Detailed Description
The utility model will be further described with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and the detailed description. It should be understood that the detailed description and specific examples, while indicating the utility model, are intended for purposes of illustration only and are not intended to limit the scope of the utility model.
Referring to fig. 1-5, a novel interrogation chair comprises a chair body 1, wherein a bedplate 2 is hinged at the front end of the chair body 1, a bedplate locking mechanism 3 is arranged between the bedplate 2 and the chair body 1, and a shackle locking mechanism 4 is arranged below the chair body 1; the bedplate locking mechanism 3 comprises a shell 31, a triangular rotating tongue lock 32 is arranged in the shell 31, a locking hook 33 is arranged on a bolt of the triangular rotating tongue lock 32, the lower end of the locking hook 33 is connected with one end of a tension spring 34, the other end of the tension spring 34 is fixed in the shell, a locking buckle 35 is arranged on the side surface of the bedplate 2, and the locking buckle 35 and the locking hook 33 are matched with each other for use; the shackle locking mechanism 4 comprises a bottom plate 41, a pedal support 42 is arranged at one end of the bottom plate 41, a sleeve 43 is arranged at the other end of the bottom plate 41, a pedal 44 is hinged on the pedal support 41, a first connecting rod 45 is arranged below the pedal 44, a second connecting rod 46 is hinged on the first connecting rod 45, a lock pin 47 is hinged on the second connecting rod 46, the lock pin 47 penetrates through the sleeve 43, a pressure spring 48 is sleeved at the lock pin position in the sleeve 43, and the pressure spring 48 is limited in the sleeve 43. The method comprises the following specific steps:
platen locking mechanism 3: the locking of the bedplate 2 and the chair body 1 is completed by the engagement of the locking hook 33 and the locking buckle 35 on the bedplate 2, the engagement part of the locking hook 33 and the locking buckle 35 is sealed in a shell 31 arranged in the mechanism after locking and can not be opened by an inquirer, and after locking, the triangle rotating tongue lock 32 can be opened by a manager by using a special key, so that the whole bedplate locking mechanism 3 is opened;
