Abstract
Description
Technical Field
[0001] This utility model relates to the field of compression structures, and more particularly to a parachute belt compression structure. Background Technology
[0002] A parachute is a deployable aerodynamic decelerator that inflates and deploys relative to the air, utilizing the principle of air resistance. The parachute belt is a part of the parachute system, usually connected to the harness system, together forming the safety equipment worn by the skydiver. This belt is designed to secure the skydiver, ensuring that the skydiver's body remains stable during the jump, and can be connected to the parachute through the harness system. By tightening the belt, the skydiver can better control their body, avoiding unnecessary tumbling or spinning in the air, thus ensuring a safe landing.
[0003] Existing belts typically use adjustable buckles for tightening. During a skydive, these buckles may loosen due to factors such as vibration and wind pressure, resulting in unstable belt tension and affecting the skydiver's safety and stability. Furthermore, in actual skydiving situations, skydivers may find it difficult to quickly and accurately adjust the buckles to achieve the desired tightening effect.
[0004] Therefore, the existing parachute belts typically use adjustable buckles for tightening, which may loosen due to factors such as vibration and wind pressure, affecting the safety and stability of the parachutist. Furthermore, during actual parachuting, it may be difficult for the parachutist to achieve the ideal tightening effect. A parachute belt tightening structure can be designed to tighten the belt by utilizing the distance between the rotating shaft and the spring eccentricity and the spring's compression force. Utility Model Content

[0007] Preferably, the snap-fit plate is first snapped into the clamping housing, then the Milanese steel strap is wrapped around the jumper's waist and passed through the clamping housing, and then the Milanese steel strap is clamped by the rotating shaft and spring on the clamping housing.
[0008] Preferably, a snap-fit block is fixedly installed on the snap-fit plate near the side of the clamping housing.
[0009] Preferably, the clamping housing has two sets of vertically inserted connecting shafts arranged laterally on the side near the snap-fit plate.
[0010] Preferably, a limiting plate is fitted around the connecting shaft.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] See also Figures 1-4 This utility model provides an embodiment: a parachute waist belt clamping structure, including a snap-fit plate 1, a clamping housing 2, and a Milanese steel belt 3; the snap-fit plate 1 has a clamping housing 2 on one side for clamping the Milanese steel belt 3, the clamping housing 2 has a Milanese steel belt 3 for fixing the parachutist passing through the middle of the clamping housing 2, a rotating shaft 204 is transversely passing through the side of the clamping housing 2 away from the snap-fit plate 1, a spring 206 is sleeved on the outside of the rotating shaft 204, a pressure plate 205 is sleeved on the outside of the spring 206 and movably connected to the rotating shaft 204, and a spring rubber damper is provided inside the spring 206.
[0022] See also Figures 2-3 In this embodiment, a snap-fit block 101 is fixedly installed on the snap-fit plate 1 near the clamping housing 2. The snap-fit block 101 can drive the snap-fit plate 1 to quickly connect with the clamping housing 2. Two sets of vertically inserted connecting shafts 201 are arranged horizontally on the side of the clamping housing 2 near the snap-fit plate 1. The limiting plate 202 is movably connected to the clamping housing 2 through the connecting shafts 201 to facilitate the connection of the snap-fit plate 1. The limiting plate 202 is sleeved on the outside of the connecting shafts 201. The limiting plate 202 can quickly connect the snap-fit block 101 by rotating and rebounding. The connecting shaft 201 is movably connected to the pressing housing 2. The locking block 101 abuts against the limiting plate 202, causing it to rotate outward through the connecting shaft 201. When it encounters the groove on the locking block 101, it springs back to complete the locking. The pressing housing 2 has two sets of connecting shafts 201 with a locking groove 203 between them. The locking block 101 drives the locking plate 1 to be positioned and locked with the pressing housing 2 through the locking groove 203. First, the locking plate 1 is picked up, and then the locking block 101 drives the locking plate 1 to be positioned and locked with the pressing housing 2 through the locking groove 203.
[0023] See also Figure 4 In this embodiment, a rectangular slot 207 is provided in the middle of the clamping housing 2, located below the snap-fit groove 203. Pick up the Milan steel strap 3, wrap it around the parachutist's waist, and pass it through the clamping housing 2 along the rectangular slot 207.
[0024] During operation, first pick up the snap-fit plate 1, then the snap-fit block 101 drives the snap-fit plate 1 to be positioned and snapped into the clamping housing 2 through the snap-fit groove 203. During this process, the snap-fit block 101 abuts against the limiting plate 202, causing it to rotate outward through the connecting shaft 201. When it encounters the groove on the snap-fit block 101, it springs back to complete the snap-fit. Then pick up the Milan steel strap 3, wrap it around the parachutist's waist, and pass it through the clamping housing 2 along the rectangular slot 207. Adjust it according to the parachutist's own situation. After confirming that everything is correct, press the pressure plate 205 to make it rotate downward along the rotating shaft 204. At the same time, the Milan steel strap 3 is clamped by using the eccentric distance between the rotating shaft 204 and the spring 206 and the compression force of the spring 206.
[0025] Through the above steps, the snap-fit plate 1 is first snapped together with the clamping housing 2. Then, the Milanese steel belt 3 is wrapped around the jumper's waist and passed through the clamping housing 2. The Milanese steel belt 3 is then clamped by the rotating shaft 204 and the spring 206 on the clamping housing 2. This method provides continuous clamping force, ensuring that the belt remains tightly fitted in various jumping postures, thereby increasing the jumper's stability and safety. It also allows for easy adjustment of the belt's clamping degree to suit the body shape and comfort needs of different jumpers. This addresses the problem that existing belts, which typically use adjustable buckles for clamping, may loosen due to vibration, wind pressure, or other factors, affecting the jumper's safety and stability. Furthermore, it is difficult for jumpers to achieve the ideal clamping effect during actual jumps.
