Abstract
A bolt comprises a bolt head (1) and a threaded rod (2) and is characterized by further comprising a ball (3) and a spring (4), wherein a groove (5) is formed in the bolt head (1); the ball (3) and the spring (4) are positioned inside the groove (5); one end of the spring (4) presses against the bottom end of the groove (5); and the other end of the spring (4) presses against the ball (3). Through arrangement, the bolt is convenient to install.
Description
Technical field
The utility model relates to fastener areas, specifically is meant a kind of bolt.
Background technique
Bolt as a kind of install and fixedly the fastening piece of section bar be widely used by people; The bolt kind that uses in the existing assembly process is a lot; But be the structural design that adopts the bolt standard piece in general mostly, that is to say that each bolt in the section bar installation all is to use with the form of standard piece; In real life, it is found that there is following deficiency in the design of this bolt standard piece: 1, because of bolt head can not fully contact with the section bar groove bottom, thereby bolt slidably reciprocates easily and drops in the section bar groove, is not easy to install.2, because the interior space of section bar groove is limited, causes to install and should not dismantle later, dismounting should not be installed later.
Summary of the invention
The technical problem that the utility model will solve is that a kind of loosening bolt easy for installation and difficult is provided.
For solving the problems of the technologies described above, the technological scheme that the utility model provides is: bolt head and threaded stem; It is characterized in that: it also comprises ball and spring; Has groove on the bolt head; Ball and spring are positioned at groove; Spring one end pushes against the groove bottom; The spring the other end pushes against ball.
After adopting above structure, the utlity model has following advantage: bolt head just can push against with the section bar groove bottom, and it is fixed on the section bar automatically, is convenient to assembling; The phenomenon of sliding and dropping can not appear.Bolt head has possessed scalability, installs later detachably, and dismounting still can continue to install later.
As improvement, recess axis line and threaded stem dead in line make the ball that exposes bolt head partly be maximization, and scalable scope is bigger.
As improvement, groove notch diameter is less than diameter of the steel ball; The ball horizontal axis is lower than groove notch horizontal plane.
As preferably, be positioned at the ball employing steel ball of bolt head groove, such ball slides in the section bar groove and can not cause the ball profile impaired, makes the life-span of bolt increase greatly.
Description of drawings
Fig. 1 is the front view of the bolt that relates to of the utility model.
Fig. 2 is the bolt side structure schematic representation that the utility model relates to.
As shown in the figure: bolt head 1, threaded stem 2, ball 3, spring 4, groove 5;
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description.
Can know by Fig. 1, Fig. 2 and Fig. 3, a kind of bolt, it comprises: bolt head 1, threaded stem 2, ball 3, spring 4; There is groove 5 on the bolt head 1; Spring 4 one ends push against groove 5 bottoms; Spring 4 the other ends push against ball 3; Ball 3 projections are higher than bolt head 1.Recess axis overlaps with threaded stem axis line, makes the ball that exposes bolt head partly for maximum, and scalable scope is bigger.The ball horizontal axis is lower than groove notch horizontal plane.
The utility model bolts assemblies process is following: earlier spring 4 is put into groove 5, after ball 3 usefulness drifts are impacted into groove 4, make spring 4 one ends push against groove 5 bottoms, the other end pushes against ball 3, and is again that the polishing of groove 5 notches is level and smooth.
This description does not have restricted, and shown in the figure also is one of mode of execution of the utility model, and practical structure is not limited thereto.If generally speaking those of ordinary skill in the art is enlightened by it, under the situation that does not break away from the utility model creation aim,, all should belong to the protection domain of the utility model without creationary mode of structure similar and the embodiment of designing with this technological scheme.
