Description

Split type key

(one) technical field

The utility model relates to split type key, is a kind of key of cross spoon bar.

(two) background technology

Type of key is various, though all kinds of key external form is different, generally all is easy to duplicate, and causes stolen incident to happen occasionally because of key is replicated.Be to improve security, some has the confidential places of emphasis such as safety cabinet, reference room, national treasury of valuables two locks is installed simultaneously, and key is taken care of respectively by two people, and two people show up simultaneously and unblank just can open the door afterwards.Shortcoming is that two locks must be installed, and is cumbersome.

(three) summary of the invention

The purpose of this utility model provides a kind of split type key, makes the key partable, is taken care of respectively by two people after the split, just becomes the complete key that can unblank after closing up, and realizes that two people run the antitheft purpose of a lock jointly.

But this Split key is made up of main spoon and the secondary spoon of split, main spoon contains spoon handle and spoon bar, two side planes of spoon bar have longitudinal fluting, front end has one section opening socket forward, the spoon bar of secondary spoon is provided with vertical socket that the longitudinal fluting with main spoon is interlocked, and this socket is to after-opening, the vertical snapping of groove of the socket of secondary spoon and main spoon, the front end of secondary spoon embeds in the socket of main spoon front end, and being combined into the cross section is cross spoon bar.

Can be taken care of respectively by two people after above-mentioned main spoon and the split of secondary spoon, the two just can be unblanked after being fastened into a complete cross key.For ease of carrying and use, secondary spoon also can be provided with a spoon handle, this spoon handle contain can with the spoon of main spoon the open slot that is halved together.In two spoons of vertical snapping processes, when the socket of secondary spoon advanced backward along main spoon groove, the spoon of main spoon was in the open slot that also is embedded into secondary spoon spoon handle, and the two becomes one.

The utility model spoon bar is embedded with and corresponding several magnetic pillars of the magnetic bullet of lock core.When unblanking, this key also utilizes different in nature suction or the same sex thrust of magnetic except with the highly different crown ejection lock core marbles, by the magnetic pillar magnetic bullet corresponding in the lock core is moved, and reaches certain levelling height.

As mentioned above, the utility model can make a key split become major and minor two keys, is taken care of respectively by two people, realizes that two people run the antitheft purpose of a lock jointly.Be embedded in the magnetic pillar in spoon bar owing to be recessive, be difficult to definite accurate position that it is buried underground on the surface, so this key can be prevented copying safety and reliability.

(four) description of drawings

Fig. 1 is main spoon structural representation; Fig. 2 is secondary spoon structural representation.

Fig. 3 is the overall structure schematic diagram that major and minor two key rings connect the cross key after the combination.

Fig. 4 is the A-A sectional drawing; Fig. 5 is the B-B sectional drawing.

(five) specific embodiment

This Split key is pegged graft by main spoon shown in Figure 1 and secondary spoon shown in Figure 2 and is combined, and the key after the combination as shown in Figure 3.

As seen from Figure 1, the spoon bar 2 of main spoon has longitudinal fluting 3, and this groove is provided with (cross-section structure of main spoon 2 in referring to Fig. 4) in main spoon both sides plane symmetry, and the front end of spoon bar is the socket 1 to open front, and the rear end is provided with spoon 4.Be embedded with magnetic pillar 9 in the spoon bar.

As shown in Figure 2, the spoon bar 5 of secondary spoon has aft-opening vertical socket 6, and spoon is provided with open slot 8 to 7.

When the plane of two spoons of bars of the secondary spoon of Fig. 1 master's spoon and Fig. 2 each other vertically vertically during snapping, secondary spoon is held propelling (be expressed as among the figure from left to right and advance) by socket 6 from front to back along the grooves on two sides 3 of main spoon, finally being combined into the cross section is criss-cross complete key, the front end (being illustrated left end) of secondary spoon embeds in the socket 1 of main spoon front end simultaneously, and the spoon of main spoon is partially submerged into the spoon of secondary spoon to 4 in 7 the open slot 8.Fig. 3 is the overall structure figure of the utility model Split key, and the spoon bar plane of main spoon 2 and secondary spoon 5 is orthogonal among the figure, vertically fastens (the transversal Fig. 4 that meets personally), and as seen from Figure 5, the spoon of secondary spoon is 7 bathtub construction, and the spoon of main spoon is partially submerged into 4 in this groove 8.Magnetic pillar 9 is corresponding with the magnetic bullet position in the lock core, according to the number and the position relative set of magnetic bullet in the lock core.

The spoon of vice spoon has wire rope handling aperture 7-1 to 7 among Fig. 2,3,5.

Claims (5)
