Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of labor protection articles, in particular to an antistatic protective clothing with anti-tearing function. BACKGROUND

[0002] During operation, the protective clothing is easily hooked and pulled by the sharp edges of equipment, metal components, rocks, etc., leading to tearing of the fabric and loss of protective barrier, directly exposing the personnel to a dangerous environment. Traditional protective clothing often has the problem of "emphasizing single function and ignoring collaborative protection". Either it only has antistatic performance but poor tear resistance, or it focuses on anti-tearing but has no static protection design, which cannot meet the protection needs in complex and high-risk scenarios.

[0003] The patent with patent announcement number CN215381608U relates to the technical field of antistatic protective clothing, specifically an antistatic protective clothing with anti-tearing function, comprising a protective clothing body, the protective clothing body includes a hat, a front block is fixedly connected below the hat, a rear block is arranged on one side of the front block, the rear block is fixedly connected with the hat, two waist elastic devices are fixedly connected between the front block and the rear block, the waist elastic device includes a waist folding cloth. The utility model has the advantages that when the protective clothing is used by a user with a slim body, the elastic band is in a contracted state at this time, the elastic band will pull the front block and the rear block to the middle at this time, the waist folding cloth is in a folded state at this time, so that the protective clothing is reduced to be suitable for a slim person to wear according to the body of the user, and the practicality of the protective clothing is improved.

[0004] The above-mentioned patent has obvious limitations in practice: when the workers are working, the protective clothing is often hooked by equipment, and when there is no self-detaching anti-tearing layer on the basis of the protective clothing, the wearer cannot detach the outer layer by physical pulling, but can only struggle passively, which may cause the body to be dragged and hit the equipment, causing bumps and crush injuries. SUMMARY

[0005] In view of the deficiencies of the prior art, the present application provides an antistatic protective clothing with anti-tearing function, which solves the problems raised in the above background art.

[0006] To achieve the above purpose, the present application is realized by the following technical scheme: an antistatic protective clothing with anti-tearing function, comprising a protective clothing body, a wearing layer is arranged inside the protective clothing body, a protection layer is arranged on the surface of the wearing layer, a sleeve opening is arranged on the front side of the protection layer, and a detachment layer is arranged on the outer side of the protection layer, the protective clothing further comprises:

[0007] a gear is rotatably installed on the surface of the protection layer;

[0008] A threaded cylinder, which is fixedly mounted on the surface of the gear;

[0009] A threaded rod, which is fixedly installed on the inner wall of the threaded cylinder;

[0010] A turntable, which is fitted onto the surface of a threaded rod;

[0011] A sliding sleeve, the sliding sleeve being threaded onto the circumferential surface of the threaded rod;

[0012] A collar is rotatably mounted on the inner wall of a sliding sleeve. The movement of the rack causes the gear to rotate clockwise, which in turn drives the threaded cylinder to rotate clockwise. The clockwise rotation of the threaded cylinder causes the threaded rod to rotate clockwise, which in turn causes the sliding sleeve to retract the collar.

[0013] A connecting buckle is disposed between the release layer and the collar;

[0014] An escape device used to actively sacrifice the non-core layer to protect the core protective layer and enable emergency escape is installed on the surface of the protective layer.

[0015] A shrinking device for shrinking the cuffs is provided on the surface of the protective layer;

[0016] An auxiliary device for assisting detachment in emergency situations is installed on the surface of the protective layer.

[0017] According to the above technical solution, the cuff is provided with an elastic band inside, the breaking threshold of the connecting buckle is set to be greater than the normal human body's pulling force and less than the dangerous tearing force, the number of connecting buckles is set to several, the protective clothing is designed as a double-layer structure with an outermost release layer and an inner protective layer, the two layers are connected by connecting buckles, when the protective clothing release layer is hooked by a heavy object and generates a tearing force exceeding the threshold, the connecting buckle will automatically break, so that the outer layer and the inner layer separate, avoiding injury to the human body from being dragged by heavy objects, while the inner protective layer can still provide basic protection.

