Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of helmets, and in particular to a winder, a cheek patch and a safety helmet with mandatory wearing specification. BACKGROUND

[0002] Safety helmets, as important personal protective equipment, are widely used in the work sites of the construction, power, mining and other industries. When the operating personnel are impacted or extruded by high-falling objects or hard objects, the impact force will be reduced by the safety helmet, and the damage to the human head will also be reduced or eliminated. Therefore, the operating personnel need to wear safety helmets in a specified manner to play the due protective role. Therefore, the operating personnel need to pull the chin strap out from below the helmet body and correctly tie it at the chin position, adjust the appropriate tightness, and ensure that the chin strap is in the correct position.

[0003] However, the phenomenon of not wearing safety helmets in a specified manner often occurs in work sites, such as not tying the chin strap or directly inserting the chin strap into the safety helmet, then directly buckling the safety helmet on the head, turning the chin strap to the front or rear edge of the helmet, and the operating personnel not adjusting the appropriate tightness. The above behaviors directly affect the protective effect of the safety helmet, causing the operating personnel to lose the due protection and bringing extremely high safety risks.

[0004] At present, management personnel will supervise the specified wearing of safety helmets through safety education and training and on-site supervision and inspection, but the effect is not good. Another form of electronic safety helmet monitors the wearing state through sensors and alarm devices, but the high cost, low reliability, complex maintenance and other problems limit its popularization in practical application. Although the conventional safety helmet is simple in structure and low in cost, it also lacks effective guidance and physical constraints on the wearing behavior. Therefore, there is an urgent need for a safety helmet that can provide mandatory constraints on the specified wearing behavior to effectively prevent the operating personnel from not tying the chin strap, incorrect chin strap position and other non-specified wearing behaviors.

[0017] As a preferred scheme of the cheek patch of the present application, wherein: a safety helmet; the fixed portion is arranged on both sides of the inside of the safety helmet and is fixed to the safety helmet.

[0018] The cheek patch of the present application has the beneficial effect of providing a simple modification of fixing the cheek patch to the double-ear position of the helmet or safety helmet, and through the hindering part, making the personnel feel uncomfortable on the face when the chin strap is not worn in a standard manner, and physically forcing the personnel to wear the chin strap in a standard manner, thereby avoiding facial discomfort and ensuring the safety protection effect of the helmet and safety helmet on the personnel.

[0019] Another object of the present application is to provide a safety helmet for preventing non-standard wearing of a chin strap, which aims to solve the problem of personal safety not being guaranteed due to the chin strap not being worn when the helmet or safety helmet is worn.

[0020] To solve the above technical problems, the present application provides the following technical solutions: a safety helmet for preventing non-standard wearing of a chin strap, comprising a cheek patch, and a safety helmet, wherein the fixing part is arranged on the inside of the safety helmet and fixed to the safety helmet.

[0021] As a preferred solution of the safety helmet for preventing non-standard wearing of a chin strap of the present application, the hat band of the safety helmet is aligned with the uneven structure.

[0022] The safety helmet for preventing non-standard wearing of a chin strap of the present application has the beneficial effect of providing a simple modification of fixing the cheek patch to the double-ear position of the helmet or safety helmet, and through the hindering part, making the personnel feel uncomfortable on the face when the chin strap is not worn in a standard manner, and physically forcing the personnel to wear the chin strap in a standard manner, thereby avoiding facial discomfort and ensuring the safety protection effect of the helmet and safety helmet on the personnel.

[0023] Another object of the present application is to provide a safety helmet for forcing standard wearing, which aims to solve the problems of the hat band of the conventional safety helmet not being easy to store, the chin strap not being tied or the chin strap being directly stuffed into the safety helmet, and then the safety helmet being directly buckled on the head, the chin strap being turned to the front or rear edge of the helmet, and the operating personnel not adjusting the appropriate tightness or not being convenient to adjust.

