Description

Technical Field

[0001] The utility model relates to the technical field of industrial computer plug fixing, in particular to a USB plug locking mechanism for an industrial computer. Background Art

[0002] Industrial control computers, abbreviated as IPCs, are modified based on personal computers so that their system structure and functional module divisions are more suitable for the requirements of industrial process control. In addition to the rich software resources and easy development of general microcomputers, IPCs integrate communication and control of various electromechanical equipment, process equipment, etc. in the production process through bus connections. They have the characteristics of high reliability, good real-time performance, good hardware configuration scalability and maintainability. Since industrial production scenarios are generally more rigorous, in order to ensure the stability of the line connection between the IPC and various key equipment, a special USB plug locking mechanism is required to ensure the reliability of line connection and communication.

[0003] However, existing USB plug locking mechanisms for industrial computers generally have two types of problems. One type is fixed by bolts. Although this makes the line connection highly reliable, when the USB plug needs to be unplugged, it is necessary to use a screwdriver to open the bolts first, which is very inconvenient. The other type of plug locking mechanism often has the problem of unreliable installation lines, which may lead to unstable line signal transmission. Based on this, a USB plug locking mechanism for industrial computers that can solve the above problems is proposed. Utility Model Content

[0004] In order to solve the technical problem of locking the plug of an industrial computer, the utility model provides a USB plug locking mechanism for an industrial computer.

[0005] The utility model is implemented by the following technical solutions: a USB plug locking mechanism for an industrial computer, comprising an industrial computer mounting plate, a USB socket fixedly connected to the upper side of the industrial computer mounting plate, a limiting cylinder fixedly connected to the upper side of the USB socket, a plurality of cylindrical limiting grooves being provided on the cylindrical outer surface of the limiting cylinder, a plurality of spherical limiting grooves being provided on the cylindrical inner surface of the limiting cylinder, each of the cylindrical limiting grooves being connected to each of the spherical limiting grooves, a plurality of the cylindrical limiting grooves being distributed in a circular array, a spherical stopper being provided inside each of the cylindrical limiting grooves, a USB plug mechanism connected to the USB socket being provided on the inner side of the limiting cylinder, and a push cylinder mechanism for locking the USB plug inserted into the limiting cylinder being provided on the outer side of the limiting cylinder.

[0006] As a further improvement of the above-mentioned solution, the USB plug mechanism includes a USB interface that is paired with a USB socket, a plug rod is fixedly connected to the upper side of the USB interface, the outer side of the plug rod is slidably connected to the inner side of the limiting cylinder, a card slot is provided on the plug rod, and the card slot is cooperated with a plurality of the spherical stops, and a wiring mechanism is provided on the upper side of the plug rod to facilitate the connection of the USB line.

[0007] As a further improvement of the above solution, the wiring mechanism includes a plug back fixedly connected to the upper side of the plug rod, and the upper side of the plug back is connected to a USB connection line.

[0008] As a further improvement of the above-mentioned solution, the push cylinder mechanism includes a push cylinder slidably connected to the outer side of the USB socket, and the inner side of the push cylinder is provided with a push ring locking mechanism that enables multiple spherical blocks to move back and forth along the channel composed of the cylindrical limiting groove and the spherical limiting groove.

[0009] As a further improvement of the above-mentioned solution, the push ring locking mechanism includes a retaining ring fixedly connected to the inner side of the push cylinder, the inner side of the retaining ring is slidingly connected to the outer side of the limiting cylinder, and the upper side of the limiting cylinder is fixedly connected with a baffle, which is used to prevent the push cylinder from falling off from the upper end of the limiting cylinder. An elastic component mechanism is provided between the retaining ring and the USB socket to automatically reset the push cylinder.

[0010] As a further improvement of the above solution, the elastic component mechanism includes a spring arranged between the retaining ring and the USB socket, the upper end of the spring is fixedly connected to the lower side of the retaining ring, and the lower end of the spring is fixedly connected to the upper side of the USB socket.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model sets a push cylinder mechanism. When the push cylinder moves downward and the plug back is pulled upward, the spherical stopper moves outward along the channel composed of the spherical limit groove and the cylindrical limit groove, thereby releasing the slot on the plug rod; conversely, when the push cylinder moves upward under the rebound effect of the spring force, the retaining ring squeezes the spherical stopper into the channel, and the spherical stopper forms a locking function for the slot on the plug rod, which is easy to operate and simple to use.

[0013] 2. The utility model provides a push cylinder that can move up and down, and provides a plurality of spherical stops in a circular array on the surface of the limit cylinder. The plurality of spherical stops can simultaneously and highly symmetrically limit the card slot, which is conducive to more accurate and balanced docking between the USB interface and the USB socket, and more stable signal data transmission.

