Description

Technical Field

[0001] This application relates to the field of handle technology, and more particularly to a handle and circuit system. Background Technology

[0002] The circuit system may include an indicator structure. This indicator structure is used to indicate the state of the circuit system. The circuit system may include an open state and a closed state. When the circuit system is in the open state, no current flows through it. When the circuit system is in the closed state, current flows through it. Therefore, the circuit system also includes a handle. The operator can control the flow of current in the circuit system by turning the handle.

[0003] In related technologies, the indicator components in the indicator structure may become loose or fall off, causing the status of the circuit system to be unable to be accurately fed back, thereby affecting the operator's judgment of the status of the circuit system and creating potential safety hazards in the circuit system. Utility Model Content

[0004] This application provides a handle and circuit system that can prevent the indicator from becoming loose or falling off, accurately reflect the status of the circuit system, improve the operator's accuracy in judging the status of the circuit system, and reduce the safety hazards existing in the circuit system.

[0005] In a first aspect, this application provides a handle, comprising: a handle, a base, an interlocking structure, and an indicating structure. The bottom of the handle is rotatably connected to the base, allowing the handle to rotate along a first pivot, wherein the first pivot is perpendicular to the base. The handle has a receiving groove. The interlocking structure is disposed within the receiving groove to restrict the rotation of the handle. The indicating structure includes an indicating element, a first mark, and a second mark. The indicating element is disposed on the interlocking structure, and the interlocking structure and the indicating element are integrally formed. The first mark and the second mark are disposed on the base. The interlocking structure rotates together with the handle along the first pivot, causing the indicating element to point to either the first mark or the second mark.

[0006] The first aspect of this application provides a handle comprising a grip, a base, an interlocking structure, and an indicating structure. The bottom of the grip is rotatably connected to the base, allowing the grip to rotate along a first pivot, thereby switching the circuit system connected to the grip from an open / closed state to a closed / open state. The first pivot is perpendicular to the base. A receiving groove is provided on the grip, and the interlocking structure is disposed within the receiving groove. The interlocking structure can rotate with the grip, restricting the grip's rotation at any position. By restricting the grip's rotation, the interlocking structure prevents the circuit system connected to the grip from switching between closed and open states, thus avoiding safety issues caused by operator misoperation of the grip and improving the safety of the circuit system. An indicator in the indicating structure is disposed on the interlocking structure, rotating with the grip and pointing to a first or second indicator disposed on the base, allowing the operator to determine the state of the circuit system by the position of the indicator. The interlocking structure and the indicator are integrated into one unit, which can prevent the indicator from becoming loose or falling off, and enable the indicator to accurately reflect the status of the circuit system. This improves the operator's accuracy in judging the status of the circuit system and reduces potential safety hazards in the circuit system.

[0007] In one possible design, a slider is provided at one end of the interlocking structure near the base. A limiting groove is provided on the base, with its wall aligned with the rotation direction of the handle. A receiving groove is a through groove extending along a first direction; one end of the slider is fitted into the receiving groove through the through groove, and the other end of the limiting groove is fitted into the receiving groove. The slider moves towards the limiting groove until it is located within the limiting groove, where the wall of the limiting groove restricts the slider's movement along the rotation direction of the handle. Here, the first direction is the height direction of the base.

[0008] Based on the description of the above embodiments, a slider is provided at one end of the interlocking structure near the base, and a limiting groove is provided on the base. The slider is located in the limiting groove, and the groove wall of the limiting groove is used to limit the rotation of the slider, the interlocking structure, and the handle along the first rotating shaft, thereby avoiding safety problems caused by operator misoperation of the handle and improving the safety of the circuit system.

[0009] In one possible design, a first pin hole is provided on the side wall of the receiving groove. A second pin hole is provided on the interlocking structure. A rotating pin connects between the first and second pin holes, causing the interlocking structure to rotate along a second pivot in the receiving groove, creating a first or second angle between the interlocking structure and the base. The second pivot is parallel to the base. When the first angle exists between the interlocking structure and the base, the slider is located within the limiting groove, locking the handle. When the second angle exists between the interlocking structure and the base, the slider is located outside the limiting groove, unlocking the handle.

[0010] Based on the description of the above embodiments, the rotating pin connects the first pin hole provided on the receiving groove and the second pin hole provided on the interlocking structure, allowing the interlocking structure to rotate along the second rotating shaft until a second angle exists between the interlocking structure and the base. At this point, the slider slides out of the limiting groove, allowing the slider, interlocking structure, and handle to rotate smoothly along the first rotating shaft, thus placing the handle in the unlocked state. When the interlocking structure rotates along the second rotating shaft until a first angle exists between the interlocking structure and the base, the slider slides into the limiting groove, preventing the slider, interlocking structure, and handle from rotating along the first rotating shaft, thus placing the handle in the locked state.

