Abstract

The utility model discloses a stand with a pin folding fixing base, which comprises a base, a pin hinged under the base, a table connected with optical device, and a middle tube through the base and supporting the table, wherein the lower end of the middle tube is arranged with a flat fixing base, the portion of the fixing base towards the pin is arranged with a relative open clamp slot which size is engaged with the diameter of the pin, to form clamp engagement. The utility model can effectively utilize the space between pins, and reduce the folded space of the stand, with high strength, stable folding process, simple application, portable property and easy storage or the like.

Description

A kind of foot rest that folds fixed base with pin

Technical field

The utility model relates to the foot rest structure that optical equipment supports usefulness, particularly with the fixing structure of pin constraint.

Background technique

Traditional optical equipment supporting tripods, constitute the location of pin opens support that the folding supporting element of umbrella wherein is primarily aimed at foot rest when using and fixing by the folding supporting element of the middle pipe of pedestal, The Cloud Terrace, connection pedestal and The Cloud Terrace, many pins that are loaded on the pedestal bottom and the umbrella between the middle tube and tube pin.And when being in the collapse state of non-use for foot rest, general not constraint between each pin, thereby pin often opens easily voluntarily, causes to take up room, it is very inconvenient to carry.The fixed constraint problem when pin folds has been ignored in traditional foot rest design just.

The model utility content

The effective problem of fixed constraint when the utility model folds at traditional foot rest, the special proposition a kind ofly folds the foot rest of fixed base with pin, and it is little to take up room after pin is folded, and structural strength is good, is simple and easy to usefulness, and is easy to carry.

The technical solution of the utility model is: a kind of foot rest that folds fixed base with pin, include pedestal, be articulated in the pin of pedestal below, the The Cloud Terrace that is connected with optical equipment, pass the middle pipe of pedestal and supporting The Cloud Terrace, the fixed base of a flat is equipped with in the underpart of middle pipe, the corresponding outwardly pin of fixed base place has the opening draw-in groove, the size of opening draw-in groove and the diameter of pin coupling, and formation is clasped.Further, the opening draw-in groove semicircular in shape on the fixed base divides three equal parts to be symmetrically distributed along the center of fixed base.And middle pipe is the section bar that cross section is symmetry " people " font, and its three smooth inner concave arc surfaces are respectively over against three pins.

Such structure has tangible advantage:

1, fixed base is located between the pin dexterously, makes full use of the space between the pin, and it is littler than like product to make pin fold the back overall dimensions, and structural strength will be got well;

2, pin can directly be snapped in the opening draw-in groove of fixed base, is simple and easy to usefulness, folding with convenience;

3, pin folds the back fixed base and can make it to fixedly positioning, and is difficult for unclamping, and carries, seasoning is convenient.

Embodiment

Referring to Fig. 1-Fig. 5, the foot rest of present embodiment mainly is made of The Cloud Terrace 1, pedestal 2, pin 3 and middle pipe 4, and three pins 3 are symmetrically distributed and are articulated in pedestal 2 belows, and middle pipe 4 passes pedestal 2 and installs, and its top is equipped with The Cloud Terrace 1.The fixed base 5 of a flat is equipped with in pipe 4 underpart in being with other difference, on the fixed base 5 by center three equal parts corresponding three the opening draw-in grooves 51 that have that are symmetrically distributed with three pins 3, opening draw-in groove 51 semicirculars in shape, its size is corresponding with the diameter of pin 3, can form to be clasped.When foot rest was in user mode and opens, each pin 3 broke away from fixed bases 5, and fixed base 5 is inoperative; When each pin 3 will fold when carrying or placing, each pin 3 inwardly draws in, and is snapped in the opening draw-in groove 51 of fixed base 5, and opening draw-in groove 51 utilizes interference fit that pin 3 is blocked the location, thereby makes pin 3 restrained.Further, occupation space when folding in order to save pin 3, the shape-designing of middle pipe 4 becomes the solid profile (as shown in Figure 5) of symmetry " people " font, be formed with three smooth inner concave arc surfaces 41 above it, three inner concave arc surfaces 41 are just in time identical with the cylndrical surface of three pins 3, thereby make pin 3 fold compactlyer, and be difficult for getting loose.

Claims

1, a kind of foot rest that folds fixed base with pin, include pedestal, be articulated in the pin of pedestal below, the The Cloud Terrace that is connected with optical equipment, pass the middle pipe of pedestal and supporting The Cloud Terrace, it is characterized in that: the fixed base of a flat is equipped with in the underpart of middle pipe, the corresponding outwardly pin of fixed base place has the opening draw-in groove, the size of opening draw-in groove and the diameter of pin coupling, and formation is clasped.

2, foot rest according to claim 1 is characterized in that the opening draw-in groove semicircular in shape on the fixed base, divides three equal parts to be symmetrically distributed along the center of fixed base.

3, foot rest according to claim 1 is managed the section bar that is symmetry " people " font for cross section in it is characterized in that, its three smooth inner concave arc surfaces are respectively over against three pins.
