Specific embodiment
In the following, the utility model is specifically described by illustrative embodiment.It should be appreciated, however, that not having In the case where being further discussed below, element, structure and features in an embodiment can also be advantageously incorporated into other implementations In mode.
In the description of the present invention, it should be noted that the orientation or positional relationship of the instructions such as term "inner", "outside" To be merely for convenience of describing the present invention and simplifying the description based on attached positional relationship shown in FIG. 1, rather than instruction or dark Show that signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as pair The limitation of the utility model.
As Figure 1-Figure 4, the utility model embodiment is related to a kind of unilateral bolt, including tightening latch 1, one end of tightening latch 1 With bolt head 11,1 periphery of tightening latch is successively arranged with sleeve 2, gasket 3 and nut 4 from 11 end of bolt head to its other end;Bolt First 11 close to one end of sleeve 2 in pyramidal, the small head end of frustum close to sleeve 2, stub end far from sleeve 2, small head end Outer diameter is less than 2 internal diameter of sleeve, and the outer diameter of stub end is greater than 2 internal diameter of sleeve;Sleeve 2 is equipped with a plurality of axis close to one end of bolt head 11 To open slot 21;Nut 4 is threadedly coupled with tightening latch 1.
Above-mentioned unilateral bolt, bolt head 11 are arranged to pyramidal close to one end of sleeve 2, and sleeve 2 is close to bolt head 11 one end is equipped with open slot 21, and by the cooperation of this sleeve 2 and bolt head 11, when tightening nut 4, sleeve 2 is close to spiral shell One end of bolt head 11 can be strutted along open slot 21, realize the fixation of unilateral bolt.The unilateral bolt arrangement is simple, low in cost, And easy construction.
In order to make sleeve 2 close to one end of bolt head 11 convenient for strutting, as a preference, as shown in figure 3, sleeve 2 Wall thickness is gradually thinning to one end close to bolt head 11 from one end close to gasket 3.Further, a plurality of open slot 21 is distributed in Sleeve 2 is conducive to strutting for sleeve 2.In the present embodiment, the quantity of open slot 21 is 4, it should be noted that open slot 21 Quantity be advisable in 3-6 item, quantity is very few to be unfavorable for strutting for sleeve 2, quantity each limb part that excessively then sleeve 2 is formed after strutting Easy fracture.In addition, the length of open slot 21 is the 80%-90% of 2 length of sleeve, to meet the connection need of different-thickness junction It wants.
For the ease of clamping tightening latch 1 during tightening nut 4, to prevent unilateral bolt from dallying, tightening latch 1 is far from bolt First 11 one end is equipped with clamping part 12.In one embodiment, as shown in Fig. 2, clamping part 12 includes being set to 1 outer surface of tightening latch Multiple sections, the production easy to process of this clamping part 12.It should be noted that section is specially two, two in the present embodiment Section is arranged relative to the axisymmetrical of tightening latch 1, and this 12 processing cost of clamping part is low, and multiple clamping apparatus can be used and pressed from both sides It holds.In another embodiment, as shown in figure 4, section is specially six, six sections surround regular hexagonal prism shape, using plum blossom Spanner clamping.It is understood that the utility model is not limited to the clamping part 12 of the above-mentioned type, those skilled in the art The clamping part 12 of other shapes can be used, as long as convenient for clamping.
Further, it is softened deformed support force since gasket 3 needs to bear sleeve 2, in order to guarantee bonding strength, As a preference, 0.7-1.2 times with a thickness of 4 thickness of nut of gasket 3.Otherwise, the thickness of gasket 3 is excessively thin, not can guarantee Bonding strength, and the thickness of gasket 3 is blocked up, processing cost is higher.
As shown in figure 5, the application method of above-mentioned unilateral bolt are as follows: sleeve 2, gasket 3 and nut 4 are successively placed on tightening latch 1 On, it is assembled into unilateral bolt;Unilateral bolt is inserted into the bolt hole processed on the outside of steel plate 5, unilateral bolt insertion When bolt head 11 towards the inside of steel plate 5;Tightening latch 1 is clamped, while turning nut 4 until sleeve 2 is close to one end of bolt head 11 It is strutted along open slot 21, completes connection, wherein the length of 5 exterior portion of steel plate can be located at by measurement tightening latch 1 to examine sleeve Whether 2 strut.
