Abstract
The utility model discloses an anti-skid half-thread bolt, which is to provide a half-thread bolt with uneasiness for slipping and wear resistance. The anti-skid half-thread bolt comprises a bolt head and a bolt rod, wherein a thread is arranged on the bolt rod; and anti-skid grains are arranged on the bolt head. Preferably, distances among the anti-skid grains are 0.3-1 mm. Preferably, the bolt head is hexagonal. As the anti-skid grains are arranged on the bolt head, the anti-skid half-thread bolt disclosed by the utility model has the advantages of greater friction force, uneasiness for slipping and greater wear resistance when the bolt head is clamped by a wrench.
Description
Technical field
The utility model relates to mechanical field, especially relates to a kind of partial thread bolt.
Background technique
Bolt is widely used in the connection between the part as mechanical fastener.The bolt head of existing plain bolt generally all is shapes such as hexagonal, interior hexagonal, square toes, and these bolts are used very extensively, use also very convenient.Generally, screw or can clamp bolt head through spanner when unscrewing bolt and operate.But in the actual mechanical process, when narrow and small, spanner skids easily in the gripping space, and often through after repeatedly using, bolt head is easy to wear, makes the recycling rate of waterused of bolt reduce.
Summary of the invention
For addressing the above problem, the purpose of the utility model is to provide a kind of and is difficult for skidding and anti abrasive partial thread bolt.
A kind of anti-skidding partial thread bolt comprises bolt head, bolt shank, and said bolt shank is provided with screw thread, and said bolt head is provided with anti-skidding line.
As preferably, be spaced apart 0.3mm～1mm between the said anti-skidding line.
As preferably, said bolt head is a hexagon.
The partial thread bolt that the utility model provides makes that through on bolt head, being provided with anti-skidding line frictional force was bigger when spanner was clamped bolt head, is difficult for skidding, and more wear-resistant.
Description of drawings
Fig. 1 is the structural representation of anti-skidding partial thread bolt
Accompanying drawing is indicated tabulation:
The 1-bolt head, 2-bolt shank, 3-screw thread, the anti-skidding line of 4-.
Embodiment
Below in conjunction with accompanying drawing and embodiment, further illustrate the utility model, should understand following embodiment only be used to the utility model is described and be not used in the restriction the utility model scope.Need to prove; Describe below the word " preceding " that uses, " back ", " left side ", " right side ", " on " and D score refer to the direction in the accompanying drawing, word " interior " and " outward " refer to respectively towards or away from the direction of specific features geometrical center.
As shown in Figure 1, a kind of anti-skidding partial thread bolt comprises bolt head 1, bolt shank 2, said bolt shank is provided with screw thread 3, said bolt head 1 radially be provided with the anti-skidding line 4 of projection fine strip shape.Through the setting of anti-skidding line, spanner clamps that bolt head is screwed or to unscrew when operation frictional force bigger, is difficult for skidding.
When the anti-skidding partial thread bolt that the utility model is provided is applied to some parts that need frequently take off, connect,, therefore can be screwed into screwing of capable bolt or unscrews operation through hand because anti-skidding line increases frictional force, convenient simple.Bolt in addition, after repeated multiple times was used, anti-skidding line can be ground off earlier, makes that the body of bolt head is more wear-resistant.As preferably, the interval of anti-skidding line is arranged on 0.3mm～1mm and is advisable, and when saving material, reaches good skidproof effect.
As preferably, the bolt head of anti-skidding partial thread bolt is a hexagon common in the industry.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned technological means, also comprises the technological scheme of being made up of above technical characteristics combination in any.
