Description

The lock body of key-type mechanical puzzle lock

Technical field

The utility model relates to a kind of coded lock, belongs to a kind of lock body of key-type mechanical puzzle lock.

Background technology

The key-type mechanical puzzle lock good confidentiality, stable performance, appearance looks elegant, do not dismantle lockset and just can change password, easy to use, but owing to the lock body structure reason of this lock, need during installation this lock is seated in the hole of opening on the door leaf, so not only destroy the overall structure of door leaf, and made installation inconvenient.

Summary of the invention

The purpose of this utility model provides a kind of lock body that makes key-type mechanical puzzle lock easy for installation.

The purpose of this utility model is to realize like this, it is the escape post of adorning by in the hole body on the lock body, spring, channel post, adorn the detachable cover clamp that is fixedly connected in the lock body, the framework sliding panel that is slidingly matched between lock body and cover clamp, the key sheet of adorning on the cover clamp and a reset key, the key flat spring that contacts with the key sheet, involution core and involution shell fragment are formed, described escape post top is special-shaped cylinder, its underpart is the cylinder that do not wait of diameter up and down, groove is established in the bottom surface of cylindrical lower prop, the diameter of cylindrical lower prop is less than the diameter of the hole bottom outlet of the hole body of lock body, and the diameter of cylindrical upward cylinder is greater than the diameter of the hole bottom outlet of the hole body of lock body; The hole is established in described channel post upper end, and its lower end is provided with the irregularly-shaped hole identical with the hetermorphiscal column shape of escape post, and the cylinder of channel post is provided with notch groove under groove and passage on the opposite passage.

The utility model is not dismantled the purpose that lockset just can change password because other parts of this structure of escape post and channel post and key-type mechanical puzzle lock cooperate to reach, and the bottom surface of escape post places in the hole bottom outlet of hole body of lock body, there is not outstanding position, need on door leaf, not punch during installation, therefore do not destroy the overall structure of door leaf, appearance looks elegant, easy for installation.The utility model can cooperate with existing key-type mechanical puzzle lock.

The specific embodiment

With reference to Fig. 1, present embodiment is between detachable lock body that is fixedly connected 9 and lock housing lid 18 a shaped as frame sliding panel 11 to be arranged, and shaped as frame sliding panel 11 is to be slidingly matched at lock body 9 and 10 of cover clamps.Lock body 9 has two row to hold the hole body 12 of escape post 1, and there is the hole bottom outlet less than hole body diameter the position, bottom, hole of hole body 12, and hole bottom outlet inwall is jagged, and escape post 1 and channel post 2 are housed in the hole body 12.With reference to Fig. 2, Fig. 3, Fig. 4, described escape post 1 top is special-shaped cylinder 3, the cross section of abnormity cylinder 3 can be semicircle or other geometry, its escape post 1 bottom is the cylinder that do not wait of diameter up and down, groove is established in the bottom surface of cylindrical lower prop 7, cylindrical lower prop 7 outer walls have projection, and the diameter of cylindrical lower prop 7 is less than the diameter of the hole bottom outlet of the hole body 12 of lock body 9, and the diameter of cylindrical upward cylinder 6 is greater than the diameter of the hole bottom outlet of the hole body 12 of lock body 9.With reference to Fig. 5, Fig. 6, Fig. 7, hole 14 is established in described channel post 2 upper ends, its lower end is provided with the irregularly-shaped hole 15 identical with special-shaped cylinder 3 shapes of escape post 1, irregularly-shaped hole 15 can be the hole of semicircle orifice or other geometry, and the cylinder of channel post 2 is provided with notch groove 5 under groove 4 and passage on the opposite passage.The lower prop 7 of escape post 1 places the hole bottom outlet of hole body 12, in the breach of the hole bottom outlet of the projection embedding hole body 12 of lower prop 7, the last cylinder 6 of its escape post 1 places hole body 12, and shock mount 8 inserts in the irregularly-shaped hole 15 of channel post 2 on the special-shaped cylinder 3 of escape post 1.Be the configuration detachable cover clamp that is fixedly connected 10 in channel post 2 upper ends in the lock body 9, each hole body 12 of corresponding lock body 9 has holding tank on the cover clamp 10, and key sheet 13 and a reseting plate are arranged in holding tank; Insert in the hole 14 of channel post 2 upper ends key sheet 13 lower ends, key flat spring 20 1 end in contact in the upper end of key sheet 13 and the key sheet lid 19, side contacts in the key sheet lid 19 in key flat spring 20 other ends and lock housing 18 holes, key sheet 13 1 sides have the barb that stretches out, when key sheet lid 19 is pressed, be in the next behind the reseting shrapnel 17 of reset coil 16 sides that the barb compression of key sheet 13 can be slided in lock body 9, key sheet barb upper surface contacts with the gib head following table of reseting shrapnel, has fixed the relative position of channel post 2 with shaped as frame sliding panel 11.Not dismantling coded lock only rotates the escape post and just can finish the operating principle of new password setting and be: available screwdriver places the groove of escape column bottom, rotating the escape post makes under the passage of channel post the groove notch outside, as right hand side keys sheet among Fig. 1, inside double wedge on the shaped as frame sliding panel can be the opening state of non-cryptographic key position by groove back and forth movement under the passage of channel post at this moment; Make on the passage of channel post the groove notch inside if rotate the escape post, as left side keys sheet among Fig. 1, this moment, this key position was the cryptographic key position, and channel post is in groove and the not concordant position of shaped as frame sliding panel on the passage, the shaped as frame sliding panel can not pass through channel post, and this state is the non-opening state in cryptographic key position.As long as press the key sheet lid of the cryptographic key position after changing, the key flat spring pushes down the key sheet and the downward pressure channel post of channel post spring is hooked by the involution shell fragment up to the barb of key sheet, groove is concordant with the shaped as frame sliding panel on the passage of channel post, the shaped as frame sliding panel can be in the cryptographic key opening state by groove on the passage of channel post.
