Description

Technical Field

[0001] This invention belongs to the field of workbench technology, specifically relating to a combined oblique cutting saw workbench. Background Technology

[0002] A miter saw is an indispensable power tool in woodworking. To achieve stable, precise cuts, it is usually used in conjunction with a dedicated workbench support. For example, Chinese invention patent CN215282338U discloses a foldable and secure miter saw support. It features a locking fastener under the workbench, which locks the legs to the bottom of the workbench after the legs are folded, effectively preventing accidental unfolding during storage and transportation and improving portability.

[0003] However, this workbench is a compact support designed for small workpiece operations. Its main body consists of two long rods, and even with the extension rods at both ends, the effective support span is very limited due to the physical limitations of the internal interlocking mechanism. When dealing with large workpieces, the support becomes unusable due to insufficient support length. Furthermore, the extension structure lacks independent ground support, relying solely on a cantilever beam-like interlocking method for load-bearing, resulting in poor rigidity and difficulty in supporting the weight of large workpieces, further limiting its application in large-scale work scenarios. Summary of the Invention

[0004] This invention addresses the technical problems of existing technologies being unable to meet the processing needs of large workpieces and having poor rigidity of extended structures. It provides a combined oblique cutting saw workbench, which has auxiliary tabletops with fixed and flipping parts at both ends of the main tabletop, and uses a folding guide mechanism to achieve automatic locking of the synchronous linkage between the legs and the tabletop for unfolding and retracting.

[0005] The above-mentioned technical problem of the present invention is solved by the following technical solution: a combined miter saw workbench, including a main table for fixing the miter saw, auxiliary tabletops at both ends of the main table, and a support frame for supporting the two auxiliary tabletops. A lead screw seat for fixing the cutting saw is provided on the main table. The auxiliary tabletops include a fixing part fixedly connected to the main table and a flipping part hinged to the fixing part. The support frame is connected to the flipping part of the auxiliary table. A folding guide mechanism is provided between the support frame and the fixing part. The folding guide mechanism includes a connecting rod connecting the fixing part and the support frame. A sliding groove is provided at the lower part of the connecting rod. A limiting kit is movably sleeved on the sliding groove. The limiting kit includes a sliding sleeve provided on the support frame, a locking block provided in the sliding sleeve, and a hook connected to the support frame. The hook passes through the sliding sleeve and the sliding groove and is connected to the connecting rod.

[0006] Preferably, the connecting rod has a first notch and a second notch on one side, both of which are located on one side of the slide groove. The first notch is flush with the upper end of the slide groove, and the second notch is flush with the lower end of the slide groove. The locking block is hinged to the sliding sleeve and is located on the side of the connecting rod near the first and second notches. As the leg folds inward, the locking block slides upward along one side of the connecting rod and engages with the upper first notch to form a folding lock. Conversely, as the leg unfolds outward, the locking block slides downward along one side of the connecting rod and engages with the lower second notch to form an unfolding lock.

[0007] Preferably, the main table includes two parallel rods, on which the lead screw seat is provided. A first hook assembly for maintaining the overall folded state of the workbench is vertically provided at the connection between the main table and the fixing part. A second hook assembly is also provided horizontally between the fixing part and the flipping part. The first hook assembly and the second hook assembly have the same structure.

[0008] Preferably, both the first hook assembly and the second hook assembly include a base for mounting the first hook assembly or the second hook assembly, a U-shaped member hinged to the base, and a hanging member hinged to the U-shaped member; the hanging member includes a first plate in a three-fold shape on both sides, a second plate connected between the two first plates, and a movable plate above the second plate; the lower part of the first plate is provided with a movable groove, and both ends of the movable plate are slidably embedded in the movable groove; the second plate is provided with a through hole in the middle, and a short rod passes through the through hole; one end of the short rod is provided with a buckle plate with a hole, and the other end of the short rod is connected to the movable plate; a spring is sleeved on the short rod, the upper end of the spring abuts against the movable plate, and the lower end of the spring abuts against the second plate.

[0009] Preferably, the base of the first hook assembly is fixed to the end of the fixing part, and the bottom of the flipping part is provided with a first hook, which can be connected to the buckle plate in the first hook assembly; the base of the second hook assembly is fixed to the bottom surface of the fixing part, and the end of the flipping part is provided with a second hook, which can be connected to the buckle plate in the second hook assembly.

[0010] Preferably, the tripod includes two diagonally arranged leg poles, a first horizontal bar and a second horizontal bar connected laterally between the two leg poles, the first horizontal bar connecting the upper ends of the two leg poles, the first horizontal bar being located above the second horizontal bar, and the hook being connected to the second horizontal bar.

[0011] Preferably, the bottom surface of the fixing part is provided with mounting seats for mounting the legs on both sides. An auxiliary component is coaxially sleeved on the outside of the first crossbar. Both ends of the auxiliary component are provided with a pair of first limiting protrusions. The mounting seat is provided with a second limiting protrusion located outside the auxiliary component. As the flipping part folds inward, the first limiting protrusion abuts against the second limiting protrusion, thereby driving the legs and the folding guide mechanism to fold synchronously. Conversely, as the flipping part unfolds outward, the first limiting protrusion abuts against the second limiting protrusion, thereby driving the legs and the folding guide mechanism to unfold synchronously.

