Description
Technical field
The present invention relates to labor protection product technical fields, 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, thickness, impact energy and static pressure
Safety standard, have to this anti-hardness for pounding packet header and shape it is certain be particular about, when in the vamp for being put into footwear front end, resist
Pounding packet header can make that the front end of footwear is full well-pressed and hard, is unlikely to deform, therefore cannot be after packet header is depressed in the front end sewing of footwear
Line processed, the use produced on the market now meet the anti-safety footwear product for pounding packet header of national safety standard, are all mostly
Vamp is fixed on close to the part of sole on sole by gluing or Shooting Technique behind packet header on set, because of vamp and footwear
The engaging portion at bottom is that shoe user is easiest to the part pullled, be lost during the motion, therefore made using this technique
The shortcomings that safety shoe is that usage time easily cracks once growing its engaging portion, so as to lose the effect of safety shoe protection foot,
And the vamp of this safety shoe with binder adhesive and the engaging portion of sole pollute the environment when adhesive comes unglued, it is impossible to
Play the effect of environmental protection.The anti-safety footwear product for pounding packet header that use on the market meets national safety standard now also has one
The safety shoe that kind is manufactured using suture technique, as shown in Figure 1, between the side of this safe instep 12 and the edge of sole 40
There are one not wide plane 50, the shoe-making process of this safety shoe passes through painting for the packet header 30 on set and after having bonded vamp 12
The vamp 12 of 30 part of packet header is fixed on close to the part of sole 40 on sole by glue or Shooting Technique, then in sole 40 close to packet
The edge strip of produced line simulator is sticked in the plane 50 of first 30 part to ensure beauty, will be removed then through sewing technology close
Other vamps 12 outside 30 part of packet header are stitched together close to the part of sole 40 and footwear lining 11 and sole 40, in suture
When needlework can pass through footwear lining, in plane 50 and the inside of sole 40, the shortcomings that safety shoe is vamp for the position of needlework knot
12nd, footwear lining 11 has been sewn to together with sole 40, and needlework break through footwear lining 11, and this safety shoe is non-watertight, if in the rainy day
Wearing this safety shoe, then rainwater is easily entered through footwear lining in footwear by needlework hole, so as to hamper the convenience of walking, is influenced
The comfort of shoe user.
In addition it is existing it is anti-to pound protective footwear its basic role be exactly that toe portion has the anti-protection pounded, threading trouble is applicable in
Shoe style is few, being applicable in size, few, shoe style divides equally left and right foot, and not very docile is also easy to cause security risk, such as ground is slightly
Perhaps in the case of some cunnings, personnel's very capacity is fallen.Crossing process trouble easily makes loose rib tape dirty, and operation by human hand easily contact is thin
Bacterium etc..
Invention content
The purpose of the present invention is to overcome the defects in the prior art, provides a kind of simple in structure, safe to use, dress side
When just, wearing can regardless of left and right foot, size can arbitrarily adjust, low-cost security protection shoe cover.
To achieve the above object, the technical scheme is that designing a kind of security protection shoe cover, the safety shoe
Set include antisquashy shoe head and followed by sheath section, the sole of the antisquashy shoe head and forefoot be connected as a single entity, it is described followed by protect
The sole of set portion and rear heel is connected as a single entity, and passes through adjustable grafting between the sole of the forefoot and the sole of rear heel
Structure connect, the adjustable connected structure include be arranged on forefoot the interlayer of sole in sliding slot, the sliding slot with
The sliding block cutting being arranged on the sole of rear heel is slidably matched, and Flexible Reset portion is equipped between the sliding slot and sliding block cutting
Part, is equipped with ratchet bar in the sliding slot, and the ratchet bar and the claw snap into engagement of sliding block cutting end, the claw pass through
Sliding block cutting is connect with claw conjugate control end, and the claw conjugate control end is arranged on the rear portion of the sole of rear heel.
The forepart of one foot puts in antisquashy shoe head during use, and the claw that another foot is scrunched downwards in heel of a shoe portion is nibbled
Close control terminal, then by heel parts enter into followed by sheath section in, then in the heel of a shoe portion that another foot is scrunched downwards
Claw conjugate control end is decontroled, and again can be put on another safety shoe set with same method.When another foot to
Under when scrunching the claw conjugate control end in heel of a shoe portion, the ratchet bar that is arranged in the midsole internal chute of forefoot,
It being disengaged from the claw of its end of sliding block cutting being arranged on the sole of rear heel, sliding block cutting can be slided along sliding slot, and
And under the drawing of Flexible Reset component, may be such that antisquashy shoe head with followed by the entirely appropriate wearer of sheath section foot, and
After another foot releases the claw conjugate control end in heel of a shoe portion, ratchet bar and the claw buckle of sliding block cutting end are nibbled
It closes, its connection fixation is made to be not easy to loosen.
In order to enable being connected firmly between the sole of forefoot and the sole of rear heel, smooth running after dress is not easy to turn round
Song deformation comes off, and preferred technical solution is that the sliding slot is equipped with twice, and the twice sliding slot is separately positioned on forefoot
