Description

A shock-absorbing caster with automatic alarm when the bearing capacity exceeds the standard

technical field

The utility model relates to a wheel, in particular to a shock-absorbing caster which can automatically alarm when the bearing capacity exceeds the standard.

Background technique

Casters are a general term, including movable casters and fixed casters. Swivel casters are what we often call universal mobile wheels, which can rotate 360°; fixed casters have no rotating structure and cannot be rotated. Usually, two kinds of casters are used together. For example, the structure of the trolley is two fixed wheels on the front, and the two behind the push armrest are movable casters. The load-bearing capacity of casters is also called dynamic load when moving. The dynamic load of casters varies with the material of the wheels, and the instantaneous load-bearing capacity of casters is also different when the casters are impacted or vibrated by the load. At present, casters have been widely used in trolleys, trolley cases, medical carts and other fields. When encountering uneven and uneven roads, the casters bump and vibrate severely, which increases the wear of the casters, which reduces the service life of the casters and damages the load. . Therefore need a kind of caster that can reduce vibration when moving. The Chinese patent application number 201320201780.7 discloses a shock-absorbing caster, which belongs to the field of mechanical technology. It solves the problem that the existing industrial casters adopt shock absorbing pads and have poor shock absorbing effect. The shock-absorbing caster includes a caster bracket and a wheel connected with the caster bracket. The caster bracket includes a fixed bracket and a movable bracket. The movable bracket and the wheel are connected through a wheel shaft arranged at the center of the wheel, and the fixed bracket is used for connecting with the appliance. The fixed bracket and the moving bracket are vertically arranged and the two are hinged. The side of the fixed bracket is fixedly connected with a positioning plate, and a shock absorbing spring is arranged between the positioning plate and the end of the moving bracket. When the moving bracket rotates downward, the shock absorbing spring is compressed. When the weight of the object on the cart exceeds the weighing weight of the caster, the caster and the shock absorbing mechanism are easily damaged, and the service life is shortened. The above-mentioned patents cannot solve this problem.

Further, one end of the lower fixing part and the upper fixing part are fixed together through a pin shaft, and the shock absorbing spring is installed behind the lower fixing part through fastening bolts, and there is at least one shock absorbing spring.

Further, the display screen is inlaid on the upper fixing member, and the display screen is an LED liquid crystal screen.

Further, the status indicator light is inlaid on the lower fixing part, the status indicator light is an LED light, and there are two status indicator lights in total, and the two status indicator lights are respectively a power indicator light and a working indicator lamp.

Further, the alarm is inlaid on the upper fixing part, the alarm is a buzzer, and the sound pressure level of the alarm is 70db-90db.

Further, the storage battery is fixed on the lower fixing member by screws, and the output voltage of the storage battery is 5V.

The beneficial effect of the utility model is that: the weight of goods on the trolley can be automatically monitored while the shock is being reduced, so as to prevent the goods on the trolley from exceeding the carrying capacity of the casters and cause damage to the casters, thereby prolonging the service life of the casters.
