Description

Technical Field

[0001] This utility model belongs to the field of storage rack technology, specifically, it relates to a stacked storage rack with a speaker enclosure. Background Technology

[0002] Currently, acoustic dome technology is widely used in exhibitions, commercial advertising, public address systems, and other fields. Its core structure typically uses a top-mounted transparent acrylic hemispherical dome, combined with a speaker unit installed upwards in the center. Acoustic propagation is achieved through acoustic reflection from the inner wall of the hemisphere. With the rapid development of the cultural and entertainment industry, the annual production of acoustic domes has exceeded one million units. The production process involves multiple steps, including precision injection molding, electronic assembly, and acoustic tuning, placing higher demands on the reliability of the material handling system.

[0003] In the existing production system, sound-absorbing covers are usually temporarily stored and transferred using multi-layer storage racks. Conventional storage racks are composed of multi-layer shelf structures made of metal or plastic frames. Operators need to manually place the sound-absorbing covers one by one into the shelf grooves. When transfer is required, multiple storage racks are vertically stacked to form a transport unit using a forklift.

[0004] Existing storage racks may simply be inserted by gravity when stacked. Since there is no locking mechanism between the racks, they are prone to loosening during transportation due to vibration, which can lead to product damage or worker injury, further reducing the safety of using the storage racks. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a stackable storage rack for a sound-concentrating cover that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: a stackable storage rack for a soundbox cover, including a placement plate and several placement slots formed on the placement plate. The placement slots are used to store the soundbox covers. The interior of each placement slot has an insertion slot. The top of the placement plate has a positioning hole. A positioning rod is fixedly connected to the top of the positioning hole. The outer wall size of the positioning rod is adapted to the inner wall size of the positioning hole. A locking mechanism is provided inside the positioning rod. The locking mechanism includes a trapezoidal insert and a concave sliding plate that slide inside the positioning rod. An inclined groove is formed on the surface of the trapezoidal insert. A fixing rod is slidably connected inside the inclined groove. The fixing rod is fixedly connected to both sides of the concave sliding plate. The inner size of the trapezoidal insert is adapted to the insertion slot.

[0007] Preferably, a buffer plate is fixedly connected inside the positioning hole, and the buffer plate is used to support the bottom of the sound-absorbing cover.

[0008] Preferably, a buffer spring is fixedly connected inside the positioning hole, and a buffer plate is fixedly connected to the end of the buffer spring.

[0009] Preferably, a connecting rod is fixedly connected to the top of the concave sliding plate, the end of the connecting rod passes through the positioning rod and the placement plate and extends to the outside of the placement plate, and the end is fixedly connected to the connecting plate.

[0010] Preferably, a Z-shaped handle is fixedly connected to the side wall of the connecting plate, and the Z-shaped handle is slidably connected to the inner side wall of the placement plate.

[0011] Preferably, a compression spring is fixedly connected to the top of the connecting plate, and the end of the compression spring away from the connecting plate is fixedly connected to the inner sidewall of the placement plate.

[0012] Preferably, handles are fixedly connected to both sides of the placement plate, and the surface of the handles is provided with anti-slip texture.

[0013] Preferably, there are four sets of positioning holes and positioning rods, and the four sets of positioning holes and positioning rods are evenly distributed at the four corners of the placement plate.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0015] The speaker enclosure features a stackable storage rack that, through the cooperation of trapezoidal inserts, concave sliding plates, inclined grooves, and fixing rods, allows multiple storage racks to lock together, thus preventing them from loosening due to vibration during handling. This reduces the risk of product damage or worker injury and significantly improves the stability and safety of multi-layer stacking. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0024] Example 1:

