Description

Technical Field

[0001] The utility model belongs to the field of switch buttons, and in particular relates to a machine switch button safety emergency stop operation function device. Background Art

[0002] At present, when employees of the WBDInline machine handle abnormalities, violate regulations, have weak safety awareness, and extend their arms to the left and right inlet and outlet tracks of the ARM bracket, the machine will not stop operating in the event of a safety emergency. The ARM bracket will continue to collide and squeeze the front and rear ends, posing a great safety hazard. We have specially added a function that when a safety emergency occurs on the machine, you can press and hold the switch button on the machine for one second to achieve an emergency stop function.

[0003] At present, WBD equipment has no stop function when a safety emergency occurs, which poses a great safety hazard and brings unnecessary property losses to the company. In particular, when a safety emergency occurs on the machine, the emergency stop function can be achieved by pressing and holding the switch button on the machine for one second. However, the switch button on the current machine is easily accidentally touched by employees, causing the equipment to stop suddenly.

[0004] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0026] The utility model will now be described in further detail with reference to the accompanying drawings.

[0027] See also Figure 1-5 As shown, in this embodiment, a machine switch button safety emergency stop operation function device is provided, including a housing 1, a limit slot is provided on the top of the housing 1, a control knob is rotatably and slidably matched in the limit slot, a tilting ring 8 is provided at the bottom of the control knob, an extrusion slot 9 is provided at the bottom of the tilting ring 8, a mounting cavity 12 is provided in the housing 1, an emergency stop button 16 is provided in the mounting cavity 12, a trigger spring 17 is provided on the emergency stop button 16, a reset component is provided in the limit slot, and the reset component cooperates with the control knob;

[0028] A limit cavity 10 is provided in the housing 1 , and an extrusion piece is slidably and elastically matched in the limit cavity 10 . The extrusion piece is matched with the extrusion groove 9 , and the extrusion piece is matched with the trigger spring piece 17 .

[0029] The application of one aspect of this embodiment is: when in use, by rotating the control knob, the rotation of the control knob drives the tilting ring 8 to rotate, and the rotation of the tilting ring 8 causes the extrusion groove 9 to squeeze the extrusion piece, thereby causing the extrusion piece to move downward, and then the control knob is pressed to move the control knob downward, and the downward movement of the control knob drives the tilting ring 8 to move downward, and the downward movement of the tilting ring 8 drives the extrusion piece to move downward again, thereby causing the extrusion piece to squeeze the trigger spring piece 17, so that the emergency stop button 16 is activated, and the machine can be controlled to stop operation in time, and the loss caused by the collision can be prevented in time, and the machine can be effectively protected. After the machine stops, the control knob is released, and the control knob is reset under the action of the reset component. Moreover, by rotating and pressing the control knob, accidental pressing or accidental rotation of the control knob can be effectively prevented, which may cause the equipment to stop suddenly, thereby avoiding accidental touch by the staff.

[0030] See also Figure 1-3 As shown, the limit groove of this embodiment includes a mounting groove 5 opened on the top of the shell 1, a horizontal slide groove 6 is opened on the side of the mounting groove 5, a vertical slide groove 7 is opened on the side of the mounting groove 5, the horizontal slide groove 6 and the vertical slide groove 7 are connected, and the control knob cooperates with the mounting groove 5, the horizontal slide groove 6 and the vertical slide groove 7; a sealing strip is provided at the opening of the mounting groove 5 to prevent debris from entering the mounting groove 5.

[0031] See also Figure 1-4 As shown, the control knob of this embodiment includes a control button 2 that rotates and slides in the installation groove 5, a limit slider 4 is installed on the side of the control button 2, the limit slider 4 slides in the horizontal slide groove 6 and the vertical slide groove 7, a plurality of anti-slip strips 3 are installed on the side of the control button 2, and a tilting ring 8 is installed at the bottom of the control button 2.

[0032] By rotating the control button 2, the rotation of the control button 2 drives the tilting ring 8 to rotate, and the rotation of the tilting ring 8 causes the extrusion groove 9 to extrude the extrusion piece, thereby causing the extrusion piece to move downward. At the same time, the rotation of the control button 2 drives the limit slider 4 to slide in the horizontal slide groove 6 to above the vertical slide groove 7, so that the limit slider 4 can enter the vertical slide groove 7, thereby releasing the limit on the control button 2, and then pressing the control button 2 to move down. The downward movement of the control button 2 drives the tilting ring 8 to move down, and the downward movement of the tilting ring 8 drives the extrusion piece to move down again, thereby activating the emergency stop button 16. The limit slider 4 can avoid accidental pressing of the control button 2, which may cause the equipment to stop suddenly, thereby avoiding accidental touch by the staff.

[0033] See also Figure 1-3As shown, the reset assembly of this embodiment includes a reset block 18 that slides in the vertical slide groove 7, a reset spring 19 is installed between the reset block 18 and the vertical slide groove 7, a torsion spring is installed at the rotation point of the control button 2 and the mounting groove 5, and the reset block 18 cooperates with the limit slider 4; through the reset assembly, under the action of the reset spring 19, the reset block 18 squeezes the limit slider 4, so that the limit slider 4 returns to the horizontal slide groove 6, and then under the action of the torsion spring, the control button 2 and the limit slider 4 are reset.

[0034] See also Figure 1-5 As shown, the top and bottom of the limiting cavity 10 of this embodiment are both provided with through holes 11, and the extrusion member includes a touch rod 13 that is slidably fitted in the through hole 11, and a fixing block 14 is installed on the side of the touch rod 13. The fixing block 14 is slidably fitted in the limiting cavity 10, and a rebound spring 15 is installed between the fixing block 14 and the limiting cavity 10.

[0035] By means of the extrusion piece, when the control button 2 rotates and drives the extrusion groove 9 on the tilting ring 8 to squeeze the touch rod 13, the touch rod 13 moves down a certain distance. At this time, there is still a certain distance between the touch rod 13 and the trigger spring 17, so as to avoid the emergency stop of the equipment due to accidental rotation of the control button 2, thereby avoiding accidental touch by the staff. When the control button 2 moves down and drives the tilting ring 8 to move down, the tilting ring 8 moves down and drives the touch rod 13 to move down again, so that the touch rod 13 squeezes the trigger spring 17, so that the trigger spring 17 activates the emergency stop button 16, so as to timely control the emergency stop operation of the machine and timely prevent the loss caused by the collision.

[0036] See also Figure 1-4 As shown, the upper side of the inclined ring 8 of this embodiment is a plane, the lower side of the inclined ring 8 is an inclined surface, and the extrusion groove 9 is inclined; the inclined setting of the extrusion groove 9 can enable the extrusion groove 9 to control the touch rod 13 to move downward a certain distance.
