Description

The mechanical code safety lock

This reality is novel to relate to a kind of mechanical code lock.

Lock is as staple, coded lock is good because of its theftproof performance, vi have high safety, selected widely to use by people, mainly contain two types of electronic type and mechanical types on the existing market, the form of product is a lot, announced that at Chinese utility model patent a kind of patent No. is 96201088 " cipher lock ", it is to be provided with to transfer the ink recorder structure in the lock housing body, transfer the interior mechanism of sign indicating number to be fixed on the bolt plate by the bolt plate axle, bolt plate one end is dead bolt fixedly, and the inner lock head handle is connected with tapered end plate stem and interior handle dead man, and outer trick lock is provided with the tapered end dead man and is connected with base plate dead man on the housing base plate, base plate upwards is provided with the lockmaking sheet, bolt plate and dead bolt link both sides are respectively equipped with dead bolt spring and power-assist structure, and this coded lock structure is comparatively complicated, and it is less relatively that the password of lock is counted setting range.

It is a kind of simple in structure that the purpose of this utility model is to provide, and the password number of lock is many, the mechanical type puzzle lock that safety and reliability are high.

In order to achieve the above object, technical solution of the present utility model is: in the lock bottom surface knob is set, egative film is housed on knob, egative film is fixed on the lock bottom surface, prevents that knob from coming off, and is fluted on knob, also be provided with card article, card article fastens the locking bolt that is arranged on lock both sides, bottom surface, and turning knob, card article can make the locking bolt slip stretch out and retraction; Locking bolt is fixed on the lock bottom surface with compressing tablet, is provided with pintle hook lock at the locking bolt of side, and pintle hook lock is used to block locking bolt; Be provided with spring in the middle of knob, withstand being located at the middle cipher chips of locking face, cipher chips is provided with projection, after password is stirred correctly, and dead spring, the projection on the cipher chips blocks the groove on the knob face, and the rotation cipher chips can be opened lock; Be provided with the password tooth outside cipher chips, being provided with more than two sections anodontia section on the password tooth, be used to regulate being distributed in the cipher wheel that the password tooth rim encloses, cipher wheel matches with the password tooth; Connect the cipher wheel sheet under each cipher wheel, the pilot pin on the cipher wheel is fixed on cipher wheel and cipher wheel sheet on the lock bottom surface together, between lock bottom surface and cipher wheel and cipher wheel sheet positioning ball and retainer spring is set; On the cipher wheel sheet, have one section the tooth section arranged, cipher chips be provided with the identical number of wheel number of password the tooth section arranged, cipher chips matches with the cipher wheel sheet, cipher chips and cipher wheel are respectively equipped with scale mark at the rigging position of locking face.

After having adopted such structure, because when opening, at first be that the password tooth is aimed at the regulation scale that is engraved in locking face, the order rotational password takes turns to the regulation scale place that is engraved in locking face in accordance with regulations for the first time, the rotational password tooth is to the scale of regulation again, the password that rotates regulation for the second time takes turns to outside the regulation scale that is engraved in locking face, the rotational password tooth is to the scale of regulation again, rotational password takes turns to the scale place of regulation for the third time, at last cipher chips is rotated the position of regulation, make the projection on the cipher chips aim at the groove that is provided with on the middle knob in lock bottom surface, depress cipher chips, the rotational password sheet drives knob, the knob locking bolt is opened lock, such structure is at the password tooth, and multiple password is set on cipher chips and the cipher wheel, make the password number of lock obtain bigger increase, the safety of lock and reliability improve.

Further specify the utility model below in conjunction with accompanying drawing and concrete embodiment.

Fig. 1 is the sectional view of the safety lock of the utility model mechanical code.

Fig. 2 be Fig. 1 along A-A to view.

Fig. 3 be Fig. 1 along B-B to view.

As Fig. 1, mechanical code safety lock shown in Figure 2 centre on the lock bottom surface is provided with knob 3, egative film 15 is housed on knob 3, egative film 15 is fixed on the lock bottom surface 2, two grooves 18 are arranged on knob 3, on knob, also be provided with two card articles 17, fasten the locking bolt 1 that is arranged on lock both sides, bottom surface respectively, card article is in company with knob, the drive locking bolt slides, realize stretching out and retraction of locking bolt, i.e. the closing and open of lock, compressing tablet 16 is stuck in locking bolt 1 to be locked on the bottom surface, is provided with pintle hook lock 6 at the locking bolt of a side, pintle hook lock pulls out in the gap slot of locking bolt 1 can block locking bolt, be provided with a spring 4 in the knob centre, another part of spring places in the cipher chips 11 of locking face 7 centres, withstands cipher chips 11.As shown in Figure 3, outside cipher chips 11, be provided with password tooth 10, cipher chips is provided with two projections 12, around the password tooth, be furnished with four cipher wheel 9, on password tooth 10, there be three sections anodontia section, anodontia section is used to regulate cipher wheel, cipher wheel 9 matches with password tooth 10, the cipher wheel sheet 14 that reference column 13 connections are arranged in each cipher wheel, the cipher wheel sheet is provided with one section the tooth section, cipher chips 11 is provided with four the tooth section, cipher chips 11 matches with cipher wheel sheet 14, and the pilot pin 13 of cipher wheel is fixed on cipher wheel 9 and cipher wheel sheet 14 on the lock bottom surface 2, is provided with positioning ball 8 and retainer spring 5 between lock bottom surface and cipher wheel 8 and cipher wheel sheet 14, positioning ball 8 places in the groove 19 of lock bottom surface 2, and cipher wheel 9 and password tooth 10 are provided with scale mark on the rigging position of locking face 6.
