Description

Technical Field

[0001] This utility model belongs to the field of timers, and specifically relates to a convenient adjustment mechanism for micro switches. Background Technology

[0002] After a period of cooling operation, some refrigeration equipment, such as air conditioners and refrigerators, will have a layer of frost condense on the surface of their refrigeration units. This will seriously affect the cooling efficiency of the refrigeration equipment. Therefore, most of these refrigeration equipment are equipped with a defrosting section, which requires a timer to control the heater to perform the defrosting process.

[0003] However, most existing mechanical timers currently use gear assemblies to drive a turntable to rotate. During the rotation of the turntable, the first and second actuating components abut against the lever, which in turn drives the lever to contact or disconnect the contact switch, thus achieving the effect of a timed switch. Therefore, traditional mechanical timers set the running time by rotating the dial. When the time reaches the preset value, the internal mechanical mechanism triggers the switch action, which limits the control accuracy and response speed of this structure and is not conducive to controlling external devices. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a simple, fast-responding, and convenient adjustment mechanism and timer for microswitches that improves control stability and reliability.

[0005] The objective of this utility model can be achieved by addressing the following technical problem: a convenient adjustment mechanism for micro switches is proposed, comprising a base, a shaped piece, and a micro switch, wherein:

[0006] The irregularly shaped piece is movably mounted on the base, and a protrusion is formed at the edge of the irregularly shaped piece. The two sides of the protrusion and the irregularly shaped piece respectively form a first limiting part and a second limiting part.

[0007] The micro switch is mounted on the base and is used to connect to external devices. The micro switch has a roller and a conductive plate. The roller is movably pressed against the first limiting part and can be moved into the second limiting part by the rotation of the irregular piece across the protrusion. The conductive plate can move relative to the micro switch as the roller rotates to switch the micro switch and realize the control of the external device.

[0008] In the aforementioned convenient adjustment mechanism applied to a micro switch, the micro switch further includes:

[0009] A fixed frame is mounted on the base.

[0010] A micro switch body is disposed within the fixed frame. A connecting block is formed on the side of the micro switch body near the irregularly shaped piece. A mounting base is disposed on the connecting block. The conductive piece is connected to the mounting base and extends toward the micro switch body. The roller is movably disposed within the mounting base.

[0011] In the aforementioned convenient adjustment mechanism applied to a micro switch, the irregularly shaped piece is further provided with a toggle part.

[0012] In the aforementioned convenient adjustment mechanism for microswitches, the end of the connecting block is formed with an arc-shaped surface, and the mounting base is tangentially connected to the arc-shaped surface.

[0013] In the aforementioned convenient adjustment mechanism for a micro switch, the fixed frame includes a bottom plate and a top plate arranged in parallel, a receiving plate connecting the bottom plate and the top plate, and the bottom plate, the top plate and the receiving plate together enclose a semi-enclosed cavity, in which the micro switch body is placed.

[0014] In the aforementioned convenient adjustment mechanism for a micro switch, both the base plate and the top plate have through holes, and fasteners are connected inside the through holes. The fasteners penetrate the micro switch body to restrict the micro switch body onto the base.

[0015] In the aforementioned convenient adjustment mechanism for micro switches, an anti-loosening washer is also provided on the top plate, and the top end of the fastener is movably pressed against the anti-loosening washer.

[0016] In the aforementioned convenient adjustment mechanism for micro switches, a flange is also formed on the base plate, which is parallel to the flange. An avoidance hole is provided on the flange, and the avoidance hole is coaxially arranged with the through hole and connected to it.

[0017] In the aforementioned convenient adjustment mechanism applied to a micro switch, a wire harness connects the micro switch to the external device.

[0018] The technical solution adopted by this utility model to solve its technical problem is to also propose a timer, including one of the above-mentioned convenient adjustment mechanisms applied to micro switches.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) This utility model provides a convenient adjustment mechanism and timer for micro switches. By adding a micro switch to the timer, the roller can be switched between different limit positions by rotating the irregular piece. Thus, the external device can be effectively controlled during the switching process of the micro switch. The overall structure is simple, the response is fast, the control is precise, and the overall stability and reliability of the timer are improved.

[0021] (2) The semi-enclosed cavity provides a stable installation space for the micro switch body, which enhances the rigidity and anti-interference ability of the overall structure. This design effectively prevents the influence of external vibration or impact on the micro switch, improves the operation stability and safety of the regulating mechanism, and is suitable for complex working environments.

