Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of mechanical locking devices, specifically to an impact locking ejection mechanism. Background Technology
[0002] The impact-locking ejection mechanism is a mechanical structure that achieves rapid locking through external impact and unlocks and ejects through a drive component. Existing impact-locking ejection mechanisms have the following shortcomings in practical applications: Traditional mechanisms often employ a single locking claw or latch structure, which is prone to accidental unlocking when subjected to external forces such as vibration and impact. This is especially true in high-speed operating equipment or frequent start-stop scenarios, where cylindrical components may detach, affecting the normal operation of the equipment. Furthermore, it is difficult to visually determine whether the cylinder is properly locked, and insufficient impact force or positional deviation can lead to insecure locking, posing safety hazards during subsequent use. Some mechanisms also rely on manual unlocking or complex transmission structures, making it impossible to achieve rapid automated unlocking. Utility Model Content
[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides an impact locking ejection mechanism that is stable in locking, accurate in detection, fast in unlocking, and reliable in resetting.
[0004] The technical solution adopted by this utility model is as follows: This utility model provides an impact locking ejection mechanism, including a housing, the housing including a main body and a cover plate covering the main body, the cover plate having a front baffle, the front baffle having a rear baffle fixed on it by a fixing post, and also including a locking assembly and a driving assembly. The locking assembly includes claws and hooks, the claws having a locking groove for locking the cylinder, the claws having two sets, the rear baffle and the front baffle having two sets of first rotating shafts fixed between them, the two sets of claws being rotatably sleeved on the two sets of first rotating shafts respectively, the main body having a second rotating shaft fixed on it, the hook being rotatably sleeved on the second rotating shaft, the second rotating shaft having a torsion spring sleeved on it, the two ends of the torsion spring being fixed on the main body and the hook respectively, the driving assembly being used to drive the hook to rotate around the second rotating shaft, one set of claws having a slot, the hook having a locking connector at one end near the claw, when the locking connector rotates into the slot, the claw is locked, when the locking connector rotates out of the slot, the claw is unlocked.
[0005] Preferably, the drive assembly includes a motor and a connecting arm. The motor is mounted on the main body, and an unlocking block is provided on the output shaft of the motor. A support is provided inside the main body, and the connecting arm is rotatably mounted on the support. An opening is provided at the end of the hook away from the locking head, and one end of the connecting arm is inserted into the opening. A beveled protrusion is provided at the end of the connecting arm near the unlocking block, and a pressing post is provided on the unlocking block. When the pressing post presses down on the beveled protrusion, the connecting arm lifts the open end of the hook, causing the locking head to move out of the slot and releasing the lock on the claw. When the pressing post separates from the beveled protrusion, under the action of the torsion spring, the locking head end of the hook moves upward and engages in the slot, locking the claw.
[0006] Preferably, a switch box and a guide box are snapped onto the front baffle. The guide box is located above the switch box, and a switch body is provided inside the switch box. A sliding groove is provided on the guide box, and a sliding piece is slidably disposed in the sliding groove. The bottom end of the sliding piece is provided with a base plate for pressing the switch body, and a return spring is provided on the base plate. The return spring is fixed to the inner wall of the switch box. When locking the cylinder, the cylinder strikes the claw downward and closes the claw. At the same time, the cylinder presses down on the sliding piece until the pressure plate presses down on the switch body, indicating that it is locked in place. At this time, the drive connector engages in the slot to lock the claw. When unlocking the cylinder, the drive connector moves out of the slot, cancels the locking of the claw, and the cylinder is taken out upward. The sliding piece moves upward and resets under the action of the return spring.
[0007] More preferably, the slide is provided with a limiting groove, and the guide box is provided with a limiting block. The limiting block slides in the limiting groove, and the upper and lower sliding distance of the slide is limited by the limiting block and the limiting groove.
[0008] More preferably, a set of the claws is provided with a limiting protrusion, and the rear baffle is provided with a limiting plate for blocking and limiting the limiting protrusion.
[0009] More preferably, the locking components are provided in two symmetrical sets.
[0010] The beneficial effects of this utility model using the above structure are as follows: the locking mechanism has a horizontal cylinder, and the two sets of symmetrically arranged locking components can simultaneously fix both sides of the mechanism to be fixed. The locking groove fits tightly with the cylinder, and with the torsion spring and hook locking structure, the locking is firm and has strong resistance to vibration and impact. The limiting plate and the limiting protrusion cooperate to prevent the claw from rotating excessively, further improving the locking stability.
[0011] During the locking process, the cylinder presses down on the sliding plate to trigger the switch body, providing direct feedback on the locking status and avoiding insecure locking due to insufficient impact or positional deviation. The limiting structure of the sliding plate ensures triggering accuracy, providing accurate signals for subsequent locking actions and improving the overall operational reliability of the mechanism. The motor-driven unlocking block quickly rotates the hook through the connecting arm to achieve unlocking, with a rapid response.
[0012] The torsion spring provides a stable reset force for the hook, ensuring that the locking connector quickly and accurately engages in the slot after unlocking; the slider achieves automatic reset through the reset spring, which is simple in structure and has high reset accuracy.

Therefore, they should not be construed as limitations on this utility model.
[0017] like Figures 1-9 As shown, the present invention provides an impact locking ejection mechanism, including a housing 1, the housing 1 including a main body 11 and a cover plate 12 covering the main body 11, the cover plate 12 is provided with a front baffle 121, and a rear baffle 111 is fixed on the front baffle 121 by a fixing post 13, and also includes a locking component 2 and a driving component 3, the locking component 2 being symmetrically provided in two sets.
