Description

Technical Field

[0001] The present invention relates to a high-altitude operation protection facility, in particular to a high-altitude operation protection device based on an inflatable protection structure. Background Art

[0002] A high-altitude operation protective clothing is a protection facility that provides comprehensive protection for operators during aerial operations above 2 meters. An airbag, an inflatable bottle, and a fall prevention sensor are installed in the protective clothing; when the operator accidentally falls during work, the fall prevention sensor drives the inflatable bottle to inflate the airbag after sensing, so that the airbag wraps the operator's body after inflation, thereby buffering the upward impact force generated by the collision of the body with the ground or other objects during the falling process, and protecting parts such as the spine and back muscles from damage.

[0003] On this basis, the existing high-altitude operation protective clothing is generally in the form of a vest. A full zipper and a safety buckle are installed on the front of the protective clothing, and buckle straps are installed on both sides of the protective clothing. When the operator wears it, first close the zipper so that the protective clothing can completely wrap the operator's body after the zipper is closed, and then insert the safety buckle to secondarily limit the protective clothing with the safety buckle, preventing the protective clothing from shifting or falling due to the zipper being torn open during the operator's operation or fall, and ensuring the protection effect of the protective clothing. The buckle straps on both sides of the protective clothing are in a loose state in the non-inflated state and play a lateral limiting function on the protective clothing, that is, preventing the lower end of the protective clothing from swaying left and right during operation; when the airbag is inflated, the buckle straps gradually straighten as the protective clothing on both sides expands, and play a limiting function on the airbags on the front and back sides of the protective clothing, so that the airbags can closely adhere to the body after expansion, ensuring the wrapping and protection effect of the airbags.

[0004] However, the above structure has certain defects in actual use. First, there are two installation methods for the safety buckle on the existing protective clothing. The first is to directly hoist the buckle on the protective clothing through a looped strap. The advantage of this structure is that the buckle is not prone to loosening, disconnection, or deviation after being fastened. However, the defect is that the lateral position of the buckle cannot be adjusted, resulting in the protective clothing being relatively loose or overly tight after being fastened, depending on the differences in the wearer's body size, and its protective effect cannot reach the best. The second method is to add a D-ring for adjusting the length in the middle of the strap, enabling the operator to achieve the best wrapping and protective effect of the protective clothing by adjusting the length of the strap. However, the defect of this structure is that the D-ring is only limited by the friction with the strap, resulting in, on the one hand, the friction resistance on the strap gradually decreasing with the long-term use of the user, causing the safety buckle to easily move and shift due to the wearing and pulling actions, affecting the tightening effect of the protective clothing; on the other hand, once the strap is pulled by an external force during operation or dropping, it is also prone to form a lateral slide and directly loosen the safety buckle, thereby reducing the protective effect of the safety buckle.

[0005] Second, in order to achieve the separate replacement of the airbag for the existing protective clothing, the protective clothing and the airbag are generally made into a split structure and used in combination. Specifically, several pockets for accommodating the airbag are opened on the inner side of the protective clothing, and then each part of the airbag is respectively inserted into the pocket of the protective clothing. When the airbag needs to be removed later, the operator can directly pull out the airbag from the bag opening to separate the two, thus facilitating the replacement of the airbag by the operator. Although this structure can achieve the separate replacement of the airbag, since there is no corresponding limiting measure for the airbag after it is inserted into the pocket, the flat airbag is prone to problems such as wrinkling and deviation during use with the operator's twisting, which will further hinder the inflation of the airbag, causing the local position of the airbag to not bulge in time and posing a safety hazard. If fixing parts such as Velcro and snap buttons are used to limit the end corners of the airbag, on the one hand, since these fixing parts are all arranged on the inner side of the protective vest, it will increase the difficulty for the operator to flatten and fix the airbag; on the other hand, the airbag is also prone to being disengaged under force during subsequent use, and its fixing effect is not ideal.

[0006] Therefore, the existing high-altitude operation protective clothing has problems of poor installation stability and limiting effect for the safety buckle and the airbag. Summary of the Invention

[0007] The purpose of the present invention is to provide a high-altitude operation protection device based on an inflatable protection structure, which can improve the installation stability and limiting effect for the safety buckle and the airbag.

