Description
Technical field
The present invention relates to a kind of attaching parts, relate to a kind of attaching parts installing castor specifically.
Background technology
The article be made up of rod member, wherein use multiple attaching parts, when connecting multiple rod member, can relatively rotate between each rod member and one of them rod member need install castor time, because the structure of existing attaching parts limit, an attaching parts cannot realize, adopt multiple attaching parts that structure can be caused very complicated, be the application for a patent for invention of the Multifunctional walking acid of 201310049906.8 as application number, its complex structure, and the rotation that can affect castor when installing the rod member angle change of castor.
Summary of the invention
The object of this invention is to provide a master-slave type castor attaching parts, it can connect multiple relatively turnable rod member when being provided with castor, and when the angle between son, female component is 180 degree, female component can prop up chapelet component, and structure is simple.
To achieve these goals, technical solution of the present invention is:
One master-slave type castor attaching parts, comprise female component, at least one sub-component, adapter shaft, female component one end is castor installation end, the other end is pipe link installation end, castor installation end end face is provided with castor, be pin jointed end in the middle part of female component, sub-component one end is pipe link installation end, the other end is pin jointed end, female pin jointed end of component and the pin jointed end of sub-component are all articulated with on adapter shaft, adapter shaft is provided with for limiting female component, the axially stop block of sub-member position, the upper surface of the castor installation end of female component is provided with boss, when angle between the pipe link installation end and the pipe link installation end of sub-component of female component is 180 degree, described boss is resisted against sub-component lower surface near pin jointed end position.
Master and slave type castor attaching parts of the present invention, wherein, described sub-component is two or more, each sub-element structure is identical, the pin jointed end of each sub-component is all articulated with on adapter shaft, when angle between the pipe link installation end and the pipe link installation end of arbitrary sub-component of female component is 180 degree, boss is resisted against this sub-component lower surface near the position of pin jointed end.
Master and slave type castor attaching parts of the present invention, wherein, described axially stop block comprises the positive stop lug boss being arranged at adapter shaft front end and the stop screw being arranged at adapter shaft rear end.
Master and slave type castor attaching parts of the present invention, wherein, the pipe link installation end of described female component and the pipe link installation end of sub-component is equipped with negative thread.
After adopting such scheme, because master and slave type castor attaching parts of the present invention comprises female component, sub-component, female component, sub-component is articulated with on adapter shaft, and female component one end is provided with castor, the other end is pipe link installation end, sub-component one end is pipe link installation end, therefore sub-component, female component can connect multiple rod member that can mutually rotate, structure is simple, easy to use, the position of rod member can not affect castor and rotate, because the upper surface of the castor installation end of female component is provided with boss, son, when angle between female component is 180 degree, female component props up chapelet component by boss.

Detailed description of the invention
As Fig. 1, shown in 2, master and slave type castor attaching parts of the present invention, comprise female component 11, sub-component 13, adapter shaft 15, female component 11 one end is castor installation end 111, the other end is pipe link installation end 113, castor installation end 111 end face is provided with castor 12, pipe link installation end 113 is provided with negative thread for installing head rod, be pin jointed end 115 in the middle part of female component 11, sub-component 13 one end is pipe link installation end 131, the other end is pin jointed end 133, pipe link installation end 131 is provided with negative thread for installing the second pipe link, female pin jointed end 115 of component and the pin jointed end 133 of sub-component are all articulated with on adapter shaft 15, adapter shaft 1 front end is provided with positive stop lug boss 151, rear end is provided with stop screw 152, for limiting female component, the axial location of sub-component on adapter shaft 15, the upper surface of the castor installation end 111 of female component 11 is provided with boss 117, when pipe link installation end 113 and the sub-component of female component pipe link installation end 131 on the same line time, boss 117 is resisted against sub-component 13 lower surface near pin jointed end 133 position.
As shown in Figure 3, when group component 13 is three, each sub-component 13 structure is identical, the pin jointed end 133 of each sub-component is all articulated with on adapter shaft 15, when angle between the pipe link installation end 113 and the pipe link installation end 131 of arbitrary sub-component of female component is 180 degree, boss 117 is resisted against this sub-component 13 lower surface near pin jointed end 133 position.
After master and slave type castor attaching parts of the present invention connects upper connecting rod, sub-component, female component can rotate arbitrarily adjustment angle, meet different using function, and sub-component also can be used alone.
The above embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that the common engineering staff in this area make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determine.
