One end of the metal ring is connected to an elastic band, and the other end is connected to the movable end of the elastic band with a mutually engaging and fastening connection component. This utility model has a simple and reasonable structure, is elastic, can connect tightly to pipe fittings, can adapt to pipe fittings of different sizes, and can prevent the clamping component from moving and the pipe fitting from loosening.

[0004] The inventors discovered in daily use that during the operation and use of pipe connection fasteners, the pipes would vibrate slightly during use, which was not conducive to the connection between the pipes and the fasteners, and caused the pipes and fasteners to easily fall off. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the existing technology, when operating pipe connection fasteners, the slight vibration of the pipe during use is not conducive to the connection between the pipe and the fastener, and the pipe and the fastener are prone to falling off.

[0006] To solve the above-mentioned technical problems, this utility model provides a hardware fastener for preventing loosening, including a fastener body and two pipes. The inner wall of the fastener body and the outer wall of the pipes are threaded together. The outer wall of the fastener body is provided with an anti-loosening device, which includes several fixing seats. The lower surface of the fixing seat is fixedly connected to the outer wall of the fastener body. A fixing rod is fixedly connected to one side of the fixing seat. A fixing ring is fixedly connected to one end of the fixing rod. Two screws are threaded through the outer wall of the fixing ring. A pressing plate is rotatably connected to the close ends of the two screws.

[0007] The aforementioned components achieve the following effect: they secure the pipes that are threadedly connected to the fastener body, preventing the pipes from loosening and falling off.

[0008] Preferably, the outer wall of the pipe is rotatably connected with a retaining ring, and one side of the extrusion plate is fixedly connected with a retaining plate, the retaining plate abutting against the retaining ring.

[0009] The effect achieved by the above components is to reinforce the fixation of the pipe by the extrusion plate.

[0010] Preferably, two guide plates are slidably provided on the outer wall of the fixing ring, and the ends of the two guide plates that are close to each other are fixedly connected to the extrusion plate.

[0011] The effect achieved by the above components is to guide the extrusion plate during movement and reduce the shaking of the extrusion plate during movement.

[0012] Preferably, a knob is fixedly connected to one end of the screw, and the knob has a number of anti-slip textures evenly distributed on its arc surface.

[0013] The effect achieved by the above-mentioned components is to facilitate the rotation of the screw.

[0014] Preferably, the fastener body is provided with an anti-backflow device, which includes a limiting ring. The arc surface of the limiting ring is fixedly connected to the interior of the fastener body. A sliding rod is slidably connected inside the limiting ring, and a baffle is fixedly connected to one end of the sliding rod.

[0015] The effect achieved by the above components is to restrict the unidirectional flow of water inside the fastener body, thereby reducing water pollution.

[0016] Preferably, a spring is fitted onto the arc surface of the slide rod, and the two ends of the spring are fixedly connected to one end of the slide rod and one side of the limiting ring, respectively.

[0017] The effect achieved by the above components is to make the baffle and the limiting ring fit tightly together using the spring.

[0018] Preferably, the baffle has an annular groove on the side near the limiting ring, and a sealing ring is fixedly connected inside the annular groove.

[0019] The effect achieved by the above components is to enhance the sealing between the baffle and the limiting ring.

[0020] Compared with related technologies, the anti-loosening hardware fastener provided by this utility model has the following beneficial effects:

[0021] By operating the anti-loosening device, the fastener body and the pipe are reinforced. First, the screw is rotated to push the extrusion plate to move, and the guide plate is used to prevent the extrusion plate from shaking. Then, the snap ring and the snap plate are tightly connected to fix the seat, fixing rod and fixing ring to prevent the pipe from loosening after it is connected with the fastener body.

[0022] By operating the anti-backflow device, the unidirectional flow of water through the fastener body is restricted. First, when the water flows normally, it pushes the slide bar and baffle to move to the other end so that the water flows through the fastener body. When the water flow weakens, the contracted spring rebounds and causes the baffle to fit against the limit ring to prevent the water from flowing back. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figures 1 to 6The present invention provides a hardware fastener for preventing loosening, comprising a fastener body 1 and two pipes 2, wherein the inner wall of the fastener body 1 and the outer wall of the pipes 2 are threadedly connected, the outer wall of the fastener body 1 is provided with an anti-loosening device 3, and the inside of the fastener body 1 is provided with an anti-backflow device 4.

