Description

Technical Field

[0001] This utility model belongs to the field of lock picking, specifically relating to a tool for disassembling the connecting shaft of a life-saving parachute. Background Technology

[0002] In the maintenance of life-saving parachutes, disassembling the locking plate connecting shaft of the parachute control strap is a crucial step to ensure proper equipment maintenance. Traditional disassembly methods rely on two people working together: each holds a flathead screwdriver and simultaneously applies force to the slots on both sides of the locking plate to separate the bolts. This operating mode has long been a common practice in the industry, but in practical application, it has gradually revealed numerous problems.

[0003] One of the core challenges of traditional disassembly methods is the high operational resistance and difficulty in control. Because the bolts of the life-saving parachute control belt with locking plates need to be reinforced with fastening adhesive during installation to ensure stability during use, the friction between the flathead screwdriver and the bolt slot increases significantly during subsequent disassembly. Operators need to apply considerable force to drive the bolts to rotate, which is not only laborious but also makes it difficult to accurately control the operating rhythm.

[0004] More importantly, traditional methods suffer from serious safety hazards and inefficiencies. During operation, the fit between the flathead screwdriver and the slotted bolt is unstable, making it prone to accidental detachment due to uneven force or angular deviation, potentially causing cuts or other injuries to the operator. Furthermore, the cumbersome process requiring two people typically takes 10-20 seconds for a single disassembly, reducing overall maintenance efficiency and making it unsuitable for rapid operations in confined spaces and other complex environments. Utility Model Content

[0005] The purpose of this utility model is to address the problems of complex operation, low efficiency, and insufficient safety in the existing disassembly methods of the control belt locking plate connecting shaft of a life-saving parachute, and to provide a life-saving parachute connecting shaft disassembly tool with the characteristics of simple structure, convenient operation, and high reliability, so as to enable a single person to complete the disassembly operation efficiently and safely in a narrow space.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: a tool for disassembling a life-saving parachute connecting shaft, comprising a grip base, a first pillar and a second pillar symmetrically mounted on the upper part of the grip base, a first limiting post mounted on the side of the first pillar facing the second pillar, a first sliding groove provided on the side of the first limiting post facing the second pillar, an upper positioning strip vertically arranged in the middle of the first sliding groove, a first mounting hole opened at the bottom of the first sliding groove, and a clamping mechanism provided in the first mounting hole; a second limiting post mounted on the side of the second pillar facing the first pillar, a second sliding groove provided on the side of the second limiting post facing the first pillar, and a second mounting hole penetrating through the bottom of the second sliding groove; a third mounting hole penetrating through the bottom of the second pillar, and a movable rod jointly mounted in the second mounting hole and the third mounting hole; a positioning part provided after one end of the movable rod extends out of the second mounting hole, and the positioning part is arranged opposite to the clamping mechanism; an operating part provided after the other end of the movable rod extends out of the third mounting hole. When using this invention to disassemble the locking plate of the parachute control strap, the two ends of the connecting shaft of the parachute control strap locking plate can be inserted into the corresponding first and second sliding grooves respectively. Then, the movable rod can be rotated to align the positioning part of the movable rod with the slot of the bolt on the connecting shaft of the parachute control strap locking plate. Then, the corresponding spiral can be removed by rotating the movable rod, thereby easily disassembling the locking plate of the parachute control strap.

[0007] Furthermore, the clamping mechanism includes a first compression spring and a clamping block arranged sequentially in the first mounting hole along the direction close to the second support. A lower positioning strip is provided on the side of the clamping block facing the second support. The lower positioning strip can be aligned with the upper positioning strip, and the lower positioning strip can ensure that the clamping block can be engaged with the slot at the end of the connecting shaft of the life-saving parachute control belt with the locking plate.

[0008] Furthermore, the positioning part includes a second positioning strip, which is disposed on the end of the movable rod facing the first support, and can ensure that the end of the movable rod can be engaged with the slot of the bolt of the connecting shaft of the parachute control belt with locking plate.

[0009] Furthermore, the wall of the third mounting hole is provided with a third stepped surface, a shoulder is provided on the movable rod at the position inside the second mounting hole, and a second compression spring is sleeved on the movable rod at the position inside the third mounting hole. The two ends of the second compression spring abut against the shoulder and the third stepped surface respectively, thereby ensuring that the movable rod can always be in close contact with the bolt.

[0010] Furthermore, the wall of the second mounting hole is provided with a second stepped surface, and the shoulder can abut against the second stepped surface, thereby constraining the range of motion of the movable rod.

[0011] Furthermore, the operating part of the movable lever is equipped with a handle, which facilitates operation by the operator.

[0012] Furthermore, the grip base features gripping auxiliary grooves on its sides, and this design creates a C-shaped structure, effectively preventing slippage during gripping. It also significantly improves the fit between the grip base and the hand, maintaining a reliable grip, especially in humid environments or when hands are sweaty, reducing the risk of items accidentally falling.

[0013] Furthermore, a second discharge port is provided on the upper part of the grip, which is opposite to and connected to the first discharge port described below, so as to ensure that the disassembled bolts can be discharged smoothly.

[0014] Furthermore, both the first and second pillars are L-shaped. The vertical parts of the first and second pillars are located at the top. The first limiting post is installed on the vertical part of the first pillar, and the second limiting post is installed on the vertical part of the second pillar. The horizontal parts of the first and second pillars are located at the bottom. The horizontal parts of the first and second pillars are arranged opposite to each other, and the horizontal part of the second pillar is provided with a discharge port, through which the disassembled bolts can be discharged.

[0015] Furthermore, a support is installed at the bottom of the grip, allowing it to be placed on the support.

[0016] As can be seen from the above technical solution, this utility model has the following advantages: The parachute connecting shaft disassembly tool, through its targeted structural design, exhibits multiple beneficial effects in terms of ease of operation, stability, and smooth operation. Specifically, regarding ease of operation, on the one hand, the tool's symmetrical design of the first and second sliding grooves allows for quick locking and positioning of both ends of the connecting shaft without complex alignment adjustments; on the other hand, the operating part at the end of the movable rod is equipped with a handle, and with the precise fit between the positioning part and the bolt slot, bolt disassembly can be completed in just two steps: "locking in" and "rotating," significantly reducing the operational threshold and improving the efficiency of the entire disassembly operation, requiring only 2-3 seconds; simultaneously, because it can be operated by a single person, it is also suitable for operation in confined spaces.
