Embodiment Construction

[0038] In the present invention, the separator and the turbine disperser are respectively equipped with an upper dismantling flow ring and a lower dismantling flow ring, and the materials are used to form an upper and lower circulation in the cylinder and a circulation around the cylinder, and the effect of the two circulations makes the material with a large diameter Quickly enter the circular grinding to improve the grinding efficiency; at the same time, the materials formed in the middle of the cylinder are distributed with larger and larger diameters from the inside to the outside, the smaller diameters are distributed around the separator, and the larger diameters are far away from the separator, so that the smaller materials are easily separated Separated to avoid the formation of discharge blockage.

[0039] Such as figure 1 , figure 2 with image 3 As shown, the present invention provides an embodiment of a mechanical combination lock.

[0040] This mechanical comb...

Abstract

Disclosed is a mechanical password lock, comprising a lock body and a key (1). The lock body comprises a lock housing (24) and a lock cover (25). A latching tongue (13) and a lock barrel connected by means of a transmission link (11) are arranged in the lock housing (24), and an elastic component (12) enabling the transmission link to be in close contact with the lock barrel is arranged on the transmission link (11). The lock barrel comprises a start wheel (6) with a start opening (62) and at least two groups of password assemblies (3). A spacer (5) with a stop opening (53) is arranged between two adjacent password assemblies (3), and stop bulges (52) mated with lock housing stop grooves (24, 26) are arranged on the spacer (5). Each password assembly (3) comprises an adjustment plate (31) and a gear plate (32). The centre and the edge of the adjustment plate (31) are respectively provided with a fixing hole (317) and a stop opening (312), a fixing tooth (316) mated with the gear plate (32) is arranged in the fixing hole (317), and a stop part (323) is arranged in a centre hole (322) of the gear plate (32). The key (1) is provided with guide grooves (18) mated with stop parts (323, 23, 63), and bayonets (19) mated with the password assemblies (3) are arranged in the guide grooves (18). The mechanical password lock can be unlocked by turning the key by only one hand.

Description

technical field [0001] The invention relates to the field of locks, in particular to a mechanical combination lock for safes or safes. Background technique [0002] Since the combination lock has a good effect of preventing non-destructive illegal opening, it is usually used in important areas or equipment, such as safes and safes, for the sake of confidentiality or security. [0003] Existing mechanical combination lock adopts starter wheel to drive the gear disc to rotate, and when connecting rod cooperates with adjusting disc, when rotating the starter wheel again, the dead bolt is driven by connecting rod to expand and contract. When using, the user needs to precisely rotate the turntable to rotate at a specific position, which is inconvenient for the user to operate and increases the difficulty of opening. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a mechanical combination lock, which can combine the ...
