Embodiment 1

[0033] Such as Figure 1 to Figure 5 As shown, a screw key 100 includes a key head 110, a key handle 120, a connecting pin 130, and a ball 140. The key head 110 is a hollow structure, which includes a helical section 112 with a thread structure, and is connected to the helical section 112. The installation section 114, the inner surface of the helical section 112 is provided with a hole groove 1122, the outer surface of the installation section 114 is provided with a first rolling groove 1142, and the end of the installation section 114 away from the helical section 112 is provided with a limiting groove 1144, the connecting pin 130 includes an inserting section 132 and a snap-in section 134 connected to the inserting section 132, the inserting section 132 is provided with a limiting portion 1322 near the outer surface of the snap-in section 134, the insertion of the connecting pin 130 The segment 132 is installed in the key head 110, the limiting part 1322 is stuck on the lim...

Embodiment 2

[0038] This embodiment provides a kind of lock, and its technical scheme is as follows:

[0039] Such as Figure 6 to Figure 8 As shown, a lock includes the above-mentioned screw key 100, a lock core 200, and a housing 300. The lock core 200 is a solid spiral column that matches the screw key 100, and the lock core 200 is installed in the housing 300. .

[0040] In the lock described in this embodiment, the screw key 100 cooperates with the solid spiral columnar lock core 200 to drive the lock core 200 to rotate in the housing 300 to realize locking and unlocking. The hole groove 1122 on the screw key 100 is equivalent to For the tooth flower, it is hidden on the inner surface of the spiral section 112, which effectively protects the tooth flower information. Paper, inkpad, plasticine and other tools cannot copy and copy the tooth flower information, avoiding the spiral key. 100 is illegally copied and copied, which greatly improves the safety of the lock, and the structure ...

Abstract

The invention discloses a spiral key which comprises a key head, a key handle and a connecting pin. The key head is connected with the key handle in a rotatable mode, the key head is of a hollow structure, and the key head comprises a spiral section and an installation section connected with the spiral section, wherein the spiral section is of a thread structure. A hole groove is formed in the inner surface of the spiral section. A limiting groove is formed in one end, away from the spiral section, of the installation section, and the connecting pin comprises an insertion section and a clamping section connected with the insertion section. A limiting part is arranged on the outer surface, close to the clamping section, of the insertion section, the connecting pin is installed in the key head, the limiting part is clamped in the limiting groove and can move up and down along the limiting groove, and the key handle comprises an installation hole and a clamping hole communicated with the installation hole. A first elastic part is arranged in the clamping hole, and the installation section is arranged in the installation hole. The key head has a free state and a clamping state relative to the key handle. The invention further provides a lock.

Description

technical field [0001] The invention relates to lock technology, in particular to a lock and its screw key. Background technique [0002] Locks are commonly used tools for protecting property in people's lives. With the continuous advancement of science and technology, the types of locks are increasing, and people's safety requirements for locks are also increasing. In traditional locks, the lock core usually adopts the structure of a linear insertion groove. The lock of this structure is easy to be opened by illegal elements with iron wire or master key, and the safety factor is low. In order to improve the safety factor, a spiral lock has been developed. The lock core is a spiral insertion groove. When unlocking the lock, the key is manually driven into the lock cylinder along the spiral insertion groove. The insertion groove spirally withdraws from the lock cylinder, which is very inconvenient to operate. Contents of the invention [0003] Based on this, the object of...
