Description

Technical Field

[0001] This utility model relates to the field of timer switch technology, specifically to a flip-top structure for a timer switch. Background Technology

[0002] As an electrical control element that can automatically control the on and off of a circuit according to a preset time, timer switches are widely used in various scenarios such as homes, industrial production, and commercial venues due to their convenient time control function. For example, they can control the automatic start and stop of lighting fixtures, the timed operation of household appliances, and the intermittent operation of industrial equipment, greatly improving the convenience of using electrical equipment and the energy efficiency of energy utilization.

[0003] In the structural design of timer switches, to protect core components such as internal terminals and adjustment knobs from dust, moisture, and foreign objects that could cause circuit malfunctions, and to prevent accidental contact with live parts that could lead to safety hazards, a flip-top structure is typically installed on the switch housing. This openable and closable cover provides shielding and protection for critical areas. As a crucial component of timer switches, the ease of opening and closing, stability after opening, and structural reliability of the flip-top structure directly affect the overall user experience and protective effectiveness of the timer switch.

[0004] Most existing timer switch flip-top structures employ a simple rotary hinge mechanism, where the cover is hinged to the outer shell via a rotating shaft to achieve opening and closing. However, this traditional flip-top structure has significant shortcomings in practical use: when wiring, adjusting time parameters, or performing maintenance on the timer switch, the cover needs to be opened and held at a specific angle to allow operators to perform hand operations. However, traditional structures lack effective positioning and limiting mechanisms, and the cover can easily close itself under its own weight or slight external contact after opening, interfering with the operator's workflow and reducing operational efficiency.

[0005] Based on the shortcomings of the existing technology, there is an urgent need for a timed switch flip cover structure that is simple in structure, convenient to open and close, and stable in positioning after opening, in order to solve the problems of traditional flip cover structures such as easy self-closing, poor positioning reliability, and inconvenient operation. Utility Model Content

[0006] To address the shortcomings in the prior art, this utility model provides a flip cover structure with a timed switch.

[0007] The technical solution adopted by this utility model is: a flip-top structure for a timer switch, comprising a shell and a cover. The outer shell has rotating protrusions on both sides at one end and a connecting buckle plate on the other side. The connecting buckle plate has a fastening groove. The raised step between the rotating protrusions has an arc-shaped concave surface, and the rotating protrusion has a rotating hole. One end of the cover is provided with a connecting part, and the other end is provided with a fastening protrusion that connects with the fastening groove. Both ends of the connecting part are provided with a rotating shaft that rotatably engages with the rotating hole, and one side of the connecting part is provided with an arc-shaped protrusion that matches the arc-shaped concave surface. When the cover is rotated relative to the outer shell to the open state, the arc-shaped protrusion engages with the arc-shaped concave surface to keep the cover open.

[0008] Furthermore, the two sides of the arc-shaped concave surface are provided with gently sloping arc surfaces.

[0009] Furthermore, an inlet ramp is provided at the upper end of the rotating hole.

[0010] Furthermore, a fitting groove is provided on one side of the protruding step, and a cover protrusion adapted to the fitting groove is provided on the cover below the connecting part.

[0011] Furthermore, the upper end of the connecting buckle plate is provided with a rounded corner.

[0012] Furthermore, a pressing plate is connected to one side of the fastening slot via a connecting strip.

[0013] Furthermore, one side of the pressing plate is provided with a pressing protrusion, and the other side is provided with an action protrusion corresponding to the arc-shaped protrusion.

[0014] The beneficial effects of this utility model are: 1. Achieve stable positioning after the cover is opened, improving operational convenience: This structure features an arc-shaped concave surface on the raised step between the rotating protrusions of the outer shell, and a corresponding arc-shaped protrusion at the cover connection. When the cover rotates relative to the outer shell to the open state, the arc-shaped protrusion and the arc-shaped concave surface precisely engage, forming a reliable positioning and limiting mechanism. This effectively solves the problem of the cover easily closing itself due to the lack of positioning function in traditional flip-cover structures. It ensures that the cover remains stably at a preset angle after opening, preventing operators from being disturbed by accidental cover closure during wiring, parameter adjustment, or maintenance, thus improving operational convenience.

[0015] 2. Simple and reliable structure, reducing manufacturing costs: The positioning function of this application is achieved solely through the matching structure of the arc-shaped concave surface and the arc-shaped convex part, eliminating the need for complex components such as elastic pads, friction plates, or multi-position buckles, thus simplifying the overall design of the flip cover structure. This not only reduces the difficulty of mold processing and the number of parts and assembly steps, thereby reducing production costs, but also avoids positioning failures caused by wear or fatigue fracture of additional parts, improving the reliability of the structure.

