Abstract
The utility model discloses a screw locking device which comprises a lock base (1) and a lock bolt (2). The screw locking device is characterized in that a screwed groove (3) is arranged on the lock bolt (2); a keyhole (4) is arranged on the lock base (1); and a boss (5) which can be blocked in the groove (3) is arranged in the keyhole (4). Compared with the prior art, the screw locking device provided by the utility model can achieve fast locking and has excellent anti-loose performance; besides, the screw locking device can be assembled and demounted easily and conveniently; and with reliable connection, the screw locking device can be widely used in the mechanical field and has good application prospect.
Description
Technical field
The utility model relates to a kind of screw locking device, belongs to technical field of fastening.
Background technique
Bolt, nut are to use fastening piece very widely, but it has himself inevitable shortcoming: 1, be given a shock in long-term the use, bolt and nut will unclamp gradually and come off, and its connection does not possess anti-loosening performance; Must follow screw thread rotation when 2, installing, be not very quick; 3, often dismounting can make thread damage, so that can not use; 4, bolt and nut mostly is irony, and long-term use is met water unavoidably, made moist, gets rusty, and causes bolt and nut to disassemble.
The model utility content
The purpose of this utility model is: provide a kind of and can lock fast, have good anti-loosening performance and installation, easy removal, the reliable screw locking device of connection, to overcome the deficiencies in the prior art.
The utility model is to constitute like this:
It comprises lock and pinning, and pinning is provided with helical groove; Lock is provided with keyhole, is provided with the boss that can snap in the groove in keyhole.
Above-mentioned screw locking device is provided with the pinning head on the pinning top; Being outside equipped with the nail cover at pinning, closes up in nail cover lower end, and closing in place diameter is less than the diameter of pinning head; Pinning is provided with spring, and spring is between pinning head and nail cover.
Aforesaid screw locking device is provided with the instrument connection mouth in the pinning head top; The nail cover is provided with the through hole of the instrument that can insert.
Aforesaid screw locking device, the instrument connection mouth of pinning head top are square or orthohexagonal counterbore or are the rim of the mouth of rising that can insert quincunx or flat degree of lip-rounding bottle opener.
Owing to adopted technique scheme, there is not screw thread on the pinning, can directly insert keyhole, much more simple and convenient than the installation that is threaded.Boss can screw in groove, has played the effect that the restriction pinning moves along axial direction in lock.The spring of installing on the pinning has certain tensioning when pinning inserts keyhole, promptly pinning is had an active force that makes progress, this active force makes boss tightly block groove, has limited the rotation of pinning, make to the utlity model has good anti-loosening performance, thereby realize connecting reliably.When the utility model is installed, screw-driver is inserted the instrument connection mouth, pinning is pressed into keyhole, make boss screw in groove, unclamp screw-driver and get final product; During dismounting the utility model, screw-driver is inserted the instrument connection mouth, press down pinning slightly, the rotation pinning makes boss screw out groove, unclamps screw-driver and gets final product.Screw locking device of the present utility model can be locked fast, has good anti-loosening performance; Installation, easy removal connect reliably, can be widely used in mechanical industry, and good prospects for application is arranged.
Description of drawings
Accompanying drawing 1 is a main TV structure schematic representation of the present utility model.
Embodiment
Embodiment of the present utility model: screw locking device of the present utility model, make as follows: pinning 2 and nail cover 7 can adopt better rigidity metals such as iron, stainless steel to make, and spring 8 can use the finished product of buying on the market.On pinning 2, produce helical groove 3, produce pinning head 6 on pinning 2 tops, produce at pinning head 6 tops square or orthohexagonal counterbore or for the rim of the mouth that can insert quincunx or flat degree of lip-rounding bottle opener as instrument connection mouth 9, spring 8 is enclosed within on the pinning 2.To follow closely cover 7 and be made into tubbiness, produce the through hole 10 of the instrument that can insert thereon; To follow closely cover 7 and be enclosed within on the pinning 2, its lower end riveted joint is closed up, closing in place diameter makes spring 8 between pinning head 6 and nail cover 7 less than the diameter of pinning head 6.Lock 1 can be produced on the body or big shaped steel body structure spare on, on lock 1, produce keyhole 4, in keyhole 4, produce the boss 5 that can snap in the groove 3.
