Description

A kind of security protection shoe cover

Technical field

The utility model is related to labor protection product technical field, and in particular to a kind of security protection shoe cover.

Background technology

Containing the anti-safety footwear product for pounding packet header, the safety index such as its thickness, impact energy and static pressure is both needed to reach country Safety standard, have to this anti-hardness and shape for pounding packet header it is certain be particular about, when in the vamp for being put into footwear front end, resist Pounding packet header can make the front end of footwear full well-pressed, and it is hard, be unlikely to deform, therefore can not pressure packet header after footwear front end sewing Line processed, the use produced on the market now meets the anti-safety footwear product for pounding packet header of national safety standard, and it is all mostly Vamp is fixed on sole close to the part of sole by gluing or Shooting Technique behind packet header on set, 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 that the effect that the safety shoe protects pin is lost, And the vamp of this safety shoe with binder adhesive and the joint 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 now meets national safety standard 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 a plane 50 one not wide, the shoe-making process of this safety shoe is packet header 30 and to have been bonded on set after vamp 12, passes through and applies The vamp 12 of the part of packet header 30 is fixed on sole by glue or Shooting Technique close to the part of sole 40, then in sole 40 close to bag The edge strip of produced line simulator is sticked in the plane 50 of first 30 part attractive in appearance to ensure, will remove close then through sewing technique Other vamps 12 outside the part of packet header 30 close to the part of sole 40 and footwear inside 11 and sole 40 be stitched together, in suture When needlework can through footwear inside, the position of needlework knot in plane 50 and sole 40 inside, the shortcoming of the safety shoe is vamp 12nd, footwear inside 11 be sewn to sole 40 together with, needlework break through footwear inside 11, and this safety shoe is non-watertight, if in the rainy day Wearing this safety shoe, then rainwater is entered in footwear inside easily by needlework hole through footwear, so as to hamper the convenience of walking, is influenceed The comfort of shoe user.

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 applicable Footwear type is few, being applicable size, few, footwear type divides equally left and right pin, 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 trouble easily makes loose rib tape dirty, and operation by human hand easily contact is thin Bacterium etc..

Utility model content

The purpose of this utility model be to overcome defect of the prior art there is provided one kind it is simple in construction, using safely, wear It is convenient, can arbitrarily be adjusted regardless of left and right pin, size when wearing, security protection shoe cover with low cost.
