Description

Technical Field

[0001] This utility model relates to the technical field of switch positioning mechanisms, specifically to a switch positioning mechanism and a switch. Background Technology

[0002] A switch is a device that can be turned on, off, or switched between positions by rotation or pressing. It is used to control the opening and closing of circuits or to switch current paths, and is widely used in various electrical appliances and industrial control fields. In order to keep the switch at a preset angle after rotation so as to maintain the electrical connection or disconnection between circuits, a switch positioning mechanism is usually provided on the switch.

[0003] Figure 12 This is a schematic diagram of the structure of a switch positioning mechanism in the prior art.

[0004] like Figure 12 As shown, the existing switch positioning mechanism 300 typically consists of a limiting shaft or ball bearing 8 and a mating component 7 with a groove 701 corresponding to the limiting shaft or ball bearing 8. When the control shaft inside the switch rotates, causing the mating component 7 to rotate to a preset position, the limiting shaft or ball bearing 8 can abut against the groove 701 of the mating component 7, fixing the position of the mating component 7. However, at this time, the mating component 7 still has a certain degree of free swing and cannot be completely fixed. With just a slight external force, the mating component 7 will be pushed to a certain extent, which can easily cause a partial break in the circuit and poor stability when the circuit is connected. Therefore, the versatility of this switch positioning mechanism 300 is also low, and it can only be applied to scenarios where the sensitivity requirements of the electrical connection of the circuit are not high.

[0038] Figure 2 This is a schematic diagram of the switch in an embodiment of this utility model.

[0039] like Figure 1-2 As shown, this embodiment provides a switch 200 for controlling the operating status of a device, including a switch positioning mechanism 100, a switch body 4, a control shaft, a control button 5, and two connecting rods 6.

[0040] The control button 5 is located at one end of the switch body 4 and is used to drive the control shaft to move or / and rotate.

[0047] Figure 3 This is a perspective view of the switch positioning mechanism in an embodiment of this utility model.

[0048] Figure 4 This is a schematic diagram of the switch positioning mechanism in an embodiment of this utility model.

[0049] like Figure 3-4 As shown, the switch positioning mechanism 100 in this embodiment includes a positioning body 1, which is composed of a base 102 and a cover plate 101.

[0050] Figure 5 This is a schematic diagram of the structure of some components of the base in an embodiment of this utility model.

[0051] like Figure 2-5 As shown, the upper and lower sides of the cover plate 101 (based on Figure 2 The base 102 has a connection hole 3a on its upper and lower sides (based on the viewing angle). Figure 2 (View angle), with a connecting hole 3b. A square through-hole 2a is provided in the middle of the cover plate 101, and a square through-hole 2c is provided in the middle of the base 102.

[0052] Specifically, in this embodiment, when assembling the switch 200, the cover plate 101 faces the first switch part 401, and the base 102 faces the second switch part 402. The cover plate 101 has first protrusions 105 at both ends of its middle portion near the first switch part 401.

The second switch part 402 has four second protrusions 4021 on its side near the base 102, their positions corresponding to the first protrusions 105, for engaging with the corresponding grooves on the base 102.

[0053] Figure 6 This is a schematic diagram of the base structure in an embodiment of this utility model.

[0054] Figure 7 This is a schematic diagram of the ratchet rotating in an embodiment of this utility model.

[0055] like Figure 4-7 As shown, the base 102 has a receiving portion 1021 inside, which is the horizontal section of the middle of the H-shape of the base 102. The receiving portion 1021 is provided with a ratchet 103 and a plurality of positioning components 104.

[0056] The ratchet 103, made of polyoxymethylene, is located in the middle of the receiving portion 1021. Two clearance grooves 1022 are provided on the sidewall of the receiving portion 1021 near the two connecting holes 3b, corresponding to the position of the ratchet 103. The maximum distance between the two clearance grooves 1022 is greater than the distance between the farthest two endpoints of the ratchet 103, allowing the ratchet 103 to rotate.

[0057] Figure 8 This is a perspective view of the ratchet in an embodiment of this utility model.

[0058] Figure 9This is a top view of the ratchet in an embodiment of this utility model.

[0059] like Figure 8-9 As shown, a square through-hole 2b is provided in the center of the ratchet 103. The ratchet 103 is a regular polygon, and each side of the ratchet 103 is an inwardly concave arc. Specifically, the ratchet 103 in this embodiment is a square, which corresponds to four rotation angle switching and fixing. That is, the device equipped with the switch 200 of this embodiment can perform four state switching. If more state switching is required, the ratchet 103 can be set as a regular polygon with more sides.

[0060] Two positioning components 104 are provided, located on both sides of the ratchet 103 and arranged opposite each other, for positioning the rotation angle of the ratchet 103, including a slider 1041 and two elastic elements, the elastic elements being springs 1043.

[0061] Figure 10 This is a perspective view of the slider in an embodiment of this utility model.

