When we carry them out, generally, they are carried manually. Due to the weight of the power amplifier and the weight of the storage box itself, manual handling will be strenuous and cause certain inconvenience to our travel. Summary of the Utility Model

[0003] In order to improve the power amplifier storage box that cannot save physical strength during handling and lacks portability during travel, the present application provides a power amplifier storage box.

[0004] A power amplifier storage box provided by the present application adopts the following technical solutions:

[0005] A power amplifier storage box includes a storage box body. A cushion block is fixedly provided at the lower part of the storage box body, and a rotary locking mechanism is provided below the cushion block.

[0006] The rotary locking mechanism includes a semi-circular plate fixedly provided at the lower part of the cushion block. A smooth S-shaped chute is provided on one side of the semi-circular plate. A slidable first slide plate is sleeved on the outer surface of the S-shaped chute. A slidable second slide plate is sleeved on the outer surface of the first slide plate. A first square rod is fixedly provided on one side of the second slide plate. Two limiting blocks are symmetrically fixedly provided on the upper part of the first square rod, and the limiting blocks are inserted into limiting holes.

[0007] By adopting the above technical solutions, the smooth S-shaped chute can make the first slide plate and the second slide plate slide more smoothly. The first square rod is fixedly connected to the second slide plate, and the rotation of the first square rod can drive the second slide plate to rotate on the S-shaped chute.

[0008] Preferably, the rotary locking mechanism further includes two symmetrically arranged first through grooves provided on the side walls of both sides of the first slide plate. A first limiting column is slidably arranged in the inner cavity of the first through groove, and the first limiting column movably penetrates through the side walls of both sides of the second slide plate.

[0009] By adopting the above technical solutions, the first limiting column is slidably arranged in the first through groove, driving the second slide plate to slide in the first through groove together.

[0010] Preferably, a spring is fixedly provided between the lower part of the first slide plate and the inner cavity surface of the lower part of the second slide plate.

[0011] By adopting the above technical solution, a spring fixed between the first slide plate and the second slide plate can play a buffering role and the spring has a reaction force when compressed, which can make the movement between the first slide plate and the second slide plate smoother.

[0012] Preferably, a strip-shaped groove is formed in the upper part of the first square rod, and the semi-circular piece is located in the strip-shaped groove and slides relative to each other.

[0013] By adopting the above technical solution, the strip-shaped groove can play a good limiting and protective role during the movement of the semi-circular piece.

[0014] Preferably, a limiting groove is formed in the lower part of the first square rod, and a second limiting post is movably arranged through the lower part of the limiting groove, and the second limiting post movably penetrates through one end of the second square rod.

[0015] By adopting the above technical solution, the second limiting post movably penetrates through the first square rod and the second square rod, enabling the first square rod and the second square rod to rotate relative to each other, and providing a good limiting effect when the first square rod and the second square rod rotate.

[0016] Preferably, one end of the second square rod is rotatably connected to the limiting groove, a second through groove for the second limiting post to slide is formed in the middle of one side of the second square rod, a pull rod is fixed on the side of the second square rod away from the second through groove, and a handle for easy hand holding is fixedly penetrated through one side of the pull rod.

[0017] By adopting the above technical solution, the second through groove enables the second square rod to be inserted into the first square rod for limiting and fixing when the second square rod and the first square rod rotate to the same straight line.

[0018] Preferably, a tripod that opens and closes like an umbrella is slidably arranged in the middle of the pull rod.

[0019] By adopting the above technical solution, the tripod can provide good stability for the device.

[0020] Preferably, reed pieces for limiting are fixed at the corner positions on both sides of the inner cavity of the S-shaped chute.

