Description

Technical Field

[0001] This utility model relates to the field of stool technology, and in particular to a multifunctional high and low stool. Background Technology

[0002] A high and low stool is a stool with different height levels. It is usually composed of two stools of different heights, one high and one low. It can be used not only as a regular seat, but also as an auxiliary platform for a desk or computer desk, or as a small work platform or storage platform.

[0003] The high stool is often used to elevate oneself when climbing, so as to carry out construction work at a relatively high position. However, the height of the high stool is fixed, which makes it difficult for the fixed-height high stool to meet the needs of work at different heights, thus reducing the practicality of the high stool. Utility Model Content

[0004] This utility model proposes a multi-functional high and low stool to address the problem that the fixed height of high stools makes it difficult to meet the work needs of different heights, thus reducing the practicality of high and low stools.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a multifunctional high and low stool, including a storage box, with a drawer slidably connected to the inner wall of the storage box. A first stool board and a second stool board are respectively provided on the top and one side of the storage box. An adjustment device is provided between the first stool board and the storage box. The adjustment device includes four rectangular rods, one end of each of the four rectangular rods being fixedly connected to the four corners of the bottom of the first stool board. Sleeves are slidably connected to the outer surfaces of the rectangular rods, and one end of each of the four sleeves is fixedly connected to the four corners of the top of the storage box. First extension blocks are symmetrically fixedly connected to both sides of the first stool board. Threaded rods are fixedly connected to the bottom of the first extension blocks. Threaded cylinders are threadedly connected to the outer surfaces of the threaded rods. Second extension blocks are provided on the outer surfaces of the threaded cylinders. One side of each of the two second extension blocks is symmetrically fixedly connected to both sides of the storage box. A support frame is fixedly connected to the bottom of the second stool board, and one side of the support frame is fixedly connected to one side of the storage box. An auxiliary device is provided on the top of the first and second stool boards.

[0006] The effect achieved by the above components is as follows: by setting up a threaded rod and a threaded cylinder, rotating the threaded cylinder will cause the threaded rod to extend and retract on the inner wall of the threaded cylinder. During the extension and retraction of the threaded rod, it will cause the first stool connected to the first extension block to move in the vertical direction. The first stool will cause the rectangular rod to slide synchronously on the inner wall of the sleeve, thereby facilitating the adjustment of the height of the first stool, i.e., the high stool, according to actual needs, which can meet the working needs of different heights, and thus improve the practicality of the high stool.

[0007] Preferably, a bearing is fixedly connected to the outer surface of the threaded cylinder, and the outer surface of the bearing is fixedly connected to the inner wall of the second extension block.

[0008] The effect achieved by the above components is that by setting bearings, the friction between the threaded cylinder and the second extension block can be reduced when rotating the threaded cylinder, making it easier to rotate the threaded cylinder.

[0009] Preferably, an operating block is fixedly connected to one end of the threaded cylinder, and the outer surface of the operating block is provided with protrusions.

[0010] The effect achieved by the above components is as follows: by setting the operating block, rotating the operating block can drive the threaded cylinder to rotate. At the same time, the outer surface of the operating block is provided with protrusions, which can effectively increase the friction of the outer surface of the operating block and have an anti-slip effect when rotating the operating block.

[0011] Preferably, a bolt is provided on one side of the sleeve, and the bolt is threaded into the inner wall of the sleeve.

[0012] The effect achieved by the above components is as follows: by setting the bolt and rotating the bolt, the bolt can be extended and retracted on the inner wall of the sleeve until one end of the bolt abuts against one side of the rectangular rod, thus fixing the rectangular rod and the sleeve. This reduces the supporting pressure of the threaded rod and threaded sleeve on the first bench plate, making the structure of the high bench section more stable.

[0013] Preferably, an auxiliary groove is provided on one side of the rectangular rod, and a rubber strip is fixedly connected to the inner wall of the auxiliary groove.

[0014] The effect achieved by the above components is that by setting the rubber strip, one side of the rectangular rod can be replaced to abut against one end of the threaded pin, and the friction between the threaded pin and the rectangular rod can be increased, making the fixation of the threaded pin between the rectangular rod and the sleeve more stable.

[0015] Preferably, the auxiliary device includes two rubber plates, the top of which is uniformly provided with grooves. The two rubber plates are respectively disposed on the top of the first bench and the second bench. The bottom of the rubber plates is fixedly connected with inserts, and the outer surfaces of the two inserts are respectively inserted into the inner walls of the first bench and the second bench.

