Description

Technical field

[0001] The invention relates to the technical field of lock cylinder housings, in particular a novel lock cylinder housing. State of the art

[0002] A chain lock is an anti-theft device in which a metal chain forms the core of the locking mechanism and is combined with a rigid lock cylinder housing. Due to its high shear resistance, good protective effect, and wide range of applications, it is one of the most common solutions that balance security and practicality.

[0003] Currently available wire rope locks are common portable anti-theft devices widely used in temporary theft protection scenarios for bicycles, e-scooters, and small outdoor equipment. These locks typically consist of braided rope and a lock cylinder assembly, with their central locking mechanism achieving locking through the mechanical engagement of pegs and keyholes. In the conventional design, after unlocking, the user must manually pull the peg out of the keyhole to separate the lock body from the chain. This additional manual step not only reduces unlocking efficiency but also causes considerable inconvenience in situations such as rain, when wearing gloves, or when operating the lock with one hand.For this reason, a novel lock cylinder housing is proposed to solve the problems mentioned above. Content of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a novel locking cylinder housing with a more stable ejection device in which the plug-in angle extends automatically after unlocking without requiring manual operation, thereby increasing unlocking efficiency.

[0005] To achieve the aforementioned purposes, this invention provides the following technical solution: A novel lock cylinder housing comprising a first housing, characterized in that a hollow tube is arranged inside the first housing, wherein a first mounting part is arranged inside the hollow tube, and a lock cylinder is movably arranged inside the first mounting part, a rotary disc is movably arranged on the outer surface of the first mounting part, wherein a first spring is fixedly attached to the top of the first mounting part, a second mounting part is fixedly arranged on the side of the first mounting part facing away from the first mounting part, wherein a plug-in part is attached to the top of the second mounting part, wherein a second spring is fixedly attached to the inner bottom wall of the plug-in part, and a small disc-shaped cover is fixedly attached to the top of the second spring.and wherein a cylindrical locking pin is arranged on each of the left and right side walls of the plug-in part; wherein a plug-in angle is provided on the top of the small disc-shaped cover.

[0006] Furthermore, the outer wall of the first housing is provided with a connection opening that is flush with the locking cylinder.

[0007] Furthermore, the rotary disc is locked onto the outside of the lock cylinder.

[0008] Furthermore, the second assembly part comprises a disc body, two T-shaped locking blocks and a concave block, wherein the disc body is fixedly attached to the top of the first assembly part, wherein two T-shaped locking blocks are fixedly installed on the top of the disc body, and wherein the concave block is fixedly attached to the bottom of the disc body, and the turntable is designed to fit the concave block.

[0009] Furthermore, the plug-in part is firmly attached inside the first housing, with two locking recesses provided on the outer wall of the plug-in part, and the two cylindrical locking pins are each provided on the two locking recesses, with the two cylindrical locking pins being arranged above the T-shaped locking blocks.

[0010] Furthermore, the outer wall of the plug-in angle is provided with a groove that can receive the cylindrical locking pin, wherein the plug-in angle is latched to the upper wall of the first housing, a chain fastening part is fixedly attached to the side of the plug-in angle facing away from the first housing, wherein a chain element is fixedly attached to the surface of the chain fastening part, and a chain fastening part is also fixedly arranged on the lower wall of the first housing, and wherein the chain element is fixedly attached between the two chain fastening parts.

[0011] Furthermore, a second housing is permanently attached to both the top and bottom of the first housing.

[0012] Compared to the prior art, this invention has the following advantageous effects: With this innovative lock cylinder housing, the user turns the key to unlock the lock, causing the rotating disc to turn synchronously. Because the rotating disc is designed to fit the concave block of the second mounting part, it causes the second mounting part to move downwards and compresses the first spring. After the second mounting part moves downwards, the cylindrical detent pins, previously supported by the T-shaped detent blocks on its side wall, lose their support, protrude outwards, and disengage from the grooves of the locking bracket. At this point, the second spring loses its restraint, and its spring force quickly propels the small disc-shaped cover and the locking bracket upwards, thus releasing the chain attachment from the first housing and completing the separation upon unlocking. To lock the lock, the user simply pushes the locking bracket downwards, causing the second mounting part to return to its upward position.The T-shaped locking blocks on the side of the second mounting part press the cylindrical locking pins inwards into the grooves of the connector to create a locking mechanism. Simultaneously, the second spring is compressed to store energy, thus completing the locking process. This arrangement allows the connector to extend automatically after unlocking, eliminating the need for manual pulling and insertion. Operation is more convenient in situations such as rain or when wearing gloves. Furthermore, the simple and durable design effectively improves operating efficiency and user experience.

Specific embodiments

[0014] The technical solutions in the embodiments of the invention are described below in conjunction with the accompanying drawings, and it is clear that the described embodiments represent only a portion of the embodiments of the invention and not all embodiments. Based on the embodiments in the invention, all other embodiments that a person skilled in the art could achieve without inventive activity fall within the scope of protection of the invention.

[0015] As in Fig. As shown in Figures 1 to 5, a novel locking cylinder housing comprises a first housing 1, wherein a hollow tube 16 is mounted inside the first housing 1, wherein a first mounting part 2 is mounted inside the hollow tube 16, and wherein a locking cylinder 3 is movably arranged inside the first mounting part 2, a rotary disc 4 is movably arranged on the outer surface of the first mounting part 2, wherein a first spring 5 is fixedly attached to the top of the first mounting part 2, a second mounting part 6 is fixedly arranged on the side of the first spring 5 facing away from the first mounting part 2, wherein a plug-in part 7 is mounted on the top of the second mounting part 6, wherein a second spring 8 is fixedly attached to the inner bottom wall of the plug-in part 7, and wherein a small disc-shaped cover 9 is fixedly attached to the top of the second spring 8.and wherein a cylindrical locking pin 11 is arranged on each of the left and right side walls of the plug-in part 7; wherein a space for receiving the plug-in angle 10 is provided on the top of the small disc-shaped cover 9, wherein the second housing 15 is fixedly arranged on each of the top and bottom of the first housing 1, and the second housing 15 is provided as a hollow cylindrical structure that can receive the plug-in angle 10, the chain fastening part 12 and the chain element 13.

