  • Patent number: 9434061
    Abstract: The present invention relates to a restart protection device and a method thereof, wherein the restart protection device is installed in an electric device, and comprises a switch module and a restart protecting module. The restart protecting module is connected between the switch module and a motor of the electric device, used for preventing the current outputted by an external electrical power from directly flowing into the motor when the electric device is restarted. To start the electric device, the user must follow the steps of the restart protection method, such that the unexpected accidents resulted from the sudden restart of the electric device can be effectively prevented.

  • Patent number: 8981244
    Abstract: The present invention relates to a forward/backward rotation switching mechanism, comprising: a cover, a turntable, a terminal-fixing body, a first contact terminal, and a second contact terminal. In the present invention, a plurality of dust-off trenches are especially formed on the peripheral edges of the turntable for preventing from the dust accumulation between the turntable and a cover; therefore, even if the forward/backward rotation switching mechanism is used in an environment having a lot of dust, the turntable can still be turned around because the dust is ruled out by the dust-off trenches.

  • Patent number: 8822852
    Abstract: A rotary switch with multi-level is disclosed. The rotary switch includes a rotary base that drives the first conductive sheet to rotate with the second conductive sheet when the rotary shaft is rotated, and the second conductive sheet leaves one of the conductive contact elements; the position end of the second conductive sheet is pressed by one positioning surface during the rotation, and the second spring stores energy; the second spring then releases the energy to the fourth end of the second conductive sheet, and the position end of the second conductive sheet slides on one positioning surface until the position end of the second conductive sheets is positioned solidly between two positioning surfaces; so that, the material cost in production can be lower down, and life time of the rotary switch can be increased.

  • Publication number: 20140131187
    Abstract: Heat-spot distant type push switch structure comprises: a supporting terminal, a compression spring, a switching spring, an electrical terminal, and a sliding lever assembly. Compression spring, switching spring and the switching member of the sliding lever assembly are stacked for connection and facilitate the occupied space of the heat-spot distant type push switch structure capable of being reduced; moreover, the supporting terminal, the compression spring, the switching spring, the electrical terminal, and the sliding lever assembly are designed to particular structures for forming a specific distant between the switching member and the touch point of two contact points of the heat-spot distant type push switch structure, such that the switching member is away from the heat-spot produced by the two contact points; therefore the switching member can still not be fused after the heat-spot distant type push switch structure is long-term used.

  • Publication number: 20130314921
    Abstract: An explosion-proof lamp with a heat dissipation mechanism includes a lamp base, a heat dissipater and a lighting module. The heat dissipater further includes a heat dissipation body having a foundation and a column block extended from the foundation; wherein the cross-sectional size of the foundation is greater than the one of the column block. A fastening means is provided between the foundation and the lamp base such that the foundation is fastened onto the lamp base via the fastening means. The lighting module is secured onto the column block. With such novel design, the heat dissipation effect of the explosion-proof lamp is advantageously improved.

  • Patent number: 8444310
    Abstract: A LED module with fast disassembly function is capable of being disassembled from a hole of a substrate by a tool and includes a lamp base, a LED and fasteners. The lamp base has tabs extending outwards. Each of the tabs is provided with a through-hole corresponding to the hole. The tab is formed with an inclined surface at the periphery of the through-hole. The LED is fixed on the lamp base. Each of the fasteners has a cap. The fastener is disposed through the hole and the through-hole to be fixed thereto. A notch is formed between the cap and the inclined surface. The tool is disposed in the notch to thereby disassemble the fastener from the hole and the through-hole. With this arrangement, the damaged LED can be detached from the substrate rapidly without replacing the whole LED module, thereby reducing the time and cost for maintenance.

  • Publication number: 20080318463
    Abstract: A loose-proof connector includes a screwing sleeve and a connecting body. The screwing sleeve is an annular body and has a circular through hole. The inner wall of the circular through hole is provided with a plurality of recessed arcs that are arranged circumferentially. The connecting body is inserted into the circular through hole of the screwing sleeve. An annular band of the connecting body is provided with protruding arcs to correspond to each recessed arc. The protruding arcs oppose to the any one of the recessed arcs and thus are adjacent thereto. Via this arrangement, the protruding arcs can bounce between any two adjacent recessed arcs, thereby generating a locking effect, and thus the loose-proof effect can be surely achieved.

  • Patent number: 7037131
    Abstract: An adjustable locking device includes a main body, at least a link structure, and at least a buckling device. The main body includes a connection portion. The connection portion provides one end of the link structure to connect thereon. The link structure includes a link element and an adjusting element connected to the link element. The link element provides a buckling device to pivotally connect thereon. The buckling device includes an actuating element and a buckling element. The actuating element and the buckling element are mutually connected, whereby the link structure can be moved within the connection portion of the main body, so as to change the position of the buckling device. The connection tightness between the main body and the connection port is thus enhanced.
