Quick connection lamppost

A lamp base has a lamppost and a base. One end of the lamppost has a connection element and the base has a connection component that corresponds to a connection element. The lamp base is assembled in sequence, with first the lamppost, the connection piece, the insulation piece and then contact points. Inside the lamppost are electrical wires connected to the contact points.

FIELD OF THE INVENTION

This invention involves lamps and specifically a kind of lamp base that can be dissembled.

DISCUSSION OF RELATED ART

The construction shown inFIG. 1is the kind of lamppost connection1that is most commonly seen in floor lamps or similar lamps on the market at this time. Lamppost2and lamppost3are joined together by a connector4with screw threads; electrical wires5pass through the hollow chambers in the middle of the posts thereby allowing passage from the electricity source end6to the load end7.

Because the electrical wires5must pass through lamppost2, the connector4, and lamppost3, when a consumer connects the lampposts1he needs to pull the wires5and turn the lampposts2and3(turning over five revolutions) in order to accomplish the assembly. As a result, the wires5are often damaged unintentionally, thereby leading to short-circuit [leakage] and hazards. Although the lampposts may be disassembled for shipping, the wires within cannot be removed. The wires are pulled and shuffled during packing, which creates a potential hazard. Furthermore, packing is difficult because of the bulky size.

With the current lamp connectionFIG. 1, a lamppost passes through a hole in the base and the lamppost is locked tight with a screw on the inside of the base. However, because the lamppost and the base are attached with a screw, they may not be taken apart easily, which results in bulky volume for shipping, higher costs for shipping, and ultimately higher prices when the consumer buys the lamp. Also, when the consumer hangs the lamp, he needs to hang the entire lamp to the ceiling; because of the heavier weight of the lamp, potential hazards exist in the hanging process. When problems occur to the lamp, the consumer has to take the entire lamp down from the ceiling in order to perform maintenance or repair, which is very inconvenient.

SUMMARY OF THE INVENTION

This practical new design involves a lamp base, the characteristics of which are that: One end of the lamppost has a connection element; the base has a connection component that matches said connection element. When used, the connection element that is at one end of the lamppost of this new design is inserted through a hole on the base; its raised point is lined up with the notch on the connection component; the connection element is rotated to lock the raised point into the notch; and then, the lamppost ring is twisted tight so that the lamppost is securely attached to the base. This kind of lamppost and lamp base can be assembled and disassembled very easily, furthermore, the lamppost and the base can be packed separately for shipping; by so doing, the costs of shipping and packing are greatly reduced and resources are saved. At the same time, the consumer can hang the base of the lamp on the ceiling first, and then connect the lampposts one by one easily and safely.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The goal of the practical new design is to provide an improved lamp base that could cure certain shortcomings of awkward installation and removal of lamppost and base that are involved with the current technique. To realize the above goal, the strategy of this invention is: A type of lamp base made principally of the lamp post(s) and the base. Its characteristics are that a connection element is attached to one end of the lamppost. A connection component that matches this connection element is attached to the base.

When used, the connection element on one end of this design is passed through a hole in the base, the raised point on the connection element is lined up with the notch on the connection component, the connection element is rotated so that the raised point locks into the notch, and then the lamp post ring is turned tight so as to affix the lamp post firmly to the base; the assembling and disassembling of this kind of lamp post and base are very easy; also, because the lamppost and the base can be packed separately for shipping, the costs of shipping and packing are greatly reduced and resources are conserved. At the same time, when hanging the lamp, one can hang the base of the lamp to the ceiling first, and then connect the lampposts one by one, which would be easy and safe.

FIG. 2shows an exploded view of the parts including lamp post11, electrical wires12, connector13, connector14, contact point, springs16, insulation piece17, screw18, and lamp post19.

FIG. 3,4,5shows the assembly method. Assemble11,12,13in the above picture into sub-assembly20as shown; and assemble14,15,16,17,18,19into sub-assembly21. As shown, horizontally insert sub-assembly21into the component13of sub-assembly20. Make sure that the raised point P on the component14of sub-assembly21is lined up with the notch N on the component13of sub-assembly20, and then, rotate sub-assembly20along the center axis by 30°; the contact points on the component15of sub-assembly21would precisely come into contact with the contact points on the component12of sub-assembly20thereby allowing electricity current to pass through. In this stage, the function of the springs16is to secure the points of contact.

As seen inFIG. 6,7,8, this invention consists principally of the lamppost101and base120. Its characteristics are: A connection element100is set at one end of the lamppost; a connection component100athat matches this connection element is set in the base. The connection element is made by connecting together, in sequence, lamp post ring103, connection component104, insulation piece105, and contact points106; inside the lamp post are electrical wires102, the electrical wires are connected to the contact points106. The connection component is made by connecting together, in sequence, contract points107, an insulation piece108, springs109, and the wire connector111. Inside the connection component are electrical wires112, one end of the wires is connected to the contact points107. The other end of the wires is connected to the connection component. On the connection element is a raised point114. On the connection component is a notch115that matches the raised point, said notch is in the shape of a hook. On the connection component are two connection pieces; on each of the connection pieces is a screw hole; the connection pieces are affixed to the base by a screw113; the base is in the shape of a disk. On the side of the disk are a certain number of small holes; its diameter is larger than the diameter of the insertion device.

At time of assembly, pass the connection element100through a hole116in the base. Line up the raised point114on the connection element100with the notch115on the connection component100a. Rotate the connection element toward the connection component by 30 degrees. Release the hands and the springs109. The connection component100awill push the raised point114into the notch115. Because the notch115is the shape of an upside-down hook, the raised point114is locked inside the notch155. Next, turn the screw threads on the lamppost that wrap around the insulation piece in clockwise direction and lock it tight. At this point, the installation of a single lamppost to the base is complete. If the lamp has multiple lampposts, repeat the preceding installation steps.

ADVANTAGES OF THE INVENTION

The various parts of the lamps that use this technology for connection can be packed completely separately, which can reduce the cost of packing the products to the maximum. The electrical wires are connected only in the enclosed lamppost units. The electrical wires are not visible on the outside. The rotation during assembly has nothing to do with the electrical wires. The electrical wires would not be damaged from scraping. As a result, it is safer than the current technique. When assembling the lamp, a consumer needs only to perform the actions of insertion and rotation, which makes it easy and safe for the consumer. It is common knowledge that electrical wires are polarity specific. In the event the polarities are mixed up during assembly, hazards may be created. The raised point and notch design that is shown in the partial view ensures the differentiation of the polarities of the electrical wires thereby preventing the potential hazards that is produced by reversed polarity in connection.
