Description

Technical Field

[0001] The present invention relates to the technical field of push switch assemblies, and in particular to a push switch assembly in an electrical control panel and an operation method thereof. Background Art

[0002] A push-button switch refers to a switch that uses a button to push a transmission mechanism to make a moving contact and a static contact connect or disconnect to achieve circuit switching. The push-button switch is a main control electrical appliance with a simple structure and wide application. In an electrical automatic control circuit, it is used to manually send a control signal to control contactors, relays, electromagnetic starters, etc.

[0003] For the existing push switch assemblies in electrical control panels, there are the following problems: 1. The number of push-button switches on some electrical control panels is very large. Therefore, for novice operators, it is very easy to have problems such as accidental touch or incorrect pressing during operation; 2. The existing push-button switches need to be pressed one by one by the operator to control the corresponding programs or processes inside the electrical appliance. This not only increases the labor time, but also different degrees of pressing will cause damage to the buttons. Summary of the Invention

[0004] The present invention aims to provide a push switch assembly in an electrical control panel and an operation method thereof to solve the problems raised in the above background art.

[0005] To achieve the above object, the present invention provides the following technical solution: A push switch assembly in an electrical control panel includes a mis-touch prevention mechanism for protecting the button and handling mis-touch;

[0006] A locking mechanism for fastening the door panel and the device;

A bent rod is squeezed and fitted to the outer side of the resilient stopper, and the end of the bent rod away from the resilient stopper is fixedly connected to the outer side of the hollow cylinder.

[0014] Preferably, an external rod is fixedly connected to the end of the plug-in board away from the bevel disk, and a pull handle is fixedly connected to the end of the external rod away from the plug-in board. End strips are symmetrically connected to both sides of the plug-in board, and a socket plate is fixedly connected to the outer side of the end strips. An electric telescopic rod is fixedly connected to the side of the socket plate away from the end strips, and a support plate is fixedly connected to the end of the electric telescopic rod away from the socket plate. The support plate is fixedly connected to the outer end face of the cover plate.

[0015] Preferably, the locking mechanism includes a curved panel, which is fixedly connected to the outer side of the cover plate. A fixed cylinder is fixedly installed on the side of the curved panel away from the cover plate. A protruding rod is slidably fitted inside the fixed cylinder, and the protruding rod penetrates through the surfaces of the closing door and the curved panel and extends into the control panel.

[0016] Preferably, an external attachment plate is fixedly connected to the outer end face of the protruding rod, and a spring is fixedly connected to the side of the external attachment plate close to the protruding rod. The end of the spring away from the external attachment plate is fixedly connected to the fixed cylinder. A first magnet is fixedly connected to the end of the protruding rod away from the external attachment plate, and a second magnet is provided at the end of the first magnet away from the protruding rod. The second magnet is arranged inside the control panel.

[0017] Preferably, the protection mechanism includes a shaft bracket, which is fixedly connected to the outer side of the closing door. A rotating shaft is rotatably connected to the inner side of the shaft bracket, and a rocker is fixedly connected to the outer side of the rotating shaft. A pull rod is fixedly connected to the top of the rocker, and a spring strip is fixedly connected to the bottom of the rocker. The end of the spring strip away from the rocker is fixedly connected to the closing door.

[0018] Preferably, a protective cover is fixedly connected to the outside of the closed door. An emergency button is arranged inside the protective cover. A protective piece is fixedly connected to the top of the emergency button. The top of the protective piece is in pressing fit with the rocker. A bottom rail is fixedly connected to the inside of the protective cover. A limiting plate is fixedly connected to the outside of the protective cover. A partition plate is slidably fitted to the top of the bottom rail. A first dust-proof plate and a second dust-proof plate are respectively fixedly connected to the upper and lower sides of the partition plate. An external joint is fixedly connected to the outside of the first dust-proof plate.

