[0031] Example 1

[0032] Reference Figure 1-Figure 4 , is the first embodiment of the utility model, which provides a bracket mechanism with adjustable length, including a bracket component 100, including a bracket assembly 101, a locking assembly 102 arranged on the outer wall of the bracket assembly 101, and a locking assembly 103 installed on the locking assembly 102; and a locking component 200, including an adjustment assembly 201 arranged on the bracket assembly 101, a switch assembly 202 arranged on the bracket assembly 101, and a rebound assembly 203 installed on the bracket assembly 101.

[0033] Specifically, a locking assembly 102 is fixedly installed on the outer wall below the bracket assembly 101, and a locking assembly 103 is fixedly installed on the locking assembly 102. The locking assembly 102 is used in conjunction with the locking assembly 103 to adjust the length of the bracket assembly 101, so that the storage box 301a can be placed in an unstable place.

[0035] Specifically, limiting grooves 101b are symmetrically provided on both sides of the inner wall below the sleeve 101a, and a pressing hole 101c is provided on the outer wall of the sleeve 101a, and the pressing hole 101c is arranged between the two limiting grooves 101b, wherein a cylindrical support leg 101d is provided on the inner wall of the sleeve 101a, and a limiting block 101e is fixedly installed on the top of the support leg 101d, and the limiting block 101e is used in conjunction with the limiting groove 101b to prevent the support leg 101d from detaching from the sleeve 101a when sliding in the sleeve 101a, and a positioning groove 101f is provided on the outer wall of the support leg 101d, and the position of the positioning groove 101f corresponds to the pressing hole 101c.

[0036] Furthermore, the locking assembly 102 includes a locking ring 102a arranged on the outer wall of the sleeve 101a, a connecting rod 102b installed on the locking ring 102a, a pressing column 102c arranged on the outer wall of the connecting rod 102b, a pressing block 102d arranged below the pressing column 102c, a pressing plate 102e installed at the bottom of the pressing block 102d, a telescopic column 102f installed on the pressing plate 102e, and a return spring 102g arranged on the outer wall of the telescopic column 102f.

[0037] Specifically, the part where the locking ring 102a is fixedly connected to the bottom of the sleeve 101a is an annular structure, and two baffles are fixedly connected to the outer wall of the locking ring 102a, and a connecting rod 102b is fixedly connected between the two baffles, and a pressing column 102c is rotatably connected to the outer wall of the connecting rod 102b, and the center of the pressing column 102c deviates from the center of the connecting rod 102b, and a pressing block 102d is arranged below the pressing column 102c, and a pressing plate 102e is fixedly connected to the bottom of the pressing block 102d, and telescopic columns 102f are fixedly connected between the two sides of the pressing plate 102e and the inner wall of the sleeve 101a, and a return spring 102g is arranged on the outer wall of the telescopic column 102f, and the return spring 102g is fixedly connected between the pressing plate 102e and the inner wall of the sleeve 101a.

[0038] Furthermore, the locking assembly 103 includes a connecting rod 103a installed on the outer wall of the pressing column 102c, a protrusion 103b installed on the connecting rod 103a, and a clamping block 103c installed on the outer wall of the locking ring 102a.

[0039] Specifically, the outer wall of the pressing column 102c is fixedly connected with a connecting rod 103a, and the bottom of the connecting rod 103a away from the pressing column 102c is fixedly connected with a protrusion 103b, wherein the outer wall of the locking ring 102a is fixedly connected with a clamping block 103c, and the position of the clamping block 103c corresponds to that of the protrusion 103b.

[0040] Operation process: When in use, the protrusion 103b blocks the block 103c on the connecting rod 103a. At this time, the positioning groove 101f on the supporting leg 101d is squeezed by the pressing plate 102e, and the supporting leg 101d cannot move inside the sleeve 101a. When the storage box 301a is placed on an uneven position such as a bed, the supporting leg 101d at a higher or lower position is selected, and the connecting rod 103a is rotated to make the protrusion 103b away from the block 103c. The connecting rod 103a drives the pressing column 102c to rotate, and the center of gravity of the pressing column 102c is offset, so that the force on the reset spring 102g disappears, and the reset spring 102g rebounds to drive the pressing column 102c to rotate. The pressing plate 102e is away from the positioning groove 101f. At this time, the telescopic length of the leg 101d can be controlled. When it moves to an appropriate length to keep the storage box 301a horizontal, the connecting rod 103a is rotated to make the protrusion 103b engage with the block 103c. During this process, the pressing column 102c rotates and the center of gravity moves downward. The pressing column 102c presses the pressing block 102d, driving the pressing plate 102e to squeeze the positioning groove 101f and fix the position of the leg 101d. The length of the leg 101d can be adjusted at will, so that the storage box 301a can be placed in any unstable place to prevent the storage box 301a from tipping over and causing pollution.
