Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, specifically to a highly stable loudspeaker that prevents loosening. Background Technology

[0002] The loudspeaker originally belonged to a type of wind instrument, but nowadays it mostly refers to an electroacoustic component, which is a loudspeaker that amplifies sound. It contains a vibration system, magnetic circuit system, support components, and signal converters, and can emit sound from a specific location. The openness or enclosure of the surrounding environment also affects the transmission of sound from the loudspeaker.

[0003] To maximize the effectiveness of electric loudspeakers, they are often fixed directly to a high point on a pole. Audio files are transmitted to a controller via radio signals, and sound is emitted after conversion. However, loudspeakers fixed at high altitudes are usually heavy, and without reinforcement, they are extremely easy to fall due to sound vibrations or wind during use.

[0004] Now, a new type of highly stable, anti-loosening speaker is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a highly stable speaker that prevents loosening, so as to solve the problem of poor stability mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a highly stable horn that prevents loosening, comprising a pole and a sleeve block. The top of the pole is fitted with the sleeve block, and a controller is fixed to the left side of the sleeve block. A horn cover is fixed to the left side of the controller. Suspension ropes are fixed to the front and rear of the top of the controller, respectively. A frame is fixed to the front and rear of the top of the pole, and a reel is movably connected between the front and rear of the frame. A lifting block is fixed to the top of the frame, and a bolt is threaded to the center of the lifting block. A crank is movably connected between the reel and the frame. A slot is provided on the left side of the top of the pole, and a groove is provided at the lower left corner of the frame.

[0007] As a further technical solution of this utility model, the top end of the hoisting rope is wound in the reel, and the crank can drive the reel to rotate.

[0008] As a further technical solution of this utility model, the suspension rope passes through the groove, and the bottom of the suspension rope is symmetrically fixed to the front and rear ends above the controller.

[0009] As a further technical solution of this utility model, a through groove is provided between the upper and lower parts inside the sleeve block, a right screw hole is provided at the center of the right side inside the sleeve block, a left screw hole is provided at the center of the left side inside the sleeve block, and a middle screw hole is provided between the two sides inside the top of the upright rod. Two bolts are threadedly connected between the right screw hole, the left screw hole and the middle screw hole.

[0010] As a further technical solution of this utility model, the external thread of the second bolt matches the inner wall of the right threaded hole, the left threaded hole and the middle threaded hole, and the second bolt is arranged in concentric circles with the right threaded hole, the left threaded hole and the middle threaded hole.

[0011] As a further technical solution of this utility model, the sleeve block and the upright are on the same vertical plane, and the sleeve block slides up and down along the surface of the upright.

[0012] As a further technical solution of this utility model, a cylinder is fixed to the top right side of the upright, and a piston rod is horizontally installed in the cylinder. A fixing block is installed on the left side of the piston rod, and a motor is installed in the fixing block. A rotating rod is movably connected to the left side of the fixing block, and a vertical plate is welded to the bottom of the rotating rod. A protective shell is fixed to the right side of the vertical plate, and a support plate is fixed to the left side of the top of the controller.

[0013] As a further technical solution of this utility model, the piston rod horizontally enters and exits the groove above the support plate, and the left side of the output end of the motor is fixedly connected to the rotating rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the anti-loosening high stability speaker not only maintains the stability of the speaker body and facilitates installation and disassembly, but also protects the speaker.

[0015] (1) By fixing the frame at the front and rear of the top of the pole respectively, when installing the horn device, hold the cranks installed on the surface of the two sets of frames respectively, and force the reel inside the frame to wind up the hoisting rope, thereby passing through the slot and the slotted to tighten the hoisting rope. Tighten the bolts connected in the threaded holes on the surface of the frame to reinforce it. The horizontally installed controller and horn cover can be suspended from the front and rear sides, improving the stability of the horn after installation.

[0016] (2) By attaching a sleeve block to the top of the pole, the sleeve block with a through groove moves upward along the surface of the pole. When the sleeve block rises to the top, the right screw hole and left screw hole inside the sleeve block are aligned with the middle screw hole in the pole. Then, the bolt is screwed in horizontally to fix it. By the snapping between the threads and screw holes, the friction force can be increased, making it easy to install and disassemble the speaker body. It will not easily loosen or slip.

[0017] (3) By fixing a protective shell on the right side of the vertical plate, when the horn is idle, start the cylinder and pull the piston rod horizontally through the hole at the top of the support plate, so that the vertical plate and the protective shell move to the right and cover the left side of the horn cover for rain and dust protection. If the horn is to be used, push the piston rod, fixing block, rotating rod, vertical plate and protective shell to the left, then start the motor and rotate the vertical plate and protective shell backward. This does not affect the controller's normal operation of the horn cover. 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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4An embodiment of this utility model provides a highly stable horn that is resistant to loosening, comprising a pole 1 and a sleeve block 2. The top of the pole 1 is sleeved with the sleeve block 2, and a controller 3 is fixed to the left side of the sleeve block 2. A horn cover 4 is fixed to the left side of the controller 3. A suspension rope 16 is fixed to the front and rear of the top of the controller 3. A frame 12 is fixed to the front and rear of the top of the pole 1, and a reel 13 is movably connected between the front and rear of the frame 12. A suspension block 17 is fixed to the top of the frame 12, and a bolt 18 is threadedly connected to the center of the suspension block 17. A crank 14 is movably connected between the reel 13 and the frame 12. A slot 19 is provided on the left side of the top of the pole 1, and a slot 20 is provided at the lower left corner of the frame 12.

