Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment accessories, in particular to an electrical switch state warning device and an electrical cabinet. Background Art

[0002] The cabinet body of the electrical cabinet is equipped with a rotating switch handle, and the switch handle is twisted to switch on and off. However, for personal safety, the electrical cabinet is required to prohibit closing when the staff is inspecting. Therefore, there is an existing electrical switch status warning device for adding between the cabinet body and the rotating switch handle to achieve status and warning effects. The electrical switch status warning device includes a lock body installed on the cabinet body and a detachable and pluggable cover. The lock body is provided with a slot, and a tongue is provided on one side of the length direction of the cover, and a handle for limiting the rotation of the handle and an opening for the handle to extend on the other side. In this way, when it is necessary to warn the staff to prohibit closing the switch, the cover can be inserted into the lock body. When the tongue is fully inserted into the slot, the cover will block the rotating handle from the front of the rotating shaft of the rotating handle, and the handle is limited in the opening and extends out of the cover from the opening. Since the cover is immovable, the staff cannot operate the rotating handle blocked and restricted by the cover.

[0003] The existing electrical switch status warning device, once installed on the cabinet, can only warn the state of the rotary handle when it is closed. However, in fact, in some maintenance scenarios, the electrical cabinet is also required to be kept in the closed state and the switch operation is prohibited. At this time, the opening position of the cover does not match the rotary handle in the closed state and cannot be used. Alternatively, a second cover with a different opening position needs to be configured, and different covers can be selected for installation according to different needs; but the cover itself is a detachable part that needs to be stored separately after use. The cover itself is easy to lose, and configuring multiple covers will make it more difficult to store them properly. Utility Model Content

[0004] The first object of the utility model is to provide an electrical switch state warning device capable of realizing a double-station state.

[0005] The second purpose of the utility model is to provide an electrical cabinet that can achieve a double-station state to meet more usage scenarios.

[0006] The first object of the utility model provides an electrical switch state warning device comprising a lock body and a blocking cover detachably mounted on the lock body, a slot being arranged on the lock body, the blocking cover comprising first plugging tongues and openings respectively arranged on opposite sides of the first direction of the blocking cover, a handle position being arranged between the first plugging tongue and the opening, the blocking cover being detachably connected to the lock body, in a first state, the first plugging tongue cooperates with the slot; the blocking cover further comprises a second plugging tongue arranged on one side of the second direction of the blocking cover, the second plugging tongue is located at the periphery of the handle position, and the second direction forms an angle with the first direction in the circumferential direction of the center of the handle position, and the insertion direction of the second plugging tongue is the same as the insertion direction of the first plugging tongue; the electrical switch state warning device can be changed to a second state, in the second state, the first plugging tongue is idle and the second plugging tongue cooperates with the slot.

[0007] It can be seen from the above scheme that, mainly, the utility model improves the original baffle cover so that it can be inserted into the lock body at two different angles, so that the opening direction of the baffle cover in different states is different and can be restricted and cooperated with handles in different directions. Therefore, the baffle cover can not only realize the warning reminder of "no closing the switch", but also realize the warning reminder of "no opening the switch". Without the need to add an additional baffle cover, it can be used with handles in two different work positions.

[0008] A further solution is that the blocking cover includes a top wall that blocks the handle position from the front in the insertion direction and a peripheral wall connected to the outer peripheral edge of the top wall; two first notches are provided on the peripheral wall to form a first insertion tongue between the two first notches; two second notches are provided on the peripheral wall to form a second insertion tongue between the two second notches.

[0009] Another further solution is that the outer peripheral contour of the peripheral wall is square, the first direction and the second direction are perpendicular to each other, and the first inserting tongue and the second inserting tongue are respectively formed on two mutually perpendicular side walls of the peripheral wall.

[0010] A further solution is that under this setting, the blocking cover has a better covering effect. While the blocking cover blocks and restricts the handle, the surrounding wall can still contact the surface of the cabinet body, and the surrounding wall can also produce abutment, positioning and supporting effects with the lock body. This setting makes the covering of the blocking cover more firm and reliable, avoiding the problem of loosening and falling.

[0011] A further solution is that the first inserting tongue and the second inserting tongue are in a plate shape, and the inner contour of the slot is in a straight line shape.

[0012] As can be seen from the above, this arrangement enables the cooperation between the tongue and the slot to effectively limit the deflection of the cover, further improving the cooperation stability.

