[0034] 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.
[0035] In one embodiment, such as Figures 1-4 As shown, a free-rotating quick fastener includes a fastener body 1. The upper and lower ends of the fastener body 1 are symmetrically formed with two arc-shaped outer walls. A slide rail 4 is provided on the outer side of the fastener body 1. The vertical cross-section of the slide rail 4 is C-shaped. The slide rail 4 is sleeved on the outer wall of the fastener body 1. The fastener body 1 is in contact with the inner wall of one end of the slide rail 4. A component mounting plate 3 is provided at one end of the slide rail 4. The component mounting plate 3 is tightly fitted with the outer wall of the slide rail 4. A fastening mechanism is provided on the fastener body 1 for fastening the component mounting plate 3 and the slide rail 4.
[0036] The fastening mechanism includes a rotating assembly mounted on the component mounting plate 3;
[0037] The rotating component is a fastening bolt 205 located at the end of the component mounting plate 3 away from the slide rail 4. The fastening bolt 205 penetrates the component mounting plate 3 to the interior of the slide rail 4. The fastener body 1 is sleeved on the outer wall of the fastening bolt 205 and is threadedly connected to the fastening bolt 205.
[0038] A protective component is provided on the fastening bolt 205;
[0039] In this embodiment, during use, the fastening bolt 205 is passed through the slot on the component mounting plate 3 from one end of the component mounting plate 3 to the outside of the other end. Then, the fastener body 1 is rotated to fit the outer wall of the fastening bolt 205, so that the fastener body 1 and the fastening bolt 205 are threadedly connected. During this process, the fastening mechanism can ensure that the fastener body 1 is in a horizontal state, thereby effectively preventing the fastener body 1 from being misaligned with the opening of the slide rail 4 due to its rotation during the contact between the component mounting plate 3 and the slide rail 4.
[0040] Then, push the component mounting plate 3 to insert the fastener body 1 into the inner cavity of the slide rail 4. Then, use a tool to drive the fastening bolt 205 to rotate. At this time, the fastener body 1 rotates in the inner cavity of the slide rail 4 through the thread driven by the fastening bolt 205. When the fastener body 1 is in a vertical state after rotating, the outer walls of the upper and lower ends of the fastener body 1 are in contact with the inner wall of the slide rail 4. During this process, the fastener body 1 slides with the inner wall of the slide rail 4 through the arc surface. In this way, the slide rail 4 can limit the rotation of the fastener body 1. Then continue to rotate the fastening bolt 205. At this time, the fastener body 1 slides along the inner wall of the slide rail 4 through the thread driven by the fastening bolt 205 until the fastener body 1 contacts the inner wall of one end of the slide rail 4. In this way, the component mounting plate 3 and the slide rail 4 can be quickly fastened through the fastener body 1.
[0041] When it is necessary to adjust the position of the component mounting plate 3, the above operation is reversed. This allows the fastener body 1 to separate from the inner wall of one end of the slide rail 4, thereby releasing the fastening connection between the component mounting plate 3 and the slide rail 4. Then, the component mounting plate 3 is pulled to move on the outside of the slide rail 4. This allows for convenient adjustment of the position of the component mounting plate 3 according to the actual situation during component installation, thereby further improving the efficiency of component installation.
[0042] In one embodiment, such as Figures 1-3As shown, the protective component includes: a flat washer 206 fitted onto the outer wall of the fastening bolt 205, the flat washer 206 being located at the end of the component mounting plate 3 away from the slide rail 4, and a spring washer 207 being provided at one end of the flat washer 206, the spring washer 207 being fitted onto the outer wall of the fastening bolt 205, the spring washer 207 being located between the flat washer 206 and the component mounting plate 3, and the spring washer 207 being in close contact with the outer wall of the component mounting plate 3. The flat washer 206 and the spring washer 207 are used to protect the surface of the component mounting plate 3 and can also effectively prevent the fastening bolt 205 from loosening during use.
[0043] The fastener body 1 is provided with a first anti-slip component;
[0044] In one embodiment, such as Figures 2-4 As shown, the first anti-slip component includes two sets of reinforcing embossing 204 symmetrically opened on the outer wall of one end of the fastener body 1. The two sets of reinforcing embossing 204 are respectively located at the upper and lower ends of one end of the fastener body 1. The two sets of reinforcing embossing 204 are symmetrically arranged on the outside of the fastening bolt 205. The outer wall of the fastener body 1 at the position of the two sets of reinforcing embossing 204 is in contact with the inner wall of the slide rail 4. The two sets of reinforcing embossing 204 formed by cold extrusion can strengthen the metal in the area around the reinforcing embossing 204 of the fastener body 1, which can effectively increase the friction between the fastener body 1 and the inner wall of the slide rail 4. Moreover, the inner wall of the reinforcing embossing 204 can be modified into a pentagon or other shapes according to production needs. At the same time, the fastener body 1 has an indentation with a depth of 0.2 mm and a width of 1 mm at the opening position of the reinforcing embossing 204, which can further improve the aesthetics of the fastener body 1.
