Description

Technical Field

[0001] The present invention relates to the technical field of switches, and particularly to a switch device with a time-delay function. Background Art

[0002] In the existing electrical control systems, time relays are generally used in switch devices to achieve the time-delay function. As an electrical component, the core function of a time relay is to introduce a time delay into the circuit, thereby controlling the on-off state of the circuit and realizing specific control logics. This technology has been widely applied in industrial automation, household appliances, and various mechanical equipment.

[0003] However, although time relays can achieve the time-delay control function to a certain extent, their inherent defects as electrical components cannot be ignored. The interior of a time relay contains complex mechanical structures and electronic components, which are prone to being affected by environmental factors during long-term operation, resulting in performance degradation or even failure. Once a time relay fails, its time-delay function cannot be guaranteed, which may further lead to the entire system being unable to operate properly. More seriously, in some critical fields (such as power systems, aerospace, medical equipment, etc.), the failure of a time relay may trigger a chain reaction, causing serious consequences such as equipment damage and casualties. Summary of the Invention

[0013] Additional aspects and advantages of the present invention will be given in part in the following description, will become apparent in part from the following description, or will be understood through the practice of the present invention.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The structure of the present invention is compact and exquisitely designed, facilitating installation and maintenance. It adopts a mechanical delay structure, which is more stable and reliable than traditional time relays, with a low failure rate. It can meet different time delay requirements. By simply adjusting the angle of the knob, the delay time can be controlled, with convenient operation and good usage effects. 2. The present invention proposes an innovative design of the delay mechanism, which integrates core components such as a lifting frame, a delay spring, a piston, an expanded-diameter slider, a double-layer hollow cylinder, silicone oil, and a damping ring. Its essence lies in using the inherent elasticity of the delay spring as the driving force for the delay process. By precisely regulating the resistance encountered by the piston in the silicone oil medium, this mechanism can efficiently control the delay duration. To achieve precise regulation of the delay time, the present invention mainly adopts the following three strategies: First, by adjusting the total filling amount of silicone oil in the double-layer hollow cylinder, it directly affects the magnitude of the resistance that the piston needs to overcome during movement, thereby achieving preliminary regulation of the delay time. Second, changing the installation quantity of the damping ring. The increase or decrease of the damping ring directly affects the resistance received during the movement of the vertical section, providing further adjustment space for the delay time. Finally, by adjusting the contact area or volume between the expanded-diameter slider and the silicone oil, the fluid resistance received by the expanded-diameter slider during movement in the silicone oil can be flexibly changed. This fine adjustment of the resistance can directly affect the delay effect. The design of this triple-delay mechanism not only ensures that normal use can still be maintained through other mechanisms in case of a single component failure, greatly improving the reliability and practicality of the device, but also facilitates the model division of the control switch device according to the delay time. The quantity of silicone oil and damping rings can be preset and installed before leaving the factory to ensure a fixed delay time range; while the contact area or volume between the expanded-diameter slider and the silicone oil can be freely adjusted by the user according to actual needs after leaving the factory to achieve fine-tuning within the specified time range, meeting the delay requirements in diverse application scenarios, with excellent usage effects. 3. The double-layer hollow box body and the double-layer hollow cylinder carefully designed in the present invention both adopt a clever double-layer hollow structure and are combined with a strict vacuum pumping treatment process. This unique design significantly reduces the potential interference of the external environment on the performance of the internal delay spring and the properties of the silicone oil, ensuring the long-term stability of the delay spring elasticity and the silicone oil resistance. This innovative measure not only optimizes the usage effects but also enables the delay mechanism to exhibit excellent performance under various environmental conditions, demonstrating outstanding reliability and stability. 