Description

Technical Field

[0001] This utility model belongs to the field of laptop lock technology, and more specifically, it relates to a universal laptop lock. Background Technology

[0002] Laptop locks are security products that prevent laptops from being stolen through physical means. They generally consist of several parts: a locking cable, a lock (with a password or key), a T-shaped latch, and a key (for key locks). They achieve physical security by locking with a keyhole on the device.

[0003] Existing laptop locks typically have non-adjustable locking cylinders, with a fixed opening angle at the factory. This can lead to unstable connections due to wear variations in the lock holes when connecting to a laptop. Therefore, this paper researches and improves upon existing structures and shortcomings to provide a universal laptop lock with greater practical value. Utility Model Content

[0035] As attached Figure 1 To be continued Figure 8 As shown:

[0036] This utility model provides a universal laptop lock, including a lower housing 1, a lock cylinder housing 3, and a key 13. An upper housing 2 is internally connected to the lower housing 1. The upper housing 2 is composed of a first housing 201 and a second housing 202. A fixing block 8 is fixedly installed between the first housing 201 and the second housing 202. A threaded hole is provided at the center of the fixing block 8, and an adjusting shaft 9 is connected through the threaded hole. The bottom end of the adjusting shaft 9 has a tapered head that protrudes from the bottom side of the fixing block 8. An adjusting wheel 11 is connected to the top end of the adjusting shaft 9. The adjusting wheel 11 is rotatably installed between housing one 201 and housing two 202; a lock head 6 is installed between housing one 201 and housing two 202 near the bottom of the fixing block 8. The lock head 6 is composed of a first pawl 601 and a second pawl 602. The first pawl 601 and the second pawl 602 are cross-connected by a connecting shaft 603, and the two ends of the connecting shaft 603 are rotatably connected to the inner sides of housing one 201 and housing two 202 respectively; the tapered head of the adjusting shaft 9 is installed between the first pawl 601 and the second pawl 602 and fits against them.

[0037] The top outer sides of both the first clasp 601 and the second clasp 602 are provided with arc-shaped grooves, and a rubber ring 7 is fitted between the two sets of arc-shaped grooves to ensure that the tops of the first clasp 601 and the second clasp 602 can fit tightly with the conical head of the adjusting shaft 9, so that the first clasp 601 and the second clasp 602 can quickly retract after the adjusting shaft 9 is raised and adjusted.

[0038] The lock head 6 extends from the bottom end of the upper housing 2; the bottom end of the upper housing 2 extends from the bottom end of the lower housing 1 and is fastened to the lower housing 1 by a snap ring 14, so as to ensure the connection stability between the upper housing 2 and the lower housing 1.

[0039] The housing 202 has a mounting groove on one side, and one end of the lock cylinder housing 3 is fixedly installed in the mounting groove. A rotating ring 301 and a fixed ring 302 are installed inside the lock cylinder housing 3. A lock cylinder shaft 304 is inserted inside the rotating ring 301 and the fixed ring 302. The lock cylinder shaft 304 is a hollow shaft sealed at one end and has an oblong hole on one side. A locking pin 305 is installed inside the oblong hole. One end of the locking pin 305 is fixedly connected to the fixed ring 302. A spring 306 and a spring 307 are installed on both sides of the locking pin 305 inside the lock cylinder shaft 304. The other end of the spring 307 is connected to a brake block 303.

[0040] The brake block 303 is slidably installed inside the mounting groove and located on one side of the adjusting wheel 11. The side of the adjusting wheel 11 is provided with multiple sets of brake grooves 10 that can be connected to the brake block 303 at equal angles, so that the adjusting wheel 11 connected to it can be quickly tightened after the adjusting shaft 9 is adjusted, so as to ensure that the whole has high stability after locking.

[0041] The lock cylinder 304 has a locking groove on one side, and the fixing ring 302 has a mounting hole on its inner side. A locking block 309 for locking with the locking groove is installed inside the mounting hole. A spring 308 is installed between the locking block 309 and the mounting hole, so that after pressing the lock cylinder 304, the locking block 309 can quickly lock with the locking groove under the action of the spring 308. This ensures that the lock cylinder 304 can stably press the brake block 303, so that one end of the brake block 303 is firmly engaged in the brake groove 10, ensuring high stability of the adjusting wheel 11 after adjustment. Simultaneously, when the lock cylinder 304 is rotated, the locking groove can move away from the locking block 309, and under the action of springs 306 and 307, it can move outward a certain distance. At this time, the locking block 309 will be compressed and remain on the lock cylinder 304. The surface is designed to facilitate locking upon subsequent pressing. One side of the rotating ring 301 has multiple sets of through holes, and each set of through holes contains a fixing pin 3011. One end of each fixing pin 3011 is connected to a spring 3010. One side of the fixing ring 302 has multiple sets of connecting holes, and the other end of each spring 3010 is correspondingly connected to a connecting hole. Through the cooperation of the fixing pin 3011 and the spring 3010, after the rotating ring 301 drives the lock cylinder 304 to rotate, the rotating ring 301 can quickly reset the lock cylinder 304. After reset, the lock cylinder 304, under the action of springs 306 and 307, moves outward a distance, releasing the pressure on the brake block 303. At this time, the key 13 can be used to drive the adjusting wheel 11 for adjustment, thereby driving the lock head 6 to open or close.

[0042] The lock cylinder housing 3 has a connection hole at one end that matches the key 13, and a connection groove at one end that matches the key 13. One end of the lock cylinder shaft 304 extends out of the connection hole so that the user can press and lock it after adjustment, which has high operational convenience.

[0043] The mounting groove of the housing 202 has through holes on both the upper and lower sides. A connecting pin 12 is installed inside each of the through holes. One end of the connecting pin 12 passes through the lock cylinder housing 3 and is fixedly connected to the fixing ring 302.

[0044] One side of the housing 202 is connected to a connecting post 5, and one end of the connecting post 5 is fixedly connected to a steel wire rope 4.

[0045] The top of the adjusting shaft 9 is provided with a square shaft, and the bottom side of the adjusting wheel 11 is provided with a rectangular groove that is slidably connected to the square shaft; the top of the adjusting wheel 11 is provided with a connecting groove that is matched and connected to the key 13.

[0046] The working principle of this embodiment is as follows: By using the fixed block 8 in conjunction with the adjusting shaft 9, the adjusting wheel 11 at the top of the adjusting shaft 9 can be rotated to drive the adjusting shaft 9 to adjust up and down, thereby squeezing and adjusting the first pawl 601 and the second pawl 602 of the lock head 6. After the first pawl 601 and the second pawl 602 are inserted into the lock hole of the laptop, they will quickly open to achieve stable locking of the lock hole. This method has high applicability and flexible use.

[0047] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
