Description

Technical Field

[0001] The invention belongs to the technical field of electrical equipment, and in particular to an interlocking device for a drawer of a switch cabinet drawer compartment. Background Art

[0002] The switch cabinet drawer compartment is an electrical device with drawers movably provided on the switch cabinet drawer compartment. Different circuit controllers are respectively provided in each drawer, so that the circuit can be controlled through the switch cabinet drawer compartment. At the same time, the switch cabinet drawer usually has three different special status positions, namely, the separation position, the test position and the connection position. The separation position is the position where the circuit is completely disconnected. In this position, the switch cabinet drawer compartment drawer can be pulled out to perform maintenance operations on the components and circuits in the drawer to avoid causing danger; in the test position, the circuit of the device is partially conductive and can be used as a test circuit, also called the test state. In this position, the drawer is not allowed to be pulled out; the connection position means that in this position state, the circuit is in a state where it can be fully connected and can operate normally after closing the switch. Working, also known as the working position, in this state, the drawer is in a locked state and is not allowed to be pulled out; therefore, it is necessary to design an interlocking device to ensure the locking of the drawer in these three states, but the existing drawers have a variety of models, such as 1 / 2 drawer size model, 1 / 4 drawer size model and full drawer size model. These different models of drawers also need to be installed with interlocking mechanisms of different structural forms. The structure of these interlocking mechanisms is complex, resulting in low production and processing efficiency and increased production costs. At the same time, in order to cooperate with the locking, a display mechanism needs to be designed to timely indicate the status and position of the drawer cabinet for the operator to observe. However, the existing display mechanism is prone to deviation due to the vibration of the switch cabinet when in use, which makes observation inconvenient and is not conducive to improving utilization efficiency. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the present invention provides a switch cabinet drawer that can ensure that the use requirements are met in three state positions. At the same time, the structure is simple, easy to process and produce, and the overall structure of the display mechanism is more stable.

[0004] The present invention provides a switch cabinet drawer, comprising a drawer compartment, in which a drawer is slidably arranged, an operating knob for controlling the on and off of components in the drawer is provided on the drawer panel, a mounting seat is provided in the drawer, an interlocking mechanism for limiting the sliding of the drawer as the operating knob rotates is provided on the mounting seat, and a display mechanism for displaying the state position of the drawer as the drawer moves is also provided on the mounting seat.

[0005] The beneficial effect of this arrangement is that, by adopting the above-mentioned scheme, the display mechanism is arranged to change the display form as the drawer moves, which is different from the traditional linkage by turning the knob, so that the display mechanism and the linkage mechanism are separated. This structure is simpler, easy to install and produce, and improves production and processing efficiency, while also effectively improving the stability of the structure.

[0006] The present invention is further provided with that the display mechanism includes a swing seat and a swing guide column, an arc-shaped slide groove is provided on the bottom surface of the drawer, the swing guide column is provided in the arc-shaped slide groove and extends outward of the drawer, the swing seat is rotatably provided on the mounting seat, a display board is provided on the swing seat, and a display window is provided on the drawer panel corresponding to the display board position, the swing guide column is connected to the swing seat through a connecting arm, and a positioning block is provided on the bottom surface of the drawer compartment for contacting the swing guide column when the drawer slides, and the swing guide column contacts the positioning block when the drawer slides to form a transmission for the swinging of the swing seat, and a reset torsion spring for resetting the swing guide column is also provided between the swing seat and the swing guide column.

[0007] The beneficial effect of such a setting is that: the display mechanism is set up in this way by adopting the above scheme. As is known, to achieve the three status positions of the switch cabinet, the drawer needs to be in three different positions, that is, when in the connected position, the drawer needs to be fully inserted into the drawer compartment. When in the test position, the drawer is mostly inserted into the drawer compartment but not fully inserted, and there is still a small displacement distance from the connected position. In the separated position, the drawer is in an area where it can be freely plugged and unplugged. When the drawer moves from the separated position to the test position, the drawer moves into the drawer compartment, and the swing guide post moves with the drawer and abuts against the positioning block. As the drawer goes deeper into the drawer compartment, the swing guide post slides along the arc-shaped slide groove due to the limiting effect of the positioning block, thereby driving the swing seat to rotate, and also causing the display board to rotate gradually, and the symbol indicating the test position on the display board is turned to the front to replace the original symbol indicating the separated position, and through the display The window is exposed for observers to observe. Of course, the size of the display window here is the same as the size of the symbol indicating the position status, so as to avoid displaying other symbols, which may cause users to misread and cause unnecessary trouble. When moving from the test position to the connected position, the steps are the same as the above steps. In the process of pulling the drawer out from the connected position, under the action of the reset torsion spring, the swing guide column moves along the arc-shaped slide groove, thereby gradually rotating the display card from the connected position to the test position, and finally to the separation position, realizing the marking display of the status position. With this structure, the display card changes with the movement of the drawer, which is different from the traditional linkage through the rotation of the knob. This structure is simpler and the transmission structure is easier to implement. At the same time, it is not easy for the display card to shake due to the vibration of the knob and other structures, maintaining the stability of the display card position, making it easier to observe and extending the service life of the display sign.