[0008] Technical solution of the present invention: An aerial work protection device based on an inflatable protection structure, including a protective suit. A safety buckle is provided in the middle of the protective suit. An airbag is detachably connected inside the protective suit. An anti-falling sensor and a gas cylinder are respectively connected to the outside of the protective suit. The protective suit includes a protective vest and a lining. The lining and the protective vest are nested and connected to each other inside and outside. The airbag is detachably connected to the inner side of the protective vest through the lining. A first opening is formed on the front of the protective vest. The protective vests on both sides of the first opening are connected to each other through a first zipper. The number of safety buckles is multiple and they are arranged at intervals at the first opening of the protective vest. Both ends of the safety buckle are respectively connected to the protective vests on both sides through buckle straps. A locking component is provided on one buckle strap. The locking component is used to fix the extended length of the buckle strap through permanent deformation after being pressed, so that the buckling position of the safety buckle remains unchanged.

[0009] In the aforementioned aerial work protection device based on an inflatable protection structure, the locking component includes a positioning member and a pressing member. The safety buckle is slidably connected to the buckle strap. The positioning member is fixedly connected to the buckle strap. The pressing member and the positioning member are distributed up and down. Both ends of the pressing member and the positioning member are connected to each other through a deformation mechanism. A second opening for the buckle strap to pass through is formed between the two ends of the deformation mechanism. Pressing teeth are provided on the pressing member and the positioning member on both sides of the second opening.

[0010] In the aforementioned aerial work protection device based on an inflatable protection structure, the deformation mechanism includes a limiting piece provided on the pressing member and a buckle groove provided on the positioning member. The cross-sectional shape of the buckle groove is L-shaped. The number of limiting pieces is multiple and they are arranged at intervals along the length direction of the buckle strap. The lower end of the limiting piece extends to the bottom of the buckle groove and is buckled with the buckle groove.

[0011] In the aforementioned aerial work protection device based on an inflatable protection structure, the positioning member and the pressing member are connected to each other through a flat head screw. The nut of the flat head screw is located on the side of the pressing member away from the positioning member. The end of the flat head screw sequentially passes through the positioning member and the buckle strap and is threadedly connected to the positioning member.

[0012] In the aforementioned aerial work protection device based on an inflatable protection structure, the lining includes a front lining and a rear lining. The front lining and the rear lining are connected to each other through shoulder straps. Placement cavities for accommodating the airbag are provided on the inner sides of the front lining and the rear lining. A number of installation openings are distributed around the placement cavities. The airbag includes a first airbag split body located outside the placement cavity. A plurality of second airbag split bodies are connected to the periphery of the first airbag split body. Each second airbag split body extends into a placement cavity respectively. A number of connecting pieces are distributed on both sides of the second airbag split body. The ends of the connecting pieces extend to the outside of the lining through the installation openings and are detachably connected to a limiting component. The limiting component and the surface of the lining are connected to each other through a first snap button. The limiting component is used to limit the connecting pieces to prevent the connecting pieces from shrinking into the placement cavity.

[0013] In the aforementioned aerial work protection device based on an inflatable protection structure, a round hole is provided in the middle of the connecting piece. The limiting component includes a split screw head and a nut. One end of the screw head is connected to the first snap fastener, the other end of the screw head passes through the round hole and is threadedly connected to the nut, and the outer diameter of the screw head is greater than the length of the installation opening.

[0014] In the aforementioned aerial work protection device based on an inflatable protection structure, the number of the front linings is two, and they are arranged side by side on the left and right sides of the protective vest. One side of the front lining is connected to the protective vest through a second zipper; the top of the rear lining is hooked to the back of the protective vest through a hanging ring.

[0015] In the aforementioned aerial work protection device based on an inflatable protection structure, the two sides of the front lining and the rear lining are connected to each other through snap fastener straps; arm holes are provided at the top of both sides of the protective vest, and a covering layer is provided at the lower end of the arm hole. 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 through a second snap fastener.

[0016] In the aforementioned aerial work protection device based on an inflatable protection structure, a third airbag segment is externally connected to the outside of the first airbag segment, and a neck bag for cooperating with the third airbag segment is provided at the top of the protective vest.

