Description
Technical field:
The utility model relates to a kind of pin connected assembly structure, is meant that especially a kind of pivot is reliable, and can prevent fully that assembly from loose pin connected assembly structure taking place.
Background technique:
The computer liquid crystal screen that is subjected to the Consumer to show to look at present mainly is to utilize pin connected assembly to carry out the adjustment at screen tilt angle, and therefore, this pin connected assembly also must carry the weight of this screen except in order to the screen that is pivoted.
Use the screen pin connected assembly on the what notebook computer at present, as Taiwan patent announcement number No. 413340 " can adjust the hinge rotating shaft structure of torsion ", it mainly comprises:
One first rotating shaft, an end of this rotating shaft is equipped with plural screw, and for solid with the computer spiral shell, end then is provided with an axle center in addition, and the end is provided with a screw section before this axle center, and cuts and be provided with a suitable tangent plane;
One plural pad is on the sheathed what axle center;
One location piece, it is provided with two location lugs that are symmetry, is set on the described axle center;
One fixed plate is to be set on the described axle center;
One ends loose nut, is solid this screw section of what of spiral shell, can produce fastening force to pad and fixed plate, produces stable, an appropriate torsion value and use;
One second rotating shaft, one end of this rotating shaft is equipped with plural screw, for solid with the computer spiral shell, the other end then is provided with the fit portion that is hollow in, but this first rotating shaft of fit what ends, and this fit portion opening has two symmetrical notches, and it is chimeric to be symmetrical location lug for two of this location piece.
This pivot torsional axis can be adjusted the screen angle of inclination, and by ending the elasticity of loose nut spiral shell when solid, reaches the purpose of adjusting torque value; But the member that this pivot torsional axis is not only formed is numerous and diverse, and by the what screen when repetitiousness is adjusted the angle of inclination, first, second rotating shaft of this pivot torsional axis is when pivoting, pad on the axle and location piece can rotate thereupon, and pad and location piece are subjected to for a long time turning and very easily cause loosely organizedly, even cause screen that the situation at the suitable angle of inclination of what takes place to locate.
Summary of the invention:
The purpose of this utility model is to improve the shortcoming of prior art, prevents because of the long-term day by day loose pin connected assembly structure of pivot movement recurring structure and provide a kind of.
For achieving the above object, the utility model is taked following design proposal:
This pin connected assembly structure is made up of rotating shaft, position shelf, banking stop, pad, locating washer and locking cap; Wherein, described rotating shaft one end is provided with several positioning holes, and the fixing positioning part of what screen support body, and the other end then is provided with the axle center, and two corresponding side surface in described axle center are provided with tangent plane, and its outboard end also is provided with screw thread; Described position shelf is to be a L type, and the one side is provided with the fixedly fixed hole of what screen rear side, and side then is provided with the open-work that penetrates for the axle center in addition, and this place, open-work top is shaped on a restraining groove; Described banking stop is to be located between rotating shaft and position shelf, and its lateral margin is extended with a braking part in restraining groove; Described pad is to be located between position shelf and the banking stop; Described locating washer is located at the opposite side of position shelf, and the tangent plane of its fitted shaft heart both sides, center is formed with the stop perforation, forms the state that holds with the axle center; The screw thread of described locking cap system and axle center outboard end forms locking.By said structure, can prevent effectively that pin connected assembly is because of the day by day loose phenomenon of long-term pivotal action recurring structure.
The utility model is simple in structure, pivot flexibly and reliably, and it is loosely organized to prevent that long-term pivotal action from causing.

Fig. 2 is a combination schematic representation of the present utility model
Fig. 3 is the A-A cut-away view of Fig. 2
Embodiment:
See also Fig. 1, shown in Figure 2, the structure of this pin connected assembly mainly provides the computer liquid crystal screen and is hubbed on the support body, carries out the adjustment of angle tilt on support body for screen.This pin connected assembly system is formed by rotating shaft 10, position shelf 20, banking stop 30, pad 40, locating washer 50 and locking cap 60 structure of organizing; Wherein: rotating shaft 10 1 ends are provided with several fixed holes 11, and are formed with one for making the fixing positioning part 12 of screen support body, and the other end is provided with axle center 13, the 13 liang of respective side tangent planes 14 in axle center, and its outboard end is provided with screw thread 15.Position shelf 20 is to be just like L type, and the one side is provided with the fixedly fixed hole 21 of what screen rear side, and side is provided with for the open-work 22 that axle center 13 is penetrated in addition, and there is a restraining groove 23 at place, open-work 22 tops.Banking stop 30 is established 20 of what rotating shaft 10 and position shelfs, and its lateral margin appropriate location is extended with a braking part 31 in the restraining groove 23 of position shelf 20.Pad 40 is to establish between what position shelf 20 and the banking stop 30.Locating washer 50 is to establish what position shelf 20 side in addition, and its center fitted shaft heart 13 both sides tangent planes 14 are formed with stop perforation 51.Locking cap 60 is that the screw thread 15 with axle center 13 outboard ends forms locking.
Structure by above-mentioned pin connected assembly, when this computer liquid crystal screen is adjusted in the enterprising line tilt of support body, fixedly the position shelf 20 of what screen rear side rotates on axle center 13, when position shelf 20 rotates, braking part 31 restrictions (please consulting shown in Figure 3 simultaneously) that the restraining groove 23 at its place, top is promptly extended by banking stop 30 are adjusted the screen angle of inclination under the suitable angle limits of restraining groove 23.
What deserves to be mentioned is, be to utilize screen to carry out the angle tilt adjustment position shelf 20 is rotated on the axle center of rotating shaft 10 by this pin connected assembly of Yan, but and position shelf 20 and pad 40 mat restraining grooves 23 and braking part 31 spacing mutually, to limit its rotation amplitude.Moreover, if what position shelf 20 is the locating washer 50 of side in addition, be provided with the stop perforation 51 that can form the state of holding with axle center 13 both sides tangent planes 14 by the what center, therefore, position shelf 20 is when rotating, this locating washer 50 can't be turned, and by this, can prevent pivot start that pin connected assembly is long-term and the day by day loose phenomenon of recurring structure.
