Description

Technical Field

[0001] This utility model relates to the field of protective clothing technology, specifically to protective clothing with quick-release function. Background Technology

[0002] Protective clothing includes fire-fighting protective clothing, industrial protective clothing, medical protective clothing, military protective clothing, and protective clothing for special populations. Flame-retardant clothing is one of the most widely used types of personal protective equipment for fire fighting. The protective principle of flame-retardant clothing mainly involves shielding through heat insulation, reflection, absorption, and carbonization, protecting workers from open flames or heat sources.

[0003] The placket refers to the opening, slit, or partition in the front center of a garment. Protective clothing plackets are fitted with standard zippers. Zippers are common fasteners used in clothing. A zipper includes a left zipper strap and a right zipper strap. The zipper pull engages the teeth of both straps, merging them together. An upper stop assembly is located at the top of the zipper, and a lower stop assembly is located at the bottom. Both components prevent the zipper pull from disengaging from the zipper strap.

[0004] When using ordinary zippers on protective suits, the zipper pull is moved upwards from its initial position along the left and right zipper straps to close them. To unzip the suit, the zipper pull must be pulled downwards back to its initial position. However, this method of zipper removal is cumbersome in emergency situations, making it difficult to quickly remove the suit. For example, workers emerging from a fire must remove their protective suit as quickly as possible to avoid skin damage from sparks if it catches fire. Similarly, in chemical production environments, workers must remove their protective suits as quickly as possible to prevent skin damage from corrosive liquids. Therefore, there is an urgent need in this technical field for a protective suit with a quick-release function. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a protective suit with a quick-release function.

[0006] The technical solution adopted in this utility model is: a protective suit with quick-release function, comprising:

[0007] Protective suit body, quick-release zipper, protective veil, and snap fasteners;

[0008] The protective suit body has a quick-release zipper installed on its placket. One side of the protective cover strip is fixedly connected to one side of the placket, and the other side of the protective cover strip is connected to the other side of the placket via a snap fastener. The protective cover strip covers the quick-release zipper.

[0009] The quick-release zipper includes a left zipper tape, a right zipper tape, an upper stop assembly, a lower stop assembly, and a zipper pull. The upper stop assembly includes a left elastic block and a right elastic block arranged side by side. The left elastic block is fixedly connected to the top of the left zipper tape, and the right elastic block is fixedly connected to the top of the right zipper tape. A smooth chain block is also fixedly connected above the right elastic block on the right zipper tape, and a limit fastener is also fixedly connected above the smooth chain block on the right zipper tape. The left zipper tape is a flat tape above the left elastic block. The lower stop assembly includes a left insert bar and a right insert bar arranged side by side. The upper end of the insert bar is fixedly connected to the bottom of the left zipper belt, and the upper end of the right box bar is fixedly connected to the bottom of the right zipper belt. A box block is fixedly provided at the lower end of the right box bar. The box block has an insertion hole, and the left insert bar can be inserted into the insertion hole. The zipper head can lock the chain teeth of the left and right zipper belts. When the zipper head is subjected to a quick-release force, the zipper head can pass through the left and right elastic blocks. When the zipper head moves to the smooth chain block, the flat belt can disengage from the zipper head. The limiting fastener can prevent the zipper head from coming off the right zipper belt.

[0010] Furthermore, the left elastic block is L-shaped, and the shape of the right elastic block is symmetrical to that of the left elastic block.

[0011] Furthermore, the snap fastener device includes a first male buckle, a first female buckle, a second male buckle, and a second female buckle. The first male buckle is fixedly disposed on the upper inner surface of the protective strip, the first female buckle is fixedly disposed on the outer surface of the collar of the protective suit body, the second male buckle is fixedly disposed on the lower inner surface of the protective strip, and the second female buckle is fixedly disposed on the outer surface of the waist of the protective suit body.

[0012] Furthermore, the pull head includes an upper cover plate and a lower cover plate. A support column is fixedly disposed between the upper cover plate and the lower cover plate. A toothed groove is provided between the upper cover plate and the lower cover plate. The toothed groove is located below the support column. The left and right sides of the support column are two chain tooth inlets, and the lower end of the toothed groove is a chain tooth outlet. The left and right sides of the upper cover plate and the lower cover plate are provided with upper flanges and lower flanges. A side groove is formed between the upper flanges and the lower flanges. The thickness of the smooth chain block and the thickness of the chain teeth are both greater than the side groove, and the thickness of the flat belt is less than the side groove.

