Abstract
The invention aims to provide a self-locking draw-bar box. When the draw-bar box is closed for use, numbers of the cipher lock can be automatically disorganized so as to make the cipher lock come into play. To achieve the effect, the technical scheme is adopted as follows: the self-locking draw-bar box comprises a box body with rollers; the box body is provided with the cipher lock; a transmission gear is sleeved on a centre shaft between the two rollers; a gear case is arranged below the cipher lock of the box body; the transmission gear is connected into the gear case through a transmission shaft; and the gear case has three output ends which respectively fit with three swiveling wheels of the cipher lock. The invention has the following beneficial effects: when the draw-bar box is pulled, the rollers roll; and the transmission gear on the centre shaft is connected into the gear case through the transmission shaft, the swiveling wheels of the cipher lock are turned from inside in the output ends at random, and the effect of randomly disorganizing the cipher lock is realized.
Description
Technical field
The present invention relates to the case and bag field, especially a kind of self-locking draw-bar box.
Background technology
In life, in work, the tourism, people can choose a suitable draw-bar box usually for the ease of carrying a large amount of carry-on articles.Draw-bar box has brought facility for people's trip.
A lot of draw-bar boxes employing coded lock structures are encrypted and lock in the prior art, but a lot of users forget three numerals upsetting coded lock owing to seek conveniently behind the chest on closing, make coded lock perform practically no function.Even the people of a carefulness also might forget the numeral of upsetting this coded lock.To this, we need find a kind of simple structure, can upset this three numerals automatically in the process of using, and make coded lock really play effect.
Summary of the invention
The object of the present invention is to provide a kind of self-locking draw-bar box, when shutting the draw-bar box use, can upset the numeral of coded lock automatically, make coded lock play a role.
In order to reach described effect, the present invention adopts following technical scheme: a kind of self-locking draw-bar box, comprise the casing that has roller, described casing is provided with coded lock, be arranged with travelling gear on the axis between described two rollers, casing coded lock below is provided with gear-box, and described travelling gear inserts gear-box by power transmission shaft, described gear-box has three outputs, respectively three swiveling wheels of passwords lock.
Preferably, comprise a worm screw in the described gear-box, with three relay gears that are crisscross arranged, the diverse location of the corresponding worm screw of described relay gear, also be provided with an eccentric wheel on the described worm screw, power transmission shaft is connected on the eccentric wheel, and three relay gears connect three handsetting gears respectively, and the tooth of described handsetting gear contacts with the swiveling wheel surface.This structure is that the kinetic energy that comparatively simply roller is rotated changes into stirring the coded lock swiveling wheel.Like this as long as roller one rotates, just can stir the swiveling wheel of coded lock at random at the handsetting gear of coded lock inboard, play the effect that upsets the coded lock numeral at random.
Preferably, the outside of all teeth is provided with valve rubber on the described handsetting gear.Such structure is guaranteed the friction between the swiveling wheel of handsetting gear and coded lock, and minimizing is skidded.
Preferably, there is the outside of several teeth to be provided with valve rubber on the described handsetting gear.Make the position of several teeth skid easily like this, make the swiveling wheel of coded lock rotate more at random.
Preferably, be provided with disengaging gear between described travelling gear and the power transmission shaft.This disengaging gear can be a simple arrangement of clutch, makes to throw off between travelling gear and the power transmission shaft to connect.Can stop use of the present invention like this.
The present invention has following beneficial effect: when draw-bar box in when pulling, roller rolls.Travelling gear on the axis is connected in the gear-box by power transmission shaft, is stirred the swiveling wheel of coded lock at random from output port by the inboard, and realization upsets the effect of the position of coded lock at random.
Description of drawings
Fig. 1 is the overall structure schematic diagram of a kind of self-locking draw-bar box of the present invention.
Fig. 2 is the gear-box inner structure schematic diagram of a kind of self-locking draw-bar box of the present invention.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of self-locking draw-bar box, comprise the casing 1 that has roller 2, described casing 1 is provided with coded lock, be arranged with travelling gear 3 on the axis between described two rollers 2, the coded lock below of casing 1 is provided with gear-box 4, and described travelling gear 3 inserts gear-box 4 by power transmission shaft 5, described gear-box 4 has three outputs, respectively three swiveling wheels 6 of passwords lock.Comprise a worm screw 41 in the described gear-box 4, with three relay gears that are crisscross arranged 42, the diverse location of described relay gear 42 corresponding worm screws 41, also be provided with an eccentric wheel 43 on the described worm screw 41, power transmission shaft 5 is connected on the eccentric wheel 43, three relay gears 42 connect three handsetting gears 44 respectively, and the tooth of described handsetting gear 44 contacts with swiveling wheel 6 surfaces.The outside of all teeth is provided with valve rubber on the described handsetting gear 44.There is the outside of several teeth to be provided with valve rubber on the described handsetting gear 44.Be provided with disengaging gear 7 between described travelling gear 3 and the power transmission shaft 5.
Principle of the present invention is very simple, is exactly when the roller 2 of rolling draw-bar box, by the worm screw 41 in the power transmission shaft 5 driven gear casees 4.Power transmission shaft 5 is connected on the eccentric wheel 43, make worm screw 41 successively with three relay gears that are crisscross arranged 42 in one link to each other.The inertia of worm screw 41 when rotating drives relay gear 42 and rotates in very short distance.Because swiveling wheel 6 is own just very little, therefore rotates a little and just can change a password position.Relay gear 42 drives the swiveling wheel 6 that corresponding handsetting gear 44 is stirred coded lock, reaches the effect of upsetting the coded lock position.Even forget before using like this and upset password, also can remedy by such means.
The outside of all teeth is provided with valve rubber on the described handsetting gear 44.Increase the friction between handsetting gear 44 and the swiveling wheel 6.
In order further to improve randomness, there is the outside of several teeth to be provided with valve rubber on the described handsetting gear 44.Might occur skidding like this when the tooth that valve rubber is not set rotates, so sometimes can produce between handsetting gear 44 and the swiveling wheel 6 and skid, swiveling wheel 6 just can not change always.
Because the technical solution adopted in the present invention is comparatively severe to coded lock swiveling wheel surface abrasion, if therefore do not wish to adopt when of the present invention, can make to throw off between travelling gear 3 and the power transmission shaft 5 by disengaging gear 7 to connect.The present invention is with regard to used the same with common draw-bar box like this.
The applicant is noted that the method reality of the numeral of upsetting coded lock of the present invention still has certain rule after using repeatedly.But there is not to use for a long time the people of this draw-bar box still to be difficult to sum up this formula.Nonetheless, the numeral of upsetting coded lock before using the present invention earlier can play better secret effect.
