Description

Technical Field

[0001] This utility model relates to the field of pipeline sealing technology, and in particular to a plastic plug with an anti-detachment buckle. Background Technology

[0002] In modern industrial production, plastic plugs are plastic products used to seal the ports of pipes, fittings, or equipment, serving to seal, prevent dust, prevent leakage, or protect the internal structure. Plastic plugs are widely used for the sealing and protection of pipes, containers, equipment, etc. With their unique characteristics and wide range of applications, plastic plugs play an important role in many industries.

[0003] Existing traditional plastic plugs often face the problem of being prone to falling off or loosening during use. Especially under conditions such as vibration, pressure fluctuations, or temperature changes, the stability and reliability of the plugs are greatly challenged, leading to sealing failure and leakage. In addition, the installation and removal of some plugs are quite troublesome, requiring the use of tools or the application of considerable force, which causes inconvenience to users. Therefore, we propose a plastic plug with an anti-loosening buckle to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a plastic plug with an anti-detachment buckle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A plastic plug with an anti-detachment buckle includes a plug body. Rotating rods are rotatably connected to the front and rear sides of the plug body's inner cavity. A worm gear is fixedly sleeved on the rear side of the outer side of the rotating rod. A worm adapted to the worm gear is rotatably connected to the bottom of the plug body's inner cavity. A rotating seat is fixedly sleeved on the front side of the outer side of the rotating rod. Support rods are fixedly installed at the top and bottom of the front side of the rotating seat. Connecting rods are movably sleeved on the outer side of each support rod. Connecting seats are rotatably connected to the left side of the top connecting rod and the right side of the bottom connecting rod. Positioning blocks are fixedly installed on the left side of the left connecting seat and the right side of the right connecting seat. A protective cover is rotatably connected to the top left side of the plug body via a hinge. A rectangular locking block is fixedly installed on the right side of the bottom of the protective cover.

[0007] Preferably, the left side of the positioning block on the left and the right side of the positioning block on the right both movably penetrate the plug body, and a support block is movably sleeved on the outer side of the positioning blocks on both the left and right sides, with the bottom of the support block fixedly connected to the bottom of the inner cavity of the plug body.

[0008] Preferably, a first magnet is fixedly installed on the left side of the rectangular card block, and a second magnet adapted to the first magnet is fixedly installed on the right side of the plug body.

[0009] Preferably, the top of the worm gear moves through the plug body and is fixedly connected to a knob, and an anti-slip pad is fixedly embedded on the outside of the knob.

[0010] Preferably, an annular sealing gasket is fixedly installed at the bottom of the plug body.

[0011] Preferably, the outer side of the positioning block is in sliding contact with the inner side of the support block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, rotating the knob in the forward direction drives the worm gear to rotate, which in turn drives the matching worm wheel to rotate. The worm wheel drives the rotating rod to rotate, which in turn drives the rotating seat to rotate. The rotating seat, through the support rod, drives the top and bottom connecting rods to move to the left and right respectively. The connecting rod, through the connecting seat, drives the positioning blocks on the left and right sides to move away from each other, so that the positioning blocks extend out of the plug body and abut against the sealing object. The worm gear has the advantage of self-locking, which avoids the problem of easy detachment or loosening during use, and facilitates quick installation and use by the user, ensuring the sealing effect.

[0014] 2. In this utility model, the rectangular block is moved upward by the cooperation of the protective cover, the rectangular block, the first magnet and the second magnet. The rectangular block moves the first magnet away from the second magnet and opens the protective cover at the same time, which can protect the knob and prevent the knob from being accidentally touched, thus improving the practicality of the device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A plastic plug with anti-detachment buckle includes a plug body 1. Rotating rods 6 are rotatably connected to the front and rear sides of the inner cavity of the plug body 1. A worm gear 7 is fixedly sleeved on the rear side of the outer side of the rotating rod 6. A worm 8 adapted to the worm gear 7 is rotatably connected to the bottom of the inner cavity of the plug body 1. A rotating seat 9 is fixedly sleeved on the front side of the outer side of the rotating rod 6. Support rods 10 are fixedly installed on the top and bottom of the front side of the rotating seat 9. Connecting rods 11 are movably sleeved on the outer side of the support rods 10. Connecting seats 12 are rotatably connected to the left side of the top connecting rod 11 and the right side of the bottom connecting rod 11. Positioning blocks 13 are fixedly installed on the left side of the left connecting seat 12 and the right side of the right connecting seat 12. A protective cover 2 is rotatably connected to the top left side of the plug body 1 via a hinge. A rectangular locking block 3 is fixedly installed on the bottom right side of the protective cover 2.

[0022] In this embodiment, the left side of the left positioning block 13 and the right side of the right positioning block 13 both movably penetrate the plug body 1. Support blocks 14 are movably sleeved on the outer sides of the positioning blocks 13 on both the left and right sides. The bottom of the support blocks 14 is fixedly connected to the bottom of the inner cavity of the plug body 1. The support blocks 14 on the left and right sides can limit the positioning blocks 13, improving the stability of the left and right movement of the positioning blocks 13. A first magnet 4 is fixedly installed on the left side of the rectangular locking block 3, and a second magnet 5 that matches the first magnet 4 is fixedly installed on the right side of the plug body 1. Through the cooperation of the first magnet 4 and the second magnet 5, the protective cover 2 can be fixed, preventing the protective cover 2 from loosening.

[0023] In this embodiment, the top of the worm gear 8 moves through the plug body 1 and is fixedly connected to a knob 16. An anti-slip pad 17 is fixedly embedded on the outside of the knob 16. The anti-slip pad 17 can increase the friction between the user's hand and the knob 16, making it easier to rotate the knob 16. An annular sealing pad 15 is fixedly installed at the bottom of the plug body 1. The annular sealing pad 15 improves the sealing between the plug body 1 and the sealing object. The outside of the positioning block 13 slides in contact with the inside of the support block 14.

[0024] In this embodiment, during use, by moving the rectangular block 3 upward, the rectangular block 3 causes the first magnet 4 to move away from the second magnet 5, and at the same time, the protective cover 2 is opened. Then, the knob 16 is turned clockwise, and the knob 16 causes the worm gear 8 to rotate. The worm gear 8 causes the matching worm wheel 7 to rotate. The worm wheel 7 causes the rotating rod 6 to rotate. The rotating rod 6 causes the rotating seat 9 to rotate. The rotating seat 9 causes the top and bottom connecting rods 11 to move to the left and right respectively through the support rod 10. The connecting rod 11 causes the positioning blocks 13 on the left and right sides to move away from each other through the connecting seat 12, so that the positioning blocks 13 extend out of the plug body 1 and abut against the sealing object.

[0025] The above provides a detailed description of a plastic plug with an anti-detachment buckle provided by this utility model.
