Abstract
The utility model provides a two -way rotating screw, belongs to the machine parts field. Including the screw, the both ends of screw are rotatory end of forward and retrograde rotation end respectively, the rotatory end of forward is grooved countersunk head, its characterized in that be equipped with rotating assembly on the terminal surface of retrograde rotation end. Through the effective improvement to screw structure, one end at the screw sets up rotating assembly, more convenient when making the screw use in through -hole formula or open full thread hole, not only can make it fixed or screw out to the screw application of force through original countersunk head etc, still accessible rotating assembly realizes screwing out or fastening to carry out the application of force to the screw from the another party, feasible damage because of the screw leads to the condemned probability greatly reduced of corresponding spare part, make simultaneously operate at the operating space that receives the limitation more convenient, and a work efficiency is increased, simple structure, the easy to use, great market value has, and is suitable for popularization and use.
Description
Technical field
The utility model belongs to component of machine field, particularly relates to a kind of two-way rotating screw being applicable to passing hole type or open Full Thread FT hole.
Background technique
In field of machining, the machine used in machining process adds the cutter head of cutter, with alloy screw, blade is fixed on cutter head mostly, in use, due to the severe of work condition environment and frequent more allowing blade replacement, screw extraction, countersunk head wearing and tearing etc. are easily caused, thus screw cannot be taken off from cutter head, corresponding blade can not be changed, cause cutter head to be scrapped, cause waste.The structural design simultaneously adding jet blade due to machine limited, and when blade is fixed on cutter head by use screw, the special spanner used cannot be exerted all one's strength in screw countersunk head face, makes its operating efficiency and screw effect to be all restricted.
Summary of the invention
The utility model is intended to solve the problem, provide a kind of for passing hole type or open Full Thread FT hole, be simple and easy to two-wayly revolve screw.
Two-way rotating screw described in the utility model, comprises screw, and the two ends of screw are respectively and rotate forward end and counter-rotating end; Rotate forward the countersunk head of end for fluting; The end face of described counter-rotating end is provided with swivel assembly.Passing hole type or open Full Thread FT hole use reversible screw described in the utility model, screw rotate forward end because Environmental Conditions in peripheral structure restriction and cause operating inconvenience time, or when rotating forward end and damage because of frequent use, namely by the other end of bidirectional rotary formula screw, the swivel assembly of counter-rotating end carries out the knob of screw, thus reaches the object of back-out or fastening screw trip bolt.
Two-way rotating screw described in the utility model, described swivel assembly is a groove, uses and the screw-driver of groove match or instrument, is inserted in groove the reverse back-out or fastening realized two-way rotating screw.
Two-way rotating screw described in the utility model, described groove is crosswise, utilize the operation that cross or straight screwdriver can realize two-way rotating screw, the probability that the screw-driver of cross or a word uses in daily life is larger, obtaining than being easier to, groove being set to the use that crosswise is convenient in practice.
Two-way rotating screw described in the utility model, the centre of described groove establishes a cross section to be hexagonal groove, hexagonal groove is set, makes two-way rotating screw while use cross or straight screwdriver, inner hexagon spanner can also be used screw out or fastening two-way rotating screw.
Two-way rotating screw described in the utility model, described swivel assembly is a boss, utilizes to screw out two-way rotating screw with the socket wrench of boss mating shapes or fastening.
Two-way rotating screw described in the utility model, described boss cross section is Hexagon, to screw out or fastening with hexagonal socket wrench to it, and hexagonal socket wrench ratio is easier to obtain, boss is set to six prisms be for the ease of instrument be convenient to obtain, improve utilization efficiency.
Two-way rotating screw described in the utility model, by the effective improvement to bolt structure, in one end of screw, swivel assembly is set, it is more convenient when screw is used in passing hole type or open Full Thread FT hole, not only screw force can be made it fix or be screwed out by original countersunk head etc., also from other direction, force is carried out to screw by swivel assembly and realize back-out or fastening, the probability causing corresponding component to be scrapped because of the damage of screw is reduced greatly, to make to carry out in the operating space of being limited to operate more convenient simultaneously, improve working efficiency, and structure is simple, be easy to use, there is larger market value, be suitable for promoting the use of.
Accompanying drawing explanation
Fig. 1 is the structural representation of two-way rotating screw described in the utility model;
Fig. 2 is the worm's eye view of two-way rotating screw described in the utility model;
Wherein 1-rotates forward end; 2-counter-rotating end; 3-swivel assembly.
Embodiment
Two-way rotating screw described in the utility model, as shown in Figure 1, comprises screw, and the two ends of screw are respectively and rotate forward end 1 and counter-rotating end 2; Rotate forward the countersunk head that end 1 is fluting; The end face of described counter-rotating end 2 is provided with swivel assembly 3.Passing hole type or open Full Thread FT hole use reversible screw described in the utility model, screw rotate forward end 1 because in Environmental Conditions peripheral structure restriction and cause operating inconvenience time, or when rotating forward end 1 and damage because of frequent use, namely by the other end of bidirectional rotary formula screw, the swivel assembly 3 of counter-rotating end 2 carries out the knob of screw, thus reaches the object of back-out or fastening screw trip bolt.
Two-way rotating screw described in the utility model, described swivel assembly 3 is a groove, uses and the screw-driver of groove match or instrument, is inserted in groove the reverse back-out or fastening realized two-way rotating screw.
Two-way rotating screw described in the utility model, described groove is crosswise, utilize the operation that cross or straight screwdriver can realize two-way rotating screw, the probability that the screw-driver of cross or a word uses in daily life is larger, obtaining than being easier to, groove being set to the use that crosswise is convenient in practice.
Two-way rotating screw described in the utility model, as shown in Figure 2, the centre of described groove establishes a cross section to be hexagonal groove, hexagonal groove is set, make two-way rotating screw while use cross or straight screwdriver, can also use inner hexagon spanner to screw out or fastening two-way rotating screw, inner hexagon spanner is under the prerequisite reaching identical fastening effect, strength can be saved preferably, realize better fastening effect.
Two-way rotating screw described in the utility model, described swivel assembly 3 is a boss, utilizes to screw out two-way rotating screw with the socket wrench of boss mating shapes or fastening.
Two-way rotating screw described in the utility model, described boss cross section is Hexagon, to screw out or fastening with hexagonal socket wrench to it, and hexagonal socket wrench ratio is easier to obtain, boss is set to six prisms be for the ease of instrument be convenient to obtain, improve utilization efficiency.
During use, will the screw aligned through holes formula of swivel assembly 3 or open Full Thread FT hole be provided with, utilize instrument to rotate forward the countersunk head rotary screw of end 1 from screw, make it screw in or screw out tapped hole.In operating space the wearing and tearing of limited or screw countersunk head or screw because of force transition fracture time, utilize screw-driver or inner hexagon spanner or socket wrench, from the counter-rotating end 2 of screw, aim at swivel assembly 3 and is screwed out or fix, thus complete operation.