[0017] Compared with the prior art, the present invention has the following characteristics:

[0018] (1) Through the structural cooperation of the positioning member and the pressing member, the user can adjust the lateral position of the safety lock through the sliding buckle during the first wearing; when the safety lock is adjusted in place, the user can press the locking component to limit the buckle after permanent deformation, so as to form a rigid fixation among the buckle, the positioning member and the pressing member, effectively preventing the sliding and telescoping of the buckle during subsequent use, and improving the position stability of the safety lock 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 in the length direction after being screwed in, so that the buckle will not have the problem of lateral movement relative to the positioning member under the action of external force; on the other hand, it can also improve the connection stability between the positioning member and the pressing member, thus avoiding the loosening problem caused by the improper pressing of the positioning member and the pressing member, and cooperating with the deformation mechanism to achieve double locking for them, preventing the separation of the positioning member and the pressing member during later use;

[0020] (3) By splitting the protective suit into a split protective vest and an inner liner, the inner liner can be removed from the protective vest separately and used to install the airbag; on this basis, by connecting the airbag through a limiting component after inserting it into the placement cavity, on the one hand, the limiting component can be extended to the outside of the placement cavity, thereby facilitating the fixing operation of the operator; on the other hand, the cooperation between the limiting component and the installation port can be used to limit the position of the airbag after flattening, so that the connecting pieces on both sides of the second airbag split are blocked by the limiting component and cannot be retracted from the installation port into the placement cavity, that is, the wrinkling and displacement of the airbag during use are effectively prevented, thereby improving the limiting and flattening effect of the present invention on the airbag;

[0021] (4) By combining the protective vest and the liner, the liner and the airbag can be hidden together inside the protective vest, so that the liner and the airbag can be wrapped and protected by the protective vest; and when the protective vest is worn or scratched during use, the operator can replace the protective vest separately, thereby reducing the subsequent maintenance cost of the protective clothing;

[0022] (5) By connecting the two sides of the front lining and the back lining to each other through the buckle straps, and connecting the two sides of the protective vest to each other through the covering layer, the covering layer can, on the one hand, wrap and shield the inner buckle straps during normal use to prevent the buckle straps from being hooked on external facilities during use, and on the other hand, can replace the buckle straps to wrap the body of the worker in the non-inflated state, so that the protective clothing fits the body tightly in this state; and when the airbag is inflated, the second snap button will be forced to disengage and release the wrapping of the covering layer, and then the buckle strap will realize the limiting function after being straightened, thereby ensuring the wrapping effect of the protective clothing on the worker in different states;

[0023] Therefore, the present invention can improve the installation stability and limiting effect of the safety lock buckle and the airbag. BRIEF DESCRIPTION OF THE DRAWINGS

A safety buckle 1 is provided in the middle of the protective suit. An airbag 2 is fixedly connected or detachably connected inside the protective suit. An anti - fall sensor 3 and a gas cylinder 4 are respectively connected to the outside of the protective suit. Both the anti - fall sensor 3 and the gas cylinder 4 are fixed at the back shoulder and neck of the protective suit in the existing installation manner. The nozzle of the gas cylinder 4 passes through the protective suit and communicates with the airbag 2; the anti - fall sensor 3 is used to drive the gas cylinder 4 to inflate the airbag 2 when it detects that the operator has a falling situation, and the airbag 2 is used to wrap the front and back bodies of the operator after inflation, so as to reduce the external impact suffered by the body during a fall;

[0039] The protective clothing is of a cardigan structure and forms a first opening on the front. The protective clothing on both sides of the first opening is connected to each other by a first zipper. The number of the safety buckles 1 is multiple and they are arranged at intervals at the first opening of the protective clothing. Both ends of the safety buckle 1 are respectively connected to the protective clothing on both sides through the buckle straps 7, and a locking assembly is provided on one side of the buckle strap 7; the locking assembly is used to fix the extending length of the buckle strap 7 through permanent deformation after being pressed, so that the buckling position of the safety buckle 1 remains unchanged during subsequent use.

[0040] A deformation opening for the airbag 2 to inflate and bulge is provided on the back of the protective clothing.

[0041] The locking assembly includes a positioning member 8 and a pressing member 9. The safety buckle 1 is slidably connected to the buckle strap 7. The positioning member 8 is fixedly connected to the buckle strap 7. The pressing member 9 and the positioning member 8 are distributed up and down. Both ends of the pressing member 9 and the positioning member 8 are connected to each other through a deformation mechanism. A second opening for the buckle strap 7 to pass through is formed between the two ends of the deformation mechanism. Pressing teeth 10 are provided on both the pressing member 9 and the positioning member 8 on both sides of the second opening. The pressing teeth 10 on both sides are arranged in a front-back dislocation along the length direction of the buckle strap 7.