[0012] In summary, the present invention has the following advantages compared with the prior art: This invention provides auxiliary tabletops with a fixing part and a flipping part at both ends of the main tabletop, and connects the legs using a folding guide mechanism, so that the legs can move synchronously with the flipping part. By means of the abutting action between the first limiting protrusion on the auxiliary part and the second limiting protrusion on the mounting base, it can be ensured that the flipping part drives the legs to move synchronously during the flipping operation, effectively improving the ease of operation of the workbench.

[0013] This invention utilizes the locking block in the folding guide mechanism to engage with the first and second notches on the connecting rod to achieve automatic locking and positioning of the tripod in both unfolded and folded states. At the same time, by adding a first hook assembly and a second hook assembly, the workbench is locked in its folded storage state and unfolded use state, respectively. This improves the structural stability of the workbench during use while making it portable and easy to store, thus balancing portability and structural stability. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Example:

[0018] like Figures 1 to 8 As shown, this embodiment provides a combined miter saw workbench, including a main table 1, an auxiliary table 2, and a support frame 3. The main table 1 is used to fix and install the miter saw equipment. The main table 1 includes two parallel rods 16, and a lead screw seat 4 is fixedly installed on the rods 16 for fixing the cutting saw.

[0019] Auxiliary worktables 2 are symmetrically arranged at the left and right ends of the main worktable 1 to extend the support area of ​​the worktable and adapt to the support requirements of large-sized workpieces. Each auxiliary worktable 2 includes a fixed part 5 and a flipping part 6. The fixed part 5 is fixedly connected to the end of the main worktable 1, and the flipping part 6 is hinged to the outside of the fixed part 5, thereby completing the extension and folding of the flipping part 6. The legs 3 used to support the auxiliary worktable 2 are correspondingly connected to the bottom end of the flipping part 6 of the auxiliary worktable 2, and synchronously complete the unfolding and folding with the flipping action of the flipping part 6.

[0020] In this embodiment, a folding guide mechanism 7 is provided between the fixed part 5 of the leg 3 and the auxiliary platform 2. The folding guide mechanism 7 includes a connecting rod 8, and a vertical slide groove 9 is provided at the lower part of the connecting rod 8. A limiting kit 10 is movably sleeved on the slide groove 9. The limiting kit 10 is fixedly engaged with the leg 3. The connecting rod 8 can slide up and down along the slide groove 9 to realize position adjustment and locking.

[0021] The limiting kit 10 includes a sliding sleeve 11, a locking block 12, and a hook 13. The sliding sleeve 11 is fixedly installed on the inner side of the leg 3 at a corresponding position, and the locking block 12 is hinged inside the sliding sleeve 11. The hook 13 is fixedly connected to the leg 3 and passes through the sliding groove 9 of the sliding sleeve 11 and the connecting rod 8 in sequence, so as to realize the movable sleeve engagement between the limiting kit 10 and the connecting rod 8 and ensure the linkage of the overall structure.

[0022] In this embodiment, the connecting rod 8 has a first notch 14 and a second notch 15 on the side near the locking block 12. Both notches are fitted to the side of the slide groove 9 and are distributed vertically. The first notch 14 is flush with the upper end of the slide groove 9, and the second notch 15 is flush with the lower end of the slide groove 9. Both notches are slot structures adapted to the locking block 12, enabling the locking block 12 to be embedded and positioned. The locking block 12 is fitted to the side of the connecting rod 8 with the notch and can slide up and down along the side of the connecting rod 8.

[0023] When the workbench is folded and stored, the flipping part 6 of the auxiliary table surface 2 is flipped inward. The flipping part 6 drives the bottom leg 3 to fold inward in sync. The leg 3 drives the limiting kit 10 to slide upward relative to the connecting rod 8. The locking block 12, which is hinged in the sliding sleeve 11, moves upward along the side of the connecting rod 8 and is embedded in the first notch 14 at the upper end. Through the locking block 12 and the first notch 14, the leg 3 is automatically locked in the folded state, which effectively prevents the leg 3 from becoming loose after storage.

[0024] When the workbench is unfolded, the flipping part 6 of the auxiliary table surface 2 is flipped outward, which drives the leg 3 to unfold outward. The leg 3 simultaneously drives the limiting kit 10 to move down along the side of the connecting rod 8. The locking block 12 slides along and finally embeds into the second notch 15 at the lower end. By locking the locking block 12 and the second notch 15, the leg 3 is locked in the fully unfolded working state, ensuring the overall support stability of the workbench.

