Please refer to Fig. 6 for further cooperation. The aforesaid tripod assembly 30 includes a bipod 31, a horizontal link 32 and two support arms 33; On the two ends of crossbeam 21 and can corresponding box body 10 open, and be provided with a torsion spring 311 at the pivotal place of each tripod 31, the two ends of this torsion spring 311 are connected on crossbeam 21 and tripod 31 respectively, and then Increase the friction force when the tripod 31 corresponds to the opening of the cabinet 10 and provide the reset force that the tripod 31 automatically fits toward the cabinet 10. The lower ends of the tripod 31 are respectively provided with an auxiliary wheel 312. When opening, the user can tilt the box body 10 toward the rear side so that the auxiliary wheel 312 of the tripod 31 falls on the ground, and the auxiliary wheel 312 cooperates with the main wheel 222 at the bottom end of the pillar 22 to replace the roller 11 at the bottom end of the box body 10. For support and transportation;

Please refer to Figure 7 and Figure 8 for further cooperation. The horizontal connecting rod 32 is connected between the two legs 31, and a main locking block 321 and a secondary locking block 322 are arranged on it; the main locking block 321 is located on the horizontal connecting rod. 32 and extends towards the box body 10, which corresponds to the bottom end of the main lock bar 24, and a main lock hole 3211 is penetrated through the block so that it is sleeved on the main lock bar 24 when the tripod 31 is folded. The bottom end, and then fix the tripod 31, and the extended end of the main lock block 321 can be slightly bent downwards, so that in the action of retracting the tripod 31, the curved extended end first contacts the bottom end of the main lock bar 24, and The bottom end of the main lock bar 24 is pushed upward against the spring 245, and then when the main lock hole 3211 moves to the bottom end of the main lock bar 24, the main lock bar 24 is penetrated into the main lock hole 3211 by the restoring force of the spring 245 among;

The auxiliary locking block 322 is arranged on the rod body of the horizontal connecting rod 32 and extends toward the box body 10, which corresponds to the bottom end of the auxiliary locking rod 25, and a auxiliary locking hole 3221 is formed on the block for when the tripod 31 is folded. Correspondingly located at the bottom of the secondary locking lever 25, so that when the tripod 31 is closed, the user can press down the secondary locking lever 25 so that the bottom end of the secondary locking lever 25 can pass through the secondary locking hole 3221 to achieve fixation. The function of tripod 31.

The support arm 33 is connected between the pillar 22 and the cross link 32 to limit the maximum pivot angle of the stand 31, and it may further include a front link 331 and a rear link 332, and one end of the front link 331 is pivotally mounted on Strut 22, one end extends backward, one end of rear link 332 is pivotally connected with the extension end of front link 331, and the other end of rear link 332 is pivotally arranged on cross link 32, and on the rear link 332 is close to A limit block 3321 can be provided at the pivot point of the front link 331, which is used to limit the relative pivoting of the two links 331, 332 and make the pivot angle less than 180 degrees. The limit block 3321 is formed on the rear link 332 The shaft extends transversely across the shaft of the front link 331, so as to abut against the shaft of the front link 331 during the relative pivoting action of the front and rear links 331, 332 so as to limit the maximum angle of pivoting. , and limit the maximum pivoting angle of the two connecting rods 331, 332 to less than 180 degrees, which can prevent the folding action of the tripod 31 from being unable to move from the outer ends of the connecting rods 331, 332 because the two connecting rods 331, 332 are horizontal. Directly push inward to fold the two connecting rods 331, 332 relative to each other.

In the utility model, after the tripod 31 is opened and the box body 10 is tilted backward, the overall center of gravity can be stably placed between the auxiliary wheel 312 of the tripod 31 and the main wheel 222 at the bottom of the pillar 22, so that the user can There is no need to apply additional force to maintain its inclination angle, so it can save force and be easy to operate;

Furthermore, when the user wants to temporarily close the tripod 31, the tripod 31 can be fixed by the main locking lever 24, and the user only needs to lift the handle 241 of the main locking lever 24 to make the main locking lever The bottom end of 24 breaks away from the main lock block 321 to untie the fixation; and because the design of the main lock bar 24 is mainly to temporarily locate the tripod 31, so its fixation may also be released due to vibration or shaking, and the utility model goes further Provide the user with a design in which the tripod 31 can be stably positioned by the secondary locking lever 25 .