4. The present invention creatively incorporates an advanced variable-diameter adjustment mechanism, which is specifically designed for operators. Through a single-key operation, synchronous adjustment of multiple groups of diameter-expanding sliders can be achieved, thus easily realizing precise control of resistance and delay time. This innovation not only significantly enhances the flexibility and practicality of the delay mechanism, enabling it to adapt to more diverse application scenarios, but also brings a more convenient and efficient operation experience to users. Whether in the scientific research field that pursues precise delay control or in industrial applications that require flexible adjustment of delay effects, the present invention demonstrates excellent performance and broad application prospects; 5. The present invention ingeniously introduces an external adjustment gear design, allowing operators to easily control from the outside of the double-layer hollow box body, driving the internal tooth column to rotate, and achieving efficient single-key adjustment, greatly improving the operation efficiency. The external adjustment gear design is particularly refined: one end is internally provided with precise teeth to ensure seamless meshing with the tooth column and smooth driving; the other end is equipped with intuitive scale markings, enabling operators to immediately grasp the current parameters at a glance, realizing precise adjustment while further improving the operation efficiency. This user-friendly design not only greatly enhances the convenience of use, but also optimizes the overall performance, offering users a more efficient and intuitive operation experience; 6. The present invention is carefully conceived and provided with a delay detection mechanism, which is a special design for evaluating the performance of the delay spring. Its core purpose is to ensure that the entire delay mechanism system can operate continuously and stably, thus meeting the application requirements of high precision and long life. The delay detection mechanism is cleverly divided into two key parts: one part is responsible for recording and displaying the preset standard delay time before use, which is equivalent to a reference benchmark, providing a clear standard for subsequent performance evaluation; the other part focuses on capturing and recording the actual delay time after use in real time. It is like an accurate timer, accurately reflecting the performance of the delay spring in actual work. By comparing the time data displayed by these two parts, operators can quickly and intuitively evaluate whether the delay performance of the delay spring meets the expectations and whether there are signs of performance decline. This design enables an immediate and effective performance detection after each operation, thus timely discovering and solving potential performance problems, effectively avoiding system errors or operation mistakes caused by the performance degradation of the delay spring, and further ensuring the stability and reliability of the overall system. In addition, this innovative design also greatly improves the maintenance efficiency and convenience of the system. Operators can easily obtain the performance status of the delay spring without disassembling the system or conducting complex tests, and thus make timely decisions on maintenance or replacement, ensuring that the system is always in the best working state. Generally speaking, this delay detection mechanism not only significantly enhances the reliability and stability of the system, but also brings a more efficient and intuitive operation and maintenance experience to operators; 7. The innovative design of the replacement mechanism in the present invention ingeniously overcomes the challenge of rapid replacement when the performance of the delay spring changes, greatly improving the efficiency of maintenance operations. In particular, this design adopts a dual-delay spring configuration. Once the performance of one set of delay springs deteriorates, it can be immediately replaced manually, ensuring that the device can quickly connect and resume operation, maintaining a normal working state. This design effectively reduces the system suspension time caused by part replacement, thus achieving excellent usage effects and outstanding performance. 8. The present invention incorporates a precisely designed leveling mechanism. Its core function is that when the performance of the first set of delay springs changes, this mechanism can accurately adjust the heights of the upper vertical section and the lower vertical section, and then synchronously adjust the position heights of the first set of connecting columns and the two sets of docking slots. This adjustment mechanism not only ensures that the first set of connecting columns can be smoothly separated from the original structure, but also guarantees that the adjusted docking slots can perfectly match the heights of the second set of connecting columns. This ingenious design greatly facilitates the smooth engagement of the second elastic fasteners on the second set of connecting columns with the corresponding card holes, achieving efficient and stable connection operations. In addition, it also facilitates the convenient separation of the second elastic fasteners on the first set of connecting columns from the card holes, thus significantly improving the overall usage efficiency and operation convenience.

Detailed implementation mode

[0017] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all changes, modifications and equivalents that fall within the spirit and scope of the appended claims.

[0018] A switch device with a delay function according to an embodiment of the present invention will be described below with reference to the drawings.