[0011] In one possible design, a first mounting block is provided within the receiving groove. A second mounting block is provided within the interlocking structure. A tension spring connects the first and second mounting blocks. When a first angle exists between the interlocking structure and the base, the tension spring is in a stretched state. When a second angle exists between the interlocking structure and the base, the tension spring is in its initial state.

[0012] Based on the description of the above embodiments, a first mounting block is provided in the receiving groove, a second mounting block is provided in the interlocking structure, and a tension spring is connected between the first mounting block and the second mounting block, so that the tension spring can obtain tensile force through the rotation of the interlocking structure, and the numerical range of the first angle can be selected by setting the elastic coefficient of the tension spring.

[0013] In one possible design, the interlocking structure has a locking hole at the end furthest from the slider. The locking hole is used to install a limiting member. When the handle is in the unlocked state, the locking hole is inside the receiving groove, preventing the limiting member from being installed. When the handle is in the locked state, the locking hole is exposed outside the receiving groove, allowing the limiting member to be installed. The limiting member engages outside the receiving groove to prevent the interlocking structure from continuing to rotate along the second shaft.

[0014] Based on the description of the above embodiments, the locking hole at the end of the interlocking structure away from the slider is used to install a limiting member. The limiting member is used to keep the handle in the locked state, thereby preventing the circuit system from switching between the closed and open states, thus avoiding safety problems caused by operator misoperation of the handle and improving the safety of the circuit system.

[0015] In one possible design, the interlocking structure can be T-shaped, comprising a first section and a second section perpendicular to each other. A keyhole is located at one end of the first section. An indicator is located at the other end of the first section. One end of the through-slot is a window opened at the top of the handle, for observing the indicator. A slider is located at one end of the second section. A second pin hole is located at the other end of the second section, and the other end of the second section is connected to the middle of the first section.

[0016] Based on the description of the above embodiments, the interlocking structure is T-shaped, comprising a first section and a second section. The lock hole is located at one end of the first section, the indicator is at the other end of the first section, the slider is located at one end of the second section, the second pin hole is located at the other end of the second section, and one end of the through slot is a window located at the top of the handle. This allows the operator to accurately determine whether the handle is locked or unlocked by observing the relative position of the lock hole and the window. Furthermore, since the indicator is located at the other end of the first section, the interlocking structure and the indicator are integrated, preventing the indicator from becoming loose or falling off. This ensures the indicator accurately reflects the status of the circuit system, thereby improving the operator's accuracy in judging the circuit system's status and reducing potential safety hazards within the circuit system.

[0017] In one possible design, the first angle is greater than or equal to 10°.

[0018] Based on the description of the above embodiments, a first angle greater than or equal to 10° can ensure that the lock hole is fully exposed, thereby enabling the limiting member to be installed smoothly, so as to achieve the function of restricting the handle to the locked state through the interlocking structure.

[0019] In one possible design, a reflective strip is attached to the other end of the first section.

[0020] Based on the description of the above embodiments, a reflective strip is attached to the other end of the first section, so that the operator can see the position of the first section, i.e. the indicator, in a dim environment, thereby accurately judging the status of the circuit system and reducing the safety hazards in the circuit system.

[0021] In one possible design, one end of the first segment is connected to an abutment. The abutment extends along a first direction and toward the base. A protruding structure is provided on the abutment. When the handle is in the unlocked state, the abutment abuts against the inner wall of the through groove. When the handle is in the locked state, the distance between the protruding structure and the inner wall of the through groove is less than or equal to 0.5 mm.

[0022] Based on the description of the above embodiments, the abutment portion connected to one end of the first segment and the abutment portion having a protruding structure are used to prevent most impurities from entering the circuit system when the handle is in the unlocked state and the locked state, thereby improving the protection level of the circuit system.

[0023] Secondly, this application provides a circuit system including a handle as described in any of the above embodiments, the handle being used to control the on / off state of current in the circuit system.

[0024] The beneficial effects of the circuit system provided in the second aspect above can be found in the first aspect and the beneficial effects of various possible implementations of the first aspect, and will not be repeated here. Attached Figure Description

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0042] The terms "comprising" and "having," and any variations thereof, used in the specification, claims, and drawings of this application are intended to cover without excluding other meanings. The words "a" or "an" do not exclude the presence of multiples.

