Description

Technical Field

[0001] This utility model relates to the field of electrical switch technology, and more specifically, to a columnar plastic button structure for electrical appliances. Background Technology

[0002] Electrical appliances typically have columnar plastic buttons for turning a function on and off. These buttons usually consist of a pressing mechanism, a reset mechanism, and an actuating mechanism. The actuating mechanism can be a conductive contact or a lever. However, existing columnar plastic buttons are usually designed to move vertically up and down, which may lead to accidental activation or deactivation by people or objects. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a columnar plastic button structure for electrical appliances, which has the advantage of avoiding accidental activation or deactivation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a columnar plastic button structure for electrical appliances, comprising a columnar tube, wherein a pressing shaft is movably connected to the top end of the columnar tube, and the pressing shaft has a degree of freedom of movement in the vertical direction; A support ring, wherein a trigger assembly is movably connected to the middle of the support ring, and a rotating plate is fixedly installed at the top of the trigger assembly, the rotating plate having a degree of freedom of rotational movement; A paddle and a guide groove, wherein the paddle is fixedly installed on the side wall of the rotating plate, and the guide groove is formed on the side wall of the columnar tube; A first movable block is fixedly installed at the bottom end of the pressing shaft, and a second movable block is fixedly installed at the top end of the rotating plate. The first movable block has a degree of freedom of movement in the vertical direction. The top end of the pressing shaft passes through and extends above the columnar tube, and the surface of the pressing shaft is provided with multiple square grooves.

[0005] The working principle and beneficial effects of the above technical solution are as follows: By setting the inside of the columnar tube to a pressing shaft and a rotating plate, when the pressing shaft is accidentally pressed, although the pressing shaft is pressed down, the plate does not rotate because it is stuck in the guide groove. Therefore, it will not press the rotating plate and the trigger component to move down as a whole, and the trigger component will not move down to press the actuator located at the bottom of the columnar tube, thus avoiding accidental pressing.

[0006] By creating multiple square grooves on the surface of the pressing shaft, the anti-slip effect of the pressing shaft can be increased, making it easier to rotate the pressing shaft.

[0007] As a preferred embodiment of this utility model, the guide groove is L-shaped, the paddle is movably connected inside the guide groove, and the length of the paddle is greater than the width of the guide groove.

[0008] The working principle and beneficial effects of the above technical solution are as follows: the direction of movement of the paddle is positioned by the guide groove, thereby controlling the rotation and up-down movement of the rotating piece. Furthermore, by setting the paddle to be longer than the width of the guide groove, the end of the paddle can be located on the outside of the columnar tube, making it easy to paddle.

[0009] As a preferred embodiment of the present invention, the first moving block is located above the second moving block, and the projection of the first moving block on the horizontal plane is offset from that of the second moving block.

[0010] The working principle and beneficial effects of the above technical solution are as follows: There are four of each of the first and second moving blocks, which can achieve uniform control of the rotation of the rotating plate. When the first moving block comes into contact with the second moving block, rotating the pressing shaft can drive the rotating plate to rotate.

[0011] As a preferred embodiment of this utility model, a first spring is fixedly installed at the top of the rotating plate, the top of the first spring is fixedly connected to the pressing shaft, and the first spring is located inside the first moving block and the second moving block.

[0012] The working principle and beneficial effects of the above technical solution are as follows: By setting a first spring, the elasticity generated by the compression of the first spring can drive the pressing shaft to move upward and reset when the pressing shaft loses pressure. Since the first spring connects the rotating plate and the pressing shaft, the pressing shaft will twist the first spring when it rotates relative to the rotating plate. The first spring will also generate elasticity in the horizontal direction. Therefore, when the pressing shaft is released, the elasticity in the horizontal direction of the first spring can be used to drive the pressing shaft to flip and reset.

[0013] As a preferred embodiment of this utility model, a second spring is fixedly installed at the top end of the support ring, the top end of the second spring is in contact with the rotating plate, and the second spring is sleeved on the outside of the trigger assembly.

[0014] The working principle and beneficial effects of the above technical solution are as follows: By setting a second spring, the elasticity generated by the compression of the second spring can drive the rotating plate to move upward and reset after the rotating plate is unlocked. At the same time, the rotating plate and the second spring are only in contact and not fixed, so that the second spring will not be twisted when the rotating plate rotates.

[0015] As a preferred embodiment of this utility model, a placement groove is provided on the rear side of the bottom end of the columnar tube, and multiple fixing holes are provided at the bottom end of the columnar tube. The triggering component includes a fixed shaft, an adjusting block, and a stud. The top end of the fixed shaft is fixedly connected to the rotating plate, the adjusting block is located below the fixed shaft, the bottom end of the stud is fixedly connected to the adjusting block, the stud is engaged in the fixed shaft, and a cross-shaped groove is provided at the bottom end of the adjusting block.

