Description

Technical Field

[0001] This utility model relates to the field of height-adjustable desks, specifically a height-adjustable desk that is easy to adjust. Background Technology

[0002] Adjustable desks are widely used in people's daily lives, such as in schools, offices, and hospitals, mainly for storing items and assisting in office work. As people's living standards continue to improve, their functional needs for desks are also increasing.

[0003] A patent with publication number CN213344714U discloses an adjustable height-adjustable table, including a tabletop. A column is fixedly connected to the bottom surface of the tabletop, and a column is slidably connected to the column. The column and column form a support leg. The same lifting device is installed in each support leg. The lifting device includes a rotating shaft. The bottom end of the rotating shaft is rotatably connected to the inner surface of the column. The lower half of the rotating shaft has a clockwise thread. An adjustment device is installed between the two support legs. By rotating the rotating shaft on the left, the threaded teeth on the left end of the rotating shaft move forward, causing the rotating shaft to rotate. The rotating shaft causes the ring to move upward on the rotating shaft, which in turn causes the column to slide upward in the column and move the tabletop upward, thus raising the left support leg. The right support leg is raised in the same way. The two support legs can be adjusted independently to improve the adaptability of the entire height-adjustable table to complex terrain.

[0004] Because existing height-adjustable desks have a fixed desktop angle, the desktop support angle cannot be adjusted according to usage needs, and the desktop load-bearing area is fixed, it cannot be adjusted according to usage needs, resulting in poor applicability of height-adjustable desks; therefore, a height-adjustable desk that is easy to adjust is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problems existing in existing technologies, this utility model proposes an easily adjustable height-adjustable table.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The adjustable height table of this utility model includes a support component; two sets of adjustment components for adjusting the tilt angle of the support component are symmetrically installed under the support component, and a height adjustment component for support and height adjustment is installed under each of the two sets of adjustment components, and universal wheels are installed under each of the height adjustment components.

[0007] An extension winding assembly is installed on the side of the support assembly. A steel wire is wound inside the extension winding assembly, and the other end of the steel wire is connected to the upper surface of the support assembly and to the side opposite to the extension winding assembly. Support bars are evenly distributed on the steel wire, and the support bars can be wound inside the extension winding assembly.

[0008] Preferably, the support assembly includes two bearing plates, with splicing plates evenly arranged on the opposite sides of the two bearing plates, and the splicing plates between the two bearing plates are arranged in an alternating manner, and the adjacent splicing plates are slidably fitted together by rib grooves and fixing ribs.

[0009] Preferably, two second-generation electric telescopic rods are installed under the two bearing plates, and the two second-generation electric telescopic rods are parallel to each other and parallel to the bearing plates.

[0010] Preferably, the extended winding assembly includes a winding drum, which is fixedly connected to the side of one of the support plates and parallel to the side of the support plate. A limiting shaft is fixedly connected inside the winding drum, and a hollow shaft is rotatably arranged outside the limiting shaft. A spiral spring is arranged between the hollow shaft and the limiting shaft, and the end of the steel wire is fixedly connected to the outer wall of the hollow shaft. The other end of the steel wire is connected to a fixing strip, and the fixing strip is fixedly connected to the side of another support plate.

[0011] Preferably, a rotating shaft for guidance is provided under the steel wire, and the rotating shaft is rotatably mounted on the side of the bearing plate on which the winding drum is provided via a support member, and is parallel to the side of the bearing plate.

[0012] Preferably, the adjustment assembly includes a U-shaped frame and a worm gear. A fixed shaft is fixedly connected through the opening side of the U-shaped frame. A gear is fixedly connected to the fixed shaft and is located inside the opening of the U-shaped frame. The worm gear is rotatably mounted under the support plate via a mounting plate and meshes with the gear for transmission. Side plates are rotatably mounted at both ends of the fixed shaft and are fixedly connected to the support plate. A motor is connected to the drive shaft of the worm gear and is mounted under the support plate via a fixing component.

[0013] Preferably, the lifting assembly includes a support base, on which a first electric telescopic rod is fixedly connected. The top end of the first electric telescopic rod is fixedly connected to a U-shaped frame, and the casters are installed under the support base.

[0014] Preferably, a wire threading bracket for threading is installed on the same side of both of the bearing plates, and a control panel for control is installed under the side of one of the bearing plates.

[0015] The advantages of this utility model are:

[0016] 1. When the No. 2 electric telescopic rod is extended, the distance between the two bearing plates will be adjusted. The adjacent splicing plates will slide in the rib groove through the fixed ribs. When the distance between the two bearing plates is expanded, the steel wire will be pulled out from the winding drum and laid flat on the expanded bearing plate and splicing plate through the guide of the rotating shaft. At this time, the bearing area of ​​the table can be adjusted under the support of the bearing plate and splicing plate on the support strip.

[0017] 2. When the motor runs, it drives the worm gear to rotate. Since the gear is fixed to the fixed shaft and cannot rotate, the worm gear will rotate around the gear when it rotates. Since the worm gear is installed under the support plate, and the support plate is rotatably connected to the fixed shaft through the side plate, the rotation of the worm gear around the gear will drive the support plate to rotate around the fixed shaft to adjust the support angle of the tabletop to suit different usage needs.

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 scope of protection of the present utility model.

[0034] Please see Figure 1-6 As shown, an adjustable height-adjustable table includes a support assembly 1; two sets of adjustment assemblies 5 for adjusting the tilt angle of the support assembly 1 are symmetrically installed under the support assembly 1, and a height-adjusting assembly 3 for support and height adjustment is installed under each of the two sets of adjustment assemblies 5, and casters 4 are installed under each of the height-adjusting assemblies 3.

