Description
Technical field
The present invention relates to a kind of linkage, especially a kind of wide-angle opening-closing hinge mechanism.
The invention further relates to a kind of VTM machines with above-mentioned linkage.
Background technology
Hinge is that the component of relative motion occurs according to certain rule for two parts of constraint in mechanical system；Widely apply
In mechanical system.
Due to mismachining tolerance, it is inevitable that actual hinge, which has gap,.Gap destroys preferable hinge model, leads
The linkage kinematic accuracy and hydraulic performance decline of reality are caused, so that the actual motion off-design requirement of linkage.Separately
Outside, using two parts of hinge（Fixture, opening and closing part）In process, mutual gap can also have processing and miss
Difference, so as to influence the kinematic accuracy and performance of linkage.
VTM machines（Long-distance video automatic teller machine）It is a kind of electromechanics one that some counter services are handled by long-distance video mode
Body equipment；Its shell includes casing and the panel being connected by hinge with casing；Because casing, panel are in process
In, there is mismachining tolerance, cause panel in closed state, still exist between casing between gap, i.e. panel and casing
Can not ideally it be fitted together to.
For the VTM machines shell production of high-quality requirement, this technical problem how is overcome, outstanding aobvious necessity.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of wide-angle opening-closing hinge mechanism, its is simple in construction, and function is real
With；Clearance fine adjustment between two pivoting members that can be by constituting linkage, realizes the fixture connected by linkage
Qian He between opening and closing part；Avoid existing between opening and closing part and fixture and contact friction.
To realize the technical purpose of the above, the present invention will take following technical scheme：
A kind of wide-angle opening-closing hinge mechanism, including two pivoting members, a hinge pins；Two pivoting member difference
For the first pivoting member, the second pivoting member；One end of hinge pin is connected with the first pivoting member, and the other end is then placed in second
In the through hole that pivoting member is opened up along own axes, in the through-hole wall of second pivoting member, one end passes through self-lubricating set
It is connected with the outer wall of hinge pin, the other end is then connected in the way of screw thread is connected with threaded fastener.
As a further improvement on the present invention, described threaded fastener is holding screw.
As a further improvement on the present invention, first pivoting member offers through hole along own axes；Hinge pin
Linked into an integrated entity in the way of tight fit connection with the first pivoting member along the through hole that own axes are opened up.
As a further improvement on the present invention, the outer wall of second pivoting member is provided with for installing opening for opening and closing part
Component installation portion.
As a further improvement on the present invention, the outer wall of second pivoting member is arranged to step type, wherein external diameter compared with
Small one section nestles up the setting of the second pivoting member end, to be used as the opening and closing part installation portion for installing opening and closing part.
As a further improvement on the present invention, the through hole that second pivoting member is opened up along own axes is with decreasing pore size
Mode subsection setup into three sections, be followed successively by enlarged diameter section, middle diameter segment and reduced diameter section, corresponding with enlarged diameter section second
Self-lubricating set is provided between pivoting member through-hole wall and hinge pin outer wall；The second pivoting member corresponding with reduced diameter section
Through-hole wall opens up screw thread, and threaded fastener is equipped with threadably.
Another technical purpose of the present invention is to provide a kind of VTM machines with above-mentioned wide-angle opening-closing hinge mechanism,
The wide-angle opening-closing hinge mechanism being connected including casing, panel and by panel with casing；In wide-angle opening-closing hinge mechanism, the
One pivoting member is fixedly connected by way of welding with casing；Second pivoting member is then connected by rotating brace with panel；
Described rotation brace is fitted with hydraulic spring grease cup.
Described rotation brace is L-shaped to be set, including section and vertical section anyhow, and circular arc between section and vertical section anyhow
Connection；Vertical section is connected with the opening and closing part installation portion in the second pivoting member, and Duan Zeyu panels are connected anyhow.
Technical scheme more than, relative to prior art, the present invention has the following advantages that：
1st, this mechanism can reach the function of wide-angle unlatching by using cylinder hinge connection casing and rotating mass,
Be conducive to the installation of box house accessory.
2nd, hinge inner, can be adjusted to the gap between body hinge, chest hinge by holding screw, subtracted
Unlatching/closing resistance of few panel；The face that the adjustable error that can effectively adjust during due to processing of hinge gap is caused
The gap of plate and casing, it is ensured that the aesthetics of product appearance.
