Abstract

The utility model relates to an internally embedded non-section pivot, which is composed of a pivot, a pivot sleeve sheathed on the inner side of the pivot and a tight ring sleeve, wherein the pivot and the exterior of the tight ring sleeve are respectively fixed to a screen (or a main machine body) and the main machine body (or the screen). The inner side of the pivot is provided with a cylinder. The pivot sleeve is sheathed on and covered on the exterior of the cylinder. A plurality of torque force adjusting sheets are surrounded on the pivot sleeve. A cone part is formed on a position corresponding to the tight ring sleeve on the exterior of the torque force adjusting sheets. Mutually matched cone holes are formed in the interior of the tight ring sleeve sheathed on the exterior of the torque force adjusting sheets. The torque force of the non-section pivot can be adjusted by adjusting the position of the tight ring sleeve in respect to the pivot sleeve. Thus, the screen can be definitely positioned on a required angular position for a user in respect to the main machine body.

Description

The inner cased type section of nothing pivot

Technical field

The utility model relates to a kind of inner cased type section of nothing pivot, particularly relates to inner cased type the do not have section pivot of a kind of use at notebook computer or mobile phone or desktop screen.

Background technology

Because scientific-technical progress, computer has become one of indispensable instrument for the people, and for work of going out or the convenient use of giving a lecture, notebook computer more can be subjected to popular liking and and then purchase and use owing to archives material can be carried easily.

Notebook computer is in order to save the space and can be convenient to carrying of people, and major part is designed to liftable screen and main body two major parts, but the pivot that the mat folding covers connects two parts; Notebook computer development so far, existing many research and development that are used to link the pivot of screen and main body, its purpose provides notebook computer more convenient location nothing more than being, makes the user in use, can arbitrarily adjust the viewing angle of screen.

So long as used the people of notebook computer, all can learn, on notebook computer, be provided with main body and screen, screen main body relatively pivot to be opened or is closed and covers, being provided with between screen and main body can be for the pivot that pivots, and pivot must have suitable constraint degree, just can make screen pivot with respect to main body and open, and the location can be provided at any time, watch the needs of screen to make things convenient for the user; Its shortcoming is: pivot is after using one period time, because of screen with respect to the unlatching of main body or close frequent, can cause pivot behind pivot, to produce wearing and tearing, after wearing and tearing, pivot torsion is originally descended, screen can not be positioned at really lift the angular position that to locate after opening,, necessity of being improved be arranged in fact so can make screen produce the problem that to locate really.

Other field of employment, for example: mobile phone or desktop screen etc. also has the application of aforesaid pivot, is narrated no longer one by one at this.

This shows that above-mentioned existing pivot obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.In order to solve the problem that pivot exists, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.

Because the defective that above-mentioned existing pivot exists, the design people is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, and the utilization of cooperation scientific principle, actively studied innovation, in the hope of founding a kind of inner cased type section of nothing pivot of new structure, can improve general existing pivot, make it have more practicality.Through constantly research, design, and after studying sample and improvement repeatedly, create the utility model that has practical value finally.
