Description

Technical Field

[0001] This invention relates to the field of industrial control computer technology, and more particularly to industrial control computer USB port locks and industrial control computer USB ports. Background Technology

[0002] An industrial control computer (ICC) is a computer system specifically designed and manufactured for industrial environments. It is widely used in automation, control systems, data acquisition, monitoring, and communication. Compared to ordinary computers, ICCCs are more stable, reliable, and durable, and are primarily used in various complex industrial applications.

[0003] When using existing industrial control computers, they connect to external data transmission devices via USB ports for data transfer. Because industrial control computers sometimes operate in dusty environments, when dust enters the USB port, it can cover the metal contacts on the USB port. This can cause instability in the electrical signal when the external data transmission device transmits data to the industrial control computer via the USB port, affecting the normal operation of the industrial control computer. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an industrial control computer USB port lock and an industrial control computer USB port.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Industrial PC USB port lock, including:

[0007] A frame is disposed on the outer surface of the USB port of the industrial control computer. An opening is provided inside the frame, and multiple arc grooves are provided on the inner walls of the opening on both sides. Insertion holes are provided on the inner walls of the multiple arc grooves.

[0008] At least two plates are symmetrically arranged inside the opening. The two plates are rotatably installed between the inner walls on opposite sides of the opening via a pivot. A first groove is formed on the outer surface of one side of each of the two plates, and through holes are formed at both ends of each plate.

[0009] At least two sets of plugs are arranged in pairs between the inner walls of the first slot. The two plugs in each set are configured to move away from or towards each other along the central axis of the first slot. One end of each plug is inserted through a through hole inside the plug hole. The plugs are configured to move along the inner wall of the arc groove when the plate rotates. Inside the opening of the frame, two plates are rotated and installed through a pivot, which can block the corresponding USB ports, thus blocking the USB ports when they are not in use and preventing external dust from entering the USB ports.

[0010] As a further embodiment of the present invention, the insertion hole is connected to the interior of the arc groove, and the arc groove and the rotating shaft are located at the same center to ensure normal rotation of the insertion block. A torsion spring is provided at the end of the rotating shaft, and the two plates can be closed by the elastic force of the torsion spring.

[0011] As a further embodiment of the present invention, two second grooves are symmetrically formed on the outer surface of one side of the plate, and both second grooves are connected to the first groove. A slider is slidably installed on the inner wall of each of the two second grooves. An inclined groove is formed through the outer surface of the insert near the slider end. A guide post is fixedly connected to one end of the slider. The guide post is slidably installed with the inner wall of the inclined groove. When the slider slides upward along the second groove, the two inserts move closer to each other through the cooperation of the guide post and the inclined groove. Conversely, when the slider slides downward along the second groove, the two inserts move away from each other through the cooperation of the guide post and the inclined groove, thereby releasing the restriction on the two plates.

[0012] As a further embodiment of the present invention, a second spring is fixedly connected to the end face of the other end of the slider, and the other end of the second spring is fixedly connected to the inner wall of the second groove. A limit post is fixedly connected to the end face of the other end of the slider, and the second spring is sleeved on the outer surface of the limit post. Through the elastic force of the second spring, when the slider slides upward along the second groove, the two insert blocks move closer to each other through the cooperation of the guide post and the inclined groove, and the downward stroke of the slider is limited by the limit post.

[0013] As a further embodiment of the present invention, a third groove is provided through the interior of the slider, and an L-shaped support block is rotatably installed between the inner walls of the third groove. The bottom end face of the L-shaped support block is flush with the bottom wall of the first groove. When the bottom end face of the L-shaped support block is flush with the bottom wall of the first groove, the L-shaped support block will not rotate arbitrarily between the inner walls of the third groove. This arrangement ensures that when the slider slides down along the second groove, the movement of the two insert blocks away from each other can be normally achieved through the cooperation of the guide post and the inclined groove.

[0014] As a further embodiment of the present invention, a cover plate is fixedly installed between the inner walls of the first groove and the second groove. Two through grooves are symmetrically opened on the outer surface of the cover plate. The top end of the L-shaped support block passes through the through groove and is slidably installed with its inner wall. The through groove makes the top end of the L-shaped support block protrude a certain distance from the outer surface of the cover plate, so as to facilitate the positioning of the hole of the USB plug.

[0015] As a further embodiment of the present invention, the bottom wall of the second groove is provided with an inclined surface, and the end face of the bottom of the L-shaped support block abuts against the inclined surface. When the slider slides down along the second groove, the bottom end of the L-shaped support block will also slide into the position of the inclined surface. At this time, because the inclined surface is set at an angle, as the L-shaped support block continues to slide down, the L-shaped support block will also rotate at a certain angle until the top of the L-shaped support block completely slides into the inside of the through groove. At this time, the L-shaped support block will also completely come out from the hole of the USB plug.

