Description

Technical Field

[0001] The utility model relates to the technical field of crescent locks, specifically to a novel crescent lock. Background Art

[0002] At present, many doors and windows use crescent locks for easy closing. Its structure is composed of a handle, a lock hook, a base and a cover. When in use, rotate the handle to drive the lock hook to rotate and rotate it to the lock hook of the door and window on the other side, thereby locking the door and window.

[0003] When using existing crescent locks, in order to facilitate users to install and fix them, the mounting base will have mounting holes, and the mounting holes are exposed on the outside. Long-term use may cause dust and rainwater to enter the mounting holes, causing corrosion and damage to the internal screws, which is very inconvenient when disassembly is needed, making it inconvenient for users to use. Utility Model Content

[0004] The utility model aims to provide a novel crescent lock to solve the problem in the background art that the screw holes of the currently used crescent locks are exposed on the outside, which easily causes erosion and damage to the screws.

[0005] To achieve the above object, the utility model provides the following technical solutions: a new type of crescent lock, comprising: a mounting seat and a mounting hole, the top of the mounting seat is connected to a handle through a rotating shaft, one side of the handle is connected to a lock hook, and the mounting hole is opened on the top of the mounting seat;

[0006] One side of the mounting hole is connected with a movable plate via a rotating shaft, and one side of the movable plate is installed with a protrusion.

[0007] Preferably, a docking block is installed on the top of the protrusion, and a limiting block is sleeved on the outer side of the docking block.

[0008] Preferably, a telescopic block is connected to the bottom of the limiting block, and a positioning block is sleeved on the bottom of the telescopic block.

[0009] Preferably, a telescopic spring is connected between the telescopic block and the groove of the positioning block.

[0010] Preferably, a movable block is connected through one side of the handle, and a pressing plate is connected to the bottom of the movable block.

[0011] Preferably, the bottom of the pressure plate is connected to a sliding block via a sliding groove, and the bottom of the sliding block is connected to a push rod.

[0012] Preferably, a fixing block is sleeved on the end of the push rod, and a movable spring is connected between the push rod and the groove of the fixing block.

[0013] Compared with the prior art, the beneficial effect of the utility model is that when the new crescent lock is in use, the movable plate can be rotated by the rotating shaft to rotate the movable plate to one side of the mounting hole, and then the telescopic block is loosened. The telescopic block is reset by the telescopic spring inside the positioning block and moves downward, and the limit block is sleeved on the outer side of the docking block. At this time, the movable plate can be limited, and the screws in the mounting hole can be shielded by the movable plate, so that the screws are not easily damaged by erosion by rainwater. This is the use feature of the new crescent lock.

[0014] 1. When using this new crescent lock, the movable plate can be rotated to one side of the mounting hole by rotating the shaft, and the limit block can be sleeved on the outside of the docking block. At this time, the movable plate can be fixed, making it difficult for dust and rainwater to enter the screws in the mounting hole and damage the screws, thereby increasing the service life of the entire crescent lock.

[0015] 2. This new type of crescent lock, when the handle hits the door frame, causes the movable block to be squeezed and move toward the inside of the handle, and squeezes the pressure plate. When the pressure plate is squeezed, it will squeeze the push rod, causing the push rod to move toward the inside of the fixed block and squeeze the movable spring. At this time, the movable spring can buffer the movable block to avoid excessive impact force and damage to the handle. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 and Figure 2 The utility model provides a technical solution: a new type of crescent lock, comprising: a mounting seat 1 and a mounting hole 4, the top of the mounting seat 1 is connected with a handle 2 through a rotating shaft, one side of the handle 2 is connected with a lock hook 3, and the mounting hole 4 is opened on the top of the mounting seat 1;

[0023] A movable plate 5 is connected to one side of the mounting hole 4 through a rotating shaft, a protrusion 6 is installed on one side of the movable plate 5, a docking block 7 is installed on the top of the protrusion 6, a limiting block 8 is sleeved on the outer side of the docking block 7, a telescopic block 9 is connected to the bottom of the limiting block 8, a positioning block 10 is sleeved on the bottom of the telescopic block 9, a telescopic spring 17 is connected between the grooves of the telescopic block 9 and the positioning block 10, the docking block 7 is inserted into the limiting block 8 by a size matching the docking block 7, and the movable plate 5 forms a rotating structure with the mounting seat 1 through the rotating shaft.

[0024] When the locking nut 5 is unlocked, the locking nut 5 is unlocked, and the locking nut 5 is unlocked, so that the locking nut 5 can be unlocked.

[0025] See also Figure 1 , Figure 2 and Figure 4 It can be seen that when in use, the movable plate 5 can be rotated to the outside of the mounting hole 4, so as to shield the mounting hole 4 and prevent a large amount of rainwater from entering the mounting hole 4 and corroding the screws, making the entire crescent lock inconvenient to disassemble and assemble.

[0026] A movable block 11 is connected through one side of the handle 2, a pressure plate 12 is connected to the bottom of the movable block 11, a sliding block 13 is connected to the bottom of the pressing plate 12 through a sliding groove, a push rod 14 is connected to the bottom of the sliding block 13, a fixed block 15 is sleeved on the end of the push rod 14, a movable spring 16 is connected between the push rod 14 and the groove of the fixed block 15, and a telescopic structure is formed between the push rod 14 and the fixed block 15 through the movable spring 16.

[0027] In specific implementation, when the new crescent lock is in use, when the handle 2 is hit, it can move into the groove of the handle 2 through the movable block 11, and at the same time, the movable block 11 will squeeze the pressure plate 12, and the pressure plate 12 will move into the handle 2 when squeezed, and squeeze the slider 13, and the slider 13 is connected to the top rod 14, and the end of the top rod 14 is inserted with a fixed block 15 through a movable spring 16, so that the slider 13 squeezes the top rod 14 and makes the top rod 14 move into the fixed block 15, and the slider 13 at one end of the top rod 14 will slide along the pressure plate 12, at this time, the cooperation of the top rod 14 and the movable spring 16 can play a buffering role on the movable block 11, so as to prevent the doors and windows from sliding with excessive force, causing the handle 2 to hit the door frame and cause damage to the handle 2.

[0028] See also Figure 1 and Figure 3 It can be seen that when the handle 2 is hit, the movable block 11 can squeeze the push rod 14, and the push rod 14 will squeeze the movable spring 16, causing the push rod 14 to contract, thereby playing a buffering role for the handle 2 and avoiding damage to the handle 2.
