Description

Technical Field

[0002] In the prior art, wrought iron storage racks usually use fasteners such as screws and nuts to fix multiple shelves and multiple support rods together to form a stable storage structure.

Even if there are multiple holes for installing shelves on the support rods in existing storage racks, when adjusting the height of the shelves, the shelves and their fixing components need to be removed and adjusted and then re-fixed and installed. The operation is relatively cumbersome and lacks flexibility and convenience. Utility Model Content

DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0025] See also Figures 1-9 , this embodiment is a plug-in assembly structure of an iron storage shelf panel, including a support rod 1 and a layer plate 2. The horizontal cross-section of the layer plate 2 is rectangular. The support rod 1 is provided with four positions close to the four corners of the layer plate 2. A vertical linear track 11 is provided in the support rod 1. A plurality of locking mechanisms 3 are provided in the linear track 11. The locking mechanisms 3 slide up and down and can be locked in the linear track 11. The four corners of the layer plate 2 are respectively plugged and connected with the four locking mechanisms 3 at the same height in the four support rods 1.

[0026] The utility model places four support rods 1 vertically, and the positions of the four support rods 1 correspond to the positions of the four corners of the layer board 2, and the layer board 2 is inserted and fixed in four locking mechanisms 3 of the same height in the four support rods 1. By applying a vertical force to the layer board 2, the locking mechanism 3 slides in the linear track 11, thereby moving the layer board 2 to a desired height, and then locking the locking mechanism 3 in the linear track 11 to fix the height of the layer board 2, and sequentially inserting multiple layer boards 2 into the locking mechanisms 3 of different heights in the above manner, thereby completing the assembly of the utility model.

[0027] Since the middle board 2 of the present invention is connected to the support rod 1 by being plugged into the locking mechanism 3, no additional professional tools are required during assembly of the present invention, thereby reducing the difficulty of assembly and shortening the time required for assembly. At the same time, since the locking mechanism 3 can slide vertically and lock in the linear track 11 in the support rod 1, the height of each layer board 2 can be conveniently adjusted and then locked through the action of the locking mechanism 3 during assembly and use. The operation is relatively simple and has good flexibility and convenience. After adjustment, each layer board 2 can be used to accommodate items of different heights, thereby improving the space utilization rate of the storage rack.

[0028] See also Figure 4The locking mechanism 3 includes a bottom plate 31, a left roller 32, an upper roller 33 and a lower roller 34. The left roller 32 is rotatably arranged on the bottom plate 31, and the left roller 32 is fixedly connected to the layer plate 2. The left roller 32 is against the left side surface of the linear track 11, and the upper roller 33 and the lower roller 34 are against the right side surface of the linear track 11. A trigger mechanism 4 is provided on the bottom plate 31, and the left roller 32 drives the upper roller 33 and the lower roller 34 to contact and separate with the right side surface of the linear track 11 through the trigger mechanism 4. The upper roller 33 is connected to the trigger mechanism 4 in a counterclockwise unidirectional rotation, and the lower roller 34 is connected to the trigger mechanism 4 in a clockwise unidirectional rotation. A locking member 5 is provided between the bottom plate 31 and the support rod 1 for fixing the locking mechanism 3 in the support rod 1.

[0029] When the height of the shelf 2 needs to be adjusted, the locking piece 5 is first unlocked. At this time, the shelf 2 and the locking mechanism 3 tend to move downward under the action of their own gravity. Since the lower roller 34 can only rotate in one direction clockwise, the static friction between the lower roller 34 and the linear track 11 can provide a supporting force for the locking mechanism 3 and the shelf 2, thereby preventing the shelf 2 from moving downward; when an additional downward force is applied to the shelf 2, the left roller 32 fixedly connected to the shelf 2 separates the lower roller 34 from the linear track 11 through the trigger mechanism 4, and the upper roller 33 can rotate counterclockwise, so that the shelf 2 and the locking mechanism 3 can move downward; when the force applied to the shelf 2 is removed, the lower roller 34 resets and contacts the linear track 11 to generate friction resistance, thereby preventing the shelf 2 from continuing to move downward.

