[0025] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the following embodiments will specifically describe a circuit breaker switch assembly capable of indicating the initial state of the present utility model in conjunction with the accompanying drawings.

[0026] <Embodiment>

[0027] Figure 1 It is an assembly schematic diagram of a circuit breaker switch assembly capable of indicating the initial state in the embodiment of the present utility model; Figure 2 It is an exploded view of the structure of a circuit breaker switch assembly capable of indicating the initial state in the embodiment of the present utility model.

[0028] As Figure 1 and 2 shown, this embodiment provides a circuit breaker switch assembly 100 capable of indicating the initial state, including a circuit breaker switch 10, a backing plate 20, a rotating plate 30, an indication mark 40, an observation plate 50, a locking member 60 and a rotating handle 70.

[0029] The circuit breaker switch 10 is an ordinary circuit breaker switch as a whole, and it has a rotating shaft 10a capable of adjusting the opening and closing state.

[0030] The rotating shaft 10a is a prism with a square radial cross-section. By rotating the rotating shaft 10a, the opening and closing state of the circuit breaker switch 10 can be adjusted to the "open position", "0" or "closed position". Specifically, in this embodiment, the "open position" is at the -45° position, the "0" position is at the 0° position, and the "closed position" is at the 45° position.

[0031] The backing plate 20 is fastened to the circuit breaker switch 10 by a plurality of bolts, and a first through hole 20b is provided on the backing plate 20. The first through hole 20b can allow the rotating shaft 10a to pass through, and the inner diameter of the first through hole 20b is not less than the inner diameter of the radial cross-section of the rotating shaft 10a.

[0032] On the side of the backing plate 20 facing away from the circuit breaker switch 10, there is also a recessed groove with an opening facing away from the circuit breaker switch 10, denoted as the embedding groove 20a. Specifically, in this embodiment, the cross-section of the embedding groove 20a presents a shape formed by splicing a semicircle and a rectangle.

[0033] Figure 3 is a side plan view of the rotating plate and the indicating mark of the embodiment of the present utility model; Figure 4 is a three-dimensional view of the side of the rotating plate of the embodiment of the present utility model without the indicating mark.

[0034] Such as Figure 3 and 4 shown, the rotating plate 30 includes a main body 31, an axial protrusion 32, and an arc protrusion 33.

[0035] The main body 31 is a circular plate.

[0036] Such as Figures 1 to 4 shown, the axial protrusion 32 is a cylindrical protrusion provided on one side of the main body 31 and this cylindrical protrusion can be matched and passed through the first through hole 20b, and the axial protrusion 32 and the main body 31 are coaxial. The rotating plate 30 is rotatably arranged on the backing plate 20 and located in the embedding groove 20a through the matching of the axial protrusion 32 and the first through hole 20b.

[0037] The main body 31 and the axial protrusion 32 are provided with a special-shaped hole 31a along their axial directions for the rotating shaft 10a to be matched and passed through. Denote the side length of the square radial cross-section of the rotating shaft 10a as x, then the radial cross-section of the special-shaped hole 31a is composed of 4 45° arc edges with a diameter of and 8 straight edges with a length of , the 4 arc edges are evenly distributed in a circle, and two adjacent arc edges are connected by two concave straight edges.

[0038] The arc protrusion 33 extends on the main body 31 and is coplanar with the main body 31. Specifically, in this embodiment, the radian of the arc protrusion 33 is 90° and the arc protrusion 33 and the main body 31 are integrally formed.

[0039] In a variant of this embodiment, the arc protrusion 33 also has a ring that is detachably clamped with the main body 31. After clamping, the arc protrusion 33 can rotate together with the main body 31. The detachable matching design in the variant enables the arc protrusion 33 to be replaced conveniently, so as to adapt to the requirements of different subsequent indicating marks 40.

[0040] The indicating mark 40 is a groove recessed in the arc-shaped protrusion 33 and having a color smear, and the opening direction of the groove faces the side away from the axial protrusion 32. Specifically, the number of indicating marks 40 is 2, and the 2 indicating marks 40 have different color smears. The arc-shaped protrusion 33 is evenly divided into two parts according to the radian, and the 2 indicating marks 40 are respectively arranged on the two evenly divided parts of the arc-shaped protrusion 33.

