[0027] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The foldable storage rack involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0028] Reference Figures 1 to 9 This utility model provides a foldable storage rack, including a pin telescopic mechanism 1, and further including: an inner pull rod 2, a middle pull rod 3, an outer pull rod 4, and a storage basket 5. The pin telescopic mechanism 1 is disposed inside the inner pull rod 2. The side of the inner pull rod 2 is movably connected to the inside of the middle pull rod 3, and the side of the middle pull rod 3 is movably connected to the inside of the outer pull rod 4. The sides of the inner pull rod 2, the middle pull rod 3, and the outer pull rod 4 are respectively fixedly connected to the sides of the storage basket 5. The top of the inner pull rod 2 is movably connected to the side of a button 101. A bent rod 102 is fixedly connected to the bottom end of key 101. A spring 103 is fixedly connected to the bottom end of bent rod 102. Long rods 104 are fixedly connected to both ends of the bottom surface of bent rod 102. A support leg 105 is fixedly connected to the bottom end of long rod 104. A pin telescopic assembly 106 is provided at the bottom end of support leg 105. Pressing key 101 causes bent rod 102 to drive long rod 104 to press down, causing the cylindrical pin 1063 of pin telescopic assembly 106 to retract. At this time, pulling up inner layer pull rod 2 can freely change the relative position between inner layer pull rod 2 and middle layer pull rod 3.
[0029] The pin telescopic assembly 106 includes a limiting frame 1061. A slider 1062 is movably connected to the bottom end of the limiting frame 1061. A cylindrical pin 1063 and a spring 1064 are fixedly connected to the side of the slider 1062. The slider 1062 is located inside the fixed shell 1065. The inner wall of the fixed shell 1065 is fixedly connected to one end of the spring 1064. A bottom pad 1066 is fixedly connected to the bottom end of the fixed shell 1065. The top end of the bottom pad 1066 is fixedly connected to the bottom end of the inner pull rod 2. When the limiting frame 1061 is pressed down by the long rod 104, its bottom end will slide down along the limiting groove on the side of the slider 1062. When the slider 1062 is retracted into the fixed shell 1065 by the force of the long rod 104, the cylindrical pin 1063 will also retract. At this time, the inner pull rod 2 can slide up and down within the middle pull rod 3.
[0030] The inner tie rod 2 has a circular through hole at the bottom side that corresponds to the position of the cylindrical pin 1063, which facilitates the popping out or retracting of the cylindrical pin 1063.
[0031] The inner bottom of the middle layer pull rod 3 is provided with a limit pin 301. The bottom end of the limit pin 301 is movably connected to a sliding block 302. The side of the sliding block 302 is fixedly connected with a cylindrical pin 303 and a spring 304. The inside of the spring 304 is provided with a square pin 305. One end of the square pin 305 is fixedly connected to a spring 406. One end of the spring 406 is fixedly connected to the inside of the sliding block 302. The bottom side of the middle layer pull rod 3 is provided with a circular through hole corresponding to the cylindrical pin 303 and a square through hole corresponding to the square pin 305. When the inner layer pull rod 2 is pressed against the bottom of the middle layer pull rod 3, the cylindrical pin 303 is in a retracted state and the square pin 305 is in an extended state. When the mechanism at the bottom of the middle layer pull rod 3 loses pressure, the square pin 305 will retract inward under the action of the spring 406.
[0032] The middle layer tie rod 3 has evenly distributed circular through holes on its side in the vertical direction. When the cylindrical pin 1063 passes through one of the through holes, it pops out and locks the relative position of the inner layer tie rod 2 and the middle layer tie rod 3.
[0033] The outer pull rod 4 is hollow inside and has evenly distributed through holes on its side. The bottom side of the outer pull rod 4 has a square through hole corresponding to the position of the square pin 305. The square pin 305 in the extended state will lock the relative position of the middle pull rod 3 and the outer pull rod 4.
[0034] Among them, the bottom end of the outer pull rod 4 is fixedly connected to a roller 401, and the side of the roller 401 is movably connected to a locking member 402. The user can easily click the shelf through the roller 401.
[0035] Among them, the upper side of the inner pull rod 2 is fixedly connected to a fixing ring 501, and the side of the fixing ring 501 is fixedly connected to a basket 502. The basket 502 is in the shape of an inverted trapezoid, and the edges of the sides and bottom are rounded. The inverted trapezoid shape allows the upper and lower storage baskets 5 to be stacked, which helps to reduce the folding space.
