Abstract
The utility model discloses an adjustable bolt locking mechanism which comprises a base, a hollow bolt and a connecting bolt, wherein a threaded through hole is formed in the base, the base is installed on the hollow bolt through the threaded through hole in a sleeved mode, the hollow bolt is in threaded fit with the threaded through hole, the hollow bolt is installed on a screw of the connecting bolt in a sleeved mode, a locking nut is installed at the end of the hollow bolt in a sleeved mode, and the locking nut is in threaded connection with the hollow bolt. According to the adjustable bolt locking mechanism, the compressing function and the resisting function are integrated, the distance between different parts can be adjusted accurately and effectively, the structure is simplified, cost is reduced, occupied space is reduced greatly, and the distance between a part to be locked and other parts can be adjusted accurately; due to the combination of pulling and resisting, pre-tightening force is increased, loosening can be effectively prevented, external shock can be borne, and reliability is improved; the mechanism is simple in structure, convenient to adjust, economical and practical.
Description
Technical field
The utility model relates to a kind of link, is specifically related to a kind of adjustable screw bolt locking mechanism.
Background technique
At present, between accurate adjustment component and equipment or parts, when positional distance, traditional structure is that two groups of bolts are used in conjunction with substantially, realizes for one group and compressing, and realizes supporting for one group and opens, and when adjusting, need to separately operate, and adjusts inconvenience.Bolt in addition, because machinery is in the process of operation, can produce certain vibrations, so after using after a while, usually can produce relaxation phenomenon in connecting, the serious security incident that even can cause.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of adjustable screw bolt locking mechanism, and it is simple in structure, easy to adjust, economical and practical, can effectively regulate the distance between each parts.
The utility model discloses a kind of adjustable screw bolt locking mechanism, comprise base, hollow bolt and connecting bolt, described base is provided with tapped through hole, described base by thread through hole is set on hollow bolt, described hollow bolt and tapped through hole screw-thread fit, described hollow bolt is set on the screw rod of connecting bolt.
Further, between described hollow bolt and the bolt head of connecting bolt, be provided with packing ring.
Further, described packing ring is spring washer.
Further, described hollow bolt end is set with locking nut, and described locking nut is threaded with hollow bolt.
The beneficial effects of the utility model are: the adjustable screw bolt locking mechanism of the utility model, be integrated in one by compression with to opening function, can accurately effectively regulate the distance between each parts, simplified structure, reduce cost, reduced and taken up room greatly; And the positional distance can accurate adjustment being locked between part and other parts; Cause one is drawn a combination of supporting, and has increased pretightening force, can effectively prevent from becoming flexible, and bears external impact, has increased reliability; It is simple in structure, easy to adjust, economical and practical.
Brief description of the drawings
In order to make object, technological scheme and the advantage of model utility clearer, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in the figure, the adjustable screw bolt locking mechanism of the utility model, comprise base 3, hollow bolt 4 and connecting bolt 6, described base 3 is provided with tapped through hole 3a, described base 3 is set on hollow bolt 4 by tapped through hole 3a, described hollow bolt 4 and tapped through hole 3a screw-thread fit, described hollow bolt 4 is set on the screw rod of connecting bolt 6.
In the time that the part 1 that is locked needs to adjust the positional distance between other component, bearing 3 is first fixing, then connecting bolt 6 ends are screwed into the part 1 that is locked.In the time that the part 1 that is locked need to be adjusted to the left side, only need be screwed into clockwise adjusting hollow bolt 4, make it that part 1 that is locked is supported and be opened until suitable distance finally compresses connecting bolt 6; Otherwise, in the time that the part 1 that is locked need to be adjusted to the right, only need first connecting bolt 6 to be unscrewed counterclockwise, then screw out counterclockwise suitable distance by adjusting hollow bolt 4, hollow bolt 4 push connecting bolt 6 make to be locked part 1 pull to the right, finally connecting bolt 6 is compressed.
In the present embodiment, between described hollow bolt 4 and the bolt head of connecting bolt 6, be provided with packing ring 5, preferred, described packing ring 5 is spring washer, can further expand and reinforce area, prevents from becoming flexible.
In the present embodiment, described hollow bolt 4 ends are set with locking nut 2, and described locking nut 2 is threaded with hollow bolt 4.When regulating, hollow bolt 4 is locked behind part 1 position, utilize locking nut 2 locked by tightening between base 3 and hollow bolt 4, can effectively avoid because mechanical movement vibrations cause hollow bolt 4 loosening the positional distance that impact is locked between part 1 and other component.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although by the utility model being described with reference to preferred embodiment of the present utility model, but those of ordinary skill in the art is to be understood that, can make various changes to it in the form and details, and not depart from the spirit and scope of the present utility model that appended claims limits.
