Among the figure: lock sleeve, 5.1 annular grooves, 5.2 positioning steps, 6 dustproof cushion rubbers, 7 bassoons, 7.1 locating platforms, 8 tubules, 8.1 through holes, 9 on-slip sheets, 9.1 card posts in the clamp ring on clamp ring in 1 outer locking cover, 1.1 boss, 2 times clamp rings, 2.1 male cone (strobilus masculinus)s, 2.2 grooves, 2.3 breach, 2.4 openings, 3,3.1 inner conical surfaces, 4,5.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
A kind of locking on-slip device that is used for shooting tripod pin pipe as Figure 1-3, comprise bassoon 7 and tubule 8, be provided with on-slip sheet 9 between described bassoon 7 and the tubule 8, described bassoon 7 lower end outer cover are connected to the inside and outside lock sleeve 5,1 that is threaded, and are socketed with the last clamp ring 4 that contains opening 2.4, middle clamp ring 3 and clamp ring 2 down between interior lock sleeve 5 and tubule 8 outer walls in turn.On-slip sheet 9 and tubule 8 be for seizing type is connected, and following clamp ring 2 and outer locking cover 1 are connected by the bump type structure, lock mutually by the conical surface between the upper, middle and lower clamp ring 1,3,2.
Be connected with the seizing type of tubule 8 as on-slip sheet 9 as described in Fig. 2,3, be arranged on through hole 8.1 and the corresponding card post 9.1 that is arranged on the on-slip sheet 9 on the tubule 8.As Fig. 2, shown in Figure 3, for the ease of the installation of on-slip sheet 9, described bassoon 7 inwalls are arranged with two locating platforms 7.1 longitudinally, and corresponding described on-slip sheet 9 is two and is located at locating platform 7.1 both sides respectively.
As Fig. 1, shown in Figure 3, lock sleeve 5 inside are provided with positioning step 5.2 in described, positioning step 5.2 belows are provided with inner conical surface 3.1, the outer wall of interior lock sleeve 5 is provided with outside thread, the outer wall of lock sleeve 5 outside threads top is provided with dustproof cushion rubber 6 in described, and corresponding described interior lock sleeve 5 is provided with the annular groove 5.1 that holds dustproof cushion rubber 6.The described upper and lower end of clamp ring 4 outer walls of going up is provided with male cone (strobilus masculinus) 2.1.The inwall upper and lower end of clamp ring 3 is provided with inner conical surface 3.1 in described.Described outer locking is overlapped 1 inwall and is provided with the internal thread that the outside thread with interior lock sleeve 5 matches, and the internal thread below is provided with boss 1.1.Corresponding described clamp ring 2 down is provided with associated groove 2.2, and described clamp ring 2 down is provided with male cone (strobilus masculinus) 2.1, and for the ease of installing, described the bottom of clamp ring 2 is provided with breach 2.3 down, breach 2.3 is three and uniform along the center.
Working principle of the present utility model: during rotation outer locking cover 1 locking tubule 8, middle clamp ring 3 spreading under the extruding of upper and lower clamp ring 2, and upper and lower on the contrary clamp ring 2 is tightened; When the weight on the shooting tripod was heavy more, the suffered constrictive force of upper and lower clamp ring 4,2 was just big more, thus more firm locking tubule 8, therefore have locking firmly, advantage that bearing capacity is high.On-slip sheet 9 cooperates by card post 9.1 and tubule 8 through holes 8.1, limited the length travel of tubule 8, bassoon 7 under positioning step 5.2 location of interior lock sleeve 5, limited length travel, the locating platform 7.1 of on-slip sheet 9 both sides end faces and bassoon 7 is fitted in addition, tubule 8, bassoon 7, on-slip sheet 9 threes are joined together, thereby guarantee between bassoon 7 and the tubule 8 relative rotation not to take place, and then guaranteed normally carrying out of photography operation.
The utlity model has firm locking photographic tripod pin pipe, and can improve tripod pin pipe bearing capacity, can prevent from again to relatively rotate between the bassoon 7 of tripod pin pipe and the tubule 8, therefore have advantage safe and reliable, easy to use.
Should be noted that: shooting tripod has more piece pin pipe to constitute, and the big or small 2-section pipe of being mentioned herein just is used for setting forth its structure, and the address of bassoon and tubule is also relative.
Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
