Detailed Description

The terms used in the present invention have the meanings commonly understood by those of ordinary skill in the art, unless otherwise specified.

The present invention will be described in further detail with reference to the following data in conjunction with specific embodiments. The following examples are intended to illustrate the invention, but not to limit the scope of the invention in any way.

As shown in fig. 1 and 2, a rotary tail plug for an electric heating mat comprises a tail plug part 2 for connecting with a power line, and further comprises a fixed seat 1 fixed on the electric heating mat; the tail plug part 2 is rotatably connected with the fixed seat 1. Specifically, 2 one end of tail portion of inserting is connected with the power cord, and the other end is connected with the heat-generating body in the electric heating pad, and when the intercommunication power, the heat-generating body heating. The heating body is a material that can be used for electric heating, such as a heating wire or a carbon fiber heating wire. Because the devices connected with the power supply on the existing heating pad are all fixed, for example, an electric blanket, when the electric blanket is used, if the position of a socket installed in a home is inconsistent with the direction of the extending power line of the power supply device fixed on the electric blanket, the power line can be inserted into the socket only by bending, the circuit is easy to wear after long-time use, and the electric blanket is inconvenient to use and also has an influence on the appearance. And the utility model discloses a this kind of rotatory tail is inserted, can be according to actual demand, the rotation angle that the adjustment tail was inserted no matter socket installation is in which direction, can both be very convenient insert the tail with the power cord and insert in.

As shown in fig. 3, the tail plug 2 includes a housing 2-1, a connection terminal 2-2 disposed on the housing 2-1, and a buckle 2-3 disposed on the housing 2-1 and close to the side of the fixing seat 1; the fixed seat 1 is provided with an annular track 1-1 for the rotation of the buckle 2-3. The connecting terminal 2-2 can be fixed on the shell 2-1 in a bonding, clamping or splicing mode, when the electric heating mat is used, one end of the connecting terminal 2-2 is connected with a power line, and the other end of the connecting terminal is connected with a heating body of the electric heating mat. The structure realizes the rotation of the tail plug part 2 by the way that the buckle 2-3 rotates around the annular track 1-1. In addition, fig. 3 shows a preferred structure diagram of the shell 2-1 configured as a double layer, but in the present invention, the shell 2-1 may also be configured as a single layer, and other structure configurations are shown in fig. 3, and a schematic diagram of configuring a single layer of shell is not given here.

The mode that the buckle 2-3 rotates around the annular track 1-1 is various, the utility model provides an implementable scheme, as shown in fig. 3 and fig. 4, a circular through hole 1-2 is arranged on the fixed seat 1, and the circular wall of the circular through hole 1-2 is the track 1-1; the buckle 2-3 is L-shaped and comprises a connecting arm 2-31 and a clamping arm 2-32; the clamping arms 2-32 and the shell 2-1 are respectively positioned on two sides of the wall surface where the circular through hole 1-2 is positioned. The shell 2-1 and the clamping arms 2-32 are respectively fixed at two ends of the connecting arm 2-31, when the connecting device is installed, the buckle 2-3 is clamped into the circular through hole 1-2, and the clamping arms 2-32 are clamped at the opposite side of the shell 2-1 after penetrating through the circular through hole 1-2, so that the buckle 2-3 rotates around the track 1-1.

If the tail plug part rotates excessively, the problem of winding the power line can be caused, and therefore, as shown in fig. 5, a limiting block 1-21 for limiting the rotation of the buckle 2-3 is further arranged on the circular through hole 1-2. The position of the connecting arm 2-31 can be limited by the limiting block 1-21, and the position of the clamping arm 2-32 can also be limited, which is not specifically limited, as long as the buckle 2-3 cannot rotate continuously when moving to the limiting block 1-21. The limiting blocks 1-21 shown in fig. 5 can limit the movement of the clamping arms 2-32, and the limiting blocks 1-21 can also be arranged on the inner wall of the shell 2-1 at the circular through hole 1-2 for limiting the movement of the connecting arms 2-31.
