Description

Technical Field

[0001] The utility model relates to the technical field of audio, in particular to a track-type movable and fixed audio device. Background Art

[0002] Audio refers to a device that uses electronic circuit design to convert audio and electronic signals. In general speaking, audio usually refers to a complete set of equipment that can restore and play audio signals. Audio equipment generally includes power amplifiers, peripheral equipment (including compressors, effects, equalizers, VCDs, DVDs, etc.), speakers (sound boxes, speakers), mixing consoles, etc.

[0003] In large concerts, the venue is large. In order to ensure that there is sound at different locations of the concert, a track is set up to drive the speakers to move. The speakers are connected to the track mobile platform through a fixing device. However, the existing connection and fixing devices are generally fastened by bolts, and the installation process is relatively cumbersome. To this end, we provide a track-type movable fixed speaker device to solve the above problems. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-5As shown, the utility model provides a technical solution: a track-type movable fixed sound device, comprising a supporting mainboard 1, a mounting platform 2 is arranged above the supporting mainboard 1, four vertical rods 3 are fixedly connected to the bottom surface of the mounting platform 2, the supporting mainboard 1 is slidably sleeved on the outer surface of the vertical rod 3, and the outer surface of each vertical rod 3 and the upper and lower sides of the supporting mainboard 1 are slidably sleeved with a balance spring 4, the two balance springs 4 on the outer surface of each vertical rod 3 are fixedly connected to the lower end of the vertical rod 3 and the bottom surface of the mounting platform 2 at one end away from each other, and the two balance springs 4 on each vertical rod 3 are fixedly connected to the upper and lower surfaces of the supporting mainboard 1 at one end close to each other. Two side bending plates 5 are fixedly connected to the upper surface of the mounting platform 2. Two longitudinal axes 6 are arranged between the two side bending plates 5 and above the mounting platform 2. Two through rods 9 are rotatably sleeved on the outer surface of each longitudinal axis 6. Two straight rods 7 are slidably penetrated through the right side surfaces of the two side bending plates 5. The four straight rods 7 are respectively fixedly connected to the four through rods 9. A clamping spring 8 is movably sleeved on the outer surface of each straight rod 7. The two ends of the clamping spring 8 are respectively fixedly connected to the adjacent side bending plates 5 and the through rod 9. A clamping side plate 11 is fixedly sleeved on the outer surface of each longitudinal axis 6. The clamping spring 8 has a tendency to push the two clamping side plates 11 closer to each other. The two clamping side plates 11 The sides close to each other are fixedly connected with anti-skid pads 13, and the lower ends of the sides away from each other of the two clamping side plates 11 are fixedly connected with stoppers 14. The anti-skid pads 13 increase the friction between the clamping side plates 11 and the speaker to prevent the speaker from being separated from the clamping side plates 11 when moving after the clamping side plates 11 clamp the speaker. The stoppers 14 limit the maximum distance between the upper ends of the two clamping side plates 11. After the speaker is placed above the two clamping side plates 11 in an "eight" shape, the two clamping side plates 11 can be pushed away from each other by applying downward pressure to the speaker. The two clamping side plates 11 are elastically connected to the back sides of the two through rods 9 located in the front, respectively. The front end of the longitudinal axis 6 is The bent structure has two front through rods 9 fixedly connected to the fixed angle plates 12 on their front sides, and the front ends of the two longitudinal axes 6 are located between the two fixed angle plates 12. When the clamping side plates 11 are rotated to a vertical state, the front ends of the longitudinal axes 6 are in contact with the fixed angle plates 12, so that the clamping side plates 11 can only be rotated to a vertical state to clamp the audio system. The front and back sides of the supporting mainboard 1 are fixedly connected to the track support frames 10, and the left and right ends and the middle position of the bottom surface of the track support frames 10 are rotatably connected to support rollers 19. The two track support frames 10 are symmetrically distributed front and back with the axis of the supporting mainboard 1, and the support rollers 19 improve the smoothness of the track support frames 10 when moving relative to the track.

[0025] The front and back sides of the support mainboard 1 are fixedly connected with groove card plates 15, the lower end of the through rod 9 slides through the upper surface of the mounting platform 2, the support mainboard 1 is located between the four through rods 9, and the left and right sides of the through rod 9 are rotatably connected with upper rollers 17, and the upper surface of the support mainboard 1 is provided with four transverse grooves 18, and the four through rods 9 are respectively slidably inserted in the inside of the four transverse grooves 18, and the width of the transverse groove 18 is smaller than the thickness of the upper roller 17. The upper roller 17 supports the through rod 9 to reduce the resistance of the through rod 9 when it moves. The lower end of the through rod 9 is fixedly connected with a card block 16 close to the side of the support mainboard 1, and the card block 16 is close to the side of the support mainboard 1 After engaging with the adjacent groove card plate 15 and placing the speaker above the two clamping side plates 11, a downward thrust is applied to the speaker to push the card block 16 to move to the bottom of the groove card plate 15 so that the through rod 9 can move. When the downward pressure on the speaker is stopped, the balance spring 4 pushes the mounting platform 2 to move upward, so that the card block 16 engages with the groove card plate 15 upward, and fixes the position of the clamping side plate 11 so that the clamping side plate 11 can stably clamp the speaker. When disassembling the speaker, lift the speaker upward, pull the mounting platform 2 and the card block 16 upward to disengage from the groove card plate 15, so that the speaker can be disengaged from between the two clamping side plates 11.

[0026] Working principle: Place the speaker between the two clamping side plates 11. The clamping side plates 11 are in an inverted eight shape under the action of the stop block 14, applying a downward thrust to the speaker, pushing the mounting platform 2 to move downward relative to the supporting main board 1, causing the balance spring 4 to deform and push the card block 16 to move below the groove card plate 15. The speaker pushes the two clamping side plates 11 away from each other to compress the clamping spring 8. When the clamping side plates 11 rotate to a vertical state, the clamping springs 8 on both sides of the two clamping side plates 11 quickly clamp the speaker between the two clamping side plates 11, and then stop applying pressure to the speaker. The balance spring 4 pushes the mounting platform 2 to move upward, causing the card block 16 to engage with the groove card plate 15 upward, limiting the left and right positions of the through rod 9, so that the clamping side plates 11 can stably clamp the speaker. When disassembling the speaker, lift the speaker upward, pull the mounting platform 2 and the card block 16 upward to disengage from the groove card plate 15, so that the speaker can be disengaged from between the two clamping side plates 11.
