Abstract
The utility model relates to a main steering plate fixing mechanism of the safe case password lock and is especially a loose preventing mechanism for the safe case password lock main steering plate locknut including a transmission shaft, a transmission sleeve coordinated with the outside diameter of the lower end of the transmission shaft by screw thread, a main steering plate coordinated with the outside diameter of the lower end of the transmission sleeve and locked tightly with the shoulder of the transmission sleeve by using the bolt, a key positioned between the transmission sleeve and the transmission shaft and a locknut positioned at the end of the transmission shaft and a spring cushion, a brake plate is arranged between the locknut and the spring cushion, the inner hole of the spring cushion is in lunar shape or sulciform, and coordinates with the figure of the transmission shaft, the brake plate has two vanes wrapping at the lateral surface of the locknut. The utility model is simple in structure, reliable in loose stopping performance.
Description
The utility model relates to a kind of main direction turning piece fixed mechanism of safety cabinet coded lock, is a kind of loosening mechanism that prevents of safety cabinet coded lock master direction turning piece locking nut specifically.
As the patent No. is 96250191.3 described coded lock master direction turning piece fastening devicess, provides a kind of and has had password and change convenient, as to improve password replacing amount and size of key, characteristics such as simple in structure, safe and reliable fastening devices.Improve to some extent on the existing products in markets structure, promptly set up a locking nut in the drive sleeve lower end, or a locking nut and a spring shim have been set up, deviate from keyway to avoid key, but when reality is used, locking nut also can become flexible, and causes that key deviates from keyway, causes whole coding mechanism to lose efficacy.
The purpose of this utility model is to provide a kind of coded lock master direction turning piece locking nut stopping device of simple in structure, retaining dependable performance.
The purpose of this utility model is achieved like this, coded lock master direction turning piece locking nut stopping device comprises power transmission shaft, with the drive sleeve of power transmission shaft lower end external diameter with threaded engagement, cooperate with the drive sleeve external diameter and with the drive sleeve shoulder with the fastening main direction turning piece of screw, key between drive sleeve and power transmission shaft and be positioned at locking nut and the spring shim that power transmission shaft is not held, characteristics are to establish a check plate between locking nut and spring shim, the check plate endoporus is moon shape or flute profile, match with the power transmission shaft profile, avoid power transmission shaft and check plate to rotate mutually, check plate has two fins to be wrapped in the side of locking nut tightly, utilize the corner angle of locking nut, prevent that locking nut from rotating.
The utlity model has following advantage: only establish a check plate between locking nut and spring shim, do not increase other mechanisms, structure is very simple; The check plate fin is wrapped on the corner angle of locking nut side tightly, and check plate is connected with the power transmission shaft spline, makes the locking nut retaining reliable.
Below in conjunction with drawings and Examples the utility model is done step detailed description.
Fig. 1 is the front view of the utility model embodiment
Fig. 2 is that the check plate of the utility model embodiment launches enlarged drawing
As shown in Figure 1 and Figure 2, present embodiment is made up of power transmission shaft 1, drive sleeve 2, the main direction turning piece 3 with power transmission shaft 1 threaded engagement, the screw 4 that is connected main direction turning piece 3 and drive sleeve 2, locking nut 5, key 6, spring shim 7 and the check plate 8 etc. that are positioned at power transmission shaft 1 and drive sleeve 2 keyways.
In the present embodiment, the endoporus of the profile of power transmission shaft 1 and drive sleeve 2 is a moon shape, can certainly adopt form cooperations such as groove, its objective is the mutual rotation that prevents between power transmission shaft 1 and the drive sleeve 2.For the ease of assembling, check plate 8 materials should adopt copper comparatively suitable, after coded lock is packed safety cabinet into, with the side of check plate 8 usefulness special tool rivetings at locking nut 5.
Be connected with key 6 with screw thread between power transmission shaft 1 and the drive sleeve 2, the shoulder of drive sleeve 2 and main direction turning piece 3 usefulness screws 4 are fastening, spring shim 7 is close to the lower surface of drive sleeve 2, and locking nut 5 and spring shim 7 itself are exactly in order to prevent that drive sleeve 2 from becoming flexible and key 6 is deviate from keyway.The setting of check plate 8 has improved the reliability of locking device widely.
