The two ends of the two clamping end plates 3 distributed up and down are respectively inserted between the bottom plate 21 and the top plate 22 and are located on the inner side of the two threaded rods 23. The two ends of the clamping end plate 3 located at the bottom are tightly attached to the upper end surfaces of the two bottom plates 21. The limiting seats 4 are respectively arranged at the two ends of the top of the clamping end plate 3 located at the top, and the two top plates 22 are respectively snap-fitted and installed on the top of the limiting seats 4.

[0023] In one embodiment, when using the loading frame 1 to clamp the radiator prototype, the bottom plate 21 can be placed on the sealing machine first, so that the two bottom plates 21 are respectively located at the bottom ends of the radiator prototype, and then one of the clamping end plates 3 is placed on the upper end surfaces of the two bottom plates 21, so that the clamping end plate 3 is located directly below the radiator prototype, and then the two threaded rods 23 are installed on the top of the bottom plate 21 through the threaded groove 211, so that the two threaded rods 23 are respectively located on both sides of the radiator prototype, and then the other clamping end plate 3 is placed between the two threaded rods 23, so that the clamping end plate 3 is tightly attached to the upper end surface of the radiator prototype, and then the two limiting seats 4 are placed on the top ends of the clamping end plates 3, and the top plate 22 located above the limiting seat 4 is slid on the outside of the threaded rod 23 through the through hole 221, so that the top plate 22 is engaged with the top of the limiting seat 4 through the groove 402, and the limiting seat 4 is pressed against the upper end surface of the clamping end plate 3 through the pressing plate 42, and finally, upward. The radiator 21 is then clamped in the position where it is held in place by the two end plates 3. The radiator 21 is then clamped in the position where it is held in place by the two end plates 3.

[0024] In one embodiment, since the internal thread of the fastening nut 24 is in opposite direction to the internal thread of the thread groove 211, when installing the threaded rod 23 on the base plate 21, the threaded rod 23 can be first installed in the thread groove 211, and then the fastening nut 24 on the outer wall of the threaded rod 23 is screwed to make the fastening nut 24 close to the upper end surface of the base plate 21. The fastening nut 24 tightens the threaded rod 23 on the base plate 21 to prevent the threaded rod 23 from rotating, thereby avoiding the threaded rod 23 from falling off the base plate 21 due to rotation, thereby ensuring the stability of the installation of the threaded rod 23.

[0025] In one embodiment, when clamping and transporting radiator prototypes of different models, the clamping end plate 3 can be replaced first to make the clamping end plate 3 compatible with the model of the heat sink on the radiator prototype, and then the distance between the two clamping frames 2 can be adjusted, and the clamping end plate 3 can be placed in the two clamping frames 2 to clamp the radiator prototypes of different widths, and then the top plate 22 can be slid on the outer wall of the threaded rod 23 through the through hole 221, and the height of the top plate 22, the limit seat 4 and the clamping end plate 3 located above can be adjusted to change the distance between the two clamping end plates 3 so that the distance between the two clamping end plates 3 can be compatible with the height of the radiator prototype, so that radiator prototypes of different models can be clamped in the loading frame 1, and the size of the loading frame 1 can be adjusted according to the model of the radiator so that the loading frame 1 can be compatible with the model of the radiator, thereby realizing the clamping and transportation of radiator prototypes of various models.

[0026] Combination Figure 3 , Figure 4 and Figure 5 As shown, a hollow groove 401 is opened inside the limit seat 4, an inner plate 41 is arranged on the inner wall of the hollow groove 401, a pressure plate 42 is arranged at the bottom of the limit seat 4, and positioning rods 43 are arranged at the top of the pressure plate 42 and at positions corresponding to the four corners of the inner plate 41. The end of the positioning rod 43 away from the pressure plate 42 is inserted into the hollow groove 401 and extends through the inner plate 41 to the top thereof, and an annular limiting plate 44 is arranged on the end of the positioning rod 43 located above the inner plate 41, and a buffer spring 45 is arranged around the outer wall of the positioning rod 43 between the pressure plate 42 and the inner plate 41.

[0027] In one embodiment, when the limit seat 4 is used to clamp the end plate 3, the limit seat 4 can be pressed tightly against the upper end surface of the clamping end plate 3 through the pressure plate 42, and the positioning rods 43 installed at the four corners of the pressure plate 42 can slide upward in the empty groove 401, and then the pressure plate 42 presses the buffer spring 45 surrounding the outside of the positioning rod 43 to deform, so that the buffer spring 45 buffers the force of the pressure plate 42 pressing the clamping end plate 3, thereby avoiding the situation where the pressure plate 42 presses the clamping end plate 3 and damages the heat sink due to the large pressing force of the pressure plate 42, thereby protecting the heat sink.

[0028] In one embodiment, when the end plate 3 is clamped by the pressure plate 42, the positioning rods 43 installed at the four corners of the pressure plate 42 extend to the top of the inner plate 41 through the sliding holes 411, so that the positioning rods 43 will not interfere with the displacement of the pressure plate 42, which facilitates the use of the pressure plate 42. In one embodiment, when the limit seat 4 is not used, since the end surface area of ​​the annular limit plate 44 is larger than the opening area of ​​the sliding hole 411, the annular limit plate 44 can limit the pressure plate 42 to prevent the pressure plate 42 from detaching from the limit seat 4, which facilitates the use of the limit seat 4.

[0029] The working principle of the utility model is as follows: when the radiator prototype on the transport sealing machine, the bottom plate 21 can be placed on the sealing machine first, so that the two bottom plates 21 are respectively located at the bottom two ends of the radiator prototype, and then one of the clamping end plates 3 is placed on the upper end surfaces of the two bottom plates 21, so that the clamping end plate 3 is located directly below the radiator prototype, and then the two threaded rods 23 are installed on the top of the bottom plate 21 through the threaded groove 211, so that the two threaded rods 23 are respectively located on both sides of the radiator prototype, and then the other clamping end plate 3 is placed between the two threaded rods 23, so that the clamping end plate 3 is tightly attached to the upper end surface of the radiator prototype, and then the two limiting seats 4 are placed on the top two ends of the clamping end plates 3, and the top plate 22 located above the limiting seat 4 is slid on the outside of the threaded rod 23 through the through hole 221, so that the top plate 22 is engaged with the top of the limiting seat 4 through the groove 402, and the limiting seat 4 is pressed against the upper end surface of the clamping end plate 3 through the pressing plate 42, and finally, The threaded rod 23 is pulled up to drive the bottom plate 21 installed thereon and the clamping end plate 3 on the bottom plate 21 to move upward, so that the bottom plate 21 presses the clamping end plate 3 against the lower end surface of the radiator prototype, and then the limiting nut 25 is screwed on the outer wall of the threaded rod 23 and pressed against the upper end surface of the top plate 22, to limit the position of the top plate 22, the limiting seat 4 and the clamping end plate 3 after the adjustment position, and clamp the radiator prototype between the two clamping end plates 3 for limiting. In this way, the assembly and clamping work of the loading rack 1 is completed, and the loading rack 1 can be assembled on the sealing machine, and the radiator prototype is clamped in the loading rack 1 for transportation, so as to prevent the aluminum plate heat sinks on the radiator prototype from scattering and falling off, and to avoid the damage of the radiator prototype due to the scattering and falling of the aluminum plate heat sinks when transporting the radiator prototype, which facilitates the subsequent processing of the radiator prototype and realizes the transportation and protection of the radiator prototype.