[0013] A further solution is that the first plug tongue includes a first front end in the insertion direction, and the first front end is provided with a first convex portion with reduced width; the second plug tongue includes a second front end in the insertion direction, and the second front end is provided with a second convex portion with reduced width; a bayonet is provided at the bottom of the slot; in the first state, the first convex portion cooperates with the bayonet; in the second state, the second convex portion cooperates with the bayonet.

[0014] As can be seen from the above, this setting can control the insertion depth of the tongue and thus control the height of the cover, and the convex portion and the bayonet cooperate to achieve a certain locking effect, thereby making the cover and the lock body more firmly inserted and further avoiding the problem of loosening and falling.

[0015] Another further solution is that the blocking cover includes a first reinforcing rib connected between the top wall and the first plug tongue, and the blocking cover includes a second reinforcing rib connected between the top wall and the second plug tongue; the lock body includes a groove wall surrounding the slot, and the groove wall is provided with an avoidance opening on the entrance side of the slot; in the first state, the first reinforcing rib cooperates with the avoidance opening; in the second state, the second reinforcing rib cooperates with the avoidance opening.

[0016] As can be seen from the above, since the insertion direction is generally horizontal, the insertion tongue may need to bear the bending moment and torque caused by the gravity of the cover. The purpose of setting the reinforcing ribs is to improve the structural strength of the insertion tongue and the top wall, and the avoidance mouth avoids interference to ensure smooth insertion.

[0017] In addition, a further solution is that the electrical switch state warning device also includes a warning component and a reset component, the warning component includes a first side and a second side facing different directions, and corresponding warning features are respectively arranged on the first side and the second side; the warning component is rotatably mounted on the top wall, and the reset component is connected between the warning component and the baffle cover, and the warning component is kept in the first position under the action of the reset component, and when the warning component is in the first position, the first side is exposed to the baffle cover; a push rod is arranged on the lock body, and the warning component is provided with a driven part located at its own circumferential position, and during the process that the baffle cover cooperates with the lock body to the first state along the insertion direction, the push rod cooperates with the driven part and forces the warning component to rotate from the first position to the second position; in the first state, the warning component is in the second position, and the second side is exposed to the baffle cover; in the second state, the warning component is in the first position.

[0018] As can be seen from the above, in addition to the locking function, the cover also needs to achieve a warning function. Generally, it can be considered to print or engrave a warning message of "No Closing" on the surface of the top wall of the cover. However, the utility model involves a double station, and there is a demand for "No Opening" in the scene. "No Closing" will be misleading. For this reason, the utility model is also provided with a rotatable warning component. In different installation states, the warning component will be exposed on the first side or the second side respectively, and opposite warning features are respectively provided on the first side and the second side, such as "No Closing" and "No Opening". This setting achieves an accurate warning effect and further ensures the personal safety of the staff.

[0019] A further solution is that the warning component includes a cylinder arranged at its own axis, and the first side and the second side are both surfaces of the cylinder; the warning component also includes a rocker rod, which extends from the outer periphery of the cylinder in a direction away from the axis of the warning component, and the rocker rod serves as a driven part.

[0020] As can be seen from the above, this arrangement allows the rotating warning component to occupy a smaller space and does not affect the basic functions of the cover, such as shielding and limiting.

[0021] In another further solution, the warning feature includes at least one of characters, patterns and colors.

[0022] The second purpose of the utility model provides an electrical cabinet including a cabinet body and a switch handle installed on the cabinet body for realizing switching between opening and closing, the switch handle can rotate around its own axis between the opening position and the closing position, and the electrical cabinet also includes an electrical switch status warning device installed at the switch handle; the electrical switch status warning device adopts the above-mentioned electrical switch status warning device; the electrical switch status warning device in the first state cooperates with the switch handle in the opening position; the electrical switch status warning device in the second state cooperates with the switch handle in the closing position.

[0023] It can be seen from the above scheme that the utility model improves the original blocking cover so that it can be inserted into the lock body at two different angles, so that the opening direction of the blocking cover in different states is different and can be restricted and cooperated with handles in different directions. Therefore, the blocking cover can not only realize the warning reminder of "no closing the switch", but also realize the warning reminder of "no opening the switch". Without the need to add an additional blocking cover, it can be used with handles in two different work positions. BRIEF DESCRIPTION OF THE DRAWINGS
