Description

Technical Field

[0001] This invention specifically relates to an abdominal quick release mechanism and an abdominal carrying strap. Background Technology

[0002] Currently, the personalized harness harness uses quick-release locks on both sides of the waist and an abdominal negative overload device. The quick-release locks on both sides of the waist are used to secure the pilot to the seat, while the abdominal negative overload device is used to secure the pilot to the seat from the abdomen. Connecting these harnesses is complex and involves multiple steps when the pilot removes them, thus reducing safety. Putting on the harnesses requires connecting the quick-release locks on both sides of the waist separately, which is also complex and increases the time required for onboard donning. Summary of the Invention

[0003] The purpose of this invention is to provide an abdominal quick release mechanism and abdominal carrying strap equipment, which can achieve quick release and quick installation, while being easy to operate and highly safe.

[0004] The technical solution adopted in this invention is:

[0005] A quick-release mechanism for the abdomen includes a lock body, a insert, and a locking tooth washer, locking teeth, locking tooth springs, a button cap, a flip cover, and a button cap spring disposed on the lock body. The flip cover is rotatably connected to the lock body and is arranged on one side of the button cap. One end of the flip cover is fastened to the button cap. The two ends of the button cap spring are respectively connected to the button cap and the lock body. The button cap spring is used to press the button cap with spring force to prevent the button cap and the flip cover from separating. The locking tooth washer is disposed below the other end of the flip cover. The locking teeth are connected to the lock body through the locking tooth springs. The upper end of the locking teeth protrudes from the locking tooth washer and is arranged at the insert of the lock body, corresponding to the lock hole on the insert after it is inserted into the lock body.

[0006] Preferably, the top of the locking tooth is provided with a beveled guide surface, which faces the insertion direction of the insert.

[0007] Preferably, the abdominal quick release mechanism further includes a base, a lock body is disposed on the base, and the base is used to connect with other equipment.

[0008] Preferably, the lock body is provided with a main lock cover, which is used to cover the lock tooth washer, lock tooth and lock tooth spring in the lock body.

[0009] Preferably, a locking pad is provided between the lock body and the main part of the lock cover.

[0010] Preferably, the main part of the lock cover is connected to the lock body by screws.

[0011] Preferably, the outer ring of the end of the flip cover that contacts the locking tooth washer has two arc-shaped segments with different radii in sequence, and the main body of the lock cover has a corresponding sliding groove that contacts the end of the flip cover. During the flip cover repositioning process, the sliding groove on the main body of the lock cover first contacts the large-radius arc-shaped segment of the flip cover, and then contacts the small-radius arc-shaped segment of the flip cover. The locking tooth washer is lifted back to its original position by the locking tooth spring, which drives the main body of the lock cover to reposition. In the first stage of the flip cover repositioning, the large-radius arc-shaped segment of the flip cover contacts the sliding groove on the main body of the lock cover, and the flip cover repositioning speed is relatively fast. In the second stage of the flip cover repositioning, the small-radius arc-shaped segment of the flip cover contacts the sliding groove on the main body of the lock cover, and the flip cover repositioning speed is slowed down to avoid the operator's hand being pinched.

[0012] Preferably, the insert slot is located on the side of the lock body.

[0013] Preferably, the flip cover is mounted on the lock body by a pin, and the flip cover can rotate around the pin.

[0014] Preferably, there are two locking teeth, symmetrically arranged on both sides of the flip cover, and two locking holes are provided on the locking tooth pads respectively, which are used for the two locking teeth to pass through.

[0015] The lock body has two insert slots on each side for inserting two inserts, which means two inserts are required.

[0016] An abdominal support harness includes an abdominal overload device and an abdominal quick release mechanism as described above, wherein the abdominal overload device is used to connect and secure a human body from the abdomen to a seat via the abdominal quick release mechanism.

[0017] The beneficial effects of this invention are:

[0018] In this invention, during the insertion of the insert into the lock body's insert slot, the locking teeth are first pressed down. When the insert's lock hole moves above the locking teeth, the spring force of the locking tooth spring causes the locking teeth to return to their original position and pass into the insert's lock hole, thus locking the lock body and the insert. Then, pressing down the button cap disengages it from the flip cover, and the flip cover flips outward. The flip cover rotates and presses down the locking tooth washer, causing the locking teeth to disengage from the insert's lock hole, thereby releasing the insert's lock and achieving quick release. This invention improves the overall operability of existing straps, providing quick release and quick installation. It is also convenient to operate and has high safety performance. The two-step unlocking method avoids accidental opening of the mechanism during use. Attached Figure Description

[0027] Example 1

[0028] A rapid abdominal release mechanism, such as Figures 1-4 As shown, the lock includes a lock body 1, a insert 2, and a locking tooth washer 4, a locking tooth 5, a locking tooth spring 6, a button cap 8, a flip cover 9, and a button cap spring 10, all mounted on the lock body 1. The flip cover 9 is rotatably connected to the lock body 1 and is positioned on one side of the button cap 8. One end of the flip cover 9 is fastened to the button cap 8. Both ends of the button cap spring 10 are connected to the button cap 8 and the lock body 1, respectively. The button cap spring 10 is used to press the button cap 8 with spring force to prevent the button cap 8 from disengaging from the flip cover 9. The locking tooth washer 4 is located below the other end of the flip cover 9. The locking tooth 5 is connected to the lock body 1 via the locking tooth spring 6. The upper end of the locking tooth 5 extends from the locking tooth washer 4. Plate 4 protrudes and is positioned at the insert slot of lock body 1, corresponding to the lock hole on plate 2 after it is inserted into lock body 1. During the insertion of the plate into the insert slot of lock body 1, the locking tooth 5 is first pressed down. When the lock hole of the plate moves above the locking tooth 5, the spring force of the locking tooth spring 6 causes the locking tooth to return to its original position and pass into the lock hole of the plate, thus locking the lock body and the plate. When the button cap 8 is pressed down, the button cap 8 is disengaged from the flip cover 9, and the flip cover 9 is flipped outward. The flip cover 9 rotates and presses down the locking tooth washer 4. The locking tooth washer 4 drives the locking tooth 5 to press down, causing the locking tooth 5 to disengage from the lock hole of the plate 2, thereby releasing the lock of the plate.

