Description

Structurally improved screw belt

The utility model relates to a kind of fastening piece, refer to especially a kind of ring set is designed to triangle, and make it have splendid ductility and covering property, and then when wearing screw, ring set can firmly coat, the structurally improved screw belt of supporting screw.

Please consult Fig. 1 simultaneously, 2,3, it is that screw belt is through constantly improvement, after the innovation, institute presents various structure form, though and each screw belt has separately design theory and advantage, but its structure all is to be provided with some bearing hole B that can ccontaining screw head on a body A, and extend a ring set C in the lower edge of this bearing hole B, and be provided with some slotted eye D that run through in the appropriate location of bearing hole B, this runs through slotted eye D and extends to ring set C and leave a suitable spacing with its bottom, again, the ring set C of above-mentioned Screw band screws togather operation for screw can be worn out easily, so make the ring wall of ring set C be designed to thin shape, and, but for making its supporting screw neck, make screw have a suitable angle, so it is all that ring set C shaped design is circular, the neck of screw is tightly coated, and the diameter of this ring set C is equal to or slightly less than the diameter of screw neck at least, can reaches the effect of coating.Though the ring set C of above-mentioned screw belt has the screw of coating neck, and form the angle of a supporting screw, yet when drift bolt operation and actual the use, still have following shortcoming:

1, please consult shown in Fig. 4,5,6 simultaneously, when nailing maching wears screw to bearing hole B and ring set C the time, though this nailing maching has a fixing propelling movement stroke through setting, but unavoidable small gap, the distance generation error (longer slightly) that screw is pushed of taking place in machinery action than the distance that sets; Again, nailing maching is when wearing screw, and the center line concentricity of its screw and ring set C must be same straight line, and when being placed through nonconcentric(al) screw in the ring set C with the nailing maching brute force, this ring set C must bear the strength that screw expands outwardly.Owing to ring set C be designed to thin-walled and closely coat screw do not have any nargin, so improper strength that when ring set C bears above-mentioned installing screw, is produced, this ring set C can or run through slotted eye D because of distortion and suffer oppression to produce and break, and make ring set C can't closely coat supporting screw, make screw present the state of deflection, and then influence the normal use of nailing maching.

2, for making screw when locking object, can break away from screw belt, this ring set C is provided with some slotted eye D that run through, so that screw makes it that ring set C impact extrusion is broken by the spinning strength of nailing maching, and then break away from screw belt, yet, because this ring set C is rounded, and the spinning strength that makes nailing maching is evenly distributed on the circumference of ring set C, so when the screw head shear spinning, often make the fracture of ring set C and body A joint, and depend on the screw neck, the shortcoming that causes screw to screw togather.

The purpose of this utility model promptly is to improve the above-mentioned shortcoming of commonly using the screw belt existence, and provide a kind of structurally improved screw belt, so that its ring set is designed to triangle, and make it have splendid ductility and covering property, and then when wearing screw, make ring set can play the effect of coating, supporting screw firmly.

For this reason, the utility model is taked following technological scheme:

A kind of structurally improved screw belt, it is to be provided with some bearing holes that can ccontaining screw head on a body, and the lower edge in this bearing hole extends a ring set, and be provided with some slotted eyes that run through in the appropriate location in bearing hole, this runs through slotted eye and extends to ring set and leave a suitable spacing with its bottom, its improvements are: described ring set is that a cross section is triangular in shape and have suitable thickness, and this wall is the hollow ring set with a suitable tapering, in addition, this runs through the position that slotted eye extends to ring set, be the middle position of this ring set triangle bending place, and leave suitable spacing with the ring set bottom.

The utility model preferred embodiment is described with reference to the accompanying drawings as follows:

Fig. 1 is for commonly using screw belt schematic perspective view ().

Shown in Fig. 7,8,9, it is respectively three kinds of different embodiments' of the utility model schematic perspective view, be on a body 1, to be provided with some bearing holes 2 that can ccontaining screw head, and the lower edge in this bearing hole 2 extends a ring set 3, and be provided with some slotted eyes 4 that run through in the appropriate location in bearing hole 2, this runs through slotted eye 4 and extends to ring set 3 and leave a suitable spacing with its bottom; It mainly designs and is: this ring set 3 is that a cross section is triangular in shape and have suitable thickness, and this wall is the hollow ring set with a suitable tapering, in addition, this position of running through that slotted eye 4 extends to ring set 3 is the middle position of these ring set 3 triangle bending places, and leaves a suitable spacing with ring set 3 bottoms.

Please consult Figure 10 again, 11, shown in 12, by said structure, this ring set 3 is designed to the triangle of taper, except having the ductility that expands outwardly, and effectively absorb outside the improper strength, and because of leg-of-mutton turning point has suitable stress, thereby ring set 3 walls inwardly can be suppressed, so improper propelling movement power that is produced during screw in installing when nailing maching, and screw and ring set 3 are non-is the outside expansionary force of screw that same center line produces, all can be absorbed effectively by leg-of-mutton ring set 3, and by the inside strength of suppressing of ring set 3 walls, and its three surface of contact are coated effectively, supporting screw makes screw be vertical angle with body 1.

Moreover, because ring set 3 cross sections are triangular in shape, and leg-of-mutton turning point is to have bigger stress, run through two set turning point middle positions of slotted eye 4 with respect to this, be the most weak part of stress, so when screw head was subjected to the nailing maching shear spinning, this triangle ring set nature broke by running through slotted eye place (the most weak part of stress), and break away from body 1 smoothly, and screw togather with object.

See also Figure 13, ring set 3 of the present utility model has the suitable tapering except aforesaid, and it can be implemented as the ring set 3 of complete vertical walls.

In addition, the structure in screw belt body 1 of the present utility model and bearing hole 2, it is except can be as Fig. 7, Fig. 8 or the form shown in Figure 9, body 1 and the bearing hole 2 that also can adopt other corresponding form.

The cross section of above-mentioned ring set is best with the equilateral triangle.

This shows that the utility model really can reach its intended purposes, and makes ring set be designed to leg-of-mutton state, so that it has splendid ductility and covering property, and then when wearing screw, ring set can reach the purpose of coating, supporting screw firmly.

In sum, the utility model has the practical effect that can obviously improve product really, and it is really unprecedented, so meet the utility model patent important document.
