Problems solved by technology

The disadvantage of this structure is that the lock head uses the L-shaped side column to separate and connect the inner lock core and the starting core to realize idling and unlocking. Due to the single-side column transmission, the L The short end of the L-shaped side post and the side post groove of the starting core are constantly worn, and the matching gap increases, causing the L-shaped side post to be stuck in the side post groove of the lock body and the lock head cannot be opened.

Embodiment Construction

[0020] Applied in the implementation process of the present invention is such as Figure 9 key shown.

[0021] Such as figure 1 , figure 2 As shown, in order to realize the dual-drive unlocking of the L-shaped side column 9 and the lock cylinder block 6 in the shrapnel type idling lock head of the dual-drive unlocking, the inner lock cylinder 2 is provided with a mounting groove for the lock cylinder block 6 and a plurality of channels. It is convenient to install the through groove of the shrapnel 5; two opposite shrapnels 5 are loaded into each shrapnel through groove; one side of the shrapnel 5 has a U-shaped groove matching the lock cylinder block 6; the lock cylinder block 6 is installed on In the inner lock core 2, one end of it properly exceeds the inner lock core 2, and the part beyond the inner lock core 2 is processed into a plane step that is convenient to cooperate with the starting core groove 12, and simultaneously the lock core block 6 is provided with at lea...

Abstract

The invention discloses an elastic sheet type idling lock head capable of being unlocked through double transmission. A rotation part of the lock head mainly comprises an inner lock cylinder and a starting core, wherein the inner lock cylinder and the starting core are connected with each other through an L-shaped side column and a lock cylinder clamping block, so that an aim of unlocking the lock head is fulfilled; therefore, the transmission reliability of the lock head is relatively high, and friction among transmission parts are effectively reduced, and the service life of the lock head is prolonged; and the lock head is usually in an idling state, so that a phenomenon that the lock head is violently unlocked is effectively avoided. The elastic sheet type idling lock head can be applied to various locksets.

Description

Technical field [0001] The invention relates to a shrapnel-type idling lock head for dual-drive unlocking. Background technique [0002] Chinese patent ZL200920265479.6 discloses a shrapnel-type idling lock cylinder, which consists of a lock body, an inner lock cylinder, a lock cylinder block, an L-shaped side column, a starting core, a shrapnel, a spring, a clutch assembly, a lock opening piece and Keys and other accessories. Its working principle is to align the U-shaped grooves on each column of shrapnel in a straight line through different tooth patterns on the key. The L-shaped side post breaks away from the side post groove and enters the inner lock cylinder, so that the L-shaped side post connects the inner lock cylinder and the starting core, realizing the normal unlocking function of the lock head; when the key is pulled out, the pulling force of the key and the shrapnel spring Under the combined force of the elastic forces, the U-shaped grooves on each column of ...