DETAILED DESCRIPTION

[0038] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0039] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, but the present application can also be implemented in other ways different from the description, and those skilled in the art can make similar generalizations without departing from the concept of the present application, therefore the present application is not limited to the specific embodiments disclosed below.

[0040] Secondly, "one embodiment" or "embodiment" referred to herein means that a specific feature, structure or characteristic can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor does it mean an embodiment that is separate or selectively excluded from other embodiments.

[0041] With reference to Figures 3-8 , the present embodiment provides a winding device, which comprises a winding unit 1, a shell 11, and a winding part 12 extending from the inside of the shell 11 to the outside; a locking unit 2 arranged on one side of the end face of the winding part 12; the winding part 12 comprises a rotating table 21 fixed to the outer end face thereof; the locking unit 2 comprises a plurality of locking columns 22 extending through the side wall of the rotating table 21, a reset spring 23 sleeved on the outer wall of the locking column 22, a limiting seat 24 arranged on the outer surface of the shell 11, a support table 25 fixed to the outer surface of the shell 11, a volute spring 26 fixed with the support table 25 and the rotating table 21, and a pressing rod 27 extending through the outer wall of the support table 25; The locking post 22 includes a guide portion 221 disposed at its end; one end of the return spring 23 contacts the inner wall of the rotary table 21, and the other end is located on one side of the guide portion 221; The limiting seat 24 includes a plurality of grooves 241 formed and arranged circumferentially on its inner wall; the locking pin 22 points to the grooves 241; The end of the pressure rod 27 points towards the guide part 221.

[0042] Furthermore, it also includes a cover plate 3, which is fixed to the opening of the housing 11.

[0043] Furthermore, the winding portion 12 includes an engagement groove 121 formed on its internal end face.

[0044] It should be noted that the housing 11 has a cavity that can accommodate the rope or strip wound in the same direction on the outer wall of the winding part 12. One end of the winding part 12 is fixed with a rotating platform 21, which penetrates the surface of the housing 11 and drives the winding part 12 to rotate at the point through which it penetrates the surface of the housing 11 through its own rotation.

[0045] As an alternative implementation, the rope or band can be fixed to the outer wall of the winding portion 12 by means of glue, knots, etc., and then both ends of the rope or band are simultaneously wound around the outer wall of the winding portion 12 in the same direction.

[0046] As an optional implementation, a through hole can be provided in the cover plate 3 at the position aligned with the end face of the winding section 12, so that the end face of the winding section 12 is exposed to the outside, making it convenient for personnel to adjust the number of rotations of the entire winding section 12 from the outside.

[0047] In a preferred embodiment, a cover plate 3 that closes the inner cavity is fixed at the opening of the cavity of the housing 11. The winding part 12 passes through the center of the end face of one end of the cover plate 3 and has a locking groove 121 along the axial direction for inserting a rope or belt. At this time, there is no need to use other methods to fix it additionally. The two ends of the rope or belt can be directly wound around the outer wall of the winding part 12 in the same direction.

[0048] In a preferred embodiment, the cover plate 3 is penetrated by the winding section 12, which allows personnel to adjust the number of rotations of the entire winding section 12 from the outside.

[0049] Preferably, one end face of the winding portion 12 is abutted by the through opening of the cover plate 3, and the other end face is abutted by the inner surface of the housing 11. Therefore, the winding portion 12 is fixed in the axial direction, and the diameter of the rotating table 21 penetrating the surface of the housing 11 is smaller than the diameter of the winding portion 12 abutted by the inner surface of the housing 11.

[0050] As a preferred embodiment, a bearing can be installed between the inner wall of the through opening on the surface of the housing 11 and the outer wall of the bottom of the rotary table 21 to reduce friction when the winding part 12 rotates.

[0051] Preferably, a limiting seat 24 is fixed to the outer surface of the housing 11, the limiting seat 24 surrounds the rotating platform 21, and a plurality of circumferentially arrayed grooves 241 are formed on the inner wall of the limiting seat 24. The rotating platform 21 is provided with at least two locking pins 22 penetrating its side wall. In this embodiment, two locking pins 22 are used and are distributed circumferentially along the rotating platform 21. In addition, the locking pins 22 are aligned with the grooves 241.

