They are adjustable components on mechanical or electronic equipment, typically changed by rotating them. They are widely used in various devices and systems, such as photoelectric sensors, effects processors, and oscilloscopes, to optimize performance, adapt to different working environments, or meet specific needs.

[0003] Most adjustment knobs on the market do not have a locking mechanism, which causes them to loosen when turned and automatically retract, thus affecting their performance. Therefore, a locking adjustment knob is needed to meet people's needs. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Given that most adjustment knobs on the market lack a locking mechanism, they may loosen during rotation, causing them to automatically retract and affecting their performance, a locking adjustment knob is needed to meet user needs.

[0006] Therefore, the purpose of this utility model is to provide an anti-loosening adjustment knob.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an anti-loosening adjustment knob, including a knob body, a protective shell welded to one end of the knob body, a knob rod body rotatably mounted inside the knob body and the protective shell via a bearing, and a circuit board welded to the outer wall of the knob rod body, a limit component hinged to the inner wall of the protective shell, an elastic lifting component installed on the inner wall of the protective shell, a first through hole opened on the side wall of the knob body, a ratchet body installed on the outer wall of the knob rod body, and a sealing hole opened at the top of the protective shell.

[0008] As a preferred embodiment of the anti-loosening adjustment knob of this utility model, a guide wheel body is welded and installed on the side wall of the knob body.

[0009] By adopting the above technical solution, this solution uses a guide wheel body, which allows the wire rope body to slide through the guide wheel body.

[0010] As a preferred embodiment of the anti-loosening adjustment knob of this utility model, the limiting component includes a hinge shaft, which is fixedly installed on the inner wall of the protective housing. An arc-shaped locking block is rotatably installed on the outer wall of the hinge shaft, and the arc-shaped locking block engages with the ratchet body.

[0011] By adopting the above technical solution, this solution uses an arc-shaped locking block to engage with the ratchet body, thereby ensuring that the ratchet body can only rotate clockwise and preventing it from rotating counterclockwise.

[0012] As a preferred embodiment of the anti-loosening adjustment knob of this utility model, the elastic lifting assembly includes a welding plate, which is fixedly installed on the inner wall of the protective shell. The welding plate has a second through hole inside, and a first vertical rod is provided inside the second through hole. The bottom end of the first vertical rod is hinged to the top end of the arc-shaped locking block, and a first horizontal plate is installed at the top end of the first vertical rod.

[0013] By adopting the above technical solution, the bottom end of the first vertical rod is hinged to the top end of the arc-shaped locking block, thereby causing the arc-shaped locking block to be squeezed and driving the first vertical rod to rise and fall.

[0014] As a preferred embodiment of the anti-loosening adjustment knob of this utility model, a high-pressure spring body is sleeved on the outer wall of the first vertical rod, and the top and bottom ends of the high-pressure spring body are fixedly connected to the bottom end of the first horizontal plate and the top end of the welding plate, respectively.

[0015] By adopting the above technical solution and through the design of the high-pressure spring body, the elastic recovery of the high-pressure spring body can drive the first horizontal plate and the first vertical rod to reciprocate up and down.

[0016] As a preferred embodiment of the anti-loosening adjustment knob of this utility model, the top of the first horizontal plate is equipped with a second vertical rod that passes through the sealing hole, and the top of the second vertical rod is equipped with a second horizontal plate. The top of the second horizontal plate is equipped with a steel wire rope body that passes through the guide wheel body and passes through the first through hole, and one end of the steel wire rope body is equipped with an installation ring body.

[0017] By adopting the above technical solution and through the design of the installation ring body, the steel wire rope body is driven by pulling the installation ring body, which in turn pulls the second vertical rod to rise and fall inside the sealing hole.

[0018] As a preferred embodiment of the anti-loosening adjustment knob of this utility model, a knob plate is installed at one end of the knob rod body, and anti-slip teeth are installed on the outer wall of the knob plate.

[0019] By adopting the above technical solution, anti-slip teeth are installed on the outer wall of the knob to prevent the operator from slipping when turning the knob.

[0020] The anti-loosening adjustment knob of this utility model has the following beneficial effects:

[0021] This invention firstly utilizes the interplay between an arc-shaped locking block and a ratchet body. By rotating the knob body clockwise, the ratchet body presses against the arc-shaped locking block, causing it to rotate. This rotation of the knob body then drives the circuit board to rotate simultaneously, allowing the operator to turn the adjustment knob. Simultaneously, the interplay between the ratchet body and the arc-shaped locking block prevents the knob body from rotating counterclockwise, thus improving the anti-loosening effect of the adjustment knob.

