CN2441663Y - Automatic balance load stopped universal castor - Google Patents

Abstract

The utility model relates to a universal caster with automatic balance load stop. The caster is installed on the ground support point of movable office equipment and household appliances, and is provided with an adjustment positioning ring and a balance pressing spring. When the placed ground is uneven, each caster can automatically balance and adjust its height under the action of the balance compression spring, so that the office equipment and household appliances can be placed stably. When it is necessary to stop after bearing a certain load, by adjusting the fixed position of the positioning ring, the caster will automatically stop when it exceeds the set load force, ensuring the fixed position of office equipment and household appliances when they are in use.

Description

Swivel castors with self-balancing load stops

The utility model belongs to a caster matched with office equipment and furniture, which can be moved or fixed according to needs, and can automatically adjust and stabilize a universal caster with automatic balance and load stop.

Install casters on office equipment and furniture to facilitate location movement. The currently used casters have two types of one-way rolling and universal rolling (utility model patents designed by Sun Guangjun and Chao Yueyun. A universal caster, patent number: ZL 97213484.0; utility model patents designed by Pengcuo. Telescopic casters, patent No.: ZL98229935.4). All the casters currently in use are designed and installed with multiple casters to realize the function of movement; but on uneven ground, the height of the casters cannot be adjusted, so the placement is not stable, or due to the change of use or the touch of external force, it cannot be kept fixed when in use. Location.

The purpose of the present invention is to design a device that can automatically adjust the balance on uneven ground, and can be fixed for use, and will not affect normal work due to changes in posture or touches of external forces during use; Wide and self-balancing load-stop swivel casters.

The universal caster with automatic balance and load stop of the present invention is composed of an adjusting screw, a nut, a lock nut, an adjusting positioning ring, a balance compression spring, a pressure bearing, a retaining piece, a caster seat, a brake detent, a wheel axle, and a universal wheel. and so on. The column end of the adjustment screw is installed in the steering hole of the caster seat and fixed with a stopper, and the brake detent is placed on the bottom surface of the column end; the universal wheel is fixed on the caster seat by the wheel shaft; the pressure bearing, the balance spring, and the adjustment positioning ring , lock nut and nut are loaded into the other end of the adjusting screw in turn, and then the adjusting screw is installed on the foot of office equipment or furniture and locked with the nut. After determining the size of the load, rotate and adjust the positioning ring to apply force to the balance compression spring to ensure that the column end of the adjusting screw rod moves down after receiving the load so that the brake detent contacts the universal wheel to produce a stop effect; and when the ground is uneven, Due to the function of the balance compression spring, the height of each caster is automatically balanced and adjusted to keep the office equipment or furniture stable.

The advantages of the universal caster wheel with automatic balance load stop of the present invention are: each caster wheel can be automatically adjusted according to the unevenness of the ground to maintain the stability of office equipment or furniture; Bearing the size of the load, it can stop by itself when it is loaded, preventing displacement caused by changes in posture or external forces, and ensuring a stable position during work.

The self-balancing load-stop universal caster of the present invention is provided by the following embodiments and accompanying drawings.

Fig. 1 is a combined schematic diagram of the self-balancing load-stop universal caster of the present invention.

Fig. 2 is a schematic view of the self-balancing load-stop swivel caster of the present invention during balancing.

Fig. 3 is a schematic diagram of the self-braking of the self-balancing load-stop universal caster of the present invention under load force.

The present invention will be described in detail below in conjunction with FIG. 1 , FIG. 2 and FIG. 3 .

The universal caster with automatic balance load stop of the present invention is composed of an adjustment screw 1, a nut 2, a lock nut 3, an adjustment positioning ring 4, a balance compression spring 5, a pressure bearing 6, a catch 7, a caster seat 8, a stopper Child 9, axle 10, universal wheel 11 form.

The stop detent 9 is fixed on the bottom surface of the cylindrical end of the adjustment screw 1, inserted into the steering hole of the caster seat 8 after being loaded into the baffle piece 7, and the universal wheel 11 is installed into the caster seat 8 with the wheel shaft 10, the work of the stop detent There is a certain gap between the surface and the universal wheel 11 to ensure the normal rotation of the universal wheel 11; the pressure bearing 6, the balance spring 5, the adjustment positioning ring 4, the lock nut 3, and the nut 2 are sequentially loaded into the adjustment screw 1, and then the Adjusting screw rod 1 is installed on the supporting point of office equipment and furniture and is locked with nut 2 . After installation, determine and adjust the upper and lower positions of the positioning ring 4 according to the magnitude of the load force, so as to ensure that when the office equipment or furniture exceeds the set load force, the stop detent 9 is in close contact with the universal wheel 11 to play the role of stop , and finally turn the lock nut 3 in the opposite direction to lock and adjust the positioning ring 4.

When the office equipment and furniture do not exceed the set load force, the balance spring 5 will bounce the adjusting screw 1, so that the stop detent 9 is separated from the universal wheel 11, and the universal wheel 11 can rotate freely, realizing office equipment, The movement of furniture; when the office equipment and furniture exceed the set load force in use, the stop detent 9 is in close contact with the universal wheel 11 to play the role of stop.

When the ground is uneven, the balance compression spring 5 of each caster automatically balances to adjust the height of the adjustment screw 1, so that office equipment and furniture are automatically kept stable.

The self-balancing load-stop universal caster of the present invention is suitable for various office equipment and furniture, and can also be installed and used on devices and equipment that need to be moved and can be stopped under set conditions in industry and commerce.
