Description

Technical Field

[0001] The utility model belongs to the technical field of distribution cabinets, and particularly relates to an alarm device for an unclosed distribution cabinet door. Background Technique

[0002] When the existing production workshop staff open the distribution cabinet for operation, the lighting lamp inside the cabinet automatically turns on. After the operation is completed, the staff close the cabinet door and the lighting lamp automatically turns off. There are many distribution cabinets in the production workshop. After the staff open the distribution cabinet for operation, they are prone to negligence and forget to close the cabinet door, or leave after the cabinet door is not closed tightly with a large gap. At this time, the lighting lamp inside the cabinet is always on, resulting in waste of electric energy. In addition, the dust in the production workshop enters from the gap of the cabinet door, causing dust accumulation on electrical components and forming an electrical safety hazard. Summary of the Invention

[0003] The purpose of the utility model is to solve the problems existing in the prior art, and provides an alarm device for an unclosed distribution cabinet door, which can ensure that the cabinet door is closed properly, thereby effectively avoiding waste of electric energy, and at the same time preventing dust in the production workshop from entering through the gap of the cabinet door, and avoiding the situation of electrical safety accidents caused by dust accumulation on electrical components.

[0004] To achieve the above purpose, the utility model is realized by adopting the following technical solution: An alarm device for an unclosed distribution cabinet door includes an alarm installed on the outer surface of the cabinet door, an insertion block installed on the inner side of the cabinet door, and an alarm switch installed on the inner side wall of the distribution cabinet and adapted to the insertion block. The alarm switch includes a limiting frame installed on the inner side wall of the distribution cabinet. A guiding rod extending into the inside of the limiting frame is provided on the inner top wall of the distribution cabinet. A power connection rod is provided at the bottom end of the guiding rod. An electric connection slider sleeved on the surfaces of the guiding rod and the power connection rod is provided inside the limiting frame. An insertion opening adapted to the insertion block is opened on the side of the limiting frame facing the cabinet door.

[0005] By the above technical means, when the cabinet door is not closed or not completely closed, since the alarm switch cannot be triggered, the alarm will keep alarming, thus playing a reminder effect on the staff. After the cabinet door is completely closed, the insertion block on the inner side of the cabinet door triggers the alarm switch, so that the alarm switch disconnects the power supply, and the alarm can be stopped, effectively avoiding the situation that the lighting lamp inside the cabinet is always on due to the unclosed cabinet door, resulting in waste of electric energy and dust entering the distribution cabinet to cause electrical safety hazards.

[0006] Optionally, a notch communicating with the limiting frame is opened on one side of the distribution cabinet close to the cabinet door. Through this notch, when the cabinet door is closed, the insertion block can be more easily inserted into the limiting frame.

[0007] Optionally, the top view shape of the notch is a right trapezoid and is communicated with the socket. Since the insertion block moves in an arc during the closing process of the cabinet door, opening a notch with a right trapezoid top view shape can avoid the problem of movement interference between the insertion block and the power distribution cabinet.

[0008] Optionally, both the top surface of the insertion block and the side away from the hinge of the cabinet door are provided with inclined cut surfaces. The bottom surface of the power connection slider is provided with a bottom inclined notch adapted to the inclined surface of the top surface of the insertion block.

[0010] Optionally, the guide rod is an insulating rod body, and the power connection rod is a copper rod. When the power connection slider slides upward until the power connection rod is completely exposed from the power connection slider, the circuit path between the power connection slider and the power connection rod will be disconnected, causing the alarm to stop alarming.

[0011] Optionally, the length of the guide rod is less than the height of the power connection slider. With such a design, the power connection slider can have the opportunity to slide out of the power connection rod, thereby achieving the purpose of power-off.

[0012] Optionally, a jack vertically penetrating the power connection slider is provided on the power connection slider. The inner wall of the jack is embedded with a power connection copper sleeve adapted to the power connection slider, and the inner wall of the power connection copper sleeve is in contact with the outer side wall of the guide rod. The power connection copper sleeve contacts the power connection rod, thus completing the circuit path.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: 1. When the cabinet door is not closed or not completely closed, since the alarm switch cannot be triggered, the alarm will continuously alarm, thus reminding the staff. After the cabinet door is completely closed, the insertion block on the inner side of the cabinet door triggers the alarm switch, disconnecting the power supply of the alarm switch, and the alarm can be stopped, effectively avoiding the problems of continuous lighting of the internal lighting of the cabinet due to improper closing of the cabinet door, resulting in waste of electric energy and potential electrical safety hazards caused by dust entering the power distribution cabinet; 2. Since the insertion block moves in an arc during the closing process of the cabinet door, opening a notch with a right trapezoid top view shape can avoid the problem of movement interference between the insertion block and the power distribution cabinet.

[0022] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0023] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "middle", "upper", "lower", "left", "right", "inside", "outside", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0024] As Figure 1-2 shown, the specific solution of the embodiment is as follows: An alarm device for indicating that the cabinet door of a power distribution cabinet is not properly closed includes an alarm 3 provided on the outer surface of the cabinet door 2, a plug block 4 provided inside the cabinet door 2, and an alarm switch 5 provided on the inner side wall of the power distribution cabinet 1 and adapted to the plug block 4.

[0025] As Figure 1-2As shown in the figure, in this embodiment, a door lock adapted to the power distribution cabinet is provided on the surface of the cabinet door 2. At the same time, an elastic member is provided on the inner side of the cabinet door and close to the connection side. The elastic member can be a torsion spring or a spring sheet. One side of the torsion spring is connected to the cabinet door 2, and the other side of the torsion spring is connected to the power distribution cabinet 1. When closing the door, the cabinet door 2 will squeeze the elastic member. If the door lock does not lock the cabinet door 2, the cabinet door 2 will be bounced open again under the action of the torsion spring. Therefore, only when the operator closes and locks the cabinet door, the cabinet door is considered to be properly closed.

