When the operating rod is rotated, the control structure can control the opening and closing of the circuit.

[0004] When workers are repairing a circuit breaker, they may accidentally touch the operating lever, causing the operating lever to connect the circuit through the control structure, causing the workers to be in a dangerous situation. Summary of the Invention

[0005] In order to improve the problem that workers may accidentally touch the operating lever during maintenance, the present application provides an anti-accidental-touch direct-acting circuit breaker.

[0006] The present application provides an anti-accidental-touch direct-acting circuit breaker, which adopts the following technical solution: A direct-acting circuit breaker with an anti-accidental contact function comprises a housing, an operating rod rotatably connected to the housing, a control structure provided on the housing, the operating rod rotatably connected to the control structure, a stop plate slidably connected to the housing, a stop block provided on the stop plate, and a stop groove provided on the operating rod for inserting the stop block; when the stop block is inserted into the stop groove, the operating rod is fixed to the housing.

[0007] By adopting the above technical solution, the stop block is inserted into the stop groove, so that the stop block limits the operating rod, so that the operating rod cannot rotate on the shell, so that the staff can slide the stop plate to fix the operating rod during maintenance, thereby preventing the staff from accidentally touching the operating rod.

[0008] Optionally, two waterproof strips are slidably connected to the shell, and waterproof sponges are provided on the waterproof strips. The waterproof strips are respectively located on both sides of the operating rod; when the two waterproof strips abut against each other, the waterproof sponges abut against the operating rod.

[0009] By adopting the above technical solution, two waterproof strips are respectively provided on both sides of the operating rod, so that the two waterproof strips can abut the operating rod, so that the moisture on the outer surface of the operating rod can be absorbed by the waterproof sponge, thereby preventing the moisture on the outer surface of the operating rod from spreading into the control structure, reducing the possibility of damage to the control structure due to excessive moisture.

[0010] Optionally, a first rack is provided on the stop plate, a second rack is provided on the waterproof strip, and a rotating gear is meshed and connected between the first rack and the second rack; when the stop block is inserted into the stop groove, the waterproof sponge does not abut the operating rod; when the waterproof sponge abuts the operating rod, the stop block disengages from the stop groove.

[0011] By adopting the above technical solution, when the staff slides the stop plate to disengage the stop block from the stop groove, the first rack drives the second rack to move by rotating the gear, so that the waterproof sponge can abut against the operating rod, and the waterproof sponge can absorb water from the outer surface of the operating rod, so that the staff does not need to move the waterproof strip again, reducing the staff's operating steps.

[0012] Optionally, a accommodating cavity is provided on the shell, and the waterproof strip and the stop plate are both slidably connected to the accommodating cavity. A through hole connected to the accommodating cavity is provided on the shell, and a movable strip is slidably connected in the through hole. A accommodating block for inserting into the through hole is provided on the waterproof sponge; when the accommodating block is located in the through hole, the waterproof sponge does not abut the operating rod, and at this time the movable strip protrudes from the shell.

[0013] By adopting the above technical solution, when the waterproof strip slides, the waterproof sponge can move to the perforation, allowing the accommodating block to move from the accommodating cavity to the perforation, and the accommodating block pushes the moving strip, allowing the moving strip to protrude from the classroom, so that the staff can directly observe the position of the moving strip, so that the staff can directly judge whether the waterproof sponge is abutting the operating rod, and avoid the staff forgetting to move the waterproof strip, causing moisture on the outside of the operating rod to enter the control structure.

[0014] Optionally, a movable groove connected to the perforation is provided on the shell, the movable groove is for the movable bar to slide, the waterproof sponge is slidably connected to the waterproof strip, and the waterproof sponge can be detached from the perforation; when the movable bar is located in the movable groove, the movable bar is not on the moving path of the waterproof sponge.

[0015] By adopting the above technical solution, since the waterproof sponge can be detached from the perforation, when the accommodating block is located in the perforation, the accommodating block can pre-fix the waterproof sponge. At this time, the staff moves the movable bar from the perforation to the movable groove, so that the movable bar is not in the moving path of the waterproof sponge detaching from the accommodating cavity, thereby allowing the staff to take the waterproof sponge out of the accommodating cavity, so that the staff can replace the waterproof sponge.

