These two interior clips are unique to the present invention: an adjustable doghouse seat 8 and a tree-shaped rivet clip 9, which are described below.

[0107] like Figures 12A-12C As shown, the adjustable dog kennel seat 8 is composed of a dog kennel seat 81, a dog kennel seat cushion block 82, and a capped buckle 83. The dog kennel seat 81 has a characteristic structure of an arched mounting portion 811 and a base 812. The arched mounting portion 811 has an arched surface and a hollow interior, in which a supporting rib is provided. One side of the arched mounting portion 811 has an opening 811a, and a dog kennel mating hole 811b is provided at the top center. A notch 811c is provided on one side of the dog kennel mating hole 811b. The dog kennel mating hole 811b is connected to the opening 811a through the notch 811c. The connection between the notch 811c and the dog kennel mating hole 811b has a snap-fit ​​edge to close the notch, and the connection between the notch 811c and the opening 811a has a guide edge to open the notch. In addition, a dog kennel rib 811d is provided on each side of the notch 811c. The dog kennel rib 811d is two small protrusions.

[0108] The arched mounting portion 811 is fixed to the base 812, the bottom of which is connected to the dog kennel seat cushion 82. The base 812 has a bottom groove 812a, which is used to apply adhesive to the dog kennel seat cushion 82 to enhance the strength of the adjustable dog kennel seat 8. The dog kennel seat cushion 82 is used to adjust the height of the dog kennel seat. Depending on the installation location, the dog kennel seat cushion 82 can be made of different materials.

[0109] The hooded buckle 83 has a characteristic structure of a small buckle cap 83a, a buckle fitting shaft 83b and a large buckle cap 83c. The small buckle cap 83a and the large buckle cap 83c are connected by the buckle fitting shaft 83b. When the hooded buckle 83 is installed in conjunction with the doghouse seat 81, the hooded buckle 83 is sent into the doghouse fitting hole 811b along the opening 811a and the notch 811c of the arched mounting portion 811. The small buckle cap 83a is located below the doghouse fitting hole 811b, and the large buckle cap 83c is located above the doghouse fitting hole 811b. The buckle fitting shaft 83b forms a clearance fit with the doghouse fitting hole 811b. The clearance is about 1mm, which is convenient for installation. After installation, the doghouse rib 811d has a limiting effect on the large buckle cap 83c, preventing the hooded buckle 83 from falling out of the fitting hole. During the assembly process, the notch 811c and The guide edge of the opening 811a serves as a guide to facilitate the snap-fitting shaft 83b to be snapped in; The engaging edge where the opening 811c meets the doghouse mating hole 811b acts as a latch for the snap-fit ​​shaft 83b, preventing it from falling out. The small snap cap 83a and the large snap cap 83c are pressed against the upper and lower surfaces of the arched mounting portion 811, increasing the contact area and mounting strength. The large snap cap 83c is connected to the component to be connected.

[0110] like Figures 13A-13B As shown, the tree-shaped rivet clip 9 is composed of a tree-shaped buckle 91 and a tree-shaped rivet seat 92. The tree-shaped buckle 91 has a tree-shaped buckle cap 911, a tree-shaped buckle barb 912, and a tree-shaped buckle cone angle 913. The tree-shaped buckle cap 911 has a cap end and a rod end. The rod end is provided with tree-shaped buckle barbs 912. The tree-shaped buckle barbs 912 are arranged in circles along the length of the rod, and a barb notch 912A is provided on each circle of tree-shaped buckle barbs 912. The purpose of providing the barb notch is to provide space for the barbs to deform. A tree-shaped buckle cone angle 913 is provided on the head of the rod end. The tree-shaped rivet seat 92 has a rivet seat hole 921, a rivet seat bonding surface 922, and a rivet seat clamping surface 923. The rivet seat hole 921 penetrates the tree-shaped rivet seat, with a larger opening area near the rivet seat bonding surface 922 and a smaller opening area near the rivet seat clamping surface 923. During assembly, the tree-shaped clip 91 is inserted from the bottom of the tree-shaped rivet seat 92, and finally the cap end of the tree-shaped clip cap 911 remains in the rivet seat hole 921. The tree-shaped clip barbs 912 on the rod end are clamped on the rivet seat clamping surface 923 using their own barbs. The tree-shaped clip cone angle 913 at the head of the rod end is used to drill into the part to be connected, which is conducive to installation and positioning. A cavity is formed between the rivet seat hole 921 and the tree-shaped clip cap 911. Adhesive is applied to the cavity to improve the bonding strength of the tree-shaped rivet clip 9. The rivet seat bonding surface 922 is installed at the selected position with adhesive.

[0111] The adjustable doghouse base 8 and the tree-shaped rivet clip 9 in the present invention are designed according to the structure and can be applied to other interior structures. The adjustable doghouse seat 8 or the tree-shaped rivet clip 9 are used in a large number of structural joints, and are all bonded to the position where they need to be installed by adhesive. The strength of the adhesive is sufficient to ensure that the installation is firm and can be repeatedly disassembled. Both of the above-mentioned clip fixing methods for interior decoration are invisible from the outside. During production and assembly, only one direction needs to be tapped, which makes installation convenient and efficient. In particular, the tree-shaped rivet clip 9 can be used for thick material installation. Since the modified interior decoration parts of the present invention are all covered, the gap left between the parts is the space of the covered leather.
