Description

Buffer gear

Technical field

The utility model relates to a kind of buffer gear, especially relates to a kind of buffer gear for paper money case memory storage open/close lid.

Background technology

In the automatic teller machine (CRS) that paper money case is placed vertically, extract from underframe and when putting into paper money case, all must first open M transfer passage, again M transfer passage be shut after having operated.In the process of open and close M transfer passage, can impact, easily damage relevant device.

Prior art is generally used as snubber assembly by arranging air spring between M transfer passage and underframe, can play the effect of buffering, but cost is higher.

Utility model content

The technical matters that the utility model solves is, provides a kind of buffer gear that can play comfort cushioning effect and can relatively reduce costs again simultaneously.

The technical scheme that the utility model solves the problems of the technologies described above is, a kind of buffer gear is provided, for be installed on can mutually between the first component of folding, second component to play the effect of buffering, the guide pillar that this buffer gear comprises support bar, buffer spring and is arranged on second component, this support bar one end is connected with first component turnably by rotating shaft, the other end is connected with buffer spring, the guide groove of strip is set in the middle part of it, this guide pillar and the guide groove on support bar match and form slidingtype and be connected, and this buffer spring other end is fixed on second component.

Preferably, this support bar is in being inverted " L " shape, and it comprises a junction and a sliding part, and this connecting portion end is connected with first component, and the guide groove in the middle part of this support bar is arranged on this sliding part.

Preferably, this connecting portion and sliding part are 120 ° of-150 ° of angles.

Preferably, this connecting portion and sliding part are 135 ° of angles.

Preferably, this guide pillar is a riveting post.

Preferably, also comprise a pulley, this pulley is fixed on second component, and this buffer spring is wound in after on pulley and is fixed on second component.

Preferably, this second component is the casing of paper money case storage part, and this first component is the M transfer passage of paper money case storage part.

The buffer gear that the utility model provides is connected and composed by buffer spring and support bar, structure is simple, relative inexpensiveness, and during reduction along with angle closed between connected first component and second component, its cushion effect can corresponding increase, can play good buffer action.

Accompanying drawing explanation

The structural representation of a kind of buffer gear that Fig. 1 provides for the utility model one embodiment;

The partial enlargement structural representation that Fig. 2 is buffer gear shown in Fig. 1.

Embodiment

By reference to the accompanying drawings the utility model is described in further detail below by embodiment.

Refer to Fig. 1 and Fig. 2, the utility model one embodiment provides a kind of buffer gear, it is installed in paper money case storage portion 1, this paper money case storage part 1 comprises the M transfer passage 11 and casing 12 that opening and closing type setting up and down is connected, the medial surface of these relative both sides of paper money case storage part 1 is respectively arranged with a buffer gear 3, each buffer gear 3 connects M transfer passage 11 and casing 12 respectively, when M transfer passage 11 and casing 12 close, plays the effect of buffering.

This buffer gear 3 comprises support bar 33, buffer spring 35 and is arranged at riveting post on casing 12 34 and pulley 36.This support bar 33 is in being inverted " L " shape, and it comprises a junction 331 and a sliding part 332, and this connecting portion 331 and sliding part 332 are in 135 ° of angles.This connecting portion 331 end is connected by rotating shaft (non-label) turnably with M transfer passage 11.This sliding part 332 arranges strip guide groove 333, and guide groove 333 and the riveting post 34 of this strip match and form slidingtype and be connected, and make this support bar 33 rotate relative to riveting post 34 or to slide.The end of the sliding part 332 of this support bar 33 is connected with buffer spring 35 1 link, and this buffer spring 35 is around in the other end after on pulley 36 and is fixed on casing 12.

When M transfer passage 11 closes relative to casing 12, the gravity of M transfer passage 11 self is to lower compression support bar 33, support bar 33 is moved towards casing 12 by the relative sliding that is slidably connected of guide groove 333 with riveting post 34, because support bar 33 sliding part 332 is by the traction action of buffer spring 35, by the pressure of partial offset M transfer passage 11 to lower compression support bar 33, thus play buffer action, and along with the closed angle between M transfer passage 11 and casing 12 more and more less, support bar 33 moves down further, the tractive elastic force of buffer spring 35 will be larger, to be larger to the buffer action of M transfer passage 11.

In alternate embodiments, suitably increase according to the amplitude that M transfer passage 11 is opened or reduce, such as this connecting portion 331 and sliding part 332 can also be in 120 ° of-150 ° of angles; This support bar 33 also can be curved structure etc.; This buffer spring 35 can be without pulley 36, but is directly fixed on casing 12; This buffer gear 3 can also be applied on other similar devices, so that the parts connecting two mutual foldings to play buffer action.

The buffer gear 3 that the utility model provides is connected and composed by buffer spring 35 and support bar 33, structure is simple, relative inexpensiveness, and during reduction along with angle closed between connected M transfer passage 11 and casing 12, its cushion effect can corresponding increase, can play good buffer action.

Above content is in conjunction with concrete embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made.
