[0024] Reference example Figures 1 to 3 A fixing buckle for a heat shrinkable tube winding disc includes a support portion 1. A clamping portion 2 for clamping a disc 7 is provided on the opposite side of the support portion 1. A hook portion 3 is provided on the end face of the support portion 1. An elastic portion 4 is provided on the opposite side of the hook portion 3. A plurality of convex portions 41 are provided on both sides of the inner wall of the elastic portion 4 and are arranged in an interlaced manner. A buckle block 42 is provided at the head of the elastic portion 4 and is buckled inside the hook portion 3 to fix the heat shrinkable tube between the elastic portion 4 and the hook portion 3.

[0025] It is worth mentioning that a connecting portion 5 is provided on one side of the support portion 1 and the clamping portion 2, and a notch 6 for the disc 7 to enter is provided on the other side of the support portion 1 and the clamping portion 2. The connecting portion 5 not only plays a role in energy storage, but also forms a spacing for clamping the disc 7 between the support portion 1 and the clamping portion 2.

[0026] It is worth mentioning that a plurality of inclined blocks 11 are provided on the inner end face of the support portion 1 and are arranged in an interlaced manner. The inclined direction of the inclined blocks 11 faces the notch 6. Inclined guiding surfaces 12 are provided on both sides of the entrance of the support portion 1. The inclined blocks 11 increase the friction between the support portion 1 and the disc 7. The inclined direction of the inclined blocks 11 facing the notch 6 is to facilitate the insertion of the support block and the clamping portion 2 on the disc 7. When an outward pulling force is applied, the inclined blocks 11 will generate a large friction with the disc 7 to prevent the fixing buckle from detaching from the disc 7 during the transportation or vibration of the winding disc. The guiding portion enables the disc 7 to first abut against the clamping portion 2, and then apply a thrust to the fixing buckle to gradually open the notch 6 by the disc 7.

[0027] It is worth mentioning that the head of the hook portion 3 is provided with an operating portion 31, the hook portion 3 is provided with a buckle groove 32, the head of the buckle groove 32 is provided with a resisting portion 33, the hook portion 3 includes a pressure-bearing portion 34, a reinforcing rib 35 between the back of the pressure-bearing portion 34 and the support portion 1, and a raised action portion 36 is provided on the front of the pressure-bearing portion 34. By applying a thrust to the operating portion 31, the entrance of the hook groove is gradually expanded until the resisting portion 33 leaves the buckle block 42, the reinforcing rib 35 strengthens the connection stability between the pressure-bearing portion 34 and the support portion 1, and provides strong support for the pressure-bearing portion 34. The action portion 36 makes the force of the elastic portion 4 acting on it more concentrated, further improving the connection stability between the heat shrink tube and the fixed buckle;

[0028] It is worth mentioning that the elastic part 4 is provided with a bent part 43, the bent part 43 is connected to the support part 1 by injection molding, the convex part 41 is arranged on both sides of the pressure-bearing part 34, and the bent part 43 plays the role of energy storage;

[0029] It is worth mentioning that the buckle block 42 abuts against the abutting portion 33 . When the buckle block 42 and the abutting portion 33 abut against each other, a locking holding point is formed, and the reaction force of the elastic portion 4 makes the buckle block 42 and the abutting portion 33 tightly connected.

[0030] The use principle of the utility model is now described as follows:

[0031] Align one foot of the notch 6 with the disc 7, and make the disc 7 enter between the support part 1 and the clamping part 2 through the inclined guide part. The clamping part 2 is subjected to the expansion force of the disc 7 and first stores energy and then releases the force, so that the clamping part 2 acts on the disc 7 and presses the disc 7 tightly against the inclined block 11, thereby increasing the friction between the support part 1 and the disc 7 and ensuring that the support part 1 is fixed in the position after the movement;

[0032] Place a section of the heat shrink tube between the pressure-bearing portion 34 and the elastic portion 4, push the elastic portion 4 to press the heat shrink tube against the action portion 36, and the buckle block 42 enters the hook groove and abuts against the abutment portion 33. At this time, the heat shrink tube is concave and is pressed tightly against the interlaced convex portions 41, increasing the friction between the heat shrink tube and the elastic portion 4, ensuring a stable connection between the heat shrink tube and the buckle.

[0033] The above design scheme can make the product have the advantages of repeated use, convenient wire fixing and stable wire bundle.

[0034] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
