Description

Technical Field

[0001] The utility model relates to the technical field of rotary switches, in particular to a rotary gear switch. Background Art

[0002] The rotary gear switch is a common electronic component, which is widely used in various devices and scenarios to achieve different function selection and control. These switches are widely used in many fields such as automobiles, home appliances, industrial equipment, etc.

[0003] However, the existing rotary gear switch usually only has a single contact piece. When in use, the switch is rotated, and the conductive contact piece contacts the switch contact piece to turn on the power. When turned off, the switch is rotated in the opposite direction, and the switch contact piece separates from the conductive contact piece to turn off the power. However, since the rotary switch needs to be rotated frequently, it is easy for the internal part to loosen, resulting in poor contact, affecting normal use and increasing unnecessary repair and maintenance costs.

[0004] Therefore, we designed a rotary gear switch to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a rotary gear switch to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model provides a rotary gear switch, comprising a base and a panel arranged on the front side of the base, including:

[0007] There are three groups of fixed shafts, each group has two fixed shafts, and the two fixed shafts are fixedly plugged into a corner of the base, and the fixed shafts are sleeved with conductive springs;

[0008] A rotating shaft is rotatably inserted in the panel, and one side is located outside the panel;

[0009] The gear is fixedly sleeved on the rotating shaft and is located between the base and the panel, and the teeth cooperate with the conductive spring sheet to abut against each other. A conductive sheet is also fixedly installed on one side of the gear, and the diameter of the conductive sheet is slightly smaller than the gear. The conductive sheet cooperates with the conductive spring sheet to abut against each other.

[0010] The rotary switch body is arranged at the front side of the rotary shaft and is used for driving the rotary shaft to rotate.

[0011] Furthermore, a placement opening is provided in the panel, and the rotating shaft is rotatably inserted in the placement opening.

[0012] Furthermore, the rotary switch body comprises a fixing seat, the fixing seat is fixedly mounted on the front side of the rotating shaft, and a fixing button is arranged on the front side of the fixing seat.

[0013] Furthermore, a fixing groove is provided on the front side of the fixing button, and an outer surface of the fixing groove is provided with anti-slip patterns.

[0014] Furthermore, a positioning block is fixedly installed on one side of the fixing button, a slot is provided on one side of the fixing seat, the other end of the positioning block is slidably inserted in the slot, a positioning slot is provided on the top of the positioning block, a bolt is threadedly inserted on the top of the fixing seat, and the end of the bolt is slidably inserted in the positioning slot.

[0015] Furthermore, a plurality of elastic pads are arranged in the base, and the material of the plurality of elastic pads is rubber.

[0016] Furthermore, a wiring port is provided in the base for convenient insertion of wires.

[0017] Compared with the prior art, the beneficial effect of the utility model is that by rotating the fixing button, the fixing seat, the gear and the conductive sheet can be driven to rotate. When the teeth on the gear abut against the conductive spring sheet, the conductive sheet and the conductive spring sheet do not contact each other, so no electricity is supplied. When the teeth on the gear are separated from the conductive spring sheet, the conductive spring sheet rebounds due to its own elastic force and abuts against the conductive sheet, and electricity can be supplied at this time. In addition, by arranging multiple conductive spring sheets, any conductive spring sheet abutting against the conductive sheet can achieve the effect of power supply, which effectively reduces the problem of poor contact and thus extends the service life of the rotary switch.

[0018] Compared with the prior art, the beneficial effect of the utility model is that when the fixing button is partially broken due to the rotation of external force, the bolt is rotated to screw the bolt out of the positioning groove, and then the fixing button is pulled, the broken fixing button can drive the positioning block to slide out of the slot, and then the new fixing button is connected to the fixing seat according to the above principle, so that the fixing button can be easily replaced, and the problem of the fixing button needing to be replaced as a whole when it is damaged is avoided.

DETAILED DESCRIPTION

[0025] 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.

[0026] See also Figure 1-5 The utility model provides a technical solution: a rotary gear switch, comprising a base 1 and a panel 2 arranged on the front side of the base 1, including:

[0027] There are three sets of fixed shafts 3, each set of fixed shafts 3 has two fixed shafts 3, two fixed shafts 3 are fixedly plugged into a corner of the base 1, and conductive springs 4 are sleeved on the fixed shafts 3;

[0028] The rotating shaft 5 is rotatably inserted in the panel 2, and one side of the rotating shaft 5 is located outside the panel 2;

[0029] The gear 6 is fixedly sleeved on the rotating shaft 5 and is located between the base 1 and the panel 2, and the teeth thereof cooperate with the conductive spring sheet 4 to abut against each other. A conductive sheet 7 is also fixedly mounted on one side of the gear 6. The diameter of the conductive sheet 7 is slightly smaller than that of the gear 6, and the conductive sheet 7 cooperates with the conductive spring sheet 4 to abut against each other.

