Abstract
The utility model relates to a bolt, which comprises a bolt body, wherein the bolt body is formed by connecting a bolt head and a screw; the bolt head is flat; an eccentric hole is formed in the bolt head; the section of the bolt head is circular; and a plurality of bulges are uniformly arranged on the front surface and the back surface of the bolt head. According to the bolt, the bolt head is flat, and the eccentric hole is formed in the bolt head, so that when the bolt is used, a user can directly screw down or screw off the bolt with a hand; and if the bolt is used for locking some sets of precision machinery, a cylindrical stick is inserted into the eccentric hole and can rotate. The bolt is easy to operate, time-saving and is not required to be screwed down or screwed off by screwdrivers of different types, so that the burden of a user is reduced.
Description
Technical field
The utility model relates to a kind of bolt, and especially a kind of bolt that needn't use screw-driver to tighten or to turn on belongs to the device technology field that fastening or fixed component or machine parts are used.
Background technique
Bolt is by bolt head and screw rod (having externally threaded cylindrical body) one type of fastening piece dimerous, is used to be fastenedly connected two machinery parts that have through hole.This Connecting format claims that bolt connects, and it is to belong to removably connect that bolt connects.Existing bolt will be used screw-driver in use usually, when bolt need be tightened or turn on, need hole with screw-driver inserting bolt head in, the rotary screw cutter is operated lengthy and tedious then; In addition, need prepare different screw-drivers, carry inconvenience for the bolt of different model.
The model utility content
The utility model purpose is for the deficiency that overcomes existing technology a kind of bolt that needn't use screw-driver to tighten or to turn on to be provided.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of bolt, comprise bolt body, and said bolt body is formed by connecting bolt head and screw rod, and said bolt head is flat; Have eccentric opening on the said bolt head.
Preferably, the cross section of said bolt head is rounded.
Preferably, be equipped with a plurality of convexities on the positive and negative surface of said bolt head.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The described bolt of the utility model; Because bolt head is flat; Have eccentric opening on the bolt head, directly can the described bolt of the utility model tightened or turn on during use, if when the described bolt of the utility model is used for some precision optical machineries and need steps up with hand; Can use a cylinder rod, be inserted in the eccentric opening rotation and get final product.The described bolt of the utility model, easy and simple to handle, save time, needn't carry the screw-driver of different model it is tightened or turns on, alleviated people's burden.
Description of drawings
Below in conjunction with accompanying drawing the utility model technological scheme is described further:
Accompanying drawing 1 is the stereogram of the bolt of the utility model;
Accompanying drawing 2 is the side view of the bolt of the utility model;
Wherein: 1, bolt head; 2, screw rod; 3, eccentric opening; 4, convexity.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Like accompanying drawing 1, the described a kind of bolt of the utility model shown in 2, comprise bolt body, said bolt body is formed by connecting bolt head 1 and screw rod 2, and said bolt head 1 is flat; Have eccentric opening 3 on the said bolt head 1; The cross section of said bolt head 1 is rounded; Be equipped with a plurality of protruding 4 on the positive and negative surface of said bolt head 1.During use, needn't carry the screw-driver of different model and tighten or turn on the described bolt of the utility model, directly can it tightened or turn on hand; The convexity 4 on the positive and negative surface of bolt head 1 can strengthen frictional force, more easily the described bolt of the utility model is tightened or is turned on, if use it in the time of need stepping up in some precision optical machineries; Can use a cylinder rod; Be inserted in the eccentric opening 3 rotation and get final product, easy and simple to handle, save time.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