[0041] The observation plate 50 is snap-fitted to the side of the backing plate 20 having the embedding groove 20a.

[0042] A second through hole 50a is provided on the observation plate 50. The second through hole 50a can be penetrated by the rotating shaft 10a, and the inner diameter of the second through hole 50a is not less than the inner diameter of the radial cross-section of the rotating shaft 10a.

[0043] An observation hole 50b is also provided on the observation plate 50. When the rotating plate 30 rotates around its axis, so that the 2 indicating marks 40 on the arc-shaped protrusion 33 are at different angles, different color smears corresponding to different indicating marks 40 can be clearly observed through the observation hole 50b.

[0044] The locking member 60 is a U-shaped frame with a curved side surface. Two end points of the U-shaped top of the locking member 60 are rotatably connected to the observation plate 50. Specifically, in this embodiment, the rotatable connection between the U-shaped locking member 60 and the observation plate 50 is located above the second through hole 50a; the radian of the curved side surface of the U-shaped locking member 60 faces downward.

[0045] Both sides of the U-shape of the locking member 60 have circular rings 60a with through holes, and the 2 circular rings 60a are used to cooperate together for the lock catch to pass through.

[0046] The rotating handle 70 includes a rotating part 71 and a holding part 72.

[0047] One end of the rotating part 71 has a groove (not shown in the figure) that matches the rotating shaft 10a and can be embedded therein, and a threaded hole 71a leading to the groove is provided on the side adjacent to the groove of the rotating part 71. By passing a bolt through the threaded hole 71a and the rotating shaft 10a embedded in the groove, the rotating part 71 and one end of the rotating shaft 10a are relatively fixed and can rotate coaxially.

[0048] The holding part 72 extends laterally from the other end of the rotating part 71 and is used for an operator to grasp and drive the rotating shaft 10a to rotate.

[0049] In this embodiment, when the rotating shaft 10a rotates to the opening / closing state of the circuit breaker switch 10 being in the "0" position, the holding portion 72 faces directly downward. At this time, the locking member 60 can be hooked on the holding portion 72, and its rotation is prevented from being grasped and manipulated through the arc-shaped U-shaped structure; meanwhile, the two circular rings 60a are located inside the planar space range formed by the rotating portion 71 and the holding portion 72.

[0050] The usage process of the circuit breaker switch assembly 100 that can indicate the initial state:

[0051] S10, pass the rotating shaft 10a of the circuit breaker switch 10 through the first through hole 20b, the special-shaped hole 31a, and the second through hole 50a in sequence, and connect and fix the holding portion 72 of the rotating handle 70 at the end of the rotating shaft 10a; meanwhile, each component is fixed through corresponding methods such as snap-fastening, rotatable embedding, and bolt connection, so as to assemble the circuit breaker switch assembly 100 that can indicate the initial state in this embodiment.

[0052] S20, connect the respective wiring terminals of the circuit breaker switch 10 in the circuit breaker switch assembly 100 that can indicate the initial state to the required lines correctly.

[0053] S30, rotate the holding portion 72 to drive the rotating shaft 10a to rotate to adjust the opening / closing state of the circuit breaker switch 10 to the "open position", "0", or "closed position". Specifically, in this embodiment, the "open position" is at the -45° position, the "0" position is at the 0° position, and the "closed position" is at the 45° position. When the holding portion 72 is at 0°, by observing the different coating colors of the indicating mark 40 through the observation hole 50b, it can be determined from which opening / closing state the circuit breaker switch 10 is adjusted to the 0 position at this time.

[0054] S40, hook the locking member 60 on the holding portion 72 at 0°, and then use a lock to pass through the two circular rings 60a, thereby restricting the rotatable direction of the holding portion 72 to prevent malicious operation or misoperation by external operators. Unlock and adjust it when using it next time.