[0016] The working principle and beneficial effects of the above technical solution are as follows: A fixing hole is provided for fixing the cylindrical tube to the electrical appliance using screws. A placement slot is provided for placing the actuator, such as a conductive contact or rod, at the bottom of the cylindrical tube, i.e., on the electrical appliance. A screwdriver inserted into the cross-shaped slot allows rotation of the adjusting block, thereby adjusting the distance between the adjusting block and the fixing shaft. This allows the adjusting block to move up and down, adjusting the distance between the adjusting block and the actuator placed at the bottom of the cylindrical tube's inner cavity. Since the thickness of different actuators varies, this adjustable feature ensures stable contact with the actuator after the pressing shaft moves downwards, causing the trigger component to move downwards.

[0017] As a preferred embodiment of this utility model, a pull rod is slidably connected to the left end of the columnar tube, a locking block is fixedly installed at the right end of the pull rod, and a third spring is fixedly installed between the locking block and the columnar tube.

[0018] The working principle and beneficial effects of the above technical solution are as follows: When the rotating plate moves down, it can push the locking block into the columnar tube. When the rotating plate is below the locking block, the compressed third spring provides elasticity to push the locking block above the rotating plate, thereby locking the position of the rotating plate. Furthermore, after pulling the lever to allow the locking block to retract into the columnar tube, the rotating plate is unlocked and moves upward to reset under the elastic force of the second spring.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a columnar plastic button structure for electrical appliances, including a columnar tube 1, with a pressing shaft 2 movably connected to the top of the columnar tube 1, and the pressing shaft 2 having a degree of freedom of movement in the vertical direction; A support ring 6 is provided, and a trigger component 5 is movably connected to the middle of the support ring 6. A rotating plate 3 is fixedly installed at the top of the trigger component 5, and the rotating plate 3 has a degree of freedom of rotational movement. The paddle 4 and the guide groove 9 are fixedly installed on the side wall of the rotating plate 3, and the guide groove 9 is opened on the side wall of the columnar tube 1. The first moving block 7 is fixedly installed at the bottom end of the pressing shaft 2, and the second moving block 8 is fixedly installed at the top end of the rotating plate 3. The first moving block 7 has a degree of freedom of movement in the vertical direction.

[0023] The working principle and beneficial effects of the above technical solution are as follows: By setting the inside of the columnar tube 1 to a pressing shaft 2 and a rotating plate 3, when the pressing shaft 2 is accidentally pressed, although the pressing shaft 2 is pressed down, the paddle 4 is stuck in the guide groove 9 and does not rotate. Therefore, it will not press the rotating plate 3 and the trigger component 5 down as a whole, and the trigger component 5 will not be able to press down and press the actuator located at the bottom of the columnar tube 1, thereby avoiding accidental pressing.

[0024] The top end of the pressing shaft 2 extends through and above the columnar tube 1, and multiple square grooves are formed on the surface of the pressing shaft 2.

[0025] The working principle and beneficial effects of the above technical solution are as follows: By opening multiple square grooves on the surface of the pressing shaft 2, the anti-slip effect of the pressing shaft 2 can be increased, making it easier to rotate the pressing shaft 2.

[0026] The guide groove 9 is L-shaped, and the paddle 4 is movably connected inside the guide groove 9. The length of the paddle 4 is greater than the width of the guide groove 9.

[0027] The working principle and beneficial effects of the above technical solution are as follows: the movement direction of the paddle 4 is positioned by the guide groove 9, thereby controlling the rotation and up-down movement of the rotating piece 3. Furthermore, by setting the paddle 4 to be longer than the width of the guide groove 9, the end of the paddle 4 can be located outside the columnar tube 1, making it easy to paddle.

[0028] The first moving block 7 is located above the second moving block 8, and the projection of the first moving block 7 on the horizontal plane is offset from that of the second moving block 8.

[0029] The working principle and beneficial effects of the above technical solution are as follows: There are four of each of the first moving block 7 and the second moving block 8, which can achieve uniform control of the rotation of the rotating plate 3. When the first moving block 7 contacts the second moving block 8, rotating the pressing shaft 2 can drive the rotating plate 3 to rotate.

[0030] The rotating plate 3 has a first spring 10 fixedly installed at its top end. The top end of the first spring 10 is fixedly connected to the pressing shaft 2. The first spring 10 is located inside the first moving block 7 and the second moving block 8.

[0031] The working principle and beneficial effects of the above technical solution are as follows: By setting the first spring 10, the elasticity generated by the compression of the first spring 10 can drive the pressing shaft 2 to move upward and reset when the pressing shaft 2 loses its pressing force. Since the first spring 10 connects the rotating plate 3 and the pressing shaft 2, when the pressing shaft 2 rotates relative to the rotating plate 3, it will twist the first spring 10, and the first spring 10 will also generate elasticity in the horizontal direction. Therefore, when the pressing shaft 2 is released, the elasticity in the horizontal direction of the first spring 10 can be used to drive the pressing shaft 2 to flip and reset.

