The utility model discloses when twisting the screw, need not embolia jie's piece in addition, it is not only convenient, very firm in addition, the pawl can block the metal sheet, and is when external force such as receive vibrations, pull influences, difficult not hard up, the threaded rod is difficult for appearing the deviation when twisting the screw to the concave surface of tongue shape recess can form sharp cutting edge with the intersection of threaded rod lateral surface, and messenger's screw can cut the burr that falls in the screw at the in -process of wrong income metal sheet screw, thus smooth wrong income screw.
Description
Technical field
This utility model relates to screw technical field, particularly to a kind of metallic plate connecting screw.
Background technology
Screw is to utilize the inclined-plane circular rotating of object and the physics of frictional force and mathematical principle, fastens the part of implements parts by easy stages, and application is widely.The installation of metallic plate connects generally also to be needed to use screw, in the prior art, metallic plate connecting screw generally includes interconnective nut and screw rod, but, existing metallic plate connecting screw is in use, often there is following disappearance: one, screw, after tightening, when being affected by external force such as shaking, pull, easily loosen；Two, screw is when being screwed into screw, and deviation easily occurs in para-position；Three, inside the screw of metallic plate, metallic bur power often occurs, make screw be difficult to be screwed into.
Utility model content
The technical problems to be solved in the utility model is according to above-mentioned the deficiencies in the prior art, it is provided that one is tightened and is difficult to afterwards loosen, and is difficult to deviation occur when being screwed into, and is prevented from the metallic plate connecting screw that the impact of screw burr is screwed into.
For solving above-mentioned technical problem, the technical solution of the utility model is: a kind of metallic plate connecting screw, be fixedly connected sequentially nut, Jie's sheet and threaded rod from left to right, given an account of sheet right side is provided with some pawls, offering three equally distributed tongue shape grooves outside described threaded rod right part, the length direction of this tongue shape groove is consistent with the length direction of threaded rod.
It is expanded on further as to of the present utility model:
Described nut is hexagonal (hexagon)nut, and the left side of hexagonal (hexagon)nut is provided with a counterbore；Given an account of sheet right side is provided with 18 pawls.
A length of 4.3mm～4.7mm of described nut, opposite side distance is 10.8mm～11.2mm；The thickness of given an account of sheet is 1.2mm～1.4mm, a diameter of 14.3mm～14.7mm, and the pawl degree of depth is 0.3-0.4mm；A length of 22.7mm～23.3mm of described threaded rod, tooth footpath is 6.79mm～6.97mm；A length of 5.0mm～6.0mm of described tongue shape groove, left end width is 1.6mm～2.0mm, and right-hand member width is 3.0mm～3.4mm.
Described metallic plate connecting screw is the iron metal plate connecting screw of global formation, and its surface is coated with one layer of phosphating coat.
The beneficial effects of the utility model are: one, be fixedly connected sequentially, when being screwed into screw due to nut, Jie's sheet and threaded rod, it is not necessary to will additionally be inserted in Jie's sheet, not only facilitate, and the most firm；Two, it is provided with some pawls, therefore, when tightening screw due to Jie's sheet right side, pawl can block metallic plate, when the external force such as being given a shock, pull and affecting, is difficult to loosen, if additionally, arrange the lines being engaged mutually with pawl on metal plate, then screw can be made to be more difficult to loosen；Three, owing to offering three equally distributed tongue shape grooves outside threaded rod right part, the length direction of this tongue shape groove is consistent with the length direction of threaded rod, therefore, the right part of threaded rod is difficult to deviation occur when being screwed into screw, further, the concave surface of tongue shape groove can form sharp-cutting edge with the intersection of threaded rod lateral surface, makes screw during being screwed into metallic plate screw, the burr in screw can be machined away, thus be screwed into screw smoothly.

Detailed description of the invention
Below in conjunction with the accompanying drawings structural principle of the present utility model and operation principle are described in further detail.
As shown in Figure 1-Figure 3, this utility model is a kind of metallic plate connecting screw, it is adaptable to the metallic plates such as furniture metallic plate, electric equipment metallic plate connect fixed mechanism.This metallic plate connecting screw has been fixedly connected sequentially nut 1, Jie's sheet 2 and threaded rod 3 from left to right, given an account of sheet 2 right side is provided with some pawls 21, offering three equally distributed tongue shape grooves 4 outside described threaded rod 3 right part, the length direction of this tongue shape groove 4 is consistent with the length direction of threaded rod 3.This utility model is when being screwed into the screw (not shown) of metallic plate, owing to offering three equally distributed tongue shape grooves 4 outside threaded rod 3 right part, threaded rod 3 is made to be difficult to that deviation occurs, and, the concave surface of tongue shape groove 4 can form sharp-cutting edge 5 with the intersection of threaded rod 3 lateral surface, make screw during being screwed into metallic plate screw, the burr in screw can be machined away, thus best hand is screwed into screw.
As depicted in figs. 1 and 2, described nut 1 is hexagonal (hexagon)nut 1, and the left side of hexagonal (hexagon)nut 1 is provided with a counterbore 11；Given an account of sheet 2 right side is provided with 18 pawls 21, is so conducive to tightening screw.
As shown in Figure 1-Figure 3, length L1 of described nut 1 is 4.3mm～4.7mm, preferably 4.5mm, and opposite side distance D1 is 10.8mm～11.2mm, preferably 11mm；The thickness L2 of given an account of sheet 2 is 1.2mm～1.4mm, preferably 1.3mm, and diameter 1 is 14.3mm～14.7mm, preferably 14.5mm, and pawl 21 depth H is 0.3-0.4mm, preferably 0.35mm；Length L3 of described threaded rod 3 is 22.7mm～23.3mm, preferably 23mm, and tooth footpath 2 is 6.79mm～6.97mm, preferably 6.84mm～6.88mm；Length L4 of described tongue shape groove 4 is 5.0mm～6.0mm, preferably 5.5mm, and left end width D 2 is 1.6mm～2.0mm, preferably 1.8mm, and right-hand member width D 3 is 3.0mm～3.4mm, preferably 3.2mm.Using the nut 1 of this specification, Jie's sheet 2 and threaded rod 3, its global shape size is unified, can meet the fixing bonding strength of metallic plate, can keep again less size, the connection secure fit degree of metallic plate finally can be made to reach optimal.
In technique scheme, described metallic plate connecting screw is the iron metal plate connecting screw of global formation, and its surface is coated with one layer of antioxidation, corrosion resistant phosphating coat.So overall can save processing cost, material cost and metallic plate property easy to connect, and the bulk strength of metallic plate connecting screw is greatly improved.