[0043] The term "embodiment" as used herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of the phrase "embodiment" in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0044] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0045] The directional terms appearing in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of this application. For example, in the description of this application, terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figures. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0046] Furthermore, the descriptions of directions such as the X direction, Y direction, and Z direction used to explain the operation and construction of the components in this embodiment are not absolute but relative. Although these directions are appropriate when the components are in the positions shown in the figure, they should be interpreted differently when these positions change to correspond to the changes.

[0047] Furthermore, the terms "first," "second," etc., in the specification and claims of this application or in the aforementioned drawings are used to distinguish different objects rather than to describe a specific order, and may explicitly or implicitly include one or more of the features.

Signal connection can refer not only to signal connection through a circuit but also to signal connection through a media, such as radio waves. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0050] The circuit system may include an indicator structure. This indicator structure is used to indicate the state of the circuit system. The circuit system may include an open state and a closed state. When the circuit system is in the open state, no current flows through it. When the circuit system is in the closed state, current flows through it. Therefore, the circuit system also includes a handle. The operator can control the flow of current in the circuit system by turning the handle.

[0051] For example, the circuit system can be the circuit system in equipment such as circuit breakers, distribution boxes, or electronic switches, without being specifically limited here.

[0052] In related technologies, the indicator components in the indicator structure may become loose or fall off, causing the status of the circuit system to be unable to be accurately fed back, thereby affecting the operator's judgment of the status of the circuit system and creating potential safety hazards in the circuit system.

[0053] Based on this, this application provides a handle and circuit system. By integrating the indicator and handle into a single structure, the indicator is prevented from becoming loose or falling off, allowing it to accurately reflect the status of the circuit system. This improves the operator's accuracy in judging the circuit system's status and reduces potential safety hazards within the circuit system. The following is a detailed explanation... Figure 1-6 Please provide a detailed explanation.

[0054] In a first aspect, this application provides a handle 100, comprising: a handle 1, a base 2, an interlocking structure 3, and an indicating structure. The bottom of the handle 1 is rotatably connected to the base 2, allowing the handle 1 to rotate along a first axis of rotation, wherein the first axis of rotation is perpendicular to the base 2. The handle 1 has a receiving groove 11. The interlocking structure 3 is disposed within the receiving groove 11 to restrict the rotation of the handle 1. The indicating structure includes an indicating element 31, a first mark 21, and a second mark 22. The indicating element 31 is disposed on the interlocking structure 3, and the interlocking structure 3 and the indicating element 31 are integrally formed. The first mark 21 and the second mark 22 are disposed on the base 2. The interlocking structure 3 rotates together with the handle 1 along the first axis of rotation, causing the indicating element 31 to point to either the first mark 21 or the second mark 22.

[0055] like Figure 1 and Figure 2 As shown, the handle 100 may include a handle 1, a base 2, and an interlocking structure 3.

[0056] The base 2 is connected to the outer casing of the circuit system, and the base 2 can also be part of the outer casing of the circuit system. For example, the base 2 can be part of the circuit breaker casing or the electronic switch casing.

[0057] Handle 1 is mechanically connected to the circuit system and is used to control the flow of current in the circuit system. For example, handle 1 can be connected to the contact assembly in a circuit breaker. Handle 1 actuates the contact assembly, thereby controlling the flow of current in the circuit breaker. When no current flows through the circuit system, the circuit system is in an open state. When current flows through the circuit system, the circuit system is in a closed state. In other words, handle 1 can be used to switch the state of the circuit system, changing it from an open / closed state to a closed / open state.

[0058] Specifically, such as Figure 2 As shown, the bottom of the handle 1 is rotatably connected to the base 2, allowing the handle 1 to rotate along the first axis, thereby switching the state of the circuit system. The first axis is perpendicular to the base 2.

[0059] Furthermore, the trajectory points of the handle 1 rotation can include a first position point and a second position point. When the handle 1 is stationary at the first position point, it indicates that the circuit system is in an open state. Rotating the handle 1 to the second position point at this time can switch the circuit system from an open state to a closed state. Similarly, when the handle 1 is stationary at the second position point, it indicates that the circuit system is in a closed state. Rotating the handle 1 to the first position point at this time can switch the circuit system from a closed state to an open state.

[0060] The interlocking structure 3 is used to restrict the rotation of the handle 1, and the interlocking structure 3 can rotate together with the handle 1 along the first axis. Specifically, as shown... Figure 2 As shown, the handle 1 is provided with a receiving groove 11, and the interlocking structure 3 is disposed within the receiving groove 11. Figure 1 and Figure 2 As shown, when the handle 1 rotates along the first axis, the inner wall of the receiving groove 11 can abut against the interlocking structure 3, allowing the interlocking structure 3 to rotate together with the handle 1. This means that the handle 1 can be restricted from rotating at any position by the interlocking structure 3. For example, when the handle 1 is at the first position, the interlocking structure 3 can restrict the handle 1 from rotating. When the handle 1 is at the second position, the interlocking structure 3 can also restrict the handle 1 from rotating.

