Description
Technical Field
[0001] The present application relates to the technical field of socket connection devices, and in particular to a secondary lock structure of a socket. Background Art
[0002] In daily life, the connection ports of circuit transmission lines are usually connected by a plug and a socket base. In order to ensure the stability of the connection between the plug and the base, a locking mechanism is installed between the plug and the base for fixing.
[0003] Most locking mechanisms are usually fixed in the form of a buckle, but during the use of the buckle, the range of movement of the buckle is not restricted, the buckle is easily unlocked by accidental pressure, and the stability performance when fixed is not high, which can easily cause the plug to separate from the base during use of the socket, causing a safety accident. Utility Model Content
[0004] In order to improve the convenience of the secondary lock structure of the socket during operation, the present application provides a secondary lock structure of the socket.
[0005] The present application provides a secondary lock structure of a socket, which adopts the following technical solution:
[0006] A secondary locking structure of a socket comprises a base, on which a first locking structure for initial position limiting is installed, the first locking structure comprises a mounting frame, the mounting frame is installed on the base, a second locking structure for secondary position limiting is connected to the mounting frame, the second locking structure comprises a support rod, the support rod is installed on the mounting frame, a locking plate for fixing is installed on the mounting frame; a sliding groove is provided on the mounting frame, a push block for limiting the locking plate is slidably installed on the mounting frame through the sliding groove, and a plug is detachably installed on the base through the first locking structure and the second locking structure.
[0007] By adopting the above technical solution, after the first limiting fixation is performed by the first locking structure, the plug is then limited and fixed for the second time by the second locking structure. The double locking and fixing strengthens the fixing effect of the plug and enhances the stability of the connection between the plug and the base. The lock plate is then limited and fixed by the push block to prevent the plug from being unlocked due to accidental pressing of the lock plate during use, thereby enhancing the locking stability between the lock plate and the plug and helping to enhance the safety of the socket during use.
[0008] In a specific possible implementation manner, a second pressing platform is installed on the locking plate, and a pressing surface abutting against the second pressing platform is provided on the pushing block.
[0009] By adopting the above technical solution, installing the second pressing platform facilitates pressing down the lock plate to quickly unlock the plug, and at the same time, using the push block to press against the second pressing platform is simple and convenient, and the lock plate can be quickly locked and unlocked.
[0010] In a specific possible implementation scheme, a lock slot is provided on the lock plate, a second fixing block is mounted on the plug to limit the lock plate, and a side of the second fixing block close to the lock plate is configured as a beveled surface.
[0011] By adopting the above technical solution, after the second fixing block contacts the locking plate, the end of the locking plate in contact with the second fixing block is lifted upward by the action of the inclined surface until the second fixing block falls into the locking groove, thereby facilitating quick fixing of the plug.
[0012] In a specific feasible implementation scheme, a limiting rod is connected to the push block, a protrusion is installed at one end of the limiting rod close to the plug, and the side of the protrusion close to the plug is set as an arc surface; a first limiting block is installed on the limiting rod, a second limiting block abutting against the first limiting block is installed on the base, a top block for pushing the limiting rod to lift is installed on the plug, the top block is arranged on a side of the second fixed block close to the push block, and the side of the top block close to the push block and the side away from the push block are both set as chamfered surfaces.
[0013] By adopting the above technical solution, when the second fixed block pushes the locking plate, the top block contacts the protrusion and pushes the protrusion to move upward. The upward movement of the protrusion drives the limit rod to lift upward, thereby driving the first limit block to move upward and away from the second limit block. Only then is the push block activated, and the push block can move on the mounting frame to fix the lock plate, reducing the influence of the limit rod on the insertion of the plug into the base, and preventing the situation where the push block is in a state of fixing the lock plate when the plug is inserted into the base, and the second fixed block cannot push up the lock plate.
[0014] In a specific implementation scheme, the first locking structure also includes a locking plate, a first locking buckle is installed on one end of the locking plate close to the plug, a mounting plate is installed on the plug, a first fixing block is installed on the mounting plate, and a side of the first locking buckle close to the first fixing block is set as a bevel surface.
[0015] By adopting the above technical solution, the first fixed block squeezes the first lock buckle, and through the action of the inclined surface on the first lock buckle, the first fixed block pushes the first lock buckle to move upward. When the first fixed block moves completely through the first lock buckle, the locking plate returns to its position and presses the first lock buckle downward to the rear of the first fixed block. At this time, the vertical side wall of the first fixed block is against the vertical side wall of the first lock buckle, preventing the plug from detaching from the base during use, thereby enhancing the safety performance of the socket.
[0016] In a specific possible implementation manner, a first pressing platform is installed on an end of the locking plate away from the first locking buckle.
