[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model.

[0032] Refer to Figure 1 and Figure 2 , the present utility model discloses a circuit breaker locking device, including a button base 10, a button 20 and an opening and closing member 30.

[0033] The button base 10 has a restored position and a starting position.

[0034] The button 20 is movably arranged in the button base 10, and the button 20 reciprocates on the path between the restored position and the starting position.

[0035] The opening and closing member 30 is arranged on one side of the path. The opening and closing member 30 enters the path to block the path, so as to prevent the button 20 located at the restored position from moving towards the starting position. The opening and closing member 30 exits the path to open the path, ensuring that the button 20 reciprocates on the path.

[0036] It can be understood that by pressing the button 20 in the button holder 10, the button 20 moves in the button holder 10. As previously mentioned, the button holder 10 has a reset position and a start position at different locations. It can be understood that the button 20 is used to disconnect in the reset position (the circuit breaker is in the open state) and is used to trigger in the start position (the circuit breaker is in the closed state). The path between the reset position and the start position constitutes the movement path of the button 20.

[0037] The button 20 can be selected to have a common square outer shape, a cylindrical outline or a circular shape. The shape of the button 20 can be selected according to needs and is not limited here. What is important is that the button 20 is movably set in the button seat 10. The way the two are movably connected includes but is not limited to the commonly used slider and slide rail method, which will not be repeated here.

[0038] According to the above, the button 20 reciprocates on the path to switch back and forth between the triggering and disconnecting states. As can be seen from this, the button base 10 provides a reliable activity path for the button 20, thereby improving the safety and reliability of the activity.

[0039] Optionally, the button seat 10 is a accommodating shell, and an accommodating cavity 11 is provided in the middle of the accommodating shell, with a reset position and a start position located in the accommodating cavity 11.

[0040] Among them, combined Figure 3 , the accommodating shell is selected to be a rectangular structure, and the rectangular accommodating cavity 11 with a restoration position and a start position is provided in the length direction of the rectangular accommodating cavity 11. It can be understood that one end of the accommodating cavity 11 is open, and the other end faces and side faces form a closed enclosure. The button 20 is loaded into the accommodating cavity 11 from the opening of the accommodating cavity 11 and moves in the accommodating cavity 11. In this embodiment, the accommodating cavity 11 forms an enclosing space, which effectively limits the button 20 in all directions, avoids the derailment of the button 20 to the greatest extent, and improves the reliability of its movement; in this embodiment, the restoration position is located at one end of the accommodating cavity 11 close to the opening of the accommodating cavity 11, and correspondingly, the start position is located at the other end of the accommodating cavity 11 relative to the restoration position.

[0041] Optionally, a flange 112 is provided extending outward from at least a portion of the edge of the accommodating shell at the opening of the accommodating cavity 11 , and the flange 112 is used to abut and position against the opening of the accommodating cavity 11 when the accommodating shell is installed at an external installation position.

[0042] Among them, as previously described, one end of the receiving cavity 11 is an open structure. Generally, the baffle 60 or other structures that can set external mounting positions can be used for mounting the button base 10. The external mounting position is adapted to the outer contour of the button base 10. For example, the external mounting position can be a chamber. In combination with this embodiment, the receiving shell is installed in the chamber. Therefore, in order to realize the installation and positioning of the receiving shell, a flange 112 is provided on at least part of the outer edge of the receiving shell at the opening position of the receiving cavity 11. The implementable ways of setting the flange 112 are: the flange 112 is provided on one edge or multiple edges of the opening of the receiving cavity 11.

[0043] After the receiving shell is installed in the chamber, one side of the flange 112 abuts against the outer wall of the chamber, so as to realize the installation and positioning of the receiving shell. At the same time, it is also convenient to take out the receiving shell 112 from the chamber by grasping the flange 112.

[0044] Optionally, the opening and closing member 30 is arranged outside the receiving cavity 11. An access opening 111 is provided on the side wall of the receiving cavity 11. The opening and closing member 30 enters or exits the receiving cavity 11 through the access opening 111 to block or open the path.

[0045] Among them, the opening and closing member 30 is arranged on one side of the path. The opening and closing member 30 can be optionally arranged in the receiving cavity 11 or hidden in the side wall of the receiving cavity 11. Of course, in order to solve the problem that it is inconvenient to install the opening and closing member 30 due to the limited internal space of the receiving cavity 11, in this embodiment, the opening and closing member 30 is arranged outside the receiving cavity 11. Therefore, in order to enable the opening and closing member 30 to enter the path of the receiving cavity 11, an access opening 111 is provided on the side wall of the receiving cavity 11. The access opening 111 communicates the inside and outside of the receiving cavity 11, and the opening and closing member 30 can enter and exit the receiving cavity 11 through the access opening 111.

