Description

Technical Field

[0001] The utility model belongs to the technical field of locking mechanisms, and more specifically, relates to a locking mechanism. Background Art

[0002] Construction trucks are the backbone of a construction project, significantly reducing manpower and accelerating construction progress. However, they operate in harsh environments, which can lead to a large amount of foreign matter clinging to the vehicle's body. This can make it difficult to open the doors and even damage the locking mechanism, severely impacting the vehicle's usability.

[0003] Damage to the aforementioned locking mechanism primarily involves blockage of the keyhole and deformation of the key body. To address these issues, existing methods utilize a key with a protective cover to shield the key body and keyhole, preventing blockage. However, while the protective cover of existing locking mechanisms is structurally stable, it fails to protect the key body and keyhole when the key body is not inserted into the keyhole, potentially leading to blockage and deformation of the key body. This makes the locking mechanism unsuitable for use in harsh environments, such as those found on construction vehicles. Consequently, existing locking mechanisms still fail to address these issues and require further improvement. Utility Model Content

[0044] Reference Figure 1-4 , an embodiment of the utility model provides a locking mechanism, comprising a key assembly and a locking assembly;

[0045] The key assembly includes a key body 1 and a protective sleeve configured to be foldable or stretchable along the key body 1. The key body 1 is embedded in the protective sleeve, and a plurality of first push rods 2 are provided inside the protective sleeve.

[0046] The locking assembly includes a lock body 3 having a keyhole and a protective cover sleeved over the keyhole. The protective cover includes a cover plate 4 having a through slot 41, a plurality of second push rods 5, and a limiting ring 6. The cover plate 4 has a plurality of limiting slots 42 evenly distributed along its circumference. Each of the plurality of second push rods 5 is configured to extend into each of the plurality of limiting slots 42 in a one-to-one correspondence, and the lower end of each second push rod 5 is connected to the limiting ring 6.

[0047] Each of the first push rods 2 can push each of the second push rods 5 downward in a one-to-one correspondence, so as to adjust the angle of the through slot 41 so that the key body 1 can extend into the keyhole.

[0048] In one embodiment, the protective sleeve is divided into a sleeve handle 7, a sleeve body 8 and a fastener from top to bottom. The fastener is used to seal the sleeve body 8 when the key body 1 is idle.

[0049] In one embodiment, the handle 7 has an open area 71 extending through the wall thereof, which is used to connect the handle to an external hanging ring. Specifically, after the external hanging ring is connected to the through slot, it can be used to hang keys at a designated location or connect to other hanging accessories for easy carrying by the user.

[0050] In a specific embodiment, the distance between each first push rod 2 and the sleeve handle 7 is greater than the distance between the lower end of the key body 1 and the sleeve handle 7, so that each first push rod can contact the cover plate before the key body.

[0051] In a specific embodiment, the sleeve 8 is a cylindrical structure made of silicone or PVC. Of course, it should be appreciated that the sleeve can also be made of other materials, such as cowhide, and the present invention is not limited thereto. Any material that can achieve the same technical effect as the present invention is also protected by the present invention.

[0052] In a specific embodiment, when the key body 1 is inserted into the keyhole, the sleeve 8 is in a folded state and covers the circumference of the keyhole.

[0053] In a specific embodiment, the fastener includes a first magnetic strip 9 and a second magnetic strip 10 that are arranged opposite to each other and have opposite magnetic properties. Specifically, when the key body is not in the keyhole structure, the first magnetic strip and the second magnetic strip can attract each other, causing the lower end of the sleeve to be in a retracted state, thereby sealing the sleeve and fully wrapping the key body to achieve a better protective effect.

[0054] In one embodiment, the lower end of each second push rod 5 is provided with an elastic component for extending into each limiting groove.

[0055] In a specific embodiment, the elastic component includes an inner rod 11 and a spring 12 sleeved on the inner rod 11 . The upper end of the inner rod 11 extends into each second push rod 5 , and the lower end thereof is connected to the limiting ring 6 .

[0056] Specifically, when each first push rod is separated from each limit slot, each second push rod can move upward under the action of the spring to restore the deformation force, thereby extending into each limit slot, and the protective cover is embedded in the mounting equipment such as the car door in actual application to prevent the protective cover from falling.

[0057] In one embodiment, the lower end of the lock body 3 is provided with a plurality of connection posts 13 for connecting with external devices.

[0058] When using the locking mechanism of the present invention, the locking assembly can be first installed on a mounting device such as a vehicle door, and then the key assembly can be manually placed on the protective cover so that each first push rod is inserted into each limiting groove one by one, each second push rod is pushed downward, and then the cover is rotated until the key hole is completely exposed through the through groove. Then, the key body is inserted into the key hole. At this time, as the key body is inserted, the cover body gradually folds until the key body is fully inserted into the key hole, and the vehicle door can be opened. When the key body is pulled out, the cover body gradually stretches, and each first push rod can be pulled upward. The end of the key body is used to drive the cover plate to rotate so that the through groove blocks the key hole. Then, the first magnetic strip can be attached to the second magnetic strip to close the cover body.

[0059] The locking mechanism proposed by the present invention is provided by providing a key body and a protective sleeve configured to be folded or stretched along the key body, and a plurality of first push rods are provided inside the protective sleeve, and then a lock body with a keyhole and a protective cover mounted on the keyhole are provided, the protective cover includes a cover plate with a through groove, a plurality of second push rods and a limiting ring, a plurality of limiting grooves are evenly distributed along the circumference of the cover plate, each of the plurality of second push rods is configured to be able to extend into each of the plurality of limiting grooves one by one, and the lower end of each second push rod is connected to the limiting ring; each of the plurality of first push rods can push each second push rod downward one by one to adjust the angle of the through groove so that the key body can extend into the keyhole.

[0060] Therefore, compared with the existing locking mechanism, the locking mechanism of the present invention can shield the key body and the keyhole when they are combined and separated, so as to achieve long-term protection for both, thereby effectively reducing the probability of keyhole blockage and key body deformation, and thus facilitating use in harsh environments such as the application environment of engineering vehicles.

[0061] In addition, the locking mechanism of the present invention can also be used in other equipment or scenarios besides engineering vehicles and their application environments, and can also achieve corresponding effects.

[0062] Although one or more embodiments of the present invention have been described above, it should be understood by those skilled in the art that the present invention can be implemented in any other form without departing from its spirit and scope. Therefore, the embodiments described above are illustrative and not restrictive, and many modifications and substitutions will be apparent to those skilled in the art without departing from the spirit and scope of the present invention as defined in the appended claims.
