Detailed description of the invention
In FIG, a kind of locking device of tent pole, it comprises outer bar 1 and interior bar 6, and interior bar 6 is assemblied in the inner chamber of outer bar 1.In the present embodiment, outer bar 1 and interior bar 6 all adopt commercially available aluminium alloy extruded shaping pipe.
In FIG, the present invention also comprises a locking cover 4.
As shown in Figure 2, lock cover 4 to be made up of body 401, hinged seat 402 and locking bed 403.Locking cover 4 can be welded by the body 401 of metal, hinged seat 402 and locking bed 403, and other materials also can be adopted to make.In the present embodiment, locking cover 4 selects conventional ABS plastic material shaping through a Shooting Technique.
As shown in Figure 1 and Figure 2, coaxially throughly on body 401 offer bar chamber 405 and an outer bar chamber 404 in stair-stepping one, outer bar 1 is plugged in outer bar chamber 404, and interior bar 6 is stretched out by interior bar chamber 405.
Conveniently outer bar 1 inserts outer bar chamber 404, realizes the locking of the external bar 1 of locking cover 4, as shown in Figure 1 and Figure 2, the body 401 in the outer bar chamber 404 of correspondence axially offers an expansion seam 14, locking bed 403 fork-shaped splits on the body 401 of expansion seam 14 both sides, and locking bed 403 tension makes body 401 be locked outside on bar 1 by locking member 13.
Locking member 13 can adopt lock bolt and the nut of threaded engagement, also can adopt tapping screw.In the present embodiment, locking member 13 preferentially adopts lock bolt and nut.As shown in Figure 1, locking bed 403 has counter sink 3, be serially connected in lock bolt in locking bed 403 both sides counter sink 3 and nut and strain locking bed 403 and body 401 is locked outside on bar 1.
As shown in Figure 1 and Figure 2, in corresponding bar chamber 405 body 401 on offer the clamping block chamber 8 in bar chamber 405 in a connection, hinged seat 402 fork-shaped splits on the body 401 of both sides, clamping block chamber 8.
In FIG, spanner 10 is made into integration by spinning cam 1001 and handle 1002, and spinning cam 1001 and hinged seat 402 are hinged.
In FIG, clamping block 7 is slidably fitted in the clamping block chamber 8 on body 401, and the circumferential surface of one end and interior bar 6 is tangent, and the outer rim of the spinning cam 1001 of other end and spanner 10 is tangent.
As shown in Figure 1, on the handle 1002 of corresponding locking bed 403, fork-shaped is provided with lockplate 11, and the medial surface of lockplate 11 is provided with locking projections 12, and on the lateral surface of locking bed 403, correspondence is provided with latch recess 2.When support bar is in the lock state, the locking projections 12 on handle 1002 slides in the latch recess 2 on locking bed 403, now spanner 10 not easily autorotation, ensures use safety.
In order to limit the glide direction of clamping block 7 in clamping block chamber 8, as shown in Figure 1 and Figure 2, a guide limiting stopper 5 is provided with in the bottom in clamping block chamber 8.In FIG, on clamping block 7, corresponding guide limiting stopper 5 is provided with a guide and limit groove 9.
Bar in support bar 6 and outer bar 1 in use, to be serially connected in locking cover 4 in bar chamber 405 and outer bar chamber 404, to screw the bolt on locking bed 403, make body 401 be fixed on outer bar 1 by the present invention respectively; Interior bar pull is stretched over precalculated position, rotating spanner 10, spinning cam 1001 synchronous axial system, clamping block 7 slides along the inside bar 6 in clamping block chamber 8 under the promotion of spinning cam 1001, and spinning cam 1001 wheel rim promotes clamping block 7 end face and contacts with interior bar 6 circumferential surface in interior bar chamber 405; Be rotated further spanner 10, spinning cam 1001 is oppressed clamping block 7 and is compressed with interior bar 6, the locking position of bar 6 and outer bar 1 in realizing; When interior bar need bounce back, negative side's rotary spanner 10, clamping block 7 no longer internally bar 6 compresses, and now convenient for interior bar 6 contraction is got back in the inner chamber of outer bar 1.
Structure of the present invention is simple, reasonable in design, difficulty of processing is little, easy to use and reliable.
