Abstract
The utility model discloses a bolt assembly convenient to operate. The bolt assembly convenient to operate comprises a bolt with an external thread and a bolt head portion, and the bolt head portion is arranged on the top of the bolt. The bolt assembly convenient to operate further comprises a bolt head cover which is arranged on the bolt head portion in a sleeved mode and is matched with the bolt head portion for use. A sleeved hole which has the same shape and size as the bolt head portion is formed in the bolt head cover. According to the technical scheme, the bolt assembly convenient to operate has the advantages that the bolt head cover and the bolt head portion are matched for use, and the problem that part of thin bolt head portions can not be screwed or tightened easily by common tools can be effectively solved; the bolt head cover and the bolt head portion are matched for use, and the problem that the phenomenon of wire sliding occurs to the corner angle of the bolt head portion easily when a small polygonal nut is screwed can be solved; a circle of thin steps are designed to be arranged on the lower edge of the bolt head portion, and the limiting problem of the position of the bolt head cover is solved; the bolt assembly convenient to operate is simple in structure and convenient to operate.
Description
Technical field
The utility model relates to a kind of bolt, is specially a kind of bolt assembly of convenient operation, belongs to technical field of fastening.
Background technique
Bolt be can't do without in daily life is worked as and in the middle of the industrial production manufacturing, and bolt is also referred to as the rice of industry.As seen the utilization of bolt is extensively.The utilization scope of bolt has: electronic product, engineering goods, digital product, power equipment, dynamo-electric engineering goods.Boats and ships, vehicle, hydraulic engineering, even also use bolt in the chemical experiment.Anyway be that super many places have and use bolt.The special precision bolt of using above such as digital product.DVD, the Micro-bolt that photographic camera, glasses, clock and watch, electronics etc. use; Bolt as one of TV, electric product, musical instrument, furniture etc.; Then use large-sized bolt, screw head as for engineering, building, bridge; Traffic tool, aircraft, electric car, automobile etc. then are large stove bolt and use.Bolt is in the industrial vital task of bearing, as long as exist industry on the earth, then the function of bolt is forever important.
Bolt is comprised of screw head and screw rod (with externally threaded cylindrical body) two-part, needs to cooperate with nut, is used for being fastenedly connected two with the part of through hole.
A lot of bolt heads are in order to design needs, and very little very thin, so in use have a lot of problems: thin such as bolt head, then common operation tool is difficult to clamping; And bolt head hour, and common operation tool makes the corner angle stripped thread of bolt head easily.
Therefore designing a kind of bolt assembly of convenient operation, is the technical problem that association area needs to be resolved hurrily.
The model utility content
The purpose of this utility model is for a kind of bolt assembly of convenient operation is provided, to solve the problem of prior art.
The purpose of this utility model is achieved through the following technical solutions:
A kind of bolt assembly of convenient operation comprises that with externally threaded bolt and bolt head, described bolt head is arranged at the top of bolt; Also include a bolt headgear that is set in bolt head and is used with bolt head, described bolt head puts and is provided with the trepanning identical with size with the bolt head shape.
Described trepanning is through hole, blind hole or counterbore.
The medial axis of described bolt headgear overlaps with the bolt medial axis.
Further, at the bolt head lower edge the slim step of one circle is set.One prevents in the vertical direction, directly passes bolt head with the bolt headgear of through hole.The position that the two can limit the bolt headgear prevents from not putting fully, stressed rear generation stripped thread.
According to the bolt assembly that technical solution of the present invention designs, have following beneficial effect:
1, is used by bolt headgear and bolt head, can effectively solves because the problem that the not easy-to-use common tool of the slim bolt head of part screws or tightens.
2, by being used of bolt headgear and bolt head, can solve small-sized polygonal nut when spanner is tightened, the problem of the easy stripped thread of bolt head corner angle.
3, by the slim step of lower edge design one circle at bolt head, solved the bound problem of bolt headgear position.
4, the utility model is simple in structure, and is easy to operate.
Description of drawings
Fig. 1 is bolt arrangement schematic representation of the present utility model;
Fig. 2 is the structural representation of the utility model embodiment 1 bolt headgear;
Fig. 3 is the structural representation of the utility model embodiment 2 bolt headgears;
Among the figure: 1, bolt 2, bolt head 3, bolt headgear 4, trepanning 5, slim step.
Embodiment
Further set forth structural feature of the present utility model below in conjunction with accompanying drawing and specific embodiment.
The bolt assembly of a kind of convenient operation as shown in Figure 1 comprises that described bolt head 2 is arranged at the top of bolt 1 with externally threaded bolt 1 and bolt head 2; Also include a bolt headgear 3 that is set in bolt head 2 and is used with bolt head 2, be provided with the trepanning 4 identical with size with bolt head 2 shapes on the described bolt headgear 3.
Described trepanning 4 is through hole, blind hole or counterbore.
The medial axis of described bolt headgear 3 overlaps with bolt 1 medial axis.
Further, at bolt head 3 lower edges the slim step 5 of one circle is set.One prevents in the vertical direction, directly passes bolt head 2 with the bolt headgear 3 of through hole.The position that the two can limit bolt headgear 3 prevents from not putting fully, stressed rear generation stripped thread.
Embodiment 1
Bolt headgear 3 as shown in Figure 2, its trepanning are blind hole.
Embodiment 2
Bolt headgear 3 as shown in Figure 3, its trepanning are through hole.
