Description

Technical Field

[0001] The utility model relates to a cutting machine accessory, in particular to a reversible workbench. Background Art

[0002] When the cutting machine is working, a workbench is required to provide support for the cutting machine. The utility model patent with publication number CN202984601U discloses a reversible workbench for molds: it is mainly composed of a workbench frame and a double-sided template. The middle of the two ends of the double-sided template are respectively connected with a reversing shaft, and the workbench frame is correspondingly provided with bearings. The two are rotatably connected, and the double-sided template can be flipped up and down 180 degrees. Template brackets are installed on both ends of the double-sided template, and a limit pin seat is correspondingly provided on the workbench frame. The limit pin in the limit pin seat is inserted into the groove of the template bracket to complete the fixation of the double-sided template. This solution ensures the stability of the table top, but when flipping the workbench panel, the limit pins need to be removed one by one, and the operation steps are complicated. The overall weight of the cutting machine is large, and the flipping of the table top is uncontrollable during the removal of the limit pins. Utility Model Content

[0003] Purpose of the utility model: The purpose of the utility model is to provide a reversible workbench that is easy to operate and has high stability.

[0004] Technical solution: The utility model is a reversible workbench, comprising a table top and a bracket. The two ends of the center line of the table top are rotatably connected by a rotating shaft and a bracket. A pin for supporting the table top is provided on the bracket on one side of the rotating shaft. One end of the pin is provided with an inclined surface, and the other end is provided with a first return spring. When the table top rotates to the bottom of the pin, the inclined surface pushes the pin to retract into the bracket. Press down on the side of the table top where no pin is provided, or lift up on the side where the pin is provided, so that the table top is tilted and flipped nearly 180°. The table top pushes the pin to slide and retract along the bracket. When the table top returns to the horizontal level, the pin is pushed out by the first return spring. The top surface of the pin is tangent / parallel to the bottom of the table top, supporting the table top at the bottom of the table top. The flipping process is simple to operate, and the controllability and stability of the table top flip are high.

[0005] Preferably, the pin is slidably connected to the bracket via a positioning sleeve, and the first return spring is arranged between the pin and the positioning sleeve.

[0006] Preferably, in order to limit the sliding distance of the pin shaft and prevent the pin shaft from rotating, a protruding stop pin is provided in the pin shaft sleeve, and a groove for accommodating the stop pin is provided in the middle of the pin shaft.

[0007] Preferably, in order to further ensure the stability of the table, a latch for locking the table is provided on the side of the top of the bracket away from the pin, and the latch is slidably connected to the bracket. Pulling the latch outward and pressing down on the table can complete the table flipping operation.

[0008] Preferably, the latch is connected to the bracket via a latch sleeve, and a second return spring is provided between the latch and the latch sleeve. When the latch is pulled outward, the latch can automatically rebound.

[0009] Preferably, the latch is connected to the latch sleeve via a core rod, the second return spring is disposed between the core rod and the latch sleeve, and the insertion end of the core rod is provided with a tapered surface. The tapered surface is used to self-adjust the table surface so that the upper surface of the table surface is flush with the upper surface of the support beam, thereby eliminating any gap between the table surface and the latch.

[0010] Preferably, the latch also includes a handle connected to the core rod, and the handle and the latch sleeve are each provided with tenons of identical structure but in opposite directions at their respective ends. When the latch is supported against the tabletop, the tenons of the latch and the latch sleeve overlap. When the latch is pulled out, the latch is rotated, and the tenons of the latch and the latch sleeve abut against each other, keeping the latch in the pulled-out position and preventing it from rebounding, thus making room for the tabletop to rotate.

[0011] Preferably, in order to improve the stability and support strength of the bracket, a cross brace is provided in the middle of the legs of the bracket.

[0012] Preferably, the legs of the bracket are retractable legs, and the legs are provided with knobs at the bottom, which can adjust the height to ensure that the four legs fit different ground surfaces and ensure the stability of the workbench.

[0013] Preferably, the legs comprise a plurality of connecting sections, each of which is uniformly provided with connecting holes. The legs can be secured by overlapping two connecting sections and then threading bolts and nuts through the connecting holes of the overlapping sections. Changing the length of the overlapping sections can adjust the height of the vertical legs, thereby achieving height adjustment of the platform.

[0014] Beneficial effects: Compared with the prior art, the utility model has the following advantages: 1. Easy to flip and high stability; 2. Support structures on both sides of the table; 3. Adjustable height; 4. Adjustable level. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solution of the present utility model will be further described below with reference to the accompanying drawings.

[0023] Example: Figures 1 to 5 As shown, the present invention discloses a reversible workbench. The workbench is primarily composed of a tabletop 1 and a bracket 2. A rotating shaft 11 is mounted at each end of the centerline of the tabletop 1. The tabletop 1 and the bracket top are rotatably connected via the rotating shaft 11. Rotating about the rotating shaft 11 allows the tabletop 11 to flip 180 degrees up and down. Tabletop fixing plates are provided at both ends of the tabletop, connecting the tabletop and the rotating shaft via the fixing plates. The bracket 2 is a frame structure 24, with a crossbeam 241 at the top, vertical legs 242 surrounding the bracket, and a cross brace 244 in the middle, connecting two adjacent legs 242.

