Abstract
The utility model discloses a cross open type bolt used for fastening machines and apparatus, and the cross open type bolt is formed as integration by a lead screw 4 and a bolt head 1. The upper part of the bolt head is provided with a lateral device open slot 2 and a longitudinal open slot 3, and the two slots are crossed. The utility model can efficiently improve and extend the service life of the screw bolt after collapse damage, and the utility model has simple structure and simple use.
Description
The utility model relates to a kind of cross opening shape bolt that is used for fastening machine, equipment.
Present hexagon bolt must make any one group of parallel opposite side of wrench mouth clamping bolt in use, withdraw from repeatedly then, insert the spanner mouth and carry out work, and wrench contacts the line of force on the hexagonal shaped corner angle with bolt, the easy plate of corner angle collapses damage with the inefficacy of " angle, the garden " form of skidding, and influences the working life of bolt.
The purpose of this utility model is that a kind of improved cross opening shape bolt will be provided, it can improve effectively and prolong bolt because of plate collapse the damage after working life.
The purpose of this utility model is achieved in that and has transverse opening and longitudinal opening groove that on bolt head it is cross.When bolt collapses damage because of plate after, about carrying out with flat screw-driver, or assemble with Philips screwdriver.
The utility model is because only need open a cross bath, so structure is simple especially on former bolt head; Simultaneously owing to have in mind and do not lie in the working life that prolongs bolt, it to bolt head and mode of operation without any special requirement; Because the cross of being opening slot is arranged above the bolt head, can increase the instrument up and down of bolt again in addition.
Further specify below in conjunction with the structure and the effect of accompanying drawing model utility.
Fig. 1 is a plan view of the present utility model.
Fig. 2 is a plan view of the present utility model.
With reference to accompanying drawing, screw mandrel (4) and bolt head (1) constitute whole.Have transverse opening groove (2) and have longitudinal opening groove (3) on bolt head on bolt head and be cross, bolt adopts steel, copper or other metal material processing to form.
