Detailed description of the invention
For the ease of those skilled in the art's understanding, below in conjunction with accompanying drawing, the utility model will be further described.
Because compound rod can laterally be placed and vertically placement, and can turn round up and down, therefore described " upper end " and " lower end " all arranges for ease of description in full, conduct is not to restriction of the present utility model.
As depicted in figs. 1 and 2, a kind of compound rod of anticreep fast assembling-disassembling, comprises outer bar 1 and interior bar 2, the lower end of outer bar 1 offers axial slits 11, outer bar 1 lower end is placed on interior bar 2 upper ends, and the appearance match profiles of the inner surface contour of outer bar 1 and interior bar 2 is closed, and outer bar 1 is held interior bar 2 tightly by latching device.Latching device comprises the gripping sleeve 3 that is placed on outer bar 1 lower end and the edge quick detach spanner 4 with cam-like top laminated structure 41, and the appearance match profiles of the inner surface contour of gripping sleeve 3 and outer bar 1 is closed.The side of gripping sleeve 3 is provided with breach 31, and the both sides of breach 31 are equipped with journal stirrup 32, two journal stirrups 32 and are provided with corresponding through hole, between top laminated structure 41 and journal stirrup 32, are provided with friction lining 6, prevents top laminated structure 41 directly and journal stirrup 32 rubs and weares and teares.On top laminated structure 41, be interspersed with rotating shaft 5, speed wrench 4 rotates around this rotating shaft 5.On through hole, be interspersed with adjusting bolt 7, adjusting bolt 7 is twisted in rotating shaft 5 through friction lining 6.
As shown in Fig. 3, Fig. 4 and Fig. 5 (in conjunction with Fig. 1), the inside face of quick detach spanner 4 is provided with block tongue 42, and gripping sleeve 3 is provided with draw-in groove 34, and outer bar 1 is provided with groove 13, and when 4 fastening of quick detach spanner, block tongue 42 is stuck in draw-in groove 34 and groove 13 simultaneously.
As shown in Fig. 6 and Fig. 7 (in conjunction with Fig. 2), the inwall of gripping sleeve 3 is provided with the profile 33 of protrusion, and profile 33 arranges vertically, and interior bar 2 is provided with the catching groove 21 coordinating with profile 33, outer bar 1 is provided with profile gap 12, and profile 33 is buckled in catching groove 21 through profile gap 12.
The installation process of the present embodiment is: first assemble latching device, detailed process is for to insert rotating shaft 5 in speed wrench 4, the through hole that adjusting bolt 7 is passed on journal stirrup 32, again by adjusting bolt 7 through friction lining 6 rear twist with rotating shaft 5 on, adjust adjusting bolt 7 to suitable degree of tightening, latching device assembling is complete; Then pass through profile 33 and catching groove 21 by fixing gripping sleeve 3 and interior bar 2; Then outer bar 1 is inserted in the space between gripping sleeve 3 and interior bar 2; Then speed wrench 4 is rotated to fastening along rotating shaft 5, now friction lining 6 is pressed on laminated structure 41 tops in top, thereby journal stirrup 32 is pressed on top, the breach 31 of gripping sleeve 3 reduces, the cross section of gripping sleeve 3 reduces, so compressing outer bar 1 lower end cross section reduce, thereby make outer bar 1 hold interior bar 2 tightly, now block tongue 42 is stuck in draw-in groove 34 and groove 13 simultaneously, avoids gripping sleeve 3 and outer bar 1 to occur sliding axially.So far, outer bar 1 is held interior bar 2 tightly, and gripping sleeve 3 fixes with outer bar 1 and interior bar 2 respectively in the axial direction, has effectively played anticreep effect, makes outer bar 1 more firm with being connected of interior bar 2.When dismounting, only speed wrench 4 oppositely need be moved along rotating shaft, can remove the locking of interior bar 2 and outer bar 1, can disassemble easily interior bar 2 and outer bar 1.
Above-described embodiment is preferably implementation of the utility model, and without departing from the concept of the premise utility, the replacement of just the utility model being made direct displacement or being equal to, within all belonging to protection domain of the present utility model.