[0029] Example 2

[0030] It is basically the same as Example 1, but the locking teeth are limited based on Example 1, and the performance of Example 2 is better after the limitation.

[0031] The top of the locking tooth 5 is provided with a sloping guide surface, which faces the insertion direction of the insert 2. This allows the locking tooth 5 to be pressed down along the sloping guide surface and pass over the locking tooth 5 when the insert 2 is inserted from the insert opening of the lock body 1. After the locking hole on the insert 2 is located directly above the locking tooth 5, the locking tooth 5 is inserted into the locking hole on the insert 2 under the action of the locking tooth spring 6, thus forming a lock.

[0032] Furthermore, the abdominal quick release mechanism also includes a base 3, with a lock body disposed on the base, which is used to connect with other equipment.

[0033] Furthermore, the lock body 1 is provided with a lock cover main part 11, which is used to cover the lock tooth washer 4, the lock tooth 5 and the lock tooth spring 6 inside the lock body 1.

[0034] Furthermore, a locking washer 7 is provided between the lock body 1 and the main lock cover 11.

[0035] Furthermore, the main part 11 of the lock cover is connected to the lock body 1 by screws.

[0036] Furthermore, the outer ring of the end of the flip cover 9 that contacts the locking tooth washer is provided with two arc-shaped segments of different radii. The main body of the lock cover 11 is provided with corresponding sliding grooves that contact the end of the flip cover. During the return of the flip cover 9, the sliding groove on the main body of the lock cover 11 first contacts the large-radius arc-shaped segment of the flip cover 9, and then contacts the small-radius arc-shaped segment of the flip cover 9. The locking tooth washer 4 is lifted back to its original position by the locking tooth spring 6, which drives the main body of the lock cover 11 to return to its original position. During the first stage of the flip cover's return, the large-radius arc-shaped segment of the flip cover 9 contacts the sliding groove on the main body of the lock cover 11, and the flip cover 9 returns to its original position quickly. During the second stage of the flip cover's return, the small-radius arc-shaped segment of the flip cover 9 contacts the sliding groove on the main body of the lock cover 11, and the return speed of the flip cover 9 slows down to prevent the operator's hand from being pinched.

[0037] Composed of a lock body and two inserts, the inserts are released by pressing the button cap 8 and simultaneously flipping the cover 9. This structure is convenient to operate and highly secure. The cover 9 and the lock tooth washer 4 are precisely fitted together. The flipping process is divided into two stages, namely Level 1 and Level 2. Level 1 is from 0° to 40° and Level 2 is from 40° to 70°. The two-stage transition prevents the flipping from directly springing back and squeezing the operator's hand, thus improving structural safety.

[0038] Furthermore, the insert slot is located on the side of the lock body 1.

[0039] Furthermore, the flip cover 9 is mounted on the lock body via a pin 12, and the flip cover 9 can rotate around the pin 12.

[0040] Furthermore, there are two locking teeth 5, which are symmetrically arranged on both sides of the flip cover 9. The locking tooth pad 4 is provided with two locking holes, which are used for the two locking teeth 5 to pass through respectively.

[0041] The lock body 1 has two insert slots on each side for inserting two inserts 2, which means that two inserts 2 need to be configured accordingly.

[0042] Furthermore, the extension and retraction directions of the locking teeth 5 and the locking tooth spring 6 are perpendicular to the extension and retraction direction of the button cap spring 10, and the extension and retraction directions of the locking teeth 5 and the locking tooth spring 6 are perpendicular to the base of the lock body 1.

[0043] An abdominal support harness includes an abdominal overload device and an abdominal quick release mechanism as described above, wherein the abdominal overload device is used to connect and secure a human body from the abdomen to a seat via the abdominal quick release mechanism.

[0044] The working principle of this invention is as follows: When the insert 2 is inserted into the lock body 1, the inclined locking teeth 5 press the locking tooth spring 6 under the action of force; after the insert 2 is inserted into the lock body 1, the locking tooth spring 6 relaxes, thus fixing the insert 1. When the lock body 1 is released, by pressing the button cap 8, the button cap spring 10 is pressed down, and the constraint between the button cap 8 and the slider 9 disappears. By rotating the flip cover 9 to a certain angle, the flip cover 9 rotates around the pin 12 (fixed in the hole of the main part 11 of the lock cover), and at the same time presses the locking tooth washer 4. After being subjected to force, the locking tooth washer 4 transmits the force to the locking teeth 5 and the locking tooth spring 6 on both sides. At this time, the upper surface of the locking teeth 5 is flush with the upper surface of the locking tooth washer 4, and the insert 2 separates from the lock body 1.

[0045] In summary, this mechanism integrates the quick-release waist locks on both sides of the shoulder strap and the abdominal overload device into one unit, enabling rapid release through a two-step process. This invention improves the overall operability of existing shoulder straps, providing quick release and installation. It is also convenient to operate and offers high safety performance. The two-step unlocking method prevents the mechanism from opening due to accidental operation during use.
