Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 These are frontal, oblique, and top views of the double corrugated pipe fastening buckle of this utility model, as well as detailed structural diagrams.

[0024] Reference Figure 1 and Figure 2 The present invention provides a fastening buckle for a double corrugated pipe, comprising a buckle base 1, a buckle frame 2, and a connector 3 fixedly disposed on the upper end of the buckle frame 2.

[0025] The upper end of the card holder 1 is provided with three sets of grooves 9. The outer pins 8 are movably set in the two side grooves 9, and the inner pins 8 are all set in the middle groove 9. The contact surfaces of the pins 8 and the grooves 9 are all designed with arc-shaped surfaces. The upper end of the middle groove 9 is fixedly connected with a fixing pin 10, and the two sets of inner pins 8 are located on both sides of the fixing pin 10.

[0026] The bottom of the inner pin 8 is fixedly connected to a pin clip 801, and the pin clip 801 engages with the outer side of the fixing pin 10.

[0027] One side of the card holder 1 is fixedly connected to the card frame 2 by a connecting piece 5. A fixed card head 7 is fixedly connected to the upper end of the other side of the card holder 1, and a movable elbow 6 that is engaged with the fixed card head 7 is fixedly connected to the same side of the card frame 2.

[0028] The card frame 2 has two sets of symmetrical corrugated pipe grooves 4 running through it, and the part of the card frame 2 located at the bottom of the corrugated pipe grooves 4 is provided with pins 8.

[0029] The card frame 2 has a pressure-resistant groove 201 fixedly installed through its front end near the top, and pressure-resistant ribs 202, serving as structural reinforcement, are fixedly installed on both sides of the upper end of the card frame 2. In practical use, if the fastening buckle is subjected to excessive outward pressure from the inside, the pressure-resistant groove 201, due to its internal control, can act as a buffer, indirectly protecting the card frame 2. Conversely, if the fastening buckle is subjected to inward pressure from the outside, the pressure-resistant ribs 202 on both sides, due to their reinforcing effect, can also act as a buffer, indirectly protecting the card frame 2. Furthermore, the hollow portion of the pressure-resistant groove 201 also reduces the overall weight and cost.

[0030] The inner wall of the corrugated pipe groove 4, which runs through the inside of the frame 2, is uniformly provided with washers 401. On the one hand, the washers 401 can make frictional contact with the corrugated pipe body, providing an auxiliary anti-slip and stabilizing effect. On the other hand, the washers 401 can reduce the wear on the contact surface of the corrugated pipe when the whole corrugated pipe is tightened, thus providing a protective effect. At the same time, the washers 401 also have a certain sealing effect, which can achieve the optimal solution for the connection of the corrugated pipe.

[0031] Reference Figure 3 The connector 3 has an open design at the top and around the edges. The connector 3 has a connecting piece 301 fixedly connected inside the openings on the front and back sides. The connecting piece 301 is made of elastic material and has multiple sets of protruding locking ridges 302 on the outer side.

[0032] The main body of the fastening buckle is made of polyester resin, which has good ductility and thermal stability; alternatively, it can be made of polypropylene substrate, which offers the advantages of lighter weight and higher molding efficiency. The connecting piece 301, connecting piece 5, movable elbow 6, and pin 8 are all made of elastic metal, and the washer 401 is made of rubber. Thus, the fastening buckle of this utility model has the excellent synergistic effect of multiple materials: for example, the PC / ABS alloy combines the rigidity of polycarbonate with the toughness of ABS, and has a higher tolerance for the thickness of the corrugated pipe.

[0033] Based on the above structural design, when the clamp 2 is used to fasten double corrugated pipes with a thickness range of 1.0-5.0mm, the connecting piece 5, movable elbow 6, and pin 8 in the upper buckle can be extended or adjusted to adjust their angles accordingly, thereby matching the corrugated pipes with a thickness range of 1.0-5.0mm for fastening.

[0034] During the installation of connector 3, due to the elastic design of connecting piece 301, the operator can pre-press connecting piece 301 to retract it into the opening on the outside of connector 3. Then, connector 3 is inserted, and the elastic recovery of connecting piece 301 causes the outer retaining ridge 302 to engage at the connection position, thus achieving the overall engagement and installation of connector 3 and fastening buckle to fix the corrugated pipe in place. During subsequent disassembly, pressing connecting piece 301 at the connection position retracts it into the opening, allowing connector 3 to be stretched and pulled out. This allows the corrugated pipe to be moved or even removed.

[0035] The new type of fastening buckle is used to insert or remove the corrugated pipe, which relies on the structural design of the connecting piece 5 and the frame 2.

[0036] When using the fastening buckle of this utility model, refer to... Figure 1 The operator can open the card frame 2 at the top of the card holder 1 by bending the connecting piece 5.

[0037] During the process of opening card frame 2, please refer to the attached document. Figure 4 At this point, the operator needs to manually move the two sets of pins 8 on the inner side so that the pin clips 801 connected to the outer side of the two sets of pins 8 on the inner side are disengaged from the locking pins 10 in the middle groove 9, thus separating the pins 8 from the locking pins 10, and then the card frame 2 can be opened smoothly.

[0038] During the closing of the frame 2, the two sets of corrugated pipes are placed in the two sets of corrugated pipe grooves 4 inside the frame 2, and then the frame 2 is closed. During the closing of the frame 2, the operator presses the side of the frame 2 close to the movable elbow 6. At this time, the movable elbow 6 is pressed down, and the inclined surface at the bottom contacts the inclined surface of the fixed clamp 7 at the upper end of the clamp seat 1. The two are locked together again. During the pressing of the frame 2, the pin 8 that was opened at the beginning of the cup is also pressed down. The pin 8 contacts the upper end of the fixed clamp 10 and bends, causing the pin clamp 801 to tilt past the upper end of the fixed clamp 10 and lock together with the fixed clamp 10 again, thus completing the complete tightening of the corrugated pipe.

[0039] In this process, since the gasket 401 on the inner wall of the corrugated pipe groove 4, as well as the connecting piece 5, the movable elbow 6 and the pin 8 are all made of elastic metal material, which has extensibility and the gasket 401 can be squeezed, it can be used to fasten corrugated pipes with a plate thickness range of 1.0-5.0mm.

[0040] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.

[0041] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