[0021] By adopting the above technical solution, the reed pieces can provide a certain limiting effect for the first limiting post after it stops moving in the S-shaped chute, and do not restrict the movement of the first limiting post.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Use the handle to rotate the pull rod and the second square rod at a certain inclination angle in the limiting groove, then transmit the pulling force to the rotary locking mechanism, and then to the cushion block and the storage box body, so that the storage box body can be easily pulled;

[0024] 2. By stretching out the tripod, then rotating the second square rod and pushing the second square rod into the inner cavity of the limiting groove, after the second square rod is completely attached to the inner cavity of the limiting groove and is mutually limited, lift the storage box body upward to release the limit of the first limiting post and the S-shaped chute. Then, the first square rod will drive the second sliding plate and the first sliding plate to rotate together, and the first limiting post will move in the inner cavity of the S-shaped chute from the first limiting position to the second limiting position following the movement of the second sliding plate. At this time, the semi-circular piece rotates in the strip-shaped groove, so that after the semi-circular piece and the cushion block are perpendicular to each other through the first square rod, gently lower the storage box body. After the limiting block and the limiting hole are mutually attached and limited, the tripod can support the storage box body, making the device more convenient to use.

[0036] The following is combined with the attached Figure 1-8A further detailed description of the present application is provided.

[0037] An embodiment of the present application discloses a power amplifier storage box.

[0038] Embodiment 1

[0039] Referring to Figure 1 , a power amplifier storage box includes a portable and movable storage box body 1, and the middle part of the lower surface of the storage box body 1 is fixedly welded to the upper surface of the cushion block 2.

[0040] Through the above setting, the cushion block 2 fixed in the middle of the lower surface of the storage box body 1 can play a role in maintaining balance for supporting the storage box body 1, and the cushion block 2 can also play a role in connecting and isolating the storage box body 1 from the remaining structure of the device.

[0041] Referring to Figure 3 , 5 , 7, 8, a rotary locking mechanism 3 is provided in the middle of the lower surface of the cushion block 2. The rotary locking mechanism 3 includes a semi-circular plate 31 fixedly welded to the middle of the lower surface of the cushion block 2. An S-shaped chute 32 is provided on one side of the semi-circular plate 31. The surfaces of the S-shaped chute 32 and the semi-circular plate 31 are both smooth surfaces. On both sides of the inner surface of the S-shaped chute 32, the lower surfaces of two symmetrically arranged reed pieces 10 are fixedly connected, and the reed pieces 10 are fixedly arranged at the corner positions of the S-shaped chute 32 for limiting functions as Figure 8 shown.

[0042] The outer surface of the S-shaped chute 32 fits with the inner surface of the slidable first slide plate 33. The first slide plate 33 is sleeved outside the S-shaped chute 32. The outer surface of the first slide plate 33 fits with the inner surface of the second slide plate 35. The second slide plate 35 is also sleeved outside the slidable first slide plate 33. The first slide plate 33 and the second slide plate 35 have the same shape. The surface of the second slide plate 35 away from the first slide plate 33 is fixedly connected to one side surface of the first square rod 310. On both sides of the upper surface of the first square rod 310, the lower surfaces of two symmetrically arranged limit blocks 36 are fixedly connected. The shape and size of the limit blocks 36 are the same as those of the holes of the limit holes 9, and the limit blocks 36 are inserted into the limit holes 9 to achieve mutual limitation.

[0043] Both side walls on both sides of the first slide plate 33 are provided with first through grooves 39, and the two first through grooves 39 are symmetrically arranged and both penetrate through the side walls on both sides of the first slide plate 33, so that the two first through grooves 39 can communicate with each other. The inner cavity surface of the first through groove 39 is attached to and slidably arranged with the outer surface of the first limiting column 34. The two ends of the first limiting column 34 are movably penetrated through the side walls on both sides of the second slide plate 35. Therefore, both the first slide plate 33 and the second slide plate 35 are movably penetrated by the first limiting column 34, and the second slide plate 35 can reciprocate on the surface of the first slide plate 33 through the first limiting column 34. One end of a spring 38 is fixedly connected to the middle of the lower surface of the first slide plate 33, and the other end of the spring 38 away from the first slide plate 33 is fixedly connected to the inner cavity surface of the lower part of the second slide plate 35.

[0044] A strip-shaped groove 37 corresponding to the semi-circular piece 31 is provided in the middle of the upper end of the first square rod 310, and the width of the strip-shaped groove 37 is 1-2 mm larger than the thickness of the semi-circular piece 31, so that the semi-circular piece 31 can slide smoothly on the inner cavity surface of the strip-shaped groove 37.

