Description

Technical Field

[0001] The utility model relates to the technical field of digital audio processors, and specifically relates to a digital audio processor. Background Art

[0002] An audio processor is an electronic device or software used to process audio signals. It can perform various operations and processes on audio signals to improve sound quality, enhance sound effects, or achieve specific audio processing goals.

[0003] Existing published patent: CN202322240852.5, a digital audio processor, by providing two brackets, enables the audio processor to unfold the support frame and use it as two support feet during use. When multiple devices are stacked, the top frame and the support frame can isolate the upper device from the lower device, leaving a heat dissipation space to prevent the two devices from having poor heat dissipation or even heat accumulation due to close contact.

[0004] However, in this comparative example, only the support frame is rotatably connected inside the groove, and the top frame is fixedly connected to the support frame. The top frame and the support frame are used as a support structure to stack the devices. However, there is no limiting mechanism for the support frame and the top frame during use, allowing the support frame and the top frame to still rotate after stacking the devices. This makes it easy for the support frame to rotate inside the groove when the body shakes, resulting in the stacked devices tipping over, and thus the stability of the top frame is weak, reducing the safety of the digital audio processor.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0053] Please refer to Figures 1-6, the present utility model provides a new technical solution: a digital audio processor, including a body 1, the body 1 includes a socket, a ventilation opening, a dust-proof grille, screws, a cooling fan, studs, screw grooves, etc. The body 1 is the prior art in a digital audio processor of the existing publicly disclosed patent: CN202322240852.5, which will not be elaborated herein;

[0054] Among them, two connecting grooves 2 are opened on the upper surface of the body 1;

[0055] Among them, two fixing shafts 3 are rotatably connected between the front and rear inner walls of the two connecting grooves 2;

[0056] Among them, two first fixing blocks 5 are fixedly sleeved on the outer surface of the fixing shaft 3;

[0057] Among them, the structures on the two fixing shafts 3 are the same and are arranged in a mirror image;

[0058] Among them, positioning mechanisms are arranged on the two fixing shafts 3, and the two groups of positioning mechanisms are arranged in a mirror image.

[0063] Further, four rubber friction blocks 7 are fixedly connected to the outer surface of the four second fixing blocks 6 away from the first fixing block 5;

[0064] Among them, the four rubber friction blocks 7 are in a semi-cylindrical shape;

[0065] Among them, two rotating grooves 8 are opened on the body 1, and the two rotating grooves 8 communicate with the inside of the two connecting grooves 2;

[0066] Among them, two sector gears 9 are fixedly sleeved on the outer surface of the two fixing shafts 3.

[0067] Further, two fixing grooves 10 are opened inside the body 1, and the rotating groove 8 communicates with the inside of the fixing groove 10;

[0068] Wherein, the lower surfaces of the two racks 11 are slidably connected to the bottom walls of the two fixed grooves 10;

[0069] Wherein, the racks 11 are located within the fixed grooves 10;

[0070] Wherein, the sector gears 9 extend into the fixed grooves 10 through the rotation grooves 8 and are meshed with the racks 11;

[0071] Wherein, the two connecting blocks 19 are fixedly connected to the outer surfaces of the adjacent sides of the two racks 11.

[0072] Furthermore, the two connecting blocks 19 are slidably sleeved within the two fixed grooves 10;

[0073] Wherein, the four second tension springs 20 are fixedly connected to the outer surfaces of the adjacent sides of the two connecting blocks 19;

[0074] Wherein, the ends of the second tension springs 20 away from the connecting blocks 19 are fixedly connected to the inner walls of the fixed grooves 10;

[0075] Wherein, the two second sliding grooves 14 are formed on the upper surface of the body 1;

[0076] Wherein, the two positioning grooves 12 are formed on the outer surfaces of the two sector gears 9;

[0077] Wherein, the two first sliding grooves 13 are formed on the body 1;

[0078] Wherein, the first sliding grooves 13 communicate with the second sliding grooves 14 internally, and the two first sliding grooves 13 communicate with the two rotation grooves 8 internally.

[0079] Furthermore, the two second sliding blocks 16 are connected within the two first sliding grooves 13;

[0080] Wherein, the outer surfaces of the opposite sides of the two second sliding blocks 16 slidably extend into the two positioning grooves 12;

[0081] Wherein, the two first sliding blocks 15 are fixedly connected to the upper surfaces of the two second sliding blocks 16;

[0082] Wherein, the two first sliding blocks 15 are slidably connected to the two second sliding grooves 14;

[0083] Wherein, the two pushing plates 18 are fixedly connected to the upper surfaces of the two first sliding blocks 15, and the lower surfaces of the pushing plates 18 are slidably connected to the upper surface of the body 1;

[0084] Wherein, the four first springs 17 are fixedly connected to the inner walls of the adjacent sides of the two first sliding grooves 13;

[0085] Among them, the four first springs 17 are fixedly connected to the two second sliding blocks 16.

[0086] Furthermore, in this solution, in the initial state, the first fixing blocks 5 on the left and right sides are in a state of being opened away from each other, and the first fixing blocks 5 are opened in an inclined state away from each other. At this time, the positioning groove 12 does not contact the second sliding block 16, and at this time, the second tension spring 20 is in a state of not being stressed.

