Description
Technical Field
The utility model relates to the technical field of trundles, in particular to a hexagonal inserted link double-brake wheel.
Background
The caster is a common mechanical hardware fitting, and is usually installed at the bottom of furniture, a cart and other appliances, so that the appliances can be flexibly and conveniently moved. Since the caster needs to be stationary after the implement is moved, the caster generally has a braking function.
The existing caster comprises a caster body, a rotating shaft connected with an appliance is arranged on the caster body, the rotating shaft and the appliance are connected in a direct threaded manner, the installation and the disassembly are convenient, and the wire can be easily moved.
SUMMERY OF THE UTILITY MODEL
In order to achieve the purpose, the utility model adopts the technical scheme that:
a hexagonal inserted bar double-brake wheel comprises a double-brake wheel body, wherein a rotating shaft is arranged in the double-brake wheel body, the top of the wheel body is also provided with a connecting and fixing component, the connecting and fixing component comprises an external thread sleeve and a bolt, and a bolt hole matched with the bolt is formed in the outer surface of the external thread sleeve in the x-axis radial direction and close to the position hole at the bottom of the external thread sleeve;
the part that the pivot is located the double brake wheel body top outside is hexagonal inserted bar, the internal surface of external screw thread cover with it adaptation, and the surface of pivot is located the position in bolt hole and also has seted up the through-hole that uses with the bolt cooperation, logical connect in the utensil bottom with the external screw thread cover, then insert the external screw thread cover with the pivot to finally utilize the bolt to pin, the convenient dismantlement installation can not appear the phenomenon of live silk.
Further, the pivot includes atress portion and direction atress portion, and wherein the diameter of atress portion is greater than the diameter of direction atress portion, avoids the whole atress of pivot and warp, and the atress portion can shorten the stress position and reduce pivot deformation risk.
Furthermore, the top of the guide stress part is connected with a replaceable support pillar in a threaded manner, and the support pillars with different lengths can be replaced by changing the support pillars with different depths of threaded holes matched with the external thread sleeves, so that the whole stress of the rotating shaft is reduced, and the deformation is reduced.
The working principle and the beneficial effects are as follows: through logical the external screw thread cover in the utensil bottom, then insert the external screw thread cover with the pivot to finally utilize the bolt to pin, the convenient dismantlement installation can not appear the phenomenon of live silk.
Drawings
FIG. 1 is a schematic cross-sectional view of the present invention;
FIG. 2 is a schematic structural view of the present invention;
fig. 3 is an assembly schematic of the present invention.
In the figure: 1. a dual brake wheel body; 2. a rotating shaft; 21. a force receiving portion; 22. a guide force-receiving portion; 3. an external thread sleeve; 4. a bolt; 5. a pin hole; 6. and (4) a top pillar.
Detailed Description
The utility model will be better understood from the following examples.
The structures, proportions, and dimensions shown in the drawings and described in the specification are for understanding and reading the present disclosure, and are not intended to limit the scope of the present disclosure, which is defined in the claims, and are not essential to the skilled in the art. In addition, the terms "upper", "lower", "front", "rear" and "middle" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the relative positions may be changed or adjusted without substantial technical changes.
As shown in fig. 1, a hexagonal inserted link double-brake wheel comprises a double-brake wheel body 1, a rotating shaft 2 is arranged in the double-brake wheel body 1, a connecting and fixing component is further arranged at the top of the wheel body 1, the connecting and fixing component comprises an external thread sleeve 3 and a bolt 4, and a bolt hole 5 matched with the bolt 4 is formed in the outer surface of the external thread sleeve 3 in the x-axis direction and close to the position of the bottom of the external thread sleeve;
the part that pivot 2 is located the 1 top outside of dual-brake wheel body is hexagonal inserted bar, and the internal surface of external screw thread cover 3 adapts to it, and the surface of pivot 2 is located the position of bolt hole 5 and also has seted up the through-hole that uses with 4 cooperations of bolt, connects in the utensil bottom with the external screw thread cover logical, then inserts the external screw thread cover with the pivot to finally utilize the bolt to pin, conveniently dismantle the installation, the phenomenon of the silk of can not appearing living.
Wherein, pivot 2 includes atress portion 21 and direction atress portion 22, and wherein the diameter of atress portion 21 is greater than the diameter of direction atress portion 22, avoids the whole atress of pivot and warp, and the atress portion can shorten the atress position and reduce pivot deformation risk.
The top of the guide stress part 22 is also in threaded connection with a replaceable support pillar 6, and due to the fact that the threaded holes formed in the bottom of the tool and matched with the external thread sleeves are different in depth, the support pillars with different lengths can be replaced, the whole rotating shaft is stressed, and deformation is reduced.
