Abstract
The utility model relates to a telescopic locking mechanism for a foot pipe of a tripod. The utility model is composed of a rotating shaft (1) and limited slip pieces (2), wherein, the middle of the rotating shaft (1) sags inwards to form a cam (3); the outside of the cam (3) is sheathed with the limited slip pieces (2); the insides of the two limited slip pieces (2) are provided with grooves (7); the top end of the cam (3) is matched with the inner walls of the grooves (7); the distances form the inner walls of the grooves (7) to the center of the cam (3) are from small to large; the lower part of the rotating shaft (1) is connected with a lower foot pipe together; the outsides of the lower foot pipe (5), the rotating shaft (1) and the limited slip pieces (2) are sheathed with upper foot pipes (6). The utility model has the advantages of simple structure and convenient operation.
Description
The utility model relates to a kind of telescopic locking mechanism that is used for tripod pin pipe.
At present, the pin pipe telescopic locking mechanism of the tripod on the market all adopts the tight and screw-threaded coupling of the plate padlock of traditional type, complex structure, complex operation.
The purpose of this utility model provides the telescopic locking mechanism of tripod pin pipe a kind of simple in structure, easy to operate.
The utility model is achieved by the following technical solution: it is made up of rotating shaft and on-slip sheet, the formation cam caves inward in the middle of the rotating shaft, the cam outside puts the on-slip sheet, two on-slip sheet inboards are provided with groove, match with the inwall of groove in the top of cam, the inwall of groove is ascending to the distance of cam center, and rotating shaft bottom and pin pipe link together, and is with the pin pipe in the outside of leftover bits and pieces pipe, rotating shaft and on-slip sheet.
The bottom of above-mentioned described pin pipe is provided with limited impression.
The cross section of above-mentioned described cam is " Z " shape.
Above-mentioned described two on-slip sheet inboards are provided with spacing block set.
The Placement of above-mentioned described rotating shaft bottom and leftover bits and pieces pipe is to adopt interference fit to be fixed together.
The Placement of above-mentioned described rotating shaft bottom and leftover bits and pieces pipe can link together by pin.
The above-mentioned described afterbody of going up the pin pipe is with the guiding cushion rubber, and guiding cushion rubber the inside is with the pipe of getting a foothold.
The utility model compared with prior art has following advantage: unclamp cam, on-slip chip architecture as long as rotate the leftover bits and pieces pipe, just can regulate relatively moving of leftover bits and pieces pipe, when moving to suitable position, counter-rotating is got a foothold to manage and just can be locked, the pipe of getting a foothold is no longer relatively moved, simple in structure, easy to operate.
Below in conjunction with accompanying drawing the utility model is done detailed explanation:
Fig. 1 is a structure erection drawing of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the another kind of phase diagram of Fig. 2;
Fig. 4 is an explosive view of the present utility model;
Fig. 5 is the utility model embodiment 1 a erection drawing;
Fig. 6 is the utility model embodiment 1 a explosive view;
Fig. 7 is the utility model rotating shaft and the another kind of connection diagram of pipe of getting a foothold.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model is made up of rotating shaft (1) and on-slip sheet (2), cave inward in the middle of the rotating shaft (1) and form cam (3), cam (3) outside puts on-slip sheet (2), two on-slip sheet (2) inboards are provided with groove (7), match with the inwall of groove (7) in the top of cam (3), the inwall of groove (7) is ascending to the distance at cam (3) center, rotating shaft (1) bottom links together with the pipe (5) of getting a foothold, and is with pin pipe (6) in the outside of get a foothold pipe (5), rotating shaft (1) and on-slip sheet (2).The bottom of last pin pipe (6) is provided with limited impression (8), and it mainly acts on is the distance that restriction leftover bits and pieces pipe (5) and last pin pipe (6) relatively move.Two on-slip sheet (2) inboards are provided with spacing block set (9), and it mainly acts on the angle of the swing that is restriction cam (3).Afterbody at last pin pipe (6) is with guiding cushion rubber (10) in addition, and guiding cushion rubber (10) the inside is with the pipe (5) of getting a foothold, and the main effect of guiding cushion rubber (10) play the guiding role to pipe the mobile of (5) of getting a foothold.
Rotating shaft in addition (1) bottom can adopt interference fit to be fixed together with the Placement of managing (5) of getting a foothold, and punching press together during assembling.As shown in Figure 7, rotating shaft (1) bottom also can link together by pin (4) with the Placement of the pipe (5) of getting a foothold.
As Fig. 5, shown in Figure 6, the utility model is applied on the pin of tripod on three pin pipes, the effective the utility model of adjacent pin connects.
Working principle of the present utility model is as follows: as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, clockwise rotate the pipe (5) of getting a foothold, the pipe (5) of getting a foothold drives rotating shaft (1) and rotates, the cam (3) at rotating shaft (1) middle part promotes two on-slip sheets (2) and expands outwardly, the tube wall of the skin of two on-slip sheets (2) and last pin pipe (6) is close together, and at this time, cam (3) is just in time on the top of the inboard groove (7) of on-slip sheet (2), last pin (6) and following pin (5) locking can not be moved; Rotate counterclockwise rotating shaft (1), make the cam (3) at rotating shaft (1) middle part that two on-slip sheets (2) are expanded outwardly, at this time go up pin (6) and can relatively move with following pin (5).
