Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention so that the technical solution of the present invention can be more easily understood and grasped, and should not be construed as limiting the present invention.

Example 1:

a charger shell is shown in figures 1 and 2 and comprises a box body 1, the adopted material is plastic, and the box body 1 is in a box cover shape. A plurality of rows of rectangular heat dissipation holes 2 are formed in one side face of the box body 1, a first wire groove 3 and a second wire groove 4 are arranged at the edge position below the heat dissipation holes 2 of the box body 1, the first wire groove 3 is flush with the surface of the box body 1, and the second wire groove 4 protrudes out of the surface of the box body 1. Charger shell adopts box-like structure to have reliable intensity, sets up louvre 2 in the side and can give off the temperature fast, increases the circulation of air, safe and reliable. Set up the wire casing in the heat dissipation position to can improve the radiating effect of wire casing, and have the different structure of first wire casing 3 and second wire casing 4, can be convenient for distinguish live wire or the zero line of installation. In this embodiment, two first wire slots 3 and two second wire slots 4 are also used, which can be used alternatively, and facilitate the arrangement of the wires.

In addition, referring to fig. 3 and 4, a panel window 5 is formed in the other side surface of the box main body 1, a connection column 6 is arranged on the box main body 1 at a position close to the panel window 5, a bolt 7 is arranged in the connection column 6 in a matching manner, and the connection column 6 is hollow and is in threaded fit with the bolt 7.

Further, a plurality of reinforcing ribs 8 are integrally formed on the inner sides of the connecting column 6 and the box main body 1. Thereby enhancing the internal structure without affecting the external appearance.

The key points are as follows: install on the inner wall of spliced pole 6 and be spiral helicine steel wire 9, the helical structure of steel wire 9 and the screw thread structure cooperation of bolt 7, 9 one end of steel wire are fixed on spliced pole 6, are provided with movable groove 10 on spliced pole 6, and the other end of steel wire 9 stretches out through movable groove 10, and steel wire 9 twines along the screw thread groove of bolt 7. The movable slot 10 faces the panel window 5. So that the hand can be inserted. The number of turns of the spiral of the steel wire 9 ranges from 1 to 4 turns.

Therefore, when the bolt 7 is used, when the bolt 7 is fed forward and screwed in, the steel wire 9 is expanded in a spiral state, the steel wire 9 has certain deformation capacity, when the bolt 7 is expanded, the binding force of the steel wire 9 on the bolt 7 is reduced, the spiral is easily screwed in, and if the bolt 7 needs to rotate reversely, the steel wire 9 is deformed and folded due to the reverse spiral force, so that the binding force of the steel wire 9 on the bolt 7 is increased, and the bolt 7 is not easy to screw out. If unscrewing is required, the free end of the wire 9, i.e. the end located in the free slot 10, needs to be manually operated so that the wire 9 is in a relaxed state so that the bolt 7 can be removed. The operation also reflects that in the operation process, a user needs to stretch into the panel window 5 by hands and poke the steel wire 9. The steel wire 9 is not longer, and 1-4 circles can control the binding force, so that the bolt 7 is more firmly fixed, and the bolt 7 is not easy to fall off.

Example 2:

based on embodiment 1, referring to fig. 4, the connection column 6 is further sleeved with a magnetic ring 11. Play the supplementary adsorption to bolt 7, prevent to drop in the bolt 7 location of being convenient for and the installation.

Of course, the above is only a typical example of the present invention, and besides, the present invention can also have other various specific embodiments, and all technical solutions adopting equivalent replacement or equivalent transformation are all within the scope of the present invention as claimed.
