Abstract

A magnetic rack, conveying truck and corresponding conveyor. The magnetic rack includes: a body on which a groove is disposed; at least one magnetic brick on which a first contact part is disposed, the magnetic brick being located in the groove; and a cover which is placed over the groove so as to partially cover the groove, a second contact part and at least one hole being disposed on the cover, the first contact part being contact with the second contact part to fix the magnetic brick in the groove, the at least one hole being used for exposing the at least one magnetic brick.

First claim

The invention claimed is:

1. A magnetic rack, comprising:
a body on which a groove is disposed;
at least one magnetic brick having a first contact part, the brick being located in the groove; and
a cover having a second contact part and at least one hole, the cover being placed over the groove so as to partially cover the groove, the first contact part being in contact with the second contact part to fix the magnetic brick in the groove, the at least one hole being used for exposing the at least one magnetic brick.

2. The magnetic rack according to claim 1 , wherein the first contact part takes a convex shape and is located at an end of the magnetic brick.

3. The magnetic rack according to claim 2 , wherein the first contact part is located at a position on the magnetic brick which is close to the groove.

4. The magnetic rack according to claim 2 , wherein the first contact part is located at a middle position on the magnetic brick along a depth direction of the groove.

5. The magnetic rack according to claim 1 wherein the first contact part is a slope at a certain angle with a plane where the bottom of the groove is located, the slope being located at an end of the magnetic brick.

6. The magnetic rack according to claim 1 , further comprising:
a cushion which is located between the magnetic brick and the groove.

7. The magnetic rack according to claim 1 , wherein the cover is fixed on the body by a screw.

8. A conveying truck, comprising a truck body and wheels, further comprising:
magnetic rack according to claim 1 , which is located at the bottom of the truck body.

9. The conveying truck according to claim 8 , further comprising:
an adjuster which is located between the truck body and the magnetic rack, for adjusting spacing between the truck body and the magnetic rack.

10. The conveying truck according to claim 9 , wherein the adjuster is an adjustable screw.

11. The conveying truck according to claim 9 , further comprising:
a fastening screw for fixing the magnetic rack at the truck body when the spacing between the truck body and the magnetic rack has been adjusted to an expected value.

12. A conveyor comprising a magnetic gear that is rotatable around a shaft, comprising:
a conveying truck according to claim 9 , the magnetic gear driving the magnetic rack through magnetic gearing.

13. The conveyor according to claim 12 , wherein the adjuster is an adjustable screw.

14. The conveyor according to 12 , further comprising:
a fastening screw for fixing the magnetic rack at the truck body when the spacing between the truck body and the magnetic rack has been adjusted to an expected value.

15. The conveying truck according to claim 9 , further comprising:
a fastening screw for fixing the magnetic rack at the truck body when the spacing between the truck body and the magnetic rack has been adjusted to an expected value.

16. The conveying truck according to claim 8 , wherein the first contact part takes a convex shape and is located at an end of the magnetic brick.

17. The conveying truck according to claim 16 , wherein the first contact part is located at a position on the magnetic brick which is close to the groove.

18. The conveying truck according to claim 16 , wherein the first contact part is located at a middle position on the magnetic brick along a depth direction of the groove.

19. The conveying truck according to claim 8 , wherein the first contact part is a slope at a certain angle with a plane where the bottom of the groove is located, the slope being located at an end of the magnetic brick.

20. The conveyor truck according to claim 8 , further comprising:
a cushion which is located between the magnetic brick and the groove.