[0026] When the cabinet door 2 is not closed or not properly closed, the insertion block 4 cannot trigger the alarm switch 5, so that the alarm 3 is always in the normal circuit state, and the alarm state of the alarm 3 continues until the cabinet door 2 is completely closed. Only then can the insertion block 4 trigger the alarm switch 5 to disconnect the circuit of the alarm 3, so that the alarm 3 stops alarming. This effectively avoids the constant lighting of the lighting in the cabinet caused by the improper closing of the cabinet door 2, resulting in waste of electric energy and the entry of dust into the power distribution cabinet 1, causing potential electrical safety hazards.

[0027] As Figures 4-6 shown, in this embodiment, the alarm switch 5 includes a limiting frame 51 provided on the inner side wall of the power distribution cabinet 1. A guide rod 52 extending into the interior of the limiting frame 51 is provided on the inner top wall of the power distribution cabinet 1. A power connection rod 53 is provided at the bottom end of the guide rod 52. An electric connection slider 54 sleeved on the surfaces of the guide rod 52 and the power connection rod 53 is provided inside the limiting frame 51. An insertion port 55 adapted to the insertion block 4 is provided on the side of the limiting frame 51 facing down the cabinet door 2.

[0028] Among them, the diameter of the guide rod 52 is equal to the diameter of the power connection rod 53. Through this, the electric connection slider 54 can slide smoothly on the surfaces of the guide rod 52 and the power connection rod 53.

[0029] Secondly, the guide rod 52 is an insulating rod body, and the power connection rod 53 is a copper rod. When the electric connection slider 54 slides upward until the power connection rod 53 is completely exposed from the electric connection slider 54, the circuit connection between the electric connection slider 54 and the power connection rod 53 will be disconnected, so that the alarm 3 stops alarming.

[0030] It should be noted that an internal wire connecting the power connection rod 53 is provided at the center of the guide rod 52. At the same time, a spring wire is also provided at the top end of the electric connection slider 54. The electric connection slider 54 contacts the power connection rod 53. The power connection rod 53 is connected to one end of the power supply configured for the alarm 3 in the power distribution cabinet 1 through the internal wire, while the electric connection slider 54 is connected to the other end of the power supply configured for the alarm 3 in the power distribution cabinet 1 through the spring wire. The power supply is directly connected to the alarm 3 through a wire.

[0031] When the cabinet door 2 is opened or not properly closed, the power connection slider 54, the power supply, the alarm 3, and the power connection rod 53 form an electrical circuit path, and the alarm 3 will continuously sound an alarm. When the cabinet door 2 is completely closed, the insertion block 4 is inserted into the limiting frame 51, pushing the power connection slider 54 upwards, causing the power connection rod 53 to disengage from the power connection slider 54, thereby disconnecting the circuit and stopping the alarm of the alarm 3.

[0032] In addition, a jack vertically penetrating the power connection slider 54 is provided on the power connection slider 54, and a power connection copper sleeve adapted to the power connection slider 54 is embedded in the inner wall of the jack. The inner wall of the power connection copper sleeve is in contact with the outer side wall of the guiding rod 52. The power connection copper sleeve is in contact with the power connection rod 53 to complete the electrical circuit path.

[0033] It should be noted that in this embodiment, the alarm 3 uses an audible and visual alarm 3, and in actual production, a buzzer or a flashing light can also be used instead.

[0034] As Figure 4 shown, the length of the guiding rod 52 is less than the height of the power connection slider 54. At the same time, the height of the power connection rod 53 is less than the thickness of the insertion block 4. Therefore, when the insertion block 4 is inserted into the limiting frame 51, the height that the power connection slider 54 moves exceeds the length of the power connection rod. With such a design, the power connection slider 54 can have the opportunity to slide out of the power connection rod 53 after the insertion block is completely inserted into the limiting frame 51, thereby achieving the purpose of power-off.

[0035] As Figure 3 shown, both the top surface of the insertion block 4 and the side away from the hinge of the cabinet door 2 are provided with bevel cuts. At the same time, a bottom bevel notch 6 adapted to the top surface bevel of the insertion block 4 is provided on the bottom surface of the power connection slider 54. The bevel surfaces of the power connection slider 54 and the insertion block 4 cooperate with each other, enabling the insertion block 4 to be smoothly inserted into the limiting frame 51 to push up the power connection slider 54.

[0036] As Figure 1 、 Figure 7 shown, a notch 6 communicating with the limiting frame 51 is provided on one side of the power distribution cabinet 1 close to the cabinet door 2. The top view shape of the notch 6 is a right trapezoid and is communicated with the socket 55. Since the insertion block 4 moves in an arc trajectory during the closing process of the cabinet door 2, a notch 6 with a top view shape of a right trapezoid is provided. Through this notch 6, when the cabinet door 2 is closed, the insertion block 4 can be more easily inserted into the limiting frame 51, and the problem of movement interference between the insertion block 4 and the power distribution cabinet 1 can be avoided.

[0037] As Figure 4 、 Figure 5, the working principle of the above embodiment is as follows: when the cabinet door 2 is opened or not completely closed, the insertion block 4 cannot push the power connection slider 54 out of the range of the power connection rod 53, so that the circuit of the alarm 3 remains in a conductive state all the time. Therefore, the alarm 3 will keep alarming. When the cabinet door 2 is completely closed, the insertion block 4 will push the power connection slider 54 out of the range of the power connection rod 53, so that the circuit of the alarm 3 forms an open circuit state, and the alarm 3 can be stopped from alarming.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
