[0023] Reference Figures 1 to 5 As shown, the push-pull unlocking lock cylinder of this utility model includes a cover plate 1, a lock cylinder shell 2, a drive seat 3, a knob 4, a rotating seat 5, a pin 6, a limiting ring 7, a retaining ring 8, and a drive plate 9. The lock cylinder shell 2 is installed on the outer side of the cover plate 1. The drive seat 3 is slidably and telescopically installed inside the lock cylinder shell 2. A spring 10 is installed on the drive seat 3. The knob 4 is installed on one end of the drive seat 3. The rotating seat 5 is rotatably installed on the cover plate 1 and passes through the cover plate 1. The limiting ring 7 is fitted on one end of the rotating seat 5 and is located on the inner side of the cover plate 1. The retaining ring 8 is engaged with the same end of the rotating seat 5 and is used to limit the limiting ring 7. The drive plate 9 is inserted into the same end of the rotating seat 5 in the axial direction. The other end of the rotating seat 5 is rotatably installed inside the other end of the drive seat 3. The pin 6 passes through the rotating seat 5 in the radial direction.

[0024] Reference Figures 3 to 5 As shown, the spring 10 is sleeved on one end of the drive seat 3 and is located inside the lock cylinder shell 2. The drive seat 3 has a step 11 in the middle. One end of the spring 10 abuts against the step 11 of the drive seat 3, and the other end of the spring 10 abuts against the inner wall of the lock cylinder shell 2.

[0025] By adopting the above technical solution, when the spring 10 is sleeved on the drive seat 3, the two ends of the spring 10 abut against the drive seat 3 and the lock cylinder shell 2 respectively, and the spring 10 provides elastic force for the drive seat 3 to retract and reset in the lock cylinder shell 2.

[0026] Reference Figure 5 As shown, the other end of the drive seat 3 is provided with a first spiral groove 12 and a second spiral groove 13, and the two ends of the pin 6 are slidably connected to the first spiral groove 12 and the second spiral groove 13 respectively.

[0027] Reference Figure 5 As shown, one end of the rotating seat 5 is recessed inward along the axial direction with a drive groove 14, and the drive plate 9 is movably inserted into the drive groove 14.

[0028] Reference Figure 5 As shown, one end of the drive seat 3 is provided with a connecting part 15, and the connecting part 15 extends laterally and is integrally formed with a protrusion 16.

[0029] By adopting the above technical solution, the protrusion 16 provides linear guidance for the drive seat 3 to extend and retract within the lock cylinder shell 2.

[0030] Reference Figure 5 As shown, a mounting groove 17 is recessed on one side of the knob 4.

[0031] By adopting the above technical solution, the connecting part 15 of the drive seat 3 is inserted into the mounting groove 17 of the knob 4 for docking, and the knob 4 is fixedly connected to the drive seat 3 by screws.

[0032] Reference Figure 5 As shown, one end of the rotating seat 5 is provided with a slot 18 for mounting the retaining ring 8.

[0033] By adopting the above technical solution, the retaining ring 8 is installed in the retaining groove 18 of the rotating seat 5. The retaining ring 8 limits the limiting ring 7 and prevents the rotating seat 5 from being misaligned on the cover plate 1.

