Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and embodiments, it being understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

Referring to fig. 1 and 2, the invention provides a conveniently adjustable button switch, which comprises a housing 1, connecting terminals 2 arranged at two ends of the housing 1, a mounting port 13 arranged on the housing 1, and a button 3 movably arranged in the mounting port 13; the connecting terminal 2 is connected with a lead in the circuit (the connection mode of the connecting terminal 2 and the lead is the same as that of the terminal and the lead in the existing button), so that the button switch is connected with the circuit.

A conducting strip 4 (shown in fig. 2) which is fixedly connected with the button 3 and moves up and down is arranged inside the shell 1, and the conducting strip 4 is a copper sheet with good conducting performance; the initial state of the conducting plate 4 is at the upper end position, when the button 3 is pressed by an external force, the conducting plate 4 is driven to enter the lower end position, the bottom end of the shell 1 is provided with a guide post 41 for guiding the conducting plate 4, the conducting plate 4 is provided with a guide hole 42 corresponding to the guide post 41, and the guide post 41 is externally provided with a support spring 43 for driving the conducting plate 4 to be in the upper end initial state when the button 3 is not subjected to the external force; the inner side wall of the shell 1 is rotatably provided with a rotary disc 5 which is driven by a rotary driving assembly to rotate, the rotary disc 5 is provided with a conductive contact 51, the conductive contact 51 on the same side is electrically communicated with the connecting terminal 2 through a connecting assembly, and an internal circuit of the button switch is conducted when the conductive contact 51 is contacted with the conductive sheet 4; wherein, the connecting assembly includes a conductive ring 11 (shown in fig. 2 or 9) disposed on the sidewall of the housing 1 and a plurality of contacts 12 (shown in fig. 3) disposed around the turntable 5, and the contacts 12 are metal contacts; the conductive ring 11 is electrically connected to the connection terminal 2 (electrically connected means connected by a wire), and the contact 12 is electrically connected to the conductive contact 51; when the turntable 5 rotates, the contact 12 is always in contact with the conductive ring 11, so that the conductive communication effect between the conductive contact 51 and the connection terminal 2 is not affected by the rotation effect of the turntable 5, and the conductive contact 51 and the connection terminal 2 are always conducted.

Referring to fig. 2, 3, 8 and 9, preferably, an annular groove 111 is formed in the conductive ring 11; a first housing chamber 14 (shown in fig. 8) for mounting the contact 12 is provided on an outer wall of the rotary disk 5, the contact 12 is movably mounted in the first housing chamber 14, and an ejector spring 15 for supporting the contact 12 is mounted in the first housing chamber 14 (since the contact 12 is in a movable state, the contact 12 is connected with the conductive contact 51 through a flexible wire, which is not shown in the connection diagram). On the one hand, the installation of the rotating disc 5 is facilitated by the above structure, when the installation is performed, the contact 12 is contracted in the first accommodating chamber 14 by pressing the contact 12, then the rotating disc 5 is loaded into the conductive ring 11 and the contact 12 is released, and the contact 12 will extend out of the first accommodating chamber 14 and be clamped into the groove 111 under the action of the ejection spring 15. On the other hand, the positioning of the rotary disc 5 is realized through the matching of the groove 111 and the contact 12, and the rotary disc 5 is prevented from falling out of the conductive ring 11 when rotating.

The rotating turntable 5 can drive the conductive contact 51 to switch between a top state and a bottom state. When the conductive contact 51 is in the top state (shown in fig. 11), the push button switch is in the normally closed mode (because the initial state of the conductive sheet 4 is in the upper end position, at which time the conductive sheet 4 is always in contact with the conductive contact 51), and when the conductive contact 51 is in the bottom state (shown in fig. 10), the push button switch is in the normally open mode (because the initial state of the conductive sheet 4 is in the upper end position, at which time the conductive sheet 4 is not in contact with the conductive contact 51). The initial state of the button switch in the normally closed mode is that the conductive contact 51 is at the top position and contacts with the conductive sheet 4, and the circuit is conducted; when the button 3 is pressed by external force, the conductive contact 51 is separated from the conductive sheet 4, and the circuit is broken; the initial state of the button switch in the normally open mode is that the conductive contact 51 is at the bottom position and is separated from the conductive sheet 4, and the circuit is broken; when the button 3 is pressed by an external force, the downward moving conductive sheet 4 contacts the conductive contact 51, and the circuit is conducted.

In this example, when the push switch is used, the rotary driving assembly is controlled to drive the rotary disc 5 to the required position (the conductive contact 51 is in the top end state and the bottom end state) according to the requirement (the normally closed mode or the normally open mode), and then the circuit in the circuit is connected with the connecting terminals 2 at the two ends.