[0052] The axial cross-sectional shape of the end of the locking pin 22 aligns with the shape of the groove 241, while the other end is provided with a guide portion 221. In this embodiment, the axial cross-sectional shape of the end of the locking pin 22 and the groove 241 are arc-shaped.

[0053] As an alternative implementation, the guide portion 221 on the locking post 22 has a regular shape such as a hemispherical shape, a frustum shape, a trapezoidal shape, or a cone shape, and the cross-sectional area gradually decreases from the end face of the locking post 22 to the end of the guide portion 221.

[0054] In a preferred embodiment, the guide portion 221 is shaped like a round pot lid and its maximum outer diameter is larger than that of the locking pin 22.

[0055] Preferably, a return spring 23 is sleeved on the outer wall of the locking post 22. One end of the return spring 23 contacts the inner wall of the rotating table 21, and the other end is located on one side of the guide part 221. Specifically, when the maximum outer diameter of the guide part 221 or the diameter of its circumscribed circle is less than or equal to the diameter of the locking post 22, the other end of the return spring 23 is fixed on the outer wall of the locking post 22; otherwise, it abuts against one side of the guide part 221.

[0056] It should be noted that when the locking pin 22 is in a state of natural absence of external force, under the action of the return spring 23, the guide parts 221 will be in contact. At this time, the other end of the locking pin 22 is away from the groove 241, so the winding part 12 can rotate normally. However, when the guide parts 221 are subjected to external force, the locking pin 22 will push against the groove 241, and the winding part 12 will be locked and unable to rotate.

[0057] Preferably, a support platform 25 is also fixed to the outer surface of the housing 11. The support platform 25 also has a cavity, which serves to cover the limiting seat 24 and provide a fixing point for the outer end of the spiral spring 26. The inner end of the spiral spring 26 is fixed to the outer wall of the rotating platform 21. At this time, the rotating winding part 12 will be subjected to the force of the spiral spring 26.

[0058] Preferably, the pressure rod 27 extends from the center of the support platform 25 to the position adjacent to the guide part 221. When a person actively presses the pressure rod 27, the locking pin 22 can be pushed into the groove 241. When the pressure rod 27 is pulled out, the locking pin 22 is reset.

[0059] In a preferred embodiment, a limiting ring is provided on the outer wall of the pressure rod 27, and the limiting ring is located inside the support platform 25 to prevent the pressure rod 27 from dislodging.

[0060] As a preferred embodiment, the pressure bar 27 can be reduced in weight by hollowing out its interior or by using lightweight materials, so that the pressure bar 27 can be placed on the side edge of the guide portion 221 without being affected by external factors and actively press against each locking post 22.

[0061] It should be noted that this refers to rope-like or strip-like flexible objects, including but not limited to data cables, strip data cables, wires, and ropes or strips of various materials.

[0062] The entire process of using the winding device is as follows: First, overcome the resistance of the spiral spring 26 and rotate the winding part 12 to a suitable force. Then, connect the ends of the rope or belt and place it inside the locking groove 121 and wind it around the outer wall of the winding part 12 in the same direction. At this time, the rope or belt needs to pass through both sides of the housing 11 or through the surface of the cover plate 3. Then, loosen the rope or belt. Under the action of the spiral spring 26, the rope or belt will tighten.

[0063] When the rope or belt is pulled, it will be subjected to the force of the spiral spring 26. At this time, the pressure bar 27 is pressed, and the lower end of the pressure bar 27 will squeeze the guide part 221 and push each locking pin 22 into the groove 241. Then the guide part 221 will press against the body of the pressure bar 27. At this time, the pressure bar 27 is pressed and remains in a relatively stable state, making it difficult to be affected by external factors and disengage from the guide part 221. At the same time, the winding part 12 will be locked.