[0024] like Figure 2 and 3 As shown, the bracket 2 is rotatably connected to the tabletop 1 via a crossbeam 241. The crossbeam 241 has an inverted U-shaped longitudinal cross-section. A transverse pin 21 and a pin sleeve 26 are mounted on one end of the crossbeam 241. The pin sleeve 26 is fixedly connected to the crossbeam 241. The pin 21 is mounted inside the pin sleeve 26, extending outward at the end closest to the tabletop. A return spring 22 is mounted on the other end, with both ends of the return spring 22 abutting against the bottom of the pin 21 and sleeve 26. When the tabletop 1 rotates, the pin 21 retracts into the pin sleeve 26. When the tabletop 1 returns to horizontal, the return spring 22 pushes the pin 21 back into place. The end of the pin 21 has a beveled surface 211, created by chopping off a corner of the pin 21. When the tabletop 1 is tilted below the pin, the bevel 211 allows the tabletop to push the pin 21 back into the crossbeam 241. When the tabletop 1 is horizontal, the spring pushes the pin 21 outward, with its top surface tangential to / parallel to the bottom of the tabletop, supporting the tabletop 1. When the longitudinal surface of the pin 21 is circular, a groove is defined in the middle of the pin 21, and a protruding stop pin 261 is mounted in the middle of the pin sleeve 26. When the pin 21 slides, the groove slides relative to the stop pin 261, which limits the sliding distance of the pin 21 and prevents the pin 21 from rotating, thus preventing the inclined surface 211 from changing position. The longitudinal surface of the pin 21 can also be polygonal. In this case, no additional device is required to prevent the pin 21 from rotating.

[0025] like Figure 4 and Figure 5As shown, the other end of the crossbeam 241 is equipped with a cross-threaded latch 23 and a latch sleeve 27. The latch sleeve 27 is fixedly connected to the crossbeam 241. The latch 23 is mounted within the latch sleeve 27 and extends from both ends of the latch sleeve 27. A return spring 28 is installed between the latch 23 and the latch sleeve 27. The latch 23 is inserted into the side wall of the table top or the support table 1 to lock the table top. Pulling the latch 23 outward unlocks the table top 1 and allows it to rotate relative to the bracket. In this solution, a support locking method is adopted, specifically: the pin 23 is mainly composed of a handle 232 and a core rod 231. The core rod 231 is installed inside the pin sleeve 27, and both ends extend out of the pin sleeve 27. The end away from the table is reduced in diameter and installed with the handle 232. The reduced diameter part forms a limit step for installing the reset spring 28; the end of the core rod 231 close to the table (the insertion end) is chamfered to form a conical surface. If the lower surface of the table contacts the conical surface, the pin 23 can continue to slide toward the table 1 under the push of the reset spring 28 until the cylindrical surface of its core rod 231 contacts the lower surface of the table. Through the conical surface, it self-adjusts to make the upper surface of the table flush with the upper surface of the beam 241. A tenon 271 is provided at one end of the latch sleeve 27 near the latch 23, and correspondingly, a tenon 2321 is provided at one end of the handle 232 near the latch sleeve 27. When the two tenons overlap up and down / front and back, the end of the core rod 231 of the latch extends to support the table top 1 and lock the table top; when the two tenons are collinearly abutted / partially abutted, the core rod 231 of the latch is pulled back to make space for the table top 1 to rotate; when the two tenons change from overlapping to abutting, the handle 232 is used to pull and rotate the latch 23.

[0026] The outrigger is a telescopic outrigger, mainly composed of several connecting sections. Figure 1 Two connecting sections are shown, namely the upper section 242 and the lower section 243. The longitudinal interfaces of both sections are L-shaped, and a number of connecting holes are evenly opened on the sides of the upper section 242 and the lower section 243. The upper section 242 and the lower section 243 are partially overlapped, and a bolt is passed through the connecting hole of the overlapping part and the nut is tightened to complete the connection between the upper section 242 and the lower section 243. By adjusting the length of the overlapping area between the upper section 242 and the lower section 243, the overall length of the leg can be adjusted, thereby adjusting the height of the table top 1. A knob 25 is provided at the bottom of the leg 1. The cap end of the knob 25 and the knob can be directly connected or connected with a universal ball. The knob 25 is used to fine-tune the table top to make it level. When connected with a universal ball, the leg can adapt to floors of different flatness.

[0027] When using, Figure 6 and Figure 7As shown, this is a schematic diagram of the use state of the utility model. The cutter 3 and the planer 4 are respectively fixed to the upper and lower sides of the table 1. When the cutter is needed, the cutter is located on the upper side. When the planer 4 is needed, the pin 23 is pulled outward and rotated, and one side of the table 1 is pressed down. The table is flipped 180° so that the planer 4 is located on the upper side. The pin 23 is rotated to release and fix the table for use.
