Technical field
This utility model relates to auto heterodyne equipment, particularly relates to a kind of self-shooting bar clamping device upset retaining mechanism and self-shooting bar。
Background technology
Self-shooting bar is the auto heterodyne emperorship in the fashionable world, and it can be arbitrarily flexible between 20 centimetres to 120 centimetre lengths, and mobile phone or idiot camera only need to be fixed on expansion link by user, can be achieved with multi-angle by remote controller and autodynes。Self-shooting bar is generally of the clamping device for clamping mobile phone or panel computer and expansion link, and clamping device is fixed on the movable end of expansion link。Owing to adjust shooting angle, the clamping device of most of self-shooting bars is all can overturn around the movable end of expansion link on the market, and owing to needing fixing mobile phone/panel computer after angle adjustment, clamping device needs to be relatively fixed in some angle, thus just there being the upset retaining mechanism of clamping device。The upset retaining mechanism of most of self-shooting bar clamping devices is to be provided with, in hinge connection, the adjustment screw or nut that are perpendicular to expansion link, this structure can protrude a twist grip in the direction being perpendicular to expansion link, after clamping device is folded, twist grip can seem that comparison is lofty, affects the overall appearance effect of self-shooting bar。It addition, general self-shooting bar is when pulling out expansion link, it is need to grasp clamping device to be pulled out by expansion link, causes Consumer's Experience not good。
Utility model content
The purpose of this utility model is in that the defect for overcoming prior art, and provides a kind of self-shooting bar clamping device upset retaining mechanism and self-shooting bar, can improve the overall appearance effect of self-shooting bar, can improve again the Consumer's Experience in pull-out expansion link process。
For achieving the above object, this utility model is by the following technical solutions:
Self-shooting bar clamping device upset retaining mechanism, it union joint included for fixing connection self-shooting bar expansion link movable end, union joint is fixed with a bearing pin, clamping device end is provided with mean for the connection cylinder that bearing pin is through。Retaining mechanism also includes threaded post and the thread barrel with internal thread hole, and threaded post front end is with external screw thread, and threaded post rear end is inserted in bearing pin；When clamping device is locked, the external screw thread of threaded post is threadeded with the internal thread hole of thread barrel, and the nozzle of thread barrel is supported mutually with being connected cylinder outer wall, connects cylinder inner wall and produce mutual thrust to realize locking with bearing pin under the thrust of thread barrel。
Further, union joint is provided with two symmetrically arranged hangers, and bearing pin runs through two hangers, and the axial-rotation degree of freedom of bearing pin is zero。
Further, one of them termination cross section of bearing pin is regular pentagon, and described hangers is provided with the regular pentagon through hole of the regular pentagon termination for being inserted in bearing pin。
Further, connect cylinder and be divided axially into two parts of formed objects along bearing pin, leave between two parts that run through for threaded post, allow threaded post around the gap of bearing pin middle shaft rotation。
Further, the outer end of thread barrel is fixed with handle。
The invention also discloses a kind of self-shooting bar。This self-shooting bar includes clamping device and expansion link, also includes retaining mechanism disclosed above。
This utility model compared with prior art provides the benefit that: this utility model by being threaded post and thread barrel on bearing pin, can be good at clamping device carries out upset locking, threaded post is coaxial with expansion link with thread barrel simultaneously, when clamping device folds, will not seeming lofty at side, overall appearance effect is improved, and, when needs pull out expansion link, it is possible to realizing by pulling out thread barrel, Consumer's Experience is preferably。

Detailed description of the invention
In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment the technical solution of the utility model it is described further and illustrates。
The concrete structure of this utility model embodiment is as shown in Figures 1 to 4。
As depicted in figs. 1 and 2, the retaining mechanism 20 of the present embodiment includes for the union joint 24 of fixing connection self-shooting bar expansion link movable end, threaded post 21 and the thread barrel 22 with internal thread hole。
As depicted in figs. 1 and 2, union joint 24 is fixed with bearing pin 25。Specifically, union joint 24 is provided with two symmetrically arranged hangers 241, and bearing pin 25 runs through two hangers 241, and the axial-rotation degree of freedom of bearing pin 25 is zero。Termination 251 cross section of bearing pin 25 is regular pentagon, and hangers 241 is provided with the regular pentagon through hole for being inserted in bearing pin 25 regular pentagon termination 251。After the through hole of hangers 241 is inserted in bearing pin 25 termination 251, bearing pin 25 just cannot rotate relative to hangers 241。Certainly, in other embodiments, regular pentagon can be made in two terminations of bearing pin。
As shown in Figures 1 to 4, threaded post 21 front end is with external screw thread, and threaded post 21 rear end is inserted in bearing pin 25, and threaded post 21 can around bearing pin 25 central axis。The external screw thread that thread barrel 22 internal thread hole is with threaded post 21 matches, and namely the external screw thread of threaded post 21 is threaded with the internal thread hole of thread barrel 22, and therefore threaded post 21 can be threaded in or out the internal thread hole of thread barrel 22。
As shown in Figures 2 to 4, the outer end of thread barrel 22 is fixed with handle 23, it is possible to improve experience when threading cylinder 22 or internal thread broaching cylinder 22, it is also possible to improve appearance。
As depicted in figs. 1 and 2, clamping device 10 end is provided with mean for the connection cylinder 11 that bearing pin 25 is through。Connect cylinder 11 and be divided axially into two parts of formed objects along bearing pin 25, leave between two parts that run through for threaded post 21, allow threaded post 21 around the gap 12 of bearing pin 25 middle shaft rotation。
Use procedure:
1), when clamping device 10 being locked, by twist grip 23, thread barrel 22 (Fig. 1 direction A) clockwise is screwed in, be threaded to the nozzle of thread barrel 22 be connected cylinder 11 outer wall and mutually support and thread barrel 22 can not screw in till；Now, thread barrel 22 produces thrust (Fig. 4 direction C) to connecting cylinder 11, and fixed bearing pin 25 is produced pulling force (Fig. 4 direction D) by threaded post 21, connect and can produce mutual thrust between cylinder 11 inwall and bearing pin 25 outer wall, cause needing overcoming the bigger frictional force between the two can turning and clamping device 10, therefore clamping device 10 is locked, it is impossible to upset。
2) when clamping device 10 being unlocked, by twist grip 23, thread barrel 22 (Fig. 1 direction B) counterclockwise is screwed out, the thrust connected between cylinder 11 inwall and bearing pin 25 outer wall tapers into, frictional force between the two also can taper into, time frictional force vanishing, clamping device 10 just unlocks completely, unfettered, it is possible to overturn around bearing pin 25 easily。
As it is shown in figure 5, the self-shooting bar of the present embodiment includes the retaining mechanism 20 of clamping device 10, expansion link 30 and the present embodiment。
Set forth above only further illustrate technology contents of the present utility model with embodiment; so that reader is easier to understand; but not representing embodiment of the present utility model and be only limitted to this, any technology done according to this utility model extends or recreation, all by protection of the present utility model。