[0055] Among them, in step S30 of the usage process of the circuit breaker switch assembly 100 that can indicate the initial state, through the following two demonstration illustrations, it is shown how the circuit breaker switch assembly 100 that can indicate the initial state in this embodiment indicates the initial state of the circuit breaker switch 10. Among them, the initial state refers to from which position ("open position" or "closed position") the circuit breaker switch 10 is adjusted to the current "0" position; there are two indicating marks 40 in total, with different colors respectively. Here, due to the limitation of the patent drawing format, the colors of the two indicating marks 40 are vividly expressed by m and n. Among them, the m color is used to represent red, indicating the open position at the -45° position; the n color is used to represent green, indicating the closed position at the 45° position.

[0056] The first demonstration schematic:

[0057] Figure 5 It is the first demonstration schematic diagram of the rotating plate, indicating mark and rotating shaft during the use of a circuit breaker switch assembly capable of indicating the initial state in an embodiment of the present utility model.

[0058] As Figure 5 shown:

[0059] 1. Figure 5 In Figure a of

[15] : The initial state of the circuit breaker switch 10 is at the "0" position. At this time, color m can be observed through the observation hole 50b.

[0060] 2. Figure 5 In Figure b of

[15] : Rotate the rotating shaft 10a in

[15] counterclockwise by 45°. Due to the special shape of the irregular hole 31a, the rotating shaft 10a drives the main body 31 and the arc-shaped protrusion 33 to rotate counterclockwise by 45° together through the irregular hole 31a. At this time, the opening and closing state of the circuit breaker switch 10 is the closing position, and color n corresponding to the indicating mark 40 in the closing position state can be observed through the observation hole 50b.

[0061] Subsequently, the operator can determine that the opening and closing state of the circuit breaker switch 10 is the closing position via color n and the 45° angle where the holding part 72 is located.

[0062] 3. Figure 5 In Figure c of

[15] : Rotate the rotating shaft 10a in

[15] clockwise by 45°. At this time, due to the special shape of the irregular hole 31a, the main body 31 and the arc-shaped protrusion 33 will not be driven to rotate by the rotating shaft 10a. The indicating mark 40 observed through the observation hole 50b is still color n in the closing position of the previous initial state.

[0063] Subsequently, the operator can determine through the 0° angle where the holding part 72 is located and color n in the closing position that: the circuit breaker switch 10 at the "0" position at this time is adjusted from the closing position corresponding to color n.

[0064] 4. Figure 5 In Figure d of

[15] : Rotate the rotating shaft 10a in

[15] clockwise by 45°. At this time, due to the special shape of the irregular hole 31a, the rotating shaft 10a drives the main body 31 and the arc-shaped protrusion 33 to rotate clockwise by 45° together through the irregular hole 31a. At this time, the opening and closing state of the circuit breaker switch 10 is the opening position, and color m corresponding to the indicating mark 40 in the opening position state can be observed through the observation hole 50b.

[0065] Subsequently, the operator can determine that the opening and closing state of the circuit breaker switch 10 is the opening position via color m and the -45° angle where the holding part 72 is located.

[0066] 5. Figure 5Figure e in [reference]: Rotate the rotating shaft 10a in Figure d counterclockwise by 45°. Due to the special shape of the irregular hole 31a, the main body 31 and the arc-shaped protrusion 33 will not be driven to rotate by the rotating shaft 10a. The indicating mark 40 observed through the observation hole 50b is still the m color at the opening position in the initial state of the previous step.

[0067] Subsequently, the operator can determine that the circuit breaker switch 10 at the "0" position at this time is adjusted from the opening position corresponding to the m color by means of the 0° angle where the holding part 72 is located and the m color at the opening position.

[0071] 2. Figure 6 In Figure (2) in [reference], the circuit breaker switch 10 is at the opening position, and the m color at the opening position can be observed through the observation hole 50b.

[0072] 3. Figure 6 In Figure (3) in [reference], the circuit breaker switch 10 is at the "0" position. By combining the m color at the opening position observed through the observation hole 50b, it is determined that the circuit breaker switch 10 is adjusted from the opening position to the "0" position.

