Description
Technical Field
[0001] The utility model relates to the technical field of instant stop switches, in particular to an instant stop switch with an anti-accidental touch structure. Background Art
[0002] A stop switch is an emergency stop switch used to stop electrical equipment in an emergency. It is typically installed on the control panel of mechanical or electrical equipment and can immediately cut off power to the equipment in an emergency, ensuring the safety of personnel and equipment. A stop switch is clearly marked, usually a red button or switch, to facilitate quick identification and operation in an emergency. When pressed, it immediately cuts off the power signal and halts the equipment. Some stop switches also feature a forced disconnect function, effectively shutting off power even if the switch is stuck or damaged. Stop switches are widely used in various equipment and industries, such as machinery manufacturing, automated production lines, and electrical equipment. They are a crucial device for ensuring the safety of equipment and personnel, quickly stopping equipment in an emergency and preventing accidents.
[0003] During production in the workshop, the equipment on the production line needs to activate the stop switch for emergency management to ensure the safe production of the production line. Therefore, the stop switch of the production line is very important, and the position of the switch will also be set in a position that is relatively easy to operate. However, because of this, workshop staff may pull the line connected to the switch, or accidentally touch the switch, causing the equipment to stop working when it is not necessary, causing losses. Utility Model Content
[0004] The purpose of the present invention is to provide an instant stop switch with an anti-accidental touch structure to solve the problems raised in the above background technology.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a stop switch with an anti-accidental-touch structure, comprising a housing and a switch paddle, a control unit provided at the bottom of the housing, a protective unit provided between the switch paddle and the housing, and the control unit comprising:
[0006] A connecting ring, wherein the top surface of the connecting ring is fixedly connected to the bottom surface of the housing, and the bottom surface of the connecting ring is fixedly connected to a connecting post, and the connecting post passes through and is threadedly connected to a connecting cap. The connecting cap is twisted to gradually tighten the connecting cap with the connecting post. During the process of tightening the connecting cap with the connecting post, the connecting cap gradually moves toward the connecting ring;
[0007] A groove is provided on the surface of the connecting ring, a moving block is slidably connected to the inner side of the groove, and a clamping block is fixedly connected to the moving block on one side of the axis of the connecting ring;
[0008] A rotating ring is passed through the top surface of the connecting cap, and the rotating ring is rotatably connected to the connecting cap. The top surface of the rotating ring is fixedly connected to the insertion rod. When the connecting cap rotates and approaches the connecting ring, the rotating ring will rotate relative to the connecting cap, and the insertion rod will gradually be inserted into the groove. A slot is provided on the top surface of the insertion rod.
[0009] Preferably, the right side of the moving block is an inclined surface, and a notch is provided on the inclined surface of the moving block, so that the spring 1 is tightened when the moving block moves.
[0010] Preferably, a positioning rod passes through the inner side of the notch on the right side of the moving block, and the positioning rod is slidably connected to the moving block. When the connecting line needs to be removed, the connecting cap is loosened so that the insertion rod no longer conflicts with the inclined surface of the moving block, and the tightened spring pulls back the moving block for a while and resets it.
[0011] Preferably, a spring 1 is fixedly connected to the inner surface of the notch on the right side of the moving block, and an end of the spring 1 away from the moving block is fixedly connected to the inner side of the groove.
[0012] Preferably, the protective part includes a connecting block, which is fixedly connected to the inner side of the switch paddle. A circular hole is opened on the side of the connecting block close to the shell. A square rod passes through the inner side of the circular hole. The square rod passes through and is fixedly connected to a square plate. A spring 2 is fixedly connected between the square plate and the inner side of the circular hole.
[0013] Preferably, a support rod is fixedly connected to the surface of the shell, and a clamp is fixedly connected to the left side of the support rod. Pulling the switch paddle directly downward will cause the square rod to hit the inner side of the clamp so that the switch paddle cannot be pulled down. The support rod passes through and is slidably connected to a reset block. A spring three is fixedly connected between the reset block and the shell. When it is necessary to stop, first push the switch paddle upward for a distance, so that the connecting block drives the square rod to hit the reset block, and the square rod will pull the reset block to embed into the right side of the clamp.
[0014] Preferably, the insertion rod passes through the groove and is slidably connected, and the top surface of the insertion rod is an arc-shaped surface. When the arc-shaped surface of the insertion rod contacts the inclined surface of the moving block, it will force the moving block to slide along the groove toward the axis of the connecting ring, and the moving block will push the clamping block to clamp the connecting line.
