Description
Technical Field
[0001] The present invention relates to the technical field of button switches, and more particularly to a switch trigger device for an electric tool. Background Art
[0002] A touch switch is an electronic switch that belongs to the category of electronic components. It is also called a push button switch. It first appeared in Japan [called a sensitive switch]. When used, the switch function is closed and connected by applying pressure in the direction of the switch operation under the condition of the operating force. When the pressure is removed, the switch is disconnected. Its internal structure relies on the force change of the metal spring to achieve on and off. The touch switch has the advantages of small contact resistance, precise operating force error, and diversified specifications. It is widely used in electronic equipment and white appliances.
[0003] Most of the existing switch trigger devices realize on-off by applying force to the metal spring. Since the metal spring moves back and forth inside the switch without a limit device, it may slip when used for a long time, resulting in poor contact.
[0004] Most of the existing switch triggering devices have complex structures and complicated internal components. They are inconvenient to trigger the switch and are easy to be damaged. They waste manpower and costs during manufacturing and have certain limitations during use.
[0005] Existing patent 1: The Chinese patent with the authorization publication number CN215731406U discloses a limit switch trigger device. By adding a slider, a slide plate, a fixing plate and an elastic device, the second spring and the contact block at the side end of the slider can be limited. The slider reciprocates in the slide groove to avoid the movement of the contact point caused by long-term sliding, thereby avoiding affecting the normal use of the trigger device.
[0006] Although this limit switch trigger device can prevent the contact point from moving due to long-term sliding, it does not have an anti-mistouch function during actual use. Especially in the field of information technology, mistriggering the function key may cause the process to be interrupted unexpectedly, causing the computer to perform shutdown, reset, restart, CD ejection and other operations without subjective intention, thereby causing program interruption, file loss, hardware damage and even illegal loss. Especially for network servers, since the server is in operation at any time and must be maintained frequently, during the maintenance process, the server is in the power-on state, and the maintenance personnel have many actions during the maintenance process. If the power is cut off or the computer is restarted due to an accidental touch, it will cause considerable potential danger to the server and the computer. Summary of the invention
[0007] In view of the problems existing in the prior art, the purpose of the present invention is to provide a switch trigger device for an electric tool, which can prevent accidental touches and cause irreparable damage.
[0008] To solve the above problems, the present invention adopts the following technical solutions.
[0009] A switch trigger device for an electric tool comprises a shell, a handle is arranged on the upper side of the shell, a rotating shaft is arranged on the lower end face of the handle, a turntable is arranged on the inner upper side of the shell, the rotating shaft extends to the inside of the shell and is fixedly connected to the turntable, a transmission mechanism is arranged on the inner upper side of the shell, a switching mechanism is arranged inside the transmission mechanism, an anti-mistouch mechanism is arranged on the lower side of the switching mechanism, the transmission mechanism comprises a transmission column fixedly installed on the lower end face of the turntable, a sleeve rotatably connected to the inner lower end face of the shell, the transmission column and the sleeve are slidably connected, a spring is fixedly installed between the transmission column and the inner lower end face of the sleeve, the switching mechanism rotates after pressing the handle to connect the power supplies between different circuits to achieve different effects, and the anti-mistouch mechanism limits the switching mechanism to prevent the switching mechanism from falling and connecting different circuits.
[0010] When the device needs to be used, first turn the handle to rotate the turntable carrying the billiard ball one. When the billiard ball one rotates to the top of the slot, press the handle to make the turntable carrying the two sets of billiard balls one descend and fall into the lower part of the shell through the slot, and then turn the handle.
[0011] Furthermore, the switching mechanism includes a fixed ring fixedly installed on the inner wall of the outer shell, an inner cavity opened inside the turntable, a sliding column slidably connected to the interior of the inner cavity, a connecting ring 2 fixedly installed on the outer surface of the sliding column, a connecting ring 1 fixedly installed on the inner wall of the inner cavity, a spring 1 fixedly installed between the connecting ring 1 and the connecting ring 2, and the spring set is arranged on the outer surface of the sliding column.
[0012] The turntable carrying billiard ball one rotates until the two groups of billiard balls one collide with the corresponding billiard balls two. At this time, the billiard balls one are pressed by force against the sliding column, so that the contact point one on the sliding column and the contact point two on the connecting line contact each other. In this way, the current in the cables on the two corresponding groups of billiard balls two can be connected through the billiard ball one and the connecting line to achieve the specified task instructions.
[0013] Furthermore, a billiard ball 1 is fixedly mounted on one end of the slide column, a contact 2 is fixedly mounted on the other end of the slide column, a contact 2 is fixedly mounted on the inner lower end surface of the inner cavity, and a notch is provided on the upper end surface of the fixing ring corresponding to the billiard ball 1.
[0014] When the line needs to be disconnected, the above structure is reversed, and the billiard ball 1 is separated from the billiard ball 2. Under the action of spring 1, the slide column returns to its original position, and contact 1 is disconnected from contact 2. When billiard ball 1 moves to the position of the slot,
[0015] Furthermore, the inner cavity, connecting ring 1, connecting ring 2, spring 1, contact 1, contact 2 and billiard ball 1 are each provided in two groups, with an angle of 120 degrees between them, and a connecting wire is fixedly installed between the two groups of contact 2.
