The sliding block 11 can rotate around the hinge axis between itself and the locking block 21, i.e., the slider shaft 13, to adapt to different installation and fixing positions of the workpiece.

[0049] To accommodate the installation and fixing of different workpieces, the sliding block 11 is also equipped with a mating structure for engaging with the fixing structure on the workpiece. Figure 8 As shown in the example, the sliding block 11 is also provided with an insert 14 and a protrusion 15; the sliding block shaft hole 12 is provided on the protrusion 15. The insert 14 can be inserted into the insert groove on the workpiece and slide back and forth to adapt to different installation and fixing positions. In order to enhance the connection and fixing effect, screw holes 141 are also provided on both sides of the insert 14, and spring plungers or ball screws 142 are provided in the screw holes 141.

[0050] In the embodiments of this application, workpiece connecting mechanism 1 with other structures can also be used to adapt to the installation and fixing of different workpieces.

[0051] The workbench locking mechanism 2 includes a locking block 21, a movable locking ring 22, an unlocking button 23, a rotating locking bar 25, and an elastic component 26.

[0052] The locking block 21 includes a bottom block 215 and a top block 216. The bottom block 215 is fastened to the top block 216 as a single unit by a snap-fit ​​connection and / or screw connection, and has an opening for the movable locking ring 22 to extend into and lock. The locking block 21 has a receiving groove 211, and a retaining bar pivot hole 212 is provided on the bottom of the receiving groove 211. The receiving groove 211, the retaining bar pivot hole 212, and the button rod hole 213 can be provided on the bottom block 215 and / or the top block 216.

[0053] The rotating locking bar 25 has an elongated structure, on which a locking bar pivot 251, a locking connector 252, and a button mating part 253 are provided; the locking connector 252 and the button mating part 253 are respectively located on both sides of the locking bar pivot 251; the rotating locking bar 25 is located in the receiving groove 211, and the locking bar pivot 251 is rotatably located in the locking bar pivot hole 212 of the locking block 21. The rotating locking bar 25 can rotate clockwise or counterclockwise around the locking bar pivot 251 to lock or unlock.

[0054] The locking block 21 is also provided with a button rod hole 213 and a button limiting hole 214; the button rod hole 213 is connected to the receiving groove 211, and the button limiting hole 214 is connected to the button rod hole 213 and its axis is perpendicular to the axis of the button rod hole 213.

[0055] The unlocking button 23 includes a button body 231, a button rod 232, and a limiting groove 233. The button groove 233 is disposed on the button rod 232 and its diameter is smaller than that of the button rod 232. The button rod 232 is disposed within the button rod hole 213 and its end extends into the receiving groove 211 to cooperate with the button mating part 253 of the rotating retaining strip 25. A button limiting component 24 is disposed within the button limiting hole 214. The end of the button limiting component 24 extends into the limiting groove 233. The button limiting component 24 can be various common fasteners such as nut screws.

[0056] One end of the elastic member 26 abuts against the button mating part 253 (specifically, the side of the button mating part 253 opposite to the unlock button 23), and the other end of the elastic member 26 abuts against the groove of the receiving groove 211. To improve the stability of the connection of the elastic member 26, corresponding portions of the button mating part 253 and the groove of the receiving groove 211 are also provided with elastic member mounting grooves. Both ends of the elastic member 26 are respectively set in the corresponding elastic member mounting grooves. The elastic member 26 can be a spring or a spring sheet.

[0057] Therefore, during the process of the unlock button 23 being pressed and causing the end of the button rod 232 to extend into the receiving groove 211 and act on the button mating part 253, and during the process of the unlock button 23 being released and rebounding back to its original position under the action of the elastic member 26, the extension and retraction space of the unlock button 23 is limited within the stroke determined by the button limiting member 24 and the limiting groove 233, so that the unlock button 23 cannot extend excessively into the receiving groove 211 or disengage from the locking block 21.

[0058] The rotating locking bar 25 can rotate around the locking bar pivot 251 within the receiving groove 211, thereby enabling locking and unlocking through the cooperation of the locking head 252 and the corresponding structure (locking ring locking head 221) on the movable locking ring 22; pressing the unlocking button 23 can drive the rotating locking bar 25 to rotate for unlocking through the button engagement part 253; releasing the unlocking button 23 allows the rotating locking bar 25 to rotate in the opposite direction and reset to the locking state under the action of the elastic member 26; at the same time, the unlocking button 23 will be popped back to the pressing unlocking state by the button engagement part 253.

[0059] The locking block 21 is provided with a locking ring engagement structure 217; both the locking ring engagement structure 217 and the movable locking ring 22 are provided with locking ring shaft holes; the movable locking ring 22 is hinged to the locking ring engagement structure 217 through the engagement of the locking ring shaft 27 and the locking ring shaft holes of both sides.

[0060] After locking, the locking ring mating structure 217 and the movable locking ring 22 can form a locking structure that matches the positioning post of the worktable, such as a cylindrical locking structure or a prism locking structure. In this embodiment, the middle locking structure is a cylindrical locking structure.

[0061] The movable locking ring 22 is provided with a locking ring head 221; the locking ring head 221 and the locking head 252 on the rotating locking bar 25 have the same structure, both including a hook head 222 and a hook head groove 223.

[0062] Rotating the movable locking ring 22 allows the locking ring head 221 on the movable locking ring 22 to contact the locking head 252 on the rotating locking bar 25, causing the hooks 221 of both sides to be embedded in the hook grooves 223 of the other side to achieve locking; pressing the unlocking button 23 causes the locking head 252 on the rotating locking bar 25 to rise in the unhooking direction to unlock; after the locking ring head 221 on the movable locking ring 22 rotates away from the locking head 252 on the rotating locking bar 25, releasing the unlocking button 23 causes the rotating locking bar 25 to rotate back to its original position under the action of the elastic component 26.

[0063] Implementation principle and technical effects:

[0064] In the workpiece connection step, the protrusion 15 on the sliding block 11 is embedded into the fixing structure 40 (i.e., the embedding groove) on the workpiece 20 and slid along the extension direction of the groove to a suitable position.

[0065] In the locking process, rotate the movable locking ring 22, causing the locking ring head 221 to rotate around the worktable positioning post 30 and contact the locking connector 252 on the rotating locking strip 25, so that the hooks 221 of both sides are respectively embedded into the hook grooves 223 of the other to complete the locking; the state at this time is as follows Figure 5 As shown;

[0066] To unlock, press the unlock button 23, causing the button lever 232 to push the rotating locking bar 25 to rotate. The locking connector 252 on the rotating locking bar 25 will then lift in the disengagement direction to unlock; the state at this time is as follows: Figure 6 As shown;

[0067] To return the button to its original position, rotate the movable locking ring 22 in the unlocking direction; release the unlock button 23, and the rotating retaining bar 25 will rotate in the opposite direction and return to its original position under the action of the elastic component 26; at the same time, the unlock button 23 will be lifted back to its original position by the button engagement part 253 of the rotating retaining bar 25 and ready to be pressed to unlock; at this time, the state is as follows Figure 7 As shown.

[0068] Therefore, the woodworking positioning block disclosed in this application can quickly lock the workpiece onto the worktable by rotating the movable locking ring 22, and can also quickly unlock by pressing the unlock button 23 and rotating the movable locking ring 22, which has the technical effects of being easy to use and having a reliable connection.

[0069] The technical solutions and effects of this application have been described in detail above with reference to the accompanying drawings and specific embodiments. It should be noted that those skilled in the art can develop other implementation methods based on this.
