Compared with the existing bolt connection pair, the utility model reduces a gasket and a spring pad, changes the hexagonal nut into the flange nut, and reduces the mass on the premise of ensuring the looseness prevention.
Description
Technical Field
The utility model relates to the field of bolt products, in particular to a lightweight bolt connection pair.
Background
The bolt connection pair has the requirement on the light weight in some fields, especially in the installation of photovoltaic support, has higher requirement on locking and light weight, and current bolt connection pair, as shown in fig. 3, for locking, usually adopts a bolt, two gaskets, a bullet pad and a hex nut to constitute, because the part is many, consequently weight is big, moreover, because by the clamp piece more, there is the displacement each other, will have the risk of becoming flexible after rotating.
Disclosure of Invention
In order to overcome the defects, the utility model provides an anti-loose light-weight bolt connection pair which comprises a bolt body, wherein one side of the bolt body is a smooth surface, the other side of the bolt body is a threaded surface, a gasket is arranged on the smooth surface, and a flange nut is connected to the threaded surface in a threaded manner.
Preferably, the bolt body is a hot dip zinc bolt.
Preferably, the flange nut comprises a nut part and a flange part, the nut part and the flange part are integrally arranged, and the combination of a gasket, a spring pad and a hexagonal nut of the original bolt connection pair is replaced by one flange nut.
Preferably, the nut part is a hexagonal nut, and the ratio of the major diameter of the threaded surface to the total thickness of the flange nut is 1: (0.6-0.7), and/or the ratio of the major diameter of the thread surface to the thickness of the flange portion is 1: (0.12-0.14), the ratio of the major diameter of the thread surface to the opposite side distance of the hexagonal nut is 1: (1.4-1.5), the ratio of the major diameter of the threaded surface to the diameter of the flange portion is 1 (2.5-2.75).
The beneficial effects of the utility model are as follows: the gasket and the elastic pad are reduced, and the hexagonal nut is changed into the flange nut, so that the integral weight is reduced on one hand, and the loose is difficult to occur due to fewer accessories on the other hand.

Detailed Description
The utility model will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic views illustrating the basic structure of the present utility model by way of illustration only, and thus show only the constitution related to the present utility model.
In the description of the present utility model, it should be noted that the directions or positional relationships indicated by the terms "upper", "lower", "inner", "outer", "front", "rear", "both ends", "one end", "the other end", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific direction, be configured and operated in the specific direction, and thus should not be construed as limiting the present utility model.
In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "provided," "connected," and the like are to be construed broadly, and may be fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; the connection may be direct or indirect through an intermediate medium, the connection between the two elements may be internal, the fixed connection may be welding, cementing, etc., and it is understood that the specific meaning of the terms in the present utility model will be specific to those skilled in the art.
As shown in fig. 1-2, a lightweight bolt connection pair comprises a bolt body 1, wherein one side of the bolt body 1 is provided with a smooth surface 2, the other side of the bolt body is provided with a thread surface 3, the thread surface adopts a strong thread, the smooth surface 2 is provided with a gasket 4, the thread surface 3 is connected with a flange nut in a threaded manner, the flange nut comprises a nut part 5 and a flange part 6, and the nut part 5 and the flange part 6 are integrally arranged. Compared with the existing bolt connection pair, the utility model reduces a flat pad and a spring pad, on one hand, the weight of the bolt pair is reduced; on the other hand, the number of accessories is reduced, and the possibility of loosening is reduced.
The bolt body is a hot-dip galvanized bolt, the corrosion resistance of the bolt body is improved through hot-dip galvanizing, and the service life of the bolt body is prolonged.
The nut part 5 is a hexagonal nut, and the ratio of the major diameter of the threaded surface to the total thickness of the flange nut is 1: (0.6-0.7), the ratio of the major diameter of the threaded surface to the thickness of the flange portion is 1: (0.11-0.14), the ratio of the major diameter of the thread surface to the opposite side distance of the hexagonal nut is 1: (1.4-1.5), the ratio of the major diameter of the threaded surface to the diameter of the flange portion is 1 (2.5-2.75).
Taking a flange nut B on an M16 bolt with the structure, wherein the total thickness of the flange nut B is 10.5mm, the thickness of a flange part is 1.8mm, the distance between opposite sides of the nut part is 23.67mm, and the diameter of the flange part is 41.5mm; the hexagonal nut on the common full-thread M16 bolt is taken, the total thickness of the nut is 14.8mm, the opposite side distance of the nut part is 23.67mm, and the hexagonal nut is matched with a spring pad, so that the fastener A is formed. The tests A and B were carried out according to the national standard GB/T10431-1989 method for testing transverse vibration of fasteners. The test results are shown in FIG. 4, where the axial force of A is smaller and smaller over time, and the axial force of B can be maintained between 60KN and 70 KN. Namely, for nuts of the same specification, the anti-loosening performance of the flange nut is greatly superior to that of a common standard nut and spring pad combination.
The present utility model has been made in view of the above-described circumstances, and it is an object of the present utility model to provide a portable electronic device capable of performing various changes and modifications without departing from the scope of the technical spirit of the present utility model.