[0061] Furthermore, the interlocking structure 3 allows the handle 1 to exist in two states: a locked state and an unlocked state. When the handle 1 is in the locked state, the interlocking structure 3 is fixed to the base 2, preventing the handle 1 from rotating along the first axis. When the handle 1 is in the unlocked state, the interlocking structure 3 and the base 2 can rotate relative to each other, allowing the interlocking structure 3 to rotate together with the handle 1 along the first axis.

[0062] Therefore, when handle 1 is in the locked state, handle 1 cannot be rotated from the first position point / second position point to the second position point / first position point. This prevents the circuit system from switching between the closed and open states, thereby avoiding safety problems caused by operator misoperation of handle 1 and improving the safety of the circuit system.

[0063] Furthermore, the handle 100 may also include an indicating structure. The indicating structure may include an indicating element 31, a first identifier 21, and a second identifier 22. Wherein, as... Figure 1As shown, both the first indicator 21 and the second indicator 22 are mounted on the base 2. The indicator 31 rotates together with the handle 1. When the handle 1 is rotated to the first position, the indicator 31 points to the first indicator 21; when the handle 1 is rotated to the second position, the indicator 31 points to the second indicator 22. That is, when the indicator 31 points to the first indicator 21, it indicates that the circuit system is in an open state; when the indicator 31 points to the second indicator 22, it indicates that the circuit system is in a closed state. Therefore, the operator can determine the status of the circuit system by the position of the indicator 31.

[0064] However, if the indicator 31 becomes loose or falls off, the operator will be unable to determine the status of the circuit system through the indicator 31, which may lead to safety problems caused by misoperation of the handle 1. Based on this, in order to improve the safety of the circuit system, the indicator 31 in this application can be set on the interlocking structure 3. Since the interlocking structure 3 can rotate together with the handle 1 along the first rotating shaft, the indicator 31 can also rotate together with the handle 1.

[0065] Furthermore, the interlocking structure 3 and the indicator 31 are an integral structure, which can prevent the indicator 31 from becoming loose or falling off, enabling the indicator 31 to accurately reflect the status of the circuit system, thereby improving the accuracy of the operator's judgment of the circuit system status and reducing potential safety hazards in the circuit system. For example, the interlocking structure 3 and the indicator 31 can be integrally molded using an injection molding process.

[0066] In summary, the handle 100 provided in the first aspect of this application includes a handle 1, a base 2, an interlocking structure 3, and an indicating structure. The bottom of the handle 1 is rotatably connected to the base 2, allowing the handle 1 to rotate along a first axis, thereby switching the circuit system connected to the handle 100 from an open / closed state to a closed / open state. The first axis is perpendicular to the base 2. The handle 1 has a receiving groove 11, and the interlocking structure 3 is disposed within the receiving groove 11. The interlocking structure 3 can rotate with the handle 1, restricting the rotation of the handle 1 at any position. By restricting the rotation of the handle 1, the interlocking structure 3 prevents the circuit system connected to the handle 100 from switching between a closed and open state, thus avoiding safety issues caused by operator error and improving the safety of the circuit system. The indicating element 31 in the indicating structure is disposed on the interlocking structure 3, rotating with the handle 1 and pointing to either a first indicator 21 or a second indicator 22 disposed on the base 2, allowing the operator to determine the state of the circuit system by the position of the indicating element 31. The interlocking structure 3 and the indicator 31 are an integral structure, which can prevent the indicator 31 from becoming loose or falling off, and enable the indicator 31 to accurately reflect the status of the circuit system, thereby improving the accuracy of the operator's judgment of the status of the circuit system and reducing the safety hazards in the circuit system.

[0067] Optionally, this application may define the specific structure of the interlocking structure 3 as follows:

[0068] In some embodiments, a slider 32 is provided at one end of the interlocking structure 3 near the base 2. A limiting groove 23 is provided on the base 2, with its wall arranged along the rotation direction of the handle 1. The receiving groove 11 is a through groove extending along a first direction X. The slider 32 is fitted into the receiving groove 11 through one end of the through groove, and the limiting groove 23 is fitted into the receiving groove 11 through the other end of the through groove. The slider 32 moves towards the limiting groove 23 until it is located within the limiting groove 23, where the wall of the limiting groove 23 restricts the slider 32 from moving along the rotation direction of the handle 1. Here, the first direction X is the height direction of the base 2.

