Bolt with hexagonal threaded end

Abstract

The invention discloses a bolt with a hexagonal threaded end. The bolt comprises a bolt head, a threaded rod connected with the bolt head and a nut in matched connection with the threaded rod. The outer surface of the end of the threaded rod is sleeved with the threaded end in matched connection with the threaded rod, the threaded end is used for fixing the threaded rod when the bolt is screwed up, and the threaded end is of a hexagonal structure. The bolt is provided with the hexagonal end capable of fixing the threaded rod, the defect that when a traditional bolt is fastened, one end needs to be fixed, and the other end needs to be screwed up is avoided, and connecting components can be fastened at one end of the bolt; therefore, time and labor are saved, the labor intensity is lowered, the production efficiency and work efficiency can be improved, and fastening connection between the connecting components can be guaranteed; convenience and practicality are achieved, and the bolt can be suitable for multiple occasions and worthy of wide popularization.

Description

technical field [0001] The invention relates to a bolt, in particular to a bolt with a hexagonal threaded end. Background technique [0002] Bolts are widely used mechanical parts, including bolt heads and threaded rods, which need to be matched with nuts to fasten and connect two parts with through holes. This connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. Bolt heads include hexagonal head, round head, square head, countersunk head, etc., among which hexagonal head is the most commonly used. Generally, the countersunk head is used where the surface is required to be smooth without protrusions after connection, because the countersunk head can be screwed into the part; the round head can also be screwed into the part, and the tightening force of the square head can be larger, but the size is large. [0003] The structure of the existing bolt assembly is ge...

Problems solved by technology

Generally, the countersunk head is used where the surface is required to be smooth without protrusions after connection, because the countersunk head can be screwed into the part; the round head can also be screwed into the part, and the tightening force of the square head can be larger, but the size is large

[0003] The structure of the existing bolt assembly is generally as figure 2 As shown, including the bolt head, the cylindrical threaded rod with external thread on the bolt head and the nut connected with the threaded rod, such a bolt structure has the following defects: during the tightening process of the bolt, due to the force, the nut And the bolt head inevitably slips or the threaded rod shakes, so that it is necessary to fix the bolt head with an auxiliary tool, and then use an auxiliary tool to tighten the nut, or need to use an auxiliary tool to fix the nut, and then use a tool to tighten the bolt head. Tighten to achieve the tightening of the bolts

That is to say, to realize the fastening of the bolt, one end of the bolt needs to be fixed and the other end should be tightened at the same time. If the connected parts have a large area and a thick thickness, that is, when the length of the threaded rod is long, two people need to work at the same time, which is time-consuming, laborious and laborious. High strength, especially in factories that require bolts to assemble parts in mass production, not only the production efficiency is low, but also the cost of human resources is high; if the bolts are placed in the through holes of the connecting parts, due to the limitation of space or the structure of the connecting parts, the bolt head may Impossible or difficult to insert tools, thereby affecting the tightening of bolts, thereby affecting the orderly operation of work
