Abstract

The utility model provides a curved bar formula key. The handle is connected with the upper end of pivot, and the lower end of pivot is connected with the left end head of rocking arm, and the right -hand member head and the spoon pole upper end of rocking arm are connected, and bent rod -type structure is constituteed jointly to pivot, rocking arm and spoon pole. Fore -and -aft guide way has been seted up to medial surface along the spoon pole, and the vice lockhole of a plurality of has been seted up to the order from the top down in the guide way. Following spoon right -hand member of pole lateral surface and having seted up a plurality of master lock hole from the top down in proper order, seted up the horizontal deliver groove of a plurality of from the top down in proper order along the left end of spoon pole lateral surface, each deliver groove communicates with each master lock hole respectively. During the use, insert the spoon pole keyhole of tapered end, when pellet shot from a slingshot in vice lockhole when the spoon pole medial surface on and the tapered end in the lock core cooperated, the handle can be through pivot and rocking arm rotation lock core. At the rotatory in -process of lock core, when the master lock hole on spoon pole lateral surface cooperated with the pellet shot from a slingshot in the tapered end, the lock core could continue the rotation and consequently open the tool to lock.

Description

Curved bar structures key

Technical field

This utility model relates to a kind of security protection key, especially can by key being arranged to curved bar structures structure, thus improving the curved bar structures key of its security protection performance.

Background technology

At present, known key is the structure of straight-bar type, and therefore its keyhole of existing tapered end is also straight hole type structure, owing to the keyhole of straight hole type facilitates use instrument to carry out pirate of the open, so its security protection poor-performing of the key of straight-bar type.

Summary of the invention

In order to overcome the deficiency of existing its security protection poor-performing of straight-bar type key, this utility model provides a kind of curved bar structures key, this curved bar structures key can by key being arranged to curved bar structures structure, thus improving its security protection performance.

This utility model solves the technical scheme is that this utility model of its technical problem and includes handle, rotating shaft, spoon bar, extradition groove, rocking arm, gathering sill, secondary lockhole and main lockhole. Handle is connected with the upper end of rotating shaft, rotating shaft is cylindrical structural, the lower end of rotating shaft is connected with the left end head of rocking arm; rocking arm is the Rectangular Plate Structure of horizontally set; spoon bar is disposed longitudinally on the lower section of rocking arm; the upper end of spoon bar is connected with the right end of rocking arm, and rotating shaft, rocking arm and spoon bar collectively constitute curved bar structures structure. Spoon bar is rectangular shaft structure, and the lateral surface of spoon bar is arcwall face structure. Medial surface along spoon bar offers gathering sill from the top down, and gathering sill is strip groove structure, and in gathering sill, order offers several secondary lockholes from the top down. Right-hand member order from the top down along spoon bar lateral surface offers several main lockholes, and the left end order from the top down along spoon bar lateral surface offers several extradition grooves, and extradition groove is horizontal arc groove structure, and each extradition groove connects with each main lockhole respectively. Each main lockhole on spoon bar lateral surface is corresponding with each the secondary lockhole on spoon bar medial surface respectively.

During use, being inserted by spoon bar in the keyhole of tapered end upper lock core, when the secondary lockhole on spoon bar medial surface coordinates with the pellet in tapered end upper lock core, handle can rotate lock core by rotating shaft and rocking arm. In the process that spoon bar and lock core rotate jointly, when the main lockhole on spoon bar lateral surface is touched the pellet in tapered end and coordinated with pellet by extradition groove, lock core just can be rotated further and therefore open lockset.

The beneficial effects of the utility model are, by key is arranged to curved bar structures structure, thus improving its security protection performance.

Detailed description of the invention

In Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, handle 1 is connected with the upper end of rotating shaft 2, rotating shaft 2 is cylindrical structural, the lower end of rotating shaft 2 is connected with the left end head of Rocker arm 5; Rocker arm 5 is the Rectangular Plate Structure of horizontally set; spoon bar 3 is disposed longitudinally on the lower section of Rocker arm 5, and the upper end of spoon bar 3 is connected with the right end of Rocker arm 5, and rotating shaft 2, Rocker arm 5 and spoon bar 3 collectively constitute curved bar structures structure. Spoon bar 3 is rectangular shaft structure, and the lateral surface of spoon bar 3 is arcwall face structure. Medial surface along spoon bar 3 offers gathering sill 6 from the top down, and gathering sill 6 is strip groove structure, and in gathering sill 6, order offers several secondary lockholes 7 from the top down. Right-hand member order from the top down along spoon bar 3 lateral surface offers several main lockholes 8, left end order from the top down along spoon bar 3 lateral surface offers several extradition grooves 4, extradition groove 4 is horizontal arc groove structure, and each extradition groove 4 connects with each main lockhole 8 respectively. Each main lockhole 8 on spoon bar 3 lateral surface is corresponding with each the secondary lockhole 7 on spoon bar 3 medial surface respectively.

During use, being inserted by spoon bar 3 in the keyhole of tapered end upper lock core, when the secondary lockhole 7 on spoon bar 3 medial surface coordinates with the pellet in tapered end upper lock core, handle 1 can rotate lock core by rotating shaft 2 and Rocker arm 5. In the process that spoon bar 3 and lock core rotate jointly, when the main lockhole 8 on spoon bar 3 lateral surface is touched the pellet in tapered end and coordinated with pellet by extradition groove 4, lock core just can be rotated further and therefore open lockset.