[0016] The effect achieved by the above-mentioned components is as follows: By setting the rubber plate with grooves, the rubber plate is mainly composed of high-strength board material and a grooved rubber layer on the board bench. This structure is mainly to ensure that the rubber plate has a high load-bearing capacity. The inserts at the bottom of the two rubber plates are respectively inserted into the inner walls of the first bench and the second bench, which can fix the rubber plate and the first bench and the second bench respectively. The rubber plate with grooves can increase the friction at the top of the first bench and the second bench, so that the workers can step on the top of the first bench and the second bench with an anti-slip effect. At the same time, the rubber plate is detachable, which makes it easy to remove and replace the rubber plate that is worn out.

[0017] Preferably, the bottom of the first and second stools are symmetrically rotatably connected with slot blocks, and the bottom of the insert blocks are symmetrically fixedly connected with threaded pins. The outer surface of the threaded pins is inserted into the inner wall of the slot blocks, and the outer surface of the threaded pins is threaded with nuts.

[0018] The effect achieved by the above-mentioned components is as follows: by setting the slot block, rotating the slot block allows the threaded pin to enter the inner wall of the slot block, and then rotating the nut allows one side of the nut to abut against one side of the slot block, thus fixing the insert block and the first or second stool plate, which helps to prevent the rubber plate from easily detaching from the first and second stool plates.

[0019] Preferably, a rubber pad is fixedly connected to one side of the nut, the outer surface of the threaded pin is inserted into the inner wall of the rubber pad, and a round block is fixedly connected to one end of the threaded pin.

[0020] The effects achieved by the above components are as follows: by setting a rubber pad, one side of the nut can abut against one side of the slot block, which helps to prevent the nut from loosening. At the same time, by setting a round block, one end of the threaded pin can be limited, which helps to prevent the nut from falling off the threaded pin due to misoperation.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting a threaded rod, the threaded rod can drive the first stool to move in the vertical direction, thereby facilitating the adjustment of the height of the first stool, i.e. the high stool, according to actual needs, which can meet the working requirements of different heights, and thus improve the practicality of the high stool.

[0029] Example 1, referring to Figures 1-3As shown, this embodiment discloses a multifunctional high and low stool, including a storage box 1. A drawer 2 is slidably connected to the inner wall of the storage box 1. A first stool board 3 and a second stool board 4 are respectively provided on the top and one side of the storage box 1. An adjustment device 5 is provided between the first stool board 3 and the storage box 1. The adjustment device 5 includes four rectangular rods 51, one end of each of the four rectangular rods 51 being fixedly connected to the four corners of the bottom of the first stool board 3. Sleeves 52 are slidably connected to the outer surface of the rectangular rods 51, one end of each of the four sleeves 52 being fixedly connected to the four corners of the top of the storage box 1. First extension blocks 53 are symmetrically fixedly connected to both sides of the first stool board 3. A threaded rod 54 is fixedly connected to the bottom of the first extension block 53. A threaded cylinder 55 is threadedly connected to the outer surface of the threaded rod 54. A second extension block 56 is provided on the outer surface of the threaded cylinder 55. One side of each of the two second extension blocks 56 is connected to the storage box 1. The two sides of the storage box 1 are symmetrically fixedly connected. The bottom of the second stool 4 is fixedly connected to a support frame 6. One side of the support frame 6 is fixedly connected to one side of the storage box 1. The top of the first stool 3 and the second stool 4 are provided with an auxiliary device 7. By setting a threaded rod 54 and a threaded cylinder 55, rotating the threaded cylinder 55 will cause the threaded rod 54 to extend and retract on the inner wall of the threaded cylinder 55. During the extension and retraction, the threaded rod 54 will cause the first stool 3 connected to the first extension block 53 to move vertically. The first stool 3 will cause the rectangular rod 51 to slide synchronously on the inner wall of the sleeve 52, so that the height of the first stool 3, i.e., the high stool, can be adjusted according to actual needs to meet the working needs of different heights, thereby improving the practicality of the high stool. By setting the storage box 1 and the drawer 2, the high stool can have a storage function.

[0030] Reference Figure 2 and Figure 3 As shown, a bearing 57 is fixedly connected to the outer surface of the threaded cylinder 55. The outer surface of the bearing 57 is fixedly connected to the inner wall of the second extension block 56. By setting the bearing 57, the friction between the threaded cylinder 55 and the second extension block 56 can be reduced when rotating the threaded cylinder 55, making it easier to rotate the threaded cylinder 55. An operating block 58 is fixedly connected to one end of the threaded cylinder 55. The outer surface of the operating block 58 is provided with protrusions. By setting the operating block 58, rotating the operating block 58 can drive the threaded cylinder 55 to rotate. At the same time, the protrusions on the outer surface of the operating block 58 can effectively increase the friction of the outer surface of the operating block 58, which has an anti-slip effect when rotating the operating block 58.