[0013] Furthermore, both the left elastic block and the right elastic block are rubber blocks.

[0014] Furthermore, the protective suit body is a flame-retardant suit body.

[0015] Compared with the prior art, the beneficial effects or advantages of this utility model are as follows: The left and right elastic blocks of the upper stop component of the quick-release zipper play a role in initially preventing the zipper head from moving. When the zipper head encounters the left and right elastic blocks, it locks the teeth of the left and right zipper tapes, thus closing the left and right zipper tapes. In case of an emergency requiring the protective clothing to be removed quickly, the worker pulls the zipper head upwards. The zipper head moves to the position of the smooth chain block after passing the left and right elastic blocks. At this time, the flat belt disengages from the zipper head, so the worker can tear open the left and right zipper tapes by hand to quickly remove the zipper, without having to pull the zipper head down to the initial position as in the prior art. The protective cover prevents the quick-release zipper from being exposed, protects the quick-release zipper from damage, and prevents accidental operation of the quick-release zipper.

[0029] This utility model embodiment provides a protective suit with quick-release function. The overall technical concept is as follows:

[0030] A uniquely structured quick-release zipper is installed on the placket of the protective suit. The upper stop component of the quick-release zipper has a unique structure, while the lower stop component is the same as that of a regular zipper. When the worker puts on the protective suit, the zipper head is located at the bottom of the right zipper tape and in contact with the box block, i.e., the zipper head is in its initial position. Then, the left insert bar is passed through the zipper head and inserted into the insertion hole of the box block. When the zipper head is pulled upward, it locks the teeth of the left and right zipper tapes. The zipper head stops pulling when it encounters the left and right elastic blocks of the upper stop component. The left and right elastic blocks initially prevent the zipper head from moving, and at this time, the left and right zipper tapes are closed. The worker then covers the quick-release zipper with a protective strip and fixes the protective strip to the protective suit body with a snap fastener. At this time, the quick-release zipper is hidden by the protective strip, preventing external objects from touching the quick-release zipper and causing accidental operation.

[0031] When an emergency requires the protective suit to be removed quickly, the worker unfastens the snap fastener, then grasps the zipper pull and applies pressure by pulling upwards. This causes the zipper pull to compress the left and right elastic blocks, deforming them. The deformed blocks then pass through the zipper pull and reach the smooth chain block. The smooth chain block of the right zipper belt slides into contact with the zipper pull, while the flat strap of the left zipper belt disengages. At this point, the worker can tear open the left and right zipper belts by hand, pull the left insert out of the insertion hole in the box block, quickly unzip the zipper, and finally remove the protective suit. This eliminates the need to pull the zipper pull back to its initial position as in the previous method.

[0032] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0033] See Figures 1 to 11 The preferred embodiment of this utility model.

[0034] A protective suit with quick-release function includes:

[0035] 1. Protective suit body; 2. Quick-release zipper; 3. Protective veil; 4. Fastener device;

[0036] The protective suit body 1 has a quick-release zipper 2 installed on its placket. One side of the protective cover strip 3 is fixedly connected to one side of the placket, and the other side of the protective cover strip 3 is connected to the other side of the placket through a snap fastener assembly. The protective cover strip 3 covers the quick-release zipper 2.

[0037] The quick-release zipper 2 includes a left zipper tape 21, a right zipper tape 22, an upper stop assembly, a lower stop assembly, and a zipper pull 23. The upper stop assembly includes a left elastic block 211 and a right elastic block 221 arranged side by side. The left elastic block 211 is fixedly connected to the top of the left zipper tape 21, and the right elastic block 221 is fixedly connected to the top of the right zipper tape 22. A smooth chain block 222 is also fixedly connected above the right elastic block 221 on the right zipper tape 22. A limit fastener 223 is also fixedly connected above the smooth chain block 222 on the right zipper tape 22. A flat tape 212 is located above the left elastic block 211 on the left zipper tape 21. The lower stop assembly includes a left insert bar 213 and a right box bar 224 arranged side by side. The upper end of the bar 213 is fixedly connected to the bottom of the left zipper belt 21, and the upper end of the right box bar 224 is fixedly connected to the bottom of the right zipper belt 22. A box block 225 is fixedly provided at the lower end of the right box bar 224. The box block 225 has an insertion hole, and the left insertion bar 213 can be inserted into the insertion hole. The zipper head 23 can lock the chain teeth of the left zipper belt 21 and the right zipper belt 22. When the zipper head 23 is subjected to a quick-release force, the zipper head 23 can pass through the left elastic block 211 and the right elastic block 221. When the zipper head 23 moves to the smooth chain block 222, the flat belt 212 can disengage from the zipper head 23. The limiting fastener 223 can prevent the zipper head 23 from coming off the right zipper belt 22.

