Description

Technical Field

[0001] This utility model relates to the field of tube buckle technology, specifically a novel tube buckle. Background Technology

[0002] As is well known, the installation of air conditioning ducts usually requires positioning the ducts, which is done using duct connectors for positioning and fixing.

[0003] For example, the utility model patent with application publication number CN218430779U, application publication date February 3, 2023, and titled "A Connecting Buckle for Air Conditioner Connecting Pipes," describes the specific structure of a connecting buckle for air conditioner connecting pipes. It includes a buckle ring, with an end plate and a protruding plate fixedly connected to both ends of the buckle ring. A protective structure is provided on the inner outer surface of the buckle ring, and an adhesive component is fixedly connected to the outer surface of the buckle ring. The protective structure includes a protective layer connected to the inner outer surface of the buckle ring, a spring connecting the inner wall of the protective layer to the buckle ring, a hollow column fixedly connected to the outer surface of the inner wall of the protective layer, a connecting column fixedly connected to the outer surface of the buckle ring corresponding to the hollow column, a protruding strip fixedly connected to one end of the outer surface of the buckle ring, a locking strip fixedly connected to the outer surface of the end plate, and a locking hole formed on the outer surface of the end plate.

[0004] The shortcomings of the existing technology are that the protruding strips and locking strips of the buckle are used to abut and limit the locking of the end plates and protruding plates at both ends of the buckle. At this time, the two ends of the buckle are interlocked to form a ring to fix the pipe. However, the two sides of the end plates and protruding plates are directly exposed, and the end plates and protruding plates are often made of metal. Therefore, the protruding strips and locking strips are easily wetted by external moisture or liquids leaking from the outside of the pipe, which will cause corrosion and damage. This makes the buckle joint brittle due to corrosion and prone to breakage. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of pipe clamp to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel pipe buckle, comprising a buckle ring with a mating end and an insertion end at its two ends. The mating end is provided with an insertion groove and an insertion groove. An anti-reverse tooth is fixedly provided in the insertion groove. A limiting tooth and a shielding strip are fixedly provided on the insertion end. The insertion end is inserted into the mating end by means of the limiting tooth and the anti-reverse tooth. After the shielding strip deforms past the top of the mating end, it passes through the insertion groove and is then attached to the top of the mating end again.

[0007] As a further description of the above technical solution: a first Velcro fastener is fixedly provided on the first side of the masking strip, and a second Velcro fastener is fixedly provided on the second side of the masking strip.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] Example 1

[0027] Combination Figure 1 and Figure 2 As shown, this example adds a waterproof structure to the pipe coupling connection on the basis of the original pipe coupling, namely, a shielding strip 2 fixedly installed on the insertion end 12. First, the insertion end 12 is inserted into the insertion groove 111 of the mating end 11. At this time, several limiting teeth 121 move to the space between the anti-retraction teeth 112, and then the limiting teeth 121 and anti-retraction teeth 112 complete the fixation of the buckle 1. The buckle 1 is then fitted and fixed to the outside of the pipe. Then, the shielding strip 2 is bent and deformed to shield the outer top surface of the mating end 11. The shielding strip 2 is bent again, and the end of the shielding strip 2 is passed through the insertion groove 113 and deformed again to cover the outer top surface of the mating end 11. At this time, the shielding strip 2 completes the axial side protection of the mating end 11 and the insertion end 12, thereby alleviating the situation where external water vapor or liquid leakage from the outside of the pipe wets the insertion end 12 and the mating end 11, improving the protection of the anti-reverse tooth 112 and the limiting tooth 121, reducing the corrosion rate of the connection of the fastener 1, and improving the fixed installation stability of the fastener 1.

[0028] Specifically, the end of the masking strip 2 is glued to the insertion end 12 of the buckle 1, and the masking strip 2 is a flexible strip to facilitate the deformation and bending of the masking strip 2. The insertion groove 113 is a through groove to facilitate the masking strip 2 to pass through the mating end 11.

