Detailed Description

The technical solution of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

Example one

As shown in fig. 1 to 3, the novel lock cylinder provided by the embodiment of the invention comprises a shell 1, a front lock shell 2, a rear lock shell 3, front pins 21, rear pins 31, a spring 32, a connecting shaft 4 and a lock cylinder plectrum 5.

The front lock shell 2 and the rear lock shell 3 are cylindrical, the axes of the front lock shell 2 and the rear lock shell 3 are hollow, and the rear end face of the front lock shell 2 is attached to the front end face of the rear lock shell 3; the front end of the connecting shaft 4 sequentially penetrates through the axes of the rear lock shell 3 and the front lock shell 2, the front end of the connecting shaft 4 is provided with a rotating operation structure for rotating the connecting shaft 4, and the rear end of the connecting shaft 4 is fixedly connected with a lock cylinder shifting piece 5. The connecting shaft 4 is rotated by the rotating operation structure, so that the lock core shifting piece 5 can be controlled to be unlocked.

Further, the outer shell 1 is sleeved outside the front lock shell 2 and the rear lock shell 3 and used for axially fixing the front lock shell 2 and the rear lock shell 3. One of the front lock shell 2 and the rear lock shell 3 is fixedly connected with the connecting shaft 4, and the other is fixedly connected with the shell 1; this makes it possible to rotate the connecting shaft 4 and thus to unlock via the cylinder tumblers 5 only if the front 2 and rear 3 lock cases can be rotated relative to each other. In this embodiment, the front lock case 2 is fixedly connected with the connecting shaft 4, and the rear lock case 3 is fixedly connected with the housing 1.

Furthermore, 6 rear lock holes 30 are formed in the rear lock shell 3, and the 6 rear lock holes 30 are uniformly distributed around the axis of the rear lock shell 3. The rear lock hole 30 is a blind hole extending along the axial direction, and an opening of the rear lock hole 30 is positioned on the front end surface of the rear lock shell 3; a spring 32 and a rear pin 31 are arranged in each rear lock hole 30, and two ends of the spring 32 respectively abut against the bottom surface of the rear lock hole 30 and the rear end of the rear pin 31, so that the front end of the rear pin 31 can be elastically and telescopically arranged at the opening of the rear lock hole 30.

The front lock shell 2 is provided with 6 front lock holes 20, and the 6 front lock holes 20 are uniformly distributed by taking the axis of the front lock shell 2 as the center. The number and the positions of the front lock holes 20 correspond to those of the rear lock holes 30 one by one; the front lock holes 20 are through holes which are through along the axial direction, and a front marble 21 is arranged in each front lock hole 20; the front marble 21 is axially movably arranged in the front lock hole 20 through an axial displacement adjusting structure; the rear ends of the front pins 21 abut against the front ends of the rear pins 31, and the length of each front pin 21 is different, so that the contact surfaces of the front pins 21 and the rear pins 32 in each group are located on different planes in the initial state.

Specifically, in the initial state, the contact surface between some of the front pins 21 and the rear pins 31 is located in the front lock hole 20, the contact surface between some of the front pins 21 and the rear pins 31 is located in the rear lock hole 30, and the contact surface between some of the front pins 21 and the rear pins 31 may be located at the junction between the front lock hole 20 and the rear lock hole 30. At this time, the front pin 21 and the rear pin 31 are blocked at the joint of the front lock case 2 and the rear lock case 3, and the front lock case 2 and the rear lock case 3 cannot rotate relatively, so that the connecting shaft 4 cannot rotate and the unlocking action cannot be performed through the lock cylinder shifting piece 5. Only when the axial position of the front pin 21 is adjusted through the axial displacement adjusting structure, and the contact surfaces of all the front pins 21 and the rear pins 31 are located at the joint of the front lock hole 2 and the rear lock hole 3, the front lock shell 2 and the rear lock shell 3 can rotate relatively, so that the connecting shaft 4 can rotate, and the unlocking action is performed through the lock cylinder shifting piece 5.

When all the contact surfaces of the front pins 21 and the rear pins 31 are located at the joint of the front lock hole 2 and the rear lock hole 3, the axial movement distance of each front pin 21 relative to the initial state is the information required for unlocking. By designing the axial displacement adjusting structure, the axial moving distance of the front pin 21 can be quantized and controlled, so that the unlocking operation is convenient.

In the present embodiment, the axial displacement adjusting structure includes an internal thread disposed on the inner wall of the front lock hole 20, an external thread disposed on the side surface of the front pin 21, and a rotation operation structure disposed at the front end of the front pin 21; the front pin 21 is screwed into the front lock hole 20 and is rotated by a rotation operation structure to move axially in the front lock hole 20. Further, the inner wall of the rear locking hole 30 is provided with an internal thread for being threadedly connected with the rear end of the front pin 21 when the rear end of the front pin 21 moves into the rear locking hole 30. According to the structure, the axial moving distance of the front marbles 21 can be controlled by controlling the rotating angle and the number of the circles of the front marbles 21, so that quantitative control is realized.

