Technical Field

[0001] This utility model relates to the field of musical instrument rack technology, specifically an adjustable rack for a loudspeaker. Background Technology

[0002] Musical instruments are instruments that can produce sounds and tones in various ways. They are generally divided into traditional Chinese instruments and Western instruments. They are tools capable of producing musical sounds and enabling the re-creation of musical art. Humans use musical instruments to express and communicate thoughts and feelings. There are many types of musical instruments, including the piano, guzheng, violin, triangle, and trumpet.

[0003] For example, Chinese patent CN211237707U, "Musical Instrument Storage Rack," features a driven gear fixedly mounted on the left end of a first winding shaft and a master gear fixedly mounted on the left end of a second winding shaft, with the master gear meshing with the driven gear. Both the first and second winding shafts have winding wheels fixedly mounted on their outer ends. Each winding wheel is covered with a dustproof curtain, one end of which is fixedly attached to the winding wheel. The winding housing has curtain exit openings at both the front and rear ends, with the other ends of the dustproof curtains passing through these openings and extending to the outside of the winding housing. A counterweight is fixedly mounted on the other end of each dustproof curtain, with two third magnets symmetrically fixedly mounted on the lower end of each counterweight. These third magnets are magnetically attracted to two second magnets. Four first magnets are symmetrically fixedly mounted on both the front and rear ends of the winding housing, positioned near the curtain exit openings. This musical instrument storage rack solves the problems of poor dust protection and portability found in existing musical instrument storage racks.

[0004] While the aforementioned existing technology can achieve dustproof treatment of the rack and can hold musical instruments such as horns, in actual use, the rack lacks an adjustment device, making it inconvenient and inflexible when the height of the rack needs to be adjusted, thus hindering the placement of musical instruments such as horns. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable mounting bracket for horns, so as to solve the problem that the lack of an adjustment device makes it inconvenient and inflexible to adjust the height of the mounting bracket when it is necessary to place horns and other musical instruments.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable speaker holder, comprising a base, with fixed seats fixedly installed on the left and right sides of the upper end of the base, an adjusting motor fixedly installed on the upper end of the fixed seats, the output end of the adjusting motor extending to the inner side of the fixed seats and fixedly installed with a lead screw, the end of the lead screw away from the adjusting motor being rotatably connected to the fixed seats, a threaded block being threadedly connected to the surface of the lead screw, a sliding groove being formed on the surface of the fixed seats, two sliding grooves being symmetrically arranged, a slider being slidably connected in the two sliding grooves, a positioning block being fixedly installed at one end of the slider, and a mounting bracket being connected to the other end of the two sliders together, and a fixing post being fixedly installed at the front end of the base.

[0007] Preferably, slide rails are fixedly installed at both the front and rear ends inside the fixed base, the slide rails are slidably connected to the positioning block, and the positioning block is fixedly connected to the threaded block.

[0008] Preferably, four rollers are installed at the lower end of the base, and a telescopic cylinder is fixedly installed at the left and right ends of the base.

[0009] Preferably, push plates are fixedly installed at the output ends of the two telescopic cylinders, and the lower ends of the two push plates are connected to a placement plate. A through-hole groove is provided in the placement plate, and four through-hole grooves are provided, with each through-hole groove corresponding to a roller.

[0010] Preferably, mounting bracket 2 and mounting bracket 3 are fixedly installed at the upper and lower ends of mounting bracket 1, and fixing plates are fixedly installed on the left and right sides of the front end of mounting bracket 1, mounting bracket 2 and mounting bracket 3.

[0011] Preferably, storage racks are slidably connected to the first, second, and third storage racks, and a spring is provided between each storage rack and the fixing plate. One end of the spring is fixedly connected to the fixing plate, and the other end of the spring is fixedly connected to the storage rack.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, when it is necessary to adjust the height of the placement rack, the adjustment motor drives the lead screw to rotate, so that the threaded block connected to the lead screw moves along the lead screw, and the positioning block fixedly connected to the threaded block slides along the slide rail direction, so that the slider fixedly connected to the positioning block slides along the slide groove direction, thereby driving the placement rack one, placement rack two and placement rack three to rise and fall. After the rise and fall is completed, the telescopic cylinder two pushes the top plate to push the storage rack, so that it is convenient for personnel to place the horn, etc. After the placement is completed, the storage rack is reset under the action of the spring, which increases the flexibility of the placement rack.

[0015] (2) In this utility model, when the placement rack needs to be moved, the telescopic cylinder retracts, causing the push plate to move the placement plate upward, so that the rollers protrude from the through hole groove and contact the ground, thereby facilitating the movement of the placement rack by personnel and improving convenience. When the placement rack is moved to the designated position, the telescopic cylinder pushes the push plate downward and makes the placement plate fit with the ground, making the placement rack more stable.

