Description

Technical Field

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

[0002] The electrical cabinet is equipped with a switch handle, and the switch handle is turned to switch on and off. For personal safety, the electrical cabinet is required to be prohibited from closing when the staff is inspecting. Therefore, there is a state warning device that can be added to the cabinet body to achieve a warning effect on the switch handle. The state warning device includes a lock body fixedly installed on the cabinet body and a plug-in removable cover. The lock body is provided with a slot and the cover is provided with a tongue and an opening. When it is necessary to warn the staff not to close the switch, the cover can be inserted into the lock body, and the cover will cover the switch handle and limit its handle in the opening, so that the switch handle cannot be rotated.

[0003] The rotating switch handle has at least two positions. For the switch handles at different positions, different covers need to be installed respectively, so the number of covers required for the status warning device is two or even three. Since the covers are removed when the electrical cabinet is working normally, the more covers there are, the more likely it is that the storage and management will be difficult and the covers will be lost. Therefore, there is also an improved plug-in status warning device that provides a second lock tongue that can cooperate with the slot on the other side of the cover. In this way, even if the switch handle is rotated 90 degrees, the cover can still cooperate with the switch handle and its handle to achieve the function of limiting rotation and warning after being installed using the second lock tongue, thereby solving the problem of difficult storage and management due to the large number of covers.

[0004] However, even if the improved status warning device only needs to be equipped with one cover, the cover still needs to be disassembled and stored separately when the electrical cabinet is working normally, and the problem of easy loss cannot be avoided. Utility Model Content

[0005] The first purpose of the utility model is to provide a rotary state warning device which completely solves the problem of loss of the blocking cover after disassembly.

[0006] The second object of the utility model is to provide an electrical cabinet adopting the above-mentioned rotary status warning device.

[0007] The first object of the utility model provides a rotary status warning device, comprising a lock body and a blocking cover connected to each other, the blocking cover is provided with an opening for cooperating with the handle of the switch handle; a slide groove extending along an arc is provided on the lock body, and a side wall extending along the arc is provided on the blocking cover, the side wall and the slide groove are slidably matched, and the blocking cover can rotate around the axis between a first angle and a second angle, and the axis coincides with the rotation axis of the switch handle; the rotary status warning device also includes a control circuit, a first magnetic induction unit, a second magnetic induction unit and a lock tongue, the first magnetic induction unit and the second magnetic induction unit are both electrically connected to the control circuit, the control circuit is arranged in the lock body, and the first magnetic induction unit and the second magnetic induction unit are The sensing unit is arranged toward the slide slot, and the lock tongue is controllably telescopically mounted on the lock body and can be extended to the slide slot; the rotary status warning device also includes a first magnet and a second magnet, which are respectively mounted at different circumferential positions of the side wall, and a first plug hole and a second plug hole are also arranged on the side wall, which are respectively arranged at different circumferential positions of the side wall; when the blocking cover is at a first angle, the first magnet is within the sensing range of the first magnetic sensing unit, the lock tongue is inserted into the first plug hole and limits the rotation of the blocking cover; when the blocking cover is at a second angle, the second magnet is within the sensing range of the second magnetic sensing unit, the lock tongue is inserted into the second plug hole and limits the rotation of the blocking cover.

[0008] It can be seen from the above scheme that the utility model installs the cover on the lock body in a non-detachable and rotatable manner, and uses the signal obtained by electromagnetic induction to determine whether the cover is rotated into place and whether the cover is at the first angle or the second angle, and then uses the lock tongue to insert into the side plate to limit the rotation, thereby restricting the operation of the switch handle covered under the cover. When the switch handle is no longer needed to restrict, it is only necessary to unlock the lock body with a key or a computer key so that the lock tongue pops out, and the cover resumes its freedom of rotation, and can rotate with the switch handle. In this way, the status warning device can be installed on the electrical cabinet in a fixed and non-removable manner, which not only meets the restriction requirements of the two positions of the switch handle, but more importantly, it eliminates the tedious operations of cover removal, storage management and next-time search, and completely solves the problem of cover removal and loss.

