Description

Technical Field

[0001] The utility model belongs to the technical field of industrial plugs, in particular to an industrial plug that can be tightly connected. Background Art

[0002] Industrial plugs are durable electrical connection devices designed specifically for industrial environments. They are generally made of high-strength materials and can withstand harsh working conditions and frequent plugging and unplugging. Industrial plugs are designed with specialized pins and sockets to ensure stable and reliable power transmission. They come in a variety of specifications to accommodate different voltage, current, and power requirements. They are widely used in factories, construction sites, machinery, and other fields, providing safe and effective power connections for various industrial equipment and appliances, ensuring the normal operation of industrial production.

[0003] The Chinese patent publication number "CN209088146U" discloses an industrial plug with a tight connection, which includes an insulating seat and a boss. One end of the boss is connected to a hand-held seat, and the other end of the boss is provided with a positioning convex groove. One end of the insulating seat is provided with a mounting groove and an assembly groove. A metal sheet and a fuse are installed inside the mounting groove. A spring assembly is installed inside the assembly groove. The spring assembly includes an arc piece, a transition block, a positioning block, a convex block and an elastic rubber strip. In this industrial plug with a tight connection, a rubber layer is laid on the outer wall of the positioning convex groove, making the connection tighter and enhancing the waterproof and dustproof capabilities. The spring assembly can improve the tightness of the connection between the plug and the socket. The arc piece with a chamfered end can facilitate the plug to be inserted into the socket. A convex block is installed on the outer wall of the arc piece. The convex block is used for limiting. When the plug is inserted into the socket, the convex block will contact the inner wall of the socket, increasing friction and preventing the plug from slipping out due to external force during use.

[0004] However, although the above-mentioned device can assist in limiting and improve the stability of the plug connection by increasing friction during use, it still has certain defects and shortcomings in its specific application. First, it lacks a more stable rigid limiting structure during use as a whole. Obviously, the connection stability is insufficient by simply increasing friction. At the same time, it is not convenient to quickly remove the plug during use. The overall operation is cumbersome and inconvenient. It can be seen that it has certain defects and shortcomings in use and needs to be improved. Utility Model Content

[0005] In view of the problems mentioned in the background technology, the purpose of the present invention is to provide an industrial plug that can be tightly connected to solve the problems raised in the background technology.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A tightly connectable industrial plug comprises a socket and a plug body, the plug body being inserted into the interior of the socket, with limit slots being provided on both sides of the socket, a limit mechanism being fixedly mounted on both ends of the plug body on a side close to the socket, the outer ends of the limit mechanisms being inserted into the inner sides of the limit slots, a linkage assembly being fixedly connected to the top of the plug body, the linkage assembly being in close contact with the inner side of the limit mechanism, and a winding mechanism being fixedly connected to the end of the plug body on a side away from the socket;

[0008] The limiting mechanism includes a fixed block, which is fixedly installed at both ends of one side of the plug body close to the socket. A movable groove is provided on the inner side of the fixed block. The inner side of the movable groove is fixedly connected to a limiting spring. The outer end of the limiting spring is fixedly connected to a limiting frame. The outer end of the limiting frame passes through the fixed block. The top view of the limiting frame is concave. A card block is fixedly installed on the outer end of the limiting frame, and the card block is inserted into the inner side of the limiting groove.

[0009] As a preferred technical solution, an inner end of the card block close to the socket is provided with an inclined surface, and the overall top view shape of the card block is a right-angled trapezoid.

[0010] As an optimal technical solution, a linkage rod is fixedly connected to the top of the limiting frame, and a guide block is fixedly installed on the inner end of the linkage rod.

[0011] As a preferred technical solution, the linkage assembly includes a slide rail, which is fixedly connected to the top middle of the plug body. A slider is slidably connected inside the slide rail, and a guide plate is fixedly connected to the top of the slider.

[0012] As an optimal technical solution, the top of the guide plate is fixedly connected with an anti-skid push plate, and the top of the anti-skid push plate is provided with anti-skid grooves at equal intervals.

