Description
Technical field
The utility model relates to a kind of fast lock, relates in particular to a kind of fast lock that is mainly used in stage lamp and mounts the energy self adaptation aperture of connection.
Background technology
Fast lock is a kind of for the interim connection lock connecting between object, utilize the embossing axle on the locking bar of fast lock to realize with elasticity spheric washer the object that two objects are connected fast, dismounting also only needs brute force to extract, do not need screw, change the instrument such as cutter, spanner, so application is very extensive in interim mechanical connection.
Such as the present stage computer installation of class light fixture of shaking the head, be all generally with fast lock, lamp hanging hook and light fixture joint connection in site to be suspended on suspension rod or truss after good again, after the curtain falls, again lamp is hooked up down to convenient disassembly.
Fast lock need to insert locking bar the connecting hole of two objects in the time of application, if the connecting hole aperture of all objects is all basically identical with the external diameter of locking bar, the effect of locking is very good.But in actual applications, the connecting hole aperture of dissimilar object, the different objects of same type object is difficult to identical, and too many if connecting hole aperture is greater than locking bar external diameter, locking bar can rock, and causes the rate of tension deficiency after locking, connects insecure; If connecting hole aperture is less than locking bar external diameter, locking bar is difficult to insert connecting hole, cannot realize the connection between object.
Because the locking bar of existing fast lock is fixing solid construction, its external diameter cannot regulate, and does not also have other accessory can realize the function that external diameter regulates, so cannot address the above problem.Can only add when being necessary some pads between locking bar and connecting hole hole wall, but this mode not only bother, lack of standardization, and effect is also poor, so that the application of fast lock limited to.
Utility model content
The purpose of this utility model be just to provide in order to address the above problem a kind of can be within the specific limits according to the fast lock in connecting hole pore size self adaptation aperture.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The fast lock in energy self adaptation aperture, comprises locking bar, handle sheet, mount pad, elasticity spheric washer and embossing axle, and described handle sheet is installed on described mount pad, described locking bar comprises fixing locking bar and mobile locking bar, the upper end of described fixing locking bar is connected with the lower end of described mount pad, described elasticity sphere gasket sleeve is loaded on described fixing locking bar, the hypomere of described fixing locking bar is " n " shape cylinder, described mobile locking bar is installed on the hollow interlayer of described " n " shape cylinder, described mobile locking bar comprises that two outsides are circular arc, inner side is the sub-locking bar of plane, the both sides of described sub-locking bar are respectively equipped with raised line, the inner surface of two side plates of described " n " shape cylinder is provided with the groove identical with the height of described raised line, the homonymy raised line of two described sub-locking bars is placed in respectively the both sides in corresponding described groove, the inner surface of described sub-locking bar is provided with multiple counterbores that are arranged above and below, and between the corresponding counterbore on two described sub-locking bars, stage clip is installed, the lower end of described sub-locking bar is evagination circular arc, and two described embossing axles are installed on respectively the hypomere outer surface of two described sub-locking bars near the position at turning.
" n " shape cylinder here, specifically refer to the groove that the equal opening in both sides and lower end is set in the radial center part of a cylinder, the axial cross section of whole cylinder is just as " n " word, so be called " n " shape cylinder, its role is to provide the installing space of mobile locking bar, utilize the groove of two side plates to carry out the sub-locking bar of mobile locking bar spacing simultaneously, two sub-locking bars can only be slided at its radial direction small distance; Mobile locking bar is directly to contact with connecting hole hole wall in the time of application, stage clip between two sub-locking bars makes mobile locking bar have outside elastic force, so, as long as the aperture of connecting hole is greater than the minimum outer diameter (external diameter when the inwall of two sub-locking bars is adjacent to mutually) of mobile locking bar and is less than its maximum outside diameter (external diameter when two sub-locking bars as far as possible outwards flick), mobile locking bar all can fit tightly with connecting hole, realizes the firm connection between two objects; The lower end of sub-locking bar is set to evagination circular arc, is beneficial to mobile locking bar and inserts smoothly in connecting hole.In said structure, mobile locking bar is combined as a cylinder in two side plates of the fixing locking bar of minimum outer diameter state time domain, so mobile locking bar profile is not a cylinder, but is similar to both sides cut one cylindrical shape at axial direction.
In order to ensure mobile locking bar and connecting hole close contact and be not subject to the impact of fixing locking bar, when the inner surface of two described sub-locking bars is adjacent to mutually, the external diameter of described mobile locking bar is not less than the external diameter of described fixing locking bar.
The beneficial effects of the utility model are:
The utility model will be designed to have the mobile locking bar of outside stretching, extension trend for the locking bar contacting with connecting hole hole wall, thereby make this fast lock can automatically adapt to the connecting hole in certain limit aperture and keep firm connect, greatly improved the adaptive capacity of this fast lock.
