Abstract
A male and female type trundle connecting piece comprises a female component, at least one male component and a connecting shaft. One end of the female component is a trundle mounting end, and the other end of the female component is a connecting rod mounting end. A trundle is mounted on the end face of the trundle mounting end, and a hinged end is arranged in the middle of the female component. One end of the male component is a connecting end mounting end, and the other end of the male component is a hinged end. The hinged end of the female component and the hinged end of the male component are both hinged to the connecting shaft which is provided with an axial limiting device which is used for limiting the position of the female component and the position of the male component. The upper surface of the trundle mounting end of the female component is provided with a boss. When the included angle between the connecting rod mounting end of the female component and the connecting rod mounting end of the male component is 180 degrees, the boss abuts against the position, close to the hinged end, of the lower surface of the male component. The male and female type trundle connecting piece can be connected with a plurality of rods which can rotate relatively under the condition that the trundle is mounted, when the included angle between the male component and the female component is 180 degrees, the female component can support the male component, and the structure is simple.
Description
Technical field
The present invention relates to a kind of attaching parts, relate to a kind of attaching parts that castor is installed specifically.
Background technology
The article that constituted by rod member, wherein use a plurality of attaching partss, when need connect a plurality of rod members, can relatively rotate between each rod member and one of them rod member need castor be installed the time, limit because of the structure of existing attaching parts, an attaching parts can't be realized, adopt a plurality of attaching partss can cause structure very complicated, be the application for a patent for invention of 201310049906.8 multifunctional assistant driving as application number, its complex structure, and the rod member angle that castor is installed can influence the rotation of castor when changing.
Summary of the invention
The purpose of this invention is to provide a master-slave type castor attaching parts, it can connect a plurality of relatively turnable rod members being equipped with under the situation of castor, and the angle between the son, female member is 180 when spending, and female member can prop up the chapelet member, and is simple in structure.
To achieve these goals, technical solution of the present invention is:
One master-slave type castor attaching parts, comprise female member, at least one sub-member, adapter shaft, female member one end is the castor installation end, the other end is the pipe link installation end, on the castor installation end end face castor is installed, female member middle part is pin jointed end, sub-member one end is the pipe link installation end, the other end is pin jointed end, the pin jointed end of female member and the pin jointed end of sub-member all are articulated on the adapter shaft, adapter shaft is provided with for the female member of restriction, the axially stop block of sub-member position, the upper surface of the castor installation end of female member is provided with boss, when the angle between the pipe link installation end of the pipe link installation end of female member and sub-member is 180 when spending, described boss is resisted against sub-member lower surface near the pin jointed end position.
Master and slave type castor attaching parts of the present invention, wherein, described sub-member is more than two, each sub-element structure is identical, the pin jointed end of each sub-member all is articulated on the adapter shaft, when the angle between the pipe link installation end of the pipe link installation end of female member and arbitrary sub-member is 180 when spending, boss is resisted against this sub-member 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 that is arranged at the adapter shaft front end and is arranged at the stop screw of adapter shaft rear end.
Master and slave type castor attaching parts of the present invention wherein, is equipped with negative thread on the pipe link installation end of described female member and the pipe link installation end of sub-member.
After adopting such scheme, because master and slave type castor attaching parts of the present invention comprises female member, sub-member, female member, sub-member is articulated on the adapter shaft, and female member one end is equipped with castor, the other end is the pipe link installation end, sub-member one end is the pipe link installation end, so sub-member, female member can connect a plurality of rod members that can rotate mutually, simple in structure, easy to use, the position of rod member can not influence castor and rotate, because the upper surface of the castor installation end of female member is provided with boss, son, angle between female member is 180 when spending, and female member can prop up the chapelet member by boss.
Description of drawings
Fig. 1 is a kind of constructional drawing that uses state of master and slave type castor attaching parts of the present invention;
Fig. 2 is the constructional drawing of the another kind of use state of master and slave type castor attaching parts of the present invention;
Fig. 3 is the constructional drawing of the sub-member of master and slave type castor attaching parts of the present invention when being three.
The specific embodiment
As Fig. 1, shown in 2, master and slave type castor attaching parts of the present invention, comprise female member 11, sub-member 13, adapter shaft 15, female member 11 1 ends are castor installation end 111, the other end is pipe link installation end 113, on castor installation end 111 end faces castor 12 is installed, pipe link installation end 113 is provided with negative thread and is used for installing head rod, female member 11 middle parts are pin jointed end 115, sub-member 13 1 ends are pipe link installation end 131, the other end is pin jointed end 133, pipe link installation end 131 is provided with negative thread and is used for installing second pipe link, the pin jointed end 115 of female member and the pin jointed end 133 of sub-member all are articulated on the adapter shaft 15, adapter shaft 1 front end is provided with positive stop lug boss 151, the rear end is provided with stop screw 152, be used for the female member of restriction, the axial location of sub-member on adapter shaft 15, the upper surface of the castor installation end 111 of female member 11 is provided with boss 117, when the pipe link installation end 131 of the pipe link installation end 113 of female member and sub-member was on same straight line, boss 117 was resisted against sub-member 13 lower surfaces near pin jointed end 133 positions.
As shown in Figure 3, when group member 13 is three, each sub-member 13 structure is identical, the pin jointed end 133 of each sub-member all is articulated on the adapter shaft 15, when the angle between the pipe link installation end 131 of the pipe link installation end 113 of female member and arbitrary sub-member is 180 when spending, boss 117 is resisted against these sub-member 13 lower surfaces near pin jointed end 133 positions.
