[0003] Traditionally, when connecting and fixing two pipe fittings, the two fittings are first inserted to align the screw holes on them. Then, the screw is inserted into the screw hole and passed through. Finally, the washer and nut are installed on the screw to fix the two pipe fittings. However, in actual use, it has been found that during long-term use after installation, some vibrations and bumps may occur, causing the screw connection to loosen, thus affecting the stability of the pipe fittings. Utility Model Content

[0004] The technical problem this utility model aims to solve is that during long-term use after installation, some vibrations and bumps may occur, causing the screw connection to loosen, thereby affecting the stability of the pipe fitting.

[0006] The effect achieved by the above components is as follows: when the fasteners are used to connect and fix the two pipe fittings, the two pipe fittings are first inserted to align the screw holes on the two pipe fittings, then the screw is inserted into the screw hole and passes through, then the reinforcement device is installed and fixed at the position of the nut and the screw, and then the washer and nut are installed on the screw in sequence, thereby realizing the connection and fixation of the two pipe fittings.

[0007] Preferably, the reinforcement device includes a mounting frame, wherein the mounting frame is snapped onto the surface of the nut, and mounting shafts are fixedly connected to both sides of the surface of the mounting frame, wherein a connecting plate is rotatably disposed on the arc surface of the mounting shaft, an arc plate is fixedly connected to the surface of the connecting plate, a reinforcement pad is fixedly connected to the inner wall of the arc plate, and a mounting groove is formed on the arc surface of the arc plate, and a retaining plate is sleeved on the arc surface of the screw, wherein the two ends of the retaining plate are respectively inserted into the mounting grooves on the two arc plates.

[0008] The effect achieved by the above components is that when the fasteners are used to connect and fix two pipe fittings, they can better maintain the stability of the pipe fittings and prevent the screw from turning loose, thus ensuring the effectiveness of the fasteners and improving the practicality of the fasteners in reinforcing the components.

[0009] Preferably, a reinforcing ring is installed on the inner wall of the mounting frame, wherein the reinforcing ring improves the connection stability between the mounting frame and the nut.

[0010] The effect achieved by the above components is that the rubber reinforcing ring further increases the friction between the mounting frame and the nut when they are snapped together, resulting in a more stable assembly and improved effectiveness of the reinforcement device.

[0011] Preferably, the inner walls on both sides of the mounting frame are slidably provided with a retaining plate, wherein a spring is installed on one side of the retaining plate, and the other end of the spring is connected and fixed to the inner wall of the side of the mounting frame.

[0013] Preferably, the inner wall of the positioning plate is fixedly connected to two positioning blocks, wherein the positioning blocks are slidably configured with a groove opened on the arc surface of the screw.

[0014] The effect achieved by the above components is that, by setting the positioning block, when the positioning plate is slidably sleeved on the screw, the two sides of the positioning plate can be inserted into the mounting groove on the surface of the arc plate more quickly and accurately.

[0015] Preferably, the surface of the nut is provided with a reinforcing component, wherein the reinforcing component improves the stability of the nut assembly.

[0016] The effect achieved by the above components is that by strengthening the components, the effectiveness of the reinforcement device is further improved, thereby further improving the assembly effect of the fasteners.

[0019] Preferably, the reinforcing component further includes an anti-slip sleeve installed and fixed on the arc surface of the mounting tube, wherein the anti-slip sleeve improves the ease of use of the mounting tube.

[0020] The effect achieved by the above components is that the rubber anti-slip sleeve makes the installation tube more convenient and quick to rotate, thereby better installing and fixing the nuts of adjacent fasteners.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Example 1, Figure 1 and Figure 2 The illustrated combination fastener includes a nut 1, a screw 2 fixedly connected to the surface of the nut 1, a washer 4 sleeved on the arc surface of the screw 2, a nut 3 threadedly connected to the arc surface of the screw 2, a reinforcing device 5 provided on the surface of the nut 1, wherein the reinforcing device 5 further reinforces the pipe fitting installed by means of an arc plate 54, and a reinforcing component 6 provided on the surface of the nut 3.

[0032] Figure 1 , Figure 2 and Figure 3 The reinforcement device 5 shown includes a mounting frame 51, which is snapped onto the surface of the nut 1. Mounting shafts 52 are fixedly connected to both sides of the mounting frame 51. A connecting plate 53 is rotatably mounted on the arc surface of the mounting shaft 52. An arc-shaped plate 54 is fixedly connected to the surface of the connecting plate 53. A reinforcing pad 57 is fixedly connected to the inner wall of the arc-shaped plate 54, and a mounting groove 56 is formed on the arc surface of the arc-shaped plate 54. A retaining plate 59 is fitted onto the arc surface of the screw 2, with both ends of the retaining plate 59 interlocking with the mounting grooves 56 on the two arc-shaped plates 54. When using the fastener to connect and fix the two pipe fittings, first, the two pipe fittings are inserted to align the screw holes on the two pipe fittings. Then, the screw 2 is inserted into the screw hole and passes through. Finally, the mounting frame 51 is snapped onto the screw. On the surface of cap 1, rotate the arc plates 54 on both sides, so that the connecting plate 53 fixedly connected to the surface of the arc plate 54 rotates on the arc surface of the mounting shaft 52 fixedly connected to the surface of the mounting frame 51, so that the arc plate 54 fits against the arc surface of the pipe fitting. Then, put the positioning plate 55 on the arc surface of the screw 2, so that the two ends of the positioning plate 55 are respectively inserted into the mounting grooves 56 on the surface of the arc plates 54 on both sides. Then, put the washer 4 on the screw 2. Finally, thread the nut 3 onto the screw 2 until the nut 3 and the auxiliary washer 4 contact and press against the surface of the positioning plate 55. At this time, when the fastener connects and fixes the two pipe fittings, it can better maintain the stability of the pipe fittings and is not easy to cause the screw 2 to rotate and loosen, ensuring the use effect of the fastener and improving the practicality of the fastener for strengthening the component.

