Description
Technical Field
[0001] This utility model relates to the field of waterproof plug technology, specifically a waterproof plug with an anti-detachment structure. Background Technology
[0002] Waterproof plugs are plugs or connectors with waterproof properties that provide safe and reliable electrical and signal connections. They have a wide range of applications, including LED streetlights, LED driver power supplies, LED displays, lighthouses, cruise ships, industrial equipment, communication equipment, detection equipment, commercial plazas, highways, villa exteriors, gardens, parks, and other scenarios.
[0003] Existing waterproof plugs have poor connection stability when male and female are connected, relying on simple plugging and unplugging. They lack a stable structure and are prone to loosening and falling off due to external force, vibration or long-term use. Furthermore, there are no secondary fixing measures to ensure the connection, making it difficult for existing waterproof plugs to meet actual needs in terms of reliability, durability and ease of use.
[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on the existing waterproof inserts with anti-detachment structures. Utility Model Content
[0005] The purpose of this utility model is to provide a waterproof plug with an anti-detachment structure to solve the problems mentioned in the background art, such as poor connection stability of the male and female plugs when connected, reliance on simple plugging and unplugging, lack of a stable structure, easy loosening and detachment due to external force, vibration or long-term use, and lack of secondary fixing measures to ensure connection, which makes it difficult for existing waterproof plugs to meet actual needs in terms of reliability, durability and ease of use.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof plug with an anti-detachment structure, comprising a male plug and a female plug, wherein the female plug is movably abutted against the interior of the male plug, and a fixing plate is installed on the side of the male plug away from the female plug; a sliding rod is slidably connected around the fixing plate, a limit block is provided at one end of the sliding rod, and a moving block is fixedly connected to the other end of the sliding rod; a wire groove is opened on one side of the moving block, and the cable end of the female plug is slidably connected to the interior of the wire groove; an anti-detachment mechanism for preventing the female plug from detaching is provided on the moving block.
[0007] Furthermore, the anti-detachment mechanism includes a locking block, which is fixedly connected to both ends of the fixed plate near the moving block. The locking block is provided with a locking groove, and a wedge block is slidably connected inside the moving block. The contact surfaces of the locking block and the wedge block are complementary inclined surfaces.
[0008] Furthermore, a movable plate is installed on one side of the two wedge blocks that are close to each other. The movable plate is slidably connected to the inside of the movable block. A spring is installed on one side of the two movable plates that are close to each other. The top of the spring is installed inside the movable block. The wedge blocks are movably engaged inside the slot.
[0009] Furthermore, the movable block is provided with a fixing mechanism for assisting in fixing the end of the female plug cable. The fixing mechanism includes a first closing plate and a second closing plate. The first closing plate and the second closing plate are slidably connected inside the movable block and abut against each other. A sliding block is installed on one side of each of the first closing plate and the second closing plate.
[0010] Furthermore, a movable seat is installed on the other side of both the first and second closing plates, and a bidirectional lead screw is rotatably connected to one side inside the movable block, with the outer wall of the bidirectional lead screw threadedly connected to the movable seat.
[0011] Furthermore, the first and second closing plates are provided with annular grooves that match the female plug, and a sealing gasket is installed at the bottom of the first closing plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This waterproof connector with an anti-detachment structure works by moving a movable block after the male and female connectors are joined, causing a locking block to engage with a wedge-shaped block. The inclined surface of the wedge-shaped block presses against the locking block, compressing a spring. Once the wedge-shaped block's groove aligns with the locking block's position, the spring returns to its original position, allowing the locking block to engage in the groove. This secures the fixed block and the movable block, effectively preventing the female connector from accidentally detaching, ensuring the stability and reliability of the connection, and guaranteeing the normal operation of the equipment.
[0014] Furthermore, rotating the bidirectional lead screw can drive the first and second closing plates to move towards or away from each other. When the two move towards each other and come into contact, the annular groove wraps around the female connector, further fixing it in place. The sealing gasket at the bottom of the first closing plate prevents water from entering from the connection point, providing excellent waterproofing. This makes it suitable for use in humid and other complex environments, extending the service life of the connector.
[0015] Furthermore, the sliding blocks installed on one side of the first and second closing plates serve as guides, ensuring the stability of the closing plate movement as the bidirectional screw drives the moving seat to move the closing plate, making the closing action smoother and more precise, avoiding jamming or misalignment during closing, and improving the convenience and effectiveness of operation.

[0023] 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.
