Description

Technical Field

[0001] This utility model relates to a high-altitude work protection facility, and more particularly to a high-altitude work protective suit. Background Technology

[0002] High-altitude work protective clothing is a protective facility that provides all-round protection for workers when working at a height of 2 meters or more. The protective clothing is equipped with airbags, air cylinders, and fall protection sensors. When a worker accidentally falls during work, the fall protection sensors detect the fall and drive the air cylinder to inflate the airbags. The inflated airbags then wrap around the worker's body, thus cushioning the upward impact force generated by the collision with the ground or other objects during the fall and protecting the spine, back muscles, and other parts of the body from injury.

[0003] Based on this, existing high-altitude work protective suits are generally vest-style, with a full zipper and safety buckle on the front and buckle straps on both sides. When putting on the suit, the worker first closes the zipper, ensuring the suit completely wraps around their body. Then, the worker inserts the safety buckle, which provides secondary restraint to prevent the suit from shifting or falling off if the zipper comes undone during operation or a fall, thus ensuring the protective effect. The buckle straps on both sides are loose in the non-inflated state and provide lateral restraint, preventing the lower part of the suit from swaying left and right during operation. When the airbags are inflated, the buckle straps gradually straighten as the suit expands, restraining the airbags on the front and back, ensuring a tight fit and effective protection.

[0004] However, the above structure has certain drawbacks in actual use. Firstly, existing protective suits have two methods for installing safety buckles. The first method involves directly attaching the buckle to the suit via a ring-shaped strap. The advantage of this method is that the buckle is less prone to loosening, breaking, or shifting after being fastened. However, the drawback is that the lateral position of the buckle cannot be adjusted, resulting in the suit being either too loose or too tight after fastening, depending on the wearer's body shape, thus failing to achieve optimal protection. The second method involves adding a D-ring buckle in the middle of the strap for length adjustment, allowing workers to adjust the strap length to achieve the best fit and protection after wearing the suit. However, the drawback of this structure is that the D-ring buckle relies solely on friction with the strap for positioning. This leads to two problems: firstly, with prolonged use, the frictional resistance of the strap gradually decreases, causing the safety lock to shift and deviate during putting on, taking off, and pulling actions, affecting the tightening effect of the protective clothing; secondly, if the strap is pulled by external force during operation or a fall, it is also prone to lateral sliding, causing the safety lock to loosen directly, thus reducing the protective effect of the safety lock.

[0005] Secondly, existing protective suits, in order to allow for individual replacement of airbags, generally adopt a separate structure for use, combining the protective suit and airbags. Specifically, several pockets are cut into the inside of the protective suit to hold the airbags, and then the different parts of the airbags are placed into the pockets of the protective suit. When it is necessary to remove the airbags later, the workers can simply pull the airbags out of the pockets to separate them, making it convenient for workers to replace the airbags. Although this structure allows for individual replacement of airbags, there is no corresponding restraint mechanism after the airbags are inserted into the pockets. As a result, the flattened airbags are prone to wrinkling and shifting during use due to the twisting of the workers, which can obstruct the inflation of the airbags and prevent certain parts of the airbags from inflating in time, creating a safety hazard. On the other hand, if Velcro, snaps, or other fasteners are used to restrain the corners of the airbags, on the one hand, because these fasteners are all located on the inside of the protective vest, it will increase the difficulty for workers to flatten and secure the airbags; on the other hand, the airbags are also prone to dislodging under stress during subsequent use, and the fixation effect is not ideal.

[0006] Therefore, the existing installation methods for safety buckles and airbags in high-altitude work protective clothing have problems with poor installation stability and limiting effect. Utility Model Content

[0007] The purpose of this invention is to provide a protective suit for high-altitude operations. It can improve the installation stability and limiting effect of safety buckles and airbags.

[0008] The technical solution of this utility model is as follows: A protective suit for high-altitude operations includes a protective suit with a safety buckle in the middle. An airbag is detachably connected inside the protective suit, and a fall protection sensor and an air cylinder are connected to the outside of the protective suit. The protective suit includes a protective vest and an inner lining, which are nested and connected to each other. The airbag is detachably connected to the inside of the protective vest via the inner lining. The front of the protective vest forms a first opening, and the two sides of the protective vest are connected to each other via a first zipper. There are multiple safety buckles spaced at intervals at the first opening of the protective vest. The two ends of the safety buckles are connected to the two sides of the protective vest via straps, and a locking component is provided on one side of the strap. The locking component is used to fix the extension length of the strap through permanent deformation after pressing, so that the buckle's engagement position remains unchanged.