[0019] As Figures 1 - 6 shown, a switch device with a delay function according to an embodiment of the present invention includes: Double - layer hollow box body 1: fixedly arranged on the wall, with an opening - closing switch 11 on its surface and access terminal seats 12 connected to wires symmetrically arranged on its inner wall; Lifting frame 2: Vertically and slidably connected to the inner wall of the double-layer hollow box body 1. The lifting frame 2 includes a vertical section 21. The top of the vertical section 21 is connected to the opening and closing switch 11. An extension spring 23 is sleeved outside the upper end of the vertical section 21. Both ends of the extension spring 23 are fixedly connected to the upper end surface of the vertical section 21 and the inner wall of the double-layer hollow box body 1 respectively. A piston 24 is arranged on the middle end surface of the vertical section 21. The surface of the piston 24 is evenly and slidably connected with an expanding slider 25. One end of the expanding slider 25 penetrates into the inside of the piston 24, and a first spring 251 is arranged between the expanding slider 25 and the inner wall of the piston 24. The lower end surface of the vertical section 21 is fixedly connected with a special-shaped section 22. A conductive column 26 is arranged at the bottom of the special-shaped section 22 and is slidably connected to the inner wall of the access terminal block 12. Double-layer hollow cylinder 3: Fixedly connected to the inner wall of the double-layer hollow box body 1 and sleeved outside the vertical section 21 corresponding to the position of the piston 24. A funnel part 31 communicating with the inside of the double-layer hollow cylinder 3 is arranged at its top, and a damping ring is arranged at the connection with the vertical section 21. Its inside is filled with silicone oil 32 through an oil injection port.

[0020] It should be noted that the inside of the double-layer hollow box body 1 and the double-layer hollow cylinder 3 described in this embodiment have both been precisely vacuumized. This process effectively reduces the interference of the external environment on the internal extension spring 23 and silicone oil 32, ensures the long-term stability of the performance of the extension spring 23 and silicone oil 32, and thus significantly improves the use effect.

[0021] It should also be noted that an oil injection port (not shown in the figure) is also arranged on the surface of the double-layer hollow box body 1 described in this embodiment and is connected to the oil injection port on the surface of the double-layer hollow cylinder 3. A fluid one-way valve (not shown in the figure) is arranged on the inner wall of the oil injection port, which is convenient for the injection needle to enter and effectively prevents the fluid from overflowing after the needle is pulled out.

[0022] It should also be noted that a sealing ring (not shown in the figure) is also arranged at the connection between the funnel part 31 and the vertical section 21 to ensure the sealing performance.

[0023] It should also be noted that the damping ring described in this embodiment is not shown in the figure.

[0024] Specifically, the structure of the present invention is compact and exquisitely designed, which is convenient for installation and maintenance. It adopts a mechanical time-delay structure, which is more stable and reliable than the traditional time relay, has a low failure rate, can meet different time-delay requirements, and can control the time delay by simply adjusting the angle of the knob 111, with convenient operation. At the same time, the innovative design of the expanding slider 25 allows users to finely adjust the time delay, enhancing the flexibility and applicability of the device.