[0016] As in Fig. As shown in Figure 1, a guide for inserting the key is provided by a connection opening in the outer wall of the first housing 1, which is flush with the lock cylinder 3. This allows the user to quickly align the key with the lock cylinder 3, even in difficult situations such as darkness or when wearing gloves and having limited visibility. The dimensions of this connection opening precisely match the end of the lock cylinder 3, effectively preventing the key from getting stuck or jammed during insertion and removal.

[0017] As in Fig. As shown in Figure 1, the key rotates the entire lock cylinder 3 by providing the rotary disc 4, whereby the outer projections of the lock cylinder 3 set the rotary disc 4 into rotation.

[0018] As in Fig. As shown in Figure 3, the second assembly part 6 comprises a disk body 601, two T-shaped locking blocks 602, and a concave block 603. The disk body 601 is fixedly attached to the top of the first assembly part 2, and the two T-shaped locking blocks 602 are fixedly attached to the top of the disk body 601. The concave block 603 is fixedly attached to the underside of the disk body 601, and the rotary disk 4 is designed to fit the concave block 603. The two T-shaped locking blocks 602 are arranged axially symmetrically to the central axis of the disk body 601. Their projecting ends extend toward the inside of the plug-in part 7 and correspond exactly to the position of the locking recess 14 formed in the side wall of the plug-in part 7. They serve to support the cylindrical locking pin 11 arranged in the locking recess 14.A limiting groove matching the outer contour of the rotary disc 4 is formed on the inner wall of the concave block 603. When the user turns the key to rotate the rotary disc 4, the rotary disc 4 can rotate the concave block 603 synchronously, thereby pulling the second mounting part 6 along the inner wall of the first housing 1 into a vertical displacement, thus supporting or releasing the cylindrical locking pin 11.

[0019] As in Fig. 3 and Fig.As shown in Figure 4, the arrangement of the groove, the chain fastening element 12, and the chain creates a groove with an inner wall in an arcuate transition that fits the outer surface of the cylindrical locking pin 11. This ensures both the stability of the locking mechanism when the cylindrical locking pin 11 is engaged and a reduction in resistance when the cylindrical locking pin 11 extends during unlocking. When the locking bracket 10 is in the locked position, the chain forms a closed annular structure that can tightly enclose the object to be locked. When the locking bracket 10 extends during unlocking, the chain, together with the chain fastening element 12, is simultaneously released from the constraint of the first housing 1, quickly freeing the object.

[0020] The operation is carried out according to the following steps: 1. The user turns the key, which rotates the entire lock cylinder 3. The outer projections of the lock cylinder 3 drive the rotary disc 4 into rotation. As the rotary disc 4 engages with the concave block 603 of the second mounting part 6, the second mounting part 6 is moved downwards and the first spring 5 is compressed. 2. After the downward movement of the second assembly part 6, the cylindrical locking pin 11, which was previously supported by the T-shaped locking blocks 602 on its side wall, loses its support, emerges to the outside and releases itself from the groove of the plug-in angle 10. At this point, the second spring 8 loses its limit. 3. The spring force of the second spring 8 quickly drives the small disc-shaped cover 9 and the plug-in angle 10 upwards, whereby the chain fastening part 12 exits the first housing 1 and the unlocking and separation process is completed. 4. Finally, the user presses the locking bracket 10 downwards and turns the key back to the locked position. The lock cylinder housing drives the rotary disc 4, releasing the limit of the second mounting part 6 so that it can return to its upward position. Pressing down the locking bracket 10 and raising the second mounting part 6 work together: The T-shaped detent blocks 602 on the side wall of the second mounting part 6 push the cylindrical detent pin 11 inwards so that it re-engages in the groove of the locking bracket 10 and creates a limit. At the same time, the second spring 8 is compressed to absorb the energy, and the locking process is complete.

[0021] In summary, with this novel lock cylinder housing, the user turns the key to unlock it, causing the rotary disc 4 to rotate synchronously. Since the rotary disc 4 is designed to fit the concave block 603 of the second mounting part 6, it causes the second mounting part 6 to move downwards and compresses the first spring 5. After the downward movement of the second mounting part 6, the cylindrical detent pins 11, which were previously supported by the T-shaped detent blocks 602 on its side wall, lose their support, protrude outwards, and disengage from the grooves of the locking bracket 10. At this point, the second spring 8 loses its restraint, and its spring force quickly drives the small disc-shaped cover 9 and the locking bracket 10 upwards, causing the chain fastening part 12 to exit the first housing 1 and completing the separation upon unlocking.To lock, the user simply presses the mounting bracket 10 downwards, causing the second mounting part 6 to return upwards. The T-shaped locking blocks on the side wall of the second mounting part 6 press the cylindrical locking pins 11 inwards into the grooves of the mounting bracket 10 to create a locking mechanism. Simultaneously, the second spring 8 is compressed to store energy, thus completing the locking process. This design ensures automatic extension of the mounting bracket 10 after unlocking, eliminating the need for manual insertion and retraction. Operation is more convenient in situations such as rain or when wearing gloves. Furthermore, the design is characterized by its simplicity and durability, effectively improving usability and the user experience.