[0045] A second anti-slip component is provided on the fastener body 1;
[0046] The second anti-slip component includes: a connecting push ring 209 disposed at one end of the fastener body 1, the connecting push ring 209 being located outside the fastening bolt 205, the connecting push ring 209 being in contact with the outer wall of the fastener body 1, and an annular rubber pad 208 being fixedly connected to the end of the connecting push ring 209 away from the fastener body 1, the annular rubber pad 208 being in contact with the outer wall of the component mounting plate 3. Through the cooperation of the first anti-slip component and the second anti-slip component, the friction between the fastener body 1 and the inner wall of the slide rail 4 can be increased, and the fastener body 1 can be prevented from rotating during the process of entering the inner cavity of the slide rail 4.
[0047] A sliding component is provided on the connecting push ring 209;
[0048] In one embodiment, such as Figures 2-3As shown, the sliding assembly includes two limiting slide rods 202 that are symmetrically fixedly connected to the end of the connecting push ring 209 away from the annular rubber pad 208. Both limiting slide rods 202 extend through to the outside of the end of the fastener body 1 away from the connecting push ring 209, and both limiting slide rods 202 are slidably connected to the fastener body 1.
[0049] A limit component is provided on the limit slide bar 202;
[0050] The limiting component is a limiting baffle 201 fixedly connected to the end of the limiting slide bar 202 away from the connecting push ring 209. The limiting baffle 201 is located at the end of the fastener body 1 away from the connecting push ring 209.
[0051] A reset component is provided on the limit slide bar 202;
[0052] The reset component is a spring 203 sleeved on the outer wall of the limiting slide bar 202. One end of the spring 203 is in contact with the outer wall of the connecting push ring 209, and the other end of the spring 203 is in contact with the inner wall of the fastener body 1. Through the cooperation of the sliding component, the limiting component and the reset component, the annular rubber pad 208 can always be in contact with the outer wall of the component mounting plate 3.
[0053] The above embodiment discloses a free-rotating quick fastener, wherein, in use, the fastening bolt 205 is passed through the hole slot on the component mounting plate 3 from one end of the component mounting plate 3 to the outside of the other end, and then the fastener body 1 is rotated to fit the outer wall of the fastening bolt 205, thereby enabling the fastener body 1 and the fastening bolt 205 to be threadedly connected.
[0054] During this process, the fastener body 1 pushes the connecting push ring 209 through the limiting slide rod 202 so that the annular rubber pad 208 contacts the outer wall of the component mounting plate 3. At this time, it is ensured that the fastener body 1 is in a horizontal state, thereby effectively preventing the fastener body 1 and the fastening bolt 205 from being misaligned due to rotation during the contact between the component mounting plate 3 and the slide rail 4.
[0055] Then, push the component mounting plate 3 to insert the fastener body 1 into the inner cavity of the slide rail 4. Then, use a tool to drive the fastening bolt 205 to rotate. At this time, the fastener body 1 rotates in the inner cavity of the slide rail 4 through the thread driven by the fastening bolt 205. When the fastener body 1 is in a vertical state after rotating, the outer walls of the upper and lower ends of the fastener body 1 are in contact with the inner wall of the slide rail 4. During this process, the fastener body 1 slides with the inner wall of the slide rail 4 through the arc surface. At the same time, the connecting push ring 209 drives the annular rubber pad 208 to rotate along the outer wall of the component mounting plate 3 through the limiting slide rod 202 driven by the fastener body 1. In this way, the fastener body 1 can be rotated and limited by the slide rail 4.
[0056] Then continue to rotate the fastening bolt 205. At this time, the fastener body 1 slides along the inner wall of the slide rail 4 and the outer wall of the limiting slide rod 202 through the thread driven by the fastening bolt 205, until the fastener body 1 drives the two sets of reinforcing embossing 204 to contact the inner wall of one end of the slide rail 4. At this time, the two sets of reinforcing embossing 204 effectively increase the friction between the fastener body 1 and the inner wall of the slide rail 4. During this process, the fastener body 1 separates from the limiting baffle 201 by moving and compresses the spring 203 to retract. In this way, the component mounting plate 3 and the slide rail 4 can be quickly fastened through the fastener body 1.
[0057] When the position of the component mounting plate 3 needs to be adjusted, the above operation is reversed. This separates the fastener body 1 from the inner wall of one end of the slide rail 4, thereby releasing the fastening connection between the component mounting plate 3 and the slide rail 4. Then, the component mounting plate 3 is pulled to move on the outside of the slide rail 4. This allows for convenient adjustment of the position of the component mounting plate 3 according to the actual situation during component installation, thereby further improving the efficiency of component installation.
[0058] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