[0064] When it is necessary to wind up the rope or belt, pull out the pressure bar 27. At this time, the pressure bar 27 returns to its original position, and under the action of the spiral spring 26, the winding part 12 is forced to rotate to wind up the rope or belt. At this time, the pressure bar 27 is lightweight and is placed lightly on the outer edge of each guide part 221, and will not easily insert between the guide parts 221.

[0065] In summary, this application ensures that the rope or belt can be effectively wound up by using a locking unit to forcibly lock the wound rope or belt, so that the winding device can ensure that the rope or belt is not pulled out at any degree of winding up, thereby increasing the effective locking effect of the rope or belt at any degree of winding up.

[0066] Reference Figures 1-8 This embodiment further provides a safety helmet with a retractable hood drawstring, including a retractable mechanism for automatically retracting the drawstring or strap; Safety helmet 4; the winding mechanism is fixed to the top inside the safety helmet 4.

[0067] It should be noted that the winding mechanism uses a conventional winding device for winding and storing flexible objects such as ropes, lines, and strips, such as a winding mechanism for winding data cables, strip data cables, and wires. In this embodiment, the winding medium can be directly replaced by braided rope or braided strip by disassembly, and the disassembly method is also a conventional technology.

[0068] The winding mechanism can be fixed to the top of the helmet 4 by making a hole in the top and using cable ties, wires, etc. Alternatively, it can be directly fixed to the inside of the helmet 4 by using hot melt adhesive or casting adhesive. Or, the helmet 4 and the winding mechanism can be fixed together by making holes in them and using simple connectors such as rods or brackets with bolts or screws.

[0069] When using it, you can directly pull the braided rope or braided strip from the existing winder and put it on your chin. The winder's own winding force will fix the braided rope or braided strip on your chin.

[0070] It should be noted that the type of spiral spring inside the existing winder can be selected and replaced.

[0071] As a preferred embodiment, the winding mechanism includes, The winding unit 1 includes a housing 11 and a winding portion 12 extending from the inside of the housing 11 to the outside. Locking unit 2 is disposed on one side of the end face outside the winding part 12; the winding part 12 includes a rotating platform 21 fixed to its outer end face; the locking unit 2 includes a plurality of locking pins 22 passing through the side wall of the rotating platform 21, a return spring 23 sleeved on the outer wall of the locking pins 22, a limiting seat 24 disposed on the outer surface of the housing 11, a support platform 25 fixed to the outer surface of the housing 11, a spiral spring 26 fixed to both the support platform 25 and the rotating platform 21, and a pressure rod 27 passing through the outer wall of the support platform 25. The locking post 22 includes a guide portion 221 disposed at its end; one end of the return spring 23 contacts the inner wall of the rotary table 21, and the other end is located on one side of the guide portion 221; The limiting seat 24 includes a plurality of grooves 241 formed and arranged circumferentially on its inner wall; the locking pin 22 points to the grooves 241; The end of the pressure rod 27 points towards the guide part 221; The housing 11 includes a pair of transverse slots 111 formed in its sidewall; the pressure bar 27 extends through the helmet 4 to the outside; The braided tape 5 is wrapped around the outer wall of the winding part 12 and fixed to the winding part 12, and is twisted through both sides of the housing 11.

[0072] It should be noted that, as a more preferred method, the winding mechanism can be implemented using the winding device described in this application. The structure, installation and principle are the same as those of the winding device described above in this application, and will not be repeated here. However, the winding device in this application uses braided tape 5 as the winding medium. Compared with braided rope, it can reduce and distribute the pressure on the chin, providing good comfort. In addition, in order to facilitate the winding of the braided tape 5, the braided tape 5 is placed longitudinally during winding. At this time, the braided tape 5 needs to be twisted inside the housing 11 and then extend laterally from both sides of the housing 11 to ensure the smoothness of the braided tape 5 as the chin strap during winding.

[0073] Furthermore, in this preferred embodiment, two pairs of symmetrically distributed long screws are used to penetrate the safety helmet 4 and are directly threaded to the housing 11.

