Description

Technical Field

[0001] The present invention relates to the field of electrical and mechatronic technologies, and particularly to a mechanism for linking the open state of an equipment storage device with an electrical switch. Background Art

[0002] Electrical or mechatronic equipment usually needs to be protected, so it needs to be placed in equipment storage devices such as boxes, cabinets, and shells. Since regular inspections, maintenance, or repairs are required during faults, these boxes, cabinets, and shells all have structures such as doors or lids that can be opened to provide access for observation, maintenance, and repair. To ensure safety, some equipment requires that all internal power supplies or partial power supplies be disconnected when the door or lid is opened, or to provide observation lighting, it is required that the lighting circuit be connected when the door or lid is opened. Various application scenarios are summarized as the open state of the equipment storage device needs to be linked with the electrical switch.

[0003] Existing solutions mostly use rotatable mechanical parts (referred to as locking hooks for short) installed on boxes, cabinets, and shells to hook mechanical parts (referred to as pin shafts for short) fixed on the door or lid, link the locking hook with the electrical switch, and use the locking hook to control the connection or disconnection of the electrical switch.

[0004] During the repair or inspection process, it may be necessary to change the state of the linked electrical switch, that is, it is necessary to change the position state of the locking hook. After that, when closing the door or lid of the equipment storage device, if the position state of the locking hook is not corresponding to the open state, it is possible to damage the locking hook or the pin shaft, resulting in the failure of the linkage between the open state of the box, cabinet, and shell and the electrical switch. Summary of the Invention

[0005] Based on the defects existing in the above-mentioned prior art, the present invention provides a mechanism for linking the open state of an equipment storage device with an electrical switch, which solves the existing problems.

[0006] The present invention adopts the following technical solutions:

[0007] The present invention provides a mechanism for linking the open state of an equipment storage device with an electrical switch, the equipment storage device being a box, cabinet, or shell, inside which an electrical switch is installed.

[0009] A locking hook, arranged inside the box, cabinet, or shell, with one end fixed to the inner end of the switch shaft;

[0010] The hook head is installed at the other end of the locking hook through a hook head rotating shaft, and the hook head rotates through a limited angle around the hook head rotating shaft;

[0011] The spring is installed between the locking hook and the hook head, and the spring generates elastic force or releases elastic force when the locking hook and the hook head rotate relative to each other;

[0012] The lock pin is fixed on the inner side of the door or lid of the box, case, cabinet and shell, and its rotation axis is parallel or perpendicular to the rotation axis of the hook head;

[0013] The switch block is fixed on the locking hook and controls the electrical switch to be turned on or off during the rotation of the locking hook.

[0014] Preferably, the switch shaft is a key switch, which is rotated by a matching key. The rotating body is fixed with the locking hook. The key switch itself has a contact switch, which replaces the electrical switch or is connected in series with the electrical switch.

[0015] Preferably, the hook head is in a block shape, with a hole at one end. The hook head rotating shaft passes through the hole and rotates around the axis of the hole. The surface in contact with the locking hook has a sector-shaped groove, and the surface of the locking hook in contact with the hook head has a convex platform. The convex platform is located in the sector-shaped groove of the hook head, and the spring is located in the sector-shaped groove.

[0016] Preferably, the spring is a torsion spring. The torsion spring is sleeved on the hook head rotating shaft. One torsion arm is stuck on the wall surface of the sector-shaped groove, and the other torsion arm is stuck on the side surface of the convex platform.

[0020] The present invention is provided with a hook head at the end of the locking hook, which can rotate at a limited angle. The hook head limits the locking pin on the inner side of the door or lid of a box, a case, a cabinet, and a shell. This structure enables the door or lid of the box, the case, the cabinet, and the shell not to be opened randomly after being closed and hooked by the hook head. The door or lid of the box, the case, the cabinet, and the shell can be opened only after the switch shaft is rotated from the locked position to the free position. During the process of rotating the switch shaft, the electrical switch installed inside the box, the case, the cabinet, and the shell is controlled to disconnect or connect according to regulations. After the switch shaft is rotated to the locked position, even if the position state of the locking hook is not corresponded to the open door state by mistake, since the hook head can rotate, it will not prevent the closing of the door or lid, there will be no problem of damage to parts due to improper use, and there will be no problem of linkage failure between the open state of the box, the case, the cabinet, and the shell and the electrical switch.