[0009] In the aforementioned high-altitude work protective clothing, the locking assembly includes a positioning component and a pressing component. The safety buckle is slidably connected to the buckle strap, the positioning component is fixedly connected to the buckle strap, the pressing component and the positioning component are distributed vertically, and the two ends of the pressing component and the positioning component are connected to each other through a deformation mechanism. A second opening is formed between the two deformation mechanisms for the buckle strap to pass through. The pressing component and the positioning component on the upper and lower sides of the second opening are provided with pressure teeth.

[0010] In the aforementioned high-altitude work protective clothing, the deformation mechanism includes a limiting piece disposed on the pressing part and a fastening groove disposed on the positioning part. The cross-sectional shape of the fastening groove is L-shaped. There are multiple limiting pieces that are spaced apart along the length direction of the strap. The lower end of the limiting piece extends to the bottom of the fastening groove and engages with the fastening groove.

[0011] In the aforementioned high-altitude work protective clothing, the positioning component and the pressing component are connected to each other by a flat-head screw. The nut of the flat-head screw is located on the side of the pressing component away from the positioning component, and the end of the flat-head screw passes through the positioning component and the buckle in sequence and is threaded to the positioning component.

[0012] In the aforementioned high-altitude work protective suit, the inner lining includes a front lining and a back lining, which are connected to each other via shoulder straps. Both the front and back linings have placement cavities on their inner sides for accommodating airbags, and several mounting openings are distributed around the placement cavities. The airbag includes a first airbag segment located outside the placement cavity, and multiple second airbag segments are connected around the first airbag segment. Each second airbag segment extends into a placement cavity. Several connecting pieces are distributed on both sides of the second airbag segments. The ends of the connecting pieces extend through the mounting openings to the outside of the inner lining and are detachably connected to a limiting component. The limiting component and the surface of the inner lining are connected to each other via a first snap fastener. The limiting component is used to limit the connecting pieces, preventing them from retracting into the placement cavity.

[0013] In the aforementioned high-altitude work protective suit, the connecting piece has a round hole in the middle, and the limiting component includes a split screw head and a nut. One end of the screw head is connected to a first snap, and the other end of the screw head passes through the round hole and is threaded to the nut. The outer diameter of the screw head is greater than the length of the installation opening.

[0014] In the aforementioned high-altitude work protective clothing, there are two front linings arranged side by side on the left and right sides of the protective vest, and one side of the front lining is connected to the protective vest via a second zipper; the top of the back lining is hung on the back of the protective vest via a hanging hook.

[0015] In the aforementioned high-altitude work protective clothing, the front liner and the back liner are connected to each other on both sides by snap fasteners; the top of both sides of the protective vest are provided with arm holes, and the lower end of the arm holes is provided with a covering layer. One end of the covering layer is fixedly connected to the protective vest, and the other end of the covering layer is connected to the protective vest via a second snap fastener.

[0016] In the aforementioned high-altitude work protective clothing, a third airbag is connected to the outside of the first airbag unit, and the top of the protective vest is provided with a neck pocket that matches the third airbag unit.

[0017] Compared with the prior art, this utility model has the following characteristics:

[0018] (1) This utility model, through the structural cooperation of the positioning component and the pressing component, enables the user to adjust the lateral position of the safety buckle by sliding the buckle when wearing it for the first time; after the safety buckle is adjusted to the position, the user can press the locking component to limit the buckle after permanent deformation, thereby forming a rigid fixation between the buckle, the positioning component and the pressing component, effectively preventing the buckle from sliding and stretching during subsequent use, and improving the positional stability of the safety buckle during subsequent use;

[0019] (2) Through the structural cooperation of the flat-head screw and the rivet nut, on the one hand, the flat-head screw can limit the buckle along the length direction after being screwed in, so that the buckle will not move laterally relative to the positioning part under the action of external force; on the other hand, it can also improve the connection stability between the positioning part and the pressing part, thereby avoiding the loosening problem caused by the positioning part and the pressing part not being pressed in place, and cooperate with the deformation mechanism to achieve double locking, preventing the positioning part and the pressing part from separating from each other during later use;

[0020] (3) By disassembling the protective clothing into separate protective vests and linings, the linings can be removed from the protective vests and used to install the airbags. On this basis, by connecting the airbags through the limiting components after they are inserted into the placement cavity, the limiting components can be extended to the outside of the placement cavity, which facilitates the fixing operation of the workers. On the other hand, the limiting components and the installation port can be used to limit the airbags after they are flattened, so that the connecting pieces on both sides of the second airbag are blocked by the limiting components and cannot be retracted back into the placement cavity from the installation port. This effectively prevents the airbags from wrinkling and shifting during use, and improves the limiting and flattening effect of the present invention on the airbags.

