DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example

[0025] like Figure 1-5As shown, an electric contact switch for low-voltage electrical appliances proposed in one embodiment of the utility model can adjust the rebound force of the switch for use. In different use occasions of the low-voltage electrical appliances, the rebound force of the switch can be adjusted. When the operator wears gloves, the pressing state of the electric contact switch can be sensed cleanly. The utility model comprises a switch housing 1 and a bottom seal 2. The bottom of the switch housing 1 is connected to the bottom seal 2, and a rebound member 3 is slidably inserted on the bottom seal 2. The top of the switch housing 1 is connected to a top seal 4, and a pressing button 5 is slidably connected in the top seal 4. The pressing button 5 is arranged to be in conflict with the conductive block 6. The conductive block 6 is slidably connected in the switch housing 1. The conductive block 6 is arranged to be in conflict with the connecting member 7. The connecting member 7 is connected to the bottom seal 2, the connecting piece 7 is slidably connected in the switch housing 1, the connecting piece 7 is in contact with the rebound piece 3, and a force adjusting piece 8 is rotatably connected on the bottom seal 2. The force adjusting piece 8 is threadedly connected to the rebound piece 3 and is welded with the connecting wire of the low-voltage electrical appliance through two terminal blocks 201. When operating the low-voltage electrical switch, the push button 5 is pressed, and the downward pressure of the push button 5 acts on the conduction block 6, and the downward pressure of the conduction block 6 acts on the connecting piece 7. Since the limiting column 702 is arranged between the two locking pieces 101, and the first inclined groove 102 and the second inclined groove 103 arranged on the locking piece 101 are staggered and relatively arranged, when the connecting piece 7 is pressed down, it will rotate, and the limiting column 702 will contact the locking piece below. When the push button 5 is released, the spring 302 rebounds, and the limiting column 702 is at the bottom of the first inclined groove 102 or the second inclined groove 103 provided on the lower locking member 101. The limiting column 702 is aligned with the inclined surface of the first inclined groove 102 or the second inclined groove 103 provided on the upper locking member 101. The spring 302 rebounds, causing the connecting member 7 to rise, and the limiting column 702 is engaged with the first inclined groove 102 or the second inclined groove 103 on the upper locking member 101. The groove depths of the first inclined groove 102 and the second inclined groove 103 are different, and the second inclined groove 103 is The groove 103 is deeper than the first inclined groove 102. Therefore, when the limiting column 702 is in the first inclined groove 102 on the upper locking member 101, the copper ring 703 will abut against the two contact pieces 203, so that the two contact pieces 203 can be connected. The arc surface design of the contact pieces 203 can improve the connection effect of the switch contacts and ensure the contact stability. When the push button 5 is pressed again, the connecting piece 7 will be pressed down and rotated. After the connecting piece 7 rebounds under the force of the rebound piece 3, the limiting column 702 is in the second inclined groove 103 on the upper locking member 101. At this time, the connecting piece 7 is in an ascending state inside the switch housing 1, and the copper ring 703 is disconnected from the contact piece 203, thereby improving the use effect.The locking member 101, the first inclined groove 102, the second inclined groove 103 and the limiting column 702 form a pressing and rotating mechanism, and its principle is the same as that of the pressing and rotating mechanism of a ballpoint pen, which will not be described in detail here. When it is necessary to adjust the rebound force of the pressing button 5, the slot 806 is plugged into the slot 806 by a slotted flat-head screwdriver to rotate and adjust the rotating disk 805. At this time, the plug-in column 804 will drive the rotating column 801 to rotate. Since the threaded section 802 is threadedly connected to the chassis 301, and the chassis 301 is slidably plugged into the two columns 204, when the rotating column 801 rotates, the lifting and lowering adjustment of the chassis 301 can be controlled. Since the top of the top plate 303 is in contact with the bottom plate 303, the bottom plate 301 is lifted and lowered. Inside the insulating cover 701, the distance between the top plate 303 and the bottom plate 301 is reduced, so that the spring 302 will be squeezed and contracted, and the pressing force on the push button 5 will be increased, and the push button 5 will rebound under the rebound force of the spring 302, so that when the operator wearing gloves operates the electric contact switch, the pressing perception can be improved to meet the use in different use environments. The plug-in column 804 is plugged into the plug-in hole 803, and the rotating disk 805 is rotatably connected to the rotating hole 501. Because when the push button 5 is pressed, the plug-in column 804 will be plugged and adjusted inside the plug-in hole 803, which will not affect the normal pressing and use of the push button 5.

[0026] An electric contact switch for low-voltage electrical appliances proposed in an embodiment of the utility model can achieve the effect of preventing accidental touch of the electric contact switch through a coordinated design. An L-shaped groove 401 is provided on the inner wall of the top seal 4, and a first protrusion 9 is fixedly connected to the outer wall of the push button 5. The first protrusion 9 is slidably connected in the L-shaped groove 401, and the push button 5 is fixedly connected to the outer ring end of the coil spring 10, and the inner ring end of the coil spring 10 is fixedly connected to the conductive block 6. The outer wall of the conductive block 6 is fixedly connected to the second protrusion 11, and the second protrusion 11 is slidably connected to the sliding groove 104. The sliding groove 104 is provided on the upper locking member 101. When the push button 5 is pressed, a rotational force needs to be applied to the push button 5 so that the first protrusion 9 is located at the bending part of the L-shaped groove 401, and then the push button 5 can be pressed down inside the top seal 4. When the push button 5 is rotated, the coil spring 10 will contract and maintain rebound. The force is applied. Since the conduction block 6 is slidably connected in the sliding groove 104 through the second protrusion 11, and the locking member 101 is fixedly connected to the inner wall of the switch housing 1, when the push button 5 is rotated, the conduction block 6 remains relatively still. When the push button 5 is rotated and pressed down, the rotating disk 805 is rotatably connected in the rotating hole 501, and the rotating disk 805 does not rotate and adjust with the push button 5. When the push button 5 rebounds, since the first protrusion 9 is connected to the vertical part of the L-shaped groove 401, there is no need to rotate and press. When the first protrusion 9 is in the horizontal part of the L-shaped groove 401, the coil spring 10 rebounds, so that the first protrusion 9 contacts the horizontal end of the L-shaped groove 401, and automatically resets to achieve the protection effect of preventing accidental touch. The design can avoid the accidental touch pressing operation of the push button 5, and improve the anti-accidental touch use effect of the electric contact switch.
