Description

Technical Field

[0001] The invention belongs to the technical field of locks, and particularly relates to a simple lock. Background Art

[0002] During power construction, simple houses are built. Some work needs to be done indoors and should not be disturbed by outsiders during work, or the doors need to be closed to prevent wind, dust and rain from drifting into the room, and to prevent animals from breaking in. Therefore, the doors need to be locked, so locks are usually purchased for use. After the construction is completed, the locks are discarded because they are no longer used, resulting in excessive waste. In addition, in some remote areas, since the market is far away from the construction site, it is difficult to purchase locks. Therefore, the use of homemade simple locks is both convenient and economical. Summary of the Invention

[0003] According to the relevant issues mentioned in the background technology, the present invention provides a simple lock, including a lock buckle 3 and a locking ring 4, the lock buckle 3 is connected to the second fixed block 2, the locking ring 4 is connected to the locking ring seat 5 through the locking ring shaft 6, and the locking ring seat 5 is connected to the first fixed block 1; one of the first fixed block 1 or the second fixed block 2 is fixedly connected to the door, and the other is fixedly connected to the door frame; the locking ring 4 is an integral structure symmetrically bent into an L shape, and its two ends are connected to the two ends of the locking ring shaft 6. When it is lifted clockwise along the locking ring shaft 6, the lock buckle 3 is not constrained by the locking ring 4, and the door can be opened.

[0004] Furthermore, the lock buckle 3 includes a lock rod seat 31, a lock rod 32, a limit rod seat 33, a limit rod 34 and a spring 35; the lock rod seat 31 is a cylinder with a side surface processed into a plane, which is rotatably connected to the second fixed block 2, and a through hole for installing the lock rod 32 is opened at its side plane and the intersection with the axis; the limit rod seat 33 is fixedly installed above the lock rod seat 31, and a step hole with a smaller diameter at the top and a larger diameter at the bottom is opened in the upper and lower directions; the upper and lower ends of the limit rod 34 are respectively fixed with stop blocks, which pass through the spring 35 and are installed in the step hole of the limit rod seat 33, and the spring 35 is restricted below the small step hole. When the spring 35 is in a state of no force, the stop block below the limit rod 34 contacts the side plane of the lock rod seat 31, thereby limiting the rotation of the lock rod seat 31.

[0005] Preferably, the locking rod 32 and the locking rod seat 31 are threadedly connected.

[0015] In the figure: the first fixing block 1, the second fixing block 2, the lock 3, the locking ring 4, the locking ring seat 5, the locking ring rotating shaft 6; the lock rod seat 31, the lock rod 32, the limit rod seat 33, the limit rod 34, the spring 35. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0017] Embodiment 1, please refer to the attached Figure 1, A simple lock, comprising a lock catch 3 and a locking ring 4. The lock catch 3 is connected to the second fixing block 2, and the locking ring 4 is connected to the locking ring seat 5 through a locking ring rotating shaft 6. The locking ring seat 5 is connected to the first fixing block 1. One of the first fixing block 1 or the second fixing block 2 is fixedly connected to the door, and the other is fixedly connected to the door frame. The locking ring 4 is an integral structure symmetrically bent into an L shape, and its two ends are connected to the two ends of the locking ring rotating shaft 6. When it is lifted clockwise along the locking ring rotating shaft 6, the lock catch 3 is not restricted by the locking ring 4, and thus the door can be opened.

[0018] This simple lock can fix the first fixing block 1 on the door frame and the second fixing block 2 on the door. When closing the door, the locking ring 4 drops, and its upper part naturally lies above the locking ring seat 5, and its bent part must be lower than the lock catch 3. Thus, the lock catch 3 is restricted by the locking ring 4, and the door cannot be opened. When opening the door, lift the locking ring 4 clockwise, and then the lock catch 3 is not restricted by the locking ring 4, and the door can be opened.

[0019] The components forming this simple lock can be made from locally available materials. Among them, the first fixing block 1, the second fixing block 2, and the locking ring seat 5 can be made of iron blocks, and the lock catch 3 and the locking ring 4 can be formed by bending steel bars. This simple lock can achieve the function of a door lock, does not require a key to open, has a simple and fast manufacturing process, and good economy. Installed outside the door, it can prevent animals, etc. from entering the room. When installed inside the door, it can prevent indoor work from being disturbed by outsiders.

[0020] Embodiment 2, as a specific embodiment of the above embodiment, please refer to the attached Figure 2 and 3 , The lock catch 3 includes a lock rod seat 31, a lock rod 32, a limit rod seat 33, a limit rod 34, and a spring 35. The lock rod seat 31 is a cylinder with a flat surface processed on its side. It is rotatably connected to the second fixing block 2, and a through hole for installing the lock rod 32 is provided at the intersection of its side plane and the axis. The limit rod seat 33 is fixedly installed above the lock rod seat 31, and a stepped hole with a smaller upper diameter and a larger lower diameter is provided in the vertical direction. The upper and lower ends of the limit rod 34 are respectively fixed with stop blocks. It passes through the spring 35 and is installed in the stepped hole of the limit rod seat 33, and the spring 35 is restricted below the small stepped hole. When the spring 35 is in an unloaded state, the stop block below the limit rod 34 contacts the side plane of the lock rod seat 31, thereby restricting the rotation of the lock rod seat 31.

[0021] When it is not necessary to close the door, the lock rod 32 can be rotated clockwise by 90°, then the spring 35 is compressed, and the limit rod 34 is pushed upward. Thus, no matter what position the locking ring 4 is in, the door is not locked.

[0022] Preferably, the locking rod 32 and the locking rod seat 31 are connected by a threaded fit. The threaded connection can appropriately adjust the installation position of the locking rod 32 in the through hole of the locking rod seat 31, further increasing the flexibility and adaptability.

[0023] The limiting rod 34 and the stop block above it are connected by a thread for easy installation or disassembly.

[0024] There are a pair of locking ring seats 5, and their two side surfaces are in the middle position of the locking ring 4; this structure can increase the width of the locking ring 4, and thus a larger-sized buckle structure is realized to improve the firmness after locking.

[0025] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
