Description

Technical Field

[0001] This utility model belongs to the field of door and window processing technology, specifically relating to a workbench. Background Technology

[0002] Doors and windows are an essential component of buildings, primarily serving the functions of ventilation and light transmission. Depending on their location, doors and windows are classified as enclosure components or partition components. During their production, doors and windows require assembly, an operation that must be carried out on a workbench.

[0003] Existing processing tables are generally composed of a fixed base frame and a table surface. Although they can support door and window components, they are still relatively limited in actual use. When dealing with doors and windows of different specifications, there are also worktables that can be raised or lowered or whose table surface area can be adjusted, but most of them are single designs and cannot be coordinated, resulting in poor applicability and high limitations. Utility Model Content

[0004] In view of this, the present invention provides a workbench that can achieve rapid and coordinated adjustment of the table height and support area through the cooperation of a lifting unit and an adjustment component system, which can not only adapt to the differences in the height of the operators, but also match the working needs of doors and windows of different sizes.

[0005] To solve the above-mentioned technical problems, this utility model provides a workbench, including a base frame and a lifting unit mounted thereon. The lifting unit includes rectangular cylinders symmetrically arranged at the four corners of the upper end of the base frame. A platform is slidably connected between the four rectangular cylinders. A threaded cylinder is rotatably connected to the upper end of the base frame. A lead screw is provided at the lower end of the platform, and the lead screw is threadedly connected to the threaded cylinder. An adjustment component for adjusting the support area is also provided on the platform, and a drive component for driving the threaded cylinder to rotate is provided on the base frame. This enables rapid and coordinated adjustment of the platform height and the support area, which can adapt to differences in operator height and meet the operational needs of doors and windows of different sizes.

[0006] The adjustment component includes symmetrically arranged slides on the upper end of the platform. A sliding support frame one is slidably connected to one side of the two slides, and a sliding support frame two is slidably connected to the other side of the two slides, which serves to adjust the support area.

[0007] The adjustment assembly also includes a gear located in the middle of each slide groove. Slots are provided on the sides of both sliding support frame one and sliding support frame two near each gear. A rack plate is provided in each slot. The gear meshes with two adjacent rack plates on the same side, thus achieving rapid transmission.

[0008] The drive assembly includes a fixed plate mounted on the upper end of the base frame. A rotating hole on the fixed plate is rotatably connected to the upper end of the threaded cylinder. The upper end of the fixed plate is provided with a mounting cavity. A worm gear ring is provided on the outer arc surface of the inner cavity of the threaded cylinder. A worm is rotatably connected to one side of the upper end of the fixed plate. The worm meshes with the worm gear ring, thus achieving the function of rapid transmission.

[0009] A folding cylinder is provided between the fixed plate and the frame, and the lead screw is located inside the folding cylinder, which serves to seal the lead screw.

[0010] The top of the rectangular tube and the fixed plate are flush to prevent them from affecting the lifting and moving of the platform.

[0011] The sliding support frame 1, sliding support frame 2 and the top of the platform are flush, thus ensuring the integrity of the platform surface.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. When workers are processing doors and windows, they rotate the worm gear. As the worm gear rotates, it drives the threaded cylinder to rotate through the worm wheel ring that meshes with it. During the rotation of the threaded cylinder, it drives the platform that is slidably connected in the four rectangular tubes to rise and fall synchronously through the screw that is threaded to it. The design that the upper ends of the rectangular tubes and the fixed plate are flush ensures the structural balance of the platform during the lifting and lowering of the platform. This ultimately achieves rapid and coordinated adjustment of the platform height and support area, which can not only adapt to the differences in the height of the operators, but also match the working needs of doors and windows of different sizes.

[0014] 2. When it is necessary to adjust the support area, the operator moves sliding support frame one or sliding support frame two. When one of them moves, the meshing transmission between the gear in the middle of the slide groove and the rack plates on both sides will cause sliding support frame one or sliding support frame two on both sides to slide in opposite directions simultaneously to expand or shrink the support range.

[0015] 3. The folding cylinder can fold synchronously with the lifting and lowering of the platform to protect the precision of its internal threaded cylinder and lead screw thread connection. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] This embodiment provides a workbench, such as Figure 1-4 As shown: It includes a base frame 100 and a lifting unit mounted on it. The lifting unit includes rectangular tubes 200 symmetrically arranged at the four corners of the upper end of the base frame 100. A platform 201 is slidably connected between the four rectangular tubes 200. A threaded tube 202 is rotatably connected to the upper end of the base frame 100. A lead screw 203 is provided at the lower end of the platform 201. The lead screw 203 is threadedly connected to the threaded tube 202. An adjustment component for adjusting the support area is also provided on the platform 201. A drive component for driving the threaded tube 202 to rotate is provided on the base frame 100. The uppermost ends of the rectangular tubes 200 and the fixed plate 400 are flush.