[0030] The rotary switch body 8 is arranged at the front side of the rotary shaft 5 and is used to drive the rotary shaft 5 to rotate. A placement opening is opened in the panel 2, and the rotary shaft 5 is rotatably inserted in the placement opening.

[0031] In a specific implementation, by rotating the rotary switch body 8, the rotating shaft 5, the gear 6 and the conductive sheet 7 can be driven to rotate. When the teeth on the gear 6 abut against the conductive spring sheet 4, the conductive sheet 7 and the conductive spring sheet 4 do not contact each other, so no electricity is supplied. When the teeth on the gear 6 are disengaged from the conductive spring sheet 4, the conductive spring sheet 4 rebounds due to its own elastic force and abuts against the conductive sheet 7, and electricity can be supplied at this time. In addition, by providing a plurality of conductive spring sheets 4, any conductive spring sheet 4 abuts against the conductive sheet 7 to achieve the effect of power supply, which effectively reduces the problem of poor contact, thereby extending the service life of the rotary switch.

[0032] See also Figure 1-5The rotary switch body 8 includes a fixing seat 9, which is fixedly mounted on the front side of the rotating shaft 5. A fixing button 10 is provided on the front side of the fixing seat 9. When the rotating shaft 5 is rotated by a person, a force can be applied better.

[0033] See also Figure 1-5 A fixing groove 11 is provided on the front side of the fixing button 10, and an anti-skid pattern is provided on the outer surface of the fixing groove 11. The friction between the person and the fixing button 10 can be increased, thereby helping to solve the problem of slipping when the person turns the fixing button 10.

[0034] See also Figure 1-5 A positioning block 12 is fixedly installed on one side of the fixing button 10, a slot 13 is opened on one side of the fixing seat 9, the other end of the positioning block 12 is slidably inserted in the slot 13, a positioning slot 15 is opened on the top of the positioning block 12, a bolt 14 is threadedly inserted on the top of the fixing seat 9, and the end of the bolt 14 is slidably inserted in the positioning slot 15.

[0035] In specific implementation, based on the above implementation, when the fixing button 10 is partially broken due to the rotation of external force, the bolt 14 is rotated to screw the bolt 14 out of the positioning groove 15, and then the fixing button 10 is pulled, the broken fixing button 10 can drive the positioning block 12 to slide out of the slot 13, and then the new fixing button 10 is connected to the fixing seat 9 according to the above principle, so that the problem of facilitating the replacement of the fixing button 10 can be solved, and the problem of the fixing button 10 needing to be replaced as a whole when it is damaged can be avoided.

[0036] See also Figure 1-5 A plurality of elastic pads 16 are arranged in the base 1, and the material of the plurality of elastic pads 16 is rubber. Since the elastic pads 16 have a certain elasticity, they can achieve a shock-absorbing effect for the conductive sheet 7.

[0037] A wiring port 17 is provided in the base 1 for convenient insertion of wiring.

[0038] It should be noted that for the bolt 14, we can use a hand screw. An integrally formed button is provided on the side of the hand screw away from the end. A person can drive the bolt 14 to rotate as a whole by turning the button, so that the person can save more effort when turning the bolt 14. Since the hand screw is a prior art and is not a problem that needs to be solved by the background technology in this specification, it will not be explained in detail in this specification.

[0039] Working principle: When in use, by rotating the fixing button 10, the fixing seat 9, the gear 6 and the conductive sheet 7 can be driven to rotate. When the teeth on the gear 6 abut against the conductive spring sheet 4, the conductive sheet 7 and the conductive spring sheet 4 do not contact each other, so no electricity is supplied. When the teeth on the gear 6 are separated from the conductive spring sheet 4, the conductive spring sheet 4 rebounds due to its own elastic force and abuts against the conductive sheet 7, and electricity can be supplied at this time. In addition, by providing multiple conductive spring sheets 4, any conductive spring sheet 4 abuts against the conductive sheet 7 to achieve the effect of power supply, which effectively reduces the problem of poor contact, thereby extending the service life of the rotary switch;

[0040] In addition, when the fixing button 10 is partially broken due to the rotation of external force, the bolt 14 is rotated to screw the bolt 14 out of the positioning groove 15, and then the fixing button 10 is pulled. The broken fixing button 10 can drive the positioning block 12 to slide out of the slot 13, and then the new fixing button 10 is connected to the fixing seat 9 according to the above principle, so that the fixing button 10 can be easily replaced, and the problem of the fixing button 10 needing to be replaced as a whole when it is damaged can be avoided.