[0019] An operation method of a push-button switch assembly in an electrical control panel includes the following steps:

[0020] Step 1: The operator manually pushes the pull handle to the right, so that the external rod connected to the other end thereof will drive the plug board into the inside of the hollow cylinder. The inclined surface end of the plug board is in pressing fit with the inclined surface disc. Therefore, as the plug board extends into the inside of the hollow cylinder, the inclined surface disc will move inward along the inner chute and compress the return spring. At the same time, during the process of the plug board being inserted into the hollow cylinder, it will squeeze and compress the resilient piece. In addition, the second magnet fixedly connected to the side away from the resilient piece will extend into the inside of the hollow cylinder. The second magnet and the first magnet fixedly connected to the switch button are in a repulsive relationship. Therefore, under the repulsive force of the two, the switch button will decelerate the process of a certain program inside the control panel or reduce the power transmission. When the operator inserts the second magnet completely into the hollow cylinder, the repulsive force between the two magnets will be at the maximum stage at this time. Therefore, the switch button will be pressed down completely to turn off a certain program or power inside the control panel;

[0021] Step 2: By starting the electric telescopic rod, the end socket plate connected to the telescopic end thereof will move towards the hollow cylinder and squeeze the end strip. The end strip is symmetrically connected to both sides of the plug board. Therefore, the plug board will move towards the hollow cylinder and insert into it. At this time, the plug boards in this row will all be inserted into the hollow cylinder, so that a number of switch buttons are all controlled;

[0022] Step 3: The operator manually pulls the external attachment plate outwards, so that the extending rod connected to the inside thereof will move outwards along the fixed cylinder and stretch the spring. A first magnet is fixedly connected to the inner end of the extending rod and generates an attractive force with the second magnet arranged inside the control panel. Then the first magnet will move outwards and away from the second magnet. At this time, the closed door can rotate, so that the operator can operate the inside of the control panel;

[0023] Step 4: The operator manually pulls out the external connector, causing the No. 1 dust shield connected to the other end to move outward with the baffle plate, and then the baffle plate extends outward from the protective cover along the top of the bottom rail. At the same time, the emergency button is no longer limited and fixed. Then the operator manually pulls the pull rod upward, causing the seesaw fixed to its bottom to deflect counterclockwise through the rotating shaft and stretch the elastic strip. Then the other end of the seesaw squeezes the protective sheet downward, and the protective sheet is fixed to the top of the emergency button. Therefore, the emergency button is quickly pressed down to lock or close the entire control panel.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The No. 2 magnetic block and the No. 1 magnetic block fixedly connected to the switch button maintain a repulsive relationship. Therefore, the switch button, under the repulsive force of the two, slows down the progress of a program inside the control panel or reduces the amount of power delivered.

[0026] 2. The plug-in board will encounter a certain amount of resistance during the insertion process. If the force is increased, the tough resistance head will be compressed and the bent rod will be between the two tough resistance heads, allowing the operator to record how much the plug-in board is inserted into the hollow cylinder and how much repulsion is generated between the two magnetic blocks.

[0027] 3. When the insertion rod is extended outward, the cover plate will move to the left along the horizontal track through the slide bar. At this time, the operator can push the cover plate and make the accidental touch component away from the switch button, so that the operator can directly operate several switch buttons.

[0028] 4. The protective sheet is fixedly connected to the top of the emergency button and prevents the emergency button from being damaged and worn due to long-term pressing. Therefore, the emergency button will be pressed down quickly, thereby locking or closing the entire control panel. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0044] Next, in combination with the accompanying drawings and specific implementation manners, the present invention will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined with each other to form new embodiments. It should be known that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] Please refer to Figures 1 to 14 , the present invention provides a technical solution: As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , it includes a mis-touch mechanism 3 for protecting the button and handling mis-touch;

[0046] a locking mechanism 4 for fastening the door panel and the device;

[0047] a protection mechanism 5 for protecting special buttons;

[0048] The mis-touch mechanism 3, the locking mechanism 4 and the protection mechanism 5 are all installed on the closing door 2. The locking mechanism 4 is installed on the mis-touch mechanism 3. The end face of the closing door 2 is installed with a control panel 1 through a hinge.

[0049] Among them, the mis-touch mechanism 3 includes a horizontal rail 31 which is fixedly installed on the outside of the closing door 2. A slide bar 32 is slidably fitted inside the horizontal rail 31. The outer end face of the slide bar 32 is fixedly connected with a cover plate 33. A round hole 34 is opened on the outside of the cover plate 33. A mis-touch component 37 is fixedly installed on the side of the cover plate 33 away from the horizontal rail 31. A switch button 35 is arranged at the center of the round hole 34. The switch button 35 is installed on the control panel 1. One end of the switch button 35 away from the control panel 1 is fixedly connected with a first magnetic block 36.

