Description

The utility model relates to a lighting and decoration lamp, in particular to a small decorative lamp with a swivel structure used for decoration and festivities.

In foreign countries, Christmas lights have become a must-have decorative light for families. In China, with the improvement of people's living standards and the development of urban nightlife, decorative lights are increasingly used in shops, buildings, tourism, etc. point of decoration as well as family celebration decorations.

Because this kind of decorative lamps are mostly used in clusters, they are large in number and small in size, and the lamp holders are connected by wires. Therefore, the lamp stems are connected with light bulbs, and the lamp stems are directly inserted In the lamp holder, in order to prevent the lamp stem from falling off from the lamp holder, there is a certain tolerance and matching requirement between the lamp holder and the lamp holder. The difference is very large, so it is difficult to meet the requirements for use. Because, in high temperature areas or seasons and when used indoors, the lamp stem will not come out of the lamp holder, but when used outdoors in Christmas or low temperature seasons, the lamp stem will often be damaged due to thermal expansion and contraction. Shedding, coupled with the influence of wind and snow, this kind of shedding often happens. It not only affects the aesthetics and effect of the decoration, but also brings some sense of loss to people's celebration atmosphere after falling.

In addition, since the lamp base and lamp holder of this kind of decorative lamp are all made of plastic injection molding, and they are hung in series or combined to be inserted on the lamp stand to form decorative graphics, it depends on very thin The wires are connected in series and load-bearing. Therefore, the design of the lamp stem and the lamp holder is very thin, and it is easy to become soft when the temperature is high, and it is hard and brittle when the temperature is very low, which is not convenient for the connection between the lamp stem and the lamp holder. The separation is not conducive to the operation of applying force, and it is not convenient to quickly remove and replace the bulb.

In addition, there is no force application point and gap for insertion of hands or tools after the lamp stem and lamp holder of the existing decorative lamp are plugged together. Therefore, it is impossible to quickly and conveniently separate the lamp stem from the lamp holder.

In Taiwan's No. 78210590 patent application, a fastening device for Christmas string light stems and lamp holders is disclosed. In this application, a fastening structure combining buttons and buckles is used to ensure that the lights do not fall off and be disassembled. It is convenient to divide, but because the lamp base and the lamp holder are very small, the buckles and buttons injection molded on them are even smaller.

The purpose of this utility model is to overcome the above-mentioned shortcomings and deficiencies existing in the prior art, and to provide a design with a swivel clamp structure on the lamp stem and the lamp holder, which is convenient for both to be separated and firmly combined. small decorative lights.

The purpose of this utility model is achieved by the following technical scheme, a clamping plate protrudes radially outward on the outer circle of the cylindrical section of the lower part of the flange of the circular lamp pedestal, and is inserted into the lamp holder There is an annular slot in the hole that can be engaged with the clamping plate, and an axial chute that communicates with the annular slot is an axial chute that is open to the opening of the lamp holder. After pressing down the axial chute on the top, the lamp pedestal can be inserted into the inner hole of the lamp holder, and then the lamp pedestal is rotated axially, and the clamping plate is inserted into the annular slot in the inner hole of the lamp holder. To pull out the lamp stem, you only need to repeat the above actions in reverse.

As can be seen from the above, the remarkable effect of the present utility model is:

The ingenious design of the first clip board and the ring-shaped slot not only ensures that the lamp stem and the lamp holder are firmly combined and cannot fall off at will, but also allows the two to be separated easily as needed, especially for the replacement of the bulb. The utility model has the characteristics of simple structure, convenience and practicality.

The flange at the hole on the second pedestal facilitates the application of force by hand or tool.

Concrete structure of the present utility model is realized by following embodiment and accompanying drawing 1 thereof:

The concrete structure of the present utility model will be described in detail below in conjunction with accompanying drawing 1:

The utility model is composed of a bulb 1, a lamp base 2 and a lamp holder 3. The bulb 1 is inserted into the inner hole of the lamp base 2, and the lamp base 2 is inserted into the inner hole 3a of the lamp holder 3. It is characterized in that: the lamp base 2 There is a clamping plate 2b that protrudes radially outward on the outer circle of the cylinder section in the middle section. In the inner hole 3a of the lamp holder 3, there is an annular clamping groove 3c that is rotated with the clamping plate 2b on the lamp stem 2, and is connected with the circular clamping groove. 3c is connected to a chute 3b with an open opening along the axial direction of the inner hole 3a, and there is an annular flange 2a on the upper edge of the inner hole of the lamp stem 2.

The utility model is characterized in that:

The clamping plate 2b protrudes outward in the axial middle of the cylindrical section of the lamp base 2, the clamping plate 2b is in the shape of an arcuate plate and is perpendicular to the outer surface of the cylindrical section, and is horizontally convex. The bending curvature of the clamping plate 2b is the same as that of the cylindrical section. The groove 3c is located in the middle and upper part of the inner hole 3a of the lamp holder 3, and the concave depth of the annular groove 3c and the chute 3b connected with the annular groove 3c is the same as or greater than the horizontal convex thickness of the clamping plate 2b.

The utility model is characterized in that:

The chute 3b communicates with the annular slot 3c in the circumferential direction and is perpendicular to the annular slot 3c. The outer arc surface of the bow-shaped clamping plate on the lamp stem 2 is an n-shaped arc surface, and the flange on the upper edge of the inner hole of the lamp stem 2 2a is in the shape of a ring platform, and the diameter of its convex outer ring is larger than the outer diameter of its lower cylindrical section.

The use process of the utility model is that when inserting the lamp pedestal into the inner hole of the lamp holder, first align the clamping plate 2b with the chute 3b, and then push the flange 2a until the lower edge of the clamping plate is caught by the lower edge of the annular clamping groove 3c , at this time, you can turn the lamp stem 2 so that the upper clamping plate is turned into the annular groove 3c, so that the lamp stem and the lamp holder are firmly combined and cannot be disengaged at will. If the lamp stem and the lamp holder need to be separated, Then reversely turn the card plate on the lamp base to the chute, and then pull it out upwards.