[0033] In the embodiments of this utility model, please refer to Figure 3 and Figure 4 The anti-loosening device 3 includes several fixing seats 301. The lower surface of the fixing seat 301 is fixedly connected to the outer wall of the fastener body 1. A fixing rod 302 is fixedly connected to one side of the fixing seat 301. A fixing ring 303 is fixedly connected to one end of the fixing rod 302. Two screws 304 are threaded through the outer wall of the fixing ring 303. A pressing plate 305 is rotatably connected to the near end of the two screws 304. This achieves the effect of fixing the pipe 2 threadedly connected to the fastener body 1 and preventing the pipe 2 from loosening and falling off. A retaining ring 307 is rotatably connected to the outer wall of the pipe 2. A retaining plate 306 is fixedly connected to one side of the pressing plate 305. The retaining plate 306 abuts against the retaining ring 307. This achieves the effect of reinforcing the fixing of the pipe 2 by the pressing plate 305. Two guide plates 308 are slidably passed through the outer wall of the fixing ring 303. The near end of the two guide plates 308 is fixedly connected to the pressing plate 305. This design effectively guides the moving extrusion plate 305, reducing its wobbling during movement. A knob 309 is fixedly connected to one end of the screw 304. The knob 309 has several evenly spaced anti-slip grooves 310 on its arc-shaped surface, facilitating the rotation of the screw 304.

[0034] In the embodiments of this utility model, please refer to Figure 5 and Figure 6 The anti-backflow device 4 includes a limiting ring 41, the arc surface of which is fixedly connected to the interior of the fastener body 1. A sliding rod 45 is slidably connected inside the limiting ring 41, and a baffle 42 is fixedly connected to one end of the sliding rod 45. This restricts the unidirectional flow of water inside the fastener body 1, reducing water pollution. A spring 46 is fitted onto the arc surface of the sliding rod 45, and both ends of the spring 46 are fixedly connected to one end of the sliding rod 45 and one side of the limiting ring 41, respectively. This allows the spring 46 to tightly fit the baffle 42 against the limiting ring 41. An annular groove 43 is formed on the side of the baffle 42 near the limiting ring 41, and a sealing ring 44 is fixedly connected inside the annular groove 43. This enhances the sealing effect between the baffle 42 and the limiting ring 41.

[0035] The working principle of the anti-loosening hardware fastener provided by this utility model is as follows: When the anti-loosening device 3 is required to prevent the fastener body 1 from loosening from the pipe 2, first turn the knob 309 to drive the screw 304 to move the pressing plate 305 to both sides, and then thread the outer wall of the pipe 2 to the inner wall of the fastener body 1. After the pipe 2 is connected to the fastener body 1, turn the screw 304 to make the clamping plate 306 and the clamping ring 307 tightly abut against each other. At this time, the guide plate 308 will have a fixed guiding effect on the pressing plate 305, preventing the pressing plate 305 from shaking and facilitating the abutment of the clamping plate 306 and the clamping ring 307. When the pipe 2 rotates, due to the abutment of the clamping plate 306 and the clamping ring 307, the fixing ring 303 restricts the movement of the pressing plate 305 and the clamping plate 306, and the fixing rod 302 fixes the fixing ring 303 so that the pipe 2 cannot move, thereby preventing the pipe 2 from loosening.

[0036] When the water in pipe 2 needs to flow in one direction and the anti-backflow device 4 is used, the water in pipe 2 flows in from the end of the fastener body 1 away from the baffle 42, pushing the slide rod 45 to move along the inside of the limiting ring 41 to the other end. The movement of the slide rod 45 pushes the baffle 42 connected to the pipe 2 to move, causing the baffle 42 to separate from the limiting ring 41. After the baffle 42 separates from the limiting ring 41, the water will flow out through the gap between the baffle 42 and the fastener body 1. When the water flow at the inlet of the fastener body 1 is small, the spring 46 of the slide rod 45's arc surface contracts and drives the baffle 42 to move, so that the baffle 42 sticks to the limiting ring 41. The sealing ring 44 inside the annular groove 43 of the baffle 42 will strengthen the sealing effect between the baffle 42 and the limiting ring 41 to prevent water backflow.

[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