[0038] The beneficial effects or advantages of this utility model are as follows: The left elastic block 211 and right elastic block 221 of the upper stop component of the quick-release zipper 2 play a role in initially preventing the zipper head 23 from moving. When the zipper head 23 encounters the left elastic block 211 and right elastic block 221, it locks the chain teeth of the left zipper belt 21 and right zipper belt 22, thereby closing the left zipper belt 21 and right zipper belt 22. When an emergency occurs and the protective clothing body 1 needs to be removed as soon as possible, the staff will pull the zipper head 23 upwards. The zipper head 23 moves to the position of the smooth chain block 222 after passing the left elastic block 211 and right elastic block 221. At this time, the flat belt 212 disengages from the zipper head 23, so the staff can tear open the left zipper belt 21 and right zipper belt 22 by hand and quickly remove the zipper without having to pull the zipper head 23 downwards back to the initial position as in the prior art. The protective cover strip 3 plays a role in preventing the quick-release zipper 2 from being exposed, protecting the quick-release zipper 2 from damage and preventing accidental operation of the quick-release zipper 2.

[0039] The upper stop component of the quick-release zipper 2 is a unique structure of this utility model, while the lower stop component of the quick-release zipper 2 belongs to the lower stop component of a common zipper in the prior art. When the zipper head 23 is in the position of the right box bar 224 and box block 225 of the lower stop component, that is, the zipper head 23 is in the initial position; the left insertion bar 213 of the lower stop component is passed through the zipper head 23 and inserted into the insertion hole of the box block 225, and then the zipper head 23 is pulled upward, the zipper head 23 locks the chain teeth of the left zipper tape 21 and the right zipper tape 22. The zipper head 23 stops moving when it encounters the left elastic block 211 and the right elastic block 221 of the upper stop component, at which point the left zipper tape 21 and the right zipper tape 22 are closed; when it is necessary to quickly remove the protective clothing, the worker's hand... Apply an acceleration and unloading force to the zipper pull 23, that is, pull the zipper pull 23 upward forcefully. The zipper pull 23 passes through the left elastic block 211 and the right elastic block 221. The deformed left elastic block 211 and the right elastic block 221 pass through the inside of the zipper pull 23. When the zipper pull 23 reaches the smooth chain block 222 of the right zipper belt 22, the flat belt 212 of the left zipper belt 21 disengages from the zipper pull 23. The worker then tears the left zipper belt 21 and the right zipper belt 22 apart by hand. The left insert 213 is pulled out from the insertion hole of the box block 225, the zipper is quickly unloaded, and finally the protective clothing is removed.

[0040] When the protective strip 3 is connected to the protective suit body 1 via the snap fastener 4, the placket is also secured by the protective strip 3 to prevent it from opening. The snap fastener is a type of button that uses an S-shaped spring for connection. One part, called the female button, has a protruding dot in the center, while the other part, called the female button, has a recessed hole in the center and two parallel springs on the side. When the dot is pressed into the hole of the female button, it is clamped by the spring, generating an opening and closing force to secure the garment.

[0041] In this embodiment, there are two smooth chain blocks 222. The two smooth chain blocks 222 help the right zipper tape 22 to bend accordingly, so that the smooth chain blocks 222 of the right zipper tape 22 can pass smoothly through the zipper head 23. When both smooth chain blocks 222 enter the zipper head 23, the flat tape 212 in the opposite position also enters the zipper head 23, and then the flat tape 212 of the left zipper tape 21 disengages from the zipper head 23.

