Abstract
The utility model relates to a kind of bracket locking device, by connecting body (1), termination (2) and locking section are formed, three is cylindrical body, connecting body (1) is made up of small one and large one two cylinder, less side is connected with termination (2) by attachment post (3), and both external diameters are identical, larger side is connected with locking section, locking Duan Youyi eccentric shaft (4) and end tail (5) are formed, eccentric shaft (4) is from the side in class figure-six, end tail (5) is equal with the connecting body external diameter of larger side, the defect section of figure-six eccentric shaft (4) is also equipped with a friction member (6), friction member (6) outer surface is dentation.After adopting said structure: only need rotate two arms and it just can be made to lock or unclamp, use, shrink all easily and reliable lock.
Description
Technical field
The utility model relates to a kind of support Component, refers in particular to a kind of bracket locking device.
Background technique
Existing camera, mostly support on mobile phone and fishing gear is fix by the size difference of steel pipe and stretch, cause the fastening instability of support, easily loosen, and when draw too tight time want to pack up and comparatively inconvenience, also have some to be that shortcoming is complex structure by establishing bolt to play locking function outside steel pipe, working life is short, uses also comparatively inconvenience.
Model utility content
Technical problem to be solved in the utility model is to provide a kind ofly shrinks convenience, reliable lock, support easy to use.
For solving the problem, the utility model adopts a kind of novel locking device, described locking device is by connecting body, termination and locking section are formed, three is cylindrical body, described connecting body is made up of small one and large one two cylinder, less side is connected with termination by attachment post, and both external diameters are identical, larger side is connected with locking section, described locking Duan Youyi eccentric shaft and end tail are formed, eccentric shaft is from the side in class figure-six, end tail is equal with the connecting body external diameter of larger side, the defect section of described figure-six eccentric shaft is also provided with a friction member, friction member outer surface is dentation.
As preferably, the defect section external diameter of described figure-six eccentric shaft changes from small to big.
As preferably, described friction member is circular arc.
Compared with prior art, the utility model has the advantage of: the locking device of said structure is arranged between two arms, is mixing friction member, stent collapses convenience, reliable lock, easy to use.
Accompanying drawing explanation
according to drawings and embodiments the utility model is described in further detail below.
Fig. 1 is the structural representation of a kind of bracket locking device described in the utility model.
Fig. 2 is the sectional view of Figure 1B-B section.
Fig. 3 is the plan view of Fig. 1.
Fig. 4 is using state figure of the present utility model.
As shown in Figure 1 to Figure 4,1, link; 2, termination; 3, attachment post; 4, eccentric shaft; 5, tail is held; 6, friction member; 7, arm.
Embodiment
As shown in Figure 1 to Figure 3, a kind of bracket locking device described in the utility model is made up of connecting body 1, termination 2 and locking section, three is cylindrical body, connecting body 1 is made up of small one and large one two cylinder, less side is connected with termination 2 by attachment post 3, and both external diameters are identical, larger side is connected with locking section, locking Duan Youyi eccentric shaft 4 and end tail 5 are formed, eccentric shaft 4 is from the side in class figure-six, end tail 5 is equal with the connecting body external diameter of larger side, and the defect section of figure-six eccentric shaft 4 is also equipped with a friction member 6, and friction member 6 outer surface is dentation.
Further illustrate, the defect section external diameter of figure-six eccentric shaft 4 changes from small to big.
As shown in Figure 4, friction member 6 is in circular arc.
Further illustrate, support general on market has small one and large one two arm 7 to form, the using method of locking device is, first the afterbody compared with smaller branch pipe 7 is filled in termination 2, friction member 6 is being put in the defect of eccentric shaft 4, less arm through larger arm, during locking, we screw according to the counter clockwise direction of figure-six eccentric shaft 4, because the defect section external diameter of figure-six eccentric shaft 4 changes from small to big, when being rotated counterclockwise, eccentric shaft 4 will extrude friction member 6 thus lock on larger branch pipe wall, again because friction member 6 outer surface is dentation, locking effect can be better, otherwise when we will unclamp two arms be, only need rotate according to the clockwise direction of figure-six eccentric shaft 4, make friction member 6 near larger defect portion, thus two arms are unclamped.
Further illustrate, only need rotate two arms and it just can be made to lock or unclamp, use, shrink all easily and reliable lock.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
Claims (3)