[0025] The double-layer hollow box body 1 is fixedly installed on the wall, and an opening and closing switch 11 is arranged on its exterior for manually controlling the initial state of the switch. Symmetric access end seats 12 are configured on the inner wall of the double-layer hollow box body 1 for electrically connecting with wires to achieve the connection and disconnection of the circuit. The lifting frame 2 is vertically slidably connected to the inner wall of the double-layer hollow box body 1 and is the key component for the device to achieve the delay function. The lifting frame 2 includes a vertical section 21. The top of the vertical section 21 is connected to the opening and closing switch 11 to achieve the physical transmission of the switch state. A delay spring 23 is installed on the outer side of the upper end of the vertical section 21. Both ends of the delay spring 23 are fixedly connected to the vertical section 21 and the inner wall of the double-layer hollow box body 1 respectively, for providing the elastic force required for the lifting frame 2 to reset. A piston 24 is arranged in the middle of the vertical section 21. The surface of the piston 24 is evenly distributed with diameter-expanding sliders 25. One end of the diameter-expanding slider 25 penetrates the inner wall of the piston 24, and a first spring 251 is arranged between the diameter-expanding slider 25 and the inner wall of the piston 24. By adjusting the elastic force of the first spring 251, the extending area of the diameter-expanding slider 25 can also be adjusted, thereby changing the resistance during the lifting process. The lower end of the vertical section 21 is connected to a special-shaped section 22. A conductive column 26 is arranged at the bottom of the special-shaped section 22. The conductive column 26 can slide in the inner wall of the access end seat 12 to achieve the connection and disconnection of the circuit. The double-layer hollow cylinder 3 is fixedly connected to the inner wall of the double-layer hollow box body 1 and is sleeved outside the corresponding vertical section 21 of the piston 24. A funnel part 31 communicating with the inside of the double-layer hollow cylinder 3 is arranged at its top, and a damping ring is arranged at the connection with the vertical section 21. By adjusting the number of damping rings, the lifting speed of the vertical section 21 can be changed. The double-layer hollow cylinder 3 is filled with silicone oil 32. By changing the total amount of the silicone oil 32, the lifting speeds of the piston 24 and the lifting frame 2 can be synchronously changed, thereby prolonging the closing time of the switch.

[0026] During use, when the opening and closing switch 11 is operated, the lifting frame 2 starts to move up and down under the action of the delay spring 23. The damping effects of the silicone oil 32 and the damping ring slow down the movement speed of the lifting frame 2, thereby achieving the delay effect. The extending area of the diameter-expanding slider 25 adjusts the resistance during the lifting process, and then finely adjusts the delay time. When the lifting frame 2 descends to the lowest point, the conductive column 26 contacts the access end seat 12, and the circuit is connected. When the lifting frame 2 resets under the action of the delay spring 23, the conductive column 26 separates from the access end seat 12, and the circuit is disconnected.

[0027] In an embodiment of the present invention, as Figure 2As shown, the opening and closing switch 11 includes a knob 111, a first lead screw 112, a translation slider 113, and a first conical part 114. Among them, the knob 111 is rotatably connected to the surface of the double-layer hollow box body 1, the first lead screw 112 is rotatably connected to the inner wall of the double-layer hollow box body 1 and is connected to the knob 111. The translation slider 113 is threadedly connected to the outer surface of the first lead screw 112 and is horizontally slidably connected to the inner wall of the double-layer hollow box body 1. The first conical part 114 is integrally formed at the bottom of the translation slider 113 and is slidably connected to the inner wall of the first conical groove 211 opened at the top of the vertical section 21.

[0028] It should be noted that a first annular scale line is provided at the position corresponding to the outer side of the knob 111 on the surface of the double-layer hollow box body 1 described in this embodiment.

[0029] Specifically, further illustrate the structure and connection relationship of the opening and closing switch 11. The structure of the opening and closing switch 11 is reasonable, aiming to achieve the functions of quick connection and delayed closing of the switch. During operation, the user only needs to rotate the knob 111, and this action will drive the first lead screw 112 to rotate synchronously. The rotation of the first lead screw 112 further drives the translation slider 113 to slide smoothly to one side. As the translation slider 113 moves, the first conical part 114 installed on it also moves accordingly, and gradually presses the first conical groove 211 located at the top of the vertical section 21 during this process. This pressing action not only causes the first conical groove 211 to be stressed, but also drives the entire vertical section 21 to move downward. The precise cooperation between the first lead screw 112 and the translation slider 113 ensures the position accuracy and stability during the operation process. By flexibly adjusting the position of the translation slider 113, the user can conveniently and accurately control the descending distance of the vertical section 21, which actually adjusts the compression degree of the delay spring 23. The change in the compression amount is directly related to the adjustment of the delay time, making the operation simple and efficient with good use effects.

