Description

A kind of novel ship safety lock

Technical field

The utility model relates to a kind of safety lock, refers in particular to a kind of novel ship safety lock.

Background technology

In prior art, the boats and ships storerooms generally all uses padlock antitheft, yet, because padlock is suspended on door leaf, when the sled padlock, be very easy to find the picking lock fulcrum, be easy to padlock is knocked open.After the ship harbour, the padlock that the boats and ships storerooms often occurs is damaged, and non-ship personnel enter the thing that the storeroom is stolen, and cause unnecessary property loss.

In view of the defects of prior art, the inventor develops a kind of novel ship safety lock that overcomes this defective, and this case produces thus.

Summary of the invention

The novel ship safety lock that provides a kind of safety good and simple in structure is provided the purpose of this utility model.

For reaching above-mentioned purpose, solution of the present utility model is:

A kind of novel ship safety lock comprises fixedly key of pedestal, backing plate, nonstandard bolt and bolt; Pedestal is fixedly mounted on the boats and ships doorframe, and backing plate one end is fixedly connected with pedestal, and the other end is fixedly mounted on door leaf; Nonstandard bolt is comprised of screw rod and nonstandard bolt head, and is screwed onto in pedestal; Bolt fixedly key one end forms the lock core corresponding with nonstandard bolt head shape, and under the use state, lock core inserts nonstandard bolt head.

Further, pedestal is comprised of nut seat and fixed sleeving; Nut seat is fixedly mounted on the boats and ships doorframe, and forms internal thread hole; Fixed sleeving is fixedly mounted on nut seat, and forms inner chamber, forms the tapped through hole corresponding with the nut seat internal thread hole at the bottom of the chamber; Nonstandard bolt is screwed onto in tapped through hole and internal thread hole successively.

Further, nonstandard bolt head shape or be triangle or for pentagon or for hexagon or for semicircle or be rhombus.

After adopting such scheme, the utility model is when locking state, and bolt is the lock core of key fixedly, the nonstandard bolt head of lock core insertion, and rotating bolt fixedly key nonstandard bolt is screwed onto in pedestal, realize locking function.Because being shaped as of nonstandard bolt head is off-gauge, only have adopt the bolt match fixedly key nonstandard bolt could be opened, and when prizing by instrument, can't find again suitable fulcrum, thus the anti-theft security of assurance boats and ships storerooms; Simultaneously, the utility model only need adopt nonstandard bolt and bolt fixedly the cooperation of key can complete locking, its structure is comparatively simple.

The specific embodiment

Below in conjunction with drawings and the specific embodiments, the utility model is described in detail.

Consult Fig. 1 to shown in Figure 9, a kind of novel ship safety lock that the utility model discloses comprises fixedly key 4 of pedestal 1, backing plate 2, nonstandard (non-standard, namely irregular) bolt 3 and bolt.

Pedestal 1 is fixedly mounted on boats and ships doorframe 5, and boats and ships doorframe 5 is fixedly mounted on boats and ships leg 6, and backing plate 2 one ends are fixedly connected with pedestal 1, and the other end is fixedly mounted on door leaf 7.

Nonstandard bolt 3 is comprised of screw rod 31 and nonstandard bolt head 32, and is screwed onto in pedestal 1.Bolt fixedly key 4 one ends forms the lock core 41 corresponding with nonstandard bolt head 32 shapes, and under the use state, lock core 41 inserts nonstandard bolt head 32.As Fig. 8 and shown in Figure 9, bolt fixedly key 4 adopts round steel to make, and also can be made by other material.

For making pedestal quick and easy for installation, pedestal 1 can be comprised of nut seat 11 and fixed sleeving 12.Nut seat 11 is fixedly mounted on boats and ships doorframe 5, and forms internal thread hole 111.Fixed sleeving 12 is fixedly mounted on nut seat 11, and forms inner chamber 121, forms the tapped through hole 122 corresponding with nut seat 11 internal thread holes 111 at the bottom of the chamber.Nonstandard bolt 3 is screwed onto in tapped through hole 122 and internal thread hole 111 successively.

As Figure 6 and Figure 7, nonstandard bolt head 32 shapes can be designed as triangle, and lock core 41 also is set to triangle accordingly.

Nonstandard bolt head 32 shapes also can be designed as pentagon or for hexagon or for semicircle or be rhombus, and are corresponding with it, and lock core 41 also is set to pentagon or for hexagon or for semicircle or be rhombus.

The utility model in use, nut seat 11 is welded on doorframe 5, fixed sleeving 12 is welded on nut seat 11, weld again a backing plate 2 on fixed sleeving 12, and backing plate 2 is welded on door leaf 7, be nonstandard trigonocephalia bolt in the nonstandard bolt 3(of the interior insertion of fixed sleeving 12 the present embodiment), then with bolt fixedly key 4 tighten nonstandard bolt 3, safety lock has just been locked.Open when lock, with bolt fixedly key 4 twist nonstandard trigonocephalia bolt 3, direction with lock on the contrary, can open safety lock.

Key point of the present utility model is: nonstandard bolt head 32 is non-standard shapes, be irregular, only have employing with it corresponding lock core 41 nonstandard bolt 3 could be opened, greatly improve anti-theft security.

The above is only preferred embodiment of the present utility model, is not the restriction to this case design, and all equivalent variations of doing according to the design key of this case all fall into the protection domain of this case.
