Description

Technical Field

[0001] The utility model relates to the technical field of brackets, in particular to a headphone rotating bracket with a built-in limiting structure. Background Technique

[0002] A headphone is a type of earphone that is worn on the head rather than inserted into the ear canal. The headphone usually consists of two parts, a signal transmitter and a headphone with a signal receiving and amplifying device (usually a dynamic coil type); a headphone bracket is a bracket used to support the headphone and is a common headphone accessory.

[0003] The utility model patent with the authorization announcement number CN205584445U discloses a headphone bracket, which includes a base, a support rod and a support. Among them, the base is a plate-like structure; the support rod is fixedly arranged on the base and extends upward, and the support is arranged at the top of the support rod. Arc-shaped support bodies are respectively arranged on both sides of the support, and the arc-shaped support bodies extend upward along both sides of the support. Card slots are respectively arranged on the two arc-shaped support bodies for placing the headphones. This bracket supports the headphone in a vertical manner, thereby minimizing the space occupied when the headphone is placed, and can be applied to personal use and headphone display cabinets and other occasions; the structure of the utility model is simple in design, and the headphone support is stable. The support is supported by a support rod vertically fixed on the base, arc-shaped support bodies are arranged on the front and back sides of the support, and card slots are respectively arranged at the middle positions of the two arc-shaped support bodies. The headphone is placed through the corresponding two card slots to achieve stable support of the headphone. At the same time, elastic support pieces are respectively arranged at the four corners of the bottom of the base to increase the friction between the base and the external plane and provide a buffering force.

[0004] Although this headphone bracket realizes stable support for the headphone, there are still the following problems when the device is actually used. Specifically: the device only supports the headphone through the support rod and the support. After the headphone is placed on the support, the angle and direction of the headphone are not convenient to adjust, and it is difficult to ensure that the headphone always remains in the best position, which will bring inconvenience to the user. In view of this, we propose a headphone rotating bracket with a built-in limiting structure. Content of the Utility Model

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] This embodiment provides a technical solution:

[0030] Please refer to Figures 1 - 5As shown, the earphone rotating bracket with a limiting structure comprises a base 1, a hollow shell 2 is fixed on the top of the base 1, a limiting block 21 is installed in the shell 2, a tooth plate 22 is installed on one side outer wall of the limiting block 21, and two sliding holes 211 are provided on the end surface of the limiting block 21 away from the tooth plate 22, and guide rods 25 are slidably installed in the sliding holes 211, the ends of the guide rods 25 are fixedly connected to the inner wall of the shell 2, and springs 26 for tightening the limiting block 21 are sleeved on the guide rods 25; a support rod 3 is provided above the shell 2, and the support rod 3 includes a bottom rod 30, the bottom rod 30 passes through the shell 2 and is rotatably connected to the shell 2, and a gear 31 is coaxially keyed at the bottom end of the bottom rod 30, and when the tooth plate 22 is meshed with the gear 31, the bottom rod 30 cannot rotate; a detachable top rod 33 is provided above the bottom rod 30; an earphone rack 4 is provided above the top rod 33, and a limiting plate 40 is installed at the top of the earphone rack 4 at the front and rear edges.

[0031] In this embodiment, the cross-section of the earphone stand 4 is C-shaped, and the earphone stand 4 is made of solid wood. The C-shaped design is compatible with the shape of the earphone, which is conducive to stably placing the earphone, and the solid wood material has the advantages of being strong and durable, ensuring the service life of the earphone stand 4.

[0032] In this embodiment, a horizontal plate 41 is fixed at the opening of the headphone rack 4, and a connecting bolt 42 is passed through the center of the horizontal plate 41; a threaded hole 332 is opened at the center of the top of the top rod 33, and the connecting bolt 42 is threadedly connected to the threaded hole 332. This design facilitates the assembly between the top rod 33 and the headphone rack 4, and improves the convenience of installation.

[0033] In this embodiment, a plug rod 32 is coaxially fixed at the top center of the bottom rod 30, a plug hole 331 is provided at the bottom of the top rod 33, and the plug rod 32 is plugged into the plug hole 331. This design facilitates the disassembly and assembly of the top rod 33 and the assembly of the support rod 3.

[0034] In this embodiment, a through slot 20 is provided at the top of the housing 2, a slider 23 is slidably mounted at the through slot 20, a push block 24 is mounted on the top of the slider 23, and the bottom end of the slider 23 is fixedly connected to the limit block 21. The push block 24 facilitates the adjustment of the horizontal position of the limit block 21, thereby facilitating the rotation of the bottom rod 30 or limiting the rotation of the bottom rod 30.

[0035] In this embodiment, the top of the push block 24 is provided with an inclined surface, and the push block 24 is made of plastic material. The push block 24 made of plastic material has the advantage of corrosion resistance, which ensures the service life of the push block 24, and the setting of the inclined surface facilitates pushing the push block 24.

[0036] In this embodiment, an adhesive layer 10 is coaxially fixed to the bottom of the base 1, and the adhesive layer 10 is a double-sided adhesive sticker. This design facilitates the stable installation of the base 1 on a desktop or the like, ensuring the stability and reliability of the device.

[0037] It should be added that the toothed plate 22 and the limiting block 21 in this embodiment are of an integrally formed structure. The integrally formed structure enhances the integrity and stability of the structure, and is less likely to loosen or break due to external factors such as vibration and impact, ensuring the limiting effect of the limiting block 21 on the bottom rod 30.

[0038] When the headset holder 4 needs to be adjusted, the user first pushes the push block 24 to one side. The push block 24 drives the slider 23 to slide along the through slot 20. The slider 23 drives the limiting block 21 to move horizontally. The guide rod 25 slides along the sliding hole 211, and the spring 26 is compressed by the limiting block 21. At the same time, the limiting block 21 drives the toothed plate 22 to disengage from the gear 31. Subsequently, the user holds the headset holder 4 and rotates it. The bottom rod 30 and the top rod 33 rotate synchronously. When the headset holder 4 rotates to an appropriate angle, the user releases the push block 24. Under the elastic action of the spring 26, the toothed plate 22 meshes with the gear 31, and the bottom rod 30 stops rotating, and the headset holder 4 stops rotating. Finally, the user places the headset between the two limiting plates 40 at the top of the headset holder 4.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