[0030] Similarly, when an additional upward force is applied to the layer plate 2, the left roller 32 fixedly connected to the layer plate 2 separates the upper roller 33 from the linear track 11 through the trigger mechanism 4, and the lower roller 34 can rotate clockwise, so that the layer plate 2 and the locking mechanism 3 can move upward; when the force applied to the layer plate 2 is removed, the upper roller 33 returns to contact with the linear track 11. Since the upper roller 33 can only rotate in one direction counterclockwise, friction resistance is generated between the upper roller 33 and the linear track 11, so that the layer plate 2 can quickly decelerate and stop, and remain motionless under the action of the friction resistance between the lower roller 34 and the linear track 11.

[0031] When the shelf 2 is adjusted to the desired height, the locking member 5 is reactivated to secure the bottom plate 31 within the support rod 1, thereby enabling the shelf 2 to be used to carry heavy objects, ensuring the normal operation of the utility model. This adjustment operation only requires adjusting the locking member 5 and pushing the shelf 2 up and down, without having to remove the shelf 2 from the support rod 1, which is highly convenient to operate.

[0032] See also Figure 4-Figure 6A vertical sliding hole 35 is opened on the bottom plate 31, and the left roller 32 slides up and down along the sliding hole 35 and can rotate. The trigger mechanism 4 includes two upper rotating parts 41 and a lower rotating part 42 which are symmetrically arranged with respect to the left roller 32. The upper rotating part 41 and the lower rotating part 42 are both rotatably arranged on the bottom plate 31. The inner ends of the upper rotating part 41 and the lower rotating part 42 are both against the left roller 32. The upper roller 33 is arranged on the outer end of the upper rotating part 41 for counterclockwise rotation, and the lower roller 34 is arranged on the outer end of the lower rotating part 42 for clockwise rotation. The upper rotating part 41 and the lower rotating part 42 are both provided with a torsion spring 43 that drives the upper roller 33 and the lower roller 34 to press against the linear track 11.

[0033] When it is necessary to drive the layer plate 2 to move downward, a downward force is applied to the layer plate 2. Since the layer plate 2 is fixedly connected to the left roller 32, the left roller 32 is subjected to a downward force. The left roller 32 moves downward along the slide hole 35 and drives the lower rotating member 42 to rotate clockwise so that the lower roller 34 is separated from the linear track 11, and the upper roller 33 remains in contact with the linear track 11. According to the above analysis of the working principle of the trigger mechanism 4, it can be seen that the layer plate 2 can move downward at this time, and after the applied force is removed, the lower rotating member 42 is reset under the action of the torsion spring 43 so that the lower roller 34 is against the linear track 11, so that the layer plate 2 can automatically stop moving.

[0034] Similarly, when it is necessary to drive the layer plate 2 to move upward, by applying an upward force to the layer plate 2, the left roller 32 drives the upper rotating member 41 to rotate counterclockwise so that the upper roller 33 is separated from the linear track 11, and the lower roller 34 remains in contact with the linear track 11. According to the above analysis of the working principle of the trigger mechanism 4, the layer plate 2 can move upward at this time, and after the applied force is removed, the upper rotating member 41 is reset under the action of the torsion spring 43 so that the upper roller 33 is against the linear track 11, so that the layer plate 2 can quickly decelerate and stop, and remain motionless under the action of the friction resistance between the lower roller 34 and the linear track 11.

[0035] See also Figure 4 、 Figure 7 The locking member 5 includes a plug post 51 and a pull ring 52. The pull ring 52 is arranged at the outer end of the plug post 51. A strip hole 12 for the plug post 51 to slide up and down is opened in a vertical direction on the support plate. The plug post 51 is inserted into the strip hole 12 and the bottom plate 31 and the plug post 51 is against the lower side of the lower rotating member 42. The inner end of the plug post 51 is provided with a groove 13 for inserting the lower rotating member 42. The inner end of the plug post 51 is provided with a limit block 54 with a diameter larger than the plug post 51. A steel ball 55 is slidingly provided in the middle position of the plug post 51. The steel ball 55 is pressed against the groove 13 in the support rod 1 by a spring 56.

