Self-locking mechanism

Abstract

The invention discloses a self-locking accessory mechanism, which comprises the following parts: cylinder component, long axis component, movement shaft and spring component, wherein the cylinder component possesses mutual corresponding upper chute and lower chute; the long axis component is cased in the cylinder component, which pierces the expanding flute through-out hole corresponding to lower chute; the movement shaft pierces lower chute, through-out hole and upper chute, which consists of upper expanding part and lower expanding part; the lower expanding part corresponds to expanding flute; the spring component is cased on the movement shaft with top between upper expanding part and cylinder component, which provides elastic stress to move the movement shaft to be fixed in the expanding flute corresponding to lower expanding part.

Description

technical field [0001] The present invention relates to a self-locking mechanism, in particular to a self-locking mechanism for clamps that apply lubricating oil to shafts. Background technique [0002] For an electronic product generally having a long axis, such as an inkjet printer, an inkjet head is assembled on the long axis, and the inkjet head moves back and forth on the long axis to print desired text or pictures. [0003] The above-mentioned inkjet printers must be coated with lubricating oil on the long axis so that the inkjet head can move back and forth smoothly, and other electronic products with long axes must be coated with lubricating oil on the long axis if they have similar functions. The cloth is lubricated. [0004] Please refer to Fig. 5, which is a schematic diagram of a known inkjet printer coating lubricating oil, wherein an inkjet printer 91 is shown, and a major axis 911 is assembled in the inkjet printer 91, and a spray nozzle is assembled on the m...

Problems solved by technology

[0006] However, in the above-mentioned method, manpower must be used to clamp the clamp 92 and apply lubricating oil on the long axis 911, but when manpower is used to apply force to the clamp 92, it will cause the problem of uneven force application, for example, If a certain part of the major axis 911 is too hard, the clamp 92 will be clamped, causing the clamp 92 to move less smoothly on this part of the major axis 911; otherwise, if the user applies too little force, it will cause clamping. Clamp 92 is too loose at a certain part of major axis 911

[0007] Therefore, the use of manpower to clamp the clamp 92 is likely to cause uneven force, and when the lubricating oil is applied, the movement will not be smooth, or the situation will be too loose, and thus the lubricating oil will be applied unevenly, so that it cannot be achieved. Not ideal for lubrication purposes
