Description
Technical field
The utility model belongs to electric blanket technical field, particularly relates to a kind of cylindrical plugging member for electric blanket.
Background technology
Electric blanket, has another name called electrical blanket, is a kind of contact electric heating appliance.The heating wire that special insulation property are reached standard by it penetrates in woollen blanket in dish serpentine, during energising and the evolution of heat.Be mainly used in warming oneself when people sleep.
And the main components be connected with power supply by electric heating element is plugging member, general plugging member comprises plug-in unit and pulls out part, plug is grafting with pulling out part, and the metalwork of plug is connected with the sheet metal pulled out in part makes power supply and electric heating element UNICOM, the thus electric heating element evolution of heat.Plug side is often power cord connector, pull out part side to be connected with electric blanket body, but adopt the plugging member of above-mentioned prior art, owing to only considered the convenient function of use, do not consider due to problems such as the plugging member loose contacts that repeatedly swapping process causes, cause loose contact that electric blanket is not generated heat after one side access times are many, the plug current-carrying part arcing of plugging member may be caused on the other hand, thus cause fire.
Summary of the invention
The purpose of this utility model is just to provide a kind of cylindrical plugging member for electric blanket, and easy to use, long service life, potential safety hazard is low.
To achieve these goals, technical solutions of the utility model are as follows:
For a cylindrical plugging member for electric blanket, comprise plug and pull out part, also comprising fixed cap, described plug and pull out part grafting, the described part lateral wall that pulls out is provided with external screw thread, and described fixed cap inwall is provided with the internal thread coordinated with external screw thread, described plug and pull out part and be cylindrical structural.
Further, described fixed cap comprises cylindrical body, circular cylindrical cavity is provided with in described cylindrical body, described cylindrical body one end is inwardly shunk and is formed inclination truncated cone-shaped, be provided with truncated cone-shaped cavity in described inclination truncated cone-shaped, described inclination truncated cone-shaped lower end is inwardly shunk and is formed with the first spacing ring.
Further, described plug one end is the power line for connecting power supply, and the other end is the head of built-in metal electric-conductor, and described head is provided with the second spacing ring that cross section is right-angled trapezium.
Further, the opening direction of described fixed cap is arranged towards pulling out part, and the second spacing ring clamping of the first spacing ring of fixed cap and plug.
Further, described fixed cap lateral wall is provided with some uniform antifriction lines.
The cylindrical plugging member for electric blanket that the utility model proposes, plug and pull out between part and adopt fixed cap to connect, plug is cylindrical structural with pulling out part, first plug and pull out part grafting, again by fixed cap with pull out part and be threaded, thoroughly solve the problem of plugging member in use loose contact, make with this type of plugging member electric blanket, pad use more safe and reliable, long service life.
