[0025] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0026] See also Figure 1-6The utility model provides an embodiment: a high-strength folding workbench, including a main table and a support frame 12 at the bottom. The main table is composed of two table boards 10 that can be flipped and folded. The bottom ends of the two table boards 10 are connected by four rotating hinges 18 installed at equal intervals, so that they can be folded. The cross bar at the top of the support frame 12 is rotatably installed between the front and rear side walls of the inner cavity at the bottom of the table board 10. A cross bar 13 is fixedly connected between the two support bars of the support frame 12. The end surfaces of the two table boards 10 that are close to each other are respectively provided with fan-shaped grooves 20. An interlocking plate 15 is slidably installed in the inner cavity at the bottom of each table board 10. Each of the interlocking plates 15 is respectively provided with an extension part 1501. Each of the extension parts 1501 slide through the corresponding fan-shaped groove 20 respectively, one of the extensions 1501 on the left and right sides is provided with a stepped concave surface on the upper end surface, and the other is provided with a corresponding stepped concave surface on the lower end surface, and the two can fit each other, and each of the interlocking plates 15 is fixedly installed with an L-shaped connecting plate 16 at the bottom end, and a supporting diagonal rod 14 is connected between the cross piece 13 and the L-shaped connecting plate 16, one end of the supporting diagonal rod 14 is hinged to the L-shaped connecting plate 16, and the other end is detachably installed on the cross piece 13. It should be noted that the detachable structure is that the bottom end of the upper supporting diagonal rod 14 is fixedly connected with a buckle block 19, and a fan-shaped groove 20 is provided at the center position of the cross piece 13, and the buckle block 19 is slidably embedded in the fan-shaped groove 20;

[0027] Therefore, when it is needed, the table top 10 is first opened, and then the two support frames 12 are rotated to be vertical for support, and then the two interlocking plates 15 are pushed towards each other, so that the stepped concave surfaces on the two interlocking plates 15 fit together to form a locking shape, so that the stability and supporting strength of the main table after unfolding can be greatly improved, especially at the connection between the two table tops 10, which can effectively prevent the collapse of the middle folding connection when the work table is subjected to excessive force, and then the snap block 19 is inserted into the fan-shaped groove 20 to fix it.

[0028] It is worth mentioning that in order to improve the stability of the interlocking plate 15, in the present embodiment, horizontal bar protrusions 17 are respectively provided on the front and rear side walls of the inner cavity of the above-mentioned table top 10, and right-angle grooves 1503 are respectively provided at the bottom of the two side edges of the interlocking plate 15, and each of the horizontal bar protrusions 17 is respectively embedded in the corresponding right-angle groove 1503, so that the two sides of the interlocking plate 15 can slide along the horizontal bar protrusions 17.

[0029] In addition, in one embodiment, circular hole grooves 22 are respectively provided on both sides of the through cavity 21 in the table top 10, and circular hole grooves 1502 are respectively provided on both sides of the extension part 1501 in the interlocking plate 15, and a spring is installed between the circular hole groove 1502 and the circular hole groove 22 to increase the elastic force of the spring, so that when the interlocking plate 15 is squeezed and slid inward, the interlocking plate 15 will have an outward thrust, which can be transmitted to the supporting diagonal rod 14, so that the contact between the snap block 19 and the fan-shaped groove 20 is more stable. At the same time, when the workbench table is stored, the interlocking plate 15 can be automatically popped out by sliding the snap block 19 out of the fan-shaped groove 20.

[0030] In addition, in one embodiment, a handle groove 11 is provided at the outer edge of each of the table tops 10, and a rubber pad is provided in each of the handle grooves 11, so that the workbench table can be folded conveniently by grasping the handle groove 11 with hands. At the same time, rubber protective covers are respectively provided at the bottom of the two support rods of the support frame 12 to increase the friction between the support frame 12 and the ground.

[0031] During the specific implementation, the table top 10 is first opened, and then the two support frames 12 are rotated to be vertical for support, and then the two interlocking plates 15 are pushed towards each other, so that the stepped concave surfaces on the two interlocking plates 15 fit together to form a locking shape, so that the stability and supporting strength of the main table after unfolding can be greatly improved, especially at the connection between the two table tops 10, which can effectively prevent the collapse of the folding connection in the middle when the work table is subjected to excessive force, and then the snap block 19 is inserted into the fan-shaped groove 20 to fix it. When it needs to be stored, the snap block 19 is pulled out of the fan-shaped groove 20, and the interlocking plates 15 will pop out of each other, so that the two stepped concave surfaces are out of contact, so that the table top 10 can be folded.

[0032] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
