A pressing structure of pressing stationery

Abstract

The invention discloses a press structure for press type stationery. The press structure comprises an installation board, a button and an elastic piece. The elastic piece comprises a spring and an elastic rod body. The elastic rod body is vertically arranged up and down. A limiting block is provided with a first slope and a second slope. The inclination direction of the first slope is the same as that of the second slope. The lower ends of the first slope and the second slope are jointly located on one side of the elastic rod body. The upper ends of the first slope and the second slope are jointly located on the opposite sides of the elastic rod body. A locating groove is located between the upper ends of the first slope and the second slope. The upper end of the elastic rod body is provided with a contact part located in a sliding rail. Compared with the prior art, the position relation of the elastic rod body, the limiting block and the locating groove is used so that the contact part can slide in the sliding rail only through elasticity of the elastic rod body, the problem that the press function fails due to the abrasion of the inner bottom face of a sliding rail in a traditional press mechanism is solved, the service life is long, the press frequency can reach over 500 times, and an installation board is simple in structure and easy to form.

Description

technical field [0001] The invention relates to a pressing structure of a stationery, in particular to a pressing structure for controlling the writing end of a pressing pen or the press nozzle of a pressing correction tape to protrude or shrink back into a casing. Background technique [0002] Existing push-type stationery mainly includes push-type automatic pens and push-type correction tapes, which can make the nib of the push-type automatic pen or the nozzle of the push-type correction tape protrude out of the housing or shrink back into the housing by pressing the button, then When the user is not in use, the tip of the automatic pen or the pressure nozzle of the correction tape can be retracted into the casing, so as not to be polluted by external dust and lose their effectiveness. [0003] The pressing mechanisms of existing push-type automatic pens or push-type correction tapes have basically the same principle. Now take the pressing mechanism of the pressing correc...

Problems solved by technology

It can be seen that when the mounting plate 100 moves up and down, the end of the second arm of the torsion spring will always wear the guide steps. After long-term use, the transitional step between the third guide step 105 and the fourth guide step 106 will The surface is easily ground, causing the second arm of the torsion spring to fail to transition to the fourth guide step surface 106 when the button is pressed down again, and will slide back to the third guide step surface 105, so that the mounting plate cannot be reset and moved again. As a result, the function of the pressing structure is invalid. Usually, the pressing structure will fail after about 100 times of pressing, and the service life is short. At the same time, the setting of each guide surface makes the structure of the mounting plate more complicated and difficult to form.