[0016] As a further embodiment of the present invention, the L-shaped support block is L-shaped in shape. The L-shaped support block is rotatably installed between the inner walls of the third groove by means of a rotating rod. The rotating rod is located at the bottom end of the L-shaped support block. This arrangement ensures that the L-shaped support block can rotate correctly at a certain angle, so as to completely enter the interior of the through groove without blocking the USB plug.

[0017] As a further embodiment of the present invention, the top and bottom walls of the opening are provided with countersunk holes, and a pressure plate is slidably installed between the inner walls of the countersunk holes. A rod is fixedly provided on the outer surface of one side of the pressure plate, one end of the rod penetrates the outer surface of the frame, and a first spring is fixedly provided on the outer surface of one side of the pressure plate. The other end of the first spring is fixedly connected to the inner wall of the countersunk hole.

[0018] As a further embodiment of the present invention, the industrial control computer USB port includes the aforementioned industrial control computer USB port lock.

[0019] This invention features two plates mounted inside the opening of the frame via a rotating shaft. A torsion spring is positioned at the shaft, and its elastic force allows the two plates to close, blocking the corresponding USB port. This prevents external dust from entering the USB port and affecting subsequent data transmission stability, ensuring the normal operation of the industrial control computer. Furthermore, as the slider slides upward along the second groove, the guide post and inclined groove work together to move the two inserts closer together. Conversely, as the slider slides downward along the second groove, the guide post and inclined groove work together to move the two inserts away from each other, thus releasing the restriction on the two plates.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] To prevent external dust and foreign objects from entering the USB port of the industrial control computer when it is not in use, such as... Figure 1 and Figure 2 As shown, this invention proposes a USB port lock for an industrial control computer, comprising: a frame 100, at least two boards 200, and at least two sets of plug blocks 500. Specifically, as... Figure 1 As shown, the frame 100 is fixedly installed on the outer surface of the industrial control computer's USB port and completely covers the USB port. The frame 100 has an opening inside, which facilitates the insertion and removal of the USB plug.

[0038] To seal the opening, such as Figure 3 and Figure 4 As shown in this embodiment, since there are two USB ports, two boards 200 are provided. The two boards 200 are symmetrically arranged inside the opening. The two boards 200 are rotatably installed between the inner walls on opposite sides of the opening via a pivot. By setting the two boards 200, the corresponding USB ports can be blocked, so that the USB ports are blocked when not in use, preventing external dust from entering the USB ports and affecting the stability of subsequent data transmission, thus ensuring the normal operation of the industrial control computer. It should be noted that when the USB plug is inserted into the USB port, the board 200 will rotate to the inner wall of the frame 100 and fit against the inner wall, thereby filling the gap between the USB plug and the frame 100, avoiding large gaps during use, and preventing foreign objects and dust from entering the frame 100 during use.

[0039] When the two boards 200 block the USB port, in order to restrict the position of the two boards 200, in this embodiment, as follows: Figure 5 and Figure 6 As shown, the inner walls of the opening on both sides are provided with multiple arc grooves 110, and each of the multiple arc grooves 110 has an insertion hole 120. The outer surface of one side of each of the two plates 200 is provided with a first groove 210, and both ends of the plate 200 have through holes 220. It should be noted that the depth of the insertion hole 120 is deeper than the depth of the arc groove 110. In this embodiment, the insertion blocks 500 are arranged in pairs between the inner walls of the first grooves 210. A pair of insertion blocks 500 are configured to move away from or towards each other along the central axis of the first grooves 210. When the two insertion blocks 500 move away from each other, one end of the insertion block 500 penetrates the through hole 220 and is positioned inside the insertion hole 120. Thus, the cooperation between the insertion block 500 and the insertion hole 120 restricts the position of the plate 200, preventing it from rotating and opening arbitrarily. When the plug blocks 500 move closer to each other, they slide out from inside the socket 120, thereby releasing the restriction of the board 200 and facilitating the insertion of the USB plug into the USB port. To facilitate the opening of the board 200, the plug blocks 500 are configured such that when the board 200 rotates, they can move along the inner wall of the arc groove 110. At this time, the plug blocks 500 move inside the arc groove 110 without affecting the opening of the board 200. In order for the plug blocks 500 to slide from the socket 120 into the arc groove 110, the socket 120 and the arc groove 110 are connected. The arc groove 110 and the rotating shaft are located at the same center. Furthermore, in order for the two boards 200 to close again when the USB port is not in use, in this embodiment, a torsion spring is provided at the end of the rotating shaft. The elastic force of the torsion spring enables the two boards 200 to close.

