New description: • [New technical field] This creation is about a kind of fast bidirectional switch, especially the contact plate can be made on the two symmetrical tilting ridges on the bottom surface of the base groove. The bottom edge of the slab is ugly. _The inside of the hole in the ejaculation is used to reach the battle and the pure or the close can be borrowed (four) the spring in the ship's eccentricity, speeding up and amplifying the instantaneous shifting effect' as a diagonal press The positioning point switching action, so that the contact plate can quickly contact the connecting link of the two-way power supply and the refusal to turn the _ force to restore the position at the position, the piston can be quickly turned on and off the power supply, and Prevent the switch from switching between the switching currents due to the current frequency » 2 ', which produces a momentary high-definition moment, and the metal oxidation caused by high heat, which greatly reduces the bidirectional switch life and thus causes the fire of the power supply. . [Prior Art] For the fast two-way switch, please refer to the figures - to the third figure. As can be seen from the figure, in the conventional fast bidirectional switch, a switch button is provided in the housing, and a spring is arranged under the button. In the above, the spring is reversely elastically pushed by the change of the button to perform the switching action, as shown in the first figure, # is a non-conducting state, and is pressed by the B strut when the button A-end is pressed downward. The missile cyan c is formed to wrap around the plate, so that the bottom strut D is reversely pressed against the contact plate E, so that the whole body is in a non-conducting state, and then the second figure to the first figure is clamped to a conductive process, and the button is switched. When the manual switch is performed, the button A and the lower contact plate E are in an asymptotic tilt state, and since the spring C is reacted by the strut B and D, when the contact plate E is shortened from the power supply end F, it is easy to generate. The discharge action is slow as close to it, not once in place, so it is an unstable resistance conductive effect, easy to generate high heat, and easy to have spark splashing, full of female sex, the contact of one button and the other end of the circuit, Due to its connection When the touch is made, the button is used to switch the card position directly to conduct electricity, but because the button is manually pressed by the human body, and the spring is slow to operate, 5 M293518 •..., the person is in place, unless the special action is taken, otherwise the two buttons are connected after the touch The contact of the power supply is ten seconds, but the current frequency is 1/60 second for switching. Therefore, when the button is touched by the manual, the copper is turned on, and perhaps the electric ship is equipped with the ship: if it is, when Wei is in the thief , all will produce incomplete guide state, because the system is separated or combined with the distance to generate _ such as lightning in the air - electricity phenomenon, it will inevitably produce quite high heat, if this, it is easy to cause deformation of related components, the same, stomach In the thermal phenomenon of discharge, thermal oxidation phenomenon will also occur, which accelerates the oxidative deterioration of the metal on the contact surface, and the use of the ring switch, and the hysteresis effect caused by the manual button is not good. If the formation of the conductive state is unstable, a surge effect of the voltage will also occur. If this, the production of σα ' using the switch will also have the adverse effect of voltage instability, which will greatly reduce the effect and life of the health product. Life. It can be seen that there are still many shortcomings and shortcomings in the above-mentioned conventional fast switch, which is not a good designer, and needs to be improved. The creators of this case have all the shortcomings and shortcomings derived from the above-mentioned fast switches. They have improved and innovated, and after years of painstaking research, they finally succeeded in developing and developing this fast bidirectional switch.

The elastic member in the telescopic rod will pop up quickly', that is, the effect of increasing the contact with the elastic structure, and the contact surface of the switch will be started quickly when pressed to the point of satisfaction, and the lag time of the contact is reduced by using the machine. The contact plate is quickly turned on, avoiding the spark discharge phenomenon, greatly increasing the service life, and the product is stable at 6 M293518 degrees. A further object of the present invention is to provide a fast bidirectional switch, which has a shaft-axis column extending below the receiving member of the telescopic rod, and a magazine at the lower end of the shaft column, the shaft column can be inserted into the bag of the telescopic rod Inside the sleeve, and the switch system is disposed inside the remaining sleeve, so that the heart column can be penetrated and smashed, and the expansion and condensation action is performed in the bag sleeve. The center of the lower end surface of the bag sleeve is provided with a concave arc. The chamber is filled with a partial volume of the ball of the ball, so that the ball of the ball can be rotated, that is, when the ball does not slide to a certain position, it does not move at all, and the contact surface is completely absent. Conductive, but after sliding to a certain position, the spring is quickly bounced due to the tension effect, so it is pressed, and when the receiving member is pressed by an external force, the telescopic rod can be condensed and stretched. [Embodiment] Please refer to the fourth to seventh figures. This is a fast bidirectional switch.