[0050] The accidental touch component 37 includes a hollow cylinder 371, which is fixedly installed on the outer side of the cover plate 33. An inner sliding groove 372 is formed inside the hollow cylinder 371. A sliding disk 373 is slidably fitted inside the inner sliding groove 372. A return spring 374 is fixedly connected to the outer side of the sliding disk 373. One end of the return spring 374 away from the sliding disk 373 is fixedly connected to the inner side of the hollow cylinder 371. A plug-in plate 376 is inserted into the outer side of the hollow cylinder 371. The plug-in plate 376 penetrates into the inside of the hollow cylinder 371. A bevel disk 375 is extrusion-fitted to the inclined surface part of the plug-in plate 376. One end of the bevel disk 375 away from the plug-in plate 376 is fixedly connected to the sliding disk 373. A second magnetic block 377 is fixedly connected to the side of the plug-in plate 376 away from the bevel disk 375. A repulsive relationship is maintained between the first magnetic block 36 and the second magnetic block 377. At the same time, during the process of inserting the plug-in plate 376 into the inside of the hollow cylinder 371, it will squeeze and compress the resilient piece 378. In addition, the second magnetic block 377 fixedly connected to the side of the plug-in plate 376 away from the resilient piece 378 will extend into the inside of the hollow cylinder 371. A repulsive relationship is maintained between the second magnetic block 377 and the first magnetic block 36 fixedly connected to the switch button 35. Therefore, under the repulsive force of the two, the switch button 35 plays a role in decelerating the process of a certain program inside the control panel 1 or reducing the power transmission amount.

[0051] On one side of the plug-in board 376 away from the second magnetic block 377, a resilient piece 378 is fixedly connected. One end of the resilient piece 378 away from the plug-in board 376 is fixedly connected to the hollow cylinder 371. A top groove 3705 is formed at the top of the plug-in board 376. A resilient stopper 3706 is fixedly connected to the bottom of the top groove 3705. A bent rod 3707 is extrusion-fitted to the outside of the resilient stopper 3706. One end of the bent rod 3707 away from the resilient stopper 3706 is fixedly connected to the outside of the hollow cylinder 371. One end of the plug-in board 376 away from the inclined surface disk 375 is fixedly connected to an external connecting rod 379. One end of the external connecting rod 379 away from the plug-in board 376 is fixedly connected to a pull handle 370. By manually pushing the pull handle 370 to the right by the operator, the external connecting rod 379 connected to the other end thereof will drive the plug-in board 376 into the interior of the hollow cylinder 371. The inclined surface end of the plug-in board 376 is extrusion-fitted with the inclined surface disk 375, and the contact surfaces are all inclined surfaces. Therefore, as the plug-in board 376 extends into the interior of the hollow cylinder 371, the inclined surface disk 375 will move inward along the inner sliding groove 372 and compress the return spring 374. The return spring 374 functions to reset the sliding disk 373 and the inclined surface disk 375. In addition, the inclined surface disk 375 and the return spring 374 also function such that when someone accidentally touches the pull handle 370 from the side, the contact area between the plug-in board 376 and the inclined surface disk 375 will be very small. However, the plug-in board 376 is still inserted into the interior of the hollow cylinder 371. However, because the contact surface between the two is small, the frictional force is small, and the elastic tensile force of the return spring 374 is greater than the frictional force between the two. Eventually, the plug-in board 376 still extends outward from the interior of the hollow cylinder 371, thereby preventing the switch button 35 from being indirectly pressed, resulting in problems in subsequent procedures. At the same time, this design form can prevent the operator from accidentally touching the switch button 35 face-to-face. On both sides of the plug-in board 376, end strips 3701 are symmetrically connected. A socket plate 3702 is fixedly connected to the outside of the end strips 3701. One side of the socket plate 3702 away from the end strips 3701 is fixedly connected to an electric telescopic rod 3703. By activating the electric telescopic rod 3703, the end face socket plate 3702 connected to the telescopic end thereof will move towards the hollow cylinder 371 and squeeze the end strips 3701. The end strips 3701 are symmetrically connected to both sides of the plug-in board 376. Therefore, the plug-in board 376 will move towards the hollow cylinder 371 accordingly and be inserted into its interior. At this time, the plug-in boards 376 in this row will all be inserted into the hollow cylinder 371, thereby enabling a plurality of switch buttons 35 in the row to be controlled without the need for individual adjustment. One end of the electric telescopic rod 3703 away from the socket plate 3702 is fixedly connected to a support plate 3704, and the support plate 3704 is fixedly connected to the outer end face of the cover plate 33.When the operator fully inserts the second magnetic block 377 into the hollow cylinder 371, the repulsive force between the two magnetic blocks will reach its maximum stage. At this time, the switch button 35 will be fully pressed down, thus shutting down a certain program or power supply inside the control panel 1. Additionally, a resilient stopper 3706 is provided at the top of the plug-in board 376, and the number of resilient stoppers 3706 is several, and they are respectively in mutual extrusion fit with the bent rods 3707. Therefore, when the plug-in board 376 extends into the hollow cylinder 371, the bent rods 3707 will squeeze the resilient stoppers 3706, causing the plug-in board 376 to encounter a certain resistance during the extension process. If more force is applied, the resilient stoppers 3706 will compress and the bent rods 3707 will be located between the two resilient stoppers 3706, thus enabling the operator to record how much the plug-in board 376 has been inserted into the hollow cylinder 371 and how much repulsive force is generated between the two magnetic blocks.

