Description

Technical Field

[0001] This application relates to a RV lock with multiple locking functions, belonging to the field of RV lock technology. Background Technology

[0002] RV locks are widely used in RVs and other similar facilities. They achieve locking by using a lock cylinder assembly, handle, and latch. However, on the one hand, current RV locks have a single locking mechanism; if one locking method fails, the entire lock usually needs to be replaced, resulting in high operating costs. On the other hand, they require many components, especially when multiple locking mechanisms are introduced, which also requires more components to implement the locking mechanism, leading to slower transmission efficiency and inconvenience. Utility Model Content

[0003] In view of this, this application provides a RV lock with multiple locking functions, which not only realizes multiple locking of the RV, but also reduces fixed connections, effectively avoids structural damage caused by mechanical friction, and realizes rapid response of locking relationship.

[0004] Specifically, this application is implemented through the following scheme: A RV lock with multiple locking functions includes a base, a handle, a first locking component, a latch component, a second locking component, and a locking pin. The base has a receiving area and a lock cylinder seat on its front side, and the handle is installed in the receiving area; The handle includes a connecting end and a gripping end. The connecting end is linked to the latch assembly via a connecting shaft. Between the connecting end and the gripping end, there is a first section and a second section. The first section is adapted to the side shape of the receiving area, and the second section is adapted to the bottom shape of the receiving area. The first locking component includes a lock cylinder assembly, which is installed in a lock cylinder base. The eccentric cam of the lock cylinder assembly is linked to a locking pin to control the locking pin to engage or disengage from the handle, thereby locking or unlocking the handle from the base. The second locking component includes a padlock bracket, which is located on the back side of the base. The end of the padlock bracket has a fork-shaped structure that passes through the receiving area. The handle is located inside the fork-shaped structure, and the padlock passes through the fork-shaped structure to lock the handle.

[0005] Furthermore, as a preferred option: The base protrudes to the back side to form a first bushing, and a second bushing is provided at a position corresponding to the first bushing. One end of the connecting shaft is fixedly connected to the second bushing, and the other end passes through the first bushing and is connected to the connecting end. The latch assembly is mounted on the second bushing. Rotating the handle causes the second bushing to rotate, displacing the latch assembly and thus linking the connecting end with the latch assembly. More preferably: The first bushing is provided with a stop groove one, and the second bushing is provided with a stop groove two. The stop groove one and the stop groove two are provided in correspondence to realize the rotational engagement and positioning of the two.

[0006] A first spring is fitted on the connecting shaft. When the connecting end is under force, the first spring stretches; when the connecting end is not under force, the first spring restores its deformation and drives the connecting end to reset.

[0007] The connecting shaft is connected to the connecting end via a fourth bushing: the fourth bushing has a bushing groove, the connecting end is inserted into the shaft, one end of the connecting shaft passes through the fourth bushing and has a pin hole at that end, and the connecting pin passes through the fourth bushing, the handle and the pin hole of the connecting shaft to complete the connection between the connecting shaft and the bushing groove and the connecting end.

[0008] A guide sleeve is installed inside the first bushing, and the guide sleeve extends toward the second bushing, which plays a guiding and positioning role in the installation of the first bushing and the second bushing.

[0009] The guide sleeve surface is preferably provided with a prismatic external thread to ensure that when the handle is in the unlocked state, it can be pulled out partially without affecting the connection between the first bushing and the second bushing. In this way, when the first stop groove and the second stop groove form a stop, the rotation of the first bushing and the second bushing is consistent.

[0010] A third bushing is provided on the second bushing, and the latching assembly is movably mounted on the third bushing. The third bushing and the second bushing are an integral structure.

[0011] The second bushing has a receiving cavity, which is closed at one end and open at the other end and top. The cam is slidably mounted on the receiving cavity via a seat foot. Preferably, a cam sleeve is fitted onto the cam to avoid damaging the vehicle wall. A cam seat is provided at the bottom of the cam, and the seat foot of the cam seat is embedded in the receiving cavity. The diameter of the cam seat and the seat foot is larger than the top opening, but the diameter of the seat foot does not exceed the end opening, so that the cam seat and the cam are both located above the second bushing, while the seat foot is located inside the receiving cavity.

