specific Embodiment approach

[0053] Specific implementation methods: such as Figure 9 As shown, in the present invention, the first fixing block 11, the second fixing block 12 and the third fixing block 13 are installed in the screw groove 10 to cooperate with the adjustment structure to realize the adjustable length of the bolt. Such as Figure 4 As shown, the threaded notch 6 is cut on the threaded sleeve 3 to cut an adjusting mechanism chamber 7 at the threaded notch 6, which facilitates the installation of the adjusting mechanism 14. Such as Figure 12 As shown, the effect of the bead 19 being installed on the upper end surface of the adjusting plate 27 is: on the one hand, the bead 19 adopts a wear-resistant material, which can prevent the mechanical wear of the nut 5 to the bead 19; on the other hand, when the nut 5 enters the screw sleeve 3 The bead 19 can be pressed into the cavity 7 of the adjusting mechanism, and then the adjusting mechanism 14 can cooperate with the fixed block installed in ...

Abstract

The invention belongs to the technical field of bolts and particularly relates to an overstrength bolt with the adjustable length. The overstrength bolt comprises a screw cap, a screw, a thread sleeve, a nut, an adjusting mechanism, a first triggering mechanism and the like. In the process that the nut enters the thread sleeve in a threaded fit mode, the nut downwards presses a pressing strip towards an adjusting mechanism cavity, and the adjusting mechanism is triggered; at the moment, the adjusting mechanism is matched with a first fixing block, a second fixing block and a third fixing blockin a screw groove to achieve one of the six kinds of adjustable lengths; compared with a traditional bolt technology, the overstrength bolt can adapt to connection of different workpieces through theapproach of the six kinds of adjustable bolt lengths, the problem that various traditional bolts need to be replaced during connecting of the different workpieces is solved, and the purpose of savingbolt materials is achieved indirectly; and the overstrength bolt is compact in structure and has the good practical effect.

Description

technical field [0001] The invention belongs to the technical field of bolts, in particular to a super-strong bolt with adjustable length. Background technique [0002] At present, when connecting workpieces with different thicknesses, bolts of different lengths are selected for fixing according to the thickness of different workpieces. In special cases, ordinary type bolts sometimes cannot fix super-thick workpieces; or when connecting workpieces with different thicknesses, due to the limited type of bolts they carry, they cannot fix workpieces with different thicknesses; therefore, it is necessary to design a A bolt with different lengths can be adjusted to achieve the purpose of adapting to workpieces with different thicknesses. [0003] The present invention designs a super strong bolt with adjustable length to solve the above problems. Contents of the invention [0004] In order to solve the above-mentioned defects in the prior art, the present invention discloses a...