[0045] Through the above settings, when the first square rod 310 moves longitudinally, it drives the first limiting column 34 to disengage from the limit of the reed 10 in the S-shaped chute 32, and at the same time drives the second slide plate 35 to move longitudinally. When the first square rod 310 rotates, it drives the second slide plate 35 to rotate. The rotation of the second slide plate 35 can drive the first slide plate 33 to rotate through the first limiting column 34. When the first limiting column 34 moves to another limiting position in the S-shaped chute 32, the positions of the semi-circular piece 31 and the cushion block 2 are exactly at a 90-degree angle to the first square rod 310. Push the first square rod 310 to make the first limiting column 34 and the S-shaped chute 32 limit each other, and the limiting block 36 is inserted into the inner cavity of the limiting hole 9 for further limiting.

[0046] Refer to Figure 3 、 4, 6. A limiting groove 12 is formed in the lower part of the first square rod 310 away from the cushion block 2. The lower inner walls on both sides of the limiting groove 12 are movably penetrated by the second limiting posts 8. The middle part of the second limiting posts 8 is movably penetrated by one end of the second square rod 4. Therefore, one end of the second square rod 4 is connected to the limiting groove 12 through the second limiting posts 8 and can rotate relative to each other. The surface of the second square rod 4 connected to the limiting groove 12 is semicircular. A square opening is formed in the inner wall of the limiting groove 12 on the same side as the second sliding plate 35, so that the second square rod 4 can rotate in the limiting groove 12 without being affected. A second through groove 11 is formed in the middle of the side of the second square rod 4 connected to the limiting groove 12. The second through groove 11 penetrates the second square rod 4 and allows the second limiting posts 8 to slide in the inner cavity of the second through groove 11. The surface of the second square rod 4 away from the second through groove 11 is fixedly connected to one side surface of the pull rod 6. A handle 7 convenient for holding is fixedly penetrated through the side of the pull rod 6 away from the second square rod 4. The middle part of the pull rod 6 is slidably arranged with a tripod 5 that opens and closes like an umbrella.

[0047] Through the above settings, the second square rod 4 can rotate and be limited in the limiting groove 12 through the second limiting posts 8. The second through groove 11 can push the second square rod 4 into the inner cavity of the limiting groove 12 for limiting and fixing. The rotation of the second square rod 4 can drive the tripod 5, the pull rod 6, and the handle 7 to rotate accordingly. When the tripod 5 is opened, it can vertically support the second square rod 4, the limiting groove 12, and the entire device.

[0048] The implementation principle of an embodiment of a power amplifier storage box in this application is as follows: When it is necessary to carry this device out for work, just pull the handle 7. The handle 7 will drive the pull rod 6 and the second square rod 4 to rotate at a certain inclination angle in the limiting groove 12, and then transmit the pulling force to the rotary locking mechanism 3, and then to the cushion block 2 and the storage box body 1, so that the storage box body 1 can be easily pulled and move along with the staff.

[0049] When we reach the destination, we only need to extend the tripod 5, then rotate the second square rod 4 so that the second square rod 4 is in the same straight line as the limiting groove 12, and then push the second square rod 4 into the inner cavity of the limiting groove 12. After the second square rod 4 is completely attached to the inner cavity of the limiting groove 12 and they are mutually limited, lift the storage box body 1 upward to release the limitation of the first limiting column 34 and the S-shaped sliding groove 32. Then the first square rod 310 will drive the second sliding plate 35 and the first sliding plate 33 to rotate together, and the first limiting column 34 will move from the first limiting position to the second limiting position in the inner cavity of the S-shaped sliding groove 32 following the movement of the second sliding plate 35. At this time, the semi-circular piece 31 rotates in the strip-shaped groove 37, so that after the semi-circular piece 31 and the cushion block 2 are perpendicular to each other at 90 degrees through the first square rod 310, gently lower the storage box body 1. After the limiting block 36 and the limiting hole 9 are mutually attached and limited, the tripod 5 will support the storage box body 1, making it more convenient for the staff to use the power amplifier device. After the work is completed, just fold up the device according to the reverse steps.

[0050] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
