Description

Technical Field

[0001] This invention relates to the field of horn fixing, and more particularly to a horn fixing device. Background Technology

[0002] To better inform people or broadcast announcements, loudspeakers are installed in many places, such as rural areas, towns, and schools. However, loudspeakers pose a risk of falling from heights, so the stability of loudspeakers has always been a key consideration during installation.

[0003] Generally, when fixing a loudspeaker, workers first use screws and nuts to secure the iron frame to the utility pole, and then use screws and nuts to fix the loudspeaker to the iron frame. After a long period of exposure to wind and rain, the screws, nuts, and iron frame will rust or loosen. When the loudspeaker needs to be reinforced again, since the screws, nuts, and iron frame do not have the reinforcement capacity, workers need to first remove the rusted or loose screws, nuts, and iron frame, and then replace them with new screws, nuts, and iron frames to reinforce the loudspeaker, resulting in low overall work efficiency.

[0004] Therefore, there is an urgent need to develop a horn fixing device with reinforcement capabilities. Summary of the Invention

[0005] To overcome the shortcomings of insufficient reinforcement capabilities of horns, the technical problem is to provide a horn fixing device with reinforcement capabilities.

[0006] The technical solution is as follows: A horn fixing device includes a fixing frame, a horn, a limiting rod, a clamping mechanism, and a friction enhancing mechanism. The fixing frame is installed in the middle of the fixing column, the horn is installed in the front of the fixing frame, the limiting rods are installed on both the left and right sides of the fixing frame, and the clamping mechanism is slidably installed on the limiting rods. The clamping mechanism is used to clamp the horn, and the friction enhancing mechanism is installed on the upper part of the clamping mechanism. The friction enhancing mechanism enhances the friction of the fixing column to achieve a fixing effect.

[0007] Preferably, the clamping mechanism includes a first support frame, a rotating wheel, a threaded rod, a clamping block, a slider, and a first sliding rod. The first support frame is slidably installed between the two limiting rods. Threaded rods are threadedly installed on both the left and right sides of the first support frame. A rotating wheel is installed on the outer side of each of the two threaded rods. The first sliding rods are installed on both the left and right sides of the upper inner wall of the first support frame. A slider is slidably installed on the outer side of each of the two first sliding rods. A clamping block is installed at the lower part of each of the two sliders. The clamping block and the threaded rod are rotatably connected.

[0008] Preferably, the friction enhancement mechanism includes a second support frame, a movable claw, a first compression spring, a first locking block, a first telescopic spring, a second slide rod, and a third slide rod. Second support frames are installed on the upper left and right sides of the rear of the first support frame. Each of the two second support frames has a groove at its rear. A second slide rod is installed between the inner walls of the grooves on the left and right sides of each second support frame. A movable claw is slidably installed on each of the two second slide rods. A first compression spring is wound around each of the two second slide rods, and the first compression spring is connected to the inner wall of the groove on the second support frame and the lower part of the movable claw, respectively.

A first telescopic spring is wound around each of the two third slide rods, and the two ends of the first telescopic spring are connected to the lower rear side of the first locking block and the inner rear wall of the second support frame, respectively.

[0009] Preferably, a tightening mechanism is also included. The tightening mechanism is installed at the rear of the first support frame. The tightening mechanism tightens and protects the horn connection, thereby strengthening the fixation of the horn connection. The tightening mechanism includes a pressure rod, an air cylinder, a pressure spring, an air guide tube, a fixing rod, and an inflatable air bladder. Pressure rods are installed at the rear of both clamping blocks. Fixing rods are symmetrically installed on the left and right sides of the upper rear of the first support frame. Air cylinders are installed at the lower part of both fixing rods. The outer sides of both air cylinders are slidably connected to the pressure rods that are close to each other. A pressure spring is wound around the rear of the pressure rod. The two ends of the pressure spring are connected to the air cylinder and the pressure rod, respectively. An air guide tube is connected to the inner side of both air cylinders. An inflatable air bladder is connected to the inner side of both air guide tubes. The inflatable air bladder is embedded in the lower inner side of the fixing rod.

[0010] Preferably, a reinforcing mechanism is also included. A reinforcing mechanism is installed in the middle of the rear of the first support frame. The reinforcing mechanism can increase the friction of the friction enhancement mechanism, thereby strengthening the fixation of the horn fixing device. The reinforcing mechanism includes an elastic pull rope, a guide frame, a pressing block, a telescopic rod, and a second telescopic spring. A guide frame is installed in the middle of the rear of the first support frame. A telescopic rod is installed in the middle of the guide frame. A pressing block is slidably installed at the rear of the guide frame. The rear of the telescopic rod is connected to the front of the pressing block. A second telescopic spring is wound around the rear of the telescopic rod. The two ends of the second telescopic spring are respectively connected to the rear of the telescopic rod and the front of the pressing block. Elastic pull ropes are connected to the moving claws on the same side on both sides of the inner wall of the front of the pressing block. The two elastic pull ropes are respectively wound around the left and right sides of the rear of the guide frame.

