Description
Technical Field
The utility model belongs to the technical field of the industrial mask respirator, concretely relates to industrial mask just picks and easy knot mechanism that resets.
Background
The dustproof mask aims to prevent or reduce dust in the air from entering human respiratory organs, thereby protecting life safety of individual protective articles; the materials of the medical instrument are mostly composed of various plastics, silicon rubber, silica gel and the like. Dustproof mask commonly is applied to industrial and mining, exploitation, metallurgy, field environment such as polishing, need ensure in the use that the position of wearing at every turn is correct, can reach and not reveal the effect, still must insist on continuously wearing in the operation of connecing the dirt. If uncomfortable, such as too tight a headband, too high resistance, etc., is felt during use, unauthorized changes to the headband length, or loosening of the nasal splint, etc., are not allowed. Therefore, a good respirator should not only fit the user, but also have a degree of comfort and durability in that the increase in breathing resistance is slow, the mask is light, the headgear is not easily collapsible, the mask is not easily collapsible, the nose clip or headgear is securely fixed, and the like.
The half mask is used in dust collecting environments of high-concentration dust such as industrial and mining, grinding and metallurgy, the safety helmet is required to be worn, and the safety helmet is not allowed to be taken off in the operation process, so that the safety of the head is protected. However, in actual use, the operator needs not only communication but also necessary actions such as rest and drinking water. At present, the half face mask which is tightly attached can make the sound deep, stuffy and inaudible; moreover, workers cannot take off the half mask on site immediately, and need to go to a designated safety place to take off the safety helmet and the half mask, so that the working efficiency is greatly reduced.
When the existing half mask on the market is used, a worker can forcibly pull the elastic band and the plastic mouth-nose cover cap in the using process, so that the mask body of the half mask can move, and the speaking is convenient. However, in the design of the mask, the fact that the user can move the mask body is not considered at the beginning, so that the mask is very inconvenient to use, the mask body is pulled back and forth, the reset mask body is not firmly attached to the face, and the mask cannot bring sufficient safety protection to the user who wears the mask.
SUMMERY OF THE UTILITY MODEL
The dustproof half face guard of current industry is taken inconvenience temporarily in the industrial and mining environment, and the lock easily takes place to shift to and the face guard wears to dismantle has the problem of conflict with other safety protective equipment such as safety helmet, and the operation convenience of using is not adapted. This reality is novel to provide an easy knot mechanism that just takes and reset of industrial mask, changes the lock position of the half face guard cover body through this a locking mechanism of easy knot, relaxs through easy knot and increases and lift elasticity area length to relax half face guard by face, leak the person's of wearing the oral cavity and the nose, and need not dismantle the fastener behind bandeau and the neck. After the action such as the person of wearing finishes drinking water or uses the platform, if will detain half face utensil back, then will easily detain the straining, this process has obvious damping and feels, and the half face guard of accomplishing the back fastening resumes the state of laminating originally, and need not to adjust the wearing state before other parts elasticity can resume, provides and takes the simple operation nature and guaranteed that relapse the lock does not shift. The specific technical scheme is as follows:
an easy-buckling mechanism for conveniently picking and resetting an industrial mask is characterized in that the whole easy-buckling mechanism is a U-shaped easy-buckling piece and is arranged at a mouth and nose cover of a half mask, and connecting guide pillars 1 are arranged on the inner sides of two ends of a U-shaped arm of the easy-buckling mechanism and are used for being connected with the mouth and nose cover; the front end of the easy-buckling mechanism is a plane, a left elastic band positioning hole 2 and a right elastic band positioning hole 2 are formed in the plane and used for penetrating the elastic bands, and the elastic bands are used for positioning the easy-buckling mechanism and are not deviated; the bottom surface of the U-shaped arm of the easy-buckling mechanism is provided with a reinforcing rib 4 for reinforcing the strength of the U-shaped arm; the reinforcing ribs 4 are positioned at two end parts of the U-shaped arm and are provided with gear parts 3 for switching movable gears of the easy-buckling mechanism.
In the above technical solution, the gear portion 3 is V-shaped.
Among the above-mentioned technical scheme, the switching state of gear portion 3 divide into lock and two states of unblock, realizes easily detaining laminating and the relaxation of mechanism.
Among the above-mentioned technical scheme, press easily detaining the mechanism down, the switching state of shelves portion 3 is the lock, and the elastic cord is taut, makes half face guard laminating face.
In the above technical solution, when the easy-to-buckle mechanism is lifted, the switching state of the gear portion 3 is unlocked, and the elastic band is released, so that the half mask is separated from the face.
In the technical scheme, a gap is reserved at the joint of the root of the connecting guide pillar 1 and the mouth and nose cover.
In the technical scheme, the elastic band is used for connecting the head band, the easy-buckling mechanism and the mouth and nose cover cap, namely, the upper end elastic band of the half mask penetrates through the elastic band positioning hole 2 of the easy-buckling mechanism by the head band and then penetrates through the mouth and nose cover cap, and the easy-buckling mechanism is combined with the mouth and nose cover cap.
The utility model discloses an easy knot mechanism that industry face guard just taken and reset compares with prior art, and beneficial effect is:
1. the prior art has no easy-buckling mechanism, two long elastic belts directly surround the head, or four elastic belts are buckled and locked together and surround the head, so that the elastic belts have no reserved space, the oronasal mask cover needs to be pulled manually and then buckled, and the oronasal mask cover is loosened by repeated operation, so that the oronasal mask cover is uncomfortable to fit the face and leaks air; on the other hand, the user can grasp the bad position when the mouth and nose cover is buckled, so that the air leakage occurs due to the deviation.
And the utility model designs an easy mechanism of detaining, the upper end elastic cord of half face guard passes the elastic cord locating hole of easy mechanism of detaining by the bandeau after, passes the oronasal shroud again, will easily detain the mechanism and make up with oronasal shroud.
