DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings.

[0020] according to Figure 1-Figure 4 As shown, the embodiment of the present application proposes a new type of fixing structure of an aluminum frame luggage, including an aluminum frame 1 and a box shell 2, the aluminum frame 1 is provided with a clamping groove 5, the two opposite inner walls of the clamping groove 5 are respectively a first abutting surface 6 and a second abutting surface 7, the box shell 2 is provided with a clamping end, the clamping end extends into the clamping groove 5 and abuts the first abutting surface 6, an elastic locking member is provided between one end of the clamping end away from the first abutting surface 6 and the second abutting surface 7; the elastic locking member includes a clamping plate 3, the clamping plate 3 is provided with a third abutting surface 15 and a fourth abutting surface 14, the third abutting surface 15 abuts one end of the clamping end away from the first abutting surface 6, the fourth abutting surface 14 abuts the second abutting surface 7, the clamping plate 3 is also provided with an elastic limit The positioning plate 4, the above-mentioned clamping end is provided with a recessed portion 16 abutting against the above-mentioned elastic limiting plate 4; the above-mentioned clamping groove 5 is a rectangular installation gap provided in the above-mentioned aluminum frame 1. During the specific installation process, the above-mentioned clamping plate 3 is first placed in the above-mentioned clamping groove 5, and at this time, the fourth abutting surface 14 of the clamping plate 3 contacts the above-mentioned second abutting surface 7, and at this time, the clamping end is extended into the above-mentioned clamping groove 5 and the clamping end is clamped by the first abutting surface 6 and the third abutting surface 15, and a stable connection is ensured under the action of friction. At the same time, during the extension process, the elastic limiting plate 4 is compressed by the clamping end until the elastic limiting plate 4 is clamped into the above-mentioned recessed portion 16, and the elastic limiting plate 4 is in a state of naturally abutting against the limiting portion, so that the aluminum frame 1 and the box shell 2 form a stable fixed structure with each other, and the entire installation process is relatively simple and the installation efficiency is high.

[0021] It is worth noting that the third abutting surface 15 of the clamping plate 3 abuts against the first abutting surface 6, the fourth abutting surface 14 abuts against the second abutting surface 7, and the limiting structure of the elastic limiting plate 4 and the recessed portion 16 enables the aluminum frame 1 and the box shell 2 to achieve a clamped and locked fit to ensure the stability of the connection, and the entire installation process is to place the clamping plate 3 in the clamping groove 5, and then extend the clamping end into the clamping groove 5, and through the action of force, the two sides of the clamping end respectively abut against the first abutting surface 6 and the third abutting surface 15, and through the elastic force, the elastic limiting plate 4 abuts against the recessed portion 16 to achieve a stable fixing effect, the entire installation process does not require other steps, the installation process is simple and convenient, and the efficiency of the entire installation process is improved.

[0022] Specifically, the third abutting surface 15 is provided with an elastic sheet for abutting the first abutting surface 6. In the working state, the elastic sheet is flattened by the first abutting surface 6 and is flush with the third abutting surface, so that the first abutting surface 6 abuts against the elastic sheet and the third abutting surface 15 at the same time. In other words, when the clamping end is inserted into the gap between the first abutting surface 6 and the third abutting surface 15, the elastic sheet abuts against the first abutting surface 6 and undergoes elastic deformation. Specifically, the elastic sheet is tilted toward the clamping groove 5. When the clamping end is fully inserted into the clamping groove 5, the elastic sheet is compressed to be flush with the third abutting surface 15. The abutting force of the elastic sheet improves the fixing strength of the clamping end.

[0023] The above-mentioned clamping end includes a bending section 8 and a straight section 9 which are sequentially connected to the above-mentioned box shell 2. The two ends of the above-mentioned straight section 9 respectively abut the above-mentioned first abutting surface 6 and the above-mentioned third abutting surface 15, and the above-mentioned bending section 8 is bent toward the above-mentioned second abutting surface 7. The above-mentioned recessed portion 16 is the bending portion of the above-mentioned bending plate close to the above-mentioned second abutting surface 7. Specifically, the fixed end of the above-mentioned box shell 2 is provided with a bending section 8, and the bending section is connected with a straight section 9 parallel to the box shell 2. Moreover, the bending design of the bending section 8 and the straight section 9 enables the straight section 9 to be clamped into the clamping groove 5 closely so that the outer wall of the aluminum frame 1 and the box shell 2 are flush. In the specific installation structure, after the straight section 9 is fully extended into the clamping groove 5 to achieve stable clamping, the end of the elastic limiting plate 4 away from the above-mentioned clamping plate 3 stably abuts against the bending portion of the bending plate close to the above-mentioned second abutting surface 7, so that the entire box shell 2 is locked and limited, ensuring the stability of the entire fixed structure.

[0024] Specifically, the clamping plate 3 includes a first straight plate 10, one end of the first straight plate 10 extending toward the clamping groove 5 is connected to a first inclined plate 11 extending obliquely toward the first abutting surface 6 and toward the inner direction of the clamping groove 5, one end of the first inclined plate 11 away from the first straight plate 10 is connected to a second straight plate 12, one end of the second straight plate 12 away from the first inclined plate 11 is provided with a second inclined plate 13 extending toward the second abutting surface 7 and abutting against the second abutting surface 7, the third abutting surface 15 is provided on a side of the second straight plate 12 close to the first abutting surface 6, and the elastic limiting plate 4 is connected to a side of the first straight plate 10 away from the second abutting surface 7. The fourth abutment surface 14 is arranged on the side of the first straight plate 10 close to the first abutment surface 6. In the specific installation structure, the first straight plate 10 is flush with the second abutment surface 7 and abuts against each other. The first inclined plate 11 is inclined and extends toward the first abutment surface 6. When it extends to the position of the straight section 9, it is connected to the second straight plate 12. The second straight plate 12 is flush with the surface of the side of the straight section 9 away from the first abutment surface 6 and abuts against each other. A second inclined plate 13 is arranged on the end of the second straight plate 12 away from the first inclined plate 11. The second inclined plate 13 extends toward the second abutment surface 7, and the end of the second inclined plate 13 away from the second straight plate 12 abuts against the innermost edge of the clamping groove 5 to ensure the stability of the entire clamping plate 3.

[0025] The above-mentioned elastic limiting plate 4 is an elastic plate obliquely arranged on the above-mentioned first straight plate 10. The above-mentioned elastic plate is compressed when the straight section 9 extends into the clamping groove 5 and slides relative to the surface of the straight section 9. When sliding to the position of the bending section 8, the elastic plate loses a certain abutting force and is directly stuck in the bending part of the bending section 8, so that when the force is applied to the box shell 2 away from the clamping groove 5, the elastic plate abuts against the position of the bending section 8 to achieve a stable clamping effect. Moreover, under the clamping action and friction force of the first abutting surface 6 and the third abutting surface 15, the entire fixed structure of the straight section 9 is relatively stable.

[0026] In order to further ensure the clamping stability of the entire clamping plate 3, the second abutting surface 7 is also provided with a limiting groove, and the end of the first straight plate 10 away from the first inclined plate 11 abuts against the edge of the limiting groove, and the third abutting surface 15 abuts against the inner wall of the limiting groove. When a force is applied to the entire clamping plate 3 away from the clamping groove 5, the first straight plate 10 of the clamping plate 3 is clamped with the edge of the limiting groove to achieve good positioning and clamping effects.
