Description

Rent and sell quick-witted anti-rock supporter

Technical Field

The invention relates to the field of machinery, in particular to an anti-shaking commodity shelf for a renting and selling machine.

Background

Chinese patent 2019205126324 is a new type of circulating mobile bookshelf type book-selling machine applied by the applicant at 2019, 04, month 16, which includes a circulating bookshelf, and does not solve the problem of the bookshelf shaking caused by the gravity center shift.

Chinese patent 2019205126343 is a cyclic storage rack that applicant applied in 2019, 16/04, wherein the problem of preventing the object placing table from shaking due to gravity center shift is solved by using a guide rail, and it is a simpler structure to set the guide rail to limit the moving track to avoid shaking, but when the arc is bent, the set guide rail may affect other parts, for example: the setting is difficult to fix in the sprocket inboard, sets up and can block to put the thing platform operation in sprocket outside chain.

The Chinese patent 2019107620671 of the applicant discloses a steady type circulation supporter, comprising a frame body, the frame body both sides are provided with first group sprocket and second group sprocket, be provided with the chain on every group sprocket, it is provided with the horizontal pole to rotate between the corresponding position of two chains, be provided with on the horizontal pole and put the thing platform, it puts thing platform focus and horizontal pole focus on a vertical face, a serial communication port, be provided with first guide way and second guide way on the frame body, first guide way and second guide way comprise the semi-circular arc groove at both ends and middle vertical groove, the horizontal pole both ends are fixed with first positioning mechanism and second positioning mechanism respectively, first positioning mechanism cooperatees with first guide way. The invention prevents the problem of shaking of the object placing table caused by gravity center shift, is easy to be installed on the shelf body and has no influence on other mechanisms of the circulating object placing shelf. The above problem is solved, but it requires high machining accuracy, otherwise slight shaking is still generated in the arc-shaped rail. And, because the locating arm direct mount is on the chain, it is less to cross the radius, needs very big interval between the goods basket, otherwise the goods basket can influence each other when crossing the bend, can't cross the bend.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: provides an anti-shaking commodity shelf for a renting and selling machine.

The utility model provides a rent and sell quick-witted anti-rock supporter, comprising a frame body, the support body both sides are provided with two sets of sprockets, be provided with the chain on every group sprocket, two sets of sprocket outsides are provided with first guide way and second guide way respectively, first guide way and second guide way are by the semicircle groove, smooth transition arc groove and vertical groove are constituteed, the semicircle groove is located both ends, vertical groove component is located the middle part, smooth transition arc groove is located between semicircle groove and the vertical groove, the semicircle groove center of first guide way and second guide way is eccentric about with the sprocket center is eccentric about with respectively, the eccentricity is X, the rotatable suspension that is provided with on the chain, the rotatable locating arm that is provided with on the suspension, the locating arm tip is provided with the leading wheel, the leading wheel matches with first guide way and second guide way, locating arm length is X, two corresponding locating arm mutually perpendicular.

Furthermore, the suspension is a herringbone frame, the herringbone frame comprises a first arm and a second arm, one end of the first arm and one end of the second arm are respectively and rotatably arranged on the chain, and the other end of the first arm and the other end of the second arm are rotatably arranged on the positioning arm.

Furthermore, a lug is fixed on the positioning arm and penetrates through the propeller strut.

Further, the leading wheel is PA wheel or PU wheel.

Compared with the prior art, the invention has the following beneficial effects:

the invention prevents the problem of shaking of the object placing table caused by gravity center shift, is easy to be installed on the shelf body and has no influence on other mechanisms of the circulating object placing shelf.

The invention adopts the left and right eccentric guide rails and the upper and lower eccentric guide rails, the two positioning arms are respectively arranged in 90 degrees, under the condition that the gravity center of the object placing table is deviated, the force generated by the shaking trend of the object placing table is vertical to the guide groove through at least one of the positioning arms, and the stability is very high.

The herringbone frame effectively increases the over-bending radius, so that more goods baskets can be hung, and the design of the herringbone frame is more stable.

Drawings

FIGS. 1-4 are schematic views of the structure of the present invention.

Fig. 5-7 are enlarged views of this section.

In the figure: the support body 1, sprocket 2, first guide way 3, second guide way 4, chain 5, propeller strut 6, location arm 7, leading wheel 8, lug 9, basket 10.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
