A quick mating plug with a portable locking structure

Abstract

This utility model belongs to the field of plug technology, specifically relating to a quick-connect plug with a convenient locking structure. It includes a socket and a compatible plug. The plug has a conductive base installed inside. External force contact plates are fitted onto both sides of the socket. A first horizontal axis is connected to the inner wall of the socket, penetrating both sides of the external force contact plates, to allow rotation of the external force contact plates. A fixing block is connected to the inner side of the end of the external force contact plate. Fixing slots that match the fixing blocks are opened on both sides of the socket. In this utility model, when the plug is inserted, the external force contact plates drive the fixing blocks to slide on the inclined surface and press their bottom ends to rotate away from the socket. When the external force contact plates rotate, they compress a first spring strip. When the external force contact plates drive the fixing blocks downwards to one side of the fixing slot, the first spring strip presses the external force contact plates to rotate in the opposite direction. After the external force contact plates return to their original position, they drive the end of the fixing blocks to insert into the fixing slot, achieving quick and convenient locking between the plug and socket.

Description

Technical Field

[0001] This utility model belongs to the field of docking plug technology, specifically relating to a quick docking plug with a convenient locking structure. Background Technology

[0002] Quick-connect plugs, also known as quick-connectors, are tool-free connectors that allow for the connection or disconnection of conduits. They are designed to simplify the connection process, reduce insertion and removal time, and provide reliable connections. Quick-connect plugs typically consist of a plug and a socket. The plug usually has guide pins, grooves, or slots to ensure accurate insertion into the socket; the socket includes pinholes, contact pieces, and a housing.

[0003] Quick-connect plugs achieve connection and disconnection through the mating of a plug and a socket. Both the plug and socket have specific shapes and guide structures to ensure proper alignment and connection. There are typically multiple metal contact points between the plug and socket of the connector for transmitting signals, power, or data. These contact points are usually metallic conductors, such as copper, gold, or silver-plated metals, to ensure good conductivity.

[0004] To ensure stable and safe power transmission and prevent loosening or complete detachment of plugs and sockets due to external forces during daily use, existing sockets and plugs typically require an additional locking mechanism during connection. However, current market-standard locking mechanisms often use bolts, which are complex to operate and require more time to lock and release, causing considerable inconvenience to users. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-connect plug with a convenient locking structure, which aims to solve the problem that the locking structure in the prior art usually uses bolts for fixing, which is very complicated to operate during use, and thus requires more time to lock and release the socket and plug, causing a lot of trouble for users.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-connect plug with a convenient locking structure, including a socket and a matching plug. A conductive base is installed inside the plug. External force contact plates are fitted on both sides of the socket. A first horizontal axis is connected to the inner wall of the socket through both sides of the external force contact plates to realize the rotation of the external force contact plates. A fixing block is connected to the inner side of the end of the external force contact plate. Fixing slots that match the fixing blocks are opened on both sides of the socket. A first spring strip connected to the side surface of the plug is connected to the inner wall of the external force contact plate.

[0007] As a preferred embodiment of the quick-connect plug with a convenient locking structure of the present invention, the socket has inclined surfaces on both sides, and the width of the inclined surfaces is greater than the width of the fixing block, and the side surface of the fixing block is set as an inclined surface.

[0008] As a preferred embodiment of the quick-connect plug with a convenient locking structure of this utility model, when the first spring strip is in a balanced state by the external force pressing the contact plate, the end of the fixing block is inserted into the inside of the fixing slot.

[0009] As a preferred embodiment of the quick-connect plug with a convenient locking structure of the present invention, a connecting block is connected to the inner wall of the plug interface of the conductive base, a rotating component is connected to the surface of the connecting block, and a protective plate is connected to the surface of the rotating component.

[0010] As a preferred embodiment of the quick-connect plug with a convenient locking structure of this utility model, the conductive base, connecting block, rotating assembly and protective plate are symmetrically arranged on both sides of the inner wall of the plug interface of the conductive base.

[0011] As a preferred embodiment of the quick-connect plug with a convenient locking structure of this utility model, the cross-sectional dimensions of the two protective plates, when not under stress, are adapted to the cross-sectional dimensions of the inner wall of the conductive base's insertion interface.

[0012] As a preferred embodiment of the quick-connect plug with a convenient locking structure of this utility model, the rotating assembly includes a support plate, a second horizontal shaft, and a second spring strip. Two support plates are connected to the surface of each protective plate, and the two support plates are located on both sides of the connecting block. A second horizontal shaft penetrating the interior of the support plate is connected to each side of the connecting block, and a second spring strip connected to the support plate is connected to each side of the connecting block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, when the plug is inserted into the socket, the external force contact plate drives the fixing block to slide on the surface of the inclined surface. The fixing block is squeezed by the inclined surface, causing the bottom end of the external force contact plate to rotate away from the socket and compress the first spring strip. When the plug drives the external force contact plate downward and moves the fixing block to one side of the fixing slot, the first spring strip squeezes the external force contact plate to rotate in the opposite direction through its own elasticity. After the external force contact plate resets, it drives the end of the fixing block to be inserted into the fixing slot, thereby realizing quick and convenient locking between the plug and the socket.

