Detailed Embodiment

[0027] The following will Figures 1-5 further describe the present application in detail with reference to the attached

[0028] An embodiment of the present application discloses an aging rack. Referring to Figures 1-3 , an aging rack includes a frame body 1, a push-pull clamp 2 and a profiling module 3.

[0029] A number of storage platforms 11 are provided on the frame body 1. The number of the storage platforms 11 is preferably 4, and the storage platforms 11 are arranged in parallel at intervals. The push-pull clamp 2 is installed on the upper end surface of the storage platform 11. The push-pull clamp 2 includes a positioning frame 21, a rotating handle 22 and a moving rod 23. The bottom end of the positioning frame 21 is fixedly connected to the upper end surface of the storage platform 11. A chute 211 is formed at the top end of the positioning frame 21 facing away. The rotating handle 22 is located at one end of the chute 211. The bottom end of the rotating handle 22 is rotatably connected to the groove wall of the chute 211. The moving rod 23 is arranged in the chute 211, and one end of the moving rod 23 is fixedly connected to the rotating handle 22. The profiling module 3 includes a positioning plate 31 and a connecting plate 32. One side of the positioning plate 31 is fixedly connected to the side of the moving rod 23 facing away from the rotating handle 22. The connecting plate 32 is connected to the other side of the positioning plate 31. The connecting plate 32 can move relative to the positioning plate 31. A number of connecting joints 33 are connected to the side of the connecting plate 32 facing away from the positioning plate 31. The power amplifier is located on the moving path of the connecting plate 32, and the connecting joints 33 are electrically connected to the power amplifier.

[0030] When aging the power amplifier, first place the power amplifier on the storage platform 11, and then move the rotating handle 22. The rotating handle 22 drives the moving rod 23 to move in the chute 211, so that the positioning plate 31 and the connecting plate 32 move, and the connecting joints 33 on the connecting plate 32 are aligned with and inserted into the interfaces on the power amplifier. When the connecting joints 33 on the connecting plate 32 are not completely aligned with the interfaces on the power amplifier, the connecting plate 32 will move under the action of the cooperation force provided by the rotating handle 22, so that the connecting joints 33 are aligned with the interfaces of the power amplifier, realizing the connection between the power amplifier and the aging rack. The probability of damage to the power amplifier interface is reduced when the power amplifier is connected to the aging rack.

[0031] Refer to Figure 1 and Figure 2 , an aviation plug 5 is arranged on the side of the connecting plate 32 facing away from the connecting joints 33. The aviation plug 5 is connected to the wire connected to the connecting joints 33 on the connecting plate 32. The aviation plug 5 can control the simultaneous connection and disconnection of the wires connected to the connecting joints 33, so as to be able to simulate the situation where all functional components on the power amplifier are powered on simultaneously during actual use.

[0032] Refer to Figure 2 , a guide cylinder 24 is fixedly connected to the side of the positioning frame 21 facing away from the rotating handle 22. The guide cylinder 24 is located in the chute 211. The cylinder wall of the guide cylinder 24 abuts against the groove wall of the chute 211. The diameter direction of the guide cylinder 24 is the same as the direction of the chute 211. One section of the moving rod 23 is located in the guide cylinder 24 and is slidably connected to the inner wall of the guide cylinder 24.

[0033] The guide cylinder 24 can limit the moving direction of the moving rod 23 when the rotating handle 22 drives the moving rod 23 to move, reducing the probability of the moving rod 23 shaking during movement and facilitating the connection between the power amplifier and the aging rack.

[0034] Referring to Figure 2 and Figure 3 , on one side of the positioning plate 31 facing the connecting plate 32, a first connection hole 311 is opened. On one side of the connecting plate 32 facing the positioning plate 31, a second connection hole 321 is opened. The positioning plate 31 is fixedly connected with a connecting rod 34. The diameter of the second connection hole 321 is larger than the diameter of the connecting rod 34. One end of the connecting rod 34 is fixedly connected to the hole wall of the first connection hole 311, and the other end of the connecting rod 34 is slidably connected to the hole wall of the second connection hole 321. The second connection hole 321 is a hole with a small outlet and a large interior. The diameter of the end of the connecting rod 34 located inside the second connection hole 321 is larger than the diameter of the outlet of the second connection hole 321. A return spring 35 is sleeved on the connecting rod 34, and both ends of the return spring 35 respectively abut against the positioning plate 31 and the connecting plate 32.

[0035] The connecting rod 34 connects the positioning plate 31 and the connecting plate 32, and the return spring 35 keeps a gap between the positioning plate 31 and the connecting plate 32. When the connection joint 33 on the connecting plate 32 is connected to the power amplifier, if there is a gap between the connection joint 33 and the interface of the power amplifier, the connecting plate 32 can move through the gap between the second connection hole 321 and the connecting rod 34, and the return spring 35 contracts, facilitating the movement of the connecting plate 32, thereby reducing the probability of damaging the interface of the power amplifier when the connection joint 33 on the connecting plate 32 is connected to the upper interface of the power amplifier.

[0036] Referring to Figure 1 and Figure 4 , the storage platform 11 is provided with a plurality of positioning holes 111. Screws can pass through the positioning holes 111 to position the power amplifier on the storage platform 11. Positioning jigs 4 are arranged around the positioning holes 111, and the positioning jigs 4 are fixedly connected to the upper surface of the storage platform 11. When dealing with power amplifiers of different sizes, positioning holes 111 can be opened at different positions on the storage platform 11, and the positioning jigs 4 can be re-fixed to the storage platform 11, thereby realizing the positioning of power amplifiers of different sizes.

[0037] Referring to Figure 1 , at the top of the frame body 1, a power supply storage chamber 6 is provided. A plurality of power supplies are placed in the power supply storage chamber 6. The aviation plug 5 is electrically connected to the power supply. A plurality of heat dissipation holes 61 are opened on the side wall of the power supply storage chamber 6.

[0038] The power supply can supply power to the aviation plug 5, thus meeting the aging requirements of the aging rack. The heat dissipation holes 61 of the power supply storage chamber 6 can facilitate the heat dissipation of the power supply and reduce the probability of the power supply being damaged due to high temperature.

[0039] Referring to Figure 1 and Figure 5, a moving wheel 7 is provided at the bottom end of the frame body 1. A locking piece 71 is connected to the side wall of the moving wheel 7, and the locking piece 71 can frictionally abut against the moving wheel 7. The moving wheel 7 at the bottom end of the frame body 1 facilitates the transportation of the aging rack. After the aging rack is transported to the required position, the locking piece 71 can lock the moving wheel 7, reducing the probability that the movement of the aging rack affects the aging of the power amplifier.

[0040] The implementation principle of an aging rack in an embodiment of the present application is as follows: When aging the power amplifier, place the power amplifier on the placement platform of the aging rack, and then drive the rotation handle 22, so that the rotation handle 22 drives the moving rod 23 to move. Under the action of the moving rod 23, the positioning plate 31 and the connecting plate 32 move towards the power amplifier, and the connecting joint 33 on the connecting plate 32 abuts against the interface of the power amplifier, realizing the connection between the power amplifier and the aging rack. When the connecting joint 33 on the connecting plate 32 and the interface on the power amplifier are not completely aligned, the moving plate can move under the action of the cooperation force provided by the rotating wrench, so that the connecting joint 33 on the connecting plate 32 is aligned with the interface on the power amplifier, reducing the probability of damage to the power amplifier interface when the power amplifier is connected to the aging rack.

[0041] The above are all preferred embodiments of the present application. Without restricting the protection scope of the present application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
