Description

TECHNICAL FIELD

[0001] The present application relates to a lock suitable for a one-key, in particular to a one-key idle blade lock cylinder assembly and its key. BACKGROUND

[0002] At present, the common one-key on the market is generally suitable for a pin tumbler lock cylinder. The one-key is simple in shape and easy to process, and is favored by users. The one-key is used to cooperate with each pin through the high and low tooth pit distributed on one side or both sides, so that each pin is located in the appropriate position, thereby enabling the lock cylinder to rotate and unlock. In order to make the key more convenient to insert into the lock cylinder, each tooth pit has a certain taper, resulting in a transition section between adjacent tooth pits, and a distance between adjacent tooth pits and pins, resulting in a small number of effective tooth pits and pins within a certain length, a limited number of tooth pit arrangement combinations, and a mutual opening phenomenon. The conventional pin tumbler lock cylinder cannot be idle, and is easily damaged by violent twisting. The one-key cannot be directly used in the idle blade lock cylinder. Therefore, the existing lock suitable for the one-key has the problems of easy mutual opening and easy damage by violent twisting. SUMMARY

[0003] The purpose of the present application is to provide a one-key idle blade lock cylinder assembly and its key. The present application not only reduces the mutual opening rate, but also has the advantage of not being easily damaged by violent twisting.

[0004] The technical solution of the present application is a one-key idle blade lock cylinder assembly, comprising a number sheet sleeve, a plurality of number sheets and spacers arranged at intervals in the number sheet sleeve; the number sheet sleeve is provided with a needle roller groove and a rotation stopping groove for fixing the spacers, and the needle roller groove is provided with a needle roller; each spacer is provided with a spacer groove at a position corresponding to the needle roller groove on the outer side; each number sheet is provided with a special-shaped through hole in the middle, and the special-shaped through hole is provided with a plurality of tooth grooves arranged in a stepped manner, all the tooth grooves are arranged in a ring shape around the center of the number sheet, and there is only one tooth groove for unlocking in all the tooth grooves; each number sheet is provided with a number sheet groove on the outer edge, and when the tooth groove for unlocking in each number sheet rotates and is located at the same position, all the number sheet grooves are aligned.

[0005] In the foregoing one-key idle blade lock cylinder assembly, the number sheet groove provided on the outer edge of the number sheet is aligned with any level tooth groove.

[0006] In the foregoing one-key idle blade lock cylinder assembly, the spacer is provided with a boss at a position corresponding to the rotation stopping groove on the outer side.

[0007] In the foregoing cylinder assembly of the dead bolt lock for the single key, the both ends of the number sheet sleeve are respectively provided with the key positioning hole and the sealing sheet, and the sealing sheet is provided with the key hole.

[0008] In the foregoing cylinder assembly of the dead bolt lock for the single key, the outer edge of the sealing sheet corresponding to the key hole is provided with the guide recess.

[0009] In the foregoing cylinder assembly of the dead bolt lock for the single key, the number sheet sleeve is provided with the bevel groove corresponding to the position of the outer side of the sealing sheet, and the bevel groove is provided with the elastic spring sheet.

[0010] In the foregoing cylinder assembly of the dead bolt lock for the single key, the outer edge of the spacer is provided with the friction tooth.

[0011] A key comprises a key head and a key handle connected with each other, and the key head is provided with multiple levels of teeth on the side corresponding to the position of each number sheet in the number sheet sleeve, and the side of each level of teeth is vertical; the teeth can be matched with the tooth groove for unlocking when the key head rotates, and the number sheet groove on the outer edge of the number sheet sleeve can be aligned with the needle groove.

[0012] In the foregoing key, the thickness of the two sides of the key head is different.

[0013] Compared with the prior art, the present application sets multiple interval arranged number sheets and spacer sheets in the number sheet sleeve, the spacer sheet is limited by the rotation stopping groove and can only rotate synchronously with the number sheet sleeve, while the number sheet can rotate in the number sheet sleeve; the middle part of the spacer sheet is provided with a through hole for the key to pass through and rotate, and the middle part of the number sheet is provided with a special-shaped through hole which can only pass through when the key is aligned; after a non-correct key is inserted into the lock core, only the number sheet can be driven to idle, effectively avoiding the lock core from being violently twisted and damaged; meanwhile, the special-shaped through hole is provided with multiple level arranged tooth flower grooves in a stepped manner, all the tooth flower grooves are distributed in a ring shape around the center of the number sheet, so that the number of the level of the tooth flower grooves is not affected by the axial length of the lock core, and there is no need for an inclined transition section between the adjacent tooth flowers on the key, so that more effective tooth flowers and number sheets can exist in a certain length of the lock core, greatly reducing the mutual opening rate. In addition, the spacer sheet is clamped with the rotation stopping groove through the outer convex plate to prevent the spacer sheet from rotating in the number sheet sleeve, so that the structure stability is relatively strong; the sealing sheet at one end of the number sheet sleeve can stably press the number sheet and the spacer sheet in the number sheet sleeve, ensuring the structural stability; the key positioning hole at the other end of the number sheet sleeve is used for cooperating with the tooth flower free position at the top end of the key to position the key; the key hole position of the sealing sheet is provided with a guide recess, which can guide the key, facilitating the key to align and insert into the key hole; the position corresponding to the outer side of the sealing sheet on the number sheet sleeve is provided with an inclined groove, which can more stably limit the elastic spring sheet, and the elastic spring sheet can stably press the number sheet and the spacer sheet in the number sheet sleeve, ensuring the structural stability; the outer edge of the spacer sheet is provided with friction teeth, which can further prevent the number sheet from rotating across, ensuring the structural stability; meanwhile, the present application also sets the key corresponding to the above lock core assembly, the key head is provided with multiple level tooth flowers which are not completely the same in height and are arranged side by side, which are used for cooperating with the tooth flower grooves on the number sheet, and the processing is relatively convenient; the side edges of the multiple tooth flowers on the key head are vertically arranged, the tooth flower spacing can be reduced to 2mm, so that more tooth flowers can exist in a certain length, reducing the mutual opening rate, and being more suitable for occasions where the lock core is relatively short and the number of tooth flowers is required. Therefore, the present application not only can reduce the mutual opening rate, but also has the advantages of not being easily damaged by violent twisting, relatively strong structural stability, convenient key insertion, convenient processing, being suitable for occasions where the lock core is relatively short and the number of tooth flowers is required, and smooth key rotation.