[0046] Optionally, the receiving shell is provided with at least two latching protrusions 41 for latching and fixing with the grooves of the external mounting position.

[0047] Alternatively, the receiving shell is provided with at least two elastic arms that can elastically snap into the grooves of the external mounting position.

[0048] Among them, in order to realize the quick installation of the button base 10, at least two latching protrusions 41 are provided on the outer side of the button base 10. In combination with the foregoing embodiment of the receiving shell, the latching protrusions 41 are respectively installed on the outer sides of two opposite side walls of the receiving shell. Preferably, the latching protrusions are spherical protrusions or strip-shaped protrusions. Importantly, corresponding grooves for latching the latching protrusions 41 are provided on the corresponding inner walls of the external mounting position. When the button base 10 is installed in the mounting position, the latching protrusions are directly latched with the grooves, thereby realizing the quick installation of the button base 10 and improving the installation efficiency. The above-mentioned latching protrusions 41 can be selected as protrusion structures such as bumps and protrusions.

[0049] In addition, at least two elastic arms are provided on the outer side of the button base 10. The elastic arms can be common elastic structures such as elastic sheets with elastic deformation. Specifically, mounting holes are provided on the side wall of the receiving cavity 11. One end of the elastic arm is arranged on the side wall of the mounting hole, and the other end is a free end that protrudes from the outer wall of the receiving cavity 11. When the receiving shell is inserted into the mounting position, the free end is squeezed by the inner wall of the mounting position and contracts into the mounting hole. When the free end reaches the groove position, the free end snaps into the groove. When the free end exits the groove, it is also compressed and contracts into the mounting hole. In this way, the inward contraction of the free end reduces the friction between the free end and the inner wall of the mounting position when the button base 10 enters or exits the mounting position, facilitating the installation of the button base 10.

[0050] Optionally, in the direction perpendicular to the mounting direction of the button base 10, the clamping protrusion 41 is provided with a mounting inclined surface, and the mounting inclined surface is used for smooth abutment with the edge of the groove when the clamping protrusion 41 is inserted into or withdrawn from the groove.

[0051] Among them, the common structure of the clamping protrusion 41 is a polyhedral block protrusion. In order to enable the block protrusion to smoothly enter or exit the groove, it can be understood that in the direction perpendicular to the mounting direction of the button base 10, mounting inclined surfaces are provided on two opposite side surfaces of the block protrusion, and the mounting inclined surfaces gradually contract from the bottom to the top of the block protrusion. The mounting inclined surface provides a buffer surface for the block protrusion to enter the groove, avoiding edge collisions.

[0052] Optionally, the button 20 includes a pressing plate 21 and an abutting block 22.

[0053] The abutting block 22 is arranged on one side of the pressing plate 21, and when the button 20 is in the reset position and the opening and closing member 30 enters the path, the abutting block 22 in the reset position abuts against the opening and closing member 30.

[0054] Among them, the pressing plate 21 is a quadrilateral square plate adapted to the receiving cavity 11, and the number of the abutting blocks 22 is at least one. The abutting blocks 22 are arranged on one side of the pressing plate 20; in the embodiment with two abutting blocks 22, the two abutting blocks 22 are oppositely arranged at both ends of the same side of the pressing plate 21; in the embodiment with four abutting blocks 22, one abutting block 22 is arranged on each of the four edges of the same side of the pressing plate 21; when the pressing plate 21 is installed in the receiving cavity 11, the abutting block 22 and the pressing plate 21 enter in sequence, and finally the pressing plate 21 blocks the opening of the receiving cavity 11. During use, an external force is applied to the outer wall of the pressing plate 21 to enable the pressing plate 21 and the abutting block 22 to reciprocate in the receiving cavity 11. Combining the foregoing, the opening and closing member 30 enters or exits the receiving cavity 11 through the entrance and exit 111. In this embodiment, after the opening and closing member 30 enters the receiving cavity 11, if the button 20 wants to move from the reset position to the starting position at this time, the end of the abutting block 22 away from the pressing plate 21 abuts against the opening and closing member 30, thus blocking the movement of the button 20.

[0055] Optionally, it further includes an elastic member 50 disposed in the accommodation cavity 11. One end of the elastic member 50 acts on the pressing plate 21, and the other end acts on the inner wall of the accommodation cavity 11.

[0056] Under the action of an external force, when the pressing plate 21 moves from the self-restoring position to the starting position, the elastic member is compressed. When the action of the external force is withdrawn, the elastic member 50 rebounds to push the pressing plate 21 located at the starting position back to the self-restoring position.