[0033] Figure 1 , Figure 2 and Figure 3The inner wall of the mounting frame 51 shown is equipped with a reinforcing ring 58, which improves the connection stability between the mounting frame 51 and the nut 1. The rubber reinforcing ring 58 further increases the friction between the mounting frame 51 and the nut 1 during engagement, resulting in a more stable assembly and improving the effectiveness of the reinforcement device 5. Two retaining plates 59 are slidably mounted on the inner walls of both sides of the mounting frame 51. A spring 510 is mounted on one side of each retaining plate 59, and the other end of the spring 510 is connected and fixed to the inner wall of the side of the mounting frame 51. The retaining plates 59 secure the arc-shaped plate 54 to the pipe. After the curved surface of the component is closed, the clamping plate 59 is released, so that the clamping plate 59 is clamped on one end surface of the connecting plate 53 under the elastic force of the spring 510. At this time, the clamping plate 59 is limited and does not easily rotate, thus making it more convenient to use and fix the curved plate 54. Two positioning blocks 511 are fixedly connected to the inner wall of the positioning plate 55. The positioning blocks 511 are slidably set with the sliding groove opened on the curved surface of the screw 2. Through the setting of the positioning blocks 511, when the positioning plate 55 is slidably sleeved on the screw 2, the two sides of the positioning plate 55 can be inserted into the mounting groove 56 on the surface of the curved plate 54 more quickly and accurately.

[0034] Figure 1 and Figure 4 The reinforcing component 6 shown includes a stabilizing ring 61, which is fitted onto the surface of the nut 3. Threaded posts 62 are fixedly connected to the four sides of the stabilizing ring 61, and an installation tube 63 is threaded onto the arc surface of the threaded posts 62. A steel wire rope 64 is installed at one end of the installation tube 63. When fasteners are used to connect the pipe fittings, and the nut 3 is installed, the stabilizing ring 61 is fitted onto the surface of the nut 3. Then, the installation tube 63 is threaded onto the threaded posts 62 fixedly connected to the surface of the stabilizing ring 61 at a position opposite to the adjacent fastener. Similarly, the other end of the installation tube 63 of the steel wire rope 64 is fitted onto the surface of the nut 3 on the adjacent pipe fitting. Because the steel wire rope 64 is installed on the installation tube 63 in a knot-like manner, it is less prone to twisting and maintains a stable taut state. Therefore, when the adjacent fasteners are in use, the nut 3 is less likely to loosen or rotate, thus better ensuring the installation and fixation of the pipe fittings by the reinforcement device 5 assisting the fasteners.

[0035] Figure 1 and Figure 4 The reinforcing component 6 shown also includes an anti-slip sleeve 65 installed and fixed on the arc surface of the mounting tube 63. The anti-slip sleeve 65 improves the ease of use of the mounting tube 63. The rubber anti-slip sleeve 65 makes it easier and faster to rotate the mounting tube 63, thereby better installing and fixing the nuts 3 of the adjacent fasteners.

[0036] Working principle: When fasteners are used to connect and fix two pipe fittings, first insert the two pipe fittings to align the screw holes on the two pipe fittings, then insert the screw 2 into the screw hole and pass through it. Then, the mounting frame 51 is snapped onto the surface of the nut 1. Next, rotate the arc-shaped plates 54 on both sides so that the connecting plate 53 fixedly connected to the surface of the arc-shaped plate 54 rotates on the arc surface of the mounting shaft 52 fixedly connected to the surface of the mounting frame 51, so that the arc-shaped plate 54 fits against the arc surface of the pipe fitting. Finally, the positioning plate 55 is fitted onto the pipe fitting. On the arc surface of the screw 2, the two ends of the positioning plate 55 are inserted into the mounting grooves 56 on the surface of the arc plate 54 on both sides. Then, the washer 4 is put on the screw 2, and finally the nut 3 is threaded onto the screw 2 until the nut 3 and the washer 4 contact and press against the surface of the positioning plate 55. At this time, when the fastener connects and fixes the two pipes, it can better maintain the stability of the pipes and is not easy for the screw 2 to rotate and loosen, thus ensuring the use effect of the fastener and improving the practicality of the fastener in strengthening the components.

[0037] When using fasteners to connect pipe fittings, and after the nut 3 is installed, the stabilizing ring 61 is fitted onto the surface of the nut 3. Then, the mounting tube 63 is threaded onto the threaded post 62 fixedly connected to the surface of the stabilizing ring 61 at the position opposite to the adjacent fastener. Similarly, the mounting tube 63 at the other end of the wire rope 64 is fitted onto the surface of the nut 3 on the adjacent pipe fitting. Because the wire rope 64 is installed on the mounting tube 63 in a knot-like manner, the wire rope 64 is not easy to twist and is kept in a stable and taut state. At this time, when the adjacent fasteners are in use, the nut 3 is less likely to loosen and rotate, thus better ensuring the installation and fixation of the pipe fitting by the fasteners assisted by the reinforcement device 5.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
