Description
The utility model relates to the orientable quick-disassembling fastening of a kind of tommy bar.
The quick-detachable pulling rod position structure of commonly using as shown in Figure 5, be mainly in a body of rod 23 1 ends and have thread for screw lock nut 24, end is then established one and is turned 25 in addition, pin-joint part 260 with these 25 and one tommy bar, 26 1 ends of turning articulates, be arranged with pad 27 on the body of rod 23, directly form to rub with the pin-joint part 260 of avoiding tommy bar 26 and cause quick damage with tightening piece; When this commonly uses the product combination (is the example explanation to apply to the beam tube folder), it earlier 25 is arranged in tommy bar 26 pin-joint parts 260 to turn, make the tommy bar 26 and the body of rod 23 form the pivot joint state, again pad 27 is sheathed on the body of rod 23, and this pad 27 is moved to the pin-joint part 260 of the body of rod 23, then the body of rod 23 is run through the perforation 22 of beam ring body 20 lugs 21, and with nut 24 screw locks in these body of rod 23 ends, open effect with locking as long as switching tommy bar 26 can reach control; This kind commonly used product intermediary, and to place the pad 27 between tightening piece and the pin-joint part 260 be a simple form, only can reach the effect that prevents that pin-joint part 260 from wearing and tearing fast in tightening piece, it there is no and ends effect suitably surely, thereby its tommy bar 26 is easier to stressed and any deflection pulls open, and Security is lower.
The purpose of this utility model provides the orientable quick-disassembling fastening of a kind of tommy bar.
The purpose of this utility model is to realize like this.The orientable quick-disassembling fastening of a kind of tommy bar, it comprises the body of rod, nut, tommy bar, pad, one end of the described body of rod has the thread for the described nut of screw lock, the other end articulates the pin-joint part of described plate stem, sheathed described pad on the described body of rod, and pad is pressed close to the pin-joint part of described tommy bar, it is characterized in that: described pad has fastening part near an end place, and the pin-joint part of described plate stem is provided with the matching fastening-portion that matches with described fastening part.
Described fastening part can be a kink, and this kink simultaneously is a flange, and another side then is recessed edge, and described matching fastening-portion is the recess that matches with described flange.
Described fastening part also is a bead, and described matching fastening-portion is the recess that matches with described bead.
Described blocking also can be depression, and described matching fastening-portion is the protuberance that matches with described depression.
The utility model is owing to adopt above-mentioned design proposal to make it have following advantage:
The tool tommy bar ends function surely, can prevent any deflection.It establishes fastening part on pad, and the matching fastening-portion that matches with described fastening part is established in the pin-joint part 0 of tommy bar, reaches the purpose that tommy bar ends surely by fastening part and matching fastening-portion chimeric, can avoid the deflection of tommy bar generation any direction, guarantees safe in utilization.In addition, it also has the positioning indicating function.
Below in conjunction with accompanying drawing the utility model is further described.
