Abstract
Description
Technical Field
[0001] This utility model relates to the field of quick-release lock technology, specifically to a sealed quick-release lock. Background Technology
[0002] Quick-release locks are locking devices that allow for rapid connection and disconnection, widely used in applications requiring frequent disassembly and assembly. They are designed to provide a fast and easy operating experience while ensuring safety and reliability. On aircraft, quick-release locks are widely used on various doors and covers to ensure quick and reliable locking and unlocking. However, moisture in the air or rainwater can seep into the quick-release lock. This rainwater can cause rust and corrosion of metal components, especially in high humidity or salt spray environments. Rust and corrosion reduce the mechanical performance of the quick-release lock, potentially leading to jamming, difficulty in operation, or malfunction. Furthermore, moisture or rainwater carries dust, which can also be introduced into the quick-release lock. This dust increases wear and tear, reducing its lifespan and reliability. Utility Model Content
[0003] The present invention aims to provide a sealed quick-release lock to solve the problem that rainwater ingress affects the performance of current quick-release locks.
[0004] To solve the above technical problems, this utility model provides the following technical solution: a sealed quick-release lock, including a lock base and a lock buckle, the lock buckle including a cylindrical sleeve, a coaxial pin hole at the central axis of the sleeve, the pin hole penetrating from the top of the sleeve to the bottom of the sleeve, a vertically positioned spring installed in the pin hole, a locking pin provided in the spring, the bottom end of the locking pin extending downward beyond the bottom end of the sleeve, horizontally arranged latching pins fixedly connected to both opposite sides of the locking pin, the latching pins being located below the sleeve, the top end of the locking pin extending upward beyond the top of the sleeve and fixedly connected to a locking pin head, the locking pin head being used to drive the locking pin to rotate;
[0005] The lock base includes a base and a sealing cover. The base has a core hole for inserting a sheath. The bottom of the base has an clearance hole, the shape of which is the same as the shape of the lock pin and the two locking pins combined. The base has two spiral grooves on opposite sides for the locking pins to rotate along their spiral surfaces at a rotation angle of 90°. The upper ends of the base are fixedly connected to two support plates. The sealing cover is connected to the support plates and seals the base.
[0006] Furthermore, each of the trays is provided with mounting holes, which are used to fix the trays to the mounting location by screws. The walls of the mounting holes extend downwards, and a bracket is fixedly connected to the sealing cover, and the bracket is fixedly connected to the tray.
[0007] Furthermore, the upper part of the sealing cover is tubular, and the bottom of the sealing cover is hemispherical.
[0008] Furthermore, the base is provided with two grooves, which are located at the bottom ends of the two spiral grooves respectively.
[0009] Furthermore, the locking pin head is provided with a slot.
[0010] Furthermore, the locking pin head is provided with a cross groove.
[0011] Furthermore, a butterfly head is fixedly connected to the locking pin head, which is used to be held and rotated by fingers, thereby causing the locking pin head to rotate.
[0012] The beneficial effects of this utility model are:
[0013] 1. This solution uses a sealing cover to enclose and seal the base to prevent rainwater from entering the base. At the same time, after the latch is locked onto the base, the locking pin head can block the opening of the core hole of the base to prevent rainwater from entering through the opening of the core hole, thereby preventing rainwater from entering the quick-release lock.
[0014] 2. This solution uses a sealing cover and a locking buckle to form a sealed quick-release lock, which prevents moisture and rainwater from entering, thereby preventing the inside of the quick-release lock from rusting. This ensures the mechanical performance of the quick-release lock while also extending its service life. Attached Figure Description
[0015] Figure 1 This is a structural schematic diagram of a sealed quick-release lock according to the present invention. Detailed Implementation
[0016] The following detailed description illustrates the specific implementation method:
[0017] The reference numerals in the accompanying drawings include: 1. Locking pin head; 2. Spring; 3. Locking pin; 4. Protective sleeve; 5. Clip; 6. Support plate; 7. Mounting hole; 8. Bracket; 9. Sealing cover; 10. Base; 11. Groove; 12. Spiral groove.
[0018] The basic implementation examples are as follows: Figure 1 As shown:
[0019] A sealed quick-release lock includes a lock base and a lock buckle. The lock buckle includes a cylindrical sleeve 4. A coaxial pin hole is provided at the central axis of the sleeve 4. The pin hole extends from the top of the sleeve 4 to the bottom of the sleeve 4. A vertically positioned spring 2 is installed in the pin hole. A locking pin 3 is provided in the spring 2. The bottom end of the locking pin 3 extends downward beyond the bottom end of the sleeve 4. Horizontally arranged latches 5 are fixedly connected to both opposite sides of the locking pin 3. The latches 5 are located below the sleeve 4. The top end of the locking pin 3 extends upward beyond the top of the sleeve 4 and is fixedly connected to a locking pin head 1. The surface of the locking pin head 1 is provided with one of the following: a slotted groove, a cross slot, and a butterfly head.
[0020] The lock base includes a base 10 and a sealing cover 9. The base 10 has a core hole for inserting the sheath 4. A clearance hole is located at the center of the bottom of the base 10, the shape of which is identical to the shape of the locking pin 3 and the two locking pins 5 combined. Two spiral grooves 12 are provided on opposite sides of the base 10, allowing the locking pins 5 to rotate along their spiral surfaces until they reach the bottom of the base 10, with a rotation angle of 90°. Two recesses 11 are located at the bottom ends of the two spiral grooves 12. A support plate 6 is located at the top of the base 10. A receiving hole is provided at the center of the plate 6, and the base 10 is fixed in the receiving hole. The upper surface of the base 10 and the upper surface of the support plate 6 are on the same plane. The support plate 6 is provided with two mounting holes 7, which are located on both sides of the base 10. The hole wall of the mounting hole 7 extends downward out of the lower surface of the support plate 6. A bracket 8 is fixedly connected to the upper part of the outer wall of the base 10. The bracket 8 is fixedly connected to the lower surface of the support plate 6. A bracket 8 is fixedly connected to the sealing cover 9. The bracket 8 is fixedly connected to the lower surface of the support plate 6. The upper part of the sealing cover 9 is tubular, and the bottom of the sealing cover 9 is a blind end with a hemispherical shape.
[0021] The specific implementation process is as follows:
[0022] Taking a quick-release lock with a slotted groove as an example, when locking, insert the latch into the core hole of the base 10, insert a flathead screwdriver into the slot, and then push the lock pin head 1 into the base 10. The lock pin head 1 is forced to push the lock pin 3 to move within the sleeve 4. At this time, the spring 2 is compressed by the lock pin head 1. At the same time, the bottom end of the pin shaft and the horizontally arranged locking pin 5 pass through the clearance hole and rotate the lock pin head 190°. When the lock pin head 1 rotates, it drives the two locking pins 5 to rotate through the lock pin 3. When the locking pins 5 rotate, they move along the guide of the spiral groove 12 until they move to the bottom end of the base 10 and then lock into the groove 11 to complete the locking. When unlocking, push the lock pin 1 into the base 10. The lock pin 1, through the lock pin 3, pushes the locking pin 5 out of the groove 11. Then, rotate the lock pin 1 ninety degrees in the opposite direction. At the same time as the lock pin 1 rotates in the opposite direction, the spring force of the spring 2 pushes the lock pin 1 upward until the locking pin 5 and the lock pin 3 return to their original positions, completing the unlocking. The sealing cover 9 wraps and seals the base 10 to prevent rainwater from entering the base 10. At the same time, after the latch is locked on the base 10, the lock pin 1 can seal the opening of the core hole of the base 10 to prevent rainwater from entering through the core hole opening.
