Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric control locks for cabinets, and in particular to an electric control lock for a cabinet. Background Art
[0002] The electric lock is a mechanical lock device controlled by a relay. It has formed a series of products with different structures, including electric bolt locks (anode locks), cathode locks (electric locks), magnetic locks, electric locks, etc. The terminal of the electric lock is actually an electromagnet, which controls a simple mechanical device to open and close the door. However, the action of the electromagnet is through a series of instructions. When it cannot be controlled, first measure the voltage input to the electromagnet, and at the same time input the door opening and closing instructions (some are electromagnetic cards, and some are passwords) to see if the voltage changes. If there is a change, but the electromagnet does not move, the fault is the electromagnetic control part, which should be repaired or replaced, otherwise it is a control part failure.
[0003] Although the existing electric locks can achieve the purpose of automatic unlocking, in actual use, the structure is complicated, and the unlocking is mainly controlled by electromagnetic control devices, and the voltage input to the magnet needs to be measured. If the electromagnetic control device fails, it cannot be opened quickly, so a cabinet electric lock is needed to solve the above problems. Utility Model Content
[0004] The utility model aims to solve the shortcomings in the prior art and provides an electric control lock for a cabinet.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an electric cabinet lock, including a lock, a lock hole is opened on one side of the outside of the lock, a lock head is clamped inside the lock hole, a small motor is clamped on one side of the inside of the lock, the bottom end of the small motor is transmission-connected to an output end, the outside of the output end is provided with teeth, the bottom bolt of the lock near the small motor side is connected to a stake, and the top of the stake is movably connected to a rotating disk.
[0006] Preferably, the outside of the rotating disk is provided with teeth, and the teeth on the outside of the rotating disk and the teeth on the outside of the output end head are meshed with each other and adapted to each other.
[0007] Preferably, a threaded shaft is connected to the top end of the rotating disk, the threaded shaft and the rotating disk are integrated, and an external thread of the threaded shaft is connected to a pressing sheet.
[0008] Preferably, the pressing plate is in an L-shape, the pressing plate is slidably connected to the inside of the lock, an upper hook block is connected to the internal pin of the lock, and the end of the upper hook block passes through the pressing plate.
[0009] Preferably, a pull opening is provided at the front end of the upper hook block, an inner lock core is connected to a pin near the lock opening in the lock, and the pull opening at the front end of the upper hook block and a side corner of the inner lock core are engaged with each other.
[0010] Preferably, a groove is provided in the middle of the inner lock core, the inner lock core is in a U-shape, and the front end of the lock head is inserted into the groove in the middle of the inner lock core.
[0011] Preferably, a mounting block is connected to a middle bolt in the lock, a side spring of the mounting block is connected to an elastic plate, and a side edge of the elastic plate fits with a rear end of the inner lock core.
[0012] Beneficial Effects
[0013] When the lock is unlocked, the output terminal at the bottom is controlled by a small motor to rotate counterclockwise. The clockwise rotation of the output terminal will drive the rotating disk to rotate clockwise. The rotating disk rotates clockwise, and the external pressure plate will drop with the rotation. During the descending process of the pressure plate, the end of the upper hook block will be pressed down. At this time, the front end of the upper hook block will be tilted up. After tilting up, the upper hook block cannot hook the inner lock core. Since there is no limiting force of the upper hook block, the inner lock core cannot give squeezing force to the elastic plate alone, so the elastic plate will pop out and bounce the inner lock core down. There is a "6"-shaped limit block close to the bottom of the inner lock core, which can limit the inner lock core to prevent excessive rebound. After the inner lock core rotates back to the normal position, it will collide with the lock mouth of the lock, so the lock head therein will be loosened and pop out of the lock mouth.
[0014] In the utility model, the lock can be unlocked directly by using a small motor. The locking is achieved by hooking the inner lock core with the upper hook block, and the unlocking is achieved by indirectly controlling the upper hook block to be pushed up and loosened by the motor, so that the elastic plate pops out and pushes the inner lock core to one side to return to the center and unlock it. This solves the problem that the existing lock has a complex structure and is mainly unlocked by an electromagnetic control device, and it is also necessary to measure the voltage input to the magnet. If the electromagnetic control device fails, the lock cannot be opened quickly. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.
[0023] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:
[0025] Reference Figure 1-5 A cabinet electric lock comprises a lock 1, a lock opening 14 is provided on one side of the outside of the lock 1, a lock head 2 is clamped inside the lock opening 14, a small motor 8 is clamped on one side of the inside of the lock 1, an output terminal 11 is transmission-connected to the bottom end of the small motor 8, a tooth pattern is provided on the outside of the output terminal 11, a stake 10 is bolted to the bottom of the lock 1 near the small motor 8, and a rotating disk 9 is movably connected to the top of the stake 10.
[0026] This device mainly provides an indirect trigger lock structure. The specific style of the lock head 2 in this utility model is selected according to actual conditions, and it is necessary to ensure that the end of the lock head 2 can be inserted into the groove in the middle of the inner lock core 5 through the lock port 14.
