Summary of the invention
The purpose of this utility model provides a kind of recreational vehicle electric thruster with removable pin, it mainly is that solution existing in prior technology thruster can't be regulated the distance between chassis and the screw mandrel, make under specific circumstances, the operating distance of thruster can't extend, and bearing set can't stop under the state that action is finished in the course of the work automatically, the technical matters of waste electric power etc.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
The recreational vehicle electric thruster of band removable pin of the present utility model, comprise drop-gear box, be connected with outer tube and motor on the drop-gear box, motor is connected with self-resetting switch, motor is connected with screw mandrel in being arranged on outer tube by the transmission device that is located in the drop-gear box, screw mandrel is by the interior pipe that has been threaded, inner tube portion is connected with the chassis, motor, source switch connect by lead, the fixed end that it is characterized in that described chassis stretches into interior pipe inside, the fixed end on chassis is provided with some pin-and-holes, and the fixed orifice of itself and screw mandrel end is complementary.By the pin-and-hole on fixed orifice that pin is inserted the screw mandrel end and the chassis that is complementary, make thruster can regulate the distance between chassis and the screw mandrel, the operating distance of the thruster that can extend like this.
As preferably, the distance of described adjacent pin span equates, and distance at interval can be according to the required setting in place.
As preferably, described drop-gear box is provided with overload protective device, is provided with the thermoinduction sheet in the overload protective device, and it is connected by lead with motor, source switch.Overload protective device can connect power supply, wire fuse, and when the electric current that passes through in the overload protector acquired a certain degree, heat was experienced in the thermoinduction sector-meeting, and overload protective device can cause circuit to disconnect, thereby stops the action of electronic thruster, has saved the energy.
As preferably, described transmission device is: be engaged in the intermediate gear on the motor shaft, by the output gear that tween drive shaft matches with intermediate gear, output gear is connected with output shaft, and output shaft is connected with screw mandrel.Gear transmission is convenient to motor power is sent to screw mandrel, thereby makes electronic thruster motion.
Therefore, the utlity model has thruster and can regulate distance between chassis and the screw mandrel, make under specific circumstances, the operating distance of thruster can extend, and bearing set can stop under the state that action is finished in the course of the work automatically, energy savings, characteristics such as rational in infrastructure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is a kind of structure for amplifying scheme drawings of Fig. 1 drop-gear box;
Accompanying drawing 3 is a kind of circuit diagrams of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the recreational vehicle electric thruster of the band removable pin of this example, as Fig. 1, it has a drop-gear box 1, is connected with an outer tube 2 and motor 3 on the drop-gear box, and motor is connected with pipe 6 in resetting toggle switch 4, being provided with in the outer tube.Be provided with screw mandrel 5 in the interior pipe.Inner tube portion connects chassis 7.Pipe 6 inside in the fixed end on chassis 7 stretches into, the fixed end on chassis is provided with 5 pin-and-hole 7-1, and the fixed orifice of itself and screw mandrel 5 ends is complementary.As Fig. 2,3 in the motor that is located in the drop-gear box is combined with intermediate gear 9, and intermediate gear matches with output gear 11 by tween drive shaft 10, and the output gear other end is connected with output shaft 12, output shaft be connected with screw mandrel 5.And screw mandrel is to be connected with interior pipe 6 by screw thread.Drop-gear box 1 is provided with overload protective device 8, is provided with the thermoinduction sheet in the overload protective device, and it is connected by lead with motor, the switch that is located on the drop-gear box.As Fig. 3, overload protective device A one end connects direct supply M by wire fuse R, and the other end connects DC machine L by the toggle switch 4 that resets certainly, also is connected with rotor switch and indicator lamp in the loop.