[0032] The support ring 6 has a second spring 11 fixedly installed at its top end. The top end of the second spring 11 contacts the rotating plate 3. The second spring 11 is sleeved on the outside of the trigger assembly 5.

[0033] The working principle and beneficial effects of the above technical solution are as follows: By setting the second spring 11, the elasticity generated by the compression of the second spring 11 can drive the rotating plate 3 to move upward and reset after the rotating plate 3 is unlocked. At the same time, the rotating plate 3 and the second spring 11 are only in contact and not fixed, so that the rotating plate 3 will not twist the second spring 11 when it rotates.

[0034] The columnar tube 1 has a placement groove 12 on the rear side of its bottom end and multiple fixing holes 13 at its bottom end. The trigger assembly 5 includes a fixed shaft 51, an adjusting block 52 and a stud 53. The top end of the fixed shaft 51 is fixedly connected to the rotating plate 3. The adjusting block 52 is located below the fixed shaft 51. The bottom end of the stud 53 is fixedly connected to the adjusting block 52 and the stud 53 is engaged in the fixed shaft 51. The bottom end of the adjusting block 52 has a cross-shaped groove.

[0035] The working principle and beneficial effects of the above technical solution are as follows: A fixing hole 13 is provided for fixing the columnar tube 1 to the electrical appliance with screws. A placement groove 12 is provided for placing the actuator, such as a conductive contact or rod, at the bottom end of the columnar tube 1, i.e., on the electrical appliance. By inserting a screwdriver into the cross-shaped groove, the adjusting block 52 can be rotated, thereby adjusting the distance between the adjusting block 52 and the fixing shaft 51, so that the adjusting block 52 can move up and down, adjusting the distance between the adjusting block 52 and the actuator placed at the bottom end of the inner cavity of the columnar tube 1. When facing different types of actuators, since the thickness of the actuators is not the same, this is made adjustable, which can ensure stable contact with the actuator after the pressing shaft 2 moves down and drives the trigger component 5 to move down.

[0036] The left end of the columnar tube 1 is slidably connected to a pull rod 14, the right end of the pull rod 14 is fixedly installed with a locking block 15, and a third spring 16 is fixedly installed between the locking block 15 and the columnar tube 1.

[0037] The working principle and beneficial effects of the above technical solution are as follows: When the rotating plate 3 moves down, it can push the locking block 15 into the columnar tube 1. When the rotating plate 3 is below the locking block 15, the compressed third spring 16 provides elasticity to push the locking block 15 above the rotating plate 3, thereby locking the position of the rotating plate 3. After the pull rod 14 is pulled to make the locking block 15 into the columnar tube 1, the rotating plate 3 is unlocked and moves up to reset under the elastic force of the second spring 11.

[0038] Working principle and usage process of this utility model: First, the actuator is installed on the electrical appliance. It is similar to a conductive contact that does not change position and is directly fixed to the electrical appliance. It is similar to a lever that needs to be pressed to move in order to open and is movably connected to the electrical appliance. Then, the adjusting block 52 is turned to adjust the total length of the fixed shaft 51 and the adjusting block 52 to ensure that the actuator can be triggered smoothly. Finally, the bottom end of the column tube 1 is covered with the actuator and the fixing hole 13 is fixed from the back of the electrical appliance with screws. In use, first press down on the pressing shaft 2. When the first moving block 7 and the second moving block 8 are in contact with each other, rotating the pressing shaft 2 can drive the rotating plate 3 and the paddle 4 to rotate through the first moving block 7 and the second moving block 8, so that the paddle 4 moves in the guide groove 9. When the paddle 4 is in the vertical area in the guide groove 9, press the pressing shaft 2 again, which can drive the rotating plate 3 to move down, thereby driving the trigger component 5 to move down and trigger the execution structure. At this time, the compressed third spring 16 provides elasticity to push the locking block 15 into the top of the rotating plate 3, thereby locking the position of the rotating plate 3 and turning on the electrical function. Then release the hand, and the first spring 10 in the compressed state will drive the pressing shaft 2 to move up and reset under the action of elasticity. When turning off the electrical function, first pull the lever 14 to disengage the locking block 15 from the rotating plate 3. At this time, the elasticity of the second spring 11 causes the rotating plate 3 to move upward. When the lever 4 is at the top of the guide groove 9, the lever 4 is reversed to drive the rotating plate 3 to reverse and reset the rotating plate 3. In addition, except for the first spring 10, the second spring 11 and the third spring 16, this product is made of plastic material.
