AI Technical Summary

Problems solved by technology

For example: after the customer has pushed the trolley to the slope-shaped elevator downstairs after shopping on the third floor, when he wants to return to the third floor to add some products, it has been impossible, because the products in the trolley already located on the slope-shaped elevator The moving device is in the braking state, and the goods on the third floor can only be replenished after going downstairs and returning to the third floor. This trouble caused by the existing technology of the trolley is annoying.
——Bringing a lot of inconvenience to customers

Embodiment Construction

[0018] figure 1 and figure 2 The prior art structure and its braking profile are illustrated:

[0019] When the shopping cart 5 was pushed onto the grooved ladder 4 on the escalator, the wheel 1 of the shopping cart 5 sank into the groove in the grooved ladder 4, and at the same time, the wheels 1 on the side The first brake 3 and the second brake 12 are also pressed on the grooved ladder plate 4. Obviously, the hand-push shopping cart 5 at this moment is braked on the grooved ladder plate 4 and cannot move forward and backward.

[0020] image 3 and Figure 4 The improved technical structure of the present invention is illustrated, that is, the main pull rod 6 and the central shaft 7 are added, and the adjustable braking system is passed through the first transmission rod 8, the second transmission rod 9, and the third transmission rod by pulling the pull rod 6. 10. Adjust the rise and fall of the second brake 12 placed on the wheel 1. The pull rod 6 passes through the f...

Abstract

The adjustable brake system for hand pushed shopping trolley features that pulling the pull rod fixed onto the middle shaft can draw the first brake via the fourth driving rod, or draw the second brake through the first driving rod, the second driving rod on the wheel shaft and the third driving rod. When the hand pushed shopping trolley is in inclined elevator, pulling the pull rod from the opening area to the closing area can brake off the shopping trolley, or pulling the pull rod from the closing area to the opening area can brake the shopping trolley.

Description

technical field [0001] The invention relates to vehicle brake technology. Background technique: [0002] The trolleys that can be seen in large and medium-sized supermarkets all have fixed braking systems. Automatic coupling makes the trolley in automatic braking state. When people want to pull it on the ramp elevator, it is impossible to return to the original floor for shopping. For example: after the customer has pushed the trolley to the slope-shaped elevator downstairs after shopping on the third floor, when he wants to return to the third floor to add some products, it has been impossible because the products in the trolley on the slope-shaped elevator are already located. The moving device is in the braking state, and only after returning to the third floor again after going downstairs, can the merchandise on the third floor be supplemented. This trouble caused by the prior art of the trolley is annoying. ——Brought a lot of inconvenience to customers. Invention c...