[0016] Under the action of spring 2, the turntable will be driven to rise and then return to its original state.
[0017] Furthermore, a billiard ball 2 is fixedly installed on the lower inner wall of the shell corresponding to the billiard ball 1, a cable is fixedly installed at the rear end of the billiard ball 2, and three groups of billiard ball 2, slots and cables are correspondingly arranged and dispersed in a ring shape.
[0018] This scheme sets up a transmission mechanism and a switching mechanism. By pressing the handle, the billiard ball 1 slides down through the slot, and then the handle is turned to make the turntable carry two groups of billiard balls 1 to rotate. The two groups of billiard balls 1 contact with the two corresponding groups of billiard balls 2 respectively, and when the collision makes the contact point 1 contact the contact point 2, the corresponding cable circuit will be connected and normal operation will be performed.
[0019] Furthermore, the anti-mistouch mechanism includes a cavity opened inside the shell, a slide groove is opened inside the cavity, a slip ring is slidably connected inside the slide groove, and a swivel is fixedly installed on the outer surface of the slip ring.
[0020] Furthermore, billiard balls three are fixedly mounted on the inner wall of the rotating ring, and three groups of billiard balls three are arranged corresponding to the three groups of notches and are dispersedly arranged in a ring shape.
[0021] When the device is not needed, the anti-accidental touch mechanism can be opened to avoid accidental touch of the device, and the slip ring can be displaced with the billiard ball three by twisting the ring.
[0022] Furthermore, a through hole is provided between the notch and the cavity, a transmission rod is slidably connected inside the through hole, a connecting ring three is fixedly installed on the outer surface of the transmission rod, and a spring three is fixedly installed between the connecting ring three and the inner wall of the cavity.
[0023] The billiard ball three and the billiard ball four on the transmission rod collide with each other to transmit, so that the transmission rod slides inside the through hole and is inserted into the inside of the notch to block the notch.
[0024] Furthermore, a billiard ball four is fixedly installed at the left end of the transmission rod corresponding to the billiard ball three, and the billiard ball one, billiard ball two, billiard ball three and billiard ball four are all made of elastic material.
[0025] By maintaining the squeezed state between billiard ball three and billiard ball four, the slot can be blocked, so that the turntable cannot carry billiard ball one to descend through the slot to connect the line.
[0026] This solution sets up an anti-mistouch mechanism, which causes billiard ball three to hit billiard ball four by rotating a swivel, thereby inserting a transmission rod into the inside of the slot, making it impossible for billiard ball one to fall through the slot, thereby connecting the circuits between the groups of cables and avoiding irreparable losses caused by mistouch when not in use.
[0027] Furthermore, the through hole, the transmission rod, the third connecting ring, the third spring and the fourth billiard ball are all fixedly installed in three groups and are dispersedly arranged in a ring shape.
[0028] Compared with the prior art, the present invention has the following beneficial effects:
[0029] (1) This solution provides an anti-accidental touch mechanism. By rotating the rotating ring, the billiard ball three hits the billiard ball four, thereby inserting the transmission rod into the inside of the slot, so that the billiard ball one cannot fall through the slot, connecting the circuits between the groups of cables, and avoiding irreparable losses caused by accidental touch when not in use;
[0030] (2) This scheme sets up a transmission mechanism and a switching mechanism. By pressing the handle, the billiard ball 1 slides down through the slot, and then the handle is turned to make the turntable carry the two groups of billiard balls 1 to rotate. The two groups of billiard balls 1 contact the two corresponding groups of billiard balls 2 respectively, and when the collision makes the contact point 1 contact the contact point 2, the corresponding cable circuit will be connected and normal operation will be performed.

[0044] By adopting the above technical scheme, the present scheme sets a transmission mechanism and a switching mechanism, and by pressing the handle 2, the billiard ball 13 slides down through the slot 14, and then the handle 2 is turned to make the turntable 4 carry two groups of billiard balls 13 to rotate, and the two groups of billiard balls 13 contact each other with the two corresponding groups of billiard balls 2 18 respectively, and when the collision makes the contact 11 contact the contact 2 30, the corresponding cable 19 circuit will be connected to perform normal operation. Specifically: first, when it is necessary to use the present device, the handle 2 is first turned to make the turntable 4 carry the billiard ball 13 to rotate, and when the billiard ball 13 rotates to the top of the slot 14, the handle 2 is pressed to make the turntable 4 carry the two groups of billiard balls 13 to descend, and fall into the lower part of the shell 1 through the slot 14, and then Then, the handle 2 is turned to rotate the turntable 4 carrying the billiard balls 13 until the two groups of billiard balls 13 collide with the corresponding billiard balls 2 18. At this time, the billiard balls 13 are pressed by the sliding column 8, so that the contact 11 on the sliding column 8 and the contact 2 30 on the connecting line 12 contact each other, so that the current in the cables 19 on the two corresponding groups of billiard balls 2 18 can be connected through the billiard balls 13 and the connecting line 12 to achieve the specified task instructions. When it is necessary to disconnect the line, the above structure is reversed, and the billiard balls 13 are separated from the billiard balls 2 18. Under the action of the spring 10, the sliding column 8 returns to its original position, and the contact 11 is disconnected from the contact 2 30. When the billiard balls 13 move to the position of the slot 14, the turntable 4 is driven to rise under the action of the spring 2 17 to return to its original state.