[0011] Preferably, a shielding mechanism is also included. The shielding mechanism is installed on the upper part of the first support frame. The shielding mechanism is used to shield the speaker fixing device from rainwater. The shielding mechanism includes a baffle, a rotating shaft, and a second locking block. A rotating shaft is installed in the middle of the upper part of the first support frame. Baffles are rotatably installed on both sides of the rotating shaft. The two baffles are placed on the left and right sides of the upper part of the first support frame, respectively. A second locking block is installed on the right side of the left baffle. A groove is opened on the left side of the right baffle. The second locking block is made of fluffy sponge block and is used to lock into the groove of the right baffle to increase friction and prevent the two baffles from easily separating.

[0012] Preferably, a portable mechanism is also included. A portable mechanism is installed on the upper left and upper right sides of the first support frame. The portable mechanism is used to prevent the staff from accidentally dropping the speaker fixing device and causing safety hazards. The portable mechanism includes a handle, a bonding block, and a second compression spring. A handle is installed on the upper left and upper right sides of the first support frame. A bonding block is slidably installed in each of the two handles. A second compression spring is installed on the upper and lower sides of each of the two bonding blocks. The second compression spring is connected to the outer side of the first support frame and the inner wall of the bonding block, respectively.

[0013] Preferably, the extrusion block is made of rubber, and the rubber block has strong friction when in contact with the surface of the fixed column.

[0014] The beneficial effects of the present invention are: 1. The present invention installs the horn fixing device by limiting rods on the left and right sides, and then rotates the rotating wheel to drive the threaded rods on the left and right sides to move inward, so that the clamping blocks on the left and right sides move inward, thereby achieving the effect of clamping the horn.

[0015] 2. In this invention, by pushing the two first locking blocks backward, the first compression springs on the left and right sides are reset, which drives the moving claws on the left and right sides to move inward respectively. The moving claws on the left and right sides will contact the fixed column, and the fixed effect is achieved by increasing the friction between the moving claws and the fixed column.

[0016] 3. This invention rotates the rotating wheel, causing the clamping blocks on the left and right sides to move inward under the action of the slider, thereby causing the pressure rods on the left and right sides to move inward. Then, the air cylinders on the left and right sides inflate the expansion airbag, causing the expansion airbag to expand, thereby achieving the effect of wrapping and protecting the horn connection and strengthening the fixation of the horn connection.

[0017] 4. By pushing the two first locking blocks backward, the moving claws on the left and right sides move inward respectively. Then, the elastic ropes on the left and right sides move the squeezing block backward. The second telescopic spring deforms, and the squeezing block contacts the fixed column, thereby increasing the friction of the friction enhancement mechanism and strengthening the fixation of the horn fixing device.

[0018] 5. This invention pushes the left and right side baffles outward to check the position of the limiting rod, which facilitates the precise installation of the entire fixing device. After installation, the left and right side baffles are pushed inward to merge the left and right side baffles, thereby achieving the function of shielding and protecting the speaker.

[0019] 6. The present invention compresses the second compression spring by squeezing the adhesive block inside the handle. Under the elastic force of the second compression spring, the adhesive block will fit more tightly with the hand, thus preventing the worker from accidentally slipping out of their hand and causing safety hazards when disassembling or assembling the speaker fixing device.

Detailed Implementation

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] Example 1

[0038] A horn fixing device, such as Figures 1-7 As shown, it includes a fixing frame 2, a horn 3, a limiting rod 4, a clamping mechanism 5, and a friction enhancing mechanism 6. The fixing frame 2 is welded to the middle of the fixing column 1, the horn 3 is installed at the front of the fixing frame 2, and the limiting rods 4 are connected to both the left and right sides of the fixing frame 2. The clamping mechanism 5 is slidably installed on the limiting rod 4. The clamping mechanism 5 is used to clamp the horn 3. The friction enhancing mechanism 6 is installed on the upper part of the clamping mechanism 5. The friction enhancing mechanism 6 enhances the friction of the fixing column 1 to achieve a fixing effect.