[0022] (3) The anti-loosening gasket can effectively prevent the fasteners from loosening due to vibration or external force, further enhancing the installation stability of the micro switch body, extending the service life of the equipment, and the overall structure is simple and reliable, improving the vibration resistance and overall safety of the adjustment mechanism.

Detailed Implementation

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0030] like Figure 1 As shown, this solution mainly describes a convenient adjustment mechanism for a micro switch 3 used in a timer. However, this convenient adjustment mechanism for a micro switch 3 is not limited to use in a timer, but can also be applied to other devices that require timing control.

[0031] like Figures 1 to 4 As shown, a convenient adjustment mechanism for a micro switch 3 includes a base 1, a shaped piece 2, and a micro switch 3.

[0032] The irregularly shaped piece 2 is movably mounted on the base 1. A protrusion 20 is formed at the edge of the irregularly shaped piece 2. The two sides of the protrusion 20 together with the irregularly shaped piece 2 form a first limiting part 200 and a second limiting part 201, respectively. The micro switch 3 is mounted on the base 1 and is used to connect external devices. The micro switch 3 has a roller 30 and a conductive piece 31. The roller 30 is movably pressed against the first limiting part 200 and can be movably locked into the second limiting part 201 as the irregularly shaped piece 2 rotates across the protrusion 20. The conductive piece 31 can move relative to the micro switch 3 as the roller 30 rotates, so as to switch the micro switch 3 to realize the control of external devices.

[0033] like Figures 1 to 4 As shown, in this embodiment, the irregularly shaped piece 2 can rotate synchronously with the timer dial. It is worth noting that the structure and working principle of the timer used in this embodiment are the same as those of the prior art, and will not be described in detail here. At this time, the first limiting part 200 at the edge of the irregularly shaped piece 2 stably accommodates and abuts against the roller 30 of the micro switch 3. As the irregularly shaped piece 2 moves along the roller dial, the roller rotates synchronously with the timer dial. Figure 1As the roller 30 rotates clockwise and passes over the protrusion 20, it experiences continuous pressure from the irregularly shaped piece 2. This pressure is transmitted through the roller 30 to the micro switch 3, which in turn switches via the conductive piece 31 (equivalent to a switch). This continues until the roller 30 fully enters the second limiting part 201. At this point, the direction and force of the roller 30's action on the micro switch 3 change, thus switching the state of the micro switch 3. Therefore, this structure, by adding a micro switch 3 to the timer, allows the rotation of the timer dial to control the switching of the micro switch 3 via the irregularly shaped piece 2, ultimately achieving precise control of external devices. The overall structure is ingeniously and compactly designed, easy to operate, and with the limiting parts at two different positions working in conjunction with the roller 30 and the conductive piece 31, the conductive piece 31 moves with the roller 30 to turn the micro switch 3 on or off. It offers rapid response, precise control, and is easy to integrate into miniaturized devices. It is also suitable for automated control systems with high real-time control requirements.

[0034] The micro switch 3 also includes: a fixed frame 32, which is mounted on the base 1; a micro switch body 33, which is mounted inside the fixed frame 32, and a connecting block 330 is formed on the side of the micro switch body 33 near the irregular piece 2. A mounting base 331 is provided on the connecting block 330, and the conductive piece 31 is connected to the mounting base 331 and extends toward the micro switch body 33; and a roller 30 is movably mounted inside the mounting base 331.

[0035] like Figures 1 to 3 As shown, in this embodiment, a fixed frame 32 is used to fix the micro switch body 33 as a whole, which improves the installation stability and vibration resistance. By setting an integrated mounting base 331 on the connecting block 330, the roller 30 and the conductive piece 31 are arranged in a concentrated manner, which simplifies the transmission structure, reduces the number of parts and assembly errors, improves the accuracy of action transmission and the overall reliability of the mechanism, and is conducive to achieving long-term stable operation.

[0036] The end of the connecting block 330 has an arc-shaped surface 330a, and the mounting base 331 is tangentially connected to the arc-shaped surface 330a.

[0037] like Figure 3 As shown, in this embodiment, the arc-shaped surface 330a is tangentially connected to the mounting base 331. This makes the contact transition between the roller 30 and the limiting part smoother as the roller 30 crosses the protrusion 20, reducing movement resistance and impact force, effectively preventing jamming or jumping, improving the smoothness and stability of the switching process, and extending service life. Therefore, this structure helps to make the entire triggering process smoother and reduces mechanical shock and vibration, which helps to ensure that the action process of each trigger and reset is highly consistent, improving the repeatability accuracy of the switching action.