[0025] The top of the suspension rope 16 is wound in the reel 13, and the crank 14 can drive the reel 13 to rotate. The suspension rope 16 passes through the slot 20, and the bottom of the suspension rope 16 is symmetrically fixed to the front and rear ends above the controller 3.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, when installing the horn device, hold the crank handles 14 installed on the surface of the two sets of frames 12 respectively, forcing the reel 13 inside the frame 12 to wind up the hanging rope 16, thereby passing through the slot 20 and the slot 19 to tighten the hanging rope 16. Tighten the bolts 18 threaded in the holes on the surface of the frame 12 for reinforcement, so that the horizontally installed controller 3 and horn cover 4 can be suspended from the front and rear sides.

[0027] A through groove 21 is provided between the upper and lower parts inside the sleeve 2. A right screw hole 22 is provided at the center of the right side inside the sleeve 2. A left screw hole 24 is provided at the center of the left side inside the sleeve 2. A middle screw hole 23 is provided between the two sides inside the top of the upright 1. A bolt 25 is threadedly connected between the right screw hole 22, the left screw hole 24 and the middle screw hole 23.

[0028] The external thread of bolt 25 matches the inner wall of the right screw hole 22, the left screw hole 24 and the middle screw hole 23. Bolt 25 is arranged in concentric circles with the right screw hole 22, the left screw hole 24 and the middle screw hole 23. Sleeve 2 and upright 1 are on the same vertical plane. Sleeve 2 slides up and down along the surface of upright 1.

[0029] Specifically, such as Figure 1 and Figure 3 As shown, the sleeve block 2 with through groove 21 moves upward along the surface of the upright 1. When the sleeve block 2 rises to the top, the right screw hole 22 and the left screw hole 24 inside the sleeve block 2 are aligned with the middle screw hole 23 in the upright 1. Then, the bolt 25 is screwed in horizontally to fix it. The interlocking between the threads and screw holes can increase the friction force, making it convenient to install and disassemble the speaker body.

[0030] A cylinder 15 is fixed to the top right side of the upright 1, and a piston rod 10 is horizontally installed in the cylinder 15. A fixing block 8 is installed on the left side of the piston rod 10, and a motor 9 is installed in the fixing block 8. A rotating rod 7 is movably connected to the left side of the fixing block 8, and a vertical plate 6 is welded to the bottom of the rotating rod 7. A protective shell 5 is fixed to the right side of the vertical plate 6. A support plate 11 is fixed to the left side of the top of the controller 3. The piston rod 10 moves horizontally into and out of the groove above the support plate 11. The left side of the output end of the motor 9 is fixedly connected to the rotating rod 7.

[0031] Specifically, such as Figure 1 and Figure 4 As shown, when the horn is not in use, the cylinder 15 is activated, and the piston rod 10 is horizontally pulled through the hole at the top of the support plate 11, so that the vertical plate 6 and the protective shell 5 move to the right and cover the left side of the horn cover 4 for rain and dust protection. If the horn is to be used, the piston rod 10, the fixing block 8, the rotating rod 7, the vertical plate 6 and the protective shell 5 are pushed to the left, and then the motor 9 is activated and the vertical plate 6 and the protective shell 5 are rotated backward.

[0032] Working principle: In use, the sleeve block 2 with the through groove 21 is first moved upward along the surface of the upright 1. When the sleeve block 2 reaches the top, the right screw hole 22 and the left screw hole 24 inside the sleeve block 2 align with the middle screw hole 23 inside the upright 1. Then, the bolt 25 is screwed in horizontally for fixation. The friction is increased by the interlocking between the threads and screw holes. Then, the crank handles 14 installed on the surface of the two sets of frame bodies 12 are held respectively, forcing the reel 13 inside the frame body 12 to wind up the suspension rope 16, thereby passing through the groove 20 and the slot 19 to tighten the suspension rope 16. The bolts 18, threaded in the holes on the surface of the frame 12, are used to reinforce the horizontally installed controller 3 and horn cover 4. When the horn is not in use, the cylinder 15 is activated, and the piston rod 10 is pulled horizontally through the hole at the top of the support plate 11, so that the vertical plate 6 and the protective shell 5 move to the right and cover the left side of the horn cover 4 for rain and dust protection. When the horn is to be used, the piston rod 10, the fixing block 8, the rotating rod 7, the vertical plate 6 and the protective shell 5 are pushed to the left, and then the motor 9 is activated and the vertical plate 6 and the protective shell 5 are rotated backward to expose the horn cover 4 and make it sound.