[0042] The deformation mechanism includes a limiting piece 901 provided on the pressing member 9 and a buckle groove 801 provided on the positioning member 8. The cross-sectional shape of the buckle groove 801 is L-shaped. The number of the limiting pieces 901 is multiple and they are arranged at intervals along the length direction of the buckle strap 7. The lower end of the limiting piece 901 extends to the bottom of the buckle groove 801 and is buckled with the buckle groove 801.

[0043] The positioning member 8 and the pressing member 9 are connected to each other through a flat head screw 11. The flat head screw 11 is arranged in a front-back dislocation relative to the pressing teeth 10. The nut of the flat head screw 11 is located on the side of the pressing member 9 away from the positioning member 8. The end of the flat head screw 11 sequentially passes through the positioning member 8 and the buckle strap 7 and is threadedly connected to the positioning member 8.

[0044] The middle part of the positioning member 8 is connected to the flat head screw 11 through a rivet nut 12; when installing the flat head screw 11, an operator can first perforate the buckle strap 7 through a self-tapping screw or a spike from the round hole of the pressing member 9, and then pass the flat head screw 11 through the perforation and threadedly connect it to the rivet nut 12.

[0045] When this embodiment is in use, the operator first passes the buckle strap 7 through the second opening between the positioning member 2 and the pressing member 9, and then pulls the buckle strap 7 to adjust the lateral position of the safety buckle 1 on the protective clothing, so that the protective clothing can wrap and tighten the operator's body after the safety buckle 1 is fastened, preventing the protective clothing from loosening and falling off. After the buckle strap 7 is adjusted in place, the operator then presses the pressing member 9, so that the pressing member 9 moves towards the positioning member 8 under the pressing action, and the buckle strap 7 closely fits with the two side pressing teeth 10 along with the pressing. 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 strap 7 and the pressing member 9 are completely fitted with each other 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 buckled into the buckle groove 801 after being flattened, so that the positioning member 8 and the pressing member 9 are completely fixed, preventing the two from separating from each other during subsequent use. With the above cooperation, the buckle strap 7 can form a rigid limit on the safety buckle 1, improving the limiting effect of the safety buckle 1 on the protective clothing after being fastened.

[0046] Embodiment 2. An aerial work protection device based on an inflatable protection structure, the composition is as Figures 6-11 shown, including a protective clothing, a safety buckle 1 is provided in the middle of the protective clothing, an airbag 2 is detachably connected inside the protective clothing, a fall prevention sensor 3 and a gas cylinder 4 are respectively connected to the outside of the protective clothing, the fall prevention sensor 3 and the gas cylinder 4 are both fixed at the back shoulder and neck of the protective clothing according to the existing installation method, and the nozzle of the gas cylinder 4 passes through the protective clothing and communicates with the airbag 2; the fall prevention sensor 3 is used to drive the gas cylinder 4 to inflate the airbag 2 when detecting that the operator has a falling situation, and the airbag 2 is used to wrap the front and back bodies of the operator after inflation, so as to reduce the external impact on the body during the fall. The protective clothing includes a protective vest 5 and a lining 6, and the lining 6 and the protective vest 5 are nested and connected with each other inside and outside. The airbag 2 is detachably connected to the inner side of the protective vest 5 through the lining 6; a first opening is formed on the front of the protective vest 5, and the protective vest 5 on both sides of the first opening is connected by a first zipper. The number of the safety buckles 1 is multiple and they are arranged at intervals at the first opening of the protective vest 5. Both ends of the safety buckle 1 are respectively connected to the protective vests 5 on both sides through a buckle strap 7, and the buckle strap 7 is of a fixed length or has a length adjustment function.

[0047] The inner lining 6 includes a front lining 601 and a rear lining 602. The front lining 601 and the rear lining 602 are interconnected by a shoulder strap 603. After the inner lining 6 is installed, the shoulder strap 603 is located inside the shoulder of the protective vest 5 and can be adhesively attached to the protective vest 5 through Velcro; on the inner sides of both the front lining 601 and the rear lining 602, there are placement cavities 604 for accommodating the airbag 2, and a number of mounting openings 605 are distributed around the placement cavity 604; the airbag 2 includes a first airbag section 201 located outside the placement cavity 604, and a plurality of second airbag sections 202 are connected around the first airbag section 201. Each second airbag section 202 extends into a placement cavity 604 respectively. On both sides of the second airbag section 202, there are a number of connecting pieces 203. The ends of the connecting pieces 203 extend to the outside of the inner lining 6 through the mounting openings 605 and are detachably connected to a limiting assembly. The limiting assembly and the surface of the inner lining 6 are interconnected by a first snap button 13; the limiting assembly is used to limit the connecting pieces 203 to prevent the connecting pieces 203 from shrinking into the placement cavity 604 due to the folding, shaking or offset of the airbag 2.