[0015] In this invention, when the plug and socket are inserted, the protective plate inside the conductive base is squeezed by the pin. When the protective plate is squeezed, it rotates through the setting of the rotating component. After the plug is unplugged, the protective plate can be reset through the setting of the rotating component. Thus, the protective plate protects the inner wall of the conductive base interface and prevents dust from entering the conductive base and affecting the conductivity. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-8 The present invention provides the following technical solution: a quick-connect plug with a convenient locking structure, including a socket 1 and a matching plug 2. A conductive base 9 is installed inside the plug 2. External force contact plates 3 are fitted on both sides of the socket 1. A first horizontal shaft 4 is connected to the inner wall of the socket 1 through both sides of the external force contact plates 3 to realize the rotation of the external force contact plates 3. A fixing block 5 is connected to the inner side of the end of the external force contact plate 3. Fixing slots 7 that are adapted to the fixing blocks 5 are opened on both sides of the socket 1. A first spring strip 6 connected to the side surface of the plug 2 is connected to the inner wall of the external force contact plate 3.

[0028] Preferably, the socket 1 has inclined surfaces 8 on both sides, and the width of the inclined surfaces 8 is greater than the width of the fixing block 5, and the side surface of the fixing block 5 is set as an inclined surface.

[0029] In actual use, during the process of plug 2 being inserted into socket 1, socket 1 drives fixed block 5 to slide on the surface of inclined surface 8 through external force contact plate 3. Fixed block 5 is squeezed by inclined surface 8, which can drive the bottom end of external force contact plate 3 to rotate away from socket 1 with the center line of the first horizontal axis 4 as the center.

[0030] Preferably, when the first spring bar 6 is in a balanced state by the elastic force pressing the external force contacting the plate 3, the end of the fixing block 5 is inserted into the inside of the fixing slot 7.

[0031] In practical use, when the external force contact plate 3 drives the fixed block 5 to move to one side of the fixed slot 7, the first spring strip 6 squeezes the external force contact plate 3 with elastic force. The external force contact plate 3 is squeezed and rotates, causing the end of the fixed block 5 to be inserted into the fixed slot 7, thereby achieving the locking between the plug 2 and the socket 1.

[0032] Preferably, the inner wall of the insertion interface of the conductive base 9 is connected to a connecting block 10, the surface of the connecting block 10 is connected to a rotating component 11, and the surface of the rotating component 11 is connected to a protective plate 12.

[0033] In actual use, when the plug 2 is plugged into the socket 1, the protective plate 12 inside the conductive base 9 is squeezed by the pin and rotated by the rotating component 11. After the plug 2 is unplugged, the protective plate 12 can be reset by the rotating component 11.

[0034] Preferably, the conductive base 9, the connecting block 10, the rotating component 11, and the protective plate 12 are symmetrically arranged on both sides of the inner wall of the insertion interface of the conductive base 9.

[0035] Preferably, the cross-sectional dimensions of the two protective plates 12 forming a whole under no-stress conditions are adapted to the cross-sectional dimensions of the inner wall of the insertion interface of the conductive base 9.

[0036] In practical use, the protective plate 12 is in a horizontal state under the elastic force of the second spring strip 1103. At this time, the two protective plates 12 can block the insertion interface of the conductive base 9, thereby preventing dust from entering the interior of the conductive base 9.

[0037] Preferably, the rotating assembly 11 includes a support plate 1101, a second horizontal shaft 1102, and a second spring strip 1103. Two support plates 1101 are connected to the surface of each protective plate 12, and the two support plates 1101 are located on both sides of the connecting block 10. A second horizontal shaft 1102 that penetrates the interior of the support plate 1101 is connected to each side of the connecting block 10. A second spring strip 1103 that is connected to the support plate 1101 is connected to each side of the connecting block 10.

[0038] In practical use, when the protective plate 12 is subjected to a force, it can drive the support plate 1101 to rotate on the surface of the second horizontal shaft 1102. When the support plate 1101 rotates, it can drive the second spring strip 1103 to deform. When the force disappears, the second spring strip 1103 drives the support plate 1101 and the protective plate 12 to reset through its own elasticity.

[0039] Working principle: When plug 2 is inserted into socket 1, the external force contact plate 3 drives the fixing block 5 to slide on the surface of inclined surface 8. The fixing block 5 is squeezed by inclined surface 8, which drives the bottom end of external force contact plate 3 to rotate away from socket 1 and compress the first spring strip 6. When plug 2 drives external force contact plate 3 to move downward and drives fixing block 5 to one side of fixing slot 7, the first spring strip 6 squeezes external force contact plate 3 to rotate in the opposite direction through its own elasticity. After external force contact plate 3 is reset, it drives the end of fixing block 5 to be inserted into fixing slot 7, thereby locking plug 2 and socket 1. When plug 2 and socket 1 need to be separated, the upper end of external force contact plate 3 can be squeezed. When external force contact plate 3 is squeezed, its bottom end can rotate away from socket 1. When external force contact plate 3 drives fixing block 5 to move to the outside of fixing slot 7, plug 2 can be pulled out.

[0040] During the insertion of plug 2 into socket 1, when the protective plate 12 inside conductive base 9 is squeezed by the pin, it causes the support plate 1101 to rotate on the surface of the second horizontal shaft 1102 and causes the second spring strip 1103 to deform. When plug 2 is pulled out from inside socket 1, the second spring strip 1103 drives the support plate 1101 to reset through its own elasticity. The reset of the support plate 1101 can drive the protective plate 12, thereby protecting the inner wall of the conductive base 9 insertion interface through the two protective plates 12.

[0041] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