[0012] The aforementioned latch assembly is installed in conjunction with the wall of the RV. When the handle is turned, the second bushing rotates accordingly, and the latch assembly moves away from the wall corresponding to the RV door, thus unlocking the RV. Conversely, it locks the RV.

[0013] The receiving area has a bowl-shaped structure, including a side and a bottom. The first section has two parts, which are respectively connected between the connecting end and the second section, and between the second section and the gripping end.

[0014] The locking pin is located on a pin bracket, and a cam pivot groove is provided at the bottom of the pin bracket. An eccentric cam passes through the lock cylinder seat and forms a linkage connection with the cam pivot groove. When a key is inserted into the lock cylinder assembly, it drives the lock cylinder assembly to rotate. The eccentric cam then pushes the cam pivot groove to rise and fall, causing the pin bracket to rise and fall accordingly. This, in turn, causes the locking pin to exit or enter the pin hole on the handle, thereby locking or unlocking the handle from the base. More preferably: The cam pivot groove is provided with a stop groove three on the side facing the lock cylinder seat, and a stop plate is provided on the corresponding lock cylinder assembly. The stop plate cooperates with the stop groove three to limit the rotation angle.

[0015] The pin bracket is an L-shaped structure comprising a horizontal section and a vertical section. The horizontal section is located at the top of the vertical section, the locking pin is located on the horizontal section, and the cam pivot groove is located on the side of the vertical section.

[0016] When the key turns, it causes the lock cylinder assembly to rotate. The eccentric cam on the lock cylinder assembly rotates accordingly, and the contact position between the eccentric cam and the cam pivot groove changes. This causes the pin bracket to move horizontally up and down relative to the center of rotation of the lock cylinder assembly, and the locking pin moves up and down accordingly. The locking pin either moves downward out of the pin hole or upward into the pin hole. When the locking pin enters the pin hole, the handle and the base are fixed in position by the locking pin, and the handle cannot be moved at this time. When the locking pin exits the pin hole, the handle and the base are no longer fixed, and the first locking relationship is released.

[0017] A second spring is installed between the padlock bracket and the base. The second spring is preferably a pagoda-shaped spring, with its large end located between the fork-shaped structures and its small end facing the base.

[0018] When the handle falls into the fork-shaped structure of the padlock holder, the padlock is applied to the fork-shaped structure, and the padlock holder is pulled outward, locking the handle within the closed space formed by the base, the padlock, and the fork-shaped structure, thus completing the second locking relationship. At this time, the second spring between the padlock holder and the base is in a compressed state. When the padlock is removed, the fork-shaped structure and the handle are no longer constrained by the padlock, that is, the padlock holder is no longer under force. The second spring between the padlock holder and the base returns to its original deformation, pushing the padlock holder to reset, and the second locking relationship is released.

[0019] The lock cylinder base is provided with a lock hole, and the lock cylinder assembly is inserted into the lock hole to realize its installation on the lock cylinder base.

[0020] A lock cover is provided above the lock cylinder assembly to protect it. More preferably, the lock cylinder base has a lock cover mounting hole, through which the lock cover is mounted above the lock cylinder assembly. A return spring is preferably fitted onto the bottom of the lock cover.

[0021] A rear cover plate is installed on the back of the base. Assembly slot one and assembly slot two are respectively provided on the rear cover plate at positions corresponding to the receiving area and the lock cylinder seat. The second locking component is installed in assembly slot one, and the locking pin is installed in assembly slot two. Preferably: The top of the rear cover plate is provided with a positioning groove, in which the second bushing is movably installed. The positioning groove does not affect the rotation of the second bushing with the handle, but it fixes the position of the rotation axis. The second bushing has a cylindrical structure, and the positioning groove is an arc-shaped groove that matches the shape of the outer wall, ensuring smooth rotation of the second bushing.

[0022] An assembly groove three is also provided between the assembly groove one and the assembly groove two. The assembly groove three is correspondingly provided with the locking pin to form a movement guide rail for the locking pin. Preferably, the rear cover plate protrudes towards the base to form a bracket. The end of the bracket is provided with an assembly groove three that runs vertically through the base. The locking pin is located in the assembly groove three that runs vertically through the base but is not open on all four sides. The locking pin moves up and down along the assembly groove three.
