Abstract

A magnetic rack including a casing formed with an internal receiving chamber in which a magnetic unit is received. The magnetic unit is composed of a magnet and two iron strips respectively attracted by and attached to two sides of the magnet. Each iron strip has a projecting section protruding from the magnet. The top face of the receiving chamber is formed with a slit corresponding to each projecting section of the iron strip, whereby only the projecting section of the iron strip outward protrudes from the casing. A bottom board is disposed on bottom face of the casing for enclosing and fixing the magnetic unit in the receiving chamber of the casing.

Claims

1. A magnetic rack comprising a casing formed with over one internal receiving chamber in which a magnetic unit is received, the magnetic unit being composed of a magnet and two iron strips respectively attracted by and attached to two sides of the magnet, each iron strip having a projecting section protruding from the magnet, each projecting section having over one notch, the receiving chamber being formed with a slit corresponding to each projecting section of the iron strip, whereby only the projecting section of the iron strip outward protrudes from the casing, a bottom board being disposed on bottom face of the casing for enclosing and fixing the magnetic unit.

2. A magnetic rack as claimed in claim 1, wherein the casing and the bottom board are formed with multiple corresponding through holes for bolts to pass therethrough and lock the magnetic rack on a fixed article.

3. A magnetic rack as claimed in claim 1, wherein the bottom board is fused on the bottom face of the casing by ultrasonic wave.

4. A magnetic rack as claimed in claim 1, wherein multiple non-magnetic pins are passed through the magnet and the iron strips of the magnetic unit.

5. A magnetic rack as claimed in claim 1, wherein the projecting section of the iron strip is waved.

6. A magnetic rack as claimed in claim 2, wherein the through holes on two sides of the bottom board are formed with recessed sections in which two hook sections of an article bracket are inlaid, bolts being passed through the through holes and the hook sections to lock the magnetic rack on a fixed article.

7. A magnetic rack as claimed in claim 1, wherein one side of the bottom board. is formed with multiple trumpet holes opposite to the casing, a sucker being disposed in each trumpet hole, the sucker being integrally formed with a thread section passing through the trumpet hole and extending to the casing, the casing being disposed with multiple nuts respectively screwed on the thread sections of the suckers, an inner diameter of the trumpet hole being smaller than the diameter of the sucker, whereby when turning the nut to drive the thread section of the sucker to move toward the casing, a projecting edge of the trumpet hole will abut against the sucker.

8. A magnetic rack as claimed in claim 1, wherein the casing is composed of a front cover and a rear cover symmetrical to each other, each of the front and rear covers being formed with a receiving chamber in which a magnetic unit is received, whereby the projecting sections of the magnetic units protrude from both the front and rear sides of the casing.

9. A magnetic rack as claimed in claim 8, wherein a pad member is disposed between the two magnetic units received in the receiving chambers of the front and rear covers for isolating the two magnetic units from each other.
