Description
Technical field
The present invention relates to the handwheel technical field of connector, be specifically related to one and hold and length-adjustablely determine moment handwheel.
Background technology
In field of connectors, some connectors need restriction screw moment and arrive bit-identify clearly, therefore need to use and determine moment structure (i.e. handwheel).But some use occasion, the cable that handwheel is connected device sandwiches, and causes holding easily screwing.Therefore needing a kind ofly can extend the hand wheel structure holding position, the distance holding position and cable double team place can be increased when not using frock, reduce and screw difficulty.
Summary of the invention
The object of the invention is the deficiency for solving the problems of the technologies described above, providing one to hold and length-adjustablely determining moment handwheel, the holding part bit length of handwheel can be lengthened according to different operating modes.
The present invention is the deficiency solved the problems of the technologies described above, the technical scheme adopted is: one is held and length-adjustablely determined moment handwheel, comprise nut and lining, lining is arranged in nut, can axial displacement between nut and lining, described lining comprises the different large-diameter portion of internal diameter and minor diameter part, forming station terrace between large-diameter portion and minor diameter part, the large-diameter portion of described lining is provided with annular hard liner near step surface one end, hard liner is compressed by the thread bush be arranged in lining large-diameter portion, hard liner is evenly provided with multiple through hole vertically, inner sleeve is provided with in the minor diameter part of described lining, can relatively rotate between inner sleeve and lining, inner sleeve is evenly provided with passage vertically, in passage, hard liner one end is provided with steel ball, the diameter of steel ball is greater than the diameter of through hole on hard liner, the other end in described passage arranges fastener, spring is provided with between steel ball and fastener, original state, a part for steel ball embeds in the through hole of hard liner.
Described lining is provided with and organizes groove more, on the sidewall of nut, correspondence is often organized groove and is provided with a bail, often organize groove and comprise elongated slot vertically and short groove, be communicated with by groove circumferentially between elongated slot and short groove, be provided with elastic component in described thread bush, one end of elastic component is fixedly connected with hard liner, original state, bail is fastened in short groove, and elastic component holds out against nut and arranges.
beneficial effect
1, handwheel of the present invention has and determines moment function, when screw-down torque reaches default value, rotate the pretightning force that the component produced exceedes spring, steel ball now in inner sleeve can be deviate from the through hole of hard liner, hard gasket end face slips over, thus forming skidding, idle running, the decrement by regulating spring can realize the restriction of different moment.
2, handwheel of the present invention holds adjustable length, when position is held in needs prolongation, is slided in elongated slot by nut bail in short groove, and moves to the bottom land position of elongated slot, achieves axial displacement between nut and lining, and the position of holding of handwheel is lengthened.

Detailed description of the invention
As Fig. 1, shown in 2, one is held and is length-adjustablely determined moment handwheel, comprise nut 1 and lining 2, lining 2 is arranged in nut 1, described lining 2 comprises the different large-diameter portion of internal diameter and minor diameter part, forming station terrace between large-diameter portion and minor diameter part, the large-diameter portion of described lining 2 is provided with annular hard liner 3 near step surface one end, the internal diameter of hard liner 3 is less than the internal diameter of lining 2 minor diameter part, lining 2 large-diameter portion has screw thread on the inwall of end, thread bush 4 is provided with in this thread segment of lining 2, hard liner 3 is compressed by the thread bush 4 be arranged in lining 2 large-diameter portion, first load hard liner 3, then thread bush 4 is rotated until be tightly clipped between thread bush 4 and step surface by hard liner 3.Hard liner 3 is evenly provided with multiple through hole 5 vertically, inner sleeve 6 is provided with in the minor diameter part of described lining 2, can relatively rotate between inner sleeve 6 and lining 2, inner sleeve 6 is evenly provided with passage 7 vertically, in passage 7, hard liner 3 one end is provided with steel ball 8, the diameter of steel ball 8 is greater than the diameter of through hole 5 on hard liner 3, the other end in described passage 7 arranges fastener 9, spring 10 is provided with between steel ball 8 and fastener 9, original state, steel ball 8 under the effect that holds out against of spring 10, one is partially submerged in the through hole 5 of hard liner 3.During rotating screw cap 1, nut 1 drives lining 2 to rotate by bail 101, and hard liner 3 can be driven when lining 2 rotates together to rotate, and the part due to steel ball 8 embeds in the through hole 5 of hard liner 3, when screw-down torque does not reach default value, inner sleeve 6 can be driven to rotate; When screw-down torque reaches default value, rotate the pretightning force that the component produced exceedes spring 10, steel ball 8 now in inner sleeve 6 can be deviate from the through hole 5 of hard liner 3, hard gasket 3 end face slips over, the now rotation of nut 1 can not drive the rotation of inner sleeve 6, forms skidding, idle running.
As shown in Figure 3,4: can axial displacement between nut 1 and lining 2, axial displacement between nut 1 and lining 2 can be realized by following structure: lining 2 is provided with and organizes groove more, on the sidewall of nut 1, correspondence is often organized groove and is provided with a bail 101, the corresponding lining 2 of the distribution of bail 101 on nut 1 sidewall is often organized the position of groove.Often organize groove and comprise elongated slot 201 vertically and short groove 202, elongated slot 201 and short groove 202 are all extended towards the end face of lining 2 one end from nut 1, and between elongated slot 201 and short groove 202, the groove 203 passed through circumferentially is communicated with.Be provided with elastic component 204 in described thread bush 4, one end of elastic component 204 is fixedly connected with hard liner 3, original state, and bail 101 is fastened in short groove 202, and elastic component 204 holds out against nut 1 and arranges.As shown in Figure 5: when position is held in needs prolongation, the bail 101 of nut 1 is slided in elongated slot 201 through groove 203 in short groove 202, and move to the bottom land position of elongated slot 202, achieve axial displacement between nut 1 and lining 2, the position of holding of handwheel is lengthened.
