Referring to fig. 1 and 2, a mold screw assembly according to an embodiment of the present utility model includes a fixing frame 100, a locking screw 102, an adjusting part 103, a drop-off preventing part 104 and a connection nut 105, wherein the fixing frame 100 is used for being mounted to one of two steel members 200 to be temporarily fixed, and screw mounting holes are coaxially provided in the fixing frame 100 corresponding to the mounting holes of the two steel members 200; the locking screw 102 is arranged in the screw mounting hole in a penetrating way and can be moved and adjusted along the axial direction of the screw mounting hole; the adjusting part 103 is arranged at one end of the locking screw 102 far away from the mounting hole; the anti-falling part 104 is arranged at the middle section of the locking screw 102 and is positioned at the other side of the fixing frame 100 relative to the adjusting part 103; the coupling nut 105 is fitted with a threaded section at the end of the locking screw 102. According to the die screw assembly, the locking screw 102 is fixed on one steel member 200 through the fixing frame 100, the locking screw 102 is prevented from falling off through the matching of the adjusting part 103 and the falling off preventing part 104, when temporary fixing is needed, the locking screw 102 can penetrate through the mounting holes of the two steel members 200, then the locking screw 102 is locked from the tail ends of the locking screw 102 through the connecting nuts 105, and the temporary fixing of the two steel members 200 is completed. Therefore, the die screw assembly can temporarily fix the traditional bolts on the steel member 200, and can be disassembled after the production is completed, so that the influence on the production efficiency caused by temporarily searching the bolts can be avoided.

Since the locking screw 102 is adjusted by the adjusting portion 103, for convenience of adjustment, in some embodiments of the present utility model, the adjusting portion 103 is provided with a wrench action portion 1032 and a hand-screwing action portion 1031, wherein the wrench action portion 1032 has a hexagonal prism structure coaxially disposed with the locking screw 102; the hand-screwing action portion 1031 is located at an end of the wrench action portion 1032 remote from the mount 100, and an outer peripheral dimension of the hand-screwing action portion 1031 is larger than that of the wrench. With the structural arrangement of this embodiment, an operator can first quickly move the locking screw 102 by screwing the action portion 1031 by hand and quickly pre-connect with the coupling nut 105 when temporarily fixed, and then lock by engaging the wrench with the wrench action portion 1032. In the process of disassembly, the unlocking is realized by matching the wrench with the wrench action part 1032, and then the locking screw 102 is rapidly separated and moved by manually rotating and dragging the hand-twisting action part 1031. And when using the spanner, can carry out the quick location of spanner through the manual action portion 1031, avoid the spanner slippage.

Specifically, in some embodiments of the present utility model, the hand-twisting action portion 1031 is provided with an adjusting wheel and a plurality of connecting rods, and the adjusting wheel is coaxially distributed with the locking screw 102; the connecting rod is provided between the adjustment wheel and the locking screw 102. By adopting the structural arrangement of the embodiment, when the locking screw 102 is manually rotated, the region between the two adjacent connecting rods and the adjusting wheel can be clamped by the finger for rapid rotation. And when the force is large and the single finger can not rotate quickly, the adjusting wheel can be held to rotate and move.

In some embodiments of the present utility model, the anti-slip portion 104 is an anti-slip nut mounted on the locking screw 102, and in order to secure the position of the anti-slip nut, the anti-slip nut is screwed to the end position of the threaded section of the end of the locking screw 102, so that the anti-slip nut is not loosened when the anti-slip nut and the connection nut 105 clamp the steel member 200. And the nut is adopted, the structure is simple, and the production cost is low. It is understood that the number of the anti-drop nuts can be flexibly set according to the needs.

In practice, after the coupling nut 105 is removed to separate the two steel members 200, the coupling nut 105 may be reinstalled on the locking screw 102 to avoid loss. The coupling nut 105 may also be welded to another steel member 200.

In some embodiments of the present utility model, the fixing frame 100 is provided with a bottom plate and side plates vertically provided at both ends of the bottom plate, and the side plates at both ends are parallel to each other, and screw mounting holes are formed in the side plates. And the bottom four vertex positions of the bottom plate are provided with struts, and the bottoms of the struts are welded on the steel member 200. By adopting the structural arrangement of the embodiment, the locking screw 102 is penetrated through the two side plates, so that the mounting stability of the locking screw 102 and the coaxiality with the mounting hole can be ensured. And welded to the steel member 200 using the stay, the cutting is conveniently performed after the production is completed. And then welding again.

Considering that the locking screw 102 is easily moved while not being temporarily fixed, noise is caused, and bending deformation of the locking screw 102 may be caused, for this reason, in some embodiments of the present utility model, a rubber pad 101 is provided between both side plates, and screw mounting holes pass through the rubber pad 101 at the same time. Thus, when the locking screw 102 passes through the screw mounting hole, the locking screw 102 can be relatively fixed by the friction force of the rubber pad 101, so that the locking screw 102 is prevented from moving.

Referring to fig. 1 and 2, it can be understood that the distance between the adjusting portion 103 and the falling off preventing portion 104 satisfies that the locking screw 102 is completely withdrawn from the mounting hole of the steel member 200 when the falling off preventing portion 104 abuts against the fixing frame 100. The distance between the adjusting part 103 and the anti-falling part 104 satisfies that the connecting nut 105 and the anti-falling part 104 are matched to clamp the two steel members 200, and meanwhile, the distance between the adjusting part 103 and the fixing frame 100 is still reserved.

The present utility model has been described in detail with reference to the embodiments, but the present utility model is not limited to the embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model.