[0069] like Figure 2 As shown, a slider 32 is provided at one end of the interlocking structure 3 near the base 2. Figure 2 As shown, a limiting groove 23 is provided on the base 2. The slider 32 can slide into or out of the limiting groove 23. Figure 3 As shown, when the slider 32 slides into the limiting groove 23, the limiting groove 23 is set on the groove wall in the rotation direction of the handle 1 to abut against the slider 32, restricting the slider 32 and the interlocking structure 3 from rotating along the first rotating shaft, thereby restricting the interlocking structure 3 from driving the handle 1 to rotate along the first rotating shaft, so that the handle 1 is in a locked state and cannot switch the closed state and open state of the circuit system, thereby avoiding safety problems caused by the operator's misoperation of the handle 1 and improving the safety of the circuit system.

[0070] In addition, when the slider 32 is outside the limiting groove 23, the groove wall of the limiting groove 23 cannot abut against the slider 32, thus preventing the slider 32 and the interlocking structure 3 from rotating along the first axis. As a result, the interlocking structure 3 can smoothly drive the handle 1 to rotate along the first axis, thereby putting the handle 1 in the unlocked state and smoothly switching the closed and open states of the circuit system.

[0071] Furthermore, the receiving groove 11 is a through groove that extends along the first direction X. The slider 32 is sleeved in the receiving groove 11 through one end of the through groove, and the limiting groove 23 is sleeved in the receiving groove 11 through the other end of the through groove, so that both the slider 32 and the limiting groove 23 are located in the receiving groove 11, thereby enabling the slider 32 to enter the limiting groove 23, so as to realize the function of the interlocking structure 3 to restrict the rotation of the handle 1.

[0072] refer to Figure 1 The first direction X is the height direction of the base 2.

[0073] According to the description of the above embodiment, a slider 32 is provided at one end of the interlocking structure 3 near the base 2. A limiting groove 23 is provided on the base 2. The slider 32 is located in the limiting groove 23. The groove wall of the limiting groove 23 is used to limit the rotation of the slider 32, the interlocking structure 3 and the handle 1 along the first rotating shaft, thereby avoiding safety problems caused by the operator's misoperation of the handle 1 and improving the safety of the circuit system.

[0074] Furthermore, the connection method between the interlocking structure 3 and the handle 1 can be improved in the following ways:

[0075] In some embodiments, a first pin hole 12 is provided on the side wall of the receiving groove 11. A second pin hole 33 is provided on the interlocking structure 3. A rotating pin 4 is connected between the first pin hole 12 and the second pin hole 33, causing the interlocking structure 3 to rotate along a second rotating axis in the receiving groove 11, creating a first angle α or a second angle between the interlocking structure 3 and the base 2. The second rotating axis is parallel to the base 2. When there is a first angle α between the interlocking structure 3 and the base 2, the slider 32 is located within the limiting groove 23, keeping the handle 1 in a locked state. When there is a second angle between the interlocking structure 3 and the base 2, the slider 32 is located outside the limiting groove 23, keeping the handle 1 in an unlocked state.

[0076] like Figure 2 As shown, a first pin hole 12 is provided on the side wall of the receiving groove 11, and a second pin hole 33 is provided on the interlocking structure 3. Figure 4 As shown, the rotating pin 4 is connected between the first pin hole 12 and the second pin hole 33, causing the interlocking structure 3 to rotate along the second rotating shaft in the receiving groove 11, thereby creating a first angle α or a second angle between the interlocking structure 3 and the base 2. The second rotating shaft is parallel to the base 2.

[0077] refer to Figure 5 It can be seen that when the interlocking structure 3 rotates along the second axis until there is a first angle α between the interlocking structure 3 and the base 2, the slider 32 can slide into the limiting groove 23, so that the slider 32, the interlocking structure 3 and the handle 1 cannot rotate along the first axis, thereby putting the handle 1 in a locked state.

[0078] When the interlocking structure 3 rotates along the second axis until there is a second angle between the interlocking structure 3 and the base 2, the slider 32 can slide out of the limiting groove 23, so that the slider 32, the interlocking structure 3 and the handle 1 can rotate smoothly along the first axis, thereby putting the handle 1 in the unlocked state.

