Description

Technical Field

[0001] This invention belongs to the field of plug and socket technology, specifically, it relates to an anti-loosening socket and its usage method. Background Technology

[0002] Currently, industrial and residential power plugs and sockets use a metal contact type. When the plug is inserted into the socket, the metal contact of the plug makes contact with the energized metal contact on the socket side, thus energizing the plug side. This type of power socket and plug connection structure is simple and widely used.

[0003] Existing socket structures all use an interference fit between the plug prongs and the socket sleeve. This method utilizes the spring-loaded properties of the socket sleeve's metal plate and friction to ensure the power connection between the plug prongs and the socket sleeve. However, this method has a drawback: during prolonged use or under high-power loads, the metal plate of the socket sleeve is prone to deformation, leading to poor contact between the plug prongs and the socket sleeve, sparking, power outages, and plug loosening, posing electrical safety hazards. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-loosening socket and its usage method, mainly to solve the problems that existing socket structures are prone to deformation of the metal plate of the socket sleeve during long-term use or under high power load, resulting in poor contact between the plug and the socket sleeve, arcing, power failure, and plug loosening.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] An anti-loosening socket includes a base with a central receiving space, a plug sliding cover installed in the receiving space and engaged at the bottom by a compression spring, a locking mechanism disposed on the plug sliding cover for locking the plug ground wire prong of the socket, and a release mechanism disposed on the base for engaging with the plug sliding cover to unlock the plug ground wire prong.

[0007] Furthermore, in this invention, the base includes an upper base cover and a lower base cover connected by screws, a positioning groove provided in the middle of the lower base cover for limiting the lower end of the compression spring, and a fixing groove provided on the upper base cover for installing the release mechanism.

[0008] Furthermore, in this invention, the sliding cover includes a sliding lower cover and a sliding upper cover that interlock with each other, a sleeve ring wall disposed on the back of the sliding lower cover for limiting the upper end of the compression spring, a live wire socket, a neutral wire socket and a ground wire socket disposed on the front of the sliding lower cover, a live wire socket, a neutral wire socket and a ground wire socket disposed on the top surface of the sliding upper cover and corresponding to the positions of the live wire socket, the neutral wire socket and the ground wire socket, a locking mechanism mounting hole disposed on both sides of the sliding upper cover and aligned with the ground wire socket, and a sliding upper cover locking buckle disposed on the front side of the sliding upper cover for engaging with the release mechanism.

[0009] Furthermore, in this invention, the locking mechanism is composed of a left pressing mechanism and a right pressing mechanism that are identical in structure and symmetrical to each other. The left pressing mechanism is composed of a pre-pressing protrusion, a pre-pressing spring, and a pre-pressing silicone head. The pre-pressing protrusion is an L-shaped structure composed of a vertical plate and a horizontal rod. The lower end of the vertical plate is rotatably connected to the inner wall of the sliding cover. The upper end of the vertical plate is provided with a protrusion on the side of the sliding cover where the locking mechanism mounting hole is located, which protrudes outward. The end of the horizontal rod away from the vertical plate is engaged by a mounting slot installed on the top wall of the sliding cover. The pre-pressing spring is sleeved on the section of the horizontal rod located between the mounting slot and the vertical plate. The pre-pressing silicone head is connected to the end of the horizontal rod away from the vertical plate and is located on the other side of the mounting slot relative to the pre-pressing spring.

[0010] Furthermore, in this invention, the inner wall of the sliding cover is provided with a pivot mounting groove, and the lower ends of the vertical plate of the pre-pressed protrusion are provided with pivots that are rotatably connected to the pivot mounting groove.

[0011] Furthermore, in this invention, the release mechanism includes a release button that is mounted in the fixing groove by a release button spring, and a release button boss disposed on one side of the release button for cooperating with the sliding cover locking buckle.

[0012] Furthermore, in this invention, the lower end of the sliding cover is provided with a limiting step to prevent the sliding cover from sliding out of the receiving space of the base.

