Multifunctional long foundation bolt

Abstract

The invention discloses a multifunctional long foundation bolt. The multifunctional long foundation bolt comprises a deeply-buried portion, a hook and a nut, the deeply-buried portion is provided with a cylindrical head, a neck and a tail, a first external thread is arranged on the head of the deeply-buried portion, the neck of the deeply-buried portion is located between the head and the tail of the deeply-buried portion, a second external thread is arranged on the tail of the deeply-buried portion, a first curved arm and a second curved arm are arranged on the hook and arranged in an L shape, a first internal thread which is matched with the first external thread is arranged at the tail end of the first curved arm, and a second internal thread which is matched with the second external thread is arranged on the nut. By the aid of the method, the multifunctional long foundation bolt integrates a plurality of installation and dismounting functions and is simple to operate, flexible to use, high in tensile bearing capacity and small in occupied space.

Description

technical field [0001] The invention relates to the field of mechanical fixing devices, in particular to a multifunctional long anchor bolt. Background technique [0002] Long anchor bolts are used to fix heavy mechanical equipment with strong vibration and impact during work. Most of the existing long anchor bolts are detachable structures, that is, there are threads on the tail of the buried depth to fix the buried depth and mechanical equipment. , but in order to ensure the friction between the long anchor bolts and the foundation of the mechanical equipment, in order to avoid the damage of the long anchor bolts, and to enable the long anchor bolts to bear a certain tensile bearing capacity, the buried depth and The hook is generally an integrated structure, as a whole, therefore, although the existing long anchor bolts have national standard parts, due to the different structures of the fixed parts of different mechanical equipment, the actual situation is that different...

[0002] Long anchor bolts are used to fix heavy mechanical equipment with strong vibration and impact during work. Most of the existing long anchor bolts are detachable structures, that is, there are threads on the tail of the buried depth to fix the buried depth and mechanical equipment. , but in order to ensure the friction between the long anchor bolts and the foundation of the mechanical equipment, in order to avoid the damage of the long anchor bolts, and to enable the long anchor bolts to bear a certain tensile bearing capacity, the buried depth and The hook is generally an integrated structure, as a whole, therefore, although the existing long anchor bolts have national standard parts, due to the different structures of the fixed parts of different mechanical equipment, the actual situation is that different mechanical equipment uses different Long anchor bolts, most of these long anchor bolts are non-standard parts, which not only increases the cost of long anchor bolts, but also increases their maintenance and replacement costs