[0074] As a preferred embodiment, a through hole is provided at the top of the safety helmet 4 for the pressure bar 27 to pass through. In order to ensure that the pressure bar 27 can extend out of the safety helmet 4, a lightweight extension bar can also be added to facilitate the operation of the pressure bar 27 by personnel.

[0075] As a preferred embodiment, an extension plate of a certain length is fixed on both sides of the housing 11, that is, below the point where the braided strap 5 passes through, to avoid unnecessary pressure on the head of the personnel by the braided strap 5.

[0076] In actual use, both ends of the braided strap 5 can be placed between the outer shell of the safety helmet 4 and the headband. After the braided strap 5 is rolled up, it is restricted by the headband and placed horizontally at the lower edge of the headband, which makes it easy for people to hook it and also prevents people from ignoring the braided strap 5 and directly fastening the safety helmet 4 to their head.

[0077] In summary, this application also provides a simple modification that allows the safety helmet to have a retractable chin strap or chin band, ensuring a neat and tidy appearance when the helmet is placed on a flat surface and preventing the chin strap or chin band from becoming tangled. Furthermore, the chin strap or chin band can be easily pulled out with one hand, allowing for convenient helmet wearing without the need for two hands, thus eliminating the possibility of workers improperly fastening the chin band for convenience. Simultaneously, when the worker pulls the chin band out from under the helmet and fastens it at the chin, it facilitates adjusting the tightness appropriately. Finally, because the chin strap or chin band is rolled up and placed horizontally inside the helmet before wearing, it prevents workers from ignoring the chin strap and chin band and directly fastening the helmet to their head, forcing workers to pull out the chin strap or chin band before putting on the helmet, thus continuously reinforcing the habit of workers properly wearing the chin strap or chin band.

[0078] Reference Figures 9-10 Another objective of this embodiment is to provide a cheek patch, including a fixing part 6 and an obstruction part 7 connected to the fixing part 6.

[0079] Furthermore, the obstruction 7 includes an uneven structure 71 disposed on its surface.

[0080] It should be noted that the cheek patch consists of two parts, which can be molded as one piece or the two parts can be fixed together. The fixing part 6 is mainly used for fixing and connecting to the two sides of the inner wall of the helmet or visor, the two sides of the headband or the two sides of the liner. It is usually flat in shape, but can also be any shape that serves only as a fixing medium.

[0081] The obstruction part 7 is located at the ear and has a certain length. It is usually flat and has a certain length. It can also be fixedly connected to the ear by a rod or strip. The connection method is not limited. However, on the side of the obstruction part 7 facing the face, there is an uneven structure 71 pointing towards the face. The uneven structure 71 can be a raised shape, a groove shape, a hollow shape, or a combination of any of the above forms, such as distributed protrusions, raised strips, arbitrarily distributed grooves and slots, arbitrarily distributed hollows, burrs, rough surfaces, etc., which can cause discomfort on the face.

[0082] Preferably, the cheek patch needs to be used with a safety helmet or a regular helmet, both of which come with a chin strap. Only when the chin strap is placed between the face and the uneven structure 71 can the discomfort caused by the uneven structure 71 be offset by the blocking effect of the chin strap on the face.

[0083] In practical use, the cheek patches need to be symmetrically fixed on both sides of the ears of the helmet or visor, that is, where the chin strap is located, so that the uneven structure 71 is aligned with the chin strap. The installation method is simple and quick.

[0084] In summary, this application provides a simple modification that fixes cheek patches to the ear positions of a helmet or safety helmet. By obstructing the chin strap, it prevents discomfort to the person's face when the chin strap is not worn properly. Physically, it forces the person to wear the chin strap properly, thereby avoiding facial discomfort and ensuring the protective effect of the helmet and safety helmet on the person's safety.

[0085] Reference Figures 1-2 ,and Figures 9-10 This embodiment provides a safety helmet to prevent improper wearing of the chin strap, including cheek patches; and, Safety helmet 4; fixing part 6 is provided on both sides inside the safety helmet 4 and fixed to the safety helmet 4.

