Embodiment Construction

[0010] Such as figure 1 and figure 2 As shown, a locking mechanism of a valve manual device includes a reduction box 1, an input shaft, and a hand wheel 11. A coupling sleeve 2 is also installed on the input shaft, and the coupling sleeve 2 is fixed on the reduction box 1. The input shaft is divided into input The shaft I 3 and the input shaft II 10, the ends of the input shaft I 3 and the input shaft II 10 are combined through a tooth shape, the ends of the combination of the input shaft I 3 and the input shaft II 10 are punched, and the spring I is housed in the hole 5. A fixing plate 4 is also installed on the connecting sleeve 2, and a hole is punched on the fixing plate 4, and a ladder-shaped lock pin 7 is installed in the hole. A spring II 9 is installed between them, and the lock pin 7 passes through the coupling sleeve 2 and cooperates with the circumferential groove 6 on the input shaft II 10 .

Abstract

The invention provides a lock mechanism of a valve hand appliance. The lock mechanism comprises a reduction box, an input shaft, and a hand wheel, wherein the input shaft is provided with a connecting sleeve, and the connecting sleeve is fixed on the reduction box; the input shaft is divided into an input shaft I and an input shaft II, the ends of the input shaft I and the input shaft II are combined through a tooth form, and the combined end of the input shaft I and the input shaft II is provided with a hole; a spring I is arranged in the hole, the connecting sleeve is provided with a fixed plate, the fixed plate is provided with a hole, a stepped lockpin is arranged in the hole, and a locking hole is arranged on the lockpin; and a spring II is arranged between a step of the lockpin and the connecting sleeve, the lockpin passes through the connecting sleeve so as to match with a circumference groove on the input shaft II. The lock mechanism provided by the invention has beneficial effects of simple structure and reliable locking, and can effectively prevent misoperation of not operation personnel.

Description

technical field [0001] The invention relates to a manual device, in particular to a valve manual device with a locking mechanism. Background technique [0002] At present, the locking mechanism used in valve manual devices mostly adopts a support plate fixed on the box body of the manual device, a hole is punched on the support plate, and a chain is passed through the hole on the support plate and the hand wheel and then locked with a padlock. Since the handwheel generally has three evenly distributed wheels, the chain cannot completely lock the handwheel, and accidents often occur when non-operators misuse the handwheel. Contents of the invention [0003] In order to overcome the disadvantages that the locking mechanism of the existing valve manual device cannot completely lock the hand wheel, and non-operators often cause accidents due to misoperation of the hand wheel, the present invention provides a locking mechanism of the valve manual device. [0004] The technical...