[0036] When the pin 51 is inserted inward, the position of the groove 13 and the lower rotating part 42 are offset, and the pin 51 prevents the lower rotating part 42 from rotating clockwise. At this time, when an object is placed on the shelf 2 and a downward force is applied to the shelf 2, the lower roller 34 still remains against the linear track 11, thereby increasing the shelf 2's ability to bear the weight of the object, and the action of the steel ball 55 and the groove 13 reduces the looseness between the pin 51 and the support rod 1, causing the insertion rod 21 to move outward.

[0037] When the plug post 51 is pulled out, the steel ball 55 moves into the plug post 51, moves the position of the groove 13 to the bottom of the lower rotating part 42, and prevents the plug post 51 from being pulled out further through the limit block 54, so that the lower rotating part 42 can rotate clockwise and be inserted into the groove 13. At this time, by applying a downward force to the layer plate 2, the lower roller 34 can be separated from the linear track 11, thereby moving the layer plate 2 downward. When the layer plate 2 moves up and down, the outer end of the plug post 51 moves in the strip hole 12 on the support rod 1, so that the plug post 51 and the pull ring 52 are always exposed on the support rod 1, thereby facilitating the insertion and removal of the plug post 51 through the pull ring 52.

[0038] See also Figure 8 A ratchet mechanism 6 is provided between the upper rotating member 41 and the upper roller 33 to limit the counterclockwise unidirectional rotation of the upper roller 33, and another ratchet mechanism 6 is provided between the lower rotating member 42 and the lower roller 34 to limit the clockwise unidirectional rotation of the lower roller 34.

[0039] The ratchet mechanism 6 has the characteristic of being able to rotate only in one direction and being locked in reverse rotation, and has a relatively stable structure, which can better achieve the purpose of one-way rotation between the upper roller 33 and the upper rotating member 41, and between the lower roller 34 and the lower rotating member 42. The two ratchet mechanisms 6 can adopt ratchet mechanisms 6 with the same specifications and parameters. When installing, the two ratchet mechanisms 6 are installed in opposite directions, so that the upper roller 33 and the lower roller 34 can be rotated in opposite directions.

[0040] See also Figure 8 The ratchet mechanism 6 includes an inner gear ring 61 and a pawl ring 62. The pawl ring 62 is provided with a plurality of pawls 63 at equal intervals around the circumference. The pawls 63 are engaged with the inner gear ring 61. The upper roller 33 and the lower roller 34 are respectively fixedly connected to the inner gear rings 61 of the two ratchet mechanisms 6. The upper rotating member 41 and the lower rotating member 42 are respectively fixedly connected to the pawl rings 62 of the two ratchet mechanisms 6.

[0041] By having multiple pawls 63 distributed at equal intervals around the circumference engage with the inner gear ring 61 at the same time, the stability of the engagement between the pawl ring 62 and the inner gear ring 61 is improved, thereby reducing the possibility of the pawl 63 detaching from the inner gear ring 61 and causing the upper roller 33 and the lower roller 34 to rotate in the opposite direction in their specified directions, thereby reducing the failure rate when using the utility model.

[0042] See also Figure 9 A plug-in board 36 is fixed to the outside of the left roller 32. A slot 37 with a T-shaped cross-section and an insertion rod 21 are respectively provided on the plug-in board 36 and the left and right sides of the layer plate 2. The insertion rod 21 is slidably inserted into the slot 37.

[0043] The installation of the layer board 2 is achieved by simultaneously inserting the insertion rod 21 on the left side of the layer board 2 into the slots 37 of the two plug-in boards 36 on the left side, and simultaneously inserting the insertion rod 21 on the right side of the layer board 2 into the slots 37 of the two plug-in boards 36 on the right side. When the layer board 2 is disassembled, the layer board 2 is pushed forward or backward so that the insertion rod 21 slides out of the slot 37, thereby achieving the removal of the layer board 2, which has the advantage of simple operation.
