Abstract
The utility model discloses a kind of telescopic sleeve, comprising: sleeve body, comprise main shaft and be arranged at the lever of this main shaft one end; Sleeve, be hollow in this sleeve, this main shaft moves back and forth in the sleeve of this hollow until the end that this main shaft is not provided with lever contacts with the screw rod of nut to be assembled; And locking nut, this locking nut passes cartridges sides and is fixed on main shaft.The lower end of described sleeve is provided with the slotted eye cooperatively interacted with nut.Described sleeve inner side mounting thread, described main shaft lateral surface is provided with the screw thread cooperatively interacted with the screw thread of this sleeve medial surface.The utility model overcomes existing sleeve can not to the defect of nut check with long bolt, and this extension sleeve freely can adjust the scope of application according to the spiro rod length of the nut of assembling, reaches the object of the nut check to long bolt.
Description
Technical field
The utility model relates to field of machining, especially, relates to a kind of telescopic sleeve.
Background technology
Bolt or nut are conventional fasteners, are all to give fastening with common wrench or screw driver when it is fastening.Under special installation environment, when it is fastening, box spanner will be used.The function ratio of current box spanner is more single, and the spiro rod length that general sleeve adapts to is fixing.
When needing to assemble to the nut with the screw rod exceeding length sleeve, only have and twist locking back and forth by back-up wrench or monkey wrench, the mode for this type of screw assembling nut is assembled in order to batch nut, and efficiency is too slow.
Utility model content
The utility model object is to provide a kind of telescopic sleeve, to solve in prior art when exceeding the screw assembling nut of its length, only have and twist locking back and forth by back-up wrench or monkey wrench, mode for this type of screw assembling nut is assembled in order to batch nut, the problem that efficiency is too slow.
For achieving the above object, the utility model provides a kind of telescopic sleeve, wherein, comprising: sleeve body, comprises main shaft and is arranged at the lever of this main shaft one end; Sleeve, be hollow in this sleeve, this main shaft moves back and forth in the sleeve of this hollow until the end that this main shaft is not provided with lever contacts with the screw rod of nut to be assembled; And locking nut, this locking nut passes cartridges sides and is fixed on main shaft.
Further, the utility model provides a kind of telescopic sleeve, and wherein, the lower end of described sleeve is provided with the slotted eye cooperatively interacted with nut.
Further, the utility model provides a kind of telescopic sleeve, and wherein, described sleeve inner side mounting thread, described main shaft lateral surface is provided with the screw thread cooperatively interacted with the screw thread of this sleeve medial surface.
The utility model has following beneficial effect: the utility model provides a kind of extension sleeve, overcoming existing sleeve can not to the defect of nut check with long bolt, this extension sleeve freely can adjust the scope of application according to the spiro rod length of the nut of assembling, reaches the object of the nut check to long bolt.
Accompanying drawing explanation
Below with reference to figure, the utility model is described in further detail.The accompanying drawing forming a application's part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
Refer to Fig. 1, preferred embodiment of the present utility model provides a kind of telescopic sleeve, to solve in prior art when exceeding the screw rod assembling nut of its length, only have and twist locking back and forth by back-up wrench or monkey wrench, mode for this type of assembling nut is assembled in order to batch nut, the problem that efficiency is too slow.
Wherein, described telescopic sleeve comprises: sleeve body, sleeve 3 and locking nut 2.
Again, described sleeve body comprises main shaft 5 and lever 1, and this lever 1 is arranged at this main shaft 5 one end; Described sleeve 3 inner side mounting thread, described main shaft 5 lateral surface is provided with the screw thread cooperatively interacted with the screw thread of this sleeve 3 medial surface, be hollow in this sleeve 3, this main shaft 5 moves back and forth in the sleeve 3 of this hollow, until the end that this main shaft 5 is not provided with lever 1 contacts with the screw rod of nut 4 to be assembled; This locking nut 2 correspondence passes the side of sleeve 3 and is fixed on main shaft 5.
The lower end of described sleeve 3 is provided with slotted eye 6, and this slotted eye 6 cooperatively interacts with nut 4 to be assembled.
So, when needs assembling nut 4, first nut 4 is positioned over place to be assembled, then lever 1 is rotated, utilize the cooperation between screw thread, this main shaft 5 rotates to make this main shaft 5 move back and forth in the sleeve 3 of this hollow in sleeve 3, until the screw rod of this main shaft 5 end and nut 4 to be assembled of not being provided with lever 1 contacts with each other, this locking nut 2 correspondence passes the side of sleeve 3 and rotation is fixed on main shaft 5, so, just this has the extension sleeve of the nut of certain length screw rod can to assemble corresponding dismounting, sleeve 3 is inserted on nut 4, the screw rod correspondence of described nut 4 to be assembled is inserted in the slotted eye 6 that the lower end of this sleeve 3 is provided with, so, just can tighten easily or unscrew nut 4, and instrument need not be changed, very convenient.
From above description, can find out, the utility model the above embodiments achieve following technique effect: the utility model provides a kind of extension sleeve, overcoming existing sleeve can not to the defect of nut check with long bolt, this extension sleeve utilizes sleeve internal and external threads to rotate so that be applicable to have nut and the screw thread fixation principle of different length screw rod, spiro rod length according to the nut of assembling freely adjusts the scope of application, reaches the object of the nut check to long bolt.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model; For a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