[0038] The fixed frame 32 includes a bottom plate 320 and a top plate 321 arranged in parallel. A support plate 323 is connected between the bottom plate 320 and the top plate 321. The bottom plate 320, the top plate 321 and the support plate 323 together form a semi-enclosed cavity 324. The micro switch body 33 is placed in the semi-enclosed cavity 324.

[0039] like Figure 4 As shown, in this embodiment, the micro switch body 33 is securely embedded in the semi-enclosed cavity 324 of the fixed frame 32. The bottom plate 320 provides bottom support, the top plate 321 provides top limiting (to prevent the micro switch body 33 from jumping upward), and the receiving plate 323 provides lateral (usually rear and / or one side) positioning and limiting. Therefore, the semi-enclosed cavity 324 structure can not only firmly fix the micro switch body 33, but also facilitate installation, disassembly and maintenance. The three-dimensional support structure formed by the bottom plate 320, the top plate 321 and the receiving plate 323 enhances the overall rigidity, effectively preventing the micro switch 3 from shifting or loosening during operation, and improving the safety and stability of equipment operation.

[0040] Both the base plate 320 and the top plate 321 have through holes 322a. Fasteners 322b are connected inside the through holes 322a. The fasteners 322b pass through the micro switch body 33 to restrict the micro switch body 33 to the base 1.

[0041] like Figure 4 As shown, in this embodiment, the micro switch body 33 is clamped and fixed in the vertical direction by means of the upper and lower through holes 322a and the fasteners 322b passing through it. During the assembly process, as the micro switch body 33 is pushed in from the opening end of the semi-enclosed cavity 324, the fasteners 322b (such as screws, bolts, etc.) can be inserted from the through holes 322a on the top plate 321 side, so that they pass through the through holes 322a of the top plate 321, the micro switch body 33 and the bottom plate 320. The overall fastening force is evenly distributed, and the fixation is firm and reliable, effectively avoiding loosening caused by vibration or external force, and ensuring the positional consistency and reliability of the micro switch 3 under frequent operation.

[0042] The top plate 321 is also provided with an anti-loosening washer 321a, and the top of the fastener 322b is movably pressed onto the anti-loosening washer 321a.

[0043] like Figure 3 As shown, the anti-loosening washer 321a in this embodiment can effectively absorb vibration energy. At the same time, the anti-loosening washer 321a continuously provides anti-loosening protection throughout its service life, ensuring that the fastener 322b will not loosen on its own due to fatigue or vibration, which significantly improves the reliability and durability of the connection and reduces the maintenance frequency.

[0044] A flange 320a is also formed on the base plate 320, which is parallel to it. A clearance hole 320b is provided on the flange 320a. The clearance hole 320b is coaxially arranged with the through hole 322a and is connected to it.

[0045] like Figure 4 As shown, the flange 320a structure enhances the overall strength of the base plate 320, preventing deformation or cracking around the through hole 322a due to the fastener 322b tightening. When the micro switch 3 is subjected to lateral force or torque, the flange 320a can effectively resist deformation, thereby maintaining the stability of the entire structure. In addition, by relying on the clearance hole 320b and the through hole 322a being coaxial and interconnected, the fastener 322b can pass smoothly and provide sufficient assembly space, ensuring that the fastener 322b (such as screws, bolts, etc.) can be tightened more, providing a larger and more precisely controllable preload (controlled by torque), resulting in high connection strength and easy disassembly and maintenance. At the same time, this structure helps guide the installation direction, improving assembly efficiency and accuracy.

[0046] Preferably, such as Figure 1 and Figure 2 As shown, in this embodiment, a toggle part 21 is added to the irregularly shaped piece 2, which makes it easy for the user to directly apply force with their fingers or tools to rotate it, improving the convenience and accuracy of human-computer interaction, avoiding slippage or misoperation due to the small contact surface, and further enhancing the convenience and safety of adjustment.

[0047] like Figure 1 and Figure 3 As shown, in this embodiment, a wiring harness 332 is also connected between the micro switch 3 and the external device. The wiring harness 332 realizes the electrical connection between the micro switch 3 and the external device. The wiring is neat, the insulation is good, and it is easy to inspect and replace, which improves the safety and maintainability of the system, while adapting to the flexible wiring needs of different installation environments.