[0022] This invention firstly utilizes the interaction between an arc-shaped locking block and a ratchet body. As the ratchet body compresses the arc-shaped locking block to rotate, the arc-shaped locking block compresses the first vertical rod to slide inside the second through hole, causing the first horizontal plate to pull the high-pressure spring body, resulting in deformation. This allows the high-pressure spring body to elastically recover, causing the arc-shaped locking block to engage with the ratchet body. This prevents the knob body from retracting while rotating clockwise, thus ensuring the knob body is securely locked. Attached Figure Description

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0033] Example 1: Refer to Figures 1-4 This is the first embodiment of the present invention. This embodiment provides an anti-loosening adjustment knob, which addresses the issue that most adjustment knobs on the market lack an anti-loosening structure during use, causing them to loosen during rotation and automatically retract, thus affecting their performance. Therefore, an anti-loosening adjustment knob is needed to meet user needs. The knob includes a knob body 1, with a protective shell 2 welded to one end. A knob rod body 3, which passes through the protective shell 2, is rotatably mounted inside the knob body 1 and the protective shell 2 via a bearing. A circuit board 4 is welded to the outer wall of the knob rod body 3. A first through hole 101 is opened on the side wall of the knob body 1. A ratchet body 301 is installed on the outer wall of the knob rod body 3. A sealing hole 201 is opened at the top of the protective shell 2. A guide wheel body 102 is welded to the side wall of the knob body 1.

[0034] Combination Figure 1 and Figure 2In this embodiment of the utility model, a knob plate 5 is installed at one end of the knob rod body 3, and anti-slip teeth are installed on the outer wall of the knob plate 5. The anti-slip teeth on the outer wall of the knob plate 5 are used to prevent the operator from slipping when turning the knob plate 5.

[0035] The specific working principle is as follows: First, the arc-shaped locking block 602 cooperates with the ratchet body 301, so that the clockwise rotation of the knob rod body 3 drives the ratchet body 301 to squeeze the arc-shaped locking block 602, thereby causing the arc-shaped locking block 602 to rotate, so that the knob rod body 3 can rotate, thereby driving the circuit board 4 to rotate at the same time, so that the operator can turn the adjustment knob.

[0036] Example 2: Refer to Figures 1-4 This is the first embodiment of the present invention. This embodiment provides an anti-loosening adjustment knob, which addresses the issue that most adjustment knobs on the market lack an anti-loosening structure during use, causing them to loosen during rotation and automatically retract, thus affecting their performance. Therefore, an anti-loosening adjustment knob is needed to meet user needs. The inner wall of the protective housing 2 is hinged with a limiting component 6, and an elastic lifting component 7 is installed on the inner wall of the protective housing 2. The limiting component 6 includes a hinge shaft 601, which is fixedly installed on the inner wall of the protective housing 2. An arc-shaped locking block 602 is rotatably installed on the outer wall of the hinge shaft 601, and the arc-shaped locking block 602 engages with the ratchet body 301. By engaging the arc-shaped locking block 602 with the ratchet body 301, the ratchet body 301 can only rotate clockwise, preventing it from rotating counterclockwise.

[0037] Combination Figure 2 , Figure 3 and Figure 4 In an embodiment of this utility model, the elastic lifting assembly 7 includes a welding plate 701, which is fixedly installed on the inner wall of the protective housing 2. A second through hole 702 is provided inside the welding plate 701, and a first vertical rod 703 is provided inside the second through hole 702. The bottom end of the first vertical rod 703 is hinged to the top end of the arc-shaped locking block 602. A first horizontal plate 704 is installed on the top end of the first vertical rod 703. A high-pressure spring body 705 is sleeved on the outer wall of the first vertical rod 703, and the top and bottom ends of the high-pressure spring body 705 are fixedly connected to the bottom end of the first horizontal plate 704 and the top end of the welding plate 701, respectively. By hinged between the bottom end of the first vertical rod 703 and the top end of the arc-shaped locking block 602, the arc-shaped locking block 602 is compressed, thereby driving the first vertical rod 703 to rise and fall.

[0038] Combination Figure 2 , Figure 3 and Figure 4In this embodiment of the present invention, a second vertical rod 706 is installed at the top of the first horizontal plate 704, passing through the sealing hole 201, and a second horizontal plate 707 is installed at the top of the second vertical rod 706. A steel wire rope body 103 is installed at the top of the second horizontal plate 707, passing through the guide wheel body 102 and the first through hole 101. An installation ring body 104 is installed at one end of the steel wire rope body 103. Through the design of the installation ring body 104, the steel wire rope body 103 is driven by pulling the installation ring body 104, thereby pulling the second vertical rod 706 to rise and fall inside the sealing hole 201.

[0039] The specific working principle is as follows: First, by pulling the mounting ring body 104, the wire rope body 103 is driven to pass through the guide wheel body 102 and pull the second horizontal plate 707 and the second vertical rod 706 to rise and fall inside the sealing hole 201. This causes the second vertical rod 706 to rise and fall, which in turn causes the first horizontal plate 704 and the first vertical rod 703 to slide inside the second through hole 702 and compress the high-pressure spring body 705 to deform. This causes the first vertical rod 703 to rise and fall, which in turn drives the arc-shaped locking block 602 to rotate simultaneously. This prevents the arc-shaped locking block 602 from engaging with the ratchet body 301, allowing the operator to rotate the knob lever body 3 counterclockwise. Simultaneously, when the mounting ring body 104 is no longer pulled, the high-pressure spring body 705 elastically returns to its original position, causing the arc-shaped locking block 602 to rotate and engage with the ratchet body 301. This prevents the ratchet body 301 from rotating counterclockwise, thus achieving an anti-giveaway effect on the knob lever body 3.

[0040] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