Specific implementation mode

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] Referring Figure 1 , the present invention provides a mechanism for the linkage between the open state of a device storage device and an electrical switch, specifically relating to a mechanism for the linkage between the open state of a box, a case, a cabinet, and a shell and a split electrical switch, which is used to disconnect the electrical switch when the box, the case, the cabinet, and the shell are in the open state. The open-cover power-off device includes a switch shaft 1-1, a locking hook 1-2, and a hook head 1-3. The switch shaft 1-1 can rotate a certain angle. The switch shaft 1-1 penetrates the machine housing 5-2 and the locking hook 1-2 from the outside to the inside, and is then fastened with a locking hook fastener 1-9 to fix the locking hook to the switch shaft. At this time, the locking hook 1-2 can swing a certain angle following the rotation of the switch shaft 1-1. The hook head 1-3 is rotatably arranged on one side of the top end of the locking hook 1-2 through a movable assembly. A switch block 1-10 is fixedly arranged on the locking hook 1-2. A moving contact 1-14 is fixed on the switch block. When the moving contact 1-14 contacts the static contact 1-13, the safety switch is closed. When the switch shaft 1-1 rotates in a certain direction, the originally connected moving and static contacts can be disconnected, so as to achieve the purpose of power-off inside the machine. After the power-off inside the machine, the cover can be opened for operation, which can effectively protect the safety of personnel. On the basis of this function, considering the existence of abnormal operation procedures, such as after maintenance, the maintenance personnel first rotate the switch shaft 1-1 to the locked position and then close the machine cover 5-1. Therefore, a function of preventing the cover-closing action from damaging the open-cover power-off mechanism is added. A mechanism for the linkage between the open state of a device storage device and an electrical switch of the present invention includes an open-cover power-off device and a lock pin module of the machine cover 5-1. An electrical switch is installed inside the device storage device. The electrical switch is normally connected. After the cover of the device storage device is opened, the electrical switch needs to be disconnected, or the electrical switch is normally disconnected. After the cover of the device storage device is opened, the electrical switch needs to be connected.

[0041] Further, the hood 5-1 locking pin module consists of a locking pin 2-1 and a locking pin fastener 2-2. The locking pin cooperates with the hook head to control whether the hood 5-1 can be opened. The locking pin 2-1 is disposed through the side wall of the hood 5-1 of the equipment storage device, extending from the outside to the inside of the hood 5-1, and is locked and fixed to the side wall of the hood 5-1 through the locking pin fastener 2-2. After the lid is closed, the part of the locking pin 2-1 inside the hood 5-1 is hooked by the hook head 1-3 of the power-off device when opening the lid. At this time, the hood 5-1 will be restricted from opening. During the opening and closing process of the hood 5-1, there is no potential for movement interference with other components except for interference with the hook head 1-3 of the power-off device when opening the lid; it can be ensured that only when the hood 5-1 is closed, the switch shaft 1-1 is rotated by a certain angle first to disengage the hook head 1-3 from the pin shaft 2-1, and then the hood 5-1 can be smoothly opened.

[0042] Referring to Figure 2 , the end of the switch shaft 1-1 exposed outside the equipment storage device has a hand-operating and limiting structure. The upper locking buckle 4-1 is installed on the side wall of the housing of the equipment storage device through the upper locking buckle fixing shaft. The upper locking buckle 4-1 can rotate by a certain angle, and it is not limited whether it rotates with the shaft or around the shaft. When the switch shaft 1-1 is in the locked position, rotating the upper locking buckle 4-1 presses on the hand-operating structure of the switch shaft 1-1, and locking and connecting the hand-operating structure of the upper locking buckle 4-1 and the switch shaft 1-1 can keep the switch shaft 1-1 in the locked position to prevent its position from changing. Opening and removing the lock, rotating the upper locking buckle 4-1 to make it leave the hand-operating structure of the switch shaft 1-1, and the switch shaft 1-1 can be turned to the free position.

[0043] Referring to Figure 3 , the hook head 1-3 is rotatably arranged at one side of the top end of the locking hook 1-2 through a movable component. When the switch shaft is in the free position, the electrical switch is disconnected, and the hook head 1-3 rotates with the locking hook 1-2 to a position where it does not restrict the movement of the locking pin. Whether the hood 5-1 is opened or closed is not affected by the hook head. When the switch shaft rotates to the locked position, the electrical switch is connected, and the hook head 1-3 rotates with the locking hook 1-2 to a position where it restricts the movement of the locking pin, and the locking pin is blocked by the hook head, so the hood 5-1 cannot be opened.

[0044] Further, as Figure 4 shown, another installation position schematic diagram of the linkage between the equipment storage device and the split-type electrical switch in the present invention; the switch block 1-10 can be installed at different positions of the locking hook 1-2, rotates with the switch shaft 1-1, and is connected or disconnected from the static contact to control the on-off of the internal circuit of the machine. When the switch shaft is in the locked position, the electrical switch is disconnected, and the hook head restricts the movement of the locking pin. When the switch shaft is in the free position, the electrical switch is connected, and the hook head does not restrict the movement of the locking pin.

