Description

Technical Field

[0001] This utility model relates to the field of metal knob technology, and more specifically, to a metal knob with a heat insulation component. Background Technology

[0002] Existing metal knobs, with their advantages of robust structure, wear resistance, durability, and high mechanical strength, are widely used in various fields such as kitchen appliances, industrial heating equipment, and mechanical equipment control systems, becoming the core control component for starting and stopping equipment and adjusting parameters.

[0003] In high-temperature operating environments such as ovens, gas stoves, and industrial furnaces, the material properties of metal knobs make them prone to rapidly conducting heat from the equipment itself. This causes the knob surface temperature to rise sharply, which can not only easily burn the operator's hands, but also cause the seals and connectors at the connection between the knob and the equipment to age and fail due to continuous high temperatures, thus shortening the equipment's lifespan.

[0004] To solve the heat insulation problem, existing technologies often employ solutions such as wrapping heat insulation cotton around the surface of metal knobs, spraying heat insulation coatings, or adding plastic shells. However, heat insulation cotton is prone to aging and falling off due to long-term high temperatures, and is difficult to clean. Heat insulation coatings have limited thickness and are prone to wear and failure after long-term use, resulting in a significant decrease in heat insulation performance.

[0005] While plastic casings can block some heat, they are mostly fixed designs, and the length of the handle is difficult to adjust, making it difficult to accommodate different operator hand sizes and equipment installation space differences. Utility Model Content

[0006] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a metal knob with a heat insulation component to solve the technical problem mentioned in the background art that the surface temperature of the knob rises sharply, which can easily cause burns to the operator's hands.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A metal knob with a heat insulation component includes a connecting knob, symmetrical slide rails on both outer walls of the connecting knob, movable blocks in damping sliding connection on the slide rails, protective knobs on the outer sides of the two movable blocks, locking devices on one end of each side wall of the protective knob, multiple evenly distributed fixing holes on the side walls of the slide rails, the locking devices being adapted to the fixing holes, and a handheld component on the outer side of the protective knob.

[0008] The present invention is further configured such that the locking device includes a protective box, a spring, a locking block, a limiting block, and a hand lever. The protective box is symmetrically arranged on the side wall of the protective button. The limiting block is on one side of the protective box and slidably connected thereto. One end of the spring is connected to the protective box, and the other end is connected to the limiting block. The locking block is at one end of the limiting block, and the locking block passes through the fixing hole and is slidably connected thereto. The hand lever passes through the protective box and is slidably connected thereto. One end of the hand lever is connected to the limiting block, thereby achieving a stable locking of the protective button position and preventing the protective button from shifting due to equipment vibration during operation.

[0009] The present invention is further configured such that the handheld component includes a handheld box, a handheld block, and a pin. The handheld box is located on the front side wall of the protective button. The handheld block passes through the handheld box and is slidably connected to it. The side wall of the handheld block is provided with multiple limiting holes. The pin passes through the handheld box and the limiting holes and is slidably connected to them, thus adapting to the hand size of different operators and the spatial differences in equipment installation.

[0010] The present invention is further provided with a heat insulation pad inside the protective button, and a high-temperature resistant adhesive layer is provided between the heat insulation pad and the protective button, which can effectively block the heat conducted by the connecting button and ensure operational safety.

[0011] The present invention is further configured such that a connecting block is provided on one side of the connecting button, and an inner shaft is provided on one side of the connecting block. The inner shaft is snapped together with the connecting block, so that the assembly and disassembly of the two can be completed quickly without the aid of special tools.

[0012] The present invention is further provided that the side wall of the connecting block is provided with scale lines, which are evenly distributed along the circumference of the connecting block, and can provide a clear positioning reference when the knob is rotated for adjustment.

[0013] The present invention is further provided that the outer side of the spring is fitted with a high-temperature resistant protective sleeve, which can isolate the spring from damage caused by the high-temperature environment.

[0014] (III) Beneficial Effects Compared with the prior art, this utility model provides a metal knob with a heat insulation component, which has the following advantages: 1. The slide rails on both sides of the connecting button and the moving block of the protective button are connected by damping, allowing the protective button to be freely adjusted in position according to the size of the operating space and the operator's usage habits. The locking device continuously pushes the limit block with the elastic potential energy of the spring, so that the locking block is accurately embedded in the fixing hole of the slide rail, forming a firm lock, effectively resisting the vibration and impact of the equipment during operation and preventing the protective button from being accidentally displaced.

[0015] 2. The protective button itself acts as an isolation barrier between the connecting button and the operator. Together with the assembly structure of the moving block and slide rail, it further blocks the heat conduction path, significantly reduces the surface temperature of the knob, fundamentally avoids the risk of high-temperature burns, and ensures operational safety in high-temperature work scenarios.

[0016] 3. The sliding connection design between the hand block and the hand box allows operators to flexibly adjust the extension length of the hand block according to their hand size, grip habits, and space limitations of the equipment installation. When the hand is small or the operating space is small, the extension distance of the hand block can be shortened to avoid interference. When the hand is large or a more stable grip is required, the length of the hand block can be extended to increase the grip contact area and improve the comfort and force stability during operation.