[0017] By adopting the above technical solution, when it is necessary to remove the plug, press the first pressing platform downward to rotate the locking plate installed at one end of the first locking buckle upward. After the first locking buckle moves to the top of the first fixed block, pull out the plug, and press one end of the locking plate to lower it so that the other end of the locking plate rises, thereby facilitating the detachable installation of the plug.
[0018] In summary, the present application includes at least one of the following beneficial technical effects:
[0019] 1. After the first limit fixation by the first locking structure, the second limit fixation of the plug is performed by the second locking structure. The double locking and fixation strengthens the fixing effect of the plug and enhances the stability of the connection between the plug and the base. The lock plate is then limited by the push block to fix the lock plate to prevent the plug from being unlocked due to accidental pressing of the lock plate during use, thereby enhancing the locking stability between the lock plate and the plug and helping to enhance the safety of the socket during use.
[0020] 2. Through the setting of the first locking structure, the first fixed block squeezes the first lock buckle, and through the action of the inclined surface on the first lock buckle, the first fixed block pushes the first lock buckle to move upward. When the first fixed block moves completely through the first lock buckle, the locking plate returns to its position and presses the first lock buckle downward to the rear of the first fixed block. At this time, the vertical side wall of the first fixed block is against the vertical side wall of the first lock buckle, preventing the plug from detaching from the base during use, thereby enhancing the safety performance of the socket.

DETAILED DESCRIPTION
[0028] The following is combined with Figure 1-6 This application is described in further detail.
[0029] Example:
[0030] The present application embodiment discloses a secondary lock structure of a socket, referring to Figure 1 , including a base 1, on which is mounted a first locking structure 2 for primary limiting, to which is connected a second locking structure 3 for secondary locking, and a plug 4 is detachably mounted on the base 1 via the first locking structure 2 and the second locking structure 3.
[0031] The plug 4 is inserted into the base 1, and after the first limit fixation is performed by the first locking structure 2, the plug 4 is then limited and fixed for the second time by the second locking structure 3. The double locking and fixing strengthens the fixing effect of the plug 4, enhances the stability of the connection between the plug 4 and the base 1, and is beneficial to improving the safety effect of the socket during use.
[0032] Reference Figure 1 and Figure 2 The first locking structure 2 includes a mounting frame 21, which is fixedly mounted on the base 1. A locking plate 22 is fixedly mounted on the mounting frame 21. The connection position between the mounting frame 21 and the locking plate 22 is located in the middle of the length direction of the locking plate 22. There is a gap between the two ends of the locking plate 22 and the mounting frame 21. A first locking buckle 23 is fixedly mounted on the locking plate 22. A chamfered surface is provided on the side of the first locking buckle 23 close to the plug 4. A mounting plate 24 is fixedly mounted on the plug 4. A first fixing block 25 fixed to the mounting plate 24 is fixedly mounted to fix the first locking buckle 23. A first pressing platform 26 is fixedly mounted on the end of the locking plate 22 away from the first fixing block 25. The horizontal plane height of the first pressing platform 26 is higher than the horizontal plane height of the mounting frame 21.
[0033] When the plug 4 is inserted into the base 1, the first fixed block 25 squeezes the first lock buckle 23. Through the action of the inclined surface on the first lock buckle 23, the first fixed block 25 pushes the first lock buckle 23 to move upward, and the first lock buckle 23 pushes the lock plate 22 to swing upward. When the first fixed block 25 moves to completely pass the first lock buckle 23, the lock plate 22 returns to press the first lock buckle 23 downward to the rear of the first fixed block 25. At this time, the vertical side wall of the first fixed block 25 and the vertical side wall of the first lock buckle 23 are against each other, limiting the first fixed block 25 to prevent the plug 4 from being separated from the base 1 during use, thereby enhancing the safety performance of the socket. When it is necessary to remove the plug, the first pressing platform 26 is pressed downward to rotate the lock plate 22 installed at one end of the first lock buckle 23 upward. After the first lock buckle 23 moves to the top of the first fixed block 25, the plug 4 is pulled out, and the other end of the lock plate 22 is raised by pressing one end of the lock plate 22 to facilitate the detachable installation of the plug 4.
[0034] Reference Figure 2 and Figure 3 The second locking structure 3 includes a support rod 31, which is fixedly mounted on the mounting frame 21, and a locking plate 32 is fixedly mounted on the support rod 31. The connection position between the support rod 31 and the mounting frame 21 is located in the middle position in the length direction of the mounting frame 21. A locking groove 321 is provided on the locking plate 32, and a second pressing platform 322 is fixedly mounted on the end of the locking plate 32 away from the plug 4. A second fixing block 33 fixed to the locking plate 32 is fixedly mounted on the plug 4, and a side of the second fixing block 33 close to the locking plate 32 is set as a beveled surface.
