Service HotlineThe above riveting requires special tools and equipment, which cannot be used in actual specific occasions. In the case of no electricity and no air, only manual tools can be used; and manual tools cannot be used for large types of rivets due to limited human strength. Moreover, after the rivet is disassembled, the rivet itself will be destroyed and cannot be reused.
A T-bolt with anti-slip teeth includes a block-shaped bolt head and a screw rod, the bolt head and the screw rod are T-shaped, the screw head is provided with anti-slip teeth on the side end surface of the screw, and the screw end surface is provided with grooves ; The anti-skid teeth protrude from the side end face of the screw on the bolt head, the anti-skid teeth are strip teeth or reticulated teeth, and their cross-section is triangular; or hexagonal slot etc. The T-bolt with anti-skid teeth of the utility model can not only be quickly inserted into the T-shaped groove, but also ensure reliable connection, and the bolt does not follow the rotation during the tightening of the nut.
The purpose of this utility model is to solve the problems in the prior art, and proposes an installation structure which adopts T-bolt and groove matching, which can make the installation of the bolt more convenient, the degree of tightening is higher, the service life is longer, and the Routine replacement and maintenance.
A kind of nut provided by Yueluo. The nut is in the shape of a casing and is provided with a threaded section. The hole walls at both ends of the threaded section are respectively provided with an annular shape and two grooves, and the notch of the groove points to the hole core. The hole diameter at the notch of the annular groove at the front end of the screw-in direction is larger than the nominal size of the thread segment, and the hole diameter at the notch of the annular groove at the rear end of the screw-in direction is smaller than the nominal size of the thread segment.
At present, there are mainly the following methods for classifying screws of different lengths mixed together: First, visual identification and manual sorting. This method is time-consuming, labor-intensive and inefficient. Second, the screws are centrifuged and screened according to the quality and size of the screws. However, the quality of screws of the same length is not necessarily the same when the materials of the screws are different. Third, sorting is carried out using a screening device with sieve holes, but the sieve holes are generally simple geometric shapes, which can only roughly distinguish the length of the screws. Moreover, the specific position where the screw falls into the screen hole will also affect the degree of screening. It can be seen that the above-mentioned methods for classifying screws all have the problem of poor effect.
