Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2, Fig. 4 and shown in Figure 5, the middle pipe of a kind of tripod of the utility model shrinks, development mechanism, and it comprises: middle pipe 10, lock ball 20, helmet assembly 30, knob 40, shell fragment 50 and end plug 60.
Described lock ball 20 is used for encircling pipe from the outside, described lock ball comprises symmetrically arranged lock ball left side halfbody 21 and the right halfbody 22 of lock ball, convex with a drive-connecting shaft 23 on the sidewall of the left and right halfbody of described lock ball, described lock ball left side halfbody and the right halfbody of lock ball are separate structure.
As Fig. 2, shown in Figure 4, described helmet assembly 30 comprises last helmet body 31 and the following helmet body 32 that is interlocked, on preventing, following helmet body breaks away from, both connect by screw 33, on, following helmet body fastens the back and forms disc structure, on, its middle cavity 34 that is used for ccontaining described lock ball that is formed with of following helmet body combination back, described lock ball can be around drive-connecting shaft last, 180 ° of rotations are upwards done in the below, the madial wall of described cavity is provided with the drive-connecting shaft containing hole (not shown) that is complementary with described drive-connecting shaft, and this containing hole is by last, groove (not shown) on the following helmet body is put together; One side of described cavity is provided with an opening 35 that communicates with the external world, and pipe 10 passed through during this opening 35 can supply.All extend two articulated sections 36 on three directions of the described periphery of helmet body down, the end of described pin pipe is provided with the protuberance 37 that is complementary with described articulated section, and described protuberance is articulated in the middle of two articulated sections 36 rotationally by bearing pin.
Described knob 40 is plugged on the described helmet assembly 30, and the end of the knob in the insertion helmet assembly contacts mutually with described lock ball.