[0030] In an embodiment of the present invention, as Figures 2 - 4 shown, a tooth column 41 is rotatably connected to the surface of the special-shaped section 22. The center of the top of the tooth column 41 is fixedly connected to a second lead screw 42 and is located inside the vertical section 21. A threaded sleeve 43 is vertically slidably connected to the inner wall of the vertical section 21 and is threadedly connected to the outer surface of the second lead screw 42. The top of the threaded sleeve 43 is uniformly integrally formed with a second conical part 44. A second conical groove 252 is opened at the position corresponding to the second conical part 44 on the surface of the end of the expansion slider 25 that penetrates into the piston 24. The second conical part 44 is located inside the second conical groove 252 and is slidably connected to the inner wall of the second conical groove 252.

[0031] It should be noted that the tooth column 41, the second lead screw 42, the threaded sleeve 43, and the second conical part 44 described in this embodiment cooperate to form a variable diameter adjustment mechanism 4.

[0032] Specifically, the variable-diameter adjusting mechanism 4 is ingeniously designed to quickly adjust the position (extended area or volume) of the diameter-expanding slider 25. By precisely controlling the position of the diameter-expanding slider 25, the resistance during the lifting process is changed, thereby achieving diverse delay effects, and its application effect is extremely excellent.

[0033] In actual operation, the rotation of the tooth column 41 will seamlessly drive the second lead screw 42 to rotate synchronously. This rotation action immediately causes the threaded sleeve 43 to smoothly rise or fall along the second lead screw 42. As the threaded sleeve 43 moves up and down, the second tapered portion 44 thereon also rises and falls. During this process, the extrusion force generated by the second tapered portion 44 on the second tapered groove 252 in the diameter-expanding slider 25 will change. Under the action of the elastic force of the first spring 251, the diameter-expanding slider 25 will automatically adjust its position according to the change in the extrusion force, thereby changing the magnitude of the provided resistance. The increase or decrease of the resistance directly determines the difference in the delay effect, enabling the mechanism to flexibly adapt to different time-effect requirements, with simple operation and remarkable effects.

[0034] In an embodiment of the present invention, as Figures 2 - 3 shown, an externally adjustable gear 45 is rotatably connected to the inner wall of the double-layer hollow box body 1. The surface of one end of the externally adjustable gear 45 located inside the double-layer hollow box body 1 is provided with teeth and meshes with the tooth column 41. The surface of the other end of the externally adjustable gear 45 located outside the double-layer hollow box body 1 is provided with a scale index.

[0035] Specifically, the externally adjustable gear 45 is provided to facilitate direct operation from the outside of the double-layer hollow box body 1 to drive the internal tooth column 41 to rotate. Among them, the two ends of the externally adjustable gear 45 are extremely exquisitely designed. The inner end is equipped with teeth to ensure precise meshing with the tooth column 41 and achieve smooth driving, while the outer end is attached with a clear scale index. This user-friendly design enables the operator to quickly and intuitively read and adjust the required parameters, greatly improving the convenience and effect of use.

[0036] In an embodiment of the present invention, as Figure 3As shown, a synchronous gear 51, a first speed-changing gear 52, and a second speed-changing gear 53 are sequentially and rotatably connected to the inner wall of the double-layer hollow box body 1 and are meshed with each other. One end of the central axis of the synchronous gear 51 is fixedly connected to the bottom of the tooth column 41. A first bevel gear 54 is fixedly connected to the surface of the second speed-changing gear 53. A second bevel gear 55 is rotatably connected to the inner wall of the double-layer hollow box body 1 and is meshed with the first bevel gear 54. One end of the second bevel gear 55 penetrates outside the double-layer hollow box body 1 and is fixedly connected to a first pointer 56. A second pointer 57 is rotatably connected to the inner wall of the first pointer 56. One end of the second pointer 57 away from the first pointer 56 penetrates outside the second bevel gear 55 and is fixedly connected to a detection gear 58. The detection gear 58 is located inside the double-layer hollow box body 1. A detection tooth bar 59 is vertically slidably connected to one side of the detection gear 58 and is meshed with it. One end of the detection tooth bar 59 away from the detection gear 58 is sleeved outside the vertical section 21 and is fixedly connected to the surface of the vertical section 21.