[0018] According to the above technical solution, the disengagement device further includes a slide rail, a rack, a wheel rail, and a pull rope. The slide rail is fixedly installed inside the protective layer. The rack is slidably installed on the inner wall of the slide rail. The wheel rail is rotatably installed on the inner wall of the protective layer. The pull rope is in contact with the wheel rail. One end of the pull rope is fixedly installed on the surface of the rack near the wheel rail. The rack meshes with a gear. A torsion spring is provided between the wheel rail and the protective layer. The torsion spring drives the wheel rail to reset. The pull rope is pulled outward by the wheel rail and drives the rack to move along the slide rail.

[0019] According to the above technical solution, the disengagement device further includes a limiting rod and a contact rod. The limiting rod is slidably installed on the inner wall of the protective layer, and the contact rod is fixedly installed on the surface of the rack near the wheel rail. The surface of the wheel rail is provided with a gear slot. The limiting rod contacts the gear slot. A first spring is provided between the limiting rod and the protective layer. The first spring drives the limiting rod to reset. The surface of the limiting rod near the gear slot is set as an arc surface, and the surface of the contact rod near the wheel rail is set as an arc surface. The limiting rod, under the setting of the first spring, limits the insertion of the gear slot. When it is necessary to return to the initial state, the limiting rod can be pulled outward to disengage the gear slot. At this time, the first torsion spring resets the wheel rail, causing the rack to drive the gear to reset.

[0020] According to the above technical solution, the shrinking device includes a protective shell, an adjusting rod, and a ratchet. The protective shell is disposed on the surface of the protective layer. The adjusting rod is rotatably mounted on the inner wall of the cuff. The ratchet is fixedly mounted on the circumferential surface of the adjusting rod. The elastic band is in contact with the adjusting rod. The range of the elastic band inside the cuff is adjusted by rotating the adjusting rod. When rotated counterclockwise, it is taut, and when rotated clockwise, it is loose.

[0021] According to the above technical solution, the retraction device further includes a brake rod and a hinge rod. The brake rod is rotatably mounted on the surface of the protective layer, and the hinge rod is hinged to the surface of the brake rod. The bottom of the brake rod is set as an arc surface. A second torsion spring is provided between the brake rod and the protective layer. The brake rod is reset by the second torsion spring. A third torsion spring is provided between the brake rod and the hinge rod. The hinge rod is reset by the third torsion spring. The brake rod drives the pawl to rotate to the right, so that the pawl disengages from the ratchet.

[0022] According to the above technical solution, the retraction device further includes a pawl and a reset rod. The pawl is fixedly installed on the top of the hinge rod, and the reset rod is slidably installed on the inner wall of the protective shell. A second spring is provided between the reset rod and the protective shell. The reset rod is reset by the second spring. The top of the pawl is set as an inclined surface. By moving the reset rod to the left, the reset rod contacts the brake rod, causing the pawl to rotate to the right and disengage from the ratchet. At this time, the ratchet can rotate clockwise normally.

[0023] According to the above technical solution, the auxiliary device includes a housing, a storage rail, and a ceramic cutting disc. The housing is fixedly installed on the surface of the protective layer. The storage rail is disposed on the inner wall of the housing. The ceramic cutting disc is slidably installed on the inner wall of the storage rail. A groove is provided at the bottom of the ceramic cutting disc. A No. 3 spring is provided inside the storage rail. The No. 3 spring drives the ceramic cutting disc to pop out. An emergency detachment is assisted by a hidden ceramic cutting disc inside the housing. The ceramic cutting disc is placed inside the storage rail and compresses the No. 3 spring.

[0024] According to the above technical solution, the auxiliary device further includes a round rod, a sliding button, and a stop rod. The round rod is rotatably mounted on the surface of the housing. The sliding button is threaded onto the circumferential surface of the round rod. The stop rod is rotatably mounted on the surface of the sliding button. A No. 4 torsion spring is provided between the stop rod and the sliding button. The No. 4 torsion spring drives the stop rod to reset. The stress of the stop rod will not be pushed by the ceramic cutting disc under normal force. The round rod is connected to the adjusting rod by a belt drive. A threaded groove is opened on the circumferential surface of the round rod. When the adjusting rod rotates, it drives the belt to rotate the round rod. The rotation of the round rod, with the setting of the threaded groove, drives the sliding button to reciprocate. The movement of the sliding button drives the stop rod to move.

