Abstract
The utility model discloses a kind of lock bolt, comprise bolt head, with the integrated screw rod of bolt head, the joining portion of bolt head and screw rod is a locking plane, the other end at bolt head forms a screw concentric with described screw rod, in described locking plane, around screw rod center line, be interval with many grooves that raise up.By having groove in locking planar design, increased the frictional force of locking surface, shell fragment effect can be played in groove road, strengthen elasticity, screw rod can not ruptured in the process of locking, after lock bolt locking, can increase the anti-twisted power of lock of moving back, can stripped thread after lock bolt locking, increase skid resistance, thereby while having prevented other member in unscrewing inner bolt hole, lock bolt body can not be unscrewed.
Description
Technical field
The utility model relates to fastening piece, is specifically related to a kind of lock bolt.
Background technique
In the prior art, have a kind of for the lock bolt on computer product, as shown in Figure 1, Figure 2 described in, by bolt head 2 with together with the screw rod of moulding form, on bolt head 2, also form an inner bolt hole, this inner bolt hole is used for being connected with other member, as: the members such as VGA line, various datawires; The joining portion of bolt head 2 and screw rod has a locking plane 1, screw rod is screwed into after the screw of machine, relying on locking plane 1 and the plane of machine to lock, is smooth plane contact between the two, and frictional force is little, because the member being connected on inner bolt hole is understood the frequent disassembling section of carrying out, in unloading process, because the frictional force of locking plane 1 is little, can screw rod be unscrewed in the screw from machine together simultaneously, at this moment again tighten again screw rod, to use, make troubles.
Model utility content
The purpose of this utility model is: the above-mentioned defect for prior art, a kind of lock bolt is provided, and when other member of dismounting, can not become flexible yet.
A kind of lock bolt is provided, comprise bolt head, with the integrated screw rod of bolt head, the joining portion of bolt head and screw rod is a locking plane, the other end of bolt head form one with the screw of described screw coaxial, in described locking plane, around center line, be interval with many grooves that raise up.
In above-mentioned lock bolt, in described locking plane, be provided with 10-50 bar groove.
In above-mentioned lock bolt, in described locking plane, be provided with 10-30 bar groove.
The utlity model has following advantage: by having groove in locking planar design, increased the frictional force of locking surface, shell fragment effect can be played in groove road, strengthen elasticity, screw rod can not ruptured in the process of locking, after lock bolt locking, can increase the anti-twisted power of lock of moving back, can stripped thread after lock bolt locking, increase skid resistance, thereby while having prevented other member in unscrewing inner bolt hole, lock bolt body can not be unscrewed.

Fig. 1 is existing lock bolt structural front view;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the utility model structural front view;
Fig. 4 is the sectional view of Fig. 3;
Fig. 5 is the left view of Fig. 3.
Embodiment
Shown in ginseng Fig. 3-Fig. 5; Design a kind of lock bolt, be provided with bolt head 4, with the integrated screw rod 5 of bolt head 4, bolt head 4 is locking planes 3 with the joining portion of screw rod 5, the other end at bolt head 4 forms a screw 6 concentric with described screw rod 5, in described locking plane 3, around screw rod center line, be interval with many grooves that raise up 7.
In above-mentioned lock bolt, 10-50 bar groove 7 can be set in described locking plane 3.
In above-mentioned lock bolt, can as required, 10-30 bar groove 7 be set in described locking plane 3.
In above-mentioned lock bolt, bolt head 4 is hexagonal structure, is convenient to tighten, and also can adopt other shape, as circle.
Groove 7 in locking plane 3, increased the frictional force of locking surface 3 with other parts, shell fragment effect can be played in groove road, strengthen elasticity, screw rod can not ruptured in the process of locking, after lock bolt locking, can increase the anti-twisted power of lock of moving back, can stripped thread after lock bolt, increase skid resistance, in the time of can preventing other member in unscrewing inner bolt hole, lock bolt body can not be unscrewed.
Claims (4)
