Firstly, the extrusion block 42 is pushed by the control part 43, the motion of the extrusion block 42 is horizontal movement, the force is decomposed under the angles of the extrusion inclined plane 421 and the sliding inclined plane 412, the sliding block 41 changes into the movement in the front-back direction, and the specific movement rule is as follows: the control part 43 pushes the extrusion block 42, and the extrusion block 42 extrudes into the shell 1, so that the sliding block 41 moves backwards; if the control portion 43 no longer pushes the pressing block 42, the pressing block 42 springs outward under the elastic force of the limit spring 413, the pressing block 42 no longer presses the sliding block 41, and the sliding block 41 moves forward under the external force.
In order to allow the sliding block 41 to have an external force to move forward, a return spring 414 is provided between the sliding block 41 and the housing 1. That is, when the control portion 43 no longer pushes the pressing block 42 to press the slide block 41, the slide block 41 is returned by the elastic force of the return spring 414.
Of course, the number of the return springs 414 is at least one. The return springs 414 work together to make the return process of the slide block 41 smoother and more stable in use.
Example two: as shown in fig. 1 to 4, which are only one embodiment of the present invention, the above is only a rotation scheme of the present invention, but in order to make the plug rotate more conveniently, the opening and closing angle of the plug is more reasonable, and the user uses more conveniently, the following design is also needed:
first, it is necessary to design: the control part 43 comprises a control rod 431 and a limiting ring 432, wherein at least one part of the control rod 431 is arranged in the extrusion block 42, and the limiting ring 432 is connected with the limiting spring 413.
Control lever 431 and extrusion piece 42 are structure as an organic whole, and when control extrusion piece 42 extrudeed then, the device is more stable, and the atress is more convenient, and spacing ring 432 is then also connected with spacing spring 413 better, and spacing spring 413 that is to control part 43 and extrusion piece 42's limiting displacement more inseparable.
Actually, the number of the control portions 43 is 2. Correspondingly, the number of the extrusion blocks 42 is also 2, and the two control parts 43 are respectively connected with the two ends of the limiting spring 413, so that the user can press the control parts more conveniently.
Then, the first groove 22 and the second groove 32 are V-shaped grooves. Just receive the third and fourth projecting portions 46, 47 of the sliding block 41.
The two grooves are designed to satisfy the most rationalization of the pushing distance and the pushing angle of the two conductive devices when the sliding block 41 moves back and forth, and the included angle between the two concave surfaces of the first groove 22 and the included angle between the two concave surfaces of the second groove 32 are both 70 ° to 150 °. That is to say, the concave included angle of the groove is related to the opening angle of the conductive device, and the smaller the concave included angle of the groove is, the smaller the extrusion wheelbase of the groove when the sliding block 41 slides is, the same sliding distance is obtained, and the larger the rotation angle of the conductive device is, the larger the opening angle of the plug is; on the contrary, the larger the included angle of the concave surface of the groove is, the smaller the opening angle of the plug is.
Finally, it should be noted that the housing 1 is provided with a contact surface 13 connected to the first conductive device 2 and the second conductive device 3, the contact surface 13 is provided with a first through hole 11 and a second through hole 12, at least a portion of the first conductive device 2 is located in the first through hole 11, and at least a portion of the second conductive device 3 is located in the second through hole 12.
Moreover, for better use of the plug, the angle between the first through hole 11 and the contact surface 13 ranges from 60 ° to 89 °, and the angle between the second through hole 12 and the contact surface 13 ranges from 60 ° to 89 °.
That is to say, the first through hole 11 and the second through hole 12 are oblique through holes, and the oblique direction is the same as the opening direction of the plug, so when the plug is opened, the stress state of the plug is more appropriate, and meanwhile, an effective dustproof effect can be performed.
In a third embodiment, as shown in fig. 5, in order to perfect a technical solution of the rotary plug of the present invention, a plug rotating method of a rotary plug is provided, the method including the following steps:
s1: when the plug is plugged, the pressing control part pushes the extrusion block to extrude the sliding block, and the sliding block moves backwards;
s2: the third protruding part and the fourth protruding part of the sliding block respectively extrude the first groove of the first conducting device and the second groove of the second conducting device, so that the front ends of the first conducting device and the second conducting device are rotationally closed to be parallel to each other;
s3: after the plugging and unplugging are finished, the control part is released, and the sliding block moves forwards under the action of the return spring;
s4: the first protruding part and the second protruding part of the sliding block respectively extrude a first wedge block of the first conducting device and a second wedge block of the second conducting device, so that the front ends of the first conducting device and the second conducting device rotate to be opened to keep a preset opening angle.
The first two steps are completed under the action of force of a user, and the opening angle of the plug is controlled to be closed to be parallel; the second two steps are that after the user stops applying force, the self reset spring of the device is completed, and the opening angle of the plug is opened to form a preset opening angle.
In this method, when step S1 is executed, the pressing slope of the pressing block and the sliding slope of the sliding block are on the same plane.
The extrusion piece is more stable to the extrusion of sliding block so, can not appear the dead phenomenon that leads to uncontrollable slip of position card.
In this method, the first and second conductive means are set to a predetermined opening angle before step S4 is performed. The predetermined opening angle is generally set by designing the concave angle of the first and second grooves. Besides the concave included angle, the inclined angle of the sliding slope of the sliding block can be designed. Meanwhile, the inclined angle of the extrusion inclined surface of the extrusion block is the same as that of the sliding inclined surface.
The design of the first groove and the second groove is optimized for meeting the pushing distance and the pushing angle of the two conducting devices when the sliding block moves back and forth, and the included angle range between the two concave surfaces of the first groove and the included angle range between the two concave surfaces of the second groove are both 70 degrees to 150 degrees. That is to say, the concave included angle of the groove is related to the opening angle of the conductive device, the smaller the concave included angle of the groove is, the smaller the extrusion wheelbase of the groove is when the sliding block slides, the same sliding distance is obtained, the larger the rotation angle of the conductive device is, the larger the opening angle of the plug is; on the contrary, the larger the included angle of the concave surface of the groove is, the smaller the opening angle of the plug is.
To summarize, the predetermined opening angle is set as follows:
the smaller the included angle design of the concave surfaces of the first groove and the second groove is, or the larger the inclined angle of the sliding slope of the sliding block is, the larger the preset opening angle of the first conductive device and the second conductive device is;
the larger the included angle between the concave surfaces of the first groove and the second groove is designed, or the smaller the inclination angle of the sliding inclined surface of the sliding block is, the smaller the preset opening angle between the first conducting device and the second conducting device is.
The rotary plug is simple in structure, convenient to use, rotatable, easy to pull and insert, small in damage to the socket and capable of greatly reducing production cost.
The present invention is not limited to the above-described specific embodiments, and various modifications and variations are possible. Any modifications, equivalents, improvements and the like made to the above embodiments in accordance with the technical spirit of the present invention should be included in the scope of the present invention.
