Description

Technical Field

[0001] This utility model relates to the field of audio technology, and in particular to a portable Bluetooth speaker. Background Technology

[0002] A Bluetooth speaker is a portable speaker that receives and plays audio signals wirelessly via Bluetooth technology. It has the advantages of simple operation, strong compatibility, and integrated functions. Bluetooth speakers free users from the constraints of traditional speakers that require audio cables, allowing users to easily play music through their mobile phones and computers.

[0003] When users need to move Bluetooth speakers, traditional Bluetooth speakers have hooks on them, requiring users to wrap the power cord directly around the hooks for storage. When moving the speaker, due to the large amount of shaking, the power cord is easy to fall off the hook, making it inconvenient to carry and move the speaker. At the same time, the power cord dragging on the ground will cause wear and tear, and users are also prone to tripping over the power cord, which may lead to injury. Therefore, a portable Bluetooth speaker is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a portable Bluetooth speaker.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A portable Bluetooth speaker includes a speaker body. A plug is electrically connected to one side of the speaker body via a power cord. A U-shaped frame is provided on one side of the speaker body. Through holes are provided on both sides of the U-shaped frame. A rotating rod is rotatably connected to the inside of the through holes. Through slots are provided on both sides of the U-shaped frame. A sliding rod is fixedly connected to the inside of the through slot. A mounting sleeve is slidably connected to the outside of the sliding rod. A spring is fixedly connected to one side of the mounting sleeve. One end of the spring is fixedly connected to the inside of the through slot. A crossbar is fixedly connected between the two mounting sleeves.

[0006] By adopting the above technical solution, and by setting up a U-shaped frame, a rotating rod, a crossbar, and a spring, when the user does not need to use the power cord, they can pull the crossbar to cause the mounting sleeve to compress the spring, and then wrap the power cord around the outside of the rotating rod. When the crossbar is released, the spring's rebound potential energy will push the mounting sleeve to cause the crossbar to compress the power cord wrapped around the outside of the rotating rod, thus fixing the power cord to the outside of the rotating rod, thereby storing the power cord and making the Bluetooth speaker more portable. This also prevents the power cord from dragging on the ground and causing wear, and also prevents pedestrians from tripping over the power cord.

[0007] Preferably, an elastic lever is fixedly connected to the outside of the rotating rod, and the elastic lever is L-shaped.

[0008] By adopting the above technical solution, and by setting an elastic lever with an L-shaped elastic lever, the power cord can be clamped between the elastic lever and the rotating rod. When the user needs to store the power cord, the power cord near the plug end can be clamped with the elastic lever. At this time, the plug is fixed on the outside of the rotating rod. Rotating the rotating rod can drive the elastic lever and the plug to rotate. As the rotating rod rotates, the power cord is wrapped around the outside of the rotating rod, eliminating the need for manual winding.

[0009] Preferably, a knob is fixedly connected to one end of the rotating rod, and an anti-slip rubber pad is provided on the outside of the knob.

[0010] By adopting the above technical solution and by setting a knob and an anti-slip rubber pad, it is more convenient for users to turn the knob and their hands are less likely to slip.

[0011] Preferably, a pull rod is fixedly connected to one end of the crossbar, and a circular plate is fixedly connected to one end of the pull rod, the size of which is larger than the size of both ends of the pull rod.

[0012] By adopting the above technical solution, and by setting a pull rod and a circular plate with the size of the circular plate being larger than the size of both ends of the pull rod, it is convenient for users to pinch the circular plate and push the pull rod to move the mounting sleeve and crossbar, thereby storing the power cord.

[0013] Preferably, a guide plate is fixedly connected to the side of the speaker body, and a guide groove is provided on the side of the U-shaped frame near the speaker body. The U-shaped frame is slidably sleeved on the outside of the guide plate through the guide groove. A plurality of threaded grooves are provided on one side of the guide plate, and a threaded rod is threadedly connected to one side of the U-shaped frame. The threaded grooves are adapted to the threaded rod.

[0014] By adopting the above technical solution, and by setting a guide plate, threaded hole and threaded groove, the user can unscrew the threaded rod, move the U-shaped frame, and after moving the U-shaped frame to the appropriate position, screw the threaded rod into another threaded groove, thereby fixing the U-shaped frame on the guide plate for easy storage of the power cord. This allows the user to easily adjust the position of the U-shaped frame according to the length of the power cord.

