Description

Buffer transport trolley

Technical Field

The utility model relates to the field of trolleys, in particular to a buffer transfer trolley.

Background

A good electronic screen in electronic information equipment such as a mobile phone and a tablet can improve the experience of a user, but the electronic screen can be subjected to a plurality of working procedures in production, and semi-finished glass screens are required to be transferred among the working procedures, and a transfer trolley is generally used for transferring.

In the patent document with the publication number of CN214985508U, a multifunctional transfer trolley is disclosed, and the structure of the multifunctional transfer trolley comprises an electric telescopic rod, a gear, a sliding block, a storage plate and other structures, the gear is driven by the electric telescopic rod, the gear enables the sliding block to slide, the sliding of the sliding block leads to the inclination of the storage plate, and the inclined storage plate is more convenient in the process of fine material feeding and discharging. However, the object placing plate of the trolley is rigidly connected with the frame of the trolley, and the trolley is not provided with a buffer structure, if the glass screen is transported by using the trolley which is rigidly connected, collision occurs in the transportation process, the object placing plate is stressed with larger force instantly, so that the glass screen on the object placing plate collides with the frame, the damage of the screen is caused, the defective rate is increased, and the production cost of enterprises is increased.

Disclosure of Invention

The utility model aims to provide a buffer transfer trolley which is used for solving the technical problems that the glass screen is damaged due to collision in the transfer process, the defective rate is increased and the production cost of enterprises is increased.

In order to solve the technical problems, the technical scheme provided by the utility model is as follows: a buffer transfer trolley comprises a hand push rod, a frame and universal wheels; the frame is composed of an upper frame, a lower frame and a vertical prism fixedly supported between the upper frame and the lower frame, a circular ring is fixedly connected to the vertical prism, one end of the circular ring is movably connected with one end of a spring, and a placing plate is fixedly connected to the other end of the spring.

The working principle and the beneficial effects of the technical scheme are as follows:

1. working principle:

the spring structure between the placing plate and the frame has higher rigidity, the wire diameter of the spring is larger than 5mm, the vibration amplitude is not very large when the trolley collides, the vibration is rubbed with the air, the vibration energy can slowly disappear along with the air resistance, and part of energy can be slowly released in the connection friction between the spring and the frame piece and the spring, so that the instantaneous force is buffered.

2. The beneficial effects are that:

in the prior art, when the handcart carelessly collides, a glass screen placed on the handcart is subjected to strong force instantly, so that the glass screen is vibrated and collided, and the glass screen is damaged. When external force is applied to the frame, the springs deform, so that the instant force brought by collision is slowed down, and the glass screen on the placing plate is protected from being damaged.

Further, the vertical prism is provided with a plurality of equally distributed circular rings. When the glass screens with different sizes are placed on the cart, and the placing plates are required to be adjusted up and down, the placing plates are taken down by utilizing the movable connection of the hooks on the springs and the circular rings on the cart frame, the springs are hooked on the proper heights, the heights of the placing plates are changed, and therefore the upper space and the lower space of the cart are adjusted.

Further, a rubber handle is arranged on the hand push rod, and a plurality of spherical protrusions are arranged on the handle. The specific heat capacity of the rubber is larger than that of iron, the ice feeling of the rubber grip in cold seasons is low, the use experience of staff is better, and the friction force of the grip is increased due to the spherical protrusions, so that the grip is better to grip.

Further, a plurality of strip-shaped anti-slip strips are arranged on the placing plate. The anti-slip strips on the placing plates can increase friction between the placed objects and the placing plates and prevent the placed objects from sliding off.

Furthermore, an anti-collision block is arranged on the bottom cross beam of the frame, and the anti-collision block is made of rubber. The anti-collision block is like a bumper of an automobile, can effectively protect a frame in collision, is made of rubber, has a damping effect in collision, and can buffer a placing plate.