[0024] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6The present invention provides the following technical solution: a waterproof plug with an anti-detachment structure, comprising a male plug 1 and a female plug 2, the female plug 2 being movably abutting against the interior of the male plug 1, a fixing plate 3 being installed on the side of the male plug 1 away from the female plug 2; a sliding rod 5 being slidably connected around the fixing plate 3, a limit block being provided at one end of the sliding rod 5, and a moving block 4 being fixedly connected to the other end of the sliding rod 5, a wire groove 6 being provided on one side of the moving block 4, the cable end of the female plug 2 being slidably connected inside the wire groove 6; an anti-detachment mechanism for preventing the female plug 2 from falling off is provided on the moving block 4; The anti-detachment mechanism includes a locking block 7, which is fixedly connected to both ends of the fixed plate 3 near the moving block 4. The locking block 7 is provided with a slot 15. A wedge block 8 is slidably connected inside the moving block 4. The contact surfaces of the locking block 7 and the wedge block 8 are complementary inclined surfaces. A moving plate 9 is installed on the side of the two wedge blocks 8 that are close to each other. The moving plate 9 is slidably connected inside the moving block 4. A spring 10 is installed on the side of the two moving plates 9 that are close to each other. The top of the spring 10 is installed inside the moving block 4. The wedge block 8 is movably locked inside the slot 15.
[0025] When male connector 1 and female connector 2 are not connected, the moving block 4 can slide freely on the sliding rods 5 around the fixed plate 3, such as Figure 1 and Figure 2 As shown, when it is necessary to insert the female plug 2 into the male plug 1, the cable end of the female plug 2 can be first inserted into the wire groove 6 from the side of the moving block 4, and then the female plug 2 and male plug 1 can be connected. After connection, as shown... Figure 3 and Figure 4 As shown, by moving the moving block 4, the moving block 4 drives the sliding rod 5 to slide on the fixed plate 3. As the moving block 4 moves, the engaging block 7 will gradually come into contact with the inclined surface on the wedge block 8, as shown. Figure 4 and Figure 6 As shown, as the wedge block 8 continues to move, the inclined surface of the wedge block 8 gradually presses against the locking block 7, causing the locking block 7 to move. Since the locking block 7 is fixed to the fixed plate 3, the wedge block 8, under the action of the inclined surface, will compress the elastic force of the two springs 10 and move them closer to each other, thereby causing the moving plate 9 to move synchronously. Figure 6 As shown, when the wedge block 8 moves to the point where it can no longer move, the slot 15 on the wedge block 8 will align with the position of the engaging block 7. The engaging block 7 will no longer be squeezed by the wedge block 8 and will reset under the action of the spring 10, thereby driving the moving plate 9 to move and reset synchronously, so that the engaging block 7 is engaged into the inside of the slot 15, thereby fixing the fixed plate 3 and the moving block 4, ensuring that the female plug 2 will not fall off unexpectedly after the female plug 2 and the male plug 1 are connected.
[0026] Example 2: Please refer to Figure 4 and Figure 5 Based on Embodiment 1, a fixing mechanism is also disclosed, the specific structure of which is as follows:
[0027] The fixing mechanism includes a first closing plate 11 and a second closing plate 16. Both the first closing plate 11 and the second closing plate 16 are slidably connected inside the moving block 4 and abut against each other. A sliding block 12 is installed on one side of both the first closing plate 11 and the second closing plate 16. A moving seat 13 is installed on the other side of both the first closing plate 11 and the second closing plate 16. A bidirectional lead screw 14 is rotatably connected to one side inside the moving block 4. The outer wall of the bidirectional lead screw 14 is threadedly connected to the moving seat 13. Annular grooves matching the female plug 2 are opened on the first closing plate 11 and the second closing plate 16, and a sealing gasket is installed at the bottom of the first closing plate 11.
[0028] When it is necessary to close the first closing plate 11 and the second closing plate 16, the bidirectional lead screw 14 on one side of the moving block 4 is rotated. Since the outer wall of the bidirectional lead screw 14 is threadedly connected to the moving seat 13 installed on the other side of the first closing plate 11 and the second closing plate 16, as shown... Figure 4 and Figure 5 As shown, and because the threads at both ends of the bidirectional lead screw 14 are in opposite directions, when the bidirectional lead screw 14 rotates, it will drive the two moving seats 13 to make linear movements in opposite directions. The movement of the moving seats 13 causes the first closing plate 11 and the second closing plate 16 to slide inside the moving block 4, as shown. Figure 4 and Figure 5 As shown, since the first closing plate 11 and the second closing plate 16 are provided with annular grooves that match the female plug 2, when the first closing plate 11 and the second closing plate 16 move towards each other and abut against each other, the annular grooves will wrap around the female plug 2, thereby further fixing the female plug 2. At the same time, the sealing gasket installed at the bottom of the first closing plate 11 can prevent water from entering from the connection part, thus playing a waterproof role. The sliding block 12 installed on one side of the first closing plate 11 and the second closing plate 16 plays a guiding role, ensuring the stability of the movement of the closing plate.
