Detailed description of the invention
Below by specific embodiment, a kind of stretching bar fast replacing device described in the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of stretching bar fast replacing device, comprise a fixing locating rack 1, be provided with screwed hole 2 in described locating rack 1, be provided with thread spindle 3 in screwed hole 2, the top of thread spindle 3 is provided with external screw thread 4, thread spindle 3 is threaded with locating rack 1 mutually by upper external screw thread 4, described thread spindle 3 is hollow structure, and stretching bar 5 is located in thread spindle 3, and locks with thread spindle 3 phase.
Preferably, as shown in Figure 1 and Figure 2, latch-up structure between described thread spindle 3 and stretching bar 5 is: thread spindle 3 is made up of the semiaxis that two panels is mutually involutory, the bottom of thread spindle 3 is provided with lower external screw thread 6, the bottom of thread spindle 3 is provided with thread bush 7, and thread bush 7 is threaded with thread spindle 3 mutually by screw thread.The bottom of described thread spindle 3 is taper 8, and the bottom of described thread bush 7 is the pyramidal structure matched with the taper 8 of thread spindle 3.When screwing thread bush 7, thread bush 7 moves from below to up, under the effect of the conical surface, the bottom of thread spindle 3 is progressively tightened up, thus is locked in firmly in thread spindle 3 by stretching bar 5.
Preferably, as shown in Figure 1, be provided with one section of thin segment 9 in the part that described stretching bar 5 is connected with thread spindle 3, position corresponding with thin segment 9 on thread spindle 3 is provided with protuberance 10.By the retaining structure of protuberance 10, ensure that stretching bar 5 is locked in thread spindle 3 reliably further.
Preferably, as shown in Figure 1, the upper external of described thread spindle 3 is provided with locking nut 11, and locking nut 11 is threaded mutually with thread spindle 3.By locking nut 11, both achieve the locking on thread spindle 3 top, achieve again thread spindle 3 position spacing in the screwed hole 2 of locating rack 1.
Preferably, as shown in Figure 1, the middle part of described thread spindle 3 is provided with the plat part 12 matched with spanner.Turn plat part 12 realizing thread spindle 3 can be clamped in by spanner.
Operation principle of the present utility model is: when the height difference of the bottle changed required in bottle blowing machine is little, can by unclamping locking nut 11, the height and position of thread spindle 3 in locating rack 1 is regulated to regulate the height and position of stretching bar 5, realize the fine setting of stretching bar 5 height, thus stretching bar 5 can be changed.When stretching bar 5 changed by needs, unclamp locking nut 11, thread spindle 3 is screwed out from the screwed hole 2 of locating rack 1, then locking nut 11 and thread bush 7 are screwed off from thread spindle 3, thus thread spindle 3 can be divided into two, and then stretching bar 5 can be taken out from thread spindle 3, realize changing.
The above embodiments are the principle of illustrative the invention and effect thereof only, and the embodiment that part is used, but not for limiting the utility model; It should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
