Abstract
The utility model discloses a motor switch, which comprises a DC motor, a shell, a lead screw, a switch column, an upper return spring and a lower return spring, wherein the DC motor is installed inside the shell and is fixedly connected with the shell through a screw, the lower return spring is sleeved on the lead screw, and the upper return spring is sleeved on the switch column. The straight-line movement is realized by the thread transmission between the lead screw and the switch column through the rotation movement of the motor so as to realize the opening and the closing of a circuit. The motor switch has the advantages of simple structure, convenient control and long service life.
Description
Technical field
The utility model relates to a kind of switch, relates in particular to the field of switches that a kind of motor switch is mainly used in communication and electron trade and other relevant straight line break-makes.
Background technology
This product mainly is the high performance-price ratio product that cooperates long-distance remote control, and two kinds of similar methods are arranged in the market: the one, adopts the method for simple electric armature pull-core, and shortcoming is the big electric currents of needs, the energy loss height; Another is to adopt cam and photoelectric tube owing to its system complex, expensive price, is unfavorable for promoting the use of.
The utility model content
Technical problem to be solved in the utility model is the defective that overcomes prior art, provides a kind of simple in structure, control convenience, a kind of motor switch of long service life.
For solving the problems of the technologies described above, the utility model provides a kind of motor switch, comprises direct current machine, shell, screw mandrel, switch column upper reset spring, following back-moving spring composition, and described direct current machine is installed in enclosure, and by the screw Joint.
Described screw mandrel links to each other with direct current machine, is with down back-moving spring on the described screw mandrel, and back-moving spring is placed between direct current machine and the switch column down.
Be with upper reset spring on the described switch column, and deflating cap and rubber blanket are installed above the switch column.
Description of drawings
Fig. 1 is the structural representation at the switch column contraction state of a kind of motor switch of the utility model;
Fig. 2 be a kind of motor switch of the utility model stretch out the structural representation of state at switch column;
Fig. 3 is the vertical view of a kind of motor switch of the utility model.
Wherein: the 1-shell; The 2-switch column; The 3-direct current machine; The 4-screw mandrel; The 5-upper reset spring; Back-moving spring under the 6-; The 7-screw; The 8-deflating cap; The 9-rubber blanket.
Embodiment
Be a kind of motor switch of the utility model as shown in Figure 1 and Figure 2.Comprise direct current machine 3, shell 1, screw mandrel 4, switch column 2, upper reset spring 5, following back-moving spring 6 compositions, direct current machine 3 is installed in enclosure, and by screw 7 Joints; Screw mandrel 4 links to each other with direct current machine 3, is with down back-moving spring 6 on the screw mandrel 4, and back-moving spring 6 is installed between direct current machine and the switch column 2 down; Be with upper reset spring 5 on the switch column 2, and deflating cap 8 and rubber blanket 9 are installed above the switch column 2.
When switch column 2 is in contraction state, following back-moving spring 6 is compressed by switch column 2, and at this moment, following back-moving spring 6 has the active force of a stretching, extension, make the screw thread of switch column 2 inwalls to contact with the screw thread on the screw mandrel 4, screw mandrel 4 is along with direct current machine 3 rotates when direct current machine 3 rotates.As shown in Figure 3, part has the restriction of flat position because switch column 2 contacts with shell 1, so switch column 2 can't rotate, make switch column 2 up climb along screw thread, when switch column 2 moves to the position that does not have screw thread, skidding appears, and switch column 2 is in the state that stretches out in certain stroke.
When switch column 2 is in when stretching out state, upper reset spring 5 is in compressive state, at this moment upper reset spring 5 has the active force of a stretching, extension, make the screw thread of switch column 2 inwalls to contact with the screw thread on the screw mandrel 4, when direct current machine 3 concerns by the conversion both positive and negative polarity, direct current machine 3 backward rotation, thus realized that switch column 2 moves down along screw thread.
By rotating via the screw thread transmission of screw mandrel 4 clockwise and counterclockwise of control direct current machine 3, realize rectilinear motion, thereby reached switching purposes with switch column 2.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
Claims (5)