[0016] 3. Smooth and effortless opening and closing: The cover and the outer shell are hinged together by a rotating shaft and a rotating hole. With the interlocking positioning of the arc-shaped protrusion and the arc-shaped concave surface, only a slight force between the arc-shaped surfaces needs to be overcome during the opening and closing process to complete the positioning and unlocking, making the operation smooth and effortless.

[0017] In addition to the objectives, features and advantages described above, this utility model has other objectives, features and advantages.

[0027] 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.

[0028] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0029] This utility model provides a flip-top structure with a timer switch.

[0030] In this embodiment, refer to Figure 1-7 The flip-top structure of the timer switch includes a housing 1 and a cover 2. The outer shell 1 has rotating protrusions 3 on both sides of one end and a connecting buckle plate 4 on the other side. The connecting buckle plate has a fastening groove 5. The raised step 6 between the rotating protrusions has an arc-shaped concave surface 7, and the rotating protrusion 3 has a rotating hole 8. One end of the cover is provided with a connecting part 9, and the other end is provided with a fastening protrusion 10 that connects with the fastening groove. Both ends of the connecting part 9 are provided with a rotating shaft 11 that rotatably engages with the rotating hole. One side of the connecting part is provided with an arc-shaped protrusion 12 that matches the arc-shaped concave surface. When the cover is rotated relative to the outer shell to the open state, the arc-shaped protrusion engages with the arc-shaped concave surface to keep the cover open.

[0031] In the above technical solution, the timed switch flip cover structure achieves its function by constructing a composite connection structure of "rotational hinge + fitting positioning" between the outer shell and the cover. One end of the outer shell has rotating protrusions with rotating holes on both sides, and an arc-shaped concave surface between the protrusions; the other end has a connecting plate with a fastening groove. One end of the cover has a connecting part, with rotating shafts at both ends adapted to the rotating holes, an arc-shaped protrusion on one side adapted to the arc-shaped concave surface, and a fastening protrusion on the other end adapted to the fastening groove. When closed, the fastening protrusion and the fastening groove engage to achieve a seal; when opened, the cover rotates around the axis of the rotating shaft and the rotating hole. When rotated to a preset opening angle, the arc-shaped protrusion and the arc-shaped concave surface precisely engage, forming a mechanical limit and preventing the cover from rotating on its own. This achieves stable flipping of the cover around the rotating shaft, keeps the cover open when opened, and ensures a stable seal when closed, improving the reliability and ease of use of the flip cover structure.

[0032] Specifically, the two sides of the arc-shaped concave surface are provided with gently sloping arc surfaces 13.

[0033] In this embodiment, gently sloping arc surfaces 13 are added to both sides of the arc-shaped concave surface to optimize the interlocking transition path between the arc-shaped concave surface and the arc-shaped convex surface. This reduces the collision and friction between the arc-shaped convex surface and the arc-shaped concave surface when the cap is opened and closed, reduces operating resistance and wear, and improves the opening and closing feel and the service life of the structure.

[0034] Specifically, the upper end of the rotating hole is provided with an inlet inclined surface 14.

[0035] In this embodiment, an inlet ramp 14 is provided at the upper end of the rotating hole to form a guide structure to assist in the assembly of the rotating shaft. During assembly, the rotating shaft can slide into the rotating hole along the inlet ramp, reducing the difficulty of assembly alignment, improving assembly efficiency, and avoiding damage to the shaft hole structure during assembly.

[0036] Specifically, a fitting groove 15 is provided on one side of the protruding step, and a cover protrusion 16 adapted to the fitting groove is provided on the cover below the connecting part.

[0037] In this embodiment, a fitting groove is provided on one side of the raised step, and a matching fitting protrusion is provided below the cap connection part, so that the two fit together when closed. This enhances the structural stability of the cap after it is closed, reduces the gap between the cap and the outer shell, improves dustproof and waterproof performance, and prevents the cap from shaking during use.

[0038] Specifically, the upper end of the connecting buckle plate is provided with a rounded corner 17.

[0039] In this embodiment, a rounded corner is provided at the upper end of the connecting buckle plate to provide a transition and guide function when the cover is closed.

[0040] Specifically, one side of the snap-fit ​​groove is connected to a pressing plate 19 via a connecting strip 18.

[0041] In this embodiment, a pressing plate is connected to one side of the snap-fit ​​groove via a connecting strip, and the device can be unlocked by pressing the pressing plate.

[0042] Specifically, the pressing plate has a pressing protrusion 20 on one side and an action protrusion 21 corresponding to the arc-shaped protrusion on the other side.

[0043] In this embodiment, the pressing protrusion improves the accuracy and feel of pressing and positioning, and the action protrusion can help push the arc-shaped protrusion to disengage, further optimizing the smoothness of opening and ensuring that the unlocking and flipping actions are smooth and efficient.

[0044] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
