Description
Technical field
The present invention relates to labor protection product technical field, and in particular to a kind of security protection shoe cover.
Background technology
It is both needed to reach country containing safety indexs such as the anti-safety footwear product for pounding packet header, its thickness, impact energy and static pressure
Safety standard, this anti-hardness and shape for pounding packet header is had it is certain be particular about, when being put in the vamp of footwear front end, resist
Pounding packet header can make that the front end of footwear is full well-pressed and hard, be unlikely to deform, therefore can not be behind pressure packet header in the front end sewing of footwear
Line processed, the employing for producing on the market now meets the anti-safety footwear product for pounding packet header of national safety standard, and it is all mostly
Behind packet header on set vamp is fixed on sole near the part of sole by gluing or Shooting Technique, because vamp and footwear
The joint portion at bottom is the part that shoe user is easiest to be pullled, be lost in motion process, therefore made using this technique
The shortcoming of safety shoe is that use time easily ftractures once growing its joint portion, so as to lose the effect that the safety shoe protects pin,
And this vamp of the safety shoe with binder adhesive pollutes the environment with the joint portion of sole when adhesive comes unglued, it is impossible to
Play the effect of environmental protection.Employing on the market now meets the anti-safety footwear product for pounding packet header of national safety standard and also has one
The safety shoe manufactured using suture technique is planted, as shown in figure 1, between the side of this safe instep 12 and the edge of sole 40
There is not wide plane 50, the shoe-making process of this safety shoe is packet header 30 and to have bonded after vamp 12 on set, by applying
Glue or Shooting Technique are fixed on the vamp 12 of the part of packet header 30 on sole near the part of sole 40, then in sole 40 near bag
The edge strip that produced line simulator is sticked in the plane 50 of 30 parts is attractive in appearance to ensure, will be except near bag then through sewing technique
Other vamps 12 outside 30 parts near the part of sole 40 and footwear inside 11 and sole 40 be stitched together, in suture hour hands
Line can through footwear inside, needlework knot position in plane 50 and sole 40 inside, the shortcoming of the safety shoe is vamp 12, footwear
Inside 11 be sewn to sole 40 together with, needlework break through footwear inside 11, and this safety shoe is non-watertight, if wearing this in the rainy day
Then rainwater is entered inside in footwear safety shoe easily by needlework hole through footwear, so as to hamper the convenience of walking, have impact on wear shoes
The comfort of people.
In addition it is existing it is anti-to pound protective footwear its basic role be exactly that toe part has the anti-protection pounded, threading trouble is suitable for
Footwear type is few, few, footwear type divides equally left and right pin to be suitable for size, and not very docile is also easy to cause potential safety hazard, such as ground slightly
Perhaps in the case of some cunnings, personnel's very capacity is fallen.Crossing process bothers loose rib tape of easily making dirty, and operation by human hand easily contact is thin
Bacterium etc..
The content of the invention
It is an object of the invention to overcome defect of the prior art, there is provided a kind of simple structure, use safety, dress side
Can arbitrarily adjust regardless of left and right pin, size when just, wearing, security protection shoe cover with low cost.
For achieving the above object, a kind of security protection shoe cover of design, the safety shoe be the technical scheme is that
Set include antisquashy shoe head and followed by sheath section, the antisquashy shoe head is connected as a single entity with the sole of forefoot, described followed by protect
Set portion is connected as a single entity with the sole of rear heel, by adjustable grafting between the sole of the forefoot and the sole of rear heel
Structure connects, and the adjustable connected structure includes being arranged on chute in the interlayer of the sole of forefoot, the chute with
The slide block cutting being arranged on the sole of rear heel is slidably matched, and Flexible Reset portion is provided between the chute and slide block cutting
Part, is provided with the claw snap into engagement of ratchet bar, the ratchet bar and slide block cutting end in the chute, and the claw passes through
Slide block cutting is connected with claw conjugate control end, and the claw conjugate control end is arranged on the rear portion of the sole of rear heel.
The front portion of a pin puts in antisquashy shoe head when using, and the claw that another pin is scrunched downwards in heel of a shoe portion is nibbled
Close control end, then by heel parts enter into followed by sheath section in, then in the heel of a shoe portion that another pin is scrunched downwards
Claw conjugate control end is decontroled, and again can be put in another safety shoe set with same method.When another pin to
Under when scrunching the claw conjugate control end in heel of a shoe portion, the ratchet bar being arranged in the midsole internal chute of forefoot,
Be disengaged from the claw of its end of slide block cutting being arranged on the sole of rear heel, slide block cutting can along slide, and
And under the drawing of Flexible Reset part, can cause antisquashy shoe head with followed by the entirely appropriate wearer of sheath section foot, and
After another pin releases the claw conjugate control end in heel of a shoe portion, ratchet bar is nibbled with the claw buckle of slide block cutting end
Close so as to be connected and be difficult to loosen.
