Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing And embodiment, this utility model is further elaborated.Should be appreciated that described herein specifically Embodiment, only in order to explain this utility model, is not used to limit this utility model.

As it is shown in figure 1, the stern fast fixing device of the joints of optical fibre according to one embodiment of this utility model 100 include tailstock 110 and the tail-hood 120 being placed on tailstock 110, and tail-hood 120 and tailstock 110 are in the inner Pivot joint is so that tail-hood 120 can rotate and free-open-close relative to tailstock 110.

The most as shown in Figure 1 to Figure 3, tail-hood 120 is main by top board 121, from the extension of top board 121 both sides Two sidewalls 122 gone out and the end plate 123 being connected to top board 121 and outer end, two side 122 are constituted.End Plate 123 is provided with the semicircle fluting 127 of accommodating covered wire cable, shown in Figure 5.Two of tail-hood 120 The inner of sidewall 122 each extends over out one and takes ear 124, takes and offers axis hole 125 and tailstock 110 on ear 124 The rotating shaft 115 of upper projection coordinates the pivot joint realizing tail-hood 120 with tailstock 110.

The most as shown in Figure 1 to Figure 3, tailstock 110 has base plate 111 and extends from base plate 111 both sides Two sidewalls 112 gone out.Being additionally provided with rubber-insulated optical cable fixing structure in tailstock 110, this is prior art, no It is protection of the present utility model point, therefore is not described in detail in this.The inner of two sidewalls 112 of tailstock 110 is convex It is provided with rotating shaft 115, in order to pivot joint tail-hood 120.Additionally, in the two of tailstock 110 sidewalls 112 one The lateral surface of sidewall is convexly equipped with button bit 113, accordingly, the corresponding sidewall of tail-hood 120 offers and this button The bayonet socket 126 that position 113 coordinates.When operator presses tail-hood 120, make tail-hood 120 by rotating shaft 115 certainly By when rotating and be pressed downward on earth, in button bit 113 card card inlet 126 so that tail-hood 120 and tailstock 110 closed-locks.The most as shown in Figure 4, the lateral surface of button bit 113 is preferably an inclined-plane 116, so It is beneficial to button bit 113 buckle in bayonet socket 126.Further, corresponding to being somebody's turn to do on the base plate 111 bottom tailstock 110 The position of button bit 113 offers avoiding hollow groove 114, and this avoiding hollow groove 114 is the most through to button bit 113 place Sidewall 112, easily opens tail-hood 120 to facilitate the finger of operator to be placed on one hand at this avoiding hollow groove 114.

Stern fast fixing device of the present utility model before use, needs tail-hood 120 is pivotally attached to tailstock 110 On.Then, operator presses tail-hood 120, makes tail-hood 120 freely rotatable by rotating shaft 115 and by downwards When being pressed onto the end, in button bit 113 card card inlet 126, it is achieved tail-hood 120 and tailstock 110 closed-lock.Open Qi Shi, singlehanded thumb is placed at the avoiding hollow groove 114 of tailstock 110, pushes out the sidewall of tail-hood 120, makes Bayonet socket 126 departs from button bit 113, the most upwards pushes tail-hood 120 open simultaneously, makes tail-hood 120 by rotating shaft 115 Rotate separation relative to tailstock 110, just can realize the light unlatching of tail-hood 120.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, All any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, all should Within being included in protection domain of the present utility model.