[0021] (4) By combining the protective vest and the lining, the lining and the airbag can be hidden inside the protective vest, thus using the protective vest to wrap and protect the lining and the airbag; when the protective vest is worn or torn during use, the workers can replace the protective vest separately, reducing the later maintenance cost of the protective clothing.

[0022] (5) By connecting the two sides of the front and back lining with buckle straps, and connecting the two sides of the protective vest with the covering layer, the covering layer can wrap and cover the buckle straps on the inside during normal use to prevent the buckle straps from getting caught on external facilities during use. On the other hand, it can also wrap the body of the worker in the non-inflated state, so that the protective clothing fits the body tightly in this state. When the airbag is inflated, the second snap will be released and the covering layer will be released. Then the buckle straps will achieve the limiting function after being straightened, ensuring the wrapping effect of the protective clothing on the worker in different states.

[0023] Therefore, this utility model can improve the installation stability and limiting effect of the safety lock and airbag. Attached Figure Description

Detailed Implementation

[0037] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0038] Example 1. A protective suit for high-altitude work, comprising as follows: Figure 1-5 As shown, the device includes a protective suit with a safety buckle 1 in the middle. An airbag 2 is fixedly or detachably connected inside the protective suit. A fall protection sensor 3 and an air cylinder 4 are connected to the outside of the protective suit. Both the fall protection sensor 3 and the air cylinder 4 are fixed to the back of the protective suit at the shoulder and neck area according to the existing installation method. The nozzle of the air cylinder 4 passes through the protective suit and communicates with the airbag 2. The fall protection sensor 3 is used to drive the air cylinder 4 to inflate the airbag 2 when it detects that a worker has fallen. The airbag 2 is used to wrap the front and back of the worker's body after inflation, thereby reducing the external impact on the body during a fall.

[0039] The protective suit is a cardigan structure with a first opening on the front. The protective suits on both sides of the first opening are connected to each other by a first zipper. There are multiple safety buckles 1, which are spaced apart at the first opening of the protective suit. The two ends of the safety buckle 1 are connected to the two sides of the protective suit by buckle straps 7 respectively. A locking component is provided on one side of the buckle strap 7. The locking component is used to fix the extension length of the buckle strap 7 by permanent deformation after pressing, so that the buckling position of the safety buckle 1 remains unchanged during subsequent use.

[0040] The back of the protective suit has a deformable opening for inflating the airbag 2.

[0041] The locking assembly includes a positioning element 8 and a pressing element 9. The safety buckle 1 is slidably connected to the buckle 7, and the positioning element 8 is fixedly connected to the buckle 7. The pressing element 9 and the positioning element 8 are distributed vertically. The two ends of the pressing element 9 and the positioning element 8 are connected to each other through a deformation mechanism. A second opening for the buckle 7 to pass through is formed between the two deformation mechanisms. Pressing teeth 10 are provided on the pressing element 9 and the positioning element 8 on both sides of the second opening. The pressing teeth 10 on both sides are staggered along the length of the buckle 7.

[0042] The deformation mechanism includes a limiting piece 901 disposed on the pressing member 9 and a buckle groove 801 disposed on the positioning member 8. The buckle groove 801 has an L-shaped cross-section. There are multiple limiting pieces 901, which are spaced apart along the length of the buckle 7. The lower end of the limiting piece 901 extends to the bottom of the buckle groove 801 and engages with the buckle groove 801.

[0043] The positioning element 8 and the pressing element 9 are connected to each other by a flat-head screw 11. The flat-head screw 11 is staggered relative to the pressing teeth 10. The nut of the flat-head screw 11 is located on the side of the pressing element 9 away from the positioning element 8. The end of the flat-head screw 11 passes through the positioning element 8 and the buckle 7 in sequence and is threaded to the positioning element 8.

[0044] The middle part of the positioning component 8 is connected to the flat-head screw 11 via the rivet nut 12. When installing the flat-head screw 11, the operator can first pass the buckle 7 through the round hole of the pressing component 9 with a self-tapping screw or a spike, and then pass the flat-head screw 11 through the hole and thread it to the rivet nut 12.

