Description

Novel mouse

Technical Field

The present application relates to a mouse.

Background

The conventional mouse has left and right buttons as shown in fig. 1, and an operation rod is fixed below each button as shown in fig. 2. In general, the operation lever and the mouse button are integrated. The microswitch is arranged below the operating rod, the structure of the microswitch is various, but the basic structure and the principle are the same, namely, the microswitch is provided with an operating button, the operating button can be in the shape of a button, can also be in the shape of a metal elastic sheet, and can also be in other shapes, when a mouse button is pressed down, the operating button of the microswitch is pressed down by the operating rod, the operating button drives the movable spring to move through the linkage mechanism, the contact at the end part of the movable spring is contacted with the normally open contact of the microswitch, a trigger signal is generated, when the mouse button is upwards bounced, the operating button of the microswitch is also upwards moved back to the initial position, so that the contact at the end part of the movable spring is contacted with the normally closed contact of the microswitch, as shown in figure 3.

After the mouse is used for a long time, the operating rod and the operating button of the microswitch are likely to have poor contact, the pressure degree under the button needs to be increased, in addition, the two contacts are in point contact, the contact points are easy to oxidize or pollute, the electric signal transmission is unstable, and the mouse button is discontinuously out of order due to the reasons.

Disclosure of Invention

The utility model aims at solving the problem that the mouse button is out of order discontinuously after the mouse is used for a long time, and provides a novel mouse with stable performance.

The utility model provides a novel mouse, mouse button below is fixed with the action bars, works as when mouse button is pressed, the action bars can with mouse inside micro-gap switch's operation button is pressed, the department opens at the action bars center has penetrating screw hole, the screw hole extends to mouse button's upper surface, the threaded hole is inside to be the screw rod.

Optionally, the screw length is less than or equal to the thread hole depth.

Optionally, the contacts on the upper and lower sides of the end portion of the moving reed of the micro-switch include an arc-shaped elastic sheet and a spring, the arc-shaped elastic sheet protrudes outwards, one end of the arc-shaped elastic sheet is fixed on the moving reed, the spring is fixed between the other end of the arc-shaped elastic sheet and the moving reed, and when the elastic sheet is in a natural state, the spring is in a natural state or a compressed state.

Optionally, the normally closed contact, the normally open contact, and the upper and lower contacts at the movable reed end of the micro switch are all the same in structure.

Optionally, the spring is an insulating spring.

Compared with a traditional mouse, the novel mouse has the advantages that the probability that the keys are discontinuously out of order is greatly reduced, and the service life is prolonged.

Detailed Description

Example one

This embodiment provides a novel mouse, as shown in fig. 4, mouse button 1 below is fixed with action bars 2, works as when mouse button 1 is pressed, action bars 2 can with the operating button 31 of the inside micro-gap switch 3 of mouse is pressed, the department opens at action bars 2 center has penetrating screw hole, the screw hole extends to the upper surface of mouse button 1, the threaded hole is inside to be screw rod 4, the length of screw rod 4 is less than or equal to the degree of depth of screw hole.

When leaving the factory, the screw rod 4 is rotated to enable the lower end surface to be flush with the lower end surface of the operating rod 2, after the mouse is used for a period of time, the operating rod 2 is in poor contact with the operating button 31, and when the mouse button 1 needs to be pressed down forcibly, the screw rod 4 can be rotated to enable the lower end surface of the screw rod 4 to slightly exceed the lower end surface of the operating rod 2, so that the length of the operating rod 2 is prolonged, and when the button 1 is pressed down, the lower end surface of the screw rod 4 drives the operating button 31 to move down.

As shown in fig. 5, the upper end surface of the screw rod 4 is provided with a groove to facilitate the insertion of a screwdriver into the groove to rotate the screw rod 4.

Example two

The embodiment provides another novel mouse, and the contact of the micro switch is improved, as shown in fig. 6. The contact structures on the upper side and the lower side of the end surface of the movable spring plate 32 are the same, and the traditional semispherical structure is changed into a structure of the elastic plate 331 and the spring 332. The elastic sheet 331 may be in the shape of an arc, one end of the elastic sheet 331 is fixed to the movable spring plate 32, the other end protrudes outward, and a spring 332 is disposed between the protruding end and the movable spring plate 32, and when the elastic sheet is in a natural state, the spring is in a natural state or a compressed state.

The normally open contact and the normally closed contact of the microswitch 3 may be configured in the same manner as the above-described contacts.

As shown in fig. 6, when the contact on the upper side of the end of the movable spring plate 32 contacts with the normally closed contact, the point a contacts the point a 'first, then the two contact spring plates gradually change from point contact to surface contact until the point B contacts the point B', in the whole contact process, the two spring plates do not collide with each other violently as the traditional contact, and do not rub or roll, so the contact surface is not easy to oxidize and pollute, and even if the contact surface is oxidized or polluted by individual points, because of the surface contact, other places without oxidation and pollution can still normally contact and generate trigger signals.