[0036] The working principle of this utility model is as follows: This utility model provides a foldable storage rack, including a pin telescopic mechanism 1, an inner pull rod 2, a middle pull rod 3, an outer pull rod 4, and a storage basket 5. The pin telescopic mechanism 1 is located inside the inner pull rod 2. The side of the inner pull rod 2 is movably connected to the inside of the middle pull rod 3, and the side of the middle pull rod 3 is movably connected to the inside of the outer pull rod 4. The sides of the inner pull rod 2, the middle pull rod 3, and the outer pull rod 4 are respectively fixedly connected to the sides of the storage basket 5. The top of the inner pull rod 2 is movably connected to the side of a button 101. A bent rod 102 is fixedly connected to the bottom of the button 101, and a spring 103 is fixedly connected to the bottom of the bent rod 102. Long rods 104 are fixedly connected to both ends of the bottom surface of the bent rod 102. A support leg 105 is fixedly connected to the end of the support leg 105. A pin telescopic assembly 106 is provided at the bottom end of the support leg 105. Pressing the button 101 causes the bent rod 102 to drive the long rod 104 downward. The pin telescopic assembly 106 includes a limit frame 1061. A slider 1062 is movably connected to the bottom end of the limit frame 1061. A cylindrical pin 1063 and a spring 1064 are fixedly connected to the side of the slider 1062. The slider 1062 is located inside the fixed shell 1065. The inner wall of the fixed shell 1065 is fixedly connected to one end of the spring 1064. A bottom pad 1066 is fixedly connected to the bottom end of the fixed shell 1065. The top end of the bottom pad 1066 is fixedly connected to the bottom end of the inner pull rod 2. When the limit frame 1061 is pressed down by the long rod 104, the bottom end will move along the side of the slider 1062. As the limiting groove slides down, the slider 1062 retracts into the fixed shell 1065 under the force of the long rod 104, and the cylindrical pin 1063 retracts accordingly. At this time, the inner pull rod 2 can slide up and down within the middle pull rod 3. Pulling up the inner pull rod 2 can freely change the relative position between the inner pull rod 2 and the middle pull rod 3. Releasing the button 101 will cause the bent rod 102 to spring back to its original position due to the force of the spring 103, and the long rod 104 will move upward. The pin telescopic assembly 106 loses the force from above, and the cylindrical pin 1063 will pop out again due to the force of the spring 1064. The side of the middle pull rod 3 has evenly distributed circular through holes in the vertical direction. When the cylindrical pin 1063 pops out after passing through one of the through holes, the relative position between the inner pull rod 2 and the middle pull rod 3 can be locked. The user can... The relative distance between the inner pull rod 2 and the middle pull rod 3 can be adjusted as needed. A limit pin 301 is provided at the bottom of the middle pull rod 3. A sliding block 302 is movably connected to the bottom of the limit pin 301. A cylindrical pin 303 and a spring 304 are fixedly connected to the side of the sliding block 302. A square pin 305 is provided inside the spring 304. A spring 306 is fixedly connected to one end of the square pin 305. One end of the spring 306 is fixedly connected to the inside of the sliding block 302. The bottom side of the middle pull rod 3 has a circular through hole corresponding to the cylindrical pin 303 and a square through hole corresponding to the square pin 305. When the inner pull rod 2 is pressed against the bottom of the middle pull rod 3, the cylindrical pin 303 is retracted, and the square pin 305 is extended.The outer pull rod 4 has a square through hole at its bottom side corresponding to the position of the square pin 305. When the square pin 305 is extended, it locks the relative position of the middle pull rod 3 and the outer pull rod 4. When the inner pull rod 2 is pulled up, the mechanism at the bottom of the middle pull rod 3 loses pressure. Under the action of the spring 306, the square pin 305 retracts inward, releasing the locking state between the middle pull rod 3 and the outer pull rod 4. When the inner pull rod 2 is locked in any through hole on the side of the middle pull rod 3 (excluding the bottom), the upward movement of the inner pull rod 2 will drive the middle pull rod 3 to move upward. The outer pull rod 4 is hollow inside, with evenly distributed through holes on its sides. When in the pre-expanded state... When the cylindrical pin 303 passes through the evenly distributed through holes on the side of the outer pull rod 4, it pops out, locking the relative position of the middle pull rod 3 and the outer pull rod 4. In summary, by pressing button 101, the position of the three pull rods can be easily adjusted to achieve the desired height and meet different storage needs. When the shelf is not needed, pressing button 101 while pressing down on the pull rods will compress the length of the three pull rods to its shortest length. The storage baskets 5 on the sides of the three pull rods are inverted trapezoidal in shape, with rounded corners on the sides and bottom. The inverted trapezoidal shape allows the upper and lower storage baskets 5 to be stacked, minimizing the space required after folding.
[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