[0045] In this embodiment, during use, the operator first passes the buckle 7 through the second opening between the positioning member 2 and the pressing member 9, and then pulls the buckle 7 to adjust the lateral position of the safety lock 1 on the protective suit, so that the protective suit can wrap and tighten around the operator's body after the safety lock 1 is fastened, preventing the protective suit from loosening and falling off. After the buckle 7 is adjusted to the correct position, the operator presses the pressing member 9, causing the pressing member 9 to move towards the positioning member 8 under the pressure, and making the buckle 7 fit tightly against the pressure teeth 10 on both sides. After the positioning member 8 and the pressing member 9 are pressed together, the flat-head screw 11 is screwed in, so that the positioning member 8, the buckle 7 and the pressing member 9 are completely fitted together by the cooperation of the flat-head screw 11 and the rivet nut 12. Then, the end of the limiting piece 901 is bent so that it is flattened and then fastened into the buckle groove 801, thereby completely fixing the positioning member 8 and the pressing member 9 and preventing them from separating during subsequent use. With the above coordination, the buckle 7 can form a rigid limit on the safety lock 1, improving the limiting effect of the safety lock 1 on the protective clothing after it is fastened.

[0046] Example 2. A protective suit for high-altitude work, comprising as follows: Figure 6-11As shown, the device includes a protective suit with a safety buckle 1 in the middle. An airbag 2 is detachably connected inside the suit. A fall arrestor 3 and an air cylinder 4 are connected to the outside of the suit. Both the fall arrestor 3 and the air cylinder 4 are fixed to the back of the protective suit at the shoulder and neck area using the existing installation method. The nozzle of the air cylinder 4 passes through the protective suit and communicates with the airbag 2. The fall arrestor 3 is used to drive the air cylinder 4 to inflate the airbag 2 when a fall is detected. The airbag 2, after inflation, wraps around the front and back of the worker's body, thereby reducing the impact of the fall. The protective suit, which is designed to withstand external impacts upon landing, includes a protective vest 5 and an inner lining 6. The inner lining 6 and the protective vest 5 are nested together and connected to each other. The airbag 2 is detachably connected to the inside of the protective vest 5 via the inner lining 6. The front of the protective vest 5 forms a first opening, and the two sides of the protective vest 5 are connected to each other via a first zipper. There are multiple safety buckles 1, which are spaced apart at the first opening of the protective vest 5. The two ends of the safety buckles 1 are connected to the two sides of the protective vest 5 via buckle straps 7, which are of fixed length or have a length adjustment function.

[0047] The inner lining 6 includes a front lining 601 and a back lining 602, which are connected to each other by a shoulder strap 603. The shoulder strap 603, after the inner lining 6 is installed, is located inside the shoulder area of ​​the protective vest 5 and can be attached to the protective vest 5 via Velcro. Both the front lining 601 and the back lining 602 have placement cavities 604 on their inner sides for accommodating the airbag 2. Several mounting openings 605 are distributed around the placement cavity 604. The airbag 2 includes a first airbag segment 201 located outside the placement cavity 604. Multiple second airbag segments 202 are connected around the perimeter of the airbag 2. Each second airbag segment 202 extends into a placement cavity 604. Several connecting pieces 203 are distributed on both sides of the second airbag segment 202. The ends of the connecting pieces 203 extend to the outside of the inner liner 6 through the mounting port 605 and are detachably connected to a limiting component. The limiting component and the surface of the inner liner 6 are connected to each other through a first snap 13. The limiting component is used to limit the connecting pieces 203 to prevent the connecting pieces 203 from shrinking into the placement cavity 604 as the airbag 2 wrinkles, shakes, or shifts.

[0048] There are two of each of the first airbag component 201 and the second airbag component 202, which are used to protect the front and back of the worker's torso after inflation.

[0049] The protective vest 5 has elongated deformation openings on the back and the middle of the back lining 602 for the second airbag split 202 to bulge normally.

[0050] The connecting piece 203 has a round hole in the middle. The limiting component includes a split screw head 14 and a nut 15. One end of the screw head 14 is connected to the first snap 13, and the other end of the screw head 14 passes through the round hole and is threaded to the nut 15. The outer diameter of the screw head 14 is greater than the length of the mounting opening 605.

[0051] The number of front linings 601 is two, and they are arranged side by side on the left and right sides of the protective vest 5. One side of the front lining 601 is connected to the protective vest 5 via a second zipper. The top of the back lining 602 is hung on the back of the protective vest 5 via a hanging hook.

[0052] The protective vest 5 has a double zipper structure at the middle opening. The first zipper is located on the outside and is used to connect the two protective vests 5 together after being zipped up to wrap the workers. The second zipper is used to connect the protective vest 5 and the inner lining 6 together after being zipped up.

