The utility model has the advantages of simple structure, convenient use and more practical operation.

Description

Padlock

The utility model relates to lock technology field.

At present, the common padlock that arrives, it is the design that is to do on the axis round loop bar, to provide lockset after unblanking, pulling up axis can justify the mode that turns to the U type mouth hanging of axis top section is left the lockset top, can break away from the mouth hanging that is hung again, though it provides good rotation digit wheel mode of operation, but its reversion mode (must align under the password situation) is must be by the most beneath hole A by his thing, the interior cover B of pushing tow digit wheel axle, cause digit wheel C thereby displacement after, the side gives the reversion purpose that produces the change password, so on reversion is implemented, but must can finish the reversion mode, transfer to original very convenient mode complicated by his object space.So it is not very desirable in the use.

The purpose of this utility model provides a kind of padlock simple in structure, easy for operation.

For achieving the above object, the utility model is taked following design scheme: a kind of padlock, mainly being equiped with several digit wheels, digit wheel axle, the interior cover of number, briquetting, locking bar, reversion push rod and upper cover plate by a padlock body interior is formed, it is characterized in that: the left and right both sides, latch hook below of this padlock main body respectively is provided with one first opening, second opening and second opening part below and also is provided with the 3rd opening, and its first opening, second opening part side also are provided with a projection; The number digit wheel is made up of cover, a pressing plate and a spring in the digit wheel axle collocation number, the digit wheel axle is made ring of numbers depression paragraph shape and number indentation, cover in it is ccontaining, and cover in the number is the embedding digit wheel inner circular tooth that is provided with a flange in periphery, and is shaped on a flange at the quill shaft inwall, to embed in ring depression paragraph shape or the indentation, briquetting is arranged in padlock main body first opening, and it is provided with a pivoted hole, is pivot joint to be placed on the other projection combination of first opening; Upper cover plate is the opening that is provided with from the teeth outwards with digit wheel equity quantity, and also be provided with an opening with padlock main body the 3rd opening opposite position, locking bar is arranged in padlock main body second opening, it is provided with a pivoted hole and and presses portion, is pivot joint after being placed on the other projection combination of second opening; The reversion push rod is positioned at padlock main body the 3rd opening part, and it is the L moulding, and minor face is a top flat under this, and then there is a pushed section on long limit.

The utility model is described in further detail below in conjunction with accompanying drawing.

At first, as shown in Figure 2, the architecture advances of a kind of padlock of the utility model mainly is equiped with several digit wheels 2, digit wheel axle 21, the interior cover 7 of number, briquetting 3, locking bar 4, reversion push rod 5 and upper cover plate 6 by a padlock main body 1 inside and is formed; It is a left side below the latch hook 15 of padlock main body 1, right both sides respectively is provided with first a suitably big or small opening 11, second opening 12 also is provided with the 3rd opening 13 in the below at second opening, 12 places, its first opening 11, side, second opening, 12 places also is provided with a projection 14, for number digit wheel 2, one elasticity spacer 24, digit wheel axle 21, cover 7 in the number, briquetting 3,

locking bar

4,5 of reversion push rods place first opening 11 respectively, second opening 12, the 3rd opening 13 places, and be subjected to projection 14 to form two be pivoted switching and vertical slip state, number digit wheel 2, by overlapping 7 in the digit wheel axle 21 collocation numbers, one pressing plate 22 and a spring 23 are formed, its pressing plate 22 is for when briquetting 3 is moved, the effect of bearing of the portion that presses 42 of compressing locking bar 4, replied utilization by its below spring 23, and digit wheel axle 21 is to make ring of numbers depression paragraph shape 211 and number indentation 212, make its ccontaining interior cover 7 be provided with the embedding digit wheel 2 inner circular tooth 2A of a flange 71 in periphery, give in embedding ring depression paragraph shape 211 or the indentation 212 and be shaped on an inward flange 73 at quill shaft 72 inwalls, when the top flat 51 of reversion push rod 5 promotes and makes that cover 7 moves in each forward, and cover 7 inward flanges 73 are broken away from by ring depression paragraph shape 211 and when entering indentation 212 in causing, cover 7 outer Monday of flange 71 in then digit wheel 2 inner circular tooth 2A break away from is reversion and operates to provide; Briquetting 3 is arranged in padlock main body 1 first opening 11, and it is provided with a pivoted hole 31, being placed on other projection 14 combinations of first opening 11, and is the switching effect that is pivoted; Locking bar 4 is arranged in padlock main body 1 second opening 12, it is provided with a pivoted hole 41 and and presses portion 42, after projection 14 combinations that are placed on second opening, 12 sides, to be under the switching state that is pivoted, the portion that presses 42 when the pressure of briquetting 3 during at pressing operation touched locking bar 4 is under the switching phenomenon, so that locking bar 4 is also opened thereupon being relative switching direction, reversion push rod 5 still is positioned at padlock main body 1 the 3rd opening 13 places in addition, it is to be the L moulding, should beneath minor face be a top flat 51, then there is a pushed section 52 on long limit, and upper cover plate 6, it is the opening 61 that is provided with from the teeth outwards with digit wheel 2 reciprocity quantity, and also be provided with an opening 62 with padlock main body 1 the 3rd opening 13 opposite positions, be convenient to operation for reversion push rod 5.

So, to count digit wheel 2, digit wheel axle 21, cover 7 in the number, briquetting 3, locking bar 4, reversion push rod 5 places first opening 11 of padlock main body 1 respectively, second opening 12, the 3rd opening 13 places, and be subjected to projection 14 and form two to be pivoted switching and a vertical slip state (promptly shown in Fig. 3-A) afterwards, after digit wheel 2 goes to setting code, because each interior cover 7 inward flanges 73 have aligned ring depression paragraph shape 211 on the digit wheel axle 21, indentation 212 is a linearity, then make briquetting 3 when pressing operation, pressure is touched the portion that presses 42 of locking bar 4, and press a pressing plate 22 and the spring 23 that portion 42 presses digit wheel axle 21 jointly, cause the indentation 212 that originally was arranged in cover 7 flanges 71 on the digit wheel axle 21 to descend to move to ring

depression paragraph shape

211,4 of locking bars are opened (promptly shown in Fig. 3-B) thereupon being relative switching direction.

At this moment, when desire is set Change Password, then 52 places, pushed section by hand under unlocking condition up push away reversion push rod 5, each the interior cover 7 that makes top flat 51 will be exposed to digit wheel axle 21 moves forward, and cover 7 inward flanges 73 are broken away from by ring depression paragraph shape 211 and when entering indentation 212 in causing, cause digit wheel 2 inner circular tooth 2A thus break away under cover 7 outer Monday of flange 71 displacement actions, can make digit wheel 2 do resetting of change number one by one (as Fig. 4-A, shown in Fig. 4-B) afterwards, unclamp pushed section 52 again and make the inward flange 73 of interior cover 7 be back to ring depression paragraph shape 211 again by indentation 212, and become new code number number, digit wheel 2 is arbitrarily dialled it then made the inward flange 73 of inner interior cover no longer align indentation 212, align new password and can unblank and reset the password change operation just now to have only.

The utility model has the advantages that: simple in structure, easy to use, the operation more practical.