[0040] In this embodiment, in order to control the two insert blocks 500 to move away from or towards each other along the central axis of the first slot 210, such as... Figure 6 and Figure 7 As shown, two second grooves 230 are symmetrically formed on one side of the outer surface of the plate 200. Both second grooves 230 are connected to the first groove 210. A slider 600 is slidably mounted on the inner wall of each of the two second grooves 230. Figure 8 As shown, a slanted groove 510 is formed through the outer surface of the insert block 500 near the slider 600. A guide post 640 is fixedly connected to one end of the slider 600. The guide post 640 is slidably installed with the inner wall of the slanted groove 510. When the slider 600 is in the... Figure 6As shown, when the slider 600 slides upward along the second groove 230, the two insert blocks 500 move closer to each other through the cooperation of the guide post 640 and the inclined groove 510. Conversely, when the slider 600 slides downward along the second groove 230, the two insert blocks 500 move away from each other through the cooperation of the guide post 640 and the inclined groove 510, thereby releasing the restriction on the two plates 200.

[0041] In order to enable the slider 600 to slide downwards along the second groove 230, as Figure 9 and Figure 10 As shown, a third groove 610 is formed through the interior of the slider 600. An L-shaped support block 700 is rotatably installed between the inner walls of the third groove 610. A cover plate 300 is fixedly installed between the inner walls of the first groove 210 and the second groove 230. Two through grooves 310 are symmetrically formed on the outer surface of the cover plate 300. The top of the L-shaped support block 700 passes through the through groove 310 and is slidably installed with its inner wall. When preparing to insert a USB plug, the operator first puts the hole of the USB plug on the top of the two L-shaped support blocks 700, and then presses the two L-shaped support blocks 700 down through the USB plug. Since the end face of the bottom of the L-shaped support block 700 is flush with the bottom wall of the first groove 210, the slider 600 is driven to slide down along the second groove 230. At this time, the two plug blocks 500 move away from each other and slide out from the plug hole 120 into the arc groove 110. When the L-shaped support block 700 is not pressed, in order for the slider 600 to slide upward along the second groove 230 to reset, the two insert blocks 500 are reinserted into the socket 120, as follows: Figure 7 As shown, a second spring 620 is fixedly connected to the end face of the other end of the slider 600. The other end of the second spring 620 is fixedly connected to the inner wall of the second groove 230. A limit post 630 is fixedly connected to the end face of the other end of the slider 600. The second spring 620 is sleeved on the outer surface of the limit post 630, and the downward stroke of the slider 600 is limited by the limit post 630.

[0042] It is important to note that the distance between the two L-shaped support blocks 700 is matched with the width of the USB plug hole. When the two L-shaped support blocks 700 are inserted into the USB plug hole, they can position the USB plug and prevent it from being misaligned when inserted into the USB port. In actual use, if one of the two L-shaped support blocks 700 is not fully pressed down, the board 200 cannot be completely released from its limit. At this time, the board 200 cannot be opened. This setting serves as a reminder to the operator that the USB plug has been misaligned or misaligned.

[0043] In this embodiment, when the two boards 200 are rotated open, in order to smoothly insert the USB plug into the USB port, as follows: Figure 7As shown, the bottom wall of the second groove 230 is provided with an inclined surface 240. The end face of the bottom of the L-shaped support block 700 abuts against the inclined surface 240. When the slider 600 slides down along the second groove 230, the bottom end of the L-shaped support block 700 will also slide into the position of the inclined surface 240. At this time, because the inclined surface 240 is inclined, as the L-shaped support block 700 continues to slide down, the L-shaped support block 700 will also rotate a certain angle until the top of the L-shaped support block 700 is completely slid into the interior of the through groove 310. At this time, the L-shaped support block 700 will also completely come out from the hole of the USB plug, so that the USB plug can be smoothly inserted into the USB port.

[0044] It should be noted that when the plug 500 slides between the inner walls of the arc groove 110, because the arc groove 110 has a certain depth, if the USB plug is deflected during insertion, the slider 600 will not be able to slide the plug 500 out of the arc groove 110 when sliding down along the second groove 230, thus preventing the board 200 from being fully opened. This setting serves as a reminder to the operator that the USB plug is deflected and should be adjusted.

[0045] To ensure the L-shaped support block 700 can rotate correctly, the L-shaped support block 700 is L-shaped in shape. The L-shaped support block 700 is rotatably mounted between the inner walls of the third groove 610 via a rotating rod. Figure 9 As shown, the rotating rod is positioned at the bottom end of the L-shaped support block 700.

[0046] To allow operators to visually observe whether the two panels 200 are fully opened when they are opened, such as... Figure 5 As shown, countersunk holes 130 are provided on both the top and bottom walls of the opening. A pressure plate 400 is slidably installed between the inner walls of the countersunk holes 130. A rod is fixedly installed on the outer surface of one side of the pressure plate 400. One end of the rod penetrates the outer surface of the frame 100. A first spring 410 is fixedly installed on the outer surface of one side of the pressure plate 400. The other end of the first spring 410 is fixedly connected to the inner wall of the countersunk hole 130. When the plate 200 is opened, it abuts against the outer surface of the pressure plate 400, thereby causing the rod to extend out of the outer surface of the frame 100.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
