Description

Technical Field

[0001] The present application relates to the technical field of planer workbenches, and in particular to a leveling and supporting structure of a planer expansion workbench. Background Art

[0002] In the woodworking industry, a planer is a machine used to plane and smooth the surface of wood. With the continuous advancement of woodworking technology and the diversification of market demands, higher requirements are being placed on the functionality and flexibility of planers. Traditional planer workbenches are often fixed and limited in area, making them difficult to process large or odd-shaped wood. Therefore, the planer expansion table has emerged, aiming to improve the adaptability and processing efficiency of planers by increasing the workbench area and providing adjustable functions.

[0003] However, the existing planer expansion workbench generally lacks a leveling mechanism. During use, an uneven workbench can easily affect the flatness of wood planing. A small number of adjustable expansion workbenches generally fix the adjustment platform with screws and nuts, and adjust it by manually loosening and tightening the screws and nuts, and then retighten it. The operation is relatively complicated and tedious.

[0004] The above content is only used to assist in understanding the technical solution of this application, and does not mean that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, the present application provides a leveling and support structure for a planer expansion workbench to solve one of the above technical problems.

[0007] In some embodiments, the adjusting screw provides support for the expansion platform, and screwing the adjusting screw can adjust the expansion angle of the expansion platform.

[0008] In some embodiments, the height of the adjustment platform can only be adjusted within the length range of the sliding groove, and two adjacent adjustment grooves are always partially exposed through the square groove.

[0009] In some embodiments, a roller is provided at the end of the support leg, and the roller is mounted on the support leg through a fixing plate.

[0010] In some embodiments, the rolling bar can be leveled using a tool through the cooperation between the square groove and the fixing plate.

[0011] In some embodiments, the expansion platform is disposed on at least one side of the workbench.

[0012] The beneficial effects of this application are: by rotating the adjusting screw in the threaded hole for support, the angle of the expansion platform can be fine-tuned to assist in leveling, the adjustment platform slides in the sliding groove through fasteners, and a flat-head screwdriver and other tools are used to adjust the height of each part of the adjustment platform through the square groove and the adjustment groove, ensuring that the expansion platform and the workbench are flush, and the operation is simple, convenient and fast.

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection of this application.

[0019] In the examples of this application, please refer to Figure 1-3 As shown, the leveling and support structure of the planer expansion workbench mainly includes: a workbench 1, which is provided with a threaded hole 2, and an adjusting screw 3 is rotated in the threaded hole 2; an expansion platform 4 is rotated on the workbench 1, and has two states: unfolded and flipped and folded, including: support legs 401, which are arranged on both sides of the expansion platform 4 and are rotatably connected to the workbench 1. In the unfolded state, one end of the support leg 401 extends into the interior of the workbench 1 and contacts the adjusting screw 3. The support legs 401 are provided with a plurality of groups of staggered square grooves 5 and sliding grooves. 6; the adjustment platform 402 has adjustment slots 7 on both sides corresponding to the square slots 5, the adjustment slots 7 are arranged in pairs and distributed up and down, and the adjustment platform 402 is also provided with mounting holes 8 corresponding to the sliding slots 6, and fasteners 9 are provided in the mounting holes 8 and the sliding slots 6. The adjustment platform 402 is fixed to the support leg 401 by passing the fasteners 9 through the mounting holes 8 and the sliding slots 6; the adjustment platform 402 can be leveled by using tools to reach into the square slots 5 and the adjustment slots 7 and adjust by prying.

[0020] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.

[0021] like Figure 2 As shown, the adjusting screw 3 provides support for the expansion platform 4 . By screwing the adjusting screw 3 and changing the length of the adjusting screw extending out of the threaded hole 2 , the expansion angle of the expansion platform 4 can be adjusted.

[0022] Specifically, the height of the adjustment platform 402 can only be adjusted within the length of the sliding slot 6. The two adjacent adjustment slots 7 are always partially exposed through the square slot 5, so that a tool can always be used to operate in either of the upper and lower adjustment slots 7. The tool used is preferably a flathead screwdriver. The adjustment platform 402 is leveled by reaching into the square slot 5 and the adjustment slot 7 and prying.

[0023] like Figure 1 As shown, a roller rod 10 is provided at the end of the support leg 401, and the roller rod 10 is installed on the support leg 401 through a fixing plate 11. The fixing plate 11 also slides on the support leg 401 through a fastener 9. The setting of the roller rod 10 makes the wood feeding smoother.

[0024] Furthermore, the rolling rod 10 can be leveled using a tool through the cooperation between the square groove 5 and the fixing plate 11 so that the rolling rod 10 and the adjustment platform 402 are flush.

[0025] In some embodiments, the expansion platform 4 is disposed on at least one side of the workbench 1 .

[0026] Specifically, the fastener 9 fixes the adjustment platform 402 on the support leg 401. Except for using tools, the fastener 9 cannot slide easily in the sliding groove 6 in daily use. Compared with the adjustable platform fixed only with screws and nuts, the square groove 5 and the adjustment groove 7 are added to cooperate and an operating tool is introduced for adjustment without loosening the screws and nuts. It is only necessary to directly level the adjustment platform 402 and the roller 10, thereby improving operating efficiency.
