[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1: Please refer to Figure 1-4A telescopic cabinet with adjustable internal space includes a left cabinet 1 and a right cabinet 9. The right cabinet 9 is located on the right side of the left cabinet 1. Threaded blocks 13 are welded to the bottom right side of the left cabinet 1 and the bottom left side of the right cabinet 9. Holes 14 are provided between the two sides of the bottom of the threaded blocks 13. A threaded rod 11 is horizontally assembled between the threaded blocks 13. Fixing sleeves 17 are installed on the bottom surfaces of the left cabinet 1 and the right cabinet 9. Holes 15 are provided between the two sides of the bottom of the fixing sleeves 17. Limiting rods 12 are horizontally inserted between holes 14 and holes 15. Turning wheels 10 are installed at the corners of the bottom of the left cabinet 1 and the right cabinet 9. A folding sleeve 6 is fixed at the center between the left cabinet 1 and the right cabinet 9.
[0025] The lead screw 11 passes through the fixed sleeve 17 but is not engaged with it. The external texture of the lead screw 11 matches the inner wall of the threaded block 13. Hole 14 and hole 2 15 are on the same horizontal plane. The limiting rod 12 restricts the movement of the threaded block 13 and the fixed sleeve 17.
[0026] Specifically, such as Figure 1 and Figure 2 As shown, the left cabinet 1 and the right cabinet 9 are connected by a folding sleeve 6 at the center. Then, by rotating the screw 11 installed between the bottom threaded blocks 13, the left cabinet 1 and the right cabinet 9 with threaded blocks 13 are pushed laterally between the fixed sleeves 17 on both sides. Because the hole 14 and the hole 2 15 limit the horizontal state of the limiting rod 12, misalignment can be avoided when the left cabinet 1 and the right cabinet 9 are separated.
[0027] Example 2: Slide rails 2 are respectively installed between the upper and lower parts of the inner walls of the left cabinet 1 and the right cabinet 9, and slide sleeves 3 are movably inserted into the slide rails 2. The slide sleeves 3 have grooves 23 arranged longitudinally inside. Bolts 4 are installed in the screw holes at the front and rear ends of the slide sleeves 3. Two sets of partitions 5 are respectively installed inside the left cabinet 1 and the right cabinet 9. Storage chambers 8 are arranged horizontally inside the partitions 5, and telescopic plates 7 are movably inserted between the storage chambers 8. The side of the storage chambers 8 has slots 24.
[0028] The telescopic plate 7 is embedded in the storage chamber 8 on both sides. The telescopic plate 7 can slide left and right along the inner wall of the partition 5. The sliding sleeve 3 is sleeved on the outside of the slide rail 2 with the slot 23. The sliding sleeve 3 can rise and fall vertically along the outer wall of the slide rail 2.
[0029] Specifically, such as Figure 1 and Figure 3 As shown, the partition 5 inside the left cabinet 1 and the right cabinet 9 is also connected by the telescopic plate 7 in the storage chamber 8. It can be pulled out automatically as the distance between the left cabinet 1 and the right cabinet 9 changes, until the partition 5 and the storage chamber 8 form a complete support structure. It can also move up and down along the slide rails 2 on both sides, and use the bolts 4 in the screw holes to lock and fix it.
[0030] Example 3: Door panels 25 are hinged to the front sides of the left cabinet 1 and the right cabinet 9 respectively. A longitudinal groove 16 is provided between the upper and lower parts of the front center of the door panel 25. A movable block 22 is inserted into the longitudinal groove 16. A stop block 26 is welded horizontally to the front of the movable block 22. A hanging ring 20 is welded to the bottom center of the stop block 26. A bracket 18 is fixed between the upper and lower parts of the two sides of the front of the door panel 25 respectively. A rotating block 19 is movably connected between the upper and lower parts of the bracket 18. A fitting piece 21 is fixed to the top of the rotating block 19. The movable block 22 can slide vertically along the longitudinal groove 16. The rotating block 19 can fit against the two sides of the bottom of the stop block 26.
[0031] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the left cabinet 1, the right cabinet 9, and the folding sleeve 6 connected at the center can all be opened from the front door panel 25. The movable block 22 and the stop block 26 installed at its front end can be moved vertically along the longitudinal groove 16. According to the length of the object to be hung, the appropriate height of the bracket 18 can be selected and the hinged rotating block 19 can be rotated so that the fitting piece 21 of the rotating block 19 abuts against the stop block 26 for support.
[0032] Working principle: In use, the left cabinet 1 and the right cabinet 9 are connected by a central folding sleeve 6. Rotating the screw 11 installed between the bottom threaded blocks 13, the left cabinet 1 and the right cabinet 9, equipped with threaded blocks 13, are pushed laterally between the fixing sleeves 17 on both sides. Because the first hole 14 and the second hole 15 limit the horizontal position of the limiting rod 12, misalignment when the left cabinet 1 and the right cabinet 9 separate is prevented. The partition 5 inside the left cabinet 1 and the right cabinet 9 is also connected by a telescopic plate 7 in the storage chamber 8, allowing it to automatically pull out as the distance between the left cabinet 1 and the right cabinet 9 changes, until the partition 5 is in contact with the storage chamber. The chamber 8 forms a complete support structure, and the sliding sleeve 3 with the slot 23 can be moved up and down along the slide rails 2 on both sides, and locked and fixed with the bolts 4 in the screw holes, thereby adjusting the vertical placement distance. The left cabinet 1, the right cabinet 9 and the folding sleeve 6 connected in the center can all be opened from the front door panel 25. The movable block 22 and the stop block 26 installed at its front end can be moved vertically along the longitudinal groove 16. According to the length of the object to be hung, the appropriate height bracket 18 can be selected and the hinged rotating block 19 can be rotated so that the fitting piece 21 of the rotating block 19 abuts against the stop block 26 for support, making it convenient for the bottom hanging ring 20 to hang different objects.