[0015] Compared with the prior art, the present invention provides an instant stop switch with an anti-accidental touch structure, which has the following beneficial effects:
[0016] 1. The instant stop switch with an anti-accidental-touch structure, when the connecting cap is twisted, the connecting cap is gradually tightened with the connecting column. During the process of tightening the connecting cap and the connecting column, the connecting cap will gradually move toward the direction of the connecting ring. However, because the top surface of the connecting cap penetrates and rotates to be connected with a rotating ring, and the insertion rod is inserted into the groove and slidably connected, when the connecting cap rotates and approaches the connecting ring, the rotating ring will rotate relative to the connecting cap, and the insertion rod will gradually be inserted into the groove. When the curved surface of the insertion rod hits the inclined surface of the moving block, it will force the moving block to slide along the groove toward the axis of the connecting ring, and the moving block will push the clamping block to clamp the connecting line, preventing the staff from accidentally pulling the connection line between the production line equipment and the switch, causing the switch to fail.
[0017] 2. The instant stop switch with an anti-accidental touch structure has a structure where, when the switch paddle is not pulled down, the initial position of the clamp head is on the left side of the square rod. At this time, directly pulling the switch paddle downward will cause the square rod to hit the inner side of the clamp head, making the switch paddle unable to be pulled down, preventing the staff from accidentally touching the switch and causing the production line equipment to stop working when it is not necessary to stop. However, when it is necessary to stop the machine, first push the switch paddle upward for a distance so that the connecting block drives the square rod to hit the reset block. However, spring three will push the reset block tightly, causing the reset block to hit the square rod and retract into the circular hole. Then, pull the switch paddle downward, and the square rod will pull the reset block into the right side of the clamp head. When the switch paddle is continued to be pulled, the square rod no longer hits the inner side of the clamp head, but hits the inclined surface of the reset block, causing the square rod to retract into the circular hole. The clamp head no longer hits the square rod under the engagement of the reset block, so that the switch paddle can be pulled down to stop the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] like Figures 1-6 As shown, the utility model provides a technical solution: an instant stop switch with an anti-accidental touch structure, comprising a shell 1 and a switch paddle 4, a control part 2 is provided at the bottom of the shell 1, a protective part 3 is provided between the switch paddle 4 and the shell 1, and the control part 2 includes: a connecting ring 21, a connecting column 22, a connecting cap 23, a groove 24, a moving block 25, a clamping block 26, a notch 27, a positioning rod 28, a spring 29, a rotating ring 210, an insertion rod 211, and a slot 212.
[0026] The top surface of the connecting ring 21 is fixedly connected to the bottom surface of the shell 1. The bottom surface of the connecting ring 21 is fixedly connected to the connecting column 22. The connecting column 22 passes through and is threadedly connected to the connecting cap 23. First, the control line in the production line equipment passes through the connecting cap 23, the connecting column 22 and the connecting ring 21, and is connected to the switch element in the shell 1. Finally, the connecting cap 23 is screwed to gradually tighten the connecting cap 23 with the connecting column 22. During the process of tightening the connecting cap 23 with the connecting column 22, the connecting cap 23 will gradually move toward the direction of the connecting ring 21. The groove 24 is opened on the surface of the connecting ring 21, and the inner side of the groove 24 is slidably connected to the moving block 2 5. The movable block 25 is located on one side of the axis of the connecting ring 21 and is fixedly connected to a clamping block 26. The top surface of the connecting cap 23 is penetrated by a rotating ring 210, which is rotatably connected to the connecting cap 23. The top surface of the rotating ring 210 is fixedly connected to a rod 211. Because the top surface of the connecting cap 23 penetrates and is rotatably connected to the rotating ring 210, and the rod 211 is inserted into the groove 24 and slidably connected, as the connecting cap 23 rotates and approaches the connecting ring 21, the rotating ring 210 rotates relative to the connecting cap 23, gradually inserting the rod 211 into the groove 24. The top surface of the rod 211 is provided with a slot 212. The right side of the movable block 25 is inclined, and the inclined portion of the movable block 25 is provided with a notch 27. As the movable block 25 moves, it tightens the spring 1 29. The slot 212 and the notch 27 are offset from the spring 1 29 and the positioning rod 28, preventing motion interference and ensuring the normal movement of the movable block 25. A positioning rod 28 extends through the inside of the notch 27 on the right side of the movable block 25. This rod 28 is slidably connected to the movable block 25. To remove the connecting cable, the connecting cap 23 is loosened so that the insertion rod 211 no longer interferes with the inclined surface of the movable block 25. The tensioned spring 1 29 then pulls the movable block 25 back and resets it. A spring 1 29 is fixedly connected to the inside surface of the notch 27 on the right side of the movable block 25. The end of the spring 1 29, facing away from the movable block 25, is