A detachable connection split type protective clothing and a connection method thereof

Abstract

This invention relates to the technical field of protective clothing, specifically a two-piece protective suit with a snap-lock connection and its connection method. The suit includes a main body and shoulder straps at both ends. Buckles are provided on the shoulder straps, and a locking tongue and a locking groove are provided on one side of each buckle. This invention achieves an anti-reverse loosening effect by automatically locking upon insertion through the interlocking design of the locking tongue, lifting platform, and rotating arm in the self-tightening buckle, effectively solving the problem of loosening caused by external vibration. Simultaneously, the lateral unlocking mechanism, which uses a toggle plate to control the rotating arm's reset, avoids the accidental activation defects of traditional direct-pressure unlocking, resulting in higher operational reliability. Furthermore, the lifting platform's pop-out reset function integrated inside the lock seat actively pushes the locking tongue outwards upon unlocking, achieving rapid tongue separation and improving emergency disassembly efficiency.

Description

Technical Field

[0001] This invention relates to the technical field of protective clothing, specifically a two-piece protective suit with a snap-on connection and its connection method. Background Technology

[0002] As an important type of protective gear, split-type protective clothing is widely used in various scenarios such as industrial operations, emergency rescue, military services, and outdoor high-risk environments. This type of split-type protective clothing adopts a structure that only covers the upper part of the wearer's torso, and is mainly composed of an upper protective body. Unlike traditional one-piece or two-piece protective clothing, it improves the flexibility of wearing and the convenience of operation while ensuring the protection function of the core torso area.

[0003] In terms of the wearing and fixing method, the protective suit is equipped with flexible shoulder straps on both sides of the shoulders. The shoulder straps extend upward from the front chest area and extend from the shoulders to the back, forming a wrap around the shoulders of the human body through the two shoulder straps, thereby stably fixing the upper protective body to the wearer's torso. In order to meet the functional requirements of quick dressing and emergency removal, the protective suit is equipped with a release connection structure in the area above the shoulder straps.

[0004] In the release structure of this type of split protective clothing, a combination of double shoulder straps and release connection structure is usually adopted. The shoulder straps are closed by inserting the male buckle latch of the buckle into the female buckle seat, so that the upper protective body can be fixed to the wearer's torso. In this type of conventional buckle structure, the male and female buckles mainly rely on the one-way engagement of elastic claws or similar elastic elements in the locking position to maintain the connection. The locking force is highly dependent on the material rebound performance of the elastic element itself.

[0005] In actual operation, under complex application scenarios with high intensity and high dynamics, the static locking structure of conventional buckles is prone to hidden loosening under continuous vibration and impact, posing a risk of connection failure; its exposed unlocking button is easily triggered accidentally during violent activities, affecting the reliability of protection; at the same time, the two-step operation of precise pressing and manual separation required for emergency removal can be delayed and stuck. Summary of the Invention

[0006] The purpose of this invention is to provide a snap-on type protective suit and its connection method to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A two-piece protective suit with a snap-lock connection includes a suit body and shoulder straps at both ends of the suit body. Each shoulder strap has a buckle, a latch, and a locking groove on one side of the latch. Each end of the suit body has a lock seat and a slot on top of the lock seat. The latch engages with the lock seat. The lock seat contains a rotating shaft and a rotating arm rotatably mounted on the rotating shaft. Each end of the rotating arm has a limit mechanism and a spring-loaded engagement mechanism. The lock seat contains a positioning mechanism that engages with the spring-loaded engagement mechanism. The lock seat also contains a lifting assembly that engages with the rotating arm through a pressing mechanism. One end of the rotating arm has a toggle mechanism that slides on the lock seat.

[0009] A split-type protective suit with a release connection as described above: the limiting mechanism includes a convex limiting block disposed on one side of the top of the rotating arm, and the rotating arm abuts against the locking groove on one side of the locking tongue through the convex limiting block.

[0010] A split-type protective suit with a release connection as described above: the elastic snap-fit ​​mechanism includes a sliding frame slidably mounted on the bottom end of the rotating arm, a large spring is provided between the sliding frame and the rotating arm, and an arc-shaped component is provided at one end of the sliding frame.

[0011] As described above, a split-type protective suit with a release connection: the positioning mechanism includes a limiting seat disposed inside the lock seat and a semi-circular limiting protrusion disposed in the middle of the limiting seat, and positioning grooves are provided at both ends of the limiting seat.

[0012] As described above, a split-type protective suit with a snap-lock connection: the arc-shaped component and the semi-circular limiting protrusion on the limiting seat are press-fitted together, and the positioning grooves at both ends of the limiting seat are fitted into the arc-shaped component.

[0013] As described above, a split-type protective suit with a release connection includes a lifting assembly comprising a limiting cylinder disposed inside the locking seat and a limiting slide mounted on the limiting cylinder, wherein a first small spring is provided between the limiting cylinder and the limiting slide.

[0014] As described above, a split-type protective suit with a release connection has a lifting platform on the top of the limiting slide and an abutment plate slidably installed at one end of the lifting platform, with a second small spring between the lifting platform and the abutment plate.