[0016] Optionally, a fixing block is provided on the waterproof sponge, a fixing hole for inserting the fixing block is opened on the waterproof strip, a fixing strip is slidably connected in the fixing hole, a linkage strip is slidably connected on the shell, and the linkage strip is located on the moving path of the fixing strip; when the fixing block is inserted into the fixing hole, the fixing strip protrudes and is located on the moving path of the linkage strip; when the linkage strip is inserted into the accommodating cavity, the fixing block is disengaged from the fixing hole.

[0017] By adopting the above technical solution, the fixing block is inserted into the fixing hole, so that the waterproof strip and the waterproof sponge are fixed to each other, and the separation of the waterproof sponge and the waterproof strip is avoided; the fixing block pushes the fixing bar to slide in the fixing hole, so that the fixing bar is located on the moving path of the linkage bar, so that the staff can drive the movement of the fixing bar through the linkage bar; when the staff slides the linkage bar, the linkage bar can push the fixing bar to move, so that the fixing bar drives the fixed block to move, and the fixed block is separated from the fixing hole, so that the waterproof sponge and the waterproof strip are separated, so that the waterproof strip can be replaced easily.

[0018] Optionally, a dovetail groove is provided on the waterproof strip, and a dovetail block is provided on the waterproof sponge; when the dovetail block is located in the dovetail groove, the waterproof sponge is fixed on the waterproof strip.

[0019] By adopting the above technical solution, the dovetail block is located in the dovetail groove, which increases the connection strength between the waterproof sponge and the waterproof strip, and further strengthens the firmness between the waterproof sponge and the waterproof strip.

[0020] Optionally, a waterproof spring is provided on the shell, a pushing block is provided on the waterproof spring, and the waterproof spring drives the waterproof sponge to abut against the operating rod through the pushing block.

[0021] By adopting the above technical solution, the push block is driven to move by the waterproof spring, so that the push block can abut against the waterproof sponge, and the waterproof sponge can abut against the outer surface of the operating rod; when the operating rod is rotated, there will be a certain friction between the operating rod and the waterproof sponge, so that the waterproof sponge will be worn by the operating rod.

[0028] The following is combined with Figure 1-5 This application is described in further detail.

[0029] This embodiment discloses a direct-acting circuit breaker that prevents accidental contact. Figure 1 A direct-acting circuit breaker with an anti-accidental touch function includes a housing 1, an operating rod 11 is rotatably connected to the housing 1, and a control structure 12 is fixedly connected to the housing 1. The rotation of the operating rod 11 can realize the opening and closing of the circuit through the control structure 12.

[0030] Reference Figure 1 and Figure 2 The housing 1 is provided with an accommodating chamber 2, and two waterproof blocks 212 are slidably connected in the accommodating chamber 2. The two waterproof blocks 212 are respectively located on the upper and lower sides of the operating rod 11.

[0031] Reference Figure 2 and Figure 3 A waterproof strip 21 is fixedly connected to the waterproof block 212. The curved waterproof strip 21 is located on the upper and lower sides of the operating rod 11, respectively. A dovetail groove 211 is defined on the end surface of each waterproof strip 21 facing the other waterproof strip 21. The dovetail groove 211 extends along the width of the waterproof strip 21 and extends to the side of the waterproof strip 21. A waterproof sponge 22 is detachably connected to the waterproof strip 21 and can absorb moisture from the operating rod 11. A dovetail block 221 is fixedly connected to the waterproof sponge 22 and can slide within the dovetail groove 211. When the dovetail block 221 is located within the dovetail groove 211, the waterproof sponge 22 is secured to the waterproof strip 21.

[0032] Reference Figure 2 and Figure 3 The housing 1 is provided with a sliding hole 23 that connects to the accommodating chamber 2. The sliding hole 23 extends in the vertical direction. A sliding block 231 is fixedly connected to the waterproof block 212. The sliding block 231 extends outside the housing 1 through the sliding hole 23. The sliding block 231 allows staff to move the waterproof strip 21.

[0033] Reference Figure 2 and Figure 4 A receiving groove 24 is defined on the end surface of each waterproof strip 21 facing the other waterproof strip 21. The receiving groove 24 extends along the length of the waterproof strip 21. A plurality of waterproof springs 241 are fixedly connected to the bottom wall of the receiving groove 24. The plurality of waterproof springs 241 are arranged in an array along the length of the receiving groove 24. A push block 242 is fixedly connected to the surface of the waterproof spring 241 away from the bottom wall of the receiving groove 24. The waterproof spring 241 drives the push block 242 to protrude out of the receiving groove 24.