[0025] According to the above technical solution, it also includes a connecting frame, an abutment button, and a return spring. The connecting frame is fixedly installed on the inner wall of the housing. The abutment button is slidably installed on the inner wall of the connecting frame. The return spring is disposed between the abutment button and the connecting frame. The abutment button is reset by the reset spring. The top of the abutment button is set as an arc surface, so that the sliding groove at the bottom of the ceramic cutting disc moves in close contact with the arc surface of the abutment button. When the end of the sliding groove contacts the arc surface of the abutment button, it blocks the movement of the ceramic cutting disc.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. In this invention, the protective suit is designed as a double-layer structure with an outermost release layer and an inner protective layer by setting a release device. The two layers are connected by a buckle. The breaking threshold of the buckle is set to be greater than the pulling force of normal human activity but less than the dangerous tearing force. When the release layer of the protective suit is hooked by a heavy object and generates a tearing force exceeding the threshold, the buckle will automatically break, so that the outer layer and the inner layer are separated, avoiding injury to the human body from being dragged by heavy objects. The inner protective layer can still provide basic protection and prevent skin abrasions. The tightness of the buckle can be adjusted by pulling the pull rope.

[0028] 2. In this invention, the elastic band inside the cuff is adjusted by rotating the adjustment rod through a shrinking device. The self-locking structure of the ratchet and pawl stabilizes the tightening force of the cuff. Traditional self-locking structures tend to tighten further under strong pulling, which can prevent the cuff from loosening quickly during an emergency and delay escape time. When the connecting buckle reaches the maximum locking position due to extreme pulling (about to trigger the outer layer to detach), the cuff tightening structure is already in a completely relaxed state. Once the outer layer detaches, the wrist can be directly removed from the cuff without additional unlocking operations, shortening the escape response time and significantly increasing the survival probability in high-risk scenarios.

[0029] 3. In this invention, by setting up an auxiliary device, when workers encounter danger (such as when their protective clothing is caught), they need to find additional cutting tools, which delays their escape time. Moreover, the tools are inconvenient to carry and easy to lose. By setting up a hidden ceramic cutting disc inside the housing to assist in emergency detachment, and by setting up a stop rod and a stop button to prevent the ceramic cutting disc from being accidentally triggered and falling out, the grip of the ceramic cutting disc is exposed outside the housing. At this time, the ceramic cutting disc can be released from the restriction of the stop rod and the stop button by pulling it manually, and emergency cutting can be performed.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Please see Figures 1-12 One embodiment of the present invention is: an antistatic protective suit with tear-resistant function, comprising a protective suit body 1, a wearing layer 2 disposed inside the protective suit body 1, a protective layer 3 disposed on the surface of the wearing layer 2, a cuff 4 disposed on the front side of the protective layer 3, and a release layer 5 disposed on the outer side of the protective layer 3; the protective suit further includes:

[0046] Gear 10, gear 10 is rotatably mounted on the surface of protective layer 3;

[0047] Threaded sleeve 11 is fixedly mounted on the surface of gear 10;

[0048] Threaded rod 12 is fixedly installed on the inner wall of threaded cylinder 11;

[0049] Turntable 13 is fitted onto the surface of threaded rod 12;

[0050] The sliding sleeve 14 is threaded onto the circumferential surface of the threaded rod 12. Through the sleeve connection between the turntable 13 and the collar 15, the release layer 5 can move freely within a large range, so that the concentrated tensile force is distributed to the entire contact surface of the connecting buckle 16, avoiding local stress overload.

