Abstract
The utility model refers to an outage and electric shock prevention wiring board, comprising a power supply fixed column, a rotating gland and a torque spring. The rotating gland is arranged on the wiring board and is located above the power supply fixed column; the rotating gland is provided with a through hole corresponding with a power supply jack; when not in use, the through hole and the power supply jack are staggered owing to the torque spring; and in use, the through hole is rotated right above the power supply jack, one end of the torque spring is in connection with the rotating gland and the other end is in fixed connection with the power supply fixed column. According to the utility model, the problem is solved that all wiring boards age owing to increase of service time and number of use, which leads to looseness of the power supply jack; the looseness of the power supply jack causes bad contact between an electric appliance plug and a wiring board and leads to outage; the service efficiency of the wiring board is raised, the service life of the wiring board is prolonged and safety performance of the wiring board is improved.
Description
Technical field
The utility model relates to a kind of power consumption equipment, refers to a kind of wiring board of anti-power failure protection against electric shock especially.
Background technology
There is following problem in the wiring board of prior art: 1, most of wiring boards are owing to increasing of service time and access times wears out, and make jack is loosening and cause electrical appliance plug and wiring board loose contact and the problem of cutting off the power supply; 2, jack opens wide caused safety problem; 3, the useful life of plug wire machine too short problem.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of protection against electric shock anti-power failure wiring board.
The utility model is a kind of anti-power failure protection against electric shock wiring board, comprise the power supply fixed leg, the rotation gland, torque spring, described rotation gland are arranged on the wiring board and are positioned at the top of power supply fixed leg, the through hole corresponding with supply hub is set on the described rotation gland, when not using, being staggeredly located out of described through hole and supply hub changeed through hole directly over supply hub during use, one end of described torque spring connects rotation gland, the fixedly connected power supply fixed leg of the other end.
Preferably, the elastic force adjustment hole that several adjust spring force is set on the described rotation gland, described torque spring is fixedly connected in the elastic force adjustment hole.
Preferably, described power supply fixed leg top arranges several elastic force adjustment holes of adjusting spring force, and described torque spring is fixedly connected in the elastic force adjustment hole.
Preferably, the plate gland is set also, described plate gland is arranged on and will rotates gland on the rotation gland edge and be squeezed on the wiring board.
Useful technique effect of the present utility model is: the utility model wiring board has solved all wiring boards owing to increasing of service time and access times wears out, the problem that makes supply hub is loosening and cause electrical appliance plug and wiring board loose contact and cut off the power supply, prolong service efficiency and the life-span of wiring board, improved the security performance of wiring board.
When not using, being staggeredly located out of the through hole of described rotation gland and supply hub covers supply hub by the rotation gland, can prevent effectively that child is owing to getting an electric shock in the charged position that touches wiring board.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
The utility model is a kind of anti-power failure protection against electric shock wiring board, comprise power supply fixed leg 1, rotation gland 2, torque spring, described rotation gland are arranged on the wiring board and are positioned at the top of power supply fixed leg, and the through hole 3 corresponding with supply hub is set on the described rotation gland, when not using, being staggeredly located out of described through hole and supply hub 4 covers supply hub by the rotation gland, can prevent effectively that child is owing to getting an electric shock in the charged position that touches wiring board.
During use, rotate described rotation gland, through hole is changeed directly over supply hub, attaching plug can be inserted in the wiring board.One end of described torque spring connects rotation gland, the fixedly connected power supply fixed leg of the other end.Because the elastic force effect of torque spring is fastenedly connected attaching plug and supply hub.
The utility model is that the torque that utilizes torque spring to produce makes attaching plug contact with supply hub, so as long as spring (existing mature technology) does not damage, the phenomenon of loose contact just can not appear in wiring board and attaching plug.
Preferably, the elastic force adjustment hole 5 that several adjust spring force is set on the described rotation gland, described torque spring is fixedly connected in the elastic force adjustment hole.Described power supply fixed leg top arranges several elastic force adjustment holes of adjusting spring force, and described torque spring is fixedly connected in the elastic force adjustment hole.Like this, by the elastic force adjustment hole is set, can regulate the elastic force of torque spring.After using a period of time, the phenomenon of relaxing one's efforts appears in torque spring, and elastic force descends, and adjusts the position of elastic force adjustment hole, can change the elastic force of torque spring, prolongs the useful life of wiring board.
Preferably, plate gland 6 is set also, described plate gland is arranged on and will rotates gland on the rotation gland edge and be squeezed on the wiring board, pushes down the rotation gland, and wraps torque spring, and torque spring needn't be leaked outside cruelly.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection range of the present utility model.
Claims (4)
1. anti-power failure protection against electric shock wiring board, it is characterized in that, comprise the power supply fixed leg, the rotation gland, torque spring, described rotation gland is arranged on the wiring board and is positioned at the top of power supply fixed leg, the through hole corresponding with supply hub is set on the described rotation gland, when not using, stagger mutually because of torque spring elastic force in the position of described through hole and supply hub, during use through hole is changeed directly over supply hub, an end of described torque spring connects rotation gland, the fixedly connected power supply fixed leg of the other end.
