Description

Screwed lock and its special spanner

Technical field

The utility model is related to burglary-resisting installations, and in particular to a kind of screwed lock for preventing the equipment such as automobile storage battery stolen and Special spanner.

Background technology

In some countries, automobile storage battery and automobile spare tire are stolen event frequent occurrence, and loss is serious.To prevent equipment quilt It steals, there are also anti-theft bolt appearances at present, though there is certain anti-theft feature, it is complicated, it is of high cost, cause price It is high.

Invention content

In view of the shortcomings of the prior art, the utility model innovation provide it is a kind of it is simple in structure, manufacturing cost is low Screwed lock and screwed lock special spanner.The screwed lock includes body and can be in and cover internal core, it is characterised in that：Institute Stating body bottom, there is the bearing edge that can support core extended to center, the core to have screw hole, the core spiral shell Anisotropic tooth socket is equipped with above hole.

Screwed lock special spanner includes mobile jib, and the lower end of the mobile jib is equipped with the anisotropic tooth to match with anisotropic tooth socket.

It is transversely provided with through-hole on the mobile jib, cross bar is equipped in the through-hole.

According to a kind of screwed lock provided by the utility model, it is located on screw by the cooperation of body and core, makes screw On nut can not be screwed out, screwed lock could can only be opened by screwed lock special spanner, this screwed lock have structure Simply, the advantages such as low cost.

Description of the drawings

Fig. 2 is the sectional view of the utility model；

Fig. 3 is the usage state diagram of the utility model.

Specific implementation mode

As shown in Figure 1, this screwed lock includes body 1 and the core that can be in body 12, as shown in Fig. 2, set After there is 1 bottom of body the bearing edge 10 extended to center, core 2 to be in body 1, core is just supported by bearing edge 10 There is screw hole 20,2 screw hole of core, 20 top to be equipped with anisotropic tooth socket 21 for body 2, core 2.As shown in figure 3, in use, first by nut 6 It is screwed on screw 5, then body 1 is sleeved on screw 5, core 2 is then passed through by 20 spiral shell of screw hole by screwed lock special spanner Line is connected on lead screw 5, and core 2 is made to be completely in body 1, and such human hand or general purpose tool can not just back-out core 2, Thus the technique effect for preventing nut 6 to be screwed out is played；It, can only since 2 screw hole of core, 20 top is equipped with anisotropic tooth socket 21 Core could be back-outed by the spanner of the anisotropic tooth 30 with matching opposite sex tooth socket 21.

For this purpose, the utility model additionally provides a kind of screwed lock special spanner comprising there is mobile jib 3, the lower end of mobile jib 3 to set There is the anisotropic tooth 30 to match with anisotropic tooth socket 21.Using this screwed lock special spanner, core 2 can be twisted from screw 5 Go out；In addition, rotation core 2 and convenient for collecting for convenience, the utility model is transversely provided with through-hole on mobile jib 3, in through-hole Equipped with cross bar 4.In use, cross bar 4 is located at across through-hole on mobile jib 3, as long as pulling cross bar 4 in this way it become convenient substantially that by core Body 2, which is back-outed, to be come, and due to detachable, the storage of screwed lock special spanner is also more convenient.
