Abstract

A joint structure includes a joint hollow body having a first plate and a second plate arranged opposite to each other, and the second plate has a penetrating hole for defining an axial direction with respect to the penetrating hole, and an external side plate is extended in the defined axial direction from the external periphery of the first plate and connected to the external periphery of the second plate, so as to enhance the structural strength of the joint hollow body and prevent the joint hollow body from having concentrated stress or being cracked easily.

First claim

What is claimed is:

1 . A joint structure, comprising: a joint hollow body, having a first plate and a second plate arranged opposite to each other, and the second plate having a penetrating hole and defining an axial direction with respect to the penetrating hole, wherein an external side plate is extended in the axial direction from the external periphery of the first plate and connected to the external periphery of the second plate.

2 . The joint structure as claimed in claim 1 , further comprising a rotating member, and the rotating member having a rotating shaft, and the rotating member being fixed in the joint hollow body, and the rotating shaft being exposed and protruded out from the penetrating hole.

3 . The joint structure as claimed in claim 2 , wherein the joint hollow body includes a first casing and a second casing engaged with each other, and the first casing includes the first plate and a first external side plate extended from the external periphery of the first plate, and the second casing includes the second plate and a second external side plate extended from the external periphery of the second plate, and the second casing is correspondingly covered onto the first casing, and the second external side plate and the first external side plate are connected with each other to form the external side plate.

4 . The joint structure as claimed in claim 3 , further comprising a plurality of screws, and a plurality of fixing columns jointly extended from the first plate and the first external side plate, and each of the fixing columns having a first fixing hole, and the rotating member having a plurality of second fixing holes, and the screws are passed through and fixed into the second fixing holes and the first fixing holes respectively.

5 . The joint structure as claimed in claim 3 , wherein the first external side plate includes a protruding member extended therefrom, and the second external side plate is installed to the protruding member and latched with the protruding member.

6 . The joint structure as claimed in claim 3 , wherein the first plate has an air hole configured to be opposite to the penetrating hole.

7 . The joint structure as claimed in claim 6 , wherein the first plate includes a first rectangular plate and a first circular plate extended from the top of the first rectangular plate, and the second plate includes a second rectangular plate and a second circular plate extended from the top of the second rectangular plate, and the air hole is formed on the first circular plate, and the penetrating hole is formed on the second circular plate.

8 . The joint structure as claimed in claim 3 , wherein penetrating hole comes with a quantity of two, and the first plate has two air holes configured to be opposite to the two penetrating holes respectively.

9 . The joint structure as claimed in claim 8 , wherein the first plate includes a first rectangular plate and two first circular plates extended from both ends of the first rectangular plate respectively, and the second plate includes a second rectangular plate and two second circular plate extended from both ends of the second rectangular plate, and each air hole is formed on each respective first circular plate, and each penetrating hole is formed on each respective second circular plate.

10 . The joint structure as claimed in claim 9 , further comprising a plurality of screws, a partition plate protruded from the middle of the first rectangular plate, and a plurality of fixing columns jointly extended from the first plate and at least one of the first external side plate and the partition plate, and each fixing column having a first fixing hole, and the rotating member coming with a quantity of two, and each rotating member having a plurality of second fixing holes, and the screws being passed and fixed into the second fixing holes and the first fixing holes respectively.

11 . The joint structure as claimed in claim 3 , wherein the rotating member is a motor, and the motor includes an electric wire, and the first external side plate has a wire passing hole for passing the electric wire.

12 . The joint structure as claimed in claim 11 , further comprising a connecting element and a fixing element, and the rotating shaft having a first through hole, and the connecting element having a second through hole and an annular plate extended from the external periphery of the second through hole, and the fixing element being passed through the first through hole and the second through hole and fixed into the first through hole, and the annular plate being passed into the penetrating hole and rotatable with respect to the penetrating hole.

13 . The joint structure as claimed in claim 3 , wherein the rotating member includes a positioning plate, and the rotating shaft is formed and upwardly extended from the positioning plate.

14 . The joint structure as claimed in claim 13 , further comprising a connecting element and a fixing element, and the rotating shaft having a first through hole, and the connecting element having a second through hole and an annular plate extended from the external periphery of the second through hole, and the fixing element being passed through the first through hole and the second through hole and fixed into the first through hole, and the annular plate being passed through the penetrating hole and rotatable with respect to the penetrating hole.

15 . The joint structure as claimed in claim 3 , further comprising a first assembled member and a second assembled member, and the first assembled member having a first ring plate and a bump extended therefrom, and the first ring plate being passed and connected to the penetrating hole and rotatable with respect to the penetrating hole, and the second assembled member having a second ring plate and a groove, and the second ring plate being passed and connected to the penetrating hole and rotatable with respect to the penetrating hole, and the bump being embeddable into the groove.

16 . The joint structure as claimed in claim 15 , further comprising two fixing elements, and the rotating shaft having a first through hole, and the first assembled member having a third through hole, and the second assembled member having a fourth through hole, and one of the fixing elements being passed through the third through hole and the first through hole and fixed into the first through hole, and the other one of the fixing elements being passed through the fourth through hole and the first through hole and fixed into the first through hole.

17 . The joint structure as claimed in claim 1 , wherein the joint hollow body is manufactured by a 3D printing technology.

18 . The joint structure as claimed in claim 1 , further comprising a third assembled member, a receiving portion disposed at the bottom of the external side plate, and a latch block extended from the receiving portion, and the third assembled member being latched and connected to the latch block.

19 . The joint structure as claimed in claim 1 , further comprising a third assembled member, a receiving portion disposed at the bottom of the external side plate, and a latch groove formed on the receiving portion, and the third assembled member being latched and connected to the latch groove.
