Description

folding table lamp

technical field

The invention relates to a foldable table lamp. Through the rotation and folding of each component, the lamp head device is not only protected from collision damage, but also the structure of the table lamp can be stretched and contracted, and the practical function of small-volume storage and unfolding of the product is realized.

Background technique

In today's market, in order to meet the needs of people's daily work and life, table lamps of various forms emerge in endlessly, but due to the size problem, it causes inconvenience to transportation, and the lamp head of the table lamp is easily damaged. Ordinary incandescent lamps and energy-saving lamps are broken and produce fragments. Big security risk. In recent years, as semiconductor lighting has penetrated into all aspects of life, the design of desk lamps has become more diversified, making it inevitable to develop foldable desk lamps that are compact, flexible, easy to carry, easy to operate, and beautiful in appearance.

Contents of the invention

The object of the present invention is to provide a foldable desk lamp for the defects of the prior art. By rotating the four parts of the desk lamp, the folding and stretching of the desk lamp can be realized, which is easy to carry and operate.

As a form of desk lamp design, retractable and foldable desk lamps have been applied in the design of desk lamps and are loved by users. At present, foldable desk lamps with simple designs in the market have gradually formed a popular trend.

In order to achieve the above object, the idea of the present invention is: the present invention realizes the folding and closing of the lamp cap and the upper bracket plate through the rotating shaft of the lamp cap and the upper bracket plate, when folding, the lamp cap device is protected; through the upper bracket plate and the lower bracket plate The rotating shaft realizes the rotation and scaling of the upper and lower support plates; the support and retraction of the base are realized through the rotating shaft of the lower support plate and the base. When in use, it can be unfolded into a desk lamp with a sufficient height; when it is stored, it can be folded into the size of a mobile phone, which not only protects the lamp head from collision damage, but also is small and exquisite and easy to carry.

According to above-mentioned inventive concept, the present invention adopts following technical scheme:

A foldable desk lamp, comprising a lamp base, an LED device mounted on the lamp base, a base, and two support plates, connecting the lamp base and the upper support plate, the upper support plate and the lower support plate, the lower support plate and the base with the rotating shaft , characterized by:

a. between the lamp holder and the upper support plate, between the upper support plate and the lower support plate, and between the lower support plate and the base are connected by rotating shafts;

b. LED devices are installed on the lamp cap, and the lamp cap can be rotated arbitrarily within a specified angle by the rotation of the rotary connection between the lamp cap and the upper support plate;

c. There is a clamping device between the upper support plate and the lower support plate to ensure that the upper support plate and the lower support plate cannot rotate without restriction, so as to prevent the wire from being turned bad when the desk lamp is routed;

d. The base is fitted with the lower support plate, that is, when folded, the base is embedded in the groove of the lower support plate, and the semi-circular shape of one end of the base helps to separate it from the lower support plate; the other end of the base is connected to the lower support plate The surface of the rotation joint is flat with the bottom surface of the base, and the base is perpendicular to the lower support plate when unfolded to prevent the desk lamp from tilting.

The structure of the rotating shaft between the lamp head and the upper support plate, and between the lower support plate and the base is the same: the rotating shaft is formed by screwing two connecting pieces with threads at both ends and a hole shaft with internal threads in the middle to form a complete rotating shaft , The hole shaft is wrapped with a damping ring to fix the angular position of the rotation; the rotating shaft is parallel to the support plate, and the support plate, the lamp head and the base realize folding.

The upper bracket plate is a shaft structure between the lower bracket plate: the shaft is a complete shaft that is screwed together by a connector with a thread and a connector with an internal thread, and there is a damping ring at each end of the shaft to Fix the angular position that has been turned, and play a role in stably maintaining the state of the mechanism. The rotating shaft is perpendicular to the two support plates to realize the relative plane rotation and scaling of the upper and lower support plates. The clamping device is a part of the upper support plate and the lower support plate. The edge also protrudes one piece, so that the upper and lower support plates interfere with each other and cannot turn over 360 ° when rotating, so as to ensure that the upper support plate and the lower support plate can not rotate without limit, and prevent the electric wire from being turned bad when the desk lamp is routed.

The length of the base of the above-mentioned foldable desk lamp is longer than half of the length of the lamp head, so as to ensure that it will not be toppled during use.

Compared with the prior art, the present invention has the following obvious outstanding substantive features and significant advantages:

1. The foldable desk lamp of the present invention has a simple shape and can be folded and shrunk into the size of a mobile phone, which not only protects the lamp cap of the desk lamp, but also is easy to carry.

2. The foldable desk lamp of the present invention has a simple and reliable structure, and is convenient for users to operate.
