Abstract
The utility model discloses a bolt which comprises a flange plate (1) and a screw rod (2) integrated with the flange plate (1) into a whole; the top part of the flange plate (1) is provided with an inner hexagonal inner hole (3) for a tool to insert into and rotate the bolt; and the axial depth of the inner hole (3) is more than the thickness of the flange plate (2). The bolt has the advantages that: the bolt can be disassembled and assembled simply and conveniently when no bolt head exists.
Description
Technical field:
The utility model relates to a kind of bolt.
Background technique:
In general, form by bolt head, flange plate and screw rod usually as the bolt that connects one of fastening piece in the machinery; Described flange plate is connected between bolt head and the screw rod; The effect of described bolt head is the dismounting of being convenient to bolt; The effect of described flange plate is to increase bolt and be connected frictional force between the part.For the ease of the dismounting of bolt, the shape of described bolt head is configured to hexagon, quadrilateral or Octagon etc. usually.Yet, owing to be subjected to the restriction of installing space, the dismounting of above-mentioned bolt in some special equipments all can can't realize dismounting because of the existence of bolt head, in other words, the space that is connected between part and other part can not hold bolt head, the user can't operate bolt head by tool using, thereby causes bolt head can not play the effect that it carried out dismounting originally.
The model utility content:
The technical problems to be solved in the utility model is to provide a kind of at the bolt that does not have also can carry out simply, easily under the situation of bolt head dismounting.
Technical solution of the present utility model is, a kind of bolt with following structure is provided, it comprise flange plate and with flange plate be holistic screw rod; The top of described flange plate is provided with an endoporus that can be rotated bolt for instrument inserts.
After adopting above structure, compared with prior art, the utlity model has following advantage: because the utility model is under the situation that bolt head is not set, be provided with an endoporus that can be rotated bolt for instrument inserts at the top of flange plate, therefore, the utility model can carry out dismounting simply and easily in some less installing spaces.
Description of drawings:
Fig. 1 is the structural representation of the utility model bolt.
Fig. 2 is that K among Fig. 1 is to schematic representation.
Endoporus as shown in the figure, 1, flange plate, 2, screw rod, 3.
Specific embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
As shown in drawings, in this specific embodiment, the utility model bolt comprises flange plate 1 and is holistic screw rod 2 with flange plate 1; The top of described flange plate 1 is provided with an interior hexagonal internal bore 3 that can be rotated bolt for instrument inserts; The axial depth of described endoporus 3 is greater than the thickness of flange plate 2.
Claims (3)
1, a kind of bolt, it comprise flange plate (1) and with flange plate (1) be holistic screw rod (2), it is characterized in that: the top of described flange plate (1) is provided with an endoporus (3) that can be rotated bolt for instrument inserts.
2, bolt according to claim 1 is characterized in that: the axial depth of described endoporus (3) is greater than the thickness of flange plate (2).
3, bolt according to claim 1 and 2 is characterized in that: described endoporus (3) be shaped as interior hexagon, interior quadrilateral or interior octagon.