[0039] like Figure 4 and Figure 5As shown, the clamping mechanism 5 includes a first support frame 51, a rotating wheel 52, a threaded rod 53, a clamping block 54, a slider 55, and a first sliding rod 56. The first support frame 51 is slidably connected between the two limiting rods 4. The first support frame 51 is used to support the entire clamping mechanism. The left and right sides of the first support frame 51 are threadedly connected to the threaded rod 53. The rotating wheel 52 is fixedly connected to the outer side of the two threaded rods 53. By rotating the rotating wheel 52, the threaded rod 53 is driven to move inward. The left and right sides of the upper inner wall of the first support frame 51 are connected to the first sliding rod 56. The slider 55 is slidably connected to the outer side of the two first sliding rods 56. The clamping block 54 is fixedly connected to the lower part of the two sliders 55. The clamping block 54 is used to clamp the horn 3. The clamping block 54 and the threaded rod 53 are rotatably connected.

[0040] like Figure 6 and Figure 7 As shown, the friction enhancement mechanism 6 includes a second support frame 61, a movable claw 62, a first compression spring 63, a first locking block 64, a first telescopic spring 65, a second slide rod 66, and a third slide rod 67. The second support frame 61 is fixedly connected to both the left and right sides of the upper rear part of the first support frame 51. The second support frame 61 supports the entire friction enhancement mechanism 6. Each of the two second support frames 61 has a groove at its rear. The inner walls of the grooves on both sides of the second support frame 61 are fixedly connected to the second slide rod 66. Movable claws 62 are slidably mounted on both second slide rods 66. The movable claw 62 is used to enhance friction. A first compression spring 63 is wound around each of the two second slide rods 66. The first compression spring 63 is connected to the inner wall of the groove on the second support frame 61 and the lower part of the movable claw 62, respectively. A third slide rod 67 is fixedly connected to the rear of each of the two second support frames 61. A first locking block 64 is slidably installed on each of the third slide rods 67. The first locking block 64 is used to lock the movable claw 62. A first telescopic spring 65 is wound around each of the two third slide rods 67. The two ends of the first telescopic spring 65 are connected to the lower rear side of the first locking block 64 and the inner rear side of the second support frame 61, respectively.

[0041] In the initial state of the friction enhancement mechanism 6, the movable claw 62 is held by the first locking block 64, and the first compression spring 63 is compressed. After the operator installs the speaker fixing device by first using the limiting rods 4 on both sides, the first locking blocks 64 on both sides are pushed backward, the first telescopic springs 65 on both sides are compressed, and the first compression springs 63 on both sides return to their original positions, causing the movable claws 62 on both sides to slide inward respectively. The movable claws 62 on both sides will contact the fixing post 1, enhancing the friction against the fixing post 1. When the movable claws 62 on both sides stop sliding, the first locking block 64 is released, the first telescopic springs 65 on both sides return to their original positions, and the first locking blocks 64 on both sides are released. 64 slides forward, locking the moving claws 62 on both sides, preventing them from sliding outward. In order to clamp the horn 3, the operator rotates the rotating wheels 52 on both sides, causing the threaded rods 53 on both sides to move inward, causing the clamping blocks 54 on both sides to move inward, thereby causing the sliders 55 on both sides to slide inward. When the clamping blocks 54 on both sides move to contact the horn 3 and can no longer move inward, the rotation of the rotating wheels 52 on both sides is stopped. When the rotating wheels 52 on both sides move the threaded rods 53 on both sides outward, they cause the clamping blocks 54 on both sides to move outward, thereby causing the sliders 55 on both sides to slide outward.

[0042] Example 2

[0043] Based on Example 1, such as Figure 8 and Figure 9 As shown, it also includes a wrapping mechanism 7. The wrapping mechanism 7 is installed at the rear of the first support frame 51. The wrapping mechanism 7 wraps and protects the connection of the horn 3, thereby strengthening the fixation of the connection of the horn 3. The wrapping mechanism 7 includes a pressure rod 71, an air cylinder 72, a pressure spring 73, an air guide tube 74, a fixing rod 75, and an inflatable air bag 76. The pressure rod 71 is fixedly connected to the rear of both clamping blocks 54. The fixing rods 75 are symmetrically fixedly connected to the left and right sides of the upper rear side of the first support frame 51. Each fixed rod 75 has an air cylinder 72 fixedly connected to its lower part. The air cylinder 72 is used to inflate the airbag 76. The outer sides of both air cylinders 72 are slidably connected to the adjacent pressure rod 71. A pressure spring 73 is wound around the rear of the pressure rod 71. The two ends of the pressure spring 73 are connected to the air cylinder 72 and the pressure rod 71 respectively. The inner sides of both air cylinders 72 are connected to air guide tubes 74. The inner sides of both air guide tubes 74 are connected to the airbag 76. The airbag 76 is embedded in the lower inner side of the fixed rod 75.