[0037] It should be noted that in this embodiment, the synchronous gear 51, the first speed-changing gear 52, the second speed-changing gear 53, the first bevel gear 54, the second bevel gear 55, the first pointer 56, the second pointer 57, the detection gear 58, and the detection tooth bar 59 cooperate to form a delay detection mechanism 5.

[0038] It should be noted that a second circular scale line is provided on the surface of the double-layer hollow box body 1 described in this embodiment, and the second circular scale line is located outside the first pointer 56 and the second pointer 57.

[0039] Specifically, the delay detection mechanism 5 is specifically designed to evaluate the performance of the delay spring 23, so as to accurately judge whether it needs to be replaced to ensure the stable performance of the overall system. During the operation, the rotation of the tooth column 41 will synchronously drive the synchronous gear 51, the first speed-changing gear 52, the second speed-changing gear 53, and the first bevel gear 54 to rotate. The rotation of the first bevel gear 54 will further drive the second bevel gear 55 and the first pointer 56 to rotate synchronously. The data pointed by the needle of the first pointer 56 represents the standard delay time data. At the same time, the rising of the vertical section 21 will synchronously drive the detection tooth bar 59 to rise, and the rising of the detection tooth bar 59 will further drive the detection gear 58 and the second pointer 57 to rotate. The data pointed by the needle of the second pointer 57 reflects the actual delay time data. By comparing these two time data, we can accurately judge the accuracy of the delay data. If the data is accurate, the delay spring 23 can continue to be used. If the data is inaccurate, the delay spring 23 should be replaced in time to ensure the stability and reliability of the system. This detection method is not only efficient but also highly practical.

[0040] In an embodiment of the present invention, as Figure 5As shown, a sliding frame 61 is slidably connected to the inner wall of the right-side groove on the surface of the double-layer hollow box body 1. One end of the sliding frame 61 penetrates into the double-layer hollow box body 1, and installation grooves 63 are symmetrically arranged. On the surface of the end of the sliding frame 61 that penetrates into the double-layer hollow box body 1, first elastic clamping members 62 are symmetrically arranged and are clamped and fixed to the inner wall of the double-layer hollow box body 1. A connecting column 64 is vertically slidably connected to the inner wall of the installation groove 63. A delay spring 23 is sleeved outside the connecting column 64, and its two ends are respectively fixedly connected to the surface of the connecting column 64 and the inner wall of the installation groove 63. Both ends of the connecting column 64 respectively penetrate outside the sliding frame 61 and are fixedly connected with second elastic clamping members 65; The vertical section 21 includes an upper vertical section 210 and a lower vertical section 220. A first tapered groove 211 is opened at the top of the upper vertical section 210. A piston 24 is arranged on the surface of the lower vertical section 220. Docking grooves 212 are respectively opened at the positions corresponding to the bottom of the upper vertical section 210 and the top of the lower vertical section 220. Both ends of the connecting column 64 are respectively located in the two groups of docking grooves 212. Card holes are respectively opened on the inner walls of the two groups of docking grooves 212 and are clamped and fixed with the second elastic clamping members 65.

[0041] It should be noted that the sliding frame 61, the first elastic clamping member 62, the installation groove 63, the connecting column 64 and the second elastic clamping member 65 described in this embodiment cooperate to form a replacement mechanism 6.

[0042] It should be noted that the number of the first elastic clamping members 62 described in this embodiment is two groups.

