded rod 208. When the threaded rod 208 rotates, the threaded sleeves 301 move up and down along the axial direction of the threaded rod 208, which drives the connecting support plate 302 between the two threaded sleeves 301, the connecting post 303 at the bottom of the connecting support plate 302, and the mounting plate 304 at the bottom of the connecting post 303 to move up and down synchronously.

[0032] There are two positioning side plates 401, which are symmetrically arranged. The positioning side plates 401 are respectively installed on both sides of the bottom of the mounting plate 304. The tray 404 is fixedly installed in the middle of the outer wall of the mounting plate 304. The positioning side plates 401 installed on both sides of the bottom of the mounting plate 304 move with the mounting plate 304. The electric telescopic rod 402 on the inner wall of the positioning side plate 401 can be extended and adjusted, pushing the silicone clamp 403 at the end to slide along the limiting slide groove 405 on both sides of the bottom of the tray 404, so as to clamp or release the aluminum alloy heat insulation profile.

[0033] The tensile testing device for aluminum alloy thermal insulation profiles with thermal break structure achieves tensile testing through a coordinated mechanism of "power drive - transmission adjustment - clamping test". Firstly, at the working principle level, the rotating mechanism 201 in the regulating braking assembly 2 serves as the core power source. The output torque is adjusted by the gear transmission box 202 and transmitted to the first bevel gear 203 via a rotating rod. Because the first bevel gear 203 meshes with the second bevel gear 204, the torque direction changes and is transmitted to the rod in the middle of the second bevel gear 204, causing the transmission wheel 205 at the top of the rod to rotate. The transmission wheel 205 then drives the passive wheels 207 on both sides to rotate synchronously through the transmission belt 206 with outer limit. This causes the threaded rods 207, symmetrically arranged at the top of the passive wheels 207 and penetrating the top of the housing 101, to rotate. 8 rotates accordingly; and the two threaded sleeves 301 of the lifting clamp assembly 3 are symmetrically arranged on the outside of the threaded rod 208, forming a threaded transmission structure with the threaded rod 208. When the threaded rod 208 rotates, the threaded sleeves 301 move up and down along the axial direction of the threaded rod 208, driving the connecting support plate 302 between the two threaded sleeves 301, the connecting column 303 at the bottom of the connecting support plate 302, and the mounting plate 304 at the bottom of the connecting column 303 to move up and down synchronously. The positioning side plates 401 installed on both sides of the bottom of the mounting plate 304 move with the mounting plate 304. The electric telescopic rod 402 on the inner wall of the positioning side plate 401 is telescopically adjustable, pushing the silicone clamp 403 at the end to slide along the limiting slide groove 405 on both sides of the bottom of the tray 404, realizing the clamping or releasing of the aluminum alloy heat insulation profile. Meanwhile, the bottom clamp 104 in the middle of the top of the chassis 101 of the chassis assembly 1 is used to fix the bottom of the profile, forming an upper and lower clamping structure with the adjusting clamp assembly 4. The protective posts 103 on both sides of the top provide safety protection during the test. After the adjusting clamp assembly 4 clamps the top of the profile and the bottom clamp 104 fixes the bottom of the profile, the adjusting brake assembly 2 drives the lifting clamp assembly 3 to move upward slowly, so that the adjusting clamp assembly 4 applies an upward pulling force to the profile. The tensile performance test is completed by monitoring the change of the pulling force value. In the specific workflow, the equipment is first initialized and the profile is placed. The status of each component is checked to ensure that the chassis 101 is placed stably, and the turntable 201 and gear transmission box 202 are in standby state. The profile to be tested is then placed in the... At the top center of the housing 101, align the bottom of the profile with the bottom clamp 104 and initially fix it; then adjust the positioning and clamping of the clamp assembly 4, start the rotating machine 201, and drive the threaded rod 208 to rotate through the transmission of the gear transmission box 202, bevel gear one 203, bevel gear two 204, transmission wheel 205, transmission belt 206, and passive wheel 207. The threaded rod 208 drives the threaded sleeve 301, connecting support plate 302, connecting column 303, and mounting plate 304 of the lifting clamp assembly 3 to move downward until the silicone clamp 403 corresponds to the top two sides of the profile. Then, start the electric telescopic rod 402 to push the silicone clamp 403 to slide along the limiting slide groove 405 towards the profile until it tightly clamps the top of the profile, and then close the electric telescopic rod 402.Next, a tensile test is performed. The rotation direction of the rotating mechanism 201 is adjusted to cause the threaded rod 208 to rotate in the opposite direction, driving the lifting clamp assembly 3 and the adjusting clamp assembly 4 to slowly move upward. The adjusting clamp assembly 4 applies an upward pulling force to the top of the profile, while the bottom clamp 104 fixes the bottom of the profile to form a stable pulling force. At the same time, the tensile force value is monitored in real time by an external force measuring device, and the stress state of the profile is recorded until the preset test requirements are met. Finally, the test ends and is reset. The rotating mechanism 201 is turned off, and the electric telescopic rod 402 is started to cause the silicone clamp 403 to slide in the opposite direction to release the top of the profile. The rotating mechanism 201 is started again to reset the lifting clamp assembly 3 and the adjusting clamp assembly 4 downward to the initial position. The tested profile is removed, the equipment surface is cleaned, and the integrity of each component is checked to prepare for the next test.
