Description
Technical field
The utility model relates to a kind of insulated protective equipment, and more particularly, it relates to a kind of insulation protective jacket.
Background technology
Spanner is a kind of conventional installation and removal instrument.Utilize lever principle to twist bolt, screw, nut and other screw threads and tightly hold the opening of bolt or nut or the hand tools of trepanning firmware.Spanner is usually shaped with clamp holder portion and applies external force shank and apply external force in the one or both ends of shank, just can twist opening or trepanning that bolt or nut hold bolt or nut.During use, threadingly direction of rotation applies external force at shank, just can twist bolt or nut.Because because spanner also may can be used to forceful electric power construction, in order to ensure construction safety, generally all increasing insulation sleeve at the handle portion of spanner, by people's grasped insulation sleeve, forceful electric power isolation being carried out to construction parts, ensure that the security of construction.
But in use find, be that its insulating properties or its convenience used all have much room for improvement, particularly conventional on market insulation sleeve only serves insulating properties, and does not make improvement in increasing friction force, makes easily to skid when using.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of by increasing its surperficial radian, and making it more can fit with human hands increases frictional force and prevent from skidding, simultaneously by increase band raising creep age distance raising insulating properties.
For achieving the above object, the utility model provides following technical scheme: a kind of insulation protective jacket, comprise a cavity volume, described cavity volume is for being sheathed on the handle of spanner, and with the handle interference fit of spanner, described insulation protective jacket comprises the first outer surface that transition is successively arranged, second outer surface, 3rd outer surface and the 4th outer surface, described insulation protective jacket also comprises grip part and press section, described grip part comprises and is arranged at some first of the first outer surface and grasps cambered surface and be arranged at some second of the 3rd outer surface and grasp cambered surface, described first grasping cambered surface and second grasps globoidal mirror picture and arranges, described first grasping cambered surface and the second outer surface transition have First Transition cambered surface, described second grasping cambered surface and the second outer surface transition have the 3rd transition cambered surface, described first grasp cambered surface with all round surface transition have the second transition cambered surface, described second grasping cambered surface and all round surface transition has the 4th transition cambered surface, described press section comprises some first grooves being arranged at the first outer surface and some second grooves being arranged at the 3rd outer surface, and the described first equal interval of groove arranges and forms band at interval, and described second groove and the first groove mirror image are arranged.
By such setting, when user in use, can finger grip grip part, the second knuckle that example first grasps cambered surface and finger is fitted, First Transition cambered surface is fitted with regard to nature and third knuckle and the second transition cambered surface is correspondingly fitted with first knuckle, thus make to grasp whole finger can be fitted with the perfection of the insulation sleeve of the utility model application, increase its contact area thus play increase frictional force, prevent the effect of skidding, and thumb can be prevented in use putting the 3rd outer surface in press section, during such use, the effect of auxiliary force is played by thumb press, band can ensure its frictional force simultaneously, prevent thumb from skidding because of overstress in force process, and arranging of groove can increase its creep age distance, user is when live line work, thumb is made to leave press section, hand only contacts with grip part, ensure that its insulating properties.Similarly, when due to space and environmental limit, one direction rotation can only be carried out to spanner, so just can accordingly, by finger grip in grip part, the second knuckle that can grasp cambered surface and finger with second is accordingly fitted, 3rd transition plane just nature and third knuckle is fitted, and the second transition cambered surface is fitted with second knuckle similarly naturally, same effect can be played, practicality of the present utility model can be increased again.
The utility model can be set to further: described insulation protective jacket is also provided with hanging hole.By the setting of hanging hole, can hang over when not using on any projection or clothes-hook, ensureing its stability of laying.
The utility model can be set to further: described hanging hole is communicated with cavity volume and arranges.Arrange by hanging hole is communicated with cavity volume, can, when the handle of spanner is inserted cavity volume, air be discharged from hanging hole, ensure that its can not after be full of insert time mineralization pressure, cause being difficult to inserting.
The utility model can be set to further: described press section comprises the first vertical line and the second vertical line, and described first vertical line divides equally the first groove, and described second vertical line divides equally the second groove.By the setting of vertical line, when exerting a force, thumb acts on the staggered position of band and vertical line, forms the face that interlocks one by one, ensure that its lifting surface area, and the setting of groove, frictional force when it uses can be ensured.
The utility model can be set to further: described first grasps cambered surface quantity is set to three.Grasped the setting of cambered surface by three first, just in time can point (forefinger, middle finger and the third finger) with three and coordinate, ensure that its stressed quantity.Same, grasp that globoidal mirror picture arranges with first second grasps cambered surface quantity is also set to three, ensures that it is stressed.
By adopting technique scheme, serving following beneficial effect: add creep age distance, improve the insulating properties of the insulation sleeve described in the utility model, further reduce potential safety hazard, simultaneously by the setting of grip part and press section, increase its frictional force, ensure that it normally uses.
