Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically to a lock, a lock mounting structure, and a box-type folding bed using the structure. Background Technology

[0002] Folding beds can be folded up to reduce space usage, but existing folding beds lack storage functionality, requiring items to be placed separately, which still takes up space. Therefore, we have developed a box-type folding bed, comprising two box shells. A first bed board is hinged to the box shells, a second bed board is hinged to the free end of the first bed board, a first support plate and a second support plate are hinged to the back of the second bed board, and an auxiliary support plate is hinged to the back of the first support plate.

[0003] When in use, this box-type folding bed can unfold its first and second bed boards. The unfolded first and secondary support boards support the second bed board, keeping it flat and transforming it into a flat bed. The unfolded second support board supports the second bed board, raising its head and transforming it into a beach chair. After use, the secondary support board can be flipped to the back of the first support board, then the first and second support boards to the back of the second bed board, and finally the second bed board to the back of the second bed board. The first bed board is then pressed against the inside of the box shell, and the two shells are closed, transforming the box-type folding bed into a suitcase. Because the inside of the suitcase has cavities for storing items, this box-type folding bed also has a storage function.

[0004] To achieve locking between the first bed board and the box shell, the first support plate and the second bed board, and the second support plate and the second bed board, locks are required. A lock installation structure needs to be designed to install the locks on the plates. Existing lock structures are relatively complex, and the assembly of locks often requires bolt fastening. Existing lock installation structures also use bolt fastening, making the assembly and installation of locks quite cumbersome. Utility Model Content

[0005] The purpose of this utility model is to provide a lock, a lock installation structure, and a box-type folding bed using the above structure to address the above problems, thereby solving the problem of cumbersome lock assembly and installation in the prior art.

[0006] To achieve the above objectives, this utility model discloses a lock, which includes a lock box with a lock cavity. A sliding lever is installed within the lock cavity. The lever has a lever part and a locking tongue at its front end. The front end of the lock box has a first mounting opening for inserting the lever into the lock cavity. A spring is installed inside the lock box, positioned between the lock box and the lever, exerting a forward force on the lever. A limiting guide hole is provided on the bottom wall of the lock box, and a limiting guide block is provided on the bottom surface of the lever. The limiting guide block enters the limiting guide hole to prevent the lever from dislodging from the lock cavity. With this structure, lock assembly is simple: just insert the spring into the lock box, place the lever into the lock cavity, and allow the limiting guide block to enter the limiting guide hole. Lock assembly is convenient and quick.

[0007] Furthermore, the actuating part is a groove on the top surface of the lever, and the top wall of the lock box is provided with a first clearance hole for exposing the groove. With the above structure, the groove allows a finger to be inserted to actuate the lever, and the first clearance hole exposes the groove, facilitating operation.

[0008] Furthermore, the rear end face of the lever and / or the rear wall of the lock box are provided with positioning protrusions for the spring to be fitted into. With the above structure, the positioning protrusions are used to fit the spring and limit the spring to a set position.

[0009] Furthermore, a connecting hole is provided on the top or bottom wall of the lock box near the rear wall. With the above structure, the connecting hole is used for ventilation between the lock cavity located behind the lever and the outside of the lock box. In addition, the spring can also be installed and replaced through the connecting hole.

[0010] This utility model also discloses a lock mounting structure, including a plate on which the aforementioned lock is mounted.

[0011] In the first type of lock mounting structure, a first mounting chamber is provided on one side of the plate. The rear of the first mounting chamber has a second mounting opening for inserting the lock. A second locking block is provided on the bottom wall of the first mounting chamber, and a locking hole is provided on the top or bottom wall of the lock box. The second locking block engages with the locking hole to prevent the lock from dislodging from the first mounting chamber. This lock mounting structure is suitable for use on thicker plates, such as the first bed board of a box-type folding bed.

[0012] Furthermore, the second locking block is an elastic strip structure integral with the bottom wall of the first mounting chamber, with the free end of the elastic strip extending forward and entering the locking hole. With this structure, the elastic strip has a large elastic deformation capacity, facilitating the installation of the lock body.

[0013] Furthermore, the plate is provided with a second clearance hole for exposing the actuating part of the lock. With the above structure, the second clearance hole is used to expose the actuating part of the lock, which facilitates operation.

[0014] In the second type of lock mounting structure, a second mounting chamber is provided on one side of the plate, and the chamber wall of the second mounting chamber forms the lock box of the lock. This lock mounting structure is suitable for application on thinner plates, such as on the first support plate and the second support plate of a box-type folding bed.

[0015] This utility model also discloses a box-type folding bed, including a box shell, a first bed board hinged to the box shell, a second bed board hinged to the free end of the first bed board, a first support plate and a second support plate hinged to the back of the second bed board, and a secondary support plate hinged to the back of the first support plate. The first bed board adopts the first type of lock mounting structure described above, and the lock of this lock mounting structure is used for locking between the first bed board and the box shell; the first support plate and / or the second support plate adopt the second type of lock mounting structure described above, and the lock of the lock mounting structure adopted on the first support plate is used for locking between the first support plate and the second bed board, and the lock of the lock mounting structure adopted on the second support plate is used for locking between the second support plate and the second bed board. With the above structure, the locks on the second bed board, the first support plate, and the second support plate are installed by plugging in, without the need for other fasteners, making installation convenient and quick.

[0016] In summary, the beneficial effects of this utility model are as follows: This utility model provides a lock and improves the lock installation structure, simplifying the lock structure. The lock is assembled using a plug-in method and installed on the plate using a plug-in method, making the assembly and installation of the lock relatively convenient. The lock and the housing in this utility model are preferably made of plastic, thus eliminating the need for metal fasteners during assembly and installation. Attached Figure Description
