Abstract
The utility model relates to a bolt. The bolt comprises a bolt head (1) and a screw rod, and is characterized in that a polygonal groove (3) is arranged on the end surface, which is far away from the screw rod, of the bolt head (1). A filling block matched with the groove (3) is arranged in the groove (3). The utility model provides the bolt which is convenient to disassemble and assemble.
Description
Technical field
The utility model relates to technical field of fastening, specifically is meant a kind of bolt.
Background technique
Bolt head is configured to quadrilateral, hexagon or other polygonal usually in the existing technology, and above-mentioned bolt adopts adjustable spanner or socket wrench mostly when dismounting; These instrument necessary operations spaces are big; On a lot of equipment, because the restriction in space, these assembling tools are very inconvenient when using; After need other interference parts on the equipment being removed one by one enough operating spaces are arranged; With modal hex head bolt is example, and in conjunction with accompanying drawing 1, this bolt comprises bolt head 1 ' and the screw rod 2 ' that links to each other with bolt head 1 '.Further combine accompanying drawing 2, bolt head 1 ' is solid hexagonal structure.The bolt of this structure can only come dismounting through adjustable spanner or socket wrench in use, because these instrument necessary operations spaces are big, bolt is very inconvenient when dismounting.
Summary of the invention
The technical problem underlying that the utility model will solve is that a kind of bolt of easy disassembly is provided.
For solving the problems of the technologies described above, the technological scheme that the utility model provides is: a kind of bolt, and it comprises bolt head and screw rod, bolt head is provided with polygonal groove away from the end face of screw rod.
After adopting above structure; The utlity model has following advantage: bolt head is provided with polygonal groove away from the end face of screw rod; When bolt head transversely the space is not enough the time, can the driving end that match with polygonal groove vertically be inserted in the said polygonal groove, and then the horizontal handle that extends out on the rotating spanner; Can carry out dismounting to bolt, not spend like this and pull down transversely other of bolt and disturb parts just can easily assembling-disassembling bolt.
As preferably, said bolt head is hexagonal structure, and hexagonal structure can match with various Wrenchs, and versatility is better.
As preferably, said groove is hexagonal structure, and hexagonal structure can match with various Wrenchs, and versatility is better.
As preferably, it is minimum that said groove structure triangular in shape, triangular structure take the space of bolt head, little to the intensity effect of bolt head.
As preferably, the degree of depth of said groove is thickness half the of bolt head, and this degree of depth is little to the intensity effect of bolt head.
As improvement, be provided with the filling block that matches with groove in the said groove, filling block can prevent that groove is blocked, also can prevent simultaneously spanner outside bolt head during the application of force groove in the bolt head deform.

Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description.
Specific embodiment one
In conjunction with accompanying drawing 3 and accompanying drawing 4, a kind of bolt, it comprises bolt head 1 and screw rod, bolt head 1 is provided with polygonal groove 3 away from the end face of screw rod.Said bolt head 1 is hexagonal structure.Said groove 3 is hexagonal structure.The degree of depth of said groove 3 is thickness half the of bolt head 1.Be provided with the filling block that matches with groove 3 in the said groove 3.
Specific embodiment two
Further combine accompanying drawing 5 and accompanying drawing 4, a kind of bolt, it comprises bolt head 1 and screw rod, bolt head 1 is provided with polygonal groove 3 away from the end face of screw rod.Said bolt head 1 is hexagonal structure.Said groove 3 structures triangular in shape.The degree of depth of said groove 3 is thickness half the of bolt head 1.Be provided with the filling block that matches with groove 3 in the said groove 3.
During practical implementation, said filling block is and the slug of bolt head 1 away from the end face of screw rod, can be provided with on it that little hanging hole is convenient to be taken out from groove 3, can directly pass through the Magnetic spanner sucking-off.
Need to prove; Below schematically the utility model and mode of execution thereof are described; This description does not have restricted, and shown in the accompanying drawing 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.