[0031] Reference Figure 2 and Figure 3As shown, a bolt 59 is provided on one side of the sleeve 52. The bolt 59 is threaded into the inner wall of the sleeve 52. By providing the bolt 59 and rotating the bolt 59, the bolt 59 can extend and retract within the inner wall of the sleeve 52 until one end of the bolt 59 abuts against one side of the rectangular rod 51. This can fix the rectangular rod 51 and the sleeve 52, reducing the supporting pressure of the threaded rod 54 and the threaded sleeve 55 on the first stool 3, making the structure of the stool part more stable. An auxiliary groove 510 is provided on one side of the rectangular rod 51. A rubber strip 511 is fixedly connected to the inner wall of the auxiliary groove 510. By providing the rubber strip 511, it can replace one side of the rectangular rod 51 in abutting against one end of the threaded pin 74, and increase the friction between the threaded pin 74 and the rectangular rod 51, making the fixation of the threaded pin 74 between the rectangular rod 51 and the sleeve 52 more stable.

[0032] Reference Figures 3-5 As shown, the auxiliary device 7 includes two rubber plates 71. The top of each rubber plate 71 has evenly spaced grooves. The two rubber plates 71 are respectively positioned on the top of the first bench 3 and the second bench 4. The bottom of each rubber plate 71 is fixedly connected to an insert 72. The outer surfaces of the two inserts 72 are respectively inserted into the inner walls of the first bench 3 and the second bench 4. By setting the rubber plates 71 with grooves, the rubber plates 71 are mainly composed of high-strength sheet material and a rubber layer with grooves on the sheet material bench. This structure is mainly to ensure that the rubber plates 71 have a high load-bearing capacity. By inserting the inserts 72 at the bottom of the two rubber plates 71 into the inner walls of the first bench 3 and the second bench 4, the rubber plates 71 and the first bench 3 and the second bench 4 can be fixed respectively. The rubber plates 71 with grooves can increase the friction on the top of the first bench 3 and the second bench 4, so that the workers can step on the top of the first bench 3 and the second bench 4 with an anti-slip effect. At the same time, the rubber plates 71 are detachable, which makes it easy to remove and replace the rubber plates 71 that are worn out.

[0033] Reference Figure 4 and Figure 5As shown, the bottom of the first bench 3 and the second bench 4 are symmetrically rotatably connected with slot blocks 73, and the bottom of the insert block 72 is symmetrically fixed with threaded pins 74. The outer surface of the threaded pin 74 is inserted into the inner wall of the slot block 73, and a nut 75 is threadedly connected to the outer surface of the threaded pin 74. By setting the slot block 73, rotating the slot block 73 causes the threaded pin 74 to enter the inner wall of the slot block 73. Then, rotating the nut 75 causes one side of the nut 75 to abut against one side of the slot block 73, thus securing the insert block 72 to the first bench 3 or the second bench 4. The rubber pad 71 is fixed to prevent it from easily detaching from the first bench plate 3 and the second bench plate 4. A rubber pad 76 is fixedly connected to one side of the nut 75, and the outer surface of the threaded pin 74 is inserted into the inner wall of the rubber pad 76. A round block 77 is fixedly connected to one end of the threaded pin 74. By setting the rubber pad 76, one side of the nut 75 can be replaced to abut against one side of the slot block 73, which helps to prevent the nut 75 from loosening. At the same time, by setting the round block 77, one end of the threaded pin 74 can be limited, which helps to prevent the nut 75 from detaching from the threaded pin 74 due to misoperation.

[0034] Working principle: Rotating the operating block 58 drives the threaded cylinder 55 to rotate. The threaded cylinder 55 drives the threaded rod 54 to extend and retract within the inner wall of the threaded cylinder 55. During the extension and retraction of the threaded rod 54, it drives the first seat plate 3 connected to the first extension block 53 to move vertically. The first seat plate 3 drives the rectangular rod 51 to slide synchronously within the inner wall of the sleeve 52 until the first seat plate 3 reaches a suitable height. Then, rotating the bolt 59 causes it to extend and retract within the inner wall of the sleeve 52 until one end of the bolt 59 abuts against the rubber strip 511 on one side of the rectangular rod 51. This fixes the rectangular rod 51 and the sleeve 52, reducing the impact of the threaded rod 54 and the threaded cylinder 55 on the first seat plate 52. The supporting pressure of plate 3 makes the structure of the stool more stable. When it is necessary to install the rubber plate 71, insert the bottom of the two rubber plates 71 into the inner wall of the first stool plate 3 and the second stool plate 4 respectively, then rotate the slot block 73 so that the threaded pin 74 enters the inner wall of the slot block 73, and then rotate the nut 75 so that the rubber pad 76 on one side of the nut 75 abuts against one side of the slot block 73. This can fix the rubber plate 71 to the first stool plate 3 and the second stool plate 4 respectively. The rubber plate 71 with grooves can increase the friction on the top of the first stool plate 3 and the second stool plate 4, so that the workers can step on the top of the first stool plate 3 and the second stool plate 4 without slipping.