[0053] The front liner 601 and the rear liner 602 are connected to each other on both sides by buckle straps 16. The buckle straps 16 are conventional buckle straps with D-rings. The worker can adjust the length of the straps by using the D-rings, so that the buckle straps 16 are fully straightened after the airbag 2 is inflated, and the protective clothing fits tightly against the worker's body. The protective vest 5 has arm holes on the top of both sides. The lower end of the arm holes is provided with a covering layer 17. One end of the covering layer 17 is fixedly connected to the front edge of the protective vest 5, and the other end of the covering layer 17 is connected to the back edge of the protective vest 5 via a second snap 18.

[0054] The first airbag unit 201 is externally connected to a third airbag unit 204. The top of the protective vest 5 is provided with a neck pocket that works in conjunction with the third airbag unit 204. The third airbag unit 204 is used to protect the back, shoulders and neck of the worker after inflation.

[0055] The first airbag component 201, the second airbag component 202, and the third airbag component 204 are interconnected to form an integrated structure.

[0056] In this embodiment, the protective suit is split from the original one-piece structure into an independent protective vest 5 and inner lining 6. This allows the airbag 2 to be installed by first inserting each second airbag component 202 into the placement cavity 604 of the front lining 601 and the rear lining 602 respectively. Then, the connecting piece 203 on the second airbag component 202 extends out from the mounting port 605 on the side wall of the placement cavity 604 and is connected to the screw head 14 and nut 15. After the screw head 14 and nut 15 are connected, they can limit the connecting piece 203, preventing it from retracting back into the placement cavity 604 from the mounting port 605. This achieves the flattening and fixing of the second airbag component 202 in the placement cavity 604.

[0057] After the airbag 2 and the inner liner 6 are connected, the worker then secures the inner liner 6 with the airbag 2 to the inside of the protective vest 5 using the second zipper and hanging ring, and then fastens the third airbag split 204 into the neck pocket at the top of the protective vest 5, so that the two can be connected to form an integrated protective suit. After the worker puts on the protective suit, the front liner 601 and the back liner 602 are first connected to each other using the buckle straps 16, and then the two sides of the protective vest 5 are connected to each other using the covering layer 17 and the second snap 18. This allows the covering layer 17 to limit the protective vest 5 and the inner liner 6 in the normal state, ensuring that the two fit tightly against the worker's torso. At the same time, the buckle straps 16 are in a bent and relaxed state in this state and are wrapped inside by the covering layer 17.

[0058] When the airbag is inflated, the front liner 601 and the rear liner 602 bulge outwards, exerting an outward pulling force on the covering layer 17 from both sides. This causes the second snap button 18 to disengage under the pulling force, releasing the covering layer 17 from its restraining position on the protective suit. After the second snap button 18 disengages, the buckle straps 16 gradually change from a bent and loose state to a taut and straight state as the front liner 601 and the rear liner 602 inflate, thus replacing the covering layer 17 to restrain the protective suit on both sides, ensuring that the protective suit fits snugly against the worker's torso when inflated, guaranteeing its protective effect.

[0059] Example 3. A protective suit for high-altitude operations, comprising as follows: Figure 12 As shown, the protective suit includes a safety buckle 1 in the middle, an airbag 2 detachably connected inside, and a fall arrest sensor 3 and an air cylinder 4 connected to the outside of the suit. Both the fall arrest sensor 3 and the air cylinder 4 are fixed to the back of the protective suit at the shoulder and neck area using the existing installation method. The nozzle of the air cylinder 4 passes through the protective suit and communicates with the airbag 2. The fall arrest sensor 3 is used to drive the air cylinder 4 to inflate the airbag 2 when a fall is detected. The airbag 2, after inflation, wraps around the front and back of the worker's body, thereby reducing the external impact on the body during a fall. The protective suit also includes a protective vest. The protective vest 5 and the inner lining 6 are nested together and connected to each other. The airbag 2 is detachably connected to the inside of the protective vest 5 via the inner lining 6. The front of the protective vest 5 forms a first opening. The protective vests 5 on both sides of the first opening are connected to each other via a first zipper. There are multiple safety buckles 1, which are spaced apart at the first opening of the protective vest 5. The two ends of the safety buckle 1 are connected to the two sides of the protective vest 5 via buckle straps 7. A locking component is provided on one side of the buckle strap 7. The locking component is used to fix the extension length of the buckle strap 7 through permanent deformation after pressing, so that the buckle 1 remains in the same position.

[0060] The locking component is the locking component in Embodiment 1.

[0061] The protective vest 5, the lining 6, and the airbag 2 are connected to each other using the connection method of Embodiment 2.

[0062] This embodiment integrates the safety buckle 1 connection structure of Embodiment 1 and the airbag 2 installation structure of Embodiment 2 into the same protective suit, which can simultaneously improve the installation stability and limiting effect of the safety buckle and the airbag, and facilitate user use.