[0022] Please see Figure 1-5 A metal knob with a heat insulation component includes a connecting knob 1. Symmetrical slide rails 2 are provided on the outer walls of both sides of the connecting knob 1. Moving blocks 3 are provided on the slide rails 2 and are slidably connected to them. Protective knobs 4 are provided on the outer sides of the two moving blocks 3. Locking devices are provided at one end of each of the two side walls of the protective knobs 4. Multiple evenly distributed fixing holes 5 are provided on the side walls of the slide rails 2. The locking devices are adapted to the fixing holes 5. A hand-held component is provided on the outer side of the protective knobs 4.

[0023] The locking device includes a protective box 6, a spring 7, a locking block 8, a limiting block 9, and a hand lever 10. The protective box 6 is symmetrically arranged on the side wall of the protective button 4. The limiting block 9 is on one side of the protective box 6 and is slidably connected to it. One end of the spring 7 is connected to the protective box 6, and the other end is connected to the limiting block 9. The locking block 8 is at one end of the limiting block 9. The locking block 8 passes through the fixing hole 5 and is slidably connected to it. The hand lever 10 passes through the protective box 6 and is slidably connected to it. One end of the hand lever 10 is connected to the limiting block 9.

[0024] A connecting block 15 is provided on one side of the connecting button 1, and an inner shaft 16 is provided on one side of the connecting block 15. The inner shaft 16 is snapped into the connecting block 15.

[0025] The spring 7 is fitted with a high-temperature resistant protective sleeve on its outer side.

[0026] In this embodiment, the operator aligns the inner shaft 16 with the snap-fit ​​structure of the connecting block 15 and gently pushes the inner shaft 16 to complete the snap-fit ​​connection, making the inner shaft 16 and the connecting block 15 firmly connected. Then, the entire knob assembly is installed on the control shaft of the equipment through the connecting block 15. After assembly, the relative position of the protective button 4 and the connecting button 1 needs to be adjusted according to the heat generation of the equipment to achieve precise heat insulation. When the equipment generates a lot of heat (such as high-temperature baking or high-intensity heating conditions), the operator holds the hand handles 10 on both sides of the protective button 4 and pulls them outward. The hand handles 10 drive the limiting block 9 to slide in the protective box 6, while compressing the spring 7 (the high-temperature resistant protective sleeve on the outside of the spring 7 can insulate the heat and prevent the spring 7 from aging due to heat). The limiting block 9 drives the locking block 8 to disengage from the fixing hole 5 of the slide rail 2, releasing the position lock of the protective button 4. Then, push or pull the protective button 4. The protective button 4 drives the moving blocks 3 on both sides to slide along the slide rail 2 of the connecting button 1 with damping, increasing the distance between the protective button 4 and the connecting button 1, expanding the heat insulation space to enhance the heat insulation effect.

[0027] More specifically, after adjusting to the appropriate position, the hand lever 10 is released, and the spring 7 pushes the limit block 9 to reset under the action of elastic potential energy, causing the locking block 8 to re-pass through the corresponding fixing hole 5 on the slide rail 2, thus completing the position locking of the protective button 4. If the equipment generates less heat, the protective button 4 can be pushed closer to the connecting button 1 according to the same unlocking process to reduce the distance between the two to ensure ease of operation. During the operation of the equipment, the operator holds the hand-held component on the outside of the protective button 4 and rotates the knob. The protective button 4 drives the connecting button 1 to rotate synchronously through the connection of the moving block 3 and the slide rail 2. The connecting button 1 drives the inner shaft 16 to rotate through the connecting block 15, thereby controlling the operating parameters of the equipment (such as temperature, speed, etc.). During this process, the protective button 4 always acts as an isolation barrier between the operator and the high-temperature connecting button 1, and the adjusted distance achieves effective heat insulation to avoid burns.

[0028] Please see Figures 1-5 As one embodiment of the handheld component: the handheld component includes a handheld box 11, a handheld block 12 and a pin 13. The handheld box 11 is located on the front side wall of the protective button 4. The handheld block 12 passes through the handheld box 11 and is slidably connected to it. The side wall of the handheld block 12 is provided with a plurality of limiting holes. The pin 13 passes through the handheld box 11 and the limiting holes and is slidably connected to them.

[0029] Specifically, adjust the handheld component according to the size of your hand or the required operating space, pull out the pin 13 to release the lock of the handheld block 12, push the handheld block 12 to slide along the handheld box 11 to the appropriate extension length, and then insert the pin 13 through the handheld box 11 and the corresponding limiting hole to complete the fixation.

[0030] Please see Figures 1-5As one embodiment of the heat insulation pad 14: a heat insulation pad 14 is provided on the inner side of the protective button 4, and a high-temperature resistant adhesive layer is provided between the heat insulation pad 14 and the protective button 4.

