Abstract

The patent discloses a but fix rotation angle's adjustable pivot, including pivot main part (1), nut (2), spring (3), screw rod (4) of taking the pin, pivot main part (1) is including pivot upper part (11) and pivot lower part (12), pivot upper part (11) include two trompils (111) at least, the diameter of screw rod is less than pivot hole (13) in the pivot main part. By providing such a fixed-gear-point rotating shaft with an adjustable angle, the fixed gear point can bear a large external force until the rotating shaft is completely damaged.

Description

But fixed rotation angle's adjustable pivot

Technical Field

The application relates to the field of cash register equipment, in particular to an adjustable rotating shaft of cash register equipment.

Background

The rotating shaft of the cash register products on the market can rotate freely within a certain angle. When the rotating shaft needs to rotate to a certain angle, the rotating shaft stops, mainly depending on the friction force between the rotating shafts. The friction force of the rotating shaft is in a certain range, and the service life of the rotating shaft is greatly influenced by too much friction force. This determines that the normal rotating shaft can not be subjected to too much external force when the rotating shaft is stopped after rotating to a certain angle. Generally, in a food ordering machine with a touch function, when a touch external force is larger than 15N (Newton), a screen rotates, or when a friction force of a rotating shaft fails, the screen rotates easily.

Based on such circumstances, this patent proposes a fixed gear pivot that has adjustable angle. The fixed gear point can bear a large external force until the rotating shaft is completely damaged.

Disclosure of Invention

An object of this application is to provide a can fix rotation angle's adjustable pivot, including pivot main part, nut, spring, the screw rod of taking the pin, the pivot main part includes pivot upper part and pivot lower part, pivot upper part includes two trompils at least, the diameter of screw rod is less than the pivot hole in the pivot main part.

And the pin in the screw with the pin is riveted on the screw.

The rotating shaft upper part is provided with a connecting device which is connected with the upright post component; the rotating shaft lower part is provided with a connecting device which is connected with the base assembly.

This patent realizes the function of fixed gear point through the mode that increases the pin in ordinary pivot, increases the spring simultaneously and realizes the reset function.

The specific implementation mode is as follows:

in order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below based on the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.

The common rotating shaft has self friction, so that the upright post part can not rotate in normal use, but when the upright post part receives large outgoing force, the thrust generated by external force is greater than the self friction of the rotating shaft, and then the upright post starts to rotate by taking the axis of the rotating shaft as the center of a circle.

As shown in figures 1 and 2, holes are formed at proper positions of the upper part and the lower part of the rotating shaft, and the hole forming positions are the holes formed on the upper part of the rotating shaft according to the required fixed angle of a product.

As shown in figure 3, after the screw with the pin is assembled on the rotating shaft, the spring is sleeved on the screw, and then the nut is screwed on, and the pin on the screw is right in the hole of the upper part of the rotating shaft. This patent has increased the screw rod of taking the pin on ordinary pivot basis, and the pin can pass pivot upper and lower piece, can prevent the pivot from using the pivot axle center as the rotation of centre of a circle about the pivot, just can the free rotation if only destroy the pivot upper and lower piece of pin, nevertheless because the pin is the metalwork, needs very big destructive power just to damage it. Such forces are not present under normal use conditions.

When the user has the requirement for adjusting the angle of the visual angle of the product, the end of the screw rod provided with the spring nut can be pressed. As shown in fig. 4, when the screw receives an external force, the pin on the screw is driven to move back and forth together, and the spring is compressed at the same time. After the pin retreated to the hole of leaving the piece on the pivot, the piece was in the pivot after not blockking of pin, and the user applyed external force to the product stand, just so can make the stand produce and rotate, and after the stand rotated certain angle, the pin can reset under the effect of spring, passes another downthehole of piece on the pivot again.

Fig. 5 and 6 show the actual effect of the rotating shaft itself before and after the angle adjustment, and the installation of the rotating shaft behind the cashier device.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present application without departing from the spirit and scope of the application. Thus, if such modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is intended to include such modifications and variations as well.

It will be evident to those skilled in the art that the present application is not limited to the details of the foregoing illustrative embodiments, and that the present application may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
