Abstract
The invention discloses a double protection combined type dual-use anti-explosion F-shaped wrench which comprises an F-shaped wrench body made of a steel tube. A rigid unplasticised polyvinyl chloride (PVC-U) layer covers the surface of the F-shaped wrench body except the positions of two wrench teeth on the thumb-index web, and a sleeve is movably fixed on each wrench tooth on the thumb-index web. Each sleeve is composed of an inner copper piece layer or an inner copper alloy piece layer and the outer rigid PVC-U layer, and a copper piece layer or a copper alloy piece layer is arranged between the rigid PVC-U layer on the inner side of the thumb-index web except the wrench teeth and a steel tube layer. The F-shaped wrench body is made of the steel tube, the rigid PVC-U layer covers the outer side of the F-shaped wrench body, and therefore the F-shaped wrench body made of the steel tube is fully covered, and sparks caused by the wrench falling on the ground from a slippery hand are avoided. Due to the fact that the inner side of the thumb-index web of the anti-explosion F-shaped wrench is protected by the copper piece layer or the copper alloy piece layer and the rigid PVC-U layer, the F-shaped wrench has the function of preventing the sparks caused by collision of steel and preventing explosion when used.
Description
Technical field:
The invention belongs to the fire-fighting equipment field, be specifically related to the explosion-proof F spanner of a kind of double shielding combined dual-purpose.
Background technology:
In the existing valve opening instrument, " F " shape spanners that adopt more, the explosion-proof spanner of " F " shape is the on-the-spot indispensable operation tool of Chemical Manufacture, because the explosion-proof spanner of " F " shape must possess explosion prevention function, therefore the present explosion-proof spanner of " F " shape is to be made by copper or copper alloy basically, and copper is expensive, and it is high to reclaim price, often stolen.Therefore stolen in order to prevent, the explosion-proof spanner of " F " shape generally all can indoor collection, and the device scene does not have.When in case of emergency, must remove the indoor explosion-proof spanner of " F " shape of taking, will cause the quality time of delaying emergency, cause possibly great life and property loss.
Summary of the invention:
The purpose of this invention is to provide a kind of with low costly, copper seldom, and is simple in structure, and service time is long, has simultaneously the explosion-proof F spanner of double shielding combined dual-purpose of double shielding effect.
The explosion-proof F spanner of double shielding combined dual-purpose of the present invention; comprise the F wrench body; it is characterized in that; described F wrench body is to be made by steel pipe; except two spanner tooth places of tiger’s jaw, its elsewhere all cover one deck PVC-U PVC-U layer on F wrench body surface; all activity is fixed with sleeve on two spanner teeth of tiger’s jaw; this sleeve is comprised of the copper of internal layer or copper alloy lamella and outer field PVC-U PVC-U layer, also has copper or copper alloy lamella between the PVC-U PVC-U layer at the inboard non-spanner tooth of tiger’s jaw place and steel pipe layer.
Preferably, tiger’s jaw on the F wrench body with respect to an other side be provided with two copper or copper alloy spanner tooth forms the second tiger’s jaw, two copper or copper alloy spanner tooth are threaded with the F wrench body, formed thus little F spanner, size F spanner is fit to the valve of different size, plays the effect of dual-use material.
Described sleeve comprises sleeve pipe and the plug that is comprised of the copper of internal layer or copper alloy lamella and outer field PVC-U PVC-U layer, plug inside is provided with external thread column, steel pipe inboard at the spanner tooth has internal thread, sleeve pipe is placed on the spanner tooth, the end of sleeve pipe snaps in the plug, the internal thread of the steel pipe inboard by the inner external thread column of plug and spanner tooth is threaded, and the sleeve pipe activity is fixed on the spanner tooth.
Preferably also wrap up one deck ballistic nylon or aramid fiber or basic synthetic fibre fibrage in described copper or copper alloy lamella outside, for copper or copper alloy lamella provide stronger protection.
The present invention makes the F wrench body with steel pipe, covers one deck PVC-U PVC-U layer outside the F wrench body, so just the F-shaped wrench body of steel pipe material is all wrapped, and produces spark so need not be afraid of hand to slip out lower ground.Between the PVC-U of tiger’s jaw inboard PVC-U layer and F wrench body steel pipe, have layer of copper or copper alloy lamella; PVC-U PVC-U layer has certain hardness; the tiger’s jaw of anti-riot F spanner is inboard owing to have copper or copper alloy lamella and the two-layer protection of PVC-U PVC-U layer; so just can prevent in use; play preventing that iron and steel from colliding and the generation spark, play anti-riot function.The movable fixed cover of sleeve so just can avoid sleeve not to be durable, thereby the sleeve that can in time more renew extends working time on the spanner tooth.
Description of drawings:
Fig. 1 is the structural representation of the explosion-proof F spanner of double shielding combined dual-purpose of the present invention;
Wherein 1, F wrench body; 2, PVC-U PVC-U layer; 31, spanner tooth A; 32, spanner tooth B; 41,42,43, brass lamella; 51,52, plug; 61, spanner tooth C; 62, spanner tooth D; 71,72, PVC-U PVC-U layer.
The specific embodiment:
Following examples are to further specify of the present invention, rather than limitation of the present invention.
Embodiment 1:
As shown in Figure 1; the explosion-proof F spanner of the double shielding combined dual-purpose of present embodiment comprises external diameter 25mm; the F wrench body 1 that the carbon steel pipe of wall thickness 8mm is made; on F wrench body 1 surface except the spanner tooth A 31 and spanner tooth B 32 places of tiger’s jaw; its elsewhere all covers one deck PVC-U PVC-U layer 2; the spanner tooth A 31 of tiger’s jaw and spanner tooth B 32 all activity be fixed with sleeve; described sleeve comprises the thick brass lamella 41 of 0.3mm by internal layer; 42 and the thick PVC-U PVC-U layer 71 of outer field 2.5mm; 72 sleeve pipe and the plugs 51 that form; 52; plug 51; 52 inside are provided with external thread column; steel pipe inboard at spanner tooth A 31 and spanner tooth B 32 has internal thread; sleeve pipe is placed on spanner tooth A 31 and the spanner tooth B 32; the end of sleeve pipe snaps in plug 51; in 52; by plug 51; the external thread column of 52 inside is threaded with the internal thread of the steel pipe inboard of spanner tooth A 31 and spanner tooth B 32, and the sleeve pipe activity is fixed on spanner tooth A 31 and the spanner tooth B 32.Between the PVC-U PVC-U layer at the inboard non-spanner tooth of tiger’s jaw place and steel pipe layer, also has the thick brass lamella 43 of 0.3mm.The other side that tiger’s jaw on the F wrench body is relative is provided with the brass spanner tooth of two diameter 8mm, length 35mm-spanner tooth C 61 and spanner tooth D 62, form the second tiger’s jaw, spanner tooth C 61 and spanner tooth D 62 are threaded with the F wrench body, formed thus little F spanner, size F spanner is fit to the valve of different size, plays the effect of dual-use material.
