Description

The hollow lock tube that protects

Technical field:

The utility model relates to a kind of being widely used on U-shaped lock and the padlock, prevents from directly to insert the hollow lock tube that protects that lockhole destroys core with any instrument.

Background technology:

As everyone knows, at present, outside the lockhole of the various locks of selling on the market all is exposed to, lock core is come into plain view, can easily lock be opened and steal bicycle, electric bicycle or motorcycle etc. with master key or reamer etc.

Summary of the invention:

Main purpose of the present utility model is to overcome above deficiency and provides a kind of lockhole, lock core not to expose, adopt outstanding key antitheft be used for the hollow lock tube that protects on U-shaped lock and the padlock.

The technical scheme that its technical problem that solves the utility model adopts is: it is welded into hollow casing shape by steel plate, middle part in the cavity has dividing plate 2, have circular hole 5 on the dividing plate 2, dividing plate 2 constitutes through hole 4 with a hollow side protecting lock tube 1, and the hollow other end that protects lock tube 1 has elongated slot 3.

The utility model can also adopt following technical measures:

Described dividing plate (2) can not wanted yet;

Described elongated slot (3) can also be opened the font of falling L groove at the hollow upper surface that protects lock tube 1.

Advantage and the good effect that the utlity model has are: be fixed with on simple in structure, easy for installation, the key 7 curve handle 6, lockhole by hidden, can't know lock core structure, therefore, master key or reamer etc. can not directly insert in the lockhole, and power is pushed lock core aside ingeniously, and it is low to have increased the safety of lock, processing easily, cost.

Among Fig. 1: 1. the hollow lock tube 1 that protects, 2. dividing plate, 3. elongated slot, 4. through hole, 5. circular hole, 6. handle, 7. key, 8. tapered end, 9. lock thick stick, 10. screw.

The specific embodiment:

For further understanding summary of the invention characteristics of the present utility model and effect following examples for example now, and conjunction with figs. is described in detail as follows, and sees also Fig. 1-Fig. 4.

As shown in Figure 1 and Figure 2: the hollow lock tube 1 that protects is made up of dividing plate 2, elongated slot 3, through hole 4 and circular hole 5, the hollow lock tube 1 usefulness steel plate that protects is welded into casing shape, middle part in the cavity has dividing plate 2, have circular hole 5 on the dividing plate 2, dividing plate 2 and the hollow middle formation through hole 4 that protects a side of lock tube 1, tapered end 8 penetrates from through hole 4, and the hollow other end that protects lock tube 1 has elongated slot 3, elongated slot 3 can also be made the font of falling L elongated slot 3 as shown in Figure 4, and dividing plate 2 can not wanted yet sometimes.

During use, at first tapered end 8 is inserted in the hollow through hole 4 that protects lock tube 1, and with screw 10 with hollow lock tube 1 and tapered end 8 diebacks of protecting, then, in the hole at tapered end 8 two ends, penetrate U-shaped and lock thick stick 9, at this moment, lock is lockable; When unblanking, the handle 6 of hand-held key 7 as shown in Figure 3 by in the circular hole 5 that inserts in the elongated slot 3 on the dividing plate 2, behind the aligning lockhole, turns key 7 key 7 and can open tapered end 8.Usually, having the hollow U-shaped lock that protects lock tube 1 is that fixtures such as car and iron railing or trunk are locked together, and to strengthen the safety of car, because of the hollow lockhole that protects lock tube 1 does not expose, simultaneously, also cannot see the structure of lock core, so can't destroy.

Its advantage is: simple in structure, easy for installation, safe and reliable, cost is low.
