Description

Novel anti-rotation scissor structure for keyboard keys

Technical Field

The invention relates to the field of anti-rotation scissor structures, in particular to a novel anti-rotation scissor structure of a keyboard key.

Background

The keyboard is the most common and main input device, English letters, Chinese characters, numbers, punctuation marks and the like can be input into a computer through the keyboard, so that commands, input data and the like are sent to the computer, and the keyboard with various shortcut keys is provided.

In current keyboard button structure, the scissors is the essential transmission part who presses down strength of button, current scissors comprises two parts, outer scissors and interior scissors combination, the hole in the middle of the pivot in the middle of the interior scissors and the outer scissors is collocated, interior scissors relies on the axis to carry out the rotation in the mesopore department of outer scissors, however with this kind of condition, interior scissors can be 360 degrees rotations in the outer scissors, this kind of condition can cause interior scissors to overturn in the outer scissors, because the scissors of keyboard pressing structure have the differentiation of positive and negative, if interior scissors rotates and causes the positive and negative to overturn, can be the unable equipment of scissors, must be before the equipment positive and negative of scissors in the manual visual inspection, if the opposite direction, the staff must correct the positive and negative of scissors and just can assemble, so bring unnecessary trouble for the production line equipment, reduce production yield and production quality.

Disclosure of Invention

Technical problem to be solved

Aiming at the defects of the prior art, the invention provides a novel anti-rotation scissor structure of a keyboard key, which solves the problem that the scissor is a necessary transmission part of a pressing force for the key in the existing keyboard key structure of the anti-rotation scissor structure, the existing scissor is composed of two parts, namely an outer scissor and an inner scissor, a rotating shaft in the middle of the inner scissor is matched with a hole in the middle of the outer scissor, the inner scissor rotates in a center hole of the outer scissor by a center shaft, however, under the condition, the inner scissor rotates 360 degrees in the outer scissor, the inner scissor is overturned in the outer scissor due to the condition, the scissor in the keyboard pressing structure has the distinction of the front and the back, if the front and the back of the inner scissor are inverted due to the rotation of the inner scissor, the assembly of the scissor cannot be realized, the front and the back of the inner scissor can be visually checked by workers before the assembly, and if the front and the back of the scissor can be corrected by workers, therefore, unnecessary troubles are brought to assembly of the production line, and the production yield and the production quality are reduced.

(II) technical scheme

In order to achieve the purpose, the invention is realized by the following technical scheme: the utility model provides a new-type anti-rotation scissors foot structure of keyboard button, includes anti-rotation scissors foot structure, including outer scissors and interior scissors, the left and right sides of outer scissors inner wall has all been seted up the outer rotation groove of cutting, two the rear side of outer scissors rotation inslot wall has all been seted up outer spacing breach of cutting, the equal fixedly connected with in the left and right sides surface of interior scissors is cut the axis of rotation, two the equal fixedly connected with in rear side surface of interior scissors axis of rotation is prevented rotating spacing tie, two the inner wall of outer scissors rotation groove all rotates with the relative one end of corresponding interior scissors axis of rotation and is connected.

Preferably, the inner scissors are rotatably connected with the outer scissors rotating groove in the outer scissors through the inner scissors rotating shaft.

Preferably, an external shearing limiting notch is arranged in the hole of the external scissors, the size of the external shearing limiting notch is 0.25mm in the X direction, the diameter of the hole is 0.7mm in the Y direction, and the depth is from the center to the bottom of the hole.

Preferably, the middle shaft of the inner scissors is provided with an anti-rotation limiting tightening strip, the size of the anti-rotation limiting tightening strip is 0.2mm in the X direction and 0.3mm in the Y direction, and the height of the anti-rotation limiting tightening strip is directly flush with the upper surface.

Preferably, when the shaft of the inner scissors rotates in the hole of the outer scissors to a certain angle, the anti-rotation limiting tie bar at the middle shaft of the inner scissors is blocked by the outer scissors limiting notch at the middle hole of the outer scissors.

The working principle is as follows: when the scissors are used, the outer scissors 7 are connected with the inner scissors rotating shaft 3 of the inner scissors 6 through the outer scissors rotating groove 1, the outer scissors 7 and the inner scissors 6 are enabled to rotate, meanwhile, the middle hole of the outer scissors 7 is provided with the outer scissors limiting notch 4 and the anti-rotation limiting tie 5 in the middle shaft of the outer scissors 6 are matched in size, and when the outer scissors 7 and the inner scissors 6 rotate, the outer scissors limiting notch 4 can block the anti-rotation limiting tie 5 to achieve limiting at a certain angle.

(III) advantageous effects

The invention provides a novel anti-rotation scissor structure of a keyboard key. The method has the following beneficial effects:

1. when the pair of scissors is used, the inner scissors and the outer scissors are matched, the front and the back of the scissors can be more conveniently recognized when the scissors are manually installed, the scissors are more convenient to assemble, and the production efficiency is improved.

2. Set up in outer scissors and put the spacing breach of rotating outer scissors of spacing stick assorted with interior scissors, the manual work makes things convenient for the positive and negative of recognition scissors more in the installation, when installing, outer scissors now blocks the spacing stick of preventing rotating of interior scissors for the breach, the mistake appears when avoiding the installation.
