[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1, referring to Figure 1-3 This is the first embodiment of the present invention, which provides a positioning mechanism, including:

[0030] The receiving component 100 includes a housing 101 with an opening on one side;

[0031] The locking assembly 200 includes a through hole 201 disposed on the box body 101, a top block 202 disposed on the side wall of the through hole 201, the top block 202 being slidably disposed on the box body 101, and a pressing plate 203 disposed on the side of the top block 202 away from the limiting plate 204, the pressing plate 203 being elliptical in shape and being rotatably disposed on the box body 101.

[0032] The housing 101 is completely covered outside the switch. At the same time, the switch's switching knob 401 extends into the through hole 201. Rotating the pressing plate 203 causes the long axis side of the pressing plate 203 to press against the top block 202. The top block 202 moves toward the switching knob 401, pressing the switching knob 401 tightly. When it is necessary to adjust the switching knob 401, rotate the pressing plate 203 to release the pressure on the top block 202. At this time, the switching knob 401 can be rotated. That is, to operate the switching knob 401, the pressing plate 203 must be rotated first to release the positioning before the switching knob 401 can be rotated, thereby achieving the purpose of preventing accidental operation.

[0033] The through hole 201 is a round hole, and its size is sufficient for the normal rotation of the switching knob 401.

[0034] The housing 101 is completely covered outside the switch, protecting the switch and reducing the entry of dust, thereby reducing the problem of poor contact caused by dust accumulation. The upper part of the housing 101 is provided with a locking component 200 to lock and position the switching knob 401, so that the operation of the switching knob 401 requires the locking to be released first, thereby preventing accidental operation.

[0035] Furthermore, the locking assembly 200 also includes a limiting plate 204 rotatably disposed within the through hole 201, and the limiting plate 204 is provided with a limiting hole 205.

[0036] Because some switching knobs 401 have long, strip-shaped handles, a relatively large through-hole 201 is required to allow the knobs 401 to rotate. This undoubtedly increases the likelihood of dust entering the housing 101. By setting a limiting plate 204 to accommodate this type of switching knob 401, the problem of the large through-hole 201 is solved. Specifically, the through-hole 201 is a round hole, and the limiting plate 204 is a round plate that fits and is rotatably installed within the through-hole 201. The limiting plate 204 has a fitting... After the housing 101 covers the switch, the switch knob extends into the limiting hole 205. The long handle of the switch knob and the limiting hole 205 form a limit. Now the switch knob rotates in the limiting hole 205. At the same time, the top block 202 presses against the limiting plate 204, restricting the rotation of the limiting plate 204. When it is necessary to adjust the switch knob, rotate the pressing plate 203 to release the pressing of the top block 202 against the limiting plate 204. Then, the limiting plate 204 and the switch knob can be rotated as a whole.

[0037] Furthermore, the locking assembly 200 also includes a short rod 206 disposed at the center of the extrusion plate 203, and a swivel cap 207 is disposed at the end of the short rod 206 away from the extrusion plate 203.

[0038] The box body 101 is provided with a groove, and the extrusion plate 203 is rotatably disposed in the groove. The upper end of the extrusion plate 203 is connected to the rotating cap 207 through the short rod 206. By rotating the rotating cap 207, the extrusion plate 203 can be rotated to extrude the top block 202 or release the extrusion on the top block 202.

[0039] Furthermore, the top block 202 is a rubber or plastic part.

[0040] The top block 202 is made of a rubber or plastic part with a certain degree of elasticity. When the knob or the limiting plate 204 is squeezed, the contact is better and the squeezing force is higher, ensuring the positioning and locking effect.

[0041] Example 2, refer to Figure 1-6 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a power switching switch, including an upper positioning mechanism, and further comprising...

[0042] Mounting component 300, which includes mounting base 301;

[0043] The switching component 400 includes a switching knob 401 fixed on the mounting base 301, and terminal blocks 402 are provided on both sides of the switching knob 401. The terminal blocks 402 are fixed on the mounting base 301 and have wiring holes 403.

[0044] The housing 101 covers the outside of the mounting assembly 300 and the switching assembly 400.

[0045] Furthermore, the box body 101 has rolled edges 102 integrally extended on both sides of the opening end, and the rolled edges 102 are detachably connected to the mounting base 301.

[0046] When using the power switch, first install the mounting base 301 in the position of use, then cover the entire housing 101 outside the mounting component 300 and the switching component 400. The switching knob 401 extends from the through hole 201 or the limit hole 205 to protect the entire power switch and lock the switching knob 401 to prevent dust from entering and reduce the chance of misoperation.

[0047] The rolled edge 102 is specifically connected to the mounting base 301 in a detachable manner via bolts.

[0048] Example 3, referring to Figure 1-6This is the third embodiment of the present invention. Unlike the previous embodiment, the upper power switch also includes a clamping component 500 disposed outside the housing 101. The clamping component 500 includes a clamping plate 501, and the clamping plate 501 is provided with a clamping hole 502.

[0049] After the power switch is connected to the wire, the wire is clamped through the clamping hole 502 on the clamping plate 501 to prevent the wire connection from coming loose due to external force.

[0050] Furthermore, the position of the clamping hole 502 corresponds to the position of the wiring hole 403, and the inner wall of the clamping hole 502 is provided with a spring pad 503.

[0051] A spring pad 503 is provided on the inner wall of the clamping hole 502 to ensure the clamping effect while preventing the wire from being damaged.

[0052] Furthermore, the clamping plate 501 includes an upper plate 501a and a lower plate 501b disposed opposite to each other. The upper plate 501a and the lower plate 501b divide the clamping hole 502 into two parts, and the upper plate 501a and the lower plate 501b are detachably connected.

[0053] Furthermore, a card holder 504 is provided on the upper plate 501a, and a card block 505 is provided on the lower plate 501b, with the card holder 504 and the card block 505 engaging.

[0054] The clamping plate 501 adopts a combination structure of upper plate 501a and lower plate 501b, which facilitates the insertion of wires into the clamping holes 502. Specifically, both upper plate 501a and lower plate 501b are slidably mounted on the box 101. When wiring the power switch, upper plate 501a and lower plate 501b are in a separated state to ensure that the wire can be inserted normally. After wiring, slide upper plate 501a or lower plate 501b to the position of the wire so that the wire is in half of the clamping hole 502 of the plate. Then slide the other plate so that upper plate 501a and lower plate 501b are engaged together by the locking block 505 and the locking seat 504 to clamp the wire in the clamping hole 502. Of course, the box is provided with a wire hole for the power supply wire to pass through, and the size of the wire hole is sufficient to ensure that the wire and connector can pass through smoothly.
