[0003] However, in the prior art, when the mineral casting bed of the CNC machining center is transported for shipment after processing, the mineral casting bed is easily cracked due to improper forklift transportation because the mineral casting bed is a mineral casting and the multiple forklift transportation directions at the bottom are all acute angles. Subsequent repair is very troublesome. At the same time, rectangular notches for subsequent screw and nut connection are opened on both sides of the existing mineral casting bed, which is convenient for subsequent installation of screw support feet at the bottom of the mineral casting bed. However, the rectangular notch is not designed with a sealing structure, resulting in the rectangular notch being exposed to the outside for a long time during later use. Foreign matter from the outside can easily enter the notch and cause unnecessary blockage or damage, affecting the subsequent normal adjustment and disassembly of the internal screw support feet. There are disadvantages. For this reason, the utility model proposes a mineral casting bed that can prevent forklift from cracking during transportation. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] See also Figures 1 to 4 , which is the first embodiment of the utility model, and provides a technical solution: a bed for preventing forklift-transported ore castings from collapsing, comprising

[0026] The bed 1 and the center notch 13 are provided at the center of the bottom of the bed 1, and the two side edges of the bottom of the bed 1 are provided with a 20mm chamfered surface 11, and the two end edges of the center notch 13 are provided with a 20mm chamfered surface 12. By chamfering from multiple forklift forklift directions, the bottom surface of the bed 1 can be effectively prevented from chipping during forklift transportation.

[0027] Rectangular notches 14 are provided on both sides of the bed 1, and screw holes 15 communicating with the rectangular notches 14 are provided on the bottom surface of the bed 1 for subsequent installation of screw support legs.

[0028] Both sides of the bed 1 are provided with a rotary blocking structure 2 corresponding to the rectangular notch 14, and the rotary blocking structure 2 includes a rectangular inner cavity 26 opened in the bed 1, a T-shaped inner slide 27 slidably mounted in the rectangular inner cavity 26, a cylindrical side rod 29 welded and fixed to the side of the T-shaped inner slide 27 and the end of which passes through the side of the bed 1, a circular end block 22 fixed to the end surface of the cylindrical side rod 29 and located on the outside of the bed 1, and a rotating sleeve on the end surface of the cylindrical side rod 29 and located between the circular end block 22 and the bed 1. The rotating seat 21 and the sealing plate 23 welded and fixed to the surface of one side of the rotating seat 21 can be rotated to cover the rectangular gap 14 in the later stage to achieve effective covering and blocking of the rectangular gap 14. The rotary blocking structure 2 also includes two return springs 28 arranged in the rectangular inner cavity 26. The two return springs 28 are located between the T-shaped inner slide seat 27 and the inner wall of the rectangular inner cavity 26. Under the pushing action of the return springs 28, the sealing plate 23 can subsequently stably cover the rectangular gap 14 to block the rectangular gap 14.

[0029] Among them, circular mounting grooves are opened on both end surfaces of the T-shaped inner slide 27, one end of the reset spring 28 is inserted into the circular mounting groove, and the other end of the reset spring 28 is against the inner wall of the rectangular inner cavity 26 to ensure the installation stability of the reset spring 28.

[0030] Among them, the rotary blocking structure 2 also includes a limit block 24 welded and fixed to the side of the sealing plate 23, and the side of the bed 1 relative to the top and bottom of the rectangular notch 14 is provided with a limit slot 25 corresponding to the limit block 24, so that when the sealing plate 23 is subsequently covered at the rectangular notch 14, the limit block 24 can be stuck in the limit slot 25 to ensure the stability of the sealing plate 23 itself. When the bed 1 completes the fork transportation and needs to install a screw support foot at its bottom, the screw end of the screw support foot can be inserted into the rectangular notch 14 through the screw socket 15, and then locked with a nut. Then the operator can pull the sealing plate 23 and the rotating seat 21 sideways with force, so that the rotating seat 21 moves sideways with the circular end block 22 and the cylindrical side rod 29, and the reset spring 28 is gradually compressed until the limit block 24 moves out of the limit card of the initial position. The groove 25 can rotate the rotating seat 21 and the sealing plate 23 one hundred and eighty degrees around the cylindrical side rod 29, so that the sealing plate 23 is aligned with the rectangular notch 14, and then the sealing plate 23 is gradually loosened, so that the return spring 28 pushes the T-shaped inner slide 27 back, and the cylindrical side rod 29 and the circular end block 22 pull the rotating seat 21 and the sealing plate 23 back, finally making the sealing plate 23 cover the rectangular notch 14, and making the limiting block 24 snap into another limiting groove 25, so that the sealing plate 23 can stably cover and block the rectangular notch 14, preventing foreign matter from entering the rectangular notch 14 during later use and causing unnecessary blockage and damage. When the screw support foot in the rectangular notch 14 needs to be adjusted later, it is only necessary to pull the sealing plate 23 sideways and rotate it away from the rectangular notch 14, which is very convenient to use.

[0031] Example 2

[0032] See also Figures 1 to 5 , which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment, but is different in that the circular rod hole 211 and the rubber seat 212 and other structures can play an auxiliary positioning role after the rotating seat 21 rotates, making it convenient for the operator to cover the sealing plate 23 on the rectangular notch 14.

[0033] Specifically, a circular rod hole 211 is provided on the surface of the rotating seat 21, and the circular rod hole 211 is adapted to the cylindrical side rod 29, so that the rotating seat 21 can be smoothly sleeved on the end of the cylindrical side rod 29, and the rotating seat 21 can rotate smoothly subsequently. A rubber seat 212 is embedded in the inner wall of the circular rod hole 211, and a positioning block 213 is provided on the surface of the rubber seat 212. Two positioning grooves 291 corresponding to the positioning block 213 are provided on the end surface of the cylindrical side rod 29. The end of the positioning block 213 is embedded in one of the positioning grooves 291, so that the rotating seat 21 can obtain a certain auxiliary limit after rotation. When the rotating seat 21 rotates subsequently, the end of the positioning block 213 will first The positioning groove 291 squeezed out of the initial position realizes the smooth rotation of the rotating seat 21 and the sealing plate 23. When the rotating seat 21 and the sealing plate 23 rotate smoothly one hundred and eighty degrees around the cylindrical side rod 29 and align the sealing plate 23 with the rectangular notch 14, the end of the positioning block 213 will be squeezed into another positioning groove 291, realizing the auxiliary positioning and limiting of the rotating seat 21 and the sealing plate 23 at this time. The rubber seat 212 and the positioning block 213 are an integrated structure. Both are made of rubber material and will undergo elastic deformation when squeezed. A semicircular notch corresponding to the position of the positioning block 213 is provided in the rubber seat 212, so that the positioning block 213 has sufficient deformation space when squeezed.

[0034] A rectangular embedding groove is formed on the inner wall of the circular rod hole 211 , and the rubber seat 212 is installed in the embedding groove so that the rubber seat 212 does not block the smooth rotation of the rotating seat 21 .

[0035] Although embodiments of the present invention have been shown and described (see the detailed description above for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