[0009] A further solution is that the lock body includes an outer shell, a baffle, a bottom plate and a top plate, and the control circuit, the first magnetic induction unit, the second magnetic induction unit and the lock tongue outer shell are installed in the outer shell; the outer shell is located on the outer periphery of the slide slot, the baffle is located on the inner periphery of the slide slot, the bottom plate is connected between the outer shell and the baffle, the top plate is connected to the outer shell, and the top plate and the bottom plate are located on opposite sides of the axis of the slide slot in the axial direction; the outer shell and the baffle respectively limit the side walls from the radial sides of the axis, and the top plate and the bottom plate respectively limit the side walls from the axial sides of the axis.

[0010] As can be seen from the above, under this setting, except for the rotational freedom, the other movement freedoms of the cover are effectively restricted, which not only ensures smooth rotation but also solves the problem of loosening.

[0011] A further solution is that a communication port is formed between the top plate and the baffle plate; the baffle cover also includes a top wall, the side walls are connected to the edge of the top wall, and the top wall is located in the communication port.

[0012] As can be seen from the above, the side wall cooperates with the slide groove to enable the cover to rotate. The side wall is the key force-bearing part. The side wall is set along the edge of the top wall. The two have better bonding strength and can weaken the elastic deformation performance of the side wall, thereby making the side wall have better strength and extending the service life.

[0013] A further solution is that the surface of the top plate is provided with warning features, and the warning features include at least one of characters, patterns and colors.

[0014] As can be seen from the above, a better warning effect can be achieved by engraving warning words, warning symbols, warning patterns or warning colors such as red on the exposed conspicuous parts of the top plate.

[0015] Another further solution is that the outer shell includes a main shell and a bottom shell that are detachably connected, the main shell forms an installation space and an installation entrance of the installation space, the bottom shell blocks the installation entrance, and a connection structure for connecting to an electrical device is provided on the bottom shell; the bottom plate and the baffle are integrally formed on the bottom shell.

[0016] As can be seen from the above, this arrangement allows the limiting structures of the side walls to be separated. First, the bottom shell is fixed to the electrical cabinet, and after the side walls of the cover are buckled, the main shell is installed to form a complete lock body while also limiting the side walls. This can reduce the difficulty of installing the cover and is also more conducive to fixing the lock body to the main body of the electrical equipment.

[0017] In a further solution, the shell includes an inner side surface arranged toward the slide slot, the baffle includes an outer side surface arranged toward the slide slot, the inner side surface and the outer side surface are arranged opposite to each other, both the inner side surface and the outer side surface are arc surfaces and are concentric therebetween.

[0018] As can be seen from the above, this arrangement enables the formed slide groove to have a higher curvature, further ensuring smooth rotation of the cover.

[0019] A further solution is that the side wall includes an inner side facing the axis, and a first stop protrusion and a second stop protrusion are provided on the inner side, and the first stop protrusion and the second stop protrusion are respectively provided at different circumferential positions of the side wall; when the baffle cover is at a first angle, the first stop protrusion limits the baffle in front of the first rotation direction from the first angle to the second angle; when the baffle cover is at a second angle, the second stop protrusion limits the baffle in front of the second rotation direction from the second angle to the first angle.

[0020] As can be seen from the above, this setting can avoid over-travel and damage to the blocking cover, lock body and even the switch handle.

[0021] In another further solution, the side wall includes an inner side facing the axis, and a first mounting blind hole and a second mounting blind hole are provided on the inner side. The first magnet is mounted in the first mounting blind hole, and the second magnet is mounted in the second mounting blind hole.

[0022] It can be seen from the above that this arrangement can not only firmly fix the first magnet and the second magnet, but the side wall can also block external influences for the first magnet and the second magnet, ensuring that the magnetic attraction properties of the first magnet and the second magnet are effective for a long time.

[0023] In another further solution, the rotary status warning device further comprises a lock core arranged in the lock body, and the lock core is drivingly connected to the lock tongue.

[0024] The second purpose of the utility model provides an electrical cabinet comprising a cabinet body and a switch handle installed on the cabinet body, the switch handle can be rotated between a first position and a second position, and the electrical cabinet also comprises a status warning device installed at the switch handle; the status warning device adopts the above-mentioned rotary status warning device.

The first magnetic induction unit 31 and the second magnetic induction unit 32 are placed inside the housing 111 and are located at different circumferential positions of the axis. A matching hole 1101 is provided on the wall surface of the housing 111. The lock tongue 42 is movably provided along the x-axis direction and can extend into the slide slot 10 through the matching hole 1101.

