Abstract

The utility model discloses a button mechanism which is characterized by comprising racks, external force button pieces, transmission small teeth which are arranged on sides of the lower portions of the racks, and ratchets which are arranged on the other sides of the lower portions of the racks. Each ratchet comprises a first ratchet and a second ratchet, wherein the first ratchet and the second ratchet are sequentially arranged from top to bottom. First stage steps and second stage steps are sequentially arranged on the upper portions of the racks from top to bottom. Positioning elastic clamping pieces are arranged on ratchet sides of the racks, rack restoration springs are arranged on the racks, button restoration springs are arranged on the external force button pieces, and under the pressed effect of the external force button pieces, the positioning elastic clamping pieces are in clamped connection with first ratchets and second ratchets which are arranged on the lower portions of the racks. When a coded lock is arranged, the button mechanism has the advantages of improving the amount of coded arranged information of a code lock, and being simple in structure, low in cost and convenient to use.

Description

Press button mechanism

Technical field

The utility model relates to the coded lock technology field, is the technology of press button mechanism specifically.

Background technology

Existing push-button puzzle lock, its each press button mechanism that is used for password generally can only be by once arranging when password is set, this password key mechanism is so that coded lock password configuration information is less, increase encrypted message, must increase the quantity of button and press button mechanism, cost increases like this, and volume strengthens, and is difficult to satisfy people's needs.

Summary of the invention

The purpose of this utility model provides a kind of coded lock of raising password configuration information amount that has, and simple in structure, cost is low, press button mechanism easy to use.

The utility model is achieved through the following technical solutions.

A kind of press button mechanism, it is characterized in that: described press button mechanism comprises tooth bar, the external force button piece, side in the tooth bar bottom is provided with the little tooth of transmission and is provided with ratchet at opposite side, described ratchet comprises the first ratchet and the second ratchet that is arranged in order from bottom to top, described tooth bar top is provided with first order step from bottom to top successively, second level step, in the rack ratchet side location elastic card is installed, at tooth bar the tooth bar back-moving spring is installed, on the described external force button piece button back-moving spring is installed, the location elastic card under the effect of external force button piece pressurized with the first ratchet or the second ratchet phase clamping of tooth bar bottom.

The middle part of described tooth bar bottom and between the little tooth of transmission and rack ratchet, be provided with the guiding slide opening, first order step, second level step are located at the top of rack ratchet side, the end face on the top of the little tooth of transmission is shaped to first order step surface, each rack ratchet is equipped with crown section, tooth plane and tooth inclined-plane, wherein the tooth plane is upper, the tooth inclined-plane is lower, and the tooth plane is perpendicular to the length direction of tooth bar.

Described location elastic card is provided with inclined plane part and is connected planar portions, and the location elastic card is by connecting planar portions and the first ratchet or the second ratchet phase clamping.

The utility model compared with prior art has the following advantages.

By technical scheme described in the utility model, described press button mechanism is can be by the press button mechanism of secondary, namely when the external force button piece resets fully with the tooth bar that is provided with the secondary tooth, the first order step of external force button piece and tooth bar is fitted, when pushing button certain distance, the ratchet on the tooth bar the right elastic card that is positioned blocks, and button is finished for the first time action; The external force button piece resets under the effect of button back-moving spring after the external force button piece unclamps, snapped-in position can be inserted the second level step of tooth bar automatically, when again pushing button, the external force button piece withstands on the second level step of tooth bar, together tooth bar is pressed, finished for the second time action until the elastic card that is positioned blocks button.As seen, when the utility model is installed on coded lock, have the coded lock of raising password configuration information amount, simple in structure, cost is low, and is easy to use.

The specific embodiment

Below in conjunction with accompanying drawing the utility model press button mechanism is described in further detail.

As Figure 1-3, the utility model press button mechanism, comprise external force button piece 2, tooth bar 4, button card 1 is installed on the external force button piece 2, side in tooth bar 4 bottoms is provided with the little tooth 41 of transmission and is provided with ratchet at opposite side, ratchet comprises the first ratchet 42 and the second ratchet 43 that is arranged in order from bottom to top, also be provided with successively first order step 44 from bottom to top on tooth bar 4 tops, second level step 45, in the rack ratchet side location elastic card 6 is installed, at tooth bar 4 tooth bar back-moving spring 5 is installed, at external force button piece 2 button back-moving spring 3 is installed, location elastic card 6 under the 2 pressurized effects of external force button piece with the first ratchet 42 or the 43 phase clampings of the second ratchet of tooth bar 4 bottoms.The little tooth 41 of transmission is meshed with a gear 7.Each component of press button mechanism support by lock body 8.

At the middle part of tooth bar 4 bottoms and between the little tooth of transmission and rack ratchet, be provided with the guiding slide opening 46, first order step 44, second level step 45 are located at the top of rack ratchet side, the end face on the top of the little tooth 41 of transmission is shaped to first order step surface 44, each rack ratchet is equipped with crown section, tooth plane and tooth inclined-plane, wherein the tooth plane is upper, the tooth inclined-plane is lower, and the tooth plane is perpendicular to the length direction of tooth bar.Location elastic card 6 is provided with inclined plane part 61 and is connected planar portions 62, and location elastic card 6 is by connecting planar portions 62 and the first ratchet 42 or the 43 phase clampings of the second ratchet.

Press button mechanism described in the utility model is a kind ofly can namely adopt secondary tooth bar and secondary position limiting structure by the press button mechanism of secondary, realizes arranging by secondary continuously the function of password.