[0034] Reference Figures 1 to 5 As shown, when the push-pull lock cylinder is installed on an interior door lock (i.e., an interior door unlocking structure), the pin 6 passes radially through the rotating seat 5. The two ends of the pin 6 are respectively spirally connected to the first spiral groove 12 and the second spiral groove 13. A connecting part 15 is provided at one end of the drive seat 3. The connecting part 15 extends laterally and is integrally formed with a protrusion 16. The protrusion 16 provides linear guidance for the extension and retraction of the drive seat 3 within the lock cylinder housing 2. Pulling the knob 4 causes the drive seat 3 to extend axially within the lock cylinder housing 2. A limiting ring 7 is fitted onto one end of the rotating seat 5, and the limiting ring 7 is located inside the cover plate 1. The limiting ring 7 axially limits the rotating seat 5, so that when the drive seat 3 extends axially within the lock cylinder housing 2, the drive seat 3... The first spiral groove 12 and the second spiral groove 13 drive the pin 6 to rotate, the pin 6 drives the rotating seat 5 to rotate, the rotating seat 5 drives the drive plate 9 to rotate, and the drive plate 9 rotates, thereby driving the lock to automatically unlock. This allows the door to be unlocked from inside the house simply by pulling the knob 4 without having to rotate it. At the same time, it does not require fixing the rotated lock knob. It has the advantages of simple and convenient unlocking, saving time and effort, quick unlocking, and a good unlocking experience. Moreover, the lock cylinder structure is simple, which further reduces production costs. It effectively solves the problem of traditional mechanical locks that require the lock knob to be rotated to the correct position inside the door and fixed before unlocking, which leads to time-consuming and laborious unlocking, inconvenient use, and poor unlocking experience.

One end of the spring 10 abuts against the inner wall of the cylinder of the drive seat 3, and the other end of the spring 10 abuts against the other end of the rotating seat 5.

[0037] By adopting the above technical solution, when the spring 10 is installed inside the cylinder of the drive seat 3, one end of the spring 10 abuts against the inner wall of the drive seat 3, and the other end of the spring 10 abuts against the other end of the rotating seat 5. The spring 10 provides elastic force for the drive seat 3 to extend and reset in the lock cylinder shell 2.

[0038] Reference Figure 7 As shown, the other end of the drive seat 3 is provided with a first spiral groove 12 and a second spiral groove 13, and the two ends of the pin 6 are slidably connected to the first spiral groove 12 and the second spiral groove 13 respectively.

[0039] Reference Figure 6 and Figure 7 As shown, one end of the rotating seat 5 is recessed inward along the axial direction with a drive groove 14, and the drive plate 9 is movably inserted into the drive groove 14.

[0040] Reference Figure 7 As shown, one end of the drive seat 3 is provided with a connecting part 15, and the connecting part 15 extends laterally and is integrally formed with a protrusion 16.

[0041] Reference Figure 7 As shown, a mounting groove 17 is recessed on one side of the knob 4. A retaining groove for mounting the retaining ring 8 is provided on one end of the rotating base 5.

[0042] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, when the push-pull unlocking lock cylinder is installed on an outdoor door lock (i.e., an external door unlocking structure), since the spring 10 is installed inside the cylinder on the drive seat 3, one end of the spring 10 abuts against the inner wall of the drive seat 3, and the other end of the spring 10 abuts against the other end of the rotating seat 5.

One end of the drive seat 3 is provided with a connecting part 15, and the connecting part 15 is laterally extended and integrally formed with a protrusion 16. The protrusion 16 provides linear guidance for the extension and retraction of the drive seat 3 in the lock cylinder shell 2. Pushing the knob 4 will cause the drive seat 3 to retract inward in the lock cylinder shell 2 in the axial direction. The limiting ring 7 is fitted on one end of the rotating seat 5, and the limiting ring 7 is located inside the cover plate 1. 7. The rotating seat 5 is axially limited, so that when the drive seat 3 retracts inward in the lock cylinder shell 2 along the axial direction, the drive seat 3 drives the pin 6 to rotate through the first spiral groove 12 and the second spiral groove 13. The pin 6 drives the rotating seat 5 to rotate, and the rotating seat 5 drives the drive plate 9 to rotate. The rotation of the drive plate 9 then drives the lock to automatically unlock. This allows the door to be unlocked from the outside simply by pushing the knob 4 without having to rotate it. At the same time, it does not require fixing the rotated lock knob. It has the advantages of simple and convenient unlocking, time-saving and labor-saving unlocking, fast unlocking, and good unlocking experience. Moreover, the lock cylinder structure is simple, which further reduces production costs. It effectively solves the problem that traditional mechanical locks require the lock knob to be rotated to the correct position on the door and fixed before unlocking, which leads to time-consuming and labor-intensive unlocking, inconvenient use, and poor unlocking experience.