[0048] The number of both the first airbag section 201 and the second airbag section 202 is two, and they are respectively used to protect the front torso and the back torso of the operator after inflation.

[0049] On the back of the protective vest 5 and in the middle of the rear lining 602, there are long strip-shaped deformation openings for the normal bulging of the second airbag section 202.

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

[0051] The number of the 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 through a second zipper; the top of the rear lining 602 is hooked on the back of the protective vest 5 through a hanging ring.

[0052] The middle opening of the protective vest 5 is a double-zipper structure. The first zipper is located on the outside and is used to connect the two sides of the protective vest 5 after being zipped up and wrap the operator, and the second zipper is used to connect the protective vest 5 and the inner lining 6 after being zipped up.

[0053] Both sides of the front lining 601 and the rear lining 602 are connected to each other by the buckle strap 16. The buckle strap 16 is a conventional buckle strap with a D-ring. The operator can adjust the length of the strap through the D-ring, so that the buckle strap 16 is completely straightened after the airbag 2 is inflated and the protective clothing fits tightly against the operator's body. Armholes are provided at the top of both sides of the protective vest 5. A covering layer 17 is provided at the lower end of the armhole. 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 rear edge of the protective vest 5 through the second snap button 18.

[0054] The third airbag unit 204 is connected to the outside of the first airbag unit 201. A neck pocket for cooperating with the third airbag unit 204 is provided at the top of the protective vest 5. The third airbag unit 204 is used to protect the back, shoulders and neck of the operator after inflation.

[0055] The first airbag unit 201, the second airbag unit 202 and the third airbag unit 204 communicate with each other to form an integrated structure.

[0056] In this embodiment, the protective clothing is split from the original integrated structure into the independent protective vest 5 and the inner lining 6, so that when installing the airbag 2, the second airbag units 202 can be respectively inserted into the placement cavities 604 of the front lining 601 and the rear lining 602 first, and then the connecting pieces 203 on the second airbag units 202 are extended from the installation openings 605 on the side walls of the placement cavities 604 and then connected to the screw heads 14 and the nuts 15, so that the screw heads 14 and the nuts 15 can limit the connecting pieces 203 after connection, and the connecting pieces 203 cannot retract back into the placement cavities 604 from the installation openings 605 due to the obstruction of the two, thereby realizing the flattening and fixing of the second airbag units 202 in the placement cavities 604.

[0057] After the airbag 2 and the inner lining 6 are connected to each other, the operator then fixes the inner lining 6 with the airbag 2 on the inner side of the protective vest 5 through the second zipper and the hanging rings, and buckles the third airbag unit 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 clothing. When the operator puts on the protective clothing, first connect both sides of the front lining 601 and the rear lining 602 through the buckle strap 16, and then connect the two sides of the front and back of the protective vest 5 through the cooperation of the covering layer 17 and the second snap button 18, so that the covering layer 17 can limit the protective vest 5 and the inner lining 6 in the normal state, ensure that the two are close to the operator's torso in this state, and at the same time the buckle strap 16 is in a bent and relaxed state in this state and is wrapped inside by the covering layer 17.

[0058] After the airbag is inflated, the front lining 601 and the rear lining 602 bulge outwards with the inflation, and then apply an outward pulling force on the covering layer 17 from the front and rear sides, causing the second snap fastener 18 to be unfastened and separated under the action of the pulling force, and the covering layer 17 releases the limit on the protective clothing. After the second snap fastener 18 is unfastened, the buckle strap 16 gradually changes from a bent and relaxed state to a tight and straight state as the front lining 601 and the rear lining 602 bulge with inflation, thereby replacing the covering layer 17 to achieve the lateral limit on the protective clothing, ensuring that the protective clothing fits tightly against the torso of the operator in the inflated state and ensuring its protective effect.
