Abstract
The utility model discloses a screw which comprises two screws and a fixing block, wherein surfaces of the screws are provided with threads, and one ends of the screws are pointed ends. The fixing block is of a regular hexagonal prism; the two screws are respectively vertically fixed on two bottom surfaces of the fixing block; the pointed ends of the screws face outwards, and the center lines of the two screws are in a same straight line with the center line of the fixing block. The screws can fix two thick wood boards without penetrating through the wood boards.
Description
Technical field
The utility model relates to a kind of threaded fastener, relates in particular to a kind of screw.
Background technique
At the furniture machining center, fixing by screw between a lot of wooden unit parts.Common screw, such as notice of authorization CN202431715U, on September 12 2012 notice of authorization day, patent name is screw, comprises with screw head, screw rod and is arranged on the drill bit of screw head, it is characterized in that: described screw rod outside offers screw thread.When utilizing above-mentioned screw to fix two planks, screw often needs to run through a plank, inserts another piece plank again and fixes.But, when two planks are all thicker, will exist screw to be difficult for running through plank, perhaps run through few, the fixing illusive problem of residue screw length behind the plank.
Summary of the invention
The utility model is in order to address the above problem, and proposes a kind ofly to need not to run through plank and just can fix two than the screw of thick plank.
To achieve these goals, the utility model is by the following technical solutions: a kind of screw, comprise that two surfaces are provided with screw thread, an end is most advanced and sophisticated screw rod and a fixed block, described fixed block is positive six prisms, two screw rods are vertically fixed on respectively on two bottom surfaces of fixed block, the tip of screw rod toward the outer side, the center line of the center line of two screw rods and positive six prismatic fixed blocks is located along the same line.
As preferably, described two screw flights oppositely arrange.
Therefore, the utlity model has following beneficial effect: (1) need not to run through plank and fixes, and is easy to use; (2) technique is simple, and is easy to process; (3) simple in structure, cost is low.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
1: screw rod; 2: fixed block.
Embodiment
Below in conjunction with accompanying drawing and specific embodiments the utility model is further described.
A kind of screw, referring to Fig. 1, comprise that two surfaces are provided with screw thread, an end is most advanced and sophisticated screw rod 1 and a fixed block 2, described fixed block 2 is positive six prisms, two screw rods 1 are vertically fixed on respectively on two bottom surfaces of fixed block 2, the tip of screw rod 1 toward the outer side, the center line of the center line of two screw rods 1 and positive six prismatic fixed blocks 2 is located along the same line, the screw thread of described two screw rods 1 oppositely arranges.
During use, first screw is put between two planks, with just hand steered, so that screw keeps substantially vertical with the plank surface, choose again the spanner that mates with positive six prismatic fixed blocks 2 and be stuck on the fixed block 2 of screw, screw in plank direction rotation spanner toward hypomere screw rod 1, because the screw thread of two screw rods 1 oppositely arranges up and down, so that during rotary spanner, two screw rods 1 are all the plank state that screws in up and down.Therefore, only need rotary spanner, up and down two screw rods 1 of screw can be screwed in respectively in two planks, thereby fixing plank need not to run through plank.
Claims (2)
1. screw, it is characterized in that: comprise that two surfaces are provided with screw thread, an end is most advanced and sophisticated screw rod (1) and a fixed block (2), described fixed block (2) is positive six prisms, two screw rods (1) are vertically fixed on respectively on two bottom surfaces of fixed block (2), the tip of screw rod (1) toward the outer side, the center line of the center line of two screw rods (1) and positive six prismatic fixed blocks (2) is located along the same line.