[0052] As Figure 9 , Figure 10 and Figure 11 shown, the locking mechanism 4 includes a curved panel 41, which is fixedly connected to the outer side of the cover plate 33. A fixed cylinder 42 is fixedly installed on the side of the curved panel 41 away from the cover plate 33. A retractable rod 43 is slidably fitted inside the fixed cylinder 42. The retractable rod 43 penetrates through the surfaces of the closing door 2 and the curved panel 41 respectively and extends into the control panel 1. An outer attaching plate 44 is fixedly connected to the outer end face of the retractable rod 43. A spring 45 is fixedly connected to the side of the outer attaching plate 44 close to the retractable rod 43. The end of the spring 45 away from the outer attaching plate 44 is fixedly connected to the fixed cylinder 42. A first magnet 46 is fixedly connected to the end of the retractable rod 43 away from the outer attaching plate 44. A second magnet 47 is provided at the end of the first magnet 46 away from the retractable rod 43, and the second magnet 47 is arranged inside the control panel 1. By manually pulling the outer attaching plate 44 outward by the operator, the retractable rod 43 connected to its inner side will move outward along the fixed cylinder 42 and stretch the spring 45. The inner end of the retractable rod 43 is fixedly connected with a first magnet 46, which generates an attractive force with the second magnet 47 arranged inside the control panel 1. Then the first magnet 46 will move outward and away from the second magnet 47. At this time, the closing door 2 can rotate, thus enabling the operator to operate the inside of the control panel 1. Additionally, the retractable rod 43 also plays a role in limiting the cover plate 33. When the retractable rod 43 extends outward, the cover plate 33 will move leftward along the horizontal rail 31 through the slide bar 32. At this time, the operator can push the cover plate 33 and move the mis-touch component 37 away from the switch button 35, so that the operator can directly operate a number of switch buttons 35.