[0018] The locking assembly 2 includes claws 21 and hooks 22. Claws 21 have locking grooves 212 for locking the cylinder. Two sets of claws 21 are provided. Two sets of first rotating shafts 14 are fixed between the rear baffle 111 and the front baffle 121. The two sets of claws 21 are rotatably sleeved on the two sets of first rotating shafts 14 respectively. A second rotating shaft 15 is fixed on the main body 11. Hooks 22 are rotatably sleeved on the second rotating shaft 15. A torsion spring is sleeved on the second rotating shaft 15, and both ends of the torsion spring are fixed to the main body 11 and the hooks 22 respectively. 2. The drive assembly 3 is used to drive the hook 22 to rotate around the second rotating shaft 15. A set of claws 21 are provided with a slot 213. The end of the hook 22 near the claw 21 is provided with a locking connector 222. When the locking connector 222 rotates into the slot 213, the claw 21 is locked. When the locking connector 222 rotates out of the slot 213, the claw 21 is unlocked. A set of claws 21 are provided with a limiting protrusion 211. The rear baffle 111 is provided with a limiting plate 112 for blocking and limiting the limiting protrusion 211.
[0019] The drive assembly 3 includes a motor 31 and a connecting arm 32. The motor 31 is mounted on the main body 11, and an unlocking block 311 is provided on the output shaft of the motor 31. A support 16 is provided inside the main body 11, and the connecting arm 32 is rotatably mounted on the support 16. The end of the hook 22 away from the locking head 222 is provided with an opening 221. One end of the connecting arm 32 is inserted into the opening 221. The end of the connecting arm 32 near the unlocking block 311 is provided with a beveled protrusion 321. The unlocking block 311 is provided with a pressing post 312. When the pressing post 312 presses the beveled protrusion 321, the connecting arm 32 lifts the opening 221 end of the hook 22, causing the locking head 222 to move out of the slot 213 and release the lock on the claw 21. When the pressing post 312 separates from the beveled protrusion 321, under the action of the torsion spring, the locking head 222 end of the hook 22 moves upward and locks into the slot 213, locking the claw 21.
[0020] A switch box 122 and a guide box 124 are snapped onto the front baffle 121. The guide box 124 is located above the switch box 122. The switch body 123 is located inside the switch box 122. The guide box 124 has a sliding groove, in which a sliding piece 125 slides. The bottom end of the sliding piece 125 has a base plate for pressing the switch body 123. A return spring 126 is provided on the base plate and is fixed to the inner wall of the switch box 122. When locking the cylinder, the cylinder strikes the claw 21 downwards and closes the claw 21. At the same time, the cylinder presses down on the sliding piece 125 until the pressure plate presses down on the switch body 123. At 23:00, it indicates that the lock is in place. At this time, the drive connector 222 engages in the slot 213 to lock the claw 21. When unlocking the cylinder, the drive connector 222 moves out of the slot 213, releasing the lock on the claw 21. The cylinder is then removed upwards, and the slide 125 moves upwards to reset under the action of the return spring 126. The slide 125 is provided with a limiting groove 1251, and the guide box 124 is provided with a limiting block 1241. The limiting block 1241 slides in the limiting groove 1251, and the upper and lower sliding distance of the slide 125 is limited by the limiting block 1241 and the limiting groove 1251.
[0021] In practical use, the mechanism to be locked has a horizontal cylinder. When locking is required, the cylinder on the mechanism to be locked is aligned between the two sets of claws 21, and the claws 21 are struck downwards. The claws 21 rotate around the first rotating axis 14 and close, and the locking groove 212 clamps the cylinder. During the downward pressing of the cylinder, the slider 125 is pushed down along the slide groove of the guide box 124, and the return spring 126 is compressed. When the bottom plate of the slider 125 presses the switch body 123, it indicates that the locking is in place, and the switch body 123 sends a signal. After receiving the signal, the motor 31 starts and drives the unlocking block 311 to rotate, so that the pressing column 312 separates from the inclined protrusion 321. Under the action of the torsion spring, the hook 22 rotates around the second rotating axis 15, and the snap-fit connector 222 snaps into the snap-fit groove 213, locking the claw 21 and completing the locking.
[0022] When unlocking is required, after receiving the unlocking signal, the motor 31 starts and drives the unlocking block 311 to rotate, and the pressing column 312 presses the inclined protrusion 321 of the connecting arm 32; the connecting arm 32 rotates around the support 16, raising the opening 221 end of the hook 22, so that the locking head 222 moves out of the slot 213, and the locking of the claw 21 is released; the cylinder is taken out upward, and the slide 125 moves upward and resets under the elastic force of the reset spring 126. The claw 21 naturally opens after the cylinder is taken out, waiting for the next locking.
[0023] In summary, the locking mechanism has a horizontal cylinder, and two symmetrically arranged locking components 2 can simultaneously fix both sides of the mechanism to be fixed. The locking groove 212 fits tightly with the cylinder, and with the torsion spring and hook 22 locking structure, the locking is firm and has strong resistance to vibration and impact. The limiting plate 112 cooperates with the limiting protrusion 211 to prevent the claw 21 from rotating excessively, further improving the locking stability. During the locking process, the cylinder presses down on the sliding plate 125 to trigger the switch body 123, providing intuitive feedback on the locking status and avoiding insecure locking due to insufficient impact or positional deviation. The limiting structure of the sliding plate 125 ensures triggering accuracy, providing accurate signals for subsequent locking actions and improving the overall operational reliability of the mechanism. The motor 31 drives the unlocking block 311 to quickly rotate the hook 22 through the connecting arm 32, achieving unlocking with a fast response. The torsion spring provides a stable reset force for the hook 22, ensuring that the locking connector 222 quickly and accurately engages with the slot 213 after unlocking; the slider 125 achieves automatic reset through the reset spring 126, which has a simple structure and high reset accuracy.
