Abstract
A son-mother-type trundle connecting piece comprises a mother component, at least one son component and a connecting shaft. One end of the mother component is a trundle mounting end. The other end of the mother component is a connecting rod mounting end. A trundle is arranged on the end face of the trundle mounting end. A hinged end is arranged in the middle of the mother component. One end of the son component is a connecting rod mounting end. The other end of the son component is a hinged end. The hinged end of the mother component and the hinged end of the son component are both hinged to the connecting shaft which is provided with axial limiting devices used for limiting the positions of the mother component and the son component. A boss is arranged on the upper surface of the trundle mounting end of the mother component. When the included angle between the connecting rod mounting end of the mother component and the connecting rod mounting end of the son component is 180 degrees, the boss abuts against the lower surface of the son component close to the hinged end. According to the son-mother-type trundle connecting piece, a plurality of rod pieces which can rotate relatively can be connected under the situation that the trundle is arranged, when the included angle between the mother component and the son component is 180 degrees, the mother component can support the son component, and structure is simple.
Description
Technical field
The utility model relates to a kind of attaching parts, relates to specifically a kind of attaching parts that castor is installed.
Background technology
The article that formed 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, as the utility application of the application number Multifunctional walking acid that is 201310049906.8, its complex structure, and the rod member angle that castor is installed can affect the rotation of castor while changing.
The utility model content
The purpose of this utility model is to provide a master-slave type castor attaching parts, and it can connect a plurality of relatively turnable rod members in the situation that castor is installed, and the angle between son, female member is 180 while spending, and female member can prop up the chapelet member, simple in structure.
To achieve these goals, technical solution of the present utility model 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 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 adapter shaft, adapter shaft is provided with for limiting female member, 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 while spending, described boss is resisted against sub-member lower surface near the pin jointed end position.
The utility model master and slave type castor attaching parts, 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 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 while spending, boss is resisted against the position of this sub-member lower surface near pin jointed end.
The utility model master and slave type castor attaching parts, 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.
The utility model master and slave type castor attaching parts, wherein, be 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 the utility model master and slave type castor attaching parts comprises female member, sub-member, female member, sub-member is articulated on 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 mutually rotate, simple in structure, 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 member is provided with boss, son, angle between female member is 180 while spending, female member can prop up the chapelet member by boss.
The accompanying drawing explanation
Fig. 1 is a kind of constructional drawing that uses state of the utility model master and slave type castor attaching parts;
Fig. 2 is the constructional drawing of the another kind of use state of the utility model master and slave type castor attaching parts;
Fig. 3 is the constructional drawing of the sub-member of the utility model master and slave type castor attaching parts while being three.
The specific embodiment
As Fig. 1, shown in 2, the utility model master and slave type castor attaching parts, 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 for head rod is installed, 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 for the second pipe link is installed, the pin jointed end 115 of female member and the pin jointed end 133 of sub-member all are articulated 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 member, 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 is on same straight line, boss 117 is 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 structures are identical, the pin jointed end 133 of each sub-member all is articulated on 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 while spending, boss 117 is resisted against these sub-member 13 lower surfaces near pin jointed end 133 positions.