[0013] As a preferred technical solution, the guide plate has an end close to the plug that is shaped like an isosceles triangle when viewed from above, and the inner end of the guide block has an arc shape when viewed from above.

[0014] As an optimal technical solution, the winding mechanism includes a fixed frame, the outer side of the fixed frame is rotatably connected to the winding wheel, the top of the fixed frame is fixedly installed with a connecting frame, the outer end of the connecting frame is threadedly connected to a hand screw, the bottom of the hand screw passes through the connecting frame and is rotatably connected to a limiting arc plate, the top side of the limiting arc plate is fixedly connected to a support shaft, and the top of the support shaft passes through the connecting frame.

[0015] In summary, the present invention has the following beneficial effects:

[0016] First, a limit mechanism is provided. When the plug body is inserted into the socket, the socket contacts the inclined surface of the card block, causing it to be compressed, driving the limit frame to move outward. After the plug is fully inserted, the card block contacts the limit groove, and the socket limit is lost. The limit spring resets to move the limit frame inward, and the card block is inserted into the limit groove, thereby stabilizing the plug installation. The rigid limit of the card block and the limit groove can ensure a firm and precise connection between the plug and the socket, preventing accidental falling off and ensuring safe and reliable use.

[0017] Second, a linkage assembly is provided. When disassembling the plug and socket, the anti-slip push plate is manually pressed to push it to drive the slider and guide plate to slide. Because the guide plate is an isosceles triangle and the guide block is arc-shaped, the inclined surfaces and arc surfaces of the two guide each other. The guide block is pushed open to enable the linkage rod to push the limit frame outward, and the card block is pulled out. The plug and socket lose their limit and separate, realizing quick disassembly and assembly, and improving the overall disassembly and assembly convenience;

[0018] Third, a winding mechanism is set up. When in use, the excess wire of the plug can be wound around the winding wheel. After winding, the hand-screw is twisted to move the limiting arc plate down to fit the wire, thereby pressing the wire tightly and making it stably contact with the winding wheel. It can adaptively reel in the excess wire to avoid dragging and entanglement, making the wire layout of industrial equipment stable and compact, improving the stability and convenience of use. The support shaft supports the limiting arc plate to make it stable and movable, ensuring the stable positioning of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] Example

[0025] refer to Figures 1 to 4The present embodiment provides a tightly connected industrial plug, comprising a socket 1 and a plug body 2. The plug body 2 is inserted into the interior of the socket 1. Limiting grooves 4 are provided on both sides of the socket 1. Limiting mechanisms 3 are fixedly installed at both ends of the plug body 2 close to the socket 1. The outer ends of the limiting mechanisms 3 are inserted into the inner sides of the limiting grooves 4. A linkage component 5 is fixedly connected to the top of the plug body 2. The linkage component 5 and the inner side of the limiting mechanism 3 are tightly connected. A winding mechanism 6 is fixedly connected to the end of the plug body 2 away from the socket 1.

[0026] The limiting mechanism 3 includes a fixed block 31, which is fixedly installed at both ends of the side of the plug body 2 close to the socket 1. A movable groove 32 is provided on the inner side of the fixed block 31, and the inner side of the movable groove 32 is fixedly connected to the limiting spring 33. The outer end of the limiting spring 33 is fixedly connected to the limiting frame 34, and the outer end of the limiting frame 34 passes through the fixed block 31. The top view of the limiting frame 34 is concave. A card block 35 is fixedly installed on the outer end of the limiting frame 34, and the card block 35 is plugged into the inner side of the limiting groove 4. The plug-in design of the socket 1 and the plug body 2 cooperates with the limiting mechanism 3 fixedly installed at both ends of the side of the plug body 2 close to the socket 1, wherein the inner side of the fixed block 31 is provided with a movable groove 32 and connected to the limiting spring 33, and the outer end is fixedly connected to the concave limiting frame The bracket 34 has a card block 35 installed on its outer end, and the card block 35 can be inserted into the inner side of the limit groove 4 on both sides of the socket 1, so that the plug body 2 and the socket 1 can be tightly and firmly connected, which can effectively avoid accidental falling off and ensure the stability and reliability of power transmission. Secondly, the linkage assembly 5 on the top of the plug body 2 is fitted with the inner side of the limit mechanism 3, which facilitates the disassembly operation of the plug body 2 and the socket 1, making the disassembly and assembly process fast and convenient, greatly improving the convenience of use. Finally, the winding mechanism 6 on the side of the plug body 2 away from the end of the socket 1 can organize and store excess wires, avoiding the dragging and entanglement of the wires, making the wire layout of industrial equipment more compact and reasonable, and improving the overall stability and convenience of use.

