Abstract
The utility model relates to a standard fastener, in particular to a T-shape bolt fastener, which comprises a T-shape bolt, a nut and a set piece, wherein the set piece is divided into two oppositely distributed crescents, the top of the set piece is a convex shoulder, the end of the convex shoulder is connected with the nut, and the set piece is arranged on both sides of the bolt pillar of the T-shape bolt and is fixed by the nut. The utility model has the advantage of one-way mounting and is characterized in easy fixing along the bolt radial direction with easy mounting and use, simple structure and low cost.
Description
Technical field
The utility model relates to standard fasteners, relates in particular to the securing means of T type bolt.
Background technique
T type bolt generally is used for fastening between two couplings that a side is difficult for entering, realizes unidirectional installation, for example: mill housing, machine tool guideway etc. fastening.Because coupled have waist shaped hole, thus generally can only be used for along bolt axis to fastening and location, for along bolt location radially, waist shaped hole cannot be finished.Coupling can only axially fasten along bolt like this, radially has big space along bolt, may produce loosening, thereby the quality and the precision of influence location.
Summary of the invention
The utility model has overcome existing T type bolt and has radially had big space, is difficult for location defect along bolt, and a kind of T type bolt clamp device is provided.T type bolt clamp device have can unidirectional installation advantage, have again along bolt radial location characteristics easily, easy to install, simple in structure, cost is low.
The utility model is achieved in that a kind of T type bolt clamp device, comprise T type bolt, nut, positioning block, positioning block is two crescent shape that distribute relatively, and the positioning block top is a convex shoulder, the convex shoulder end is connected with nut, and positioning block is positioned at the double-screw bolt both sides of T type bolt and fastening by nut.
Above-mentioned T type bolt clamp device, described positioning block convex shoulder end is connected with lock washer, and lock washer is fastening by nut.
Above-mentioned T type bolt clamp device, described positioning block crescent shape inner side surface is the plane.
Working principle of the present utility model is on the basis of existing T type bolt, at the double-screw bolt both sides of T type bolt installing and locating piece, the positioning block end is connected with nut, positioning block inserts in the waist shaped hole of coupling, the double-screw bolt of T type bolt contacts with the positioning block inner plane, and like this, the space between T type bolt and positioning block is very little, be convenient to the radial location of T type bolt, also T type bolt played the locking effect.
The utility model is compared with existing T type bolt, and the advantage that existing T type bolt can unidirectional installation has again along bolt radial location characteristics easily, promptly has the three-dimensional orientable characteristics of plain bolt, and easy to install, simple in structure, cost is low.
Description of drawings
Fig. 1 is the utility model T type bolt clamp device structural representation, and Fig. 2 is the right elevation of Fig. 1, Fig. 3 be among Fig. 1 A-A to cross-sectional schematic, Fig. 4 be among Fig. 1 B-B to cross-sectional schematic.
Among the figure: 1 positioning block, 2 lock washers, 3 nuts, 4 T type bolts, 5 couplings, 6 double-screw bolts, 7 bolt tops.
Embodiment
Provide a better embodiment of the present utility model below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of T type bolt clamp device, comprise T type bolt 4, nut 3, positioning block 1, positioning block 1 is two crescent shape that distribute relatively, positioning block 1 top is a convex shoulder, the convex shoulder end is connected with nut 3, and positioning block 1 is positioned at double-screw bolt 6 both sides of T type bolt 4 and fastening by nut 3.Positioning block 1 places in the waist shaped hole of coupling 5, positioning block 1 crescent shape top convex shoulder rests on coupling 5 waist shaped holes and matches with waist shaped hole, the double-screw bolt 6 that nut 3 passes bolt is pressed on the convex shoulder of positioning block 1 coupling 5 is fastening, bolt 4 is both by axially fastening along bolt 4, can not move radially along bolt 4 again, so have the three-dimensional position effect.Positioning block 1 convex shoulder end also can be affixed with lock washer 2, is convenient to directly positioning block 1 be filled in the waist shaped hole of coupling 5, and it is fastening with positioning block 1 that nut 3 compresses lock washer 2.Positioning block 1 with being connected of lock washer 2 can also be: directly two crescent shape positioning blocks 1 are fixed on the lock washer 2, and have need not convex shoulder.Positioning block 1 crescent shape inner side surface is the plane, makes the double-screw bolt 6 of T type bolt 4 contact with positioning block 1 inner plane, and like this, the space that T type bolt 4 and positioning block are 1 is very little, is convenient to the radial location of T type bolt 4, also T type bolt 4 is played the locking effect.
Claims (3)
1. a T type bolt clamp device comprises T type bolt, nut, it is characterized in that this securing means also comprises positioning block, positioning block is two crescent shape that distribute relatively, the positioning block top is a convex shoulder, and the convex shoulder end is connected with nut, and positioning block is positioned at the double-screw bolt both sides of T type bolt and fastening by nut.
2. T type bolt clamp device according to claim 1 is characterized in that positioning block convex shoulder end is connected with lock washer, and lock washer is fastening by nut.