[0013] Based on the above-mentioned anti-loosening socket, the present invention also provides a method for using the anti-loosening socket, comprising the following steps:

[0014] When the plug is inserted into the anti-loosening socket, under the action of the compression spring, the corresponding prong of the plug first inserts into the corresponding socket. At this time, the sliding cover is not sunk into the base and is in a raised state, and the sliding cover locking buckle is in a disengaged state; the pre-compression spring and the pre-compression protrusion are in a free state; the pre-compression silicone head does not touch or press against the ground wire prong of the plug; when the plug is further inserted, the compression spring is further compressed, and the entire mechanism of the socket sliding cover is sunk into the base; the sliding cover locking buckle on the sliding cover is engaged in the base; at the same time, the pre-compression protrusions on both sides are pressed by the side wall of the base cover, and the lower end of the vertical plate of the pre-compression protrusion rotates through the pivot, causing the horizontal rod at the upper end to drive the pre-compression silicone heads on both sides to move towards the ground wire prong and press and lock the ground wire prong. At this time, the pre-compression spring is in a compressed state, thus completing the power supply of the anti-loosening socket;

[0015] When you are finished using the power and need to unplug the plug, simply press the release button. The release button protrusion will move downwards, pushing open the sliding cover and locking the sliding cover. The entire mechanism of the plug sleeve sliding cover will be pushed out of the base and return to its original state under the action of the compression spring. At this time, the plug can be unplugged normally.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention features an ingenious structural design. By incorporating a sliding cover with a slidable connection within the base and a locking mechanism on the sliding cover, the plug insertion process is identical to that of a conventional plug insertion. However, during plug insertion, the plug prongs first insert into the socket under the action of a compression spring. At this point, the sliding cover is not recessed into the base but remains protruding. The sliding cover locking buckle is disengaged. The pre-compression spring and pre-compression protrusions are in a free state. The pre-compression silicone head does not contact or press against the grounding prong of the plug. When the plug is further inserted, the compression spring is further compressed, and the entire sliding cover mechanism retracts into the base. The sliding cover locking buckle engages with the base. Simultaneously, the pre-compression protrusions on both sides are pressed by the base sidewalls, causing the pre-compression silicone heads on both sides to move towards the grounding prong and press and lock it in place. At this point, the pre-compression spring is compressed. This completes the power supply function of the anti-loosening socket, preventing the plug and socket from slipping out of the socket during use, thus improving safety. When you are finished using the power and need to unplug the socket, simply press the trip button. The protrusion of the trip button will move downwards, pushing open the sliding cover and locking it. Under the return force of the compression spring, the entire mechanism of the socket sliding cover will be pushed out of the base and return to its original position. At this point, the plug can be unplugged normally. The operation is simple and convenient. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0026] like Figures 1-4 As shown, the present invention discloses an anti-loosening socket, including a base with a accommodating space 1 in the middle, a plug sliding cover installed in the accommodating space 1 and engaged at the bottom by a compression spring 2, a locking mechanism disposed on the plug sliding cover for locking the plug ground wire prong of the socket, and a release mechanism disposed on the base for engaging with the plug sliding cover to unlock the plug ground wire prong.

[0027] In this embodiment, the base includes an upper base cover 3 and a lower base cover 4 connected by screws, a positioning groove 5 located in the middle of the lower base cover 4 for limiting the lower end of the compression spring 2, and a fixing groove 6 on the upper base cover 3 for installing a release mechanism. The release mechanism includes a release button 28 mounted in the fixing groove 6 via a release button spring 27, and a release button protrusion 29 located on one side of the release button 28 for engaging with the sliding upper cover locking buckle 17. When the plug needs to be unplugged after power consumption, simply press the release button 28. The release button protrusion 29 moves downward, pushing open the sliding upper cover locking buckle 17 on the sliding upper cover 8. Under the recoil force of the compression spring 2, the entire sliding cover mechanism is pushed out of the base and into the... Figure 2 Status. The plug can now be unplugged normally.