[0051] The collar 15 is rotatably mounted on the inner wall of the sliding sleeve 14;

[0052] Connecting buckle 16 is disposed between the release layer 5 and the collar 15;

[0053] The detachment device, which is used to actively sacrifice the non-core layer to protect the core protective layer 3 and realize emergency escape, is installed on the surface of the protective layer 3.

[0054] A shrinking device for shrinking the cuff 4 is provided on the surface of the protective layer 3;

[0055] An auxiliary device for assisting detachment in emergency situations is installed on the surface of the protective layer 3.

[0056] The cuff 4 has an elastic band inside. The breaking threshold of the connecting buckle 16 is set to be greater than the normal pulling force of human body activity but less than the dangerous tearing force. The number of connecting buckles 16 is set to a certain number. When the protective clothing separation layer 5 is hooked by a heavy object and generates a tearing force exceeding the threshold, the connecting buckle 16 will automatically break, so that the outer layer and the inner layer are separated, avoiding the human body being dragged and injured by heavy objects. The inner protective layer 3 can still provide basic protection and prevent skin abrasions.

[0057] The disengagement device also includes a slide rail 17, a rack 18, a wheel rail 19, and a pull rope 110. The slide rail 17 is fixedly installed inside the protective layer 3. The rack 18 is slidably installed on the inner wall of the slide rail 17. The wheel rail 19 is rotatably installed on the inner wall of the protective layer 3. The pull rope 110 is in contact with the wheel rail 19. One end of the pull rope 110 is fixedly installed on the surface of the rack 18 near the wheel rail 19. The rack 18 meshes with the gear 10. When it is necessary to return to the initial state, the stop groove can be disengaged by pulling the limit rod 111 outward. A torsion spring is provided between the wheel rail 19 and the protective layer 3. The wheel rail 19 is reset by the torsion spring.

[0058] The disengagement device also includes a limiting rod 111 and a contact rod 112. The limiting rod 111 is slidably installed on the inner wall of the protective layer 3, and the contact rod 112 is fixedly installed on the surface of the rack 18 near the wheel rail 19. The surface of the wheel rail 19 is provided with a gear groove, and the limiting rod 111 contacts the gear groove. A first spring is provided between the limiting rod 111 and the protective layer 3. The first spring drives the limiting rod 111 to reset. The surface of the limiting rod 111 near the gear groove is set as an arc surface, and the surface of the contact rod 112 near the wheel rail 19 is set as an arc surface.

[0059] The shrinking device includes a protective shell 20, an adjusting rod 21, and a ratchet 22. The protective shell 20 is disposed on the surface of the protective layer 3. The adjusting rod 21 is rotatably mounted on the inner wall of the cuff 4. The ratchet 22 is fixedly mounted on the circumferential surface of the adjusting rod 21. The elastic band is in contact with the adjusting rod 21. The range of the elastic band inside the cuff 4 is adjusted by rotating the adjusting rod 21.

[0060] The retraction device also includes a brake rod 23 and a hinge rod 24. The brake rod 23 is rotatably mounted on the surface of the protective layer 3, and the hinge rod 24 is hinged to the surface of the brake rod 23. The bottom of the brake rod 23 is set as an arc surface. A second torsion spring is provided between the brake rod 23 and the protective layer 3. The brake rod 23 is reset by the second torsion spring. A third torsion spring is provided between the brake rod 23 and the hinge rod 24. The hinge rod 24 is reset by the third torsion spring.

[0061] The shrinking device also includes a pawl 25 and a reset rod 26. The pawl 25 is fixedly installed on the top of the hinge rod 24, and the reset rod 26 is slidably installed on the inner wall of the protective shell 20. A second spring is provided between the reset rod 26 and the protective shell 20. The reset rod 26 is reset by the second spring. The top of the pawl 25 is set as an inclined surface. Traditional Velcro is easy to loosen, and repeated pasting will cause wear on the fabric fibers. The self-locking structure of the ratchet 22 and the pawl 25 makes the tightening force of the cuff 4 stable.

