Abstract
The utility model discloses a through-bolt fastening device for a sealing nut. According to the through-bolt fastening device, a screw hole is formed in a hole bolt, and a fastening sleeve head is arranged on the rear end part of the hole bolt. The through-bolt fastening device is characterized in that: an adjustable wrench tool can be sleeved in the fastening sleeve, so that a bolt can be screwed in the sealed hole bolt. The through-bolt fastening device can be suitable for occasions of the short-distance parallel fastening and vertical fastening of devices, and the original through-hole screw cap is replaced completely; and the through-bolt fastening device is not rusted when used outdoors for a long time, so the defects of difficulty in disassembly, the delay of construction period and high possibility of unpredictable safety accidents due to rusting in the conventional nut are overcome completely.
Description
Technical fieldThe utility model relates to fastening piece, directly relates to sealing nut and wears bolt formula fastening device, is specially adapted to open-air fastening use.
Background techniqueExisting indoorly, outdoor tightening up equipment and utensil all must use the straight-bar bolts and nuts that it is tightened up, no matter use conventional screw also to be to use other special-shaped screw, all is boundly to use nut to twist on jail and the bolt could to realize.Though it is convenient and practical but also have certain drawback that people also send out the existing conventional screw of rule in long-term the use: when outdoor equipment and utensil are using certain hour or safeguarding when changing; Certainly will unclamp and back out tightening up nut; Because promptly corrosion firmly is on bolt naturally for the long-term erosion of the long-term wind-engaging of bolt, rain and Exposure to Sunlight, nut, the spanner of use nutting is taken great pains also can not be with its loosening turning on; At this moment will use cutting tool to accomplish; More difficult when particularly power industry is removed equipment on bar, because operating conditions is restricted on the bar, regular meeting is because of handling the generation that unpredictable dangerous accident can appear in the corrosion bolt in the time of also.
Summary of the inventionThe purpose of the utility model will provide a kind of sealing nut to wear bolt formula fastening device exactly; It can solve effectively: when outdoor equipment and utensil are using certain hour or safeguarding when changing; Certainly will unclamp and back out tightening up nut; Because promptly corrosion firmly is on bolt naturally for the long-term erosion of the long-term wind-engaging of bolt, rain and Exposure to Sunlight, nut, the spanner of use nutting is taken great pains also can not be with its loosening turning on; At this moment will use cutting tool to accomplish; More difficult when particularly power industry is removed equipment on bar, because operating conditions is restricted on the bar, regular meeting is because of handling the serious drawback that the generation of unpredictable dangerous accident can appear in the corrosion bolt in the time of also.
The purpose of the utility model is achieved in that sealing nut wears bolt formula fastening device, has the hole bolt, in the bolt of said hole a hole is set, and hole bolt rearward end setting is put fastening pullover.
The utility model has been owing to adopted a hole has been set in the bolt of hole, and the bolt rearward end is provided with fastening pulloverly in the hole, and its characteristics are: can use pull the instrument of twisting be inserted in fastening pullover on, realization can be twisted the Kong Shuanzhong with sealing with bolt.
Use the utility model; In the parallel fastening and vertical fastening occasion of device short distance; Substituted original through hole nut fully; The long-term use corrosion can not occur in the open, overcome existing nut fully and has been difficult for the drawback removing, be prone to incur loss through delay the duration and also be prone to occur unpredictable dangerous accident after because of corrosion.
Description of drawingsAccompanying drawing is the structure principle chart that the utility model sealing nut is worn bolt formula fastening device, below in conjunction with accompanying drawing the utility model is described further.
EmbodimentAccompanying drawing shows the structure of the utility model, and a hole 2 is set in the hole bolt 1, and bolt 1 rearward end in hole is provided with fastening pullover 3.
The using process of the utility model is: at first real bolt 5 is penetrated the fixed hole intraocular of fixed equipment and utensil (indicating), and then be inserted in can directly twist extremely and in the hole bolt 1 hole 2 is set behind the red steel plate washer 4 and can accomplish terminal operation.(tightening up sealing and waterproof that the red steel plate washer 4 in back also can be used as two keys).
