[0019] Example 1

[0020] like Figure 1 and Figure 2As shown in the figure, this embodiment proposes a buckle for connecting a double-socket structure wall pipe and a sleeve. The buckle is buckle 1, which includes a buckle body. Both ends of the buckle body have two upward-facing notches 101. A buckle plate 12 is formed between the two notches 101 on the same side. A protruding buckle 13 is integrally connected to the outer side of the buckle plate 12. The buckle body has a groove 1 on its inner side. The groove 1 opens upward, which is conducive to the deformation of the buckle plate 12 inward. The design of the groove 1 also reduces the material used in the production of this buckle, saving costs. The groove 1 has a rib 15 integrally connected to the buckle body in the middle, which can improve the structural strength of the entire buckle 1. At the same time, the rib 15 divides the groove 1 of the buckle 1 into left and right sides, which makes it convenient for workers to insert their fingers into the grooves on both sides and pinch the rib 15 to install or remove the buckle 1, improving the convenience of operation.

[0021] The baffle section 14 is equipped with arrows and text markings indicating the installation direction, as well as the applicable pipe diameter specifications for the clip 1. Based on the above information, it can assist workers in accurately clipping the clip 1 onto the sleeve and inserting it into the trough of the corrugated pipe to effectively limit the corrugated pipe inside the sleeve.

[0022] like Figure 1 As shown, the lower part of the buckle body has inclined surfaces 11 on both sides, which gradually taper towards the bottom. When the buckle body is snapped downwards into the pre-drilled holes on the sleeve, the inclined surfaces 11 on both sides guide the snapping process, making it easy to insert the buckle 1 into the holes. The bottom surface of the protruding buckle part 13 gradually slopes upwards away from the buckle plate part 12. During the insertion of the buckle 1 into the hole, the bottom surface of the protruding buckle part 13 slides along the outer end of the hole. The sleeve presses the buckle plate part 12 inwards through the protruding buckle part 13, causing the buckle plate part 12 to deform inwards. After the buckle 1 is installed in place, the buckle plate part 12 rebounds, and the protruding buckle part 13 is locked inside the sleeve at the edge of the hole. The bottom end of the buckle 1 extends into the trough of the corrugated pipe for limiting.

[0023] like Figure 1 As shown, the top of the buckle body has extended baffle portions 14 on both sides in the width direction. The baffle portions 14 are arc-shaped to fit against the circumferential surface of the sleeve, preventing excessive protrusion relative to the sleeve and limiting the snap-on of the buckle 1. When the baffle portions 14 are attached to the outer circumferential surface of the sleeve, the protruding buckle portion 13 is also snapped into place.

[0024] Example 2

[0025] like Figure 3 and Figure 4As shown in the figure, this embodiment proposes a snap fastener for connecting a double-socket wall pipe and a sleeve. The snap fastener is snap fastener 2, which includes a snap body portion and two symmetrically distributed secondary snap fastener portions. A connecting plate portion 25 is integrally connected between the top ends of the two secondary snap fastener portions, and a gap area 251 is formed between the two secondary snap fastener portions and the connecting plate portion 25. Each snap fastener 2 corresponds to two pre-reserved locking holes on the sleeve, and two secondary snap fastener portions are respectively locked into the two locking holes. The snap fastener 2 is generally U-shaped and can be securely locked into the sleeve. The outer ends of the two secondary snap fastener portions each have two upward-facing notches 201, that is, each secondary snap fastener portion has two notches 201 at only one end, which is the outermost end of the two secondary snap fastener portions facing away from each other. A snap-on portion 22 is formed between two notches 201 on the same side. A protruding snap-on portion 23 is integrally connected to the outer side of the snap-on portion 22. Both sides of the top of the snap-on portion have extended baffle portions 24 in the width direction, that is, both sides of the width direction of the two secondary snap-on portions have extended baffle portions 24. The baffle portions 24 are arc-shaped and position the snap-on portion 2 on the sleeve. The baffle portions 24 are connected to the connecting plate portion 25 and have the same curvature, so that they can be adaptively fitted to the circumferential surface of the sleeve.

[0026] The inner side of the secondary buckle has a second groove, with the opening of the second groove facing upwards, so that the second buckle plate 22 can deform inwards. Workers can insert their fingers into the two second grooves respectively, pinch the two secondary buckles, and install or remove the second buckle 2, making it easy to apply force and facilitating assembly and disassembly. The design of the second groove also reduces the material used in the production of this buckle, saving costs.

[0027] like Figure 3 As shown, both sides of the lower part of the secondary buckle have inclined surfaces 21 that gradually converge towards the bottom to guide the insertion of the buckle 2 into the pre-drilled holes on the sleeve, thus improving the ease of installation.

[0028] The bottom surface of the second buckle part 23 gradually slopes upward away from the second buckle plate part 22. During the process of the second buckle part 22 being inserted into the pre-drilled hole on the sleeve, the edge of the hole pushes the second buckle plate part 22 inward through the second buckle part 23. The second buckle plate part 22 deforms inward. After the second buckle part 22 is installed in place, the second buckle plate part 22 rebounds, and the second buckle part 23 is stuck on the inner wall of the sleeve on one side of the bottom end of the hole. The lower part of the second buckle part 2 extends into the trough of the corrugated pipe inside the sleeve, limiting the corrugated pipe.

[0029] like Figure 3 As shown, the baffle part 24 is provided with arrows and text markings indicating the installation direction, as well as the pipe diameter specifications applicable to the clip 2. Based on the above indication information, it can assist the worker in accurately clipping the clip 2 onto the sleeve and inserting it into the trough of the corrugated pipe to effectively limit the corrugated pipe inside the sleeve.

[0030] like Figure 5As shown, the sleeve has two rings of pre-reserved multiple locking holes on both sides. Two bellows extend into the inside of the sleeve from both sides, and then the two rings of multiple locking buckles are used to lock them into the locking holes and extend into the trough of the bellows for limiting.

[0031] Both types of buckles of this utility model can act independently on the sleeve and the bellows. They are snapped onto the sleeve by a snap-fit ​​connection and extend downwards to the trough of the bellows for limiting. Each bellows has at least one ring of multiple buckles at one end to connect with the sleeve, ensuring a reliable connection between the sleeve and the bellows. The buckles are easy to disassemble, which is convenient for the maintenance or replacement of the bellows.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
