Abstract

The utility model discloses a switch which is designed to match with a button. The switch is a ring-shaped body and is compactly sheathed outside the button on a housing. An arc-shaped groove is formed on the inner wall of the ring-shaped body just opposite to the button, and the arc-shaped groove is gradually changed to be shallow from the position of an opening of the button toward both ends. When the switch is used, a user only needs to discretionarily rotate the ring-shaped body. The button is pressed by the pressing function from the shallow end part of the arc-shaped groove for the button, and the circuit can be in a power-on state for a long time. The switch is convenient in use.

Description

A kind of switching device

The utility model relates to a kind of switching device, refers to the switching device that matches with button especially.

Luminous element of the prior art is to come control circuit work by pressing button during use, realizes lighting function.The luminous element of this structure in use, adopts manual pressing button switch, and is luminous for a long time if desired, just must pin button with hand always, uses quite inconvenience.

The purpose of this utility model is to provide a kind of switching device, but its pressing button makes circuit be in channel status for a long time, and is easy to use.

To achieve these goals, solution of the present utility model is:

A kind of switching device is a ring bodies, closely is placed on outside the button on the housing, faces button on the ring bodies inwall and forms a deep-slotted chip breaker, and deep-slotted chip breaker is the shape that shoals gradually from the opening part of button to two ends.

Wherein, the two-port diameter of above-mentioned ring bodies all dwindles slightly, and ring bodies can closely be fastened on the housing by two ports that dwindle.

Above-mentioned ring bodies can be made of two ring plates, offer " U " font breach on one ring plate, corresponding " C " font interface that forms on another ring plate, the two ring plates formation ring bodies that is docking together, " U " font breach and " C " font interface just dock and form the circular hole that is right against button, and deep-slotted chip breaker shoals to two ends gradually from circular hole.Two ring plates form the protruding wall and the groove of fastening respectively at joint, and two ring plates cooperate by protruding wall and groove, and butt joint is buckled into ring bodies.

After adopting said structure, because outside button, be nested with a ring bodies, face button on the ring bodies inwall and form the deep-slotted chip breaker that the centre is dark, two ends shoal gradually, so, during use, only need to rotate ring bodies arbitrarily,, make button press reed by the gradually shallow end squeeze buttons of its deep-slotted chip breaker, reed is deformed, the outer rim of reed contacts with housing, and the centre of reed contacts with feeler, forms a closed-loop path; And the gradually shallow end of deep-slotted chip breaker can make button press reed to the effect of pressing of button always, makes circuit be in channel status for a long time, the convenient use.

Below in conjunction with accompanying drawing and preferred embodiment, the utility model is further described.

Fig. 1 is a three-dimensional exploded view of the present utility model;

Fig. 2 is a three-dimensional combination figure of the present utility model;

Fig. 3 is an axial cutaway view of the present utility model;

Fig. 4 is a radial cross-section of the present utility model;

Fig. 5 is user mode figure of the present utility model.

See also shown in Fig. 1 to 3, the utility model specific embodiment is to use on a kind of luminous element, this luminous element has primary elements such as housing 1, light-emitting component 4, reed 5, button 6, battery 7, during use, by pressing button 6, press reed 5, reed 5 is deformed, the outer rim of reed 5 contacts with housing 1, the centre of reed 5 contacts with feeler 41, thereby make battery 7, feeler 42, light-emitting component 4, feeler 41, reed 5 and housing 1 etc. form a closed-loop path, realize lighting function, cooperate shown in Figure 5.

Wherein ring bodies 2 is made of 21,22 butt joints of two ring plates, two ring plates 21,22 are offered " U " font breach 211 and " C " font interface 221 respectively in a side that connects, two ring plates 21,22 also form the protruding wall 212 and groove 222 that fastens respectively at joint, two ring plates 21,22 are all dwindled slightly in the opposite side port diameter that connects, by two ports that dwindle, two ring plates 21,22 closely are fastened on the housing 1, and this closely being nested with makes two ring plates 21,22 can not be free to slide on housing 1, and can only be in the rotation of using of external force.During 21,22 butt joints of two ring plates, by cooperating of protruding wall 212 and groove 222, snap together and form ring bodies 2, " U " font breach 211 and " C " font interface 221 butt joint just form the circular hole that is right against button 6, and the port that dwindles because of two ring plates 21,22 makes ring bodies 2 face button 6 on inwall and forms a deep-slotted chip breaker 23, and deep-slotted chip breaker 23 is the center with the circular hole of ring bodies 2, the shape dark in the middle of being, that two ends shoal gradually is shown in Fig. 4,5.

Like this, when the utility model uses, cooperate shown in Fig. 4,5, (rotation direction is not limited by Fig. 5 only to need to rotate under Fig. 4 state ring bodies 2 to Fig. 5 states, can be arbitrary to a left side or to the right), by the gradually shallow end squeeze buttons 6 of deep-slotted chip breaker 23, make button 6 press reed 5, reed 5 is deformed, the outer rim of reed 5 contacts with housing 1, the centre of reed 5 contacts with feeler 41, forms a closed-loop path, can realize lighting function; And, because ring bodies 2 is closely to be nested with on housing 1, can not be free to slide, and can only be in the rotation of using of external force, so, after ring bodies 2 goes to Fig. 5 state by Fig. 4 state, if toward revolution, the end that deep-slotted chip breaker 23 is gradually shallow just will not pressed in button 6, make button 6 press reed 5 always always, make the loop be in channel status for a long time, the convenient use.

The utility model is engages button and the switching device that designs, and pressing button makes circuit be in channel status for a long time.Need to prove the push-button switch of above-mentioned switching device, be not subjected to the restriction of the press-button structure described in the above-mentioned specific embodiment, even the whole ring bodies 2 in the utility model also can be for monocycle designs, or be the design of " C " shape ring applicable to any structure.

Claims (4)