[0053] As Figure 12 , Figure 13and Figure 14 As shown, the protection mechanism 5 includes an axis bracket 51, the axis bracket 51 is fixedly connected to the outer side of the closed door 2, the inner side of the axis bracket 51 is rotatably connected to a rotating shaft 52, the outer side of the rotating shaft 52 is fixedly connected to a seesaw 53, the top of the seesaw 53 is fixedly connected to a pull rod 54, the bottom of the seesaw 53 is fixedly connected to an elastic bar 55, the end of the elastic bar 55 away from the seesaw 53 is fixedly connected to the closed door 2, the outer side of the closed door 2 is fixedly connected to a protective cover 503, and the interior of the protective cover 503 is provided with a tight Emergency button 57, the top of the emergency button 57 is fixedly connected with a protective sheet 56, the top of the protective sheet 56 is squeezed and fitted with the rocker 53, the inner side of the protective cover 503 is fixedly connected with a bottom rail 502, the outer side of the protective cover 503 is fixedly connected with a limiting plate 504, the top of the bottom rail 502 is slidably adapted with a blocking plate 58, the upper and lower sides of the blocking plate 58 are respectively fixedly connected with a No. 1 dustproof plate 59 and a No. 2 dustproof plate 50, and the outer side of the No. 1 dustproof plate 59 is fixedly connected with an external joint 501. The operator first manually pulls out the external connector 501, causing the No. 1 dust plate 59 connected to the other end to move outward with the blocking plate 58, and then the blocking plate 58 extends outward from the protective cover 503 along the top of the bottom rail 502, and the emergency button 57 is no longer limited and fixed. Then the operator manually pulls the pull rod 54 upward, so that the seesaw 53 fixedly connected to the bottom thereof is deflected counterclockwise through the rotating shaft 52, and the elastic strip 55 is stretched, and then the other end of the seesaw 53 is pressed against the protective sheet 56 is squeezed downward, wherein the protective sheet 56 is fixedly connected to the top of the emergency button 57 and serves to prevent the emergency button 57 from being damaged and worn due to long-term pressing. Therefore, the emergency button 57 will be pressed down quickly, thereby locking or closing the entire control panel 1. At the same time, when the emergency button 57 needs to be operated, the blocking plate 58 extends outward and the pull rod 54 is pulled upward. Both of them play an indispensable role, and also prevent the operator's hands and legs from accidentally touching it.

[0054] When the present invention is in use: First, the operator manually pushes the pull handle 370 to the right, causing the external rod 379 connected to the other end thereof to drive the plug-in board 376 into the interior of the hollow cylinder 371. The inclined surface end of the plug-in board 376 is in extrusion fit with the inclined surface disc 375. Therefore, as the plug-in board 376 extends into the interior of the hollow cylinder 371, the inclined surface disc 375 will move inward along the inner chute 372 and compress the return spring 374. At the same time, during the process of the plug-in board 376 being inserted into the interior of the hollow cylinder 371, it will squeeze and compress the resilient piece 378. In addition, the second magnet 377 fixedly connected to the side away from the resilient piece 378 will extend into the interior of the hollow cylinder 371, and there is a repulsive relationship between the second magnet 377 and the first magnet 36 fixedly connected to the switch button 35. Therefore, under the repulsive force of the two, the switch button 35 will decelerate the process of a certain program inside the control panel 1 or reduce the power transmission amount. When the operator fully inserts the second magnet 377 into the interior of the hollow cylinder 371, the repulsive force between the two magnets will be at the maximum stage at this time. Therefore, the switch button 35 will be fully pressed down to achieve the complete shutdown of a certain program or power inside the control panel 1.

[0055] By starting the electric telescopic rod 3703, the end face socket plate 3702 connected to the telescopic end thereof will move towards the hollow cylinder 371 and squeeze the end face strip 3701. The end face strip 3701 is symmetrically connected to both sides of the plug-in board 376. Therefore, the plug-in board 376 will move towards the hollow cylinder 371 accordingly and be inserted into its interior. At this time, the plug-in boards 376 in this row will all be inserted into the hollow cylinder 371, causing several switch buttons 35 to be controlled.

[0056] By the operator manually pulling the external attachment plate 44 outward, the extending rod 43 connected to the inner side thereof will move outward along the fixed cylinder 42 and stretch the spring 45. The inner end of the extending rod 43 is fixedly connected with a first magnet 46, which generates an attractive force with the second magnet 47 arranged inside the control panel 1. Immediately afterwards, the first magnet 46 will move outward and away from the second magnet 47. At this time, the closing door 2 can rotate, enabling the operator to operate the interior of the control panel 1.

[0057] The operator first manually pulls out the external connector 501, causing the No. 1 dust plate 59 connected to the other end to move outward with the blocking plate 58, and then the blocking plate 58 extends outward from the protective cover 503 along the top of the bottom rail 502, and the emergency button 57 is no longer limited and fixed. Then the operator manually pulls the pull rod 54 upward, so that the rocker 53 fixedly connected to its bottom will deflect counterclockwise through the rotating shaft 52 and stretch the elastic bar 55.