[0079] According to the description of the above embodiment, the rotating pin 4 is connected between the first pin hole 12 provided on the receiving groove 11 and the second pin hole 33 provided on the interlocking structure 3, so that the interlocking structure 3 can rotate along the second rotating axis until there is a second angle between the interlocking structure 3 and the base 2. At this point, the slider 32 slides out of the limiting groove 23, so that the slider 32, the interlocking structure 3 and the handle 1 can rotate smoothly along the first rotating axis, thereby putting the handle 1 in the unlocked state. When the interlocking structure 3 rotates along the second rotating axis until there is a first angle α between the interlocking structure 3 and the base 2, the slider 32 slides into the limiting groove 23, so that the slider 32, the interlocking structure 3 and the handle 1 cannot rotate along the first rotating axis, thereby putting the handle 1 in the locked state.

[0080] Furthermore, in some embodiments, a first mounting block 13 is provided within the receiving groove 11. A second mounting block 34 is provided within the interlocking structure 3. A tension spring 5 connects the first mounting block 13 and the second mounting block 34. When there is a first angle α between the interlocking structure 3 and the base 2, the tension spring 5 is in a stretched state. When there is a second angle between the interlocking structure 3 and the base 2, the tension spring 5 is in its initial state.

[0081] like Figure 5 As shown, a first mounting block 13 is provided in the receiving groove 11, and a second mounting block 34 is provided in the interlocking structure 3. And as... Figure 5 As shown, a tension spring 5 connects the first mounting block 13 and the second mounting block 34.

[0082] The first mounting block 13 is fixedly connected within the receiving groove 11, and the second mounting block 34 is fixedly connected within the interlocking structure 3. The fixed connection can be welding, snap-fitting, screwing, or injection molding; no specific limitation is made here.

[0083] Furthermore, the tension spring 5 may include a first end and a second end. The first end is connected to the first mounting block 13, and the second end is connected to the second mounting block 34, connecting the tension spring 5 between the first mounting block 13 and the second mounting block 34. This allows the tension spring 5 to obtain tensile force through the rotation of the interlocking structure 3. Specifically, when the tension spring 5 changes from its initial state to its stretched state, a tensile force needs to be applied to the tension spring 5. Therefore, when there is a first angle α between the interlocking structure 3 and the base 2, the tension spring 5 bears the tensile force from the interlocking structure 3.

[0084] Furthermore, the larger the spring constant of the tension spring 5, the greater the tensile force required for the tension spring 5 to change from its initial state to its stretched state. Conversely, the operator can select different initial angles α by choosing tension springs 5 ​​with different spring constants.

[0085] In other words, the range of values ​​for the first angle α can be selected by setting the spring constant of the tension spring 5. The range of values ​​for the first angle α includes the maximum value of the first angle α, the minimum value of the first angle α, and all values ​​between the maximum and minimum values ​​of the first angle α.

[0086] According to the description of the above embodiment, the receiving groove 11 is provided with a first mounting block 13, the interlocking structure 3 is provided with a second mounting block 34, and the tension spring 5 is connected between the first mounting block 13 and the second mounting block 34, so that the tension spring 5 can obtain tensile force through the rotation of the interlocking structure 3, and the value range of the first angle α can be selected by setting the elastic coefficient of the tension spring 5.

[0087] Furthermore, in some embodiments, a locking hole 35 is provided at the end of the interlocking structure 3 away from the slider 32. The locking hole 35 is used to install a limiting member. When the handle 1 is in the unlocked state, the locking hole 35 is located inside the receiving groove 11, preventing the limiting member from being installed. When the handle 1 is in the locked state, the locking hole 35 is exposed outside the receiving groove 11, allowing the limiting member to be installed. The limiting member engages with the outside of the receiving groove 11 to prevent the interlocking structure 3 from continuing to rotate along the second pivot.

[0088] like Figure 6 As shown, the end of the interlocking structure 3 furthest from the slider 32 is provided with a locking hole 35, in which a limiting element can be installed. The limiting element can be one or more mechanical locks or latching blocks; no specific limitation is made here.

[0089] When there is a first angle α between the interlocking structure 3 and the base 2, the handle 1 is in the locked state. Figure 4 As shown, the lock hole 35 is exposed outside the receiving groove 11, allowing the locking hole 35 to accommodate the limiting member. The limiting member is installed in the lock hole 35 and engaged outside the receiving groove 11, preventing the interlocking structure 3 from rotating along the second axis. This maintains the angle between the interlocking structure 3 and the base 2 at the first angle α, and prevents the interlocking structure 3 from rotating to the point where a second angle exists between them. In other words, when the limiting member is engaged outside the receiving groove 11, the handle 1 remains in the unlocked state and cannot be unlocked.