[0015] As described above, a split-type protective suit with a release connection has a cavity at one end of the rotating arm, and the cavity abuts against the abutment plate.

[0016] As described above, a split-type protective suit with a release connection includes a toggle mechanism comprising a positioning cylinder disposed at one end of the rotating arm and an arc-shaped limiting frame disposed on the positioning cylinder. The arc-shaped limiting frame is connected to the inner side of the lock seat, and a toggle plate is slidably connected to one end of the positioning cylinder.

[0017] The connection method for a split-type protective suit using the release connection method described above includes the following steps:

[0018] Step 1: First, insert the latch at the bottom of the shoulder strap into the slot at the top of the lock seat. The front end of the latch will first contact and press down on the built-in lifting platform. As the lifting platform descends, it presses the inside of the rotating arm through the abutment plate, causing the rotating arm to rotate around the rotation axis.

[0019] Step 2: After deflection, the convex limiting block on the rotating arm engages in the preset slot on the locking tongue for locking, and the arc-shaped part at the bottom is moved to the positioning groove at the other end for limiting.

[0020] Step 3: When unlocking is required, move the toggle plate on one side of the lock body. The positioning cylinder of the toggle plate slides, and at the same time, it drives the rotating arm to deflect in the opposite direction and reset, thus releasing the locking constraint on the lock tongue.

[0021] Step 4: Then, the lifting platform pops up under the action of the first small spring at its bottom, simultaneously driving the lock tongue to automatically retract from the lock seat body, completing the unlocking process.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] Through the interlocking design of the self-tightening latch, the locking tongue, the lifting platform, and the rotating arm, an anti-reverse loosening effect is achieved by automatically locking upon insertion, effectively solving the problem of loosening caused by external vibration. At the same time, the lateral unlocking mechanism that uses a toggle plate to control the rotation arm reset avoids the defect of easy accidental activation in traditional direct-pressure unlocking, resulting in higher operational reliability. In addition, the lifting platform pop-out reset function integrated inside the lock seat can actively push the locking tongue outward at the moment of unlocking, realizing rapid separation of the locking tongue and improving emergency release efficiency.

[0024] This invention achieves an active self-tightening function that "locks firmly upon insertion," effectively preventing the latch from accidentally loosening and rebounding under violent movement or continuous vibration. At the same time, it achieves a quick, effortless, and intuitive one-button separation effect, improving the wearer's removal efficiency in emergency situations. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] Please see Figures 1-10As an embodiment of the present invention, the snap-on type protective suit includes a protective suit body 1, shoulder straps 2 disposed at both ends of the protective suit body 1, buckles 3 disposed on the shoulder straps 2, a locking tongue 4 and a locking groove 5 disposed on one side of the buckle 3, a locking seat 6 and a slot 7 disposed on the top of the locking seat 6 disposed at both ends of the protective suit body 1, the locking tongue 4 and the locking seat 6 being plugged into each other, the locking seat 6 being provided with a rotating shaft 8 and a rotating arm 9 rotatably mounted on the rotating shaft 8, the two ends of the rotating arm 9 being respectively provided with a limit mechanism and an elastic locking mechanism, the locking seat 6 being provided with a positioning mechanism that cooperates with the elastic locking mechanism, the locking seat 6 being provided with a lifting assembly that cooperates with the rotating arm 9 by compression, and a toggle mechanism disposed at one end of the rotating arm 9, the toggle mechanism being slidably disposed on the locking seat 6.

[0038] In this embodiment, the locking tongue 4 at the bottom of the shoulder strap 2 is first inserted into the slot 7 at the top of the lock seat 6. The front end of the locking tongue 4 first contacts and presses down on the built-in lifting component. During the downward movement, the lifting component drives the rotating arm 9 to deflect through linkage. After deflection, the limiting mechanism on the rotating arm 9 is engaged in the preset slot 7 on the locking tongue 4, thereby locking the locking tongue 4 and preventing it from being pulled out in the opposite direction. When unlocking is required, the toggle mechanism on one side of the lock seat 6 body is activated. The toggle mechanism drives the rotating arm 9 to deflect in the opposite direction and reset, releasing the locking constraint on the locking tongue 4. At this time, the lifting component pops up under the action of its bottom reset elastic element, and simultaneously drives the locking tongue 4 to automatically exit the lock seat 6 body, completing the unlocking process.

[0039] As a further embodiment of the present invention, the limiting mechanism includes a convex limiting block 10 disposed on one side of the top of the rotating arm 9, and the rotating arm 9 abuts against the locking groove 5 on one side of the locking tongue 4 through the convex limiting block 10.

[0040] In this embodiment, the convex limiting block 10 is disposed on one side of the top of the rotating arm 9, and can be engaged with the locking groove 5 on one side of the locking tongue 4.

[0041] As a further embodiment of the present invention, the elastic locking mechanism includes a sliding frame 12 slidably mounted on the bottom end of the rotating arm 9, a large spring 13 is provided between the sliding frame 12 and the rotating arm 9, and an arc-shaped component 14 is provided at one end of the sliding frame 12.

