Description

Technical Field

[0001] This utility model relates to the field of workbench technology, specifically a movable workbench. Background Technology

[0002] Mobile workbenches are widely used in workshops, warehouses, laboratories, and homes due to their flexibility. Existing mobile workbenches typically have casters mounted on the legs of a fixed workbench. While this achieves mobility, it still has some shortcomings in practical use.

[0003] CN222060262U discloses a movable workbench, "including a tabletop, four sets of legs fixedly connected to the bottom of the tabletop, and connecting members fixedly connected to the bottom of each of the four sets of legs. Rollers are movably sleeved inside the connecting members, connecting shafts are fixedly connected inside the rollers, gears are fixedly connected to the outer wall of the connecting shafts, limit grooves are formed inside the legs, limit blocks are slidably connected to the surface of the limit grooves, and connecting rods are fixedly connected to the side of the limit blocks." This movable workbench, by... Pulling the connecting rod six at the top causes the bottom of the stop block to engage with the top of the gear, thus fixing the rotation of the gear. This stops the rotation of the gear and the internal connecting shaft, thereby fixing the rotation of the roller and securing the worktable. Locking the roller can reduce the risk of accidents caused by accidental movement or slippage. However, this solution only provides the function of fixing the roller and does not have the function of adjusting the height and size of the worktable. It cannot adjust the height according to the user's height and current usage situation, making it inconvenient to use and having poor adaptability.

[0004] Therefore, a movable workbench is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] In one embodiment, such as Figures 1-6 As shown, the movable workbench includes an operating table 1, with two adjustment components symmetrically arranged below the operating table 1 and an extension component arranged above the operating table 1; A support component is provided below the adjustment component, and a sliding component is provided inside the support component; The adjustment assembly includes a fixed column 2, which is located below the operating table 1. A lifting seat 20 is slidably mounted on the upper end of the fixed column 2. The upper end of the lifting seat 20 is fixedly connected to the lower surface of the operating table 1. A plurality of limiting holes 21 are arrayed through one side of the fixed column 2. A limiting box 22 is fixedly connected to one side of the lifting seat 20. A limiting plate 24 is slidably mounted on one side of the limiting box 22. A limiting column 23 is fixedly connected to one side of the limiting plate 24. One end of the limiting column 23 passes through one side of the limiting box 22 and is slidably connected to the adjacent limiting hole 21. A plurality of third springs 26 are fixedly connected to the other side of the limiting plate 24. The other end of the third spring 26 is fixedly connected to one side of the adjacent limiting box 22. A pull rod 25 is slidably mounted on one side of the limiting box 22. The pull rod 25 is U-shaped and its two ends pass through one side of the limiting box 22 and are fixedly connected to one side of the adjacent limiting plate 24. In this embodiment, when the height of the operating platform 1 needs to be adjusted, the user pulls the U-shaped lever 25 outward. The lever 25 causes the limiting plate 24 to slide within the limiting box 22, compressing the third spring 26. At the same time, the limiting post 23, which is fixedly connected to the limiting plate 24, exits from the limiting hole 21 corresponding to the fixed post 2, thereby releasing the lock. At this time, the user can drive the operating platform 1 and the lifting seat 20 fixed thereto to slide up and down along the fixed post 2 until the ideal height is reached. Then, the user releases the lever 25. Under the restoring force of the third spring 26, the limiting plate 24 and the limiting post 23 reset, and the limiting post 23 automatically inserts into the limiting hole 21 corresponding to the height, achieving fast and reliable locking and completing the height adjustment.

[0024] In one embodiment, such as Figure 2 As shown, the extension assembly includes two extension plates 19, which are respectively hinged to the upper sides of the worktable 1. The extension plates 19 can be folded and placed on the upper surface of the worktable 1. When a larger working area is required for large-scale operations, the user can flip up the two extension plates 19 folded on the upper surface of the worktable 1 so that they are on the same plane as the worktable 1, thereby effectively expanding the working area. After the operation is completed, the extension plates 19 can be folded down again so that they are close to the upper surface of the worktable 1 to save space and facilitate storage and movement.

[0025] In one embodiment, such as Figure 4 As shown, the sliding assembly includes a mounting plate 6, which is a cross-shaped plate and slidably disposed in the middle of the support assembly. Several caster rods 7 are fixedly connected to the lower surface of the mounting plate 6, and several casters 8 are fixedly connected to the lower surface of the caster rods 7. The support assembly includes a support rod 3, of which several are provided, and their upper ends are fixedly connected to the lower surface of the operating table 1. A connecting plate 4 is fixedly connected to the middle of the support rod 3. Several lifting components are disposed between the mounting plate 6 and the connecting plate 4. The support assembly consists of the support rods 3 and the connecting plate 4 forming the main support frame. The mounting plate 6 in the sliding assembly moves the entire worktable via the caster rods 7 and casters 8 below it. When movement is required, the mounting plate 6 descends under the action of the lifting components, causing the casters 8 to contact the ground and lift the entire device, allowing for easy pushing.