[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] Please see Figure 1-6 This utility model provides an embodiment of an adjustable speaker holder, comprising a base 1, with fixed seats 2 fixedly installed on the left and right sides of the upper end of the base 1. An adjusting motor 3 is fixedly installed on the upper end of the fixed seat 2, and the output end of the adjusting motor 3 extends to the inner side of the fixed seat 2 and is fixedly installed with a lead screw 4. The fixing method is through a motor bracket, and the adjusting motor 3 provides power for the rotation of the lead screw. The end of the lead screw 4 away from the adjusting motor 3 is rotatably connected to the fixed seat 2. A threaded block 6 is threadedly connected to the surface of the lead screw 4. Slide rails 5 are fixedly installed at the front and rear ends inside the fixed seat 2. The slide rails 5 and positioning blocks 51 are slidably connected. The stability of the device is improved by installing slide rails 5. The positioning blocks 51 and threaded blocks 6 are fixedly connected. The surface of the fixed seat 2 has a sliding groove 21, with two symmetrically arranged slide grooves 21. A slider 22 is slidably connected in the two slide grooves 21. A positioning block 51 is fixedly installed at one end of the slider 22, and the other ends of the two sliders 22 are connected to a mounting bracket 7. The mounting bracket 7 is raised or lowered by raising or lowering the positioning blocks 51.

[0025] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The lower end of the base 1 is equipped with four rollers 8, which facilitate the movement of the device. Telescopic cylinders 10 are fixedly installed at the left and right ends of the base 1. Push plates 11 are fixedly installed at the output ends of the two telescopic cylinders 10, which provide power for the lifting and lowering of the placement plate 12. The lower ends of the two push plates 11 are connected to the placement plate 12. There are four through-hole slots 13 in the placement plate 12. Each through-hole slot 13 corresponds to one of the rollers 8. The size of the through-hole slot 13 is larger than the size of the roller 8, and the lifting and lowering of the roller 8 is achieved by setting the through-hole slots 13.

[0026] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6The upper and lower ends of the first mounting frame 7 are respectively fixedly installed with the second mounting frame 71 and the third mounting frame 72. The left and right sides of the front end of the first mounting frame 7, the second mounting frame 71 and the third mounting frame 72 are fixedly installed with the fixing plates 701. The storage racks 702 are slidably connected to the first mounting frame 7, the second mounting frame 71 and the third mounting frame 72. A spring 703 is provided between each storage rack 702 and the fixing plate 701. One end of the spring 703 is fixedly connected to the fixing plate 701, and the other end of the spring 703 is fixedly connected to the storage rack 701. 2. Fixed connection: By setting a spring 703, the storage rack 702 can be retracted when it is extended, which improves convenience. A fixed column 9 is fixedly installed at the front end of the base 1. A telescopic cylinder 91 is fixedly installed at the upper end of the fixed column 9. A top plate 92 is fixedly installed at the output end of the telescopic cylinder 91. The top plate 92 is fitted and connected to the first mounting frame 7, the second mounting frame 71 and the third mounting frame 72. The top plate 92 extends out from the fixed plate 701, thereby completing the pushing of the storage rack 702.

[0027] Working principle: When placing musical instruments such as horns, the storage rack 702 can be pushed out by the telescopic cylinder 2 91. After the horn is placed, the storage rack 702 is retracted by the spring 703. Then, under the operation of the regulating motor 3, the first mounting rack 7 drives the second mounting rack 71 and the third mounting rack 72 to rise and fall, so as to facilitate the placement and retrieval of the horn by personnel.

[0028] When adjusting the placement rack, the adjusting motor 3 drives the lead screw 4 to rotate, causing the threaded block 6, which is threadedly connected to the lead screw 4, to move along the lead screw 4. This causes the positioning block 51 to move along the slide rail 5, thereby driving the slider 22 to slide along the slide groove 21, thus achieving the lifting and lowering of the placement rack 7. Under the action of the telescopic cylinder 91, the top plate 92 is pushed to push the storage rack 702 out, making it easy for personnel to put the horn into it. After placement, the telescopic cylinder 91 retracts the top plate 92, and under the action of the spring 703, the storage rack 702 retracts, thus completing the placement of the horn. The above work is repeated to achieve the purpose of storing the horn, improving convenience.

[0029] When the placement rack needs to be moved, the telescopic cylinder 10 drives the push plate 11 to retract, thereby causing the placement plate 12 to retract synchronously, and causing the roller 8 to protrude from the through hole groove 13 and fit against the ground, making it easier for personnel to push the placement rack and improving the flexibility of the device. When it is moved to the designated position, the telescopic cylinder 10 pushes the push plate 11 downward and causes the placement plate 12 to fit against the ground, thereby realizing the placement of the placement rack and increasing the stability of the device.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