[0015] Preferably, both the guide plate and the guide groove have T-shaped cross-sections, and the guide plate and the guide groove are compatible.

[0016] By adopting the above technical solution, and by setting both the guide plate and the guide groove to have T-shaped cross sections and matching them, the U-shaped frame can only move up and down on the outside of the guide plate and cannot move forward, backward, left, or right. When adjusting the position of the U-shaped frame, the U-shaped frame is not easy to fall off the guide plate.

[0017] Preferably, a handle is fixedly connected to the top of the speaker body, and casters are installed at the four corners of the bottom of the speaker body.

[0018] By adopting the above technical solution and by setting up a handle and casters, it is easier and more convenient to move the Bluetooth speaker, making the Bluetooth speaker more portable.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting up a U-shaped frame, rotating rod, crossbar, spring, and mounting sleeve, users can pull the crossbar to cause the mounting sleeve to compress the spring, rotate the rotating rod to wrap the power cord around the outside of the rotating rod, and release the crossbar. The spring's rebound potential energy pushes the mounting sleeve to push the crossbar against the power cord, fixing the power cord to the outside of the rotating rod and storing the power cord. When users move and transport the audio equipment, the power cord is less likely to scatter, making it more portable and preventing the power cord from dragging on the ground and causing wear. It can also prevent users from tripping over the power cord.

[0020] 2. By setting up guide plates, threaded grooves, and threaded rods, when the power cord of the Bluetooth speaker is short, the user can unscrew the threaded rod to move the U-shaped frame to the appropriate position, and screw the threaded rod into another threaded groove. At this time, the U-shaped frame is fixed in the designated position, so that the user can store and fix the power cord even when it is short. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-3 A portable Bluetooth speaker includes a speaker body 1. A plug 12 is electrically connected to one side of the speaker body 1 via a power cord 11. A U-shaped frame 2 is provided on one side of the speaker body 1. Through holes are provided on both sides of the U-shaped frame 2. A rotating rod 3 is rotatably connected to the inside of the through holes. A knob 10 is fixedly connected to one end of the rotating rod 3. An anti-slip rubber pad is provided on the outside of the knob 10. The knob 10 and the anti-slip rubber pad can facilitate the user to rotate the rotating rod 3 without slipping. An elastic lever 4 is fixedly connected to the outside of the rotating rod 3. The elastic lever 4 is L-shaped. The elastic lever 4 allows the user to fix the end of the power cord 11 near the plug 12 to the outside of the rotating rod 3, which is convenient for the user to wrap the power cord 11 around the outside of the rotating rod 3 later. Both sides of the U-shaped frame 2 have through slots. A slide rod 5 is fixedly connected to the inside of the through slot, and an installation sleeve 6 is slidably connected to the outside of the slide rod 5. A spring 8 is fixedly connected to one side of the installation sleeve 6, and one end of the spring 8 is fixedly connected to the inside of the through slot. A crossbar 7 is fixedly connected between the two installation sleeves 6. A pull rod 9 is fixedly connected to one end of the crossbar 7, and a circular plate is fixedly connected to one end of the pull rod 9. The size of the circular plate is larger than the size of both ends of the pull rod 9. The circular plate and the pull rod 9 make it convenient for the user to pinch the circular plate to move the pull rod 9, the installation sleeve 6 and the crossbar 7. When it's necessary to store the Bluetooth speaker's power cord 11, pull open the elastic lever 4, securing the end of the power cord 11 near the plug 12 inside the elastic lever 4. Pull the lever 9 to move the mounting sleeve 6 and the crossbar 7 away from the rotating rod 3. During this movement, the mounting sleeve 6 will compress the spring 8. When the distance between the crossbar 7 and the rotating rod 3 is large enough, stop moving the lever 9. Then, turn the selector knob 10. The knob 10's rotation causes the rotating rod 3, the elastic lever 4, and the plug 12 to rotate. As the plug 12 rotates outside the rotating rod 3, the power cord 11 is wrapped around the outside of the rotating rod 3. When the rotating rod 3 and the speaker... When the power cord 11 between the speaker body 1 is taut, stop turning the knob 10 and release the lever 9. Under the action of the rebound potential energy of the spring 8, the mounting sleeve 6 and the crossbar 7 will move towards the rotating rod 3. When the crossbar 7 contacts the power cord 11 wrapped around the outside of the rotating rod 3, the crossbar 7 will continue to squeeze the power cord 11 under the action of the spring 8, thereby fixing the power cord 11 to the outside of the rotating rod 3 and storing the power cord 11. This makes the Bluetooth speaker more portable and also prevents the power cord 11 and plug 12 from dragging on the ground for a long time, causing wear and tear. It also prevents users from tripping over the power cord 11.

