Description

A charger with a pull-out device

technical field

The utility model relates to a charger for digital equipment, which belongs to the technical field of chargers, in particular to a charger provided with a pulling device.

Background technique

Today, with the rapid development of science and technology, there are more and more electronic devices for information transmission and entertainment, such as mobile phones, MP3, MP4, PDA, cameras and children's audio-visual education and other digital products, all of which need to be equipped with and use chargers. The charger needs to be plugged or unplugged frequently to connect or disconnect from the power outlet. For fixed-installed power sockets, the charger can be pulled out relatively easily; When pulling out the charger, you need to use both hands, press the mop board with one hand, and pull the charger out of the socket with the other hand. For the mop board with multiple plugs, it is not only inconvenient but also not safe; when children use audio-visual education, etc. For digital products, when unplugging the charger, if the operation is improper, electric shock accidents will occur.

Contents of the invention

The technical problem to be solved by the utility model is to overcome the problem of inconvenient use of the existing charger, and provide a charger with a simple structure, easy to use, which can be easily pulled out from the socket and equipped with a pull-out device.

In order to solve the above-mentioned technical problems, the technical solution of the utility model is realized as follows: a charger provided with a pull-out device, including a PCB board, a pin seat, a housing on the upper part of the pin seat, and an AC set on the pin seat Pins, the PCB board is placed in the housing and electrically connected to the AC pins. It is characterized in that: the pin base is provided with a lifting device, and the lifting device is movably installed on the pin base;

A protruding hinge part is provided on one side of the socket, and a pin hole is provided on the hinge part, and the lifting device is movably installed on the hinge part.

The lifting device is composed of a curved lever-shaped two-fork crowbar and a pin shaft. The upper end of the two-fork crowbar is a force plate, and the lower part is two crowbars. The curved connection between the force plate and the two crowbars is provided with Axle hole; the pin shaft passes through the shaft hole of the two-fork pry bar, and the pin hole of the pin seat connects the two-prong pry bar with the pin seat.

The upper end of the hinge part of the socket and the housing are provided with a groove for accommodating the force plate. The force plate is a groove-shaped structure, and its inner wall corresponds to the groove on the housing.

Both sides of the bottom of the pin seat are provided with grooves for accommodating double-prong crowbars.

The two sides of the groove on the outer wall at the upper end of the pin seat hinge are provided with protrusions for positioning the force plate.

The beneficial effect of the utility model is that because the charger is provided with a pull-out device, the charger is conveniently pulled out by using the principle of leverage.

When pulling out the charger, just press the force plate of the pulling device inward, and the two crowbars will pry the AC pin out from the socket, and the charger will pop out; therefore, it only needs to be pulled out with one hand, which is simple, labor-saving, safe and practical.

Detailed ways

Below in conjunction with accompanying drawing, the embodiment of the present utility model is described in detail:

Referring to Fig. 1 and Fig. 2 is the charger of the present utility model, the charger of the present utility model is provided with pull-out device by PCB board, pin seat 1, shell 2 on the top of pin seat 1 and the AC pin that is arranged on the pin seat 3 composition. The PCB board is placed in the housing 2 and is electrically connected to the AC pin 3 . A lifting device 4 is provided on the pin base 1 , and the lifting device 4 is movably installed on the pin base 1 .

One side of the socket 1 is provided with a protruding hinged part 11 , and a pin hole 12 is provided on the hinged part 11 . Referring to FIG. 4 , the lifting device 4 is movably mounted on the hinged part 11 .

Referring to Figures 6 and 7, the lifting device 4 is composed of a curved lever-shaped double-fork crowbar 41 and a pin shaft 42, the upper end of the double-fork crowbar 41 is a force plate 411, and the lower part is two crowbars 412 , the angle connection between force plate 411 and two pry bars 412 is provided with shaft hole 413; The seats 1 are connected together, and the two crowbars 412 are movably placed on both sides of the hinge part 11 of the pin seat 1 . When pulling out the charger, when the finger presses the force plate 411 on the upper end of the lifting device 4 inwardly, the two crowbars 412 at the lower end rotate accordingly, and the free ends of the two crowbars begin to squeeze the socket downward, so that the AC pin 3 Separated from the elastic connecting piece in the socket, when separated to a certain distance, the AC pin 3 will pop out from the connecting piece and completely disengage, thus completing the pulling out of the charger.

Referring to Fig. 5 , grooves 13 for accommodating two crowbars are provided on both sides of the bottom of the socket 1. When the two AC pins 3 of the charger are inserted into the socket, the two crowbars 412 of the double-fork crowbar 41 just press into the two crowbars at the bottom. The groove 13 on the side makes the charger sit on the socket smoothly.

The upper end of the hinge part 11 of the socket 1 and the housing 2 are provided with a groove 21 for accommodating a force plate 411 . The force plate 411 is a groove-shaped structure, and its inner wall corresponds to the groove 21 on the housing.

On the upper end of the hinge part 11 of the socket 1 and on both sides of the groove 21 on the housing 2, there are protrusions 22 for the positioning of the force plate 411. When the charger is pulled out, the force plate 411 is thus embedded in the fitting on the housing 2. In the groove 21, due to the positioning of the protrusion 22, the force plate 411 is fixed in the groove 21, and when inserted into the socket, it can be easily ejected. In addition: because the force plate 411 is embedded in the groove 21, the force plate 411 The outer edge of the board 411 is consistent with the casing 2, which increases the overall appearance of the charger.

The utility model has the advantages of reasonable design, convenient use, creativity and practicability. Because the charger is equipped with a pull-out device, when people pull out the charger, they only need to press the force plate of the pull-out device inward, and use the principle of leverage, and the two crowbars will Pry out the AC pin from the socket; pulling out the charger saves effort and prevents possible electric shock accidents, which is of good use value.

The above description is only an example of the present invention, and does not limit the implementation scope of the present utility model. All equivalent changes and modifications made according to the structure, features and principles of the scope of the present application should be included in the protection scope of the utility model application.