[0023] When workers are processing doors and windows, the threaded cylinder 202 is driven to rotate by the drive assembly. During the rotation of the threaded cylinder 202, the screw 203 connected to it drives the platform 201, which is slidably connected in the four-corner rectangular cylinder 200, to rise and fall synchronously. At the same time, the screw 203 is located in the folding cylinder 500 to ensure the stability of the movement. The flush design of the upper ends of the rectangular cylinder 200 and the fixed plate 400 ensures the structural balance when the platform is raised and lowered. When it is necessary to adjust the support area, the operator can adjust the component to slide in the opposite direction synchronously to expand or shrink the support range, thus achieving rapid and coordinated adjustment of the platform height and support area. This can accommodate the differences in the height of the operators and match the operation needs of doors and windows of different sizes.

[0024] like Figure 1-4As shown, the adjustment assembly includes symmetrically arranged slide grooves 300 on the upper end of the platform 201. A sliding support frame 301 is slidably connected to one side between the two slide grooves 300, and a sliding support frame 302 is slidably connected to the other side between the two slide grooves 300. The adjustment assembly also includes gears 303 disposed in the middle of each slide groove 300. Slots are provided on the sides of the sliding support frame 301 and the sliding support frame 302 near each gear 303. A rack plate 304 is provided in each slot. The gears 303 are respectively meshed with two adjacent rack plates 304 on the same side. The uppermost ends of the sliding support frame 301, the sliding support frame 302 and the platform 201 are flush. The sliding support frame 301 or the sliding support frame 302 is U-shaped and the openings are opposite each other. The sliding support frame 302 is located inside the sliding support frame 301.

[0025] When the support area needs to be adjusted, the operator moves the sliding support frame 301 or the sliding support frame 302. When one of them moves, the meshing transmission between the gear 303 in the middle of the slide groove and the rack plates 304 on both sides causes the sliding support frames 301 or 302 on both sides to slide in opposite directions simultaneously to expand or shrink the support range, thus achieving rapid and coordinated adjustment of the table height and support area.

[0026] like Figure 2-3 As shown, the drive assembly includes a fixed plate 400 disposed on the upper end of the base frame 100. A rotating hole on the fixed plate 400 is rotatably connected to the upper end of the threaded cylinder 202. The upper end of the fixed plate 400 is provided with a mounting cavity 401. A worm gear ring 402 is provided on the outer arc surface of the inner cavity of the threaded cylinder 202. A worm 403 is rotatably connected to one side of the upper end of the fixed plate 400. The worm 403 is meshed with the worm gear ring 402.

[0027] When the worm 403 is rotated, the threaded cylinder 202 is driven to rotate through the worm wheel ring 402 that meshes with it. At the same time, after rotating to the position, the self-locking characteristic of the meshing between the worm wheel ring 402 and the worm 403 can be used to prevent the threaded cylinder 202 from rotating.

[0028] like Figure 1-3 As shown, a folding cylinder 500 is provided between the fixed plate 400 and the frame 201. The lead screw 203 is located inside the folding cylinder 500. The folding cylinder 500 can be folded synchronously when the frame 201 is raised and lowered to protect the accuracy of the threaded connection between its inner threaded cylinder 202 and the lead screw 203.

[0029] The working principle of the workbench provided by this utility model is as follows: When the worker is processing doors and windows, the worm gear 403 is rotated. When the worm gear 403 rotates, it drives the threaded cylinder 202 to rotate through the worm wheel ring 402 that meshes with it. During the rotation of the threaded cylinder 202, the screw 203 connected to it drives the frame 201, which is slidably connected in the four-corner rectangular cylinder 200, to rise and fall synchronously. At the same time, the screw 203 is located in the folding cylinder 500 to ensure the stability of the movement. The upper ends of the rectangular cylinder 200 and the fixed plate 400 are flush. The design ensures structural balance during platform lifting. When the support area needs to be adjusted, the operator moves sliding support frame 1 301 or sliding support frame 2 302. When one of them moves, the meshing transmission between the gear 303 in the middle of the slide groove and the rack plates 304 on both sides causes the sliding support frames 1 301 or 2 302 on both sides to slide in opposite directions simultaneously to expand or shrink the support range. This achieves rapid and coordinated adjustment of the platform height and support area, which can adapt to differences in operator height and match the operational needs of doors and windows of different sizes.

[0030] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