[0090] When there is a second angle between the interlocking structure 3 and the base 2, the handle 1 is in the unlocked state. For example... Figure 1 As shown, at this time, the lock hole 35 is located inside the receiving groove 11, and the limiting member cannot enter the receiving groove 11. Therefore, the limiting member cannot be installed in the lock hole 35 at this time.

[0091] In summary, the limiting component is used to keep the handle 1 in the locked state, thereby preventing the circuit system from switching between the closed and open states, thus avoiding safety problems caused by operator misoperation of the handle 1 and improving the safety of the circuit system.

[0092] As described in the above embodiment, the locking hole 35 at the end of the interlocking structure 3 away from the slider 32 is used to install a limiting member. The limiting member is used to keep the handle 1 in the locked state, thereby preventing the circuit system from switching between the closed and open states, thus avoiding safety problems caused by operator misoperation of the handle 1 and improving the safety of the circuit system.

[0093] Specifically, in some embodiments, the interlocking structure 3 can be T-shaped, including a first segment 311 and a second segment 312 that are perpendicular to each other. A lock hole 35 is located at one end of the first segment 311. An indicator 31 is located at the other end of the first segment 311. One end of the through slot is a window 111 opened at the top of the handle 1, the window 111 being used to observe the indicator 31. A slider 32 is located at one end of the second segment 312. A second pin hole 33 is opened at the other end of the second segment 312, and the other end of the second segment 312 is connected to the middle of the first segment 311.

[0094] Interlocking structure 3 is T-shaped, such as Figure 6 As shown, the T-shaped interlocking structure 3 may include a first section 311 and a second section 312 that are perpendicular to each other, and the other end of the second section 312 is connected to the middle of the first section 311.

[0095] Furthermore, the window 111 can be one end of the through slot near the top of the handle 1, through which the operator can observe the first section 311 of the interlocking structure 3.

[0096] Therefore, when the interlocking structure 3 rotates along the other end of the second section 312, one end of the first section 311 protrudes out of / into the window 111 provided at the top of the handle 1, and the other end of the first section 311 enters / protrudes out of the window 111 at the top of the handle 1. In addition, one end of the second section 312 slides into / out of the limiting groove 23.

[0097] Specifically, when the interlocking structure 3 is along such Figure 6 When rotated clockwise in the direction Y, as shown, one end of the first segment 311 enters the window 111 located at the top of the handle 1, and the other end of the first segment 311 protrudes from the window 111 at the top of the handle 1. Additionally, one end of the second segment 312 slides out of the limiting groove 23. Correspondingly, when the interlocking structure 3 rotates clockwise as shown... Figure 6When rotated counterclockwise in the direction Z, one end of the first segment 311 protrudes from the window 111 provided at the top of the handle 1, and the other end of the first segment 311 enters the window 111 at the top of the handle 1. In addition, one end of the second segment 312 slides into the limiting groove 23.

[0098] Since the lock hole 35 is located at one end of the first section 311, the indicator 31 is located at the other end of the first section 311, the slider 32 is located at one end of the second section 312, and the second pin hole 33 is located at the other end of the second section 312, when the interlocking structure 3 rotates clockwise in the Y direction, the lock hole 35 enters the window 111, the indicator 31 protrudes from the window 111, and one end of the second section 312 slides out of the limiting groove 23, preventing the groove wall of the limiting groove 23 from contacting the slider 32, thereby allowing the interlocking structure 3 and the handle 1 to rotate along the first axis. In other words, the handle 1 is in the unlocked state at this time.

[0099] Correspondingly, when the interlocking structure 3 rotates counterclockwise in the Z direction, the lock hole 35 protrudes from the window 111, the indicator 31 enters the window 111, and one end of the second section 312 slides into the limiting groove 23, causing the slider 32 to abut against the groove wall of the limiting groove 23, thereby preventing the interlocking structure 3 and the handle 1 from rotating along the first axis. In other words, the handle 1 is in a locked state at this time.

[0100] In summary, when the keyhole 35 enters the window 111, it indicates that the handle 1 is in the unlocked state. When the latch protrudes from the window 111, it indicates that the handle 1 is in the locked state. Therefore, in some embodiments, an indicator for indicating the locked state of the handle 1, such as a lock-shaped pattern, can be provided at one end of the first segment 311, so that the operator can accurately determine the current state of the handle 1 by the relative position of the indicator and the window 111.

[0101] Furthermore, since the indicator 31 is the other end of the first segment 311, the interlocking structure 3 and the indicator 31 are integrated into one structure, which can prevent the indicator 31 from becoming loose or falling off, and enable the indicator 31 to accurately reflect the status of the circuit system, thereby improving the accuracy of the operator's judgment of the status of the circuit system and reducing the safety hazards existing in the circuit system.

