[0026] Embodiment

[0027] As Figures 1-4As shown, this embodiment provides a torque detection liftable workbench, including a workbench main body 1 and a table top 2, the workbench main body 1 is a rectangular frame structure composed of a plurality of square tubes, the outside of which is covered by a baffle to form the workbench main body 1, the table top 2 is arranged above the workbench main body 1, and the two sides of the bottom of the table top 2 are respectively bolted to the shaft seats 21, and the two shaft seats 21 are respectively connected to connecting rods 32, the top of the connecting rod 32 is hinged to the shaft on the shaft seat 21, and the side of the connecting rod 32 is fixed with a rack 33 by bolts, and the upper part of the workbench main body 1 is provided with a driving mechanism for driving the rack 33 to move up and down, and the bottom of the workbench main body 1 is transmission-connected to the bottom end of the connecting rod 32 by a swing arm mechanism.

[0028] Specifically, the driving mechanism includes two connecting brackets 34 fixedly installed on both sides of the workbench body 1 by bolts, the connecting brackets 34 are provided with round holes, and the connecting brackets 34 are rotatably connected with a first rotating shaft 35, the first rotating shaft 35 passes through the round holes on the two connecting brackets 34, and two gears 36 are fixedly installed on the first rotating shaft 35, and the two gears 36 are respectively engaged with two racks 33, and one end of the first rotating shaft 35 passes through the workbench body 1 and is fixedly connected with a first rotating wheel 31, so that the first rotating wheel 31 is set on the outside of the workbench body 1, and the first rotating wheel 31 is rotated to drive the first rotating shaft 35 to rotate, and the rotation of the first rotating shaft 35 drives the two gears 36 to rotate, and the two gears 36 rotate synchronously to drive the two racks 33 to move synchronously, and the connecting rod 32 moves synchronously with the racks 33, and finally drives the table top 2 to rise and fall.

[0029] Furthermore, a connection seat 37 is bolted and fixedly connected to both sides of the workbench body 1, and the connection seat 37 is arranged on the side of the connecting rod 32 away from the gear 36. The connection seat 37 is rotatably connected to a bearing 38, and the bearing 38 is arranged against the connecting rod 32. The connecting rod 32 is limited and guided by the bearing 38, so that the connecting rod 32 remains vertical during the up and down movement, and the bearing 38 can rotate to reduce the friction between the connecting rod 32 and avoid jamming.

[0030] Specifically, the swing arm mechanism includes two connecting blocks 42 fixedly connected to both sides inside the workbench main body 1. A second rotating shaft 43 is rotatably connected to the two connecting blocks 42. First swing arms 44 are hinged to both ends of the second rotating shaft 43 respectively. A second swing arm 45 is hinged to the end of the first swing arm 44 away from the second rotating shaft 43. The end of the second swing arm 45 away from the first swing arm 44 is hinged to the bottom end of the connecting rod 32. One end of the second rotating shaft 43 penetrates through the workbench main body 1 and is fixedly installed with a second runner 41 by bolts. Limit stop blocks 46 are fixedly connected to both sides inside the workbench main body 1 respectively. The limit stop blocks 46 are arranged below the second swing arm 45. The tabletop 2 rises driven by the gear 36 and the rack 33. The connecting rod 32 drives the second swing arm 45 to move. During the movement of the first swing arm 44 and the second swing arm 45, the second swing arm 45 is limited by the limit stop block 46. After being blocked by the limit stop block 46, the first swing arm 44 and the second swing arm 45 form a dead point structure. At this time, the connecting rod 32 cannot move downward, so that the rising state of the tabletop 2 is locked, and the rising state of the tabletop 2 is maintained. At this time, the tabletop 2 cannot descend. When it is necessary to descend, rotate the second runner 41 to drive the second rotating shaft 43 to rotate. The rotation of the second rotating shaft 43 drives the first swing arm 44 to rotate. The rotation of the first swing arm 44 drives the second swing arm 45 to rotate away from the limit stop block 46, releasing the dead point structure. At this time, the connecting rod 32 can move downward, and the tabletop 2 can be driven to descend through the gear 36 and the rack 33.

[0031] Furthermore, a clamping block 47 is fixedly connected to one side of the workbench main body 1 close to the second runner 41 by bolts. The second rotating shaft 43 penetrates through the clamping block 47. One end of the clamping block 47 is bolted with a hand-tightening bolt 48. By rotating the hand-tightening bolt 48, the clamping block 47 can be tightened. The clamping block 47 clamps the second rotating shaft 43 to make it unable to rotate, so as to ensure the firmness of the dead point structure formed by the first swing arm 44 and the second swing arm 45. When it is necessary to lower the tabletop 2, loosen the hand-tightening bolt 48 to release the restriction on the second rotating shaft 43. At this time, the second runner 41 can be rotated to drive the second rotating shaft 43 to rotate, releasing the dead point structure of the first swing arm 44 and the second swing arm 45. At this time, the first runner 31 can be rotated to lower the tabletop 2.

[0032] Furthermore, a partition plate 16 is fixedly connected to the middle of the workbench main body 1 by bolts. Strip-shaped holes allowing the movement of the first swing arm 44 and the second swing arm 45 are opened on both sides of the partition plate 16. The interior of the workbench is divided into upper and lower cavities by the partition plate 16, and items can be stored. And since the partition plate 16 is provided with strip-shaped holes, it will not affect the activities of the first swing arm 44 and the second swing arm 45.

[0033] Further, a door panel 11 is hinged to the side of the workbench main body 1 through a hinge 13, and a handle 12 is fixedly connected to the door panel 11. By opening the door panel 11 through the handle 12, the interior can be inspected, or items can be taken and placed.

[0034] Further, universal casters 14 are fixedly connected to the four corners of the bottom of the workbench main body 1. The workbench can be conveniently moved through the universal casters 14, and the universal casters 14 are provided with a braking structure, and the universal casters 14 can be locked after reaching the designated position to stop moving.

[0035] Furthermore, an armrest 15 is fixedly connected to the upper part of the side of the workbench main body 1. By pushing the workbench main body 1 through the armrest 15, the operation is convenient.

[0036] The working principle of the present utility model: When the tabletop 2 needs to rise, rotate the first runner 31 to drive the first rotating shaft 35 to rotate. The rotation of the first rotating shaft 35 drives the two gears 36 to rotate. The synchronous rotation of the two gears 36 drives the two racks 33 to move synchronously. The connecting rod 32 moves synchronously with the rack 33, and finally drives the tabletop 2 to rise. After the tabletop 2 rises, the internal swing arm mechanism forms a dead point structure due to the limit stop block 46. Outside, the clamping block 47 is tightened by the hand-tightening bolt 48 to lock the second rotating shaft 43, so that the tabletop 2 maintains the rising state; when the tabletop 2 needs to descend, rotate the hand-tightening bolt 48 to loosen the clamping block 47. The clamping block 47 loosens the second rotating shaft 43. At this time, rotate the second runner 41 counterclockwise to drive the second rotating shaft 43 to rotate. The second rotating shaft 43 drives the first swing arm 44 and the second swing arm 45 to rotate, destroying the dead point structure of the internal rack 33. At this time, rotating the first runner 31 can drive the tabletop 2 to descend.

[0037] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present disclosure, and are not intended to limit them; although the present disclosure has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present disclosure.