[0045] like Figure 5 As shown, the anti-mistaken touch mechanism includes a cavity 20 opened inside the housing 1, a slide groove 21 is opened inside the cavity 20, a slip ring 23 is slidably connected inside the slide groove 21, a swivel 22 is fixedly installed on the outer surface of the slip ring 23, and a billiard ball 24 is fixedly installed on the inner wall of the swivel 22. The billiard ball 24 is provided in three groups corresponding to the three groups of notches 14 and is dispersedly arranged in an annular shape. A through hole 25 is provided between the notch and the cavity 20, and a transmission is slidably connected inside the through hole 25. Rod 26, a connecting ring three 27 is fixedly installed on the outer surface of the transmission rod 26, a spring three 28 is fixedly installed on the connecting ring three 27 and the inner wall of the cavity 20, a billiard ball four 29 is fixedly installed on the left end of the transmission rod 26 corresponding to the billiard ball three 24, the billiard ball one 13, the billiard ball two 18, the billiard ball three 24 and the billiard ball four 29 are all made of elastic material, and the through hole 25, the transmission rod 26, the connecting ring three 27, the spring three 28 and the billiard ball four 29 are all fixedly installed in three groups and are dispersedly arranged in a ring shape.
[0046] By adopting the above technical scheme, the existing equipment has no anti-mistouch function during actual use, especially in the field of information technology. Mistakenly triggering the function key may cause the process to be interrupted unexpectedly, and the computer will be shut down, reset, restart, eject the CD and other operations without subjective intention, thus causing program interruption, file loss, hardware damage and other situations, and even illegal loss. Especially for network-type servers, since the server is in operation at any time and must be maintained regularly, the server is turned on during maintenance. The maintenance personnel perform many actions during the maintenance process. If the power is cut off or the computer is restarted due to an accidental touch, it will cause considerable potential danger to the server and the computer. Therefore, this scheme sets an anti-mistouch mechanism, which is subjected to the rotating ring 22, so that the billiard ball three 24 hits the billiard ball four 29, thereby inserting the transmission rod 26 into the inside of the slot 14, so that the billiard ball one 13 cannot fall through the slot 14, and the circuits between the groups of cables 19 are connected to avoid When not in use, irreparable losses caused by accidental touch can be avoided. Specifically: when the device is not needed, the anti-accidental touch mechanism can be opened to avoid accidental touch of the device. By twisting the ring 22, the slip ring 23 carries the billiard ball 3 24 to move, and the billiard ball 3 24 and the billiard ball 4 29 on the transmission rod 26 collide with each other for transmission, so that the transmission rod 26 slides inside the through hole 25 and is inserted into the slot 14 to block the slot 14. The squeezing state between the billiard ball 3 24 and the billiard ball 4 29 is maintained to block the slot 14. In this way, the turntable 4 cannot carry the billiard ball 13 to descend through the slot 14 to connect the line.
[0047] Instructions for use: First, when the device needs to be used, first turn the handle 2 to rotate the turntable 4 carrying the billiard ball 13. When the billiard ball 13 rotates to the top of the slot 14, press the handle 2 to make the turntable 4 carrying the two groups of billiard balls 13 descend and fall into the lower half of the housing 1 through the slot 14. Then turn the handle 2 to rotate the turntable 4 carrying the billiard ball 13 until the two groups of billiard balls 13 collide with the corresponding billiard balls 2 18. At this time, the billiard ball 13 is forced to squeeze the sliding column 8, so that the contact 11 on the sliding column 8 and the contact 2 30 on the connecting line 12 contact each other, so that the current in the cable 19 on the two groups of billiard balls 2 18 can be connected through the billiard ball 13 and the connecting line 12 to achieve the specified task instruction. When the line needs to be disconnected, the above structure is reversed, and The billiard ball 13 is separated from the billiard ball 2 18, and under the action of the spring 10, the sliding column 8 returns to its original position, and the contact 11 is disconnected from the contact 2 30. When the billiard ball 13 moves to the position of the slot 14, the turntable 4 is driven to rise under the action of the spring 2 17 and restored to its original state. When the device is not needed, the anti-mistouch mechanism can be opened to avoid accidental touch of the device. The slip ring 23 is used to carry the billiard ball 3 24 for displacement through the torsion ring 22, and the billiard ball 3 24 and the billiard ball 4 29 on the transmission rod 26 collide with each other for transmission, so that the transmission rod 26 slides inside the through hole 25 and is inserted into the slot 14 to block the slot 14. The squeezing state between the billiard ball 3 24 and the billiard ball 4 29 is maintained to block the slot 14. In this way, the turntable 4 cannot carry the billiard ball 13 through the slot 14 to descend and connect the line.
[0048] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
