The caging mechanism includes an expansion body (7), a nut (8) and a connection part (9), and the expansion body (7), the nut (8) are in the upper jacket tube (4), the connection part (9) is mounted at the top of the lower jacket tube (5), the expansion body (7) is between the connection part (9) and the nut (8), a protuberant screw rod (10) getting across the through-hole (11) of the expansion body (7) and having a threaded connection with the nut (8) is fixed at the top of the connection part (9). The utility is of a simple structure, is easy for manufacturing, and is convenient for use and the tubes are not easy to be deformed.
Description
1, technical field:
The utility model relates to a kind of camera trivets by rotary extension pin pipe
2, background technology:
The mechanism of traditional camera trivets telescopic leg pipe starts by spanner, this telescopic leg pipe mechanism more complicated, trouble is installed, the manufacturing cost height, in order to cater to telescopic leg pipe mechanism, pin tube section shape can not cause circle, cross sectional shape is complicated, when telescopic leg pipe mechanism works, pin pipe easy deformation is arranged in stressed bigger.
3, summary of the invention:
A kind of camera trivets by rotary extension pin pipe of the utility model, it is simple in structure, installs easy to manufacturely, easy to operate, and the pin pipe is not yielding.
The utility model is achieved by the following technical solution:
A kind of camera trivets by rotary extension pin pipe, comprise The Cloud Terrace, elevating lever, article three, pin pipe, wherein the pin pipe is made up of the sleeve pipe of more piece different tube diameters, adjacent sleeve pipe up and down nests together, and adjacent installation one flexible locking mechanism between the sleeve pipe up and down, should comprise an expander by flexible locking mechanism, a nut and a web member, this expander and nut are positioned at sleeve pipe, web member is installed in the running casing top, expander is between web member and nut, the web member top is protruding with screw rod, and screw rod passes the through hole of expander and is threaded with nut.
Above-mentioned described expander is the cylindrical colloid of a high resiliency, high rigidity.
Above-mentioned described expander top is provided with shroud, and shroud is bundled in the expander top to nut.
Above-mentioned described nut is a taper shape, and the nut bottom is embedded into the through hole the inside of expander.
The middle part of above-mentioned described screw rod is protruding with flank, and flank is embedded into the groove that is positioned at the through hole middle part of expander.
The above-mentioned described sleeve bottom outside of going up is equipped with the pipe overcoat.
The above-mentioned described inwall of going up sleeve pipe is protruding with fixture block, and fixture block is embedded into the draw-in groove the inside of expander.
The utility model compared with prior art has following advantage: 1) by the sleeve pipe in three pin pipes of rotation, can quick-expansion or lock three pin pipes, simple to operation, and the power that three pin pipes after the locking can support is bigger, and the braking-force ratio that promptly flexible locking mechanism produces is bigger; 2) flexible locking mechanism is simple in structure, installs easy to manufacturely, and cost is low; 3) the pin pipe is not yielding, and the last sleeve pipe length nested with running casing can be selected arbitrarily, and is unrestricted, and promptly the height of leg is regulated arbitrarily within a certain height.
4, description of drawings:
Below in conjunction with accompanying drawing the utility model is done detailed explanation:
Fig. 1 is the utility model stereographic map;
Fig. 2 is the structural representation of flexible locking mechanism between the sleeve pipe of the present utility model;
Fig. 3 is the A-A cut-open view of Fig. 2;
Fig. 4 is the B-B enlarged drawing of Fig. 3.
5, embodiment:
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model comprises The Cloud Terrace 1, elevating lever 2, article three, pin pipe 3, wherein pin pipe 3 is made up of the sleeve pipe of more piece different tube diameters, adjacent sleeve pipe up and down 4,5 nest together, and adjacent sleeve pipe up and down 4, one flexible locking mechanism is installed between 5, it is characterized in that: this flexible locking mechanism comprises an expander 7, a nut 8 and a web member 9, this expander 7 and nut 8 are positioned at sleeve pipe 4, web member 9 is installed in running casing 5 tops, expander 7 is between web member 9 and nut 8, web member 9 tops are protruding with screw rod 10, and screw rod 10 passes the through hole 11 of expander 7 and is threaded with nut 8.Expander 7 is cylindrical colloids of a high resiliency, high rigidity.Expander 7 tops are provided with shroud 12, and shroud 12 is bundled in expander 7 tops to nut 8.Nut 8 is a taper shape, and nut 8 bottoms are embedded into through hole 11 the insides of expander 7.The middle part of screw rod 10 is protruding with flank 13, and flank 13 is embedded into the groove 14 that is positioned at through hole 11 middle parts of expander 7, and 4 outsides are equipped with pipe overcoat 6 at the bottom of the last sleeve pipe.The inwall of last sleeve pipe 4 is protruding with fixture block 15, and fixture block 15 is embedded into draw-in groove 16 the insides of expander, and expander 7 can not be rotated.
Principle of work of the present utility model is: running casing 5 turns clockwise, running casing 5 drives web member 9 and web member 9 top screw rods 10 rotate together, nut 8 screw rod 10 that slips away gradually, the middle part of nut 8 and screw rod 10 is protruding with between the flank 13 apart from widening, expander 7 radially bounces back, thereby no longer sleeve pipe 4 inwalls are gone up in compressing, therefore friction force is very little between expander 7 outside surfaces and last sleeve pipe 4 inwalls, and running casing 5 drives web member 9, expander 7 and a nut 8 and together is retracted in the sleeve pipe 4.When arriving a certain position, can be rotated counterclockwise running casing 5, running casing 5 drives web member 9 and web member 9 top screw rods 10 rotate together, nut 8 slides into screw rod 10 gradually, the middle part of nut 8 and screw rod 10 is protruding with between the flank 13 apart from dwindling, under flank 13 effects at the middle part of nut 8 and screw rod 10, expander 7 radially opens, thereby sleeve pipe 4 inwalls are gone up in expander 7 compressings, therefore friction force is very big between expander 7 outside surfaces and last sleeve pipe 4 inwalls, running casing 5 is lockable, and can not move along last sleeve pipe 4.
