Description

Plumbous equilibrium block fix bolt-unfastening preventing device
Technical field
The utility model relates to a kind of anti-loosening device of bolt, relates in particular to a kind of plumbous equilibrium block fix bolt-unfastening preventing device.
Background technique
Current plumbous equilibrium block means of fixation, adopts bolt directly to install and be fastened in steel part, and because metallic lead intensity is low, easily plastic deformation, causes clamping bolt loosening, even comes off, and causes drive gap vibrations or accident.
Summary of the invention
The technical problems to be solved in the utility model is: directly installs and is fastened in steel part with bolt, and because metallic lead intensity is low, easily plastic deformation, cause clamping bolt loosening, even come off, cause drive gap vibrations or accident, a kind of plumbous equilibrium block fix bolt-unfastening preventing device is provided.
In order to overcome the defect existing in background technique, the utility model solves the technological scheme that its technical problem adopts: this plumbous equilibrium block fix bolt-unfastening preventing device comprises assembly, assembly is provided with plumbous equilibrium block, connecting bolt on described plumbous equilibrium block, described bolt top is provided with positioning pin hole, described positioning pin hole inner side is provided with 2 positioning holes, places spring holder in described positioning hole.
According to another embodiment of the invention, further comprise that described plumbous equilibrium block is provided with the hole corresponding with positioning hole with bolt joint.
The beneficial effects of the utility model are: this plumbous equilibrium block fix bolt-unfastening preventing device adopts this structure locking device, can effectively prevent from that clamping bolt from unclamping to come off, and installation, convenient disassembly, cost is low, and reliability is high.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model bolt;
Fig. 3 is the utility model embodiment's structural representation;
Wherein: 1, assembly, 2, plumbous equilibrium block, 3, bolt, 4, spring holder, 5, positioning hole, 6, positioning pin hole, 7, hole.
Embodiment
Shown in Fig. 1 and Fig. 3, figure comprises assembly 1, and assembly 1 is provided with plumbous equilibrium block 2, and connecting bolt 3 on plumbous equilibrium block 2 as shown in Figure 2, is provided with positioning pin hole 6 at bolt 3 tops, and positioning pin hole 6 inner sides are provided with 2 positioning holes 5.The interior placement spring holder 4 of described positioning hole 5.Plumbous equilibrium block 2 is provided with the hole corresponding with positioning hole 57 with bolt 3 joints.
First bolt 3 is carried out to drilling processing hexagonal positioning pin hole 6, with on the fastening plumbous equilibrium block 2 of suitable torque force and assembly 1, adopt power drill on plumbous equilibrium block, to process corresponding 2 holes along 2 positioning holes 5 of 180 degree of bolt on bolt 3.Positioning hole 5 is inserted in spring holder 4 one end, Compress Spring locating stud one side, aim at other one end positioning hole 5, unclamp and insert it into hole 7, by bolt 3 and plumbous equilibrium block 2 positioning hole inner spring locating studs 4, effectively prevent from that clamping bolt rotation from unclamping to come off, as long as dismounting is Compress Spring locating stud, and take out, rotatable clamping bolt, convenient and swift.