[0025] Reference Figure 1 and Figure 5A guide plate 13 is fixedly connected to the side of the speaker body 1. A U-shaped frame 2 has a guide groove on the side near the speaker body 1. The U-shaped frame 2 slides on the outside of the guide plate 13 through the guide groove. Both the guide plate 13 and the guide groove have T-shaped cross sections. The guide plate 13 and the guide groove are adapted to each other. When the U-shaped frame 2 slides on the outside of the guide plate 13, it can only move up and down and will not wobble back and forth or left and right, making the operation more stable. Several threaded grooves 14 are opened on one side of the guide plate 13. A threaded rod 15 is threadedly connected to one side of the U-shaped frame 2. The groove 14 is adapted to the threaded rod 15. When the power cord 11 of the Bluetooth speaker is short, the threaded rod 15 can be unscrewed from the threaded groove 14, and then the U-shaped frame 2 can be pulled down. The U-shaped frame 2 will drive the rotating rod 3, the crossbar 7 and the mounting sleeve 6 to move down. When the U-shaped frame 2 moves to the appropriate position, the threaded rod 15 can be screwed into another threaded groove 14. At this time, the U-shaped frame 2 can be fixed near the power cord 11. When the power cord 11 is short, it can also be stored, expanding the range of use.

[0026] Reference Figure 1 and Figure 4 The top of the speaker body 1 is fixedly connected to a handle 16, and four casters 17 are installed at the bottom corners of the speaker body 1. Users can move the Bluetooth speaker by pulling the handle 16 to rotate the casters 17, which is more effortless and convenient and improves the portability of the Bluetooth speaker.

[0027] In this invention, the working principle is as follows: When the user does not need to use the Bluetooth speaker power cord 11, they pull open the elastic lever 4 by hand, place the power cord 11 near the plug 12 inside the elastic lever 4, and release their hand. The end of the power cord 11 near the plug 12 is held by the elastic lever 4. Then, they pull the lever 9 to move the mounting sleeve 6 and the crossbar 7 towards the speaker body 1. At this time, the mounting sleeve 6 will compress the spring 8. When the distance between the crossbar 7 and the rotating rod 3 is large enough, they turn the knob 10. The rotation of the knob 10 will cause the rotating rod 3, the elastic lever 4, and the plug 12 to rotate. The rotation of the plug 12 can wrap the power cord 11 around the outside of the rotating rod 3. When the power cord 11 between the rotating rod 3 and the speaker body 1 is taut, stop rotating the knob 10 and release the pull rod 9. At this time, under the action of the rebound potential energy of the spring 8, the mounting sleeve 6 will drive the crossbar 7 to move away from the speaker body 1. At this time, the crossbar 7 and the rotating rod 3 will clamp the power cord 11 wrapped around the outside of the rotating rod 3. At the same time, under the pressure of the crossbar 7, the power cord 11 generates a large friction force between the crossbar 7 and the rotating rod 3, which can prevent the rotating rod 3 from rotating at will, thereby fixing the power cord 11 to the outside of the rotating rod 3, storing the power cord 11, preventing pedestrians from tripping over the power cord 11, and also preventing the power cord 11 from being dragged on the ground and damaged. When the power cord 11 is relatively short, the threaded rod 15 can be unscrewed from the threaded groove 14, and then the U-shaped frame 2 can be pulled down. The U-shaped frame 2 will drive the rotating rod 3, the crossbar 7 and the mounting sleeve 6 to move down. When the U-shaped frame 2 moves to the appropriate position, the threaded rod 15 can be screwed into another threaded groove 14. At this time, the U-shaped frame 2 can be fixed near the power cord 11. The power cord 11 can be fixed to the outside of the rotating rod 3 using the same operation as above. When the power cord 11 is short, the user can also store it.
