Abstract
The utility model relates to a lock device, and particularly relates to a lock device used on a rotatable crane console. The novel lock device comprises a fixed base, a brake pad, a connecting shaft, a brake pad fixing seat, a rotating shaft, a handle, and paired conversion gears, wherein the connecting shaft is movably inserted into a through hole on the fixed base; the handle is fixed at the bottom end of the connecting shaft; the brake pad and the brake pad fixing seat are connected into a whole body through the rotating shaft; the paired conversion gears are respectively arranged at the upper end of the connecting shaft and the tip of the rotating shaft; and the paired conversion gears are mutually meshed. The novel lock device is simple in structure, and convenient to operate; the handle is rotated to drive the connecting shaft to rotate; the rotating shaft is driven to rotate via the paired conversion gears and then transmitted to the brake pad; locking and loosening are achieved by ascending and descending of the brake pad; and the novel lock device can accurately position, and is rapid to lock, and safe and reliable to run at the same time.
Description
Technical field
The utility model relates to a kind of latching device, the latching device that particularly uses on a kind of rotatable crane control desk.
Background technology
In working at the scene, the operator is sitting in when operating in seat on the whirley control desk, tends to rotate control desk, makes it reach the angle of a suitable job, then locks by latching device.Locking device structure in the past is complicated, there is unreasonable part in design, and cost of manufacture is high, and can not well locate, and usually causes very large trouble to operating personal.
The utility model content
The utility model has overcome shortcoming of the prior art, and a kind of new type of locking device is provided, and is simple in structure, accurate positioning, quick locking.
In order to solve the technical matters of above-mentioned existence, the utility model is achieved through the following technical solutions: new type of locking device, comprise that permanent seat, brake facing, adapter shaft, brake facing permanent seat, S. A., handgrip, pairing conversion gear form, in through hole on permanent seat, activity is fitted with adapter shaft, handgrip is fixed on the adapter shaft bottom, brake facing and brake facing permanent seat connect into as a whole by S. A., the pairing conversion gear is contained in respectively on the termination of the upper end of adapter shaft and S. A., and the pairing conversion gear is intermeshing.
Described pairing conversion gear adopts intermeshing finishing bevel gear cuter.
The utility model is simple in structure, and is easy to operate, rotates handgrip and drives the adapter shaft rotation, drive the S. A. rotation through the pairing conversion gear, then be delivered on brake facing, realize with descending that by hoisting of brake facing locking is with loosening, can accurately locate, quick locking, safe and reliable to operation simultaneously.

The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail:
New type of locking device as shown in Fig. 1-4, comprise that permanent seat 1, brake facing 2, adapter shaft 3, brake facing permanent seat 4, S. A. 5, handgrip 6, pairing conversion gear 7 form, in through hole on permanent seat, activity is fitted with adapter shaft, handgrip 6 is fixed on adapter shaft 3 bottoms, connect into brake facing 2 and brake facing permanent seat 4 use S. A.s 5 as a whole, pairing conversion gear 7 is contained in respectively on the termination of adapter shaft 3 upper ends and S. A. 5, pairing conversion gear 7 is intermeshing, and pairing conversion gear 7 adopts intermeshing finishing bevel gear cuter.
During assembling, first permanent seat 1 is fixed on the disk of below, handgrip 6 is fixed on adapter shaft 3, adapter shaft 3 passes permanent seat 1 simultaneously, then, brake facing 2 is connected with brake facing permanent seat 4 use S. A.s 5, become as a whole, at last, pairing conversion gear 7 is contained in respectively the two ends of adapter shaft 3 and S. A. 5, whole mechanism is linked together.
When operating personal will be adjusted the control desk angle, rotary handle 6, thus drive adapter shaft 3, be delivered on S. A. 5 by pairing conversion gear 7, finally make brake facing 2 break away from and the contacting of disk lower end, reach the purpose of rotating adjusting angle; When operating personal is adjusted angle, when needing fixedly control desk, opposite spin handgrip 6, thus drive adapter shaft 3 counter-rotatings, be delivered on S. A. 5 by pairing conversion gear 7, finally make end in contact under brake facing 2 and disk, reach the fixedly purpose of control desk.
Claims (2)