[0062] The auxiliary device includes a housing 30, a storage rail 31, and a ceramic cutting disc 32. The housing 30 is fixedly installed on the surface of the protective layer 3. The storage rail 31 is set on the inner wall of the housing 30. The ceramic cutting disc 32 is slidably installed on the inner wall of the storage rail 31. The bottom of the ceramic cutting disc 32 is provided with a sliding groove. A No. 3 spring is set inside the storage rail 31. The No. 3 spring drives the ceramic cutting disc 32 to pop out. When the operator is in danger, he / she needs to find the cutting tool, which delays the escape time. Moreover, the tool is inconvenient to carry and easy to lose. The ceramic cutting disc 32 hidden in the housing 30 assists in emergency escape.

[0063] The auxiliary device also includes a round rod 33, a sliding button 34, and a contact rod 35. The round rod 33 is rotatably mounted on the surface of the housing 30. The sliding button 34 is threaded onto the circumferential surface of the round rod 33. The contact rod 35 is rotatably mounted on the surface of the sliding button 34. In the initial state, the position of the ceramic cutting disc 32 is restricted by the contact rod 35. A No. 4 torsion spring is provided between the contact rod 35 and the sliding button 34. The No. 4 torsion spring drives the contact rod 35 to reset. The round rod 33 is connected to the adjusting rod 21 by a belt drive. The circumferential surface of the round rod 33 is provided with a threaded groove.

[0064] It also includes a connecting frame 36, an abutment button 37, and a return spring 38. The connecting frame 36 is fixedly installed on the inner wall of the housing 30. The abutment button 37 is slidably installed on the inner wall of the connecting frame 36. The return spring 38 is disposed between the abutment button 37 and the connecting frame 36. The return spring 38 drives the abutment button 37 to reset. The top of the abutment button 37 is set as an arc surface. When the end of the slide groove contacts the arc surface of the abutment button 37, it blocks the movement of the ceramic cutting disc 32 and prevents the ceramic cutting disc 32 from being accidentally touched and falling out.

[0065] In this embodiment, during operation: The wearing layer 2 of the protective suit is made of breathable mesh fabric, which reduces friction between the outer layer of the protective suit and the human skin, preventing localized wear and thinning of the fabric due to human activity, and indirectly improving tear resistance durability. An additional high-performance fiber protective layer 3 is sewn onto the wearing layer 2 at locations with frequent movement and prone to external pulling. The protective suit is designed as a double-layer structure with an outermost release layer 5 and an inner protective layer 3, connected by a connecting buckle 16. The breaking threshold of the connecting buckle 16 is set to be greater than the pulling force of normal human activity but less than the dangerous tearing force. When the release layer 5 of the protective suit is hooked by a heavy object and generates a force exceeding... When the tearing force reaches the threshold, the connecting buckle 16 will automatically break, separating the outer and inner layers to prevent injury from being dragged by heavy objects. The inner protective layer 3 can still provide basic protection to prevent skin abrasions. The tension of the connecting buckle 16 can be adjusted by pulling the pull rope 110. Specifically, the pull rope 110 is pulled outward by the wheel rail 19, which drives the rack 18 to move along the slide rail 17. The movement of the rack 18 causes the gear 10 to rotate clockwise, which in turn drives the contact rod 112 to move. The clockwise rotation of the gear 10 drives the threaded cylinder 11 to rotate clockwise, which in turn causes the threaded rod 12 to rotate clockwise, thus moving the slide rail 112. The moving sleeve 14 drives the collar 15 to retract, and the movement of the collar 15 tightens the connecting buckle 16. The engagement between the turntable 13 and the collar 15 allows the release layer 5 to move freely over a wide range, distributing the concentrated tension across the entire contact surface of the connecting buckle 16 and preventing localized stress overload. When the pull rope 110 moves, the shift groove moves accordingly, and the limiting rod 111, set by the first spring, limits its insertion. Traditional layered structures have fixed connection strength, which can easily lead to two extreme problems: first, excessive locking force prevents the outer layer from detaching in time, causing the wearer to be dragged and injured; second, excessive locking force... The outer layer is small, and even slight pulling during daily operations can cause it to detach, losing its protective function. The adjustable fastener 16 can set the triggering force threshold for the outer layer to detach based on the worker's weight and the hazard level of the working environment. For example, heavier workers can choose a higher setting to avoid accidental detachment due to their own pulling force. When working in flammable or explosive environments, a lower setting can be selected to ensure that the outer layer can detach quickly in case of danger. When it is necessary to return to the initial state, the limit rod 111 can be pulled outward to release the limit groove. At this time, the first torsion spring resets, driving the wheel rail 19 to reset, which in turn drives the rack 18 to reset the gear 10.

