Abstract
The utility model relates to a kind of bolt of improvement, comprise nut and be installed on the screw bottom nut, the joint of nut and screw is provided with multiple elastic pressuring plate, screw top cover has removable insole pieces, the upper-end surface of removable insole pieces is the arc-shaped of mating with elastic pressuring plate, the bottom of removable insole pieces is provided with the ratchet of multiple radial direction setting, is pointed tooth end bottom screw.The utility model has the advantages that: the ratchet bottom removable insole pieces can increase the frictional property between bolt and fixation, make can better be fixed between bolt and fixation; Bolt is in the process of tightening, and the arc surface of removable insole pieces needs the pressure bearing elastic pressuring plate, and bolt is more easily tightened; And be also provided with between elastic pressuring plate with removable insole pieces and also realize fricton-tight by coordinating of groove and inserted block, ensure that the service behaviour of bolt; Pointed tooth end bottom screw facilitates bolt to look for a little to tighten fixing.
Description
Technical field
The utility model relates to a kind of bolt, particularly relates to a kind of bolt of improvement, belongs to standard piece and manufactures field.
Background technique
The bolt of prior art comprises nut and screw rod, and nut is fixedly connected with screw rod, leaves defect in actual use at the bolt of said structure: not easily tighten and also easily occur to loosen the phenomenon dropped, thus affecting the functional reliability of equipment.Therefore, a kind of new technological scheme should be provided to solve the problem.
Summary of the invention
The purpose of this utility model is: the bolt providing a kind of improvement.
For achieving the above object, the technical solution adopted in the utility model is: a kind of bolt of improvement, comprise nut and be installed on the screw bottom nut, the joint of nut and screw is provided with multiple elastic pressuring plate, screw top cover has removable insole pieces, the upper-end surface of removable insole pieces is the arc-shaped of mating with elastic pressuring plate, and the bottom of removable insole pieces is provided with the ratchet of multiple radial direction setting, is pointed tooth end bottom screw.
Be provided with groove between elastic pressuring plate and screw, the side of groove is provided with the groove of outwardly convex, and central position, removable insole pieces upper-end surface is provided with the plug-in unit mated with groove, and plug-in unit is provided with the inserted block mated with groove.
Due to the application of technique scheme, the utility model compared with prior art tool has the following advantages:
Ratchet bottom removable insole pieces can increase the frictional property between bolt and fixation, makes can better be fixed between bolt and fixation; Bolt is in the process of tightening, and the arc surface of removable insole pieces needs the pressure bearing elastic pressuring plate, and bolt is more easily tightened; And be also provided with between elastic pressuring plate with removable insole pieces and also realize fricton-tight by coordinating of groove and inserted block, ensure that the service behaviour of bolt; Pointed tooth end bottom screw facilitates bolt to look for a little to tighten fixing.
