Description
Technical Field
The invention relates to a safety component of low-voltage connecting equipment, in particular to a safety door formed by applying a lever principle.
Background
The existing wall socket and the mobile power supply patch board can be seen everywhere in daily life, but potential safety hazards exist generally, for example, when children insert a certain jack of the socket or the power supply patch board with conductive foreign matters held by curiosity, power contacts inside can be touched to cause electric shock danger, the safety accidents happen, and the use safety of the wall socket and the mobile power supply patch board is greatly influenced.
The invention patent of application No. 201010297882.4 provides a supporting sliding type safety door, the technical scheme is that a sliding block is arranged in an upper cover, two inclined planes inclined towards one direction are arranged on the outer side of the sliding block corresponding to two jacks, a convex supporting shaft is arranged on the inner side of the sliding block, when a metal foreign matter is inserted into one jack, the sliding block can rotate by taking the supporting shaft as a shaft, one end of the sliding block which is tilted can be blocked by a blocking rib, the sliding block can not move, and the metal foreign matter can be prevented from passing through; this technical scheme has solved current socket and patch board basically and has easily taken place the problem of electric shock danger, nevertheless still has following not enough: 1. when the plug is inserted, the plug abuts against the two inclined planes simultaneously to enable the sliding block to horizontally move towards one side, the plug is communicated with a power supply, in the process, the downward force of the plug is converted into the force in the horizontal direction through the two inclined planes, the force which is turned by 90 degrees is transmitted, the downward force is greatly consumed, and the required thrust for enabling the sliding block to horizontally slide can be achieved only by increasing the downward force, so that the plug can be inserted only by great force; 2. when the slider horizontal slip, the power that the plug is decurrent has increased the frictional force when the slider slides, makes slider sliding resistance increase, and then makes the gliding unsmooth of slider, influences the result of use.
Disclosure of Invention
Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a safety door using a lever principle, in which when a conductive foreign object is inserted into an insertion hole on one side of the safety door, a large force is required to continue the insertion, and a child does not have the large force, so that the risk of electric shock can be prevented; when the plug is inserted, the safety door can be influenced by the labor-saving lever principle, the plug can be easily and smoothly inserted, and the use satisfaction of a user is improved.
The safety door formed by utilizing the lever principle is arranged in an upper cover of a socket or a patch board, the upper cover is provided with at least one pair of insertion holes, and the outer sides of lower ports of the insertion holes extend downwards to form square stopping parts;
the safety door formed by the lever principle is provided with a left door plate and a right door plate, the two door plates are horizontally arranged on a support relatively through a support shaft, the left door plate and the right door plate are door plates which can be respectively opened in a downward rotating mode along the left side and the right side of the support, the support is provided with a lever through a sliding groove frame arranged on opposite side walls at two ends, the left door plate is close to the rear end and extends towards one side of the right door plate to form a C-shaped notch I, the C-shaped notch I is clamped on the outer peripheral side of the lever, the width of a notch of the C-shaped clamping groove I is larger than or equal to the diameter of the lever to allow the lever to be freely moved out, the right door plate is close to the front end and extends towards one side of the left door plate to form a C-shaped notch II, the C-shaped notch II.
Furthermore, the lever is a cylinder, two ends of the lever are provided with convex rectangular sliding blocks, and the rectangular sliding blocks are inserted into the sliding grooves and are abutted against the wall surfaces of the sliding grooves.
Furthermore, after the two ends of the lever are provided with the protruding rectangular sliding blocks which are inserted into the sliding grooves, the lever end surfaces on the two sides of each rectangular sliding block are abutted to the side walls of the support frame;
furthermore, the top ends of the rectangular sliding blocks protruding from the two ends of the lever are in a non-contact state with the bottom surface of the sliding groove, and the end surfaces of the two ends of the lever are in a non-contact state with the inner side wall surface of the bracket.
Advantageous effects
1. In the normal use process of the door handle, the C-shaped clamping groove I at the rear end of the left door plate and the C-shaped clamping groove II at the front end of the right door plate simultaneously apply force from the front end and the rear end of the lever to horizontally support the lever upwards, at the moment, the left door plate takes the supporting shaft as a fulcrum and prizes the lever through the C-shaped clamping groove I, the right door plate takes the supporting shaft as the fulcrum and prizes the lever through the C-shaped clamping groove II, and the left door plate and the right door plate are both in a labor-saving lever state, so that the left door plate and the right door plate can be easily rotated and opened.
2. In this technical scheme, under the abnormal use condition, when left door plant is pressed alone, C font draw-in groove prizes lever rear end earlier on, makes the lever be the high front-low tilt state in back, and the lever under this tilt state can lead to the rectangle slider card at lever both ends to support at the wall surface of sliding chute, makes the unable rebound of lever, and then the unable lever that removes can support C font draw-in groove one and make the unable removal of left door plant.
3. In this technical scheme, under the abnormal use condition, like right-hand door board independent pressurized, C font draw-in groove two is upwards sled and is moved the lever front end, makes the lever be the tilt state of high back low before, and the lever under this tilt state also can lead to the rectangle slider card at lever both ends to support at the wall of the slide groove, and then makes the unable rebound of lever, and then makes the unable removal of right-hand door board.
4. In the technical scheme, if the left door plate is independently pressed, the C-shaped clamping groove prizes the rear end of the lever upwards to enable the lever to be in an inclined state with a high rear part and a low front part, the end faces of two ends of the lever in the inclined state are clamped on the wall surface of the inner side wall of the bracket, the lever cannot move upwards, and the lever which cannot move abuts against the C-shaped clamping groove to enable the left door plate to not move; on the contrary, if the right door plate is independently pressed, the front end of the lever is pried upwards by the C-shaped groove opening, so that the lever is in an inclined state with a high front part and a low back part, the end faces of the two ends of the lever in the inclined state are clamped on the wall surface of the inner side wall of the support, the lever cannot move upwards, and the right door plate cannot move.
5. In the technical scheme, if the left door plate is independently pressed, the C-shaped clamping groove prizes the rear end of the lever upwards, then the lever is used for prying the C-shaped notch II arranged at the front end of the lever, so that the left door plate can move after the right door plate moves, the state is equivalent to holding one end of a long rod by hand, and then the other end of the long rod is used for picking up objects, so that great labor is consumed, and the left door plate cannot be easily opened; on the contrary, if the right door panel 5 is pressed alone, the same principle makes the right door panel 5 not be opened easily.
