In the present utility model, as shown in fig. 1-2, there is provided a radiation protection door lock, comprising a lock base, the lock base comprises a base body 1, a lock tongue 2 mounted on the base body 1, the lock base is provided with a driving hole 3, and the radiation protection door lock comprises: an outer end cap 4 having an outer mounting hole 5, the outer end cap 4 being arranged as a radiation-proof outer end cap 4; an inner end cover 6, which is provided with an inner mounting hole 7, wherein the inner end cover 6 is arranged as an anti-radiation inner end cover 6, a mounting space for mounting the lock seat is formed between the outer end cover 4 and the inner end cover 6, and projections of the outer mounting hole 5 and the inner mounting hole 7 are staggered; the unlocking block 8 is rotatably arranged in the driving hole 3, and the unlocking block 8 can be rotatably switched between an unlocking position and a locking position; the inner end of the outer lock cylinder 9 is arranged on the lock seat, the outer end extends to the outer mounting hole 5, and a rotor of the outer lock cylinder 9 is in transmission connection with the unlocking block 8; the inner lock part 10, the inner lock part 10 comprises a rotating rod 11 which is rotatably arranged and a driving part which can drive the rotating rod 11 to rotate, the rotating rod 11 is in transmission connection with the unlocking block 8, and the driving part extends to the inner mounting hole 7.

When the door lock is used, the lock seat is arranged in the mounting groove of the door body, and the inner end cover 6 and the outer end cover 4 are respectively arranged on the door body. The inner end cover 6 and the outer end cover 4 are both arranged in a radiation-proof structure, so that radiation leakage can be prevented, and the inner mounting holes 7 and the outer mounting holes 5 are arranged in a staggered manner, so that the outer lock cylinder 9 and the inner lock part 10 can be prevented from being directly communicated with leaked radiation.

The unlocking block 8 is arranged in an optimized mode based on the existing lock seat structure, so that the unlocking block 8 rotates to switch between the unlocking position and the unlocking position, and the unlocking block 8 drives the lock tongue 2 to unlock. Therefore, the staggered arrangement between the inner lock part 10 and the outer lock cylinder 9 can be realized by arranging the transmission structure of the unlocking block 8 and the outer lock cylinder 9 and the transmission structure of the unlocking block 8 and the inner lock part 10, so that the staggered arrangement of the inner mounting hole 7 and the outer mounting hole 5 is further adapted.

Therefore, the lock seat structure can be improved in some embodiments without or less, the realization setting of the transmission structure of the unlocking block 8, the outer lock cylinder 9 and the inner lock part 10 is relatively simple, and the research and development and innovation production cost of the lock seat are reduced. The unlocking structure of the unlocking block can refer to the unlocking block structure connected with the existing door lock core.

As a preferred embodiment, for the arrangement of the inner lock part 10, more specifically, the inner lock part 10 is arranged as an inner lock cylinder, the rotor of which forms the rotating rod 11, and the outer end of which forms the unlocking block 8. Thus, the inner lock part 10 can be unlocked by a key, and locking and unlocking of the door lock can be realized.

Or in an alternative embodiment, the inner locking part 10 may be provided as an unlocking lever. The unlocking rod can adopt the existing complete unlocking rod structure, or directly adopts a single rod-shaped structure, and extends out of the inner mounting hole 7 from the unlocking block 8.

In the illustrated embodiment, a further advantageous arrangement consists in that the rotary lever 11 of the inner lock 10 is connected coaxially to the unlocking block 8.

As shown, the inner lock part 10 is coaxially connected to the unlocking block 8, i.e. the inner mounting hole 7 is substantially coaxial with the drive hole 3, in which case the outer cylinder 9 is offset from the drive hole 3. The transmission structure between the inner lock part 10 and the unlocking block 8 can be simplified by directly connecting the inner lock part 10 and the unlocking block 8.

In the illustrated embodiment, as shown in the figure, for the installation mode of the inner lock part 10, more specifically, the rotating rod 11 of the inner lock part is provided with a slot 14, the unlocking block 8 is provided with a rotating shaft 18 positioned and inserted in the slot 14, the section of the slot 14 is non-circular, and the section of the end part of the rotating shaft 18 is non-circular (such as cross-shaped section), so that the rotating rod 11 of the inner lock part 10 and the unlocking block 8 are coaxially connected. In the illustrated embodiment, the inner lock part 10 is provided as an inner cylinder, the bottom of which extends to the inside of the housing 1 and is fixed to the housing 1 by a screw 15 of the housing 1 at one side of the locking tongue 2. As shown in fig. 2, the broken line circle of the inner lock portion is the fixing position of the screw 15.

For alternative embodiments, the inner locking part 10 can also be offset from the drive hole 3, i.e. the inner locking part 10 is in driving connection with the unlocking block 8 by means of an external transmission, such as a gear transmission.

In the illustrated embodiment, the unlocking block 8 is in geared connection with the rotor of the outer cylinder 9, as shown in the drawing. Through gear connection to this makes outer lock core 9 rotate and unlocking block 8 rotate more accurate.

Or the unlocking block 8 is connected with the rotor of the outer lock cylinder 9 through chain transmission. Through chain drive connection, this is applicable to the embodiment that the offset distance is great between outer lock core 9 and unlocking piece 8.

In the illustrated embodiment, for the gear transmission structure between the outer lock cylinder 9 and the unlocking block 8, more specifically, the rotor of the outer lock cylinder 9 is provided with a first gear 12, the unlocking block 8 is provided with a second gear 13 at the end facing the outer end cap 4, and the first gear 12 is meshed with the second gear 13.

The manner of gear engagement between the outer lock cylinder 9 and the unlocking block 8 is not limited to the two-gear manner shown in the figures, but in alternative embodiments more than two gears may be used. The radiation protection effect can be further improved by increasing the span between the first gear 12 and the second gear 13 to accommodate the increase in the projection distance between the outer mounting hole 5 and the driving hole 3.

Referring to the arrangement of the gears in the figures, the outer lock cylinder 9 and the unlocking block 8 adopt a chain transmission mode, which is taken as an exemplary illustration, the first gear 12 and the second gear 13 can be respectively arranged as chain wheels, and chain transmission is arranged between the two chain wheels, at this time, the projection distance between the outer mounting hole 5 and the driving hole 3 can be adaptively increased by increasing the span between the two chain wheels, so that the radiation protection effect is further improved.

In the illustrated embodiment, the first gear 12 is arranged on the side of the second gear 13 facing the bolt 2; the outer lock cylinder 9 is provided with a mounting part 901 extending into the base body 1, a screw 15 is arranged on one side of the base body 1, where the lock tongue 2 extends out, and the screw 15 is fixed on the mounting part 901.

By so doing, as shown, the outer cylinder 9 can be easily installed.

With respect to the construction of the outer end cap 4 and the inner end cap 6, in the illustrated embodiment, more specifically, the inner surface of the outer end cap 4 is provided with an outer lead layer 16 and the inner surface of the inner end cap 6 is provided with an inner lead layer 17.

Or lead layers can be synchronously attached to the side surfaces of the base body 1 so as to further improve the protection effect.

In this specification, each embodiment is described in a progressive manner, and identical and similar parts of each embodiment are all referred to each other, and each embodiment mainly describes differences from other embodiments. In particular, for system embodiments, since they are substantially similar to method embodiments, the description is relatively simple, as relevant to see a section of the description of method embodiments.