[0021] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] Example:

[0023] Please combine Figure 1-Figure 5 The present embodiment of a USB plug locking mechanism for an industrial computer includes an industrial computer mounting plate 1, and a USB socket 2 is fixedly connected to the upper side of the industrial computer mounting plate 1. Figure 4 As shown, an interface is provided at the bottom inner side of the USB socket 2, and a limiting cylinder 10 is fixedly connected to the upper side of the USB socket 2. The outer diameter of the limiting cylinder 10 is smaller than the diameter of the USB socket 2, and four cylindrical limiting grooves 12 are provided on the cylindrical outer surface of the limiting cylinder 10. The inner diameter of the cylindrical limiting groove 12 is adapted to the spherical stopper 7, and four spherical limiting grooves 13 are provided on the cylindrical inner surface of the limiting cylinder 10. It should be noted that the diameter of the maximum notch of the spherical limiting groove 13 is slightly smaller than the diameter of the spherical stopper 7, each cylindrical limiting groove 12 is connected to each spherical limiting groove 13, and multiple cylindrical limiting grooves 12 are distributed in a circular array, and a spherical stopper 7 is provided inside each cylindrical limiting groove 12. The inner side of the limiting cylinder 10 is provided with a USB plug mechanism connected to the USB socket 2, and the outer side of the limiting cylinder 10 is provided with a push cylinder mechanism for locking the USB plug inserted into the limiting cylinder 10.

[0024] The USB plug mechanism includes a USB interface 11 that is paired with the USB socket 2. The upper side of the USB interface 11 is fixedly connected to a plug rod 9. The outer side of the plug rod 9 is slidably connected to the inner side of the limit cylinder 10. A card slot 8 is provided on the plug rod 9. In this embodiment, the groove cross-section of the card slot 8 is trapezoidal. In other embodiments, the groove shape can be set to semicircular, which falls within the protection scope of the present utility model. The card slot 8 is provided in conjunction with four spherical blocks 7. The upper side of the plug rod 9 is provided with a wiring mechanism that facilitates the connection of the USB line.

[0025] Please combine Figure 1 As shown, the wiring mechanism includes a plug back 4 fixedly connected to the upper side of the plug rod 9, and the upper side of the plug back 4 is connected to the USB connection line 5.

[0026] Please combine Figure 1 As shown, the push cylinder mechanism includes a push cylinder 3 that is slidably connected to the outer side of the USB socket 2. A rubber pad that increases friction is provided on the outer side of the push cylinder 3 to facilitate the user to exert force. A push ring locking mechanism is provided on the inner side of the push cylinder 3 to enable the four spherical blocks 7 to move back and forth along the channel composed of the cylindrical limiting groove 12 and the spherical limiting groove 13.

[0027] Please combine Figure 4 As shown, the push ring locking mechanism includes a retaining ring 15 fixedly connected to the inner side of the push cylinder 3, the inner side of the retaining ring 15 is slidably connected to the outer side of the limiting cylinder 10, and the upper side of the limiting cylinder 10 is fixedly connected with a baffle 6, which is used to prevent the push cylinder 3 from falling off from the upper end of the limiting cylinder 10. An elastic component mechanism is provided between the retaining ring 15 and the USB socket 2 to automatically reset the push cylinder 3.

[0028] It should be noted that the retaining ring 15 here plays an important role, which is used to push the spherical stopper 7 to the innermost side of the spherical limiting groove 13. Therefore, the inner diameter of the retaining ring 15 is slightly larger than the outer diameter of the limiting cylinder 10. At the same time, the thickness of the retaining ring 15, that is, the distance between the inner side of the push cylinder 3 and the outer side of the limiting cylinder 10, needs to be smaller than the diameter of the spherical stopper 7.

[0029] Please combine Figure 5 As shown, the elastic component mechanism includes a spring 14 arranged between the retaining ring 15 and the USB socket 2. The spring 14 is mainly used for automatic rebound and pushing up the push cylinder 3. The upper end of the spring 14 is fixedly connected to the lower side of the retaining ring 15, and the lower end of the spring 14 is fixedly connected to the upper side of the USB socket 2.

[0030] The implementation principle of a USB plug locking mechanism for an industrial computer in the embodiment of the present application is as follows: when the user connects the USB plug, he first pushes the push tube 3 downward, and then inserts the insertion rod 9 into the limiting tube 10. At this time, the side wall of the insertion rod 9 pushes the spherical stopper 7 protruding from the surface of the spherical limiting groove 13 outward. When the USB interface 11 is successfully docked with the USB socket 2, the push tube 3 is released. Under the action of the rebound of the spring 14, the retaining ring 15 squeezes the spherical stopper 7 protruding from the outside of the cylindrical limiting groove 12 inward, so that the spherical stopper 7 is locked in the groove 8 to form a locking effect; when the user needs to unplug the USB plug, the user pushes the push tube 3 downward, and then pulls out the plug back 4. When the insertion rod 9 moves upward, the inner surface of the locking groove 8 pushes the spherical stopper 7 outward, and the insertion rod 9 can be smoothly pulled out.

[0031] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