[0066] Please see Figures 1-12 Based on the above embodiments, in another embodiment of the present invention, the antistatic protective clothing with tear-resistant function further includes a shrinking device and an auxiliary device.

[0067] In this embodiment, the tension of the elastic band inside the cuff 4 is adjusted by rotating the adjusting rod 21. Counterclockwise rotation tightens the band, while clockwise rotation loosens it. Simultaneously, the rotation of the adjusting rod 21 drives the ratchet 22 to rotate. When the ratchet 22 rotates counterclockwise, it contacts the non-sloping surface of the pawl 25. The second torsion spring ensures that the pawl 25 does not restrict the movement of the ratchet 22. When the ratchet 22 rotates clockwise, the sloping surface contact between the ratchet 22 and the pawl 25 restricts its rotation, preventing the adjusting rod 21 from rotating. Traditional Velcro is prone to loosening, and repeated fastening can cause fabric fiber wear. The self-locking structure of the ratchet 22 and pawl 25 stabilizes the tightening force of the cuff 4. When the elastic band needs to be loosened, the reset rod 26 is moved to the left, causing the reset rod 26 to engage with the control rod. When the lever 23 contacts, the pawl 25 rotates to the right and disengages from the ratchet 22. At this time, the ratchet 22 can be rotated clockwise normally. When the connecting buckle 16 is adjusted to the maximum position, the contact lever 112 moves to contact the brake lever 23, causing the brake lever 23 to drive the pawl 25 to rotate to the right, disengaging the pawl 25 from the ratchet 22. Traditional self-locking structures tend to tighten under strong pulling, causing the cuff 4 to be unable to loosen quickly during emergency escape, delaying escape time. When the connecting buckle 16 reaches the maximum locking position due to extreme pulling (about to trigger the outer layer to disengage), the cuff 4 tightening structure is in a completely relaxed state. Once the outer layer disengages, the wrist can be directly removed from the cuff 4 without additional unlocking operation, reducing the escape response time by more than 60% and significantly improving the survival probability in high-risk scenarios.

[0068] When workers encounter danger (such as when their protective clothing gets caught), they need to find additional cutting tools, delaying their escape time. Furthermore, these tools are inconvenient to carry and easily lost. To address this, a hidden ceramic cutting disc 32 is installed inside the housing 30 to assist in cutting, allowing workers to escape in an emergency. The ceramic cutting disc 32 is positioned within the storage rail 31 and compressed by a spring. When the adjusting rod 21 rotates, it drives a belt to rotate a round rod 33. The rotation of the round rod 33, with its threaded groove, causes a sliding button 34 to reciprocate. The movement of the sliding button 34 then moves the abutment rod 35. In the initial state, the position of the ceramic cutting disc 32 is... Restricted by the abutment rod 35, the movement of the abutment rod 35 gradually causes the No. 3 spring to move the ceramic cutting disc 32 to the outside of the housing 30. This causes the groove at the bottom of the ceramic cutting disc 32 to move closely against the arc surface of the abutment button 37. When the end of the groove contacts the arc surface of the abutment button 37, it blocks the movement of the ceramic cutting disc 32, preventing it from being accidentally knocked out. However, at this time, the gripping part of the ceramic cutting disc 32 is exposed outside the housing 30. At this point, the ceramic cutting disc 32 can be released from the restriction of the abutment rod 35 and the abutment button 37 by manual pulling, and emergency cutting can be performed.
