Abstract
Description
Technical Field
[0001] This utility model relates to the field of audio height adjustment technology, and in particular to an independent height adjuster that prevents tipping. Background Technology
[0002] In the field of audio equipment, in order to meet the sound effect requirements and aesthetics of different scenarios, it is often necessary to adjust the height and tilt angle of the speaker frame using an independent height adjuster. Existing independent height adjusters used for speaker frames mostly adopt a single column or single fulcrum support structure, which generally suffers from insufficient stability during the adjustment process.
[0003] When users adjust the height or angle of the speaker frame according to the listening environment, the center of gravity of the speaker body will change dynamically with the adjustment, and the frame may be unevenly stressed due to factors such as uneven placement or external contact. This can easily cause the height adjuster to tilt or even fall over, which will not only affect the normal sound effect of the speaker, but may also cause the speaker equipment to fall and be damaged. In severe cases, it may even cause safety accidents due to tipping and collision.
[0004] Therefore, this utility model provides an independent height adjuster to prevent tipping. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an independent height adjuster that prevents tipping.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: an anti-tipping independent height adjuster, including a column and an extension rod, and a connecting assembly, wherein the connecting assembly includes a connecting column fixedly connected inside the extension rod, an operating panel is sleeved on the outside of the connecting column, and a plurality of locking blocks are fixedly connected to the end of the operating panel away from the connecting column.
[0007] An adjustment assembly includes an extension rod 2 rotatably connected to the outside of a connecting column, the extension rod 2 having an engagement hole inside, and a torque assembly provided on the outside of the connecting assembly.
[0008] In a preferred embodiment, the torque assembly includes a threaded groove formed on the outside of the connecting post, and the connecting post is threadedly connected to a nut through the threaded groove.
[0009] In a preferred embodiment, an operating handle is fixedly connected to the end of the extension rod away from the connecting post.
[0010] In a preferred embodiment, the bottom end of the nut contacts the top end of the operating disc.
[0011] In a preferred embodiment, the engaging hole engages with the engaging block.
[0012] In a preferred embodiment, the bottom end of the operating panel is in contact with the top end of the extension rod.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] This invention uses an operating handle to rotate the extension rod two around the connecting column, causing the locking hole inside the extension rod two to engage with the locking block on the connecting component, thus achieving a stable connection of the extension rod two on the height adjuster. Then, by rotating the nut, it moves on the threaded groove, changing the pressure on the operating panel, thereby adjusting the overall height. This design achieves structural stability and precise height adjustment, allowing for flexible adjustment of the device height according to actual usage scenarios. It effectively addresses uneven stress caused by dynamic changes in the speaker's center of gravity, uneven placement surfaces, and external impacts, reducing the risk of the height adjuster tilting or even tipping over.

[0025] 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.
[0026] like Figure 1 - Figure 3 As shown, this embodiment provides a technical solution: an anti-tipping independent height adjuster, including a column 1 and an extension rod 2, and a connecting component 3. The connecting component 3 includes a connecting column 31 fixedly connected inside the extension rod 2. An operating panel 32 is sleeved on the outside of the connecting column 31. The bottom end of the operating panel 32 contacts the top end of the extension rod 2. A plurality of locking blocks 33 are fixedly connected to the end of the operating panel 32 away from the connecting column 31.
[0027] The column 1, as the main support structure of the entire height adjuster, bears the weight of the extension rod 2 and other components, and provides basic stability and height reference for the entire device. The extension rod 2 connects to the column 1 to further elevate the entire device. On the other hand, it provides an installation space for the connecting component 3, allowing the connecting component 3 to be operated and fixed inside. The connecting column 31, as the core component of the connecting component 3, is fixedly connected inside the extension rod 2, providing support for the operating panel 32 and serving as the basic connection point for the entire connecting component 3. The bottom of the operating panel 32 contacts the top of the extension rod 2, serving as a transition and support. At the same time, it provides an installation base for the locking block 33, allowing the locking block 33 to be fixedly connected to it. It can also engage with the locking hole 42 of the extension rod 41 through its own structure. The locking block 33 engages with the locking hole 42 inside the extension rod 41, realizing the fixed connection between the extension rod 41 and the connecting component 3, thereby allowing the extension rod 41 to be stably installed on the height adjuster.
[0028] like Figure 4 - Figure 5 As shown, the adjustment component 4 includes an extension rod 41 rotatably connected to the outside of the connecting post 31. The extension rod 41 has a locking hole 42 inside. An operating handle 43 is fixedly connected to one end of the extension rod 41 away from the connecting post 31. The locking hole 42 engages with the locking block 33.
[0029] The extension rod 41 engages with the locking block 33 of the connecting component 3 through the internal locking hole 42, thus connecting with the height adjuster body. An operating handle 43 is fixedly connected to the outside, allowing the operator to rotate the extension rod 41 by operating the handle 43. The locking hole 42 engages with the locking block 33, realizing the detachable connection between the extension rod 41 and the connecting component 3. It is a key component connecting the adjusting component 4 and the connecting component 3. The operating handle 43 is fixedly connected to the end of the extension rod 41 away from the connecting post 31, so as to facilitate the operator to rotate the extension rod 41, thereby realizing the height adjustment function of the height adjuster.
[0030] like Figure 4 - Figure 5 As shown, a torque assembly 5 is provided on the outer side of the connecting assembly 3. The torque assembly 5 includes a threaded groove 51 formed on the outer side of the connecting post 31, and a nut 52 is threadedly connected to the connecting post 31 through the threaded groove 51. The bottom end of the nut 52 contacts the top end of the operating disc 32.
[0031] Threaded groove 51: It is opened on the outside of the connecting post 31 and is used to connect with the nut 52 by thread. It provides the basic structure for torque adjustment. Nut 52: It is connected to the threaded groove 51 by thread. Its bottom end contacts the top end of the operating plate 32. When the nut 52 is rotated, the pressure of the nut 52 on the operating plate 32 can be changed, thereby adjusting the friction between the connecting assembly 3 and the extension rod 41, and realizing the torque adjustment.
[0032] Working principle:
[0033] like Figure 1 - Figure 5 As shown:
[0034] In use: First, the operator needs to rotate the operating handle 43, which will cause the extension rod 41 to rotate around the connecting post 31. As the extension rod 41 rotates, the engaging hole 42 inside the extension rod 41 will rotate accordingly relative to the locking block 33 on the connecting assembly 3. When the engaging hole 42 and the locking block 33 are precisely engaged, the extension rod 41 can be stably connected to the height adjuster, ensuring the stability of the entire structure. At this time, the operator continues to rotate the nut 52, which will move along the thread direction on the threaded groove 51. This movement can change the pressure on the operating disc 32. As the pressure increases or decreases, the operating disc 32 will decrease accordingly, thereby adjusting the overall height. Conversely, by engaging the engaging hole 42 and the locking block 33, the operating disc 32 will rotate on the connecting post 31, allowing for upward adjustment.
[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