[0086] Furthermore, the chin strap of the safety helmet 4 is aligned with the uneven structure 71.

[0087] It should be noted that the cheek patch consists of two parts, which can be molded as one piece or the two parts can be fixed together. The fixing part 6 is mainly used to fix and connect to the two sides of the inner wall of the helmet 4, the two sides of the headband, or the two sides of the inner liner. It is usually flat in shape, but can also be any shape that serves only as a fixing medium.

[0088] The obstruction part 7 is located at the ear and has a certain length. It is usually flat and has a certain length. It can also be fixedly connected to the ear by a rod or strip. The connection method is not limited. However, on the side of the obstruction part 7 facing the face, there is an uneven structure 71 pointing towards the face. The uneven structure 71 can be a raised shape, a groove shape, a hollow shape, or a combination of any of the above forms, such as distributed protrusions, raised strips, arbitrarily distributed grooves and slots, arbitrarily distributed hollows, burrs, rough surfaces, etc., which can cause discomfort on the face.

[0089] Preferably, the cheek patch needs to be used with the helmet 4, which has a built-in chin strap. Only when the chin strap is placed between the face and the uneven structure 71 can the discomfort caused by the uneven structure 71 be offset by the blocking effect of the chin strap on the face.

[0090] In actual use, the cheek patches need to be symmetrically fixed on both sides of the ears of the helmet 4 or helmet, that is, the position of the chin strap, so that the uneven structure 71 is aligned with the chin strap. The installation method is simple and quick.

[0091] In summary, this application provides a simple modification that fixes cheek patches to the ear positions of a helmet or safety helmet. By obstructing the chin strap, it prevents discomfort to the person's face when the chin strap is not worn properly. Physically, it forces the person to wear the chin strap properly, thereby avoiding facial discomfort and ensuring the protective effect of the helmet and safety helmet on the person's safety.

[0092] Reference Figures 1-10 This embodiment provides a mandatory safety helmet, including a helmet with a retractable chin strap and cheek patches; and, The braided tape 5 is wrapped around the outer wall of the winding part 12 and fixed to the winding part 12, and is twisted through both sides of the housing 11; The woven strip 5 is aligned with the uneven structure 71.

[0093] It should be noted that the construction, installation and principle of the retractable helmet and cheek patch have been described in detail in the foregoing process of this application, and will not be repeated here. In addition to the above, it should be noted that when the helmet 4 adopts the retractable structure in the prior art, the braided rope or braided tape can isolate the obstruction part 7 in the cheek patch.

[0094] When the helmet 4 uses the retractor of this application, preferably the woven strap 5, the isolation effect on the obstruction part 7 and the wearing comfort are better.

[0095] In summary, this application provides a simple modification that allows the safety helmet to have a retractable chin strap or chin band. This ensures a neat and tidy appearance when the helmet is placed on a flat surface, preventing the chin strap or chin band from becoming tangled. Furthermore, the chin strap or chin band can be easily pulled out with one hand, allowing for convenient helmet wearing without the need for two hands, thus eliminating the possibility of workers improperly fastening the chin band for convenience. Simultaneously, when the worker pulls the chin band out from under the helmet and fastens it at the chin, it is easy to adjust the tightness appropriately. Since the chin strap or chin band is in a rolled-up state before wearing, it can be placed horizontally... Inside the helmet, there are features that prevent workers from ignoring the chin strap or chin band and directly fastening the helmet to their head. This forces workers to pull out the chin strap or chin band before putting on the helmet, continuously reinforcing the habit of wearing the chin strap or chin band correctly. In addition, by fixing the cheek patches to the ears of the helmet or safety helmet, the system prevents discomfort to the face caused by improper chin strap wearing, such as flipping the chin band to the front or back edge of the helmet. This physical mechanism forces workers to wear the chin strap correctly, avoiding facial discomfort and ensuring the protective effect of the helmet and safety helmet on personnel safety.