[0087] At this time, the first fixing block 5, the second fixing block 6, and the rubber friction block 7 can be turned downward so that the body 1 is inverted. Then the rubber friction block 7 contacts the tabletop, and then the body 1 is lifted, so that the space between the tabletop and the body 1 can be increased for heat dissipation, reducing heat accumulation. Also, the first fixing block 5, the second fixing block 6, and the rubber friction block 7 can be turned upward. Then the upper side of the rubber friction block 7 can support and isolate the equipment above. Thus, the first fixing block 5, the second fixing block 6, and the rubber friction block 7 play a role in accelerating heat dissipation and avoiding heat accumulation, thereby increasing the practicality of the digital audio processor and improving the heat dissipation effect of the digital audio processor.

[0088] As described above, in this solution, the elastic force of the second tension spring 20 is relatively strong, so that the first fixing block 5, the second fixing block 6, and the rubber friction block 7 have sufficient supporting force. The second tension spring prevents the sector gear 9 from rotating when the body 1 shakes or the like. Then the second tension spring 20 ensures that the rack 11 will not be easily driven to move left and right. Thus, it is ensured that in the initial state, there is sufficient supporting force for the equipment above or itself, and thus the first fixing block 5, the second fixing block 6, and the rubber friction block 7 are prevented from tipping over, ensuring the stability of the body 1, and thereby increasing the safety and practicality of the body 1.

[0089] As described above, when it is necessary to store the first fixing block 5, the second fixing block 6 and the rubber friction block 7 to reduce the space, it is necessary to first push the push plate 18 so that the push plate 18 moves away from the sector gear 9, thereby driving the first sliding block 15 and the second sliding block 16 to move synchronously, and then driving the second sliding block 16 to not contact the sector gear 9. At this time, the first spring 17 is also squeezed so that the first spring 17 is squeezed and deformed. And then push the first fixing block 5 at this time, so that the first fixing block 5, the second fixing block 6 and the rubber friction block 7 rotate around the fixed shaft 3. During this process, the sector gear 9 is synchronously driven to rotate, and then the rack 11 is synchronously driven to move. During the movement of the rack 11, the second tension spring 20 is stretched, so that the second tension spring 20 is stretched and deformed. When the first fixing block 5, the second fixing block 6 and the rubber friction block 7 rotate around the fixed shaft 3 to the horizontal state, the second sliding block 16 is at the same level as the positioning groove 12. At this time, release the push on the push plate 18. Under the action of the released elastic force of the first spring 17, drive the second sliding block 16 to slide into the positioning groove 12, thereby fixing the sector gear 9, so that the sector gear 9 cannot rotate. This also fixes the first fixing block 5, the second fixing block 6 and the rubber friction block 7, so that the first fixing block 5, the second fixing block 6 and the rubber friction block 7 are in a horizontal state. And when the first fixing block 5, the second fixing block 6 and the rubber friction block 7 are in a horizontal state, they are located in the connecting groove and the support groove 4, thereby storing the first fixing block 5, the second fixing block 6 and the rubber friction block 7, reducing the occupied space of the first fixing block 5, the second fixing block 6 and the rubber friction block 7, and further reducing the occupied space of the digital audio processor, thereby facilitating the carrying and transportation of the digital audio processor, and further increasing the practicability of the digital audio processor.

[0090] Furthermore, the rubber friction block 7 is made of rubber material. While the rubber friction block 7 plays a role in increasing the friction force, it further ensures the stability of the machine body 1 and thus the practicability of the digital audio processor.

[0091] Working principle: When the device is in use, in the initial state, the first fixing blocks 5 on the left and right sides are in a state of being opened away from each other. The first fixing blocks 5 are opened in an inclined state away from each other. At this time, the positioning groove 12 does not contact the second sliding block 16, and at this time the second tension spring 20 is in a state of not being stressed;

[0092] At this time, the first fixing block 5, the second fixing block 6 and the rubber friction block 7 can be turned downward so that the body 1 is inverted. Then the rubber friction block 7 contacts the tabletop, and the body 1 is lifted, so that the space between the tabletop and the body 1 can be increased for heat dissipation, reducing heat accumulation. Also, the first fixing block 5, the second fixing block 6 and the rubber friction block 7 can be turned upward. Then the upper side of the rubber friction block 7 can support and isolate the equipment above. Thus, the first fixing block 5, the second fixing block 6 and the rubber friction block 7 play a role in accelerating heat dissipation and avoiding heat accumulation, thereby increasing the practicability of the digital audio processor and improving the heat dissipation effect of the digital audio processor.

[0093] As described above, in this solution, the elastic force of the second tension spring 20 is relatively strong, so that the first fixing block 5, the second fixing block 6 and the rubber friction block 7 have sufficient supporting force. The second tension spring prevents the sector gear 9 from rotating when the body 1 shakes or the like. Thus, the second tension spring 20 ensures that the rack 11 will not be easily driven to move left and right, and ensures that there is sufficient supporting force for the equipment above or itself in the initial state, thereby preventing the first fixing block 5, the second fixing block 6 and the rubber friction block 7 from tipping over, ensuring the stability of the body 1, and increasing the safety and practicability of the body 1.
