Description

Support angle turning controller

The utility model system is relevant with the foot rest that can provide support weight, more detailed it, refer to a kind of support angle turning controller especially.

The foot rest that daily finding photography light is used, parasols reaches the foot rest that generally can support weight, though different, be more or less the same, its main deficiency is inconvenient for operation, and component parts is many and it is all inconvenient to assemble, make, and the fixed support effect is bad.

Main purpose of the present utility model, tying up to provides a kind of support angle turning controller, and it forms ease of Use with less member, and more firm support effect is provided.

The utility model provides a kind of support angle turning controller, be by establishing its seat and plural leg connects in axle pivot mode in a central principal axis lower end, and the mat positioning element cooperates spring to provide location and leg to rotate; The cylindrical all epitaxial lateral overgrowths of this pedestal are stretched the flange piece that is provided with corresponding leg quantity, and this flange piece radially wears hole and the outer end is the bead shape; This leg front end is established the joining portion of expansion, for the U-shaped shape has two sheets of picking up the ears, and forms the pivot joint slotted eye of axial external-open, in two pick up the ears the sheet front end radially run through establish hole for and relative flange bobbin pin-joint, it is characterized in that:

The Zhou Yuanshe of the flange piece of this pedestal is the engagement portion that ratchet-like is formed with predetermined number;

The joining portion central shaft of this leg is inwardly established a shrinkage pool, and establish elongated hole at least one sheet rear end of picking up the ears wherein, and this positioning element is a rectangle positioning body, radially wear hole on it, cooperate an operating bar interlock of inserting, be in an end that makes this positioning body and held by spring, and by this operating bar of start this positioning body is conflicted to locate with engaging of this base flange sheet, reach support firm, rapid operation, purpose easily.

Now lift two preferred embodiments and cooperate graphic explanation:

Fig. 1 is the sectional perspective exploded view of the utility model one preferred embodiment.

Fig. 2 is the foot rest joint sectional view of the utility model one preferred embodiment.

Fig. 3 is overall another embodiment's in the utility model joint a sectional view.

See also Figure 1 and Figure 2, a kind of support angle turning controller (10) of the utility model first embodiment, it includes one with the integrally formed pedestal of forging type (11), it is a pipe shape, be pivoted for central principal axis (19), set up three flange pieces (12a) that generally are semicircle shape (12b) (12c) in the periphery of pedestal (11) to ground, system is for cooperate articulating (13b) (13c) usefulness of three legs (13a), because three groups structure is identical, now only explain as follows with one group:

On this flange piece (12a), radially be equipped with a hole (121a), the periphery of flange butt strip (12a) is ratchet-like and forms three engagement portions (122a) (123a) (124a), and wherein engagement portion (122a) is positioned at flange piece (12a) periphery upper end and rectangular groove shape;

The joining portion (14a) of this leg (13a) front end is to enlarge to take the shape of the letter U shape and have two to pick up the ears sheet (141a) (142a), and the pivot joint that forms axial external-open is with slotted eye (143a), establish a shrinkage pool (144a) (seeing Fig. 2 (144)) in the slotted eye (143a), the tool appropriate depth, and this two sheet (141a) of picking up the ears (142a) also is the bead shape in the outer end, and radially wear hole (145a) in front end, system establishes corresponding to the hole (121a) on the flange piece (12a), wears pivot and crosses and to buckle (152a) with the C type and anchor by a pivot pin (151a); Then establish elongated hole (146a) (seeing Fig. 2 (146)) in thereafter, one pick up the ears elongated hole (146a) on the sheet (141a) is that place at operating bar (16a) center of the big width of sacrificial vessel, and with a little shank (153a) axle pivot, and the end of operating bar (16a) is inserted in the hole (171a) that this rectangle positioning body (17a) radially wears, this hole (171a) is good with microscler hole, and offer a spacing hole (172a) in the lower end of positioning body (17a), ammunition feed spring (18) is installed in the shrinkage pool (144a) of joining portion (14a), and an end holds in the spacing hole of positioning body (17a) (172a).

After above-mentioned construction device combination, see also shown in Figure 2, support angle turning controller of the present utility model, pedestal (11) is connected with pivot pin (15) axle pivot with each leg (13), be butted in arbitrary engagement portion (122) of flange piece (12) and all to be positioning body (17) front end with rectangular block shape when being in any state embed leg (13) location, spring (18) in the spacing hole of its rear end (172) then provides bearing force, not only it fastens the area of contact increase with positioning body (17) and engagement portion (122), bear strength also increases thereupon, and positioning body (17) is to be located in the axial joining portion (14) of leg (13), so can being to leg (13) along main shaft (19), the gravity that is born by central principal axis (19) top axially shares gravity, unit supports and heightens, the radial force mode of using always before being different from, so can support big gravity, and more firm, leg (13) can be not left, rock on the right side; And when rotation leg (13), only must push the front end (to the leg direction application of force) of operating bar (16) with the thumb of one hand, operating bar (16) will be a central point with shank (153), its interior end of hole (171) that is in positioning body (17) then will compress positioning body (17) downwards, the front end of pressure spring (18) positioning body (17) then breaks away from one of them engagement portion (122) (123) (124) of flange piece (12), promptly get and rotate leg (13) to predetermined angle place, behind arbitrary engagement portion (122) (123) (124), after loosening the application of force to operating bar (16), promptly the return action pushing tow positioning body (17) because of spring (18) resets, embed location, engagement portion (122), make operating bar (16) with the central shaft pivot, the pattern application of force of lever pushes positioning body (17), easy to operate, laborsaving, the defective of pulling the difficulty effort commonly used before removing.

Overall another embodiment in joint of the present utility model sees also shown in Figure 3, overall its pedestal (21) in this joint all is connected with pivot pin (25) axle pivot with each leg (23), and leg (23) location all embeds with the front end of its rectangular block shape positioning body (27) when being in any state and is butted in the arbitrary engagement portion of flange piece (22) (222), and provide bearing force by positioning body rear end spring (28), its place, engaging location area is big, the location is firm, resist mutually the engagement portion (222) that rectangle positioning body (27) and ratchet-like flange piece (22) are constituted, the mode that only embeds the flange piece top with locating stud in side commonly used before being better than certainly; And when the desire adjustment changes the height state of leg (23) or desires to fold leg (23), protrude from the two moving bars (26) of sheet (241a) outside (241b) of picking up the ears as long as pull to leg (23) direction, drive positioning body (27) front end and withdraw from engagement portion (222), get final product this leg of swing (23) to any engagement portion (222), and spring this moment (28) still is subjected to the compression of positioning body (27), after embedding arbitrary engagement portion (222), positioning body (27) just discharges compressive force to spring (28), held by the answer of spring just to be butted on engagement portion (222) to locate, and can confession leg (23) in the engagement portion (222) of the rectangle groove shape of flange piece (22) top when upwards folding this positioning body (27) be in fully in the engagement portion (222), the preferred positioning restriction effect is provided, only by a positioning body (27), spring (28) and operating bar (26), the engagement portion (222) of the periphery of mating flange sheet (22) own, the effect of multi-section type foot rest can be provided, easy to assembly, save trouble, and with low cost, support the location again firmly.