[0026] In one embodiment, such as Figure 5As shown, the lifting assembly includes a slide groove 9, which is formed on the upper surface of the connecting plate 4. A sleeve 10 is slidably disposed inside the slide groove 9. The upper end of the sleeve 10 is fixedly connected to one side of the lower surface of the adjacent mounting plate 6. A first spring 13 is fixedly connected between the slide groove 9 and the sleeve 10. A limit assembly is provided between the sleeve 10 and the slide groove 9. A limit groove 11 is formed inside the slide groove 9. A limit block 12 is fixedly connected to the lower end of the sleeve 10. The limit block 12 is slidably disposed inside the limit groove 11. When... When the workbench needs to be moved, press down on the mounting plate 6. The mounting plate 6 drives the sleeve 10 to slide down in the groove 9 of the connecting plate 4, compressing the first spring 13. At the same time, the limiting block 12 at the lower end of the sleeve 10 slides down along the limiting groove 11, ensuring the stability of the downward process. At this time, the caster 8 extends and contacts the ground, lifting the base 5 off the ground. After moving into place, lift the mounting plate 6 upward. Under the restoring force of the first spring 13, the sleeve 10 and the mounting plate 6 move upward as a whole, the caster 8 leaves the ground, and the base 5 is stably supported on the ground again.

[0027] In one embodiment, such as Figure 4 As shown, a snap-fit ​​assembly is provided at each end of the mounting plate 6 to ensure the stability of the moving assembly.

[0028] In one embodiment, such as Figure 5 As shown, the latching assembly includes two through slots 18, symmetrically arranged on both sides of one end of the mounting plate 6. A latching plate 15 is slidably disposed inside each through slot 18. The upper ends of the two latching plates 15 extend through the upper surface of the mounting plate 6, and latching blocks 16 are fixedly connected to the lower ends of the two latching plates 15. A second spring 17 is fixedly connected to one side of each latching plate 15, and one end of the second spring 17 is fixedly connected to the inner side of an adjacent through slot 18. A latching groove 14 is provided on both sides of the upper surface of the connecting plate 4, and the latching groove 14 is respectively connected to the adjacent latching block. The lower end of plate 15 is connected by a snap-fit. When the worktable is moved into place and needs to be fixed, after the lifting assembly raises the mounting plate 6 to the highest point, the user squeezes the upper ends of the two snap-fit ​​plates 15 inwards. The snap-fit ​​plates 15 slide in the through groove 18, compressing the second spring 17 and causing the snap-fit ​​block 16 at its lower end to disengage from the snap-fit ​​groove 14 on the connecting plate 4. When released, under the restoring force of the second spring 17, the snap-fit ​​plates 15 and snap-fit ​​block 16 pop outwards, so that the snap-fit ​​block 16 is just locked into the snap-fit ​​groove 14, thereby firmly locking the mounting plate 6 in the raised position, ensuring that the caster wheel 8 is suspended and the worktable is stable and does not move.

[0029] In one embodiment, such as Figure 3 As shown, each of the support rods 3 is fixedly connected to a base 5 at its lower end to stabilize the whole structure.

[0030] In one embodiment, such as Figure 2 As shown, a horizontal plate is fixedly connected to the upper end of the support rod 3, and the upper surface of the horizontal plate is fixedly connected to the lower end of the fixed column 2. The support assembly and the lifting assembly are fixed by the horizontal plate.

[0031] The above embodiments disclose a movable workbench, wherein height adjustment is achieved through an adjustment component. The user pulls the U-shaped lever 25 outward, causing the limiting plate 24 to compress the third spring 26 and disengage the limiting post 23 from the limiting hole 21 of the fixed post 2, thus adjusting the workbench 1 to a suitable height. Releasing the lever 25 drives the third spring 26 to insert the limiting post 23 into a new limiting hole 21 to complete locking. The work surface is expanded through a hinged extension plate 19, which can be flipped up to increase the work surface or folded to save space. Switching between movable and fixed modes is the core function: when movement is required, the mounting plate 6 is pressed down. The first spring 13 is compressed by the sleeve 10 and slides down the slide groove 9, causing the caster wheel 8 to touch the ground and lift the base 5, which can then be pushed. When it needs to be fixed, the mounting plate 6 is lifted up, the first spring 13 returns to its original position and rises, and then the buckle plate 15 is pinched inward through the buckle assembly to compress the second spring 17 so that the buckle block 16 disengages from the buckle groove 14. After being released, the buckle block 16 is locked into the buckle groove 14 under the action of the second spring 17, locking the mounting plate 6 in a high position. At this time, the caster wheel 8 is off the ground and the base 5 is stably supported. Throughout the process, the cooperation between the limit block 12 and the limit groove 11 ensures the stability of the lifting.

[0032] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