The spring 144 and the shaft post 146 are arranged in a nested manner, and the pocket sleeve 143 is placed under the sleeve 143. A concave arc-shaped chamber 145 is disposed at the center of the end surface. The inside of the chamber is fitted with a ball ball 142, so that another volume of the ball 142 can protrude from the pocket sleeve. 7 M293518 I43 The lower end surface enables the _ball 142 to rotate for rapid sliding, so that the socket (4) can be pressed and extended in the same manner as the 143, and a base (four) is fixed under the door cover n. A groove m is disposed at a top surface of the seat 12, and the bottom surface of the groove 121 is provided with two symmetrical inclination angles, and the bottom surface of the groove 121 has an outwardly convex isosceles triangle shape, and the groove is formed in the groove The outer convex end of the bottom surface of the bottom surface of the bottom surface of the bottom surface of the bottom surface of the bottom surface of the bottom surface of the 121 is provided with a contact plate π.

Ϊ́5ι, the guide groove (5) is used for limiting sliding of the ball 146 in the telescopic rod 14, and the inclined surface of the groove i2i of the base 12 is provided with a conductive metal piece 15a, each conductive metal piece (5) are connected with a power cord 123, each of the power cords 123 - end extending to a side of the base 12; when the twitching plate 13 is translated, the telescopic flange 14 (5) of the receiving member 141 under the force of the twitching plate 13 The spring 144 is telescopically press-fitted so that the telescopic rod 14_ball 142 can slide in the guide groove 151_ of the thin plate 15, so that the contact plate 15 can be made on the opposite sides of the groove 121 of the base 12 The action of the seesaw, so that the contact plate 15 and the twitch plate 13 f 曰 1 can be rotated by the movement of the telescopic rod 14 to produce a diagonal press-fit positioning point switch, when the twitch plate 13 is outside the door-shaped cover 11 When moving, the fulcrum m on the twitching plate I3 moves toward the right side of the bump 152 of the contact plate 15, at which time the ball 142 of the telescopic rod 14 The slider is positioned on one end of the guide groove 151 of the contact plate 15, so that the conductive layer 1511 of the lower edge of the contact plate 15 can be in power communication with one of the conductive metal pieces i5a on the base 12; When the other end of the door cover u moves, the fulcrum 131 on the twitching plate 13 moves toward the left side of the bump 152 of the contact plate 15, at which time the telescopic rod 14 is squeezed and condensed by the twitching plate 13, and the damper plate 13 is moved inward to At the positioning position, the telescopic rod 14 and the contact plate 15 have an opposite inclination angle. At this time, the ball ball 142 of the telescopic rod 14 loses the positioning and restraint of one end side of the guide groove 151, and rapidly moves to the guide groove 151. The other end of the inner side is used as a slider positioning action, and at the same time, the contact plate 15 is inclined to the other end surface, and the conductive layer 1511 of the contact plate π is connected to the other conductive metal piece 15a to form a bidirectional conductive switch. ; in turn, the fast bidirectional 8 M293518 switch 1 has a fast switching power supply action of turning on or off. „t^〇, 2 is provided at the top of the second 21, the member 23 is provided with a sliding plate 23i under the triggering member 23, and the sliding plate 231 can be used in the guiding groove 211 under the translation of the pulling member 23.

To make the creation more progressive And practicality, and product comparison - comparative analysis is as follows: The use of the lack of: 1. The use of fast will have a late _, in _, f will lead the handle is indeed conductive, forming a discharge phenomenon, causing high heat and thermal oxidation, And the precision is not good. 2. When the button is connected or disconnected, it will produce an incompletely conductive state, because the system is detached or knotted. The spacing production produces a similar discharge phenomenon in the air like lightning, so it will inevitably produce quite high heat. If this is the case, it will inevitably cause deformation of the relevant components. In the same day, for the high heat phenomenon of the discharge, thermal oxidation will also occur, and accelerated contact will occur. The oxidative deterioration of the surface metal affects the service life of the switch. 3. Does not have practicality. Advantages of this creation: 1. Using the ball movement of the ball and the contact plate, the piston can quickly make the switch of the sluice π Control the action and prevent the liquid flowing from the body outlet to the pressure tank from flowing back. 2. When the ball moves to the positioning point, the rapid control action of the piston is activated, so that the fast bidirectional switch has precision. Control action. 9 M293518 3.