[0062] Figure 11 This is a schematic diagram of the slider in an embodiment of this utility model.

[0063] like Figure 6-7 As shown in 10-11, the slider 1041 abuts against both sides of the same side of the ratchet 103 to limit the position of the ratchet 103, including a first slider part 10411 and a second slider part 10422.

[0064] Limiting members 1042 are provided on both sides of the first slider portion 10411 to guide the slider 1041 to move along the extension direction of the limiting member 1042 and to limit the position of the slider 1041 after reset. A clearance slope is provided on the side of the limiting member 1042 near the ratchet 103. Receiving grooves 1044 are provided on both sides of the first slider portion 10411.

[0065] The second slider part 10422 is a steel sheet. Both sides of the second slider part 10422 abut against one edge of the ratchet 103. The second slider part 10422 is detachably connected to the first slider part 10411, which is convenient to replace according to the size of the ratchet 103, so that the ratchet 103 can be stably fixed in a preset position.

[0066] Two springs 1043 are disposed in two receiving grooves 1044, one end of which is fixedly connected to the side wall of the receiving part 1021, and the other end is fixedly connected to the first slider part 10411. When the ratchet 103 rotates, it pushes the slider 1041 to move away from the ratchet 103, and the spring 1043 is compressed and contracted. When the ratchet 103 rotates to the preset position, the spring 1043 extends and drives the slider 1041 to return to its original position.

[0067] Working principle: When it is necessary to switch the operating state of the equipment, rotating control knob 5 drives the control shaft and ratchet 103 to rotate together. When ratchet 103 rotates, it pushes slider 1041 to move away from ratchet 103, and spring 1043 is compressed and contracted. When the ratchet rotates 90°, spring 1043 extends, driving slider 1041 to return to its original position and abut against ratchet 103, fixing ratchet 103. Continuing to rotate control knob 5, the rotation process is the same as described above. When ratchet 103 rotates 90°, spring 1043 and slider 1041 are compressed and reset once, positioning ratchet 103 and switching the operating state of the equipment.

[0068] Functions and effects of the embodiments

[0069] The switch positioning mechanism 100 and switch 200 involved in this embodiment have the following beneficial effects:

[0070] The positioning body 1 has a receiving portion 1021 inside, which houses a ratchet 103 and multiple positioning components 104. Each positioning component 104 includes a slider 1041. The slider 1041 abuts against both sides of the same side of the ratchet 103 to limit the position of the ratchet 103. By simultaneously positioning the ratchet 103 from multiple positions, the contact area during abutment is increased, enhancing positioning stability. This avoids the problem of the ratchet 103 wobbling under slight external force after being fixed, ensuring stability during circuit connection. This allows the switch positioning mechanism 100 to be applied to scenarios with high sensitivity requirements for electrical connections, improving its versatility.

[0071] The ratchet 103 is a regular polygon, which makes it easy to position the rotation angle of the ratchet 103. Each side of the ratchet 103 is an inwardly concave arc, which makes it easy for the ratchet 103 to rotate.

[0072] Two positioning components 104 are provided, located on both sides of the ratchet 103 and arranged opposite to each other. By positioning the ratchet 103 from both sides simultaneously, the stability during positioning is increased, ensuring that the ratchet 103 will not shake due to slight external force.

[0073] Limiting elements 1042 are provided on both sides of the slider 1041 to facilitate the movement of the slider 1041 along the extension direction of the limiting elements 1042 and to limit the position of the slider 1041 after reset.

[0074] The positioning assembly 104 also includes two springs 1043. Receiving grooves 1044 are provided on both sides of the slider 1041, and the two springs 1043 are respectively disposed in the two receiving grooves 1044, improving space utilization. Furthermore, when the ratchet 103 rotates and pushes the slider 1041, the two springs 1043 provide support force on both sides of the slider 1041, enabling the slider 1041 to move more stably.

[0075] The receiving part 1021 has two clearance grooves 1022 on its wall, corresponding to the position of the ratchet 103. The maximum distance between the two clearance grooves 1022 is greater than the distance between the farthest two ends of the ratchet 103, which facilitates the rotation of the ratchet 103.

[0076] A switch 200 includes a switch positioning mechanism 100 and a switch body 4. The switch body 4 includes a first switch portion 401 and a second switch portion 402. The switch positioning mechanism 100 is disposed between the first switch portion 401 and the second switch portion 402. The first switch portion 401, the switch positioning mechanism 100, and the second switch portion 402 are engaged with each other through a protrusion and groove structure, which facilitates positioning and installation.

[0077] The switch 200 also includes a connecting rod 6, which passes through the switch positioning mechanism 100, the first switch part 401 and the second switch part 402, and is used to connect the switch positioning mechanism 100, the first switch part 401 and the second switch part 402, so as to fix the three together and prevent the switch body 4 from shaking when the control shaft rotates, which would affect the electrical connection of the circuit.