[0031] Specifically, the heat insulation pad 14 effectively blocks the heat conducted by the connecting button 1, and the high-temperature resistant adhesive layer ensures that the heat insulation pad 14 does not fall off in high-temperature environments and always maintains a stable heat insulation effect.

[0032] Please see Figures 1-5 As one embodiment of the scale line 17: the side wall of the connecting block 15 is provided with scale line 17, and the scale line 17 is evenly distributed along the circumference of the connecting block 15.

[0033] Specifically, during the rotation process, the rotation amplitude can be visually observed through the scale lines 17 evenly distributed around the side wall of the connecting block 15, thus enabling precise adjustment of parameters.

[0034] In summary, when using the overall equipment: First, the basic assembly of the device is carried out. The staff first aligns the inner shaft 16 with the snap-fit ​​structure of the connecting block 15, and gently pushes the inner shaft 16 to complete the secure engagement of the two. This snap-fit ​​connection method does not require special tools, which greatly improves the assembly efficiency. Then, the entire knob assembly is connected and installed with the control shaft of the equipment through the connecting block 15, so that the knob and the equipment form a stable transmission connection, laying the foundation for subsequent operation.

[0035] After assembly, the relative positions of the protective button 4 and the connecting button 1 need to be adjusted according to the actual heat generation of the equipment to achieve adaptive heat insulation. When the equipment is in a high-heat condition, the operator holds the hand levers 10 on both sides of the protective button 4 and pulls them outward. The hand levers 10 drive the limit block 9 to slide horizontally in the protective box 6, while compressing the spring 7 which is fitted with a high-temperature resistant protective sleeve. The high-temperature resistant protective sleeve can effectively isolate the heat conducted by the equipment and prevent the spring 7 from experiencing elastic decay or aging and breakage in a high-temperature environment.

[0036] As the limiting block 9 slides, the locking block 8 at its end simultaneously disengages from the fixing hole 5 of the slide rail 2, releasing the position lock of the protective button 4. At this time, the operator can push or pull the protective button 4. The protective button 4 drives the moving blocks 3 on both sides to slide along the slide rail 2 on the outer wall of the connecting button 1 with damping. The damping characteristics make the sliding process smooth and without jamming until the distance between the protective button 4 and the connecting button 1 reaches the heat insulation requirements for high-heat scenarios. After adjustment, the hand lever 10 is released, and the spring 7 pushes the limiting block 9 to reset under the action of elastic potential energy, driving the locking block 8 to re-penetrate through the corresponding fixing hole 5 on the slide rail 2, completing the position lock of the protective button 4. At this time, the heat insulation pad 14 fixed by the high-temperature resistant adhesive layer on the inner side of the protective button 4 is simultaneously in place. The high-temperature resistant adhesive layer can ensure that the heat insulation pad 14 does not fall off in the high-temperature environment and always fits tightly with the protective button 4 to block heat.

[0037] If the heat output of the device decreases significantly, follow the same unlocking procedure to push the protective button 4 closer to the connecting button 1, reducing the distance between the two to balance heat insulation effect and ease of operation.

[0038] After the position of the protective button 4 is determined, the operator needs to adjust the handheld component to improve the operating comfort according to their own hand size, grip habits or the space limitations of the equipment installation. First, pull out the pin 13 that passes through the handheld box 11 and the handheld block 12 to release the position lock of the handheld block 12. Then, push the handheld block 12 to slide along the handheld box 11 and adjust its extension length. If the hand is small or the operating space is narrow, shorten the extension length to avoid interference. If the hand is large or a stable force is required, extend the length to increase the grip contact area. After the handheld block 12 is adjusted to a suitable position, put the pin 13 back through the handheld box 11 and insert it into the corresponding limiting hole on the side wall of the handheld block 12 to complete the position fixation of the handheld block 12 and ensure that the handheld block 12 will not move due to vibration or force during subsequent operation.

[0039] During equipment operation, the operator holds and rotates the adjusted hand block 12. The hand block 12 drives the protective button 4 to rotate synchronously through the hand box 11. The protective button 4 drives the connecting button 1 to rotate. The connecting button 1 then drives the inner shaft 16 to rotate through the connecting block 15, ultimately achieving the adjustment of equipment operating parameters (such as temperature, speed, etc.).

[0040] During this process, the scale lines 17 evenly distributed circumferentially on the side wall of the connecting block 15 play a key role. Operators can intuitively and accurately control the adjustment amount by observing the rotation range of the scale lines 17, thus avoiding the impact on the equipment's operating status due to excessive or insufficient adjustment.

[0041] When the knob needs maintenance or replacement, the operator can pull the inner shaft 16 in the opposite direction to release its snap connection with the connecting block 15 and quickly remove the entire knob assembly from the equipment. If the position of the handheld component or the protective button 4 needs to be adjusted, simply repeat the corresponding unlocking process. The entire maintenance process does not require complicated tools and is convenient and efficient.