In addition to the threaded connection structure used in the present embodiment, various other axial displacement adjustment structures may be used in other embodiments of the present invention. Such as a toggle type retracting mechanism, a damped type retracting mechanism, and a push type automatic locking mechanism like a tail of an automatic ball pen, etc., which are not listed herein.

Accordingly, the rotary operation structure on the connecting shaft 4 and the front pin 21 may have various possible embodiments, such as various knobs, screw grooves, rotary handles, etc., and even a hole penetrating in the radial direction may be provided at the front end of the connecting shaft 4 and the front pin 21, and the rotary operation may be performed by inserting a bolt into the hole. The above structures are all included in the protection scope of the present invention. In this embodiment, the rotation operation structures on the connecting shaft 4 and the front pin 21 both adopt hexagonal screw grooves arranged on the front end surfaces of the connecting shaft 4 and the front pin 21; the complete unlocking operation can be carried out by using a common hexagonal wrench in daily life.

As an improvement, the novel lock cylinder provided by the embodiment further includes a limiting panel 10, and the limiting panel 10 is fixed on the front end surface of the front lock case 2. Specifically, spacing panel 10 is the sleeve form, and the side cover of spacing panel 10 is located preceding lock shell 2 side and is connected fixedly, and the terminal surface of spacing panel 10 is connected in the preceding terminal surface of preceding lock shell 2. The end face of the limiting panel 10 is provided with a plurality of limiting holes 11, the number and the positions of the limiting holes 11 correspond to the front lock holes 20 one by one, and the diameters of the limiting holes 11 are smaller than the diameters of the front lock holes 20.

The limit panel 11 is used to assist in marking the initial position of each front pin 21. Because the diameter of the limiting hole 11 is smaller than that of the front lock hole 20, when the front marble 21 moves outwards to the front end of the front lock hole 20, the front marble is blocked by the limiting panel 10 and cannot move outwards any more, so that the initial position of the front marble 21 is limited.

Furthermore, the front end face of the front marble 21 is provided with inner indicating scale marks, and the limiting hole 11 of the limiting panel 10 is provided with corresponding outer indicating scale marks. The inner indication scale marks and the outer indication scale marks can indicate the rotation angle of the front marble 21 by taking a ring as a unit, and if the limiting effect of the limiting panel 10 is not enough to accurately mark the initial position, auxiliary positioning can be carried out by means of the inner indication scale marks and the outer indication scale marks. When the front marble 21 abuts against the limiting panel 10 and the inner indication scale line is opposite to the outer indication scale line, the front marble 21 can be determined to be located at the initial position.

The purpose of returning the front pin 21 to the initial position after completion of unlocking is to facilitate the next unlocking. Only in the initial position can the user have a clear reference to determine how many turns and angles each front pin 21 needs to be rotated to achieve the unlocked state.

Of course, a reverse derivation method may be adopted, in which the user freely disturbs the position of each front pin 21 in the unlocked state, and after the front pin 21 moves, the lock cylinder is locked again. As long as the user can remember the information of the disorder, the lock can be unlocked again by reverse operation later. In this case, the initial position does not need to be marked, and the setting can be personalized by the user.

The novel lock cylinder provided by the embodiment of the invention is used as follows:

when the lock is unlocked, each front pin 21 is rotated by a specific number of turns and a specific angle by using a hexagonal wrench according to the initial state information of the lock cylinder, so that all the contact surfaces of the front pins 21 and the rear pins 31 are positioned at the joint of the front lock hole 20 and the rear lock hole 30. Then, the connecting shaft 4 can be rotated by using a hexagonal wrench, and then the lock is unlocked through the lock cylinder shifting piece 5.

After the unlocking is completed, the connecting shaft 4 is rotated back to the initial position, so that the front locking holes 20 and the rear locking holes 30 are restored to the one-to-one aligned state. Then, each front pin 21 is rotated to the initial position by using a hexagonal wrench, so that locking is realized.

Example two

As shown in fig. 4 and 5, the present embodiment is further improved on the basis of the first embodiment. Specifically, the front pin 21 in the present embodiment is hollow at the axial center. Through this structure, an unlocking method is additionally added. The rear marble 31 can be pushed to move backwards by inserting a rod-shaped object into the axis of each front marble 21, and when the rear marble 31 retracts into the rear lock hole 30, the front lock shell 2 and the rear lock shell 3 can rotate relatively to realize unlocking, so that the diversity of unlocking modes is increased. Based on this principle, an object with a plurality of protruding rods can be prefabricated as a 'key', and the length of each rod is matched with the axial length of the front lock shell 2, so that when the rods are completely inserted from the axial center of the front pins 21, each rear pin 31 can be pushed into the rear lock hole 30, and therefore unlocking is achieved.

Other structural details of the present embodiment are consistent with those of the present embodiment, and are not repeated herein.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
