1. Field of the Invention
The present invention relates to a hanging chain structure for a pendent lamp, and more particularly to a hanging chain structure which is combined with the pendent lamp easily and rapidly, thereby facilitating the operator mounting the pendent lamp.
2. Description of the Related Art
A conventional hanging chain structure 2 in accordance with the prior art shown in
However, the hanging rings 21 are not connected easily and rapidly, so that the conventional hanging chain structure is not assembled easily and rapidly, thereby causing inconvenience to the operator when mounting the hanging chain structure. In addition, the conventional hanging chain structure 2 is not combined with the pendent lamp 3 and the ceiling 1 easily and rapidly, thereby causing inconvenience to the operator when mounting the pendent lamp 3 to the ceiling 1. Further, the hanging rings 21 are not connected with each other rigidly and stably, thereby easily affecting connection between the conventional hanging chain structure 2 and the pendent lamp 3.
The primary objective of the present invention is to provide a hanging chain structure which is combined with the pendent lamp and the ceiling easily and rapidly, thereby facilitating the operator mounting the pendent lamp to the ceiling.
Another objective of the present invention is to provide a hanging chain structure, wherein the hanging rings are connected rapidly, so that the hanging chain structure is assembled easily and rapidly, thereby facilitating the operator mounting the hanging chain structure.
A further objective of the present invention is to provide a hanging chain structure, wherein the hanging rings are connected with each other rigidly and stably without detachment.
In accordance with the present invention, there is provided a hanging chain structure, comprising a plurality of hanging rings connected with each other, each of the hanging rings including a hook body, and a stop member pivotally mounted on the hook body, wherein:
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
Referring to the drawings and initially to
The ceiling 4 is provided with a fixing hook 41 locked on the uppermost one of the hanging rings 51, and the pendent lamp 6 is provided with a fixing hook 61 locked on the lowermost one of the hanging rings 51.
Each of the hanging rings 51 of the hanging chain structure 5 includes a hook body 511, and a stop member 512 pivotally mounted on the hook body 511. The hook body 511 of each of the hanging rings 51 is substantially C-shaped, and has a first end formed with a pivot seat 5113 and a second end formed with a locking block 5111. The locking block 5111 of the hook body 511 is formed with a locking recess 5112. The pivot seat 5113 of the hook body 511 is formed with a pivot hole 5114 and has a periphery formed with a limiting notch 5115.
The stop member 512 of each of the hanging rings 51 is substantially rod-shaped, and has a first end pivotally mounted on the pivot seat 5113 of the hook body 511 and a second end provided with a retaining pin 51260 inserted into and locked in the locking recess 5112 of the locking block 5111 of the hook body 511.
The first end of the stop member 512 is formed with a passage hole 5123 aligning with the pivot hole 5114 of the pivot seat 5113. Each of the hanging rings 51 of the hanging chain structure 5 further includes a pivot pin 5122 extended through the passage hole 5123 of the stop member 512 and the pivot hole 5114 of the pivot seat 5113, so that the first end of the stop member 512 is pivotally mounted on the pivot seat 5113 of the hook body 511. The first end of the stop member 512 is formed with a receiving recess 5121 for receiving the pivot seat 5113 of the hook body 511.
The second end of the stop member 512 is formed with a passage hole 5129 for passage of the retaining pin 51260. The second end of the stop member 512 is formed with a receiving recess 5127 for receiving the locking block 5111 of the hook body 511 when the retaining pin 51260 is inserted into the locking recess 5112 of the locking block 5111.
The stop member 512 of each of the hanging rings 51 has an inside formed with a receiving chamber 5124. Each of the hanging rings 51 of the hanging chain structure 5 further includes an elastic plate 5126 mounted in the receiving chamber 5124 of the stop member 512 and having a distal end 51260 extended into and locked in the limiting notch 5115 of the pivot seat 5113, and a spring 5125 mounted in the receiving chamber 5124 of the stop member 512 and having a first end urged on a wall of the receiving chamber 5124 of the stop member 512 and a second end urged on the elastic plate 5126.
In operation, referring to
After the force applied on the stop member 512 is removed, the stop member 512 is pivoted relative to the pivot seat 5113 of the hook body 511 by the restoring force of the distal end 51260 of the elastic plate 5126 to return to the original position as shown in
In such a manner, the hook body 511 of a first hanging ring 51 is pressed on the stop member 512 of a second hanging ring 51 to pivot the stop member 512 of the second hanging ring 51 to form the gap, so that the hook body 511 of the first hanging ring 51 is inserted into and connected with the hook body 511 of the second hanging ring 51. Then, the stop member 512 of a second hanging ring 51 is returned to the original position by the restoring force of the elastic plate 5126, so that the hook bodies 511 of the hanging rings 51 are connected with each other.
Accordingly, the hanging rings 51 are connected with each other easily and rapidly, so that the hanging chain structure 5 is assembled easily and rapidly, thereby facilitating the operator mounting the hanging chain structure 5. In addition, the hanging chain structure 5 is combined with the pendent lamp 6 and the ceiling 4 easily and rapidly, thereby facilitating the operator mounting the pendent lamp 6 to the ceiling 4. Further, the retaining pin 51260 is locked in the locking recess 5112 of the locking block 5111 by the elastic force of the elastic plate 5126, thereby locking the stop member 512 on the hook body 511 to form a closed hanging ring 51, so that the hanging rings 51 are connected with each other rigidly and stably without detachment.
Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