[0045] Further, as Figure 5 , (a) of Figure 5As shown in (b), the switch shaft 1-1 is a key switch which is rotated with a matching key. A locking hook 1-2 is fixed on its rotating body. Further, the key switch itself has a contact switch, which can replace an electrical switch or be connected in series with an electrical switch.

[0046] Further, as Figure 6 and Figure 7 shown, the split electrical switch is replaced with an integral electrical switch 1-5 that operates by contact movement. During the movement of the switch block 1-10 along with the switch shaft or the locking hook, the movement of the contact is controlled to disconnect or connect the integral electrical switch 1-5. Figure 6 When the hook head restricts the movement of the pin shaft, the switch block touches the contact. Figure 7 When the hook head does not restrict the movement of the pin shaft, the switch block releases the contact. Further, the relationship between the release or touch of the contact by the switch block and the restriction or non-restriction of the pin shaft movement by the hook head can be Figure 6 Figure 7 opposite to that shown. Further, the integral electrical switch can be normally open or normally closed. Further, the integral electrical switch can have both normally open and normally closed contacts simultaneously.

[0047] The present invention is not limited to the linkage form between the on-off state of the electrical switch and the open state of the equipment storage device. The integral contact can be selected as a normally open contact or a normally closed contact to meet the requirements of circuit on-off control. Finally, the open state of the equipment storage device is associated with the on or off state of the electrical switch.

[0048] Further, Figure 8As shown, the hook head 1-3 and the locking hook 1-2 are connected by a spring 1-4, a hook head rotating shaft 1-6 and a hook head fastener 1-7 to form a relatively rotatable structure. The hook head rotating shaft 1-6 penetrates through the locking hook 1-2 and the hook head 1-3, and the two are fixed by the hook fastener 1-7. A spring 1-4 is provided between the hook head 1-3 and the locking hook 1-2. There is a fan-shaped groove 1-11 on the hook head 1-2, and the spring 1-4 is installed in the fan-shaped groove 1-11. The locking hook 1-2 has a boss 1-12. One arm of the spring is stuck on the boss 1-12, and the other arm is stuck on the edge of the fan-shaped groove 1-11. This enables the hook head 1-3 to have a certain rotation angle. When the hook head 1-3 is not subject to external force, the torque generated by the torsion spring causes the hook head 1-3 to rotate until the wall surface of the fan-shaped groove 1-11 is closely attached to the boss 1-12 of the locking hook 1-2. When the door or lid of the box, box, cabinet or shell is closed and the switch shaft 1-1 is in the locked position, when directly opening the door or lid, the pin shaft pushes the rotation direction of the hook head so that the wall surface of the fan-shaped groove 1-11 is continuously closely attached to the boss 1-12 of the locking hook, and the hook head is mechanically blocked and cannot rotate, and the door or lid of the box, box, cabinet or shell cannot be opened. When the door or lid of the box, box, cabinet or shell is opened and the switch shaft is in the locked position, when closing the door or lid, the pin shaft pushes the rotation direction of the hook head so that the wall surface of the fan-shaped groove 1-11 continuously moves away from the boss of the locking hook. The hook head rotates and twists the torsion spring until the pin shaft and the hook head are disengaged, and the hook head rotates under the action of the torsion spring torque until the wall surface of the fan-shaped groove 1-11 is closely attached to the boss of the locking hook 1-2.

[0049] Further, referring to Figure 9 , the spring 1-4 is a torsion spring, the torsion spring is sleeved on the hook head rotating shaft 1-6, one torsion arm is stuck on the wall surface of the fan-shaped groove 1-11 of the hook head, and the other torsion arm is stuck on the side of the boss 1-12 of the locking hook. Referring to Figure 9 , the hook head 1-3 is block-shaped, there is a hole at one end, the hook head rotating shaft 1-6 passes through the hole and rotates around the axis of the hole. The surface in contact with the locking hook 1-2 has a boss 1-12. The surface of the locking hook 1-2 in contact with the hook head 1-3 has a fan-shaped groove 1-11. The boss 1-12 is located in the fan-shaped groove 1-11, and the spring 1-4 is located in the fan-shaped groove 1-11.

[0050] Further, the electrical switch is composed of a static contact point and an independent moving contact point, and is a split structure. When the moving contact point moves to an appropriate position, the electrical switch is turned on, and when it moves away to an appropriate position, the electrical switch is turned off. During the rotation of the switch block 1-10 with the locking hook 1-2, the electrical switch is controlled to be turned on or off. The moving contact point of the electrical switch is fixed on the switch block 1-10 and moves with the switch block 1-10 to turn on or off the electrical switch.

[0051] Further, the electrical switch is of an integral structure and includes a static contact and a moving contact inside. The mechanism controlling the movement of the moving contact extends a contact outside the electrical switch, and the position of the contact is controlled to turn on or off the electrical switch. During the rotation of the switch block with the locking hook 1-2, the on or off of the electrical switch is controlled by the switch block touching or releasing the contact to generate a certain stroke, and then the contact controls the on or off of the electrical switch.