[0102] According to the description of the above embodiments, the interlocking structure 3 is T-shaped, including a first section 311 and a second section 312. A lock hole 35 is located at one end of the first section 311, an indicator 31 is located at the other end of the first section 311, a slider 32 is located at one end of the second section 312, a second pin hole 33 is located at the other end of the second section 312, and one end of the through slot is a window 111 located at the top of the handle 1. This allows the operator to accurately determine whether the handle 1 is locked or unlocked by observing the relative position of the lock hole 35 and the window 111. Furthermore, since the indicator 31 is located at the other end of the first section 311, the interlocking structure 3 and the indicator 31 are integrated, preventing the indicator 31 from becoming loose or falling off. This ensures that the indicator 31 accurately reflects the status of the circuit system, thereby improving the operator's accuracy in judging the circuit system status and reducing potential safety hazards in the circuit system.

[0103] Specifically, in some embodiments, the first angle α is greater than or equal to 10°.

[0104] When the first angle α is too small, the lock hole 35 cannot be fully exposed, thus preventing the limiting component from being installed. Therefore, the first angle α is greater than or equal to 10° to ensure that the lock hole 35 is fully exposed, thereby allowing the limiting component to be installed smoothly, so as to achieve the function of restricting the handle 1 to the locked state through the interlocking structure 3.

[0105] According to the description of the above embodiment, the first angle α is greater than or equal to 10°, which can ensure that the lock hole 35 is fully exposed, so that the limiting member can be installed smoothly, so as to realize the function of restricting the handle 1 to the locked state through the interlocking structure 3.

[0106] Furthermore, in some embodiments, a reflective strip is affixed to the other end of the first segment 311.

[0107] Reflective strips are a type of safety device that primarily utilizes the principle of retroreflection, which means that light rays from a distance that strike the strip are reflected back to the source at a certain intensity along their original path. When light shines on a reflective strip, it undergoes a series of optical processes, such as refraction and reflection, ultimately causing the light to be reflected back in a direction nearly parallel to the incident light, thus producing light on the reflective strip and making it visible to the naked eye in low light conditions.

[0108] According to the description of the above embodiment, a reflective strip is attached to the other end of the first section 311 so that the operator can see the position of the first section 311, i.e. the indicator 31, in a dim environment, thereby accurately judging the status of the circuit system and reducing the safety hazards in the circuit system.

[0109] Furthermore, in some embodiments, one end of the first segment 311 is connected to an abutment portion 313. The abutment portion 313 extends along a first direction X and toward the base 2. A protrusion structure 314 is provided on the abutment portion 313. When the handle 1 is in the unlocked state, the abutment portion 313 abuts against the inner wall of the through groove. When the handle 1 is in the locked state, the distance between the protrusion structure 314 and the inner wall of the through groove is less than or equal to 0.5 mm.

[0110] When the interlocking structure 3 rotates along the second shaft, the first section 311 will rotate together. During the rotation, the distance between the first section 311 and the inner wall of the through groove will change, causing a gap between the handle 1 and the interlocking structure 3. This gap allows external impurities to enter the circuit system, thereby affecting the protection level of the circuit system.

[0111] Based on this, such as Figure 5 and Figure 6 As shown, one end of the first section 311 is connected to an abutment portion 313 extending toward the base 2. The protruding structure 314 provided on the abutment portion 313 can be used to reduce the gap between the handle 1 and the interlocking structure 3, thereby improving the protection level of the circuit system.

[0112] Specifically, when the handle 1 is in the unlocked state, the abutment part 313 abuts against the inner wall of the through groove. At this time, there is no gap between the handle 1 and the interlocking structure 3, which ensures the protection level of the circuit system.

[0113] When handle 1 is in the locked state, interlocking structure 3 rotates along the second pivot. During rotation, the first section 311 causes the abutment portion 313 to extend away from the inner wall of the through groove. At this time, the distance between the protrusion 314 on the abutment portion 313 and the inner wall of the through groove is less than or equal to 0.5 mm, preventing most impurities from entering the circuit system and thus improving the protection level of the circuit system.

[0114] According to the description of the above embodiments, the abutment portion 313 connected to one end of the first segment 311 and the abutment portion 313 are provided with a protruding structure 314, which is used to prevent most impurities from entering the circuit system when the handle 1 is in the unlocked state and the locked state, thereby improving the protection level of the circuit system. Secondly, this application provides a circuit system including the handle as described in any of the above embodiments, the handle being used to control the on / off state of current in the circuit system.