[0027] The outside of the rotating disk 9 is provided with teeth, and the teeth on the outside of the rotating disk 9 and the teeth on the outside of the output end head 11 are meshed with each other and adapted to each other.
[0028] The top end of the rotating disk 9 is connected with a threaded shaft 12 , the threaded shaft 12 and the rotating disk 9 are integrated, and the external thread of the threaded shaft 12 is connected with a pressing piece 13 .
[0029] The pressing plate 13 is L-shaped and is slidably connected to the interior of the lock 1 . The internal pin of the lock 1 is connected to the upper hook block 3 , and the end of the upper hook block 3 passes through the pressing plate 13 .
[0030] A pull opening 4 is provided at the front end of the upper hook block 3, and an inner lock core 5 is connected to a pin near the lock opening 14 in the lock 1. The pull opening 4 at the front end of the upper hook block 3 and one side corner of the inner lock core 5 are engaged with each other, and both will move through the pin connected in the middle when moving.
[0031] A groove is provided in the middle of the inner lock core 5 , and the shape of the inner lock core 5 is U-shaped. The front end of the lock head 2 is inserted into the groove in the middle of the inner lock core 5 , and the front end of the lock head 2 is highly adapted to the groove in the middle of the inner lock core 5 .
[0032] A mounting block 7 is bolted to the middle of the lock 1 , and a spring is connected to an elastic plate 6 on one side of the mounting block 7 . The side of the elastic plate 6 fits with the rear end of the inner lock core 5 .
[0033] In the initial state, that is, the locked state, the upper hook block 3 will hook the corner of one side of the inner lock core 5 through the pull mouth 4. After the inner lock core 5 is hooked, the middle groove will face upward, the inner lock core 5 will be close to the vertical state, and the side of the inner lock core 5 will squeeze the elastic plate 6 into the mounting block 7. This is the complete state and complete steps of locking. Specific embodiment 2:
[0035] Reference Figure 1-5 When unlocking is required, the output terminal 11 at the bottom is controlled by the small motor 8 to rotate counterclockwise. The clockwise rotation of the output terminal 11 will drive the rotating disk 9 to rotate clockwise. The rotating disk 9 rotates clockwise, and the external pressing piece 13 will descend with the rotation. During the descent of the pressing piece 13, the end of the upper hook block 3 will be pressed down. At this time, the front end of the upper hook block 3 will be tilted. After tilting, the upper hook block 3 cannot hook the inner lock core 5. Due to the lack of the limiting force of the upper hook block 3, the inner lock core 5 cannot give the elastic plate 6 an extrusion force alone, so the elastic plate 6 will pop out and bounce the inner lock core 5 down. At this time, the inner lock core 5 will return to the attached Figure 4 In the state, there is a "6"-shaped limit block close to the bottom of the inner lock core 5, which can limit the inner lock core 5 to prevent excessive rebound. After the inner lock core 5 turns back to the normal position, it will collide with the lock port 14 of the lock 1, so the lock head 2 will be loosened and pop out of the lock port 14.
[0036] In short, the working principle of the lock 1 is that the upper hook block 3 hooks the inner lock core 5 for locking, and the upper hook block 3 is released for unlocking, so that the elastic plate 6 pops out and pushes the inner lock core 5 to one side, so that it returns to the center and is unlocked.
[0037] In summary:
[0038] 1. This device mainly provides an indirect trigger lock structure. The specific style of the lock head 2 in this utility model is selected according to the actual situation. It is necessary to meet the requirement that the end of the lock head 2 can be inserted into the groove in the middle of the inner lock core 5 through the lock mouth 14. In the initial state, that is, the locked state, the upper hook block 3 will hook the corner of one side of the inner lock core 5 through the pull mouth 4. After the inner lock core 5 is hooked, the middle groove will face upward, the inner lock core 5 will be close to the vertical state, and the side of the inner lock core 5 will squeeze the elastic plate 6 into the mounting block 7. This is the complete state and complete steps of locking.
[0039] 2. When unlocking is required, the output terminal 11 at the bottom is controlled by the small motor 8 to rotate counterclockwise. The clockwise rotation of the output terminal 11 will drive the rotating disk 9 to rotate clockwise. The rotating disk 9 rotates clockwise, and the external pressing piece 13 will descend with the rotation. During the descent of the pressing piece 13, the end of the upper hook block 3 will be pressed down. At this time, the front end of the upper hook block 3 will be tilted. After tilting, the upper hook block 3 cannot hook the inner lock core 5. Due to the lack of the limiting force of the upper hook block 3, the inner lock core 5 cannot give the elastic plate 6 an extrusion force alone, so the elastic plate 6 will pop out and bounce the inner lock core 5 down. At this time, the inner lock core 5 will return to the attached Figure 4 In the state, there is a "6"-shaped limit block close to the bottom of the inner lock core 5, which can limit the inner lock core 5 to prevent excessive rebound. After the inner lock core 5 turns back to the normal position, it will collide with the lock port 14 of the lock 1, so the lock head 2 will be loosened and pop out of the lock port 14.