[0034] Reference Figure 2The housing 1 is provided with two through-holes 25 communicating with the accommodating chamber 2. A movable bar 251 is slidably connected within the through-hole 25 and can be completely located within the through-hole 25. A resilient accommodating block 222 is fixedly connected to the surface of the waterproof sponge 22 and can be inserted into the through-hole 25.

[0035] Reference Figure 2 The housing 1 is provided with a movable groove 252 that communicates with the through-hole 25. The movable groove 252 allows the movable strip 251 to slide, and the movable groove 252 extends in the vertical direction. The movable strip 251 can move from the through-hole 25 into the movable groove 252, so that the movable strip 251 is not in the path of the waterproof sponge 22 from the accommodating chamber 2. At this time, the waterproof sponge 22 can be removed from the through-hole 25, thereby separating the waterproof sponge 22 from the waterproof strip 21.

[0036] Reference Figure 2 and Figure 4 The push block 242 has a push slope 243 on its surface facing the perforation 25. The distance between the push slope 243 and the perforation 25 gradually increases from one waterproof strip 21 to another. The push slope 243 is located in the insertion path of the waterproof sponge 22. When the waterproof sponge 22 is inserted into the accommodating cavity 2 through the perforation 25, the waterproof sponge 22 drives the push block 242 via the push slope 243, allowing the push block 242 to move into the accommodating groove 24, so that the push block 242 is located on the side of the waterproof sponge 22 facing the waterproof spring 241.

[0037] Reference Figure 2 、 Figure 4 and Figure 5 A fixing block 26 is integrally formed on the surface of the waterproof sponge 22, and a fixing hole 261 is formed on the surface of the waterproof strip 21 for inserting the fixing block 26. A fixing strip 262 is slidably connected to the fixing hole 261 and can be inserted into the fixing hole 261. When the fixing strip 262 is located in the fixing hole 261, the fixing block 26 can be separated from the fixing hole 261, and the waterproof sponge 22 and the waterproof strip 21 can be separated.

[0038] Reference Figure 5 The housing 1 is provided with a linkage hole 263 that communicates with the accommodating chamber 2. A linkage bar 264 is slidably connected to the linkage hole 263 and can be inserted into the accommodating chamber 2. A fixing bevel 265 is provided on the surface of the fixing bar 262 facing the linkage hole 263. The distance between the fixing bevel 265 and the linkage hole 263 gradually decreases from one waterproof strip 21 to another waterproof strip 21, and the fixing bevel 265 is located on the movement path of the linkage bar 264.

[0039] Reference Figure 5When the staff slides the linkage bar 264 and inserts the linkage bar 264 into the accommodating chamber 2, the linkage bar 264 drives the fixed bar 262 to move through the fixed inclined surface 265, allowing the fixed bar 262 to move in the fixing hole 261. At this time, the fixed bar 262 drives the fixed block 26 to move, separating the waterproof sponge 22 and the waterproof strip 21. At this time, the accommodating block 222 is located at the through-hole 25. The staff can pull the accommodating block 222 to take the waterproof sponge 22 out of the accommodating chamber 2 to replace the waterproof sponge 22.

[0040] Reference Figure 2 A stop plate 3 is slidably connected to the accommodating chamber 2 and slides vertically. A stop block 31 is fixedly connected to the surface of the stop plate 3. A stop groove 32 is defined on the outer surface of the operating rod 11 for the stop block 31 to be inserted into. When the stop block 31 is located in the stop groove 32, the operating rod 11 is fixed, making it difficult for the operator to rotate the operating rod 11.

[0041] Reference Figure 2 A first rack 33 is fixedly connected to the surface of the stop plate 3, and a second rack 34 is fixedly connected to the surface of the waterproof strip 21. A rotating gear 35 is meshed between the first rack 33 and the second rack 34. When the waterproof strip 21 slides downward until the waterproof sponge 22 abuts the operating lever 11, the second rack 34 drives the stop plate 3 to slide upward via the rotating gear 35 and the first rack 33, and the stop block 31 disengages from the stop groove 32.

[0042] The implementation principle of an anti-accidental-touch direct-acting circuit breaker in an embodiment of the present application is as follows: the staff drives the movement of the waterproof strip 21 through the sliding block 231. At this time, the waterproof strip 21 drives the first rack 33 to move through the second rack 34 and the rotating gear 35, so that the stop block 31 is located in the stop groove 32, thereby realizing the limitation of the operating rod 11 by the stop plate 3.