[0035] Reference Figure 2 and Figure 4 A slide groove 211 is provided on the mounting frame 21, and a push block 34 is slidably installed on the mounting frame 21 through the slide groove 211. The push block 34 is provided with a tight table surface 341 that abuts against the second pressing table 322. A limit rod 342 is fixedly installed on the push block 34, and the limit rod 342 is arranged below the lock plate 32. A protrusion 343 is fixedly installed on the end of the limit rod 342 away from the push block 34, and the side of the protrusion 343 away from the push block 34 is set as an arc surface, and a top block 35 that pushes the limit rod 342 to move is fixedly installed on the plug 4. The top block 35 is arranged on a side of the second fixed block 33 close to the push block 34, and the side of the top block 35 close to the second fixed block 33 and the side away from the second fixed block 33 are both set as chamfered surfaces. A first limit block 344 is fixedly installed on the bottom surface of the limit rod 342 close to the base 1, and the side of the first limit block 344 away from the protrusion 343 is set as a bevel surface. A second limit block 345 is fixedly installed on the base 1 to cooperate with the first limit block 344 for limiting, and the side of the second limit block 345 close to the protrusion 343 is set as a bevel surface.
[0036] Reference Figure 2 , Figure 5 and Figure 6 , Figure 2 This is a state diagram before the plug 4 is pushed into the base 1. Figure 5 This is a state diagram of the lock plate 32 fixing the second fixing block 33 when the plug 4 is just inserted into the base 1. Figure 6 The state diagram of the locking plate 32 fixed by the limiting rod 342, when the plug 4 is pushed into the base 1, after the first fixing block 25 passes through the first locking buckle 23 for the first time, the plug 4 is pushed into the base 1, and the second fixing block 33 abuts against the locking plate 32. Through the action of the inclined surface of the second fixing block 33, the second fixing block 33 pushes the end of the locking plate 32 close to the second fixing block 33 to move upward. When the second fixing block 33 passes through the locking plate 32 and moves to the bottom of the locking groove 321, the end of the locking plate 32 close to the second fixing block 33 moves downward so that the vertical side wall of the locking plate 32 and the vertical side wall of the second fixing block 33 reach the fixing effect of the locking plate 32. At this time, the plug 4 is just completely inserted into the base 1. If it is necessary to unlock the second fixing block 33, press the second pressing platform 322 downward to lift the end of the locking plate 32 close to the second fixing block 33 upward. After the locking plate 32 is separated from the second fixing block 33, the plug 4 is pulled out, which is convenient for quickly unlocking the plug 4.
[0037] In order to reduce the influence of the limit rod 342 on the plug 4 when being inserted into the base 1, the limit rod 342 is as follows when not in use. Figure 2 In the state shown, the first limit block 344 is in contact with the second limit block 345. When the second fixing block 33 pushes the locking plate 32, the top block 35 contacts the protrusion 343 and pushes the protrusion 343 to move upward. The upward movement of the protrusion 343 drives the limit rod 342 to lift upward, thereby driving the first limit block 344 to move upward away from the second limit block 345. Figure 5 As shown, when the second fixing block 33 just moves to the point where the locking plate 32 can move downward to fix the second fixing block 33 , the top block 35 just pushes the limiting rod 342 to make the first limiting block 344 disengage from the second limiting block 345 , thereby activating the push block 34 .
[0038] When the locking cam 33 is in the unlocking state, the locking cam 332 is in the unlocking state, and the locking cam 332 is in the unlocking state, so that the locking cam 332 is locked and the locking cam 332 is locked.
[0039] When the lock plate 32 needs to be unlocked, the push block 34 is dragged away from the lock plate 32. Through the action of the inclined surface of the top block 35 close to the second fixed block 33, the limit rod 342 is lifted up close to the second fixed block 33. When the protrusion 343 leaves the top block 35, the first limit block 344 abuts against the second limit block 345 again, blocking the push block 34 from moving, thereby facilitating the quick unlocking of the lock plate 32.
[0040] The implementation principle of the embodiment of the present application is as follows: the plug 4 is inserted into the base 1, and after the first limiting fixation is performed by the first locking structure 2, the plug 4 is then limited and fixed for the second time by the second locking structure 3. The double locking and fixing strengthens the fixing effect of the plug 4, and moves the abutting table surface 341 of the push block 34 to the bottom of the second pressing table 322 and abuts against the second pressing table 322, thereby blocking the end of the second pressing table 322 installed on the lock plate 32 from swinging downward, preventing the plug 4 from being accidentally pressed on the second pressing table 322 during use, causing the lock plate 32 near the end of the second fixing block 33 to lift up and unlock the plug 4, thereby increasing the stability of the lock plate 32 locking the plug 4, enhancing the stability of the connection between the plug 4 and the base 1, and helping to improve the safety of the socket during use.
[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