[0028] In this embodiment, the sliding cover includes a sliding lower cover 7 and a sliding upper cover 8 that interlock with each other; a connecting ring wall 9 disposed on the back of the sliding lower cover 7 for limiting the upper end of the compression spring 2; a live wire socket 10, a neutral wire socket 11, and a ground wire socket 12 disposed on the front of the sliding lower cover 7; a live wire socket 13, a neutral wire socket 14, and a ground wire socket 15 that are opened through the top surface of the sliding upper cover 8 and correspond to the positions of the live wire socket 10, the neutral wire socket 11, and the ground wire socket 12; locking mechanism mounting holes 16 opened on both sides of the sliding upper cover 8 and aligned with the ground wire socket 15; and a sliding upper cover locking buckle 17 disposed on the front side of the sliding upper cover 8 for engaging with the release mechanism. The positioning groove 5 and the connecting ring wall 9 enable the positioning and installation of the compression spring, meaning that the lower outer wall of the compression spring is completely confined within the positioning groove 5, and the upper inner wall of the compression spring is sleeved on the connecting ring wall 9. When the plug is inserted, the ground wire prong 28, the live wire prong 29, and the neutral wire prong 30 of the plug 27 are respectively inserted into the ground wire socket 12, the live wire socket 10, and the neutral wire socket through the ground wire socket 15, the live wire socket 13, and the neutral wire socket 14.

[0029] In this embodiment, the locking mechanism consists of a left compression mechanism and a right compression mechanism that are identical in structure and symmetrical to each other. The left compression mechanism consists of a pre-compression protrusion 18, a pre-compression spring 19, and a pre-compression silicone head 20. The pre-compression protrusion 18 is an L-shaped structure consisting of a vertical plate 21 and a horizontal rod 22. The lower end of the vertical plate 21 is rotatably connected to the inner wall of the sliding cover 8. The upper end of the vertical plate 21 is provided with a protrusion 23 on the side of the sliding cover 8 where the locking mechanism mounting hole 16 is located, which protrudes outward. The end of the horizontal rod 22 away from the vertical plate 21 is engaged by a mounting slot 24 installed on the top wall of the sliding cover 8. The pre-compression spring 19 is sleeved on the section of the horizontal rod located between the mounting slot 24 and the vertical plate 21. The pre-compression silicone head 20 is connected to the end of the horizontal rod away from the vertical plate 21 and is located on the other side of the mounting slot 24 relative to the pre-compression spring 19. When the plug is inserted into the sliding cover 8, under the action of the compression spring 2, the plug prongs first insert into the socket. At this time, the sliding cover 8 is not recessed into the base, and the entire base is in a raised state. The sliding cover locking buckle 17 is in a disengaged state. The pre-compression spring 19 and the pre-compression protrusion 18 are in a free state. The pre-compression silicone head 20 does not touch or press against the ground wire prong 34 of the plug (e.g., Figure 2 (As shown). When the plug is further inserted, the compression spring 2 is further compressed. The sliding cover 8 and the entire mechanism assembly sink into the base. The sliding cover locking buckle 17 on the sliding cover 8 is engaged in the base 3. At the same time, the pre-compression protrusions 17 on both sides are pressed by the side wall of the base, and the lower end of the vertical plate 21 of the pre-compression protrusion 17 rotates through the pivot, causing the horizontal rod 22 at the upper end to drive the pre-compression silicone heads 20 on both sides to move towards the ground wire plug 24 and press and lock the ground wire plug. At this time, the pre-compression spring 19 is in a compressed state, thus completing the power supply of the anti-loosening socket.

[0030] In this embodiment, the lower end of the sliding cover 8 is provided with a limiting step 30 to prevent the sliding cover 8 from sliding out of the receiving space 1 of the base. The limiting step 30 extends horizontally from the lower end of the sliding cover 8, so that the lower end of the sliding cover 8 is larger than the receiving groove, thereby completely limiting the entire plug sliding cover within the receiving space 1 of the base, preventing the plug sliding cover from being completely pulled out of the base when the plug is inserted or removed.

[0031] Through the above design, this invention adds an anti-disengagement locking mechanism to the existing socket, ensuring a good connection between the plug and the socket during power use. Simultaneously, by incorporating a release button, simply pressing this button releases the locking mechanism when the plug is unplugged, allowing for normal unplugging. This design is simple in structure and highly versatile. It is suitable for use with various fixed or portable sockets and plays a positive role in optimizing and promoting electrical safety.

[0032] The above embodiments are merely one of the preferred embodiments of the present invention and should not be used to limit the scope of protection of the present invention. Any modifications or refinements made to the main design concept and spirit of the present invention that are not of substantial significance, but solve the same technical problem as the present invention, should be included within the scope of protection of the present invention.