[0025] Reference Figures 1-5 A stackable storage rack for a soundbox cover includes a placement plate 1 and several placement slots 2 formed on the placement plate 1. The placement slots 2 are used to store the soundbox covers. The interior of the placement slots 2 has an insertion slot 21. The top of the placement plate 1 has a positioning hole 3. A positioning rod 4 is fixedly connected to the top of the positioning hole 3. The outer wall size of the positioning rod 4 is adapted to the inner wall size of the positioning hole 3. A locking mechanism 5 is provided inside the positioning rod 4. The locking mechanism 5 includes a trapezoidal insert 51 and a concave sliding plate 52 that slide inside the positioning rod 4. The surface of the trapezoidal insert 51 has an inclined groove 53. A fixing rod 54 is slidably connected inside the inclined groove 53. The fixing rod 54 and the concave sliding plate 52 are connected to the locking mechanism 53. The two sides of the concave sliding plate 52 are fixedly connected. The trapezoidal insert 51 is adapted to the inner dimensions of the insertion slot 21. The top of the concave sliding plate 52 is fixedly connected to a connecting rod 55. The end of the connecting rod 55 passes through the positioning rod 4 and the placement plate 1 and extends to the outside of the placement plate 1. The end is fixedly connected to a connecting plate 56. The top of the connecting plate 56 is fixedly connected to a compression spring 58. The end of the compression spring 58 away from the connecting plate 56 is fixedly connected to the inner wall of the placement plate 1. Both sides of the placement plate 1 are fixedly connected to handles 6. The surface of the handles 6 is provided with anti-slip texture. There are four sets of positioning holes 3 and positioning rods 4. The four sets of positioning holes 3 and positioning rods 4 are evenly distributed at the four corners of the placement plate 1.

[0026] In this utility model, the top placement slot 2 of 1 is used to independently store the sound chamber cover. With the opening of the top positioning hole 3 of 1, when two 1s are assembled and stacked, the positioning rod 4 at the bottom of the upper 1 is inserted into the positioning hole 3 at the top of the lower 1, thereby realizing the stacking combination of multiple 1s. This plug-in structure design greatly increases the flexibility of the storage rack. The height of the storage rack can be adjusted according to actual needs, significantly improving space utilization and meeting the requirements for storing large quantities of sound chamber covers. In addition, when the positioning rod 4 is inserted into the positioning hole 3, the trapezoidal insert 51 inside the positioning rod 4 will be squeezed and move inward. When the trapezoidal insert 51 coincides with the insertion slot 21, the trapezoidal insert 51 will be inserted into the insertion slot 21 and locked, thereby locking the positioning hole 3 and the positioning rod 4. This ensures that multiple 1s are not easy to detach after being stacked, and further ensures the connection strength of multiple stacked 1s.

[0027] When it is necessary to disassemble the positioning hole 3 and the positioning rod 4, move the concave sliding plate 52 upward, causing the fixing rod 54 to move synchronously. At this time, the fixing rod 54 slides in the inclined groove 53. Since the inclined groove 53 is inclined, it will move the trapezoidal insert 51 into the positioning rod 4, thus separating the trapezoidal insert 51 from the insertion groove 21. At this time, the positioning hole 3 and the positioning rod 4 can be disassembled. The connecting plate 56 is connected by the connecting rod 55 at the top of the concave sliding plate 52. At this time, controlling the connecting plate 56 alone can move both sets of concave sliding plates 52 upward at the same time. At the same time, the Z-shaped handle 57 on the side wall of the connecting plate 56 facilitates single-finger operation by the user. Under the action of the compression spring 58, a compressive force can be applied to the top of the connecting plate 56. In this way, when the connecting plate 56 is not subjected to an upward pulling force, the connecting plate 56, the connecting rod 55, and the concave sliding plate 52 can be automatically reset. The side wall handle 6 of 1 makes it easy for the staff to hold and move 1. When it is necessary to disassemble the positioning hole 3 and the positioning rod 4, the concave sliding plate 52 is moved upward, which drives the fixing rod 54 to move synchronously, increasing the friction of the staff's hands. The four sets of positioning holes 3 and positioning rods 4 can be evenly distributed at the four corners of 1, forming four stable feet to support 1 and effectively prevent the sound-absorbing cover from shaking and slipping during transportation.

[0028] Example 2:

[0029] Reference Figure 2 , Figure 3 and Figure 5 Similar to Embodiment 1, but further: a buffer plate 31 is fixedly connected inside the positioning hole 3, the buffer plate 31 is used to support the bottom of the sound-absorbing cover, and a buffer spring 32 is fixedly connected inside the positioning hole 3, the end of the buffer spring 32 is fixedly connected to the buffer plate 31.

[0030] With the internal buffer plate 31 of the positioning hole 3, when the speaker enclosure is stored inside the positioning hole 3, the buffer plate 31 provides auxiliary support for the bottom of the speaker enclosure, thereby ensuring the installation stability of the speaker enclosure. Furthermore, the buffer spring 32 applies a pushing force to the bottom of the buffer plate 31 to adaptively adjust the buffer plate 31, so that the buffer plate 31 can provide adaptive support according to the height of the speaker enclosure.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model.
