    Abstract: The disclosure is a nut structure for an electric pushing rod. The electric pushing rod has a guide screw (A) with an outer thread (A1). The nut structure includes a metal cylinder (10) and a plastic intermediate component (20). The metal cylinder (10) has a pivot hole (11) being passed through by the guide screw (A). An inner wall of the pivot (11) is provided with an inner thread (12). The plastic intermediate component (20) covers the inner thread (12) and is disposed of between the outer thread (A1) and the inner thread (12). The plastic intermediate component (20) includes a fixed side thread (21) mounted on the inner thread (12) and a driving side thread (22) screwed with the outer thread (A1). Therefore, the strength may be enhanced to avoid both the nut structure from being broken and the driving side thread (22) from getting stripped.

    Abstract: A leg structure of an electric table includes a pair of support assemblies (10), multiple horizontal rods (20) and a pair of drive assemblies (30). The support assemblies (10) are arranged spacedly and parallelly to each other. Each support assembly (10) includes a connecting rod (11) and a pair of telescopic posts (12). Each telescopic post (12) is connected and fixed to the connecting rod (11). Each horizontal rod (20) is separately connected to each support assembly (10) and is parallel to each other. Each drive assembly (30) is separately received in each support assembly (10) for driving each telescopic post (12) to ascend or descend. Therefore, the leg structure of an electric table may be easily assembled and the whole structure is stable.

    Abstract: An actuator and a transmission structure thereof. The transmission structure (3) includes a screw nut (31) and a ratchet guiding sleeve (32). The screw nut (31) includes one or a plurality of pawls (311). The ratchet guiding sleeve (32) is mounted on the screw nut (31), and the screw nut (31) is able to rotate relative to the ratchet guiding sleeve (32). The ratchet guiding sleeve (32) includes a ring ratchet (321) disposed on an inner circumference thereof and a plurality of track slots (322) disposed on an outer circumference thereof. One or a plurality of pawls (311) abut against the ring ratchet (321), thereby achieving the effect of smooth movements of the actuator (10) and the transmission structure (3).

    Abstract: A linear actuator (1) and the centrifugal safety device (50) thereof is disclosed. The safety device (50) includes an outer socket (51) having a stop portion (512) and a first accommodation portion (513), an inner socket (53) having a raised portion (531) and a second accommodation portion (532) and a centrifugal assembly (55) having a centrifugal block (551) and an elastic element (555). The inner socket (53) drives the centrifugal assembly (55) to rotate. If the centrifugal force of the centrifugal block (551) is smaller than the elasticity of the elastic element (555), then the centrifugal block (551) is limited in the second accommodation portion (532) by the elastic element (555), or else the centrifugal block (551) moves into the first accommodation portion (513) and clamped by the raised portion (531) and the stop portion (512).

    Abstract: The disclosure is a linear actuator. A transmission mechanism includes a motor, a gear set and a screw rod. A releasing mechanism is disposed between the gear set and the screw rod and includes a driving gear, a first clutch, a second clutch and a sliding sleeve. A toggle restraining mechanism includes a stem, a rotating element and a restraining assembly. The rotating element has a restraining hole and a rotating arm. The restraining assembly includes a restraining presser, a restraining spring and an engaging element. The stem is moved to rotate the rotating element, the rotating arm is rotated with the rotating element to push the sliding sleeve. The sliding sleeve is pushed by the rotating arm to separate from the second clutch. The engaging element is engaged in the restraining hole to restrain the rotating element from rotating when the rotating element is rotated to a specific angle.

    Abstract: An electric push rod with a dual brake mechanism includes an electric motor, a transmission device, a first brake mechanism and a second brake mechanism. The electric motor has a driving wheel. The transmission device is installed on a side of the electric motor and includes a deceleration mechanism, a lead screw, a driven wheel, and a telescopic pipe. The deceleration mechanism is disposed between the driving wheel and the driven wheel. The lead screw is sheathed with the driven wheel and the driven wheel is driven by the electric motor to rotate together with the lead screw. The telescopic pipe and the lead screw are screwed and driven. The lead screw is sheathed with the first brake mechanism formed on a side edge of the driven wheel. The lead screw is sheathed with the second brake mechanism disposed between the driven wheel and the telescopic pipe.