[0027] refer to Figure 1-Figure 3The inner end of the card block 35 close to the socket 1 is provided with an inclined surface, and the overall top view shape of the card block 35 is a right-angled trapezoid. The inclined surface of the inner end of the card block 35 close to the socket 1 and the overall right-angled trapezoidal shape bring some significant advantages. This special shape design enables the inclined surface of the card block 35 to play a guiding role when the plug body 2 is inserted into the socket 1, making it easier for the plug body 2 to be combined with the socket 1, reducing the resistance during insertion, and achieving a smoother plugging operation. Moreover, the right-angled trapezoidal shape also ensures the stability of the card block 35 after being plugged into the limit groove 4, can better withstand external forces, ensure that the plug is tightly connected to the socket 1 and is not easy to loosen. In practical applications, such as in some industrial environments with vibration or external force interference, such a design can effectively ensure the reliability of the plug connection and avoid power interruption or failure caused by loose connection.

[0028] refer to Figure 1-Figure 3 The top of the limit frame 34 is fixedly connected to a linkage rod 36, and the inner end of the linkage rod 36 is fixedly installed with a guide block 37. The existence of the linkage rod 36 and the guide block 37 makes the operation of the limit mechanism 3 more centralized and convenient. The linkage rod 36 can extend the control of the limit frame 34 to a position that is more convenient to operate, so that the user can easily adjust the plugging state of the plug. Secondly, the setting of the guide block 37 can better cooperate with other related components, such as interacting with the linkage component 5, so as to achieve precise control of the plugging and separation of the plug.

[0029] refer to Figure 1-Figure 3 The linkage assembly 5 includes a slide rail 51, which is fixedly connected to the middle of the top of the plug body 2. The slide rail 51 is slidably connected to a slider 52 inside the slide rail 51, and a guide plate 53 is fixedly connected to the top of the slider 52. The slide rail 51 provides a stable moving path for the slider 52, ensuring the accuracy and reliability of the linkage action. The slider 52 can move smoothly along the slide rail 51, so that the guide plate 53 connected thereto can be accurately adjusted to the position as needed. The setting of the guide plate 53 can easily interact with other components to achieve effective control of the plug body 2 and the limit mechanism 3. This design improves the convenience and efficiency of plug operation. The user can control the relevant functions of the plug by simply pushing or pulling the guide plate 53. In actual use, for example, when the plug needs to be quickly connected or disconnected, the operation can be quickly and accurately achieved through the linkage assembly 5, reducing the operation time and difficulty.

[0030] refer to Figure 1-Figure 2The top of the guide plate 53 is fixedly connected with an anti-slip push plate 54, and the top of the anti-slip push plate 54 is evenly spaced with anti-slip grooves 55. The setting of the anti-slip push plate 54 makes the operation of the linkage component 5 more convenient and direct, increases the area of ​​hand contact, and is convenient for pushing or pulling. The presence of the anti-slip grooves 55 further enhances the anti-slip effect. Even in some relatively humid conditions or when the operator's hands are sweaty, it can ensure that there is no slipping during operation, thereby improving the stability and safety of the operation. This makes it possible to complete the action more accurately and quickly when plugging and unplugging the plug, reducing the possibility of misoperation.

