Caster pad

Technical Field

The utility model belongs to the technical field of machinery, and relates to a caster pad.

Background

Casters are a common hardware fitting, and are usually mounted on the bottom of furniture, carts, instruments and equipment, etc., so that the instruments can be flexibly moved. In order to turn the implement when it encounters a corner, the casters are further arranged to be rotatable through 360 °. However, after the implement has been moved to the designated position, it is again required that the implement remain stationary to avoid unnecessary displacement. Therefore, some casters are provided with a brake structure, and wheels of the casters are fixed with the brackets of the casters through the brake structure so that the casters cannot rotate. However, this merely changes the friction between the wheels and the ground from rolling friction to sliding friction, which does not allow the wheels of the castor to be positioned completely on the ground, and displacement may still occur when the implement is subjected to a certain force.

For this, there is a caster pad made of a rubber material, on the upper side of which a positioning groove is provided, and when in use, the implement is lifted and placed on the ground, and then the implement is lowered and the wheels of the casters are inserted into the positioning grooves of the caster pad (the implement having several casters and several caster pads are used), thereby positioning the casters to prevent the implement from moving. However, it is inconvenient to use because it requires lifting the implement each time it is used and also requires lifting the implement when the caster is to be released, especially because some implements themselves are heavy.

The utility model aims to solve the problems in the prior art, and provides a castor pad which solves the problem of inconvenient use.

The aim of the utility model can be achieved by the following technical scheme:

the caster pad comprises a body and is characterized in that the body comprises a blocky substrate and two positioning parts which are vertically and fixedly connected to the front side of the substrate and are in strip shapes, the heights of the two positioning parts are the same, the bottom surfaces of the positioning parts are flush with the bottom surface of the substrate, the left side and the right side of the substrate are respectively provided with a concave groove, and the concave groove on the left side is concave towards the right side and the concave groove on the right side is concave towards the left side.

When the caster is used, the body is placed on the ground in the direction of the two positioning parts perpendicular to the wheels in the caster and pushed to the caster, and the two positioning parts are abutted against the outer surfaces of the lower parts of the wheels of the caster to clamp the wheels so that the wheels are positioned and cannot rotate. When the positioning is needed to be released, the user only needs to sink the thumb and the index finger into the concave grooves respectively, and then apply acting force to pull out the body in the direction away from the wheels, so that the body is separated from the wheels of the casters. Through such arrangement, the caster pad does not need to be lifted up by a user to be matched with the appliance for use, and the convenience of use is greatly improved. Further, through the setting of sunken groove, increased the impetus that can outwards draw the body for the user to make the user can remove the location to the truckle with the mode of outwards pulling out the body, improved user's operation convenience greatly.

In the caster pad, the bottom walls of the two concave grooves are cambered surfaces.

The bottom wall of the concave groove is set to be an arc surface, so that the concave groove can be matched with the shape of a finger, and the operation of a user when pulling out the caster pad is more convenient.

In the caster pad, the two concave grooves are symmetrically distributed on the left side and the right side of the base body, the concave grooves are close to the rear side wall of the base body, and the two concave grooves respectively enable the left rear side and the right rear side of the base body to form lugs.

When the trundle needs to be positioned, the user can push the whole trundle pad forwards from the two ears by thumb and forefinger respectively; when the positioning of the contact castor is needed, the thumb and the index finger are respectively embedded into the two concave grooves by a user, and then the whole castor pad is pulled out by taking the two ears as the force points.

In the caster pad, the left side wall of the left positioning portion and the right side wall of the right positioning portion are both inclined and opposite in inclination direction, and the distance between the left side wall of the left positioning portion and the right side wall of the right positioning portion is gradually increased from top to bottom.

Through the arrangement, the two positioning parts form a state with small upper part and big lower part, so that more reliable positioning can be formed on the castor.

In the above caster pad, the body is provided with a plurality of hollowed-out grooves at the bottoms of the two positioning parts and the bottom of the base body.

The setting in routing groove can increase the frictional force between whole body bottom surface and the ground, and the body is difficult for shifting subaerial, has further improved the location effect to the truckle.

In the caster wheel pad, one side of each of the two adjacent positioning parts is provided with an arc-shaped positioning surface, the two positioning surfaces are concentrically arranged, the upper edge of the front side surface of the base body is inclined backwards relative to the lower edge, and the two positioning surfaces are respectively in arc transition with the front side surface of the base body.

When two locating parts are clamped on two sides of a wheel of the caster, the locating surfaces on the two locating parts are respectively attached to the wheel surface of the wheel, so that the locating effect on the caster is better.

In the caster pad, the body is made of LDPE material.

Compared with the prior art, this truckle pad is through setting up the body to including being massive base member and two perpendicular linking firmly in the base member front side and all be banding location portion, the bottom surface and the base member bottom surface of the same and location portion of height of two location portions flush for the truckle pad can be with the truckle location or remove the location of truckle with the flat push mode, need not to make the truckle pad need not to lift up the cooperation by the user again and use the utensil, has improved the convenience of use widely.

Further, through the setting of sunken groove, increased the impetus that can outwards draw the body for the user to make the user can remove the location to the truckle with the mode of outwards pulling out the body, improved user's operation convenience greatly.
