Description

Technical Field

[0001] This utility model relates to a locking device for a spare tire cover lock and a spare tire cover lock. Background Technology

[0002] In modern cars, the spare tire, as an essential component for emergency use, is typically installed and secured at the rear of the vehicle. To prevent the spare tire from falling off or being stolen, a spare tire cover is often used to cover and secure it. To further enhance protection, spare tire covers are usually equipped with locking devices to control the cover's secure position and prevent unauthorized opening.

[0003] However, the locking devices in the prior art have the following shortcomings:

[0004] Traditional locking mechanisms often consist of multiple independent connecting parts, which are prone to loosening or misalignment during frequent use or vehicle vibration, affecting the locking effect and durability.

[0005] Existing sliding structures often lack precise limiting and adjustment mechanisms. The sliding parts are prone to inaccurate positioning, which can cause the hook to fail to properly engage with the locking groove, affecting the locking effect of the spare tire cover. Utility Model Content

[0006] The primary objective of this invention is to provide a locking device for a spare tire cover lock that is structurally sound and easy to adjust.

[0007] The second objective of this utility model is to provide a spare tire cover lock with a reasonable structure and convenient adjustment.

[0008] The primary objective of this invention is achieved as follows:

[0009] A locking device for a spare tire cover lock, the locking device comprising a sliding member, a connecting plate, a bolt, and a nut;

[0010] The sliding component includes a sliding plate, an upper side plate, and a rear side plate. The front end of the sliding plate is provided with a hook. The upper side plate is respectively provided on both sides of the surface of the sliding plate to form a locking tongue groove. The top of the upper side plate and the top of the upper side plate form an entrance to the locking tongue groove. The entrance size of the locking tongue groove is smaller than the inner cavity size of the locking tongue groove. The rear side plate is provided at the rear end of the sliding plate and has a second through hole.

[0011] The connecting plate is provided with a first through hole, and the connecting plate is also provided with a slot communicating with the first through hole, and the nut is placed in the slot;

[0012] The head of the bolt rests against the sliding member, and the tail of the bolt passes through the second through hole, the first through hole, and the nut and extends into the slot.

[0013] Rotate the nut to adjust the position of the adjusting bolt, thereby adjusting the position of the sliding component.

[0014] This locking device achieves precise adjustment of the sliding component's position through the cooperation of the sliding component with bolts, nuts, and connecting plates. It features a compact structure and high reliability. The sliding component is fixedly connected to the bracket by bolts. Users only need to rotate the nut to control the forward and backward movement of the bolt, thereby driving the sliding component to achieve linear adjustment. This allows the hook to accurately enter or exit the locking groove, effectively improving the efficiency and stability of locking or unlocking.

[0015] Furthermore, the integrated design of the sliding component, combining the slide plate, upper side plate, and rear side plate, not only simplifies the assembly process but also improves overall strength and resistance to deformation. The inlet size of the latch groove is smaller than the inner cavity size, ensuring the latch is securely embedded after insertion, enhancing locking reliability and preventing accidental dislodgement due to vibration.

[0016] The primary objective of this utility model can also be achieved by the following technical measures:

[0017] Furthermore, the upper side plate is an L-shaped upper side plate, and the lateral portion of the L-shaped upper side plate and the lateral portion of another L-shaped upper side plate stand opposite each other to form the entrance of the locking tongue groove.

[0018] The L-shaped upper side plate design forms the entrance to the latch groove with two opposing horizontal parts, resulting in a more stable structure and good guiding performance. This effectively guides the latch to smoothly insert into the latch groove, improving the accuracy and smoothness of the locking action.

[0019] This structure enhances the lateral support of the locking tongue groove, preventing the locking tongue from shaking or loosening in the locked state, and further improving the safety and reliability of the locking device.

[0020] Meanwhile, the L-shaped upper side plate design simplifies the manufacturing process of the sliding parts, facilitates one-piece molding, reduces production costs, and improves product consistency and durability.

[0021] The second objective of this utility model is achieved as follows:

[0022] A spare tire cover lock further includes a bracket, a lock cover, a lock cylinder, and a lock tongue. The lock cylinder is disposed on the lock cover, the lock tongue is a long strip-shaped lock tongue, the lock tongue is connected to the lock cylinder, the lock cylinder controls the rotation of the lock tongue, and the lock cover is rotatably disposed on the bracket.

[0023] The connecting plate is rotatably connected to the bracket, and the locking tongue groove is a long strip-shaped locking tongue groove;

[0024] The length of the elongated latch is less than the length of the entrance to the elongated latch groove, the width of the elongated latch is less than the width of the entrance to the elongated latch groove, and the length of the elongated latch is greater than the width of the entrance to the elongated latch groove.

[0025] By employing a matching structure of a long, narrow bolt and a long, narrow bolt groove, precise engagement of the bolt at the bolt groove entrance is achieved. The length and width of the bolt are rationally designed to ensure smooth insertion at the entrance and prevent loosening, thereby improving the stability and security of the lock.

[0026] In addition, the design that the length of the bolt is greater than the width of the bolt groove entrance ensures that the bolt can effectively lock into the bolt groove when it is not parallel, preventing the lock cover from being rotated open without authorization, thereby enhancing the anti-theft performance.

[0027] The beneficial effects of this utility model are as follows:

[0028] This invention relates to a locking device that achieves precise adjustment of the sliding component's position through the cooperation of a sliding component with bolts, nuts, and a connecting plate. The device features a compact structure and high reliability. The sliding component is fixedly connected to the bracket by bolts. Users only need to rotate the nut to control the bolt's forward and backward movement, thereby driving the sliding component to achieve linear adjustment. This allows the hook to accurately enter or exit the locking groove, effectively improving the efficiency and stability of locking and unlocking.

[0029] This utility model features an integrated sliding component design, combining a sliding plate, upper side plate, and rear side plate. This not only simplifies the assembly process but also improves overall strength and resistance to deformation. The inlet size of the locking tongue groove is smaller than the inner cavity size, ensuring the locking tongue is securely embedded after insertion, enhancing locking reliability and preventing accidental dislodgement due to vibration.

[0030] This invention achieves precise engagement of the bolt at the bolt groove entrance by employing a matching structure of an elongated bolt and an elongated bolt groove. The length and width of the bolt are rationally designed to ensure smooth insertion at the entrance and prevent loosening, thereby improving the stability and security of the lock.
