Patent Application
20180259000
This application claims priority to Chinese Patent Application No. 201710146510.3 filed on Mar. 13, 2017 the contents of which, are incorporated by reference herein.
The subject matter herein generally relates to transmission components.
When a printer is used to scan or copy a document, the printer cover is opened so that the document can be placed on the scanning screen, and the cover is pressed against the document before printing or scanning. However, when the cover is closed, especially in confined spaces, a transmission component of the surface of the cover may crush the user's hand, thereby causing a safety hazard.
Implementations of the present disclosure will now be described, by way of example only, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the exemplary embodiments described herein. However, it will be understood by those of ordinary skill in the art that the exemplary embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the exemplary embodiments described herein.
Several definitions that apply throughout this disclosure will now be presented.
The term “outside” refers to a region that is beyond the outermost confines of a physical object. The term “inside” indicates that at least a portion of an object is contained within a boundary formed by another object. The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other feature that the term modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series, and the like.
One end of the gear portion 20 defines a bevel gear 21, and a plurality of gear racks 215 are defined on the bevel gear 21. The gear racks 215 can be engaged with other components of the printer to transmit power. One end of the gear portion 20 away from the bevel gear 21 includes a supporting rod 22, and a receiving space 23 is defined inside a portion of the supporting rod 22. One end of the support rod 22 away from the bevel gear 21 defines an opening 24. The transmission shaft 30 and the resilient member 50 can pass through the opening 24 to be received in the receiving space 23. The supporting rod 22 is received in the positioning column 12 and can be rotated in the positioning column 12.
One end of the transmission shaft 30 includes a protrusion 31, and the protrusion 31 is towards the bevel gear 21 when the transmission shaft 30 is received in the receiving space 23. There is a large static friction force between the sidewall of the transmission shaft 30 and the inner wall of the receiving space 23 to prevent the transmission shaft 30 from falling off from the receiving space 23.
The resilient member 50 can be elastically deformed, and one end of the resilient member 50 is set on the protrusion 31. The resilient member 50 can be received in the receiving space 23 and the other end of the resilient member 50 abuts against one end of the receiving space 23 close to the gear portion 20.
Referring to
The exemplary embodiments shown and described above are only examples. Many details are often found in the art such as the other features of transmission component and a print. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the exemplary embodiments described above may be modified within the scope of the claims.