[0042] Furthermore, the left elastic block 211 is L-shaped, and the shape of the right elastic block 221 is symmetrical to that of the left elastic block 211.

[0043] This is a preferred structural product of this utility model. Combined with... Figure 4 and Figure 7 The bottom of the L-shaped elastic block is shaped like a horizontal bar, which initially blocks the pull head 23; combined with Figure 8 and Figure 9 When the pull head 23 is subjected to an acceleration unloading force, the pull head 23 compresses the crossbar shape, causing the crossbar shape to elastically deform and move closer to the vertical shape of the L-shaped elastic block. After the elastic block passes through the interior of the pull head 23, the crossbar shape returns to its original shape. For example, the acceleration unloading force and the elastic force of the L-shaped elastic block are matched according to the daily capabilities of firefighters.

[0044] Furthermore, the snap fastener 4 includes a first snap fastener 41, a first female snap fastener 42, a second snap fastener, and a second female snap fastener. The first snap fastener 41 is fixedly disposed on the upper inner surface of the protective strip 3, the first female snap fastener 42 is fixedly disposed on the outer surface of the collar of the protective suit body 1, the second snap fastener is fixedly disposed on the lower inner surface of the protective strip 3, and the second female snap fastener is fixedly disposed on the outer surface of the waist of the protective suit body 1.

[0045] The beneficial effects of this technical solution are as follows: There are two fastener devices 4, which are set at the top and bottom respectively. The first male fastener 41 and the first female fastener 42 are used to fix the upper end of the protective strip 3, and the second male fastener and the second female fastener are used to fix the lower end of the protective strip 3, which helps the protective strip 3 to cover the quick-release zipper 2 more smoothly.

[0046] Several sub-buttons are set between the first sub-button 41 and the second sub-button as needed, and correspondingly, several female buttons are set between the first female button 42 and the second female button as needed.

[0047] Furthermore, the pull head 23 includes an upper cover plate 231 and a lower cover plate 232. A support column 233 is fixedly disposed between the upper cover plate 231 and the lower cover plate 232. A toothed groove 234 is provided between the upper cover plate 231 and the lower cover plate 232. The toothed groove 234 is located below the support column 233. Two chain tooth inlets 235 are located on the left and right sides of the support column 233. The lower end of the toothed groove 234 is a chain tooth outlet 236. An upper flange 237 and a lower flange 238 are provided on the left and right sides of the upper cover plate 231 and the lower cover plate 232. A side groove 239 is formed between the upper flange 237 and the lower flange 238. The thickness of the smooth chain block 222 and the thickness of the chain teeth are both greater than the side groove 239. The thickness of the flat belt 212 is less than the side groove 239.

[0048] This is a preferred structure of the present invention. The smooth chain block 222 and chain teeth are slidably connected to the tooth groove 234, but neither the smooth chain block 222 nor the chain teeth can disengage from the side groove 239. The flat belt 212 can disengage from the side groove 239. The pull head 23 has a pull tab 2310 for easy manual operation.

[0049] Furthermore, both the left elastic block 211 and the right elastic block 221 are rubber blocks.

[0050] The quick-release force applied by the operator to the slider 23 causes the support 233 of the slider 23 to compress the left elastic block 211 and the right elastic block 212, causing deformation of the rubber blocks. This means the quick-release force overcomes the resistance of the rubber blocks, allowing the slider 23 to pass through the left elastic block 211 and the right elastic block 221. After the left elastic block 211 and the right elastic block 221 exit from the chain tooth outlet of the slider 23, they return to their original shape due to elasticity.

[0051] Furthermore, the protective suit body 1 is a flame-retardant suit body.

[0052] Flame-retardant clothing is a one-piece structure consisting of a top and trousers; the placket extends from the collar to the waist, and even to the pelvic area.

[0053] This utility model of a protective suit with quick-release function is suitable for emergency situations. When it is necessary to remove the protective suit, first unfasten the interlocking device, flip up the protective cover strip 3, and the worker forcefully pulls the zipper head 23 upward through the left elastic block 211 and right elastic block 221 of the upper stop component. The left zipper strap 21 will then disengage from the zipper head 23 through the flat strap 212, allowing the worker to quickly unzip the zipper, open the placket of the protective suit body 1, and finally remove the protective suit. The operation is convenient.