[0039] See also Figure 3 and Figure 6The blocking cover 2 includes a top wall 21 and a side wall 22. The top wall 21 has an arc-shaped outer peripheral edge. The side wall 22 is connected to the edge of the top wall 21 and extends along the negative direction of the z-axis, so that the side wall 22 extends along the arc line. A hollow convex seat 23 is also formed on the top wall 21. One end of the convex seat 23 forms an opening 230 for matching with the handle 91 of the switch handle 9 along the radial direction of the axis. The space surrounded by the top wall 21 and the side wall 22 becomes the accommodating space of the handle, such as Figure 3 As shown, the axis of the blocking cover 2 coincides with the rotation axis 90 of the matching switch handle 9.

[0040] Continue to see Figure 6 First, the side wall 22 is also provided with a first plug hole 2201 and a second plug hole 2202, which are respectively arranged at different circumferential positions of the side wall 22. Then, the side wall 22 includes an inner side 229 facing the axis, which is provided with a first mounting seat 221 and a second mounting seat 222 at different circumferential positions of the side wall 22, a first mounting blind hole 2210 is arranged on the first mounting seat 221, and a second mounting blind hole 2220 is arranged on the second mounting seat 222, the first magnet 51 is installed in the first mounting blind hole 2210, and the second magnet 52 is installed in the second mounting blind hole 2220, so that the first magnet 51 and the second magnet 52 are respectively located at different circumferential positions of the side wall 22. In addition, the inner side 229 is provided with a first anti-rotation protrusion 223 and a second anti-rotation protrusion 224, which are ribs protruding from the surface of the inner side 229 and extending in the z-axis direction, and the first anti-rotation protrusion 223 and the second anti-rotation protrusion 224 are respectively arranged at different circumferential positions of the side wall 22. The two objects arranged at different circumferential positions of the side wall 22 have an angle with the axis of the blocking cover 2 as the center.

[0041] When installing the rotary status warning device, first fix the bottom shell 12 to the electrical cabinet, buckle the side wall 22 of the cover 2, and then install the main shell 11 to form a complete lock body 1 while restricting the side wall 22. At this time, the side wall 22 is restricted in the slide groove 10, and the side wall 22 and the slide groove 10 are slidably matched so that the cover 2 can rotate along the axis. In addition, at this time, the top wall 21 is located in the communication port 101.

[0042] See also Figure 1 and Figure 7 When the switch handle 9 of the first station is restricted, the cover 2 is at the first angle, the first magnet 51 is in the sensing range of the first magnetic sensing unit 31, the lock tongue 42 is inserted into the first jack 2201 and restricts the cover 2 from rotating.

[0043] See also Figure 2 and Figure 8When the switch handle 9 of the second station is restricted, the cover 2 is at the second angle, the second magnet 52 is in the sensing range of the second magnetic sensing unit 32, the lock tongue 42 is inserted into the second jack 2202 and restricts the cover 2 from rotating.

[0044] When the switch handle 9 does not need to be restricted, it can be unlocked by the computer key, the lock tongue 42 will retract into the housing 111 and unlock the side wall 22, the side wall 22 will restore the freedom to move along the arc, and the blocking cover 2 will restore the freedom to rotate and can rotate with the switch handle 9.

[0045] Mainly, the utility model installs the blocking cover 2 on the lock body 1 in a non-detachable and rotatable manner, and uses the signal obtained by electromagnetic induction to determine whether the blocking cover 2 is rotated to the right position and whether the blocking cover 2 is at the first angle or the second angle, and then uses the lock tongue 42 to insert into the side plate to limit the rotation, thereby limiting the switch handle 9 covered by the blocking cover 2. When the switch handle 9 is no longer needed to be restricted, the lock body 1 only needs to be unlocked by a key or a computer key so that the lock tongue 42 pops out, and the blocking cover 2 resumes free rotation, and can rotate together with the switch handle 9.

[0046] In this way, the status warning device is fixed and does not need to be disassembled, which meets the requirements of restricted operation and warning function of the two positions of the switch handle. More importantly, it eliminates the tedious operations of cover removal storage management and next time search, and completely solves the problem of loss of the cover after removal.

[0047] In addition, the utility model also requests protection for an electrical cabinet installed with the rotary status warning device of the utility model, the electrical cabinet comprising a cabinet body and a switch handle mounted on the cabinet body, the switch handle being rotatable between a first work position and a second work position, the electrical cabinet also comprising a status warning device mounted at the switch handle; the status warning device adopts the above-mentioned rotary status warning device.
