Abstract

The utility model discloses a hand-generating desk lamp, solving the defect that the structure of the existing desk damp which does not have strong practicability is not compact, etc. Primarily, a crank handle (4) of the existing hand-generating desk lamp is designed into a discoid crank handle whose edge is provided with crank handle particles; a circular plane (11) matched with the crank handle (4) is arranged at the outer side of a top cover of a base (1) of the desk lamp; the center of the crank handle (4) is connected with a rotating shaft (31) of a generator (3) to be locked; the hand generator (3) simultaneously charges a set of high-performance rechargeable batteries (8) via a charger (7); at least two paralleled LED lamps (61) are arranged in a lamp cap (6) of the desk lamp. With the utility model, the structure of the desk lamp is compactor, prolonging the lighting time, and enhancing the brightness of the desk lamp effectively.

Description

But the desk lamp of hand power

Technical field

The utility model relates to a kind of daily living article, relates in particular to a kind of desk lamp that can hand power.

Background technology

Existing desk lamp generally comprises base, support and lamp holder, and the support that electric wire passes hollow joins lamp holder and external power, usually, also is provided with the switching that switch is controlled desk lamp on base.

In order to reach power saving, environmental protection requirement, hand microgenerator is existing the application in a lot of emergent products, because the electric weight of hand power is limited, when emergency lighting, often exist lighting hours shorter, perhaps defective such as light luminance deficiency, in addition, existing hand microgenerator generally uses rocking handle to drive the interior generator for electricity generation of housing, this structure applications is on the desk lamp of family expenses; parts such as rocking handle, housing only are simple connections; it is not compact to mutually combine, and makes that the appearance design of desk lamp is pind down, and is difficult for receiving the effect of harmony.

Summary of the invention

Technical problem to be solved in the utility model is intended to provide a kind of lighting hours long, sufficient brightness, but the desk lamp of the hand power of compact conformation.

According to the utility model, but a kind of desk lamp of hand power, comprise base upper cover, the base lower cover, place the generator between described base upper cover and the base lower cover, place the rocking handle in the described base upper cover outside, and support, lamp holder, charger and rechargeable battery, the output of described generator and the input of described charger join, the output of described charger and described rechargeable battery join, the electric wire of the support of described rechargeable battery and described lamp holder through passing hollow with join as the power supply of lamp holder, described rocking handle is the discoid rocking handle that the edge has the rocking handle grain, and the arranged outside of described base upper cover has the circular flat that matches with described rocking handle, and the center of described rocking handle is connected with the rotating shaft of described generator and locks, described rechargeable battery is one group of high-performance rechargeable battery, is provided with the LED lamp of at least two parallel connections in the described lamp holder.

After adopting the utility model, because common shaft-like rocking handle is designed to discoid rocking handle, and the base upper cover of desk lamp is provided with the circular flat that matches with discoid rocking handle, therefore the combination of rocking handle and base upper cover is more compact, harmonious, utilize one group of high-performance rechargeable battery to replace single battery can prolong lighting hours simultaneously, be provided with the brightness that the LED lamp of at least two parallel connections also can improve desk lamp effectively with the capacitance that strengthens rechargeable battery.

The purpose of this utility model, feature and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.

Description of drawings

But Fig. 1 is the decomposition texture schematic diagram of the desk lamp of the utility model hand power;

But Fig. 2 is the circuit theory diagrams of the desk lamp of the utility model hand power;

But Fig. 3 is the appearance assumption diagram of the desk lamp of the utility model hand power.

Concrete embodiment

With reference to Fig. 1 and Fig. 2, but the desk lamp of a kind of hand power of the present utility model, comprise base upper cover 1, base lower cover 2, place the generator 3 between described base upper cover 1 and the base lower cover 2, place the rocking handle 4 in described base upper cover 1 outside, and support 5, lamp holder 6, charger 7 and rechargeable battery 8, the input of the output of described generator 3 and described charger 7 joins, the output of described charger 7 and described rechargeable battery 8 join, the electric wire of the support 5 of described rechargeable battery 8 and described lamp holder 6 through passing hollow with join as the power supply of lamp holder 6, described rocking handle 4 has the discoid rocking handle of rocking handle grain 41 for the edge, and the arranged outside of described base upper cover 1 has the circular flat 11 that matches with described rocking handle 4, and the center of described rocking handle 4 is connected with the rotating shaft 31 of described generator 3 and locks, described rechargeable battery 8 is one group of high-performance rechargeable battery, is provided with the LED lamp 61 of four parallel connections in the described lamp holder 6.

In Fig. 1, the structure of the generator 3 of hand-rail type can adopt existing universal architecture, as drive one group of accelerating gear generating by rotating shaft 31, gives unnecessary details no longer in detail at this.In the utility model because common shaft-like rocking handle is designed to discoid rocking handle, and the base upper cover of desk lamp is provided with the circular flat that matches with discoid rocking handle, therefore the combination of rocking handle and base upper cover is more compact, harmonious, as shown in Figure 3, discoid rocking handle rotates not only stable at the drive lower edge of rocking handle grain 41 circular flat, proper, and make function of the present utility model and outward appearance be unified harmoniously.

In order to overcome in the prior art, the desk lamp lighting hours is shorter, perhaps defective such as light luminance deficiency, the rechargeable battery 8 that the utility model uses is one group of high-performance rechargeable battery, the generator 3 of hand-rail type charges to this group high-performance rechargeable battery simultaneously through charger 7, to guarantee charging capacity, in addition owing to use a plurality of than common bulb power saving tens of times LED lamp 61 approximately, and adopt mode in parallel to connect, use three (or four) LED lamp in parallel as shown in Figure 2, when desk lamp is opened, can increase brightness of illumination exponentially like this.After above improvement, practicality of the present utility model is stronger, and structure is also also uncomplicated, thereby is more convenient for promoting.