[0025] In this embodiment, the stand 3 includes two symmetrically arranged obliquely positioned leg rods 32. A first horizontal bar 33 and a second horizontal bar 34 are horizontally fixedly connected between the two leg rods 32 for connecting them. The first horizontal bar 33 is connected to the upper end of the two leg rods 32, and the second horizontal bar 34 is located below the first horizontal bar 33. The hook 13 of the folding guide mechanism 7 is fixedly connected to the middle of the second horizontal bar 34 to ensure balanced force and smoother linkage transmission.

[0026] To achieve synchronous linkage of the flipping section 6, the legs 3, and the folding guide mechanism 7, mounting seats 35 for assembling the legs 3 are fixedly installed on both sides of the bottom surface of the fixing part 5 of the auxiliary platform 2. An auxiliary part 36 is coaxially sleeved on the outside of the first crossbar 33. A pair of first limiting protrusions 37 are symmetrically arranged at both ends of the auxiliary part 36. A second limiting protrusion 38 extends from the inside of the mounting seat 35 and is located on the outside of the auxiliary part 36, abutting against the first limiting protrusion 37. During the inward folding of the flipping section 6, the auxiliary part 36 moves synchronously with the legs 3. The first limiting protrusion 37 at the end abuts against the second limiting protrusion 38 on the mounting seat 35, limiting the movement. The limiting force drives the legs 3 as a whole and the folding guide mechanism 7 to complete the folding action synchronously. During the outward unfolding of the flipping section 6, the legs 3 and the folding guide mechanism 7 unfold synchronously through the opposite abutting limiting force.

[0027] In this embodiment, to further improve the stability of the workbench in its folded and unfolded states, two sets of identical hook assemblies are provided on the workbench, namely a first hook assembly 17 and a second hook assembly 18. The first hook assembly 17 is vertically arranged and installed at the connection between the main table surface 1 and the fixing part 5 of the auxiliary table surface 2, and is used to maintain the overall folded state of the workbench. The second hook assembly 18 is horizontally arranged and installed at the connection between the fixing part 5 and the flipping part 6, and is used to lock the unfolded flipping part 6.

[0028] Both the first hook assembly 17 and the second hook assembly 18 include a base 19, a U-shaped component 20, and a hanging component 21. The base 19 serves as the mounting base for either the first hook assembly 17 or the second hook assembly 18 and can be fixed to the mounting surface. The U-shaped component 20 is hinged to the base 19. The hanging component 21 is hinged to the U-shaped component 20. The hanging component 21 includes two symmetrically arranged three-fold first plates 22, a second plate 23 connected between the bottoms of the two first plates 22, and a movable plate 24 located above the second plate 23. The lower parts of the two first plates 22 are symmetrically provided with elongated movable grooves 25. The left and right ends of the movable plate 24 are slidably embedded in the movable grooves 25 on the corresponding sides and can slide up and down along the movable grooves 25.

[0029] A through hole 26 is provided at the center of the second plate 23, and a short rod 27 is vertically inserted through the through hole 26. A perforated buckle plate 29 is fixedly installed at the bottom end of the short rod 27 for matching and locking with the hook; the top end of the short rod 27 is fixedly connected to the middle of the movable plate 24. A spring 28 is sleeved on the rod body of the short rod 27. The spring 28 is vertically arranged, with its upper end abutting against the bottom surface of the movable plate 24 and its lower end abutting against the upper surface of the second plate 23. The elastic extension and contraction of the spring 28 provides an elastic force for the hanging part 21 to automatically lock and reset, thereby realizing the elastic pressing and locking of the buckle plate 29.

[0030] In this embodiment, the base 19 of the first hook assembly 17 is fixed to the end of the fixing part 5 of the auxiliary table 2. A first hook 30 is fixedly provided at the bottom of the flipping part 6. When the workbench is folded and stored, the first hook 30 is engaged with the buckle plate 29 of the first hook assembly 17, and the workbench is folded and locked by the elastic locking structure of the first hook assembly 17. The base 19 of the second hook assembly 18 is horizontally fixed to the bottom surface of the fixing part 5. A second hook 31 is fixed to the end of the flipping part 6 facing the fixing part 5. After the flipping part 6 is flipped open, the second hook 31 engages with the buckle plate 29 of the second hook assembly 18 to achieve locking.

[0031] The working process of this invention is as follows: During operation, the first hook assembly 17 is released from its lock, and the two side flipping parts 6 are flipped up and unfolded. At this time, the second hook assembly 18 is locked and engaged. Simultaneously, the flipping part 6 is driven by the auxiliary part 36 to unfold the two side legs 3 outward. The limiting kit 10 of the folding guide mechanism 7 is automatically engaged in the unfolded state, and the workbench is formed as a whole. The oblique cutting saw can then be installed for material cutting.

[0032] When storing, release the lock of the second hook assembly 18, flip the two sides 6 downwards and fold them down. The flip parts 6 are linked to the bracket 3 by the auxiliary parts 36 and retract inwards. The folding guide mechanism 7 automatically locks the folded state. At the same time, the first hook assembly 17 is fastened and locked, so that the workbench is in a compact folded state, which greatly reduces the space occupied and makes it easy to store and transport.

[0033] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