When switching between the modes (switching between the normally closed mode and the normally open mode), it is only necessary to control the rotation driving assembly to drive the rotating disc 5 to rotate by a predetermined angle, so that the conductive contact 51 performs state switching.

Referring to fig. 2, fig. 3, fig. 5 and fig. 6, in order to prevent the conductive contact 51 from interfering with the conductive sheet 4 when the turntable 5 rotates, so that the turntable 5 cannot rotate, the apparatus is further optimized, wherein the conductive contact 51 is mounted on a moving member 61, and a second accommodating chamber for accommodating the moving member 61 is arranged on the turntable 5; when the turntable 5 rotates and is in the switching process of the top end state and the bottom end state (not reaching a preset angle), the moving member 61 is driven by a guide assembly to be retracted into the second accommodating bin; when the conductive contact 51 enters the top end state or the bottom end state, the moving member 61 extends out of the second accommodating chamber and enables the conductive contact 51 to be matched (contacted) with the conductive sheet 4; the guide assembly comprises a first semi-annular guide rail 62 (shown in fig. 9) arranged on the side wall of the housing 1 and a pull rod 63 (shown in fig. 5) arranged at the end of the moving member 61 and matched with the first guide rail 62; the inner wall of the first guide rail 62 is provided with a guide groove 64, the guide groove 64 comprises an outer slide channel 641 and an inner slide channel 642 (shown in fig. 6) which are communicated with each other, the end of the pull rod 63 is provided with a pull block 631, and the pull block 631 is arranged in the guide groove 64. The first guide rail 62 is configured as a semi-annular structure, so that the rotary table 5 can be rotationally positioned, and the rotary table 5 can only rotate within a predetermined angle range, and the two end positions of the rotary table 5 are the positions of the top end state and the bottom end state of the conductive contact 51; when the turntable 5 rotates, the pulling block 631 slides in the guiding groove 64, and when the pulling block 631 moves into the outer sliding channel 641, the pulling rod 63 ejects the moving element 61 out of the second accommodating chamber; when the pulling block 631 moves into the inner slide 642, the pulling rod 63 pulls the moving member 61 into the second compartment. When the turntable 5 rotates (during the mode switching process), the moving member 61 is retracted into the second accommodating chamber, so that the motion interference between the conductive contact 51 and the conductive sheet 4 can be avoided.

Referring to fig. 2 and 4, the rotation driving assembly includes a rotation adjusting sleeve 71 rotatably mounted at the mounting opening 13, a first gear ring 72 disposed at a lower end of the rotation adjusting sleeve 71, and a second gear ring 73 disposed at an outer edge of the rotary plate 5 and engaged with the first gear ring 72 (shown in fig. 2 or 3). When the rotation driving assembly is driven to work, only the rotation adjusting sleeve 71 needs to be rotated, and the rotating disc 5 can be driven to rotate through transmission between the gears, further explained, because the rotating directions of the two rotating discs 5 are different, the opening directions of the half rings of the first guide rail 62 are opposite.

Preferably, a positioning assembly for locking the position of the rotating disc 5 is arranged between the upper end of the rotating adjusting sleeve 71 and the shell 1; realize the rotation locking to carousel 5 through locating component, avoid after the mode switch finishes (when button switch is in operating condition), carousel 5 takes place angular deviation for conducting strip 4 takes place contact failure's phenomenon with conductive contact 51.

Referring to fig. 2 and 7, the positioning assembly includes a positioning ring 81 sleeved on the upper end of the rotation adjusting sleeve 71, a first positioning key 82 disposed on the inner wall of the lower end of the positioning ring 81, and a plurality of key slots (shown in fig. 9) disposed on the outer wall of the mounting opening 13 of the housing 1; the positioning ring 81 and the rotation adjusting sleeve 71 are rotatably positioned through a second positioning key 83 (the second positioning key 83 is a single key structure) arranged at the upper end of the positioning ring 81, the rotation of the positioning ring 81 further drives the rotation adjusting sleeve 71 to synchronously rotate under the action of the second positioning key 83, and a return spring 84 for driving the positioning ring 81 to reset is arranged between the positioning ring 81 and the rotation adjusting sleeve 71. When the rotation adjusting sleeve 71 needs to be driven to rotate, the positioning ring 81 needs to be lifted upwards (at this time, the return spring 84 contracts, and the second positioning key 83 slides in the key slot), so that the first positioning key 82 is separated from the key slot, and at this time, the positioning ring 81 is in a rotatable state, and the rotation adjusting sleeve 71 is driven to rotate by the rotation positioning ring 81 under the action of the second positioning key 83; after the rotating adjusting sleeve 71 is driven to rotate to the predetermined position, the holding ring 81 is removed, and the first positioning key 82 is driven by the positioning ring 81 to be clamped into the corresponding key slot under the action of the return spring 84.
