Abstract

The utility model discloses a stepless variable bracket, comprising a vertical rod and a transverse rod which are connected by a connecting piece. The vertical rod is made into a groove shape, and the transverse rod is made into an H shape, and the connecting piece is provided with a vertical rod fixing rod a transverse rod fixing rod of which the middles are alternately provided with a plurality of convex tables, the convex tables of the vertical rod fixing rod are also provided with convex edges capable of being inserted to the groove hole of the transverse rod and being slid in the groove hole, and a T shape convex post is obliquely and outward extended out of the vertical rod fixing rod. The transverse rod of the utility model can vary the position of the bracket through stepless, having convenient and quick use, and the integral bracket has simple manufacture, strong interchangeability, compact structure and beautiful appearance.

Description

Stepless variable bracket

The utility model relates to a kind of carriage of shelf, especially relates to a kind of self adjustable carriage.

No matter be that family expenses or commercial use and carriage are made with timber or metal mostly at present, wherein a montant is fixing on the wall or on other fixtures, another cross bar meets at right angles with montant and is connected, the shelf that is placed on it in order to supporting, also available bar diagonal brace triangularity between montant and cross bar, structure is more perfect, firm.The shortcoming of this carriage is that the position of shelf can not regulated at will, though a kind of cross bar upper-lower position of regulating is arranged now, it can only have level to regulate on fixing several position, can't reach step-less adjustment; In addition, this carriage outward appearance is heavy, coarse, is not suitable for the usefulness with commercial decoration of beautifying of Modern Family.

The purpose of this utility model is by the mechanism that uses chute to combine with slide block, realizes the step-less adjustment of carriage cross bar; By positioning piece cross bar can be located at an arbitrary position.

The utility model is a kind of infinitely variable carriage, and it has a montant and cross bar, and described montant links to each other with a connection piece with cross bar; Described montant is made groove shape, described cross bar is made H shape, described connector has vertical stick holding rod and the cross bar holding rod that a midfeather is provided with a plurality of boss, the width of described boss is respectively less than montant and cross bar width of rebate, montant and cross bar can insert fixed bar and reach the location like this, can insert the flange of cross bar slotted eye and slippage therein on the boss of described cross bar holding rod in addition, so that cross bar is fused with cross bar holding rod securely, an oblique protruding T shape projection on the described vertical stick holding rod, described connector can be located on the optional position of montant, described T shape projection bottom is the cylinder of a diameter less than montant notch size, top be essentially a diameter greater than montant notch size but radius less than the semicylinder of montant notch size.

The utility model has the advantages that its position of carriage cross bar energy step-less adjustment, easy to use, regulate simple to operate, rapid; Montant and cross bar are blocked by the hot-drawn section bar and make, and connector is directly cast gained, so whole carriage is easy to manufacture and interchangeability is strong; The carriage moulding is succinct, and is elegant in appearance.

Below in conjunction with accompanying drawing the utility model most preferred embodiment is described in detail.

Fig. 1 is the positive view of the utility model most preferred embodiment;

Fig. 2 be among Fig. 1 " A-A " to cutaway view;

Fig. 3 be among Fig. 1 " B-B " to cutaway view;

Fig. 4 is the assembling schematic diagram of the utility model most preferred embodiment.

Referring to Fig. 1, Fig. 2 and Fig. 3, montant 1 and cross bar 3 are by aluminium alloy hot-drawn moulding at high temperature.Montant 1 is made groove shape, its notch two sidewalls inwardly turn down about 90 ° relatively and form side wall ledge 12, nearly bottom land place two sidewalls are to central authorities' pointed one-tenth projection body 11 in the groove, offer two through holes 19 and tread plate 2 made from flexible materials such as rubber, plastics of groove inner bottom part embedding at interval at montant 1 bottom land, tread plate 2 is clamped by projection body 11.Cross bar 3 is made H shape, and its two opening part two sidewalls are inwardly all distinguished turnover relatively and formed flange 13,14 for about 90 °; Be embedded with in flange 13 middle openings with what rubber, plastic or other material were made and put bar 4, make the shelf (not drawing among the figure) that rests on the cross bar 3 can stablize placement; And cross bar 3 one ends also are embedded with a block 5, can prevent that shelf from vertically moving along cross bar 3 on the one hand, also play the effect that beautifies on the other hand.

Montant 1 links to each other with cross bar 3 usefulness a connection piece 6, connector 6 is triangular in shape, it has vertical stick holding rod 9 and the cross bar holding rod 7 that a midfeather is provided with two boss, also two boss can be linked to be a vertical raised line, wherein the width of boss is respectively less than the width of 14 of 12 of montant flanges and cross bar flanges.Can insert the flange 8 of cross bar slotted eye 16 and slippage therein on cross bar holding rod 7 boss in addition, there is an oblique protruding T shape projection 10 vertical stick holding rod 9 upper ends or optional position, projection 10 bottoms are a cylinder, top is essentially the notch size of the diameter of semicylinder semicylinder greater than montant 1, radius is then less than the notch size, so that after packing into, can block on cell wall and a flange 17 and 18, can be placed in the notch of montant 1, making can be along parallel sliding about the notch flange with sliding.Two fixed bars, 7,9 usefulness reinforcements 15 are strengthened connecting.

Obviously, cross bar 3 also can be made into roughly just as the groove shape of montant 1, offers two through holes at interval at cross bar 3 bottom lands, is packed with what rubber, plastics etc. was made and puts piece, as small sucker or nahlock, replaces putting bar 4 and places shelf thereon.In addition, the top of T shape projection 10 also can be made into rectangular body, and its length is greater than montant notch size, but width is less than montant notch size.

Referring to Fig. 4, during use, montant 1 is fixing on the wall or on other fixtures with screw by through hole 19, fill in tread plate 2, T shape projection 10 on the connector 6 is put at a certain angle the groove of montant 1, turn over an angle again the upper end of projection 10 is blocked by the flange 12 of montant 1 and tread plate 2, it can not be moved up and down, then cross bar 3 is inserted cross bar holding rod 7 by the arrow C direction.When the height of cross bar 3 need be regulated, only need connector 6 is stuck up an angle by arrow D is outer in the other direction, make projection 10 upper ends break away from tread plate 2, can in montant 1 groove, move up and down connector 6, reaching when needing the position, getting final product after connector 6 is resetted by arrow D direction.
