DETAILED DESCRIPTION

[0029] In order to more intuitively and completely understand the technical solution of the present invention, a non-limiting feature description is now provided in conjunction with the accompanying drawings of the present invention as follows:

[0030] Embodiment 1: Figure 1 — Figure 7 As shown, a multifunctional workbench comprises a workbench 1 and a bracket 2 arranged at the bottom of the workbench 1. The top of the workbench 1 has a U-shaped groove 1.1 with an opening upward, which can be used to install a fixture (not shown in the figure). A bearing seat 3 is hinged on both sides of the upper end of the bracket 2. A bearing 4 is arranged in the bearing seat 3. A guide rod 5 is fixed on both sides of the bottom of the workbench 1. The guide rod 5 passes through the bearing 4 and slides with the bearing 4; the bracket 2 includes a front support leg 21 and a rear support leg 22 which are hinged to each other at the upper end. The support leg 21 and the rear support leg 22 are both rectangular parallelepiped. A front support rod 6 is provided between the front support foot 21 and the bottom of the front end of the workbench 1, and a rear support rod 7 is provided between the rear support foot 22 and the bottom of the rear end of the workbench 1. The front support rod 6 and the rear support rod 7 are both U-shaped. The two ends of the front support rod 6 are respectively hinged to the front support foot 21 and the workbench 1. One end of the rear support rod 7 is hinged to the rear support foot 22, and the other end is detachably connected to the workbench 1. The front support foot 21 and the rear support foot 22 are respectively provided with a front receiving groove 211 and a rear receiving groove 221 for accommodating the front support rod 6 and the rear support rod 7. The rear end of the guide rod 5 is fixed to the rear end of the workbench 1, and the front end of the guide rod 5 extends to the middle of the workbench 1. The workbench 1 can rotate with the rotation of the bearing seat 3 during the movement.

[0031] In order to facilitate the disassembly and assembly of the rear support rod 7, two clamping platforms 8 are provided at the bottom of the rear end of the workbench 1. The clamping platforms 8 have a clamping slot 81 opening downward, and the other end of the rear support rod 7 is clamped into the clamping slot 81. The outer end of the clamping platform 8 has an elastic key board 82, which blocks the rear end of the rear support rod 7. The rear end of the key board 82 is hinged to the bottom of the workbench 1, and a spring (not shown in the figure) is provided between the front end and the workbench 1. When the front end of the key board 82 is pressed upward, the rear support rod 7 is freed from the restraint of the key board 82, so that it can be pulled down.

[0032] An openable or foldable storage board 9 is provided between the middle of the front support leg 21 and the rear support leg 22. The storage board 9 includes two mutually hinged placement boards 91, one end of each placement board 91 being respectively hinged to the front support leg 21 and the rear support leg 22. When the multifunctional work frame is in a fully open or semi-folded state, things can be placed on the storage board 9; when the multifunctional work frame needs to be completely folded, the two placement boards 91 need to be folded and folded.

[0033] The workbench 1 is provided with a locking mechanism to prevent the workbench 1 from sliding, and the locking mechanism includes a cam knob 10 arranged at the upper end of the workbench 1, a cam shaft 11 connected to the lower end of the cam knob 10, a cam plate 12 fixed to the lower end of the cam shaft 11, a pair of connecting rods 13 hinged at the front and rear ends of the cam plate 12, and a pair of locking plates 14 hinged at the ends of the two connecting rods 13 and used to block the bearing seat 3. The two connecting rods 13 are distributed on the left and right sides, and the two locking plates 14 are respectively hinged on the left and right sides of the bottom of the workbench 1. The outer sides of the two locking plates 14 are provided with grooves 141 for the corresponding bearing seats 3 to be inserted, and the grooves 141 are provided to facilitate the locking plates 14 to contact the bearing seat 3. The locking mechanism can prevent people's operating errors and prevent the workbench 1 from sliding at will when operating errors occur.

[0034] The locking mechanism is used as follows: when unlocking, stand at the rear end of the workbench 1 and turn the cam knob 10 clockwise by hand. The cam knob 10 drives the cam plate 12 to rotate through the cam shaft 11. The cam plate 12 drives the two connecting rods 13 to move inward, so that the locking piece 14 is away from the bearing seat 3. At this time, the workbench 1 will not be restricted by the bearing seat 3 and can slide through the guide rod 5; when the workbench 1 is to be locked with the locking mechanism, turn the cam knob 10 counterclockwise, and the locking piece 14 will approach the bearing seat 3. When the workbench 1 moves, the bearing seat 3 will block the locking piece 14, so that the workbench 1 cannot slide.

[0035] In order not to affect the placing of objects on the workbench 1 , a placement groove 15 with an opening facing upward is provided at the middle position of the upper end of the workbench 1 , and the cam knob 10 is accommodated in the placement groove 15 .

[0036] like Figure 4As shown, the middle of the end of the rear support rod 7 connected to the workbench 1 has a protruding fixing rod 71, and the middle of the end of the front support rod 6 hinged to the workbench 1 is hinged with a locking handle 16 with a fixing groove 161, and the fixing groove 161 is for the fixing rod 71 to be inserted. When the multifunctional work frame is completely folded, the fixing rod 71 of the rear support rod 7 is inserted into the fixing groove 161 of the locking handle 16, and then the multifunctional work frame can be erected and placed on the ground without being loose.

[0037] Figure 1 The multifunctional workbench in the state is used as the main working state, such as for woodworking to process wood. When the multifunctional workbench needs to be moved from Figure 1 The usage status is switched to Figure 5 When the workbench 1 is in use, the rear support rod 7 is first pulled down, the locking mechanism is unlocked, and then the workbench 1 is pushed. The workbench 1 can fit with the front support leg 21 through gravity and the setting of the guide rod 5 and the bearing seat 3, thereby obtaining Figure 5 In the state of use, the workbench 1 is in a tilted state; when the multifunctional workbench needs to be moved from Figure 5 The usage status is switched to Figure 6 When the storage board 9 is in the use state, the storage board 9 is folded and folded, and then the rear support leg 22 is rotated to close the rear support leg 22 and the front support leg 21, so as to obtain Figure 6 usage status.

[0038] Embodiment 2: Figure 8 and Fig. 9 As shown, the difference between the second embodiment and the first embodiment is that: a push rod 17 is installed at the rear end of the workbench 1; two fixed wheels 19 are provided at the lower end of the outer side of the rear supporting foot 22, and two universal wheels 18 are provided at the upper end. After the multifunctional workbench is folded, the fixed wheels 19 and the universal wheels 18 touch the ground, and the push rod 17 can play the role of a "trolley" when held by hand. The push rod 17 can be installed in a plug-in manner and fixed with a lock 20 after installation, that is, the push rod 17 can be removed. A plurality of clips 30 and sockets (not shown) are provided on the outer side of the rear supporting foot 22. The middle portion 7 of the push rod 1 can be clamped on the clip 30, and the latch 40 at the end of the push rod 1 is inserted into the socket, thereby obtaining Fig. 9 state, convenient for storage.

[0039] Of course, the above are only preferred embodiments of the present invention, and the patent scope of the present invention is not limited thereto. All simple modifications and equivalent structural changes made using the contents of the specification and drawings of the present invention should be included in the patent protection scope of the present invention.