[0042] In this embodiment, the sliding frame 12 is slidably disposed at the bottom end of the rotating arm 9, and a large spring 13 is disposed between the sliding frame 12 and the rotating arm 9. The spring can provide a large elastic force, and the arc-shaped member 14 is disposed at the bottom end of the sliding frame 12.

[0043] As a further embodiment of the present invention, the positioning mechanism includes a limiting seat 15 disposed inside the lock seat 6 and a semi-circular limiting protrusion 16 disposed in the middle of the limiting seat 15, and positioning grooves 17 are provided at both ends of the limiting seat 15.

[0044] In this embodiment, a semi-circular limiting protrusion 16 is provided in the middle of the limiting seat 15, and positioning grooves 17 are reserved at both ends to accommodate the arc-shaped part 14, so that the arc-shaped part 14 will only stay inside the two positioning grooves 17.

[0045] As a further embodiment of the present invention, the arc-shaped component 14 is press-fitted with the semi-circular limiting protrusion 16 on the limiting seat 15, and the positioning grooves 17 opened at both ends of the limiting seat 15 are fitted with the arc-shaped component 14.

[0046] In this embodiment, when the rotating arm 9 rotates around the rotating axis 8, the arc-shaped part 14 at the bottom will press against the semi-circular limiting protrusion 16, causing the arc-shaped part 14 to drive the sliding frame 12 to slide upward and compress the large spring 13. Then the arc-shaped part 14 will pass over the semi-circular limiting protrusion 16 and be inserted into the positioning groove 17 at the other end.

[0047] As a further embodiment of the present invention, the lifting assembly includes a limiting cylinder 18 disposed inside the locking seat 6 and a limiting slide 20 slidably mounted on the limiting cylinder 18, wherein a first small spring 19 is disposed between the limiting cylinder 18 and the limiting slide 20.

[0048] In this embodiment, a limiting slide block 20 is slidably installed inside the limiting cylinder 18, and a first small spring 19 is provided inside the limiting cylinder 18 for elastically limiting the limiting slide block 20.

[0049] As a further embodiment of the present invention, the top of the limiting slide 20 is provided with a lifting platform 21 and an abutment plate 22 slidably installed at one end of the lifting platform 21, and a second small spring 23 is provided between the lifting platform 21 and the abutment plate 22.

[0050] In this embodiment, the lifting platform 21 is located on top of the limiting slide 20, and the lifting platform 21 is in a pressing fit with the locking tongue 4 above it. One end of the lifting platform 21 is slidably installed with the abutment plate 22.

[0051] As a further embodiment of the present invention, a cavity 11 is provided at one end of the rotating arm 9, and the cavity 11 abuts against the abutting plate 22.

[0052] In this embodiment, the abutment plate 22 extends onto the cavity 11 at one end of the rotating arm 9.

[0053] As a further embodiment of the present invention, the actuating mechanism includes a positioning cylinder 24 disposed at one end of the rotating arm 9 and an arc-shaped limiting frame 25 disposed on the positioning cylinder 24. The arc-shaped limiting frame 25 is connected to the inner side of the lock seat 6, and an actuating plate 26 is slidably connected to one end of the positioning cylinder 24.

[0054] In this embodiment, the positioning cylinder 24 moves with the rotating arm 9, and the arc-shaped limiting frame 25 limits the sliding direction of the positioning cylinder 24. The positioning cylinder 24 and the actuating plate 26 are installed in an up-and-down sliding manner. When the actuating plate 26 is pushed, the positioning cylinder 24 will slide along the trajectory of the arc-shaped limiting frame 25, and at the same time, it will slide in cooperation with one end of the actuating plate 26.

[0055] The elastic force of the large spring 13 is greater than that of the first small spring 19 and the second small spring 23.

[0056] The connection method for a split-type protective suit using the release connection method described above includes the following steps:

[0057] Step 1: First, insert the locking tongue 4 at the bottom of the shoulder strap 2 into the slot 7 at the top of the lock seat 6. The front end of the locking tongue 4 first contacts and presses down on the built-in lifting platform 21. During the downward movement, the lifting platform 21 presses the inner side of the rotating arm 9 through the abutment plate 22, causing the rotating arm 9 to rotate around the rotating axis 8.

[0058] Step 2: After deflection, the convex limiting block 10 on the rotating arm 9 is locked into the preset slot 7 on the locking tongue 4, and the arc-shaped part 14 at the bottom is moved to the positioning groove 17 at the other end for limiting.

[0059] Step 3: When unlocking is required, move the toggle plate 26 on one side of the lock seat 6 body. The positioning cylinder 24 of the toggle plate 26 slides, and at the same time drives the rotating arm 9 to deflect in the opposite direction and reset, thereby releasing the locking constraint on the lock tongue 4.

[0060] Step 4: Subsequently, the lifting platform 21 pops up under the action of the first small spring 19 at its bottom, which simultaneously drives the locking tongue 4 to automatically exit the locking seat 6 body, completing the unlocking process.

[0061] The above embodiments are exemplary and not restrictive. Therefore, any technical solutions that can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention are included within the scope of the present invention.
