Abstract
Connection structure of outer and inner bowls of plastic trundle is provided. The trundle has outer and inner bowls. The inner bowl is arranged below the outer bowl, and a cog is arranged on lower end surface of the inner bowl. The utility model is characterized in that the lower end surface of the outer bowl has a bump. The upper end surface of the inner bowl has a bump too. The upper end surface of the bump has a meshed tooth. The meshed tooth on the lower end surface of the outer bowl and that of the inner bowl are meshed from each other. The inner and outer bowls are fastened together by plastic bolt. The meshed teeth on the lower end surface of the bump of the outer bowl are distributed evenly around the bump. The meshed teeth on the upper end surface of the bump of the inner bowl are distributed evenly around the bump, too. The inner and outer bowls of the utility model are fixedly connected by plastic bolt, which is convenient to assemble the trundle and solves problem that the rivet rusts in plastic trundle by former connection way.
Description
Technical field
The utility model relates to a kind of structure of castor, the connection structure of outer bowl of particularly a kind of plastics castor and interior bowl.
Background technology
Being connected and fixed by the riveted joint of metal rivet flange between the interior bowl of existing plastic caster wheel and the outer bowl, but the metal rivet cost is higher, also takes a lot of work during riveted joint, and easily get rusty.
Summary of the invention
The utility model provides the syndeton of the outer bowl of a kind of plastic caster wheel and interior bowl, and purpose is to solve the prior art problem, and a kind of new outer bowl and the syndeton of interior bowl are provided, and making when bowl is connected with outer bowl in it does not need metal rivet firmly to link together.
The utility model technical scheme that adopts of dealing with problems is:
The connection structure of outer bowl of plastics castor and interior bowl, bowl and outer bowl in castor has, interior bowl is located at outer bowl below, and interior bowl lower surface offers teeth.It is characterized in that: the lower surface of described outer bowl has boss, and the lower surface of boss has grinding tooth.The upper surface of interior bowl also has boss, and the boss upper surface has grinding tooth, and the grinding tooth of the grinding tooth of outer bowl boss lower surface and interior bowl boss upper surface can be meshing with each other.Outer bowl is in the same place by bolted with interior bowl.
Grinding tooth on the lower surface of described outer bowl boss is evenly distributed on one week of boss.
Grinding tooth on the upper surface of described interior bowl boss is evenly distributed on one week of boss.
Described bolt is a plastic bolt.
The beneficial effects of the utility model: outer bowl and interior bowl in the utility model are connected and fixed by plastic bolt, have both made things convenient for the assembling of castor, have solved again the problem that rivet gets rusty in the former connected mode of plastic caster wheel.And on interior bowl and outer bowl of contacted end face, have respectively grinding tooth, make interior bowl and intermeshing being in the same place of outer bowl energy, both are fastened together, be difficult for becoming flexible, affect the normal use of castor.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cut-away view of outer bowl;
Fig. 3 is the upward view of outer bowl;
Fig. 4 is the cut-away view of interior bowl;
Fig. 5 is the diagrammatic sketch of bowing of interior bowl;
Fig. 6 is the upward view of interior bowl.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, the bindiny mechanism of outer bowl of plastics castor and interior bowl, support 1 lower end is provided with wheel 2, and the upper end is set in outside bearing 3 outer rings.Outer bowl 4 is set in bearing 3 inner rings, and interior bowl 5 is located at outer bowl 4 belows, and interior bowl 5 lower surfaces offer teeth 52.Brake handle 7 is hinged on support 1 one sides, brake facing 6 is fixed on support 1 inboard by bearing pin, its brake facing 6 one ends are positioned at bowl 5 belows, the other end is positioned at brake handle 7 belows, the end that brake facing 6 is positioned at bowl 5 belows has gear ring 8, the upper surface of gear ring 8 offers teeth 81, and these teeth 81 can be meshing with each other with the teeth 52 on interior bowl 5 lower surfaces.Described outer bowl 4 centers have axis hole 42, and the lower surface of outer bowl 4 has boss 41, and the lower surface of boss 41 has grinding tooth 411, and grinding tooth 411 is evenly distributed on 41 1 weeks of boss.The upper surface of interior bowl 5 also has boss 51, and boss 51 upper surfaces have grinding tooth 511, and grinding tooth 511 is evenly distributed on 51 1 weeks of boss, and the grinding tooth 511 of the grinding tooth 411 of outer bowl boss 41 lower surfaces and interior bowl boss 51 upper surfaces can be meshing with each other.Outer bowl 4 and interior bowl 5 tighten together by plastic bolt 9.
When stopping direction, the end that brake facing 6 has gear ring 8 upwarps, and the other end presses down, but pressure side does not contact with wheel 2 down.Teeth 52 on teeth 81 on its gear ring 8 and interior bowl 5 lower surfaces are meshed, brake block 6 can not be rotated along the axis of axis hole 42 and interior bowl 5, because brake block 6 is connected connections with support, support 1 can not be rotated along the axis of axis hole 42 and interior bowl 5, thus the function of the direction that realized stopping.During brake wheel, 6 times pressure sides of brake facing contact with wheel 2, make wheel 2 fixing, and bolt 9 contacts with wheel 2 at this moment.
Outer bowl and interior bowl in the utility model are connected and fixed by plastic bolt, have both made things convenient for the assembling of castor, have solved again the problem that rivet gets rusty in the former connected mode of plastic caster wheel.And on interior bowl and outer bowl of contacted end face, have respectively grinding tooth, make interior bowl and intermeshing being in the same place of outer bowl energy, both are fastened together, be difficult for becoming flexible, affect the normal use of castor.