[0008] The present invention is further configured such that a cover is provided on the swing seat, an arc guide groove is provided on the cover corresponding to the position of the arc slide groove, one end of the swing guide column passes through the drawer, and the other end slides and cooperates with the arc guide groove.

[0009] The beneficial effect of this arrangement is that by adopting the above scheme, the protection sealing level of the entire equipment can be further improved through the cover structure, and at the same time, an arc guide groove is provided to guide the swing guide column, thereby further improving the stability of the overall structural movement. At the same time, the structure is simple and easy to implement.

[0010] The present invention is further configured such that a transparent cover is provided on the display window, positioning teeth are provided on both sides of the transparent cover, and the transparent cover is fixed in the display window by the positioning teeth.

[0011] The beneficial effect of such a setting is that: adopting the above solution, setting a transparent cover can prevent dust or pollutants from entering the drawer, thereby improving the protective sealing level of the drawer. At the same time, the structure is simple and easy to install.

[0013] The beneficial effect of such a setting is that, when the locking pin is aligned with the locking hole, the locking pin can be dropped into the locking hole by the locking spring. The setting of the locking spring here is that it is sleeved on the locking pin, and a positioning protrusion is provided on the locking pin. One end of the locking spring abuts against the inner wall of the mounting seat, and the other end abuts against the positioning protrusion, thereby realizing the locking pin is inserted into the locking hole, so that the drawer can be locked in two positions, limiting the sliding of the drawer. The switch cabinet is operated by the operating knob, and the operating knob extends a square shaft into the drawer compartment. The square shaft rotates synchronously with the operating knob. In the test position and the on position, the locking plate limits the locking pin from disengaging from the locking hole. There are many ways to lock the lock pin here, such as limiting the transmission rod The sliding method can also press the lock pin so that the lock pin cannot fall out. When unlocking or replacing the state is required, the operating knob is turned to the off-circuit position to ensure that the internal circuit is disconnected, so that the drawer can be pulled out, and the lock pin is unlocked by controlling the transmission rod through the push button. There are many ways to unlock here, such as pushing the transmission rod so that the inclined surface on the transmission rod contacts the lock pin, driving the lock pin to lift and leave the locking hole, or turning the push button to rotate the transmission rod, and the transmission rod and the lock pin are both set as threaded rods, and the two cooperate to control the lock pin to disengage or insert into the locking hole.

The beneficial effect of such arrangement is that, by adopting the above scheme, the display mechanism is arranged in this way. As is known, to achieve the three status positions of the switch cabinet, the drawer 2 needs to be in three different positions, that is, in the on position, the drawer 2 needs to be fully inserted into the drawer compartment 1. In the test position, the drawer 2 is mostly inserted into the drawer compartment 1 but not fully inserted, and there is still a small displacement distance from the on position. In the separated position, that is, the drawer 2 is in an area where it can be freely plugged and unplugged, when the drawer 2 moves from the separated position to the test position, the drawer 2 moves into the drawer compartment 1, and the swing guide post 61 moves with the drawer 2 and abuts against the positioning block 12. As the drawer 2 goes deeper into the drawer compartment 1, the swing guide post 61 slides along the arc-shaped slide groove 31 due to the limiting effect of the positioning block 12, thereby driving the swing seat 6 to rotate, and also causing the display board 63 to rotate gradually, and the symbol indicating the test position on the display board 63 is turned to the front to replace the original symbol indicating the separated position. And it is exposed through the display window for observers to observe. Of course, the size of the display window here is the same as the size of the symbol indicating the position status, so as to avoid displaying other symbols, causing users to misread and cause unnecessary trouble. When moving from the test position to the connected position, it is also the same as the above steps. In the process of pulling the drawer 2 out from the connected position, under the action of the reset torsion spring 64, the swing guide column 61 moves along the arc-shaped slide groove 31, thereby gradually rotating the display board 63, gradually turning from the connected position to the test position, and finally reaching the separation position to realize the marking display of the status position. With this structure, the display board 63 changes with the movement of the drawer 2. Unlike the traditional linkage by turning the knob, this structure is simpler and the transmission structure is easier to implement. At the same time, it is not easy for the display board 63 to shake due to the vibration of the knob and other structures, maintaining the stability of the position of the display board 63, making it more convenient to observe, and also extending the service life of the display sign.