[0052] The present invention is not limited to the displayed rotation angle, and the initial position and the rotatable angle can be set at any angle according to actual needs.

[0053] Further, Figure 10 It is a schematic diagram of the position of the hook head for preventing accidental closing of the cover. The radius of the locking pin 2-1 is R1, the radius of the arc at the upper end of the locking hook 1-2 is R2, and the movement radius of the locking pin 2-1 when the machine cover 5-1 is closed is R3. The relationship among R1, R2, and R3 is: R3 = R2 + R1 + reserved play clearance Y (Y > 0 mm).

[0054] The hook head 1-3 uses the hook head rotating shaft 1-6 as the rotation axis and is connected to the locking hook 1-2 by a fastener. A spring is arranged inside and can swing a certain angle. When the switch shaft is in the locked position, the position of the hook head 1-3 interferes with the locking pin 2-1 during the cover closing action. To prevent the locking pin from damaging the hook head when closing the cover in this case, the function of preventing accidental closing of the hook head is added to avoid damaging the opening and power-off mechanism. During the closing process of the machine cover 5-1, the locking pin 2-1 on the machine cover 5-1 can apply pressure to the outer contour surface of the hook head 1-3 after contacting the hook head 1-3. The spring inside the hook head 1-3 is compressed, and the hook head 1-3 rotates with the extrusion of the position of the locking pin 2-1. After the hook head 1-3 rotates a certain angle, the displacement of the locking pin 2-1 is greater than the outer contour length of the hook head 1-3, and the hook head 1-3 uses the spring to reset. The hook head 1-3 can be smoothly lifted at the moment of separating from the locking pin 2-1 of the machine cover 5-1, and there is no dead point position. At this time, the machine cover 5-1 will be restricted and cannot be opened.

[0055] The working principle of the present invention is as follows:

[0056] The rotation of the switch shaft 1-1 is restricted and can only rotate within a certain range. It is usually in one of two extreme positions. One restricted position is called the locked position, as shown in Figure 2 (a) of, and the other restricted position is called the free position, as shown in Figure 2 (b) of. When the switch shaft 1-1 is in the locked position, it can be mechanically locked and cannot be rotated arbitrarily, and can only be rotated when the mechanical lock is released.

[0057] When the door or lid of a box, case, cabinet, or housing is closed, after rotating the switch shaft 1-1 from the free position to the locked position, the hook head 1-3 will restrict the pin shaft from moving in the direction of door or lid opening, preventing the door or lid from being opened. Only when the locking of the switch shaft 1-1 is released and the switch shaft 1-1 is rotated to the free position, the pin shaft is no longer restricted by the hook head and can rotate in the opening direction of the door or lid. Regardless of whether the door or lid is closed or not, the switch shaft can be rotated unrestrictedly from the free position to the locked position. If the door or lid is already closed, after the switch shaft is rotated from the free position to the locked position, the hook head rotates with the switch shaft to the movement path of the pin shaft when the door or lid opens, blocking the pin shaft from moving in the opening direction of the door or lid. If the door or lid is not closed after the switch shaft is rotated from the free position to the locked position, and then the door or lid is closed, during the closing process of the door or lid, the hook head is already on the movement path of the pin shaft when the door or lid closes, but the spring between the hook head and the locking hook can deform, causing the hook head to rotate under the extrusion force of the pin shaft until the pin shaft is out of contact with the hook head and there is no force between them. Since the hook head is no longer extruded by the pin shaft, the elastic force of the spring drives the hook head to return to the limit position, on the path of the pin shaft rotating as the door or lid opens, restricting the opening of the door or lid.

[0058] It can be seen that when the door or lid of the equipment storage device is closed and the pin shaft thereon is restricted from moving in the opening direction of the door or lid by the hook head, the switch shaft must be rotated to release the restriction of the hook head on the pin shaft moving in the opening direction of the door or lid before the door or lid can be opened, while the reverse direction is not restricted. That is to say, the closing of the door or lid is not restricted by the hook head, thus realizing the association between the open state of the equipment storage device and the position of the switch shaft (hook head).

[0059] During the rotation of the switch shaft, the switch block rotates accordingly. The rotation process of the switch block controls the on and off states of the electrical switch. As needed, when the switch shaft is in the locked position, the switch block controls the electrical switch to be on, and when in the free position, the switch block controls the electrical switch to be off, or when the switch shaft is in the locked position, the switch block controls the electrical switch to be off, and when in the free position, the switch block controls the electrical switch to be on. Eventually, the open state of the equipment storage device lid is associated with the on or off state of the electrical switch.

Therefore, the appended claims are intended to be interpreted to include the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
