Description

Technical Field

[0001] The utility model relates to the technical field of casters, in particular to a caster bracket. Background Art

[0002] Casters are a general term, including movable casters, fixed casters and movable casters with brakes. Movable casters are what we call universal wheels, and their structure allows 360-degree rotation; fixed casters are also called fixed casters, which have no rotating structure and cannot rotate. Usually, the two types of casters are generally used in combination. For example, the structure of a trolley is two fixed wheels in the front and two universal wheels in the back near the push handle.

[0003] Most of the existing casters are fixed on the equipment by bolts. When the caster is damaged and needs to be replaced, the bolts need to be removed again before the caster can be disassembled and replaced. After the replacement is completed, the bolts need to be reinstalled again, which is troublesome. For this reason, we propose a caster bracket. Utility Model Content

[0027] Preferably, the surface of the connecting slide rod 4 is sleeved with a buffer spring 5 whose two ends are respectively fixedly connected to the lower end surface of the mounting plate 1 2 and the upper end surface of the mounting plate 2 12. The buffer spring 5 can provide buffering protection for the caster when the caster is in use.

[0028] Preferably, the positioning mechanism comprises a sliding frame 7 penetrating the inverted U-shaped frame 8 and fixedly connected to the penetrating portion, and a moving plate 15 is slidably connected inside the sliding frame 7. The setting of the moving plate 15 can drive the plug plate 17 to move.

[0029] Preferably, one side of the movable plate 15 is fixedly connected to a plug plate 17 which is slidably connected to the inside of a slot 16 provided on the surface of the T-shaped connecting block 9, and the other side of the movable plate 15 is fixedly connected to a pull rod 13 which passes through the sliding frame 7 and is slidably connected to the passing part.

[0031] The specific working principle and use method of the utility model are as follows:

[0032] The utility model provides a caster bracket, which, when in use, is fixedly connected to the lower end of the equipment through the mounting blocks 1 on both sides of the mounting plate 2 by bolts. When the caster is in use, the bumping force received by the caster when moving can be buffered under the action of the damping rod 3, the connecting slide rod 4 and the buffer spring 5, thereby protecting the caster. When the caster is damaged and needs to be disassembled and replaced, it is only necessary to directly pull the pull frames 6 on both sides of the inverted U-shaped frame 8, so that the pull frame 6 pulls the pull rod 13, so that the pull rod 13 pulls the moving plate 15 to slide inside the slide frame 7, so that the moving plate 15 can be brought The movable plug plate 17 is separated from the slot 16. After separation, the support frame 11 can be pulled to separate the T-shaped connecting block 9 from the inverted U-shaped frame 8 and the missing slot 10. When installing a new caster, the T-shaped connecting block 9 is slid into the missing slot 10 and the inverted U-shaped frame 8, and then the pull frame 6 is released. The movable plate 15 can be moved in the opposite direction inside the sliding frame 7 under the reset and extension action of the compression spring 14, so that the plug plate 17 can be slid into the slot 16, so that the T-shaped connecting block 9 is limited inside the sliding frame 7, thereby completing the limited installation of the caster, without the need to disassemble the bolts connected to the lower end of the equipment, thereby improving the installation efficiency.