[0029] In the above technical solution, the shielding strip 2 is used to shield and protect the axial sides of the mating end 11 and the plug end 12, thereby alleviating the situation where external water vapor or liquid leakage from the outside of the pipeline wets the plug end 12 and the mating end 11, improving the protection of the anti-reverse tooth 112 and the limiting tooth 121, reducing the corrosion rate of the connection of the fastener 1, and improving the fixed installation stability of the fastener 1.

[0030] Example 2

[0031] Combination Figure 1 and Figure 2 As shown, this embodiment further improves upon Embodiment 1 by fixing a first Velcro 3 and a second Velcro 4 to both sides of the masking tape 2. When the masking tape 2 bends and deforms to cover the outer top surface of the mating end 11, the second Velcro 4 is located on the outer top surface of the mating end 11. Then, the masking tape 2 is bent again, and its end passes through the insertion groove 113 and deforms again to cover the outer top surface of the mating end 11. At this time, the first Velcro 3 on the masking tape 2 can deform to fit onto the second Velcro 4, thus completing the fixation of the masking tape 2 and improving the protective effect of the masking tape 2 on the fastener 1. Furthermore, the first Velcro 3 and the second Velcro 4 are used to further fix the masking tape 2 to the mating end 11, thereby further improving the fixation stability of the fastener 1 connection.

[0032] Specifically, such as Figure 1 As shown, the side of the shielding strip 2 near the top outer surface of the plug-in end 12 is the first side surface, as shown below. Figure 2 As shown, the side of the shielding strip 2 near the inner limiting tooth 121 of the plug end 12 is the second side.

[0033] Example 3

[0034] Combination Figure 3 As shown, this embodiment further improves the masking strip 2 based on embodiment one. Specifically, several core pins 6 are pre-embedded in the masking strip 2. The core pins 6 pre-embedded in the masking strip 2 are used to improve the compressive strength of the masking strip 2 in the short side direction, thereby avoiding the problem of the masking strip 2 becoming wrinkled and deformed in the short side direction, which would reduce the masking effect of the masking strip 2, and further improving the protection of the connection of the fastener 1 by the masking strip 2.

[0035] Specifically, the core needle 6 is a rigid component and is arranged in an array along the long side of the masking strip 2, thereby enabling the masking strip 2 to still bend and deform along the long side.

[0036] Example 4

[0037] Combination Figure 2As shown, this embodiment provides an additional structure for further sealing and waterproofing the periphery of the plug-in end 12 based on embodiment two. One end of the flip-over band 5 is fixedly set on the shielding band 2. When the shielding band 2 has deformed and shielded the outside of the mating end 11, the second side of the flip-over band 5 is located on the outer ring side of the buckle 1, so that the flip-over band 5 is also located on the outer ring side of the buckle 1. The flip-over band 5 can be flipped to fit the outer ring surface of the plug-in end 12. Then, the extension 51 of the flip-over band 5 passes over the axial side of the plug-in end 12 and extends into the inner ring side of the plug-in end 12. The flip-over band 5 and the extension 51 are used to further complete the shielding protection of the periphery of the plug-in end 12, and further improve the protection of the connection of the buckle 1.

[0038] Specifically, the extension 51 is integrally formed with the flipping belt 5, and the end of the flipping belt 5 is glued to the cover belt 2. Alternatively, adhesive strips that can be glued to each other can be provided on the extension 51, so that the extension 51 can be stably attached to the inner side of the buckle 1.

[0039] Example 5

[0040] Combination Figure 2 and Figure 4 As shown, this embodiment further improves the buckle 1 based on embodiment 3. Specifically, a mating hole 114 is opened in the insertion groove 113. When the shielding strip 2 passes through the insertion groove 113 and deforms to cover the mating end 11, the core needle 6 in the shielding strip 2 is also located in the insertion groove 113. When the buckle 1 is subjected to pipeline pressure, causing the mating end 11 and the insertion end 12 to generate a pulling force that moves them away from each other, the core needle 6 can be embedded in the mating hole 114 to further improve the tensile strength of the connection of the buckle 1 and improve the fixing stability of the buckle 1.

[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
