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 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 existing valve opening instrument, many employings " F " shape spanner, the explosion-proof spanner of " F " shape is the operation tool of chemical industry production site indispensability, because the explosion-proof spanner of " F " shape must possess explosion prevention function, therefore the current explosion-proof spanner of " F " shape is be made up of copper or copper alloy substantially, and copper processing is expensive, unit take-back cost is high, often stolen.Therefore stolen to prevent, the explosion-proof spanner of " F " shape generally all can indoor collection, and device scene does not have.When in case of emergency, must go indoor by the explosion-proof spanner of " F " shape, the quality time delaying emergency will be caused, cause great life and property loss possibly.
Summary of the invention:
The object of this invention is to provide a kind of with low cost, copper is little, and structure is simple, and service time is long, has the explosion-proof F spanner of double shielding combined dual-purpose of double shielding effect simultaneously.
The explosion-proof F spanner of double shielding combined dual-purpose of the present invention; comprise F wrench body; it is characterized in that; described F wrench body is made up of steel pipe; one deck PVC-U PVC-U layer is all covered in its elsewhere except two spanner tooth places of tiger's jaw, F wrench body surface; on two spanner teeth of tiger's jaw, all activity is fixed with sleeve; this sleeve is made up of the copper of internal layer or copper alloy lamella and outer field PVC-U PVC-U layer, inside tiger's jaw, also have copper or copper alloy lamella between the PVC-U PVC-U layer at non-spanner tooth place and steel pipe layer.
Preferably, tiger's jaw in F wrench body relative to 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 F wrench body, thus form little F spanner, size F spanner is applicable to the valve of different size, plays effect of dual-use material.
Described sleeve comprises the sleeve pipe and plug that are made up 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, inside the steel pipe of spanner tooth, there is internal thread, sleeve pipe is placed on spanner tooth, the end of sleeve pipe snaps in plug, be threaded by the internal thread inside the steel pipe of the inner external thread column of plug and spanner tooth, sleeve pipe activity is fixed on spanner tooth.
One deck ballistic nylon or aramid fiber or base synthetic fibre fibrage is preferably also wrapped up, for copper or copper alloy lamella provide stronger protection outside described copper or copper alloy lamella.
F wrench body made by the present invention's steel pipe, covers one deck PVC-U PVC-U layer outward, so just the F-shaped wrench body of steel pipe material is all wrapped in F wrench body, so need not be afraid of that hand slips out lower ground and produces spark.PVC-U PVC-U layer inside tiger's jaw and between F wrench body steel pipe, there is one deck copper or copper alloy lamella; PVC-U PVC-U layer has certain hardness; owing to having copper or copper alloy lamella and the two-layer protection of PVC-U PVC-U layer inside the tiger's jaw of anti-riot F spanner; so just can prevent in use; play and prevent iron and steel from colliding and producing spark, play anti-riot function.The movable fixed cover of sleeve, on spanner tooth, so just can avoid sleeve not to be durable, thus the sleeve that can more renew in time, extend working time.
Accompanying drawing illustrates:
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.
Detailed description of the invention:
Following examples further illustrate of the present invention, instead of limitation of the present invention.
Embodiment 1:
As shown in Figure 1, the explosion-proof F spanner of double shielding combined dual-purpose of the 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 of tiger's jaw and spanner tooth B 32 place, 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 by the thick brass lamella 41 of the 0.3mm of internal layer, 42 and the thick PVC-U PVC-U layer 71 of outer field 2.5mm, the sleeve pipe of 72 compositions and plug 51, 52, plug 51, 52 inside are provided with external thread column, inside the steel pipe of spanner tooth A 31 and spanner tooth B 32, there is internal thread, sleeve pipe is placed on spanner tooth A 31 and 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 inside the steel pipe of spanner tooth A 31 and spanner tooth B 32, sleeve pipe activity is fixed on spanner tooth A 31 and spanner tooth B 32.Inside tiger's jaw, between the PVC-U PVC-U layer at non-spanner tooth place and steel pipe layer, also there is the thick brass lamella 43 of 0.3mm.The other side that tiger's jaw in F wrench body is relative is provided with two diameter 8mm, the brass spanner tooth-spanner tooth C 61 of length 35mm and spanner tooth D 62, form the second tiger's jaw, spanner tooth C 61 and spanner tooth D 62 is threaded with F wrench body, thus form little F spanner, size F spanner is applicable to the valve of different size, plays effect of dual-use material.
