Connecting device

Abstract

A joining device is provided for connecting a plurality of rods. The joining device includes a plurality of joining tubes and a connector. Each joining tube defines a channel through which one of the rods passes. Each joining tube includes a first outer wall surface, a mounting groove formed on the first outer wall surface, a second outer wall surface, and an insert groove formed on the second outer wall surface. The connector includes a base portion for detachably mounting in the mounting groove of one of the joining tubes, and a slider portion for detachably mounting in the insert groove of another joining tube. By detachably mounting the connector in one joining tube and detachably mounting it in another joining tube, the joining tubes can be assembled according to various combination requirements, achieving the effects of reducing manufacturing and material costs and flexible application.

Claims

1. A joining device suitable for connecting a plurality of rods, the joining device comprising: a plurality of joining tubes, each joining tube extending along an axis and defining a channel extending along the axis and adapted for through which one of the rods passes, each joining tube including a first outer wall surface, a mounting groove formed on the first outer wall surface, a second outer wall surface, and an insert groove formed on the second outer wall surface and extending along the axis; and a connector for connecting the joining tubes, including a base portion for detachably disposed in the mounting groove of one of the joining tubes, and a slider portion connecting the base portion, the slider portion being detachably disposed in the insert groove of another joining tube.

2. The coupling device as claimed in claim 1, wherein, The extended plane of the first outer wall intersects with the extended plane of the second outer wall.

3. The coupling device as claimed in claim 1, wherein, The slider extends along an embedding direction intersecting the extension direction of the base portion. When the base portion is disposed in the mounting groove of one of the connecting pipes, the extension direction of the base portion is the same as the extension direction of the axis of one of the connecting pipes. When the slider portion is slidably disposed in the embedding groove of another connecting pipe along the embedding direction, the embedding direction is the same as the axial direction of the other connecting pipe.

4. The coupling device as claimed in claim 1, wherein, The connector includes a plurality of the slider portions, which are spaced apart along the extending direction of the base portion.

5. The coupling device as claimed in claim 4 further includes a plurality of locking fasteners, each of the coupling tubes further including a groove bottom surface defining the bottom of the mounting groove, and a plurality of screw holes formed in the groove bottom surface, the connector further including a plurality of locking holes spaced apart from the slider portions along the extension direction of the base portion, the locking holes penetrating the slider portions and the base portion, each of the locking fasteners being screwed into one of the screw holes through one of the locking holes.

6. The coupling device as claimed in claim 5, wherein, The two connecting pipes are connected along the axis. The two ends of the base portion are also detachably provided with mounting grooves in the two connecting pipes respectively. The locking holes correspond to the screw holes in the two connecting pipes respectively, and are locked by the locking fasteners to lock the connector to the two connecting pipes.

7. The joining device as claimed in claim 1 further includes a limiting member, the limiting member including a first substrate and a second substrate connected at an angle, a protrusion disposed on the first substrate, a groove formed on the second substrate, and two through holes, wherein one through hole passes through the first substrate and the protrusion, and the other through hole passes through the second substrate and communicates with the groove, the protrusion being detachably disposed in the mounting groove of one of the joining pipes, and the groove being detachably embedded in the slider portion of the connector.

8. The joining device as claimed in claim 1, comprising three joining pipes and three connecting members, wherein the axes of the joining pipes are perpendicular to each other, and the mounting groove of each joining pipe is disposed toward the embedding groove of another joining pipe, the base portion of each connecting member is disposed in the mounting groove of one of the joining pipes, and the slider portion is disposed in the embedding groove of an adjacent joining pipe.

9. The coupling device as claimed in claim 1, wherein, The channel has a rectangular cross-section along the extension direction of the axis, and the first outer wall surface is connected to the second outer wall surface.

10. The coupling device as claimed in claim 1, wherein, These inlay slots are dovetail slots.
