Description

Technical Field

[0001] This utility model relates to the field of metal knob technology, specifically a novel corrosion-resistant metal knob. Background Technology

[0002] As is well known, in many fields such as industrial control, home appliances, and instrumentation, knobs are a key component of the user interface, and their design quality and performance directly affect the overall user experience and lifespan of the equipment. However, traditional knob structures and technologies have a series of limitations and challenges. Traditional knobs mostly rely on a single rubber ring or gasket for sealing. This design may provide some waterproof and dustproof effect initially, but when exposed to humid, dusty, or chemical environments for a long time, the knobs will be corroded and damaged. Most knobs are installed on equipment through simple threaded connections or snap-fits, which are prone to loosening or even falling off after vibration, impact, or prolonged use. This not only affects normal use but may also lead to short circuits or other malfunctions in the internal circuitry. Existing designs usually lack effective mechanical locking devices to prevent knobs from accidentally falling off, especially in harsh working environments such as high-vibration machinery or high-frequency use. While ordinary metal materials are inexpensive, they are prone to rust and corrosion when exposed to acidic or alkaline environments, salt spray corrosion, or extreme climatic conditions, shortening the lifespan of the knobs and potentially affecting the appearance and function of the equipment. Therefore, it is necessary to propose solutions to this technical problem. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a novel corrosion-resistant metal knob.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel corrosion-resistant metal knob, comprising a knob body, the outer surface of which has an anti-corrosion coating, an adjusting ring on the knob body, a sliding mechanism between the adjusting ring and the knob body, a bearing seat at the bottom end of the adjusting ring, a sealing ring at the bottom end of the bearing seat, a suction cup at the bottom end of the sealing ring, and a sliding mechanism comprising a groove and a slide bar. The groove is formed on the inner wall of the adjusting ring, the slide bar is installed on the outer wall of the knob body, the slide bar passes through the groove, limiting plates are provided at both ends of the slide bar, and a sealing sleeve is provided on the groove.

[0007] Furthermore, the present invention is improved by providing reinforcing ribs inside the knob body.

[0008] Furthermore, an improvement of this utility model is that the reinforcing rib has a ring structure.

[0009] Furthermore, the present invention is improved in that the sliding mechanism is provided in multiple forms arranged in a circular array.

[0010] Furthermore, the present invention is improved in that both the suction cup and the sealing sleeve are made of high and low temperature resistant rubber.

[0011] Furthermore, an improvement of this utility model is that the knob body is made of aerospace-grade aluminum alloy.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a novel corrosion-resistant metal knob, which has the following characteristics:

[0014] Beneficial effects:

[0015] This new type of corrosion-resistant metal knob, through its sealing ring and suction cup structure, allows the suction cup to adhere tightly to the equipment surface when the adjusting ring is pushed downwards, forming the first physical barrier. This effectively prevents external moisture, dust, and other contaminants from entering the equipment. The sealing sleeve on the slide further ensures the seal between the suction cup and the sealing ring, preventing any possible leakage paths and ensuring the sealing integrity of the entire system. Even during rotation, the bearing seat design allows the knob body to drive the adjusting ring to rotate without affecting the suction cup's adsorption state, thus achieving continuous sealing protection under dynamic conditions. The outer surface of the knob body is covered with an anti-corrosion coating, such as a nickel-titanium alloy coating or other high-performance anti-corrosion materials, which greatly enhances the knob's corrosion resistance in harsh environments. This allows the knob to work stably for a long time under extreme conditions such as humidity, acid and alkali, and salt spray, extending the product's service life. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1-4 This utility model relates to a novel corrosion-resistant metal knob, comprising a knob body 1, the outer surface of which has an anti-corrosion plating layer 2, an adjusting ring 3 on which an adjusting ring 3 is provided, a sliding mechanism between the adjusting ring 3 and the knob body 1, a bearing seat 4 at the bottom end of the adjusting ring 3, a sealing ring 5 at the bottom end of the bearing seat 4, and a suction cup 6 at the bottom end of the sealing ring 5. The sliding mechanism includes a sliding groove and a sliding strip 7. The sliding groove is formed on the inner wall of the adjusting ring 3, and the sliding strip 7 is installed on the outer wall of the knob body 1, passing through the sliding groove. Limiting plates 8 are provided at both ends of the sliding strip 7, and a sealing sleeve 9 is provided on the sliding groove. In this embodiment, the knob body 1 is installed on the knob core of a designated device. To ensure sealing and prevent the knob body 1 from detaching from the knob core assembly, a sealing mechanism is used to... The adjusting ring 3 is pushed down, and the adjusting ring 3 slides linearly on the slide groove through the slide bar 7 in the sliding mechanism, so that the adjusting ring 3 moves linearly on the knob body 1. This allows the suction cup 6 at the bottom of the sealing ring 5 to abut against the flat surface of the equipment. The suction cup 6 can be stably attached to the flat surface of the equipment. The sealing sleeve 9 on the slide groove can ensure the sealing of the suction cup 6 and the internal space of the sealing ring 5, ensuring the stability of the adsorption. Then, the bearing seat 4 can make the knob body 1 drive the adjusting ring 3 to rotate. The bearing seat 4 can keep the suction cup 6 stably attached and will not follow the rotation angle of the adjusting ring 3. The suction cup 6 of the sealing sleeve 9 can ensure the sealing of the space at the connection between the knob body 1 and the knob core. The anti-corrosion coating 2 on the outer surface of the knob body 1 can improve the corrosion resistance of the knob body 1, increase its service life, and enable it to be used in relatively harsh environments.

[0023] In order to improve the structural strength of the knob body 1, in this solution, the knob body 1 is provided with a reinforcing rib 10 inside, which can improve the structural strength of the knob body 1.

[0024] The aforementioned reinforcing rib 10 can be of any structural type. In order to further improve the structural strength of the knob body 1, in this solution, the reinforcing rib 10 is in the form of a ring structure. By making the reinforcing rib 10 into a ring structure, the structural strength of the knob body 1 can be further improved.

[0025] In order to improve the stability of the adjustment ring 3 when it moves on the knob body 1, in this solution, the sliding mechanism is provided in a multiple and circular array. The moving stability of the adjustment ring 3 can be further improved by the multiple and circular array sliding mechanisms.

[0026] The suction cup 6 and the sealing sleeve 9 can be made of any material. In order to improve environmental adaptability, in this solution, the suction cup 6 and the sealing sleeve 9 are both made of high and low temperature resistant rubber. With the suction cup 6 and the sealing sleeve 9 made of high and low temperature resistant rubber, the sealing effect can be guaranteed in high and low temperature environments.

[0027] The knob body 1 can be made of any material. In order to further improve the structural strength, in this solution, the knob body 1 is made of aerospace-grade aluminum alloy. Aerospace-grade aluminum alloy has the characteristics of high structural strength, which can ensure the normal use of the knob body 1 in harsh environments and its long service life.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