fixedly connected to the inside of the groove 24. The protective part 3 includes a connecting block 31, which is fixedly connected to the inner side of the switch paddle 4. A circular hole 32 is opened on the side of the connecting block 31 close to the shell 1, and a square rod 33 passes through the inner side of the circular hole 32. When the switch paddle 4 continues to be pulled, the square rod 33 no longer conflicts with the inner side of the clamping head 37, but conflicts with the inclined surface of the reset block 38, causing the square rod 33 to shrink into the circular hole 32, so that the clamping head 37 no longer conflicts with the square rod 33 under the engagement of the reset block 38, so that the switch paddle 4 can be pulled down to stop the equipment. The square rod 33 passes through and is fixedly connected to the square plate 34, and a spring 2 35 is fixedly connected between the square plate 34 and the inner side of the circular hole 32.The surface of the housing 1 is fixedly connected to a support rod 36, and a clamping head 37 is fixedly connected to the left side of the support rod 36. When the switch paddle 4 is not pulled down, the initial position of the clamping head 37 is on the left side of the square rod 33. At this time, pulling the switch paddle 4 directly downward will cause the square rod 33 to hit the inner side of the clamping head 37, so that the switch paddle 4 cannot be pulled down. The support rod 36 passes through and is slidably connected to a reset block 38. A spring 39 is fixedly connected between the reset block 38 and the housing 1. When it is necessary to stop, first push the switch paddle 4 upward for a distance, so that the connecting block 31 drives the square rod 33 to hit the reset block 38, but the spring 39 The reset block 38 will be pushed tightly, causing the reset block 38 to contact the square rod 33 and be retracted into the round hole 32, and then the switch paddle 4 will be pulled downward, and the square rod 33 will pull the reset block 38 to embed into the right side of the clamping head 37. The insertion rod 211 passes through the groove 24 and is slidably connected, and the top surface of the insertion rod 211 is an arc-shaped surface. When the arc-shaped surface of the insertion rod 211 contacts the inclined surface of the moving block 25, it will force the moving block 25 to slide along the groove 24 toward the axis of the connecting ring 21, and the moving block 25 will push the clamping block 26 to clamp the connecting line to prevent the staff from accidentally pulling the connection line between the production line equipment and the switch, causing the switch to fail.
[0027] Based on the above embodiment, first, the control line in the production line equipment is passed through the connecting cap 23, the connecting column 22 and the connecting ring 21, and connected to the switch element in the housing 1. Finally, the connecting cap 23 is screwed to gradually tighten the connecting cap 23 with the connecting column 22. During the process of tightening the connecting cap 23 with the connecting column 22, the connecting cap 23 will gradually move toward the direction of the connecting ring 21. However, because the top surface of the connecting cap 23 is penetrated and rotatably connected with the rotating ring 210, and the insertion rod 211 is inserted into the groove 24 and slidably connected, when the connecting cap 23 rotates and approaches the connecting ring 21, the rotating ring 210 will rotate relative to the connecting cap 23, and the insertion rod 211 will gradually be inserted into the groove 24 When the curved surface of the insertion rod 211 conflicts with the inclined surface of the moving block 25, the moving block 25 will be forced to slide along the groove 24 toward the axis of the connecting ring 21, and the moving block 25 will push the clamping block 26 to clamp the connecting line to prevent the staff from accidentally pulling the production line equipment and the switch connection line, causing the switch to fail. When the moving block 25 moves, the spring 1 29 will be tightened, and the slot 212 and the notch 27 will be staggered with the spring 1 29 and the positioning rod 28, which will not cause movement interference, ensuring the normal movement of the moving block 25. When the connecting line needs to be removed, the connecting cap 23 is loosened so that the insertion rod 211 no longer conflicts with the inclined surface of the moving block 25, and the tightened spring 1 29 will pull back the moving block 25 and reset it.
[0028] When the switch paddle 4 is not pulled down, the initial position of the clamping head 37 is on the left side of the square rod 33. At this time, directly pulling the switch paddle 4 downward will cause the square rod 33 to contact the inner side of the clamping head 37, so that the switch paddle 4 cannot be pulled down, preventing the staff from accidentally touching the production line equipment and causing it to stop working when it is not necessary to stop immediately. However, when it is necessary to stop immediately, the switch paddle 4 is pushed upward for a distance so that the connecting block 31 drives the square rod 33 to contact the reset block 38, but the spring 39 will push the reset block 38 tightly. When the switch paddle 4 is pulled downward, the square rod 33 pulls the reset block 38 to embed into the right side of the clamping head 37. When the switch paddle 4 is continued to be pulled, the square rod 33 no longer conflicts with the inner side of the clamping head 37, but conflicts with the inclined surface of the reset block 38, causing the square rod 33 to shrink into the circular hole 32, so that the clamping head 37 no longer conflicts with the square rod 33 under the engagement of the reset block 38, so that the switch paddle 4 can be pulled down to stop the device.
[0029] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