[0044] To tighten and protect the connection of the horn 3, thus strengthening its stability, when the clamping blocks 54 on both sides move inward, they drive the pressure rods 71 ​​on both sides to move inward. The pressure rods 71 ​​on both sides compress the air cylinders 72 on the same side, compressing the pressure springs 73 on both sides. Then, the gas in the air cylinders 72 on both sides enters the inflatable airbags 76 through the air guide tubes 74, causing the inflatable airbags 76 on both sides to inflate and tighten the connection of the horn 3. When the clamping blocks 54 on both sides move outward, they drive the pressure rods 71 ​​on both sides to move outward. The pressure springs 73 on both sides return to their original position, causing the air cylinders 72 on both sides to slide outward. Through the air guide tubes 74, air is drawn into the inflatable airbags 76 on both sides, causing them to contract.

[0045] like Figure 10 and Figure 11 As shown, it also includes a reinforcing mechanism 8. The reinforcing mechanism 8 is installed in the middle of the rear of the first support frame 51. The reinforcing mechanism 8 can increase the friction of the friction enhancement mechanism 6, thereby strengthening the fixation of this horn fixing device. The reinforcing mechanism 8 includes an elastic pull rope 81, a guide frame 82, a compression block 83, a telescopic rod 84, and a second telescopic spring 85. The guide frame 82 is fixedly connected to the middle of the rear of the first support frame 51. The telescopic rod 84 is fixedly connected to the middle of the guide frame 82. The compression block 84 is slidably installed at the rear of the guide frame 82. The pressure block 83 is made of rubber. The rubber block has strong friction when in contact with the surface of the fixed column 1. The front part of the pressure block 83 is connected to the rear part of the telescopic rod 84. The rear part of the telescopic rod 84 is wrapped with a second telescopic spring 85. The two ends of the second telescopic spring 85 are respectively connected to the rear part of the telescopic rod 84 and the front part of the pressure block 83. The left and right sides of the inner wall of the front part of the pressure block 83 are connected to the moving claw 62 on the same side. The two elastic pull ropes 81 are respectively wrapped around the left and right sides of the rear part of the guide frame 82.

[0046] To increase the friction of the friction enhancement mechanism 6 and strengthen the fixation of the horn fixing device, when the moving claws 62 on both sides move inward, the compression block 83 will move backward through the taut elastic ropes 81 on both sides. The second telescopic spring 85 will be stretched, the telescopic rod 84 will extend, and the compression block 83 will contact the fixing post 1, increasing the friction and strengthening the fixation of the horn fixing device. When the moving claws 62 on both sides move outward, the elastic ropes 81 will be relaxed, the second telescopic spring 85 will return to its original position, and the compression block 83 will move forward.

[0047] like Figure 12 and Figure 13As shown, it also includes a shielding mechanism 9. The shielding mechanism 9 is installed on the upper part of the first support frame 51. The shielding mechanism 9 is used to shield the speaker fixing device from rainwater. The shielding mechanism 9 includes a baffle 91, a rotating shaft 92, and a second locking block 93. The rotating shaft 92 is fixedly connected to the middle of the upper part of the first support frame 51. The baffle 91 is rotatably installed on the left and right sides of the rotating shaft 92. The two baffles 91 are located on the left and right sides of the upper part of the first support frame 51, respectively. The right side of the left baffle 91 is fixedly connected to the second locking block 93. The left side of the right baffle 91 has a groove. The second locking block 93 is made of fluffy sponge and is used to lock into the groove of the right baffle 91 to increase friction and prevent the two baffles 91 from easily separating.

[0048] When preparing to install the speaker fixing device on the speaker 3, the staff will push the baffles 91 on both sides outwards to check the position of the limit rod 4, so as to accurately install the entire speaker 3 fixing device. After installation, push the baffles 91 on both sides inwards to merge the baffles 91 on both sides, so as to achieve the function of shielding and protecting the speaker 3.

[0049] like Figure 14 and Figure 15 As shown, it also includes a portable mechanism 10. The portable mechanism 10 is installed on the upper left and upper right sides of the first support frame 51. The portable mechanism 10 is used to prevent the staff from accidentally dropping the speaker fixing device when disassembling and assembling it, which may cause safety hazards. The portable mechanism 10 includes a handle 101, a bonding block 102 and a second compression spring 103. The handle 101 is welded to the upper left and upper right sides of the first support frame 51. The handle 101 makes it easy for the staff to lift the speaker fixing device. The bonding block 102 is slidably installed in both handles 101. The second compression spring 103 is installed on the upper and lower sides of both bonding blocks 102. The second compression spring 103 is connected to the outer side of the first support frame 51 and the inner wall of the bonding block 102, respectively.

[0050] When preparing to disassemble or install this speaker fixing device, the operator needs to hold the handles 101 on both sides. The fitting block 102 inside the handle 101 is squeezed, and the second compression spring 103 is compressed. During this process, under the elastic force of the second compression spring 103, the fitting block 102 will fit more tightly with the hand, and the operator will not accidentally slip out of their hand.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