[0035] An extension winding assembly 2 is installed on the side of the support assembly 1. A steel wire 27 is wound inside the extension winding assembly 2, and the other end of the steel wire 27 is connected to the upper surface of the support assembly 1 and to the side opposite to the extension winding assembly 2. Support strips 29 are evenly distributed on the steel wire 27, and the support strips 29 can be wound inside the extension winding assembly 2.

[0036] The support assembly 1 includes two support plates 11, and splicing plates 12 are evenly arranged on the opposite sides of the two support plates 11. The splicing plates 12 between the two support plates 11 are arranged in an alternating manner, and the adjacent splicing plates 12 are slidably fitted together by rib grooves 13 and fixed ribs 14.

[0037] Two second-generation electric telescopic rods 8 are installed under the two support plates 11, and the two second-generation electric telescopic rods 8 are parallel to each other and parallel to the support plates 11.

[0038] The extended winding assembly 2 includes a winding drum 21, which is fixedly connected to the side of one of the support plates 11 and parallel to the side of the support plate 11. A limiting shaft 22 is fixedly connected inside the winding drum 21. A hollow shaft 23 is rotatably arranged on the outside of the limiting shaft 22. A spiral spring 24 is arranged between the hollow shaft 23 and the limiting shaft 22. The end of the steel wire 27 is fixedly connected to the outer wall of the hollow shaft 23. The other end of the steel wire 27 is connected to a fixing strip 28, and the fixing strip 28 is fixedly connected to the side of the other support plate 11.

[0039] The steel wire 27 is provided with a rotating shaft 25 for guidance, and the rotating shaft 25 is rotatably mounted on the side of the bearing plate 11 on which the winding drum 21 is provided via a support member 26, and is parallel to the side of the bearing plate 11.

[0040] The adjustment assembly 5 includes a U-shaped frame 51 and a worm gear 55. A fixed shaft 52 is fixedly connected through the opening side of the U-shaped frame 51. A gear 53 is fixedly connected to the fixed shaft 52 and is located inside the opening of the U-shaped frame 51. The worm gear 55 is rotatably mounted under the support plate 11 via a mounting plate 56 and meshes with the gear 53 for transmission. Side plates 54 are rotatably mounted at both ends of the fixed shaft 52 and are fixedly connected to the support plate 11. A motor 57 is connected to the drive shaft of the worm gear 55 and is mounted under the support plate 11 via a fixing component.

[0041] The lifting assembly 3 includes a support base 31, on which a first electric telescopic rod 32 is fixedly connected. The top end of the first electric telescopic rod 32 is fixedly connected to the U-shaped frame 51, and the universal wheels 4 are installed under the support base 31.

[0042] Both of the two support plates 11 are equipped with a wire threading bracket 7 on the same side, and a control panel 6 for control is installed on the lower side of one of the support plates 11.

[0043] During operation, the existing height-adjustable desk has a fixed desktop angle, which cannot be adjusted according to usage needs. The desktop support angle is also fixed, which cannot be adjusted according to usage needs, resulting in poor applicability of the height-adjustable desk. In this solution, the spiral spring 24 will always twist the hollow shaft 23 in the initial state, so that the steel wire 27 is wound on the hollow shaft 23, and the support bar 29 together with the steel wire 27 is wound into the winding drum 21.

[0044] In the initial state, the splicing plate 12 between the two support plates 11 will be spliced ​​together and staggered to form a plane with the two support plates 11 to provide support. The horizontally arranged support bars 29 will be laid flat on the support plates 11 and the splicing plate 12. When adjusting the tabletop bearing area, the two second electric telescopic rods 8 are extended simultaneously. When the second electric telescopic rods 8 extend, the distance between the two support plates 11 will be adjusted. When the two support plates 11 expand and move, they will drive the casters 4 to roll on the ground through the adjustment components 5 and the lifting components 3 below them. At the same time, the two support plates 11 expand. When the time is right, the splicing plates 12 set on the inner side will slide to both sides respectively, and the adjacent splicing plates 12 will slide in the rib groove 13 through the fixed ribs 14 to ensure the support force between the splicing plates 12. When the distance between the two bearing plates 11 increases, the steel wire 27 will be pulled out from the winding drum 21. The pulling out of the steel wire 27 will cause the support bar 29 on it to move out from the winding drum 21 and be laid flat on the expanded bearing plate 11 and splicing plate 12 through the guide of the rotating shaft 25. At this time, the bearing area of ​​the table can be adjusted under the support of the support bar 29 on the bearing plate 11 and splicing plate 12.

[0045] When the desktop's load-bearing angle needs to be adjusted, the motors 57 in the two sets of adjustment components 5 are controlled to operate. When the motors 57 operate, they drive the worm gear 55 to rotate. Since the gear 53 is fixed to the fixed shaft 52 and cannot rotate, when the worm gear 55 rotates, it will rotate around the gear 53. Since the worm gear 55 is installed under the support plate 11, and the support plate 11 is rotatably connected to the fixed shaft 52 through the side plate 54, when the worm gear 55 rotates around the gear 53, it will drive the support plate 11 to rotate around the fixed shaft 52 as the axis, thereby adjusting the desktop's load-bearing angle to suit different usage needs.

[0046] When the No. 1 electric telescopic rod 32 extends or retracts, it can drive the support component 1 to rise or fall, thereby adjusting the table height of the support component 1;

[0047] It achieves the function of adjusting the desktop bearing area and bearing angle, which can meet the usage needs of different scenarios and is more applicable than traditional height-adjustable desks.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