[0031] refer to Figure 1-Figure 3 The guide plate 53 is shaped like an isosceles triangle when viewed from above at one end near the plug, and the inner end of the guide block 37 is shaped like an arc when viewed from above. The isosceles triangle design of the guide plate 53 enables it to have good guidance and precision when interacting with other components. The special shape of the isosceles triangle can ensure accurate docking with relevant components during movement, thereby achieving efficient force transmission and motion control, which is conducive to improving the accuracy and stability of plug operation, especially when fine plugging and unplugging actions are required. The arc-shaped design of the inner end of the guide block 37 increases the smoothness and softness when in contact with the guide plate 53. The arc shape can reduce friction and jamming, making the interaction between the guide block 37 and the guide plate 53 smoother and more natural, thereby improving the working efficiency and performance of the entire linkage assembly 5.

[0032] refer to Figure 4 The winding mechanism 6 includes a fixing frame 61, the outer side of the fixing frame 61 is rotatably connected to the winding wheel 62, the top of the fixing frame 61 is fixedly installed with a connecting frame 63, the outer end of the connecting frame 63 is threadedly connected to a hand screw 64, the bottom of the hand screw 64 passes through the connecting frame 63 and is rotatably connected to the limiting arc plate 65, the top side of the limiting arc plate 65 is fixedly connected to a support shaft 66, the top of the support shaft 66 passes through the connecting frame 63, and the winding wheel 62 outside the fixing frame 61 provides a special storage space for the wire, which is convenient for arranging the excess wire, making the working environment more tidy and orderly, and avoiding the confusion of wire entanglement. Secondly, the connecting frame 63 is threadedly connected to the hand screw 64, and the bottom limiting arc plate 65 can be driven up and down by rotating the hand screw 64. When the wire needs to be fixed, the hand screw 64 is tightened to press the limiting arc plate 65 down, which can firmly fix the wire on the winding wheel 62 to prevent the wire from loosening and falling out, thereby ensuring the stability of the winding. The setting of the support shaft 66 not only provides a guide for the lifting and lowering of the limiting arc plate 65, but also ensures the stability of its movement. Moreover, such a winding mechanism 6 is simple and practical in design, easy and quick to operate, and can be quickly operated when the wire length needs to be used or adjusted.

[0033] When the plug body 2 is fully inserted into the socket 1, the block 35 and the limiting groove 4 are in contact, and the block 35 loses the limit of the socket 1. The limiting spring 33 is reset and drives the limiting frame 34 to move inward. The inward movement of the limiting frame 34 can drive the block 35 to be inserted into the inner side of the limiting groove 4. At this time, the block 35 and the limiting groove 4 are mutually limited, and the plug body 2 can be stably inserted into the interior of the socket 1. During use, the rigid limit of the block 35 and the limiting groove 4 can promote the plug body 2 and the socket 1 to be firmly and precisely connected, and can prevent the plug body 2 from accidentally falling off.

[0034] When the plug body 2 and the socket 1 are separated, the sliding block 35 can be pulled out of the locking groove 4 by pulling out the locking block 35. When the locking block 35 is pulled out, the plug body 2 and the socket 1 are separated from each other, so that the socket 1 and the plug body 2 can be quickly separated from each other, making the overall disassembly and assembly of the device convenient and easy.

[0035] By setting up the winding mechanism 6, the device can be used to wind the excess wire of the plug body 2 around the outer surface of the winding wheel 62 during use. When the excess wire is wound, the limiting arc plate 65 can be driven downward by twisting the hand screw 64. The limiting arc plate 65 moves down and fits the wire on the outer surface of the winding wheel 62. The limiting arc plate 65 can be pressed against the wire by contacting the limiting arc plate 65 with the wire. At this time, the wire can be stably contacted with the winding wheel 62, so that the device can adaptively reel in the excess wire during use to avoid the situation where the wire is dragged and entangled, so that the wire of the industrial equipment can be arranged more stably and compactly, which can improve the overall stability and convenience of use of the device. During the adjustment process, the setting of the support shaft 66 can support the limiting arc plate 65, so that the limiting arc plate 65 can be stably moved up and down, so that the device can be positioned more stably.
