Abstract
Disclosed is an adjustable braking system device used in a shopping trolley, which relates to the vehicle braking technology and is characterized in that a pull rod (6) fixed on a medial shaft (7); the pull rod (6) drives a first brake (3) through a fourth transmission rod (11); the pull rod (6) is linked with a second transmission rod (9) positioned at the a wheel axel (2) through a first transmission rod (8) and drives a second brake (12) through a third transmission rod (10); the using method includes that A. when the shopping trolley (5) is in the braking state in a slope-shaped elevator (4), the pull rod (6) is pulled from the turn-on area to the turn-off area manually to withdraw the braking state; B. when the user pushes the shopping trolley (5) to an ideal position in the slope-shaped elevator (4), the pull rod (6) is pulled from the turn-off area to the turn-on to enable the trolley to be in the braking state.
Description
Technical field:
The present invention relates to automobile-used braking technology.
Background technology:
All appreciable hand-push shopping cart in big-and-middle-sized supermarket, its brake system is fixing, when hand-push shopping cart is located at up and down in the domatic elevator, because trolley wheel and brake equipment thereof make hand barrow be in automatic braking mode with automatic coupling of domatic elevator.Again to return original floor shopping impossible when people want to spur it on the domatic elevator.For example: client is after having shifted hand barrow onto domatic elevator downstairs after the shopping of the 3rd buildings, when thinking to turn back to again the 3rd buildings and augmenting some commodity again, impossible, be in braking mode because be arranged in the brake equipment of the hand barrow on the domatic elevator, again after returning the 3rd buildings again after having only downstairs, just can augment the commodity in the 3rd buildings, this trouble that is caused by the hand barrow prior art is bothersome.---brought very big inconvenience to client.
Summary of the invention:
The present invention's purpose:
A kind of improvement design plan that proposes in order to address the above problem exactly to existing hand-cart brake system.
In order to realize goal of the invention, intend adopting following technology:
Structure of the present invention:
It comprises that its end is positioned at the drg on the wheel shaft of rear portion;
It is characterized in that:
It comprises the pull bar that is positioned on the axis, and is positioned at second drive link on the anterior wheel shaft; The bottom of pull bar is connected in the middle part of first drg by the 4th drive link, be positioned at pull bar and be connected with the upper end of second drive link to first drive link between the pull bar upper extreme point with the axis point of connection, the bottom of second drive link is connected with the middle part of second drg on being positioned at anterior wheel shaft by the 3rd drive link.
Using method of the present invention:
A. on the domatic elevator, be in braking mode when hand-push shopping cart, and the user is when needing to cancel this braking mode this moment, just by manually pull bar being pulled to pass closed region (braking elimination state of the present invention) by opening the zone;
B. on the domatic elevator, hand-push shopping cart is pushed ideal position as the user, when allowing hand-push shopping cart be in static braking mode, just be pulled to and open regional (braking mode of the present invention) by closing closed region by pulling moving pull bar.
The present invention's maximum characteristics compared with the prior art are:
Because the present invention is provided with the control and regulation system that whether drg is carried out braking function,---prior art does not exist drg work whether control and regulation function.---for the user who uses hand-push shopping cart can allow hand barrow or advance or brake at any time, especially the two end portions at the domatic elevator also can allow it be in braking mode or travel condition by user's control at any time, obviously, once after the user shifts hand barrow onto domatic elevator two end positions up and down, in the time of need leaving the domatic elevator and return to the market shopping of original floor, (this is that prior art can't realize just needn't to worry can not to recover travel condition again by hand barrow.---trolley wheel is trapped in the step groove of domatic elevator and can't advances again).
Description of drawings:
Fig. 1 illustrates prior art constructions.
Fig. 2 is that the K of Fig. 1 is to detail drawing (wheel part).
Fig. 3 has illustrated the structure of braking mode of the present invention.
Fig. 4 has illustrated the present invention to brake the structure of elimination state.
1: wheel; 2: wheel shaft; 3: the first drgs; 4: the flute profile gangboard on the escalator; 5: hand-push shopping cart; 6: pull bar; 7: axis; 8: the first drive links; 9: the second drive links; 10: the three drive links; 11: the four drive links; 12: the second drgs.
The specific embodiment:
Fig. 1 and Fig. 2 illustrated the prior art structure and the braking overview:
When hand-push shopping cart 5 is pulled on the flute profile gangboard 4 on the escalator, the wheel 1 of hand-push shopping cart 5 just falls in the groove in the flute profile gangboard 4 into, simultaneously, first drg 3 of wheel 1 side, second drg 12 also are pressed on the flute profile gangboard 4, obviously, Ci Shi hand-push shopping cart 5 is braked on flute profile gangboard 4 and can not have moved forward and backward.
The technology of the present invention structure after Fig. 3 (braking mode) and Fig. 4 (braking elimination state) have illustrated to improve, that is: increased mainly by pull bar 6, axis 7, adjustable brake system is through first drive link 8, second drive link 9, the 3rd drive link 10 by pulling pull bar 6, adjusting places rising and falling of second drg 12 of wheel on 1, pull bar 6 is through the 4th drive link 11, adjusting places first drg 3 on the wheel 1, can change the braking mode of hand-push shopping cart 5 on domatic elevator 4:
When hand-push shopping cart 5 has been in braking mode on domatic elevator 4, and the user is when needing to cancel this braking mode this moment, can be by manually pull bar 6 being pulled to the pass closed region by opening the zone.At this moment, by the effect by first drive link 8, second drive link 9, the 3rd drive link 10, second drg 12 is risen, and pass through the effect of the 4th drive link 11, first drg 3 is risen, braking mode is removed.
When the user pushes ideal position with hand-push shopping cart 5 on domatic elevator 4, when wishing to allow hand-push shopping cart 5 be in static braking mode, can be by pulling moving pull bar 6, pull bar 6 is pulled to and opens the zone by closing closed region.At this moment, the effect by first drive link 8, second drive link 9, the 3rd drive link 10 falls second drg 12, and passes through the effect of the 4th drive link 11, and first drg 3 is fallen.The braking of hand-push shopping cart 5 recovers, and hand-push shopping cart 5 will be with the motion that together fixes of domatic elevator.
