Abstract

The present application provides a hub holding apparatus, including: a base on which a mounting hole and a receiving cavity are disposed, a center line of the mounting hole being perpendicular to a center line of the receiving cavity, and the mounting hole being in communication with the receiving cavity; a screw rotatable relative to the base; a first nut sleeved on the first threaded portion and received in the receiving cavity; and a second nut sleeved on the second threaded portion and received in the receiving cavity.

First claim

What is claimed is:

1. A hub holding apparatus, comprising:
a base on which a mounting hole and a receiving cavity are disposed, a center line of the mounting hole being perpendicular to a center line of the receiving cavity, and the mounting hole being in communication with the receiving cavity;
a screw rotatable relative to the base, the screw comprising a first threaded portion and a second threaded portion, one end of the first threaded portion being fixedly connected to one end of the second threaded portion, and both the first threaded portion and the second threaded portion being received in the receiving cavity, a thread of the first threaded portion being disposed along a first rotation direction, and a thread of the second threaded portion being disposed along a second rotation direction, the first rotation direction and the second rotation direction being opposite to each other;
a first nut sleeved on the first threaded portion and received in the receiving cavity; and
a second nut sleeved on the second threaded portion and received in the receiving cavity.

2. The hub holding apparatus according to claim 1 , wherein
a thread pitch of the thread of the first threaded portion is equal to a thread pitch of the thread of the second threaded portion.

3. The hub holding apparatus according to claim 1 , wherein
the first nut has a first thread disposed along the first rotation direction; and
the second nut has a second thread disposed along the second rotation direction.

4. The hub holding apparatus according to claim 1 , wherein
the screw further comprises a connecting portion and a handle, another end of the second threaded portion being fixedly connected to one end of the connecting portion, and the handle being fixed to another end of the connecting portion.

5. The hub holding apparatus according to claim 4 , wherein
the hub holding apparatus further comprises a first baffle plate and a second baffle plate, the first baffle plate being disposed at another end of the first threaded portion, and the second baffle plate being disposed at the another end of the second threaded portion.

6. The hub holding apparatus according to claim 1 , wherein
a limiting block is disposed on each of the first nut and the second nut, and a limiting groove is disposed on an inner side surface of the receiving cavity, a center line of the limiting groove being parallel to a center line of the receiving cavity; and
the limiting block of the first nut and the limiting block of the second nut are both embedded in the limiting groove and are slidable in the limiting groove.

7. The hub holding apparatus according to claim 1 , wherein
the first nut and the second nut are both hexagon nuts, and a cross-sectional shape of the receiving cavity is a hexagon.

8. The hub holding apparatus according to claim 1 , wherein
the hub holding apparatus further comprises a bracket, wherein the base is fixed to the bracket, and the bracket may be mounted at a hub.

9. The hub holding apparatus according to claim 8 , wherein
the bracket comprises a first mounting portion, a second mounting portion, a connecting rod, and a threaded rod; wherein
there are two connecting rods, one end of one of the connecting rods being fixedly connected to one end of the other of the connecting rods via a first fixed plate, and another end of one of the connecting rods being fixedly connected to another end of the other of the connecting rods via a second fixed plate:
the first mounting portion is sleeved on one end of each of the two connecting rods respectively and may slide on the two connecting rods;
the second mounting portion is sleeved on the another end of each of the two connecting rods respectively and may slide on the two connecting rods; and
the threaded rod is rotatably connected to the first mounting portion and the second mounting portion.

10. The hub holding apparatus according to claim 9 , wherein
a rotational handle is disposed on one end of the threaded rod, wherein rotating the rotational handle drive the threaded rod to rotate, and during the rotation, the first mounting portion and the second mounting portion approach to or move away from each other along the two connecting rods.

11. A hub holding apparatus, comprising:
a base on which a mounting hole and a receiving cavity are disposed, a center line of the mounting hole being perpendicular to a center line of the receiving cavity, and the mounting hole being in communication with the receiving cavity; and
a screw rotatable relative to the base, the screw comprising a first threaded portion and a second threaded portion, one end of the first threaded portion being fixedly connected to one end of the second threaded portion, and both the first threaded portion and the second threaded portion being received in the receiving cavity, a thread of the first threaded portion being disposed along a first rotation direction, and a thread of the second threaded portion being disposed along a second rotation direction, the first rotation direction and the second rotation direction being opposite to each other;
wherein a thread pitch of the thread of the first threaded portion is equal to a thread pitch of the thread of the second threaded portion.

12. The hub holding apparatus according to claim 11 , further comprising:
a first nut sleeved on the first threaded portion and received in the receiving cavity.

13. The hub holding apparatus according to claim 12 , further comprising:
a second nut sleeved on the second threaded portion and received in the receiving cavity.

14. The hub holding apparatus according to claim 13 , wherein
the first nut has a first thread disposed along the first rotation direction; and
the second nut has a second thread disposed along the second rotation direction.

15. The hub holding apparatus according to claim 11 , wherein
the screw further comprises a connecting portion and a handle, another end of the second threaded portion being fixedly connected to one end of the connecting portion, and the handle being fixed to another end of the connecting portion.

16. The hub holding apparatus according to claim 15 , further comprises a first baffle plate and a second baffle plate, the first baffle plate being disposed at another end of the first threaded portion, and the second baffle plate being disposed at the another end of the second threaded portion.

17. A hub holding apparatus, comprising:
a base on which a mounting hole and a receiving cavity are disposed, a center line of the mounting hole being perpendicular to a center line of the receiving cavity, and the mounting hole being in communication with the receiving cavity;
a screw rotatable relative to the base, the screw comprising a first threaded portion and a second threaded portion, one end of the first threaded portion being fixedly connected to one end of the second threaded portion, and both the first threaded portion and the second threaded portion being received in the receiving cavity, a thread of the first threaded portion being disposed along a first rotation direction, and a thread of the second threaded portion being disposed along a second rotation direction, the first rotation direction and the second rotation direction being opposite to each other.