[0057] It can be understood that the reciprocating movement of the pressing plate 21 between the self-restoring position and the starting position is driven by an external force. However, when the pressing plate 21 is at the starting position, it is close to the bottom of the accommodation cavity 11. Therefore, it is not easy to operate the pressing plate 21 to move from the starting position to the self-restoring position at this time. In this embodiment, an elastic member 50 is provided between the pressing plate 21 and the bottom of the accommodation cavity 11. Under the action of an external force, when the pressing plate 21 moves from the self-restoring position to the starting position, the elastic member is compressed. When the action of the external force is withdrawn, the elastic member 50 rebounds to push the pressing plate 21 located at the starting position back to the self-restoring position. It can be seen that the elastic member 50 can realize the automatic return of the pressing plate 21 from the starting position to the self-restoring position, solving the problem that it is inconvenient for the pressing plate 21 to return from the starting position to the self-restoring position as described above.

[0058] For example, the elastic member 50 is but not limited to structures or components with elastic deformation properties such as springs and elastic sheets.

[0059] Optionally, the elastic member 50 is a spring.

[0060] The button 20 further includes a positioning post 23 and a limiting member 24. One end of the positioning post 23 is connected to the pressing plate 21, and the other end passes through the spring and penetrates from the inside to the outside of the bottom wall of the accommodation cavity 11. The limiting member 24 is disposed at one end of the positioning post 23 penetrating the side wall of the accommodation cavity 11 and is configured outside the accommodation shell.

[0061] Among them, the positioning post 23 is preferably a cylindrical structure. The positioning post 23 and the abutting block 22 are arranged on the same side of the pressing plate. One end of the positioning post 23 is connected to the pressing plate 21, and the other end passes through the middle of the spring arranged in the accommodation cavity 11 and finally penetrates the bottom of the accommodation cavity 11 to reach outside the bottom wall. It should be noted here that the positioning post 23 and the bottom wall of the accommodation cavity 11 are in clearance fit. In addition, the limiting member 24 is arranged at one end of the positioning post 23 outside the bottom wall of the accommodation cavity 11, or it can be understood that the limiting member 24 and the elastic member 50 are respectively arranged outside and inside the accommodation cavity 11. Optionally, the limiting member 24 is a positioning pin, and a positioning hole is provided at the end of the positioning post 23. The positioning pin is inserted into the positioning hole to realize the quick connection between the limiting member 24 and the positioning post 23.

[0062] As described above, the positioning post 23 provides central support and limitation for the spring, preventing displacement of the spring during compression and restoration. Additionally, the limiting member 24 limits one end of the positioning post 23 outside the receiving cavity 11, preventing this end of the positioning post 23 from retracting into the receiving cavity 11 under the action of the elastic member 50.

[0063] Optionally, the opening and closing member 30 is a latching electromagnet. The latching electromagnet includes a base 31 and an iron core 32 that is telescopically disposed on the base 31. The iron core 32 can extend to enter and block the path, and the iron core 32 can contract to withdraw and open the path.

[0064] Among them, the latching electromagnet is a prior art. It should be noted here that the iron core 32 is telescopically disposed on the base 31, and the iron core 32 is used to enter or withdraw from the aforementioned path to achieve path blocking or opening. Additionally, the opening and closing member 30 can also be selected as a hydraulic cylinder or a pneumatic cylinder.

[0065] Before the installation of the circuit breaker latching device, according to the above, the button 20 and the elastic member 50 have been installed in the button seat 10, and the limiting member 24 also limits the positioning post 23 of the button 20; an adaptable installation position is provided on the baffle 60 (the thickness of the baffle 60 is less than the depth of the receiving cavity 11). When installing the circuit breaker latching device, the button seat 10 is horizontally inserted into the installation position. When the button seat 10 is installed in place, at this time, the clamping protrusion 41 is clamped in the groove on the inner wall of the installation position, and the flange 112 abuts against the end of the installation position; in this embodiment, after the button seat 10 is installed, the entrance and exit 111 is provided. In this way, the opening and closing member 30 is arranged above the button seat 10 and is vertically corresponding to the entrance and exit 111.

[0066] In addition, the logic of the entering or exiting path of the latching electromagnet is: the iron core 32 of the latching electromagnet can expand and contract with the power supply. It can be known that the latching electromagnet is connected in linkage with the external circuit. When the latching electromagnet of the present application is in a power-off state, the iron core 32 extends and enters the path to block when the button 20 is pressed (closed). On the contrary, when the latching electromagnet is in a powered-on state, the iron core 32 contracts and moves out of the path. At this time, the button 20 can be pressed for closing operation.

[0067] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches are also regarded as the protection scope of the present utility model.