[0043] Specifically, the design of the replacement mechanism 6 cleverly solves the problem of quickly replacing the delay spring 23 when its performance changes, greatly improving the work efficiency. The specific operation process is as follows. When the delay spring 23 needs to be replaced, the user only needs to gently push the sliding frame 61 inward. As the sliding frame 61 moves, it will synchronously drive the first elastic clamping member 62 thereon to move. In this process, the first group of first elastic clamping members 62 that were originally clamped and fixed to the card holes on the inner wall of the double-layer hollow box body 1 will gradually separate from the card holes. At the same time, the second elastic clamping members 65 on the first group of connecting columns 64 will also disengage from the card holes in the docking grooves 212, completing the unlocking of the current delay spring 23. As the sliding frame 61 continues to move, the second group of first elastic clamping members 62 will gradually approach and finally be clamped and fixed to the card holes on the inner wall of the double-layer hollow box body 1. At the same time, the second elastic clamping members 65 on the second group of connecting columns 64 will also move into the docking grooves 212 and be clamped and fixed to the card holes therein, thus realizing the fixation and switching of the new delay spring 23. This design not only makes the replacement of the delay spring 23 fast and simple, but also ensures the stability and accuracy during the replacement process. The high efficiency and practicality of the replacement mechanism 6 undoubtedly provide a strong guarantee for the stable operation of the entire system, and the use effect is good.

[0044] In an embodiment of the present invention, asFigure 6 As shown in the figure, guide shafts 71 are symmetrically and horizontally slidably connected to the inner walls of the left slots on the surface of the double-layer hollow box body 1. One end of each guide shaft 71 is fixedly connected to a plate member 72, and a third spring 73 is fixedly connected between the guide shaft 71 and the inner wall of the left slot. The other end of the guide shaft 71 penetrates into the double-layer hollow box body 1 and is fixedly connected to a tapered block 74. Third tapered grooves 75 are respectively formed at positions corresponding to the tapered block 74 on the surfaces of the upper vertical section 210 and the lower vertical section 220. The tapered block 74 is slidably connected to the inner wall of the third tapered groove 75.

[0045] It should be noted that in this embodiment, the guide shafts 71, the plate members 72, the third springs 73, the tapered blocks 74 and the third tapered grooves 75 cooperate to form a leveling mechanism 7.

[0046] It can be understood that when the performance of the delay springs 23 in the first set of mounting grooves 63 changes, resulting in corresponding adjustments to the heights of their upper vertical sections 210 and lower vertical sections 220, since the height of the subsequent connecting columns 64 is fixed, in order to ensure smooth installation, we need to flexibly adjust the positions of the docking grooves 212 on the upper vertical section 210 and the lower vertical section 220 to match the fixed height of the next set of connecting columns 64. Such a design allows us to quickly and accurately replace the delay springs 23 by simply adjusting the height of the docking grooves 212 without replacing the entire mechanism, greatly improving the operation convenience and system adaptability.

[0047] Specifically, the leveling mechanism 7 is carefully designed to adjust the heights of the two sets of docking grooves 212 to ensure that they match the height of the second set of connecting columns 64, so that the second elastic clamping members 65 on the second set of connecting columns 64 can be smoothly clamped with the card holes, realizing fast and stable connection, greatly improving the use efficiency and convenience. In actual operation, the user only needs to gently push the plate member 72 inward. As the plate member 72 moves, it will synchronously drive the guide shafts 71 and the tapered blocks 74 to move together, and compress the third spring 73 to store energy during this process. When the tapered block 74 enters the third tapered groove 75, it will use its tapered structure to apply pressure to the groove wall, thereby synchronously adjusting the heights of the two sets of docking grooves 212 and the first set of connecting columns 64. This adjustment process ensures that the height of the first set of connecting columns 64 can be perfectly adapted to the height of the second set of connecting columns 64, providing great convenience for subsequent switching and connection use. The ingenious design and efficient function of the leveling mechanism 7 undoubtedly provide strong support for the stable operation and flexible switching of the entire system.

[0048] In summary, a switch device with a time-delay function according to an embodiment of the present invention has a compact and ingenious structure, which is convenient for installation and maintenance. The mechanical time-delay structure is adopted, which is more stable and reliable than traditional time relays, with a low failure rate, and can meet different time-delay requirements. By simply adjusting the angle of the knob 111, the time delay can be controlled, and the operation is convenient. At the same time, the innovative design of the enlarged-diameter slider 25 allows users to finely adjust the time delay, enhancing the flexibility and applicability of the device.
