Embodiment 1

[0045] Such as figure 1 , figure 2 and image 3 As shown, the combination lock includes a lock body 1 and a combination lock box 2 that can control unlocking. The lock body 1 is a cylindrical structure with the upper end closing the lower end opening. The lock body 1 includes a petal body one 1a and a petal body two 1b that can be assembled into a cylindrical structure. The latter is fixed and controlled by the combination lock box 2 locking structure. The first petal body 1a and the second petal body 1b are in the shape of a circular arc plate, the first petal body 1a is hinged to one side of the second petal body 1b, and the locking structure is arranged between the first petal body 1a and the other side of the second petal body 1b. The inner side of the lower end of body one 1a and / or petal body two 1b has a shoulder 1c, and the shoulder 1c is arc-shaped. In this embodiment, the first petal body 1a and the second petal body 1b are semicircular in shape, and both the in...

Embodiment 2

[0054] The structure and principle of this embodiment are basically the same as that of Embodiment 1, the difference is that in this embodiment, the limit mechanism includes a card slot provided on the block 3c and a horizontally protruding set on the upper end of the actuator 8 When the locking wheel 7 rotates until the outer peripheral wall abuts against the protrusion 8a, the locking block can be inserted into the slot so that the dead bolt 3 is fixed. The lower end of the actuator 8 is hinged on the circular top plate 5a, and the elastic member is an unlocking torsion spring arranged at the hinge position between the actuator 8 and the circular top plate 5a.

Embodiment 3

[0056] The inner side of the upper end of petal body one 1a and the inner side of the upper end of petal body two 1b are fixedly connected with a semicircular baffle plate 13b, and the combination lock box 2 is fixed on the outer side of the first petal body 1a and part of the combination lock box 2 stretches out of the outer side of the first petal body 1a. The lock box 2 includes an outer shell 5 and a lock cylinder 6 arranged in the outer shell 5. The lock core 6 includes a rotatable locking wheel 7, and a movable actuator 8 is arranged between the locking wheel 7 and the bottom wall of the outer shell 5. , the actuator 8 is plate-shaped, and the locking structure includes a convex plate vertically connected to the bottom wall of the actuator 8 facing the shell 5 and a locking groove arranged on the outside of the petal body 2 1b. The surface of the actuator 8 facing the locking wheel 7 There is a protrusion 8a on it, and the outer peripheral wall of the locking wheel 7 can ...

Abstract

The invention provides a coded lock and a valve with the coded lock, and belongs to the technical field of valves. The problems that a valve with a locking function is low in reliability and poor in anti-opening performance are solved. The coded lock comprises a lock body and a coded lock box connected to the surface of the lock body, the lock body is of a barrel-shaped structure with the upper end closed and the lower end opened, the lock body comprises a first petal body and a second petal body which can be assembled into the barrel-shaped structure, a locking structure capable of fixing thefirst petal body and the second petal body and controlled by the coded lock box is arranged between the first petal body and the second petal body, and blocking shoulders are arranged on the inner sides / inner side of the lower ends / lower end of the first petal body and / or the second petal body. The coded lock has the advantages of high reliability, good anti-opening performance, good universalityand the like.

Description

technical field [0001] The invention belongs to the technical field of valves and relates to a combination lock and a valve with a combination lock. Background technique [0002] At present, valves with locking devices have been widely used in water supply pipelines, heating pipelines or gas pipelines, which can facilitate the management of community property or water supply companies. One of the structures of the valve with locking device is to equip the valve with a mechanical lock, such as a flanged ball valve with an opening and closing locking mechanism disclosed in Patent Application No. 201320250578.3, which makes the mechanical lock Can be hung on the valve to achieve locking. Its defect is that the mechanical lock needs to be opened with a key. When the number of lock control valves is large and the keys of each lock cannot be used in common, it is very unfavorable for centralized management. [0003] There is also a magnetic locking structure for valves with lock...