Within a set rotation angle range, the rotating plate does not rotate following the rotation of the rotating shaft passing through the special-shaped hole, and when exceeding the set rotation angle range, the rotating plate rotates following the rotation of the rotating shaft passing through the special-shaped hole; two indicating marks provided on the rotating plate, corresponding to the opening and closing states of the "open position" and "closed position" of the circuit breaker switch respectively; and an observation plate with an observation hole provided thereon, the observation hole corresponding to the indicating marks. When the rotating shaft rotates to make the opening and closing state of the circuit breaker switch change from "0" to "open position" or from "0" to "closed position", different indicating marks correspond in the observation hole. When the rotating shaft rotates to make the opening and closing state of the circuit breaker switch change from "open position" to "0" or from "closed position" to "0", the indicating marks in the observation hole do not change.

[0079] Therefore, a circuit breaker switch assembly capable of indicating the initial state in this embodiment can clearly and intuitively observe and confirm its specific state through the indicating marks when the circuit breaker switch is in the open position or the closed position. Moreover, a circuit breaker switch assembly capable of indicating the initial state in this embodiment can determine whether the circuit breaker switch is adjusted from the "open position" or the "closed position" to the "0" position specifically.

[0080] Further, the set rotation angle is 45°. The radial cross-section of the rotating shaft is square, and the side length of the square is denoted as x. The special-shaped hole is composed of 4 45° arc edges with a diameter of and 8 straight edges with a length of . The 4 arc edges are evenly distributed in a circle, and two adjacent arc edges are connected by two concave straight edges. The central axis of the rotating shaft passes through the center of the arc edge. The special shape design of the special-shaped hole can ensure that when the rotating shaft rotates to make the opening and closing state of the circuit breaker switch change from "open position" to "0" or from "closed position" to "0", the indicating marks in the observation hole will not change.

[0081] Further, the rotating plate has a co-planar arc-shaped protrusion on the side, and the radian of the arc-shaped protrusion is greater than 45°. The arc-shaped protrusion is evenly divided into two arcs, and different indicating marks are set on the two arcs. Such a setting makes the area of the indicating marks larger, easier to be observed correspondingly through the observation hole, and not difficult to observe due to insufficient rotation angle.

[0082] Further, the indicating mark is an integrally formed groove with a pigment coating. This setting makes it clearer and more convenient for the operator to observe the indicating mark.

[0083] Further, the circuit breaker switch assembly capable of indicating the initial state further includes a rotating handle, and the rotating handle includes: a rotating part fixedly connected to one end of the rotating shaft passing through the observation plate for driving the rotation of the rotating shaft; and a holding part laterally extending on the rotating part for the operator to grasp to drive the rotation of the rotating part. This setting enables the operator to more conveniently rotate the rotating shaft to adjust the opening and closing state of the circuit breaker switch.

[0084] Further, the circuit breaker switch assembly capable of indicating the initial state further includes a locking member. The locking member is a "U"-shaped bracket with a curvature, and the two end points at the top thereof are rotatably arranged on the observation plate. When the rotating handle rotates the rotating shaft to make the opening and closing state of the circuit breaker switch "0", the locking member is hooked on the holding part to prevent it from rotating. This setting enables the holding part to be fixed at the 0 position and prevents unnecessary misoperations.

[0085] Further, rings with through holes are provided on both sides of the "U" shape of the locking member. The rings are located between the holding part and the observation plate, and the rings on both sides of the "U" shape of the locking member are used to cooperate with each other for the lock catch to pass through. This setting can effectively prevent external personnel from rotating the holding part after lifting the locking member, reducing the possibility of malicious operation or misoperation.

[0086] Further, gaskets of the same and / or different specifications are provided between the components of the circuit breaker switch assembly capable of indicating the initial state. This setting can reduce the relative vibration between the components.

[0087] Further, the connection methods between the components of the circuit breaker switch assembly capable of indicating the initial state include any one or more of rotatable insertion, snap connection, or bolt fixation. This setting enables the components to be detachably and firmly connected.
